A Two-stage Digital AGC Scheme with Diversity Selection for Frame-based OFDM Systems (2006)

This paper addresses a digital automatic gain control (AGC) strategy for frame-based orthogonal frequency-division multiplexing (OFDM) systems. Two stages of gain adjustment are adopted to adjust gain accurately and rapidly. Magnitude level of received signal is calculated over short and long period in two stages, respectively. Appropriate volumes of gain adjustment are then obtained by subtracting the estimated levels from the desired level of ADC. Next, digital volumes of gain adjustment are converted into analog control signals for variable gain amplifiers. Short stage deals with various situations as well as coarse gain adjustment. Long stage adjusts gain accurately with no more than 4 % inaccuracy of the desired level. The proposed digital AGC approach help raise SNR of received signals, enable subsequent receiver algorithms to operate efficiently with the robust signals. Additionally, the proposed approach can be easily implemented in conventional CMOS technology
Impacts of uncertain river flow data on rainfall‐runoff model calibration and discharge predictions (2010)

Abstract In order to quantify total error affecting hydrological models and predictions, we must explicitly recognize errors in input data, model structure, model parameters and validation data. This paper tackles the last of these: errors in discharge measurements used to calibrate a rainfall‐runoff model, caused by stage–discharge rating‐curve uncertainty. This uncertainty may be due to several combined sources, including errors in stage and velocity measurements during individual gaugings, assumptions regarding a particular form of stage–discharge relationship, extrapolation of the stage–discharge relationship beyond the maximum gauging, and cross‐section change due to vegetation growth and/or bed movement. A methodology is presented to systematically assess and quantify the uncertainty in discharge measurements due to all of these sources. For a given stage measurement, a complete PDF of true discharge is estimated. Consequently, new model calibration techniques can be introduced to explicitly account for the discharge error distribution. The method is demonstrated for a gravel‐bed river in New Zealand, where all the above uncertainty sources can be identified, including significant uncertainty in cross‐section form due to scour and re‐deposition of sediment. Results show that rigorous consideration of uncertainty in flow data results in significant improvement of the model's ability to predict the observed flow. Copyright © 2010 John Wiley & Sons, Ltd.
Protective Effects of Tea Polysaccharides and Polyphenols on Skin (2009)

The protective effects of tea polysaccharides (TPS) and polyphenols (TPP) on skin were investigated. TPS1 (92% TPS), crude TPS2 (20% TPS), and TPP (98%) were tested. The abilities of TPS and TPP to protect the skin were assessed in four aspects: moisture absorption and retention, sunscreen, promoting the proliferation of fibroblast cells, and tyrosinase inhibitory effect. TPS and TPP absorbed and reserved moisture perfectly. TPS with higher purity had better moisture absorption and retention abilities. TPS1 hardly protected the skin from the sun's ultraviolet (UV) rays and had little promoting effect on fibroblasts proliferation. TPP, however, protected skin against UV rays and enhanced proliferation of fibroblast cells significantly. TPP had good tyrosinase inhibitory effects; TPS showed weaker tyrosinase inhibitory effects with the purity increased. The results indicated that TPP and TPS had complementary advantages and they should be appropriately combined to achieve higher performance when applied as active components of cosmetics.
Solvent effect in radical copolymerization. II. N.N‐dimethyl acrylamide (1971)

Abstract The free radical copolymerization of N.N‐dimethyl acrylamide with styrene or methyl methacrylate has been carried out at 70°C in solvents of different dielectricity constants. The present work does not show the strong solvent influence on copolymer compositions previously found for acrylamide copolymerizations. The influence of the presence of two alkyl groups on the amidic nitrogen is discussed. The calculated copolymerization parameters agree with the values obtained by other authors.
INCREMENT PUNCHER: A tool for extracting small cores of wood and bark from living trees (2000)

A newly designed and easy-to-use increment puncher (in French: minisonde de prélèvement; in German: Zuwachsstecher; in Italian: puntura incrementale) allows the extraction of wood and bark cores from living tree stems for the study of radial increment, cell wall formation, lignification and wound reactions. This article describes the technical features and gives instructions for use. The biological reactions in the injured zone surrounding the punched holes are presented in a case study on eastern white cedar ( Thuja occidentalis L.).
Effect of acepromazine on the anesthetic requirement of halothane in the dog (1986)

