Global effects of the DEAD‐box RNA helicase DeaD (CsdA) on gene expression over a broad range of temperatures (2014)

In Escherichia coli, activity of the global regulatory RNA binding protein CsrA is antagonized by two non-coding sRNAs, CsrB and CsrC, which sequester it away from its lower affinity mRNA targets. Transcription of csrB/C requires the BarA-UvrY two component signal transduction system, which responds to short chain carboxylates. We show that two DEAD-box RNA helicases, DeaD and SrmB, activate csrB/C expression by different pathways. DeaD facilitates uvrY translation by counteracting the inhibitory effect of long distance base-pairing between the uvrY mRNA leader and coding region, while SrmB does not affect UvrY or UvrY-phosphate levels. Contrary to the prevailing notion that these helicases act primarily at low temperatures, DeaD and SrmB activated csrB expression over a wide temperature range. High-throughput sequencing of RNA isolated by cross-linking immunoprecipitation (HITS-CLIP) revealed in vivo interactions of DeaD with 39 mRNAs, including those of uvrY and 9 other regulatory genes. Studies on the expression of several of the identified genes revealed regulatory effects of DeaD in all cases and diverse temperature response patterns. Our findings uncover an expanded regulatory role for DeaD, which is mediated through novel mRNA targets, important global regulators and under physiological conditions that were considered to be incompatible with its function.
Enhancing the optoelectronic properties of amorphous zinc tin oxide by subgap defect passivation: A theoretical and experimental demonstration (2017)

The link between sub-bandgap states and optoelectronic properties is investigated for amorphous zinc tin oxide (a-ZTO) thin films deposited by RF sputtering. a-ZTO samples were annealed up to 500 \ifmmode^\circ\else\textdegree\fi{}C in oxidizing, neutral, and reducing atmospheres before characterizing their structural and optoelectronic properties by photothermal deflection spectroscopy, near-infrared-visible UV spectrophotometry, Hall effect, Rutherford backscattering, hydrogen forward scattering and transmission electron microscopy. By combining the experimental results with density functional theory calculations, oxygen deficiencies and resulting metal atoms clusters are identified as the source of subgap states, some of which act as electron donors but also as free electron scattering centers. The role of hydrogen on the optoelectronic properties is also discussed. Based on this detailed understanding of the different point defects present in a-ZTO, their impact on optoelectronic properties, and how they can be suppressed by postdeposition annealing treatments, an amorphous indium-free transparent conductive oxide, with a high thermal stability and an electron mobility up to $35\phantom{\rule{0.28em}{0ex}}\mathrm{c}{\mathrm{m}}^{2}\phantom{\rule{0.16em}{0ex}}{\mathrm{V}}^{\ensuremath{-}1}\phantom{\rule{0.16em}{0ex}}{\mathrm{s}}^{\ensuremath{-}1}$, is demonstrated by defect passivation.
El Señor de Malta. Partida y regreso de un crucificado dramático pintado por el demonio. (2019)

espanolA finales del siglo XVIII un expresionista y sangriento crucificado bajo la advocacion de Cristo de Malta, fue objeto de multiples copias anonimas en pintura y escultura. Las dispares leyendas en torno a su origen y su difusion mas alla de la cordillera andina han dificultado sucesivamente su investigacion. El presente estudio pretende desvelar los origenes italianos y centroeuropeos de este Crucificado doloroso, formando parte de una dilatada historia con raices en el Medievo. Paralelamente se analizan las circunstancias en las que aparecio esta iconografia cristifera vinculada a las epidemias o la evangelizacion y cuestionada o divulgada por la propia Contrarreforma. EnglishAt the end of the 18th century, an expressionist and bloody crucifixion scene dedicated to the Christ of Malta was the subject of multiple anonymous copies in painting and sculpture. The dissimilar legends surrounding its origin and its diffusion beyond the Andes mountain range have hindered its research. The present study attempts to reveal the Italian and Central European origins of this agonizing crucifixion, part of a long history with roots in the Middle Ages. Concurrently, it analyzes the circumstances in which this Christian iconography appeared linked to epidemics or evangelization, and was questioned or divulged by the Counter-Reformation itself.
Properties of oriented film tapes prepared via solid-state processing of a nascent ultrahigh-molecular-weight polyethylene reactor powder synthesized with a postmetallocene catalyst (2012)

The correlation between the molecular mass of a nascent ultrahigh-molecular-weight polyethylene reactor powder synthesized with a postmetallocene catalyst and the specific features of plastic deformation during the orientational drawing of the material compacted and consolidated under laboratory conditions is studied. In the range 5 × 106−7 × 106, molecular mass is controlled via a change in the polymerization conditions. Under comparable conditions of orientational drawing, the highest values of strength (2.65 GPa) and the elastic modulus (100 GPa) are found for samples with M = 6.3 × 106.

