Acute Cerebellar Edema Following Intra-arterial Tissue Plasminogen Activator Thrombolysis for Basilar Artery Occlusion —Case Report— (1996)

A 61-year-old male developed acute cerebellar swelling after thrombolytic therapy for basilar artery occlusion. He was treated with intra-arterial tissue plasminogen activator 12 hours following symptomatic onset, and did well in the immediate post-treatment period but deteriorated the next day. Computed tomography demonstrated acute cerebellar edema and hydrocephalus. Suboccipital external decompression and ventricular drainage were performed. He survived and 1 year later he could perform daily activities at home. Computed tomography and angiography are essential to monitor the post-treatment course following thrombolysis of vertebrobasilar occlusive disease.
Mitigation Strategies for Microbiologically Influenced Corrosion in Gas Industry Facilities (1989)

Abstract A study of microbiologically influenced corrosion (MIC) and its mitigation in gas industry facilities, sponsored by the Gas Research Institute, was conducted during 1986-88. The results show that MIC commonly occurs on both external and internal surfaces of pipes, in down hole tubulars and in process equipment such as separators. Mitigation strategies were tested in side-stream devices at several sites. The results demonstrate that many biocides and corrosion inhibitors are relatively ineffective in controlling the surface microbial populations, at least under the conditions of the tests. Detailed studies with glutaraldehyde demonstrated that reestablishment of surface MIC communites after removal of this biocide was very rapid. Continuous treatment with glutaraldehyde led to the development of surface microbial communities "resistant" to the effects of the biocide. Intermittent treatment with glutaraldehyde, when applied frequently enough, effectively controlled the surface MIC populations. Heat treatment was very effective and might be used in some facilities (e.g., separators) to prevent inputs of large amounts of MIC bacteria into pipelines. The results of field investigations of external MIC of buried gas pipelines are summarized and possible mitigation measures discussed.
Boiling-Water Reactor internals aging degradation study. Phase 1 (1993)

This report documents the results of an aging assessment study for boiling water reactor (BWR) internals. Major stressors for BWR internals are related to unsteady hydrodynamic forces generated by the primary coolant flow in the reactor vessel. Welding and cold-working, dissolved oxygen and impurities in the coolant, applied loads and exposures to fast neutron fluxes are other important stressors. Based on results of a component failure information survey, stress corrosion cracking (SCC) and fatigue are identified as the two major aging-related degradation mechanisms for BWR internals. Significant reported failures include SCC in jet-pump holddown beams, in-core neutron flux monitor dry tubes and core spray spargers. Fatigue failures were detected in feedwater spargers. The implementation of a plant Hydrogen Water Chemistry (HWC) program is considered as a promising method for controlling SCC problems in BWR. More operating data are needed to evaluate its effectiveness for internal components. Long-term fast neutron irradiation effects and high-cycle fatigue in a corrosive environment are uncertainty factors in the aging assessment process. BWR internals are examined by visual inspections and the method is access limited. The presence of a large water gap and an absence of ex-core neutron flux monitors may handicap the use of advanced inspection methods, such as neutron noise vibration measurements, for BWR.
Automatic excitement-level detection for sports highlights generation (2010)

The problem of automatic excitement detection in baseball videos is considered and applied for highlight generation. This paper focuses on detecting exciting events in video using complementary information from the audio and video domains. First, a new measure for non-stationarity which is extremely effective in separating background from speech is proposed. This new feature is employed in an unsupervised GMM-based segmentation algorithm that identifies the sports commentators speech within the crowd background. Thereafter, the “level-of-excitement” is measured using features such as pitch, F1‐F3 center frequencies, and spectral center of gravity extracted from the commentators speech. Our experiments using actual baseball videos show that these features are well correlated with human assessment of excitability. Furthermore, slow-motion replay and baseball pitching-scenes from the video are also detected to estimate scene end-points. Finally, audio/video information is fused to rank-order scenes by “excitability” in order to generate highlights of user-defined timelengths. The techniques described in this paper are generic and applicable to a variety of topic and video/acoustic domains. Index Terms: Video Segmentation, Multimodal Signal Processing
Proyectos satisfactorios de aprendizaje combinado en 2006: Experiencias en diferentes entornos de aprendizaje formal, no formal e informal (2007)

