A millimeter-wave tunneladder TWT (1988)

A millimeter-wave traveling wave tube (TWT) was developed using a dispersive, high-impedance forward wave interaction structure based on a ladder, with non-space-harmonic interaction, for a tube with high gain per inch and high efficiency. The 'TunneLadder' interaction structure combines ladder properties modified to accommodate Pierce gun beam optics in a radially magnetized PM focusing structure. The development involved the fabrication of chemically milled, shaped ladders diffusion brazed to diamond cubes which are in turn active diffusion brazed to each ridge of a doubly ridged waveguide. Cold-test data, representing the (omega)(beta) and and impedance characteristics of the modified ladder circuit, were used in small and large-signal computer programs to predict TWT gain and efficiency. The structural design emphasizes ruggedness and reliability. Actual data from tested tubes verify the predicted performance while providing broader bandwidth than expected.
Waveguiding in InGaN/GaN/AlGaN blue laser structures (2005)

Symmetric InGaN/GaN/AlGaN conventional blue laser waveguides are analyzed. It is shown that due to the limited thickness of the confinement layers, the confinement factor in the active region and the modal absorption are considerably influenced by the substrate and GaN buffer layers. These phenomena are due to the coupling of the light outside of the active region in the substrate and buffer layers and show resonances with respect to the thickness of the buffer layer. These effects may strongly affect the gain, the near-field and the far-field of the lasing mode, specially if the substrate is SiC or GaN. In order to optimize the laser waveguide an alternative structure is proposed with a few microns thick AlGaN buffer layer instead of the usual GaN buffer layer. We also propose to use asymmetric structures where the extension of the optical field is minimized in the p-side and extended in the n-regions.
Defect in human myocardial long-chain fatty acid uptake is caused by FAT/CD36 mutations (2001)

Because of the importance of long-chain fatty acids (LCFAs) as a myocardial energy substrate, myocardial LCFA metabolism has been of particular interest for the understanding of cardiac pathophysiology. Recently, by using radiolabeled LCFA analogues, myocardial LCFA metabolism has been clinically evaluated, which revealed a total defect of myocardial LCFA accumulation in a small number of subjects. The mechanism for the cellular LCFA uptake process is still disputable, but recent results suggest that fatty acid translocase (FAT)/CD36 is a transporter in the heart. In the present study, we analyzed mutations and protein expression of the FAT/CD36 gene in 47 patients who showed total lack of the accumulation of a radiolabeled LCFA analogue in the heart. All the patients carried two mutations in the FAT/CD36 gene, and expression of the FAT/CD36 protein was not detected on either platelet or monocyte membranes. Our results showed the link between mutations of the FAT/CD36 gene and a defect in the accumulation of LCFAs in the human heart.
Synthesis and characterization of free-isocyanate polyurethane as renewable coating materials (2016)

Green synthesis of diethyl ethane-1,2-diyldicarbamate (M1) as starting dimer of free-isocyanate polyurethane from an excess of diethyl carbonate and ethylene diamine catalyzed by TBD (1,5,7-triazabicyclo-[4,4,0]dec-5-ene) at 80 °C for 4 hours has been carried out. The product has high yield and purity up to 92% and 99,18%, respectively. The product was obtained in the form of rod-shaped white crystals and characterized with 1H-NMR, 13C-NMR and FTIR spectroscopy. Polyurethane (P1) has successfully synthesized via polycondensation methods by reacting of M1 with cis-2-butene-1,4-diol. This reaction also catalyzed by TBD organo catalyst. P1 chemical structure has been confirmed using 1H-NMR and FTIR techniques.
Processor Controller for the IBM 3081 (1982)

