Love Postoperative ECG Shell (I)
Ongoing cutting-edge multidisciplinary research in textile fibers, biomedical sensors, and wireless and mobile telecommunications integrated with telemedicine, aims at developing intelligent biomedical clothing (IBC). This ECG shell design is a functional garment offering, health benefits, improved appearance and increased comfort. The garment is more comfortable because the high adhesive factor of current commercial hydrogel used in ECG monitoring causes patients skin allergies and pruritus from wearing the hydrogel for a long time
Love Postoperative ECG T-shirt (II)
This ECG T-shirt is a functional garment offering, health benefits, improved appearance and increased comfort. The garment is more comfortable because the high adhesive factor of current commercial hydrogel used in ECG monitoring causes patients skin allergies and pruritus from wearing the hydrogel for a long time. Additionally, since the sensors are attached to the lining of this two-layer raglan T-shirt, the exterior is smooth and makes the user tracking device inconspicuous
Design And Fabrication of Condenser Microphone Using Wafer Transfer And Micro-electroplating Technique
A novel fabrication process, which uses wafer transfer and
micro-electroplating technique, has been proposed and tested. In this paper,
the effects of the diaphragm thickness and stress, the air-gap thickness, and
the area ratio of acoustic holes to backplate on the sensitivity of the
condenser microphone have been demonstrated since the performance of the
microphone depends on these parameters. The microphone diaphragm has been
designed with a diameter and thickness of 1.9 mm and 0.6 m, respectively,
an air-gap thickness of 10 m, and a 24% area ratio of acoustic holes to
backplate. To obtain a lower initial stress, the material used for the
diaphragm is polyimide. The measured sensitivities of the microphone at the
bias voltages of 24 V and 12 V are -45.3 and -50.2 dB/Pa (at 1 kHz),
respectively. The fabricated microphone shows a flat frequency response
extending to 20 kHz.Comment: Submitted on behalf of EDA Publishing Association

Fever Screening at Airports and Imported Dengue
Airport fever screening in Taiwan, July 2003–June 2004, identified 40 confirmed dengue cases. Results obtained by capture immunoglobulin (Ig) M and IgG enzyme-linked immunoassay, real time 1-step polymerase chain reaction, and virus isolation showed that 33 (82.5%) of 40 patients were viremic. Airport fever screening can thus quickly identify imported dengue cases
Distilling portable Generative Adversarial Networks for Image Translation
Despite Generative Adversarial Networks (GANs) have been widely used in
various image-to-image translation tasks, they can be hardly applied on mobile
devices due to their heavy computation and storage cost. Traditional network
compression methods focus on visually recognition tasks, but never deal with
generation tasks. Inspired by knowledge distillation, a student generator of
fewer parameters is trained by inheriting the low-level and high-level
information from the original heavy teacher generator. To promote the
capability of student generator, we include a student discriminator to measure
the distances between real images, and images generated by student and teacher
generators. An adversarial learning process is therefore established to
optimize student generator and student discriminator. Qualitative and
quantitative analysis by conducting experiments on benchmark datasets
demonstrate that the proposed method can learn portable generative models with
strong performance
Discovery of serum biomarkers of alcoholic fatty liver in a rodent model: C-reactive protein
<p>Abstract</p> <p>Background</p> <p>Excessive consumption of alcohol contributes to alcoholic liver disease. Fatty liver is the early stage of alcohol-related liver disease. The aim of this study was to search for specific serological biomarkers of alcoholic fatty liver (AFL) compared to healthy controls, non-alcoholic fatty liver (NAFL) and liver fibrosis in a rodent model.</p> <p>Methods</p> <p>Serum samples derived from animals with AFL, NAFL, or liver fibrosis were characterized and compared using two-dimensional differential gel electrophoresis. A matrix-assisted laser desorption ionization-time of flight tandem mass spectrometer in conjunction with mascot software was used for protein identification. Subsequently, Western blotting and flexible multi-analyte profiling were used to measure the expressions of the putative biomarkers present in the serum of animals and clinical patients.</p> <p>Results</p> <p>Eight differential putative biomarkers were identified, and the two most differentiated proteins, including upregulated C-reactive protein (CRP) and downregulated haptoglobin (Hp), were further investigated. Western blotting validated that CRP was dramatically higher in the serum of AFL compared to healthy controls and other animals with liver disease of NAFL or liver fibrosis (<it>p </it>< 0.05). Moreover, we found that CRP and Hp were both lower in liver fibrosis of TAA-induced rats and clinical hepatitis C virus-infected patients.</p> <p>Conclusion</p> <p>The results suggest that increased levels of CRP are an early sign of AFL in rats. The abnormally elevated CRP induced by ethanol can be used as a biomarker to distinguish AFL from normal or otherwise diseased livers.</p
Current reversals and metastable states in the infinite Bose-Hubbard chain with local particle loss
We present an algorithm which combines the quantum trajectory approach to
open quantum systems with a density-matrix renormalization group scheme for
infinite one-dimensional lattice systems. We apply this method to investigate
the long-time dynamics in the Bose-Hubbard model with local particle loss
starting from a Mott-insulating initial state with one boson per site. While
the short-time dynamics can be described even quantitatively by an equation of
motion (EOM) approach at the mean-field level, many-body interactions lead to
unexpected effects at intermediate and long times: local particle currents far
away from the dissipative site start to reverse direction ultimately leading to
a metastable state with a total particle current pointing away from the lossy
site. An alternative EOM approach based on an effective fermion model shows
that the reversal of currents can be understood qualitatively by the creation
of holon-doublon pairs at the edge of the region of reduced particle density.
The doublons are then able to escape while the holes move towards the
dissipative site, a process reminiscent---in a loose sense---of Hawking
radiation
Study on the Stability of DeoxyArbutin in an Anhydrous Emulsion System
The skin-whitening agent, deoxyArbutin, is a potent tyrosinase inhibitor that is safer than hydroquinone and arbutin. However, it is thermolabile in aqueous solutions, where it decomposes to hydroquinone. Pharmaceutical and cosmetic emulsions are normally oil-in-water (o/w) or water-in-oil (w/o) systems; however, emulsions can be formulated with no aqueous phase to produce an anhydrous emulsion system. An anhydrous emulsion system could offer a stable vehicle for compounds that are sensitive to hydrolysis or oxidation. Therefore, to enhance the stability of deoxyArbutin in formulations, we chose the polyol-in-silicone, anhydrous emulsion system as the basic formulation for investigation. The quantity of deoxyArbutin and the accumulation of hydroquinone in both hydrous and anhydrous emulsions at various temperatures were analyzed through an established high performance liquid chromatographic (HPLC) method. The results indicated that water increased the decomposition of deoxyArbutin in the formulations and that the polyol-in-silicone, oil-based, anhydrous emulsion system provided a relatively stable surrounding for the deoxyArbutin that delayed its degradation at 25 °C and 45 °C. Moreover, the composition of the inner hydrophilic phase, containing different amounts of glycerin and propylene glycol, affected the stability of deoxyArbutin. Thus, these results will be beneficial when using deoxyArbutin in cosmetics and medicines in the future
