G protein-coupled receptors play a critical role in atrial fibrillation (AF). Spexin is novel ligand of galanin (GALRs). In this study, we investigated the regulation spexin and GALRs on AF underlying mechanisms.
This paper presents the first orthogonal frequency-division multiplexing(OFDM)-based digital over-the-air computation (AirComp) system for wireless federated edge learning, where multiple devices transmit model data simultaneously using non-orthogonal OFDM subcarriers, and server aggregates directly from superimposed signal. Existing analog AirComp systems often assume perfect phase alignment via channel precoding utilize uncoded transmission aggregation. In contrast, our leverages...
This paper presents the first broadband digital over-the-air computation (AirComp) system for phase asynchronous OFDM-based federated edge learning systems. Existing analog AirComp systems often assume perfect alignment via channel precoding and utilize uncoded modulation model aggregation. In contrast, our leverages codes to overcome asynchrony, thereby achieving accurate aggregation in multi-user OFDM To realize a system, we propose non-orthogonal multiple access protocol that allows...
Gait, as one of unique biometric features, has the advantage being recognized from a long distance away, can be widely used in public security. Considering 3D pose estimation is more challenging than 2D practice , we research on using joints to recognize gait this paper, and new model-based recognition method JointsGait put forward extract information human body joints. Appearance-based algorithms are prevalent before. However, appearance features suffer external factors which cause drastic...
The casing leakage phenomenon seriously affects the safety and economic problems of oil gas production transportation. In this paper, numerical simulation study casing’s micro-leakage flow field acoustic is carried out by taking well as research object. CFD model established, influence size hole, shape pressure difference between inside outside on microleakage analyzed. An acoustic-vibroacoustic coupling calculation based Fluent LMS Virtual LAB sound value distribution at different...
Characterizing nonhomogeneous elastic property distribution of solids is great significance in various engineering fields. In this paper, we observe that the solution to inverse problem utilizing standard optimization-based approach sensitive sizes inclusions. The minimizes a cost function, containing absolute error between measured and computed displacements L2 norm. To address issue, propose novel scheme characterize shear modulus solids. method, function modified, dependent on size A...

The forms of tobacco-related crimes are changeable and highly concealed, resulting in a waste public security police resources. Tobacco-related images unstructured, high-dimensional, diverse. Therefore, this paper establishes database cases, implements target detection system for information. is divided into two parts: software algorithm. part realizes the transmission unformatted data, detects massive data on cloud server to complete end-to-end case tracking. In algorithm part, recognition...
