Evaluation of hazard from intense sound with a mathematical model of the human ear (1996)

At its most basic, hazard to hearing is the result of energy arriving at the cochlea. However, the conductive path to the cochlea has many nonuniformities which profoundly shape the driving forces that actually reach it. The normal tuning of the ear as well as the azimuth of the source, an amplitude-dependent nonlinear middle ear, and time-varying middle ear muscle activity are in the conductive path and add to the complexity of interpreting the intracochlear events which culminate in hearing loss. To deal with this complexity, a mathematical model of the ear is being developed to predict hazard accurately. An earlier model for the cat ear [G. R. Price and J. T. Kalb, J. Acoust. Soc. Am. 90, 219–227 (1991)] has been adapted for the human ear and calculational procedures to allow for the effect of the azimuth of the source and middle ear muscle responses have been added. The model allows waveform input from the free field as well as at the ear canal entrance or ear drum position and calculates a hazard based on the stresses at the level of the basilar membrane. This number will be correlated with hearing losses measured from experiments with human ears.
Observation on laser-annealed silicon-on-insulator structures by cross-sectional transmission electron microscopy (1987)

Silicon-on-insulator (SOI) structures, fabricated by laser annealing, were observed with cross-sectional transmission electron microscopy. The film thickness was found to be almost uniform in SOI fabricated using a nonseeded Si3N4 antireflection film stripe technique, but some small mass transfer could be seen. Most of the crystal was of good quality, and almost no defects were observed, even in portions where stress was expected to be strongly exerted, such as at SOI/SiO2 interfaces or Si3N4 stripe edges. The defects which could be seen, however, were mostly those which had penetrated from the SOI/SiO2 interface to the SOI surface. Although the crystal quality was good, under relatively high laser power, dislocation loops were generated in the Si substrate. A grain boundary, generated from the deformed SOI/SiO2 interface, was also found. Furthermore, high-resolutional lattice image observations carried out for the lateral seeding epitaxy SOI revealed that the abruptness at the SOI/SiO2 interface was rougher than that at the SiO2/Si substrate interface.
Packaging for a wireless intraocular pressure sensor with a solder-filled microchannel antenna (2012)

A novel packaging method for an intraocular pressure (IOP) sensor is presented. The device, which will be implanted during cataract surgery, is 5.75 mm in radius and has to be folded to pass through an incision of 2–3 mm. A solder-filled microchannel approach is used for the antenna fabrication and packaging. A prototype of the device is tested at 1.5 GHz. A plot comparing the transmitted and received power is presented. It is shown that an ultra-low power radio frequency (RF) chip can be powered above its minimal requirement. Heat-assisted repair of fractured antennas is also studied in the presented fabrication method.
Mitochondrial morphology provides a mechanism for energy buffering at synapses (2019)

Mitochondria as the main energy suppliers of eukaryotic cells are highly dynamic organelles that fuse, divide and are transported along the cytoskeleton to ensure cellular energy homeostasis. While these processes are well established, substantial evidence indicates that the internal structure is also highly variable in dependence on metabolic conditions. However, a quantitative mechanistic understanding of how mitochondrial morphology affects energetic states is still elusive. To address this question, we here present an agent-based multiscale model that integrates three-dimensional morphologies from electron microscopy tomography with the molecular dynamics of the main ATP producing components. We apply our modeling approach to mitochondria at the synapse which is the largest energy consumer within the brain. Interestingly, comparing the spatiotemporal simulations with a corresponding space-independent approach, we find minor spatial effects when the system relaxes toward equilibrium but a qualitative difference in fluctuating environments. These results suggest that internal mitochondrial morphology is not only optimized for ATP production but also provides a mechanism for energy buffering and may represent a mechanism for cellular robustness.
Designing Effective Privacy Notices and Controls (2017)

Privacy notice and choice are essential aspects of privacy and data protection regulation worldwide. Yet, today's privacy notices and controls are surprisingly ineffective at informing users or allowing them to express choice. We analyze why existing privacy notices fail to inform users and tend to leave them helpless, and discuss principles for designing more effective privacy notices and controls.
Decomposition of generalized frequency response functions for nonlinear systems using symbolic computation (1996)

A symbolic manipulation procedure, which both computes and automatically decomposes the generalized frequency response functions of nonlinear rational, polynomial and integrodifferential equation models into a set of closed-form nth order transfer functions, is presented. The symbolic representation exposes the explicit relationship between the model parameters and the nonlinear transfer functions in the frequency domain and leads to important insights into the characterization of nonlinear systems. Examples for each model type are included to demonstrate the symbolic transfer function approach.
Intrinsic Optical Properties and Enhanced Plasmonic Response of Epitaxial Silver (2014)

