Chestnut (2012)

Graphics processing units (GPUs) are powerful devices capable of rapid parallel computation. GPU programming, however, can be quite difficult, limiting its use to experienced programmers and keeping it out of reach of a large number of potential users. We present Chestnut, a domain-specific GPU parallel programming language for parallel multidimensional grid applications. Chestnut is designed to greatly simplify the process of programming on the GPU, making GPU computing accessible to computational scientists who have little or no parallel programming experience, as well as a useful and powerful language for more experienced programmers. In addition, Chestnut has an optional GUI programming interface that makes GPU computing accessible to even novice programmers.

An efficient protocol for realizing cooperative diversity in wireless networks (2002)

We develop two variants of an energy-efficient cooperative diversity protocol that combats fading induced by multipath propagation in wireless networks, The underlying techniques build upon the classical relay channel and related work and exploit space diversity available at distributed antennas through coordinated transmission and processing by cooperating radios. While applicable to any wireless setting, these protocols are particularly attractive in ad-hoc or peer-to-peer wireless networks, in which radios are typically constrained to employ a single antenna. Substantial energy-savings resulting from these protocols can lead to reduced battery drain, longer network lifetime, and improved network performance in terms of, e.g., capacity.
Radiation-acoustic monitoring of therapeutic beam (2004)

A method of dose field control in patient's body during radiation treatment is proposed. It is based on detection of thermoacoustic pulse to be generated by pulsed radiation beam in vivo and on reconstruction of dose field characteristics by stress amplitude. A possible scheme of realization of the proposed method is considered. Typical variants of dose fields and corresponding solutions of radiation thermoacoustic equation are discussed. The values of stress pulses and accuracy of dose field location are estimated for electron, X-ray and proton beams.

The Influence of Information Technology and Systems on Managerial Performance: An Empirical Study at a Regional Bank in North Sulawesi Province (2019)

This study aims to determine the influence of information technology and systems on managerial performance in a regional bank in Indonesia. The novelty of this study lies in the relationship between information technology and managerial performance, and the research object of this study which was a regional bank which generally operating in the districts resulting from the expansion after the era of regional autonomy in Indonesia. The data of this study were collected using a questionnaire to 242 Bank Sulutgo employees as the respondents, operating in 10 cities and districts in North Sulawesi province. Structural equation model (SEM) was used to analyse the data.
Data characterizing the chloroplast genomes of extinct and endangered Hawaiian endemic mints (Lamiaceae) and their close relatives (2016)

These data are presented in support of a plastid phylogenomic analysis of the recent radiation of the Hawaiian endemic mints (Lamiaceae), and their close relatives in the genus Stachys, "The quest to resolve recent radiations: Plastid phylogenomics of extinct and endangered Hawaiian endemic mints (Lamiaceae)" [1]. Here we describe the chloroplast genome sequences for 12 mint taxa. Data presented include summaries of gene content and length for these taxa, structural comparison of the mint chloroplast genomes with published sequences from other species in the order Lamiales, and comparisons of variability among three Hawaiian taxa vs. three outgroup taxa. Finally, we provide a list of 108 primer pairs targeting the most variable regions within this group and designed specifically for amplification of DNA extracted from degraded herbarium material.
Transforming growth factor-beta 1 (TGF-β1) down-regulates IgA Fc-receptor (CD89) expression on human monocytes (1996)

IgA is the predominant immunoglobulin in human secretions and the second most important immunoglobulin in the circulation on a quantitative basis. The clearance of IgA is dependent on the function of at least three types of receptors. One of these receptors recognizes the Fc portion of the IgA molecule, Fc alpha R, which has been cloned recently. Fc alpha R, also designated CD89, is found on a number of cells, including human glomerular mesangial cells, and monocytes. In this study we analysed the effect of TGF-beta 1, a cytokine with strong immunosuppressive function, on the expression of CD89 on freshly isolated monocytes. We found that TGF-beta 1 down-regulates CD89 expression on human peripheral blood monocytes in a dose-dependent fashion. Optimal down-regulation occurred at a concentration of 5 ng/ml. The down-regulation of CD89 by TGF-beta 1 is linear in time, with a mean down-regulation of 34 +/- 13% after 24 h. Also at the mRNA level, CD89 expression was down-regulated by TGF-beta 1, suggesting regulation of CD89 at the transcriptional level. Monocytes pre-treated with TGF-beta 1 displayed a reduced response to IgA, as measured by IL-6 production by monocytes, in contrast to monocytes pre-treated with medium alone. These results suggest an important role for TGF-beta 1 in the regulation of CD89. This down-regulation may have direct consequences for the handling of IgA by human monocytes.
Direct Detection of Emergent Fungal Pathogen Candida auris in Clinical Skin Swabs by SYBR Green-Based Quantitative PCR Assay (2018)

