SPATIAL TRACK TRANSITION EFFECTS FOR HEADPHONE LISTENING (2007)

In this paper we study the use of different spatial processing techniques to create audio effects for forced transitions between music tracks in headphone listening. The audio effect encompasses a movement of the initially playing track to the side of the listener while the next track to be played moves into a central position simultaneously. We compare seven different methods for creating this effect in a listening test where the task of the user is to characterize the span of the spatial movement of audio play list items around the listener’s head. The methods used range from amplitude panning up to full Head Related Transfer Function (HRTF) rendering. It is found that a computationally efficient method using time-varying interaural time differences is equally effective in
Organic Polymer Thin-Film Transistor Photosensors (2004)

We present our study of the effects of monochromatic illumination on the electrical performance of organic polymer thin-film transistors (OP-TFTs) and the use of these devices as photosensors. In the case of monochromatic illumination that is strongly absorbed by the polymer, the drain current of a device biased in the OFF-state is significantly increased and the threshold voltage is reduced. Light that is not strongly absorbed by the polymer has little effect on the electrical performance of the OP-TFTs. We explain these effects in terms of the photogeneration of excitons in the polymer channel region of the device. The density of excitons generated in the polymer depends on the energy of the incident photons, as well as on the irradiance level of the incident illumination. The photogenerated excitons subsequently dissociate into electrons and holes. The electrons can be trapped by positively charged states, thereby reducing the threshold voltage, while the photogenerated holes contribute to the excess photocurrent measured at the drain. To demonstrate the possible use of OP-TFTs as photosensors, we also present the responsivity, photosensitivity (signal-to-noise ratio), external quantum efficiency, noise-equivalent power, and specific detectivity of these devices. The dependence of these parameters on the incident photon energy and irradiance level is described.

Treatment Dose-Response in Amblyopia Therapy: The Monitored Occlusion Treatment of Amblyopia Study (MOTAS) (2004)

Continuous objective monitoring of the amount of patching therapy received has provided insight into the dose-response relationship of occlusion therapy for amblyopia. Patching is most effective within the first few weeks of treatment, even for those in receipt of a relatively small dose. Further studies are needed to elucidate the neural basis for the dose-response functions.
A new endogenous retroviral sequence is expressed in skin of patients with psoriasis (2005)

In psoriatic lesions, HERV sequences of the W, K and E families are expressed and a new variant of the ERV-9/HERV-W family has been characterized. The possible role of HERV-related sequences in the pathogenesis of psoriasis is under investigation.
Changing Sources of Care for HIV Infection in California (2000)

A telephone survey was conducted of random samples of primary care physicians in Los Angeles County and in the 26 rural counties of California to assess changes in medical practices that may have occurred with the development of new pharmacological agents and recent changes in the management of infection with the HIV. Seventy-two to seventy-three percent of the physicians selected participated in the survey in both areas. The results indicate a reduction by almost two thirds of the number of primary care physicians who plan to continue to provide care to HIV-infected patients, both in Los Angeles County and the nonmetropolitan counties of California. Although some were no longer caring for HIV patients because of deaths or patient relocation, the overwhelming majority had referred their patients to infectious disease specialists and HIV clinics because of the growing complexity of the management of these patients.

Reaction of oxygen atoms with carbonyl compounds. Part 2.—Acetaldehyde (1974)

The reaction of excess atomic oxygen with acetaldehyde in a discharge-flow system has been studied at temperatures between 195 and 573 K. Kinetic studies and product analyses establish the mechanism to be O + CH3CHO → CH3CO + OH (1), O + OH → O2+ H (2), O + CH3CO → CH3+ CO2(9), O + CH3→ H2CO + H (7) followed by reaction between oxygen atoms and formaldehyde. At 573 K, the reduction of the carbon dioxide yield on increasing the pressure from 1 to 10 Torr is caused by unimolecular decomposition of acetyl radicals. At 300 K, k1=(2.88 ± 0.3)× 1011 cm3 mol–1 s–1.

