Design and Implementation of a Neural Network Aided Self-Interference Cancellation Scheme for Full-Duplex Radios (2018)

In-band full-duplex systems are able to transmit and receive information simultaneously on the same frequency band. Due to the strong self-interference caused by the transmitter to its own receiver, the use of non-linear digital self-interference cancellation is essential. In this work, we present a hardware architecture for a neural network based non-linear self-interference canceller and we compare it with our own hardware implementation of a conventional polynomial based canceller. We show that, for the same cancellation performance, the neural network canceller has a significantly higher throughput and requires fewer hardware resources.

Pharmacologic approaches to protection against radiation-induced lethality and other damage. (1997)

Studies on mechanisms of radioprotection are leading to a more rational use of protectors for different applications. In considering the feasibility of radioprotectors that act through various mechanisms, it is necessary to distinguish the application needed, e.g., protection against accidental external or internal exposures, acute high-dose radiation injury or low doses over a long period, high-LET radiation exposures during space flight, and protection of normal tissues of cancer patients who are undergoing therapy. Protectors generally are classified as either sulfhydryl compounds, other antioxidants, or receptor-mediated agents (e.g., bioactive lipids, cytokines, and growth factors). This review focuses on comparative radioprotection and toxicity studies in mice using the most effective phosphorothioate agents designated as WR-compounds and other classes of protectors. The superiority of phosphorothioates (WR-2721, WR-151327) as radioprotectors appears to be related to their high affinity for DNA and the similarity in structure of phosphorothioate metabolites to polyamines, and their effects on processes related to DNA structure and synthesis. Drug tolerance levels are available from clinical trials using WR-2721 (amifostine) and provide a basis for discussions of the disadvantages of phosphorothioate administration outside a clinical setting. In this regard, arguments are presented against the current use of WR-2721 by Department of Energy personnel for planned radiation exposures during emergencies. Future research may demonstrate, however, that pharmacologic agents could be useful in accident scenarios, especially when used in combination with therapeutic measures. Assessment of potential prophylactic measures should consider compatibility with therapeutic measures currently in use or ones that might be available in the future for the treatment of radiation injuries. These include antiemetics, purified stem cells, granulocyte colony-stimulating factor, and other cytokines. Their potential usefulness against radiation-induced mutagenesis of pre- and postexposure administration of phosphorothioates and other classes of protectors should be corroborated in humans.
Effect of L-Aspartic Acid and L-Glutamic Acid on Production of L-Proline (1972)

To elucidate the effect of aspartic acid on growth of Kurthia catenaforma during the proline fermentation, this organism was compared with other bacteria with respect to the rate of consumption of aspartic acid, and to the activities of enzymes concerned in the metabolism of aspartic acid. Although no marked difference in enzyme activities was observed, the aspartic acid consumption rate of K. catenaforma was markedly higher than that of other organisms. The consumption of glutamic acid by K. catenaforma was not detected at 24 hr of culture. The difference between the consumption of aspartic acid and glutamic acid in this strain might result from a difference in permeability to the amino acids. We considered that L-glutamic acid might substitute for L-aspartic acid if the uptake of glutamic acid could be increased. A number of detergents were screened for their effect on consumption of glutamic acid. Cetyltrimethylammonium bromide, sodium laurylphosphate, and polyoxyethylene sorbitan monolaurate were found to increase the transport rate of glutamic acid, but not of aspartic acid. A method of producing L-proline from glutamic acid was established with the aid of detergents.
Toward Unification of Synthesis and Verification in Topologically Constrained Logic Design (2015)

