Intersubject and intrasubject variability of gastric volumes in response to isocaloric liquid meals in functional dyspepsia and health<sup>2</sup> (2007)

Gastric emptying (GE) has a considerable variability, but data on reproducibility of gastric volume measurements are sparse. We aimed to study the reproducibility of postprandial gastric volume responses and GE using magnetic resonance imaging (MRI) in healthy controls (HC) and patients with functional dyspepsia (FD). Eight HC and eight FD patients underwent a MRI study on two occasions. MR images were acquired in seated position before and up to 120 min after liquid meal administration (200 mL, 300 kcal). Fasting (V0), initial postprandial stomach volumes (V1), volume changes (V1 - V0) and meal emptying half-times (T 1/2) were determined. Intersubject and intrasubject coefficients of variation (CV(inter), CV(intra)) and Pearson's correlation coefficients (r) were calculated. T 1/2 on both occasions were (mean +/- SD) 113 +/- 28 and 121 +/- 30 min in HC (ns) and 127 +/- 31 and 128 +/- 37 min in FD (ns), respectively. In HC, CV(inter), CV(intra), r were 31%, 23%, 0.49 for V0; 13%, 7%, 0.68 for V1; 10%, 4%, 0.71 for V1 - V0 and 25%, 7%, 0.90 for T 1/2. In FD these parameters were for V0: 42%, 41%, -0.06; for V1: 18%, 10%, 0.40; for V1 - V0: 20%, 14%, 0.74 and for T 1/2: 26%, 10%, 0.84. The stomach accommodates to a given meal volume, resulting in similar and reproducible postprandial volumes within- and between-subjects. MRI provides reproducible measurements of gastric volume responses in health and disease.
Assembly of an XGA 0.9" LCOS display using inorganic alignment layers for VAN LC (2002)

An assembly process for LCoS microdisplays using inorganic alignment layers has been developed. The specific problems emerging when using this approach were identified and solved. This enables the production of extremely high contrast, fast display devices when using the VAN LC mode.
Synthesis of 5-Arylpyrrole-2-carboxylic Acids as Key Intermediates for NBD Series HIV-1 Entry Inhibitors (2017)

5-Arylpyrrole-2-carboxylic acids are important key intermediates in the synthesis of HIV-1 entry inhibitors (such as NBD-11021 and NBD-14010). Here we present a general method for the synthesis of some 5-arylpyrrole-2-carboxylic acids in three steps starting from pyrrole. By this method, the compounds could be prepared on gram scale and without chromatographic purification.
Fluid microstructure interaction based air flow sensor (2019)

Fluid structure interaction (FSI) of Polydimethylsiloxane (PDMS) microcantilever under fluid flow was studied for air flow sensing application. 3x8x0.250 mm microcantilever was used for the study. A low speed mini wind tunnel which provides laminar flow inside the test section was used. The micro cantilever was subjected to fluid load with flow rate up to 360ml/s. COMSOL simulation was performed using FSI module to test the microcantilever deflection. It was found that the deflection of the microcantilever beam increases with increase in fluid flowrate. Experimental result are in agreement with simulation results.
Surface plasmon resonance in CdSe semiconductor coated with gold nanoparticles (2008)

We have grown CdSe semiconductor films on glass substrates and the films were coated with Au nanoparticles of 10 nm in size by the pulsed-laser deposition technique. The films demonstrate a large enhancement of Raman intensity and photoluminescence of CdSe semiconductor via excitation of surface plasmon resonances in proximate gold metal nanoparticles deposited on the surface of CdSe film. These observations suggest a variety of approaches for improving the performance of devices such as photodetectors, photovoltaics, and related devices, including biosensors.

Healthy aortic hemodynamics are dependent on subject age, and correlate with vessel diameter and cardiac function.
Detection and Severity Assessment of Peripheral Occlusive Artery Disease via Deep Learning Analysis of Arterial Pulse Waveforms: Proof-of-Concept and Potential Challenges (2020)

Toward the ultimate goal of affordable and non-invasive screening of peripheral occlusive artery disease (PAD), the objective of this work is to investigate the potential of deep learning-based arterial pulse waveform analysis in detecting and assessing the severity of PAD. Using an established transmission line model of arterial hemodynamics, a large number of virtual patients associated with PAD of a wide range of severity and the corresponding arterial pulse waveform data were created. A deep convolutional neural network capable of detecting and assessing the severity of PAD based on the analysis of brachial and ankle arterial pulse waveforms was constructed, evaluated for efficacy, and compared with the state-of-the-art ankle-brachial index (ABI) using the virtual patients. The results suggested that deep learning may diagnose PAD more accurately and robustly than ABI. In sum, this work demonstrates the initial proof-of-concept of deep learning-based arterial pulse waveform analysis for affordable and convenient PAD screening as well as presents challenges that must be addressed for real-world clinical applications.

