Radiation of difference-frequency sound generated by nonlinear interaction in a silicone rubber cylinder (1976)

In this paper we describe an experimental and theoretical investigation of the parametric signal generated in one medium, a silicone rubber cylinder, and radiated into a second medium, water. The primary waves (∠1.4 MHz) are confined to a narrow region around the axis of the cylinder and, because of the relatively high absorption at these frequencies, are largely attenuated before reaching the end of the cylinder. The silicone rubber cylinder serves two purposes. First, the low sound speed (∠1000 m/sec) and high parameter of nonlinearity (1+B/2A?5) of the silicone rubber makes the virtual sources more than seven times as strong as they would be in water. Second, because the sound speed in silicone rubber is less than that of the surrounding water, the silicone rubber cylinder acts as a slow waveguide antenna for the difference-frequency waves. The system is analyzed by numerically solving the system of equations obtained by coupling the surface Helmholtz integral equation for the interior of the silicone cylinder (which includes the virtual sourcesI with the integral equation for the region exterior to the cylinder. Experimental results obtained for difference frequencies between 10 and 20 kHz compare favorably with theory. Subject Classification: [43]25.35, [43]25.15; [43]30.75.
Preparation and Characterization of Self-Assembled Multilayers of Octadecylamine on Mica from Ethanol Solutions (2003)

Films of octadecylamine molecules on mica have been prepared from ethanol solutions and characterized by atomic force microscopy. Multilayer films are formed exposing terraces with alternating frictional and wear properties, which are assigned to methyl and amino group terminations. Micellar formation in the ethanol solution and subsequent deposition onto the mica is the proposed growth mechanism. By addition of acid, the ratio between protonated and unprotonated molecules was changed. The influence of this parameter on the structure of the terraces is also reported.
3D visualization of convection patterns in lab-on-chip with open microfluidic outlet (2009)

Open-outlet microfluidics is getting more and more attention, thanks to the generation of capillarity-driven flows which simplify the connection with the macro-world. It is known that convection flows are generated at the interface with air, i.e., the meniscus. Several works have investigated evaporation-induced convection, but its effect on particle position control in open-outlet biodevices is still not characterized. In this paper, we present the results of 3D measurement of particle traces near the meniscus in an open-outlet vertical 400 μm micro-channel filled with a water-based saline solution. Using a standard optical microscope and a system of mirrors, we observe the 3D position of individual micro-beads floating in the solution, in a way akin to particle image velocimetry technique. A single vortex is generated at the meniscus and occupies the whole region under observation at a distance of 1.5–2.7 mm from the meniscus. The generation of the convection pattern and the vortex rotational speed are described. The convection patterns disappear when evaporation is inhibited, while both the vortex generation and the rotational speed are faster for highly saline solutions. These results are relevant to the design of biochips which require control of the particle position in a fluid since they emphasize that in open-outlet microfluidic systems not only the gravitational fall but also the convection drag must be counteracted.

Exploring design patterns with the Java programming language (1998)

This project describes and discusses the concepts of design patterns giving a historical background as well as citing contributions to the software development field and current research efforts. In addition, the advantages and disadvantages of using design patterns and efforts to encourage design pattern usage in software organizations are discussed. Seven design patterns (Builder, Adapter, Composite, Template Method, Facade, Mediator and Strategy) were chosen as the basis for example concrete applications. The concrete applications are given in the form of design documentation, source code and executable software. The applications demonstrate the use of design patterns in developing object oriented software applications. The applications are implemented in the Java programming language. The Java programming language was used because it is a popular object oriented programming language. An aspect of its popularity comes from its ability to execute with Java enabled browsers on a variety of computing platforms. Noted researchers in the area of design patterns assert that design patterns are language independent, however, much of the implementation in the area of design patterns has been written in the C++ language. The contribution of this project lies in implementing selected design patterns in Java and noting experiences that support or refute the conjecture that design patterns are language independent.
Numerical study of the dynamic response of a wind turbine on a tension leg platform with a coupled partitioned six degree-of-freedom rigid body motion solver (2018)