In logic synthesis, the search space is infinite in the sense that any number of gates can be connected using any topology to come up with the best circuit under performance and other constraints. In formal verification, to achieve full coverage, an n-input circuit must be checked either explicitly or implicitly using the complete set of 2 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</sup> input values. There are, however, situations when the possible circuit topologies are limited. Logic optimization methods, in general, do not change circuit topologies dramatically. Most of them are based on series of local circuit transformations. In this paper, we discuss formal verification of circuits produced by logic synthesis where the search space is limited, and only gates or subcircuits are transformed whereas their interconnections never change. If there are p possible transformations for each gate or subcircuit, and there are m gates or subcircuits in the entire circuit, the number of all possible transformations for the entire circuit is p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sup> . Logic synthesis with this restriction attempts to find the best circuit among the p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sup> alternatives. The logic synthesis problem can be formulated as a sequence of incremental SAT problems and the complete set of test patterns can be computed, which detects all possible errors in the synthesized circuit. As long as the search space is limited to the p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</sup> alternatives, such complete set of test patterns can be used for formal verification. The number of test patterns needed in this case is experimentally shown to be very small, e.g., a few hundred, even for circuits having several hundred inputs and several thousand gates. With the complete set of test patterns generated for the circuit transformations, logic synthesis and formal verification are unified in the sense that the small number of test patterns allows for logic synthesis with 100% correctness.
Simulations of host–plasmid interactions in <i>Escherichia coli</i>: Copy number, promoter strength, and ribosome binding site strength effects on metabolic activity and plasmid gene expression (1987)

A mechanistically detailed single-cell model E. coli B/r-A was adapted to simulate the effects of vector presence on cell metabolism. Competition for RNA polymerase between chromosome and plasmid DNA is explicitly included. Distribution of active ribosomes among chromosome- and plasmid-derived messenger RNA, another key facet of host-plasmid interactions, is also treated in detail. Simulations of recombinant cell growth rate and cloned-gene productivity as a function of relative plasmid number per cell agree closely with experimental results. Model prediction of the variation of cell cycle parameters C and D with plasmid number are roughly consistent with available data. Models of this class can be used to simulate changes in productivity resulting from specific alterations in the expression vector. The effects of changing cloned-gene promoter and ribosome binding strengths and of augmenting cell transcription or translation capacity have been studied using the recombinant cell model. Results suggest that cloned-gene expression is limited by cellular transcription capacity. These and other parametric studies, conveniently implemented using the computer cell, provide important guidance for future experiments directed at better understanding of host-plasmid interactions and at optimizing recombinant system productivity.
Dual Leucine Zipper Kinase as a Therapeutic Target for Neurodegenerative Conditions (2013)

Dual leucine zipper kinase (DLK) is a serine/threonine protein kinase that is a member of the mixed lineage kinase subfamily. Mixed lineage kinases are upstream MAP3Ks that activate the JNK pathway. DLK is primarily responsible for activating JNK and mediating the apoptotic stress response in various cell types, specifically neurons. Inhibition and knockdown of DLK has been demonstrated to have neuroprotective effects in cellular and animal models of Alzheimer's disease, glaucoma, Parkinson's disease and other neurodegenerative conditions. Several series of ATP-binding site inhibitors have been identified through profiling efforts providing launch points for future medicinal chemistry programs.

Statistical construction of a representative CAD model from a measured population for RF design applications (2002)

Component models available in CAD software do not consider statistical variation and layout or package parasitic effects of components. Because of the complexity of device packages, EM simulation can only be used to analyze relatively simple circuits. In this paper, we present a methodology to statistically construct a representative SMD component model from a measured population, and show how such a model can be used in a circuit simulator for effective first-pass design, which incorporates all the parasitic effects through measurements. Using measured component data in optimization and yield analysis is expected to enable CAD packages to reduce considerably the number of design cycles.
Synthesis of 6-cyano- and 5-cyano-uridines and their derivatives Nucleosides and nucleotides. XXI. (1978)

5'-O-Acetyl-2', 3'-O-isopropylidene-5-bromouridine (1) gave the 6-cyanouridine (2) by treatment with sodium cyanide at room temperature. Heating of 2 with sodium cyanide afforded the 5-cyanouridine derivative (3) by the addition-elimination mechanism. This method provides a convenient route of the preparation of 5-cyanouridine and 5-cyano-2'-deoxyuridine. The cyano function of 2 was converted to the amide, thioamide, carboxyl, hydroxymethyl, chloromethyl, methyl, cyanomethyl, and carboxymethyl group, respectively. The circular dichroism (CD) spectra of 6-substituted uridines prepared in this work showed all positive CD bands, though existed mainly as the syn-form as determined by the nuclear magnetic resonance measurements.

