Langmuir-Type Expressions for In-Situ Co-Doping of C with B or P in Si 1–x Ge x Epitaxial Growth by Chemical Vapor Deposition (2021)

In-situ co-doping process of C with B or P in Si 1−x Ge x (100) epitaxial growth by chemical vapor deposition (CVD) is investigated using SiH 4 –GeH 4 –SiH 3 CH 3 –B 2 H 6 or PH 3 –H 2 mixture. The in-situ doping of only C is explained quantitatively by the Langmuir-type adsorption and reaction at Si-Si, Si-Ge or Ge-Ge pair sites on the (100) surface. For in-situ co-doping of C with B, it is concluded that SiH 4 , GeH 4 , SiH 3 CH 3 and B 2 H 6 molecules are adsorbed and react at the pair sites and react at the B-occupied sites where B 2 H 6 molecules have been adsorbed at the pair sites and additionally B 2 H 6 molecules react at the C-occupied sites where SiH 3 CH 3 molecules have been adsorbed at the pair sites. For in-situ co-doping of C with P, it is concluded that SiH 4 , GeH 4 , SiH 3 CH 3 and PH 3 molecules are adsorbed and react at the pair sites and only GeH 4 molecules decompose at the P-occupied sites where PH 3 molecules have been adsorbed self-limitedly on the (100) surface without the reactions at the C-occupied sites. From these results, Langmuir-type quantitative expressions of the experimental results are confirmed for in-situ co-doping of C with B or P in Si 1–x Ge x (100) epitaxial growth by CVD.
Influence of physicochemical properties of laser‐modified polystyrene on bovine serum albumin adsorption and rat C6 glioma cell behavior (2006)

Biomaterial surface modification is an efficient way of improving cell-material interactions. In this study, sub-micrometer laser-induced periodic surface structures (LIPSS) were produced on polystyrene by laser irradiation. FT-IR analysis confirmed that this treatment also led to surface oxidation and anisotropic orientation of the produced carbonyl groups. As a consequence, the surface energy of the laser-treated polystyrene was 1.45 times that of the untreated polystyrene, as measured by contact-angle goniometry. Protein adsorption and rat C6 glioma cell behavior on the two substrates were investigated, showing that the changed physicochemical properties of laser-modified polystyrene surface led to an increase in the quantity of adsorbed bovine serum albumin and significantly affected the behavior of rat C6 glioma cells. In the early stages of cell spreading, cells explored their microenvironment using filopodium as the main sensor. Moreover, cells actively aligned themselves along the direction of LIPSS gradually and cell attachment and proliferation were significantly enhanced.
Improvements in optical sorting of mold-damaged wheat (2006)

The current study describes the use of three forms of optical measurement of single wheat kernels for screening of Fusarium head blight for eventual incorporation in high-speed optical sorters. Our previous research has demonstrated a sorting efficiency of approximately 50 percent with existing high-speed equipment, but a much higher efficiency (~95%) when analytical spectrometers are used. The intention of the current work is to bridge this efficiency gap. Knowledge gained from analysis of the single kernel in-flight response will provide design criteria for improvement of high-speed optical sorters for recognition of mold-damaged wheat.
Local search in unstructured networks (2002)

We review a number of message-passing algorithms that can be used to search through power-law networks. Most of these algorithms are meant to be improvements for peer-to-peer file sharing systems, and some may also shed some light on how unstructured social networks with certain topologies might function relatively efficiently with local information. Like the networks that they are designed for, these algorithms are completely decentralized, and they exploit the power-law link distribution in the node degree. We demonstrate that some of these search algorithms can work well on real Gnutella networks, scale sub-linearly with the number of nodes, and may help reduce the network search traffic that tends to cripple such networks.
HapticAid (2017)

We developed HapticAid, which is a wearable haptic augmentation system. This system enhances the skin vibrations that occur during touch and provide them as haptic feedback on the wrist. We revised HapticAid to be wearable and mobile by using a mobile platform and installed a digital signal processing to control haptic feedback for haptic experiences. This paper describes the implementation of our system, design of digital signal processing the method of wearing our system for haptic experiences.
Range Finding by Using NRD Guide Pulse Radar Front-End at 60 GHz (2006)

