The thermal band of a satellite platform enables the measurement land surface temperature (LST), which captures spatial-temporal distribution energy exchange between Earth and atmosphere. LST plays critical role in simulation models, enhancing our understanding physical biochemical processes nature. However, limitations swath width orbit altitude prevent single sensor from providing data with both high spatial temporal resolution. To tackle this challenge, unmixing-based spatiotemporal...

In recent years a number of research efforts have focused on effective use P2P-based systems in providing large scale video streaming services. particular, live and Video-on-Demand (VoD) attracted much interest. While previous mainly the common challenges faced by both types applications, there are still fundamental open questions designing VoD systems, which is focus our effort. Specifically, this paper, we consider BitTorrent-like system following questions: (1) how lack load balance,...

Forests of California are undergoing large-scale disturbances from wildfire and tree mortality, caused by frequent droughts, insect infestations, human activities. Mapping monitoring the structure these forests at high spatial resolution provides necessary data to better manage forest health, mitigate risks, improve carbon sequestration. Here, we use LiDAR measurements top canopy height metric (RH98) NASA’s Global Ecosystem Dynamics Investigation (GEDI) mission map vegetation across entire...

In the task of haze scene restoration, dark channel prior is most convincing theory. Its biggest contribution to introduce concept map, which convenient for acquiring initial transmission. Minimum filter basic operation map. Nevertheless, disadvantage minimum cause edge information jump, further brings Halo effect. Besides, invalid highlight areas such as white objects, and it also causes distortion. this letter, we design a delicate function replace operation, its purpose fundamentally...

BitTorrent (BT) has become an extremely popular and successful peer-to-peer (P2P) file sharing system. Although empirical evidence suggests that most nodes participate in multiple torrents, surprisingly little research literature exists on this topic. In paper we focus a multi-torrent system specifically the questions of (a) what incentives could be provided for to contribute resources as seeds environment, (b) are resulting performance consequences such behavior, both which willing overall...

Insufficient invasion of trophoblast cells is one the important causes preeclampsia (PE). Circular RNA (circRNA) has been proven to regulate biological functions and mediate progression PE. The expression circ_0085296, microRNA (miR)-942-5p, thrombospondin 2 (THBS2) was detected by quantitative real-time PCR. In addition, interaction between miR-942-5p circ_0085296 or THBS2 confirmed dual-luciferase reporter assay RIP assay. Our data showed that upregulated in placental tissues PE patients....

Severe color casts, low contrast and blurriness of underwater images caused by light absorption scattering result in a difficult task for exploring environments. Different from most previous image enhancement methods that compute attenuation along object-camera path through hazy formation model, we propose novel jointly wavelength compensation dehazing network (JWCDN) takes into account the surface-object simultaneously. By embedding simplified model generative adversarial network, can...

The dual-pixel (DP) sensor captures a two-view image pair in single snapshot by splitting each pixel half. disparity occurs defocus blurred regions between the two views of DP pair, while in-focus sharp have zero disparity. This motivates us to propose K3DN framework for deblurring, and it has three modules: i) disparity-aware deblur module. It estimates feature map, which is used query trainable kernel set estimate blur that best describes spatially-varying blur. constrained be symmetrical...

Acute exposure to hydrogen sulfide (H2S) can cause fatal acute lung injury (ALI). However, the mechanisms of H2S-induced ALI are still not fully understood. This study aims investigate role tight junction protein claudin-5 in ALI. In our study, Sprague-Dawley (SD) rats were exposed H2S establish model, and parallel, human pulmonary microvascular endothelial cells (HPMECs) incubated with NaHS (a donor) a cell model. Lung immunohistochemistry electron microscopy assays used identify ALI,...

Memory-based collaborative filtering algorithms have been widely adopted in many popular recommender systems, however the rating data are very sparse, which affects prediction accuracy greatly. To solve this problem, we use expert opinions to improve accuracy. Firstly, propose a novel similarity measure order highlight users' background. Then, combining ratings with opinions, get right balance both professional and similar users. Finally, since SVD-based shows good performance on prevention...

In the horizontal semiconductor business mode, foundry can tamper or overbuild integrated circuits (ICs) while owner of IC knows nothing about it. metering technique has been proposed to solve this problem. paper, we propose a new external active method. The physical unclonable function (PUF) is used generate unique key for each chip. We first modify finite state machine (FSM) so that PUF-based be securely retrieved from FSM. With regards overhead and security, retrieval scheme takes...

Aiming at the problem that traditional prior information‐based defogging algorithm fails in some special scenarios, an end‐to‐end convolutional network based on attention mechanism is proposed. The consists of two modules: parameter estimation and image restoration. First, multi‐scale convolution used to extract feature information. Residual skip connection methods are improve utilisation rate shallow Secondly, channel domain add weight input from previous select useful Finally, atmospheric...

This study aims to construct a new staging system for colorectal cancer (CRC) based on the lymph node ratio (LNR) as supplement American Joint Committee Cancer (AJCC) tumor metastasis (TNM) predicting prognosis of CRC patients with <12 nodes.The data 26,695 nodes were extracted from Surveillance, Epidemiology, and End Results (SEER) database training set. A total 635 also enrolled Northern Jiangsu People's Hospital affiliated Yangzhou University an independent validation Classification...
