Experimental Evidence for Spin-Orbit Interactions in Positronium-Xe Collisions (2006)

Spin-orbit interaction of positronium (Ps) with the surrounding atoms, predicted by Mitroy and Novikov [Phys. Rev. Lett. 90, 183202 (2003)], has been detected experimentally. We have found that the lifetime of the magnetically unperturbed ortho-Ps in Xe gas of 1 atm decreases significantly when a magnetic field of 1.0 T is applied. This decrease is attributed to the Ps spin conversion caused by spin-orbit interaction during Ps-Xe collision. The annihilation cross section of ortho-Ps due to this interaction has been determined to be 3 times as large as that expected by Mitroy and Novikov.
Enterococcus faecium ST17 from Coastal Marine Sediment Carrying Transferable Multidrug Resistance Plasmids (2016)

The multidrug-resistant Enterococcus faecium 17i48, sequence type 17, from marine sediment, carrying erm(B), tet(M), and tet(L) genes, was analyzed for the presence of antibiotic resistance plasmids and for the ability to transfer resistance genes. The strain was found to harbor the replicon type (repA) of pRE25, pRUM, pHTβ, and the axe-txe toxin-antitoxin (TA) system. In mating experiments, tet(M) and tet(L) were cotransferred with the repA<sub>pRE25</sub>, whereas erm(B) was consistently cotransferred with the axe-txe and repA<sub>pRUM</sub>, suggesting that tetracycline and erythromycin resistance genes were carried on different elements both transferable by conjugation, likely via pHTβ-mediated mobilization. Hybridization and PCR mapping demonstrated that tet(M) and tet(L) were located in tandem on a pDO1-like plasmid that also carried the repA<sub>pRE25</sub>, whereas erm(B) was carried by a pRUM-like plasmid. Sequencing of the latter plasmid showed a high nucleotide identity with pRUM and the presence of cat, aadE, sat4, and a complete aphA resistance genes. These findings show that the genetic features of E. faecium 17i48 are consistent with a hospital-adapted clone and suggest that antibiotic resistance may spread in the environment, also in the absence of antibiotic pressure, due to TA system plasmid maintenance.
Technical Report: Observability with Random Observations (2012)

Recovery of the initial state of a high-dimensional system can require a large number of measurements. In this paper, we explain how this burden can be significantly reduced when randomized measurement operators are employed. Our work builds upon recent results from Compressive Sensing (CS). In particular, we make the connection to CS analysis for random block diagonal matrices. By deriving Concentration of Measure (CoM) inequalities, we show that the observability matrix satisfies the Restricted Isometry Property (RIP) (a sufficient condition for stable recovery of sparse vectors) under certain conditions on the state transition matrix. For example, we show that if the state transition matrix is unitary, and if independent, randomly-populated measurement matrices are employed, then it is possible to uniquely recover a sparse high-dimensional initial state when the total number of measurements scales linearly in the sparsity level (the number of non-zero entries) of the initial state and logarithmically in the state dimension. We further extend our RIP analysis for scaled unitary and symmetric state transition matrices. We support our analysis with a case study of a two-dimensional diffusion process.

A Game Theoretic Model for the Multiperiodic Smart Grid Demand Response Problem (2019)

Today's smart grid faces many challenges due to the rapid evolution of generation, distribution, and storage means which enable users to produce, store, and sell energy back to the providers. Demand response management plays a key role in achieving the objective of balancing electricity supply and demand efficiently. It also helps leveling consumption during peak hours. To do so, this paper proposes a game theoretic model for the multiperiodic smart grid demand side management problem with shifted demand. The proposed model has two major sets of players: Homeowners and electricity providers. We develop a 0-1 mixed linear programming approach to compute the Nash equilibria of the proposed game. We analyze the structure of the Nash equilibria to maintain the viability of the smart grid infrastructure. We also discuss the order relations between the users and the providers utility coefficients. Finally, we conduct extensive experiments on smart grid demand response synthetic data with different size. The obtained results demonstrate the scalability of the proposed game model.
Electrochemical and Spectroscopic Studies of Europium(II/III) Species in a Hydrophobic Room-Temperature Ionic Liquid (2009)

The electrochemical and spectroscopic properties of divalent and trivalent europium species have been investigated in a hydrophobic room-temperature ionic liquid, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (BMPTFSA). The diffusion coefficients of Eu(II) and Eu(III) estimated by chronoamperometry were (3.9±0.4)×10−8 and (4.2±0.7)×10−8 cm2 s−1, respectively. The diffusion of Eu(II) is affected by the coordination between Eu(II) and TFSA−. The TFSA− ligand seems to act as a weaker ligand than CH3OH according to the splitting of the 5d levels observed from the absorption spectrum for Eu(II). The emission spectra of Eu(II) and Eu(III) were also obtained in BMPTFSA.