LABORATORY COMPARISON OF AEDES AEGYPTI ATTRACTION TO HUMAN ODORS AND TO SYNTHETIC HUMAN ODOR COMPOUNDS AND BLENDS1 (2007)

Chemical lures can enhance the ability of traps to collect mosquitoes, selectively target species for capture, and provide a realistic assessment of the species and host-equivalent numbers of mosquitoes present in the local area. One approach to the development of chemical lures is to manufacture blends that comprise odors released in human emanations. These blends need to be safe for use in the environment, desirable from an economic standpoint, and transportable to the field for use in traps. In this report, we compared the attraction of mosquitoes to various chemicals, blends, and odors from humans. Noncompetitive (single-treatment) bioassays established that some blends are equivalent or more attractive to Aedes aegypti than human odors. Competitive bioassays were conducted; these involved simultaneous comparison of 2 treatments: single compounds to binary blends; binary blends to a trinary blend of L-lactic acid, acetone, and dimethyl disulfide; and the trinary blend to human odors from 3 volunteers. The overall trend was that the trinary blend was more attractive than binary blends, and binary blends were more attractive than single compounds. However, human odors were still significantly more attractive than the trinary blend. Therefore, further modifications and refinements to blends will be needed to better compete against human odors.

Point-based probabilistic surfaces to show surface uncertainty (2004)

Efficient and informative visualization of surfaces with uncertainties is an important topic with many applications in science and engineering. In these applications, the correct course of action may depend not only on the location of a boundary, but on the precision with which that location is known. Examples include environmental pollution borderline detection, oil basin edge characterization, or discrimination between cancerous and healthy tissue in medicine. This paper presents a method for producing visualizations of surfaces with uncertainties using points as display primitives. Our approach is to render the surface as a collection of points and to displace each point from its original location along the surface normal by an amount proportional to the uncertainty at that point. This approaoh can be used in combination with other techniques such as pseudocoloring to produce efficient and revealing visualizations. The basic approach is sufficiently flexible to allow natural extensions; we show incorporation of expressive modulation of opacity, change of the stroke primitive, and addition of an underlying polygonal model. The method is used to visualize real and simulated tumor formations with uncertainty of tumor boundaries. The point-based technique is compared to pseudocoloring for a position estimation task in a preliminary user study.
Abstract SY08-02: Markers of caspase activation in cells and serum (2011)

Abstract The final and hoped for outcome for treatment with cancer drugs is selective apoptosis of cancer cells. However, despite the low response rates to cancer drugs patients do not discover this until months after treatment has begun. Apoptosis is rapid process which is often induced within 24 hours of drug treatment. The hallmark of apoptosis is the activation of caspases, cysteine proteases that are specific for cleaving target proteins after aspartic acid. We have developed a novel proteomics technology that allows us to tag and enrich for caspase-cleaved proteins during apoptosis (Mahrus et al (2008) Cell, 134, 866-876. “Global Sequencing of Proteolytic Cleavage Sites in Apoptosis by Specific Labeling of Protein N Termini”). We have been characterizing the apoptotic products of caspase cleavage in a variety of cell lines and in human serum with the view that this information can be used to monitor apoptosis during cancer drug treatment. These and other studies in a variety of cancer cell lines showed that upwards of 1000 proteins are cleaved by caspases during apoptosis. However, in any given cell line we find there are fewer than 500 targets because of differences in expression patterns between cell types. Thus, while many targets are in common from one cell line to another, many are unique. We have developed single-reaction monitoring (SRM) methods to identify these products in serum. We are beginning to identify specific apoptotic products in leukemia patients treated with various cancer drugs. These studies and the prospects for using these as apoptotic markers to assist in cancer drug treatment will be discussed. Citation Format: {Authors}. {Abstract title} [abstract].

