Acetobacterium, a New Genus of Hydrogen-Oxidizing, Carbon Dioxide-Reducing, Anaerobic Bacteria (1977)

A new genus of fastidiously anaerobic bacteria which produce a homoacetic fermentation is described. Cells are gram-positive, oval-shaped, short rods which are actively motile by means of one or two subterminal flagella. Hydrogen is oxidized, and carbon dioxide is reduced to acetic acid. Organic substrates which are fermented in a mineral medium include fructose, glucose, lactate, glycerate, and formate. Pantothenate is required as a growth factor. The deoxyribonucleic acid base composition of the type species is 39 mol% guanine plus cytosine. The name Acetobacterium is proposed for this new genus, which is tentatively placed in the family Propionibacteriaceae. The type species, Acetobacterium woodii sp. nov., is named in honor of Harland G. Wood. The type strain of A. woodii is WB1 (= ATCC 29683 and DSM 1030).
Endotoxin, interleukin-1, and tumor necrosis factor cause neutrophil-dependent microvascular leakage in postcapillary venules. (1992)

Acute inflammation is characterized mainly by the egress of neutrophils from postcapillary venules and by increased vascular permeability leading to the formation of edema. The microvascular site of increased vascular permeability in local acute inflammatory lesions was investigated after the injection of endotoxin (LPS), interleukin-1 (IL-1), and tumor necrosis factor (TNF) into the dermis overlying the cremasteric and rectus abdominis muscles of rats. LPS caused leakage of colloidal carbon peaking at 3 to 4 hours at the level of the postcapillary venules and capillary leak was variably observed at later time points. IL-1 and TNF also caused postcapillary venular leakage. IL-1 was as potent as LPS and more so than TNF. The microvascular leak caused by LPS, IL-1, and TNF was accompanied by the tissue accumulation of neutrophils, and was neutrophil-dependent because LPS, IL-1, and TNF did not cause vascular labelling in neutropenic rats.
Rapid prenatal diagnosis of aneuploidy from uncultured amniotic fluid cells using five‐colour fluorescence <i>in situ</i> hybridization (1994)

In this paper we describe the use of five-colour fluorescence in situ hybridization for prenatal diagnosis of aneuploidy using uncultured amniotic fluid cells. The analysis is based on ratio mixing of dual-labelled probes and digital imaging for the detection and visualization of five different probes specific for the five target chromosomes, 13, 18, 21, X, and Y. A retrospective blind analysis of 30 coded uncultured amniotic fluid samples correctly detected fetal sex and five trisomy 21 cases. Multicolour fluorescence in situ hybridization used in this way allows rapid and simultaneous detection of the most frequent aneuploidies.
Automatic Data Acquisition and Control of Experiments in a Powder X-Ray Diffractometer (1973)

The instrumentation of a powder x-ray diffractometer for automatic data acquisition and control of experiments is described. The present system configuration is set up to step-scan preselected intervals in the 2θ range, in preset stepping increments, while operating either in the fixed time or in the fixed count mode. The data can either be stored in punched paper tape and cards, or be transmitted to a computer. At the end of a complete 2θ-scan, one or more experimental parameters can automatically be changed, after which the whole scan is started again.

Design of an UHF RFID transponder for secure authentication (2007)

RFID technology increases rapidly its applicability in new areas of interest without guaranteeing security and privacy issues. This paper presents a new architecture of an RFID transponder with cryptographic capabilities. Other than being compatible with the EPC Class-1 Gen-2 communication protocol, our tag implements an asymmetric ciphering module that proved useful in authentication and anti-counterfeit schemes, particularly critical in many application fields. Experimental results concerning area requirements and power consumption indicate its feasibility.
Absorber Intercooling Configurations using Aqueous Piperazine for Capture from Sources with 4 to 27% CO2 (2014)