The recent emergence of the multidrug-resistant and pathogenic yeast <i>Candida auris</i> continues to cause public health concern worldwide. <i>C. auris</i> is alarming because it causes health care-associated outbreaks and can establish invasive infections with high mortality rates. Transmission between patients is facilitated by the ability of <i>C. auris</i> to persistently colonize multiple body sites, including the skin, and survive for weeks on surfaces in health care settings. Rapid identification of colonized patients is needed to implement timely infection control measures. Currently, CDC laboratories use an enrichment culture-based approach that can take up to 2 weeks to identify <i>C. auris</i> from composite swabs from the bilateral axillae and groin. A rapid SYBR green quantitative PCR (qPCR) assay that can identify <i>C. auris</i> in a single day was recently described. In this study, we developed the SYBR green qPCR assay further by incorporating a DNA extraction procedure for skin swabs and by including an internal amplification control based on the distinguishable melt curve of a lambda DNA amplicon. The assay was conducted using 103 clinical axilla/groin skin swab samples. Using the enrichment culture-based approach as a gold standard, we determined that the SYBR green <i>C. auris</i> qPCR has a sensitivity of 0.93 and specificity of 0.96. Overall, we found that the SYBR green <i>C. auris</i> qPCR assay can be successfully applied for rapid and accurate detection of <i>C. auris</i> in patient skin swabs, thereby increasing diagnostic options for this emerging pathogen.
Herpes simplex virus mutants defective in the virion-associated shutoff of host polypeptide synthesis and exhibiting abnormal synthesis of alpha (immediate early) viral polypeptides (1983)

Six mutants isolated from herpes simplex virus type 1 were judged to be defective with respect to the virion-associated function acting to rapidly shut off host polypeptide synthesis in herpes simplex virus-infected cells. The mutants were capable of proper entry into the cells, but, unlike the parent wild-type virus, they failed to shut off host polypeptide syntehsis in the presence of actinomycin D. They were consequently designated as virion-associated host shutoff (vhs) mutants. In the presence of actinomycin D, three of the mutants, vhs1, -2, and -3, failed to shut off the host at both 34 and 39 degrees C, whereas vhs4, -5, and -6 exhibited a temperature-dependent vhs phenotype. Since the mutants were capable of growth at 34 degrees C, it appeared that the vhs function was not essential for virus replication in cultured cells. Temperature-shift experiments performed with the vhs4 mutant showed that an active vhs function was required throughout the shutoff process and that, once established, the translational shutoff could not be reversed. In the absence of actinomycin D, the mutants induced a generalized, secondary shutoff of host translation, which required the synthesis of beta (early) or gamma (late) viral polypeptide(s). The vhs mutants appeared to be defective also with respect to post-transcriptional shutoff of alpha (immediate early) viral gene expression, since (i) cells infected with mutant viruses overproduced alpha viral polypeptides, (ii) there was an increased functional stability of alpha mRNA in the vhs1 mutant virus-infected cells, and (iii) superinfection of vhs1-infected cells with wild-type virus, in the presence of actinomycin D, resulted in a more pronounced shutoff of alpha polypeptide synthesis from preformed alpha mRNA than equivalent superinfection with vhs1 virus. The data suggest that the synthesis of alpha polypeptides in wild-type virus infections is subject to a negative post-transcriptional control involving viral gene product(s) present in infected cell lysates constituting virus stocks. The vhs1 mutant and possibly other vhs mutants contain a mutation in the gene encoding this function.
Carbohydrate‐Deficient Transferrin and γ‐Glutamyltransferase as Markers of Heavy Alcohol Consumption: Gender Differences (1994)