The IBM 3081 represents an important step in the evolution of large-scale data processing systems. The incorporation of LSI technology in its design has resulted in a departure from the use of traditional support tools and techniques. Its increased processing capabilities and its dyadic organization have further accented the requirements for high availability and ease of operation. This paper describes the Processor Controller unit of the 3081 Processor Complex, which handles the functions of maintenance, monitoring, and control of the system. It discusses how this unit has dealt with these changes to keep pace with the demands of advanced technology and improved system availability. In providing the necessary test and support functions of reset and manual control, the Processor Controller exploits the level-sensitive scan design capability of the 3081 to obtain read/write access to all latches and arrays. This design approach, coupled with significantly expanded capabilities for error recovery, configuration control, and diagnostics, has significantly affected the structure and capabilities of the Processor Controller.
Fe<sub>3</sub>O<sub>4</sub>@ZIF-8: magnetically recoverable catalysts by loading Fe<sub>3</sub>O<sub>4</sub> nanoparticles inside a zinc imidazolate framework (2015)

A simple methodology for encapsulating ca. 10 nm-sized superparamagnetic Fe3O4 nanoparticles in zeolitic imidazolate frameworks (ZIF-8) crystals was developed. The corresponding Fe3O4@ZIF-8 heterostructured material exhibits bifunctional properties with both high magnetization (Fe3O4) and high thermal stability, large specific surface, and catalytic properties (ZIF-8). The Fe3O4@ZIF-8 catalyst exhibits fair separation ability and reusability, which can be repeatedly applied for Knoevenagel condensations and Huisgen cycloadditions for at least ten successive cycles.

Human Immunodeficiency Virus Infection in the US Air Force: Seroconversions, Clinical Staging, and Assessment of a T Helper Cell Functional Assay to Predict Change in CD4+ T Cell Counts (1991)

As of January 1990, 933 persons with human immunodeficiency virus type 1 (HIV-1) infection were clinically evaluated at Wilford Hall US Air Force (USAF) Medical Center. The Walter Reed HIV staging system was used in these evaluations to describe disease status and progression. Most persons were diagnosed through mandatory HIV testing in the USAF and were asymptomatic at the time of diagnosis. As of May 1990, 161 HIV-positive seroconverters (estimated overall seroconversion rate of 0.156/1000 person-years between 30 June 1988 and 1 July 1990) had been identified among active-duty USAF personnel, as they had previously tested negative for antibody to HIV. Men constitute 95% of the USAF HIV-positive population. An in vitro T helper cell functional assay was assessed to predict rate of CD4+ T cell decline over the subsequent year (mean, 15 months) in patients with greater than 200 CD4+ T cells/mm3. This assay may prove useful for prognostication and comparisons of patients in clinical trials of anti-HIV interventions.
A Real-Time Game Theoretic Planner for Autonomous Two-Player Drone Racing (2018)

In this article, we propose an online 3-D planning algorithm for a drone to race competitively against a single adversary drone. The algorithm computes an approximation of the Nash equilibrium in the joint space of trajectories of the two drones at each time step, and proceeds in a receding horizon fashion. The algorithm uses a novel sensitivity term, within an iterative best response computational scheme, to approximate the amount by which the adversary will yield to the ego drone to avoid a collision. This leads to racing trajectories that are more competitive than without the sensitivity term. We prove that the fixed point of this sensitivity enhanced iterative best response satisfies the first-order optimality conditions of a Nash equilibrium. We present results of a simulation study of races with 2-D and 3-D race courses, showing that our game theoretic planner significantly outperforms a model predictive control (MPC) racing algorithm. We also present results of multiple drone racing experiments on a 3-D track in which drones sense each others' relative position with onboard vision. The proposed game theoretic planner again outperforms the MPC opponent in these experiments where drones reach speeds up to 1.25 m/s.
Furan Derivatives. II. The Cyclization of 3-(Benzofuran-3-yl)propionic Acid Derivatives (1976)

Abstract A compound, 6-methoxy-2a,3,4,5-tetrahydro-2H-naphtho[1,8-bc]furan-5-one (XX), was prepared in a 72% yield by heating 3-(5-methoxy-2,3-dihydrobenzofuran-3-yl)propionic acid (XIX) with polyphosphoric acid. However, when 3-(5-methoxybenzofuran-3-yl)propionic acid (IX) or 3-(2-benzoyl-5-methoxybenzofuran-3-yl)propionic acid (XIII) were treated with polyphosphoric acid, the product was 7-methoxy-2,3-dihydro-1H-cyclopenta[b]benzofuran-3-one (XI) rather than the corresponding naphtho[1,8-bc]furan derivatives, Also, neither naphtho[1,8-bc]furan nor cyclopenta[b]benzofuran derivatives were obtained from 3-(2-benzyl-5-methoxybenzofuran-3-yl)propionic acid (XIV) or 3-(2-ethyl-5-methoxybenzofuran-3-yl)propionic acid (XVII).
Prevention of Carotid Artery Thrombosis by Oral Platelet GPIIb/IIIa Antagonist in Dogs (1997)

