Beta-adrenergic effects on left ventricular filling: influence of aging and exercise training (1994)

Reduced heart rate and contractile responses to beta-agonist stimulation characterize normal cardiac aging, but whether diastolic responses also decline with aging has not been determined in humans. Diastolic filling responses to isoproterenol were determined in 13 older (60-82 yr) and 11 young (24-32 yr) healthy men before and after endurance training. Filling rates were expressed in three ways: 1) normalized to end-diastolic volume per second, 2) normalized to stroke volume per second, and 3) as absolute milliliters of blood (ml.s-1.m-2). Peak early filling rates by all methods were reduced at rest and all isoproterenol doses with aging (all P < 0.0001 for old vs. young), whereas peak atrial filling rates were increased with aging. During isoproterenol, both peak early and peak atrial filling rates increased significantly (all P < 0.01); the increase in filling rates with isoproterenol was not different with aging (all NS for old vs. young x dose). Endurance training did not augment diastolic filling responses to isoproterenol. Although diastolic filling rates at rest are markedly altered by aging, diastolic filling responses to isoproterenol are not reduced with aging. Thus the age-associated declines in heart rate, ejection fraction, and cardiac output responses to beta-adrenergic stimulation with isoproterenol do not extend to diastolic filling responses.
Real-time error concealment in digital video streams using digital signal processors (2001)

When compressed video is transmitted through a data network, such as an ATM or a wireless network, data can be lost due to channel errors and/or congestion. Techniques that post-process the received video and conceal the errors in real-time are needed. We describe the implementation of an error concealment technique on a fixed-point digital signal processor.
A review of technologies for the transport of digital data in recent physics experiments (2006)

This paper describes past and present techniques and technologies for the transport of digital data in recent physics experiments. After an overview of the typical requirements for modern data acquisition systems in the field of large scale experimental physics, we detail the successes and failures observed over the last 20 years of evolution of high-speed point-to-point link technology, networking standards and products. Modtextern data transport technology is presented along with several applications to experiments under construction. Advanced techniques, emerging technologies and trends in the field of high-speed digital data transport are outlined in the perspective of future experiments.
A southern breeding record of the crimson finch 'Neochmia phaeton' (1988)

The Atlas of Australian Birds (Blakers et al. 1984) contains few records of the Crimson Finch Neochmia phaeton south of 20 degrees S and the species has not been sighted south of 21 degrees S since 1900. Breeding was not recorded south of 20 degrees S during the period of the Field Atlas. Pizzey (1980) suggests a range south to Proserpine (20 degrees 21'S, 148 degrees 36'E) and formerly to Rockhampton (23 degrees 22'S, 150 degrees 32'E) whilst Slater (1974) gave the southern limit at Rockhampton but amended this to Proserpine in 1986 (Slater et al. 1986). I observed a pair of Crimson Finches constructing a nest in a tree on the bank of the Connors River (22 25'S, 148 59'E) during the period 14 - 16 April, 1988.
Gene trap mutagenesis of hnRNP A2/B1: a cryptic 3' splice site in the neomycin resistance gene allows continued expression of the disrupted cellular gene (2003)

Expression of the occupied hnRNP A2/B1 gene and utilization of the viral poly(A) site are consistent with an exon definition model of pre-mRNA splicing. These results reveal a mechanism by which U3 gene trap vectors can be expressed without disrupting cellular gene expression, thus suggesting ways to improve these vectors for gene trap mutagenesis.
Production and Properties of Glass-Ceramic from Incinerator Fly Ash (2003)