An NRD guide pulse radar front-end was fabricated for level sensor applications at 60 GHz. Main emphases were placed on circuit configuration and digital signal processing of multi-reflection for short range detection. Typically, an oscillation power is divided by a junction circuit and is introduced into two parts. One is for transmitter, and the other is for LO wave to construct hetero-dyne detection in receiver and the frequency of the former is up-converted so as to be different from the frequency of the LO wave, and thus, an amplifier is installed in the transmitting side due to low power of the up-converted millimeter-wave. In this paper, we proposed a new circuit configuration, which consists of a Gunn oscillator with two output ports to eliminate a junction circuit, a direct pulse-modulator to obtain a high level transmitting power without an expensive millimeter-wave amplifier, and a filter-based down-converter with an up-converter as a local oscillator. Multi-reflection between the radar front-end and target was removed by introducing an FPGA-based digital signal processing including high-speed counting, memorizing, and averaging. Good range finding was performed because the error was less than 1 % for the distance from 2 m to 40 m
Solid‐Phase Enzyme Activity Assay Utilizing an Entrapped Fluorescence‐Signaling DNA Aptamer (2006)

Layered enzyme assays: The use of a layered sol-gel based material allows for spatial separation of coimmobilized enzyme and fluorescent aptamer reporter species. This provides a route for facile assaying of enzyme activity and inhibition in cases where the aptamer signals the presence of the enzyme substrate. This then results in accurate IC50 determinations.

Irradiation-Induced Cardiac Connexin-43 and miR-21 Responses Are Hampered by Treatment with Atorvastatin and Aspirin (2018)

Radiation of the chest during cancer therapy is deleterious to the heart, mostly due to oxidative stress and inflammation related injury. A single sub-lethal dose of irradiation has been shown to result in compensatory up-regulation of the myocardial connexin-43 (Cx43), activation of the protein kinase C (PKC) signaling along with the decline of microRNA (miR)-1 and an increase of miR-21 levels in the left ventricle (LV). We investigated whether drugs with antioxidant, anti-inflammatory or vasodilating properties, such as aspirin, atorvastatin, and sildenafil, may affect myocardial response in the LV and right ventricle (RV) following chest irradiation. Adult, male Wistar rats were subjected to a single sub-lethal dose of chest radiation at 25 Gy and treated with aspirin (3 mg/day), atorvastatin (0.25 mg/day), and sildenafil (0.3 mg/day) for six weeks. Cx43, PKCε and PKCδ proteins expression and levels of miR-1 as well as miR-21 were determined in the LV and RV. Results showed that the suppression of miR-1 was associated with an increase of total and phosphorylated forms of Cx43 as well as PKCε expression in the LV while having no effect in the RV post-irradiation as compared to the non-irradiated rats. Treatment with aspirin and atorvastatin prevented an increase in the expression of Cx43 and PKCε without change in the miR-1 levels. Furthermore, treatment with aspirin, atorvastatin, and sildenafil completely prevented an increase of miR-21 in the LV while having partial effect in the RV post irradiation. The increase in pro-apoptotic PKCδ was not affected by any of the used treatment. In conclusion, irradiation and drug-induced changes were less pronounced in the RV as compared to the LV. Treatment with aspirin and atorvastatin interfered with irradiation-induced compensatory changes in myocardial Cx43 protein and miR-21 by preventing their elevation, possibly via amelioration of oxidative stress and inflammation.
Investigation of dilatancy in block-structured geological medium on the base of movable cellular automaton method (2011)

The peculiarities of dilatancy processes in block-structured media that experience nonequiaxial compression under shear deformation are investigated using movable cellular automaton (MCA) method. For a characteristic of compression nonequiaxiality (also termed the degree of constraint) a dimensionless parameter – the lateral to normal pressure ratio in the deformation plane – used. The main objective of the work is to trace the sequence in which various dilatancy mechanisms are involved in deformation depending on the level of shear stress and degree of constraint. It is shown that in the block-structured medium an increase in the degree of constraint causes the dominating dilatation mechanism to change from slip of discontinuity surfaces to opening and expansion of pores. The dominating dilatancy mechanism changing because increasing the degree of constraint increases the threshold shear stress at which the slip is activated. Beginning with certain lateral pressures, the slip is impeded giving way to expansion of the pore space; however, the latter fails to provide so considerable volume change as the slip of contact surfaces does, and this decrease critical dilatation characteristics of the medium and, in particular, its dilatation coefficient and volume changing.
Removal and recovery of cobalt from aqueous solutions by adsorption using low cost lignocellulosic biomass—coir pith (2010)