Suppression of gas separation membrane plasticization by homogeneous polymer blending (2001)

Abstract Plasticization is a phenomenon frequently encountered in the application of glassy polymeric materials for solution–diffusion membranes. Conventional methods for stabilizing the membrane are either annealing or cross‐linking, which hardly influence the selectivity of the membrane, but decrease the permeability. For single‐gas experiments, the literature shows that plasticization can be stabilized by blending a polymer with high plasticization tendencies with one that is hardly affected by the sorbed molecules. Most permeation experiments are carried out with pure CO 2 , but little is known about the transport properties determined from mixed gas experiments. Stabilization of plasticization in mixed‐gas experiments for polymer blends of the polyimide Matrimid and polysulfone is reported, as well as transport properties of a new homogeneous polymer blend based on Matrimid and the copolyimide P84. Experimental results show that the material is stabilized against carbon dioxide plasticization and selectivity for a carbon dioxide/methane mixture significantly improves.
Account: Mass spectrometry in the combinatorial chemistry revolution (1997)

The integration of mass spectrometry and combinatorial chemistry is becoming commonplace in many laboratory settings. Combinatorial chemistry provides a means for synthesis of mixtures of large numbers of compounds, thereby greatly increasing the diversity of molecular architectures available for screening. Mass spectrometry is being utilized as a rapid and sensitive tool not only to characterize combinatorial libraries, but also to aid in the identification of active compounds.
Electrochemical Study of Redox Reaction of Various Gold III Chloride Concentrations in Acidic Solution (2018)

The redox reaction of gold III chloride in acid solutions has been electro-chemically investigated using a cyclic voltammetry technique. This paper emphasizes the current and potential sites at which gold III chloride is reduced in hydrochloric acid that is vital to electrochemical evaluation of gold recovery. The solutions were prepared by reacting HCl with AuCl3 in various concentrations thus 30 and 60 mg/L AuCl3 in 0.1 and 0.5 M HCl, respectively. Solutions of 0.1 and 0.5 M HCl containing 0, 30 and 60 mg/L AuCl3, respectively were tested for possible reduction and oxidation reactions by cyclic voltammogram experiment using a glassy carbon, a saturated calomel and a platinum wire mesh as working, reference and counter electrodes, respectively. The results showed no peak in the case of the absence of AuCl3 in the solutions, but appreciable cathodic and anodic peaks for the reduction and oxidation of various concentrations of AuCl3 in acid solutions. The reaction between AuCl3 and HCl was found to be reversible because the ratio of oxidation peak current and reduction peak current was 1. The concentration of AuCl-4 on the surface of the working electrode at the reduction site for each AuCl3 concentration using Nernst equation was 1.22 × 109 ppm and 2.44 × 109 ppm. The reduction potentials were independent of concentration, while the current was highly dependent of concentration.
Characterization of the ICSI‐mediated gene transfer method in the production of transgenic pigs (2011)

Understanding the behavior of transgenes introduced into oocytes or embryos is essential for evaluating the methodologies for transgenic animal production. We investigated the expression pattern of a transgene transferred to porcine eggs by intracytoplasmic sperm injection-mediated gene transfer (ICSI-MGT) or pronuclear microinjection (PN injection). The introduction of the EGFP gene by ICSI-MGT yielded significantly more embryos with non-mosaic transgene expression (P < 0.01). In the ICSI-MGT group, 61.5% (24/39) of the embryos were EGFP-positive in all their component blastomeres at the morula stage, while fewer than 10% of such embryos were EGFP-positive in the PN-injection group. Using three types of transgenes, ranging from 3.0 to 7.5 kb in size, we confirmed that approximately one in four fetuses obtained by ICSI-MGT was transgenic, suggesting that ICSI-MGT is a practical method for transgenic pig production. Southern blot analysis of 12 transgenic fetuses produced by ICSI-MGT revealed that the number of integrated transgene copies varied from 1 to 300, with no correlation between transgene size and the number of integrated copies. Fluorescence in situ hybridization analysis revealed that the transgenes were randomly integrated into a single site on the host chromosomes. Together, these data indicate that multiple-copy, single-site integration of a transgene is the primary outcome of ICSI-MGT in the pig and that ICSI-MGT is less likely than PN injection to cause transgene integration in a mosaic manner.
Design of a multi-functional metamaterial inspired dipole antenna (2010)

In this contribution, we present the theoretical analysis and the design of a multi-functional dipole antenna based on the employment of artificial magnetic metamaterials (AMM). The AMM consists of an anisotropic dispersive volumetric material, whose permeability follows the Lorentz model. We show that a regular dipole antenna placed above a slab of such material may efficiently work in different operation modes. We validate the proposed setup through a set of full-wave simulations, discussing performances and suggesting solutions for a possible actual implementation.