The authors have realized that the calculation shown in the inset of Figure 2c plotted electric fi eld decay, while they had used intensity decay to defi ne propagation distance for the experimental data in the rest of the manuscript.The calculation plot is corrected here to refl ect intensity decay.In the inset of Figure 2c, the graph is replotted with semilog predictions.A plot of the predicted propagation distances using the JC data is also added.The predicted propagation distances at 632nm from all three predictions are now labelled.Some of the values quoted in the text that were based on this calculation were incorrect as a result of this.These values are also corrected here.As the graph in the inset of Figure 2c is also part of the table of contents image, the table of contents image is also corrected.
The 2007 Feinberg Lecture (2007)

The accumulated evidence suggests that neuroprotection failure in clinical trial is due to identifiable preclinical and clinical factors. Neuroprotection research should be pursued but with a very different and more rigorous approach.
Pagination versus Scrolling in Mobile Web Search (2016)

Vertical scrolling is the standard method of exploring search results pages. For touch-enabled mobile devices that are not equipped with a mouse or keyboard, we adopt other methods of controlling the viewport with the aim of investigating user interaction. From the intuition that people are used to reading books by turning pages horizontally, we conducted a user experiment to investigate the effects of horizontal and vertical control types (pagination versus scrolling) on a touch-enabled mobile phone. Our findings suggest that participants using pagination were more likely to find relevant documents, especially those over the fold; spent more time attending to relevant results; and were faster to click while spending less time on the search result pages overall. We also found that the main reason for the difference in search speed is the time taken for the scroll itself. We conclude that search engines need to provide different viewport controls to allow better search experiences on touch-enabled mobile devices.
Das Leistungsverweigerungsrecht des Arbeitnehmers an seiner Arbeitsleistung. (2009)

Sowohl in der Rechtsprechung als auch in der Literatur wird ein Leistungsverweigerungsrecht des Arbeitnehmers an seiner Arbeitsleistung einhellig anerkannt. Bedenken hinsichtlich der Anwendbarkeit der §§ 273 und 320 BGB, die in erster Linie auf die Fixschuldthese der herrschenden Meinung in Bezug auf die Arbeitsleistung zurückgehen, werden dabei vielfach mithilfe von Billigkeitserwägungen übergangen. Aus diesem Grund geht Florian Dehmel der Frage nach, ob sich die Anwendung der §§ 273 und 320 BGB auf die Arbeitsleistung dogmatisch überzeugend begründen lässt. Darauf aufbauend untersucht er, an welche Voraussetzungen die Ausübung des Leistungsverweigerungsrechts geknüpft ist und welche Rechtsfolgen bzw. praktischen Auswirkungen sich daraus ergeben. Schließlich wird überprüft, inwieweit die gefundenen Ergebnisse im Rahmen der Arbeitnehmerüberlassung Geltung beanspruchen.
The Acidity of Chloro-Substituted Benzenes: A Comparison of Gas Phase, Ab Initio, and Kinetic Data (2001)

The deprotonation energies of benzene, chlorobenzene, all di-, tri-, tetrachlorobenzenes, and pentachlorobenzene have been determined in the gas phase using a Fourier transform ion cyclotron resonance mass spectrometer. The values measured differ only slightly, though significantly, from the corresponding data for oligofluorobenzenes. The heavier halogen acidifies orthopositions slightly less and meta-positions slightly more than fluorine does. Moreover, the contributions of three or more chloro substituents are not perfectly additive. In fact the accumulation attenuates the contributions somewhat. Quantum chemical calculations at the MP2/6-311+G* level reproduce the gas-phase acidities fairly well, but reveal special effects when extended to experimentally not observable benzenides carrying the halogens at anion-remote positions. Competition experiments have been performed to assess the relative reactivity of nine oligochlorobenzenes towards sec-butyllithium in tetrahydrofuran at -100 degrees C. An almost exact linear correlation between logarithmic rates and gas-phase acidities has been found.
A Versatile Mixture Distribution and Its Application in Economic Dispatch with Multiple Wind Farms (2017)