Socios europeos de once países que trabajan en el marco de la Blended Learning Institutions¿ Cooperative (blinc) han aplicado metodologías de aprendizaje mixto basadas en Internet en diferentes grupos y contextos de aprendizaje, en tres proyectos distintos. El proyecto INTEGRATION se ocupa de la formación de personal intercultural para organizaciones que trabajan con clientes y beneficiarios multiétnicos. Nueve socios de seis naciones han desarrollado material audiovisual de formación y aprendizaje. Se utilizó un enfoque videográfico de la formación intercultural, analizando situaciones concretas de encuentros interculturales desde una perspectiva de incidente crítico, y produciendo y documentando ¿microcomunicaciones interculturales¿ en forma de cortometrajes en línea. En el marco del proyecto Joint Environmental Management (JEM!), financiado por Socrates, socios del Programa de Acción Conjunta de cinco países aplicaron un eCoaching System para la introducción de la gestión medioambiental en las escuelas europeas. El sistema incluye cursos completos, material de formación y directrices de acompañamiento para los profesores, formadores o asesores. El sistema aplicado que se usa en el proyecto JEM! se desarrolló en el marco de otro proyecto denominado ¿IEM in hospitals¿, que fue reconocido como uno de los cinco mejores proyectos, entre un total de 2.500, desde el año 1992. El proyecto JEM! transfirió ese enfoque a las escuelas europeas. La formación y el asesoramiento se llevan a cabo desde perspectivas de aprendizaje combinado y se puede acceder a todo el sistema desde el sitio web interactivo del proyecto. Ambos proyectos son ejemplos de cómo conceptos innovadores de aprendizaje facilitado por las TI pueden materializarse en diversos entornos de aprendizaje formal e informal con grupos, contenidos y objetivos de aprendizaje distintos. Demostraron claramente que el éxito depende, en buena medida, de la calidad del diseño educativo aplicado en los contextos de aprendizaje combinado. Por esa razón, el proyecto Advanced Blended Learning and Didactics (A-B-C-D) (Grundtvig 1.1, 2005-2007) tiene como objetivo el desarrollo de un curso completo de formación para diseñadores de aprendizaje combinado. Estos cursos tendrán lugar en mayo y septiembre de 2007, en Atenas y en Burdeos, con una fase preliminar sobre e-learning. Asimismo, el curso ofrecerá oportunidades para desarrollar proyectos de aprendizaje combinado individuales mediante herramientas Web 2.0, como blogs, wikis, e-portfolios e instrumentos de comunicación síncrona por Internet, como conferencias en línea o Skype.
Expression of the chemically synthesized gene for ribonuclease T1 in <i>Escherichia coli</i> using a secretion cloning vector (1988)

The gene for ribonuclease T1 from Aspergillus oryzae has been chemically synthesized using the segmental support technique. An Escherichia coli clone producing the ribonuclease at high levels was constructed by linking the gene downstream to the region coding for the signal peptide of the OmpA protein (a major outer membrane protein of E. coli), using the secretion cloning vector pIN-III-ompA2. This strategy was employed in order to circumvent a possible toxic effect of the gene product on the host cell. Active ribonuclease containing four additional amino acids at the N-terminus could be isolated from the periplasmic fraction of the host. The final yield after purification was 20 mg enzyme/l liquid culture. With respect to immunological, catalytic and specific behaviour, no qualitative differences could be detected between the enzyme from the over-producing E. coli strain and ribonuclease T1 isolated from A. oryzae.
Identification and Population Dynamics of Yeasts inSourdough Fermentation Processes by PCR-Denaturing GradientGelElectrophoresis (2003)