Neural pathways of cardiovascular depressor reflex during gastric distension and its modulation by electroacupuncture (2008)

Mild mechanical gastric distension (GD) frequently evokes a decrease in blood pressure and bradycardia. We hypothesized that the GD‐induced cardiovascular depressor reflex is transmitted through both sympathetic and parasympathetic afferent pathways. We also hypothesized that it can be modulated by electroacupuncture (EA) and is mediated by caudal ventral lateral medulla (cVLM) and nucleus ambiguus (NA). Sprague‐Dawley rats were anesthetized, ventilated, and their mean arterial blood pressures (MAP) and heart rates (HR) monitored. Repeated balloon inflation of the stomach every 10 minutes to 15–20 mmHg gastric wall tension induced consistent falls in MAP and HR. This inhibitory response was reversed by chemical denervation of celiac ganglia and intra‐abdominal vagal nerves with 0.1mL of 1% lidocaine, suggesting that the decreased MAP was mediated by both the withdrawal of sympathetic tone and increased parasympathetic tone. Similarly, the reduced HR was reversed after vagotomy and celiac ganglionectomy. Bilateral stimulation with EA at cardiovascular acupoints P5‐6 for 30 min significantly decreased the depressor response. This modulation lasted for 50 min. Unilateral microinjection of atropine into cVLM immediately after termination of EA reversed the inhibition by EA, whereas microinjection of normal saline into cVLM did not reverse it. Microinjection of gabazine into the NA reversed the inhibition by EA. These data suggest that GD activates both sympathetic and vagal afferents to evoke reflex cardiovascular sympatho‐ and parasympatho‐inhibition through the cVLM and NA respectively. EA attenuates the cardiovascular depressor reflex through a cholinergic mechanism in the cVLM and a gabanergic mechanism in the NA.
FDG PET studies during treatment: Prediction of therapy outcome in head and neck squamous cell carcinoma (2002)

Background Positron emission tomography (PET) provides metabolic information of tissues in vivo. The purpose of this study was to assess the value of PET with 2-[18 F] fluoro-2-deoxy-D-glucose (FDG) in prediction of therapy outcome (tumor response, survival, and locoregional control) in locally advanced HNSCC. Methods Between 1993 and 1999 47 patients underwent PET before (PET1) and after (PET2) 1 to 3 weeks of radical treatment with evaluation of metabolic rate (MR) and standardized uptake value (SUV) of FDG. All patients received radiotherapy, and 10 also received neoadjuvant chemotherapy. Median follow-up time was 3.3 years. Results Low and high MR FDG at PET2, with median value as cutoff, was associated with complete remission in 96% and 62% (p = .007), with 5-year overall survival in 72% and 35% (p = .0042) and with local control in 96% and 55% (p = .002), respectively. Conclusions FDG PET in the early phase of treatment of HNSCC is associated with tumor response, survival, and local control. © 2002 John Wiley & Sons, Inc.
Experimental and Analytical Study of Temperature Swing Piston Coatings in a Medium-Duty Diesel Engine (2022)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;The use of Thermal Barrier Coatings (TBCs) has been shown to be a promising technology to improve internal combustion engine efficiencies by reducing heat rejection to the coolant and oil. In recent studies, temperature swing coatings that have simultaneously low volumetric heat capacity and low thermal conductivity have been shown to be particularly promising in this regard. In this study, a traditional and a newer swing coating are applied to the piston of an on-road medium-duty diesel engine to assess the benefits of their use. An analytical wall temperature model is coupled to the 1-D engine simulation software GT-POWER and predictions of wall temperature, heat transfer and chemical heat release rate are presented. The swing coating is found to yield an ~1.2% efficiency benefit at the highest load condition studied alongside an 80°C improvement in exhaust temperature at the lowest load condition studied compared to a reference uncoated piston. Further, the traditional TBC was not found to have a significant efficiency advantage over the reference uncoated piston, highlighting the promise of the swing coating in improving the thermal efficiency of on-road diesel engines.&lt;/div&gt;&lt;/div&gt;
Radiation Dose Dependence of the Sensitization by Oxygen and Oxygen Mimic Sensitizers (1985)

New and old evidence is discussed which suggests that the oxygen enhancement ratio (OER) is decreased at lower radiation doses as compared with that of higher radiation doses. In addition, there is evidence that cells irradiated in severe hypoxia have an impaired ability to recover from sublethal damage. However, there is also contrary evidence to these observations. Thus the suggestions that oxygen is not strictly a dose modifying agent have been controversial from the very beginning. It is hoped that new experimental undertakings currently performed in many different laboratories will resolve these issues as well as explain the controversy which has lasted more than 25 years in this field of radiobiologic research.
Non Cooperative Game Theoretic Approach for Residential Energy\n Management in Smart Grid (2019)

