Understanding sap flow is crucial for comprehending tree growth. However, it impractical all farms to directly measure flow. Although many studies have attempted predict flow, most of them relied on hard-to-obtain data in addition weather information. This study aims propose a model predicting ‘Shingo’ pear trees using only easily accessible variables, civil twilight time, and DAFB (Days After Full Bloom). Additionally, account the time-lag effect nonlinear relationship between we performed...
In this study, a compact smart-sensor tag is developed for estimating pork freshness. The smart sensor can be placed in areas where packaged meat stored or displayed. Antennas and simulated models were to maximize the efficiency of radio frequency (RF) energy harvesting. proposed includes red, green, blue that detects changes freshness meat.

Lymphedema is a global health problem with no effective drug treatment. Enhanced T-cell immunity and abnormal lymphatic endothelial cell (LEC) signaling are promising therapeutic targets for this condition. Sphingosine-1-phosphate (S1P) mediates key pathway required normal LEC function, altered S1P in LECs could lead to disease pathogenic activation. Characterizing biology relevant developing much needed therapies.
Pathologic lymphatic remodeling in lymphedema evolves during periods of tissue inflammation and hypoxia through poorly defined processes. In human mouse lymphedema, there is a significant increase inducible factor 1 α (HIF-1α), but reduction HIF-2α protein expression endothelial cells (LECs). We questioned whether dysregulated these transcription factors contributes to disease pathogenesis found that LEC-specific deletion Hif2α exacerbated pathology. Even without vascular injury, the loss...
This study proposes a self-powered food monitoring system that benefits from far-field RF Energy harvesting and deep learning techniques. Recent smart IoT systems for quality management mainly focused on the appearance of Total Volatile Organic Compounds (TVOCs) during preservation, which has limitations large power consumption, complex configuration, low accuracy. Different these methods, we aim to measure gradual increase in air pressure inside packages caused by gas emissions...

At present, the identified plant are composed 62 145 total since their first appearance reported. found roadside 46.7%, followed by forests 33.3% orchard 20%. Nymphs adults cause damage crop sucking juice, outbreak fungi through secretion...
This study focuses on minimizing fuel consumption of a cell hybrid tram, operated with electric power from both the stack and energy storage system, by optimizing distribution between distinct sources. In field system application, dealing real-world optimal control implementation becomes more important. Some ‘online control’ strategies optimize management measuring current battery’s state planning for future cycles. However, its dependence stochastic processes remains limitation adapting...
A new tactile sensing module was proposed to sense the contact force and location of an object on a robot hand, which attached finger. Three air pressure sensors are installed at tip finger detect contacting points. To obtain nominal from data three sensors, estimation developed based upon learning deep neural network. The were utilized as inputs estimate In module, arrival time sensor has been recognize point against object. Using time, can be divided into 3 × block locations. resolution...
Automated monitoring technology is necessary to ensure the safe consumption and management of meat. Here we propose a system for determining food freshness on basis data collected by embedded cameras gas sensors using artificial intelligence things (AIoT). Using DeepLab V3+ model, images meat obtained from underwent semantic segmentation into lean fat, revealing nature rotting over time. convolutional neural network (CNN) learning, classified fresh, semi-fresh, rotten detected transition...
본 연구는 유통 농산물의 잔류 실태를 조사하여 잔류농약에 대한 안전성을 평가하기 위해 수행되었다. 전국 9개 지역에서 수거된 농산물 15개 품목 232건을 식품공전 다종농약다성분 분석법으로 분석하였으며, GC/MSMS로 분석 가능한 농약 196종을 대상으로 하였다. 그 결과 53건의 시료에서 64종의 농약이 검출되었고 이 중 chlorpyrifos와 procymidone이 가장 빈번히 검출되었다. 검출된 64종 깻잎에서 복숭아에서 picoxystrobin은 잔류허용기준을 초과하였으며, 나머지는 각각의 초과하지 않았다. 초과한 picoxystrobin을 포함한 검출 농약에 대해 위해평가를 수행한 결과, 1일 섭취허용량(acceptable daily intake, ADI) 대비 추정섭취량(estimated EDI)이 0.001~0.902%로 조사되어 매우 낮은 수준임을 확인할 수 있었다. 이번 연구 농산물에서 잔류농약은 안전하게 관리되고 있음을 확인 할 있었고, 향후 식품안전...
Abstract With the rapid growth of e‐commerce market facilitated, users are often overwhelmed by excessive online information, making item selection challenging. While recommendation services have significantly enhanced user experience and sales, these traditional models overlook complexity user‐item interactions preferences based on various aspects. The proposed AXCF framework innovatively combines graph‐based collaborative filtering (CF), which captures high‐order connectivity between...
