Salt restriction, the method which was acknowledged by modern medical knowledge that could delay kidney disease progression, was advanced in ancient times. We found that salt restriction therapies were presented in many ancient literatures during our ancient literature mining work. We sorted out the ancient trace of salt restriction about edema in chronic kidney disease (CKD). From frequency of herbals,...
We experimentally demonstrate amplitude modulators (AMs) with >65 dB extinction across over a 160 nm spectral range. The output optical phase response is also characterized when the amplitude is modulated.
We experimentally realize an ultrafast tunable metasurface consisting of subwave-length gallium arsenide nanoparticles supporting Mie-type resonances, which are all-optically tuned by 30 nm in spectral domain under pump fluences as low as < 400 μJ/cm2.
The U-V or V-V winding connections of two single-phase distribution transformers are widely utilized in distribution systems to deliver power to various three-phase and/or single-phase loads. Such special winding connections of distribution transformers can cause three-phase voltage unbalance in distributions systems, which could also lead to unexpected trip of ground relay, extra power losses on...
In this paper a high order temperature compensation current reference circuit was proposed, which is accomplished by two current source with opposite temperature coefficients (TC) to obtain a smaller TC. The proposed circuit with a simple structure designed in Global Foundries 0.18μm CMOS process, achieving a temperature coefficient of 30.7ppm/°C in the range of −50∼120°C, and the quiescent current...
Due to the test requirements of ship latitudinal motion control, a model test system for active control of ship latitudinal motion is designed. According to the system, the demonstration and verification test for ship control schemes and rules were carried out. Meanwhile, a “PC/data acquisition and network module” flexible design scheme was adopted to build a demonstration platform for this type of...
This paper proposes a new method for human posture recognition from top-view depth maps on small training datasets. There are two strategies developed to leverage the capability of convolution neural network (CNN) in mining the fundamental and generic features for recognition. First, the early layers of CNN should serve the function to extract feature without specific representation. By applying the...
In this paper, Ti-doped GaZnO (GTZO) quaternary alloys were used as the transparent conductive oxides (TCOs) for Cu(In, Ga)SeSe2 (CIGS) solar cell application. These thin films are highly favorable for solar power systems. Photoluminescence measurement and X-ray diffraction were employed to investigate the GTZO thin films. Advantageous crystal quality was produced by radio-frequency magnetron sputtering...
In this study, two transparent thin-film transistors (TFTs) with distinct channel designs were fabricated. The first was a single channel TFT (SC-TFT) with a typical 50-nm-thick amorphous indium-gallium-zinc oxide (a-IGZO) layer, and the second was a sandwich composite-channel TFT (CC-TFT) comprising three layers of 10-/30-/10-nm-thick Ti-doped GaZnO (GTZO)/a-IGZO/GTZO. In the CC-TFT, the bottom GTZO...
300W end-pump power deposited as heat is predicted to cause a thermal damage for doped double clad fiber (DDCF). In order to estimate cooling effects of DDCF through radiator, the general equation has been solved with a thermal convection boundary under a rectangular plate at the periphery. Steady-state thermal profiles are developed using both a full numerical solution and an analytic approximation...
Molecular dynamics (MD) simulations were carried out to study the mechanical properties of co-continuous Al/SiC nanocomposites under tensile loading. Three cases of different models were implemented to investigate the influence of volume fraction (Vf) of SiC, thickness of SiC skeletons and shape of Al nanowire on the mechanical properties of the nanocomposites. It is found that the ultimate strength...

This paper aims to design microchannel heat sink for high power modules cooling based on topology optimization method to obtain better...
Lower energy consumption, higher conversion efficiency, and longer life lead to a widely use of light emitting diode (LED) in illumination applications. However, the long product life makes it difficult to do reliability test due to the long time it cost. Generally, the reliability performance of the LED is evaluated by thermal cycling and thermal shock. In this paper, a new reliability testing method...
A distributed sensing network using a chirped ultra-weak fiber Bragg grating array is proposed and experimentally demonstrated. This network is based on time-division multiplexing (TDM) technique. We use a path-match interferometry to obtain interference signal, then amplitude, phase, frequency and location information can be demodulated from interference signal by employing the passive 3 × 3 coupler...

An ultrasonic torsional tool is fabricated according to the presented method,...
As an important research part of ship intelligence and networking, the communication quality of ship information system is affected by its closeness and fragility which has increased the risk of cyberattack in ship environment. However, before the research of defense mechanisms, the study of attack in ship information system has its own irreplaceable value. Therefore, in this paper, some systematic...
III-nitride based nanostructures have gained interest as nanoscale light sources in the UV to visible wavelengths. Here we present a top-down approach to enable vertical, high aspect ratio III-nitride-based nanowires with controllable height, pitch, and diameter. Additionally, through the use of orientation-dependent etch rate measurements, the cross-sections of such nanostructures can be predicted...
Gather/scatter are state of the art vector memory access modes in Vector-SIMD architectures. However, because of the stochastic and complicated properties, the hardware design of gather/scatter operations lacks theoretical analysis and modeling. This paper proposes a model for gather/scatter operations on local vector memory for the first time. The model can not only give all the possible distributions...
For frequencies below their fundamental electronic bandgap energy, nanoparticles made from semiconductor materials can sustain electric and magnetic multipolar Mie-type resonances. Owing to the possibility to tailor these resonances by the nanoparticle geometry in combination with their low nonradiative damping rates in comparison to plasmonic nanoparticles, such semiconductor nanoparticles have recently...
When encountering a packet for which it has no matching forwarding rule, a software-defined networking (SDN) switch requests an appropriate rule from its controller; this request delays the routing of the flow until the controller responds. We show that this delay gives rise to a timing side channel in which an attacker can test for the recent occurrence of a target flow by judiciously probing the...
