A Novel Interference Cancellation Approach for Interleaved OFDMA Uplink System (2009)

In this paper, the issue of carrier frequency offset (CFO) compensation in interleaved orthogonal frequency division multiple access (OFDMA) uplink system is investigated. To mitigate the effect of multiple access interference (MAI) caused by CFOs of different users, a new parallel interference cancellation (PIC) compensation algorithm is proposed. This scheme uses minimum mean square error (MMSE) criterion to obtain the estimation of interference users, then circular convolutions [6] are employed to restore MAI and compensate CFO. To tackle the complexity problem of circular convolutions, an efficient MAI restoration and cancellation method is developed. Simulations illustrate the good performance and low computational complexity of the proposed algorithm.
Capacity Simulation of cdma2000 1xEV-DO Forward Link With Opportunistic Beam Forming (2004)

This paper addresses possible capacity gains in a cdma2000 1/spl times/EV-DO system that utilizes the opportunistic beam forming (OBF) scheme. Contrary to the voice-oriented cdma2000 systems, where it is desirable to maintain a fixed signal-to-interference-and-noise ratio (SINK) level at the access terminal (AT), the 1/spl times/EV-DO system is designed to take advantage of the natural SINR fluctuations in a wireless channel. The resulting gain in capacity is called the "multiuser diversity gain". In certain channel conditions, the rate of the natural SINR fluctuations may not be high enough, resulting in low multiuser diversity gain. In such a case, SINR fluctuations may be induced artificially by the OBF scheme in order to increase capacity.
A Thermal Runaway Simulation on a Lithium Titanate Battery and the Battery Module (2015)

Based on the electrochemical and thermal model, a coupled electro-thermal runaway model was developed and implemented using finite element methods. The thermal decomposition reactions when the battery temperature exceeds the material decomposition temperature were embedded into the model. The temperature variations of a lithium titanate battery during a series of charge-discharge cycles under different current rates were simulated. The results of temperature and heat generation rate demonstrate that the greater the current, the faster the battery temperature is rising. Furthermore, the thermal influence of the overheated cell on surrounding batteries in the module was simulated, and the variation of temperature and heat generation during thermal runaway was obtained. It was found that the overheated cell can induce thermal runaway in other adjacent cells within 3 mm distance in the battery module if the accumulated heat is not dissipated rapidly.
Hard Decision Parallel Interference Cancellation for uplink OFDMA (2006)

In this paper, is presented bit error performance of a hard decision based parellel interference cancellation scheme for multiuser multiple carrier systems. Due to difference in carrier frequency offsets (CFO) of different users at the receiver in a orthogonal frequency division multiple access (OFDMA) system, interference from other users occurs. A hard decision based parallel interference cancellation (HDPIC) scheme is used here to reduce the effect of this interference in uplink OFDMA. CFO compensation is done in the time domain followed by DFT operations and Interference estimation and cancellation in the frequency domain. A decrease in bit error rate is shown with the application of parallel interference cancellation as compared to performance without any cancellations.
Evidence for Sodium Dodecyl Sulfate/Protein Complexes Adopting a Necklace Structure (1995)

Structural analysis by cryo-electron microscopy and small-angle X-ray scattering of ten sodium dodecyl sulfate/protein complexes in 25 mM Tris/HCl, 0.192 M glycine, pH 8.3, showed necklace-like structures of spherical micelles dispersed along the unfolded peptide chain. The micelles of most SDS/protein complexes had a constant diameter (approximately 6.2 nm), slightly larger than pure SDS micelles (approximately 5.7 nm), all micelles possessing a degree of surface roughness. The micelle-associated polypeptide is mostly situated at the interface of the sulfate head groups and hydrocarbon core, intruding into the core rather than outward from the surface. Proteins with a molecular mass less than about 20 kDa formed complexes with a single SDS micelle. Multi-micellar SDS/protein complexes had centre-to-centre intermicellar distances in the range 7.0-12.0 nm. Our findings on the constancy of micellar size, number of micelles/complex, and the relationship between the degree of occupancy of micelles and a polypeptide's molecular mass, have enabled us to speculate on the correlation between the electrophoretic mobility of a polypeptide in SDS/PAGE and its molecular mass. The anomalous electrophoretic behaviour observed for the sodium dodecyl sulfate/histone H5 complex is accounted for by the large micelle of its complex.