An improved versatile distribution for wind power is proposed, with higher representation accuracy and more suitable applications in economic dispatch (ED) compared with Versatile distribution. Further, versatile mixture distribution (VMD) is proposed to represent all possible wind power distribution with customized arbitrary errors. Compared with Gaussian Mixture distribution (GMD), it has more flexible forms and can represent wind power more accurately. Its cumulative distribution function has analytical forms with higher computational efficiency. Then, real-time dynamic ED model and algorithm based on VMD with multiple wind farms (WFs) is proposed. Based on the VMD model, the probability distributions of wind power of each WF and the summation of all WFs are modeled. The ED model and algorithm solve the problem of the correlation of multiple renewable energy random variables with high computation efficiency for real-time ED. The results show that compared with GMD or unimodal distributions, VMD can represent wind power more accurately and can greatly simplify and speed up the ED model and algorithm. Compared with other methods for multiple renewable energy random variables, the proposed model and algorithm can improve economy significantly.
Targeting of the domain‐specific integral membrane protein PM52 to the periacrosomal plasma membrane during guinea pig spermiogenesis (1998)

The sperm plasma membrane is segregated into functionally, biochemically, and structurally distinct domains yet the protein sorting pathways and assembly mechanisms that assemble these domains during spermiogenesis are incompletely understood. We previously characterized two structurally related size-variant, integral membrane proteins of 52 kDa (PM52) and 35 kDa localized to the periacrosomal plasma membrane of guinea pig cauda epididymal spermatozoa (Westbrook-Case et al., 1994). In this study we used light and electron microscopic immunocytochemistry to define the expression pattern and sorting pathway that establishes the domain-specific distribution of PM52 during spermiogenesis. The PM52 is first expressed in acrosome-phase spermatids and it localizes exclusively to the cytoplasmic lobe. Immunoelectron microscopy revealed that both cytoplasmic vesicles and the plasma membrane of the cytoplasmic lobe labeled with anti-PM52. During early stages of expression, PM52 appeared to be absent from the head region, but significant PM52 accumulation over the spermatid head was noted in late acrosomal phase spermatids. Throughout spermiogenesis PM52 extended posteriorly to the annulus, which represents a barrier preventing PM52 diffusion into the posterior tail. Following the migration of the annulus to the midpiece-principal piece junction, PM52 began to disappear from the flagellar region and at the completion of spermiogenesis most of the PM52 was restricted to the acrosomal segment. Spermatids and epididymal sperm PM52 exhibited identical sizes by SDS-PAGE and immunoblotting, indicating that they are not proteolytically modified during epididymal maturation. The PM52 antibodies were also used to screen a guinea pig testis cDNA library, and sequence determination of full-length PM52 clones demonstrated identity of a sperm membrane protein recently termed “sperad” (Quill and Garbers, 1996). Membrane barriers and potential mechanisms establishing the domain-specific residence of PM52 are discussed. Mol. Reprod. Dev. 50:103–112, 1998. © 1998 Wiley-Liss, Inc.
Outer Ear Canal Infection with Rhabditis sp. Nematodes in a Human (2014)

ABSTRACT Here we report the first human case of an outer ear canal infection with a free-living nematode of the genus Rhabditis . Otomicroscopy revealed viable worms in the outer ear canal of a patient suffering from chronic otorrhea and hearing loss. The nematode was identified by microscopy and internal transcribed spacer (ITS)-PCR.
Arthroscopic treatment for limitation of motion of the elbow: the learning curve (2010)

This study demonstrated a learning curve in which a significant decrease in operative time was shown after an initial 15 patients. Motion and clinical score improvement were not satisfactory surrogate for learning curve and found to be closely related to preoperative range of motion. Qualification of the learning curve for arthroscopic treatment for limitation of motion of the elbow provides a guide for surgeons assuming the expected time line to become proficient in this technique.

The Role of Fibroblast Growth Factors in Tumor Growth (2009)

Biological processes that drive cell growth are exciting targets for cancer therapy. The fibroblast growth factor (FGF) signaling network plays a ubiquitous role in normal cell growth, survival, differentiation, and angiogenesis, but has also been implicated in tumor development. Elucidation of the roles and relationships within the diverse FGF family and of their links to tumor growth and progression will be critical in designing new drug therapies to target FGF receptor (FGFR) pathways. Recent studies have shown that FGF can act synergistically with vascular endothelial growth factor (VEGF) to amplify tumor angiogenesis, highlighting that targeting of both the FGF and VEGF pathways may be more efficient in suppressing tumor growth and angiogenesis than targeting either factor alone. In addition, through inducing tumor cell survival, FGF has the potential to overcome chemotherapy resistance highlighting that chemotherapy may be more effective when used in combination with FGF inhibitor therapy. Furthermore, FGFRs have variable activity in promoting angiogenesis, with the FGFR-1 subgroup being associated with tumor progression and the FGFR-2 subgroup being associated with either early tumor development or decreased tumor progression. This review highlights the growing knowledge of FGFs in tumor cell growth and survival, including an overview of FGF intracellular signaling pathways, the role of FGFs in angiogenesis, patterns of FGF and FGFR expression in various tumor types, and the role of FGFs in tumor progression.
Polymerized Complex Synthesis of Y2Ba4Cu7O14+d under One Atmospheric Oxygen Pressure. (1992)

