Dose‐Ranging Study of a New, Once‐Daily Diltiazem Formulation for Patients with Stable Angina (1995)

A double-blind safety and efficacy dose-ranging study was conducted with a new, once-daily, extended-release (XR) diltiazem hydrochloride formulation (Dilacor XR, Rhône-Poulenc Rorer, Collegeville, PA) in 189 patients with chronic stable angina pectoris. After a 2-week placebo lead-in phase, the patients were randomly assigned to 1 of 4 once-daily, fixed-dose treatment groups: placebo, XR diltiazem 120 mg, 240 mg, or 480 mg. Extended-release diltiazem, at 240-mg and 480-mg once-daily doses, significantly improved (P < .05) total exercise time during treadmill exercise tolerance testing after 2 weeks of treatment when assessed 24 hours after the previous dose. These increasing doses of XR diltiazem were associated with incremental improvements in exercise tolerance. Outpatient function, as assessed by frequency of anginal attacks, nitroglycerin use, and ambulatory electrocardiogram (Holter, Scole Engineering Culver City, CA) monitoring of ischemic events, was also improved by XR diltiazem. This extended-release diltiazem formulation can be clinically titrated within the 120- to 480-mg dosing range, permitting effective once-daily administration for treating chronic stable angina.
Energy and flux limits of cold-fusion neutrons using a deuterated liquid scintillator (1990)

Deuterated liquid scintillator detectors (NE230), which give excellent n/\ensuremath{\gamma} discrimination and provide a direct measure of the neutron energy spectrum, have been used to search for 2 to 3 MeV neutrons produced in d+d cold fusion. The apparatus consisted of an electrolytic cell using high-efficiency inverted-well geometry. Several samples of annealed Pd wire and a Pd casting (up to 13 g) were studied over a period of several weeks. An upper limit of \ensuremath{\le}${10}^{\mathrm{\ensuremath{-}}3}$ fusion (n/s g) Pd was obtained corresponding to 7\ifmmode\times\else\texttimes\fi{}${10}^{\mathrm{\ensuremath{-}}24}$ fusion (n/s) dd pair in our samples which excludes most of the reported positive results. Several sources of spurious signals, which could closely mimic signals from fusion neutrons, were also observed.
Computation and performance issues In coliseum (2003)

Coliseum is a multiuser immersive remote teleconferencing system designed to provide collaborative workers the experience of face-to-face meetings from their desktops. Five cameras are attached to each PC display and directed at the participant. From these video streams, view synthesis methods produce arbitrary-perspective renderings of the participant and transmit them to others at interactive rates, currently about 15 frames per second. Combining these renderings in a shared synthetic environment gives the appearance of having all participants interacting in a common space. In this way, Coliseum enables users to share a virtual world, with acquired-image renderings of their appearance replacing the synthetic representations provided by more conventional avatar-populated virtual worlds. The system supports virtual mobility--participants may move around the shared space--and reciprocal gaze, and has been demonstrated in collaborative sessions of up to ten Coliseum workstations, and sessions spanning two continents. This paper summarizes the technology, and reports on issues related to its performance.

DEVELOPMENT OF PROTOTYPE NUCLEAR RADIATION RESISTANT ENGINE OIL. Quarterly Progress Report No. 2 for June through August 1958 (1959)

Liquid meta-linked polyphenyl ethers continue to show real promiise as potential radiation-resistant hightemperature lubricants. They have good physical properties, high minimum spontaneous iginition temperatures and are approximately equivalent to the previously examined para-linked ethers in thermal- , oxidation- and radiation stability. Their lubrication characteristics, as measured in high-temperature Four-Ball tests, are encouraging. The identity and source of unstable contaminants in conventionally prepared samples of metalinked ethers have been determined. Alternate synthetic routes to avoid formation of these impurities (ring methylated compounds) have been found. Larger samples of these liquid ethers will be prepared and used in expanded testing; especially to obtain additional imformation on their performance in high-speed gears and bearings. (auth)
Rapid immunochemical determination of plasma fibronectin with a centrifugal analyzer. (1982)

