Cluster algebras associated to quivers are additively categorified by categories modeled on quiver representations. Stability conditions and scattering diagrams of these categories are remarkably linked with the corresponding cluster algebras. I will first introduce scattering diagrams valued in graded Lie algebras in full generality and explain Kontsevich-Soibelman's classification theorem. A canonical cone complex structure of a scattering diagram will be given. Then I will define Bridgeland's stability scattering diagrams associated to quiver with potentials and explain how they can be used to study the corresponding cluster algebras.

If the ascending sort matches the current value of X coordinates, the right-swipe condition is set. Conversely, if the descending sort is matched, the left-swipe condition is set. The eventString variable holds this condition and will be executed as shown below.
Listing 5. Main logic continued, event execution
 # reset all data points, yes you can have 0 fingers at x,y
 _USER_ = ();
 _USER_ = ();
 _USER_ = ();
 }# if not one or two or three fingers
 # only process one event per time window
 if( $eventString ne "default" )
 if( abs(time - $eventTime) > 1 )
 $eventTime = time;
 SendKeys( "$eventString");
 }_TAG_ enough time has passed
 $eventString = "default";
 }_TAG_ non default event
}_TAG_ line in
At this point, each data structure for pinch or swipe is reset if three fingers are not detected. If an event has been set and the current time is far enough from the last event execute time, a new event is executed. The SendKeys subroutine sends the appropriate event (Alt+left or right arrow) to the currently focused application. As shown in the demo video (see Resources), these three-finger gestures are used to move forward and backward in the browsing history.
Pinch gestures
Pinch gestures are substantially more complicated to detect, especially on the older hardware used to develop this article. Monitoring the open-and-close gestures in real time using a tool like kst is a helpful way to extract relevant features from the TouchPad data. Insert the code in Listing 6 at line 65 (above the else) to begin the close-pinch detection section.
Listing 6. Close-pinch detection
 }elsif( $f eq "2" || $f eq "1" )
 # accept 1 or 2 finger entries as part of pinch section
 _USER_ = ();
 push _USER_, $x;
 push _USER_, $y;
 if( _USER_ > 50 )
 if( (getStrAvg(\_USER_) > $closeSt && getStrAvg(\_USER_) > $closeSt) &&
 (getEndAvg(\_USER_) < $closeEn && getEndAvg(\_USER_) < $closeEn) )
 # wide to narrow detected, now search for enough 'wiggle'
 my $tenX = 0;
 my $tenY = 0;
 for my $each( _USER_[40..49] ){ $tenX += $each }
 for my $each( _USER_[40..49] ){ $tenY += $each }
 $tenX = $tenX / 10;
 $tenY = $tenY / 10;
 my $diffX = 0;
 my $diffY = 0;
 for my $each( _USER_[40..49] ){ $diffX += abs( $each - $tenX ) }
 for my $each( _USER_[40..49] ){ $diffY += abs( $each - $tenY ) }
 # ctrl - decrease font size
 if( ($diffX+$diffY) > 80 ){ $eventString = "^({-})" }
 _USER_ = ();
 _USER_ = ();
 _USER_ = ();
 }_TAG_ x and y in range
 }_TAG_ enough data for 50 close pinch detection
One or two fingers are accepted as part of the pinch-detection step to enhance the overall tracking. Slightly offset timings of touches and releases, as well as moving one finger slightly off the TouchPad during pinch movements are dealt with more easily by accepting one or two touches as part of the pinch movement.
After 50 or more data points have been collected, the average start and end positions of the past 50 data points are computed. The third if statement performs four separate checks to ensure that the start and end points are in the correct parts for a close-pinch detection — specifically if the X and Y averages for the start points need to be more than the close-pinch start points. That is, the positions of the fingers need to be in the corners. Conversely, the end points need to be within the close-pinch end points. getStrAvg and getEndAvg create averages of the three start and end points, which are a more reliable data point for the check.
True multitouch capability would allow for an X and Y coordinate reading of each finger position. The Synaptics hardware available does not have this capability, but does provide consistent behaviors as the two-finger touch points are "averaged" into one output for the synclient program. Monitoring the output of the synclient program shows that when two fingers touch in the southwest and northeast corners, the values rapidly go from the corners to the center of the TouchPad. If the fingers are kept in the corners, the synclient output shows the X and Y coordinates staying near the center. As the fingers are moved toward the center, this automatic averaging shows slight perturbation. The wiggle in the data is detected by the section of code above to indicate a close pinch, as opposed to the synthetic averaging of data points when the fingers are held in the corners without movement.
Ten of the trailing values of the X and Y coordinate history are averaged together. The difference between each of the last 10 trailing values and the average for the last 10 is then computed. If the overall difference is great enough (greater than 80 in this case), enough wiggle has been detected and the close-pinch condition is set in eventString.
Add the code shown in Listing 7 at line 103 (below the close-pinch 50-point if closing bracket ) for open-pinch detection.
Listing 7. Open-pinch detection
 _TAG_ pinch requires substantially fewer data points
 if( _USER_ > 10 )
 if( (getStrAvg(\_USER_) < $openSt && getStrAvg(\_USER_) < $openSt) &&
 (getEndAvg(\_USER_) > $openEn && getEndAvg(\_USER_) > $openEn) )
 # ctrl + increase font size
 $eventString = "^({+})";
 _USER_ = ();
 _USER_ = ();
 _USER_ = ();
 }_TAG_ absx and absy
 }_TAG_ enough data
In addition to requiring substantially fewer data points for reliable detection of an open pinch, the wiggle-detection step is not necessary. With real-time monitoring using a program like kst, synclient output shows a much broader range of data points collected for the open-pinch gesture. The automatic averaging of the two fingers positions does not produce a large influence on the synclient X and Y coordinates during an open-pinch gesture. Therefore, it is no longer necessary to recognize the wiggle for accurate gesture detection. Listing 8 shows the getStrAvg and getEndAvg averaging subroutines.
Listing 8. Two averaging routines
sub getStrAvg
 my $arrRef = $_[0];
 my $val = (@$arrRef[0] + @$arrRef[1] + @$arrRef[2]) / 3;
 $val = abs( $val - $centerTouchPad );
sub getEndAvg
 my $arrRef = $_[0];
 my $val = (@$arrRef[@$arrRef-3] + @$arrRef[@$arrRef-2] +
 @$arrRef[@$arrRef-1]) / 3;
 $val = abs( $val - $centerTouchPad );
Place the code shown in Listing 8 at line 144 (the end of the file) to complete the program. getStrAvg and getEndAvg are responsible for returning the average of the first three array elements and the average of the last three array elements, respectively.
Activating the program is a simple matter of running the command perl Bring your Web-browsing window into focus and try moving through the browsing history with left and right swipes. Note that due to the smaller track-pad size, as well as the inherent limitations of the ability of the hardware, it may take some practice before you can reliably trigger gesture events. Consult the demonstration video (see Resources) for examples of hand movements that work on the author's ThinkPad. If you want to re-enable TouchPad "mouseiness," run synclient TouchPadOff=0 after exiting the program.
Conclusion and further examples
Linkage between gestures and events
Keep in mind that the SendKeys command will send the appropriate commands (Alt+Left, Ctrl+/-, etc.) to the currently focused application, regardless of the functionality this triggers. A relatively simple change to consider is specifying different keystrokes or mouse events to send to an application based on the window name.
Further examples and modifications
The combination presented here of analysis and processing of synclient output and synthetic X event creation is only one path for added functionality to the Synaptics TouchPad. Consider adding additional gesture recognition, such as pinch rotate through further feature extraction from the synclient output. Alternatively, modify the Synaptics driver source code to support additional features at the kernel level and rewrite applications to take better advantage of these new input channels.

