Photophysics of buckminsterfullerene and other carbon cluster ions (1988)

The laser-induced fragmentation behavior of positive carbon cluster ions has been investigated by tandem time-of-flight techniques for the jet-cooled clusters up to 80 atoms in size. Two distinct photophysical regimes were found. The first applies to clusters with 34 atoms or more, all of which dissociate to produce even numbered fragments. Large even clusters fragment by the loss of the high energy species C2, odd ones lose a C atom. The second regime applies to clusters composed of 31 or less atoms, all of which fragment by the loss of C3. These two regimes are sharply separated by C+32 which fragments to produce small cluster ions in the 10–19 atom size range. Fragmentation of the large clusters occurs on a microsecond or faster time scale only at very high levels of excitation (&gt;12.8 eV). These photophysical results are interpreted as consequences of the large even clusters having edgeless, spheroidal cage structures while the small ones have linear chain or ring structures.
The Manipulated Rotating BPSK Technique Compatible with Conventional CMA Algorithm (2015)

This paper proposes a manipulated rotating binary phase shift keying (MR-BPSK) technique, which can use conventional constant modulus algorithm (CMA) to update the adaptive filter coefficient. This technique inherits the robust nonlinear tolerance of conventional BPSK, which is proved in 420/440km real time unrepeatered transmission experiment.
EcoCyc: a comprehensive database of Escherichia coli biology (2010)

EcoCyc (http://EcoCyc.org) is a comprehensive model organism database for Escherichia coli K-12 MG1655. From the scientific literature, EcoCyc captures the functions of individual E. coli gene products; their regulation at the transcriptional, post-transcriptional and protein level; and their organization into operons, complexes and pathways. EcoCyc users can search and browse the information in multiple ways. Recent improvements to the EcoCyc Web interface include combined gene/protein pages and a Regulation Summary Diagram displaying a graphical overview of all known regulatory inputs to gene expression and protein activity. The graphical representation of signal transduction pathways has been updated, and the cellular and regulatory overviews were enhanced with new functionality. A specialized undergraduate teaching resource using EcoCyc is being developed.
Gene Therapy and Jurisprudence (2001)

Imagine parents sitting in a physician's office learning about a new treatment for their child's rare disease. The treatment is effective but costly, and is not covered by any healthcare provider. The treatment is gene therapy and as there are no previous medical options, no treatment costs were set. The third-party provider will undoubtedly resist payment, leading to disputes and, eventually, the courts.
Accuracy of fish-eye lens models (2010)

The majority of computer vision applications assumes that the camera adheres to the pinhole camera model. However, most optical systems will introduce undesirable effects. By far, the most evident of these effects is radial lensing, which is particularly noticeable in fish-eye camera systems, where the effect is relatively extreme. Several authors have developed models of fish-eye lenses that can be used to describe the fish-eye displacement. Our aim is to evaluate the accuracy of several of these models. Thus, we present a method by which the lens curve of a fish-eye camera can be extracted using well-founded assumptions and perspective methods. Several of the models from the literature are examined against this empirically derived curve.
Differential lncRNA expression profiles in recurrent gliomas compared with primary gliomas identified by microarray analysis. (2015)

Glioma, especially high-grade glioma, is highly malignant with high rate of recurrence and poor prognosis. The mechanisms of glioma progression and recurrence have not been elucidated. Previous studies showed that long non-coding RNAs (lncRNAs) involved in the development and progression of glioma. However, the roles of lncRNAs in the recurrence of glioma remain unknown. We use high throughput microarray to screen the differentially expressed lncRNAs and mRNAs in recurrence gliomas compared with primary gliomas. We found a total of 1,111 lncRNAs were differentially expressed in recurrent group. Among these, 639 lncRNAs were up-regulated, while 472 lncRNAs were down-regulated (fold Change ≥2.0). GO (Gene ontology) and pathway analysis revealed that the potential functions of differentially expressed lncRNAs were closely connected with the processes of cancer progression and pathogenesis. LncRNA classification and subgroup analysis further identified three important clusters of differentially expressed lncRNA-mRNA pairs which have potential gene regulatory functions. This study for the first time showed abundant differentially expressed lncRNAs in recurrent gliomas. Some lncRNAs may play important roles in glioma recurrence, such as previously reported H19, CRNDE, HOTAIRM1 or unreported AC016745.3, XLOC_001711, RP11-128A17.1. Moreover, this study set a basis for future researches on specific lncRNA which may contribute to the recurrence of glioma. Further studies on these lncRNAs will help to elucidate the mechanism of glioma recurrence at genetic level and find therapeutic targets for glioma patients.
Switching (overtargeting) of estrogen effects and its potential role in hormonal carcinogenesis. (2002)

