Comparison of the effects of Ficoll-Hypaque separation and whole blood lysis on results of immunophenotypic analysis of blood and bone marrow samples from patients with hematologic malignancies (1995)

We compared flow cytometric immunophenotyping results obtained by using the lysed whole blood method of sample preparation with those obtained by using Ficoll-Hypaque-separated cells on 44 consecutive specimens from patients with various hematologic malignancies. When the samples were analyzed as a group, seven antigens (CD2, CD3, CD5, CD11c, CD20, CD22, and CD34) demonstrated significantly different percentages of positively staining cells. When the samples were grouped by disease, results for patients with acute lymphocytic leukemia were discordant for CD22 and HLA-DR and results for patients with hairy cell leukemia were discordant for CD34. Most of the differences, however, were not with antigens critical to the evaluation of the malignancy. Additionally, the most frequent reason for differences in the percentage of positive cells was due to isotype control-based placement of the quadrant markers and not an actual discrepancy in staining. However, analysis of the CD34 antigen yielded eight instances in which staining of Ficoll-Hypaque-separated cells was essentially negative, but a clearly positive population was evident with the lysed preparation. This finding has important implications because of the prognostic significance of this antigen. Further studies are needed to determine the cause of this phenomenon.

40.2: Application of Organic Electroluminescent Device to Color Print Head (2000)

Abstract Organic electroluminescent (EL) devices were applied to the print head for portable color printers. Using the organic EL print head (ELPH) with an optimized structure as the light source, high quality full color prints were obtained by directly exposing image data onto instant color films. The test sample of ELPH used Alq 3 for the emission layer. Each emission color was attained through color filters of R, G and B. The ELPH is quite effective for realizing a portable color printer featuring high display quality, high‐speed printing and low power consumption.
TRANSFORMATION OF RANDOM BREAKING WAVES ON SURF BEAT (1986)

Based on a previous study by the authors of regular breaking waves in the surf zone, a model for random wave transformation across the nearshore region is developed. The results of a laboratory investigation of the effect of a steady opposing current on the wave decay process are presented and a proposed governing equation verified. Surf beat effects on wave transformation are then included in the model by representing the long wave as a temporally and spatially-varying current and mean water level. The concept of an equivalent water depth, which contains the effect of the current, is introduced and then included in a stochastic form in the random wave model. Surf beat is found to noticeably increase the decay of the root mean square wave height, especially in the inner surf where the beat is strongest. Comparison of the models to two field data sets show very good agreement for Hotta and Mizuguchi (1980), but rather poor for Thornton and Guza (1983). Possible explanations for the unexpected behavior of the second data set, pertaining to filtering, are discussed. Finally, a possible explanation for the dependence of random wave decay on deepwater steepness, noted by Battjes and Stive (1985), is presented.
In vitro induction of IgM secretion and switching to IgG production in human B leukemic cells with the help of T cells. (1980)

In vitro stimulation of the B leukemic cells (B-CLL cells) with normal allogeneic T cells plus PWM induced IgM secretion and a switching from IgM to IgG production. Induction of IgM and IgG production in B-CLL cells with T cells was demonstrated by the presence of the same idiotype in induced Ig as that present in the monoclonal IgM protein in the patient's serum. Both T cells and PWM were required for Ig induction in B-CLL cells, and x-irradiated T cells showed the comparable helper effect. T cells and PWM induced not only Ig secretion but proliferation of B-CLL cells. Cell division was essential for the differentiation of the leukemic cells to Ig-producing cells. PWM-induced, antigen-nonspecific helper factor(s) were also effective in the induction of differentiation of the leukemic cells. Variations existed among T cell donors in the capabilities to induce differentiation of the same leukemic cells, suggesting the requirement of matching of acceptors on B-CLL cells and T effector molecules for the induction of Ig production in B-CLL cells.
The Application of Mitsunobu Cyclization for the Synthesis of 2′,3′-Dideoxy-C-Nucleosides Designed as Didanosine Analogues (2009)

The synthesis of new 2′,3′-dideoxy-C-nucleosides structurally related to didanosine has been achieved. Their preparation involved condensation of a suitably substituted, lithiated 2- or 4-picoline with 2′,3′-dideoxy-5′-benzylribonolactone, followed by borohydride reduction of the resulting hemiacetals, intramolecular Mitsunobu cyclization of the derived diols, formation of the pyrazolo[3,4-c] or [4,3-b]pyridine ring-system and subsequent removal of the protecting groups.
Reaction Conversion for a Plasma-Based Steady-State Flow Process Is Independent of Reactor Volume (2018)