The outer andinner diameters of the tubules can be controlled by varying the time allowed for the polymerization of acrylonitrile within the pores of a nanotubes formed in the pores are subsequently graphitized at high temperatures to form the graphitized nanotubes magnified image .
Identification of a Putative <i>Salmonella enterica</i> Serotype Typhimurium Host Range Factor with Homology to IpaH and YopM by Signature-Tagged Mutagenesis (1999)

The genetic basis for the host adaptation of Salmonella serotypes is currently unknown. We have explored a new strategy to identify Salmonella enterica serotype Typhimurium (S. typhimurium) genes involved in host adaptation, by comparing the virulence of 260 randomly generated signature-tagged mutants during the oral infection of mice and calves. This screen identified four mutants, which were defective for colonization of only one of the two host species tested. One mutant, which only displayed a colonization defect during the infection of mice, was further characterized. During competitive infection experiments performed with the S. typhimurium wild type, the mutant was defective for colonization of murine Peyer's patches but colonized bovine Peyer's patches at the wild-type level. No difference in virulence between wild type and mutant was observed when calves were infected orally with 10(10) CFU/animal. In contrast, the mutant possessed a sixfold increase in 50% lethal morbidity dose when mice were infected orally. The transposon in this mutant was inserted in a 2.9-kb pathogenicity islet, which is located between uvrB and yphK on the S. typhimurium chromosome. This pathogenicity islet contained a single gene, termed slrP, with homology to ipaH of Shigella flexneri and yopM of Yersinia pestis. These data show that comparative screening of signature-tagged mutants in two animal species can be used for scanning the S. typhimurium genome for genes involved in host adaptation.
Evaluation of HER-2/<i>neu</i> Gene Amplification and Overexpression: Comparison of Frequently Used Assay Methods in a Molecularly Characterized Cohort of Breast Cancer Specimens (2002)

Based on these findings, the FISH assays were highly accurate, with immunohistochemical assays performed with R60 and 10H8 nearly as accurate. The DAKO HercepTest and the Ventana CB11 immunohistochemical assay were statistically significantly different from the Vysis FISH assay in evaluating these previously molecularly characterized breast cancer specimens.
[A quantitative approach to understand the ultramicro-structure responsible for input mechanism in excitation-contraction (E-C) coupling, on the basis of physio-morphological observations]. (1992)

Our morphophysiological studies using concanavalin A-ferritin (Con A-F) have indicated that: (1) an out- and up-ward movement of a movable structure at the luminal surface-portion of the T-tubular membrane opposite the feet initiates contraction; (2) the grade of the movement depends on that of depolarization; (3) the movable structure is essentially a 'moving arm', which is fixed in wall of T-tubules at its fixed end and is able to be bound to the Con A-moiety of Con A-F particle about at its free end. Calculation based on molecular morphology and behaviour of Con A-F particle revealed following points: If (a) the origin of coordinate be the intersection of longitudinal center line of foot and the surface of T-tubular membrane in the transverse section of the tubules, (b) the fixed point of the arm is exactly on the surface of T-tubular membrane, and (c) the movement takes place in the transverse direction to the longitudinal axis of T-tubules, (1) the location of the center point of the movement of the moving arm is at 5.4 nm in the outside direction from the origin, (2) the arm is about 4 nm in length and moves by about 2.4 nm up- and out-ward at its free end upon about complete depolarization.
Sample-driven schema mapping (2012)

End-users increasingly find the need to perform light-weight, customized schema mapping. State-of-the-art tools provide powerful functions to generate schema mappings, but they usually require an in-depth understanding of the semantics of multiple schemas and their correspondences, and are thus not suitable for users who are technically unsophisticated or when a large number of mappings must be performed.
Implementation of wind performance studies for large antenna structures (1977)

Structural design procedures are described for a large antenna system to meet performance requirements under gravity and wind loading. A computational method is shown for the evaluation of performance in response to wind loading. Cumulative probability distribution curves for wind loading gain reductions for 100-m-diameter antennas are developed to compare a relatively heavy baseline reflector backup structure with two lighter-weight structures; all have equivalent, acceptable performance for gravity loading.
Intracerebroventricular angiotensin II‐induced thirst and sodium appetite in rat are blocked by the AT1 receptor antagonist, Losartan (DuP 753), but not by the AT2 antagonist, CGP 42112B (1992)

