Conference Report/IEEE OnlineGreenComm 2016 (2017)

Presents information on the 2016 IEEE OnlineGreenComm conference. From November 14-17, 2016, the IEEE Communications Society (ComSoc) hosted the annual IEEE Online Conference on Green Communications (IEEE Online- GreenComm’16). This sixth IEEE OnlieGreenComm conference served as forum for presenting and discussing novel research and technological developments in the area of green communications, networking, and computing. By keeping the online concept of previous events, IEEE OnlineGreenComm'16 continued in spirit of "energy efficient discussion about energy-efficiency," through the conference virtual communication platform, which offers a unique and unsurpassed networking and interaction experience. With the international webcasting of the complete conference program, IEEE OnlineGreenComm’16 attendees from industry and academia participated in conference events from the comfort of their own work and/or home environments. This ecological conferencing approach of IEEE OnlineGreen- Comm'16 contributes to the reduction of greenhouse gas emissions and costs by eliminating the need for conference travel, while providing the participants with time-flexible access to live or recorded OnlineGreenComm'16 events. In this way, the conference format of IEEE OnlineGreenComm'16 offers to presenters a truly worldwide audience, with the ability to answer questions in real time through interaction with session chairs and with the aid of webcast managers.
Configurations of adsorbed hard spheres after diffusion in a gravitational field. (1992)

The deposition and adhesion of particles on a solid surface are governed by a great number of interplaying forces. In this paper we analyze, by means of computer simulations, the influence of (i) the short-range repulsive forces, modeled by hard sphere interactions, (ii) the gravitational forces, and (iii) the diffusion process of the particles in the fluid on the structure of the surface covered by the particles. In particular, the evolution of the limiting coverage, [symbol, see text] infinity (where [symbol, see text] is the reduced relative surface coverage), and the radial distribution, g(r), at the jamming limit, are determined as a function of the gravitational forces. These forces play an important role in many experiments performed on latex beads. Our results should stimulate new experiments in this field and, thus, be directly experimentally tested. It is shown, for example, that for polystyrene particles [symbol, see text] infinity is constant and equal to the random sequential adsorption jamming limit value for radii R not larger than 1 micron. It increases for 1 </= R </= 3 micron and tends, for higher R, to a plateau, whose value is approximately equal to 0.61. The tendency to a closer packing when R is large, and thus large gravitational forces, is confirmed by the shape of the radial distribution function. This phenomenon occurs not only for jammed surfaces but also for unsaturated surfaces.
SOME RECENT PROGRESS IN THE CONTROL OF WHEEL/RAIL NOISE (1980)

Wheel/rail noise is generally divided into three categories: squeal, impact, and roar. Of the three, roar is the one category for which effective, system compatible noise control techniques for rapid transit systems have not been demonstrated. This paper reports on an on-going study that is focused on roar noise control through improved wheel designs and wheel/rail smoothing techniques. It discusses analysis and field measurements and noise control treatments, including a resiliently treated wheel.
Destabilization of the 3<sub>10</sub>-Helix in Peptides Based on C<sup>α</sup>-Tetrasubstituted α-Amino Acids by Main-Chain to Side-Chain Hydrogen Bonds (1998)

The homooligopeptide series based on O,O-isopropylidene-α-hydroxymethylserine from dimer through pentamer has been synthesized to examine the conformational preferences of this new Cα-tetrasubstituted α-amino acid characterized by concomitant Ciα ↔ Ciα cyclization and presence of two ether oxygen atoms in the γ-positions of the six-membered ring 1,3-dioxane system. To this aim we have exploited X-ray diffraction in the crystal state and FTIR absorption and 1H NMR techniques in solution. The results obtained are compared with those of the homooligopeptides based on the related cyclohexane-containing Cα-tetrasubstituted residue. We conclude that in the former peptides a competition takes place between the classical intramolecular (peptide) CO···H−N (peptide) H-bonds, stabilizing the β-bend/310-helical structures, and the newly discovered (peptide) Ni+1−H···Oiγ (side-chain ether) intramolecular H-bonds. The extent of regular (incipient) 310-helix formation, where this latter type of H-bond is absent, tends to increase as peptide main-chain length increases. As a result of this intramolecular N−H···Oγ interaction, the critical main-chain length for 310-helix formation in the crystal state shifts from the shortest possible oligomer, the terminally protected trimer, in the cyclohexane series to the pentamer in the 1,3-dioxane series. Interestingly, a strict correlation has been found between the observed (peptide) Ni+1−H···Oiγ (side-chain ether) intramolecular H-bond and (i) the backbone ψ torsion angle of the i residue (extended), and (ii) the disposition of the α-amino substituent in the 1,3-dioxane ring of the i + 1 residue (axial).
In vivo formation of gene fusions encoding hybrid beta-galactosidase proteins in one step with a transposable Mu-lac transducing phage. (1984)

