Purpose: The effects of the combination strength training and acupuncture on chronic ankle instability have not been studied. This study examined combined with balance ability, motion perception, muscle in among college students. Methods: Forty-six students were randomly categorized into experimental group (n = 24, + acupuncture) control 22, training) for an 8-week intervention. Results: For results at 8 weeks, compared baseline, group, Ankle Instability Tool (CAIT) score, dorsiflexion,...

Tungsten-doped vanadium dioxide (VO2) nanopowders were synthesized by thermolysis of (NH4)5[(VO)6(CO3)4(OH)9]·10H2O at low temperature with, to the best our knowledge, active white powdery tungstic acid (WPTA) used as a substitutional dopant for first time. The change in electrical resistance due semiconductor−metal transition was measured from −5 150 °C four-probe method. Differential scanning calorimetry and resistance−temperature curve indicated that phase VO2 powders 67.15 °C, but...

Objective This study aimed to investigate the effects of combined elastic band resistance training (EBRT) and whole-body vibration (WBVT) on lower limb isokinetic muscle strength, balance physical performance in older women with history falls. Methods A total 102 a falls was randomly assigned group ( n = 28), plus 28) control for 12-week program. All groups performed identical exercises (half squats, static left/right lunges) thrice weekly. The trained flat ground without bands or vibration;...

New fog seal material has been developed using emulsified asphalt (EA) modified by composite agents including waterborne epoxy resin (WER), polyurethane (WPU), acrylic (WAR) or cement, to address the shortcomings of conventional in terms poor durability and adhesion. Test results showed that new was uniformly dispersed stable store, with improved pullout strength 2-4 times, a water permeability coefficient close zero slight reduction British Pendulum Number when comparing without fine sand....

Abstract We study the Schwinger correlation of Dirac fields in noninertial frames under influences both constant and pulsed electric fields. use entanglement negativity quantum mutual information between particle antiparticle as indicator observed by accelerated observers. find that inertial is largest. With increase acceleration observers, becomes smaller smaller, but does not vanish limit infinite acceleration. For given acceleration, a nonmonotonic function field intensity, there an...

In the past, almost all slurry tubular photocatalytic reactors were working in a continuous and circulating mode. Herein, we reported new mode with intermittent stop of reaction flow for enhanced hydrogen production using facilely designed channel reactor. The optimal rate light intensity also investigated to obtain highest production. We found, first time, that there is an residence exposure time fluid which leads much higher than manner. such mode, pump work can be significantly saved....

Camouflage spots are mostly color patches of different colors. Compared with the traditional empirical matching method, computer can quickly and effectively calculate proportion red, yellow, blue primary In general, camouflage in practical application initial formula is not accurate multiple modification still cannot match. First, we measured chroma coordinates 98 standard swatches made green, coatings proportions by OHSP-660 spectral reflectance tester. Then, adopted polynomial regression...

W215 vital sign detection is a promising technique, which allow users to non-invasively detect the respiration of target through capturing variation wireless signals. In particular, using received signal strength (RSS) has gained more attention since RSS available in most commercial off-the-shelf (COTS) products, can remarkably reduce cost system. However, resolution measurement provided by those equipment usually larger than 0.1dB, unable perform reliable detection, especially when chest...

In non-commutative spaces the invariant eigen-operator method is used to derive and calculate Hamiltonian spectra for three kinds of coupled harmonic oscillators: no coupling, coordinate coupling momentum coupling. According comparison with results in commutative space, it shown that when parameter zero obtained energy levels are equal space. Finally effect coefficient on spectrum space discussed.

Correlation between road sections has a strong practical significance in traffic raw data repair, precision control and prediction. In this paper, the co-integration theory of econometrics is applied to correlation analysis flow parameters series based on loop detection Shanghai expressway. Then we establish repair model according plane geometry types road, sections. Experimental instances show that compared with traditional approaches, method can reduce error good prospect.

The design of the system in this paper is based on ARM and FPGA platform, we use two CMOS cameras, collect image data directions (X direction Y direction) vertically optical fiber, so can obtain three-dimensional fiber welding image. cameras processed by ARM, displayed parallel display device. new improve speed acquisition fusion

It is an important factor for affecting camouflage effects, but copying background color with empirical matching has poor accuracy. This paper chose cadmium red, yellow and other colors basing on the performance requirements of same-color same-spectrum; prepared pastes swatches different grinding times particle sizes, were to measure their spectral reflection characteristics; then selected cobalt blue as base pigments, which are roughly same natural background-green in infrared band...

This For the purpose of avoiding high expense and time-consuming caused by resolution radar imaging system, a image modulation method is put forward in this paper, which based on properties target microwave properties. Optic same used first to locate classify target, then statistic characteristics estimate average brightness fluctuation image. Finally, proper point spread function modulate mistiness Possible use also discussed.

For the purpose of describing microwave properties absorbing ceramics, usability effective-medium theory for this kind materials was investigated. Different equations deduced from were first discussed and then compared with measured data sample. It found that could not explain well only if some empirical exponent used.