Peculiarities of the estrogens influence on target tissues is one of the crucial problems in understanding of the estrogen-induced carcinogenesis and anticarcinogenesis mechanisms. Conditions or factors enhancing the genotoxic component in total effect of estrogens (on the uterine tissue, in particular) are very important, since these factors may influence both the hormonal carcinogenesis type and biological properties of the developing hormone-dependent tumors. In this study female rats (3 months of age at the beginning of experiment) have been given plain water (group 1) or 5% ethanol solution over 4 months. Rats which received ethanol were further divided into 6 groups (groups 2-7). During last 2 months of the experiment N-acetylcysteine was given to rats in group 3, ascorbic acid (vitamin C) and alpha-tocopherol (vitamin E)--to group 4, melatonin--to group 5, carnosine--to group 6; the rats in group 7 swam for 5 days a week according to the so called developing schedule. 2.5 weeks before the end of experiment all rats underwent bilateral ovariectomy, and over 11 days preceding the last day of the experiment they received injections of estradiol (2 microg intramuscularly daily). When the experiment was over, estradiol and cholesterol blood levels, progesterone receptors content, peroxidase activity, proliferation index, percent of cells in S and G2/M phases, thickness of endometrium and rate of DNA damage in uterine tissue (COMET assay) and estradiol 2-hydroxylase activity in liver tissue were measured. The conclusion was that administration of 5% ethanol combined with estrogen injections results in genotoxic (G) changes in the uterus, which may be prevented by giving N-acetylcysteine or melatonin. Combination of vitamins C and E enhances some features of hormonal (H) estrogen effects (uterine weight, induction of progesterone receptors), but attenuates the other (proliferation index). Consequently, the combination of N-acetylcysteine and optimal doses of ascorbic acid and alpha-tocopherol may be recommended for prevention of the phenomenon of switching of estrogen effects [PSEE] (e.g. enhancement of G-component and decrease of H-component), observed particularly in cases of the treatment with tobacco smoke or ethanol consumption in more than moderate (15%) concentrations, which lead to the increased risk of genotoxic type of hormonal carcinogenesis.

Fabrication and mobility characteristics of ultra-thin strained Si directly on insulator (SSDOI) MOSFETs (2004)

A tensile-strained Si layer was transferred to form an ultra-thin (<20 nm) strained Si directly on insulator (SSDOI) structure. MOSFETs were fabricated, and for the first time, electron and hole mobility enhancements were demonstrated on strained Si directly on insulator structures with no SiGe layer present under the strained Si channel.
Fat-saturation MR imaging of the upper abdomen. (1990)

The fat-saturation (fatsat) MR technique decreases the signal intensity of fat, thereby enhancing the definition of upper abdominal organs and reducing artifacts while maintaining the T1 and T2 information available on spin-echo sequences. To evaluate the potential of fatsat in examining the abdomen, we conducted a prospective study involving 30 subjects, including four normal volunteers, 18 patients investigated for liver disease, and eight patients studied for miscellaneous abdominal disease. Short TR, 300-600/15-20 (TR/TE), and long TR, 2000-2500/20-30, 70-80, spin-echo images with and without fatsat were compared. The images were evaluated both qualitatively and quantitatively. Qualitative assessment was made with receiver-operating-characteristic (ROC) curve analysis of the confidence level of observers to detect the presence of disease, comparing fatsat with standard spin-echo sequences. ROC analysis showed greater interpreter confidence and accuracy for fatsat sequences than for standard spin-echo sequences. The measured signal-difference-to-noise (SD/N) ratio comparing upper abdominal organs with surrounding tissue revealed the highest values for short TR/TE regular spin echo, followed by short TR/TE fatsat. The highest SD/N ratio for hepatic masses was with long TR/TE fatsat followed by short TR/TE fatsat. The results of this study suggest that the fatsat technique may improve abdominal MR imaging.
Digital still camera system for megapixel CCD (1998)

