Effects of Age on Contralateral Suppression of Distortion Product Otoacoustic Emissions in Human Listeners with Normal Hearing (2002)

The auditory efferent system presumably plays a role in enhancing signals in noise and, in particular, speech perception in background noise. This study measured the age-related changes of the medial olivocochlear (MOC) system by comparing distortion product otoacoustic emissions (DPOAEs) with and without contralateral white noise stimulation. Otoacoustic emissions were typically reduced in level (magnitude) when white noise was presented to the contralateral ear. This contralateral suppression (CS) is attributed to activation of the MOC system, which has an inhibitory effect on the outer hair cell (OHC) system. By studying CS on cochlear output in human listeners of different ages, it is possible to describe aging effects on the MOC system. Human subjects were young adult, middle aged and old (n = 10/group). All subjects had normal hearing and middle-ear function based upon standard audiometric criteria. The present study recorded 2f(1)-f(2) DPOAE-grams in response to moderate primary tones (L1 = 75, L2 = 65 dB SPL), from 1 to 6.3 kHz. The principal findings were that DPOAE levels were smaller in the old compared to the young group and that CS declined with age for the middle-aged and old groups. In addition, CS in the 1- to 2-kHz range was greater than in the 4- to 6-kHz range for all ages, but especially for the old group. These findings suggest that a functional decline of the MOC system with age precedes OHC degeneration. Moreover, the MOC system maintains better function in the 1- to 2-kHz range than in the 4- to 6-kHz range as a function of age.
Rule-based feature extraction and recognition from STEP file (2003)

Data exchange and system integration have become important considerations in computer-aided systems in order to improve productivity. This has led to the development of a neutral format that is used to facilitate product data exchange between manufacturing components. This paper describes a methodology to extract feature information from a STEP file and recognize features using a rule-based technique.
A dedicated DSP computation engine based on VLSI vector signal processors (2003)

A computation engine (V8) based on eight VLSI vector signal processors (ZSP-322) was developed for dedicated DSP (digital signal processing) applications in areas such as nonparametric spectral estimation, beamforming, Doppler, etc. A design methodology and a set of tools were implemented and tested, facilitating multiprocessor algorithm development and hardware implementation. A novel scheme for assessment of the noise model of a complete system is reported. Multi-V8 implementation schemes for enhanced performance, such as pipelining, computation wave, and interleaving, are discussed and mapped to a quantitative performance space. The internal details of the ZSP-322 device are provided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
What is the role of intra‐operative fluoroscopic measurements to determine tibial tunnel placement in anatomical anterior cruciate ligament reconstruction? (2010)

The hypothesis for this study was that intra-operative fluoroscopic measurements can be used to determine tibial tunnel placement during anatomic anterior cruciate ligament (ACL) reconstruction. The anteromedial (AM) and posterolateral (PL) bundle insertion sites were marked with a thermal device and measured in a consecutive cohort of 67 patients undergoing anatomical ACL reconstruction. For double bundle reconstruction, guide pins were passed in the center of the AM and PL tibial footprints. For single bundle (SB) reconstruction a guide wire was placed between the center of AM and PL footprints. Subsequently, the position of the centers of the AM and PL insertion sites were measured on standardized lateral intra-operative fluoroscopic images. The center for the AM bundle was found to be at 31% (range 20-42%) of the AP distance on the medial joint line and at 35% (range 23-42%) of the AP distance on the Amis and Jakob line. The center of the PL bundle was at 48% (range 37-59%) of the AP distance on the medial joint line and 48% (range 39-58%) of the AP distance on the Amis and Jakob line. The center of the tibial tunnel in the SB group (n = 15) was at 42 and 41% in relation to the medial joint line and the Amis and Jakob line, respectively. Because a significant anatomic variation exists between patients, the decision with respect to tunnel placement should not be merely based on intra-operative fluoroscopic images.
THE DISTRIBUTION AND DISCHARGE OF THUNDERSTORM CHARGE-CENTERS (1955)

The magnitude and location of the charge centers involved in lightning discharges can be determined from the value of the accompanying gradient change at seven points at the ground. Instrumentation, calibration, observation, and analysis techniques for thus locating thunderstorm charge-centers are described. The results of the analysis are presented. The thunderstorm is found to be bipolar, with the negative center at a mean height of 25,000 ft msl or −16C, and with the positive center located about 2000 ft above it. The occasional occurrence of a positive center below the negative center is shown by the record of the leader processes of ground discharges and from other evidence. Comparison is made with the work of Malan and Schonland in South Africa. While the results are in substantial agreement, important differences in the nature of streamer processes and the relative location of the negative centers tapped by successive elements of a single ground discharge are noted. The cold environment found for many of the negative charge centers (as low as −33C) strongly suggests that these centers might not have been produced by a glaze-ice mechanism. Riming and, perhaps, sublimation are probably the important processes for precipitation growth at such low temperatures.