Carbohydrate-deficient transferrin (CDT) has been described as a more specific and sensitive marker of recent heavy alcohol consumption as compared with the current tests now available, such as gamma-glutamyltransferase (GGT). Most of the data generated from European populations have not compared the utility of CDT and GGT in the detection of heavy alcohol consumption as a function of gender. We examined the ability of both CDT and GGT to discriminate between 42 men and 18 women with heavy alcohol consumption (> 60 g/day) admitted to an alcohol detoxification center and a group of controls matched for age, race, and gender. CDT was higher, but GGT lower, in control females compared with males. Both CDT and GGT were higher in patients of both genders. At specificities > 90%, the sensitivity of CDT for detecting male alcohol abusers was 79% and for female alcohol abusers 44%. For GGT, the sensitivities were 65% and 44%, respectively. When both tests were used simultaneously, the sensitivity for the detection of alcohol abusers increased to 95% for males and 72% for females. Receiver Operator Characteristic analysis tended to confirm the superiority of CDT over GGT in the detection of heavy alcohol consumption in males, but not in females. A positive relationship was found between serum iron levels and CDT in control females but in no other group. The concordant findings of this American study with those in similar French and Finnish clinical populations, utilizing similar assay techniques, suggest that the measurement of CDT is clinically more useful than GGT in detecting recent heavy alcohol consumption in males.(ABSTRACT TRUNCATED AT 250 WORDS)
The gerontogenes <i>age‐1</i> and <i>daf‐2</i> determine metabolic rate potential in aging <i>Caenorhabditis elegans</i> (1995)

Mutations in the genes age-1 and daf-2 extend life span of Caenorhabditis elegans by 100 and 200%, respectively, in axenic culture. Adult worms that are mutant in either of these genes have higher metabolic capacities, called metabolic rate potentials, at all ages and the extension of their life expectancies are positively correlated with the increases of metabolic rate potential. The activities of catalase, superoxide dismutase, isocitrate dehydrogenase, isocitrate lyase, and malate synthase are all higher relative to those in worms that are wild type for these genes, but acid phosphatase is down-regulated and alkaline phosphatase activity is lowered to 10% of the activity measured in age-1(+) and daf-2(+) worms. These results suggest that genes that regulate metabolic activity may play central roles in longevity and senescence.
Comparative study of initial growth stage in PVT growth of AlN on SiC and on native AlN substrates (2005)

The main issue in homoepitaxial growth of aluminum nitride (AlN) on native seed substrates appears to be aluminum oxynitride poisoning of seed surface leading to polycrystalline growth at 1750–1850 °C. This is well below the lowest growth temperature appropriate for physical vapor transport (PVT) of bulk AlN, which is about 2150 °C. Contrary, heteroepitaxial growth of AlN on SiC is relatively easy to achieve because of natural formation of a thin molten layer on the seed surface and VLS growth of AlN via the molten buffer layer. The most critical issue of AlN growth on SiC is cracking of the grown layer upon cooling as a result of different thermal expansion. Optimization of seeded growth process can be achieved by proper choice of SiC seed orientation and by use of ultra-pure starting material. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
Compensation Circuit for AM OLED Displays Composed of Two TFTs and One Capacitor (2007)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> In this paper, we propose the threshold-voltage compensation pixel circuit that is composed of two thin-film transistors (TFTs) and one capacitor (2T1C). It not only compensates the deviation of the threshold voltage of the driver TFT but also actualizes the large aperture ratio for organic light-emitting diode (OLED) devices as well as the traditional 2T1C circuit. We show the result of SPICE simulation for the pixel circuit; it indicates that the circuit can allocate the relatively large aperture ratio for OLED devices. </para>

Integrated multimodal optical microscopy for structural and functional imaging of engineered and natural skin (2012)

An integrated multimodal optical microscope is demonstrated for high-resolution, structural and functional imaging of engineered and natural skin. This microscope incorporates multiple imaging modalities including optical coherence (OCM), multi-photon (MPM), and fluorescence lifetime imaging microscopy (FLIM), enabling simultaneous visualization of multiple contrast sources and mechanisms from cells and tissues. Spatially co-registered OCM/MPM/FLIM images of multi-layered skin tissues are obtained, which are formed based on complementary information provided by different modalities, i.e., scattering information from OCM, molecular information from MPM, and functional cellular metabolism states from FLIM. Cellular structures in both the dermis and epidermis, especially different morphological and physiological states of keratinocytes from different epidermal layers, are revealed by mutually-validating images. In vivo imaging of human skin is also investigated, which demonstrates the potential of multimodal microscopy for in vivo investigation during engineered skin engraftment. This integrated imaging technique and microscope show the potential for investigating cellular dynamics in developing engineered skin and following in vivo grafting, which will help refine the control and culturing conditions necessary to obtain more robust and physiologically-relevant engineered skin substitutes.
Integrating low-rank and group-sparse structures for robust multi-task learning (2011)

