Cross-Layer Optimization Using MIMO System for Wireless Networks (2009)

Multimedia transmissions over wireless networks need continuous media play out. In order to meet best Quality of Services, higher layers data depend on lower layer parameters. That is readily known as cross-layer design. Our cross-layer design model optimizes the physical layer, MAC layer and application layer. Video summary frames are transmitted via MIMO transmit/receive diversity with AMC at the physical layer and Payload and data rate adaptation at the MAC link layer and source coding at the application layer. We, first model the finite-state Markov chain (FSMC) for the physical layer service and based on that, we then characterize the Lagrangian relaxation and Dynamic programming to find the optimal shortest path. The source coding as well as retransmission requests are based on the channel-state information (CSI) and the system controller is implemented in all the three physical, MAC layer and application layers. The numerical results revealed that our proposed cross-layer design can efficiently achieve the effective throughput and distortion gain.
Constructing an Object-Oriented Architecture for Web Application Testing (2002)

The variety of existing web application frameworks has lead to the development of a wide range of Web applications for both the Internet and intranets. Web applications are constructed based on various frameworks ranging from simple HTML-based forms to complicated distributed-object computations based on Java and CORBA. Web software enables programmers to choose a proper framework for their own Web applications. The prevalence of Web-based applications has also led to the need to adapt software testing frameworks and tools for them. This study presents a software testing architecture that integrates several common but enhanced testing tools as a sub-architecture to fit a common Web application framework. The architecture reuses several software patterns and architectures from traditional testing environments. A Web application testing environment prototype is also constructed to demonstrate the feasibility of the proposed architecture.
Increased epigenetic age and granulocyte counts in the blood of Parkinson's disease patients (2015)

It has been a long standing hypothesis that blood tissue of PD Parkinson's disease (PD) patients may exhibit signs of accelerated aging. Here we use DNA methylation based biomarkers of aging ("epigenetic clock") to assess the aging rate of blood in two ethnically distinct case-control data sets. Using n=508 Caucasian and n=84 Hispanic blood samples, we assess a) the intrinsic epigenetic age acceleration of blood (IEAA), which is independent of blood cell counts, and b) the extrinsic epigenetic age acceleration rate of blood (EEAA) which is associated with age dependent changes in blood cell counts. Blood of PD subjects exhibits increased age acceleration according to both IEAA (p=0.019) and EEAA (p=6.1 x 10(-3)). We find striking differences in imputed blood cell counts between PD cases and controls. Compared to control subjects, PD subjects contains more granulocytes (p=1.0 x 10(-9) in Caucasians, p=0.00066 in Hispanics) but fewer T helper cells (p=1.4 x 10(-6) in Caucasians, p=0.0024 in Hispanics) and fewer B cells (p=1.6 x 10(-5) in Caucasians, p=4.5 x 10(-5) in Hispanics). Overall, this study shows that the epigenetic age of the immune system is significantly increased in PD patients and that granulocytes play a significant role.
Focus on land seismic technology: The near-surface challenge (2012)

A new era in land seismic is at hand. Growing energy demand will spur greater efforts in exploration and development into regions of the world where hydrocarbons occur in land environments. Interpreters will require accurate near-surface solutions for mapping low-relief structures and stratigraphic traps, and to improve data quality for placing horizontal wells. This will require solutions to near-surface challenges, such as energy penetration, scattering, source-generated noise, surface-generated multiples, statics, and source and receiver coupling. Solutions to these problems will become possible due to advances in seismic acquisition, including simultaneous source acquisition and wireless seismic-driven ultrahigh channel systems. Additionally, advances in seismic processing technology for processing the resulting huge data volumes will be made possible by continual growth in computational capability. These advances will for the first time allow acquisition of true 3D seismic data. This will not only result in better imaging of the subsurface, but also will allow the near surface to be addressed as an imaging problem with better description of velocities and suppression of surface-related noise.
A<i>Chlamydia trachomatis</i>-Specific Th2 Clone Does Not Provide Protection against a Genital Infection and Displays Reduced Trafficking to the Infected Genital Mucosa (2002)