The applicability of low-cost lignocellulosic biosorbent-coir pith, for removal of cobalt (II) from aqueous solutions using batch adsorption studies has been explored herein. Adsorption characteristics of coir pith were investigated systematically by varying the experimental parameters such as, solution pH, initial metal ion concentration, contact time, adsorbent dose and temperature. The studies revealed that optimum adsorption of cobalt onto coir pith occurred in the pH range of 4.0 - 7.0. Sorption kinetics of cobalt was found to be quite rapid under ambient conditions and the process followed second-order kinetics. The experimental data have been analyzed using non-linearized forms of Langmuir, Freundlich and Redlich-Peterson adsorption isotherms for mathematical description of the process. Desorption studies showed that the quantitative recovery of Co (II) from the spent coir pith was achieved by using 0.5 N HCl. The suitability of this adsorbent for real situation has been observed, when complete removal of cobalt from nuclear power plant coolant water was obtained. The present studies successfully demonstrated the use of coir pith as an efficient adsorbent material for removal of cobalt from aqueous solutions.
INTRAGRAFT INTERLEUKIN-4 mRNA EXPRESSION AFTER SHORT-TERM CD154 BLOCKADE MAY TRIGGER DELAYED DEVELOPMENT OF TRANSPLANT ARTERIOSCLEROSIS IN THE ABSENCE OF CD8+ T CELLS1 (2000)

Our data provide evidence that short-term CD154 blockade is insufficient to prevent transplant arteriosclerosis, even in combination with CD8+ T-cell depletion. Moreover, the increased expression of the Th2 cytokine interleukin-4 within the graft may be responsible for the development of transplant arteriosclerosis in the long term.
Broadband Achromatic Metalens in Mid‐Wavelength Infrared (2021)

Abstract Metasurface provides a powerful platform to correct the chromatic aberration of conventional lenses in a flexible, integratable, and ultra‐compact manner. Mid‐wavelength infrared has promised many exciting applications ranged from molecular fingerprint detection to low‐light‐level night vision. Developing broadband achromatic metalens in mid‐wavelength infrared becomes necessary to meet the increasingly urgent demands on high performance photonic devices. Here, we demonstrate the broadband achromatic metalenses from 3.5 to 5 µm with all‐silicon metasurfaces. Large phase dispersion control range is achieved to realize metalenses with both large numerical apertures and sample sizes while maintaining high focusing efficiency. The experimental results verify the diffraction‐limited achromatic focusing and imaging of the metalenses in mid‐wavelength infrared. Additionally, we also demonstrate the versatility by successfully implementing the generation of the broadband achromatic focusing optical vortex ( L = 2). This work represents a solid step toward practical implementation of metalens and may find applications in mid‐wavelength infrared imaging and detections.

The PHELIX pulsed power project: Bringing portable magnetic drive to proton radiography (2012)

The PHELIX pulsed power project will introduce magnetically driven hydrodynamics experiments to the Los Alamos National Laboratory's proton radiography facility (pRad). The Precision High Energy-density Liner Implosion eXperiment (PHELIX) has been commissioned at Los Alamos. A small footprint capacitor bank consisting of four parallel, air-insulated, single-stage, marx units (U ~ 300 kJ) is cable coupled to a toroidal, current step-up transformer to deliver multi-megampere current pulses (t <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">pulse</sub> ~10 μs) to cm size cylindrical loads. In a sequence of tests the performance of each component (capacitor bank and transformer) was evaluated and compared to a computer model. The transformer coupling was observed to be k ~ 0.93. A series of liner implosion experiments has been performed in which an aluminum liner (R ~3 cm, r = 0.8 mm, L = 3 cm) was accelerated to a velocity of ~ 1 km/s. The suite of machine diagnostics included linear Rogowski coils and Faraday rotation for current measurements. The experimental diagnostics include B-dot probes, multi-channel photon Doppler velocimetry (PDV), and single-frame, flash X-radiography to evaluate the performance of the high precision liner implosion. Currently, work is focused on integrating PHELIX into normal operations with the 800 MeV proton radiography facility at the Los Alamos Neutron Science Center (LANSCE), to enable high-resolution, high-frame-rate imaging of hydrodynamic experiments.
Enhancement of an Azimuthal Anchoring Energy in a Photo-alignment Layer by Stacking Planar Alignment Layer (2013)