SOLUTION TECHNIQUES IN FLUORESCENT X-RAY SPECTROGRAPHY (1958)

The applications and limitations of solution techniques as a general method of fluorescent x-ray spectrographic analysis were determined. Systematic errors due to variations in particle size, surface preparation, and sample inhomogeneity are eliminated by the use of solutions. The range of applicability of fluorescent xray spectrography is increased by samples in the form of wire, filings, turnings, etc., which can be analyzed as solutions, and samples submitted as solutions which can be analyzed as received. The lower limit of detectability varies from 0.14 gram per liter for sulfur to 0.0015 gram per liter for strontium. Most elements have limits of detectability between 0.02 and 0.002 gram per liter.

Age-dependent presence of antibodies in rat dams, capable of conferring protection against group B Streptococcus infection in neonates (2001)

A rat model was used to investigate maternal age-dependent resistance on group B Streptococcus (GBS)-induced mortality of the offspring.Offspring from young (first time) or older (repeat litters) dams were challenged with GBS.There was an approximate log difference in the dose of GBS required to cause identical levels of mortality in the two groups.The sera of the dams from both groups were analysed by whole-cell ELISA, and it was demonstrated that sera from the older dams possessed circulating IgG cross-reactive to GBS.Since IgG is transplacentally transferred, we conclude that this is the method of observed protection.
A motion compensated fiber optic confocal microscope based on common-path optical coherent tomography distance sensor (2011)

A motion compensated fiber optic confocal microscope system is demonstrated using a combination of a Fourier domain common-path optical coherence tomography (CP-OCT) distance sensor and a high-speed linear motor. The confocal microscope is based on 460 micron diameter fiber bundle terminated with a gradient index (GRIN) lens. Using the peak detection of a 1-D A-scan data of CP-OCT, the distance deviation from the focal plane could be monitored in real-time. When the distance deviation surpasses a certain threshold, the linear motor drives the confocal microscope probe at a speed related to the change in the deviation to maintain the deviation within a predetermined limit. The motion compensation was achieved for a confocal microscope imaging rate of 1Hz with an average distance error of 4 microns.

Geosmin and 2-Methylisoborneol from Cyanobacteria in Three Water Supply Systems (1982)

Three Oscillatoria strains and one Anabaena species were isolated from three different water supply systems in California that experienced earthy-musty taste and odor problems in their drinking water. Unialgal cultures, free of actinomycetes, were purged using the Grob closed-loop stripping analysis method, and the resulting methylene chloride extracts were analyzed on a gas chromatograph/mass spectrometer. Geosmin was produced by Oscillatoria simplicissima and Anabaena scheremetievi, and 2-methylisoborneol was produced by O. curviceps and O. tenuis. These compounds are the two major causes of earthy-musty tastes and odors in water. In three instances, the major odorant found in culture was previously identified in the water or sediment sample from which the respective organism was isolated. O. curviceps was implicated in a taste and odor episode involving 2-methylisoborneol in a major reservoir. Geosmin and 2-methylisoborneol were easily detected with culture samples of only 4 to 25 ml.
Biodegradation of poly(vinyl alcohol) with different molecular weights and degree of hydrolysis (2000)

The biodegradability of poly(vinyl alcohol) (PVA) was investigated under different conditions by respirometric determinations, iodometric analysis, and molecular weight evaluation. Microbial inocula derived from the sewage sludge of municipal and paper mill wastewater treatment plants were used. A rather active PVA-degrading bacterial mixed culture was obtained from the paper mill sewage sludge. Significant biodegradation levels within quite short incubation times were obtained in liquid cultures in the presence of acclimated microbial populations. The influence of some polymer properties such as molecular weight and degree of hydrolysis on the biodegradation rate and extent was investigated in the presence of either the acclimated mixed bacterial culture or its sterile filtrate. Kinetic data relevant to PVA mineralization and to the variation of PVA concentration, molecular weight, and molecular weight distribution revealed a moderate effect of the degree of hydrolysis. The molecular weight appeared to be not a limiting factor of microbial attack. Comparison of the degradation process in the presence of either bacterial cells or their culture filtrate highlighted the ability of some microbial strains to utilize polymer chains having 5–10 kD molecular weight. This result suggests the occurrence of two PVA degradation mechanisms: a random-type attack and a terminal unzipping depolymerization process of polymer chains.