Automatic vs. Crowdsourced Sentiment Analysis (2014)

Due to the amount of work needed in manual sentiment analysis of written texts, techniques in automatic sentiment analysis have been widely studied. However, compared to manual sentiment analysis, the accuracy of automatic systems range only from low to medium. In this study, we solve a sentiment analysis problem by crowdsourcing. Crowdsourcing is a problem solving approach that uses the cognitive power of people to achieve specific computational goals. It is implemented through an online platform, which can either be paid or volunteer-based. We deploy crowdsourcing applications in paid and volunteer-based platforms to classify teaching evaluation comments from students. We present a comparison of the results produced by crowdsourcing, manual sentiment analysis, and an existing automatic sentiment analysis system. Our findings show that the crowdsourced sentiment analysis in both paid and volunteer-based platforms are considerably more accurate than the automatic sentiment analysis algorithm but still fail to achieve high accuracy compared to the manual method. To improve accuracy, the effect of increasing the size of the crowd could be explored in the future.
Regulation of plasma lipid transfer by the high-density lipoproteins (1988)

Mechanisms that regulate the activity of the plasma cholesteryl ester transfer protein (lipid protein transfer-I) are poorly understood. We have examined the role of endogenous regulators of the lipid transfer process, in particular the plasma high-density lipoproteins (HDLs), in both humans and two species previously reported to be devoid of cholesteryl ester transfer activity, the rat and the pig. Chromatography of d greater than 1.21 g/ml plasma on phenyl-Sepharose either enhanced (human) lipid transfer activity or unmasked (rat and pig) a nearly completely suppressed lipid transfer activity. The HDLs (either native or delipidated) were shown to be a rich source of a plasma lipid transfer inhibitor protein. Partial purification of the HDL-derived lipid transfer inhibitor protein was achieved by sequential chromatography on phenyl- and DEAE-Sepharose. Additional analysis of plasma from patients with very low (Tangier disease), normal, or very high levels of HDL cholesterol (hyperalphalipoproteinemia) revealed a significant inverse correlation between plasma cholesteryl ester transfer activity and the subjects HDL cholesterol level. These results suggest that circulating levels of the plasma high density lipoproteins may be an important determinant of plasma cholesteryl ester transfer activity, through the function of the HDL-derived lipid transfer inhibitor protein.
Data collection and analysis in the air travel planning domain (1989)

We have collected, transcribed and analyzed over 8 hours of human-human interactive problem solving dialogue in the air travel planning domain, including traveler-agent dialogues and the more constrained agent-airline dialogues. We have used this data to define and test an initial vocabulary, and to design an appropriate interface for the air travel planning domain. The initial interface design was tested via simulation, using 44 subjects solving air travel problems. Our data analysis reveals great differences between the traveler-agent interactions and the agent-airline interactions, with the traveler-simulation interactions falling somewhat in between.
The effect of weight loss on lameness in obese dogs with osteoarthritis (2010)

This paper describes the effect of weight loss on lameness in obese dogs with osteoarthritis (OA). Fourteen obese client-owned dogs with clinical and radiographic signs of OA participated in an open prospective clinical trial. After a screening visit and a visit for collection of baseline data, the dogs were fed a restricted-calorie diet over a study period of 16 weeks that incorporated six follow-up visits. At each visit, body weight and pelvic circumference were measured and severity of lameness was assessed using a numeric rating scale (NRS), a visual analogue scale (VAS) and kinetic gait analysis. This is the first study to assess both subjectively and objectively, the effect of weight loss alone on lameness in obese dogs with OA. The results indicate that body weight reduction causes a significant decrease in lameness from a weight loss of 6.10% onwards. Kinetic gait analysis supported the results from a body weight reduction of 8.85% onwards. These results confirm that weight loss should be presented as an important treatment modality to owners of obese dogs with OA and that noticeable improvement may be seen after modest weight loss in the region of 6.10 - 8.85% body weight.