Oracle RAC
In database computing, Oracle Real Application Clusters (RAC) — an option for the Oracle Database software produced by Oracle Corporation and introduced in 2001 with Oracle9i — provides software for clustering and high availability in Oracle database environments. Oracle Corporation includes RAC with the Standard Edition of Oracle Database (aka Baby RAC), but makes it an extra-charge option for the Enterprise Edition.
Oracle RAC allows multiple computers to run Oracle RDBMS software simultaneously while accessing a single database, thus providing a clustered database.
In a non-RAC Oracle database, a single instance accesses a single database. The database consists of a collection of data files, control files, and redo logs located on disk. The instance comprises the collection of Oracle-related memory and operating system processes that run on a computer system.
In an Oracle RAC environment, two or more computers (each with an instance) concurrently access a single database. This allows an application or user to connect to either computer and have access to a single coordinated set of data.
On 10R2 if the Oracle binaries are installed with the RAC, one can't use those binaries to start Oracle Instance if CRS is not running, so in case when one needs to start the instance without CRS one needs to rebuild the oracle and it's libraries to start the instance.
To turn off RAC
# link the oracle libraries
$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk rac_off
# rebuild oracle
$ cd $ORACLE_HOME/bin
$ relink oracle
To turn on RAC
# link the oracle libraries
$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk rac_on
# rebuild oracle
$ cd $ORACLE_HOME/bin
$ relink oracle

instant pot timer not starting
The Instant Pot Says On No Timer( What It Means And Solution)
When you get an instant pot, you get an appliance that can cook different food. That way, you save yourself from buying many appliances for cooking different food and end up saving some space in the kitchen.
The best part is the appliance is easy to use. But just like any other thing once in a while you may come across some challenges trying to operate it. An example, the timer may at times seem like it's not working, but at the same time the instant pot reads ON.
When this happens, you don't have to call a technician or start looking for the warranty card to take the pot back. These are some minor issues you can fix yourself without spending anything. This article is here to help you understand why they happen and how you can fix the issue.
Why is Your Instant Pot Timer Not Starting?
The instant pot is easy to use. It has direct functions with preset time. The operation required is minimum as compared to other appliances. If the timer is not starting it's probably something minor or, normally, it's just taking its time to start.
Gaining pressure
When using the pressure cooking function, after you put the food and close the lid, the pot will read 'ON'. But it takes a while to start the pot as it is first gaining pressure.
The process of gaining pressure is different with different foods. Some will gain pressure and start the timer fast, while others will take a lot of time to gain pressure. At this point, there is nothing much you can do as long as the food has water in it give it time as the timer will start with time.
Blown fuse
If the instant pot timer is not starting completely, it could be a blown fuse. Instant pots have an electronic fuse that helps in controlling the flow of current in the instant pot. When the current is high than required, the fuse cuts the current.
In case the fuse is malfunctioning, it may lead to the timer not starting. An example, it may interfere with the current going to the pot and supply less power and cause the timer not to start but the display reads ON.
In extreme cases, the timer may not start at all.
If this is the case, buy another fuse and replace the old one and your instant pot will work just fine. You can check on the manual on how you should go about replacing the fuse.
Not Plugged in Properly
In case the instant pot is not starting at all you should start by checking if the instant pot is plugged in and if yes, if it's plugged in properly.
Most instant pots come with a detachable cable. At times the cable may not be connected, and you don't know. So in case it's not starting, start by checking the connection to ensure it is connected.
The plug could also be loosely attached to the pot and hence not enough current getting to the instant pot system. At this point, the pot may read on, but the current getting in is not enough to start the timer.
Before starting an instant pot, ensure it is plugged in and tightly plugged to ensure it functions smoothly.
Not connected or a bad connection
Instant pots need electricity to function. If there is no power connection or the power connection is not smooth, the pot may not start or even start, but the timer may not function.
In case you experience such a problem, check the connection to see if it's smooth and uninterrupted. If that's the case, wait for the connection to get back and use the pot then.
The power flow is inconsistent
We all have experienced inconsistent power supply. One minute there is power the next there is no the next there is, but it comes in low voltage, and all the bulbs are dim.
When this is happening, not only the bulbs are affected, but appliances too are affected. An example, the instant pot may fail to start or start but not open the timer.
When this happens, all you can do is wait for the power to get back to its normal voltage to operate.
The water is taking time to heat
After you have filled the instant pot with food and water and closed the lid for pressure cooking, the next step is to start the pot for it to cook. But the timer doesn't go on immediately.
At this point, the display may be reading on, but the timer is yet to start. The pot is taking time to heat the water so it can produce the steam that helps in creating pressure in the pot that helps in the cooking process.
Confirm with the manual
If you have tried all the above and nothing seems to work, it's time to confirm with the manual. Check on the troubleshooting section to see if there is something that can help.
Instant pots are not exactly appliances and for that case don't require experts to help with the minor issues. After going through the manual, you may find something you can do to fix the pot and the timer.
Reset or restart the instant pot
When you are cooking two meals in a roll, you may need to reset the instant pot before cooking the next meal. This is because after cooking the first meal, the pot remains on the temperature and the time you had previously set.
All you need is to reset the instant pot, and the timer will work just fine and cook your food smoothly.
The setting is out
The setting on the instant pot could be out of order and thus causing the on but no timer issue. There have been many complaints about this. It could be someone who interfered with the settings unknowingly.
The solution is pressing the reset button on the instant pot, and the pot will work just fine. If you can't see the reset button as different models have different structuring, you can check on the manufacturing guide to see how you can restart the instant pot.
An instant pot takes around 10 to 15 minutes to reheat every time you are using the pressure cooking function. The time is for the pot to heat up and bring the pressure level up.
After that time, it is when the timer start. Every time you are cooking a meal that requires a 5 minutes timer, you should have in mind it will take more than that due to the time used in preheating.
Tips to have in mind when using an instant pot
Immediately you get your instant pot the first thing you should do is read the manufacturer's manual and ensure you understand it.
The instant pot comes with many different buttons that all perform different tasks. If you haven't read the manual, the buttons can be confusing, and the whole cooking process can get stressful and frustrating.
Pressure cooking uses water to produce steam which in return helps in raising the pressure levels in the pot that helps in the cooking process. This means, ensure you add water to the food no matter what you are cooking. At least add a cup and a half to the food to prevent burning the food.
Every time you are setting your cooking time with an instant pot, always add a few minutes to the cooking time as the pot takes time to preheat the pot and also takes time in releasing the steam naturally.
An instant pot tends to boil food so good. At some point, it can lead to overcooking of food. Due to this, ensure you set the exact right time. If it means releasing the steam manually do so as the time you take to release the steam naturally the cooking process is still happening just that it's a little bit slow.
Do not be afraid to explore with your instant pot, try a different recipe, and change temperatures and timing. That's how you come up with the best recipe and food. All you need is to be careful and don't try recipes that are prohibited like deep frying.
The convenience that comes with an instant pot is on the next level. But at the same time, you may experience some minor issues. The good part is you don't need to get someone else to fix the problems for you. You can do it yourself.
Using the information above, you can fix a timer to work. But in case the issue becomes major, and you are not sure you can handle the issue get an expert to avoid causing more damage.