A T helper type 1 (Th1) response is essential for resolving genital infections with the mouse pneumonitis biovar of Chlamydia trachomatis (MoPn). However, T-cell-dependent anti-chlamydial antibody is produced and may also contribute to protective immunity. We produced a MoPn-specific CD4 Th2 clone (Th2-MoPn) to study the role of a Th2 response during infection. We found that Th2-MoPn was unable to eradicate chlamydiae from the genital tract (GT) when it was transferred into MoPn-infected nude mice. Mice that received Th2-MoPn produced greater titers of MoPn-specific serum immunoglobulin G (IgG) antibody than mice that received a MoPn-specific Th1 clone (Th1-MoPn) (log(10) titers, 1.89 +/- 0.84 and 0.58 +/- 0.76 [mean +/- standard deviation], respectively [P < 0.01]). Also, the IgG isotypes were different for the two groups; whereas IgG1 was associated with Th2-MoPn, IgG2a was associated with Th1-MoPn. Also, infected nude mice that received Th2-MoPn produced higher levels of IgA in vaginal secretions. Although clone Th2-MoPn was detected in the GT, it was less efficient at migrating (112 +/- 35.6 labeled Th2 clone cells/10(5) GT cells) than Th1-MoPn (505 +/- 51.6 Th1 clone cells/10(5) GT cells) (P < 0.001, as determined by a t test). This may have been due to reduced expression of alpha4beta7 and P-selectin ligand 1 on Th2-MoPn. However, Th2-MoPn cells were retained in the GT during chronic infection and comprised 10 to 15% of the total GT cells 80 days after transfer. The data show that the MoPn-specific Th2 cells are important for serum and vaginal antibody production and may accumulate in the GT during chronic infection.
Well Placement Optimisation and Risking using 3-D Stochastic Reservoir Modelling Techniques (1996)

Abstract The cost-effective development of small fields requires a thorough description and evaluation of the reservoir, with a strong focus on the estimation of associated uncertainty. This paper describes a new, integrated methodology for defining and risking optimum high-angle development wells as applied to a UKSNS basin-margin gas reservoir. Sequential Indicator Simulation (SIS) realisations of genetic unit distributions were generated for each target reservoir zone, conditioned with relevant geological data derived from the reservoir and the analogue outcrop. The models were "pin-cushioned" with a large variety of well trajectories that varied in terms of inclination, azimuth, length and position within the zone. Genetic unit strings are then extracted from each well trajectory and analysed statistically, resulting in ranked well trajectories. This integrated approach produces ranked and risked well planning options, on which risk-conscious management decisions are readily made. Introduction Development decisions are increasingly taken with less data, and the use of minimal facilities requires that optimisation of development wells is more critical than formerly. The planning of development wells in complex reservoir sequences necessitates the detailed integration of data to rank potential well locations and trajectories. Utilisation of hybrid deterministic-stochastic reservoir models, enables this process to be carried out efficiently, with quantification of associated risk. The benefit of optimising the placement of high angle wells is that the risk associated with well placement is minimised and that the maximum volume of the reservoir can be accessed with the least number of wells, which in turn is highly cost effective. The methodology of this study is outlined in Fig. 1. Detailed quantification of the controls on well performance within the reservoir was followed by the definition of the appropriate genetic units. In parallel, a period of sourcing and appraisal of possible outcrop analogues was followed by a detailed outcrop study which resulted in the derivation of quantitative data of the analogue with relevance to the Frobisher reservoir. Integration of the reservoir specific and outcrop analogue data into a hybrid deterministic-stochastic model provided the basis for determination of the optimum well trajectories and subsequent risking of their success in penetrating pay. This paper will only briefly introduce the geological analyses of the reservoir and the outcrop analogue but will focus in detail on the generation of the reservoir model and on the determination and risking of the optimum well trajectories.
Cache-afﬁnity scheduling for fine grain multithreading (2002)

Cache utilisation is often very poor in multithreaded applications, due to the loss of data access locality incurred by frequent context switching. This problem is compounded on shared memory multiprocessors when dynamic load balancing is introduced and thread migration disrupts cache content. In this paper, we present a technique, which we refer to as ‘batching’, for reducing the negative impact of fine grain multithreading on cache performance. Prototype schedulers running on uniprocessors and shared memory multiprocessors are described, and finally experimental results which illustrate the improvements observed after applying our techniques are presented.
Magic Formula Tyre Model with Transient Properties (1996)

ABSTRACT The tyre force and moment generating properties connected with the vehicle's horizontal motions are considered. Knowledge of tyre properties is necessary to properly design vehicle components and advanced control systems. For this purpose, mathematical models of the tyre are being used in vehicle simulation models. The steady-state empirical ‘Magic Formula tyre model’ is discussed. The aligning torque description is based on the concepts of pneumatic trail and residual torque. This facilitates its combined slip description. Following Michelin, weighting functions have been introduced to model the combined slip force generation. A full set of equations of the steady-state part of the model of the new version ‘Delft Tyre 97’ is presented. The non-steady state behaviour of the tyre is of importance in rapid transient maneuvres, when cornering on uneven roads and for the analysis of oscillatory braking and steering properties. A relatively simple model for longitudinal and lateral transient responses restricted to relatively low time and path frequencies is introduced.

