Acoustic-phonetic features for the automatic classification of stop consonants (2001)

In this paper, the acoustic-phonetic characteristics of the American English stop consonants are investigated. Features studied in the literature are evaluated for their information content and new features are proposed. A statistically guided, knowledge-based, acoustic-phonetic system for the automatic classification of stops, in speaker independent continuous speech, is proposed. The system uses a new auditory-based front-end processing and incorporates new algorithms for the extraction and manipulation of the acoustic-phonetic features that proved to be rich in their information content. Recognition experiments are performed using hard decision algorithms on stops extracted from the TIMIT database continuous speech of 60 speakers (not used in the design process) from seven different dialects of American English. An accuracy of 96% is obtained for voicing detection, 90% for place of articulation detection and 86% for the overall classification of stops.

Two new species of <i>Pseudoniphargus</i> (Amphipoda), in Bermudian groundwaters* (1986)

The genus Pseudoniphargus comprises a number of stygobiont Amphipoda, distributed on both sides of the Atlantic. In Bermuda, groundwaters are inhabited by two species. P. grandimanus and P. carpalis , both new. They occur throughout the entire salinity spectrum, from infrahalne to euhaline, but are most abundant in oligohaline waters. Large adults, but no ovigerous specimens. arc found at greater distance from the sea coast than juveniles, which may indicate that Pseudoniphargus needs anchihaline/marine waters for its reproduction and that juveniles migrate inland to grow up.
Novel Corrosion Inhibitors Derived from Agricultural by-Products: Potential Applications in Water Treatment (2012)

Abstract The corrosion inhibitive properties of biodegradable, and non-hazardous corn-based by-products were evaluated and screened to identify potential applications. The properties evaluated included contact- and vapor-phase corrosion inhibition, as well as the ability to act as a barrier against corrosive environments such as high acid concentration and salt solutions. Rust and scale removing properties were also tested. During these investigations, it was discovered that a solvent extract from dried distilled grains with solubles (DDGS) demonstrated very good corrosion protection properties for steel in acidic environments. A variety of plant extracts have been shown to inhibit corrosion of steel in acidic conditions, but such activity has not previously been demonstrated with corn extracts. Aqueous corn extracts also proved to provide corrosion protection when used as an inhibitor in de-icing compounds. The details of these findings and potential applications are reported herein.
Facile Carbon Monoxide Reduction at Intramolecular Frustrated Phosphane/Borane Lewis Pair Templates (2013)

Ein neuer Reaktionspfad: Kohlenmonoxid wird leicht mit Piers' Boran und einem frustrierten Lewis-Paar (FLP) zu einem FLP-stabilisierten Formylboran reduziert (siehe Bild). Diese Reaktion kann als ein typisches Beispiel für die effiziente Aktivierung eines kleinen Moleküls durch ein FLP betrachtet werden.
SOME ULTRA-MICROTOMY STUDIES OF NICKEL FLUORIDE FILMS ON NICKEL FOIL (1964)

Herein, we report the successful endovascular treatment of an expanding EH following a contralateral craniotomy. Active bleeding of the MMA was observed via angiography and may predict further EH expansion. Endovascular exploration and possible treatment can be justified in patients with EH that do not have a clear surgical indication.
Over 60km Transmission Extended Reach 10G-EPON System with a Wide 29dB Dynamic Range Burst-mode Receiver (2012)

We investigated the extended 10G-EPON system which has wide coverage area over 20km transmission. Due to wide 29dB dynamic range and low dispersion penalty of 10.3G optical transceiver, we realized the extended 10G-EPON system which has the wide transmission area over 60km from OLT.
The dynamics of the reaction D+2+F(2<i>P</i>)→FD++D at kinetic energies between 0.002 and 30 eV (1983)

The merged molecular beam technique has been used to study the reaction D+2+F(2P)→FD++D over the kinetic energy range from 0.002 to 30 eV. The energy dependence of the absolute total reaction cross section at low kinetic energies indicates that reaction occurs with unit probability for capture collisions on potential energy surfaces which correlate with Π intermediates. This result is consistent with the adiabatic state correlations, which connect the reactants to the ground state products FD+(2Π)+D(2S) via both the 1Π and 3Π surfaces in collinear approches. At higher energies, an inflection in the reaction cross section is thought to be caused by onset of the endoergic reaction to give excited state products FD+(2Σ)+D(2S). The reaction mechanism is direct over the entire range of collision energies, with the FD+ product scattered preferentially in the direction of the incident F-atom reactant in the center-of-mass system, except for extremely high collision energies (Ei=25 eV), where a roughly symmetric distribution is seen. Very little theoretical work has been carried out on the dynamics of reactions between two open-shell species. The relative simplicity of the D+2+F(2P) system makes it an attractive candidate for such studies.
Atrial Fibrillation and Intra-arterial Thrombolysis (2001)