We report a turbidimetric procedure, using commercially available reagents, for the determination of plasma fibronectin with an unmodified centrifugal analyser. Fixed-time kinetic readings at 340 nm were taken at 60 and 720 s. A wide range of concentration (up to 1000 mg/l) can be measured. Precision and accuracy were quite acceptable. Correlation with radial immunodiffusion was satisfactory. This automated procedure, simple and rapid, allows extensive studies of fibronectin in various diseases.
Impact-analysis of the charging of plug-in hybrid vehicles on the production park in Belgium (2010)

Internal combustion engines (ICE) are combined with electric motors and batteries in both hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) to improve efficiency and achieve a limited all electric range. This paper determines the electrical power required for charging a fleet of PHEVs in Belgium. A stochastic model based on the driving behavior of Western European drivers, determines the availability of the PHEVs for grid charging. Three scenarios are defined to generate charging profiles based on the driving profiles. The first two scenarios, defined as uncoordinated charging, are based on a continuation of the current tariff schemes available to residential users, i.e. a single electricity tariff or a double electricity tariff including a day and night tariff. In the third scenario, coordinated charging is proposed. When coordinated charging is applied, the time of charging is shifted to a more appropriate moment of the night where total electrical load is minimal. The charging energy when coordinated charging is applied for each PHEV is defined to be equal to that of the single tariff scenario. The extra load caused by charging PHEVs is added to the residential and industrial electricity consumption of Belgium in 2008. Based on this data, a year load duration diagram can be determined to quantify demand for both power and energy in base load, variable load and peak load. Uncoordinated charging for residential users will cause difficulties for the electricity production system because peak load will rise substantially while base load stays the same. Coordinated charging is essential to minimize the impact on the electricity production system and could be implemented using smart meter technology.
FFTF Probe-Type Eddy-Current Flowmeter: Wet versus dry Performance Evaluation in Sodium (1973)

An eddy-current flowmeter (ECFM), designed to measure the velocity of coolant sodium exiting the fuel subassemblies of the Fast Flux Test Facility (FFTF) to be built at Richland, Washington, was tested in the Westinghouse Advanced Reactors Division’s General Purpose Loop No. 2 (GPL-2) during the period of October 2, 1971 to March 16, 1972. The ECFM was operated in both a wet and dry prototypic (FFTF) design test housing. In the wet design test housing, the ECFM is exposed directly to sodium; in the dry design test housing, the ECFM is shielded from sodium by a stainless-steel “thimble.” During both tests, the same ECFM electronics supply and associated wiring were used. The same ECFM electrical adjustments also were employed in both cases. Throughout the total testing period of 1351.6 h, the ECFM operated satisfactorily. No failures or malfunctions occurred in the ECFM, its power supply, or the three test thermocouples. Significantly, the data showed that the ECFM’s overall average dc output signal in the dry design was 62% of that in the wet design.
An interferometric observation of topological effect by novel axially symmetrical wave plate (2012)

Both optical vortices and polarization vortices (vectorial vortices) are known to have attracted great interest in the field of optics. Although there have been some proposals concerning axially symmetrical polarizers, also referred to as radial polarizers, axially symmetrical wave plates (AS-WPs) have not previously been proposed. Particularly, the AS-WP has strongly dependence on both the wavelength and the temperature. Moreover, the structure of AS-WPs inherently introduce spatial dispersion. As a solution to these problems, we have proposed an achromatic axially symmetrical wave plate (AAS-WP) based on Fresnel reflection that does not introduce spatial dispersion. In this paper, we show the principle of generation, the optical properties of the optical element, and the generation method of the vortex spectrum for changing the polarization order, a well-known characteristic in singularity optics Moreover, in this paper, we also describe a generation technique for a high-order optical vortex based on geometric phase and the interferometric observation of the topological effect of the proposed AAS-WP.
The Stereo-differentiating (Asymmetric) Hydrogenation of the C=O Double Bond with a Modified Nickel Catalyst. XXXV. A Facile Method for the Preparation of Optically Pure β-Diols (1980)