We propose a method to enhance an azimuthal anchoring energy by stacking photo-alignment layer onto a planar alignment layer. The exposure of LPUV to the stacked alignment layers gave rise to the strong azimuthal anchoring energy. As a result, we achieved the fast response time characteristics in the FFS mode.
Alternatives for Measuring Endogenous Adrenocortical Activity in Asthmatics Treated with Inhaled Corticosteroids (2005)

We compared a 12-hour, hourly integrated plasma cortisol profile in asthmatics treated with a corticosteroids with a variety of modified methods based on less frequent blood sampling. Excellent agreement with the reference was observed for sampling at 10 p.m. and 8 a.m. (correlation coefficient of 0.97; 95 % confidence interval 0.97, 0.98); at 9 p.m. and 7 a.m. (r = 0. 95; 0. 94, 0.96); at 11 p.m. and 7 a.m. (r = 0.94; 0.93, 0.95); every 2 hours (r = 0. 96; 0.96, 0.97); and every 3 hours (r = 0. 91, 0.91, 0.93). The two-sample alternatives (10 p.m/8 a.m. and 9 p.m/7 a.m.) are accurate, as well as more convenient, economical, and practical.
Abstract 12357: Discordant Mechanisms in Hypertrophy and Heart Failure (2021)

Introduction: Patients with heart failure and a preserved ejection fraction (HFpEF) present heart function abnormalities that remain poorly understood. Defining proteomic signature of HF that is independent of left ventricular hypertrophy (LVH) should allow for stratification of its subtypes and potential mechanism that contributes to the disease. Hypothesis: We hypothesized that HFpEF proteomic signature would be comprised of the hypertrophy and contractile protein phenotype. Methods: Intraoperative left ventricular (LV) myocardial biopsies were obtained from patients (n=21) recruited to undergo coronary artery bypass grafting (CABG). Patients were categorized to: control non-hypertensive (n=9), LVH (n=5), and HFpEF (n=7). Myocardial tissue was subfractionated: cytoplasmic- (neutral pH), myofilament- (acidic pH), and membrane-enriched extract (SDS-soluble). Samples were assessed for protein quantity and Lys/Arg modifications using liquid chromatography mass spectrometry (LC-MS). Results: In HFpEF, 13% of the cardiac LV proteome changed compared to control heart, with a substantial proportion (77%) decreasing in quantity across all three cardiac fractions, while with LVH, 61% of the proteomic LV changes were increased. Although glycolysis and gluconeogenesis increased in both cardiopathies with respect to control, in HFpEF more subtly than in LVH. Modified proteome of the HFpEF was dominated by decreases in protein succinylation (e.g. ATP5L, THIM, IDHP, APOB, GSH1, KNTC1) and to a lesser degree in methylation (ROA3, HSP7C) or acetylation compared to control group. This general trend of down-regulation of succinylation can be attributed to depletion in the levels of succinyl-CoA, the cofactor of enzymatic Lys succinylation. Importantly, there was a striking discordant activation/inhibition of cell death and proliferation pathways between the HFpEF and LVH. Two major upstream regulator clusters linked the proteome changes in cell growth and proliferation to RICTOR and Myc that showed completely opposite trends in LVH and HFpEF groups. Conclusions: HFpEF has a unique proteome signature compared to LV hypertrophy profile which does not arise from sub-proteome involved in contraction but rather is involved in overall cell death.
ISOBUS compatible implements in the project AGRIX (2005)