Nitride-Based High-Power Flip-Chip LED With Double-Side Patterned Sapphire Substrate (2007)

A nitride-based high-power flip-chip (FC) light-emitting diode (LED) with a double-side patterned sapphire substrate (PSS) was proposed and realized. Under 350-mA current injection, it was found that forward voltages were 3.24, 3.26, and 3.25 V for the conventional FC LED, FC LED prepared on PSS, and FC LED with double-side PSS, respectively. It was found that the 350-mA LED output powers were 79.3, 98.1, and 121.5 mW for the conventional FC LED, FC LED prepared on PSS, and FC LED with double-side PSS, respectively. In other words, we can enhance the electroluminescence intensity by 53% without increasing operation voltage of the fabricated LED

Stereochemical Interactions in Ammonium Dications, Hypervalent Diammonium Cation-Radicals and Ammonium Radicals. A B3-MP2 Computational Study (2003)

Hypervalent ammonium radicals and cation-radicals derived from cis and trans-cyclopentane-1,2-diamine have been studied computationally with the goal of elucidating intramolecular interactions between the ammonium and amine functional groups in a conformationally rigid model system. Hypervalent cis and trans-cyclopentane-1-ammonium-2-amine radicals are only marginally stable against dissociation by loss of an ammonium hydrogen atom and ammonia. The radicals are predicted to exhibit very similar dissociations originating from the ground and excited electronic states. The dissociation and transition state energies in bifunctional hypervalent ammonium radicals are analogous to those reported previously for monofunctional ammonium radicals. Stereochemical effects are predicted to occur in the formation and dissociations of hypervalent cis and trans-cyclopentane-1,2-diammonium cation-radicals. The cis-isomer is calculated to undergo very facile elimination of dihydrogen resulting from a dipolar H(+)....H(-) interaction between the ammonium groups. The trans-isomer is predicted to spontaneously dissociate to a complex of cyclopentene cation-radical and two ammonia molecules.
Approximation Algorithms for Grooming in Optical Network Design (2009)

We study traffic grooming in optical network design. The goal is to aggregate low-bandwidth traffic streams to efficiently utilize high-bandwidth media such as wavelength channels. More precisely, given traffic demands to be routed in a network, the design problem is to define a collection of light paths such that each demand can follow a sequence of consecutive light paths. Each light path has unit-wavelength bandwidth, and multiple sub-wavelength demands may share a common light path. Traffic must enter and depart from a light path at its two endpoints only. Most previous work on grooming focused on the ring topology and typically dealt only with uniform bandwidth demands, whereas we consider more general settings. We study two objectives. One is to minimize total equipment cost necessary to support the light paths; the other is simply to minimize the number of light paths. Even for the extremely restricted special case of a line topology and traffic demands that request half-wavelength bandwidth, we show that both objectives are APX-hard to optimize, which means we cannot approximate the optimum arbitrarily closely. On the other extreme of generality, for arbitrary network topologies and traffic demands that request arbitrary amounts of bandwidth, we show a logarithmic approximation for cost minimization and a 2-approximation for minimizing light path counts. Furthermore, we discover that the special case of half-wavelength demands has rich combinatorial properties, closely related to graph problems such as cycle packing and pattern matching problems such as interchange distance in strings. We show how to approximate both objectives up to small constant factors in this case, while similarly improving the approximation and hardness of the interchange distance problem as well.
An Ultraviolet Spectrophotometer for Satellite Astronomy (1964)

An astronomical Spectrophotometer is described which was designed for use on OSOB, the second U.S. Orbiting Solar Observatory. The Spectrophotometer is intended to analyze the ultraviolet emission from stars and nebulae. The entrance slit of the Spectrophotometer defines the field at the primary focus of a 6-inch modified Gregorian reflecting telescope. The secondary serves as the collimator for a rotating 1200 lines/mm plane reflection grating. Diffracted light from the grating is collected by an off-axis paraboloid and focused through the exit slit to the photomultiplier. The signal from the photomultiplier is pulse-counted and fed into the magnetic tape storage of the space-craft. The instrument utilizes the spin of the gyroscopically-stabilized satellite to sweep the 1°×0.4° over the celestial sphere. Slow precession of the spin axis allows eventual coverage of the whole sky. Ten adjacent wavelength bands of 180Å width between 1500Å and 3300Å are defined by succesive steps of the grating.
Photoinduced Birefringence and Surface Relief Gratings in Polyurethane Elastomers with Azobenzene Chromophore in the Hard Segment (2004)