In this article, we introduce a numerical framework for quantum tomography and entanglement quantification of three-qubit generalized Werner states. The scheme involves the single-qubit SIC-POVM, which is then generalized to perform three-qubit measurements. We introduce random errors into the scheme by imposing the Poisson noise on the measured photon counts. The precision of state estimation is quantified and presented on graphs. As a special case, we compare the efficiency of the framework for the pure three-qubit generalized Werner state and the W state. The reconstructed states are presented graphically and discussed.

Extrinsic thermoelectric response of coherent conductors ( _URL_ )

Rafael S\'anchez, Cosimo Gorini and Genevi\'eve Fleury(参考訳) 走査型プローブに接触したコヒーレント導体の熱電応答について検討した。 プローブとのカップリングは、制御された熱電流をシステムに局所的に注入し、輸送係数の干渉パターンを誘導できるという二重効果を持つ。 これは、導体が電子-ホール対称性を効果的に破壊せず、先端が電荷を注入しても、多端子熱電効果を生成するのに十分である。 非相互作用電子の単純なモデルを考えると、ホットプローブ先端の位置によって変調される非局所的な熱電応答と、熱電ダイオード効果をもたらす非相反的な縦応答を見出す。 脱落と準弾性散乱の効果に関する別の研究は、関連する様々なメカニズムについてさらなる洞察を与える。
We investigate the thermoelectric response of a coherent conductor in contact with a scanning probe. Coupling to the probe has the dual effect of allowing for the controlled local injection of heat currents into the system and of inducing interference patterns in the transport coefficients. This is sufficient to generate a multiterminal thermoelectric effect even if the conductor does not effectively break electron-hole symmetry and the tip injects no charge. Considering a simple model for noninteracting electrons, we find a nonlocal thermoelectric response which is modulated by the position of the hot probe tip, and a nonreciprocal longitudinal response which leads to a thermoelectric diode effect. A separate investigation of the effects of dephasing and of quasielastic scattering gives further insights into the different mechanisms involved.

Hedayat Alghassi, Amol Deshmukh, Noelle Ibrahim, Nicolas Robles, Stefan Woerner, Christa Zoufal(参考訳) 確率微分方程式の多次元系から得られるファインマン・カック偏微分方程式を解くための変分量子想像時間進化に基づくアルゴリズムを提案する。 この目的のために、Feynman-Kac偏微分方程式(PDE)とWick-rotated Schr\"{o}dinger equationの対応を利用する。 変分量子アルゴリズムによって得られる$(2+1)$ 次元ファインマン・カック系の結果は、古典的なodeソルバとモンテカルロシミュレーションと比較される。 古典的手法と量子変分法との間には、6 と 8 のキュービットの例を示す顕著な一致が見られる。 確率分布を保存する PDE の非自明な場合、$\ell_2$-norm を保存するのではなく、進化を通して解をほぼ正規化するのに効率的なプロキシノルムを導入する。 この手法に関連するアルゴリズムの複雑さとコスト,特に解の性質の抽出について検討した。 定量的ファイナンスやその他のPDE分野における今後の研究課題についても論じる。
We propose an algorithm based on variational quantum imaginary time evolution for solving the Feynman-Kac partial differential equation resulting from a multidimensional system of stochastic differential equations. We utilize the correspondence between the Feynman-Kac partial differential equation (PDE) and the Wick-rotated Schr\"{o}dinger equation for this purpose. The results for a $(2+1)$ dimensional Feynman-Kac system obtained through the variational quantum algorithm are then compared against classical ODE solvers and Monte Carlo simulation. We see a remarkable agreement between the classical methods and the quantum variational method for an illustrative example on six and eight qubits. In the non-trivial case of PDEs which are preserving probability distributions -- rather than preserving the $\ell_2$-norm -- we introduce a proxy norm which is efficient in keeping the solution approximately normalized throughout the evolution. The algorithmic complexity and costs associated to this methodology, in particular for the extraction of properties of the solution, are investigated. Future research topics in the areas of quantitative finance and other types of PDEs are also discussed.

