Multistep Photoinduced Electron Transfer in a Photoacceptor Terminated Molecular Triode (1990)

Abstract A molecular “triode” (3) is described containing a nonconjugatively interconnected array (D2-D1-Pa) of two potetial one-electron donor (D) moieties and a powerful photoacceptor (Pa). In a related Ldquo;diode” (2) consisting of the array D1-Pa excitation of the photoacceptor, Pa, induces charge-separation as detected by time resolved microwave conductivity (TRMC) measurements and as evidenced from the observation of charge transfer emission resulting from radiative recombination. The latter emission is quenched in the triode 3 indicating occurrence of virtually complete consecutive electron transfer from D2 to D1. Instead 3 displays a much weaker charge transfer emission at longer wavelength attributed to direct radiative recombination from D2 to Pa. Fluorescence lifetime measurements and TRMC data show that the recombination in 3 is significantly slowed down as compared to the shorter range recombination in 2.
Removal of Leukocytes from Whole Bloodand Erythrocyte Suspensions by Filtrationthrough Cotton Wool (1972)

Units of packed red cells, derived from CPD blood, were stored for 2 or 7 days at 2°C. Using the filtration method described earlier, practically all leukocytes were removed. After filtration, the erythrocyte suspensions were again stored for 2 or 7 days at 2 °C. The red cells were then labelled with Na2 51Cr04 and infused into the original donors. The survival of the red cells was determined 24 and 48 h after infusion. Comparison to the data obtained after transfusion of labelled but unfiltered packed cells derived from CPD blood and stored for 14 or 17 days in PVC bags showed no differences in viability.
Feminism in ethics (2008)

Ethics, or moral philosophy, as a field of intellectual inquiry developed in the west for well over two thousand years with minimal input from women. Women's voices have been virtually absent from western ethics until this century, as they have been from every field of intellectual endeavour. The absence of female voices has meant that the moral concerns of men have preoccupied traditional western ethics, the moral perspectives of men have shaped its methods and concepts, and male biases against women have gone virtually unchallenged within it. Feminist ethics explores the substantive effect of this imbalance on moral philosophy and seeks to rectify it.
[Use of clonidine in the prevention of alcohol withdrawal syndrome]. (1989)

Clonidine, an effective antihypertensive drug acting on central presynaptic alpha 2-adrenoreceptors, is commonly used in opiate withdrawal. There is recent evidence of advantages in using clonidine also in alcohol withdrawal. The results of a randomized study on 44 alcoholics, admitted without withdrawal symptoms, are shown. The alcohol withdrawal syndrome appeared in 50% of the patients in the placebo group and in 9% of the clonidine treated patients. Clonidine is an effective tool in the hospital preventive treatment of alcohol withdrawal.
DIRECT VOLUME RENDERING VIA 3D TEXTURES (1994)

The advent of very fast texture mapping hardware in modern graphics workstations has warranted research into rendering techniques that use texture mapping to full advantage. We have developed a new and easy to implement method for direct volume rendering that produces high-quality images at speeds approaching two orders of magnitude faster than existing techniques, on workstations with hardware support for three-dimensional texture maps. A rectilinear data set is converted into a three-dimensional texture map containing color and opacity information. In the rendering phase, the texture map is then applied to a stack of parallel planes, which effectively cut the texture into many slices. The slices are composited to form an image of the original data set. This paper describes the theory and implementation of this technique. Keywords: Computer Graphics, Scientific Visualization, 3D Texture Mapping, Direct Volume Rendering. 1 Overview Rendering speed has always been a major problem in ...

Building secure web applications with automatic partitioning (2009)

Swift is a new, principled approach to building Web applications that are secure by construction. Modern Web applications typically implement some functionality as client-side JavaScript code, for improved interactivity. Moving code and data to the client can create security vulnerabilities, but currently there are no good methods for deciding when it is secure to do so. Swift automatically partitions application code while providing assurance that the resulting placement is secure and efficient. Application code is written as Java-like code annotated with information flow policies that specify the confidentiality and integrity of Web application information. The compiler uses these policies to automatically partition the program into JavaScript code running in the client browser and Java code running on the server. To improve interactive performance, code and data are placed on the client. However, security-critical code and data are always placed on the server. The compiler may also automatically replicate code across the client and server, to obtain both security and performance.