A Mu-lac bacteriophage transposon, MudII301 (Ap, lac), was constructed to form hybrid protein gene fusions. When it integrates into structural genes in the appropriate direction and reading phase, transcription and translation from outside gene controlling regions can proceed across 116 nucleotides from the right end of Mu into lacZ codons to form hybrid proteins that are enzymatically active for beta-galactosidase. Integration can be obtained either by infection to form lysogens or by transposition during growth of a lysogen. The size of the hybrid protein product either corresponds to or, in the cases of translation restart or protein degradation, is a minimal estimate of the distance of the Mu insertion from the translation initiation site of the gene. Hybrid proteins formed by insertions in randomly selected genes and in the araB and A genes were examined by polyacrylamide gel electrophoresis.
Treatment of Neuroleptic-Induced Akathisia With the 5-HT2A Antagonist Trazodone (2003)

Akathisia is a common and distressful extrapyramidal adverse side effect usually resulting from the use of antipsychotic medications. Early management of akathisia is important because it may be associated with poor treatment response and medication noncompliance. Unfortunately many patients fail to respond to standard management of akathisia. In addition to dopaminergic mechanisms, it has been hypothesized that serotonin may play a prominent role in the pathophysiology of akathisia. Trazodone is an antidepressant agent demonstrating prominent serotonergic antagonistic properties. This open-label pilot study investigates the efficacy of trazodone in the management of akathisia. Nine female patients with a score of at least "mild akathisia" on the Barnes Akathisia Scale, and receiving a stable dose of antipsychotic medication, were administered trazodone, titrated up to a dosage of 100 mg/day over a period of 5 days. The patients demonstrated marked improvement in symptoms of akathisia. In addition, some improvement was noted in symptomatology of anxiety, depression, and psychosis. These observations suggest the use of trazodone as a beneficial and relatively safe medication for the treatment of antipsychotic medication-induced akathisia. Further study in the context of a double-blind, placebo-controlled trial is mandated to substantiate these preliminary findings.
Biodegradation of the Polyketide Toxin Cercosporin (2002)

Cercosporin is a non-host-specific polyketide toxin produced by many species of plant pathogens belonging to the genus Cercospora. This red-pigmented, light-activated toxin is an important pathogenicity determinant for Cercospora species. In this study, we screened 244 bacterial isolates representing 12 different genera for the ability to degrade cercosporin. Cercosporin degradation was determined by screening for the presence of cleared zones surrounding colonies on cercosporin-containing culture medium and was confirmed by assaying the kinetics of degradation in liquid medium. Bacteria belonging to four different genera exhibited the cercosporin-degrading phenotype. The isolates with the greatest cercosporin-degrading activity belonged to Xanthomonas campestris pv. zinniae and X. campestris pv. pruni. Isolates of these pathovars removed over 90% of the cercosporin from culture medium within 48 h. Bacterial degradation of red cercosporin was accompanied by a shift in the color of the growth medium to brown and then green. The disappearance of cercosporin was accompanied by the appearance of a transient green product, designated xanosporic acid. Xanosporic acid and its more stable lactone derivative, xanosporolactone, are nontoxic to cercosporin-sensitive fungi and to plant tissue and are labile in the presence of light. Detailed spectroscopic analysis (to be reported in a separate publication) of xanosporolactone revealed that cercosporin loses one methoxyl group and gains one oxygen atom in the bacterial conversion. The resulting chromophore (4,9-dihydroxy-3-oxaperlylen-10H-10-one) has never been reported before but is biosynthetically plausible via oxygen insertion by a cytochrome P-450 enzyme.
MATERNAL SERUM ALPHA‐FETOPROTEIN AND PREVIOUS NEURAL TUBE DEFECTS (1976)