We have developed a digital still camera system processing images by a combination of hardware and software to meet the demand of both high speed and flexibility. The system is capable of supporting CCDs with image size from VGA (640/spl times/480) to SXGA (1280/spl times/960), progressive and interlaced type scanning, and color filters of primary RGB and complementary MGCY signals. The still image processing time for YUV conversion is completed in approximately one frame for the progressive scan type CCD.
Flexible Link Functions in Nonparametric Binary Regression with Gaussian Process Priors (2015)

In many scientific fields, it is a common practice to collect a sequence of 0-1 binary responses from a subject across time, space, or a collection of covariates. Researchers are interested in finding out how the expected binary outcome is related to covariates, and aim at better prediction in the future 0-1 outcomes. Gaussian processes have been widely used to model nonlinear systems; in particular to model the latent structure in a binary regression model allowing nonlinear functional relationship between covariates and the expectation of binary outcomes. A critical issue in modeling binary response data is the appropriate choice of link functions. Commonly adopted link functions such as probit or logit links have fixed skewness and lack the flexibility to allow the data to determine the degree of the skewness. To address this limitation, we propose a flexible binary regression model which combines a generalized extreme value link function with a Gaussian process prior on the latent structure. Bayesian computation is employed in model estimation. Posterior consistency of the resulting posterior distribution is demonstrated. The flexibility and gains of the proposed model are illustrated through detailed simulation studies and two real data examples. Empirical results show that the proposed model outperforms a set of alternative models, which only have either a Gaussian process prior on the latent regression function or a Dirichlet prior on the link function.
Shadow volume reconstruction from depth maps (2000)

Current graphics hardware can be used to generate shadows using either the shadow volume or shadow map techniques. However, the shadow volume technique requires access to a representation of the scence as a polygonal model, and handling the near plane clip correctly and efficiently is difficult; conversely, accurate shadow maps require high-precision texture map data representations, but these are not widely supported. We present a hybird of the shadow map and shadow volume approaches which does not have these difficulties and leverages high-performance polygon rendering. The scene is rendered from the point of view of the light source and a sampled depth map is recovered. Edge detection and a template-based reconstruction technique are used to generate a global shadow volume boundary surface, after which the pixels in shadow can be marked using only a one-bit stencil buffer and a single-pass rendering of the shadow volume boundary polygons. The simple form of our template-based reconstruction scheme simplifies capping the shadow volume after the near plane clip.
Severe hypersensitivity reaction to minocycline. (2000)

Minocycline is a tetracycline derivative mainly used in the treatment of acne vulgaris in young persons. Adverse events have been reported with minocycline, although it can be considered a safe drug. We report a case of severe hypersensitivity reaction to minocycline in a young patient. Laboratory examinations, chest X-ray, skin test and skin biopsy were performed. Oral challenge test with minocycline was not carried out as it can be hazardous. A case of severe reaction to minocycline is described in this article. The clinical and laboratory findings may be helpful in diagnosing similar reactions for which the immunological mechanisms are unknown. Moreover, this type of reaction must be recognized early due to the potential fatal outcome.
Polyamine biosynthetic enzymes as drug targets in parasitic protozoa (2003)

Molecular, biochemical and genetic characterization of ornithine decarboxylase, S -adenosylmethionine decarboxylase and spermidine synthase establishes that these polyamine-biosynthetic enzymes are essential for growth and survival of the agents that cause African sleeping sickness, Chagas' disease, leishmaniasis and malaria. These enzymes exhibit features that differ significantly between the parasites and the human host. Therefore it is conceivable that exploitation of such differences can lead to the design of new inhibitors that will selectively kill the parasites while exerting minimal, or at least tolerable, effects on the parasite-infected patient.
Anthocyanins and Human Health: An In Vitro Investigative Approach (2004)