To recycle waste materials, the work is concerned with development of a glass-ceramic from a Korean incinerator fly ash with a high content of Cl. As a pre-treatment of ash, water washing the fly ash was used to remove the high Cl content before melting the ash. The process induced internal crystallization of fly ash after melting under a single stage heat treatment without adding nucleating agents into the ash. As a result, fracture stress of 220MPa and fracture toughness of 1.7 MPam 1/2 were found in the glass-ceramic, which were high values compared to others reported. Thus, the present process suggests that a good glass-ceramic produced from an incinerator ash could be applicable for structural materials in terms of economical and environmental points.
An Evaluation of the Role of Properdin in Alternative Pathway Activation on <i>Neisseria meningitidis</i> and <i>Neisseria</i>  <i>gonorrhoeae</i> (2010)

Properdin, a positive regulator of the alternative pathway (AP) of complement is important in innate immune defenses against invasive neisserial infections. Recently, commercially available unfractionated properdin was shown to bind to certain biological surfaces, including Neisseria gonorrhoeae, which facilitated C3 deposition. Unfractionated properdin contains aggregates or high-order oligomers, in addition to its physiological "native" (dimeric, trimeric, and tetrameric) forms. We examined the role of properdin in AP activation on diverse strains of Neisseria meningitidis and N. gonorrhoeae specifically using native versus unfractionated properdin. C3 deposition on Neisseria decreased markedly when properdin function was blocked using an anti-properdin mAb or when properdin was depleted from serum. Maximal AP-mediated C3 deposition on Neisseriae even at high (80%) serum concentrations required properdin. Consistent with prior observations, preincubation of bacteria with unfractionated properdin, followed by the addition of properdin-depleted serum resulted in higher C3 deposition than when bacteria were incubated with properdin-depleted serum alone. Unexpectedly, none of 10 Neisserial strains tested bound native properdin. Consistent with its inability to bind to Neisseriae, preincubating bacteria with native properdin followed by the addition of properdin-depleted serum did not cause detectable increases in C3 deposition. However, reconstituting properdin-depleted serum with native properdin a priori enhanced C3 deposition on all strains of Neisseria tested. In conclusion, the physiological forms of properdin do not bind directly to either N. meningitidis or N. gonorrhoeae but play a crucial role in augmenting AP-dependent C3 deposition on the bacteria through the "conventional" mechanism of stabilizing AP C3 convertases.
Sample-to-Sample Variability and Bit Errors Induced by Total Dose in Advanced NAND Flash Memories (2014)

The variability in the total ionizing dose response of 25-nm single level cell NAND Flash memories from two different lots is studied. More than 1 Terabit of floating gate cells were irradiated with gamma rays and the number of errors was statistically analyzed. The behavior of the two lots is remarkably different in terms of floating gate errors. The statistical parameters such as mean, standard deviation, and shapes of the error distributions were studied. The sample-to-sample statistical distribution of TID errors is not Gaussian and it is attributed to variability in neutral cells, due to phenomena such as random discrete dopant fluctuations. Finally, the impact of scaling on variability is discussed.
ChemInform Abstract: STUDIES OF ORGANOPHOSPHOROCHLORIDATES. REACTIONS OF CHOLESTERYL PHOSPHOROCHLORIDATES WITH ALCOHOLS (1976)

Mapping of alpha-melanocyte-stimulating hormone-like immunoreactivity in the cat diencephalon. (1996)

Using an indirect immunoperoxidase technique, we studied the location of alpha-melanocyte-stimulating hormone-like fibers and cell bodies in the cat diencephalon. In the thalamus, almost all the immunoreactive fibers were found in the midline region, whereas in the hypothalamus immunoreactive fibers were observed in the whole structure. The hypothalamus showed a higher density of both immunoreactive fibers and cell bodies; no immunoreactive neurons were found in the thalamus. The densest network of immunoreactive fibers was observed in the epithalamus (nucleus periventricularis anterior) and in the hypothalamic nuclei filiformis, hypothalami ventromedialis, arcuatus, periventricularis hypothalami, area hypothalamica dorsalis, and hypothalamus posterior. A high density of immunoreactive neurons was found in the nucleus arcuatus, in the hypothalamus lateralis, and in the area hypothalamica dorsalis; a low density was found in the nucleus hypothalami ventromedialis and in the hypothalamus dorsomedialis. By comparison with the studies of previous researchers, these data showed a more widespread distribution of alpha-melanocyte-stimulating hormone-like immunoreactive fibers and perikarya in the feline hypothalamus. Moreover, our findings indicate that the peptide is widely distributed in the cat diencephalon, suggesting that alpha-melanocyte-stimulating hormone might be involved in several physiological functions.
Differential Thermal Analysis of Hydrogen Peroxide Decomposition by Various Evaporated Metal Films (1963)