Summary A case‐control study involving 63 pregnancies showed that women who had previously had an infant with anencephaly or spina bifida did not have raised serum alpha‐fetoprotein (AFP) levels in subsequent unaffected pregnancies. The value of a serum AFP determination in such women is discussed. If the serum AFP level is normal and if ultrasonography excludes anencephaly the risk of spina bifida might be low enough (about 1 per cent) to make diagnostic amniocentesis difficult to justify. Conversely, a high serum AFP value in such women should not be acted on without confirmation of an abnormality by ultrasonography and, if that is negative, by diagnostic amniocentesis.

Oxidized Low-Density Lipoprotein Antigen Transport Induces Autoimmunity in the Renal Tubulointerstitium (2012)

These data demonstrate that the tubulointerstitial inflammatory infiltrate that accompanies chronic kidney disease reflects, at least in part, the development of autoimmunity to novel antigens generated during renal injury.
Dimerization and polymerization of butadiene with zero‐valent nickel and protonic acids (1973)

Abstract The behavior of hydridonickel coordination compounds as catalysts for the oligomerization and polymerization of butadiene in various solvents was studied. In the presence of alcohol bis(tricyclohexylphosphine)chlorohydridonickel ( 4 , X = Cl) (HNiCl[P(C 6 H 11 ) 3 ] 2 ) catalyzes the linear dimerization. With hydridotetrakis(phosphite)nickel(1+) ( 2 ) ([HNi{P(OR) 3 } 4 ] + ), which is prepared from tetrakis(phosphite)nickel ( 1 ) (Ni[P(OR) 3 ] 4 ) and trifluoroacetic acid, dimerization occurs in sec ‐alcohol but there is no reaction in tert ‐alcohol. The main product is 2‐methylenevinylcyclopentane ( 8 ). The other products are 4‐vinylcyclohexene ( 10 ), 1,5‐cyclooctadiene ( 5 ), 1,3,7‐octatriene ( 7 ) and 1,3,6‐octatriene ( 9 ). The hydridonickel coordination compound, prepared with inorganic acids, does not afford the dimers but the 1,4‐ trans polymer.

Location and Motion of Isotropic Paramagnetic Centres in Synthetic Monohydrocalcite (1994)

The isotropic CO - 2 and CO - 3 centres in CaCO 3 ·H 2 O were examined with electron spin resonance (ESR), electron-nuclear double resonance (ENDOR) and thermogravimetric analysis (TGA). From the absence of anisotropy and the small value of the 1 H ENDOR splitting ( ∼0.3 MHz), the effect of crushing and/or thermal annealing on the ESR and TGA spectra, it is concluded that both isotropic centres are located in the occluded water, surrounding the constituent crystallites of the spherulites. ESR line width and 13 C hyperfine coupling parameter measurements yield approximate values for the rotation activation energy (Δ E ( CO 3 - <Δ E ( CO 2 - ) with Δ E ∼ 0.2 eV) and for the vibrational frequency ( ∼2.10 12 Hz for CO 2 - ).
Novel Genes and Regulators That Influence Production of Cell Surface Exopolysaccharides in Sinorhizobium meliloti (2017)