Higher visibility for LEDs (1994)

The gradually evolving technology of light-emitting diodes has of late made a quantum leap. These semiconductor devices are usurping some of the slots that, till now, had been filled by incandescent lamps and cathode ray tubes. The author describes how the luminance and luminous effiency of light-emitting diodes (LEDs) in the last few years have reached such high levels that they can replace incandescent lamps in running lights on trucks. Particularly where safety is involved, the longer life and inherent ruggedness of the solid-state devices make them a highly desirable substitute; the lower maintenance cost of the LEDs is a boon to any application.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Articulatory features for "meeting" speech recognition (2006)

“Meeting” speech, for example from the RT-04S task, contains a mixture of different speaking styles that leads to word error rates higher than 25% even when close-talking microphones are being used. The problem is even more serious, as word error rates are particularly high when speakers use a clear speaking mode, for example because they want to stress an important point. Previous work showed that an approach that combines standard phonebased acoustic models with models detecting the presence or absence of “Articulatory Features” such as “Rounded” or “Voiced” can improve ASR performance particularly for these cases. This paper presents a discriminative approach to automatically computing from training or adaptation data the feature stream weights needed for the above approach, therefore presenting a framework for integrating articulatory features into existing automatic speech recognition systems. We find a 7% relative improvements on top of our best RT-04S system using discriminative adaptation.
The Influence of Cutting Edge Deformations on Magnetic Performance Degradation of Electrical Steel (2015)

Although it has been widely known that the cutting process of electrical steel brings deterioration effects to magnetic properties, it is still unclear how to evaluate the quality of the cutting process effectively. This paper investigates the performance degradation due to the punching process based on a needle probe instrument that incorporates three needle probes arranged in a way to pick up the flux around the area of the cutting edge and the flux of the unaffected center area. The amount of performance degradation can be obtained by comparing the edge and the center flux values. 50CS1300 samples with different punching clearances were produced, and measurement results were demonstrated. The power conversion losses imposed by the punching process were evaluated in terms of several measured parameters, including the magnetic flux density, the iron loss, and the copper loss. In addition, how different grain sizes affect the punching performance is also studied in this paper. Two materials with the same iron loss grade but different grain sizes were punched, and their magnetic properties were also examined.
Interaction of the tyrosine phosphatase SHP-2 with Gab2 regulates Rho-dependent activation of the c-fosserum response element by interleukin-2 (2004)

Gab2 (Grb2-associated binder-2), a member of the IRS (insulin receptor substrate)/Gab family of adapter proteins, undergoes tyrosine phosphorylation in response to cytokine or growth factor stimulation and serves as a docking platform for many signal transduction effectors, including the tyrosine phosphatase SHP-2 [SH2 (Src homology 2)-domain-containing tyrosine phosphatase]. Here, we report that, following IL-2 (interleukin-2) stimulation of human T lymphocytes, SHP-2 binds tyrosine residues 614 and 643 of human Gab2 through its N- and C-terminal SH2 domains respectively. However, the sole mutation of Tyr-614 into phenylalanine is sufficient to prevent Gab2 from recruiting SHP-2. Expression of the Gab2 Tyr-614-->Phe (Y614F) mutant, defective in SHP-2 association, prevents ERK (extracellular-signal-regulated kinase) activation and expression of a luciferase reporter plasmid driven by the c-fos SRE (serum response element), indicating that interaction of SHP-2 with Gab2 is required for ERK activation in response to IL-2. Further investigation of IL-2-dependent induction of SRE showed that expression of a constitutively active mutant of the RhoA GTPase synergizes with IL-2 for SRE-driven transcription, whereas a dominant-negative mutant reduces the IL-2 response. Thus, in response to IL-2, full induction of the SRE requires ERK-dependent as well as Rho-dependent signals that target the Ets-box and the CArG-box respectively. We also report that the synergy between Gab2/SHP-2 and RhoA for IL-2-dependent CArG-box-driven transcription depends upon MEK (mitogen-activated protein kinase/ERK kinase) activation, and is likely to involve regulation of the serum response factor co-activator MAL. Our studies thus provide new insights into the role of Gab2 and SHP-2 in IL-2 signal transduction.