Abstract The hydrogenation of RCOCH2COR over a Raney nickel catalyst modified with a mixture of tartaric acid and NaBr gave (R*, R*-RCH(OH)CH2CH(OH)R selectively with a high optical purity. The substrates with R=CH3–, CH3CH2–, CH3CH2CH2–, CH3(CH2)4CH2–, and Ph– were employed in this study. In all cases, the recrystallization of the hydrogenation product gave an optically pure (R*,R*)-isomer which was free from the (R*,S*)-isomer.
Targeted vertical cross-sectional imaging with handheld near-infrared dual axes confocal fluorescence endomicroscope (2013)

We demonstrate vertical cross-sectional (XZ-plane) images of near-infrared (NIR) fluorescence with a handheld dual axes confocal endomicroscope that reveals specific binding of a Cy5.5-labeled peptide to pre-malignant colonic mucosa. This view is perpendicular to the tissue surface, and is similar to that used by pathologists. The scan head is 10 mm in outer diameter (OD), and integrates a one dimensional (1-D) microelectromechanical systems (MEMS) X-axis scanner and a bulky lead zirconate titanate (PZT) based Z-axis actuator. The microscope images in a raster-scanning pattern with a ±6 degrees (mechanical) scan angle at ~3 kHz in the X-axis (fast) and up to 10 Hz (0-400 μm) in the Z-axis (slow). Vertical cross-sectional fluorescence images are collected with a transverse and axial resolution of 4 and 5 μm, respectively, over a field-of-view of 800 μm (width) × 400 μm (depth). NIR vertical cross-sectional fluorescence images of fresh mouse colonic mucosa demonstrate histology-like imaging performance with this miniature instrument.

Comparison of daytime and nighttime oxidation of biogenic and anthropogenic VOCs along the New England coast in summer during New England Air Quality Study 2002 (2004)

Volatile organic compounds (VOCs) and some of their oxidants (O 3 , NO 3 ) were measured on board the National Oceanic and Atmospheric Administration research ship R/V Ronald H. Brown along the coast of New England, downwind of New York, Boston, and Portsmouth and large forested areas in New Hampshire, Maine, and Massachusetts in July and August 2002. The diurnal variations of isoprene, monoterpenes, and aromatics were mainly dependent on their emissions and the abundance of the oxidants OH and NO 3 . Elevated mixing ratios of short‐lived VOCs were only encountered at the ship, which was about 1–6 hours downwind of the sources, when the concentrations of the oxidants were low. For the biogenic compounds this was generally the case during morning and evening hours, when the lifetime of the biogenics was long because of low OH and NO 3 concentrations. Most anthropogenic VOCs do not react with NO 3 , and therefore their mixing ratios remained elevated during the night. The products of isoprene oxidation, methyl vinyl ketone, methacrolein, and peroxymethacrylic nitric anhydride (MPAN) were, on average, more abundant than isoprene itself. Only during the transition periods from day to night, when oxidation rates were at a minimum, could isoprene exceed its products. The loss of the biogenic VOCs was dominated by reactions with NO 3 , whereas the loss of anthropogenics came mostly from reactions with OH. The oxygenated VOCs are the major contributor to the OH loss, except in close vicinity of emission sources. The total loss of biogenic compounds during the night was so effective that after one night of transport they were in most cases completely reacted away, whereas the mixing ratios of the anthropogenic compounds remained high during the night. The pool of reactive hydrocarbons at sunrise was thus typically dominated by anthropogenic VOCs.
Preparation of thick PZT films on stainless steel substrates (2000)