Platelet GPIIb/IIIa blockade with an orally active antagonist was shown to be safe and effective in the prevention of carotid artery occlusive thrombosis.
Optical Limiters, Switches, And Filters Based On Polymer Dispersed Liquid Crystals (1989)

We present results of our recent research in the implementation of optical modulation devices utilizing polymer dispersed liquid crystal materials. Optical bistability, power limiting, self-pulsations, and optical deflection (diffraction) have been observed in these devices. Experimental results and potential applications are discussed.
Defect chemistry of the cage compound, Ca12Al14O33−δ—understanding the route from a solid electrolyte to a semiconductor and electride (2009)

A crystallographic cage structure endows mayenite (Ca(12)Al(14)O(33) or 12CaO.7Al(2)O(3); C(12)A(7)) with remarkable properties, making it either an oxygen solid electrolyte or an inorganic electride upon reduction. In order to better understand the transport properties of C(12)A(7), we measured the equilibrium total conductivity as well as the electronic partial conductivity of single crystal mayenite as functions of activity of oxygen or water vapor at different temperatures in the range 1073 < or =T/K < or = 1273. A point defect model based on the assumption that the framework [Ca(12)Al(14)O(32)](2+) acts as a pseudo-donor describes well the isothermal conductivity vs. oxygen activity, enabling us to deconvolute the ionic and electronic partial conductivities. The ionic transference number evaluated therefrom clearly demonstrates how C(12)A(7) is converted from a solid electrolyte to an electride depending on the oxygen content. In addition, besides the well known degradation of ionic conductivity by water uptake, a short-term increase of conductivity upon abrupt hydration was recognized and interpreted as due to the transient increase in the concentration of oxygen interstitial along with proton in the initial stage of hydration. For the fully hydrated C(12)A(7), the conductivity relaxation curves upon switching of oxygen activity in a fixed water vapor pressure appear non-monotonic showing the extrema only in the plateau conductivity regime. A defect structure based hypothesis is proposed to explain the 2-fold re-equilibration kinetics.
Rotafolia songziensis gen. et comb. nov., a sphenopsid from the Late Devonian of Hubei, China (2005)

A sphenopsid from the Upper Devonian (Famennian) Xiejingsi Formation, south-western Hubei Province, China, previously named as various species in Sphenophyllum, Hamatophyton, Bowmanites and Sphenophyllostachys, is now reinvestigated and assigned to a new taxon, Rotafolia songziensis gen. et comb. nov. Its ribbed axes are anisotomous and possess slightly expanded nodes. Lateral axes are inserted at nodes on main axes. Whorls of much divided vegetative leaves are attached at nearly right angles to nodes of basal axes, and at acute angles to nodes of terminal axes. There are six leaves per whorl. The terminal strobilus includes a central axis and verticils of fertile units. Each fertile unit consists of a bract and numerous sporangia. The margin of the elongate-cuneate bract bears a distal and many lateral elongate segments. Clusters of elongate sporangia are abaxially attached to the base of the bract at the same level. The axis has an actinostele, composed of a three-ribbed, exarch primary xylem and radial secondary xylem. Although Rotafolia songziensis closely resembles Hamatophyton verticillatum in axis character, leaf morphology and primary xylem type, they are quite different in strobilar structure. Taxonomically, Rotafolia is placed in the order Sphenophyllales by three well-defined characters: 1) whorled appendages; 2) ribbed protosteles; 3) exarch primary xylem maturation.
Synthesis of Diindeno-Fused 4<i>H</i>-Cyclopenta[<i>def</i>]phenanthren-4-ones and Related Compounds via Benzannulated Enediynyl Propargylic Alcohols (2005)