Gastrointestinal Behavior of Orally Administered Radiolabeled Erythromycin Pellets in Man as Determined by Gamma Scintigraphy (1990)

The behavior of single 250-mg doses of a multiparticulate form of erythromycin base (ERYC(R)), each including five pellets radiolabeled with neutron-activated samarium-153, was observed by gamma scintigraphy in seven male subjects under fasting and nonfasting conditions. The residence time and locus of radiolabeled pellets within regions of the gastrointestinal tract were determined and were correlated with plasma concentrations of erythromycin at coincident time points. Administration of food 30 minutes postdosing reduced fasting plasma erythromycin Cmax and area under the plasma erythromycin versus time curve (AUC) values by 43% and 54%, respectively. Mean peak plasma concentration of erythromycin (Cmax) in the fasting state was 1.64 micrograms/mL versus 0.94 micrograms/mL in the nonfasting state. Total oral bioavailability, as determined by mean AUC (0-infinity) of the plasma erythromycin concentration versus time curve, was 7.6 hr/micrograms/mL in the fasted state, versus 3.5 hr/micrograms/mL in the nonfasting state. Mean time to peak plasma erythromycin concentration (tmax) in the fasting state was 3.3 hours, versus 2.3 hours in the nonfasting state. Plasma concentrations of erythromycin in both fasting and nonfasting states were within acceptable therapeutic ranges. Evidence provided by this study: 1) indicates that pellet erosion and absorption of active erythromycin base begins when the enteric-coated pellets reach the highly vascular mucosa of the jejunum and proximal ileum, and is essentially completed within the ileum, with a significant portion absorbed in the medial-to-distal ileum; 2) confirms that acceptable therapeutic plasma levels of erythromycin are attained in nonfasting subjects (Cmax = 0.94 microgram/mL) and that superior plasma erythromycin concentrations (Cmax = 1.64 micrograms/mL) are achieved by administration of the dose on an empty stomach 1 to 2 hours before or after meals; 3) corroborates other comparative studies reporting greater fasting bioavailability with this multiparticulate dosage form of erythromycin base than with reference single tablet or particle-in-tablet formulations; and 4) indicates that neutron activation of stable isotopes incorporated as a normal excipient in industrially-produced formulations provides an effective means for in vivo evaluation of dosage forms through gamma scintigraphy.

Desorption electrospray ionization is applied to the mass spectrometric profiling of phospholipids. In their Communication on page 7094 ff., R. G. Cooks, R. M. Caprioli, and co‐workers report the rapid analysis of untreated biological tissues, including the tumor region of liver tissue. The impact of charged liquid microdroplets on liver tissue in air and the release of lipids and other molecules as ions for analysis is illustrated in the cover picture (prepared by Z. Ouyang, J. Wiseman, and R. Shreve).
Absorbing boundary conditions for wave-equation migration (1980)

Abstract The standard boundary conditions used at the sides of a seismic section in wave-equation migration generate artificial reflections. These reflections from the edges of the computational grid appear as artifacts in the final section. Padding the section with zero traces on either side adds to the cost of migration and simply delays the inevitable reflections.We develop stable absorbing boundary conditions that annihilate almost all of the artificial reflections. This is demonstrated analytically and with synthetic examples. The absorbing boundary conditions presented can be used with any of the different types of finite-difference wave-equation migration, at essentially no extra cost.
SUIF Explorer (1999)

The SUIF Explorer is an interactive parallelization tool that is more effective than previous systems in minimizing the number of lines of code that require programmer assistance. First, the interprocedural analyses in the SUIF system is successful in parallelizing many coarse-grain loops, thus minimizing the number of spurious dependences requiring attention. Second, the system uses dynamic execution analyzers to identify those important loops that are likely to be parallelizable. Third, the SUIF Explorer is the first to apply program slicing to aid programmers in interactive parallelization. The system guides the programmer in the parallelization process using a set of sophisticated visualization techniques.This paper demonstrates the effectiveness of the SUIF Explorer with three case studies. The programmer was able to speed up all three programs by examining only a small fraction of the program and privatizing a few variables.
Application of power ultrasound to cementitious materials: Advances, issues and perspectives (2018)

