A Power and Data Decoupled Transmission Method for Wireless Power Transfer Systems via a Shared Inductive Link (2018)

Wireless Power Transfer (WPT) technology is gaining global popularity. However, in some applications, data transmission is also required to monitor the load states. This paper presents an alternative wireless power and data transmission method via the shared inductive link. With the method, the system presents three characteristics: (1) controllability and stability of the output voltage; (2) miniaturization in volume of the system; (3) decoupled transmission of power and data. The output voltage control is realized by a non-inductive hysteresis control method. In particular, data is transferred when the power transmission is blocked (i.e., the hysteresis switch is off). The interference between power and data transmission is very small. The signal to noise ratio (SNR) performance which is relevant to the interference from power transfer to data transfer and data transfer capacity, is studied and optimized. Both simulation and experimental results have verified the proposed method.
Free-Space Estimation for Self-Driving System Using Millimeter Wave Radar and Convolutional Neural Network (2019)

Recently, autonomous vehicles are gaining a lot of attention and their R&D are conducted in various institutions. A vehicle should be able to change lanes for achieving full autonomous status. Using millimeter wave radar is cost-effective however it detects only a few points. To solve this problem, we propose a method to approximate free space generated by millimeter wave radar data to the free space generated by LIDAR data using CNN. The result shows that CNN enables to close to the LIDAR by an average of 1.5 m.
A face antispoofing database with diverse attacks (2012)

Face antispoofing has now attracted intensive attention, aiming to assure the reliability of face biometrics. We notice that currently most of face antispoofing databases focus on data with little variations, which may limit the generalization performance of trained models since potential attacks in real world are probably more complex. In this paper we release a face antispoofing database which covers a diverse range of potential attack variations. Specifically, the database contains 50 genuine subjects, and fake faces are made from the high quality records of the genuine faces. Three imaging qualities are considered, namely the low quality, normal quality and high quality. Three fake face attacks are implemented, which include warped photo attack, cut photo attack and video attack. Therefore each subject contains 12 videos (3 genuine and 9 fake), and the final database contains 600 video clips. Test protocol is provided, which consists of 7 scenarios for a thorough evaluation from all possible aspects. A baseline algorithm is also given for comparison, which explores the high frequency information in the facial region to determine the liveness. We hope such a database can serve as an evaluation platform for future researches in the literature.
A New Laser Micromachining System for the Fabrication of THz Waveguide and Quasi-Optical Components (2000)

The insulin-like growth factors (IGF) system, and particularly the IGF-1 receptor, has recently become the subject of major interest in the arena of cancer research. Its involvement in cancer cell growth and survival makes the system an excellent target as potential adjunct therapy to standard chemotherapy.
Numerical methods for the migration of constant-offset sections in homogeneous and horizontally layered media (1983)

Abstract Migration can be viewed in the time domain as a process whereby the plane waves echoed from a source to a geophone by a reflecting point are shifted in time to a common intersection. The time shift determines the phase shift applicable in the frequency domain to the associated Fourier component of the seismic section. Table of shifts for an appropriate sample of plane-wave directions, to be used for interpolation in the migration process. Computer experiments with synthetic data.--Modified journal abstract.
Generation of Her-2/neu vaccine utilizing idiotypic network cascade (2007)

Our goal is to apply an anti-idiotype (Id) antibody based vaccine approach for the treatment of Her-2/neu-positive human cancer. Amplification and/or overexpression of Her-2/neu occur in multiple human malignancies and are associated with poor prognosis. The Her-2/neu proto-oncogene is a suitable target for cancer immunotherapy. Our strategy is active specific immunotherapy in which patients immunized with an anti- Id antibody mimicking Her-2/neu will generate sustained high titer Her-2/neu specific protective antibodies. We have used an anti-Her-2/neu murine monoclonal antibody 4D5 as the immunizing antibody (Ab1) against which monoclonal anti-Ids or Ab2s were generated in syngeneic mice. We have characterized one such anti-Id (Ab2) designated 6D12, which mimics a specific epitope of Her-2/neu as defined by Trastuzumab, and can be used as a surrogate antigen for Her-2/neu across the species barriers. Immunization of allogeneic mice or rabbits with 6D12 induced anti-anti-Id (Ab3), that specifically recognized Her-2/neu-positive tumor cells and lysed these cells in culture by antibody-dependent cellular cytotoxicity (ADCC). Monoclonal Ab3 generated in mice against 6D12 inhibited the proliferation of Her-2/neu-positive SK-BR-3 cells in vitro in a dose dependent fashion and delayed the growth of Her-2/neu transfected EL4-Her-2 cells in vivo. These data suggest the potential use of 6D12 as a vaccine for Her-2/neu-positive human cancer.