Measurement and calculation of acoustic propagation constants in arrays of small air-filled rectangular tubes (1991)

An experimental and theoretical investigation of sound propagation in a porous sample composed of capillary tubes with rectangular cross sections is described in this paper. An experimental technique valid for low flow resistivity and high porosity porous samples was developed to measure the attenuation and phase velocity in the porous material. This technique uses transmission of a short pulse in a large tube through the porous sample and subsequent frequency domain analysis in the range 200–1300 Hz. Good agreement was obtained if an anomalous tortuosity factor of 1.1 is used in the theory. A scaling factor for relating cylindrical and square tube capillary theories, known as the dynamic shape factor, was investigated. Propagation constants computed from use of a near unity dynamic shape factor in the cylindrical pore theory agree favorably with calculations based on the square pore theory for the frequencies and pore radii used in the experiment.
Carbon Doping in AlGaAs Using Trimethylarsine by Metalorganic Chemical Vapor Deposition with a High-Speed Rotating Susceptor (1995)

We have investigated for the first time carbon (C) doping in AlGaAs using trimethylarsine (TMAs) as an arsenic source by metalorganic chemical vapor deposition with a high-speed rotating susceptor. Hole concentration decreases with increasing growth temperature and V/III ratio, and increases with increasing Al composition. These dependencies of the hole concentration on the growth conditions and the Al composition in AlGaAs are explained by a model which assumes that the thermal decomposition of precursor molecules in the gas phase is considerably suppressed.
Structural, molecular, and genetic analysis of the kilA operon of broad-host-range plasmid RK2 (1991)

The kil loci (kilA, kilB, kilC, and kilE) of incompatibility group P (IncP), broad-host-range plasmid RK2 were originally detected by their potential lethality to Escherichia coli host cells. Expression of the kil determinants is controlled by different combinations of kor functions (korA, korB, korC, and korE). This system of regulated genes, known as the kil-kor regulon, includes trfA, which encodes the RK2 replication initiator. The functions of the kil loci are unknown, but their coregulation with an essential replication function suggests that they have a role in the maintenance or host range of RK2. In this study, we have determined the nucleotide sequence of a 3-kb segment of RK2 that encodes the entire kilA locus. The region encodes three genes, designated klaA, klaB, and klaC. The phage T7 RNA polymerase-dependent expression system was use to identify three polypeptide products. The estimated masses of klaA and klaB products were in reasonable agreement with the calculated molecular masses of 28,407 and 42,156 Da, respectively. The klaC product is calculated to be 32,380 Da, but the observed polypeptide exhibited an apparent mass of 28 kDa on sodium dodecyl sulfate-polyacrylamide gels. Mutants of klaC were used to confirm that initiation of translation of the observed product occurs at the first ATG in the klaC open reading frame. Hydrophobicity analysis indicated that the KlaA and KlaB polypeptides are likely to be soluble, whereas the KlaC polypeptide was predicted to have four potential membrane-spanning domains. The only recognizable promoter sequences in the kilA region were those of the kilA promoter located upstream of klaA and the promoter for the korA-korB operon located just downstream of a rho-independent terminatorlike sequence following klaC. The transcriptional start sites for these promoters were determined by primer extension. Using isogenic sets of plasmids with nonpolar mutations, we found that klaA, klaB, and klaC are each able to express a host-lethal (Kil+) phenotype in the absence of kor functions. Inactivation of the kilA promoter causes loss of the lethal phenotype, demonstrating that all three genes are expressed from the kilA promoter as a multicistronic operon. We investigated two other phenotypes that have been mapped to the kilA region of RK2 or the closely related IncP plasmids RP1 and RP4: inhibition of conjugal transfer of IncW plasmids (fwB) and resistance to potassium tellurite. The cloned kilA operon was found to express both phenotypes, even in the presence of korA and korB, whose functions are known to regulate the kilA promoter. In addition, mutant and complementation analyses showed that the kilA promoter and the products of all three kla genes are necessary for expression of both phenotypes. Therefore, host lethality, fertility inhibition, and tellurite resistance are all properties of the kilA operon. We discuss the possible role of the kilA operon for RK2.
FACTORS ASSOCIATED WITH SUCCESS OF FUEL ETHANOL PRODUCERS (2003)