Marco Di Liberto and Andreas Kruckenhauser and Peter Zoller and Mikhail A. Baranov(参考訳) 物理系におけるトポロジーの概念は、大きな摂動のクラスに影響を受けない非局所順序の存在と関係している。 これはシステムの振る舞いに堅牢性をもたらし、新しいフォールトトレラントなアプリケーションを開発するための基盤となり得る。 極性双極子粒子のアレイにおけるフォノン様集合モードの多種多様なトポロジー関連現象の設計と研究について論じる。 これらのモードは振動励起をコヒーレントに伝播させ、その平衡位置の周りの粒子の振動に対応する。 これらのシステムは, 外部偏光場の配向を介して相互作用の異方性を制御することで, 選択した結晶構造を持つ単一実験装置において, 幅広いトポロジ効果を調査するための, 特異かつ汎用的なツールであることを示す。 この結果から, 双極子粒子の配列は, 音波モードによるトポロジカル現象を調査するための有望な統一プラットフォームを提供することが示された。
The notion of topology in physical systems is associated with the existence of a nonlocal ordering that is insensitive to a large class of perturbations. This brings robustness to the behaviour of the system and can serve as a ground for developing new fault-tolerant applications. We discuss how to design and study a large variety of topology-related phenomena for phonon-like collective modes in arrays of ultracold polarized dipolar particles. These modes are coherently propagating vibrational excitations, corresponding to oscillations of particles around their equilibrium positions, which exist in the regime where long-range interactions dominate over single-particle motion. We demonstrate that such systems

First the context. There are two similar words that cannot be confused:
- Millar → Conjunto de mil unidades. → Set of one thousand elements.
- Millón → Mil millares. → One million.
I've seen a couple of times the word millar used when millón should be used, I think because the former is less used since there are other ways to express its meaning, e.g.:
Millares de personas salieron a las calles
Miles de personas salieron a las calles
Thousands of people marched on the streets.
My question is the following:
Is it advisable to use miles instead of millares to avoid confusion, or is their difference actually understood among Spanish speaking people?

text: We propose an approach for estimating the probability that a given small target, among many, will be the first to be reached in a molecular dynamics simulation. Reaching small targets out of a vast number of possible configurations constitutes an entropic barrier. Experimental evidence suggests that entropic barriers are ubiquitous in biomolecular systems, and often characterize the rate-limiting step of biomolecular processes. Presumably for the same reasons, they often characterize the rate-limiting step in simulations. To the extent that first-passage probabilities can be computed without requiring direct simulation, the process of traversing entropic barriers can replaced by a single choice from the computed ("first-passage") distribution. We will show that in the presence of certain entropic barriers, first-passage probabilities are approximately invariant to the initial configuration, provided that it is modestly far away from each of the targets. We will further show that as a consequence of this invariance, the first-passage distribution can be well-approximated in terms of "capacities" of local sets around the targets. Using these theoretical results and a Monte Carlo mechanism for approximating capacities, we provide a method for estimating the hitting probabilities of small targets in the presence of entropic barriers. In numerical experiments with an idealized ("golf-course") potential, the estimates are as accurate as the results of direct simulations, but far faster to compute.


Shift The Energy For Your Success
Updated: Jun 17, 2020
How much time do you spend setting up the energy of your environment? It is well known that your environment influences your behaviour. You are an energetic being living in an energetic world. You are constantly responding or reacting to your environment. Why not shift the energy for your success. You have the ability to do it!
Colours, for example, are a fascinating blend of wavelength and electromagnetic radiation. They can have a great impact on an environment. Jacob Olesen, in his article '7 Best Colours For Healing' says 'healing colours are the colours that influence mood, calm the nervous system and make the environments less provoking and peace inducing.' Orange is a great colour for inspiring creativity and red will evoke vitality.
Aromas can also be used to create a positive and productive environment. They can have a powerful impact on cognitive functions. Peppermint is known to increase alertness. Lemongrass will lower anxiety. Lemon is known to improve performance and rosemary has been proven to significantly improve memory. Consciously incorporating smells into your environment can assist your body to optimise the time in that space. How awesome is that!
One of my most favourite ways to influence an environment is to use the process of visualisation. Many office spaces, conference rooms, hotel rooms and hospital rooms, to name a few, have no access to fresh air often relying on air-conditioning to keep the air 'fresh'. When spaces are unable to access fresh air, energy builds up. If this energy is not cleared it becomes dense impacting on you and your ability to function at your optimum whether you are conscious of it or not. The great news is, you have the ability to shift the energy.
For me, the process of visualisation simply means using your imagination, and we've all got one of those! Did you know that your thoughts have a powerful ability to create reality. Dr Bruce Lipton was instrumental in shining a light on the power of your thoughts. In his book 'The Biology of Belief', he wrote about our DNA being controlled by signals from outside the cell, including the energetic messages emanating from our positive and negative thoughts. He showed a link link between mind and matter, and the effects it has on us and our lives.
- Henry Ford -
Visualising connects you to your creativity ability within your mind. To clear the energy in a room, shut your eyes and'see' the space flooded with brilliant white light. White light transmutes any dense, negative energy into positive energy. I have found that this quick process can lighten the mood of a room and get energy flowing.
When preparing for a task, visualise how you would like the environment to feel to ensure the outcome you desire. Whether you're about to go on stage, walk into an interview, catchup with a friend in a cafe, undergo surgery, go house hunting, there is power in preparing the environment ahead of time. You have the power to set yourself up for success.
Believe it... do it... and you will have it.
Do you feel your ability to visualise lacks some clarity? To see how I can help, contact me at and book a free 30 minute discovery call.
In support of becoming the best you, you can be,