A systematic evaluation of the solvent capacity and mass transfer benefits of absorber intercooling was conducted for CO2 capture with 8 m piperazine (PZ) for three different flue gas sources: NGCC (4.1% CO2), coal-fired boiler (14.7% CO2), and steel blast furnace (27.4% CO2). The study identified the best intercooling strategy as a function of operating conditions (lean loading, liquid to gas ratio (L/G)). For all applications, operation at low lean loadings did not require intercooling to avoid temperature-related capacity or mass transfer penalties. In a broad intermediate loading range, simple in-and-out intercooling provided large solvent capacity benefits (measured as minimum solvent rate, LMIN) compared to a column without intercooling. LMIN was reduced by 71%, 53%, and 42% for NGCC, coal, and steel, respectively. Finally, the coal and steel applications had a large L/G range at higher loadings where intercooling was once again unnecessary. An enhanced intercooling design for NGCC could yield up to 62% reduction in packing and 46% reduction in solvent capacity at specific conditions (benefits for coal and steel were much lower). A recycle intercooling design for NGCC was introduced to reduce overall column temperatures and enhance mass transfer. For the case evaluated with recycle intercooling, the new design achieved significant packing reductions (>50%) compared to a simple intercooling design and approximated the performance of an isothermal column.
Nanopore formation induced by ion-implantation in Ge: optical properties (2014)

Self-ion implantation on bulk Ge induces the formation of nanopores,\nand their growth, structure and transport properties have been recently reported\n[1]. Semiconductors containing nanopores have gained a renewed interest as\nthey are able to adsorb and interact with atoms and molecules and can thus be\nused in several interesting and emerging applications. In this contribution we\nreport on the influence of ion implantation and subsequent nanopore formation\non optoelectronic properties of Ge samples. The analyses are carried out by\nSurface Photovoltage (SPV) Spectroscopy, a powerful technique to get detailed\ninformation on material optical properties [2]. Different nanoporous (np)\nstructures have been investigated: crystalline and amorphous np-Ge obtained\nby implantation of bulk Ge, as well as crystalline and amorphous np-Ge obtained\nby ion implantation of Ge film grown on Si substrates by molecular beam\nepitaxy and sputtering. Changes in the SPV spectra as a function of ion\nimplantation fluence and annealing treatments are discussed on the basis of the\nstructural properties of the samples. Quantum confinement effects in\nnanoporous Ge film have been demonstrated, while a significant SPV\nenhancement in np-Ge samples decorated with Au nanoparticles has been\nshown. These results can be of major interest for future photovoltaic\napplications of thin film solar cells. G Impellizzeri et al Nanotechn 23, 395604\n(2012) L Kronik and Y.

Hapten-reactive inducer T cells. I. Definition of two classes of hapten-specific inducer cells. (1983)

Hapten-reactive inducer T cell clones can be divided into two groups based on their activation specificity. The first and largest group is conjugate specific. These clones are activated only by hapten coupled to the same carrier protein used for in vitro selection. The second group, which is quite rare, is hapten specific. Clones of this type are activated by hapten coupled to all foreign and autologus proteins tested. Both types of clones corecognize soluble antigen in association with products of the I-A locus. The hapten-specific cells were used to analyze the molecular basis of I-A vs. I-E gene control. The physiologic significance of hapten- and carrier-specific inducer T cells in the response to foreign antigens and autoantigens is discussed.
Diffuse Cystic Lung Disease. Part II (2015)

Abstract The diffuse cystic lung diseases have a broad differential diagnosis. A wide variety of pathophysiological processes spanning the spectrum from airway obstruction to lung remodeling can lead to multifocal cyst development in the lung. Although lymphangioleiomyomatosis and pulmonary Langerhans cell histiocytosis are perhaps more frequently seen in the clinic, disorders such as Birt-Hogg-Dubé syndrome, lymphocytic interstitial pneumonia, follicular bronchiolitis, and light-chain deposition disease are increasingly being recognized. Obtaining an accurate diagnosis can be challenging, and management approaches are highly disease dependent. Unique imaging features, genetic tests, serum studies, and clinical features provide invaluable clues that help clinicians distinguish among the various etiologies, but biopsy is often required for definitive diagnosis. In part II of this review, we present an overview of the diffuse cystic lung diseases caused by lymphoproliferative disorders, genetic mutations, or aberrant lung development and provide an approach to aid in their diagnosis and management.
Measurements of priority pollutants in combustion products derived from the Dept. of Energy's (DOE) coal-fired flow facility magnetohydrodynamic (MHD) (1988)