Economic factors associated with success or failure of dry-mill ethanol plants utilizing corn as a feedstock are analyzed and discussed. A spreadsheet model is used to conduct the analysis based on the assumptions and interactions of various factors. Plant managers and bankers were interviewed in the process of establishing baseline conditions of operation including capital cost per gallon of capacity, ethanol yield per bushel of corn ground, percentage of debt capital, operating expenses of natural gas, electricity, enzymes, chemicals, repairs, labor, and management. Sensitivities were determined and graphed to demonstrate the respective influence of corn price, ethanol price, natural gas price, ethanol yield, capacity factor, and interest rate-debt percent interactions. The model was used to predict the financial performance of a modern, well-sized dry-mill plants if the prices that occurred over the past decade with respect to corn prices, ethanol prices, prices of DDGS and CO2, natural gas prices, and interest rates were to re-play. Rates of returns on equity of dry-mill ethanol plants were compared to rates compiled in the last decade for a group of 200 farmers in southwestern Minnesota. Patterns of loan repayment, influence of technological changes, and the role of government subsidies are discussed.

MFIR filters: Properties and applications (1981)

The class of multiplicative FIR (MFIR) filters is considered and some properties and applications of MFIR filters are investigated. MFIR filter approximation of a given IIR filter is shown to reduce the number of multiplications and additions logarithmically, in comparison to the corresponding FIR filter in direct form. The pure multiplicity property is introduced and is shown to apply to a class of MFIR filters. This property results in a criterion for optimal ordering and expressions for roundoff noise when no scaling is used and also results in the invariance of roundoff noise output under l <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> -scaling.

Structural Characterization of the Conformational Change in Calbindin-D<sub>28k</sub> upon Calcium Binding Using Differential Surface Modification Analyzed by Mass Spectrometry (2009)

Calbindin-D28k is a calcium binding protein with six EF hand domains. Calbindin-D28k is unique in that it functions as both a calcium buffer and a sensor protein. It is found in many tissues, including brain, pancreas, kidney, and intestine, playing important roles in each. Calbindin-D28k is known to bind four calcium ions and upon calcium binding undergoes a conformational change. The structure of apo calbindin-D28k is in an ordered state, transitioning into a disordered state as calcium is bound. Once fully loaded with four calcium ions, it again takes on an ordered state. The solution structure of disulfide-reduced holo-calbindin-D28k has been determined by NMR, while the structure of apo calbindin-D28k has yet to be determined. Differential surface modification of lysine and histidine residues analyzed by mass spectrometry has been used in this study to identify, for the first time, the specific regions of calbindin-D28k undergoing conformational changes between the holo and apo states. Using differential surface modification in combination with mass spectrometry, EF hands 1 and 4 as well as the linkers before EF hand 1 and the linkers between EF hands 4 and 5 and EF hands 5 and 6 were identified as regions of conformational change between apo and holo calbindin-D28k. Under the experimental conditions employed, EF hands 2 and 6, which are known not to bind calcium, were unaffected in either form. EF hand 2 is highly accessible; however, EF hand 6 was determined not to be surface accessible in either form. Previous research has identified a disulfide bond between cysteines 94 and 100 in the holo state. Until now, it was unknown whether this bond also exists in the apo form. Our data confirm the presence of the disulfide bond between cysteines 94 and 100 in the holo form and indicate that there is predominantly no disulfide bond between these residues in the apoprotein.
Immunochemical Examination of the Polysaccharides of Mucorales (1980)

Partially purified serologically active fractions, ACI-B, MHI-B and RNI-B, were separated by affinity chromatography with a con A sepharose column from the supernatant of disrupted mycelium fluid of A. cylindrospora, M. hiemalis and R. niqricans, respectively. These active fractions contained mannose as their Table 5. Inhibition of the precipitation reactions of ACI-B, MHIB and RNI-B with anti-ACE serum by the oligosaccharides Table 6. Chemical analysis of ACI-B, MHI-B, and RNI-B main common component. Six manno-oligosaccharides, which were composed of linear ⋉-(1→6)-linked mannopyranosyl residues, were isolated from the partial acid hydrolysate of pronase-treated exo-cellular glycan of A. cylindrospora. The penta-saccharide and the higher molecular weight oligosaccharides inhibited the precipitin reaction of ACI-B, MHI-B and RNI-B with anti ACE serum. Cross reactivity of anti ACE serum among some Mucorales, the exo-cellular and disrupted supernatant fractions prepared from other fungi was observed only in Mucorales. This suggests that a common serological determinant is present in Mucorales.
The task "template tracking" in a sensor dedicated to active vision (2006)