In assessment of the response of floating wind turbines under extreme wave conditions, structure stability and survivability is of utmost importance in the design and implementation. The experimental upwind horizontal axis floating wind turbine on a tension leg platform (TLP) setup was validated with the strongly coupled partitioned six degree-of-freedom rigid body motion solver (Chow and Ng 2016). After tuning of the unknown variables such as the tendon stiffness and damping coefficients with the decay tests, the system ran with the coupled fluid-motion numerical solver resulted in accurate estimations of the natural frequencies and damping ratios. Together with a modified restrain system to model the tendons, the response of the floating wind turbine under regular and focused waves simulations were found to be well-predicted. A stability analysis was performed to determine the iterations that should be ran every time step. The median of the time steps converged within 8.7 iterations.
Spirochaeta dissipatitropha sp. nov., an alkaliphilic, obligately anaerobic bacterium, and emended description of the genus Spirochaeta Ehrenberg 1835 (2009)

A novel obligately anaerobic, mesophilic, alkaliphilic spirochaete, strain ASpC2(T), was isolated from an anaerobic sediment of alkaline, hypersaline Owens Lake in California, USA. The Gram-negative cells are motile, helical in shape and 0.23 x 8.0-18.0 mum. Growth occurs within the following ranges: 13-41 degrees C, with optimal growth at 35 degrees C; 1-3 % (w/v) NaCl, with optimal growth at 2 % (w/v) NaCl; and pH 7.8-10.5, with optimal growth at pH 10.0. The novel isolate is strictly alkaliphilic and requires high concentrations of carbonate ions in the medium. It utilizes some sugars, some organic acids, some amino acids, Casamino acids, yeast extract and peptone. The main end products of glucose fermentation are CO(2) and acetate. Strain ASpC2(T) is resistant to kanamycin and rifampicin, but sensitive to ampicillin, chloramphenicol, gentamicin and tetracycline. The DNA G+C content of the new isolate is 43.8 mol%, its genome size is 6 x 10(8) Da and the melting temperature of its genomic DNA is 71 degrees C. DNA-DNA hybridization experiments demonstrated 46 % similarity with the phylogenetically most closely related species, Spirochaeta asiatica Z-7591(T). On the basis of physiological and molecular properties, the new isolate belongs taxonomically to a novel species within the genus Spirochaeta, for which the name Spirochaeta dissipatitropha sp. nov. is proposed (type strain, ASpC2(T)=ATCC BAA-1083(T)=JCM 12856(T)). S. dissipatitropha ASpC2(T) is the second strain in the genus (after Spirochaeta smaragdinae SEBR 4228(T)) that is able to use proteolysis products as the sole energy source, and additional tests have shown that other halo-alkaliphilic spirochaetes (Spirochaeta americana, Spirochaeta alkalica and Spirochaeta africana) are also able to grow on yeast extract alone; therefore, an emended description for the genus Spirochaeta is given.

Phagocytosis in earthworms: An environmentally acceptable endpoint to assess immunotoxic potential of contaminated soils (1995)

Phagocytosis, a host-defense mechanism phylogenetically conserved throughout the animal kingdom, by earthworm (Lumbricus terrestris) coelomocytes has potential as a surrogate for vertebrates to be used as an environmentally acceptable endpoint to assess sublethal immunotoxic risks of contaminated soils to environmental (eg. higher wildlife) and public health. Coelomocytes can be exposed in vivo to complex contaminated parent soils by placing earthworms in situ at hazardous waste sites (HWS) or into soil samples and their dilutions with artificial soil (AS) in the laboratory, or in vitro to soil extracts and their fractionations. Here the authors report on phagocytosis by coelomocytes in earthworms exposed to pentachlorophenol (PCP) contaminated soils from a wood treatment HWS, PCP-spiked AS and PCP treated filter paper (FP). HWS soil was diluted to 25% with AS to a sublethal concentration (ca. 125 mg kg{sup {minus}1}) and earthworms exposed for 14d at 10 C under light conditions. AS was spiked at ca. 125 mg kg{sup {minus}1} PCP and earthworms were similarly exposed. Controls for both consisted of earthworms exposed to 100% AS. Earthworms were exposed to FP treated with a sublethal PCP concentration (15 {micro}g cm{sup {minus}2}) at 10 C under dark conditions for 96H. Controls were similarly exposed withoutmore » PCP. Phagocytosis by coelomocytes in earthworms exposed to HWS soil, spiked AS and treated FP was suppressed 37, 41 and 29%, respectively. Results are discussed in terms of PCP body burdens and exposure protocols.« less

