Diversity analysis of pseudomonads in rice rhizosphere for multifaceted plant growth promotion (2011)

This investigation was carried out based on the hypothesis that there may be some pseudomonad strains, which could exist in rhizosphere of plant species contributing multifaceted beneficial activities. For this purpose, 21 pseudomonad isolates from the rhizosphere of rice, cultivated in western parts of Tamil Nadu were screened. All the 21 isolates were authenticated as pseudomonads by a genus-specific PCR screening. The molecular diversity of these isolates was investigated by Amplified Ribosomal DNA Restriction Analysis (ARDRA) and the dendrogram obtained from the analysis revealed that all the 21 isolates clustered into seven groups. Further, these isolates were screened for plant growth promoting activities such as diazotrophy (PCR amplification of nifH gene and acetylene reduction assay), Indole acetic acid (IAA) and siderophore production (spectrometrically), 1-Aminocyclopropane-1-carboxylic acid (ACC) deaminase for ethylene regulation (PCR screening), mineral solubilization (biochemically) and antagonistic potential against soil pathogenic fungi (dual culture assay). Based on the results, two elite Pseudomonas isolates (S9 and O3) were chosen as multi-functional plant growth-promoting rhizobacteria, paving way for potential use as bioinoculants in rice.
An output clamped series thyristor inverter (1979)

This paper describes an output clamped series thyristor inverter which operates independent of load at a high output frequency (over 20 kiloHertz). The basic operation of the new inverter is compared with the conventional series inverter. The paper also shows that, in the output clamped inverter, the load variation has a negligible effect on the ringing period. Finally, the logic requirements and implementation of an output clamped series inverter system for a portable line operated power supply are discussed.
Scanning geometry for broadly tunable single-mode pulsed dye lasers (1992)

We describe a scanning geometry for broadly tunable single-mode lasers that use a grazing-incidence grating as the dispersive element. This geometry is a generalized version of the Liu and Littman cavity [Opt. Lett. 6, 117 (1981)] but has much more flexibility in the configuration compared with theirs. Based on the present geometry, we have obtained a broad single-mode tuning range of 190 cm−1 for a pulsed dye laser.
Effect of Temperature on In Vivo Protein Synthetic Capacity in <i>Escherichia coli</i> (1998)

In this report, we examine the effect of temperature on protein synthesis. The rate of protein accumulation is determined by three factors: the number of working ribosomes, the rate at which ribosomes are working, and the rate of protein degradation. Measurements of RNA/protein ratios and the levels of individual ribosomal proteins and rRNA show that the cellular amount of ribosomal machinery in Escherichia coli is constant between 25 and 37 degreesC. Within this range, in a given medium, temperature affects ribosomal function the same as it affects overall growth. Two independent methodologies show that the peptide chain elongation rate increases as a function of temperature identically to growth rate up to 37 degreesC. Unlike the growth rate, however, the elongation rate continues to increase up to 44 degreesC at the same rate as between 25 and 37 degreesC. Our results show that the peptide elongation rate is not rate limiting for growth at high temperature. Taking into consideration the number of ribosomes per unit of cell mass, there is an apparent excess of protein synthetic capacity in these cells, indicating a dramatic increase in protein degradation at high temperature. Temperature shift experiments show that peptide chain elongation rate increases immediately, which supports a mechanism of heat shock response induction in which an increase in unfolded, newly translated protein induces this response. In addition, we find that at low temperature (15 degreesC), cells contain a pool of nontranslating ribosomes which do not contribute to cell growth, supporting the idea that there is a defect in initiation at low temperature.

Systemic PD149163, a neurotensin receptor 1 agonist, decreases methamphetamine self-administration in DBA/2J mice without causing excessive sedation (2017)

Methamphetamine (METH) is a psychostimulant that exhibits significant abuse potential. Although METH addiction is a major health and societal concern, no drug is currently approved for its therapeutic management. METH activates the central dopaminergic "reward" circuitry, and with repeated use increases levels of the neuromodulatory peptide neurotensin in the nucleus accumbens and ventral tegmental area. Previous studies in rats suggest that neurotensin agonism decreases METH self-administration, but these studies did not examine the effect of neurotensin agonism on the pattern of self-administration or open field locomotion. In our studies, we established intravenous METH self-administration in male, DBA/2J mice (fixed ratio 3, 2 hr sessions) and examined the effect of pretreatment with the NTS1 receptor agonist PD149163 on METH self-administration behavior. Locomotion following PD149163 was also measured up to 2 hours after injection on a rotarod and in an open field. Pretreatment with PD149163 (0.05 and 0.10 mg/kg, s.c.) significantly decreased METH self-administration. The pattern of responding suggested that PD149163 decreased motivation to self-administer METH initially in the session with more normal intake in the second hour of access. Voluntary movement in the open-field was significantly decreased by both 0.05 and 0.10 mg/kg (s.c.) PD149163 from 10-120 minutes after injection, but rotarod performance suggested that PD149163 did not cause frank sedation. These results suggest that a systemically delivered NTS1 receptor agonist decreases METH self-administration in mice. The pattern of self-administration suggests that PD149163 may acutely decrease motivation to self-administer METH before the drug is experienced, but cannot rule out that depression of voluntary movement plays a role in the decreased self-administration.
Joint rock physics inversion of elastic and electric attributes for rock and fluid properties – A real data example (2014)