Magnetohydrodynamics is a branch of the physical sciences dealing with the electromagnetic fields and electrically conduction gases and liquids. Examples of MHD are everywhere, from stars and nuclear fusion to applications like MHD electrical power generation, i.e. when electrical conductors cut magnetic field lines, an electromotive force (EMF) is induced. If electrodes and external circuits are connected, current will flow. In conventional electric generators, the copper wire conductors are rotated through a magnetic field, and are usually driven by a steam turbine. On the other hand, the conductor in an MHD system is a fluid (gas or liquid) which flows through a magnetic field. There are two basic types of MHD energy conversion systems - open cycle and closed cycle. In closed cycle, the working fluid or conducting medium is recycled, while in the open cycle it is appropriately utilized and discarded. In this paper, the authors discuss the priority pollutants study carried out for an open cycle concept in which the conductor is a high temperature combustion gas, which flows through a magnetic field from a high pressure source and is not recycled.
STATIC GENERATION AND CONTROL IN TEXTILE SYSTEMS C04-NS07 (2007)

This report reviews the progress on the research of static generation/dissipation properties of polymeric yarns and films. Three testing devices (linear tester, contact tester, and rubbing tester) have been developed to measure static generation on film and yarn surfaces. The devices are housed in a dedicated environmental room that can precisely control relative humidity and temperature. Polyester yarns’ static charge generation/dissipation properties were tested at different levels of tension and speed using the linear tester under controlled environment. Polymer films’ contact static properties were tested at different contact pressures, contact frequency using the contact tester. The static properties of these polymeric films were previously measured using the rubbing tester (see annual report 0f 2006).
Biophotolysis systems for hydrogen production (1981)

Model systems containing natural and synthetic catalysts were constructed for the production of H/sub 2/ from water using visible solar radiation as the energy source. The authors have investigated the use of aqueous systems with proflavine as the light activator and artificial electron donors for subsequent production of H/sub 2/ when coupled to electron mediators and hydrogenase (or Pt). The characteristics, relative merits and defects of these systems are discussed. 22 refs.

A square root of a matrix approach to obtain the solution to a steady-state matrix Riccati equation (1976)

By utilizing the square root of a matrix approach, a method of generating the solution to a steady-state matrix Riccati type equation (under certain restrictions) is presented. This approach not only yields a closed form expression for the Riccati solution, but also converts the original Riccati equation into other equations which may have numerical or computational advantages. An example is worked out for a second-order case.
Brachyolmia: Radiographic and genetic evidence of heterogeneity (1989)

Brachyolmia refers to a form of skeletal dysplasia characterized by general platyspondyly without significant epiphyseal, metaphyseal, or diaphyseal changes in the long bones. As a result of a study of 11 patients from 7 different families and a review of the literature we propose that there are 3 and possibly 4 different types of brachyolmia: 1. Hobaek type--an autosomal recessive condition with universal platyspondyly, irregular, and reduced intervertebral spaces and marked extension of the lateral margins of the vertebrae. Rectangular and elongated vertebral bodies are seen on lateral views of the spine, which become more pronounced with age. Toledo type--radiographically similar to Hobaek type but also associated with corneal opacities and precocious ossification of costal cartilage. It is uncertain as to whether this represents variability or heterogeneity. 2. Maroteaux type--an autosomal recessive disorder that is distinguished from Hobaek type by rounding of the anterior and posterior vertebral borders with less elongation on lateral view and less lateral extension on A.P. view. This type may be associated with precocious calcification of the falx cerebri, and minor facial anomalies. 3. Dominant type--a previously underscribed form which we have observed in a mother and her son. This type has the most severe vertebral changes with flattening and irregularities of the cervical spine. These clinical, radiological, and genetic differences suggest genetic heterogeneity in this group of platyspondylic disorders.

