On the performance of full duplex wireless networks (2013)

Half duplex radios use two separate frequency bands to enable simultaneous transmission and reception. Recently, full duplex radio that allows a wireless node to transmit and receive simultaneously in one frequency band was proposed. We propose a MAC protocol for full duplex radio networks, FDMAC, which is a simple and efficient protocol compatible with IEEE 802.11 MAC protocol. We analyze the performance of full duplex wireless networks with FD-MAC considering both the physical layer and the MAC layer.
A Role for Platelet-Derived Growth Factor in Drug-Induced Chronic Ergotism? (1995)

Generalized vasoconstriction in chronic ergot poisoning is attributed both to the ergotamine activity on alpha-adrenergic receptors and to its direct action on vascular smooth muscle cells. The authors propose that endothelial wall, chronically damaged by ergot alkaloids, releases platelet-derived growth factor (PDGF), which contributes to vasoconstriction and promotes further arterial obstruction. Their hypothesis is supported by the increased PDGF activity found in plasma of a patient suffering from chronic ergotism.
The Effect of processing on the content and composition of free sterols and sterol esters in soybean oil (1979)

Abstract The content and composition of free sterols and sterol esters in crude soybean oil and in oils from different stages of two continuous refining systems were determined. The sterols were isolated by preparative thin layer chromatography and analyzed by gas chromatography with cholesterol as an internal standard. The free sterols in one of the degummed oils amounted to 3.1 mg/g and were diminished to 1.8 mg/g oil by the De Laval Short‐Mix refining process. The content of free sterols of the other degummed oil was reduced from 3.4 to 1.6 mg/g oil by the Zenith process. The greatest reduction of sterol content was caused by the treatment with bleaching earth. The sterol esters accounted for 0.6 mg/g of the degummed oil, and only very small changes were observed during the processes. However, changes in the composition of fatty acids of the sterol esters were found. These changes might indicate a selective deacylation of sterol esters or an interesterification during the refining processes. The composition of sterols in free and esterified form were different. Campesterol, stigmasterol and sitosterol were obtained in both free and esterified form, but Δ7 stigmasterol was only found in esterified form. Only small changes in the percentage distribution of the sterols occurred during the processes.

Structural determination of <b><i>N</i></b>‐linked glycans by matrix‐assisted laser desorption/ionization and electrospray ionization mass spectrometry (2005)

This paper reviews methods for the analysis of N-linked glycans by mass spectrometry with emphasis on studies conducted at the Oxford Glycobiology Institute. Topics covered are the release of glycans from sodium dodecyl sulphate-polyacrylamide gel electrophoresis gels, their purification for analysis by mass spectrometry, methods based on matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization for producing fragment ions, and details of their fragmentation. MALDI mass spectrometry provided a rapid method for profiling neutral N-linked glycans as their [M + Na](+) ions which could be fragmented by collision-induced decomposition to give spectra containing both glycosidic and cross-ring fragments. Electrospray ionization mass spectrometry was more versatile in that it was relatively easy to change the type of ion that was formed and, furthermore, unlike MALDI, electrospray did not cause extensive loss of sialic acids from sialylated glycans. Negative ions formed by addition of anions such as chloride and, particularly, nitrate, to the electrospray solvent were stable and enabled singly charged ions to be obtained from larger glycans than was possible in positive ion mode. Fragmentation of negative ions followed specific pathways that defined structural details of the glycans that were difficult to obtain by classical methods such as exoglycosidase digestion.
Wavelet Based Fingerprint Liveness Detection (2014)

Fingerprint verification is one of the most reliable personal identification methods. It plays a very important role in forensic and civilian applications. In this paper we propose a simple and effective approach for fingerprint liveness detection based on the wavelet analysis of the finger tip surface texture. In present situation, manual fingerprint verification is so tedious, time-consuming, expensive and incapable of meeting today’s increasing performance requirements. Wavelet transform which has wide range of applications such as image compression, denoising noisy data, texture classification, etc., is used for fingerprint verification. Experimental results show that our method can successfully differentiate live finger tips from fake finger tips made of most commonly used material in fingerprint spoofing.
Skin Ageing: Natural Weapons and Strategies (2013)