The impact of Mpact 2 (1998)

Mpact media processors enable powerful, flexible and cost-effective multimedia in a PC. A single chip replaces today's multiboard, multichip solutions for graphics, video, audio, and communications. The architecture combines a high-bandwidth RAMBUS memory, VLIW/SIMD (single instruction, multiple data) processing, standard buses, and software programmability for the cost of a modern graphics chip. Mpact architecture uses a modified VLIW style with two RISC-like instructions per VLIW. The instructions are either executed sequentially or concurrently based on a tag in the VLIW. Classical VLIW suffers from low code density due to unused instruction fields, but the Mpact modified VLIW has the same code density as RISC instructions. Additionally, the SIMD instructions improve code density by increasing the work done by each instruction. An 8 byte word size was chosen to balance vector and scalar performance and also to balance data and instruction bandwidth. A 9 bit byte was chosen to represent color-component differences in one byte and to represent 18 bit color or 18 bit audio samples in two bytes. Hardware-dithered rounding of quantization noise allows most audio to be processed in two byte precision. The maximal multiplier precision of 24/spl times/24 was chosen for audio requirements. The article reviews the first-generation Mpact media processor and then describes the multimedia performance goals and architecture of Chromatic's second-generation media processor architecture. It then presents newer modules of the architecture in more detail.
Interleukin-4 and -13 Inhibit Tumor Necrosis Factor-α mRNA Translational Activation in Lipopolysaccharide-induced Mouse Macrophages (1997)

The production of tumor necrosis factor-alpha (TNF-alpha) by lipopolysaccharide (LPS)-stimulated macrophages can be markedly inhibited by the two closely related cytokines, interleukin (IL)-4 and IL-13. To investigate the molecular mechanism of this inhibition, we analyzed the effect of the two cytokines on TNF-alpha production and TNF-alpha mRNA accumulation in the mouse macrophage cell lines RAW 264.7 and J774 stimulated by LPS. Whereas LPS-induced TNF-alpha production is strongly suppressed by both cytokines, TNF-alpha mRNA accumulation is not significantly affected, indicating that IL-4 and IL-13 induce a translational repression of TNF-alpha mRNA. Transfection of reporter gene constructs containing different regions of the TNF-alpha gene revealed that the inhibitory action of IL-4 and IL-13 is mediated by the UA-rich sequence present in the TNF-alpha mRNA 3'-untranslated region.
Geometric finiteness and uniqueness for Kleinian groups with circle packing limit sets (1991)

In this paper, we assume that $G$ is a finitely generated torsion free non-elementary Kleinian group with $Ω(G)$ nonempty. We show that the maximal number of elements of $G$ that can be pinched is precisely the maximal number of rank 1 parabolic subgroups that any group isomorphic to $G$ may contain. A group with this largest number of rank 1 maximal parabolic subgroups is called {\it maximally parabolic}. We show such groups exist. We state our main theorems concisely here. Theorem I. The limit set of a maximally parabolic group is a circle packing; that is, every component of its regular set is a round disc. Theorem II. A maximally parabolic group is geometrically finite. Theorem III. A maximally parabolic pinched function group is determined up to conjugacy in $PSL(2,{\bf C})$ by its abstract isomorphism class and its parabolic elements.
Reversing the hydrogen silsesquioxane image by silicon nitride and silicon oxide chemical mechanical polishing (2006)

Patterns, e-beam written in hydrogen silsesquioxane (HSQ), have been reversed in tone by chemical mechanical polishing of silicon nitride deposited on top of these HSQ patterns. First, high-resolution patterns have been written in an 80nm thick HSQ layer on a 6in. silicon wafer. After development, 200nm thick plasma enhanced chemical vapor deposited silicon nitride has been deposited at 300°C on top of these patterns. Next, the silicon nitride has been Syton polished down to 50nm thickness. Finally, the HSQ has been removed wet chemically from in between the nitride features using buffered oxide etch (7:1). Features of 50nm wide have been resolved, but even smaller isolated spaces are feasible. The same method has been tested with silicon oxide obtained from boron doped tetraethyl orthosilicate. Although the wet-chemical removal of HSQ is less selective in this case, still 50nm wide features have been resolved in silicon oxide this way.