金属蒸着膜を触媒として,その液相における接触作用機構をしらべるために,過酸化水素の分解反応を速度論的に研究した。反応速度の測定には,示差熱解析法を適用して,一曲線を得る測定のみで速度定数とその温度変化を同時に決定した。反応速度は触媒の蒸着重暴に比例し,活性化エネルギーは反応溶液のρHを増大すれば,直線的に減少した。金属ゾルの場合とほぼ同様に,金属蒸着膜の活性はつぎのような順に低下した。パラジウム,白金,鉄,金,ニヅケル,銀,クロム,銅,アルミニウムo
Web notebooks as a knowledge management tool for system engineering trade studies (2017)

We discuss the use of web notebooks as an integrated tool for conducting and managing engineering trade studies. The value of the notebook form is the ability to capture all typical components of an engineering trade study in a common interactive document form. The notebook form can also be displayed in a slide show mode for interaction with decision makers. An example trade is shown to represent the typical trade study components integrated into a single document form. In an accompanying presentation, an actual notebook would be used for the complete presentation. Application of this approach is being pursued as a knowledge management approach to overcome some of the current disparate capture of trade study text and data across multiple tools forms.
An algorithm for finding nearest neighbours in constant average time with a linear space complexity (2003)

Given a set of n points or 'prototypes' and another point or 'test sample'. The authors present an algorithm that finds a prototype that is a nearest neighbour of the test sample, by computing only a constant number of distances on the average. This is achieved through a preprocessing procedure that computes only a number of distances and uses an amount of memory that grows lineally with n. The algorithm is an improvement of the previously introduced AESA algorithm and, as such, does not assume the data to be structured into a vector space, making only use of the metric properties of the given distance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Adaptive Reed&#150;Solomon Code Protection of Data Partitioned H.264 Video (2009)

Due to the growing interest in video delivery over unreliable channels, the problem of error concealment in video communication is increasingly important. Our goal is to enable the correct decoding of bitstream, on the top of that, have a maximum playable frame rate and video quality. To be able to better combat packet loss, this article proposes a UEP solution in data partitioned H.264 video. Using mathematical expectation we first present the ARUP concept to find an optimal tradeoff between error correction ability of RS code and network capacity. Then we evaluate three different protection schemes. Experimental results show that with the combination of data partition and RS code, our proposal significantly improves the received video quality when packet loss occurs. In the last scheme, our method has at least 10 dB PSNR increase comparing to the stream without RS protection when the packet loss rate is 10%.
A Two-Stage Economic Optimization and Predictive Control for EV Microgrid (2018)

This paper focuses on a two-stage framework for economic optimization to maximize the profits of electric-vehicle (EV) microgrid. In the first stage, an economic optimization problem at the day-ahead time scale is solved to determine the power purchased from load serving entities (LSE), and make an optimal price decision (parking fee and charging fee) while considering with the EVs uncertainties. In the second stage, a real-time model predictive control strategy is proposed to meet the EVs requirement and minimize the operation cost. Through two-stage scheduling, EV microgrid can guarantee long-term safe and efficient operation, while ensuring maximum benefits. The simulation results show that the proposed method in this paper can provide reliable power supply to the EVs, increase the EV microgrid revenue and ensure the safe operation of the EV microgrid system.
Behavior sampling: a recording mechanism for visually based teleoperation (2002)