<i>Sinorhizobium meliloti</i> is a soil-dwelling alphaproteobacterium that engages in a nitrogen-fixing root nodule symbiosis with leguminous plants. Cell surface polysaccharides are important both for adapting to stresses in the soil and for the development of an effective symbiotic interaction. Among the polysaccharides characterized to date, the acidic exopolysaccharides I (EPS-I; succinoglycan) and II (EPS-II; galactoglucan) are particularly important for protection from abiotic stresses, biofilm formation, root colonization, and infection of plant roots. Previous genetic screens discovered mutants with impaired EPS production, allowing the delineation of EPS biosynthetic pathways. Here we report on a genetic screen to isolate mutants with mucoid colonial morphologies that suggest EPS overproduction. Screening with Tn<i>5</i>-110, which allows the recovery of both null and upregulation mutants, yielded 47 mucoid mutants, most of which overproduce EPS-I; among the 30 unique genes and intergenic regions identified, 14 have not been associated with EPS production previously. We identified a new protein-coding gene, <i>emmD</i>, which may be involved in the regulation of EPS-I production as part of the EmmABC three-component regulatory circuit. We also identified a mutant defective in EPS-I production, motility, and symbiosis, where Tn<i>5</i>-110 was not responsible for the mutant phenotypes; these phenotypes result from a missense mutation in <i>rpoA</i> corresponding to the domain of the RNA polymerase alpha subunit known to interact with transcription regulators.<b>IMPORTANCE</b> The alphaproteobacterium <i>Sinorhizobium meliloti</i> converts dinitrogen to ammonium while inhabiting specialized plant organs termed root nodules. The transformation of <i>S. meliloti</i> from a free-living soil bacterium to a nitrogen-fixing plant symbiont is a complex developmental process requiring close interaction between the two partners. As the interface between the bacterium and its environment, the <i>S. meliloti</i> cell surface plays a critical role in adaptation to varied soil environments and in interaction with plant hosts. We isolated and characterized <i>S. meliloti</i> mutants with increased production of exopolysaccharides, key cell surface components. Our diverse set of mutants suggests roles for exopolysaccharide production in growth, metabolism, cell division, envelope homeostasis, biofilm formation, stress response, motility, and symbiosis.
Theoretical investigation of using a yellow (577nm) laser for diabetic retinopathy (2020)

We present a theoretical analysis of laser coagulation for diabetic retinopathy (DR) eye surgery procedures. Using a Monte-Carlo multi-layer (MCML) simulation and a finite element model of the human eye, we derive the optimal surgery conditions and address the long standing debate regarding the best laser wavelength to be used. The differences between yellow (577nm) and green (532nm) lasers, which are the commonly used wavelengths for this procedure, have been studied previously, mostly via empirical studies. Here, to the best of our knowledge, we introduce for the first time a quantitative theoretical analysis to determine the best laser wavelength. Using our analysis, we determine optimal laser operation conditions for treating DR with minimal damage to the surrounding tissue. We show that under these conditions, the yellow laser is significantly favorable.

Shelf and cycle life evaluation of silver--zinc cells. [Various separators] (1969)

Sterilized and control silver--zinc cells with various separator systems were given extended shelf and cycle life tests. Only cells with a separator system of methacrylic acid graft on cross-linked polyethylene were not sterilized. The data showed that the open-circuit voltage cannot be used to predict the capacity of a silver--zinc cell; but, if the open-circuit voltage of a cell drops below 1.58 V, the cell is shorted and cannot be rejuvenated.
Integration and application of vitrified collagen in multilayered microfluidic devices for corneal microtissue culture (2009)

This paper describes the fabrication and application of microfluidic devices containing collagen vitrigel (CV) used as both a functional and sacrificial cell growth substrate for the development of corneal microtissue patches. Within the device, vacuum fixation of the CV in a dehydrated state enables quick integration with standard multilayer soft lithographic techniques, while on-chip rehydration results in a gel-like collagen substrate for microfluidic cell culture. Fluidic connectivity to both the apical and basal side of the CV permits bilayered culture of epithelium and supporting stromal cell layers. In addition, microfluidic introduction of a collagenase etching media enables sacrificial degradation of the supporting CV membrane for development of barrier tissue constructs containing minimal synthetic substrate. The utility of this platform was evaluated by miniaturizing the standard transepithelial permeability (TEP) assay in order to measure the integrity of an array of corneal tissue micropatches.
Crystal structure and physical properties of a novel Kondo antiferromagnet: U<sub>3</sub>Ru<sub>4</sub>Al<sub>12</sub> (2009)