Microfluidic Synthesis of Monodisperse Nanoporous Oxide Particles and Control of Hierarchical Pore Structure (2013)

Particles with hierarchical porosity can be formed by templating silica microparticles with a specially designed surfactant micelle/oil nanoemulsion mixture. The nanoemulsion oil droplet and micellar dimensions determine the pore size distribution: one set of pores with diameters of tens of nanometers coexisting with a second subset of pores with diameters of single nanometers. Further practical utility of these nanoporous particles requires precise tailoring of the hierarchical pore structure. In this synthesis study, the particle nanostructure is tuned by adjusting the oil, water, and surfactant mixture composition for the controlled design of nanoemulsion-templated features. We also demonstrate control of the size distribution and surface area of the smaller micelle-templated pores as a consequence of altering the hydrophobic chain length of the molecular surfactant template. Moreover, a microfluidic system is designed to process the low interfacial system for fabrication of monodisperse porous particles. The ability to direct the assembly of template nanoemulsion and micelle structures creates new opportunities to engineer hierarchically porous particles for utility as electrocatalysts for fuel cells, chromatography separations, drug delivery vehicles, and other applications.
Advances in Animal Models of Hepatitis B Virus Infection (2015)

Abstract Hepatitis B virus (HBV) infection seriously affects human health. Stable and reliable animal models of HBV infection bear significance in studying pathogenesis of this health condition and development of intervention measures. HBV exhibits high specificity for hosts, and chimpanzee is long used as sole animal model of HBV infection. However, use of chimpanzees is strictly constrained because of ethical reasons. Many methods were used to establish small-animal models of HBV infection. Tupaia is the only nonprimate animal that can be infected by HBV. Use of HBV-related duck hepatitis virus and marmot hepatitis virus infection model contributed to evaluation of mechanism of HBV replication and HBV treatment methods. In recent years, development of human–mouse chimeric model provided possibility of using common experimental animals to carry out HBV research. These models feature their own advantages and disadvantages and can be complementary in some ways. This study provides an overview of current and commonly used animal models of HBV infection.
Regulation of methionine transport activity in Escherichia coli (1975)

Methionine transport activity in cells of Escherichia coli K-12 is regulated by the level of the internal methionine pool. Transport activity is depressed either in cells grown in the presence of methionine or in cells exposed to methionine immediately prior to harvest. Alpha-Keto-gamma-methiol-butyrate, D-methionine, or methionine sulfoxide have little effect on the initial rate of uptake of L-methionine when they are added simultaneously with the substrate. However, methionine transport is markedly reduced in cells exposed to these sources of L-methionine before the addition of substrate. This reduction is prevented if the cells are treated with amino oxyacetic acid. The initial rate of uptake into L-methionine-loaded cells was lower than that into unloaded cells. This inhibition affected both methionine transport systems and the inhibition by the internal pool appeared to be non-competitive with the external methionine concentration. Two classes of mutants with increased methionine pools have decreased rates of uptake. Conversely, starvation for methionine in a methionine auxotroph with high rates of methionine degradation resulted in a substantial increase in the rate of methionine transport. Thus, these transport systems are subject to regulation by the internal pool size and possibly by repression.
Adventures in Carbohydrate Chemistry: New Synthetic Technologies, Chemical Synthesis, Molecular Design, and Chemical Biology A list of abbreviations can be found at the end of this article. Telemachos Charalambous was an inspiring teacher at the Pancyprian Gymnasium, Nicosia, Cyprus. (2001)

The field of carbohydrate chemistry has occupied the minds and hearts of many scientists for over a hundred years and, as we enter the twenty-first century, it continues to be both vigorous and challenging. Among the most exciting aspects of organic chemistry in the last few decades has been the interplay between the specialized subdisciplines of carbohydrate chemistry and total synthesis, each enabling and advancing the other in new directions and towards greater heights. In this review article we highlight our own adventures at the interface of these disciplines, which were driven for the most part by objectives in chemical synthesis and chemical biology. Specifically, we describe our interests and efforts to utilize carbohydrates as starting materials for total synthesis, to invent and develop new synthetic technologies for carbohydrate synthesis, to construct complex oligosaccharides in solution or on solid support, and to utilize carbohydrate templates as scaffolds for peptide mimetics and for molecular diversity construction. Finally, applications of the developed synthetic strategies and enabling technologies towards the solution of biologically significant problems are discussed.
The Enigma PAI-2. Gene Expression, Evolutionary and Functional Aspects (1995)

