High-temperature superconductivity space experiment: passive millimeter wave devices (1991)

The Naval Research Laboratory (NRL) is exploring the feasibility of deploying high temperature superconductivity (HTS) devices and components in space. A variety of devices, primarily passive microwave and millimeter wave components, have been procured and will be integrated with a cryogenic refrigerator system and data acquisition system to form the space package, which will be launched late in 1992. This Space Experiment will demonstrate that this technology is sufficiently robust to survive the space environment and has the potential to significantly improved space communications systems. The devices for the initial launch (HTSSE-I) have been received by NRL and evaluated electrically, thermally and mechanically and will be integrated into the final space package early in 199 1 . The performance of the devices will be summarized and some potential applications of HTS technology in space system will be outlined.
Design of multilevel coded M-ary CPFSK systems with modulation index 1/2 (2002)

In this paper, based on multilevel coding and multistage decoding techniques, multilevel schemes for M-ary continuous phase frequency shift keying (CPFSK) with modulation index 1/2 are introduced. At each level of the multilevel system classical or punctured convolutional codes and at the last level, where the phase continuity is satisfied, fast frequency shift keying (FFSK) codes are used. The new systems with M=4, 8 and 16 are compared with corresponding previously designed schemes and uncoded cases. It is shown that the proposed systems have coding gain and decoding complexity advantages.
Human ultralente insulin: a comparison with porcine lente insulin as a twice-daily insulin in insulin-dependent diabetic patients with fasting hyperglycaemia. (1986)

Six C-peptide-deficient diabetic patients, selected because of raised fasting blood glucose concentrations, participated in a randomised cross-over trial comparing twice-daily porcine soluble plus human ultralente with porcine soluble plus porcine lente insulins. As out-patients, overall mean blood glucose concentrations before and after breakfast were significantly lower during human ultralente therapy (7.2 +/- 0.8 vs 12.0 +/- 1.3, 11.1 +/- 1.0 vs 14.3 +/- 1.0 mmol/l, p less than 0.05), but were unchanged for the rest of the day. During overnight in-patient metabolic profiles a nadir in blood glucose occurred between 2-4 am with both insulin regimens (5.2 +/- 0.9 mmol/l ultralente, 6.5 +/- 1.3 mmol/l lente). Mean fasting and post-breakfast blood glucose levels were significantly lower with human ultralente as were fasting concentrations of glycerol and non-esterified fatty acids (p less than 0.05). Patients with poor overnight metabolic control and raised fasting blood glucose concentrations may benefit from human ultralente insulin, used as part of their twice-daily insulin regimen.
Dynamic Response of a Metal and a CMC Turbine Blade During a Controlled Rub Event Using a Segmented Shroud (2014)

Ceramic matrix composites (CMCs) provide several benefits over metal blades including weight and increased temperature capability, and have the potential for increased engine performance by reduction of the cooling flow bled from the compressor and by allowing engines to run at higher turbine inlet temperatures. These CMC blades must be capable of surviving fatigue (high cycle and low cycle), creep, impact, and any tip rub events due to the engine missions or maneuvers that temporarily close blade tip/shroud clearances. As part of a cooperative research program between GE Aviation and the Ohio State University Gas Turbine Laboratory, OSU GTL, the response of a CMC stage 1 low-pressure turbine blade has been compared with the response of an equivalent metal turbine blade using the OSU GTL large spin-pit facility (LSPF) as the test vehicle. Load cells mounted on the casing wall, strain gages mounted on the airfoils, and other instrumentation are used to assess blade tip rub interactions with a 120-deg sector of a representative turbine stationary casing. The intent of this paper is to present the dynamic response of both the CMC and the metal blades with the turbine disk operating at design speed and with representative incursion rates and depths. Casing wear and blade tip wear are both characterized for several types of rub conditions including a light, medium, and heavy rub at room temperature. For each condition, the rub primary dynamic modes have been evaluated, and the corresponding blade tip loads have been calculated. The preliminary results suggest that a CMC blade has similar abilities to a metal blade during a rub event.
A Markov chain collaborative filtering model for course enrollment recommendations (2016)

In this paper we detail our initial approach and early results in examining the efficacy of a Markovbased stochastic model to course enrollment recommendations. We outline a Markov-based collaborative filtering model to recommend courses to students at each semester based on the sequence of courses they have taken in the previous semesters. The proposed model is based on the enrollment data and no prior knowledge of the institution, course prerequisites, curriculum or degree requirement is assumed. Using enrollment data from a research university in Canada, we evaluate and compare the Markov model with traditional collaborative filtering approaches for course recommendation. Our initial results show that the Markov-based model significantly outperforms traditional collaborative filtering models when applied to course enrollment recommendation.
The Immunobiology of T Cells with Invariant gammadelta Antigen Receptors (1991)