Electrical discharges in gases or plasmas allow dissociation and conversion of molecular precursors, such as methane, at relatively low temperature. In a steady-state reactor geometry, the reaction conversion has been suggested to be dependent on basic process parameters, such as residence time, which, in turn, is a function of reactor volume and gas flow rate, and power. Here, we show, through a combined experimental and modeling study, that, for a plasma-based steady-state reactor, conversion is dependent on gas flow rate and power, but essentially independent of volume. A critical part of the experiments was to confine the plasma volume so that the power and volume could be controlled separately, and a critical part of the modeling was to segment the reactor into a volume containing filamentary discharges and a volume containing an afterglow to capture the spatial heterogeneity of our dielectric barrier discharge. The resulting similarity law for the conversion is consistent with the idea of energy density for a plasma process, but shows how such a reaction scheme is distinct from other chemical approaches.
Precise time synchronization on a high available redundant ring protocol (2009)

This paper presents the different tradeoff in implementing IEEE1588 on top of HSR by evaluating the different alternatives offered by the time synchronization protocol. The evaluation is based on the accuracy of the achieved synchronization, its complexity and its conformance to the HSR protocol. While HSR and IEEE1588 seem to be promising candidates for substation automation communications, their simultaneous usage raises interesting challenges as they are based on opposite assumption.
Sensorless control of permanent magnet synchronous motor using matrix converters (2005)

Space Modulation Profiling technique is used to furher improve the estimated angle. Experimental results demonstrate the remarkable performance of the sensorless speed control employing the Matrix Converter and the contributions of the Space Modulation Profiling technique.
Fear and Boundaries: Acting in the Shadow of Trauma (2019)

Returning to an academic setting to study acting after 12 years of working professionally has led me to a singular discovery: Trauma has impacted my life and my way of working so deeply that I could not see the forest for the trees. The role of the Mechanic in Will Enos Middletown presents the opportunity to challenge my habitual self-censorship. My entrenched fears of inadequacy and my lack of boundary setting have prevented me from finding depth and honesty in my work. I intend to use somatic practices including The Batdorf Technique and Fitzmaurice Voicework to attain a level of tolerance for the physical sensations that are associated with my trauma. Ive chosen the role of the Mechanic as it presents challenges that include physical violence and the depiction of addiction. I hope to transcend my past and move steadily forward as an artist and a wholly thriving human being.
<title>Hard x-ray microanalytical beam line at the CAMD synchrotron</title> (1995)

Argonne National Laboratory (ANL) is collaborating with Louisiana State University (LSU) in constructing a synchrotron x-ray micro-analytical beamline at the Center for Advanced Microstructures and Devices (CAMD) in Baton Rouge, Louisiana. This project grew from earlier work at the National Synchrotron Light Source (NSLS), where a team of ANL researchers developed techniques to examine small-scale structures in diffusion zones of a variety of materials. The ANL/CAMD beamline will use x-ray fluorescence, diffraction, and absorption spectroscopy techniques to reveal both compositional and structural information on a microscopic scale.
High radiance InGaAsP/InP lensed LEDs for optical communication systems at 1.2-1.3 µm (1981)

The fabrication of high radiance InGaAsP/InP double-heterostructure (DH) surface-emitting LED's at 1.27 μm wavelength has been described. The elimination of the junction misplacement as well as the optimization of the active layer thickness has been found to be important in realizing high quantum efficiency. An ideal DH, free from the junction misplacement, has been fabricated by using Cd as the dopant in the InP carrier confining layer. The active layer thickness for maximum output power has been determined to be <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1-1.5 \mu</tex> m. Furthermore, a new fabrication technique has been developed and the LED structure, which has a lens monolithically formed on the InP substrate, has been fabricated for the first time at this wavelength. This lensed LED improves the coupling efficiency greatly, 2.7 times that of the flat LED's. A maximum coupled power of approximately 0.20 and 0.31 mW has been attained at 100 mA for 85 μm core, 0.16 NA and 100 μm core, 0.25 NA step index fibers, respectively.
A 50-nm Gate-Length Metamorphic HEMT Technology Optimized for Cryogenic Ultra-Low-Noise Operation (2021)