Proposes a visually based teleoperation with accumulation method and system where the visual and control information sequences are stored and available for syntactically indexed playback. Visually based teleoperation systems heretofore described in the literature unfortunately can only display an instantaneous representation of the control sequence. Past control experience should instead be accumulated and available to facilitate teleoperators. In this paper, the behavior sampling extraction theory and method, the behavior sampling data representation, and portions of the status on demand function-set are introduced. Behavior sampling utilizes semiotic analysis of the teleoperator control behavior to syntactically segment the control motions and the relevant visual objects into a syntactically indexable storage stream. A preliminary system used for manipulating single biological cells under an optical microscope (fitted with a video camera) is described. Repetitive manipulation experiments on Mato fluorescent granular perithelial (FGP) cells show the effectiveness of this enhancement to the visually based control approach.
Solar-Powered Electrochemical Oxidation of Organic Compounds Coupled with the Cathodic Production of Molecular Hydrogen (2008)

A Bi-doped TiO2 anode, which is prepared from a mixed metal oxide coating deposited on Ti metal, is shown to be efficient for conventional water splitting. In this hybrid photovoltaic-electrochemical system, a photovoltaic (PV) cell is used to convert solar light to electricity, which is then used to oxidize a series of phenolic compounds at the semiconductor anode to carbon dioxide with the simultaneous production of molecular hydrogen from water/proton reduction at the stainless steel cathode. Degradation of phenol in the presence of a background NaCl electrolyte produces chlorinated phenols as reaction intermediates, which are subsequently oxidized completely to carbon dioxide and low-molecular weight carboxylic acids. The anodic current efficiency for the complete oxidation of phenolic compounds ranges from 3% to 17%, while the cathodic current efficiency and the energy efficiency for hydrogen gas generation range from 68% to 95% and 30% to 70%, respectively.
T cell responses to a human cartilage autoantigen in the context of rheumatoid arthritis–associated and nonassociated HLA–DR4 alleles (1999)

T cell epitopes of HCgp-39 that were defined in HLA-DR4 transgenic mice stimulated T cells from human subjects carrying RA-associated HLA-DR4 alleles. HLA-DR4 molecules may influence the disease process in RA both by presentation of selected peptide epitopes and by promoting the production of proinflammatory cytokines in synovial joints.
2D Tracking Doppler: A new method to limit spectral broadening in pulsed wave doppler (2012)

Transit time broadening is a major limitation in Pulsed Wave (PW) Doppler, especially when the angle between the flow direction and the ultrasound beam is large. The limited frequency resolution may give severe overestimation of blood velocities, and finer details in the spectral display are lost. By using plane wave transmissions and parallel receive beamforming PW-Doppler signals can be acquired simultaneously in a larger region. This enables tracking of the moving blood scatterers over a longer spatial distance to avoid transit time broadening. In this work, the new method was tested using in vitro and in vivo ultrasound recordings of the carotid artery. The resulting Doppler spectra showed reduced spectral broadening compared to Doppler spectra generated by the Welch's method.
Some Metaphysical Reflections on the Gospel of John (1961)

The author examines the centrality of Jesus in the Gospel of John. Looking at the book of Gospel of John through the lens of metaphysics, the author focuses on the concepts of being, relation, and duality. Specifically, the author looks at being as it applies to Jesus, the relation between the Father and the Son, and the duality of conditions of being, process, and ends. The metaphysical examination confirms the religious claim that all things are centered in Jesus Christ.
Electromechanical coupling and gigahertz elastic properties of ScAlN films near phase boundary (2014)

The electromechanical coupling, elastic properties, and temperature coefficient of elastic constant c33D of ScxAl(1−x)N films with high Sc concentration (x) of 0–0.70 were experimentally investigated. Near the phase boundary, a Sc0.41Al0.59N film exhibited a maximum thickness extensional mode electromechanical coupling coefficient kt2 of 12% (kt = 0.35), which is almost double the value of 6.4% for typical pure AlN films. In the region of 0 &lt; x &lt; 0.2, the electromechanical coupling was confirmed to increase without any detectable deterioration in the temperature stability of c33D (=−54.5 ppm/ °C). This region is favorable in terms of temperature stability and is suitable for wideband resonator filter applications.