Synergistic anticancer activity of curcumin and catechin: An in vitro study using human cancer cell lines (2011)

The most practical approach to reduce morbidity and mortality of cancer is to delay the process of carcinogenesis by usage of anticancer agents. This necessitates that safer compounds are to be critically examined for anticancer activity especially, those derived from natural sources. A spice commonly found in India and the surrounding regions, is turmeric, derived from the rhizome of Curcuma longa and the major active component is a phytochemical termed curcumin. Green tea is one of the most popular beverages used worldwide, produced from the leaves of evergreen plant Camellia sinensis and the major active ingredients are polyphenolic compounds known as catechins. In this study, synergistic anticancer activity of curcumin and catechin was evaluated in human colon adenocarcinoma HCT 15, HCT 116, and human larynx carcinoma Hep G-2 cell lines. Although, both curcumin or catechin inhibited the growth of above cell lines, interestingly, in combination of both these compounds highest level of growth control was observed. The anticancer activity shown is due to cytotoxicity, nuclear fragmentation as well as condensation, and DNA fragmentation associated with the appearance of apoptosis. These results suggest that curcumin and catechin in combination can inhibit the proliferation of HCT 15, HCT 116, as well as Hep G-2 cells efficiently through induction of apoptosis.
Evaluation of Attachment of<i>Cryptosporidium parvum</i>and<i>Giardia lamblia</i>to Soil Particles (2003)

Transport of Cryptosporidium parvum oocysts and Giardia lamblia cysts in the aquatic environment is poorly understood. Information about their transport is essential for actual risk assessment and development of effective control practices. Several studies have suggested that attachment to soil particles is not likely to occur, but the hypothesis has not been well tested, partly because enumeration of C. parvum oocysts or G. lamblia cysts [written as (oo)cysts] in the presence of soil has been difficult. In this paper, a combination of flow cytometry, and epifluorescence and confocal microscopy was successfully used to enumerate (oo)cysts in the presence of soil and determine whether (oo)cysts travel freely in water or attached to soil particles. The maximum soil concentration in water samples for reliable enumeration of (oo)cysts was 2 mg/L. Particle attachment experiments detected attached pairs of oppositely charged beads and (oo)cysts, while no attachment was observed between like charged beads, (oo)cysts, and soil particles. These results support the hypothesis that electrostatic forces govern the interaction between (oo)cysts and soil particles. Batch experiments further confirmed the null hypothesis (p > 0.05) that (oo)cysts do not attach to natural soil particles. These findings suggest that, when (oo)cysts have been entrained in overland flow (i.e., runoff), they will travel freely in the water and not as part of the particulate sediment load.
Arrays of SOI photonic wire biosensors for label-free molecular detection (2010)

We present an SOI biosensor microarray chip that allows multiple molecular binding reactions to be simultaneously monitored. The individual biosensors are formed using 0.26 × 0.45 μm<sup>2</sup> silicon photonic wire waveguides, which are arranged in compact Mach-Zehnder interferometer geometries with near temperature independent response. The sharp bend radius permitted by the photonic wires is exploited to form dense spiral waveguide structures that provide several millimeters of path length in a compact 130 μm diameter circular area. This design provides the high sensitivity of a long waveguide, while maintaining compatibility with commercial microarray spotting tools. For low volume analyte delivery the sensor array chip contains a monolithically integrated microfluidic channel formed in an SU-8 overlayer. Multiple antibody-antigen reactions are observed in real-time by using an infrared camera to monitor the optical powers emerging from the sensor array output waveguides.
청소년이 지각한 부와 모의 부정적 양육태도와 학교부적응과의 관계에서 내적통제성의 조절효과 (2018)

The purpose of this study was to examine the moderating effect of internal control on the relationship between adolescents’ perceived wealth and their mothers’ negative parenting attitudes and school maladjustment. The subjects of the study were 220 middle school students in D city. The data analysis method used was t-test, Pearson’s simple correlation analysis, and multiple regression analysis using SPSS 21.0. The results were as follows: First, we found a correlation between the adolescents’ perceived wealth and their mothers’ negative parenting attitudes, school maladjustment, and internal control; second, we confirmed the moderating effect of internal control in the relationship between the adolescents’ perceived wealth and their mothers’ negative parenting attitudes and school maladjustment. These results suggest that adolescents need an appropriate counseling program to improve their internal control in order to prevent school maladjustment due to negative parenting attitudes. Finally, as this study was conducted on middle school students in D city, the results are limited in generalization to the wider population. Therefore, further research is needed to overcome these limitations.
Determination of Urinary Oxalate With Disposable Oxalate Oxidase Hembrane Strips (1989)

