The Varieties of Auditory Neuropathy (2000)

Auditory neuropathy (AN) was initially described as impairment of auditory neural function, with preserved cochlear hair cell function. In this report, 67 patients with audiological and neurophysiological criteria for hearing loss due to auditory neuropathy are described. Reviewing this large body of patients, AN appears to consist of a number of varieties, with different etiologies and sites affected. All varieties share a relatively spared receptor function, and an impaired neural response, with diminished ability to follow fast temporal changes in the stimulus, but different varieties in this general scheme can be distinguished. Analyses of the clinical features indicate that auditory neuropathies vary in several measures including age of onset, presence of peripheral neuropathy, etiology, and behavioral and physiological measures of auditory function. The sites affected along the peripheral auditory pathway may include dysfunction of the outer hair cells, the synapse between hair cell and auditory nerve, and the auditory nerve fibers, with myelin as well as axonal impairments contributing to the disorder.

Sub-pixel registration and estimation of local shifts directly in the fourier domain (2005)

In this paper, we propose a new approach to sub-pixel registration, and the estimation of local shifts between a pair of images, directly in the Fourier domain. For this purpose, we establish the exact relationship between the continuous and the discrete Fourier phase of two shifted images or their subregions. In particular, we show that the discrete phase difference of two shifted images is a 2-dimensional sawtooth signal, with the exact shifts determined to sub-pixel accuracy by the number of periods of the phase difference along each frequency axis. The sub-pixel portions of the shifts are determined by the non-integer fraction of a period of the phase difference.
Molecular Structure and Dispersion-Adsorption Mechanisms of Comb-Type Superplasticizers Used in Japan (2003)

This paper summarizes the relation between the molecular structure and the dispersion-adsorption mechanisms of 3 types of comb-type superplasticizers used in Japan. The action mechanisms of comb-type superplasticizers and the compatibility of cements and superplasticizers are influenced by the molecular structure of polymers such as copolymer components and the grafted chain length of poly (ethylene-oxide) (PEO). Many reports regarding concrete research have investigated the influence of comb-type superplasticizers on the fluidity of concrete and the production of selfcompacting concrete. However, many have not considered the effect of the molecular structures of comb-type superplasticizers. This paper should be useful for engineers and researches studying the action of comb-type superplasticizers in the production of concrete with comb-type superplasticizers, and for understanding any new properties of such concrete.
Fate of isoxathion (O,O-diethyl O-(5-phenyl-3-isoxazolyl)-phosphorothioate) in soils. (1975)

The persistence and degradation of isoxathion 14C-labeled at the 5-position of the isoxazole ring were studied in three soil types under laboratory conditions. Persistence was influenced by soil type and moisture content; approx. half life at 30 ppmw dose level varied from 15 to 40 days in nonflooded models. In a flooded model isoxathion disappeared much faster. Isoxathion underwent biodegradation to a number of products with concomitant release of 14CO2. 3-Hydroxy-5-phenylisoxazole, 5-phenyl-4-oxazolin-2-one, benzoylacetamide and benzoic acid were the unequivocally identified metabolites; oxon derivative of isoxathion, 3-methoxy-5-phenylisoxazole, 2-methyl-5-phenyl-4-isoxazolin-3-one, 2-acetyl-5-phenyl-4-isoxazolin-3-one, 2, 5-diphenylpyrazine and acetophenone were tentatively identified as the minor products. None of these major products was persistent in soils. 3-Hydroxy-5-phenylisoxazole, the initial metabolite or hydrolyzate of isoxathion, was adsorbed to soil to a much greater extent than isoxathion, which explains the rapid disappearance of its fungicidal activity in soil.
Simultaneous interfacial misfit array formation and antiphase domain suppression on miscut silicon substrate (2008)

The authors describe simultaneous interfacial misfit (IMF) array formation along with antiphase domain (APD) suppression in highly mismatched (Δa0/a0=13%) AlSb grown on a 5° miscut Si (001) substrate. Strain energy from the AlSb/Si heterojunction is accommodated by a self-assembled two-dimensional array of pure 90° dislocations confined to the interface. The 13% lattice mismatch establishes the AlSb/Si IMF period of ∼3.46 nm. This IMF spacing is well matched to the step length of the 5° miscut Si (001) substrate. Furthermore, the miscut substrate geometry suppresses APD formation due to the double step height. The resulting bulk material has both very low defect density (∼7×105/cm2) and very low APD density (∼103/cm2) confirmed by transmission electron microscope images. This material is expected to be desirable for electronic III-V devices on Si substrates.
Characterization and mechanism studies of dielectric barrier discharges generated at atmospheric pressure (2010)

