General Formulation of Laplacian Transfer Across Irregular Surfaces (1994)

We describe a simple way to study the response of an irregular resistive interface to a Laplacian field. Using this method, one can find the response of an arbitrary electrochemical electrode from its geometry alone. The same method applies to the study of the steady-state transfer across irregular membranes with finite permeability.
Extending an Instant Messaging System with Data Services and Mashups Thereof (2014)

Instant messaging systems such as ICQ and Wechat enable interpersonal and pervasive interaction via the communication networks as well as the Internet. Using the same architecture and principles, a specific system called IMAS was developed for trading exhibitions. IMAS supports Android environments, helps to establish and maintain business links, and mediates requirements of visitors and offers of exhibitors. Both visitors and exhibitors can benefit more from the system if they can not only establish contacts and make schedules with each other, but also use and mashup further information services that are provided by the backend systems of different exhibitors. This paper reports on our efforts to extend IMAS with data services and mashups thereof, presents some intermediate progress, and discusses some hard issues encountered during the extension.
Optical Probe Detection of High-Frequency Surface Acoustic Waves Generated by Phase Velocity Scanning of Laser Interference Fringes (1994)

Laser-generated high-frequency surface acoustic waves (SAWs) and their optical detection for noncontact and nondestructive materials evaluation were presented. Scanning interference fringes (SIF) produced by intersecting two coherent pulsed laser beams on a tested object with different frequencies were used as a thermoelastic source to generate a 110 MHz SAW. The SAW was detected by the optical knife edge method using another continuous wave (CW) laser as a probe beam. Estimation of the SAW amplitude was carried out and the amplitude enhancement effect of the phase velocity scanning (PVS) method was verified. As a result, the SAW amplitude of 1.4 nm was obtained on an aluminum specimen with 0.71 MW/cm 2 power density of second-harmonic waves (532 nm) of a Q-switched Nd:YAG laser. An application to anisotropic SAW velocity measurement on a silicon (100) surface was carried out.
Challenges and opportunities for adsorption-based CO<sub>2</sub> capture from natural gas combined cycle emissions (2019)

In recent years, the power sector has shown a growing reliance on natural gas, a cleaner-burning fuel than coal that emits approximately half as much CO<sub>2</sub> per kWh of energy produced. This rapid growth in the consumption of natural gas has led to increased CO<sub>2</sub> emissions from gas-fired power plants. To limit the contribution of fossil fuel combustion to atmospheric CO<sub>2</sub> levels, carbon capture and sequestration has been proposed as a potential emission mitigation strategy. However, despite extensive exploration of solid adsorbents for CO<sub>2</sub> capture, few studies have examined the performance of adsorbents in post-combustion capture processes specific to natural gas flue emissions. In this perspective, we emphasize the importance of considering gas-fired power plants alongside coal-fired plants in future analyses of carbon capture materials. We address specific challenges and opportunities related to adsorptive carbon capture from the emissions of gas-fired plants and discuss several promising candidate materials. Finally, we suggest experiments to determine the viability of new CO<sub>2</sub> capture materials for this separation. This broadening in the scope of current carbon capture research is urgently needed to accelerate the deployment of transformational carbon capture technologies.

Models of tone for tonal and non-tonal languages (2013)

Conventional wisdom in automatic speech recognition asserts that pitch information is not helpful in building speech recognizers for non-tonal languages and contributes only modestly to performance in speech recognizers for tonal languages. To maintain consistency between different systems, pitch is therefore often ignored, trading the slight performance benefits for greater system uniformity/ simplicity. In this paper, we report results that challenge this conventional approach. We present new models of tone that deliver consistent performance improvements for tonal languages (Cantonese, Vietnamese) and even modest improvements for non-tonal languages. Using neural networks for feature integration and fusion, these models achieve significant gains throughout, and provide us with system uniformity and standardization across all languages, tonal and non-tonal.
Adefovir and Tenofovir Susceptibilities of HIV-1 After 24 to 48 Weeks of Adefovir Dipivoxil Therapy: Genotypic and Phenotypic Analyses of Study GS-96-408 (2001)

HIV RT changes that arose during ADV therapy appear attributable to the patient's background ART. ADV therapy may have influenced the pattern of ZDV-associated resistance mutations that developed, but this did not result in an observed loss of viral load suppression. There was a trend toward decreased phenotypic susceptibility to adefovir in ADV-treated patients, with 4 of 16 analyzed patients showing mild, but significantly decreased susceptibility associated with the additional ZDV-associated mutations. Decreased susceptibility to the related nucleotide analog, tenofovir, was not observed to develop in ADV-treated patients.