Summary Estimation of reservoir properties and monitoring of fluid flow is an important modeling component in hydrocarbon exploration and production. Geophysical data (elastic and electrical) and reservoir rock properties can be linked via rock physics models. In this application, we develop a joint inversion approach of P-wave velocity and resistivity well logs for total porosity and total volume of fluid. We applied our inversion workflow to wireline data measured at the well location of the Rock Springs Uplift, Wyoming, USA, a potential CO2 storage reservoir. The inversion scheme is applied to the actual well dataset and to the same set of well logs filtered at lower resolutions. Results show that the rock and fluid volumes, or at least their trends in the case of filtered data, were predicted by the inversion scheme. Although the method was applied only at the well location, the inversion workflow can be extended to the entire reservoir model to predict the rock and fluid properties of the reservoir away from the well location.
Strong spatial dispersion in wire media in the very large wavelength limit (2003)

It is found that there exist composite media that exhibit strong spatial dispersion even in the very large wavelength limit. This follows from the study of lattices of ideally conducting parallel thin wires (wire media). In fact, our analysis reveals that the description of this medium by means of a local dispersive uniaxial dielectric tensor is not complete, leading to unphysical results for the propagation of electromagnetic waves at any frequencies. Since nonlocal constitutive relations have been usually considered in the past as a second-order approximation, meaningful in the short-wavelength limit, the aforementioned result presents a relevant theoretical interest. In addition, since such wire media have been recently used as a constituent of some discrete artificial media (or metamaterials), the reported results open the question of the relevance of the spatial dispersion in the characterization of these artificial media.
Titanium Containing γ‐MnO<sub>2</sub> (TM) Hollow Spheres: One‐Step Synthesis and Catalytic Activities in Li/Air Batteries and Oxidative Chemical Reactions (2010)

Abstract Titanium containing γ‐MnO 2 octahedral molecular sieves having hollow sphere structures are successfully prepared for the first time using a one‐step synthesis method. Titanium cations are used as structure‐directing agents in the synthesis process. The assembly of the hollow spheres is carried out at the beginning of the process. Various techniques including XRD, N 2 adsorption, SEM, EDX, RAMAN, TEM, XPS, and TGA are employed for the materials characterization. Ti is incorporated into the MnO 2 framework in isolated sites, and TiO 2 phases (anatase and rutile) are not observed. When introduced in medium‐sized lithium‐air batteries, the materials give very high specific capacity (up to 2.3 A h g −1 ). These materials are also catalytically tested in the oxidation of toluene with molecular oxygen at atmospheric pressure, showing significant oxidative catalytic activities in this difficult chemical reaction.
Split and merge data association filter for dense multi-target tracking (2004)

Bayesian target tracking methods consist in filtering successive measurements coming from a detector. In the presence of clutter or multiple targets, the filter must be coupled with an association procedure. The classical Bayesian multitarget tracking methods rely on the hypothesis that a target can generate at most one measurement per scan and that a measurement originates from at most one target. When tracking a high number of deformable sources, the previous assumptions are often not met that leads to the failure of the existing methods. Here, we propose an algorithm which allows to perform the tracking in the cases when a single target generates several measurements or several targets generate a single measurement. The novel idea presented in this paper is the introduction of a set that we call virtual measurement set which supersedes and extends the set of measurements. This set is chosen to optimally fit the set of the predicted measurements at each time step. This is done in two stages: i) a set of feasible joint association events is built from virtual measurements that are created by successively splitting and merging the real measurements; ii) the joint probability is maximized over all feasible joint association events. The method has been tested on microscopy image sequences which typically contains densely moving objects and gives satisfactory preliminary results.
The kinetics of ozone decomposition in water, the influence of pH and temperature (2009)