A dielectric barrier discharge (DBD) device operated at ambient air with an ac power supply was designed and examined. The discharge power and active current of DBD were characterized. Experimental results show that the discharge power does not proportionally increase all along with voltage. Through in-depth analysis of typical waveforms of instantaneous applied voltage and discharge current, and images of microdischarges in the gas gap, it is inferred that considerable reduction in charges transferred through discharge channels is most likely due to recombination and attachment to electronegative molecules, nonuniform highly distorted electric fields, and repulse of more homogeneous electric charges.
Tunnel Diode Arrays for Information Processing and Storage (1971)

The multimode oscillator properties of two-dimensional arrays of tunnel diode elements are analyzed in the quasi-harmonic approximation with the assumption of no resonant interaction between the normal modes in order to determine the capacity of an array for information storage. Experimental results for a 4 × 4 array of semiconductor tunnel diodes are discussed, and suggestions for possible future information processing applications are presented.
Power electronics for aircraft application (1999)

Advancements in power electronics technologies have been used widely in the aerospace industry. Lucas Aerospace provides a variable frequency voltage for most of the internal power system in the aircraft, however some components may be required to be operated with DC or fixed frequency voltage. An aircraft power conditioning system is shown. It consists of a variable frequency generator. A part of the output of the generator is rectified to provide low voltage (usually 28 V) and high voltage DC. The high voltage is inverted again to give 115 V RMS, 400 Hz constant frequency. This paper presents a research project which is aimed at producing a high power variable frequency to constant frequency converter. Simulation results are presented and compared with the international standard specifications.
Determination of Digestibility, Tissue Deposition, and Metabolism of the Omega-3 Fatty Acid Content of Krill Protein Concentrate in Growing Rats (2010)

Krill protein concentrate (KPC) consists of high-quality protein (77.7% dry basis) and lipids (8.1% dry basis) that are rich (27% of total fatty acids) in omega-3 polyunsaturated fatty acids (omega-3 PUFAs). The objective of the study was to determine digestibility, tissue deposition, metabolism, and tissue oxidative stability of the omega-3 PUFAs provided by KPC. Young female Sprague-Dawley rats (n = 10/group) were fed ad libitum isocaloric diets for 4 weeks with either 10% freeze-dried KPC or 10% casein. The casein diet contained 5.3% added corn oil (CO), whereas the KPC contained 5.3% total lipids from 0.9% krill oil (KO) provided by KPC and 4.4% added corn oil (KO + CO). Fatty acid compositions of various tissues were analyzed by gas chromatography. Lipid peroxidation was determined by thiobarbituric acid reactive substances (TBARS). Total antioxidant capacity and urinary eicosanoid metabolites were determined by enzyme immunoassay. The omega-3 PUFAs provided in KO from KPC increased (P = 0.003) docosahexaenoic acid (DHA) concentration in the brain. DHA and eicosapentaenoic acid (EPA) content in fat pads and liver were increased (P < 0.01), whereas the omega-6 PUFA, arachidonic acid (AA), was decreased (P < 0.01) in rats fed the KPC diet containing the KO + CO mixture compared to rats fed the casein diet containing pure CO. Feeding the KPC diet decreased pro-inflammatory 2-series prostaglandin and thromboxane metabolites. There was no significant difference in TBARS or total antioxidant capacity in the tissues of rats fed the different diets. On the basis of the study results, the low amount of omega-3 PUFAs provided by the KO content of KPC provides beneficial effects of increasing tissue EPA and DHA deposition and reduced AA-derived 2-series eicosanoid metabolites without increasing lipid peroxidation. Therefore, consumption of KPC has the potential to provide a healthy and sustainable source of omega-3 PUFAs.

