One of the most exciting future applications terahertz technology is in area wireless communications. As 5G systems incorporating a standard for millimeter-wave links approach commercial roll-out, it becoming clear that even this new infrastructure will not be sufficient to keep pace with rapidly increasing global demand bandwidth. favorable solution attracting attention subsequent generations use higher frequencies, above 100 GHz. The implementation such require significant advances...
Abstract The development of components for terahertz wireless communications networks has become an active and growing research field. However, in most cases these have been studied using a continuous or broadband-pulsed source, not modulated data stream. This limitation may mask important aspects the performance device realistic system configuration. We report characterization one such device, frequency multiplexer, at rates up to 10 gigabits per second. also demonstrate simultaneous...
Abstract Age is an important predictor of neuromuscular recovery after peripheral nerve injury. Insulin‐like growth factor 1 (IGF‐1) a potent neurotrophic that known to decline with increasing age. The purpose this study was determine if locally delivered IGF‐1 would improve regeneration and in aged animals. Young rats underwent transection repair either saline or continuously the site repair. After 3 months, junction morphology were assessed. In both young animals, significantly improved...
We describe measurements of the diffuse bistatic scattering a modulated terahertz beam incident on five metallic rough surfaces, to investigate implications surface roughness for non-line-of-sight (NLOS) wireless data links at frequencies and above 100 GHz. The were performed using transmitter receiver modules, operating several from 400 dependence patterns parameters, including rms height correlation length. results are consistent with numerical models surface. They support design methods...
The terahertz band offers promising opportunities for high-capacity wireless communications but faces significant challenges from vegetation-induced channel impairments. This article presents a comprehensive investigation of THz propagation through vegetation, introducing hybrid modeling approach that combines deterministic vegetation dependent exponential decay with statistical characterization temporal variations. Through extensive laboratory measurements using Epipremnum aureum, we find...
Cation exchange capacity (CEC) reflects the ability of soil to sequester exchangeable cations and is an important indicator fertility environmental quality agricultural soils. The indoor titration method for determining cation expensive cumbersome. To this end, 565 samples from 0-20 cm plough layer were collected farmland in Ningxia, parameters pH, organic carbon, mechanical composition determined. A field-scale estimation model was constructed using multiple linear regression machine...
The smooth discharge of engine exhaust gas is important in accurately simulating aircraft laboratory climate test environments. In this study, a three-dimensional transonic ejector model developed by considering the phenomenon supersonic airflow fluctuation, theory ejection, and choking effect. Compressible numerical solution used to calculate overall performance internal flow ejector, effects geometrical operational parameters are analyzed reveal mechanisms choke laboratory. Finally,...
Botulinum toxin A (BoNT-A) is a potent biological widely used for the management of skeletal muscle spasticity or dynamic joint contracture. Intramuscular injection BoNT-A causes denervation, paresis, and atrophy. This clinical effect botulinum lasts 3 to 6 months, injected eventually regains mass recovers function. The goal present study was characterize molecular cellular mechanisms leading neuromuscular junction (NMJ) regeneration functional recovery after injection. Fifty-six 1-month-old...
Abstract Many applications of terahertz (THz) technology require the ability to actively manipulate a free space THz beam. Yet, although there have been many reports on development devices for signal processing, few these include possibility electrical control functionality, and novel ideas are needed active reconfigurable devices. Here, we introduce new approach, based integration electrically actuated liquid metal components in waveguides. This versatile platform offers possibilities...
Wireless communication at terahertz (THz) frequencies is viewed as one of the potentials for future 6G wireless systems. However, path secure data transmission by THz links facing many complex challenges. Of that, scattering-induced eavesdropping threat remains most critical but less explored. With updating carrier frequency into range, wavelength becomes comparable to surface roughness typical objects in our daily life. Surface scattering, which negligible current networks, serious and...

Neuromuscular junction destabilization following nerve injury contributes to irreversible functional impairment. Myogenic Regulatory Factors (MRF's) including myoblast determination factor (MyoD), MRF-4, Myogenin, and myogenic factors-5 (myf-5), Growth-associated protein 43 KDa (GAP43) regulate gene expression of nicotinic acetylcholine receptor (nAChR) subunits (alpha, beta, delta, gamma, epsilon). We hypothesized that induces altered MRF's, nAChRs, GAP-43 in the skeletal muscle which...