Anthocyanin pigments and associated flavonoids have demonstrated ability to protect against a myriad of human diseases, yet they have been notoriously difficult to study with regard to human health. Anthocyanins frequently interact with other phytochemicals to potentiate biological effects, thus contributions from individual components are difficult to decipher. The complex, multicomponent structure of compounds in a bioactive mixture and the degradation of flavonoids during harsh extraction procedures obscure the precise assignment of bioactivity to individual pigments. Extensive metabolic breakdown after ingestion complicates tracking of anthocyanins to assess absorption, bioavailability, and accumulation in various organs. Anthocyanin pigments and other flavonoids that are uniformly, predictably produced in rigorously controlled plant cell culture systems can be a great advantage for health and nutrition research because they are quickly, easily isolated, lack interferences found in whole fruits, can be elicited to provoke rapid and prolific accumulation, and are amenable to biolabeling so that metabolic fate can be investigated after ingestion.
EL TRABAJO EN EQUIPO EN UN ENTORNO VIRTUAL DE APRENDIZAJE (2012)

A pesar de que el trabajo en equipo es una competencia transversal interpersonal presente en la práctica totalidad de los Grados de Derecho, constituye una de las competencias con la que tanto docentes como estudiantes se encuentran menos familiarizados. A estos efectos, la utilización de las tecnologías de la información y la comunicación pueden facilitar el desarrollo de esta competencia. A la hora de planificar el trabajo en equipo, cuestión compleja, además del diseño de las actividades y la evaluación y la selección de las herramientas informáticas, el docente deberá determinar algunas cuestiones como el lugar y momento de su realización o los criterios para la formación de los grupos.
Estrogen receptor‐alpha (ER‐α) suppresses expression of its variant ER‐α36 (2009)

Recently, we identified and cloned a membrane-based estrogen receptor (ER), ER-alpha 36, which is transcribed from a previously unidentified promoter in the first intron of the original ER-alpha gene. We cloned the 5' flanking region of ER-alpha 36 and found the cloned DNA sequence possessed strong promoter activity. A single transcription initiation site was mapped and a number of putative regulatory elements for various transcription factors such as the Wilms' tumor suppressor, WT1 and estrogen receptor (ER) were identified in this region. Transient co-transfection experiments further demonstrated that ER-alpha suppresses ER-alpha 36 promoter activity in an estrogen-independent manner, which can be released by ER-alpha 36 itself.
Quality of talent development systems: results from an international study (2010)

In this study a purpose-built framework for specifying quality criteria – structure, process and outcome – in talent development systems was developed and evaluated in an explorative international study. A standardized survey was conducted with 1020 survey participants from four nations (Australia, China, Germany and the USA) and four sports disciplines (athletics, gymnastics, swimming and volleyball). The overall response rate was 56.4%. The principal component analysis confirmed three out of the four determinants of the quality dimension structure (goals, resources, and opportunities). They were based on five to eleven items with a minimum factor loading of .51. For each of the dimensions process and outcome one factor with a minimum factor loading between .59 and .65 could be statistically confirmed. These findings suggest that the chosen conceptual framework is applicable for specifying quality criteria of talent development systems in different nations and sports. It can be used in further studies comparing the quality of sports systems between different nations and might be useful to develop a quality management approach for elite sport.

Simplifying the Integration of Processing Elements in Computing Systems Using a Programmable Controller (2005)

As technology sizes decrease and die area increases, designers are creating increasingly complex computing systems using FPGAs. To reduce design time for new products, the reuse of previously designed intellectual property (IP) cores is essential. However, since no universally accepted interface standards exist for IP cores, there is often a certain amount of redesign necessary before they are incorporated into the new system. Furthermore, the core's functionality may need updating to support the requirements of the new application. This paper demonstrates how the SIMPPL system model allows designers to rapidly implement on-chip systems comprising multiple computing elements (CEs). Furthermore, using a controller-based interface to manage inter-CE transfers enables users to easily adapt the control sequence of individual CEs to suit the needs of new applications without necessitating the redesign of other elements in the system. Two systems using three different hardware modules adapted to CEs are described to illustrate the power and simplicity of the SIMPPL model. It required a total of six hours to implement both designs on-chip once the individual CEs had been designed.
