Animals navigate environments with multiple objects to find rewards. We previously found that phasic activities of lateral habenula (LHb) neurons encode step-by-step changes in reward predictions induced by the series and errors. However, obtain reward, another important source would be maintain their mind at beginning tolerate capricious errors following steps continue sequence actions. periaqueductal gray (PAG) neurons, LHb downstream brain area, transport expectation from one step next...

To improve the initiation and speed of intended action, one crucial mechanisms is suppressing unwanted movements that interfere with goal-directed behavior, which observed relatively aberrant in Parkinson's disease patients. Recent research has highlighted dopamine deficits predominantly occur caudal lateral part substantia nigra pars compacta (SNc) human We previously found two parallel circuits within basal ganglia, primarily divided into mediated by rostral medial SNc neurons. have...
Sketching continues to be a vital part of methods and technologies related Concept Development, including those analyzed in this paper: "concept design with constraints", "solid from sketch", "sketching on point cloud" "geometric modeling constraints".Existing are critical subproblems identified.New solution proposed for the subjects sketch" cloud".
In real life, multiple objects of different values are mixed in a variety environments. To survive, animals need to find rewarding that may be located but hidden particular contexts (e.g., environments) with bad unassociated reward. Then, and humans pay attention the enriched environment so they can object vigorously. How brain initiate such behavior based on context? We thus created behavioral task for monkeys which contextual events (environment, action cue) sequentially occurred before...
For many animals, social interaction may have intrinsic reward value over and above its utility as a means to the desired end. Eye contact is starting point of interactions in including primates, abnormal patterns eye are present mental disorders. Whereas abundant previous studies shown that negative emotions such fear strongly affect behavior, modulation by has received scant attention. Here we recorded movement neural activity lateral habenula while monkeys viewed faces context Pavlovian...
A solution process to obtain a thin film of organic semiconductors allows for the fabrication low-cost electronic devices without using expensive vacuum equipment. Thus, development an efficient method deposit large area and patterned films via is great importance. Among various deposition methods, electrospray promising candidate that can be employed in industrial field as alternative spin coating. In this study, we fabricated poly(3-hexylthiophene-2,5-diyl) (P3HT) while varying parameters....
Predicting future international events from textual information, such as news articles, has tremendous potential for applications in global policy, strategic decision-making, and geopolitics. However, existing datasets available this task are often limited quality, hindering the progress of related research. In paper, we introduce WORLDREP (WORLD Relationship Event Prediction), a novel dataset designed to address these limitations by leveraging advanced reasoning capabilities large-language...
Abstract Disappointment is a vital factor in the learning and adjustment of strategies reward-seeking behaviors. It helps them conserve energy environments where rewards are scarce, while also increasing their chances maximizing by prompting to escape richer anticipated (e.g., migration). However, another key obtaining reward ability monitor remaining possibilities outcome tolerate disappointment order continue with subsequent actions. The periaqueductal gray (PAG) has been reported as one...
호텔객실 매출액에 대한 과학적인 예측은 호텔의 효율적 관리를 위해 유용한 정보를 제공하며, 호텔관리에 대해 중요한 영향을 미친다. 본 연구는 호텔 매출 데이터의 시계열 분석을 통해서 향후 매출액을 예측하고자 한다.본 연구 목적을 달성하기 위해서 계절별 자기회귀 통합이동평균 모형(Seasonal ARIMA)을 적용하였으며, 계절 ARIMA 모형의 데이터는 2020년 1월 5일부터 2022년 10월 23일까지 부산의 4 성급 데이터를 기반으로 하였다. 사례 대상 객실 매출액 계절성은 지수를 계산하고 시계열에 모델을 적용하여 모델링하고 예측을 진행하였다. 결과와 관련하여, Seasonal ARIMA(2, 1, 3)(1, 1)[12] 모델은 사례대상 예측할 때 최적의 성능을 제공해서 최종적으로 이 모형을 선택하였다. 모델 선택 및 예측 정확도에 프로세스는 연구에서 자세한 설명이 제시된다.본 연구의 결과는 사용된 방법이 MAPE(평균절대오차 백분율)을 확인한 후에 평균 오차율이 0%≤...
This study aims to forecast the size of market considered for seasonality based on past demand data and present a prediction model whale ocean travel ships tourism in Ulsan, Korea. For this, this collected from January 2010 December 2020 Tourism Knowledge & Information System. In order achieve research purpose, time series analysis Seasonal ARIMA which is widely used econometrics was conducted. We intend compare predictions observations obtained using ARIMA, that is, autoregressive moving...