In this paper, we present a "visual task" which can be considered as a part of a active vision sensor. This task consists in a tracking of gray levels windows of interest. Our approach is based on an efficient matching between hardware architecture and software algorithm. The notion of active detector is introduced in order to take into account the adaptive and local aspect of the processing. To validate our approach, a high speed tracking method based on a CMOS sensor and FPGA is presented. According to the size of the window, the acquisition rate varies from 200 fr/s to 1000 fr/s
Association between glioma susceptibility loci and tumour pathology defines specific molecular etiologies (2012)

The frequency of EGFR and CDKN2A/B risk alleles were largely independent of tumor genetic profile, whereas TERT, RTEL1, CCDC26, and PHLDB1 variants were associated with different genetic profiles that annotate distinct molecular pathways. Our findings provide further insight into the biological basis of glioma etiology.
Video Denoising Based on Inter-frame Statistical Modeling of Wavelet Coefficients (2007)

The paper proposes a joint probability density function to model the video wavelet coefficients of any two neighboring frames and then applies this statistical model for denoising. The parameter of the density function that measures the correlation between the wavelet coefficients of the two frames is used as an index for the motion. The joint density function is employed for spatial filtering of the noisy wavelet coefficients by developing a bivariate maximum a posteriori estimator. A recursive time averaging of the spatially filtered wavelet coefficients is adopted for further noise reduction. Simulation results on test video sequences show an improved performance both in terms of the peak signal-to-noise ratio and the perceptual quality compared to that of the other denoising algorithms
Suppression of Rage as a Basis of Simvastatin-Dependent Plaque Stabilization in Type 2 Diabetes (2006)

This study supports the hypothesis that simvastatin inhibits plaque RAGE expression by decreasing MPO-dependent AGE generation. This effect in turn might contribute to plaque stabilization by inhibiting the biosynthesis of PGE2-dependent MMPs, responsible for plaque rupture.
Altered expression of <i>c-kit</i> and <i>nanog</i> in a rat model of Adriamycin-induced chronic heart failure. (2017)

A small number of cardiac stem cells that express the c-Kit and Nanog biomarkers can be differentiated into myocardial cells, which suggests that these stem cells may be able to repair damage and provide an internal reserve for tissue regeneration. It is unknown, however, whether the levels of myocardial stem cells are altered after heart failure (HF), and whether HF affects the myocardial regenerative ability. In this study, to address this question, we developed a rat model of chronic HF induced by Adriamycin, and examined the morphological changes in c-Kit and Nanog-expressing stem cells in heart tissue of normal and HF rats. We further measured levels of c-Kit and Nanog expression in the hearts of HF vs. healthy control rats using immunohistochemistry, immunofluorescence, and semi-quantitative reverse transcription (RT)-PCR methods. c-Kit and Nanog were expressed in both normal and HF rats; c-Kit was mainly found in and around the epicardial region, whereas Nanog was primarily expressed in vascular endothelium of some myocardial cells and in stem cells. However, expression of both c-Kit and Nanog was significantly decreased in myocardial cells from HF rats, which may be reflective of reduced myocardial regeneration capacity. These findings indicate that HF not only seriously damages the heart muscle cells, but also the cardiac stem cells. This reduced pool of cardiac stem cells and their related factors is likely to be deleterious for tissue repair after myocardial injury.

Social Support and Health Status based on Characteristics of Leisure Activity of Middle-Aged Women (2011)

Purpose: The purpose of this study was to identify social support and health status based on characteristics of leisure activity in middle-aged women. Methods: Participants were 148 middle-aged women living in the capital area. Data were collected through self-report questionnaires which were constructed to include leisure activity characteristics, social support and Brodman's CMI. Data were analyzed using t-test, and ANOVA, with SPSS/WIN 14.0. Results: Social support was different depending on leisure type, leisure partner, length of participation in present activity, regularity, and motivation to start activity. Health status was different depending on the length of participation in present activity, and regularity. Conclusion: Because social support and health status depend on characteristics of leisure activity, further study in nursing one how to resolve the physical, psychological, social and health problems that middle-aged women might experience through various leisure activities.
Common Rail Injector with Injection Rate Control (1998)

<div class="htmlview paragraph">A Common Rail injector with Injection Rate Control (IRC) has been conceived, designed and tested on a hydraulic injector test bench. The opening of the injector's nozzle needle valve is electro-hydraulically controlled by a double-stop solenoid valve. When the solenoid valve moves only through the first stop, the needle valve opens slowly. When it moves through the first and second stops, the needle valve opens fast. In the first part of the injection event it is therefore possible to switch from a low to a high fuel injection rate, whereas the switch-over point can be selected electronically. The proposed design allows to maintain the flexibility of a conventional common rail injector with or without pilot in-jection and adds the feature of a fully controllable initial shape of the injection rate.</div>