The fact that the skin is the most visible organ makes us aware of the ageing process every minute. The use of plant extracts and herbs has its origins in ancient times. Chronological and photo-ageing can be easily distinguished clinically, but they share important molecular features. We tried to gather the most interesting evidence based on facts about plants and plant extracts used in antiaging products. Our main idea was to emphasize action mechanisms of these plant/herbal products, that is, their "strategies" in fighting skin ageing. Some of the plant extracts have the ability to scavenge free radicals, to protect the skin matrix through the inhibition of enzymatic degradation, or to promote collagen synthesis in the skin. There are some plants that can affect skin elasticity and tightness. Certainly, there is a place for herbal principles in antiaging cosmetics. On the other hand, there is a constant need for more evaluation and more clinical studies in vivo with emphasis on the ingredient concentration of the plant/herbal products, its formulation, safety, and duration of the antiaging effect.
PERFORMANCE OF COMPRESSOR DRIVEN METAL HYDRIDE COOLING SYSTEMS UNDER DIFFERENT OPERATING CONDITIONS (2004)

The performance of a compressor driven metal hydride cooling system is analyzed using a mathematical model which takes into account the transient nature of the compressor, conditioned space and the external fins in the reactor tubes. The design is first optimized to satisfy a given comfort and pulldown criterion at an ambient temperature of 32 0 C. Results are obtained to study the performance of the system at higher ambient temperatures. It is observed that the coefficient of performance of the system decreases with an increase in ambient temperature whereas the reverse trend is exhibited for average specific power. It is also noted that though reasonable comfort temperatures are obtained in the conditioned space with rise in ambient temperatures, there is a drastic rise in the operating pressures of the system. The study also predicts the effect of change in compressor speed, speed of the blowers and cycle time on the performance of the system under extreme operating temperatures. It is observed that controlling speed of the blowers is the most effective technique to enhance the performance.
Complicaciones mecánicas del abordaje venoso profundo en una unidad de cuidados intensivos (1999)

Se realizó un estudio de 266 cateterismos centrovenosos percutáneos a 210 pacientes ingresados en la Unidad de Ciudados Intensivos Pediátricos del Hospital Pediátrico Provincial Docente de Sancti Spíritus, en un período de 2 años, y se detectaron 20 complicaciones mecánicas que representaron el 7,5 % de los casos. Los niños comprendidos entre 5 y 14 años fueron los que con mayor frecuencia presentaron complicaciones, y fue el acceso venoso por vía yugular el de mayor tanto por ciento. Ninguna de estas complicaciones resultó fatal. Se estima que este estudio pudiese ayudar a continuar introduciendo la utilización del abordaje centrovenoso percutáneo en el manejo del paciente pediátrico grave, sobre la base criterios rigurosos y valorando riesgos y beneficios que este proceder pueda reportar.<br>A study of 266 central venous percutaneous catheterizations that were performed among 210 patients admitted at the Pediatric Intensive Care Unit of the Provincial Pediatric Teaching Hospital, in Sancti Spiritus, in a period of 2 years, was conducted. 20 mechanical complications were found that accounted for 7,5 % of the cases. Children aged 5-14 had complications more frequently. The jugular venous approach got the highest percent. None of these complications was fatal. It is estimated that this study could help to continue introducing the use of central venous percutaneous approach into the management of the severe pediatric patient on the basis of rigorous criteria, and assessing the risks and benefits this procedure may have.
MediSign: using a web-based SignOut System to improve provider identification. (1999)

Continuity of care necessitates communication between the primary providers of inpatient and outpatient care. Communication requires identification of providers in addition to clinical information. We have constructed a web-based SignOut System to improve provider identification. The web-based SignOut System correctly identified the provider for 100% (34/34) of patients in 1997 and 93% (37/40) of patients in 1998. The hospital bed census correctly identified the attending provider for 50% (17/34) of patients in 1997 and 73% (29/40) in 1998. When analyzed by attending type (i.e., service and private,) the SignOut System correctly identified 86% of service providers in contrast to the hospital bed census that correctly identified 57% of service providers. Both the SignOut System (100%) and the hospital bed census (95%) had superior results in identifying private attendings. The web-based technology provides a familiar user interface and ubiquitous workstation access.
The assessment of learning processes: some African data (1994)

Data based on responses of 218 Kenyan and 270 Zimbabwean 14-15 year old secondary school students shows the Learning Process Questionnaire (LPQ; Biggs, 1987) to be fairly reliable, factorially valid, and to correlate with self-esteem and locus of control much as expected. Comparison with like-aged students from Australia and Nigeria calls into question the stereotype that students from African countries are more prone to surface learning strategies than Western students.