The approach and findings of this model calculation are systematically presented.
A novel P2P and cloud computing hybrid architecture for multimedia streaming with QoS cost functions (2010)

Since its appearance, peer-to-peer technology has given raise to various multimedia streaming applications. Today, cloud computing offers different service models as a base for successful end user applications. In this paper we propose joining peer-to-peer and cloud computing into new architectural realization of a distributed cloud computing network for multimedia streaming, in a both centralized and peer-to-peer distributed manner. This architecture merges private and public clouds and it is intended for a commercial use, but in the same time scalable to offer the possibility of non-profitable use. In order to take advantage of the cloud paradigm and make multimedia streaming more efficient, we introduce APIs in the cloud, containing build-in functions for automatic QoS calculation, which permits negotiating QoS parameters such as bandwidth, jitter and latency, among a cloud service provider and its potential clients.

Map-Based Image Super-Resolution Reconstruction (2008)

From a set of shifted, blurred, and decimated image , super-resolution image reconstruction can get a high-resolution image. So it has become an active research branch in the field of image restoration. In general, super-resolution image restoration is an ill-posed problem. Prior knowledge about the image can be combined to make the problem well-posed, which contributes to some regularization methods. In the regularization methods at present, however, regularization parameter was selected by experience in some cases and other techniques have too heavy computation cost for computing the parameter. In this paper, we construct a new super-resolution algorithm by transforming the solving of the System stem <em>Є</em>=<em>An </em>into the solving of the equations X+A*X-1A=I , and propose an inverse iterative method.
Case-based design: A review and analysis of building design applications (1997)

Abstract This paper presents a review of CBD and its application to building design in particular. Case-based design is the application of case-based reasoning to the design process. Design maps well to case-based reasoning because designers use parts of previous design solutions in developing new design solutions. This paper identifies problems of case representation, retrieval, adaptation, presentation, and case-based maintenance along with creativity, legal, and ethical issues that need to be addressed by CBD systems. It provides a comprehensive review of CBD systems developed for building design and provides a detailed comparison of the CBD systems reviewed.
GBDE - GEOM Based Disk Encryption (2003)

The ever increasing mobility of computers has made protection of data on digital storage media an important requirement in a number of applications and situations. GBDE is a strong cryptographic facility for denying unauthorised access to data stored on a ‘‘cold’ ’ disk for decades and longer. GBDE operates on the disk(-partition) level allowing any type of file system or database to be protected. Asignificant focus has been put on the practical aspects in order to make itpossible to deploy GBDE in the real world. 1 1. Losing data left and right In the last couple of years, gentlemen of the press have repeatedly been able to expose how laptop computers containing highly sensitive or very valuable information have been lost to carelessness, theft and in some cases espionage. [THEREG] The scope of the problem is very hard to gauge, since it is not a subject which the involved persons and, in particular, institutions are at all keen on having exposed. However, a few data points have been uncovered, revealing that the U.S. Federal Bureau of Investigation loses, on average, one laptop every three days. [DOJ0227] When a computer is lost, stolen or misplaced, it is very often the case that the computer hardware represents a value which is insignificant compared to the value of the disk contents. More often than not, the only reason the press heard about it was that the material on the disk was ‘‘hot’ ’ enough to make the loss of control rattle people at government level. While it is easy to blame these incidents on ‘‘user error’’, as is generally done, doing so makes it a very hard problem to fix. Human nature being what it is, seems to remain just that. In the absence of technical counter measures, administrative measures have been applied, generally with abysmal results. In one case, a bureaucracy has handled the problem according to what could easily be
CMOS +1V to -1V, rail to rail operational amplifier (1994)

A fully differential operational amplifier operating within a 2 V power supply range is presented. The amplifier was designed using 1.2 mu m CMOS technology and uses multi-regulation techniques to provide a high open loop gain magnitude without degrading the open loop phase response. In order to overcome the limited input common mode voltage range due to the low power supply rails, fully differential complementary techniques are employed. The output voltage swing extends to be within 0.2 V of the lower and upper power supply rails. >
Development of a Hardware-in-the-loop system for testing cell balancing circuits (2013)

This paper presents the development of a Hardware-in-the-loop (HIL) system that facilitates experimental testing of cell balancing circuits by emulating energy storage components. Testing cell balancing circuits with real batteries limits the circuits to be tested under various scenarios as repetitive charging and discharging would deteriorate the life of the batteries. Furthermore, a HIL testing system allows comprehensive evaluations of any cell balancing circuits or control strategy against any cell condition with minimum resources and time.
Oxygen absorption by skin exposed to oxygen supersaturated water (2012)