Low-level laser irradiation inhibits abdominal aortic aneurysm progression in apolipoprotein E-deficient mice (2009)

These in vivo studies, together with previous in vitro studies from this laboratory, appear to provide strong evidence in support of a role for LLLI in the attenuation of aneurysm progression. Further studies in large animals would appear to be the next step towards testing the applicability of this technology to the human interventional setting.
Robot Controlled Osteotomy in Craniofacial Surgery (1999)

Interventions in craniofacial surgery are a great challenge to the operating surgeon, as high precision and long practise are required to perform optimal bone repositionings and to achieve and aesthetic and satisfactory result. Although methods and devices for the preoperative planning of bone repositionings do already exist, the accurate intraoperative transposition of a surgical plan still is a problem. For this solution a joint procject to develop a computer aided method using a surgical robot to control the surgeon&apos;s movements while cutting bone was conceived by the surgeons of the Clinic of Maxillofacial Surgery of the University of Heidelberg and the engineers at the Intitute of Process Control and Robotics (IPR), whichwe present in this paper.
Creating Robust Activity Maps Using Wireless Sensor Network in a Smart Home (2007)

This paper presents a practical application called "activity map" to serve as guidance to show ambient intelligence-related contextual information gathered from both humans and their surrounding environments. The activity map utilizes results inferred from a location-aware activity recognition approach to statistically show a resident's possibly interleaved activities along with corresponding location-related contexts. With observations from a variety of multi-modal and non-intrusive wireless sensors, the approach utilizes a Bayesian network fusion engine with inputs from a set of the most informative features extracted from the sensors and applies joint inference to improve the accuracy and consistency of activity and location estimates. Additionally, each feature has to reckon its corresponding reliability factor to control its contribution in case of possible device failure, therefore making the system more tolerant to inevitable disturbance commonly encountered in a cluttered home environment. This mechanism can cope with some inherent sensor limitations and noise interference, thus improving overall robustness and performance. All experiments were conducted in an instrumented living lab and their results demonstrate the effectiveness of the system.
Modification of Porous Alumina Membranes Using Al<sub>2</sub>O<sub>3</sub> Atomic Layer Controlled Deposition (1997)

Al2O3 films were deposited with atomic layer control inside the pores of Anodisc alumina membranes. To achieve this controlled deposition on a high aspect ratio structure, a binary reaction for Al2O3 chemical vapor deposition (2Al(CH3)3 + 3H2O → Al2O3 + 6CH4) was separated into two half-reactions: (A) AlOH* + Al(CH3)3 → Al-O-Al(CH3)2* + CH4 and (B) AlCH3* + H2O → AlOH* + CH4, where the asterisks designate the surface species. The trimethylaluminum [Al(CH3)3] (TMA) and H2O reactants were employed alternately in an ABAB... binary reaction sequence to deposit the Al2O3 film. Because each half-reaction is self-limiting, atomic layer controlled Al2O3 deposition was achieved on the surface of the high aspect ratio pores. To determine the necessary reaction conditions, surface species during each half-reaction were periodically monitored using in situ transmission FTIR spectroscopy. Ex situ gas flux and permporometry measurements were also performed to determine the effect of the binary reaction sequence on the pore diameter. Gas flux measurements for H2 and N2 were consistent with a progressive pore size reduction versus the number of AB reaction cycles. The permporometry measurements showed that the original pore diameter of ∼220 Å was reduced to ∼140 Å after 120 AB reaction cycles.
[Studies on the separation and determination of natural phenolic acids by reversed-phase high performance liquid chromatography]. (2002)