Effect of cerebral cortex gangliosides on the clinical and electromyographic evolution of "a frigore" facial paralysis. Apropos of 24 cases. (1978)

Results obtained with gangliosides in cases of frigor facial paralysis were assessed in the light of the clinical and EMG pictures. It was found that early and continuous administration reduced the risk of failure (16% in treated and 66% in untreated subjects).
Relation of molecular structure to in vivo scintigraphic distribution patterns of carbon-11-labeled compounds. 3. Carbon-11-labeled hydantoins (1976)

The preparation and gamma-scintigraphic evaluation of the in vivo distribution patterns in dogs of a series of structurally related hydantoins labeled with the positron emitting, 20.4 min half-life radionuclide, carbon-11 are described. Carbon-11 labeled HCN was collected in water or aqueous Me2SO containing carrier KCN following cyclotron bombardment of 99% N2-1% H2 gas mixture with 22 MeV protons for 1 hr at 25-35 muA. Five 11C-labeled 5,5-dialkylhydantoins, three [11C]diarylhydantoins, five [11C]-5-alkyl-5-phenylhydantoins, and five [11C]spirohydantoins were prepared by heating generally under pressure, a mixture of 11C-labeled KCN, which was produced by isotopic exchange with carrier KCN, the corresponding aldehyde or ketone, and excess (NH4)2CO3 in aqueous ethanol or Me2SO solvent. The 11C-labeled hydantoins were dissolved in 1-1.5% aqueous NaOH for intravenous administration to dogs. Total synthesis time was 70-106 min and 1-59 mCi of final product was available for conducting serial in vivo imaging for up to 2 hr or more with the gamma-scintillation camera. Carbon-11 activity from all compounds showed initial blood-pool distribution with variable concentration of activity in the brain, lungs, liver, and kidney. All of the 11C-labeled diarylhydantoins, and most having one phenyl substituent, and one having a hexamethylene moiety showed initial accumulation of 11C activity in brain. Carbon-11 labeled 5,5-diphenylhydantoin (dilantin) showed the greastest qualitative accumulation of activity in the brain. Those 11C-labeled hydantoins having a carboxyl substituent showed prominent renal concentration and urinary excretion of activity. Most 11-c-labeled hydantoins showed a progressive homogenous whole body distribution of activity in all cellular tissues of the body. The relatively uniform distribution of activity in cellular tissues and slow excretion from the body support the thesis that the pharmacologic action of the hydantoins is related to physical effects on biomembranes rather than to specific chemical interactions with cell constituents.

Coded Bi-directional Relaying (2006)

In this paper, bi-directional traffic between two nodes communicating via a relay node is considered. A novel relaying method based on joint data packet encoding in conjunction with exploitation of a priori known information is presented. Moreover, a specially crafted method for combining of the direct and relayed radio signal is suggested. The proposed scheme enables a reduced number of transmissions, whereby enhancing aggregate throughput. Evaluation, where optimal power and rate settings are derived, shows that the proposed method enhances the throughput up to 33% as compared to a (traditional) four-phase bi-directional protocol under a system energy constraint, both with and without the proposed combining method
Design and Synthesis of 2-Alkylpyrimidine-4,6-diol and 6-Alkylpyridine-2,4-diol as Potent GPR84 Agonists (2016)

A series of alkylpyrimidine-4,6-diol derivatives were designed and synthesized as novel GRP84 agonists based on a high-throughput screening (HTS) hit 1. 6-Nonylpyridine-2,4-diol was identified as the most potent agonist of GPR84 reported so far, with an EC50 of 0.189 nM. These novel GPR84 agonists will provide valuable tools for the study of the physiological functions of GPR84.