K-Medoids Clustering Using Partitioning Around Medoids for Performing Face Recognition (2014)

Face recognition is one of the most unobtrusive biometric techniques that can be used for access control as well as surveillance purposes. Various methods for implementing face recognition have been proposed with varying degrees of performance in different scenarios. The most common issue with effective facial biometric systems is high susceptibility of variations in the face owing to different factors like changes in pose, varying illumination, different expression, presence of outliers, noise etc. This paper explores a novel technique for face recognition by performing classification of the face images using unsupervised learning approach through K-Medoids clustering. Partitioning Around Medoids algorithm (PAM) has been used for performing K-Medoids clustering of the data. The results are suggestive of increased robustness to noise and outliers in comparison to other clustering methods. Therefore the technique can also be used to increase the overall robustness of a face recognition system and thereby increase its invariance and make it a reliably usable biometric modality.

Growth of optical superlattice LiNbO3 with different modulating periods and its applications in second-harmonic generation (1996)

Optical superlattice LiNbO3 crystals with a modulation period number over 200 and a modulation period from 2.0 to over 15.0 μm were grown by the Czochralski method in a carefully designed asymmetric temperature field system. Measurements of the frequency doubling efficiency for generating light from blue to green were performed. The largest efficiency obtained was 24.0% for frequency doubling of a picosecond 980 nm fundamental light. The angle tuning tolerance of a LiNbO3 optical superlattice was measured to be over 10° of the incidence angle.

A novel high performance SiGe channel heterostructure dynamic threshold pMOSFET (HDTMOS) (2001)

In this letter, we propose a novel SiGe channel heterostructure dynamic threshold metal oxide semiconductor (DTMOS) and demonstrate its superiority over conventional Si-DTMOS. The introduction of a SiGe layer for the channel is very effective for reducing the threshold voltage in spite of keeping impurity doping level at the body region. Therefore, a low threshold voltage and a large body effect factor can be achieved simultaneously. The SiGe HDTMOS with highly doped body exhibits two times higher transconductance, 1.4 times higher saturation current, and better short channel immunity than that of the control Si-DTMOS with lightly doped body of which threshold voltage is nearly the same.
Variability of the pigment apparatus in Cyanophyta depending on carbon nutrition conditions (2000)

Variability of composition, pigment content (chlorophyll a, carotenoids, phycobiliproteins) and biomass accumulation have been studied in two strains of Nostoc punctiforme (Kütz.) Hariot (strain 38 and 39) and N. muscorum Ag. (strain 81) under conditions of different types of carbon nutrition. Infraspecific and interspecific variability of chromatic characteristics is found under heterotrophic (in light and darkness) conditions of Cyanophyta cultivation. Under the test conditions interspecific variability of pigments essentially prevailed over the infraspecific. All studied species of the genus Nostoc Vauch. differ in degree of photo- and heterotrophy. It has been established that variations in carbon nutrition conditions result both in destructive and in adaptive changes in the pigment content in the representatives of this genus. Physiological adaptation of the pigment apparatus of Cyanophyta on the photoheterotrophic type of nutrition with diurone is aimed at compensatory strengthening of the photosystem II activity, which is confirmed by intensification of synthesis in phycobilin pigments.
Cellulose Nanocrystals for Thermoplastic Reinforcement: Effect of Filler Surface Chemistry on Composite Properties (2006)

Many properties of a composite material depend on the nature of the interface between the different components. To study the effect of filler surface chemistry, composites of cellulose acetate butyrate and both native and surface-trimethylsilylated cellulose nanocrystals from bacterial cellulose were investigated by differential scanning calorimetry and dynamic mechanical analysis. Both fillers affected the crystallization of the matrix during solution casting, caused a decrease in heat capacity in the composites, an increase in storage and loss modulus, and a decrease in damping. The increase in composite stiffness was larger for the native fillers. Yet, increases in matrix melting temperatures and recrystallization upon heating as well as a larger decrease in damping indicated better filler-matrix compatibility for the silylated crystals.
Role of nonhemoglobin heme accumulation in the terminal differentiation of Friend erythroleukemia cells. (1981)