A new method using gradient elution of reversed-phase high performance liquid chromatography was set up for the separation and determination of 12 natural phenolic acids simultaneously. The separation conditions were studied with a Zorbax ODS (5 microns) column, and optimized conditions were suggested with the mobile phase gradient elution of CH3CN-H2O (with 0.5% HAc) (5:95-->35:65, V/V, in 40 min) at room temperature, flow rate at 1.0 mL/min and detection wavelength at 280 nm. And the effects of acidity on separations and the relationships between the phenolic acids structures and their retention behaviors were discussed. Qualitative and quantitative analysis of the 12 compounds were performed. The regression equation, correlation coefficient, linear range, detection limit and relative standard deviation (RSD) of each compound were obtained under the optimized conditions. The correlation coefficients of the 12 compounds were between 0.9980 and 0.9999. The detection limits ranged from 0.96 ng to 4.10 ng and RSDs were < or = 2.64%. These results demonstrate that the optimized determination method obtained is successful for the separation and determination of the 12 phenolic acids analysed.
Macrosegregation Quality Criteria and Mechanical Soft Reduction for Central Quality Problems in Continuous Casting of Steel (2014)

In order to study the central quality of continuously cast tool steel slabs, the simple model has been developed to simulate the macrosegregation quality criteria. The model calculates different quality criteria such as average macro-segregation level criterion “ASL”, its fluctuation level “FSL” and its segregation quality number “SQN”. These criteria are calculated based on the previous measurements of carbon and sulfur concentrations distributions in final region of spray zones and centerline area of lower and upper slab sides. The effect of mechanical soft reduction Technique “MSR” on the slab centerline quality is examined and analyzed. The model results show that MSR affects the quality of centerline areas significantly by different ways based on the casting speed. The experimental and theoretical results clarify that the qualities of different slab sides are different for all collected samples. The model results show also that the accuracy of the macro-segregation quality criteria increases quantitatively with increasing the number of analyzed segregated elements. Therefore, the macrosegregation quality criteria and their distributions can be considered as the most simple and vital tool to evaluate the various slab qualities. Finally, the mechanism of centerline segregation formation with mechanical soft reduction is discussed in this study.
Cytochrome c at charged interfaces. 1. Conformational and redox equilibria at the electrode/electrolyte interface probed by surface-enhanced resonance Raman spectroscopy (1989)

The structure and the electron-transfer properties of cytochrome c (cyt c) absorbed on a silver electrode were analyzed by surface-enhanced resonance Raman spectroscopy. It was found that the absorbed cyt c exists in various conformational states depending on the electrode potential. In state I the native structure of the heme protein is fully preserved and the redox potential (+0.02 V vs saturated calomel electrode) is close to the value for cyt c in solution. In state II the heme iron exists in a mixture of five-coordinated high-spin and six-coordinated low-spin configurations. It had been shown that these configurations form a thermal equilibrium [Hildebrandt, P., & Stockburger, M. (1986) J. Phys. Chem. 90,6017]. It is demonstrated that these equilibria strongly depend on the charge distribution within the electrical double layer of the silver electrode/electrolyte interface, indicating that the changes in the coordination shell are induced by electrostatic interactions. The structural alterations in state II are apparently restricted to the heme crevice, which assumes an open conformation compared to the close structure in state I. This leads to a strong decrease of the redox potentials, which were determined to be -0.31 and -0.41 V for the five-coordinated high-spin and six-coordinated low-spin configurations, respectively. On the other hand, gross distortions of the protein structure can be excluded since the reversible proton-induced conformational change of cyt c as found in solution at low pH also takes place in state II of the absorbed cyt c. The linkage of cyt c molecules to the surface is mediated by charged amino acid groups, and it depends on the potential which groups are thermodynamically favored to form such a molecular binding site. The conformational states I and II, which are in potential-dependent equilibrium, therefore refer to two different molecular binding sites. At potentials below zero charge (less than approximately -0.6 V) a rapid denaturation of the absorbed cyt c is noted, which is reflected by drastic and irreversible changes in the surface-enhanced resonance Raman spectrum. Our results are discussed on the background of previous electrochemical studies of cyt c at electrodes.