Four sourdoughs (A to D) were produced under practical conditions, using a starter obtained from a mixture of three commercially available sourdough starters and baker's yeast. The doughs were continuously propagated until the composition of the microbiota remained stable. A fungi-specific PCR-denaturing gradient gel electrophoresis (DGGE) system was established to monitor the development of the yeast biota. The analysis of the starter mixture revealed the presence of Candida humilis, Debaryomyces hansenii, Saccharomyces cerevisiae, and Saccharomyces uvarum. In sourdough A (traditional process with rye flour), C. humilis dominated under the prevailing fermentation conditions. In rye flour sourdoughs B and C, fermented at 30 and 40 degrees C, respectively, S. cerevisiae became predominant in sourdough B, whereas in sourdough C the yeast counts decreased within a few propagation steps below the detection limit. In sourdough D, which corresponded to sourdough C in temperature but was produced with rye bran, Candida krusei became dominant. Isolates identified as C. humilis and S. cerevisiae were shown by randomly amplified polymorphic DNA-PCR analysis to originate from the commercial starters and the baker's yeast, respectively. The yeast species isolated from the sourdoughs were also detected by PCR-DGGE. However, in the gel, additional bands were visible. Because sequencing of these PCR fragments from the gel failed, cloning experiments with 28S rRNA amplicons obtained from rye flour were performed, which revealed Cladosporium sp., Saccharomyces servazii, S. uvarum, an unculturable ascomycete, Dekkera bruxellensis, Epicoccum nigrum, and S. cerevisiae. The last four species were also detected in sourdoughs A, B, and C.
Cloning and characterization of bonnet monkey GnRH receptor (2000)

Gonadotrophin releasing hormone (GnRH) plays an important role in the reproductive processes of both males and females. It is synthesized by the hypothalamus and binds to a specific receptor on the pituitary to bring about the release of the gonadotrophins, lutineizing hormone and follicle stimulating hormone, which in turn bring about the release of the gonadal steroids. Although the structure of the GnRH receptor (GnRHR) has been elucidated from a number of sources, no information is available about the receptor from the non-human primate species. Here we report the cloning and characterization of the receptor from the pituitary of the bonnet monkey. Antiserum to a bacterially expressed recombinant fragment was used in Western blot analysis and fluorescence microscopy to demonstrate the presence of GnRHR in both human and monkey placentae and pituitary.
Measurement of X-Ray Dielectric Constants With Coherent Transition Radiation (1986)

We have developed a technique for measuring the energy-resolved angular distribution of longitudinally coherent transition radiation generated in multiple-foil targets. This paper will demonstrate how data generated by these measurements can be used to determine the dielectric constants of materials in the soft x-ray spectral region.
Magnetic tunneling applied to memory (invited) (1997)

Random access magnetoresistive memories have been designed using anisotropic magnetoresistive (AMR) material and more recently giant magnetoresistive (GMR) material. The thin films in these memories have low sheet resistivities (about 10 Ω/sq), resulting in cell resistances of 10 to 100 Ω at competitive areal densities. High sense currents of a mA or more are required to get signals on the order of a few mV. Spin dependent tunneling (SDT) devices are intrinsically high impedance, with typical equivalent resistance values of 104–109 Ω for a square micron area. SDT cells have the potential for signals on the order of 10 mV with lower sense currents, and hence, faster access times than GMR memory. A GMR pseudospin valve memory concept is presented for comparison with SDT memory. Three different design approaches are discussed for SDT memory: (1) high-density memory arrays similar to those in AMR and GMR memories, (2) a transistor per cell approach similar to semiconductor dynamic random access memory, and (3) embedded SDT devices in a flip–flop cell similar to semiconductor static random access memory. The conclusions are: (1) SDT memory is potentially higher speed than GMR memory, (2) SDT memory has no area advantage compared with dense GMR memory, and (3) risks with SDT memory include (a) processing ultrathin dielectric layers uniformly and reliably that are compatible with integrated circuits and (b) attaining sufficiently low impedance levels to get a satisfactory signal-to-noise ratio in a small area cell.
[New findings on the diagnosis and therapy of prion diseases]. (2002)