Multi-task learning (MTL) aims at improving the generalization performance by utilizing the intrinsic relationships among multiple related tasks. A key assumption in most MTL algorithms is that all tasks are related, which, however, may not be the case in many real-world applications. In this paper, we propose a robust multi-task learning (RMTL) algorithm which learns multiple tasks simultaneously as well as identifies the irrelevant (outlier) tasks. Specifically, the proposed RMTL algorithm captures the task relationships using a low-rank structure, and simultaneously identifies the outlier tasks using a group-sparse structure. The proposed RMTL algorithm is formulated as a non-smooth convex (unconstrained) optimization problem. We propose to adopt the accelerated proximal method (APM) for solving such an optimization problem. The key component in APM is the computation of the proximal operator, which can be shown to admit an analytic solution. We also theoretically analyze the effectiveness of the RMTL algorithm. In particular, we derive a key property of the optimal solution to RMTL; moreover, based on this key property, we establish a theoretical bound for characterizing the learning performance of RMTL. Our experimental results on benchmark data sets demonstrate the effectiveness and efficiency of the proposed algorithm.
High resolution angular measurements with single vector sensors and arrays (2008)

The direction finding capability of acoustic sensors that directly measure acoustic particle velocity alone or in combination with pressure measurements (vector sensors) is well known. The angular resolution of the measurements can be improved by using arrays of vector sensors. It is also possible to improve angular resolution by additional processing of data from even a single vector sensor. This approach could be especially advantageous for sonar systems designed to operate from small platforms such as autonomous underwater vehicles. In this talk linear and non-linear methods for processing data from one or more vector sensors to achieve high angular resolution will be reviewed. Experimental investigations comparing the methods will be reported and factors found to limit the localization and detection performance of sonar systems employing the methods will be discussed.
The genetic and environmental basis of atopic diseases (2008)

The prevalence of atopic diseases has increased abruptly in recent years in most Westernized societies, making the question why this happened the topic of a heated debate. The best paradigm available to date to explain this steep rise, the 'hygiene hypothesis', supports that it is the excess 'cleanliness' of our environments that has led to the decline in the number of infectious stimuli that are necessary for the proper development of our immune system. Recent findings support that it is the combined effect that not only pathogenic, but also non-pathogenic microorganisms, and even their structural components,can exert on the immune system that deters from the development of atopic responses. Adding to these results are intriguing new findings on the effect different gene polymorphisms can have on an individual's predisposition to allergic diseases. The most important linkages produced, to date, include those among the genes for IL-4, IL-13, HLA-DRB, TNF, LTA,FCER1B, IL-4RA, ADAM33, TCR alpha/delta, PHF11, GPRA, TIM, p40, CD14, DPP10, T-bet, GATA-3, and FOXP3 and allergic disorders. The two parallel research efforts, epidemiologic and genetic, are only recently starting to converge,producing fascinating results on the effect particular gene-environment interactions might have in the development of atopy.The most important lesson learned through this tremendous research effort is that not only a small number but thousands and millions of separate risk factors act in concordance in the production of the allergic phenotype.
Chemiluminescence biosensor chip based on a microreactor using carrier air flow for determination of uric acid in human serum (2002)

A chemiluminescence biosensor on a chip coupled to a microfluidic system and a microreactor is described in this paper. The chemiluminescence biosensor measured 25 x 75 x 6.5 mm in dimension, and was readily produced in an analytical laboratory. The sol-gel method is introduced to co-immobilize horseradish peroxidase (HRP) and luminol in the microreactor, and to immobilize uricase in the enzymatic reactor. The main characteristic of the biosensor was to introduce air as the carrier flow instead of the more common solution carrier for the first time. The uric acid was determined by a chemiluminescent (CL) reaction between the hydrogen peroxide produced from the enzymatic reactor and luminol under the catalysis of HRP in the microreactor. The linear range of the uric acid concentration was 1 to 100 mg L(-1) and the detection limit was 0.1 mg L(-1) (3sigma).