The type-2 plasminogen activator inhibitor (PAI-2) belongs to the ovalbumin subfamily of serpins. It exhibits close to 50% homology with several recently cloned protease inhibitors such as the leukocyte elastase inhibitor, the placental thrombin inhibitor and the squamous cell carcinoma antigen. PAI-2 exists in an intracellular, nonglycosylated form of 47 kDa and a secreted, glycosylated form of about 60 kDa. The PAI-2 gene does not have a signal peptide which might explain why the major portion of PAI-2 remains intracellularly. Several response elements have been identified in the promoter region which are necessary for constitutive and phorbol ester and retinoic acid induced expression of the gene. These include two AP-1 sites, and response elements for cAMP, glucocorticoids and retinoic acid. The physiological function of PAI-2 has not been clearly elucidated. It may have cytoprotective functions and appears to play a role in programmed cell death.
Specification and calibration of a multi-frequency MEIT system for stroke (2005)

The performance of a modified MEIT system was investigated, using a resistor phantom, for the imaging of stroke based on specifications revealed in recent modelling (Horesh et al, 2005). Using ideal calibration the system does not meet the specifications as the variation over the load is 0.9%, variation over frequency is +/-1.5 % and variation over electrode combinations is +/-2 % exceeding the better than 1 % requirement over 20-500kHz and 1 to 66 Ω. However this system has been useful in imaging gastric emptying (Soulsby et al, 2005); extending to lower frequencies should aid this application along with further epilepsy trials (Fabrizi et al, 2005).
Calcinosis Cutis Complicated by Compartment Syndrome Following Extravasation of Calcium Gluconate in a Neonate: A Case Report (2010)

Hypocalcemia most frequently occurs in premature neonates. It is usually treated by intravenous (iv) calcium supplementation. However, complications caused by extravasation of iv calcium gluconate include localized soft tissue calcification, necrosis, cellulitis, osteomyelitis, and even compartment syndrome. We present a rare case of iatrogenic calcinosis cutis complicated by compartment syndrome secondary to extravasation of iv calcium gluconate in a neonate. Emergent fasciotomy was performed twice for decompression of compartment syndrome. Histologic findings revealed necrosis and calcification. Appropriate antibiotics were administered to control secondary infection. To the best of our knowledge, there were no previous case reports of calcinosis cutis with compartment syndrome in infants. Although iatrogenic calcinosis cutis is generally a benign entity, the early recognition of the presentation of extravasation of calcium gluconate is important to avoid severe complications and possible medical malpractice disputes. This report aims to raise doctors' awareness of the presentation, course, and management of this relatively rare iatrogenic complication.
13. Genotoxicity of Metal Ions: Chemical Insights (2010)

The purpose of this review is to provide a reader with a brief account of current results and views in the area of genotoxicity of metal ions, with a special attention to underlying chemical mechanisms. The text is divided into six sections. Following a general introduction in Section 1, Section 2 describes main molecular mechanisms of formation of genotoxic lesions: hydrolysis, alkylation, and radical reactions of nucleobases and the phosphosugar DNA backbone. The basics of cellular repair of DNA lesions are also shortly presented. This section serves as a background source for Sections 3, 4, and 5. Section 3 covers the main mechanisms of metal ion genotoxicity, followed by Section 4, which describes genotoxicity of individual metals; i.e., of the confirmed carcinogens As, Be, Cd, Cr, and Ni, as well as of the suspected carcinogens Co, Cu, Fe, Pb, Pt, and 238U (also known as depleted uranium). The genotoxicity of exposures to metal mixtures is also discussed. Section 5 provides a critical overview of methodologies used for studying mutagenicity and carcinogenicity of metals; the final Section 6 summarizes the current state and future perspectives of research in genotoxic mechanisms of metal ions.

They describe the architecture of each application class and address performance issues in respect to the communication parameters.
Kinetics of Formation of Peroxyformic Acid (1996)

Oxidation kinetics of formic acid with aqueous hydrogen peroxide (30-70%) has been studied at 45 °C with 0-0.1 M H 2 SO 4 as a catalyst. A kinetic model has been suggested which satisfactorily describes the oxidation process of formic acid to peroxyformic acid.