High-purity ceramic sample of the superconducting Y2Ba4Cu7aO14.82 (247) phase has been prepared at 870°C by the polymerized complex method using neither high oxygen pressure nor the additive catalysts. The method is based on the formation of a polymer complex which is obtained through polyesterification between metal citrate complexes and ethylene glycol. Apart from not requiring high oxygen pressure, the present preparation technique offers more convenient fabrication of highly pure 247 compound compared with other wet chemical routes since it eliminates many steps such as aging and pH control. X-ray diffraction and Raman scattering analyses have shown that the material is virtually of single-phase without any indication of secondary phases. Zero resistance has been achieved at 88.0K with a transition width narrower than 4 K. Complex magnetic susceptibility measurements have confirmed the presence of a single bulk superconducting 247 phase with Tc(onset)=93.0 K and ΔTc(10-90%)=4.0 K.
Distinct virulence of Rift Valley fever phlebovirus strains from different genetic lineages in a mouse model (2017)

Rift Valley fever phlebovirus (RVFV) causes high rates of abortions and fetal malformations in ruminants, and hemorrhagic fever, encephalitis, or blindness in humans. Viral transmission occurs via mosquito vectors in endemic areas, which necessitates regular vaccination of susceptible livestock animals to prevent the RVF outbreaks. Although ZH501 strain has been used as a challenge strain for past vaccine efficacy studies, further characterization of other RVFV strains is important to optimize ruminant and nonhuman primate RVFV challenge models. This study aimed to characterize the virulence of wild-type RVFV strains belonging to different genetic lineages in outbred CD1 mice. Mice were intraperitoneally infected with 1x103 PFU of wild-type ZH501, Kenya 9800523, Kenya 90058, Saudi Arabia 200010911, OS1, OS7, SA75, Entebbe, or SA51 strains. Among them, mice infected with SA51, Entebbe, or OS7 strain showed rapid dissemination of virus in livers and peracute necrotic hepatitis at 2-3 dpi. Recombinant SA51 (rSA51) and Zinga (rZinga) strains were recovered by reverse genetics, and their virulence was also tested in CD1 mice. The rSA51 strain reproduced peracute RVF disease in mice, whereas the rZinga strain showed a similar virulence with that of rZH501 strain. This study showed that RVFV strains in different genetic lineages display distinct virulence in outbred mice. Importantly, since wild-type RVFV strains contain defective-interfering RNA or various genetic subpopulations during passage from original viral isolations, recombinant RVFV strains generated by reverse genetics will be better suitable for reproducible challenge studies for vaccine development as well as pathological studies.

Journal of Cataract & Refractive Surgery: May 1986 - Volume 12 - Issue 3 - p 308-312 doi: 10.1016/S0886-3350(86)80021-9
Condition Assessment of Aged Ester-Based Nanofluid Through Physicochemical and Spectroscopic Measurement (2019)

Vegetable oils (VOs) are based on natural ester oil that is considered as an alternative to mineral oil for transformer applications. The dispersion of nanofillers into the VO is expected to improve the physicochemical and electrical performances. Surface-modified insulating nanoparticle is dispersed into the VO to prepare the VO-based nanofluid (NF). An open-beaker oxidative aging study is carried out at 115 °C for VO and NF at three distinct aging durations such as 100, 300, and 500 h. Alterations in the molecular level of aged VO and NF are studied through the various spectroscopic and physicochemical analyses such as nuclear magnetic resonance, Fourier transform infrared, UV-vis absorbance, fluorescence, color, acid number, interfacial tension, and flash point. The fluorescence-based analysis is carried out for VO and NF at fresh and aged condition to monitor the comparative aging degradation. Oxidative aging of VO and NF results in the formation of flammable and harmful gases, which are analyzed using dissolved gas analysis technique. A comparative analysis of the electrical properties such as ac breakdown voltage, dielectric constant, and dielectric dissipation factor for fresh and aged sample of VO and NF is studied.