In the rat, intakes of water and 1.8% NaCl induced by I.C.V. angiotensin II were inhibited by prior I.C.V. injection of the angiotensin subtype 1 receptor antagonist, Losartan, but not by the subtype 2 receptor antagonist, CGP 42112B. Drinking induced by I.C.V. carbachol was unaffected by either antagonist.
Creatine enhances survival of glutamate‐treated neuronal/glial cells, modulates Ras/NF‐κB signaling, and increases the generation of reactive oxygen species (2004)

The protective effects of creatine against glutamate cytotoxicity have been demonstrated in neuronal cells and animal models of neurodegenerative diseases. The mechanisms underlying creatine neuroprotection against glutamate-induced cell death are understood poorly. For the first time, we demonstrate a correlation between the protective effect of creatine and the modulation of Ras-mediated redox-dependent signaling pathways, which involve nuclear factor kappaB (NF-kappaB) and reactive oxygen species (ROS). In primary cerebrocortical cultures of mixed neurons and glia, creatine significantly reduced glutamate-induced cell death. The increase in cell survival was accompanied by increased generation of oxygen radicals and decreased levels of farnesylated Ras and IkappaB, an inhibitor of NF-kappaB. Non-farnesylated Ras and ROS-dependent activation of NF-kappaB have been shown to promote neuronal survival. Our data suggest that creatine may enhance survival signaling via activation of the Ras/NF-kappaB system. Possible mechanisms underlying the protective effect of creatine are discussed, including normalization of cellular GTP levels.

Novel spot size converter for coupling standard single mode fibers to SOI waveguides (2016)

We have designed and numerically simulated a novel spot size converter for coupling standard single mode fibers with 10.4μm mode field diameter to 500nm × 220nm SOI waveguides. Simulations based on the eigenmode expansion method show a coupling loss of 0.4dB at 1550nm for the TE mode at perfect alignment. The alignment tolerance on the plane normal to the fiber axis is evaluated at ±2.2μm for ≤1dB excess loss, which is comparable to the alignment tolerance between two butt-coupled standard single mode fibers. The converter is based on a cross-like arrangement of SiO<sub>x</sub>N<sub>y</sub> waveguides immersed in a 12μm-thick SiO<sub>2</sub> cladding region deposited on top of the SOI chip. The waveguides are designed to collectively support a single degenerate mode for TE and TM polarizations. This guided mode features a large overlap to the LP01 mode of standard telecom fibers. Along the spot size converter length (450μm), the mode is first gradually confined in a single SiO<sub>x</sub>N<sub>y</sub> waveguide by tapering its width. Then, the mode is adiabatically coupled to a SOI waveguide underneath the structure through a SOI inverted taper. The shapes of SiO<sub>x</sub>N<sub>y</sub> and SOI tapers are optimized to minimize coupling loss and structure length, and to ensure adiabatic mode evolution along the structure, thus improving the design robustness to fabrication process errors. A tolerance analysis based on conservative microfabrication capabilities suggests that coupling loss penalty from fabrication errors can be maintained below 0.3dB. The proposed spot size converter is fully compliant to industry standard microfabrication processes available at INO.

Two-colour strong-field ionization and dissociation of H2 using 780 and 390 nm femtosecond pulses (1996)

Abstract We report the observation of a substantial enhancement in H2 + and H+ ion production when the two-colour (780 and 390 nm) pulses are superposed. A strong dependence of ion yield on the relative directions of the polarization of the two fields is observed. The experimental results are discussed and compared with existing theoretical calculations.
Work-based performance measurement and analysis of virtual heterogeneous machines (1997)

Abstract Presented here is a set of methods and tools developed to provide transportable measurements of performance in heterogeneous networks of machines operating together as a single virtual heterogeneous machine (VHM). The methods are work-based rather than time-based, and yield significant analytic information. A technique for normalizing the measure of useful work performed across a heterogeneous network is proposed and the reasons for using a normalized measure are explored. It is shown that work-based performance measures are better than time-based ones because they may be (1) taken while a task is currently executing on a machine; (2) taken without interrupting production operation of the machine network; (3) used to compare disparate tasks, and (4) used to perform second-order analysis of machine network operation. This set of performance tools has been used to monitor the utilization of high-performance computing networks, provide feedback on algorithm design and determine the veracity of computing performance models.