Abstract Lead zirconate titanate (PZT, PbZr0.52Ti0.48O3) films of thickness 22 μm have been deposited on stainless steel substrates by spin-coating a PZT solution containing PZT powder. The solution had a concentration of 1.2 M and was dispersed with PZT powder in a 1:1 powder/solution molar ratio. The films were rapidly heated to 400°C and annealed for 15 min, and then they were further annealed in an oven at 650°C for 30 min. The results of X-ray diffraction studies show that the films have a pure perovskite phase. The inter-diffusion of ions at the PZT/stainless steel interface was prevented by using a ZrO2 barrier layer. The films were found to have good ferroelectric and piezoelectric properties.
Influence of Soil Compaction on Tunnel Network Construction by the Eastern Subterranean Termite (Isoptera: Rhinotermitidae) (2004)

Eastern subterranean termites, Reticulitermes flavipes (Kollar), workers were introduced into arenas containing low, moderate, and high compaction builder's sand (1.05 g/cm3, 1.18 g/cm3 or 1.35 g/cm3 bulk densities, respectively), and they immediately began tunneling. Termites built the tunnel network significantly fastest in soil of low compaction compared with moderately or highly compacted soil. In soil of low compaction, 221.67 +/- 4.73 cm of total tunnel distance was constructed in 1 d compared with only 96 cm of tunneling in highly compacted soil. At 14 d, total tunnel distance averaged 216.83 +/- 4.56 cm in soil of low compaction compared with 169.70 +/- 4.10 and 181.18 +/- 6.13 cm in moderately and highly compacted soil, respectively. Decreases in total tunnel distance between 1 and 14 d were caused by backfilling of seldom-used tunnels. Termites did the majority of tunneling during the first day of introduction into arenas. In soil of low and moderate compaction, termites essentially constructed the entire tunnel network within the first day, only modifying it by backfilling or maintaining tunnels. In highly compacted soil, 53% of the final tunnel network was constructed during the first day, 87% was constructed by the third day, and 97% was constructed by the seventh day. Soil compaction did not affect the number of primary tunnels or the number and diameter of secondary tunnels. The angle between the secondary tunnel and primary tunnel also was not significantly affected by soil compaction. However, the number of secondary tunnels in soil of low compaction (5.89 +/- 0.51) was significantly greater than in moderately (2.74 +/- 0.36) and highly (3.58 +/- 0.59) compacted soils.
Improved reversible LDPC codes (2005)

We provide a thorough analysis for a class of iteratively encodable low-density parity-check codes. The iterative encoding technique is based upon the graphical representation of the code and allows the decoder circuit to also be used for encoding, thus saving circuit area. The analysis identifies a weakness in the structure of the code, which arises due to a repetitive pattern in its factor graph. We show that the graph supports pseudo-codewords of low pseudo-weight, and relate this to the empirical observation of some near-codewords. We then propose a new recursive technique for constructing iteratively encodable codes which have improved expansion. The new codes offer a large amount of flexibility in the choice of code length and rate, and performance that compares well to both randomly generated and extended Euclidean-geometry codes
"Dragon in the blood"; counseling- en beeldend therapeutische module over HIV-Aids voor kinderen in de leeftijd van 8-12 jaar (2009)