T cells bearing specific gamma delta TCR are the major lymphoid population in certain epithelial tissues. There are striking differences between these and peripheral T cells. The epithelial gamma delta T cells exhibit highly restricted V gene use, preferential pairing of TCR chains, and lack of diversity at the junctions creating populations of cells with virtually identical TCR in particular epithelia. Generation of certain epithelial gamma delta populations appears to be restricted to a discrete stage early in development. The restricted localization and expression of invariant antigen receptors may equip the epithelial gamma delta T cells to perform specialized functions which differ from those of circulating alpha beta and gamma delta TCR+ cells. This review provides a summary of the characterization of gamma delta T cells found in epithelial tissues and speculates on the in vivo role of these cells.
Mediators as Walrasian Auctioneers (2004)

This article opens up mediation to systematic economic analysis by considering mediators as analogous.to the Walrasian auctioneers of exchange theory. By altering trade-off rates among bargaining issues, mediators facilitate a process leading towards Pareto efficient voluntary settlements.
Gate resistance modeling of multifin MOS devices (2005)

This letter studies the effects of geometrical parameters (fin spacing, fin height and polysilicon thickness) on the gate resistance of multifin MOS devices. An effective lumped resistance model derived from distributed RC network is formulated and verified using a two-dimensional simulator. Based on the model, a design guideline for the fin spacing to minimize the gate resistance and RC delay is provided to design multifin MOS devices for high frequency applications.
Real Time Elastic Cloud Management for Limited Resources (2011)

An Infrastructure-as-a-Service (IaaS) provider is usually assumed to own a large data centre with significant computational resources. For a small or medium sized Internet Data Centre (IDC), offering cloud computing service is a nature of business model but there are technical barriers which need to be resolved. One of the key issues is ineffective resource management given such an IDC usually has only limited resource. In this paper, we propose an efficient resource management solution specially designed for helping small and medium sized IaaS cloud providers to better utilise their hardware resources with minimum operational cost. Such an optimised resource utilisation is achieved by a well-designed underlying hardware infrastructure, an efficient resource scheduling algorithm and a set of migrating operations of VMs.
Repulsion by Slit and Roundabout prevents Shotgun/E-cadherin–mediated cell adhesion during <i>Drosophila</i> heart tube lumen formation (2008)

During Drosophila melanogaster heart development, a lumen forms between apical surfaces of contralateral cardioblasts (CBs). We show that Slit and its receptor Roundabout (Robo) are required at CB apical domains for lumen formation. Mislocalization of Slit outside the apical domain causes ectopic lumen formation and the mislocalization of cell junction proteins, E-cadherin (E-Cad) and Enabled, without disrupting overall CB cell polarity. Ectopic lumen formation is suppressed in robo mutants, which indicates robo's requirement for this process. Genetic evidence suggests that Robo and Shotgun (Shg)/E-Cad function together in modulating CB adhesion. robo and shg/E-Cad transheterozygotes have lumen defects. In robo loss-of-function or shg/E-Cad gain-of-function embryos, lumen formation is blocked because of inappropriate CB adhesion and an accumulation of E-Cad at the apical membrane. In contrast, shg/E-Cad loss-of-function or robo gain-of-function blocks lumen formation due to a loss of CB adhesion. Our data show that Slit and Robo pathways function in lumen formation as a repulsive signal to antagonize E-Cad-mediated cell adhesion.
Some Diagnostic Methods for Cox Regression Models Through Hazard Smoothing (1990)

In this paper some graphical methods are proposed for evaluating the fit of Cox regression models in survival analysis. The simplest procedure proposed is to estimate the baseline hazard separately within subgroups by applying kernel-based smoothing to standard cumulative hazard estimates. The different estimates should be the same, to within sampling variability, when the model is correct. A modification of this procedure gives a direct way of calculating smooth estimates of hazard ratios over time. A further modification gives estimates of ratios as a function of a continuous covariate and time. The methods are applied to data taken from a clinical trial of adjuvant therapy for breast cancer.
Visible light communication using wavelength division multiplexing for smart spaces (2012)

LED lights used mainly for illumination purpose, can be simultaneously used for data transmission. In this paper, a visible light communications system is proposed that employs wavelength division multiplexing, to transmit multiple data streams from different data sources simultaneously, over the wireless channel. Successful implementation of a low cost prototype system is reported. The effect of ambient noise on system performance is studied. On the basis of empirical results, performance evaluation of proposed solution is presented.
Dose-related Methoxyflurane Nephrotoxicity in Rats (1972)

Dose-related nephrotoxicity after administration of methoxyflurane was demonstrated in rats of the Fischer 344 strain. This was characterized by Pitressin-resistant polyuria, hypernatremia, serum hyperosmolality, and increased serum urea nitrogen and inorganic fluoride concentrations. Urinary sodium
New technology to assess sleep apnea: wearables, smartphones, and accessories (2018)