Novel techniques such as power ultrasound (PUS) are currently under consideration to improve the hydration of cementitious materials and to promote the effectiveness of replacing supplementary cementitious materials; SCMs, in terms of mechanical, microstructural and transport properties. This could enhance the properties of cementitious composites, reduce the quantity of waste materials, as well as decreasing the CO2 footprint of cementitious materials. A handful of studies have investigated this promising field and little is known about the mechanisms by which the ultrasound acts in cement-based systems. This paper outlines the possible mechanisms involved on the effects of PUS as a method to promote cement hydration kinetics of Portland cement and binary blends. It also reviews and analyses previous research conducted mostly on the dispersing effects of PUS on the enhancement of pozzolanic reactivity of SCMs in cementitious systems. This review concludes with some perspectives on research needed to gain a fundamental understanding of this emerging field.

Propagation of cells expressing donor phenotype (MHC class I, II and Y-chromosome) from the bone marrow of murine liver allograft recipients in response to GM-CSF in vitro. (1995)

An unresolved issue with the recent demonstration of persistent low-level donor leukocyte chimerism following organ transplantation1,2 has been the means by which the chimeric cells can perpetuate themselves for long periods postoperatively. This question was addressed in mice by transplantation without immunosuppression across MHC class I-II and mHC disparities using a strain combination (B10→C3H) that permits permanent acceptance of the liver, but not other allogeneic organs.3 A method used previously to propagate dendritic cell progenitors from normal mouse spleen or liver4 was implemented to ascertain whether, in addition to host-derived cells, cells of donor phenotype could be propagated from the lymphoid tissue (bone marrow and spleen) of liver-transplant recipients. For comparative purposes, similar techniques were applied to cells propagated from the lymphoid tissues of unmodified C3H mice that rejected cardiac allografts from the same donor strain.
Context-Aware Mobile Collaborative Systems: Conceptual Modeling and Case Study (2012)

A Mobile Collaborative System (MCOS) enable the cooperation of the members of a team to achieve a common goal by using a combination of mobile and fixed technologies. MCOS can be enhanced if the context of the group of users is considered in the execution of activities. This paper proposes a novel model for Context-Aware Mobile COllaborative Systems (CAMCOS) and a functional architecture based on that model. In order to validate both the model and the architecture, a prototype system in the tourism domain was implemented and evaluated.
Cell differentiation and apoptosis of monocytic and promyelocytic leukemia cells (U‐937 and HL‐60) by tryptanthrin, an active ingredient of Polygonum tinctorium Lour. (2001)

Tryptanthrin, a bioactive ingredient of Polygonum tinctorium Lour., is a member of the Indigo plant family and has potent cytocidal effects on various human leukemia cells in vitro. At low concentrations, tryptanthrin enhanced the expression of cell differentiation (CD) markers in human monocytic (U-937) and promyelocytic (HL-60) leukemia cells indicative of differentiation to monocytes/macrophages. Furthermore, nitroblue tetrazolium (NBT) reductive and alpha-naphthyl butyrate esterase (NBE) activities were markedly increased after treatment. Tryptanthrin was more potent than dimethyl sulfoxide (DMSO) at inducing U-937 cell differentiation into monocytes/macrophages. After treatment with higher concentrations of tryptanthrin for 24 h, cytoplasmic vacuolation and destruction of mitochondria were observed. The leukemia cells died via apoptosis 48 h after treatment. Cytoplasmic vacuolation and apoptotic changes correlated with the dysfunction of mitochondria. Electron microscopic observations revealed marked swelling and destruction of mitochondria after exposure of the leukemia cells to tryptanthrin. Exposure to tryptanthrin enhanced Fas-induced apoptosis and increased caspase-3 activity before induction of apoptosis. These results show that low concentrations of tryptanthrin can induce differentiation of leukemia cells but higher concentrations will kill leukemia cells through apoptosis, possibly through a caspase-3/Fas antigen pathway.