The Impact of Sector and Market Variance on Individual Equity Variance (2009)

This paper investigates how changes in measures of sector and market variance affect equity variance by examining forecasts of equity variance over 1, 5, and 22 day time horizons. These forecasts were generated using heterogeneous autoregressive regressions that included measures of sector and market variance. The results demonstrate that sector and market variance both play an important role in determining equity variance. Further, the inclusion of measures of sector and market variance improves goodness of fit and decreases forecasting errors. These results imply that the inclusion of these measures could improve predictive models of equity variance.
C-Reactive Protein Levels in Chronic Congestive Heart Failure (2004)

Background: Serum concentrations of C-reactive protein (CRP) are elevated in patients with congestive heart failure (CHF). However, clinical data about the prognostic value of CRP levels in patients with chronic stable CHF are spare. We hypothesized that measurement of CRP might provide prognostic information in these patients. Methods: We measured serum levels of CRP in 72 patients with chronic CHF and left ventricular ejection fraction (LVEF) ＜50%. Major adverse cardiac events (death or hospitalization with worsening CHF) during a median follow-up period of 449 days were determined. Multivariate Cox regression analysis was performed to identify independent predictors of major adverse cardiac events. Results: The concentrations of CRP in the sample population were significantly increased with the severity of CHF. The 25 patients who had adverse events had significantly higher CRP levels (p = 0.0065) than the 47 patients who were event-free. We further divided the 72 CHF patients into tertiles on the basis of this sample, with the cutoff points for each tertile being ≤2.69, ＞ 2.69 to ≤ 5.38, and ＞5.38 mg per liter, respectively. The differences between event-free curves were insignificant between tertiles 1 and 2 but were significant between tertiles 1 and 3 and between tertiles 2 and 3 (p = 0.0048, p = 0.0103, respectively). In a multivariate analysis (n =58), left ventricular end-diastolic pressure (LVEDP) and serum levels of CRP ＞ 5.38 mg per liter were found to be independently significant predictors for major adverse cardiac events in patients with chronic CHF. The CRP levels were significantly correlated with LVEDP (r = 0.26, p = 0.048; n=58). Conclusions: These findings suggest that the levels of CRP are related to clinical outcomes and that measurement of CRP has the potential to play an important role as an adjunct for risk assessment in patients with chronic CHF.
Shore to ship converter system for energy saving and emission reduction (2011)

In the shipping industry, people are paying more attention on the emission issue of ships. A shore to ship power solution is attractive for port authorities and ship owners as it helps to reduce emissions in ports by connecting ships to the port electricity grid and turn off their diesel engines while at berth to improve air quality, reduce noise and vibrations in port areas. Besides, there are also economical benefits of shore to ship power as costs related to fossil fuel consumption increase. Because most ships operate with 60 Hz electricity whereas local grid in most parts of the world is 50 Hz, shore-to-ship power is required to transfer power between two different grid systems. Although some old technologies such as rotating motor/generator systems are capable to realize frequency conversion, the static frequency converter system has obvious advantages to serve as power supply today for its small size, high reliability, low losses and low civil work requirements. In this paper, PCS 6000, a medium voltage (MV) frequency converter, is introduced. By using the proven converter technologies, the proposed shore to ship power solution can realize the frequency conversion smoothly with power range from 4 MVA to 120 MV A. In this paper, firstly, the background of shore to ship power is introduced, including the overview of shore to ship power related regulations and standards. The technologies of shore to ship power, especially frequency converter system are investigated. The components, topologies and power control methods of the proposed MV frequency converter are presented. Finally, the features of the proposed converter are illustrated.
HLA Class I markers in Japanese patients with carbamazepine‐induced cutaneous adverse reactions (2009)

