Supplemental Stimulation of Premature Infats: A Treatment Model (1997)

Examined the human infant literature on supplemental stimulation to delineate a course of intervention based on the ontogeny of the nervous system and the impact that systematic stimulation may have on behavioral organization in the premature infant. Effects of vestibular, tactile/kinesthetic, auditory, and oral stimulation are discussed with respect to their similarity to the intra- or extra-uterine environment. Long-standing theoretical and methodological problems are discussed, and a "sequential multimodal treatment model" is introduced.
Long-Term Food Regulation in the Obese and Nonobese* (1971)

Six obese and 5 normal adult male subjects were fed an all-liquid diet ad libitum. For 3 obese and 3 normal subjects, the diet was high calorie during the first 5 days, and low calorie during the second 5 days. For the other subjects, the order was reversed. No subject could identify the caloric level by taste alone. Subjects showed incomplete caloric adjustment; thevolumeof their intake was greater when the food was low calorie than when it was high calorie, but they consumed more calories when the food was high calorie. The only variable which differentiated between obese and normal subjects was hunger ratings. The obese subjects' ratings increased progressively as the experiment progressed. Normal subjects' ratings were consistently low throughout the experiment. This difference in hunger ratings was attributed to a difference in response to the presence of nonexperimental food--ie, the obese subjects' hunger was appetitive, and the normal subjects' was physiologic.
The effect of backside films on rapid thermal oxidation (RTO) growth on silicon wafers (2002)

The effect of backside films, namely silicon dioxide, silicon nitride and bare silicon on rapid thermal oxidation (RTO) growth on silicon wafers by the rapid thermal annealing technique was systematically studied. There was also a comparison study on the effect of doped backside films with phosphorus at 4/spl times/10/sup 14/ atoms/cm/sup 2/ by ion implantation at 100 keV and the undoped films. The RTO layer thickness has been measured by ellipsometry and the target thickness was 10 nm. The rapid thermal annealing system used was the AG Associates 2146 Heatpulse model. The temperature chosen was 1100/spl deg/C. It was demonstrated that thinner RTO layers could be obtained by having sufficient silicon dioxide film at the backside; however, the presence of doped backside layers has no effect on the tunnel oxide growth.

An ETF Trading Decision Support System by Using Neural Network and Technical Indicators (2006)

This paper proposed a neural network based decision support system (DSS) to provide investors with suggestions on transaction timing and transaction strategies of Taiwan 50 index exchange traded funds (ETF). Various indicators were employed with corresponding application principles as the neural network underwent assigned training and learning procedures. It was revealed in the study results that the simulated transaction behavior following recommendations by the proposed system yielded better profits than solely applying Taiwan's weighted stock index.
Decoration of flux pinning positions in YBa2Cu3O7−δ superconductors (1988)

Flux pinning in the sintered high Tc oxide superconductors, YBa2Cu3O7−δ, in the vortex state has been demonstrated for the first time using the Bitter pattern technique and scanning electron microscopy. External magnetic fields of 150 or 800 G perpendicular to the specimen surfaces were applied during the evaporation of cobalt after the specimens cooled with liquid nitrogen had reached a temperature below Tc. All specimens thus decorated with cobalt show nonuniformly distributed flux pinning positions as would be expected due to the porosity and multiphase character of the specimens as well as the relatively low field applied.
Selective silicon epitaxial growth at 800 °C by ultralow-pressure chemical vapor deposition using SiH4 and SiH4/H2 (1989)

This paper presents results of selective Si epitaxial growth at 800 °C on (100) silicon wafers with oxide patterns by ultralow-pressure chemical vapor deposition using pure SiH4 and SiH4/H2. Prior to deposition, the patterned wafers were in situ argon plasma sputtered at −100 V dc bias to remove native oxide. About 800 Å of Si epitaxial layer can be grown selectively on the exposed silicon windows using 3.5 mTorr of SiH4. By flowing H2 with SiH4 during deposition, selective epitaxial layers can be grown to a thickness of 1300 Å before polycrystalline silicon begins to nucleate on the SiO2 surfaces. The epitaxial films were examined by scanning electron microscopy and cross-sectional transmission electron microscopy and found to be of high structural quality. H2 was found to significantly improve the epi/substrate interface and the surface morphology of the epitaxial layers.
Chain Growth and Iron Nitrides in the Fischer—Tropsch Synthesis (1983)

Developments in the Fischer-Tropsch synthesis at the Bureau of Mines from 1945 to 1960 include a simple mechanism for chain growth and the use of iron nitrides as catalysts. The chain-growth schene can predict the carbon-number and isomer distributions for products from most catalysts with reasonable accuracy using only 2 adjustable parameters. Iron nitrides are active, durable catalysts that produce high yields of alcohols and no wax. During the synthesis, the nitrides are converted to carbonitrides.
Chronic inflammation: a failure of resolution? (2006)