The influence of pH on the kinetics of ozone decomposition in water was studied. Over the pH range 1–8, the kinetics was well described by a second-order reaction equation. Starting with approximately pH 3, the pH dependence of the logarithm of the constant at 19°C corresponded to the equation logk= −2.66 + (0.49 ± 0.03)pH. The activation energy of ozone decomposition was found to be 76.0 ± 8.3 kJ/mol.
Initial genome scan of the NIMH genetics initiative bipolar pedigrees: Chromosomes 1, 6, 8, 10, and 12 (1997)

A report on an initial genome screen on 540 individuals in 97 families was collected as part of the NIMH Genetics Initiative on Bipolar Disorder. Families were ascertained to be informative for genetic linkage and underwent a common ascertainment and assessment protocol at four clinical sites. The sample was genotyped for 65 highly polymorphic markers from chromosomes 1, 6, 8, 10, and 12. The average intermarker interval was 16 cM. Genotypic data was analyzed using affected sib pair, multipoint affected sib pair, and pedigree analysis methods. Multipoint methods gave lod scores of approximately two on chromosomes 1, 6, and 10. The peak lod score on chromosome 6 occurred at the end of the q-arm, at some distance from the 6p24-22 area previously implicated for schizophrenia. We are currently genotyping additional markers to reduce the intermarker interval around the signals. The interpretation of results from a genome screen of a complex disorder and the problem of achieving a balance between detecting false positive results and the ability to detect genes of modest effect are discussed.
Oxygen accelerates the accumulation of mutations during the senescence and immortalization of murine cells in culture (2003)

Oxidative damage is a causal factor in aging and cancer, but it is still not clear how DNA damage, the cellular responses to such damage and its conversion to mutations by misrepair or misreplication contribute to these processes. Using transgenic mice carrying a lacZ mutation reporter, we have previously shown that mutations increase with age in most organs and tissues in vivo. It has also been previously shown that mouse cells respond to oxidative stress, typical of standard culture conditions, by undergoing cellular senescence. To understand better the consequences of oxidative stress, we cultured mouse embryo fibroblasts (MEFs) from lacZ mice under physiological oxygen tension (3%) or the high oxygen tension (20%) associated with standard culture, and determined the frequency and spectrum of mutations. Upon primary culture, the mutation frequency was found to increase approximately three-fold relative to the embryo. The majority of mutations were genome rearrangements. Subsequent culture in 20% oxygen resulted in senescence, followed by spontaneous immortalization. Immortalization was accompanied by an additional three-fold increase in mutations, most of which were G:C to T:A transversions, a signature mutation of oxidative DNA damage. In 3% oxygen, by contrast, MEFs did not senesce and the mutation frequency and spectrum remained similar to primary cultures. These findings demonstrate for the first time the impact of oxidative stress on the genomic integrity of murine cells during senescence and immortalization.
SSB‐Assisted Duplex Invasion of Preorganized PNA into Double‐Stranded DNA (2009)

Invasion of the DNA snatchers: We show that one strand of decamer DKα-PNA efficiently invades into double-stranded DNA (dsDNA) by utilizing the SSB-assisted duplex invasion. An extensive analysis of DKα-PNA–DNA duplex formation performed by calculation of the thermodynamic parameters and circular dichroism experiments ascertained that a right-handed helical preorganization is a very important contribution when one PNA strand invades into dsDNA.

Preliminary Study Of Triple Photon Coincidence Imaging Technique (1988)

Preliminary study of triple photon coincidence imaging technique (TPCIT) is presented for two imaging modes of angular unconstrained and constrained coincidence triple photons. The angular unconstrained triple photon coincidence mode reconstructs source distribution by small source volume fields (z 1.0 x 1.0 x 1.0 cm 3), each of which is specified by the intersection of three hollow cones generated from a triple photon coincidene event. Each hollow cone represents a source probability field of a photon undergoing an electronic collimation of scattering-absorption process. The angular constrained triple photon coincidence mode determines two small source volume fields from each triple photon coincidence event. The two volume fields are specified by the intersections of a hollow cone generated by a photon and a solid cylinder generated by another two photons from a positron annihilation with 180 degrees constaint. A truncated spherical detector system for brain imaging studies is proposed for quantitative analysis on resolution, sensitivity, and signal to noise ratio. The nuclear isoto,Re of Hf ;12 for the angular unconstrained TPCIT and Cs lgi for the angular constrained TPCIT are among many other isotopes, used for quantitative calculation. A comparison of the proposed imaging system with customary SPECT and PET is reported.
Acanthamoeba Keratitis: The Role of Domestic Tap Water Contamination in the United Kingdom (2003)

Water storage tanks promote colonization of domestic water with FLA, including Acanthamoeba, and hence increase the risk of AK. This accounts for the significantly greater incidence of AK in the UK and supports advice to avoid using tap water in contact lens care routines.
Measurement theory with applications to decisionmaking, utility, and the social sciences (1979)