Five adult dogs were used to determine whether acepromazine maleate (ACP), administered IM, decreases the maintenance requirement of halothane and to measure any decrease for the ACP dosages of 0.02, 0.04, 0.06, 0.08, 0.10, and 0.20 mg/kg. The value minimal alveolar concentration, a measure of anesthetic potency, was used as the measure of anesthetic requirement of halothane before and after ACP was administered. All dogs were randomly exposed to each dosage of ACP, as well as to control of 0.2 ml of sterile water. At all dosages of ACP, the decrease in the minimal alveolar concentration of halothane was significant (P less than or equal to 0.05) when compared with that of the control. The decreases at the 0.04 and 0.20 mg/kg dosages were significantly (P less than or equal to 0.05) greater than those at the 0.02 and 0.06 mg/kg dosages. Halothane requirements at all other ACP dosages (0.08 and 0.10 mg/kg) were not significantly different from each other or from those at any of the other dosages. The percentage of decrease in anesthetic requirement after ACP was administered varied from 34% to 46%, with a mean decrease of 40%. The largest decrease was recorded at the dosage of 0.04 mg/kg.
An open real-time tele-stethoscopy system (2012)

It has been shown that real-time tele-stethoscopy, together with a videoconference system that allows a remote specialist to oversee the auscultation, may be a very helpful tool in rural areas of developing countries.
Adenosine A<sub>2a</sub> receptor expression in striatal neurons: Implications for basal ganglia pathophysiology (1993)

Abstract Two dog adenosine receptors have been recently cloned. They were pharmacologically characterized as an A 1 and the A 2a receptor, respectively. The adenosine A 2a receptor is exclusively expressed in medium‐sized neurons of the striatum as demonstrated by in situ hybridization. The relationships of this A 2a receptor with three major components of the striatum, enkephalin, substance P, and choline acetyltransferase, were studied in the rat. This demonstrates that the adenosine A 2a receptor is exclusively expressed by the enkephalinergic striatal neuronal subpopulation that also selectively expresses the dopamine D2 receptor. Conversely, The A 2a receptor is never detected in the substance P containing neurons or in the cholinergic neurons. This observation most probably constitutes the anatomical substratum for the preciously described A 2a ‐D2 receptors interactions. It also indicates that A 2a receptor is selectively express in the indirect pathway of the basal ganglia system which is hypoactive in hyperkinetic disorders such as Huntington's disease and hyperactive in hypokinetic disorders such as Parkinson's disease. The development of highly A 2a selective ligands could be therefore useful in the therapy useful in the therapy of basal ganglia degenerative diseases. © 1993 Wiley‐Liss, Inc.
Analysis of the Mean Diameters and Particle‐Size Distribution in Powders (2010)

Abstract The granulometric characterization of a pulverulent material requires quantification of the particle size and its distribution frequency. From these primary data, the mean size (mean diameters) of the pulverulent material is calculated and the data are adjusted to the distribution functions. In this study, the most frequent mean diameters are defined and calculated, and the application of the distribution functions to the experimental results is discussed. It is concluded that the Rosin‐Rammler distribution function and a modified Nukiyama‐Tanasawa function are the most suitable equations to fit the differential and the cumulative undersize distribution frequencies. This review is accompanied by calculations that illustrate the application of the equations related to this work.
Use of fertility services in Australian lesbian, bisexual and queer women’s pathways to parenthood (2020)

These findings indicate that use of fertility clinics to access donor sperm is common for LBQ women, including those with no known fertility problems, and that most women who access donor sperm conceive using IVF rather than intrauterine insemination. More needs to be known about the context and reasons for this, including factors that influence LBQ women's decision making on their pathway to parenthood.
NetTube: Exploring Social Networks for Peer-to-Peer Short Video Sharing (2009)

The recent three years have witnessed an explosion of networked video sharing, represented by YouTube, as a new killer Internet application. Their sustainable development however is severely hindered by the intrinsic limit of their client/server architecture. A shift to the peer-to-peer paradigm has been widely suggested with success already shown in live video streaming and movie-on-demand. Unfortunately, our latest measurement demonstrates that short video clips exhibit drastically different statistics, which would simply render these existing solutions suboptimal, if not entirely inapplicable. Our long-term measurement over five million YouTube videos, on the other hand, reveal interesting social networks with strong clustering among the videos, thus opening new opportunities to explore. In this paper, we present NetTube, a novel peer-to- peer assisted delivering framework that explores the clustering in social networks for short video sharing. We address a series of key design issues to realize the system, including a bi-layer overlay, an efficient indexing scheme and a pre-fetching strategy leveraging social networks. We evaluate NetTube through simulations and prototype experiments, which show that it greatly reduces the server workload, improves the playback quality and scales well.
Gaseous Ion Recombination. V (1968)

Pitaevski's formulation of the three-body ion-electron recombination rate constant based on the Fokker-Planck equation is modified so as to apply to the termolecular association of gaseous ions. The theory is expected to be valid when the collisional energy changes are small compared to the kinetic energy of the recombining ions, which occurs when the mass of the neutral is much less than the masses of the ions. The calculated and measured rate constants for such systems are in substantial agreement.
A Survey of Sketch Based Modeling Systems (2014)