Inflammation has evolved as a protective response to insult or injury, it's a primordial response that eliminates or neutralises foreign organisms or material, the resolution of inflammation encompasses the endogenous anti-inflammatory mechanisms that protect us against excessive tissue injury and promote the restoration of tissue structure and function. In fact, our well being and survival depends upon its efficiency and carefully-balanced control. In general, the innate inflammatory response initiates within minutes and, if all is well, resolves within hours. In contrast, chronic inflammation persists for weeks, months or even years. Here, we are going to discuss the key endogenous checkpoints necessary for mounting an effective yet limited inflammatory response and the crucial biochemical pathways necessary to prevent its persistence.
Impact of Si substrate nitridation on electrical characteristics of Ta<sub>2</sub>O<sub>5</sub>stack capacitors (2007)

A comparison of the effect of rapid thermal nitridation (RTN) of the Si surface in N2O and NH3 ambient at different temperatures (700?850??C) on the dielectric and electrical characteristics of thin (~20?nm) Ta2O5 stacks has been made. The electrical parameters of capacitors (film permittivity, oxide charge, densities of bulk traps, interface and slow states, leakage current) are discussed in terms of the impact of N incorporation in the interface region. The films on both types of RTN-treated Si exhibit ~100 times lower leakage current than Ta2O5 on bare Si, but among the two RTN processes NH3 nitridation is more beneficial since only it simultaneously increases also the stack permittivity. This improvement in parameters is suggested to be due to a real nitridation of Si surface which occurs under the NH3 rapid thermal process. RTN in N2O does not produce resistance to the oxidation substrate and it could explain the observed lack of stack dielectric constant improvement. The composition of the interfacial layer under NH3 RTN appears to be TaSi-oxinitride-like, while the interface region at N2O-nitrided Si seems to be SiO2-like. Each RTN process, however, modifies the Si surface and constitutes a specific interface layer different from that at the bare Si substrate. The composition of this layer defines parameters of the traps close to the substrate, the barrier height at the Ta2O5/interface layer and influences the conduction mechanisms in the stacks.
<i>Saccharomyces cerevisiae</i> Multidrug Transporter Qdr2p (Yil121wp): Localization and Function as a Quinidine Resistance Determinant (2004)

This work reports the functional analysis of Saccharomyces cerevisiae open reading frame YIL121w, encoding a member of a family of drug:H(+) antiporters with 12 predicted membrane-spanning segments (DHA12 family). Like its close homologue Qdr1p, Yil121wp was localized at the plasma membrane, and its increased expression also led to increased tolerance to the antiarrhythmia and antimalarial drug quinidine. The quinidine resistance phenotype was confirmed for different yeast strains and growth media, including a prototrophic strain, and YIL121w was named the QDR2 gene. Both QDR1 and QDR2 were also implicated in yeast resistance to the herbicide barban (4-chloro-2-butynyl [3-chlorophenyl] carbamate), and the genes are functionally interchangeable with respect to both resistance phenotypes. The average intracellular pH of a yeast population challenged with quinidine added to the acidic growth medium was significantly below the intracellular pH of the unstressed population, suggesting plasma membrane permeabilization by quinidine with consequent increase of the H(+) influx rate. For the same extracellular quinidine concentration, internal acidification was more intense for the Deltaqdr2 deletant compared with the parental strain. Although QDR2 transcription was not enhanced in response to quinidine, the results confirmed that Qdr2p is involved in the active export of quinidine out of the cell, thus conferring resistance to the drug.
A Survey on Personal Data Cloud (2014)

Personal data represent the e-history of a person and are of great significance to the person, but they are essentially produced and governed by various distributed services and there lacks a global and centralized view. In recent years, researchers pay attention to Personal Data Cloud (PDC) which aggregates the heterogeneous personal data scattered in different clouds into one cloud, so that a person could effectively store, acquire, and share their data. This paper makes a short survey on PDC research by summarizing related papers published in recent years. The concept, classification, and significance of personal data are elaborately introduced and then the semantics correlation and semantics representation of personal data are discussed. A multilayer reference architecture of PDC, including its core components and a real-world operational scenario showing how the reference architecture works, is introduced in detail. Existing commercial PDC products/prototypes are listed and compared from several perspectives. Five open issues to improve the shortcomings of current PDC research are put forward.
Difference between free circulating plasma and serum DNA in patients with colorectal liver metastases. (2002)