Spongiform encephalopathies are the fatal diseases, that affect the brain tissue of mammals. They are caused by a conformational changed prion protein. There is no adequate diagnostic test for in vivo identification of prion protein. Disease can be diagnosed only by clinical sings and EEG in new variant of Creutzfeldt-Jakob disease. Post mortem, histopathological examination of brain tissue reveals spongiform changes and immunohistochemistry detects disease-related prion protein. Appropriate diagnostic in vivo tests are not developed yet; therefore extensive researches are ongoing aimed to introduce such methods. This review describes a few promising experimental methods, which may develop into diagnostic tests in the future: detection of prions in urine samples, PMCA (protein misfolding cyclic amplification), DATAS (differential analysis of transcripts with alternative splicing), SELEX (in vitro selection), detection of prions in tonsils and detection of copper and manganese dysbalance in tissues. Current therapy strategy is based on testing of some known drugs (quinacrine, chlorpromazine), and antioxidant and antibody treatments. The detection of NSE (neuron-specific enolase) and cholesterol in meat products reveals the presence of brain and spinal cord tissue. The spreading of spongiform encephalopathies can be diminished by utilising the adequate in vivo diagnostic tests, effective therapy strategy and preventive steps.
MicroRNA and mRNA Features of Malignant Pleural Mesothelioma and Benign Asbestos-Related Pleural Effusion (2015)

Specific microRNAs and mRNAs may have diagnostic utility in differentiating patients with malignant pleural mesothelioma from benign asbestos-related pleural effusion. These studies may be particularly helpful in patients who reside in a region with a high incidence of mesothelioma.
Syntheses and Properties of Surfactants Containing Organometals. VII. (1970)

The authors synthesized cationic surfactants containing dimethylpolysiloxane whose hydrophobic groups were linear, two-chained and three-chained, and investigated their surface activities.Regardless of the structure of hydrophobic groups, these cationic surfactants indicated excellent surface activities to give the lowest values of surface tension in aqueous solutions, as low as 22 to 23 dynes/cm. But they lost their surface activities in acidic (pH<4.5) and basic (pH>9.5) aqueous solutions.They also indicated excellent foaming ability and foam stability, and are expected to have a utility as foaming agents.In respect to the bacteriostatic action, the cationic surfactants(CH3CH2CH2CH2) 3M (CH2) 3N+ (CH3) 3Cl- (M=Si, Sn) indicated especially strong activities.
Tyrosine kinase 2 and interferon regulatory factor 5 polymorphisms are associated with discoid and subacute cutaneous lupus erythematosus (2009)

Lupus erythematosus (LE) is a heterogeneous disease ranging from skin-restricted manifestations to a progressive multisystem disease. The specific skin lesions include chronic cutaneous, subacute cutaneous and acute cutaneous LE. Both genetic and environmental factors are involved in the development of LE. However, reports on the genetic background of cutaneous lupus erythematosus (CLE) forms, namely discoid (DLE) and subacute cutaneous lupus erythematosus (SCLE), are sparse. We investigated whether the known systemic LE (SLE) susceptibility genes also predispose to CLE. Altogether, 219 Finnish patients with DLE or SCLE and 356 healthy controls were recruited. Single nucleotide polymorphisms tagging reported risk genes were genotyped. Tyrosine kinase 2 (TYK2) rs2304256 was associated with increased risk of DLE (P = 0.012, OR = 1.47, 95% CI = 1.01-1.98). Expression of TYK2 was demonstrated by immunohistochemistry in macrophage-like cells and neutrophils and interferon regulatory factor 5 (IRF5) in macrophage- and fibroblast-like cells of DLE, SCLE and SLE skin. IRF5 rs10954213 showed association with DLE (P = 0.017, OR = 1.40, 95% CI = 1.06-1.86) and SCLE (P = 0.022, OR = 1.87, 95% CI = 1.09-3.21). A haplotype of cytotoxic T-lymphocyte-associated protein 4 (CTLA4) showed association with DLE (P = 0.0065, OR = 2.51, 95% CI = 1.25-5.04). Our results show that the TYK2, IRF5 and CTLA4 genes previously associated with SLE also confer risk for DLE and SCLE, suggesting that different LE subphenotypes may share pathogenetic pathways.
Fuzzy segmentation and recognition of continuous human activities (2014)