[reaction: see text] Treatment of propargylic diols 5-7 with thionyl chloride promoted a cascade sequence of reactions leading to dichlorides 10-12 and, after reduction with tributyltin hydride, the diindeno-fused 4H-cyclopenta[def]phenanthrenes 13-15 in a single operation. Hydrolysis of 13 and 14 furnished 4H-cyclopenta[def]phenanthren-4-ones 16 and 17, respectively. Air oxidation of an alkaline solution of dichloride 11 produced diketone 18.
A hybrid dielectrophoretic and hydrophoretic microchip for particle sorting using integrated prefocusing and sorting steps (2014)

This work explores dielectrophoresis (DEP)-active hydrophoresis in sorting particles and cells. The device consists of prefocusing region and sorting region with great potential to be integrated into advanced lab-on-a-chip bioanalysis devices. Particles or cells can be focused in the prefocusing region and then sorted in the sorting region. The DEP-active hydrophoretic sorting is not only based on size but also on dielectric properties of the particles or cells of interest without any labelling. A mixture of 3 and 10 μm particles were sorted and collected from corresponding outlets with high separation efficiency. According to the different dielectric properties of viable and nonviable Chinese Hamster Ovary (CHO) cells at the medium conductivity of 0.03 S/m, the viable CHO cells were focused well and sorted from cell sample with a high purity.
Packaging system for high performance computer (2003)

A novel micropackaging system that meets the requirements of increased packaging and heat density is described. The use of bare LSI gate arrays allows the realization of gate densities of up to 4000 gate functions per 1 cm/sup 2/. New wiring technologies allow these ICs to be wired as a dense configuration. High packaging densities result in high power dissipation. High-efficiency cooling is therefore used, with heat being transferred directly to the cooling medium. The micropackaging system allows the main unit of the mainframe to be designed as a planar system. Up to nine multichip modules (MCMs) can be plugged into a micropackaging board (MPB). A planar module connector with a total of 1850 contact springs is mounted on one side of the MCM, and the other side has an integrated heat sink for transferring the power dissipated to the water-cooled cold plate (CP) of the main unit. This cold plate, which removes the heat generated by an entire unit, is rigidly mounted to the frame of the cabinet. On the module-mounting side of the MPB decoupling capacitors are placed close to the modules. An aluminum frame on the same side assures the uniform distribution of the 0 V potential, mechanically reinforces the main unit, and accommodates modules and tools.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Assembly and demonstration of high bandwidth-density optical MCM (2015)

Optical interconnect technology with a higher bandwidth density is required as the performance of high-end computer systems increases. In the previous version of our developed organic optical multi-chip modules, the size of the fiber connectors limited the density. To obtain a higher bandwidth-density, we developed compact waveguide - fiber connectors which couple waveguides with fibers in a direction perpendicular to the module surface. An assembly method of the organic optical multi-chip module is established, and over 30 Gb/s operation for all channels of optical transmitters and receivers is demonstrated.
Fracture toughness and strength of 96% alumina (1997)

There exists a need to understand the controlling factors that simultaneously impact strength and toughness in 96% alumina. The enhancement of both strength and toughness enables designers to extend the use limits and reliability for structural ceramics. This article presents mechanical property results from a group study examining the use of different alkaline-earth aluminosilicate intergranular compositions containing magnesium, calcium and strontium oxides (RO) in 96% alumina. Principal results address trends in indentation strength toughness and modulus of rupture. Trends in the data are presented relative to existing theories of thermal expansion mismatch toughening, grain-bridging crack-wake effect and crack deflection mechanisms. Strength is addressed in terms of strength after indentation, crack growth of indentation flaws and Weibull characterization for the strength distribution.
Afterload mold therapy: a new look at a time honored concept. (1980)

Afterloading techniques, low energy radium substitutes, and computer assisted dosimetry can be adapted to surface applicator mold therapy. This permits high total dose, low dose rate radiotherapy to be applied to sharply delimited volumes, while restricting exposure of involved personnel.
Indium-111 monoclonal antibody b72.3 scintigraphy in colorectal cancer correlation with computed tomography, surgery, histopathology, immunohistology, and human immune response (1992)