Abstract We describe in this paper a simple and easy method of entrapping oxalate oxidase and peroxidase in acrylamide membrane and demonstrate the use of such enzyme membrane strips in the rapid determination of urinary oxalate. A crude preparation of 45-60% acetone cut obtained from banana fruit peel (Musa paradisiaca; French plantain) homogenate serves as a source of oxalate oxidase, which decomposes oxalate into CO2 and H2O2. the oxalate content of a given urine sample is determined by introducing a small enzyme membrane strip (1 × 1 cm) into an aliquot of buffered urine containing a suitable chromogen for peroxidase and then measuring the colour developed due to the interaction of peroxidase with the newly formed H2O2 and the chromogen. Urine samples are pretreated with sodium nitrite to eliminate the interference of ascorbic acid in the assay. the enzyme membrane assay compares well with that of wet enzyme assay of oxalate in sensitivity and reliability.
Packet loss concealment in baseline JPEG coded images (2002)

Loss of coded data can affect a JPEG decoded image to a large extent, making concealment of errors caused by data loss an important issue. Reconstruction of JPEG coded images in an error-prone channel environment is investigated in this paper. First a method for estimating the missing DC coefficients of a JPEG coded image which is required for decoding the compressed image, is suggested and evaluated. As the effects of errors in estimating the missing DC value will appear as stripes across the image, a post-processing technique for removing such stripes is then developed. Finally the missing data is reconstructed by exploiting the correlation between adjacent blocks. A novel reconstruction technique which has a good performance in reconstruction of edges is proposed. A key contribution of our work is that, unlike in previously published reconstruction algorithms, differential encoding of the DC coefficients is assumed. Simulation results indicate that the performance of our algorithm is very good, even when many packets are lost during transmission of the JPEG coded image.
Dealing with workflow change: identification of issues and solutions (2000)

Adaptability has become one of the major research topics in the area of workflow management. Today’s workflow management systems have problems dealing with both momentary changes and evolutionary changes. As a result, the workflow management system is not used to support dynamically changing workflow processes or the workflow process is supported in a rigid manner, i.e. changes are not allowed or handled outside of the workflow management system. In this paper we focus on the potential problems caused by changes. To structure these problems we use a partitioning based on five perspectives. Errors resulting from change limited to one of these perspectives and multiple-perspective errors are distinguished. To clearly identify the potential problems caused by change, we distinguish between transient and incessant errors, and syntactic and semantic errors. Based on a classification of change and potential errors we point out stepping stones for solving some of the problems.
Diffractive optical elements in FLIR (1991)

In forward looking infrared (FLIR), to save volume and weight, it would be interesting to replace a doublet by a hybrid lens which is a refractive lens with a surface diffractive element engraved on one of its faces. A diffractive/refractive zinc sulfide doublet and a zinc selenide hybrid lens have been realized by diamond turning. MTFs and diffraction efficiencies close to the theory have been measured. >
An Evaluation of the Calder Hall Type of Nuclear Power Plant (1957)

The preliminary design of a nataral U, graphitemoderated, CO/sub 2/- cooled reactor and power plant similar to, but larger than, the British Calder Hall plant, with a net electrical output of 130 MWE is presented. The design is conventional, consisting mostly of standard components, the only major uncertainty being the performance of the fuel cladding. A construction cost of million and a power cost of 17 mils/kwh are estimated for this plant, assuming private utility operation in the United States, which is about three times the cost of power from conventional plants. Power output and cost for various conditions of temperatare and pressure and for increased reactor size are calculated. It is estimated that a similar plant of 740 MWE output would produce power at a cost of 10 mils/kwh. Use of He as coolant is investigated and found to offer no advantage over CO/sub 2/. (auth)
Training a confidence measure for a reading tutor that listens (2003)

One issue in a Reading Tutor that listens is to determine which words the student read correctly. We describe a confidence measure that uses a variety of features to estimate the probability that a word was read correctly. We trained two decision tree classifiers. The first classifier tries to fix insertion and substitution errors made by the speech decoder, while the second classifier tries to fix deletion errors. By applying the two classifiers together, we achieved a relative reduction in false alarm rate by 25.89% while holding the miscue detection rate constant.