HALAS – A Helicopter Slung Load Stabilisation and Positioning System for Cargo Handling and Rescue Hoist Operations (2012)

To support helicopter pilots during slung load operations currently a pilot assistance system called Hubschrauber-Außenlast-Assistenzsystem (HALAS) is being developed within a cooperation of the German Aerospace Centre (DLR) and iMAR Navigation GmbH. The objective of this research is the demonstration of an automatic slung load stabilisation and positioning system during flight test with DLR's research helicopter Active Control Technology / Flying Helicopter Simulator (ACT/FHS). The automatic slung load control system is being designed to extend the functionalities of the helicopter’s stability, control and augmentation system. The control system will be able to handle the challenges of rescue hoist operations. This means compensation of additional roll, pitch and yaw moments created by a significant distance of the load suspension point to the helicopter's centre of gravity and the handling of a variable cable length. To measure the slung load motion an optical-inertial sensor is being developed by iMAR Navigation GmbH. In this paper the overall system architecture of HALAS as well as the hardware integration into the ACT/FHS is explained. The optical-inertial sensor used for the slung load dynamics measurement and estimation is described in detail. Furthermore a first system analysis of a simulation model used for the later controller design is presented. The focus of the stability analysis is laid on variations of cable length, load mass and load suspension point position. The control law development process itself is not part of this paper but will be published later.
Simulation of three-dimensional stop-ion and deposited energy distributions in amorphous chalcogenide resist film by Ga ion exposure (2002)

The Monte-Carlo (MC) simulation of three-dimensional (3D) stop-ion and deposited energy distributions in amorphous chalcogenide resist film by Ga/sup +/ ion beam exposure are presented. This paper is a part of the development of 3D MC Code suited for focused ion beam (FIB) lithography. For 3D MC simulations which are based on the simulation of individual energetic ions through their successive collisions with resist constituents, both the target depth (z-direction) and the lateral distance (x- and y-direction) are divided into discrete cubic pixels with 25/spl times/25/spl times/25 /spl Aring/, nuclear scattering and stop-ion positions and ion-loss energies are summed up in these 3D pixels by /spl sim/10/sup 4/ Ga/sup +/ ion trajectories, and then 3D ion concentration and deposited energy distribution profiles are obtained by an Ga/sup +/ ion beam exposure with proper shape and dose.
Numerical simulation of 2-micron Tm-doped fibre laser (2010)

The theoretical slope efficiency and output power for the 2-micron Tm-doped silica fiber laser is presented. The rate equations are determined and solved using software Mathematica 4.0. With the published parameters as input, good agreements were achieved between the simulation results and the published results. This simulation then can be used to examine the Tm fiber laser output power and slope efficiency for a variety of fiber and pump wavelength. The model was further used to analyze the effect of many factors: pump wavelength, pump power, fiber length, Tm concentration and output FBG. The simulation results of these five factors’ effect were discussed. Then recommendation on the experiment set-up of 2-micron fiber laser for optimum output was given based on the analysis results. Recommendations on Tm fiber amplifier was given also by modifying Tm fiber laser simulation program.
Fluorescence quenching with exponential distance dependence: Application to the external heavy-atom effect (2003)

A model for fluorescence quenching with exponential distance dependence is developed and applied to external heavy-atom quenching. The systems studied are C70-bromobenzene and phenanthrene-iodide, in liquid solutions at room temperature and in rigid glasses at 77 K. The predicted parameter correlation is observed in the two systems, which correspond to two extreme and opposite situations, strong and weak quenching. A detailed analysis of the fitted parameters allows the determination of the effective Bohr radii L and of the intrinsic unimolecular rate constants for quenching at contact, k0. The unusually high value of L for the C70-bromobenzene pair is tentatively attributed to the extended size of the external part of the π orbitals of the fullerene. The room temperature quenching rate constant computed with the determined low-temperature parameters is shown to be in good agreement with the experimental one for both systems studied.
Longitudinal control system of the intermediate capacity transit system (1983)