Farmers in Mato Grosso Have Sold 36.7% of 2021/22 Safrinha Corn
Author: Michael Cordonnier/Soybean & Corn Advisor, Inc.
Farmers in Mato Grosso had sold 92% of their 2020/21 corn as of the end of October according to the Mato Grosso Institute of Agricultural Economics (Imea). This represents an advance of 2.8% for the month of October. The average price during October was R$ 71.88 per sack (approximately $6.05 per bushel).
For the 2021/22 safrinha corn crop that farmers will plant in January and February, they have forward contracted 36.7% of their anticipated production as of the end of October. This represents an advance of 3.9% for the month of October. The average price during October was R$ 63.28 per sack (approximately $5.35 per bushel). Farmers are encouraged by the early soybean planting which should allow for early planting of the safrinha corn as well. The ideal planting window for safrinha corn in Mato Grosso usually closes about the third week of February.
Brazil's first corn crop is approximately 75% planted compared to 68% planted last year according to AgRural. Some of the earliest planted corn in the state of Parana is pollinating and starting to fill grain. In the municipality of Maringa, the corn is 31% pollinating, Francisco Beltrao is 8%, Ponta Grossa is 5%, Guarapuava is 2%, and Cascavel is 1%. The corn in Parana is rated 4% average and 96% good.

- A novel identification system for screening of the counterfeit drugs is proposed.
- The strategy provides an alternative.
- The strategy is demonstrated with high rapidity, accuracy and cost-effectiveness.
Quick inspection methods for counterfeit drugs are of vital necessity. In this study, the feasibility of portable Raman spectroscopy as an analytical method together with a novel identification system for fake drugs detection is demonstrated. The rapid and convenient identification system based on modified local straight-line screening (LSLS) and principal component analysis (PCA) is developed to distinguish counterfeit from authentic. LSLS algorithm was originally designed to detect synthetic drug(s) adulterated in herbal medicines based on infrared spectroscopy. In order to adapt the LSLS method for the detection of the suspected counterfeit drugs based on portable Raman spectroscopy, modification of weighting is made in this paper to obtain the low false positive rate (FPR) and low false negative rate (FNR). The proposed identification system has been benchmarked by 7 kinds (40 batches) of hypoglycemic tablets and 12 common pharmaceutical excipients. The total sensitivity, specificity and accuracy are 96.77%, 97.48% and 96.35% respectively. The results indicate that the identification system is appropriate for the on-site preliminary screening of the suspected counterfeit drugs.

By Rev. Jeremiah Cheung
The Church is a family. We fellowship with one another, but because of the ever-increasing number, we need to join small groups to have a real fellowship life. During the Lord Jesus' ministry on earth, thousands followed him. However, he chose 12 Apostles to live together with him. They were a small group.
The core value of fellowship with small group is 'sharing'. Acts 4:36 to 5:11 record two stories: the first is the story of Barnabas, the second is the story of a couple named Ananias and Sapphira. They sold everything they owned and gave the money from the sale to the Church, and they shared it with the brethren; however, one was true giving and the other false. Lt us learn from these examples the difference between true and false sharing.
1. Praise vs Flattery
2. Generous vs Greedy Sharing
3. Sharing to Give vs Sharing to Test God
4. True Sharing vs False Sharing


Using MsBuild tasks to build SSIS packages
In a previous blog post, I explained how to recompile the MsBuild task for SSIS 2016. Now that we've this task, we'll see how to use it.
First,let define a new file (here named Build.proj) in our SSIS solution
Then, we'll need to define our headers and namespaces:
The last attribute DefaultTargets is defining the part of the xml file that will be used when this file will be executed. In our case we'll just have one version of the Target but it's better to already correctly define it.
We also have to specify to MsBuild that an external assembly will be used (the community tasks to build SSIS packages).
It's now time to create a kind of variable to host the name/path of our SSIS project. Within MsBuild you achieve this task by using the following syntax:

SSISProjPath is the name of the variable and the value is defined in the Include attribute.
Now, let's focus on the Target itself. The target is named SSISBuild and will display a message before using the task to compile the SSIS project. The second step is performed by invoking the task DeploymentFileCompilerTask

The first parameter of DeploymentFileCompilerTask is the name of your project, you can safely use your variable by specifying the @() syntax. The second parameter is the configuration, personnaly I never change it and use Development but up-to-you. The protection level will override the corresponding property of your project.
If you want to compile, your project you can call MsBuild and specify Build.proj as the parameter, it will do the job! But it's more interesting if you can include this in your build steps. I'll just show you how you can include this in your TeamCity configuration:
 1. Create a build step
 2. Define the runner type as MsBuild
 3. Specify the MSBuild property for version as Microsoft Build Tools 2015 and ToolsVersion as 14.0
 4. Don't forget to specify the name of your target
 as SSISBuild
Once you've this setup in place, you can trigger your TeamCity project to get the following message and your build ready.

- parree (obsolete)
From earlier parree, from Middle English *parree, *paree, from Old French paree ("preparation, ceremony, parade"), from Medieval Latin parāta ("preparation, parade"), from Medieval Latin parāre ("to ward off, guard, defend, prepare, get ready"). More at pare. The English verb to parry is taken from the noun.
- To avoid, deflect, or ward off (an attack, a blow, an argument, etc.).
- 2011 September 28, Tom Rostance, "Arsenal 2 - 1 Olympiakos", in BBC Sport:
- Wojciech Szczesny was then called into action twice in a minute to parry fierce drives from Djebbour and Torossidis as Arsenal's back four looked all at sea.
parry (plural parries)
- A defensive or deflective action; an act of parrying.
- (fencing) A simple defensive action designed to deflect an attack, performed with the forte of the blade.
- (combat sports and martial arts) A defensive move intended to change the direction of an incoming strike to make it miss its intended target, rather than block and absorb it. Typically performed with an open hand in a downward or sideways slapping motion.