A series of polyurethane elastomers containing aromatic azobenzene chromophore in the hard segment was synthesized by a one-step method. AFM surface study showed that particles on the order of 100 nm to several micrometers appeared after annealing the polymer films. Birefringence was induced in these polymer elastomers. The stability of the photoinduced birefringence could be improved significantly by annealing the polymer films. This also induced microphase separation. The effects of azo contents and molecular weight of soft segments were investigated. Dynamic study shows that photoinducing rate decreased while relaxation rate increased after annealing. Surface relief gratings could be induced only on the pure polyurethane and the elastomer containing 75% bis(azo)−diol. Only a reversible volume hologram was observed for the other elastomers.
Chemical Waves in the Iodide-Nitric Acid System (1994)

Chemical waves can be observed during the oxidation of iodide by 3-4.5 M nitric acid. The rate of the wave propagation and the wave shape under convection-free and convective conditions were studied using tub with differentdiametersand atvaryingorientations to thegravitationalvector. Theactivationenergyofthereactiondiffusion front wasdetermined. For the homogeneous reaction, the isothermal density change (ApJ wasmeasured and found to be negative. Because the reaction is exothermic, the Pojman and Epstein analysis of convective stability predicted only simple convection could occur. However, double-diffusive convection and fingering wereobserved. With special convection cells fed through permeable membranes we proved that double-diffusive convection could occur by having two solutal species (iodide and triiodide-starch complex) with significantly different diffusion coefficients and not only from competing thermal and solutal density changes. A mechanism for the angular dependence of the gravitational anisotropy in front velocities is proposed in terms of the Boycott effect.
Hypoxia Stimulates Urokinase Receptor Expression Through a Heme Protein-Dependent Pathway (1998)

Hypoxia underlies a number of biologic processes in which cellular migration and invasion occur. Because earlier studies have shown that the receptor for urokinase-type plasminogen activator (uPAR) may facilitate such events, we studied the effect of hypoxia on the expression of uPAR by first trimester human trophoblasts (HTR-8/SVneo) and human umbilical vein endothelial cells (HUVEC). Compared with control cells cultured under standard conditions (20% O2), HTR-8/SVneo cells and HUVEC cultured in 1% O2 expressed more uPAR, as determined by flow cytometric and [125I]-prourokinase ligand binding analyses. Increased uPAR expression paralleled increases in uPAR mRNA. The involvement of a heme protein in the hypoxia-induced expression of uPAR was suggested by the observations that culture of cells with cobalt chloride, or sodium 4, 5-dihydroxybenzene-1,3-disulfonate (Tiron), an iron-chelating agent, also stimulated uPAR expression, and that the hypoxia-induced uPAR expression was inhibited by adding carbon monoxide to the hypoxic atmosphere. Culture of HTR-8/SVneo cells with vascular endothelial growth factor (VEGF) did not increase uPAR mRNA levels, suggesting that the hypoxia-mediated effect on uPAR expression by these cells did not occur through a VEGF-dependent mechanism. The functional importance of these findings is suggested by the fact that HTR-8/SVneo cells cultured under hypoxia displayed higher levels of cell surface plasminogen activator activity and greater invasion through a reconstituted basement membrane. These results suggest that hypoxia may promote cellular invasion by stimulating the expression of uPAR through a heme protein-dependent pathway.

Clinical delivery system for intraperitoneal hyperthermic chemotherapy. (1980)

A 35-year-old man was treated for pseudomyxoma peritonei by surgery and by thermal infusion and chemotherapy with a machine designed specifically for the treatment of cancers of serosal surfaces. After extensive abdominal resection and closure, the patient's peritoneal cavity was instilled with 2.5 liters of 5% lactated Ringer's solution. He was then attached to hyperthermic perfusion system which elevated the i.p. temperature by warming (to 42 degrees) and recirculating the effusion solution. When the 42 degrees i.p. temperature was attained (after 1.5 hr), chemotherapy was added to the recirculating effusion. A second procedure followed 8 days later. The patient's postoperative course was uneventful except for minor pulmonary atelectasis with bacteremia. Hyperthermic perfusion was tolerated well and was evaluated as safe for intracavitary cancer treatment.