The differentiation of murine erythroleukemia cells (T3C12 Friend cells) on treatment with dimethyl sulfoxide (DMSO) has been correlated with an early and extended overproduction of heme. The cessation of cell replication and the development of nuclear condensation, changes which are associated with the terminal differentiation of these cells, occur when the level of heme rises 0.1 nmol/10(6) cells over that amount which can be complexed by globin protein. A significant fraction of the excess heme is localized in the nuclei of the DMSO-treated cells. The addition of exogenous hemin facilitates the onset of terminal differentiation in the DMSO-treated T3C12 cells, whereas only the induction of globin gene expression is observed in the absence of DMSO. To study the role of heme in erythroid differentiation, a Friend cell variant (R10) has been isolated whose synthesis and accumulation of heme in response to DMSO is deficient. This variant grows logarithmically in the presence of DMSO and fails to terminally differentiate. When exogenous hemin is added, the DMSO-treated R10 cells stop replicating. In the absence of DMSO, however, hemin-treated R10 cells continue to grow and express their globin genes without exhibiting other signs of terminal differentiation. The combined results support the conclusion that both the DMSO treatment and the accumulation of excess heme are required to bring about the terminal differentiation of Friend erythroleukemia cells. Preliminary evidence is presented which suggests that in addition to the induction of heme and globin synthesis, DMSO also induces a heme activation process which is required for differentiation. The possible relationship of this process to the terminal differentiation of erythroid cells is discussed.

Study on structure and magnetic entropy changes of Ce2-xPrxFe16.5Co0.5 alloys (2006)

A series of Ce2-xPrxFe16.5Co0.5 alloys were preparedby arc melting under purified argon atmosphere. The structure and magnetic entropy changes in Ce2-xPrxFe16.5Co0.5 alloys were investigated by means of X-ray diffraction pattern and MPMS XL-7 magnetometer. The experimental results show that the crystal structure of Ce2-xPrxFe16.5Co0.5 alloys keeps in TH2Zn17-type rhombohedral, and the Curie temperature of Ce2-xPrxFe16.5Co0.5 alloys can be shifted to room temperature around by a composition adjustment. The magnetic entropy changes (-ΔSM) in Ce2-xPrxFe16.5Co0.5 alloys are relatively large, and a platform of magnetic entropy changes appearsnear the temperature TC. Ce2-xPrxFe16.5Co0.5 alloys are the potential working media for magnetic refrigeration with their stable chemical properties and especially low price.
RhoA/Rho-Kinase as a Therapeutic Target in Asthma (2008)

Rho-kinase is an effector molecule of RhoA, a monomeric GTP-binding protein, and causes Ca(2+) sensitization via inactivation of myosin phosphatase. The major physiological functions of Rho-kinase include contraction, migration, and proliferation in cells. These actions are thought to be related to the pathophysiological features of asthma, i.e., airflow limitation, airway hyperresponsiveness, beta-adrenergic desensitization, eosinophil recruitment and airway remodeling. Here, the roles of RhoA/Rho-kinase in the pathophysiology and treatment of asthma were investigated. In airway smooth muscle, pre-exposure to chemical mediators released from inflammatory cells markedly enhances methacholine-induced contraction without elevating intracellular concentrations of Ca(2+). This augmented responsiveness to methacholine involves the phosphorylation of myosin phosphatase targeting protein 1 (MYPT1) via Rho-kinase, however, it is attenuated by pre-treatment with Rho-kinase inhibitors such as Y-27632 and HA-1077. Airway smooth muscle contraction due to asthma-related substances such as contractile agonists and reactive oxygen species is suppressed by these Rho-kinase inhibitors. Reduced responsiveness to beta-adrenergic receptor agonists occurs via Ca(2+) sensitization, after exposure to lysophospholipids and proteases released from inflammatory cells. This beta-adrenergic desensitization is also attenuated in the presence of Y-27632. Furthermore, the proliferation of airway smooth muscle cells is elevated by Rho-kinase, however, it is markedly suppressed by Y-27632. Antigen challenges cause hyperresponsiveness and eosinophilia in the airways; however, these reactions are markedly suppressed by these Rho-kinase inhibitors. These findings indicate that RhoA/Rho-kinase is involved in the pathophysiology of asthma, and suggest that Rho-kinase inhibitors have therapeutic potential for prohibiting these features. In conclusion, RhoA/Rho-kinase is a novel target molecule for the treatment of asthma.