This article reports on the investigation and optimization of cryogenic noise mechanisms in InGaAs metamorphic high-electron-mobility transistors (mHEMTs). HEMT technologies with a gate length of 100, 50, and 35 nm are characterized both under room temperature and cryogenic conditions. Furthermore, two additional technology variations with 50-nm gate length are investigated to decompose different noise mechanisms in HEMTs. Therefore, cryogenic extended Ku-band low-noise amplifiers of the investigated technologies are presented to benchmark their noise performance. Technology C with a 50-nm gate length exhibits an average effective noise temperature of 4.2 K between 8 and 18 GHz with a minimum of 3.3 K when the amplifier is cooled to 10 K. The amplifier provides an average gain of 39.4 dB at optimal noise bias. The improved noise performance has been achieved by optimization of the epitaxial structure of the 50-nm technology, which leads to low gate leakage currents and high gain at low drain current bias. To the best of the authors' knowledge, this is the first time that an average noise temperature of 4.2 K has been demonstrated in the Ku-band.

Widespread mangrove damage resulting from the 2017 Atlantic mega hurricane season (2020)

Abstract Comprised of 17 named tropical storms, 6 of which were major hurricanes, the 2017 Atlantic hurricane season ranked as one of the most damaging and costly hurricane seasons on record. In addition to socio-economic impacts, many previous studies have shown that important coastal ecosystems like mangroves are shaped by severe storms. However, little is known about how the cumulative effects of storms over entire hurricane seasons affect mangroves across large regions. We used satellite imagery from the entire Caribbean and Gulf of Mexico region to show that 2017 resulted in disproportionate mangrove damage compared to baseline responses over the previous 8 years. Specifically, we observed 30 times more mangrove damage, via a reduction in the normalized difference vegetation index (NDVI), during 2017 compared to any of the eight previous hurricane seasons, and most (72%) of this damage persisted throughout the 7 month post-hurricane season period as indicated by no NDVI recovery. Furthermore, wind speed, rainfall, and canopy height data showed that mangrove damage primarily resulted from high maximum wind speeds, but flooding (cumulative rainfall), previous storm history, and mangrove structure (canopy height) were also important predictors of damage. While mangroves are known to be resilient to hurricane impacts, our results suggest that increasingly frequent mega-hurricane seasons in the Caribbean region will dramatically alter mangrove disturbance dynamics.
Immunochemical analysis of human kidney reticulin. (1992)

This study characterized the nature of reticulin fibrils from human kidney cortex by immunochemical analysis. Controls consisted of type I collagen fibrils derived from the kidney parietal capsule. Most of the fibrils in the capsule ranged in diameter from 60 to 80 nm whereas reticulin fibrils from the cortex ranged from 30-45 nm. Immunochemistry by light and electron microscopic examinations was carried out with antibodies directed against type I and type III collagens, their corresponding aminopropeptides, and decorin (PG-II). The ratio of type I to type III collagen was determined by cyanogen bromide peptide digests. This study showed that reticulin fibrils are hybrids of type I and type III collagens. Double immunoelectron microscopic examination showed that fibrils 20-25 nm consisted mainly of type I collagen some of which retained their aminopropeptide. Larger fibrils 30-35 nm labeled simultaneously for type I and type III collagens. However, most fibrils with diameters between 40-55 nm labeled for type III collagen and its corresponding aminopropeptide. No decorin was detected at the surface of reticulin fibrils. Purified reticulin consisted of 82% type III and 18% type I collagen whereas collagen derived from the capsule revealed 76% type I and 24% type III. The presence of the aminopropeptide of type III procollagen in reticulin fibrils is a striking feature and may play a role in regulating their diameter.
Timing of Changes in Interstitial and Venous Blood Glucose Measured With a Continuous Subcutaneous Glucose Sensor (2003)

The objective of this study was to use a subcutaneous continuous glucose sensor to determine time differences in the dynamics of blood glucose and interstitial glucose. A total of 14 patients with type 1 diabetes each had two sensors (Medtronic/MiniMed CGMS) placed subcutaneously in the abdomen, acquiring data every 5 min. Blood glucose was sampled every 5 min for 8 h, and two liquid meals were given. A smoothing algorithm was applied to the blood glucose and interstitial glucose curves. The first derivatives of the glucose traces defined and quantified the timing of rises, peaks, falls, and nadirs. Altogether, 24 datasets were used for the analysis of time differences between interstitial and blood glucose and between sensors in each patient. Time differences between blood and interstitial glucose ranged from 4 to 10 min, with the interstitial glucose lagging behind blood glucose in 81% of cases (95% CIs 72.5 and 89.5%). The mean (+/-SD) difference between the two sensors in each patient was 6.7 +/- 5.1 min, representing random variation in sensor response. In conclusion, there is a time lag of interstitial glucose behind blood glucose, regardless of whether glycemia is rising or falling, but intersensor variability is considerable in this sensor system. Comparisons of interstitial and blood glucose kinetics must take statistical account of variability between sensors.
Relatively low temperature synthesis of hexagonal tungsten carbide films by N doping and its effect on the preferred orientation, phase transition, and mechanical properties (2009)