3D modeling is an intricate and laboriously process which requires considerable investment of time to master. Researchers have long pondered on creating systems that would automate the steps followed by skilled 3D artists to generate detailed and realistic 3D models. Sketch Based Modeling (SBM) is a very broad area within the field of Computer Science spanning several sub-fields such as Computational Geometry, 3D Shape Retrieval, Computer Vision, Computer Graphics, and Object Oriented Programming to name a few. The interpretation of sketches to assist artists to create 3D models serves as the main idea behind efficient SBM systems. In this paper we have reviewed and analyzed recent and salient state-of-art techniques in Sketch Based Modeling. We have provided a classification of these techniques and pointed out their advantages and disadvantages.
A new form of DOS attack in a cloud and its avoidance mechanism (2010)

Data center networks are typically grossly under-provisioned. This is not a problem in a corporate data center, but it could be a problem in a shared infrastructure, such as a co-location facility or a cloud infrastructure. If an application is deployed in such an infrastructure, the application owners need to take into account the infrastructure limitations. They need to build in counter-measures to ensure that the application is secure and it meets its performance requirements. In this paper, we describe a new form of DOS attack, which exploits the network under-provisioning in a cloud infrastructure. We have verified that such an attack could be carried out in practice in one cloud infrastructure. We also describe a mechanism to detect and avoid this new form of attack.
러시아어 등위접속 연구: 동반구문과 и접속 및 제로접속과의 비교를 중심으로 (2012)

The study investigates the relationship among the zero strategy, and strategy and with strategy which are realized syntactically through enumeration of items, i coordinaton and comitative construction. It tried to show their complementary distribution, semantic and pragmatic characteristics based on syntactic peculiarities. In the case of coordination of two arguments, comitative constructions and i coordination show complementary distribution. In this case, i coordination has two properties - equivalence and independence, in the meanwhile comitative constructions have other two opposite properties - inequivalence, and dependence. Sometimes, according to the semantic characteristics of the situations or actions, the selection between i coordination and comitative constructions. In the case of coordination of two and/or arguments, i coordinations and enumeration show complementary distribution. i coordination has an exhaustive reading which compose closed set of arguments, in the meanwhile enumeration composes open set and imply that the speech has not been completed by speaker and more items can be added to the list. In i coordination, the last argument right before conjunction i is usually the least salient one in speaker`s cognition in that it comes into his head, and activates for the last time.
Bio-inspired variable structural color materials (2012)

Natural structural color materials, especially those that can undergo reversible changes, are attracting increasing interest in a wide variety of research fields. Inspired by the natural creatures, many elaborately nanostructured photonic materials with variable structural colors were developed. These materials have found important applications in switches, display devices, sensors, and so on. In this critical review, we will provide up-to-date research concerning the natural and bio-inspired photonic materials with variable structural colors. After introducing the variable structural colors in natural creatures, we will focus on the studies of artificial variable structural color photonic materials, including their bio-inspired designs, fabrications and applications. The prospects for the future development of these fantastic variable structural color materials will also be presented. We believe this review will promote the communications among biology, bionics, chemistry, optical physics, and material science (196 references).
Soy Protein with or Without Isoflavones, Soy Germ and Soy Germ Extract, and Daidzein Lessen Plasma Cholesterol Levels in Golden Syrian Hamsters (2003)

Dietary isolated soy protein (ISP, containing approximately equal amounts of daidzein and genistein), ethanol-extracted ISP (ISP (-)), soygerm or soygerm extract (containing large amounts of daidzein and glycitein and little genistein) and the isoflavone, daidzein, were hypothesized to lessen plasma cholesterol in comparison with casein. Sixty male and 60 female golden Syrian hamsters (6-8 weeks of age) were randomly assigned to six treatments fed for 10 weeks. Four of the experimental diets (ISP, daidzein, soygerm, and soygerm extract) contained 1.3 mmol total isoflavones/kg. The ISP (-) diet contained 0.013 mmol isoflavone/kg, whereas the casein diet contained no isoflavones. Hamsters fed ISP, ISP (-), daidzein, soygerm, and soygerm extract had significantly less plasma total cholesterol (by 16%-28%), less non-HDL cholesterol (by 15%-50%) and less non-HDL/HDL cholesterol ratios compared with hamsters fed casein (P < 0.01). For male hamsters, there were no differences among treatments in plasma HDL concentrations. Female hamsters fed ISP (-) had significantly greater HDL levels (P < 0.01) than females fed casein or daidzein. Triglyceride concentration was significantly less in hamsters fed ISP (-) compared with the casein-fed females. Because soy protein with or without isoflavones, soygerm and soygerm extract, and daidzein lessened plasma cholesterol to an approximately equal extent, soy protein alone, varying mixtures of isoflavones, and other extractable components of soy are responsible for cholesterol-lessening effects of soy foods, mainly due to their effects to lessen LDL cholesterol.
<title>Microfluidics using the surface tension force in microscale</title> (2000)