This book provides an introduction to measurement theory for non-specialists and puts measurement in the social and behavioural sciences on a firm mathematical foundation. Results are applied to such topics as measurement of utility, psychophysical scaling and decision-making about pollution, energy, transportation and health. The results and questions presented should be of interest to both students and practising mathematicians since the author sets forth an area of mathematics unfamiliar to most mathematicians, but which has many potentially significant applications
Topography measurement of freeform specular surfaces using experimental ray tracing and radial basis functions (2016)

Optical deflectometric methods with their inherent potential of high channel capacity with regard to information theory has been of great interest for specular surface topography measurement, where the limited dynamic range needs to be considered in the detection plane. Achieving a final smooth reconstructed surface is the next challenge, because the 2Dintegration methods for the interpolation of the derived data from such sensors are prone to various sources of error such as path dependency, large data sets and secondary reflections. On the other hand, Radial Basis Functions have been studied in this respect for the last years and their characteristics have been widely discussed. In this paper, we introduce our approach for the 3D measurement of specular surfaces by means of Experimental Ray Tracing and Radial Basis Functions integration. We present simulations and discuss the reconstructed surface and the resulting reconstruction error results.
Sol−Gel Prepared Pt-Modified Oxide Layers:  Synthesis, Characterization, and Electrocatalytic Activity (2006)

Thin films of pure RuO2 and IrO2 and mixed Ru0.5Ir0.5O2 oxide modified with Pt particles were prepared by a sol-gel method in the form of thin films of similar to 2 mu m thickness on Ti substrates. Surface morphology of these Pt- modified oxides was examined by scanning electron microscopy and was found to exhibit a significant influence of the chemical composition of the oxide matrix. Element mapping showed homogeneous distribution of the metals. X- ray diffraction and X- ray photoelectron spectroscopy analyses showed that these films consist of metallic Pt particles dispersed in an oxide matrix. Cyclic voltammetry in acid solutions showed that the sol- gel prepared layers have relatively high Pt surface areas. The electrocatalytic activity of these materials toward the anodic oxidation of formaldehyde and methanol was compared in terms of onset potential and current density and was found to follow the sequence: Pt- Ru0.5Ir0.5O2/ Ti > Pt- RuO2/ Ti > Pt- IrO2/ Ti.
What should an ASP solver output? : a multiple position paper (2007)

Abstract. This position paper raises some issues regarding the output of solvers for Answer Set Programming and discusses experiences made in several different settings. The first set of issues was raised in the context of the first ASP system competition, which led to a first suggestion for a standardised yet miniature output format. We then turn to experiences made in related fields, like Satisfiability Checking, and finally adopt an application point of view by investigating interface issues both with simple tools and in the context of the Semantic Web and query answering. 1
Analyzing the Effectiveness of a Frame-Level Redundancy Scrubbing Technique for SRAM-based FPGAs (2015)

Radiation effects such as soft errors are the major threat to the reliability of SRAM-based FPGAs. This work analyzes the effectiveness in correcting soft errors of a novel scrubbing technique using internal frame redundancy called Frame-level Redundancy Scrubbing (FLR-scrubbing). This correction technique can be implemented in a coarse grain TMR design. The FLR-scrubbing technique was implemented on a mid-size Xilinx Virtex-5 FPGA device used as a case study. The FLR-scrubbing technique was tested under neutron radiation and fault injection. Implementation results demonstrated minimum area and energy consumption overhead when compared to other techniques. The time to repair the fault is also improved by using the Internal Configuration Access Port (ICAP). Neutron radiation test results demonstrated that the proposed technique is suitable for correcting accumulated SEUs and MBUs.
A microflow cytometer exploited for the immunological differentiation of leukocytes (2011)

In this article, we demonstrate the potential of a microfluidic chip for the differentiation of immunologically stained blood cells. To this end, white blood cells stained with antibodies typically applied for the determination of the immune status were measured in the micro-device. Relative concentrations of lymphocytes and subpopulations of lymphocytes are compared to those obtained with a conventional flow cytometer. The stability of the hydrodynamic focusing and the optical setup was determined by measuring the variation of the signal pulse height of fluorescence calibration beads, being about 2% for the micro-device. This value and the overall performance of the micro-device are similar to conventional flow cytometers. It follows from our results that such microfluidic structures are well suited as modules in a compact, portable read-out instrument. The production process of the microflow cytometers, which we exploited for immunological cell differentiation, is compatible with mass production technology like injection molding and, hence, low cost disposable chips could be available in the future.