As part of an open-labeled nonrandomized multi-institutional Phase III study, the authors compared the results of In-111 (In-111) B72.3 glycyl-tyrosyl-n-diethylenetriaminepentaacetic acid lysine (GYK-DTPA) monoclonal antibody scintigraphy with computed tomography (CT), surgery, histopathology, immunohistology, and human antibody response in 23 patients with primary colorectal carcinoma. There were no significant adverse reactions to 1 mg of In-111-labeled antibody. Planar imaging identified 16 of 23 primary colon lesions, whereas single photon emission computer tomography (SPECT) imaging identified 21. SPECT also correctly identified lymphatic involvement in four patients. (There were two false-positive results.) Liver metastases were identified with SPECT imaging. Twenty-six percent of patients developed human anti-mouse antibody (HAMA). These preliminary results demonstrate that In-111 B72.3 GYK-DTPA is a safe monoclonal antibody conjugate that has a high sensitivity for identifying primary colorectal cancer. Regional lymphatic and distant liver metastases also can be imaged, but false-positive results can occur.
Use and Abuse of Appetite-Suppressant Drugs in the Treatment of Obesity (1993)

Most of the available appetite-suppressant drugs act on noradrenergic and possibly dopaminergic receptors to produce satiety. A smaller number increase excess neuronal serotonin levels by blocking serotonin reuptake or by increasing its release. All these drugs produce significantly greater weight loss than does placebo in most studies. Abuse is a problem with amphetamine, methamphetamine, and benzphetamine, whereas other drugs have minimal or no potential for abuse. Weight loss can be sustained for up to 36 months. Net weight loss, compared with placebo, ranges from 2 to 10 kg, and weight regain after terminating drug treatment proves that drugs do not work when not taken. The stigma of obesity, the public opprobrium toward obese persons, and regulatory rigidity have led to unjustified distrust in the potential of drug treatment for obesity.
Effect of Blade Torsion on Modeling Results for the Small Wind Research Turbine (SWRT) (2006)

The small wind research turbine (SWRT) testing project was initiated with the goal of better characterizing both small wind turbine loads and dynamic behavior. The main purpose of the testing was to produce high quality data sets for model development and validation and to help the wind industry further their understanding of small wind turbine behavior, including furling. Previous papers have discussed modeling results for the SWRT using the FAST aeroelastic simulator. This paper summarizes modeling results from both the FAST and ADAMS aeroelastic simulators. The ADAMS model allows for blade torsional stiffness to be modeled, which is shown to significantly improve the agreement between model and test results for rotor speed and explain variances in previous comparisons between the SWRT FAST modeling results and the SWRT test data. The ADAMS model results also show that the aerodynamic pitching moment impacts the blade torsion more than the inertial forces.
The Epstein-Barr virus (EBV) small RNA EBER1 binds and relocalizes ribosomal protein L22 in EBV-infected human B lymphocytes. (1994)

Epstein-Barr virus (EBV), an oncogenic herpesvirus, encodes two small RNAs (EBERs) that are expressed at high levels during latent transformation of human B lymphocytes. Here we report that a 15-kDa cellular protein called EAP (for EBER associated protein), previously shown to bind EBER1, is in fact the ribosomal protein L22. Approximately half of the L22 in EBV-positive cells is contained within the EBER1 ribonucleoprotein (RNP) particle, whereas the other half residues in monoribosomes and polysomes. Immunofluorescence with anti-L22 antibodies demonstrates that L22 is localized in the cytoplasm and the nucleoli of uninfected human cells, as expected, whereas EBV-positive lymphocytes also show strong nucleoplasmic staining. In situ hybridization indicates that the EBER RNPs are predominantly nucleoplasmic, suggesting that L22 relocalization correlates with binding to EBER1 in vivo. Since incubation of uninfected cell extracts with excess EBER1 RNA does not remove L22 from preexisting ribosomes, in vivo binding of L22 by EBER1 may precede ribosome assembly. The gene encoding L22 has recently been identified as the target of a chromosomal translocation in certain patients with leukemia, suggesting that L22 levels may be a determinant in cell transformation.