<title>Airborne seeker evaluation and test system</title> (1991)

The Airborne Seeker Evaluation Test System (ASETS) is an airborne platform for development, test, and evaluation of air-to-ground seekers and sensors. ASETS consists of approximately 10,000 pounds of equipment, including sixteen racks of control, display, and recording electronics, and a very large stabilized airborne turret, all carried by a modified C- 130A aircraft. The turret measures 50 in. in diameter and extends over 50 in. below the aircraft. Because of the low ground clearance of the C-130, a unique retractor mechanism was designed to raise the turret inside the aircraft for take-offs and landings, and deploy the turret outside the aircraft for testing. The turret has over 7 cubic feet of payload space and can accommodate up to 300 pounds of instrumentation, including missile seekers, thermal imagers, infrared mapping systems, laser systems, millimeter wave radar units, television cameras, and laser rangers. It contains a 5-axis gyro-stabilized gimbal system that will maintain a line of sight in the pitch, roll, and yaw axes to an accuracy better than +/- 125 (mu) rad. The rack-mounted electronics in the aircraft cargo bay can be interchanged to operate any type of sensor and record the data. Six microcomputer subsystems operate and maintain all of the system components during a test mission. ASETS is capable of flying at altitudes between 200 and 20,000 feet, and at airspeeds ranging from 100 to 250 knots. Mission scenarios can include air-to-surface seeker testing, terrain mapping, surface target measurement, air-to-air testing, atmospheric transmission studies, weather data collection, aircraft or missile tracking, background signature measurements, and surveillance. ASETS is fully developed and available to support test programs.

Seismic validation of reservoir simulation using a shared earth model (1996)

This paper concerns an example of cross-disciplinary integration: the use of seismic modelling based on a shared earth model to validate reservoir simulation. Whole-field simulator models and finer-scale sector models can be generated from the same detailed geological description in a shared earth model, ensuring that they are consistent. However, it is possible for some aspects of the simulation to depart from the geology, making predictions unreliable. For seismic validation, synthetic seismic volumes are produced from a shared earth model containing fluid data fed back from the simulator. Features in the synthetic which are caused by fluid movements, are then looked for on the real 3D seismic data. If the seismic data confirm the simulator's results in the spaces between history-matched wells, greater confidence can be had in its forward predictions. The methodology is illustrated using the Magnus oil field in the UK North Sea.
Diozonides from Coozonolyses of Cyclodienes and Carbonyl Compounds (2002)

Treatment of conjugated cyclodienes (5a-5c) with excess ozone in dichoromethane in the presence of added carbonyl compounds (3) resulted to give the corresponding diozonides 10 and cross-ozonides 14. Similarly, ozonolysis of the nonconjugated 1,4-cyclohexadiene (6a) and 1,5-cyclooctadiene (6b) under same conditions afforded both diozonides 20 and cross-ozonides 14. On the other hand, Ozonolysis of bicyclo[2.2.0]hepta-2,5-diene (6c) in the presence of 3A provided the corresponding diozonide 19.
Data-driven prognostics based on health indicator construction: Application to PRONOSTIA's data (2013)

Failure prognostics can help improving the availability and reliability of industrial systems while reducing their maintenance cost. The main purpose of failure prognostics is the anticipation of the time of a failure by estimating the Remaining Useful Life (RUL). In this case, the fault is not undergone and the estimated RUL can be used to take appropriate decisions depending on the future exploitation of the industrial system. This paper presents a data-driven prognostic method based on the utilization of signal processing techniques and regression models. The method is applied on accelerated degradations of bearings performed under the experimental platform called PRONOSTIA. The purpose of the proposed method is to generate a health indicator, which will be used to calculate the RUL. Two acceleration sensors are used on PRONOSTIA platform to monitor the degradation evolution of the tested bearings. The vibration signals related to the degraded bearings are then compared to a nominal vibration signal of a non-degraded bearing (nominal bearing). The comparison between the signals is done by calculating a correlation coefficient (which is considered as the health indicator). The values of the calculated correlation coefficient are then fitted to a regression model which is used to estimate the RUL.
Key Management in Cryptographic Access Control (2006)