As part of the County of Ventura's ongoing commitment to addressing climate change impacts and enhancing wildlife habitat, the County launched a new Environmental Grant Program last November. Schools, nonprofits, and community organizations were asked to apply for up to $15,000 in funding to implement shovel-ready projects or activities that support wildlife habitat restoration, species conservation, environmental education and stewardship, and/or address climate change impacts.
The Environmental Grant Program's goal is to engage more people by reaching out and funding organizations that may not typically qualify or have difficulty competing for traditional grant programs. "We want to make sure that everyone has an opportunity to participate including children, people with diverse backgrounds and abilities and income levels because we all have a role to play in being good environmental stewards." said Linda Parks, former District 2 Board of Supervisor.
The County received 43 applications for project proposals located all over the Ventura Region and requesting funding from ~$300 to $15,000. Applicants ranged from grass roots community groups and high school environmental clubs to well-established local nonprofits environmental organizations. Majority of the applications focused on environmental education and habitat restoration projects that were committed to environmental diversity, equity, and inclusion, and removing barriers and providing access to underrepresented communities.
A Grant Selection Committee was formed with individuals from local non-profits and partner agencies to score and rank the applications based on ten criteria. This resulted in four applications being awarded funding from the new Grant Program. The funded applicants represent a grass roots collective advocating for open space and three nonprofits focused on conservation, watershed protection, and creating access watersheds and open space for underrepresented communities. Funding from the Grant Program should help some impacts felt by these organizations from the recent January storms that resulted in widespread damage across Ventura County, especially to the region's watersheds.
Since the County received so many exciting applications, it was very difficult to rank them. Thus, County staff are looking for additional sources of funding to potentially award a couple of smaller grants. County staff is also working to connect grant applicants with funding opportunities outside of the County's Environmental Grant Program. Lastly, through administering the Environmental Grant Program, County staff were able to learn about organizations that are doing important work to address climate change impacts and enhancing wildlife habitat. The Grant Program has helped the County connect with these organizations as well as introduce organizations that are doing similar work in hopes of creating future collaborations on project proposals.
The four Environmental Grant funded projects will have a year to complete their work. County staff looks forward to seeing their progress and learning more about each organization. For more information about the County of Ventura's sustainability efforts, please visit sustain.ventura.org.

Economic evaluation of snake antivenom production in the public system
Morais, V.Massaldi, H.
Snake antivenom, an expensive animal product, is presently the only effective treatment for the consequences of snakebite. In Latin America, antivenoms are mainly produced by public institutions with frequent shortages of the necessary supply. Here, we present an economical analysis of the factors affecting production cost, assuming a basic processing batch of 100 L hyperimmune plasma. Three annual production volumes were considered for two typical production technologies. The components of cost were classified as fixed, variable and semi-variable. We found that in all stages of production, fixed cost represents the major contribution to total cost, and is given essentially by manpower cost, particularly for low production volumes. Our estimation shows that antivenom cost can vary from US$ 2.4 to US$ 25 per 10 mL vial, depending on the production volume, the plasma processing technology used and the titer achieved during the immunization stage. We conclude that interested laboratories and authorities of countries with population at risk should consider the possibility of a joint production to improve the process efficiency, lower the product unitary cost and obtain the necessary supply for their own demand or that of other countries in need.Texto completo

Medical social work
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Britain and Ireland[edit]
Medical social workers in Britain and Ireland were previously known as Almoners, or Hospital Almoners. In Ireland, the origins of medical social workers go back to Dr. Ella Webb, who, in 1918, established a dispensary for sick children in the Adelaide Hospital in Dublin, and to Winifred Alcock, who trained as an Almoner and worked with Dr. Webb in her dispensary.[1]
In 1945, the Institute of Almoners in Britain was formed, which, in 1964, was renamed as the Institute of Medical Social Workers. The Institute was one of the founder organizations of the British Association of Social Workers, which was formed in 1970. In Britain, medical social workers were transferred from the National Health Service (NHS) into local authority Social Services Departments in 1974, and generally became known as hospital social workers.
United States[edit]
The Massachusetts General Hospital was the first American hospital to have professional social workers on site, in the early 1900s. The position was created by Richard Clarke Cabot to help patients to deal with areas of their life that made treatment difficult. This was important from an epidemiological point of view, as it made it easier to control and prevent outbreaks of syphilis and tuberculosis.[2]
The medical social worker profession[edit]
Role and required skills[edit]
Medical social workers play a critical role plan that will meet the patient's needs and allow the patient to leave the hospital in a timely manner. There are a number of factors that influence the timing of discharge; in private, community hospitals, it can be costly to allow patients to remain inpatient when it is no longer medically necessary. Discharge delays can prove costly to the hospital and to the patient depending on the patient's funding source.
For example, a medical provider informs the medical social worker that a patient will soon be "cleared for discharge" and will need in-home services. Depending on the setting, it may be the medical social worker's responsibility to arrange in-home services to coincide with the patient's discharge date. If the home care service is not in place at time of discharge, the patient may not be able to leave the hospital, resulting in a delay in discharge and the patient being placed on alternate level of care status (that is, deemed no longer requiring acute level of medical care, for which the hospital will receive a substantially lower rate of payment) until the necessary services are arranged.
Another skill required of medical social workers is the ability to work cooperatively with other members of the multidisciplinary treatment team who are directly involved in the patient's care. Medical social workers also need to have excellent analytical and assessment skills, an ability to communicate clearly with both patients and staff, and an ability to quickly and effectively establish a therapeutic relationship with patients. But of paramount importance, medical social workers must be willing to act as advocates for the patients, especially in situations where the medical social worker has identified problems that may compromise the discharge and put the patient at risk.
For example, a medical provider may report that a frail elderly patient, who lives alone, is medically stable for discharge and plans to discharge the patient home with in-home services. After assessing the patient's psychosocial needs, the medical social worker determines that the patient does not have the ability to manage at home safely even with the intervention of a home care worker. The medical social worker informs the medical provider that the proposed discharge plan may place the patient at risk and the discharge plan is deferred pending further assessment. The medical social worker can then collaborate with multidisciplinary providers to develop a more appropriate discharge plan even if that leads to discharge delays.
Medical social workers value the ethical concept of patient self-determination although this value can conflict with the values and ethics of other disciplines in a medical setting. Medical social workers strive to preserve the patient's right to make his or her own decisions about goals of care, treatment planning, discharge, etc. as long as the patient is capable of making those decisions him/herself. Patients often make decisions that medical professionals disagree with but the medical social worker advocates for the patient's right to self-determination. If the patient is not able to make his/her own decisions based on a cognitive or other impairment, the right of self-determination can be superseded by concern that a patient is a risk to self or others.
As medical social workers often have large case-loads and have to meet tight deadlines for arranging necessary services, medical social work is a demanding job. Medical social workers often deal with highly complex cases involving patients who come into the hospital with multiple psycho-social issues, all of which require assessment and treatment. It is not uncommon for medical social workers to treat cases involving homelessness, chronic unemployment, lack of income, lack of health insurance coverage, history of incarceration, and substance abuse problems. Any of these problems, separately and together, can impede timely discharge. Sometimes situations as seemingly mundane as the patient needing bus fare or a decent pair of shoes can lead to delays in discharge, especially if these needs are not identified quickly and early. This is why a complete and timely assessment of the patient's psychosocial needs is critical.