Most previous research has focused on classifying single human activities contained in segmented videos. However, in real-world scenarios, human activities are inherently continuous and gradual transitions always exist between temporally adjacent activities. In this paper, we propose a Fuzzy Segmentation and Recognition (FuzzySR) algorithm to explicitly model this gradual transition. Our goal is to simultaneously segment a given video into events and recognize the activity contained in each event. Specifically, our algorithm uniformly partitions the video into a sequence of non-overlapping blocks, each of which lasts a short period of time. Then, a multi-variable time series is creatively formed through concatenating the block-level human activity summaries that are computed using topic models over each block's local spatio-temporal features. By representing an event as a fuzzy set that has fuzzy boundaries to model gradual transitions, our algorithm is able to segment the video into a sequence of fuzzy events. By incorporating all block summaries contained in an event, the proposed algorithm determines the most appropriate activity category for each event. We evaluate our algorithm's performance using two real-world benchmark datasets that are widely used in the machine vision community. We also demonstrate our algorithm's effectiveness in important robotics applications, such as intelligent service robotics. For all used datasets, our algorithm achieves promising continuous human activity segmentation and recognition results.
Spectroscopic Analysis of Temperature Variation of EDM Arc Plasma. (1997)

This paper describes the measurement of temperature variation of the arc plasma generated by the EDM pulse discharges in air using the spectroscopic analysis. Intensities of two radiation lines from copper atoms in the arc plasma are measured simultaneously using two monochrometers, and the temperature is obtained based on the line pair method. Although the measured radiant flux is significantly affected by the configurations of the electrodes, the obtained apparent temperatures during the discharge duration is between 6, 000 to 7, 000K regardless of the electrode configurations, discharge current or discharge duration. In the discharge interval, however, it takes longer time to decrease the plasma temperature and deionize the plasma, when the discharge current is higher, the discharge duration is longer or the rate of heat transfer from the plasma to the electrodes is lower. In a series of pulse discharges, the plasma temperature increases with the lapse of time as the surface temperatures of the electrodes are elevated.
The electro-chemical basis of manhole events (2009)

The article discusses the starting point for manhole events, defined as phenomena ranging from smoking manholes, fires, and cover blow-offs, as one that is mainly due to insulation failure of secondary cables, and for the most part, is the result of an aging infrastructure.
Optimal space–time precoding of artificial sensory feedback through mutichannel microstimulation in bi-directional brain–machine interfaces (2012)

Brain-machine interfaces (BMIs) aim to restore lost sensorimotor and cognitive function in subjects with severe neurological deficits. In particular, lost somatosensory function may be restored by artificially evoking patterns of neural activity through microstimulation to induce perception of tactile and proprioceptive feedback to the brain about the state of the limb. Despite an early proof of concept that subjects could learn to discriminate a limited vocabulary of intracortical microstimulation (ICMS) patterns that instruct the subject about the state of the limb, the dynamics of a moving limb are unlikely to be perceived by an arbitrarily-selected, discrete set of static microstimulation patterns, raising questions about the generalization and the scalability of this approach. In this work, we propose a microstimulation protocol intended to activate optimally the ascending somatosensory pathway. The optimization is achieved through a space-time precoder that maximizes the mutual information between the sensory feedback indicating the limb state and the cortical neural response evoked by thalamic microstimulation. Using a simplified multi-input multi-output model of the thalamocortical pathway, we show that this optimal precoder can deliver information more efficiently in the presence of noise compared to suboptimal precoders that do not account for the afferent pathway structure and/or cortical states. These results are expected to enhance the way microstimulation is used to induce somatosensory perception during sensorimotor control of artificial devices or paralyzed limbs.
Superconducting kinetic inductance bolometer (1989)

The authors are developing a bolometer with a temperature sensor based on the temperature dependence of the inductance of a superconducting microstrip line. As a first step in exploring this idea experimentally, they have designed experiments to test only the temperature sensor. The experimental devices are all-niobium inductance thermometers fabricated on silicon substrates which have been deeply etched to provide areas of relative thermal isolation. The ground plane superconductor is thin enough so that its kinetic inductance dominates the audio frequency impedance of the stripline near its critical temperature, at 0.9 T/sub c/. This differential thermometer uses a commercial SQUID (superconducting quantum interference device) as the preamplifier. Preliminary results demonstrate a proof-of-principle for the thermometer design. An important quality factor for this type of measurement system is the depth of the null. The authors achieved a high value of 0.4*10/sup -6/, which is satisfying for a first try.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