This difference between plasma and serum reflects an in vitro process that occurs during clotting. High DNA increase in serum represents an indirect, yet tumour-related process. Plasma DNA levels better represent in vivo levels of circulating DNA. This has implications forfuture studies.
Tube burner studies of cryogenic solid combustion (1997)

The tube burner was developed to quantify the regression rate and combustion efficiency of fastburning cryogenic solids. The project objective was to demonstrate that fuels which are gases or liquids at room temperature could be condensed and burned as cryogenic solids in a controlled manner, which would support the idea that high energy density material (HEDM) could be burned as an additive in solid cryogenic fuel, e.g., solid hydrogen. We have now measured regression rates and mixing/combustion efficiencies of ten cryogenic solid hydrocarbon fuels with the tube burner under conditions where hybrid rockets operate, i.e., pressure and mass flux up to 800-psi and 60-g/cm2-s. Ported fuel cylinders with outside diameter of 0.9inch, port diameter of 0.4-inch, and lengths of 3inches and 6-inches have been burned with gaseous oxygen mass flow rates ranging from 5- to 30-grams per second. Regression rates of the cryogenic solid hydrocarbons are between two and eight times faster than conventional hybrid rocket fuels, e.g., Plexiglas and HTPB. Pentane, the most extensively studied fuel, burns four times faster than HTPB. Combustion efficiency is degraded by incomplete mixing of fuel and oxidizer, which was more pronounced in burns of 6-inch fuel cylinders, where O/F ~ 1, than in burns of 3-inch fuel cylinders, where O/F ~ 2. Higher pressure burns improved combustion efficiency of the shorter cylinders more than the longer cylinders. Maximizing specific impulse in propulsion applications requires that hydrocarbons be burned fuel rich to produce the lightweight CO combustion product rather than CO2. This paper reports on burns of 3-inch pentane cylinders at the near optimum O/F ~ 2.5.

Clustering and classifying enzymes in metabolic pathways: some preliminary results (2002)

The goal of this study was to compare the lipid lowering properties of maritime pine and fish oils in apolipoprotein E-deficient (KOE) mice, an animal model of hyperlipidemia. KOE mice were supplemented with either lard, fish or maritime pine oil (10% w/w) for one month. Compared to lard, fish and maritime pine oils decreased cholesterol (-31% and -52% respectively) and phospholipid (-41 and -52%) levels and increased triglyceride (+182% and +123%) levels. These lipid changes resulted in an enrichment in triglycerides and a depletion in cholesterol of VLDL+IDL plasma fraction as compared to lard-fed mice. These findings suggest that VLDL-triglyceride lipolysis is impaired in KOE mice fed fish or maritime pine oil.
Targeting TNFR2 as a Novel Therapeutic Strategy for Alzheimer’s Disease (2019)

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia. Accumulating experimental evidence shows the important linkage between tumor necrosis factor-α (TNF) and AD, but the exact role of TNF in AD is still not completely understood. Although TNF-inhibitors are successfully used for treating several diseases, total inhibition of TNF can cause side effects, particularly in neurological diseases. This is attributed to the opposing roles of the two TNF receptors. TNF receptor 1 (TNFR1) predominantly mediates inflammatory and pro-apoptotic signaling pathways, whereas TNF receptor 2 (TNFR2) is neuroprotective and promotes tissue regeneration. Therefore, the specific activation of TNFR2 signaling, either by directly targeting TNFR2 via TNFR2 agonists or by blocking TNFR1 signaling with TNFR1-selective antagonists, seems a promising strategy for AD therapy. This mini-review discusses the involvement of TNFR2 and its signaling pathway in AD and outlines its potential application as therapeutic target. A better understanding of the function of TNFR2 may lead to the development of a treatment for AD.
Axicon lens-based cone shell configuration for depth-sensitive fluorescence measurements in turbid media (2013)

We have developed a novel noncontact setup to implement a cone shell illumination and detection configuration using axicon lenses for depth-sensitive fluorescence measurements. The setup was demonstrated experimentally to be capable of detecting fluorescence from a two-layered turbid agar phantom with a larger sensitivity to the deep layer and a larger range of sensitivity to either layer than a conventional cone configuration implemented by a microscope objective lens. Furthermore, the axicon lens-based setup eliminates the need of moving the objective lens up or down to achieve depth-sensitive measurements, which effectively improves the consistency of optical coupling and thus would be preferred in a clinical setting.
Image registration using autolandmark (2004)