Sleep medicine has been an expanding discipline during the last few decades. The prevalence of sleep disorders is increasing, and sleep centers are expanding in hospitals and in the private care environment to meet the demands. Sleep medicine has evidence-based guidelines for the diagnosis and treatment of sleep disorders. However, the number of sleep centers and caregivers in this area is not sufficient. Many new methods for recording sleep and diagnosing sleep disorders have been developed. Many sleep disorders are chronic conditions and require continuous treatment and monitoring of therapy success. Cost-efficient technologies for the initial diagnosis and for follow-up monitoring of treatment are important. It is precisely here that telemedicine technologies can meet the demands of diagnosis and therapy follow-up studies. Wireless recording of sleep and related biosignals allows diagnostic tools and therapy follow-up to be widely and remotely available. Moreover, sleep research requires new technologies to investigate underlying mechanisms in the regulation of sleep in order to better understand the pathophysiology of sleep disorders. Home recording and non-obtrusive recording over extended periods of time with telemedicine methods support this research. Telemedicine allows recording with little subject interference under normal and experimental life conditions.

Particular attention is also focused on the hydrocarbon activation process and on the main factors governing catalytic efficiency. Finally, after some general conclusions, future trends are analyzed.
Play in the community — quality care for the child with cancer (2004)

Play, the universal language of children, is an important child-centred communication tool and is a necessity for a sick child. Play can help the child with cancer understand and prepare for the particular type of treatment they face and can also reduce distress and anxiety for the child’s family. As more childhood cancer care moves away from the hospital setting and into the child’s own home, service providers must develop the role of specialist play in the community.
Is the aged rat ear more susceptible to noise or styrene damage than the young ear? (2003)

Noise- and styrene-induced hearing and hair cell loss were studied in young (3 months) and aged (24-26 months) Long-Evans rats. The animals were exposed 6 h/d, 5 d/w for 4 weeks to (a) broadband noise centered at 8 kHz (92 or 97dB SPL), or b) styrene (700 ppm). Auditory sensitivity was tested by recording evoked potentials from the inferior colliculus. Histological analyses of the organ of Corti, stria vascularis, and the spiral ganglions were also performed. Aged controls showed outer hair cell (OHC) loss at the basal and apical regions of the organ of Corti, and an increase in pigmentation concomitant to a decrease in vascularization of the stria vascularis, along with elevated thresholds relative to young controls. The 92-dB noise caused similar threshold shifts in both age groups, whereas the 97-dB noise caused more threshold shifts in the aged group compared to the young group. Recovery of the hearing thresholds depended both on the intensity of the noise and on the age of the animals. Aged rats had minimal hair cell loss as a result of styrene exposure, whereas young animals showed significant OHC loss, particularly in third row. Despite significant loss of OHCs, the young subjects showed styrene-induced threshold shifts only at high frequencies. In summary, the data show that : (a) there is an influence of age on both noise-induced and styrene-induced threshold shift and hair cell loss in rats and (b) the cochlea appear to have a redundancy in the number of OHCs, thus threshold shift does not necessarily occur with significant OHC loss.
KiRTi: A Blockchain-Based Credit Recommender System for Financial Institutions (2020)

In this paper, we propose KiRTi, a deep-learning-based credit-recommender scheme for public blockchain to facilitate smart lending operations between prospective borrowers (PB) and prospective lenders (PL) to eliminate the need of third party credit-rating agencies (CRAs) for credit-score (CS) generation. Thus loan grants to PB from PL is secured, authorized, and automated so as to expedite the disbursement process. KiRTi stores PB historical transactions, current assets, and liabilities as time-series sequenced data in a public blockchain. The sequenced data is fetched from blockchain by a long-short term memory (LSTM) model that generates CS for loan recommendations based on proposed lending algorithms for PB and PL. To ensure real-time updation of CS, edge-weights are updated based on boolean indicators from PB and PL, which indicates the successful repayments and loan-defaults. The process is iterated to improve the accuracy of edge-weights and generated CS to ensures the correct credibility of PB for future lending. Smart contracts (SC) are proposed for automatic setup of loan repayments between PB and PL. To model the LSTM recommender scheme, a German credit dataset from UCI repository is considered with 1000 credit-histories of PB, with 700 successful repayments and 300 defaults. KiRTi achieves an accuracy of 97.5% in comparison to conventional approaches with an F-measure of 0.98304. The security evaluation of KiRTi shows that it has computation cost of 20.96 ms and communication cost of 121 bytes compared to other state-of-the-art approaches.
Cloud service recommendation and selection for enterprises (2012)