The present study tests the hypothesis that skin on the plantar surface of the foot absorbs oxygen (O(2)) when immersed in water that has a high dissolved O(2) content. Healthy male and female subjects (24.2 ± 1.4 years) soaked each foot in tap water (1.7 ± 0.1 mg O(2)·L(-1); 30.7 ± 0.3 °C) or O(2)-infused water (50.2 ± 1.7 mg O(2)·L(-1); 32.1 ± 0.5 °C) for up to 30 min in 50 different experiments. Transcutaneous oximetry and near infrared spectroscopy were used to evaluate changes in skin PO(2), oxygenated haemoglobin, and cytochrome oxidase aa(3) that resulted from treatment. Compared with the tap water condition, tissue oxygenation index was 3.5% ± 1.3% higher in feet treated for 30 min with O(2)-infused water. This effect persisted after treatment, as skin PO(2) was higher in feet treated with O(2)-infused water at 2 min (237 ± 9 vs. 112 ± 5 mm HG) and 15 min (131 ± 1 vs. 87 ± 4 mm HG) post-treatment. When blood flow to the foot was occluded for 5 min, feet resting in O(2)-infused water maintained a 3-fold higher O(2) consumption rate than feet treated with tap water (9.1 ± 1.4 vs. 3.0 ± 1.0 µL·100 g(-1)·min(-1)). We estimate that skin absorbs 4.5 mL of O(2)·m(-2)·min(-1) from O(2)-infused water. Thus, skin absorbs appreciable amounts of O(2) from O(2)-infused water. This finding may prove useful and assist development of treatments targeting skin diseases with ischemic origin.
Identification of Gene and MicroRNA Signatures for Oral Cancer Developed from Oral Leukoplakia (2015)

In clinic, oral leukoplakia (OLK) may develop into oral cancer. However, the mechanism underlying this transformation is still unclear. In this work, we present a new pipeline to identify oral cancer related genes and microRNAs (miRNAs) by integrating both gene and miRNA expression profiles. In particular, we find some network modules as well as their miRNA regulators that play important roles in the development of OLK to oral cancer. Among these network modules, 91.67% of genes and 37.5% of miRNAs have been previously reported to be related to oral cancer in literature. The promising results demonstrate the effectiveness and efficiency of our proposed approach.
cGMP stimulation of stem cell proliferation (1977)

The process by which resting hemopoietic stem cells become activated is poorly understood, but it has been suggested that cyclic nucleotide levels in the cell may play an important role. In the present study, the effect of various, nucleotides and stimulators of nucleotide synthesis upon the formation of in vitro granulocyte colonies has been examined. It was found that physiologic concentrations of 3′, 5′-cyclic guanosine monophosphate enhanced the formation of granulocyte- macrophage colonies in the presence of colony-stimulating activity. The cells sensitive to cGMP activation were resistant to thymidine suicide and could not be activated by colony-stimulating activity alone. Therefore it was suggested that the cGMP sensitive stem cell was an ordinarily resting stem cell which was triggered into a proliferative state by cGMP.
Measurement of properties and function of skin (1991)

Dermatologists and skin biologists have traditionally approached the diagnosis of skin diseases by either a very gross measurement of its physical state, i.e. a skin pinch, or at the other extreme by being concerned with the cellular and sub-cellular organisation of the skin. Recently, using methods often borrowed from materials science, techniques have been developed and used to aid the investigation of the changes that occur with disease and ageing, for example. A review of these methods developed to study the structure and function of skin by the physical scientists working in close collaboration with dermatologists, pathologists and skin biologists is presented.
Photovoltaic-integrated electrochromic device for smart-window applications - preprint (2000)

Three different, innovative approaches have been taken to develop photovoltaic (PV) integrated electrochromic (EC) devices for smart-window applications. These are (1) a stand-alone, side-by-side PV-powered EC window; (2) a monolithically integrated PV-EC device; and, (3) a novel photoelectrochromic device based on dye-sensitized TiO{sub 2} solar cells. The compatibility of PV-EC devices has been analyzed and the potential for large energy savings for building applications has been suggested.
Natural products and Chagas' disease: a review of plant compounds studied for activity against Trypanosoma cruzi (2011)

Here, we review studies that have investigated the activity of plant-derived compounds against Trypanosoma cruzi, the etiologic agent of Chagas’ disease. In the last decade, more than 300 species belonging to almost 100 families have been evaluated for activity, and here we describe the compounds isolated; 85 references are cited.