AutoLandmark is a fully automated image registration technique capable of performing real time landmark registration. It's based on a correlation algorithm used to match the shoreline of a measured landmark to the corresponding shoreline extracted from a digital map. A cloud detection process implemented in AutoLandmark identifies cloudy pixels to avoid erroneous measurements from cloudy scenes. The validity of a measurement obtained with Autolandmark is determined by a quality metric (QM) which is calculated using several factors including the goodness-of-fit of the matching algorithm, scene cloudiness, and scene contrast. AutoLandmark is implemented in the Replacement Product Monitor (RPM) for landmark registration of the Geostationary Operational Environmental Satellite (GOES) imagery with subpixel accuracy. The RPM is part of the GOES Spacecraft Ground System and has been operational since 2001, producing more than a thousand daily landmark measurements.
Conjugated Polymer and Triphenylamine Derivative Codoped Nanoparticles for Photothermal and Photodynamic Antimicrobial Therapy (2020)

The photothermal conjugated polymer (DPPT-TT) and a triphenylamine derivative (DPATP-CN) codoped nanoparticles (DDNPs) were designed and prepared via self-assembly. The obtained DDNPs exhibit both efficient and stable photothermal properties and excellent ROS production capability to synergistically achieve photothermal therapy (PTT) and photodynamic therapy (PDT). DDNPs showed antimicrobial activity with more than 70%, 90%, and 99% inhibition ratio, respectively, toward Gram-(-) bacteria (<i>E. coli</i>), Gram-(+) bacteria (<i>S. aureus</i>), and fungi (<i>C. albicans</i>) under combined irradiation of near-infrared light and white light. Therefore, DDNPs are broad-spectrum antimicrobial materials and provide a significant perspective to select an appropriate sterilization strategy for different microorganisms.
Effect of Thoracic Duct Decompression on Ascites (1968)

Decompression of the thoracic lymph duct reportedly causes regression of ascites. Four patients were studied under careful conditions of metabolic balance during thoracic duct drainage and reinfusion of lymph. Decompression alone did not change the ascites. If a negative water and sodium balance was produced, such as by dialysis of the lymph, a corresponding reduction in ascites was effected. This effect was similar to the results from paracentesis, diuretics, or ascites autotransfusion. In one patient, ascites autotransfusion resulted in a four-fold increase in the lymph flow rate. It is postulated that the accelerated lymph flow resulted from an expansion of the plasma volume by ascites, which resulted in an increased blood flow to the liver and an increased transudation of lymph at the postsinusoidal block.
A reverse VSP tomographic velocity analysis (2000)

Tomographic velocity analysis of VSP or reverse VSP is simplified here using Earth models with constant interval velocities separated by planar interfaces (PI). The traveltime formulas in such PI models are given. The formulas can be used to invert simultaneously for interval velocity, interface geometry, and positions of shots and geophones, though we shall always try to minimize the inversion variables based on given data and a priori information. The algorithm works for synthetic and physical model data tested so far. Practical issues such as event identification, choice of inversion variables, and their resolvability with reverse VSP data are discussed.
Dynamic compensation of capacitive voltage transformers (1998)

This paper presents the digital algorithm for on-line dynamic compensation of the secondary voltage of a capacitive voltage transformer (CVT). The adopted CVT model together with the assumed simplifications is given first. Next, the compensating algorithm based on digital inversion of the CVT transfer function is derived. Frequency domain analysis and quantitative evaluation of the compensation follow. The ATP-EMTP simulations are included that show the improvement of the measurement of protective criteria quantities as a result of dynamic compensation of a CVT.
The rate of heat storage mediates an anticipatory reduction in exercise intensity during cycling at a fixed rating of perceived exertion (2006)

The aim of the present study was to examine the regulation of exercise intensity in hot environments when exercise is performed at a predetermined, fixed subjective rating of perceived exertion (RPE). Eight cyclists performed cycling trials at 15 degrees C (COOL), 25 degrees C (NORM) and 35 degrees C (HOT) (65% humidity throughout), during which they were instructed to cycle at a Borg rating of perceived exertion (RPE) of 16, increasing or decreasing their power output in order to maintain this RPE. Power output declined linearly in all three trials and the rate of decline was significantly higher in HOT than in NORM and COOL (2.35 +/- 0.73 W min(-1), 1.63 +/- 0.70 and 1.61 +/- 0.80 W min(-1), respectively, P < 0.05). The rate of heat storage was significantly higher in HOT for the first 4 min of the trials only, as a result of increasing skin temperatures. Thereafter, no differences in heat storage were found between conditions. We conclude that the regulation of exercise intensity is controlled by an initial afferent feedback regarding the rate of heat storage, which is used to regulate exercise intensity and hence the rate of heat storage for the remainder of the anticipated exercise bout. This regulation maintains thermal homeostasis by reducing the exercise work rate and utilizing the subjective RPE specifically to ensure that excessive heat accumulation does not occur and cellular catastrophe is avoided.