The standardization of cloud services makes it possible to have one cloud service management platform for customers to take advantage of their subscriptions from various cloud providers. One immediate benefit lies in the way that enterprise customers may have plenty of choices of available providers, when seeking cloud services to fulfill their criteria, such as price or Service Level Agreement (SLA). However, how to select appropriate cloud offerings in terms of business requirements and company policies becomes challenging and non-trivial, especially when a composition of multiple services are to be chosen for achieving business goals. In this paper, a systematic framework on top of a hybrid cloud management platform is proposed for enterprises to automatically recommend and select cloud services according to business requirements, company policies and standards, and the specifications of cloud offerings.
Single DC/AC CCFL Inverter for Large Size LCD TV with Burst Control (2006)

Currently, dual AC voltage sources are used in the large size LCDTV to drive long and straight CCFLs. These dual AC voltage sources are out-off phase and are applied to the two sides of CCFL to overcome non-uniformity problem. But, higher cost is the penalty of this solution. This paper presents a novel CCFL inverter driver technology for large size LCDTV. The proposed burst control technology is capable to driving 950mm length or even longer CCFL by single voltage source. The luminance of lamp output is above 80% uniformity. Due to the negative incremental resistance of the CCFL, the leakage current flowing through the parasitic capacitor can be efficiently reduced with the proposed control scheme. Finally, a 42-inch LCD TV CCFL inverter is implemented experimentally to demonstrate the high efficacy and uniform luminance of the backlight system
Inhibition of neutrophil elastase activity by phenolic compounds from plants. (2001)

The influence of 40 phenolic compounds from plants were tested on the enzymatic activity of neutrophil elastase (EC 3.4.21.37). Among the flavonoids especially the compounds with a catecholic structure showed a strong inhibitory activity in the range of mumol/l, hyperosid was the strongest inhibitor with an IC50 of about 0.3 mumol/l. Lipophilic caffeic acid esters and phenolic compounds with catecholic structure elements in general inhibited the enzyme. Because of the specific role of neutrophil elastase in the inflammatory process its inhibition by phenolic natural compounds might be one explanation for the use of medicinal plants containing phenolic compounds in the treatment of inflammation.
Tumor necrosis factor induction of endothelial cell urokinase-type plasminogen activator mediated proteolysis of extracellular matrix and its antagonism by gamma-interferon (1992)

Abstract Tumor necrosis factor (TNF) has a profound capacity to alter the endothelial cell phenotype that includes morphologic and functional changes that may be central for proinflammatory processes. Recent observations have indicated that TNF can promote the synthesis and secretion of urokinase plasminogen activator (uPA) in low passage human endothelial cells that normally release little uPA. In this report we have confirmed and expanded upon these initial observations in human endothelial cells and describe the ability of gamma-interferon (gamma- IFN) to inhibit TNF-induced uPA synthesis and secretion in a dose- dependent manner (0.025 to 25 ng/mL). Analysis of cell-free conditioned medium derived from gamma-IFN-treated cultures by micro-enzyme-linked immunosorbent assay (ELISA) methodologies using uPA- and plasminogen activator inhibitor type 1 (PAI-1)-specific monoclonal antibodies (MoAbs) indicate that the decrease in uPA activity observed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) zymography is a direct result of a decrease in extracellular uPA antigen and is not a consequence of increased PAI-1 antigen. These findings are supported by Northern blot analyses that indicate that gamma-IFN treatment of endothelial cells resulted in a decreased steady state level of uPA messenger RNA (mRNA) with no measurable change in PAI-1 mRNA. This inhibitory response is specific for gamma-IFN because alpha-IFN fails to elicit a similar inhibitory response. In addition, TNF augmented extracellular proteolysis of radiolabeled subendothelial extracellular matrix (ECM) in a dose-dependent manner. The observed increase in ECM degradation mediated by TNF treatment of endothelial cells was dependent on the presence of plasminogen and could be inhibited by an anticatalytic uPA MoAb implying the requirement of proteolytically active uPA in this process. gamma-IFN (25 ng/mL) treatment of endothelial cells antagonized TNF-promoted degradation of radiolabeled ECM at a concentration that completely inhibited TNF- mediated uPA expression and activity. In addition, endothelial cells treated with TNF (18 hours) displayed the ability to invade ECM and reorganize individual cells into tube-like structures that were not evident in untreated control cultures when grown on Matrigel-coated culture dishes. gamma-IFN treatment of endothelial cells propagated on Matrigel was observed to inhibit TNF-mediated ECM invasion and tube formation at concentrations that were analogous to those required for the inhibition of uPA expression and activity. In summary, these observations suggest a novel homeostatic control mechanism for endothelial cell regulation of subendothelial ECM degradation promoted by TNF and inhibited by gamma-IFN.(ABSTRACT TRUNCATED AT 400 WORDS).