To meet the Intermediate Capacity Transit System (ICTS) operational requirements driverless automatic longitudinal control is necessary. The Vehicle Control Centre (VCC) of the SELTRAC Automatic Train Control determines safe maximum velocities as a function of train position and safe stopping points for each train. These depend on the positions of trains, go slow zones, switches, stations, and other designated stopping points. Commanded braking rates are determined as a function of grade, being half maximum of 1 m/s <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> except for designated stopping points. The safe stopping point, maximum speed and braking rate and grade are transmitted from the VCC to each train. The Vehicle On Board Control (VOBC) on each train reports position, speed and other train information to the VCC. All computers are check redundant and all communications are protected by a redundancy code for safety. The VOBC computes braking curves for the stopping point based on a constant deceleration rate. When the train intercepts the braking curve, it goes into the constant rate deceleration mode, commanded to the speed of the braking curve as a function of its distance from the stopping point. Allowance is made in the braking curves for jerk into and out of deceleration. The Automatic Speed Control (ASC) is a closed control loop which generates motoring and regenerative braking commands to the propulsion system and blended braking commands to the disk brakes to control the train trajectories. Check-redundant tachometers and a servo accelerometer comprise the feedback elements of the ASC loop. Proportional plus integral elements provide compensation and the accelerometer provides rate feedback. The compensation and feedback elements provide close control of both transient and steady state operation. The system was developed on the TRAJCONT simulation and has been successfully tested and proven on both test and production vehicles on the Metro Canada System Test Track at Kingston, Ontario.
An Application of Gradients to Gravity and Magnetism Interpretation Discovery (1978)

When the horizontal and vertical gradients of either the magnetic or gravity fields are plotted against each other, some interesting graphs may result. In the case of the geological contact the symmetry and characteristic points of the loci can be directly related to the parameters defining the structure. The vertical gradient may be calculated from the more readily measured horizontal one by applying a Hilbert Transform. When the two derivatives of gravity over a contact are plotted against each other the graph closely resembles an ellipse. The loci of the magnetic gradients over this same body is precisely circular. In both cases the method is given for relating the characteristic points of these loci to the parameters defining the structure.
Gene therapy for colorectal cancer (2002)

Gene therapy has been developed as a potential novel treatment modality for colorectal cancer. The preclinical data have been promising and several clinical trials are under way for colorectal cancer. Data from many phase 1 trials have proven the safety of the reagents, but have not yet demonstrated significant therapeutic benefit. In order to refine this approach, continuing efforts should be made to improve the antitumour potency, efficiency of gene delivery, and accuracy of gene targeting. It is likely that gene therapy will be integrated into pre-existing therapies including surgery, chemotherapy and radiotherapy to establish its niche in tomorrow's medicine.
Acquired protein C deficiency in a patient with primary antiphospholipid syndrome. Relationship to reactivity of anticardiolipin antibody with thrombomodulin. (1989)

A 16-year-old boy had recurrent venous thromboses and pulmonary thromboembolism that caused him pulmonary hypertension. He also had livedo reticularis, thrombocytopenia and high titer IgG antiphospholipid (cardiolipin) antibodies. In the absence of clinical and laboratory evidence of SLE, he was considered to have a primary antiphospholipid syndrome. Coagulation studies revealed a functional deficiency of protein C although it was present in normal antigenic amounts. Since both his parents had normal functional and antigenic protein C findings, his deficiency was considered acquired. The reactivity of the anticardiolipin antibodies could be decreased in a dose dependent fashion when preincubated with increasing amounts of thrombomodulin, a protein required for protein C activation at the endothelial cell membrane. This interaction of antiphospholipid antibodies with thrombomodulin may help explain the occurrence of thrombosis in some patients with antiphospholipid antibodies, despite the behavior in vitro of these antibodies as circulating anticoagulants.
A High Speed Product Integrator (1953)

A method of employing the components of a high speed analog computer to evaluate product integrals is presented. Kernel functions of two variables are obtained with time as the variable of integration and the position of ganged potentiometers as the parametric variable. High speed multipliers, function generators, adders, and integrators permit the evaluation of a one-hundred point product integral curve every 1.67 seconds. This curve is displayed on a cathode-ray tube screen having a long persistence P-7 phosphor. Examples of sine and cosine transforms evaluated with the product integrator are given. The observed errors range from 1 to 10 percent, depending upon the problem.
Diggings by Feral Pigs Within the Wet Tropics World Heritage Area of North Queensland (1997)

The association of ground-digging activity of feral pigs with a range of environmental variables was examined in the wet tropics World Heritage Area of north Queensland. Approximately 4% of the surveyed ground was disturbed by digging activity of feral pigs. Significant differences in diggings were detected between highland and lowland areas and between habitat types. Diggings were more prevalent in lowland areas and coastal swamp habitats. Diggings were positively associated with roads, tracks and moist drainage lines.