P169 Background: Atrial fibrillation (AF) is associated with increased stroke severity and mortality. Intra-arterial thrombolysis may be of particular benefit for these patients. Methods: Review of 90 consecutive intra-arterial thrombolysis cases (mean age 69 years, range 25–94; 53% female) performed at UCLA from July 1992 to June 2000. Clinical, radiologic, and angiographic variables were analyzed in relation to AF. Results: AF (56% paroxysmal, 44% chronic) was identified in 53% of all cases. Only 54% of AF was present on admission, with delayed onset in 17% (median 3 days), and no observed in-hospital AF in 29% despite a history of AF. AF was new-onset in 23% of cases. At time of admission, only 30% of known AF patients were receiving antithrombotic treatment for stroke prevention per ACCP guidelines. Anticoagulation was subtherapeutic at presentation in all 11 chronically anticoagulated patients. Time to presentation was shorter for AF patients, 50 minutes vs 67 minutes, p<.03. The recanalization rate (TIMI ≥ 2) in AF patients was 67% (vs 69% in non-AF patients, p=.81). Hemorrhage rates trended higher in AF (46% vs 31%, p=.15), including parenchymal hematomas (38% vs 21%, p=.10) and symptomatic hemorrhages (25% vs 10%, p=.06). Deficit severity at presentation in patients with AF was median NIHSS 16 (vs 15 in non-AF patients, p=.29). Deficit severity improved at day 7 in AF patients to median NIHSS 12 (vs 6 in non-AF patients, p=.32). Functional outcomes at day 7 were similar between groups, with percent dead or disabled (mRS > 2) 60% in AF patients and 52% in non-AF patients, p=.44. AF was associated with a trend toward elevated in-hospital mortality (19% vs 7%, p=.11). Among AF patients, AF was classified as etiologic of stroke in 79% and not etiologic in 21% (SPAF III classification algorithm). No cases of recurrent symptomatic ischemia occurred during hospitalization. Conclusions: In this series, intra-arterial therapy among patients with AF achieved recanalization in 67%, with symptomatic hemorrhagic transformation in 25%, and good functional outcome in 40%. Intra-arterial thrombolysis is a promising treatment for patients with ischemic stroke and atrial fibrillation.
Analgesic Activity of Some 3‐(Arylpiperidinomethyl)‐2‐benzoxazolinone Derivatives (1989)

In our previous study, the antimicrobial activities of 16 new compounds synthetized by reacting 2-benzoxazolinones with derivatives of piperidine were determined. In this study, the analgesic activities of these compounds, using modified Koster's test is investigated. The analgesic activities of these compounds are higher than that of O-acetyl salicilic acid.
A monoclonal antibody inhibiting leucocyte adhesion blocks induction of IL-2 production but not IL-2 receptor expression. (1987)

Monoclonal antibody 60.3 defines the leucocyte antigen CD 18 and recognizes a cell surface glycoprotein with an apparent molecular weight (MW) of 90,000 expressed by most human peripheral blood and bone marrow cells. This antibody can, among other things, block phorbol ester-induced adhesion among human mononuclear leucocytes. We show in this study that phorbol esters alone can induce peripheral blood mononuclear cells (PBL) to secrete interleukin-2 (IL-2) and that the IL-2-dependent cell line CTLL can be used for measuring this lymphokine without influence of the phorbol esters themselves. These findings make it possible to analyse the capacity of antibody 60.3 to interfere with IL-2 production and receptor expression by phorbol ester or phytohaemagglutinin (PHA)-treated human PBL. A significant positive correlation between blockage of induced cell aggregation by antibody 60.3 and reduction in IL-2 release was observed. The addition of interleukin-1 (IL-1) restored IL-2 secretion in PHA-treated, but not in 4-beta-phorbol 12, 13-dibutyrate [P(Bu)2]-treated, cells in the presence of this antibody. In parallel, IL-2 receptor expression was determined by immunofluorescence using biotinylated anti-IL-2 receptor (Tac) antibodies. FACS analysis showed that IL-2 receptor expression was unaffected by antibody 60.3, whereas DNA synthesis of the same P(Bu)2-treated PBL was inhibited. However, addition of external recombinant IL-2 overcame this proliferation blockade. These results indicate that a cell-to-cell adhesion step is necessary for the production of IL-2, but not for the expression of its receptor on both PHA- and P(Bu)2-treated human PBL.
In-flight system identification for the CRAF/Cassini spacecraft (2003)

The feasibility and payoffs of conducting in-flight system dynamics identification for the CRAFT/Cassini/(C/C) spacecraft are studied. The primary control modes of: (a) the boom-mounted high precision scan platform articulation/pointing control; and (b) the main engine thrust vector control are analyzed. Identification of key transfer functions and models and subsequent design of modern robust controllers by recently developed advanced processing algorithms are demonstrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
BIGT control optimisation for overall loss reduction (2013)