Lucius D. Clay, in full Lucius DuBignon Clay (born April 23, 1897, Marietta, Georgia, U.S.—died April 16, 1978, Cape Cod, Massachusetts) U.S. Army officer who became the first director of civilian affairs in defeated Germany after World War II.
Clay graduated from the U.S. Military Academy at West Point, New York (1918), and served in army engineer assignments before becoming head of the first national civil airport program (1940–41). Soon after the U.S. entrance into the war (December 1941), he became a leading production and supply specialist and was placed in charge of the army procurement program (1942–44).
In 1945 Clay was assigned by Pres. Franklin D. Roosevelt to be deputy military governor in Germany under Gen. Dwight D. Eisenhower. Two years later he was elevated to commander in chief of the U.S. forces in Europe and military governor of the U.S. Zone in Germany. During these demanding years, he had to gauge the requirements of food and shelter for a devastated civilian population and, simultaneously, supervise a de-Nazification and de-industrialization program that would harmonize with the postwar recovery of Germany's neighbours. In 1948–49 his administration was marked by the successful Allied airlift of food and supplies into Berlin during the Soviet blockade of that city.
Following his retirement in May 1949 Clay entered private business and became active in politics as a supporter and adviser of President Eisenhower (1953–61). In 1961 and 1962 Pres. John F. Kennedy asked Clay to serve as his personal representative in Berlin, with the rank of ambassador, to help deal with the critical situation that had developed among the four occupying powers concerning that city's future status.


is no longer needed for other nodes to send traffic to it. Instead, the NKN address is the only information needed to send packets to a node or client. The role of the NKN address in NKN is similar to an IP address in the Internet. Please refer to "NKN Address Scheme" section for how nodes and clients choose NKN addresses.
The distance from NKN addresses x to y is defined as
dist(x, y) = (y — x) mod 2^m
which satisfies the following conditions:
 - dist(x, y) >= 0
 - dist(x, y) = 0 if and only if x = y
 - dist(x, z) <= dist(x, y) + dist(y, z)
 - dist(x, y) = dist(x + a, y + a)
Note that the distance metric is asymmetric such that dist(x, y) (distance from x to y) is generally not equal to dist(y, x).
Some people may ask, why does NKN define a concept of "distance" in the network? In fact, this is because with the definition of "distance", you can define the topology of the network. The network topology is extremely important for NKN. E.g:
We first define the successor and predecessor node of any NKN address x
successor(x) = argmin_y {dist(x, y) | y in all nodes}
predecessor(x) = argmin_y {dist(y, x) | y in all nodes}
Successor and predecessor of a node can be defined similarly, except that the successor and predecessor of a node cannot be itself. If node x is the successor of node y, then y is the predecessor of x.
Each node x in NKN has a few neighbors:
successor((x + 2^i) mod 2^m), 0 <= i < m
{y | x is a successor of y}
Since not all NKN addresses are assigned to nodes, some neighbors above point to the same node. It is worth mentioning that neighbors are defined to be symmetric such that if y is a neighbor of x, x is also a neighbor of y. The expected number of neighbors of a node is O(log(N)).
Clients connect to the NKN through nodes. A client at NKN address x is connected to predecessor(x). The client sends and receives data only through established connections with the node it's connected to and thus no client public IP address is needed. Clients in the NKN are similar to keys in Chord DHT (except that it's connected to its predecessor rather than successor).
Although there are other topology that may lead to a more efficient routing path, our choice has a critical advantage such that each choice of neighbor can be verified by at least one other node. Suppose a node at address x should choose A as its i-th successor node. In this case, there are no nodes between address (x + 2^i) mod 2^m and A, and A should have known this information from its predecessor. Thus A knows that itself should be a neighbor of x. If node x does not choose A as a neighbor, A is able to falsify it. Similarly, if x chooses another node between A and (x + 2^(i+1)) mod 2^m in addition to A as neighbors, A should also be able to falsify it. Verifiability is crucial to an open network that may have a nontrivial portion of malicious nodes. It greatly reduces the possibility that malicious nodes choose specific neighbors to attack the system.
If you understand the principles of DDTN topology selection, then we can further introduce the DDTN routing technology. Given an established NKN network, routing can be achieved in a greedy algorithm using only information about neighbors. When a node wants to send or relay a packet to a destination address, it sends the packet to the neighbor that has the smallest distance to the destination address. The remaining distance becomes at most half of the previous value for each relay, thus decreases exponentially or faster as the packet is being relayed. Similar to Chord DHT, the expected number of hops is O(log(N)) given uniformly distributed addresses.
If the destination address is a client rather than a node, the above routing stops as long as the packet reaches the node connected to the client. The node then relays the packet to the client through the established connection.
The route between any two node pair is verifiable. Suppose a node sending a packet to destination address D should choose its neighbor A as the next hop while it actually chose neighbor B. From the routing rule we know that dist(A, D) < dist(B, D). Then A is able to falsify the route. If the node chose a non-neighbor node as the next hop, then such route can be falsified by the actual neighbor as discussed previously. The verifiability of routing is crucial to reduce the possibility of forming routes consisting of only malicious nodes. For a practical relay path validation algorithm, please refer to "Relay Path Validation" section.
In addition to network topology and routing, NKN must consider openness in order to build a network-based public blockchain. This requires a set of NKN protocols to define the behavior of the nodes/clients, such as node/client join, node/client exit, channel keepalive messages, network stabilization mechanisms, and so on.
Since NKN is an open network, it is inevitable that nodes will join and leave the network at any time, with or without prior notification. To efficiently maintain the NKN, each node locally maintains three lists:
 1. Its successors and predecessors. At least one successor and one predecessor is needed, while keeping more nodes in the list enhances fault tolerance. (For specific principles, please refer to the NKN White Paper Ising Model Mathematical Proof and Simulation Results: _URL_ ).
 2. Its neighbors.
 3. Clients connected to it.
Nodes update these lists in response to topology changes. For efficiency, it is important that when a node or client join or leave the network, only a small portion of the other nodes (up to O(logN)) are updates. We have the following protocols that satisfy our goal in dynamic environments.
Table 1 Overview of NKN Protocol Definition
Figure 4 NKN node-join protocol flow chart
Figure 5 NKN node-exit protocol flow chart
Proof of Relay (PoR)
One of the key problems in NKN is to prove how much data a node relayed, which we define as Proof of Relay (PoR). PoR is crucial to the NKN as the amount of data being relayed is directly related to token rewards. An ideal proof should satisfy the following conditions:
 1. verifiable: anyone, involved in data transmission or not, is able to verify the proof correctly using only public information;
 2. unforgeable: no party, unless controlled all involved nodes, is able to forge a valid proof with nontrivial probability;
 3. untamperable: no party, unless controlled all involved nodes, is able to modify a valid proof with nontrivial probability.
Unlike Bitcoin and Ethereum mining, PoR is a useful proof of work: mining the data samples under transmission in an active channel. NKN achieve this by using a particular chain of signature. To improve efficiency, we use the hash of the chain to randomly select proofs in an uncontrollable but verifiable way. Moreover, we select a class of proofs that is proven to be hard to forge even for a large malicious party that has controlled a significant portion of all nodes in the network to be eligible for other benefits such as mining rewards.
One of the primary functions of the NKN is to transmit data. To be transparent to higher level applications, NKN works with network packets. Packet originates from source which can be either node or client, then relayed by relayers which can only be nodes, and finally arrives at destination which can be either node or client. The basic transmission unit in NKN is the NKN packet. The fields of a NKN packet are shown in Table 2.
Table 2 Summary of NKN Packet Fields
As can be seen from Table 2, the signature chain is part of the NKN packet and is the part of the NKN packet that may be on chain. The signature chain is a signature chain that the relay node signs in turn when forwarding the NKN packet, as shown in Figure 6. Each element in the signature chain consists of the following fields: the NKN address and public key of the relay node, the NKN address of the next relay node, and the signature(signature of the previous element on chain, relayer NKN address, next relayer NKN address) signed with relayer private key.
Figure 6 Schematic diagram of the signature chain structure
As illustrated in Figure 6, the essential feature of a signature chain is its verifiability. A signature chain is valid if and only if for each element on chain, the following conditions are satisfied:
 - The relayer NKN address matches the next relayer NKN address of the previous element.
 - The signature field is valid.
Any modifications to a signed NKN packet except the payload will invalidate the signature chain unless re-signed. Thus, a signature chain is verifiable to anyone who has access to the NKN packet (no need for the payload). A malicious party cannot tamper with or forge a signature chain without having all the private keys along the route.
A NKN packet is valid if and only if the following conditions are satisfied:
 1. Payload