Optical Glucose Sensor Based on Affinity Binding. (1983)

An optical approach has been developed for a continuous measurement of glucose in physiological environments. This approach utilizes a small length of dialysis hollow fiber as the sensing element. The hollow fiber contains a carbohydrate receptor, Concanavalin A (Con A), immobilized on its inner surface and a high molecular weight fluorescein labelled dextran as a competing lig and . A single optical fiber is inserted in one end of the hollow fiber and both ends of the hollow fiber are sealed. The dialysis fiber is freely permeable to glucose, yet is essentially impermeable to the dextran contained within its luminal space. Both glucose and dextran bind to Con A. Glucose in the medium diffuses into the sensing element and competes with dextran for binding to Con A. At equilibrium, the level of free fluorescence in the fiber lumen is measured optically via the optical fiber and is correlated to the concentration of glucose. Contrary to the present detection techniques where the measurement is based on the consumption rate of glucose in an enzymatic or electrochemical reaction, this approach works in equilibrium conditions. The sensor neither consumes the reactant nor produces any product.
Growth, steady-state, and time-resolved photoluminescence study of CdTe/MgCdTe double heterostructures on InSb substrates using molecular beam epitaxy (2013)

CdTe/MgCdTe double heterostructures (DHs) are grown on InSb substrates using molecular beam epitaxy and reveal strong photoluminescence with over double the intensity of a GaAs/AlGaAs DH with an identical layer structure design grown on GaAs. Time-resolved photoluminescence of the CdTe/MgCdTe DH gives a Shockley-Read-Hall recombination lifetime of 86 ns, which is more than one order of magnitude longer than that of typical polycrystalline CdTe films. These findings indicate that monocrystalline CdTe/MgCdTe DHs effectively reduce surface recombination, have limited nonradiative interface recombination, and are promising for solar cells that could reach power conversion efficiencies similar to that of GaAs.
Effect of microbial phytase and citric acid on phosphorus bioavailability, apparent metabolizable energy, and amino acid digestibility in distillers dried grains with solubles in chicks (2006)

Three experiments were conducted to evaluate the effectiveness of OptiPhos phytase and citric acid for releasing the P that is not bioavailable in distillers dried grains with solubles (DDGS). The effect of OptiPhos phytate on AME(n) and amino acid digestibility was also determined. New Hampshire x Columbian chicks were fed experimental diets from 8 to 21 d of age. For Experiment 1, a basal P-deficient diet contained 40% DDGS plus supplemental amino acids, and DDGS was the only source of P. The basal diet was then supplemented with 1,000 or 10,000 phytase units (FTU)/kg of OptiPhos phytase or with 0.2% of P from KH2PO4. In Experiment 2, a slope-ratio chick growth and tibia ash assay used a P-deficient soybean meal basal diet, and it was found that the bioavailability of P in DDGS was 67%. For Experiment 3, a P-deficient basal diet with 30% DDGS plus supplemental amino acids was supplemented with 0.05 or 0.1% P from KH2PO4, with 3% citric acid, or with 1,000 or 10,000 FTU/kg of OptiPhos phytase. In Experiment 1, both 1,000 and 10,000 FTU/kg of phytase increased tibia ash but had no effect on AME(n). Both 10,000 phytase units (FTU)/kg of phytase and supplemental P increased digestibility of amino acids. In Experiment 3, supplemental phytase and citric acid increased tibia ash (mg/tibia), and it was estimated that phytase and citric acid could release from 0.04 to 0.07% P from DDGS. In terms of bioavailability coefficients, the bioavailability of the P in DDGS was increased from 62 to 72%. These results indicate that phytase and citric acid increase the bioavailability of P in DDGS, but phytase at 1,000 FTU/kg had no consistent effect on AME(n) and amino acid digestibility.
A SENSE OF PLACE : GPS AND ALASKA RAIL SAFETY (2004)

The Alaska Railroad Corporation (ARRC) has implemented the first phases of a collision avoidance system (CAS) that is primarily based on real-time Global Positioning System (GPS) technology and VHF data radio communications. The objective of the system is to improve safety by preventing train-to-train collisions, protecting track maintenance forces, as well as enforcing speed limits. Additionally, the ARRC is focused on improving customer service through reduced transit time and reliable delivery under frequently adverse conditions. In the first phases, the infrastructure that was implemented established the foundation for locomotive onboard applications and dispatcher office applications. In the remaining phases, digital delivery of onboard authority, automatic enforcement of authority limits and speed restrictions, and roadway worker protection will be provided. The article discusses system control, the safety building blocks, data radio network, GPS technology, testing and heuristics, differential correction delivery, and current and future installations.
