Abstract- Carbon nanotubes (CNTs) has been coated on the surface of LiNi0.45Al0.05Mn1.5O4 cathode material and the effect of carbon nanotube coating on the electrochemical performances is investigated through the characterization of X-ray diffraction (XRD), cyclic voltammetry (CV), galvanostatic charge-discharge test and electrochemical impedance spectroscopy (EIS), respe.ctively. The results reveal...
The next-generation implantable high-power prosthetic devices, such as retinal prostheses, will be powered by inductively coupled coils of high efficiency. However, the use of high-frequency power carriers almost always induces significant AC resistance due to skin and proximity effects, which limits the overall coupling efficiency. Inspired by the widely used round Litz wire, planar coils with planar...
Parkinson's disease (PD) is a common degenerative neurological disorder. Freezing of Gait (FOG) is a significant symptom in PD. Sudden FOG causes balance disturbances and increases the risk of falls. An online approach for FOG identification is presented using MiMed-Pants and an online test software with a frequency-time combined algorithm. MiMed-Pants are washable jogging-trousers with integrated...
By focusing on relations between latecomer disruptors and incumbents that go beyond competitive interactions, we give a fresh perspective to the Disruptive Innovation literature. This paper uses case study to investigate Disruptive Innovation cases in China's high-tech industries and identifies unique situations where both latecomer disruptors and incumbents can benefit from cooperation. This kind...
A novel converter is proposed in this paper to satisfy the high power and high step-up conversion requirements. A voltage gain extension cell based on the coupled inductors and the blocking capacitor is introduced in the conventional interleaved boost converter to extend the voltage conversion ratio and reduce the switch voltage stresses. Therefore, low on-resistance switches can be used to reduce...
Extraneous thermal motion can limit displacement sensitivity and radiation pressure effects, such as optical cooling, in a cavity-optomechanical system. Here we present an active noise suppression scheme and its experimental implementation.
Parkinson's disease (PD) is a degenerative neurological disorder. Patients suffer from different movement disturbances. Amongst others, freezing of gait (FOG) is a common and disabling feature. A new method for FOG detection using a garment with integrated accelerometers, the MiMed-Pants, is presented and evaluated. MiMed-Pants are loose fitting washable pants for measuring movements and were previously...
For the sake of measuring fuzzy uncertainty and rough uncertainty of real datasets, the fuzzy rough membership function (FRMF) defined in fuzzy rough set is introduced. A new fuzzy rough neural network (FRNN) is constructed based on neural network implementation of FRMF. FRNN has the merits of quick learning and good classification performance. And then a new neural network feature selection algorithm...
Contacts of vacuum interrupters have important influence on nominal current carrying capability and short circuit current interrupting capacity of vacuum circuit breakers. The contact with longitudinal magnetic field has the capacity of good open and close short circuit current, this field can reduce loss of radial energy of arc post plasma and make the arc voltage reduce. This paper has studied electromagnetic...
Silicon SoCs capable of millimeter-wave frequency operation now offer a combination of performance, functionality, integration scale and cost unrivalled by other IC technologies.

The present study is to find an efficient method for extracting pilose antler polypeptide (PAP), and the immunological function of PAP was systematically evaluated. Sephadex G-50 Molecular exclusion chromatography and CM-Sepharose Fast Flow ion exchange chromatography were used to extract PAP which is more efficient than traditional method. Spleen lymphocyte proliferation assays and cytokine IL-12...
The study aims to find some other functions of IL-7 in control TB and screen a new host marker in small groups of TB patients and controls to identify promising markers for large-scale testing. Real-time RT-PCR is used to evaluate the stability of IL-4 and IL-7 mRNA in the presence of Actinomycin D in whole blood from active TB cases and uninfected healthy controls. Flow cytometry and cytokine secretion...
A compact antenna for dual-band operation is presented. The proposed antenna consists of a C-shaped ground plane and an L-shaped monopole radiator. The Γ-shaped stub extending from the ground can achieve a resonance covering the lower band, whereas the L-shaped monopole operates at the upper band. The antenna prototype is designed, fabricated and tested. The experimental results show the antenna covers...
We present BTLab, a distributed platform to measure and analyze the differences between BitTorrent clients. Due to extensibility, and a certain vagueness in the BitTorrent specification, many clients diverge in some aspects from each other. Most research to date disregarded the effects of these differences. BTLab allows us to create and control BitTorrent swarms, composed of hundreds of clients of...
This paper presents a lens-integrated terahertz imaging detector implemented in a 65 nm bulk CMOS process technology. The back-side illumination through a silicon lens increases the imaging SNR by 7–15 dB. The broadband detector design has been verified from 0.6 to 1 THz. At 1 THz the circuit achieves a noise equivalent power (NEP) of 66 pW/sqrt(Hz) and a responsivity (Rv) of 800 V/W for back-side...