Halfway Home – The Rehabilitation of New Zealand Second World War POWs in Britain
While suffering through monotony and deprivations, New Zealand Second World War POWs mentally escaped their confines by imagining their eventual return home. They envisaged returning to a world free from the woes of captivity and war. This paper examines their rehabilitation in Britain. While Britain was not New Zealand, the prisoners expected it to conform to their idealised version of home. However, this paper argues prisoners experienced difficulties during their rehabilitation, and they were destabilised when confronted with the continued presence of the war and captivity.

UART-based connections
Renode allows connecting boards into a network using UART devices that exchange data.
Creating a hub
UART devices can be connected together using UART hubs.
To create a hub named uartHub, execute:
(monitor) emulation CreateUARTHub "uartHub"
Connecting UART devices
In order for UART devices to be able to communicate, they must be connected to a common UART hub.
Exactly as in the case of the wired network, use connector to connect them together:
(monitor) mach set 0
(machine-0) connector Connect sysbus.uart uartHub
(machine-1) mach set 1
(machine-1) connector Connect sysbus.uart uartHub
Disconnecting UART devices
You can also disonnect a device from a hub with:
(machine-1) connector Disconnect sysbus.uart uartHub
Running the simulation
The UART hub is created in a paused state, which means it won't transfer any data between devices. To enable the communication it must be started first. It happens automatically when starting the whole simulation, with:
(monitor) start
or can be triggered manually, with:
(monitor) uartHub Start
From this moment on data sent to sysbus.uart on machine-0 will be received by sysbus.uart on machine-1 and vice versa.
You can also stop a hub at any moment, with:
(monitor) uartHub Pause
In order to ensure the determinism of the simulation, bytes sent over an uartHub are buffered and delivered to the receiver at predefined times. Please, note that this might lead to slight delays in the communication. The maximum delay is controllable by the quantum parameter. For details on how the synchronization works and how to configure it, refer to the synchronization section of the documentation.


text: Non-discrimination is a recognized objective in algorithmic decision making. In this paper, we introduce a novel probabilistic formulation of data pre-processing for reducing discrimination. We propose a convex optimization for learning a data transformation with three goals: controlling discrimination, limiting distortion in individual data samples, and preserving utility. We characterize the impact of limited sample size in accomplishing this objective. Two instances of the proposed optimization are applied to datasets, including one on real-world criminal recidivism. Results show that discrimination can be greatly reduced at a small cost in classification accuracy.

In this paper, a novel design of biomass battery has been introduced for providing electricity to meet the lighting requirements of rural household using biomass. A biomass battery is designed, developed and tested using cow dung as the raw material. This is done via anaerobic digestion of the cow dung, and power generation driven by the ions produced henceforth. The voltage and power output is estimated for the proposed system. It is for the first time that such a high voltage is obtained from cow dung fed biomass battery. The output characteristics of this novel battery design have also been compared with the previously designed battery.