This thesis project is a part of the CryptoOS project, where cryptographic access control methods are used to replace traditional access control mechanisms. This provides a truly decentralised design, where access is not related to users, but to the possession of cryptographic keys. By using a combination of symmetric and asymmetric encryption it is possible to differentiate access to three levels: Full-, read- and integrity check authorisation. The integrity check authorisation provides the possibility to verify the integrity of data, without knowing its actual contents. This makes it possible to store confidential data on less trustworthy file servers, which only can verify the integrity of the data, and not learn its contents.
 Each file has a key, which is used to gain access to the file. These keys are collected in key rings, which provide the possibility to form different access control models. To handle the key rings and demonstrate the proposed design a key managing application and different types of servers has been implemented and evaluated. The implementation proofs that it is possible to use cryptographic access control to replace existing access control mechanisms. The performance is a bit slower than traditional models, but the overall security is increased and the design is completely decentralised and scalable, which usually requires a lot more computations.
Analysis of LDGM and compound codes for lossy compression and binning (2006)

Recent work has suggested that low-density generator matrix (LDGM) codes are likely to be effective for lossy source coding problems. We derive rigorous upper bounds on the effective rate-distortion function of LDGM codes for the binary symmetric source, showing that they quickly approach the rate-distortion function as the degree increases. We also compare and contrast the standard LDGM construction with a compound LDPC/LDGM construction introduced in our previous work, which provably saturates the rate-distortion bound with finite degrees. Moreover, this compound construction can be used to generate nested codes that are simultaneously good as source and channel codes, and are hence well-suited to source/channel coding with side information. The sparse and high-girth graphical structure of our constructions render them well-suited to message-passing encoding.

Patterned acquisition of skin barrier function during development (1998)

Skin barrier function is conferred by the outer layer of epidermis, the stratum corneum, and is essential for terrestrial life. Quantitative trans-epidermal water loss assays show that barrier forms late in embryogenesis, permitting the foetus to survive a terrestrial environment at birth. Using qualitative in situ assays for skin permeability, we show that barrier forms in a patterned manner late in mouse gestation. Barrier forms at specific epidermal sites, then spreads around the embryo as a moving front. The moving front of permeability change is accompanied by multiple changes in the outer, stratum corneum-precursor cells. We use the permeability assays to show that final stages of cornified envelope assembly are coordinated with initial stages of barrier formation. Hence the whole-mount permeability assays record developmental acquisition of a known, essential component of the adult barrier. We demonstrate the authenticity of the whole-mount assays after maternal glucocorticoid therapy (known to accelerate barrier formation) and in additional species including the rat where barrier formation is well characterized by TEWL assay (Aszterbaum, M., Menon, G. K., Feingold, K. R. and Williams, M. L. Pediatr. Res. 31, 308-317). The demonstration of patterned barrier formation in other species suggests patterned change as the universal mode of embryonic barrier acquisition. These results highlight the importance of patterning as a mode of epidermal maturation during development.
Synthesizing testability features into a design with the Synopsys Test Compiler (2002)

In this paper, we present a methodology for synthesizing testability features in a design described using Hardware Description Language (HDL) and the Synopsys Test Compiler tool. Because an HDL described design of an IC device can be automatically transformed into a gate-level implementation for a given technology with Synopsys Synthesis Tools, adding internal scan test circuitry or boundary scan test circuitry can be easily achieved with the Synopsys Test Compiler. We will discuss scan styles, test methodologies, test pattern generation, as well as the application and format of test patterns.

Global stability of discrete-time recurrent neural networks with impulse effects (2008)

This paper formulates and studies a class of discrete-time recurrent neural networks with impulse effects. A stability criterion, which characterizes the effects of impulse and stability property of the corresponding impulse-free networks on the stability of the impulsive networks in an aggregate form, is established. Two simplified and numerically tractable criteria are also provided.