Carbamazepine (CBZ) is frequently used for treating epilepsy, but this drug causes cutaneous adverse drug reactions (cADRs) that may range from mild to severe. It is reported recently that the human leukocyte antigen HLA-B*1502 is associated with Stevens-Johnson syndrome (SJS) induced by CBZ in Han Chinese. We examined HLA class I in 15 Japanese patients who fulfilled the diagnostic criteria for CBZ-induced cADRs (mild in 10 and severe = SJS in 5). HLA-B*1518, HLA-B*5901 and HLA-C*0704 alleles showed higher relative risks (above 10.0) for severe cADRs. The haplotype (HLA-A*2402-B*5901-C*0102) had high relative risk (16.09) for severe cADRs. In patients with severe cADRs, frequencies of HLA-A*1101, HLA-A*3303, HLA-B*1501, HLA-B*4403, HLA-B*5101, HLA-B*5201, HLA-C*0702, and HLA-C*1202 alleles are relatively lower than in the Japanese population. These data may suggest that HLA-B*5901 is one of the candidate markers for CBZ-induced SJS in Japanese.
Wireless Communications D&D in the Science and Technology Policy in Japan (2002)

In acquired ichthyosis related to HTLV-I-associated myelopathy, histopathology revealed orthokeratotic hyperkeratosis and a perivascular inflammatory infiltrate of mononuclear lymphocytes, with areas of parakeratosis and foci of epidermotropism in rare cases. The expression profiles of K1, K10 and involucrin were similar to those in normal skin. The diffuse coexpression of K16 with K1 and K10 throughout the analysed epidermis, as well as the occurrence of restricted areas of parakeratosis expressing K6, indicate the presence of keratinocyte activation with induction of the alternative keratinization pathway, probably dependent on the cytokines liberated by the mononuclear cells of the dermal inflammatory infiltrate infected with HTLV-I. The absence of acanthosis and of increased cellular kinetics, as shown by the low rate of Ki-67 antigen expression, allow the inference that the pattern of acquired ichthyosis related to HTLV-I-associated myelopathy may be retentional. The observation of foci of parakeratosis expressing K6 in three specimens suggests that, at least in certain areas and in some cases, interference with epidermal differentiation and maturation occurs.
Use of Pressure Gauge Differentials in Well Test Quality Control and Well Performance Evaluation (1992)

Abstract Over recent years, Well Test Analysis techniques and software have developed to the stage where it is possible to match a wide range of pressure responses using one or more model solutions! However, experience in Shell Gabon has shown that the pressure correction from gauge to sandface, along the wellbore, should not be overlooked when analysing the observed gauge response. This paper examines the use of procedures, based on time synchronisation and analysis of differences between pressures measured on tandem precision pressure gauges, to assist in understanding the wellbore environment, and therefore in making this correction. Extension of the methodology to analysis of bottom hole to surface pressure differentials can also be used to better understand and optimise well performance. Specially-written software has been developed to assist in this ‘Differential Pressure Analysis’.
ORIGIN AND EARLY GROWTH OF CELERY EMBRYOIDS (1982)

SUMMARY Suspension cultures of celery embryoids were initiated by transferring portions of differentiating callus to liquid medium. Light microscope studies of the cells and embryogenic aggregates in the suspensions suggested that the embryoids arose from either single cells within the embryogenic aggregates, when the developing embryoid remained attached to the clump until the globular stage, or from free floating small groups of cells. Both types of development showed the celery embryoids to be of single cell origin. When the embryoid suspension was filtered to remove the larger embryoids and the small embryogenic aggregates and free floating embryoids were mixed with agar and plated, the development of the embryoids depended on the initial inoculum density. At low density further embryoid development was delayed while at the high inoculum density the embryoids became green and grew rapidly into torpedo embryoids with cotyledon leaves and roots. At this stage they could be transferred to a simple inorganic medium to develop into plantlets. The effect of inoculum density was thought to be due to a conditioning effect of the environment. It is suggested that the differentiating units in the embryoid suspension could be used in a cell selection procedure.
Application of alternating phase-shifting masks to 140-nm gate patterning: II. Mask design and manufacturing tolerances (1998)

In this paper we present the results of experimental patterning 140 nm poly gates with double-exposure alternating phase-shifting masks (PSM) using a Nikon EX-1 (KrF, 0.42NA) stepper. We show that: systematic intrafield line width variations can be controlled within 10 nm (3(sigma) ), interfield variations across the wafer to within 6 nm (3(sigma) ), and total variation across the wafer held to within 15 nm (3(sigma) ), with a target k<SUB>1</SUB> factor of k<SUB>1</SUB> equals 0.237 (140 nm target gate lengths). We also present the results of studies addressing several issues related to the production application of alternating PSM's, including mask manufacturing tolerances and full chip PSM design capabilities. We show that, in comparison to conventional binary masks, alternating PSM's reduce the criticality of mask line width control and reduce the sensitivity to mask defects. Furthermore tolerance to PSM phase errors can be significantly improved by placing a chrome regulator between phase-shifters. Automatic, high-speed full chip design of alternating strong PSM is now possible.
Solar power satellite (1978)