The authors deposited N-doped tungsten carbide thin films on Si(100) substrates at 500°C using direct-current reactive magnetron sputtering in a mixture of CH4∕N2∕Ar discharge and explored the effects of N doping on the preferred orientation, phase transition, and mechanical properties of the films by using x-ray diffraction, x-ray photoelectron spectroscopy, and nanoindentation measurements. They found that N doping significantly influenced the compressive stress, which led to a pronounced change in the preferred orientation, phase structure, and hardness for the tungsten carbide film. A phase transition from β-WC to α-WC occurred when N doping was in the range of 2.9 and 4.7at.%, meaning that α-WC can be obtained at relatively low temperature (500°C). To reveal the relationship between the stress and phase transition, as well as preferred orientation, the density-functional theory based on first principles was used to calculate the elastic constants and shear modulus for tungsten carbide with a structure of β-WC or α-WC. The calculated results showed that the preferred orientation depended on the competition between strain energy and surface energy, as well as the grains competitive growth, and the phase transition can be attributed to a decrease in the strain energy. The hardness of α-WC was harder than β-WC because the shear modulus for α-WC was larger than that of β-WC, whereas the bulk modulus for α-WC was almost equal to that of β-WC.
Variation of molecular weight distribution (MWD) and short chain branching distribution (SCBD) of ethylene/1-hexene copolymers produced with different in-situ supported metallocene catalysts (2000)

Copolymerization of ethylene and 1-hexene was carried out with different catalysts: homogeneous Et[Ind]2ZrCl2, Cp2HfCl2 and [(C5Me4)SiMe2N(tert-Bu)]TiCl2, the corresponding in-situ supported metallocenes, and combined in-situ supported metallocene catalysts (mixtures of Et[Ind]2ZrCl2 and Cp2HfCl2, and Et[Ind]2ZrCl2 and [(C5Me4)SiMe2N(tert-Bu)]TiCl2). Carbon-13 nuclear magnetic resonance spectroscopy (13C NMR), gel permeation chromatography (GPC) and crystallization analysis fractionation (CRYSTAF) studies showed that, compared to the corresponding homogeneous metallocenes, in-situ supported metallocenes produced polymers having different 1-hexene fractions, molecular weight distributions (MWD) and short chain branching distributions (SCBD). It was also demonstrated that polymers with broader MWD and SCBD can be produced by combining two different in-situ supported metallocenes.

Prediction of Eating Activity using Smartwatch (2021)

Eating activity understanding has been extensively studied for its importance in our lives. Due to the lack of proper dietary management, obesity has been increasing worldwide, which causes many diseases. In this regard, adequate diet management is crucial for having a healthier life. This study aims to develop a system that allows users to manage their diet easily. This research proposed a method that estimates eating activities. The main objective of this research is to use an eating manner (way of eating) to identify more accurately the eating activity by arm’s acceleration using a smartwatch. The acceleration data were collected using a smartwatch during different mealtime. A total of 12 features are extracted from this data. We have examined different classifiers’ performance. Among them, the Support Vector Machine (cubic SVM) classifier performed best among all. An evaluation of the system resulted in eating activities detected with the maximum accuracy of 76.4% and an average accuracy of 71.9% using 10-folds cross-validation.

Faculty Opinions recommendation of Neuronal correlates of goal-based motor selection in the prefrontal cortex. (2003)

Choosing an action that leads to a desired goal requires an understanding of the linkages between actions and their outcomes. We investigated neural mechanisms of such goal-based action selection. We trained monkeys on a task in which the relation between visual cues, action types, and reward conditions changed regularly, such that the monkeys selected their actions based on anticipated reward conditions. A significant number of neurons in the medial prefrontal cortex were activated, after cue presentation and before motor execution, only by particular action-reward combinations. This prefrontal activity is likely to underlie goal-based action selection. PMID: 12855813