3-Miktoarm Star Terpolymers via Janus Polymerization: One-Step Synthesis and Self-Assembly (2018)

Janus polymerization combines cationic and anionic polymerizations into the two ends of a single growing chain and presents a novel pathway to produce topologically defined polymers. In this contribution, we report a one-step synthesis of 3-miktoarm star terpolymers of poly(ethylene glycol)-star-poly(ε-caprolactone)-star-poly(ε-caprolactone-co-tetrahydrofuran) (PEG-star-PCL-star-P(CL-co-THF)) via Janus polymerization using lutetium triflates (Lu(OTf)3) and methoxypoly(ethylene glycol) epoxy (mPEG-EO) as catalyst and macroinitiator, respectively. Self-assembly of PEG-star-PCL-star-P(CL-co-THF) into vesicles in aqueous solution depends on the ratio of hydrophilic and hydrophobic block of the terpolymers. Coassembly of the terpolymer with a PCL homopolymer (MW = 3000), on the other hand, increases shell thickness and vesicle diameter. Furthermore, nanorods and needle-shaped aggregates featuring high aspect ratios are obtained upon self-assembly at an interface. This unique behavior can be attributed to crystallization of the PCL segments. Based on the biocompatible and biodegradable nature of the constituting segments, the herein described 3-miktoarm star terpolymers might be promising materials for drug/gene delivery or as bionanoreactors, especially as wall thickness and stiffness of the structures observed can be tuned. With that control over (nano)local permeability might be feasible.

Fabrication of high-numerical-aperture phase zone plates with a single lithography exposure and no etching (2003)

We present a process for fabricating phase zone plates and other diffractive-optical elements that is capable of achieving high resolution, requires only a single lithography step, and no etching. For this process we use the negative resist hydrogen silsesquioxane (HSQ) (Dow Corning), which is sensitive to both electrons and x rays. HSQ’s extraordinarily high resolution (∼10 nm) and its SiO2-like properties make it an optimal choice for fabricating diffractive-optical elements that operate in the ultraviolet and deep ultraviolet. HSQ has an index of refraction very close to that of fused silica, and a negligible absorption down to 157 nm. As a result, if it is spun to the thickness corresponding to the desired phase step for the optic, patterning and development are the only required process steps. It is often desirable to place an absorbing layer on the areas surrounding the diffractive elements to prevent unwanted radiation from reaching the substrate when the optics are used for lithography and microscopy applications. We have developed a method that achieves this by means of a metal evaporation followed by a selectively controlled chemical etching (Fulton/Dolan process). We present e-beam and x-ray lithographic exposures in HSQ of phase zone plate arrays, and provide a full description of the selectively controlled chemical etching process as applied to the fabrication of diffractive optics. The focusing properties of the fabricated arrays are also presented.
ZnO nanowire-based light-emitting diodes with tunable emission from near-UV to blue (2013)

Nanowires (NWs)-based light emitting diodes (LEDs) have drawn large interest due to many advantages compared to thin film based devices. We have successfully prepared epitaxial n-ZnO(NW)/p-GaN heterojunctions using low temperature soft electrochemical techniques. The structures have been used in LED devices and exhibited highly interesting performances. Moreover, the bandgap of ZnO has been tuned by Cu or Cd doping at controlled atomic concentration. A result was the controlled shift of the LED emission in the visible spectral wavelength region. Using DFT computing calculations, we have also shown that the bandgap narrowing has two different origins for Zn<sub>1-x</sub>Cd<sub>x</sub>O (ZnO:Cd) and ZnO:Cu. In the first case, it is due to the crystal lattice expansion, whereas in the second case Cu-3d donor and Cu-3d combined to O-2p acceptor bands appear in the bandgap which broadnesses increase with the dopant concentration. This leads to the bandgap reduction.