A novel ternary compound U(3)Ru(4)Al(12) has been identified in the U-Ru-Al ternary diagram. Single-crystal x-ray diffraction indicates a hexagonal Gd(3)Ru(4)Al(12)-type structure for this uranium-based intermetallic. While this structure type usually induces geometrically a spin-glass behaviour, an antiferromagnetic ordering is observed at T(N) = 8.4 K in the present case. The reduced effective magnetic moment of U atoms (μ(eff) = 2.6 µ(B)) can be explained by Kondo-like interactions and crystal field effects that have been identified by a logarithmic temperature dependence of the electrical resistivity, negative values of the magnetoresistivity and particular shape of the Seebeck coefficient.
Physiological and psychological effects of Hatha-Yoga exercise in healthy women. (1994)

Hatha-Yoga has become increasingly popular in western countries as a method for coping with stress. However, little is known about the physiological and psychological effects of yoga practice. We measured heart rate, blood pressure, the hormones cortisol, prolactin and growth hormone and certain psychological parameters in a yoga practicing group and a control group of young female volunteers reading in a comfortable position during the experimental period. There were no substantial differences between the groups concerning endocrine parameters and blood pressure. The course of heart rate was significantly different, the yoga group had a decrease during the yoga practice. Significant differences between both groups were found in psychological parameters. In the personality inventory the yoga group showed markedly higher scores in life satisfaction and lower scores in excitability, aggressiveness, openness, emotionality and somatic complaints. Significant differences could also be observed concerning coping with stress and the mood at the end of the experiment. The yoga group had significant higher scores in high spirits and extravertedness.

Structural behaviour of distressed and strengthened post-tensioned box beams (2009)

This study focuses on the behaviour of post-tensioned box beams with snapped prestress cables. It also includes an investigation into the effectiveness of using select strengthening methods on distressed box beams. All beams were subjected to flexural-shear-torsional loads. The results show that snapping 15% of the prestressing cable area resulted in a 74% increase in deformation at service load and a 22% decrease in ultimate load. The snapping of prestress wires also increased the stresses in the snapped cables by 70%. All the strengthening techniques used effectively restored the beam performance at service and overcame the effect of cable snapping.
Manufacturing Complex Silica Aerogel Target Components (2009)

Aerogel is a material used in numerous components for inertial confinement fusion and high-energy density physics targets. In the past, these components were molded into the proper shapes. Artifacts left in the parts from the molding process, contour irregularities from shrinkage, and density gradients caused by the skin have caused Los Alamos National Laboratory to pursue machining as a way to make the components. The machining of aerogel is an involved process, and many manufacturing aspects need to be considered including holding the material for machining, achieving the desired surface roughness and the desired dimensional accuracy, conceivably producing a part with enhanced dimensional tolerance and minimal density variations. Therefore, an effort has been established to develop a method to more accurately determine density errors, perform machining experiments, acquire physical property data, and model the machining process.
A 1,4-β-glucan glucanohydrolase from the cellulolytic fungus <i>Trichoderma viride</i> QM 9414. Purification, characterization and preparation of an immunoadsorbent for the enzyme (1979)

A 1,4-beta-glucan glucanohydrolase (EC 3.2.1.4) was isolated from culture filtrates of the fungus Trichoderma viride QM 9414 by molecular-sieve chromatography on Bio-Gel P-30, ion-exchange chromatography on DEAE-Sephadex A-50 and isoelectric focusing in a density gradient. Polyacrylamide-gel electrophoresis at two different pH values, analytical isoelectric focusing in a polyacrylamide-gel slab and molecular-sieve chromatography of the reduced and alkylated enzyme in a denaturing medium indicated a homogeneous protein. The enzyme has a mol.wt. of 51,000 and is not a glycoprotein. The pI was found to be 4.66 at 23 degrees C. Antiserum against the purified enzyme was prepared and the amount of enzyme in the original filtrate was determined by rocket immunoelectrophoresis to be about 50mg/liter. An immunoadsorbent made from CNBr-activated sepharose 4B and antiserum affords a rapid and highly specific purification of the enzyme.