Intelligent implement systems are needed to realise Precision Farming. The ISOBUS standard (ISO 11783) for agricultural machines provides standardized communication between a tractor and implements. Implementation of the standard, however, is not an easy task to perform. In the project AGRIX an ISOBUS compatible implementation has been developed for three implements: two combined drills and a sprayer. The paper describes the R&D process starting from specifications to prototypes and testing. It shows major modifications for implements were needed to implement ISOBUS. These are described. First test results are presented.
Characterization of influenza H1N1 Gag virus-like particles and extracellular vesicles co-produced in HEK-293SF (2019)

One of the concerns associated with the use of influenza virus-like particles (VLPs) as vaccine candidate or delivery system is their heterogeneous composition. Enveloped VLPs take up the host cell membrane at the budding site carrying out not only the viral antigenic proteins but also host proteins. In addition, the intrinsic nature of cells to produce membrane derived vesicles or extracellular vesicles (EVs), which have similar size to the VLPs, makes VLP purification process challenging. To further characterize these particles and identify proteins that are unique to each population, comparative proteomic analyses were completed to ultimately provide guidance for rational design of separation protocols. The VLPs were produced in suspension and serum free media by transient transfection of an inducible clone of a Human Embryonic Kidney (HEK-293SF) cells expressing HA and NA (H1N1/A/Puerto Rico/8/34), with a plasmid containing the gag gene of HIV-1 fused to GFP. EVs were produced independently from the non-transformed HEK-293SF cell line as a control for comparative studies. Both preparations were characterized for total nucleic acids and protein concentrations and extensively analyzed by nanoLC-MS/MS for their protein compositions. The proteomic analyses showed that aside from the recombinant VLP proteins, nucleolin was the most abundant host cell protein uniquely identified within VLPs (considering the MASCOT score value) while lactotransferrin and heat shock protein 90 were the most abundant proteins in EVs. Overall, this comparative study identifies potential target proteins as specific markers to guide VLP purification and discusses the biogenesis of enveloped particles released in HEK-293 cell suspension cultures emphasizing on the biological functions of host cell proteins identified.
Quality Assurance through Automated Monitoring and Concurrent Feedback Using a Computer-Based Medical Information System (1978)

A computer-based medical information system (COSTAR) has been used to support a quality assurance program where the data collection is an integral part of the patient care recording activity and, therefore, does not require a separate abstracting or encoding process. This program utilizes concurrent audit to detect deficiencies in patient care, and automatic rapid feedback to the responsible provider in time to allow the provider to correct the deficiency. This system has been demonstrated to improve follow-up of throat cultures, positive for Group A Beta hemolytic streptococcus. It is well accepted by the medical staff whose practice is being audited. Because the data are collected as part of the routine operation of COSTAR, the computer monitoring and feedback have only a small incremental cost.
Composition and Conductivity of Membranes Equilibrated with Solutions of Sulfuric Acid and Vanadyl Sulfate (2013)

The sulfuric acid, vanadyl (VO2+) and water equilibrium in Nafion membranes contacted by solutions containing these species is described. Of particular interest is the influence of composition on ionic transport behavior in membrane separators for an all-vanadium redox flow battery (VRFB). Ex-situ membrane conductivity measurements were conducted on Nafion 117 membranes equilibrated in electrolyte solutions of varying sulfuric acid and vanadyl ion concentrations. Electrolyte species imbibed in the membrane were analyzed by an experimental protocol including titration, ICP-OES and weight analysis. Sulfuric acid in the membrane can increase proton concentration but reduce proton mobility by reducing water content. In a mixed vanadyl/proton form Nafion, vanadyl has a mobility of 6.28 × 10−5 cm2·V−1·s−1, much lower than proton mobility of 8.79 × 10−4 cm2·V−1·s−1 in H+-form Nafion. The presence of vanadyl in Nafion can also decrease the proton mobility: . With equilibration in a practical electrolyte containing 5 mol·dm−3 total sulfate, Nafion's conductivity is decreased due to uptake of vanadyl ions.
The palliative management of fungating malignant wounds (1995)

A review of the current ‘state of the art’ in the management of fungating malignant wounds