Serum Oxidized Protein and Prostate Cancer Risk within the Prostate Cancer Prevention Trial (2010)

To evaluate the role of oxidative stress in prostate cancer risk, we analyzed serum levels of protein carbonyl groups in 1,808 prostate cancer cases and 1,805 controls, nested in the Prostate Cancer Prevention Trial, a randomized, placebo-controlled trial that found finasteride decreased prostate cancer risk. There were no significant differences in protein carbonyl levels in baseline samples between those later diagnosed with prostate cancer and those without at the end of study biopsy. Adjusted odds ratios and 95% confidence intervals (95% CI) for the 4th quartile of protein carbonyl level for the combined, placebo, and finasteride arms were 1.03 (95% CI, 0.85-1.24), 0.88 (95% CI, 0.69-1.12), and 1.27 (95% CI, 0.94-1.71), respectively. There were no significant associations between carbonyl level and risk when analyzing high-grade and low-grade disease separately, nor did finasteride affect protein oxidation levels. The results of this large nested case-control study do not support the hypothesis that oxidative stress, at least as measured by protein carbonyl level, plays a role in prostate cancer.
Effect of Egg Yolk Substances on the Metabolism of the Magnum in Vitro (1970)

Magnum slices from laying hens were incubated with buffer containing protein and lipid materials which passed through the vitelline membrane of yolks, obtained from ovary and from calcified eggs, to the surrounding buffer. Substances from ovarian yolk enhanced tissue respiration, protein secretion, alanine-glutamic transaminase activity, and inhibited incorporation of valine-14C into magnum proteins, 14C02 formation, and cystathionase activity. Substances from calcified egg yolk enhanced only protein secretion and inhibited tissue respiration, incorporation of radioactive valine into magnum proteins, and 14C02 formation. Aspartic-glutamic transaminase activity was not affected by experimental treatment. Individual values depend on the functional state of the oviduct. It was concluded that substances passing through the vitelline membrane of the yolk affect the metabolism and secretion of the magnum in vitro, suggesting that chemical stimuli may participate in the control of the functions of the oviduct in hen.
Self-Aligned, Extremely High Frequency III–V Metal-Oxide-Semiconductor Field-Effect Transistors on Rigid and Flexible Substrates (2012)

This paper reports the radio frequency (RF) performance of InAs nanomembrane transistors on both mechanically rigid and flexible substrates. We have employed a self-aligned device architecture by using a T-shaped gate structure to fabricate high performance InAs metal-oxide-semiconductor field-effect transistors (MOSFETs) with channel lengths down to 75 nm. RF measurements reveal that the InAs devices made on a silicon substrate exhibit a cutoff frequency (f(t)) of ∼165 GHz, which is one of the best results achieved in III-V MOSFETs on silicon. Similarly, the devices fabricated on a bendable polyimide substrate provide a f(t) of ∼105 GHz, representing the best performance achieved for transistors fabricated directly on mechanically flexible substrates. The results demonstrate the potential of III-V-on-insulator platform for extremely high-frequency (EHF) electronics on both conventional silicon and flexible substrates.

Effects of CO2 Introduction to the Reactive RF Sputtering Process for Micro-Crystalline Ge Thin Films (2010)

We proposed microcrystalline germanium (μc-Ge) as a material for infrared-sensitive photovoltaic cells. The μc-Ge usually shows no photo-sensitivity became of the strong p-type conduction due to negatively changed grain boundary defects. To suppress the p-type conduction, the compensation was attempted by oxygen doping. The oxygen doping was done by introducing carbon dioxide (CO2) and oxygen (O2) gases in the reactive sputtering process. We successfully obtained photo-sensitive μc-Ge with high crystallinity for the first time, due to the both CO2 and O2 introduction. The highest photo-sensitivity of 2.0 times was achieved by introducing 1.0×10-3 ccm of CO2 into the sputtering gas (Ar:10ccm, H2:100ccm). The crystallinity of μc-Ge is more affected by the introduction of CO2 than O2. The results show that the p-type defects in μc-Ge films can be compensated by the oxygen doping. The μc-Ge films with small amount of oxygen is a good candidate of narrow gap materials for photovoltaic cells and other devices with sensitivity of infrared light.
On the Relationship between Cholesteric and Nematic Mesophases (1973)