In this paper we present the latest results of utilizing MOS-control (MOSctrl) to optimize the performance of the Bi-mode Insulated Gate Transistor (BIGT) chip. The adaption of the BIGT technology enables higher output power per footprint. However, to enable the full performance benefit of the BIGT, the optimisation of the known standard MOS gate control is necessary. This optimisation is being demonstrated over the whole current and temperature range for the BIGT diode turn-off and BIGT turn-on operation. It is shown that the optimum control can offer a performance increase up to 20% for high voltage devices.
Mathematical Modelling of the Primary and Secondary Drying Stages of Bulk Solution Freeze-Drying in Trays: Parameter Estimation and Model Discrimination by Comparison of Theoretical Results With Experimental Data (1997)

ABSTRACT A mathematical model was constructed and solved in order to describe quantitatively the dynamic behavior of the primary and secondary drying stages of the freeze-drying of pharmaceuticals in trays. The theoretical results were compared with the experimental data of the freeze-drying of skim milk, and the agreement between the experimental data and the theoretical results is good. Detailed model calculations have indicated that the contribution of the removal of hound (unfrozen) water to the total mass flux of the water removed during primary drying, is not significant. For this reason, it was found that one could not
SOME STATISTICS FROM ALGOL PROGRAMS (1970)

A substantial amount of statistical information is given of Algol programs run at the National Physical Laboratory. This involved the monitoring of 155 million instructions. Information from this can be used by compiler-writers in deciding which features of a compiler are worth optimising. Statistics are also given of the occurrence of basic symbols in source text and of instructions in compiled programs. From the execution statistics, an Algol mix has been devised. This has been run on 18 Algol systems giving a clear indication of the weaknesses and merits of each one, as well as a comparison of their execution speeds.

Efficacy and safety of etanercept in moderate-to-severe asthma: a randomised, controlled trial (2010)

Increased tumour necrosis factor-α levels have been observed in bronchial biopsies and induced sputum from subjects with severe asthma. We investigated etanercept (ETN) as a therapeutic option for treating moderate-to-severe persistent asthma. In this 12-week, randomised, double-blind, placebo-controlled, phase 2 trial, subjects (n=132) with moderate-to-severe persistent asthma received subcutaneous injections of 25 mg ETN or placebo twice weekly, and were evaluated at baseline, and at weeks 2, 4, 8 and 12. The primary end-point was the change from baseline to week 12 in pre-bronchodilator forced expiratory volume in 1 s (FEV1)% predicted. Secondary end-points included morning peak expiratory flow, FEV1% pred, Asthma Control Questionnaire (5-item version), asthma exacerbations, provocative concentration of methacholine causing a 20% decrease in FEV1, and the Asthma Quality of Life Questionnaire. No significant differences were observed between ETN and placebo for any of the efficacy end-points. ETN treatment was well tolerated, with no unexpected safety findings observed during the study. Clinical efficacy of ETN was not shown in subjects with moderate-to-severe persistent asthma over 12 weeks. However, ETN treatment was a well-tolerated therapy. Studies in specific subsets of patients with asthma with longer-term follow-up may be needed to fully evaluate the clinical efficacy of ETN in this population.
Two New Nitrogenous Sesquiterpenes from the Sponge <i>Axinyssa aplysinoides</i> (1997)

Bioassay-guided fractionation of the EtOAc extract of the Palauan sponge Axinyssa aplysinoides yielded two novel alkaloids, 1 and 2. The structure of 2-(formylamino)trachyopsane (1) was determined by X-ray analysis; and the structure of N-phenethyl-N'-2-trachyopsanylurea (2), by interpretation of the spectral data.
Human Myeloma Cell Lines Induce Osteoblast Downregulation of CD99 Which Is Involved in Osteoblast Formation and Activity (2015)

CD99 is a transmembrane glycoprotein expressed in physiological conditions by cells of different tissues, including osteoblasts (OBs). High or low CD99 levels have been detected in various pathological conditions, and the supernatant of some carcinoma cell lines can modulate CD99 expression in OB-like cells. In the present work we demonstrate for the first time that two different human myeloma cell lines (H929 and U266) and, in a less degree, their conditioned media significantly downregulate CD99 expression in normal human OBs during the differentiation process. In the same experimental conditions the OBs display a less differentiated phenotype as demonstrated by the decreased expression of RUNX2 and Collagen I. On the contrary, when CD99 was activated by using a specific agonist antibody, the OBs become more active as demonstrated by the upregulation of Alkaline Phosphatase, Collagen I, RUNX2, and JUND expression. Furthermore, we demonstrate that the activation of CD99 is able to induce the phosphorylation of ERK 1/2 and AKT intracellular signal transduction molecules in the OBs.
Postoperative Deterioration in Health Related Quality of Life as Predictor for Survival in Patients with Glioblastoma: A Prospective Study (2011)