This review summarizes our on-going effort to establish surface tension as a useful force for MEMS, especially microfluidics. Presented are several examples of using surface tension for microdevices. Droplet ejection mechanism using bubble check valve, pumping with sequential bubbles in microchannel, and electrostatic switching of liquid-metal droplet demonstrate how surface tension attenuates liquid movement so effectively in microscale. Liquid pumping using a bubble (or a droplet) under thermal gradient and electrically driving liquid-metal droplets in microchannel demonstrate that surface tension can even be used an an attractive driving force for microactuation.
A Resonant Generator with Non-Linear Compliance for Energy Harvesting in High Vibrational Environments (2007)

This paper considers a resonant generator (RG) powered by ambient vibrations, in an environment where the level of vibration is significant. The target application of the RG is to provide power for wireless sensor nodes performing structural health monitoring. The RG is of moving magnet design and optimisation of the magnetic circuit to maximise power density has resulted in a RG with significant reluctance forces. These reluctance forces sum with the mechanical compliance to produce an overall non-linear compliance response, as a result the resonant behavior of the RG differs considerably from a simple second-order model. The approach taken to design has been experimental in nature. Results of a simulated RG are presented along with the realisation and testing of a prototype RG.
Extended group communication algorithm for updating distributed programs (2002)

Large-scale distributed systems are not always stable because the environments and the user requirements are changeable. The author has discussed the receptive platform to make distributed systems flexible and reliable. In order to achieve the receptive platform, it is essential to discuss how to update the distributed programs. Since conventional updating methods require that multiple processes be suspended simultaneously, the availability of the system becomes lower. A new method called the dynamic updating has been proposed. The key idea is that multiple versions of processes are allowed to co-exist temporarily while the old-version processes are not used anymore. If such protocol errors as the unspecified receptions and the dead-locks caused by the co-existence occurs, the suspended old-version processes are restarted from the consistent state. An algorithm, has been designed for treating the unspecified receptions. This paper proposes an extended group communication algorithm that can detect and resolve the deadlocks. By using the algorithm, the dynamic updating can be applied to more general distributed application programs.
Renal transplant care in the home. (1997)

As transplantation continues to grow as a medical field, shorter hospital stays have become the norm for transplant recipients. From the pretransplant visit to life after surgery, patients need nursing staff who have both transplant care clinical skills and teaching ability. Pretransplant home intervention allows staff to assess and educate transplant recipients much earlier in the patient's disease process. A well-educated home care team ensures continuity and quality of care for transplant recipients.
Industrial applications of automatic manipulation of flexible materials (2002)

Flexible materials are used extensively in a wide range of industrial applications including the manufacture and assembly of garment and footwear products, the packaging industry and aircraft manufacturing. These applications are often extremely labour intensive requiring fast and accurate manipulation of materials by skilled human operators. This has resulted in numerous international research and development efforts to automate certain handling and manipulation processes involving flexible materials. Much of the research has been inspired by real industrial problems, and thus has been mainly sponsored by industry. A variety of innovative techniques and methods have emerged either addressing specific industrial problems, or suggesting a number of generic solutions. This paper closely examines the international research effort of automatic manipulation of flexible materials through a classification of workpieces in terms of their broad geometric shape, industrial applications, and individual processes.

Effects of temperature, metabolic inhibitors and some other factors on fluid-phase and adsorptive pinocytosis by rat peritoneal macrophages (1979)

Low temperature, NaF and 2,4-dinitrophenol could each abolish the pinocytic uptake of 125I-labelled poly(vinylpyrrolidone) or colloidal [198Au]gold by rat peritoneal macrophages cultured in vitro. Cytochalasin B caused only partial inhibition, even at 10 microgram/ml, and colchicine (10 or 25 microgram/ml) inhibited uptake of colloidal [198Au]gold much more than that of 125I-labelled poly(vinylpyrrolidone). Dibutyryl cyclic AMP and ouabain were without effect on uptake of 125I-labelled poly(vinylpyrrolidone), and slight stimulation was seen with ATP and theophylline. Uptake of 125I-labelled poly(vinylpyrrolidone) was abolished by EGTA (5mM), but restored by adding CaCl2 (5mM). The results appear not to support the conventional criteria for the division of pinocytic phenomena into macropinocytosis, requiring a metabolic energy supply and cytoskeletal components, and micropinocytosis, requiring neither.
The Value of Accounting for Value (2014)

This is a book review for Accounting for Value. The book draws upon “Ten Commandments” instead of boring accounting jargon. Its unique value is based on renewed valuation formula to interpret the usefulness of fundamental accounting information that is consistent with historical cost accounting.