Abstract -The close relationship between nematic and cholesteric mesophases was realized in 1922 by Friedel and the conversion of nematics into cholesteric systems has been the subject of considerable research since that date. In the present work the relationship between the chirality of the induced cholesteric mesophases produced from the addition of simple chiral molecules, of known absolute configuration, to p-methoxybenzylidene-p'-n-butylaniline (MBBA) and butyl-p-p-(ethoxyphenoxycarbonyl)phenyl carbonate (BPC) and the chirality of the solute has been investigated. It was found that cholesteric mesophase chirality cannot be predicted from the chirality of the active solute alone even though the cholesteric mesophases produced by adding enantiomeric additives appear to be always enantiomeric. Predictions of the helical sense of the induced cholesteric mesophases require detailed energy calculations for the nematic-solute “complex” similar to those employed by Scheraga on helical macromolecules. The sign of the Cotton effect of the cholesteric liquid crystal induced circular dichroism (LCICD) band in MBBA and BPC was found to be the same as the sign of the reflective circular dichroism of the cholesteric pitch band. This result indicates that deviations in the optical activity versus wavelength plots for certain cholesteric mesophases from the theoretical predictions of deVries can be attributed to a strong contribution from LCICD. The overlapping of Cotton effects of the same sign may be used to explain the phenomenon that in mixtures of chiral compounds with nematics the optical rotation, at a wavelength smaller than the λ0, of the cholesteric pitch band, decreases as the quantity of the active component increases.
Heart wall velocity sensing using pulsed radar (2017)

A portable, hand-held radar module for hemodynamic heart monitoring using wideband radar is presented. The system consist of body coupled antennas, RF-amplifiers and core radar processor (adapted Novelda X2 chip) suitable for point-of-care use. Velocity measurements are compared with tissue doppler echocardiography for hemodynamic assessments. Both timing and amplitude of the velocity curves match, indicating the feasibility of using pulsed radar as a new modality for heart monitoring. With small size (60 mm × 30 mm × 50 mm) and low power consumption (< 1.5 W) the X2 SoC based pulsed radar system is suitable for portable hemodynamic heart monitoring. In the preliminary assessment consistency of the recorded data show low sensitivity to module placement indicating a robust system. Potentially the radar can be used by non-specialist for simple and frequent self-assessment.
Familial Clustering of Hepatitis B Infection (1973)

In a survey among 449 family contacts of blood donors from 197 households containing carriers of hepatitis B antigen, 6.7 per cent were antigen positive, as compared with 0.8 per cent in control households. The greatest prevalence of B antigen was among siblings (19.7 per cent) and other genetic family contacts (8 per cent). In spouses B antigen was less frequently detected (3.4 per cent). Hepatitis B antibody was detected three times more frequently in the study households than in control households. No differences in prevalence of hepatitis B antibody between specific relatives of antigen carriers were seen. Familial clustering does not appear to be correlated with the presence or absence of liver damage in the asymptomatic donor carrier. Neither venereal nor Maternal-Fetal transmission seems to be of primary importance in the spread of hepatitis B infections in these surveyed families. The evidence supports the hypothesis that hepatitis B virus can be transmitted nonparenterally. (N Engl J Med 289:1162–1166, 1973)
Continuous critic learning for robot control in physical human-robot interaction (2013)

In this paper, optimal impedance adaptation is investigated for interaction control in constrained motion. The external environment is modeled as a linear system with parameter matrices completely unknown and continuous critic learning is adopted for interaction control. The desired impedance is obtained which leads to an optimal realization of the trajectory tracking and force regulation. As no particular system information is required in the whole process, the proposed interaction control provides a feasible solution to a large number of applications. The validity of the proposed method is verified through simulation studies.
