Chronic low back pain (CLBP) is a common and refractory musculoskeletal disease, which seriously affects patients' work life. Electroacupuncture (EA) has become popular method for the treatment of CLBP due to its advantages high safety few side effects, but effect still controversial. One important reasons that individual differences make EA therapy not effective everyone. Through machine learning method, therapeutic prediction model was constructed from surface electromyography (sEMG) data...

Frankliniella intonsa (Thysanoptera: Thripidae) is a polyphagous pest that causes significant economic agricultural losses by damaging flowers, vegetables, and fruit trees. We performed an age-stage two-sex life table analysis to evaluate the performance adaptability of F. against nine common vegetable crops cultivated in Guangxi: cowpea (Vigna unguiculata) (Fabales: Leguminosae), green beans (Phaseolus vulgaris) soybean (Glycine max) catjang cylindrica) courgette (Cucurbita pepo)...

The key technologies for applying fifth generation in high-altitude platform station (HAPS) communication systems have many outstanding advantages, especially large-scale antenna array technology. HAPS inherent advantages that can perfectly complement technology and solve the problems of existing ground systems. chances long-packet data users short-packet being serviced are different due to differing length each user's packet. According channel environment length, user with smallest delay is...

Channel allocation is the prerequisite for HAPS (high-altitude platform station) 5G communication network to transmit information. An intelligent wireless channel algorithm massive MIMO (multiple-input multiple-output) system based on reinforcement learning was proposed. Q-learning and back-propagation neural were combined, which enabled systems autonomous learn according environment allocate resources of efficiently. Agents perceive state information in through continuous interaction with...

Facial muscle activities are essential for the appearance and communication of human beings. Therefore, exploring activation patterns facial muscles can help understand neuromuscular disorders such as Bell’s palsy. Given irregular shape well their different locations, it should be difficult to detect whole with a few electrodes. In this study, high-density surface electromyogram (HD sEMG) system 90 electrodes was used record EMG signals in both healthy palsy subjects when they did movements....

The crosstalk severely affects the viewing experience for auto-stereoscopic 3D displays based on frontal projection lenticular sheet. To suppress unclear stereo vision and ghosts are observed in marginal zones(MVZs), aberration of sheet combining with projector is analyzed designed. Theoretical experimental results show that increasing radius curvature (ROC) or decreasing aperture can reduce crosstalk. A array 20 micro-projectors used to frontally project parallax images one ROC 10 mm size...

Megalurothrips usitatus (Bagnall) feeds on the young tissues of plants, causing wilting and deformity leaves as well damage to flowers fruits, thereby seriously affecting plant yield. Due its small size difficulty control, species is one most important pests in legume family. To clarify occurrence pattern M. field crops, a study was conducted using eight different crops experimental materials, an age-stage, two-sex life table constructed. The population density highest cowpeas (Vigna...

The intensity of electrical acupoint stimulation such as electroacupuncture (EA) and transcutaneous nerve (TENS) is regulated by the observation skin shivering or participant's comfort response. However, specific spatial scope following EA TENS are unclear.This study aimed to test stimulatory current intensities lower upper sensation thresholds in TENS- EA-based treatment Bell's palsy patients. Also, at these was simulated measured quantitatively.A total 19 patients were recruited. Six...

Reconstruction the computer generated Fresnel hologram of complex 3D object based on compressive sensing (CS) is presented.The synthesized from a color image and depth map object.With map, intensity can be divided into multiple slices, which satisfy condition sparsity CS.Thus, reconstructed at different distances with corresponding scene focused using CS method.The quality recovered images greatly improved compared that back-propagation method.What's more, sub-sampled hologram, ideally by...

Aiming at the problems of sparse features, polysemy one word and less context related information in short text automatic scoring, a scoring model based on bidirectional encoder representations from transformers - long short-term memory (BERT-BiLSTM) is proposed. Firstly, large-scale corpus pre-trained with (BERT) language to acquire semantic features general language. Then semantics keywords specific are acquired through data for pre-fine tuning downstream tasks set pre-fined by BERT. And...

Mobile self-organizing networks, such as vehicular ad-hoc network (VANET), in most cases rely on infrastructure deployment to provide access internet services and other resource. Therefore, it is crucial optimize the of roadside units (RSUs) vehicle network. In this paper, we propose a RSU optimized scheme based large data, which considers cost latency performance synthetically. We deploy problem multiobjective optimization for mathematical modeling. On basis, two-step solution proposed:...

BACKGROUND: Chronic lower back pain (CLBP) is one of the most common disorders worldwide. Flash cupping has ability to relieve CLBP; nevertheless, its impact on CLBP and likely mechanism action have not been studied. OBJECTIVE: The goal this study was assess a single, brief session low muscle activity using multichannel surface electromyography (sEMG).

This paper presents a novel framework for continual feature selection (CFS) in data preprocessing, particularly the context of an open and dynamic environment where unknown classes may emerge. CFS encounters two primary challenges: discovery knowledge transfer known knowledge. To this end, proposed method combines strengths learning (CL) with granular-ball computing (GBC), which focuses on constructing base to detect facilitate previously learned further selection. consists stages: initial...