De module Dragon in the Blood is een combinatie van creatieve therapie en counseling voor kinderen in de leeftijd van 8-12 jaar, die besmet zijn met HIV/Aids of in hun omgeving dagelijks met deze ziekte geconfronteerd worden. 
De kinderen van the House of Resurrection worden dagelijks geconfronteerd met ziekte en in enkele gevallen met de dood. Vanaf ca. 8 jaar worden de kinderen er zich bewust van de besmetting met HIV van henzelf of de andere kinderen. Tot nu toe bestaat er geen counseling om de kinderen te informeren en te begeleiden over de gevolgen van HIV en Aids, the Dragon in the Blood die helaas als een rode lijn door hun verdere leven zal lopen. Uiteraard kunnen zij met hun vragen terecht bij het personeel, die elk jaarlijks een training (Lifeline Counseling Course) volgen. Toch betekent dit in de praktijk dat de kinderen dit initiatief zelf moeten nemen, en dat door de drukte die het werken op de kinderafdeling met zich meebrengt (2 pedagogisch medewerkers op een groep van 22 kinderen) hier weinig aandacht aan besteed kan worden. 
Ik zie het als een groot gemis dat deze kinderen niet de professionele begeleiding krijgen die zij verdienen om om te leren gaan met de gevolgen van HIV en Aids. Deze module zal bijdragen aan de kwaliteit en professionaliteit van The House of Resurrection en sluit aan bij de visie van het huis:
Hoofddoel van de module is:Het kind is in staat zijn/haar gevoelens en gedachten over HIV/Aids te uiten, en is daardoor beter in staat om te gaan met de gevolgen van deze ziekte in het dagelijkse leven.
Dragon in the blood is a combination of art therapy and counseling for children in the age of 8-12 which are infected or affected with HIV. The module will be used at The House of Resurrection at Port-Elizabeth, South-Africa, a Haven for patients which are affected or infected with HIV or Aids. 
The care in the House of Resurrection is focused on the physical, medical, mental health and religious needs of the patients, and is being provided by careworkers and nurses. Art therapy will only be given by art therapy practicals from overseas, until now not on a regular basis. This means that this counseling module is no part of an official treatment service, but a complementation of the care provided.
Internal model control for high-speed spiral scan AFM (2015)

We report on a novel application of internal model control for accurate tracking of a high speed spiral trajectory in scanning probe microscopy. With a closed-loop bandwidth of only 1 kHz, we achieved tracking errors as low as 0.31% of the scan diameter and an ultra-video frame rate of 37.5 frames per second (FPS) for a high pitch spiral trajectory generated by amplitude modulation of 3 kHz sinusoids.
Improving the fuzzy logic controller of a car racing competition with adjusted fuzzy sets (2016)

This paper describes the improvement of the Fuzzy Logic controller that won the car racing competition 2007 in the IEEE Congress on Evolutionary Computation (CEC2007). In particular, the use of the fuzzy sets within the original fuzzy controller of Ho and Garibaldi was improved. Several simulation experiments were conducted to optimize the membership functions of the fuzzy sets. The experiments are described and results discussed. The sum of different strategies qualify for an improvement of the original controller: Rearrangement of influence parameters, symmetric membership functions, and adjusted fuzzy rules. An overall improvement of 0.5 % in the competition score compared to the original winning controller is retrieved.
Ischemic preconditioning and myocardial hypothermia in rabbits with prolonged coronary artery occlusion (1999)

This study tests whether combining regional hypothermia and ischemic preconditioning (IP) provides greater myocardial protection during prolonged coronary artery occlusion (CAO) than either intervention alone, and whether increasing the duration of IP from 5 to 7 min extends the window of protection to include a 2-h CAO. Anesthetized rabbits were randomized to four groups (n = 8 rabbits/group): control (C), hypothermia alone (H), IP alone for two 7-min episodes (IP7), and IP plus hypothermia (H + IP7). To compare differences in IP for 5 versus 7 min, additional rabbits (n = 6) received one 5-min episode of ischemia (IP5). All rabbits got 2 h of CAO and 3 h of reperfusion. In comparison with the infarct size in the control group (72 +/- 4% of the risk zone), infarct size was significantly reduced in H (50 +/- 7%), IP7 (49 +/- 5%), and H + IP7 (42 +/- 6%) (all P < 0.05 vs. control group). IP5 failed to confer protection (67 +/- 5% of the risk zone). Therefore, IP can protect against a 2-h CAO if the IP regimen is increased from 5 to 7 min. The combination therapy significantly improved regional myocardial blood flow in the previously ischemic region to a greater extent than either treatment alone.