Early deterioration in HRQOL after surgery is independently and markedly associated with impaired survival in patients with glioblastoma. Deterioration in patient reported HRQOL after surgery is a meaningful outcome in surgical neuro-oncology, as the measure reflects both the burden of symptoms and treatment hazards and is linked to overall survival.
A reconfigurable stochastic model simulator for analysis of parallel systems (2002)

Markov chain and queueing model are convenient tools with which to analyze parallel systems for architects. For a high speed simulation and easy modeling, a reconfigurable Markov chain/queueing model simulation system called RSMS (Reconfigurable Stochastic Model Simulator) is proposed. A user describes the target system in a dedicated description language called Taico. The description is automatically translated into the HDL description of the Markov chain/queueing model simulator. Then, the simulator is implemented on the FPGA devices of the reconfigurable system, and directly executed. Evaluation results with example parallel systems demonstrate that the performance of the proposed system is much superior to that of a common workstation.

Magnetic resonance studies of concanavalin A: location of the binding site of alpha-methyl-D-mannopyranoside. (1976)

The longitudinal nuclear magnetic relaxation times of the methyl protons of alpha-methyl-D-mannopyranoside have been measured at 90 MHz and 270 MHz in solutions of concanavalin A complexed with: (i) Mn2+ and Ca2+; and (ii) Zn2+ and Ca2+. Zn2+ and Mn2+ are known to bind in site S1 and Ca2+ in site S2 of concanavalin A. Both sites must be occupied before monosaccharides will bind to the protein. In order to extract T1p, the paramagnetic contribution to the bound methyl relaxation time, from these observations the relaxation time of uncomplexed sugar was determined. Free Mn2+ contributed insignificantly to the latter value; however, outer sphere relaxation was found to be large at bound Mn2+ concentrations greater than 1 mM. Comparison of the results obtained at the two frequencies allowed the determination of the correlation time for the interaction between the methyl protons and the bound Mn2+ and the distance between them (21.5 +/- 1.2 A). In contrast to previous results from nuclear magnetic resonance studies, this distance is consistent with binding at the cavity proposed for the saccharide binding site by Becker et al. [J. Biol. Chem. 250, 1513 (1975)], although it does not preclude possible binding sites on the surface of the molecule.
Effects of oral hygiene products containing lactoperoxidase, lysozyme, and lactoferrin on the composition of whole saliva and on subjective oral symptoms in patients with xerostomia (1996)

This study evaluates the effects of two oral hygiene products containing nonimmunoglobulin antimicrobial agents on whole saliva and on subjective oral symptoms in patients with xerostomia. Twenty patients used a lactoperoxidase-system-containing toothpaste (Biotene) combined with the use of a mouthrinse (Biotene), comprising also lysozyme and lactoferrin, for 4 weeks. Saliva samples were collected at base line, after 4 weeks' use of the products, and at the end of a 4-week washout period. Samples were analyzed for selected biochemical and microbiologic factors. The effects on subjective oral symptoms were also recorded. A 4-week daily use of toothpaste and mouthrinse relieved the symptoms of oral dryness in 16 patients. The levels of salivary hypothiocyanite, lysozyme, lactoferrin, or myeloperoxidase activity did not change, but there was a significant decrease in salivary pH (P < 0.05), total peroxidase activity (P < 0.05), and total protein content (P = 0.01). In patients with the lowest salivary flow rates (n = 5) a significant (P > or = 0.04) increase was detected in salivary hypothiocyanite concentrations. No major changes occurred in salivary microflora. The products relieved subjective oral symptoms in most xerostomic patients, but this was not necessarily related to the presence of antimicrobial agents.
The highs and lows of beta activity in cortico‐basal ganglia loops (2014)

Oscillatory activity in the beta (13-30 Hz) frequency band is widespread in cortico-basal ganglia circuits, and becomes prominent in Parkinson's disease (PD). Here we develop the hypothesis that the degree of synchronization in this frequency band is a critical factor in gating computation across a population of neurons, with increases in beta band synchrony entailing a loss of information-coding space and hence computational capacity. Task and context drive this dynamic gating, so that for each state there will be an optimal level of network synchrony, and levels lower or higher than this will impair behavioural performance. Thus, both the pathological exaggeration of synchrony, as observed in PD, and the ability of interventions like deep brain stimulation (DBS) to excessively suppress synchrony can potentially lead to impairments in behavioural performance. Indeed, under physiological conditions, the manipulation of computational capacity by beta activity may itself present a mechanism of action selection and maintenance.