Demand side management (DSM) is one of the main functionalities of the smart\ngrid as it allows the consumer to adjust its energy consumption for an\nefficient energy management. Most of the existing DSM techniques aim at\nminimizing the energy cost while not considering the comfort of consumers.\nTherefore, maintaining a trade-off between these two conflicting objectives is\nstill a challenging task. This paper proposes a novel DSM approach for\nresidential consumers based on a non-cooperative game theoretic approach, where\neach player is encouraged to reshape its electricity consumption pattern\nthrough the dynamic pricing policy applied by the smart grid operator. The\nplayers are guided to select the best strategy that consists of scheduling\ntheir electric appliances in order to minimize the daily energy cost and their\ndiscomfort level. The Nash Equilibrium of the energy management game is\nachieved using Non-Sorting Genetic Algorithm NSGA-II. Simulation results show\nthe effectiveness of the distributed non cooperative game approach for the\nresidential energy management problem where an appreciable energy cost\nreduction is reached while maintaining the discomfort in an acceptable level.\n
Criteria of quantum correlation in the measurement of continuous variables in optics (2004)

The purpose of this short tutorial paper is to review various criteria that have been used to characterize the quantum character of correlations in optical systems, such as "gemellity", QND correlation, intrication, EPR correlation and Bell correlation, to discuss and compare them. This discussion, restricted to the case of measurements of continuous optical variables, includes also an extension of known criteria for "twin beams" to the case of imbalanced correlations.
Stick-slip behavior in a continuum-granular experiment (2015)

We report moment distribution results from a laboratory experiment, similar in character to an isolated strike-slip earthquake fault, consisting of sheared elastic plates separated by a narrow gap filled with a two-dimensional granular medium. Local measurement of strain displacements of the plates at 203 spatial points located adjacent to the gap allows direct determination of the event moments and their spatial and temporal distributions. We show that events consist of spatially coherent, larger motions and spatially extended (noncoherent), smaller events. The noncoherent events have a probability distribution of event moment consistent with an M(-3/2) power law scaling with Poisson-distributed recurrence times. Coherent events have a log-normal moment distribution and mean temporal recurrence. As the applied normal pressure increases, there are more coherent events and their log-normal distribution broadens and shifts to larger average moment.
Birdshot retinochoroidopathy (1999)

Birdshot retinochoroidopathy is a rare, chronic, bilateral, posterior uveitis with a distinctive clinical presentation and a strong genetic association. 2] his review provides an updated summary of the current state of knowledge about birdshot retinochoroidopathy. It includes results of visual field and electrophysiological testing from markedly more patients than previous reports of these data. Furthermore, it provides prognostic information regarding visual acuity based on nearly twice the number of patients than the one previous report of this aspect of the disease. Such information is of special interest to patients. The paper is based on a chart review of the 59 birdshot patients evaluated at the National Eye Institute (NEI) and from a comprehensive review of the literature.
Multigrid analysis of scattering by large planar structures (2002)

Abstract Fast iterative analysis of two‐dimensional scattering by a large but finite array of perfectly conducting strips requires efficient evaluation of the electric field. We present a novel multigrid algorithm that carries out this task in CN computer operations, where C depends logarithmically on the desired accuracy in the field, and N is the number of spatial grid points. Numerical results are presented, and extensions of the algorithm are discussed. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 32: 454–458, 2002.
Engineering Tunnel Barriers in Hybrid Silicon/Molecular Memory Devices (2006)

This paper discusses the role of asymmetric tunneling across oxide barriers in Hybrid Silicon/Molecular devices. Devices incorporating redox-active (ferrocene) molecules on silicon dioxide (SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ) of varying thickness and Hafnium dioxide (HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> )/SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> stack on p-Si substrates were investigated as charge storage elements. The reduction (erase) process was found to be increasingly rate-limited as compared to oxidation (write) process with increasing SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> thickness. This is attributed to asymmetric tunneling rates mainly due to a lower potential drop across the tunnel barrier for a given gate voltage during reduction process as compared to oxidation, resulting from higher surface potential drop in Si. Although increased SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> thickness provides for improved retention, it severely retards write process. This can be overcome by employing asymmetric layered barrier of HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> /SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> which enhances effect of inherent asymmetric tunneling rates and also speeds up the write process due to higher relative permittivity and lower barrier offsets of HfO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> /SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> on Si as compared to SiO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . This behavior can be utilized to improve retention properties of these hybrid memory devices with minimal deterioration in write times.