The solar power satellite (SPS) concept, under evaluation by NASA since 1974, is discussed. A typical system providing a total of 10,000 MW of electrical power to the ground receiving stations is considered. Energy conversion systems, including the photovoltaic device category using single-crystal silicon cells, are taken into account, as are the 2.45-GHz microwave power-transmission link and the ground receiver (or rectenna). Concepts involving space construction of the satellite's large structures (5 x 25 km) are described, noting that a process similar to the familiar roll-forming of light sheet metal parts has been adapted to the space environment. Transportation vehicles are discussed, including the Space Shuttle planned to reach 60 flights per year by the mid 1980's. Electrical power forecasts and advanced systems cost projections are analyzed, together with a description of costs estimates. The indirect economics of energy research and development, and the present NASA/DOE SPS program are noted.
Study on Assessing Drivers' Comprehensive Quality Based on CAN Data (2017)

Annually, there are thousands of traffic accidents casually in the world, so it is extremely important to research behavior of drivers in current days. To achieve it, we set up a platform to gather CAN data from vehicles independently. In this paper, three assessment indexes such as driving safety, riding comfort and fuel consumption of vehicles were put forward for assessing driversâ€™ comprehensive quality based on CAN data. This paper analyzed these indexes from the entropy of steering wheel angle, vehicle speed and other 7 factors. Firstly, this paper used FAHP to establish a single factor weight vector. Then the paper calculated the single factor fuzzy judgment matrix by membership functions. Finally, we assessed the driver's comprehensive quality by maximum membership. The practices proved that this model provides a simple and effective for assessing the comprehensive quality of drivers.
CD98hc (<i>SLC3A2</i>) regulation of skin homeostasis wanes with age (2013)

Skin aging is linked to reduced epidermal proliferation and general extracellular matrix atrophy. This involves factors such as the cell adhesion receptors integrins and amino acid transporters. CD98hc (SLC3A2), a heterodimeric amino acid transporter, modulates integrin signaling in vitro. We unravel CD98hc functions in vivo in skin. We report that CD98hc invalidation has no appreciable effect on cell adhesion, clearly showing that CD98hc disruption phenocopies neither CD98hc knockdown in cultured keratinocytes nor epidermal β1 integrin loss in vivo. Instead, we show that CD98hc deletion in murine epidermis results in improper skin homeostasis and epidermal wound healing. These defects resemble aged skin alterations and correlate with reduction of CD98hc expression observed in elderly mice. We also demonstrate that CD98hc absence in vivo induces defects as early as integrin-dependent Src activation. We decipher the molecular mechanisms involved in vivo by revealing a crucial role of the CD98hc/integrins/Rho guanine nucleotide exchange factor (GEF) leukemia-associated RhoGEF (LARG)/RhoA pathway in skin homeostasis. Finally, we demonstrate that the deregulation of RhoA activation in the absence of CD98hc is also a result of impaired CD98hc-dependent amino acid transports.
Towards Feature Engineering at Scale for Data from Massive Open Online Courses (2014)

We examine the process of engineering features for developing models that improve our understanding of learners' online behavior in MOOCs. Because feature engineering relies so heavily on human insight, we argue that extra effort should be made to engage the crowd for feature proposals and even their operationalization. We show two approaches where we have started to engage the crowd. We also show how features can be evaluated for their relevance in predictive accuracy. When we examined crowd-sourced features in the context of predicting stopout, not only were they nuanced, but they also considered more than one interaction mode between the learner and platform and how the learner was relatively performing. We were able to identify different influential features for stop out prediction that depended on whether a learner was in 1 of 4 cohorts defined by their level of engagement with the course discussion forum or wiki. This report is part of a compendium which considers different aspects of MOOC data science and stop out prediction.
Hypermedia method to teach concepts of colour through art (1994)

The difficulty in teaching the concepts of colour lies not so much in conveying the physical origin of colour, its possibilities and numerous applications, as in trying to find a practical means to further the understanding and the later use of the language of colour in practical applications in the fields of painting, graphic arts, advertising, fashion and decoration, etc.
