Polyvinyl alcohol (PVA) hydrogels have been proposed for use as promising biomaterials in biomedical and tissue engineering but their poor mechanical water-retention properties hindered development. Graphene oxide (GO), an excellent nanofiller, was added to PVA make GO/PVA composite by a freeze/thaw method. The of the were significantly improved. Compared pure hydrogels, 132% increase tensile strength 36% improvement compressive achieved with addition 0.8 wt% GO, which suggests load transfer...
Occluded person re-identification (re-id) aims to match occluded images holistic ones. Most existing works focus on matching collective-visible body parts by discarding the parts. However, only preserving causes great semantic loss for images, decreasing confidence of feature matching. On other hand, we observe that can provide missing information same identity. Thus, compensating image with its counterpart has potential alleviating above limitation. In this paper, propose a novel Reasoning...
Background Plasma membrane tension-related genes (MTRGs) are known to play a crucial role in tumor progression by influencing cell migration and adhesion. However, their specific mechanisms bladder cancer (BLCA) remain unclear. Methods Transcriptomic, clinical mutation data from BLCA patients were collected The Cancer Genome Atlas (TCGA) Gene Expression Omnibus (GEO) databases. Clusters associated with MTRGs identified consensus unsupervised cluster analysis. of different clusters analyzed...
Human-in-the-loop optimization (HILO) has been used to identify subject-specific assistive strategies and improve the performance of wearable exoskeletons. However, there is still a gap in research on HILO regarding knee exoskeleton flexion assistance. We present methodology that optimizes torque delivered by exoskeleton. The cooperation mechanism flexor antagonist muscles assisted first analyzed through dynamic model. Furthermore, online rapid metabolic evaluation function, including...
Polymers with both high refractive index and excellent transmittance are in demand for use optoelectronic devices. Polyarylates regarded as one of the most promising categories optical materials. However, there higher requirements polyarylates terms refraction a degree light reansmission.In this study, series novel were designed synthesized by nucleophilic reaction using bisphenol pendant cardo structure acid chloride from bio-based diacid (2,5-thiophenedicarboxylic acid). These displayed...
A reconfigurable injection-locked local oscillator (RE-ILO) generator that leverages a multitanks wideband-harmonic-shaping Class-F23 voltage-controlled (VCO), RE frequency multiplier (RE-ILFM), and power-efficient amplifier (ILFA) for multiple fifth-generation (5G) millimeter-wave (mm-wave) bands is hereby presented. For the VCO, an inductive inside positive feedback loop boosts drain-to-gate voltage gain (Av). Besides, source-inductive loaded on output buffer, coupled with separated...
The Least Squares Residual (LSR) algorithm, one of the classical Receiver Autonomous Integrity Monitoring (RAIM) algorithms for Global Navigation Satellite System (GNSS), presents a high Missed Detection Risk (MDR) large-slope faulty satellite and False Alarm (FAR) small-slope satellite. From theoretical analysis MDR FAR cause, optimal slope is determined, thereby test statistic fault detection conceived, which can minimize with not exceeding its allowable value. To construct approximate to...
Food image recognition is a key enabler for many smart home applications such as kitchen and personal nutrition log. In order to improve living experience life quality, systems collect valuable insights of users’ preferences, intake health conditions via accurate robust food recognition. addition, efficiency also major concern since are deployed on mobile devices where high-end GPUs not available. this paper, we investigate compact efficient methods, namely low-level mid-level approaches....
Ground‐based augmentation systems (GBASs) are widely used using satellite navigation. GBAS can improve the performance of BeiDou navigation system (BDS) in civil aviation application. Evaluation is necessary before a GBAS. On basis flight trials conducted at Dongying airport, evaluation results show that based on both global positioning (GPS) L1 signal and BDS B1I signal, ground accuracy designators (GADs) four reference receivers consistent with GAD‐C levels. The improvement obtained...
In this study, an approach based on precise point positioning (PPP) is proposed for the assessment of global ionospheric maps (GIMs). This performed by comparing GIMs with vertical total electron content (VTEC) values retrieved using PPP technique. The results indicate that CODG, ESAG, WHUG, and CASG products underestimate VTEC values. There a high level consistency between all PPP-VTEC during periods low solar activity. addition, almost exhibit significant discrepancies over equatorial...
To ensure the integrity of a ground-based augmentation system (GBAS), an ionosphere-free (Ifree) filtering algorithm with dual-frequency measurements is employed to make GBAS free first-order ionospheric influence. However, Ifree outputs errors two frequencies. The protection level obtained via traditional Gaussian overbound overconservative. This conservatism may cause false alarms and diminish availability. An overbounding framework based on mixture model (GMM) proposed handle samples...
