Reducing Power, Leakage, and Area of Standard-Cell ASICs Using Threshold Logic Flip-Flops (2016)

In this paper, we describe a new approach to reduce dynamic power, leakage, and area of application-specified integrated circuits, without sacrificing performance. The approach is based on a design of threshold logic gates (TLGs) and their seamless integration with conventional standard-cell design flow. We first describe a new robust, standard-cell library of configurable circuits for implementing threshold functions. Abstractly, the threshold gate behaves as a multi-input, single-output, edge-triggered flip-flop, which computes a threshold function of the inputs on the clock edge. The library consists of a small number of cells, each of which can compute a set of complex threshold functions, which would otherwise require a multilevel network. The function realized by a given threshold gate is determined by how signals are mapped to its inputs. We present a method for the assignment of signals to the inputs of a threshold gate to realize a given threshold function. Next, we present an algorithm that replaces a subset of flip-flops and portions of their logic cones in a conventional logic netlist, with threshold gates from the library. The resulting circuits, with both conventional and TLGs (called hybrid circuits), are placed and routed using commercial tools. We demonstrate significant reductions (using postlayout simulations) in power, leakage, and area of the hybrid circuits when compared with the conventional logic circuits, when both are operated at the maximum possible frequency of the conventional design.
Role of <i>Porphyromonas gingivalis</i> Phosphoserine Phosphatase Enzyme SerB in Inflammation, Immune Response, and Induction of Alveolar Bone Resorption in Rats (2010)

Porphyromonas gingivalis secretes a serine phosphatase enzyme, SerB, upon contact with gingival epithelial cells in vitro. The SerB protein plays a critical role in internalization and survival of the organism in epithelial cells. SerB is also responsible for the inhibition of interleukin-8 (IL-8) secretion from gingival epithelial cells infected with P. gingivalis. This study examined the ability of a P. gingivalis SerB mutant to colonize the oral cavity and induce gingival inflammation, immune responses, and alveolar bone resorption in a rat model of periodontal disease. Both P. gingivalis ATCC 33277 and an isogenic ΔSerB mutant colonized the oral cavities of rats during the 12-week experimental period. Both of the strains induced significant (P < 0.05) systemic levels of immunoglobulin G (IgG) and isotypes IgG1, IgG2a, and IgG2b, indicating the involvement of both T helper type 1 (Th1) and Th2 responses to infection. Both strains induced significantly (P < 0.05) higher levels of alveolar bone resorption in infected rats than in sham-infected control rats. However, horizontal and interproximal alveolar bone resorption induced by the SerB mutant was significantly (P < 0.05) lower than that induced by the parental strain. Rats infected with the ΔSerB mutant exhibited significantly higher levels of apical migration of the junctional epithelium (P < 0.01) and polymorphonuclear neutrophil (PMN) recruitment (P < 0.001) into the gingival tissues than rats infected with the wild type. In conclusion, in a rat model of periodontal disease, the SerB phosphatase of P. gingivalis is required for maximal alveolar bone resorption, and in the absence of SerB, more PMNs are recruited into the gingival tissues.
Normal-Mode Parameters of Microstrip Coupled Lines of Unequal Width (Short Paper) (1984)

Empirical relations for the capacitive and inductive coupling coefficients have been used to compute normal-mode parameters of non-identical microstrip coupled lines. The computed values of mode velocities and mode impedances are compared with available results from the literature and experimental results on nonidentical microstrip couplers to test the applicability of the empirical relations.
Architecture of a programmable systolic array (2003)

The architecture of a simple but programmable linear systolic array tuned to support a variety of symbolic computations is presented. The system, the Brown Systolic Array (B-SYS) is currently being implemented in CMOS. B-SYS demonstrates that programmable processor arrays may be made fully systolic with no need for local program memory or global instruction broadcasting. Any hazards introduced by the systolic instruction stream can be avoided using a processing phase concept. The application of these ideas results in a basic cell that is both simple and flexible, making it possible to build massively parallel, programmable systolic arrays.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Tunable, Dielectric-Loaded Microwave Cavities Capable of High Q and High Filling Factor (1963)

Many applications require the presence of a dielectric inside a microwave resonator. This paper presents a new type of dielectric-loaded cavity and contains a detailed analysis of its properties. The cavity consists of a waveguide of arbitrary but uniform cross section, filled with dielectric for part of its length, with movable shorting plungers in the guide beyond one or both ends of the dielectric. Such a structure supports resonances at frequencies where a particular waveguide mode is above cutoff in the dielectric, but below cutoff outside. These resonances can have high Q's, especially when the cavity ends are open. Frequency tuning is possible via the movable plungers. The present analysis investigates resonant frequency, tuning range, and electric and magnetic filling factors. Wall losses are calculated for the particular case of a circular cross section. All results are plotted as universal design curves. The results indicate that this configuration is quite versatile and should be useful in numerous applications, including microwave solid-state masers, microwave light modulators, and the study of "ghost mode" resonances in waveguide windows.
A Five-Membered Enantiopure Cyclic Nitrone from Malic Acid by Regioselective Oxidation of Cyclic Hydroxylamine. Synthesis of (1S,7S,8aR)-Octahydro-1,7-dihydroxyindolizine (1995)

The chiral optically pure five-membered 3-tert-butoxy-1-pyrroline N-oxide (1) was synthesized by\na convenient five-step procedure from diethyl L-malate. The key step is the regioselective HgO\ndehydrogenation of the N-hydroxypyrrolidine 6 obtained by double-nucleophilic displacement of a\n(bis)mesylate with hydroxylamine. A rationalization of the observed regioselectivity of the oxidation\nby studying the oxidation of a deuterated N-hydroxypyrrolidine 20 is reported. Nitrone 1 has been\napplied to the synthesis of a new (lS,7S,8aR)-1,7-dihydroxyindolizidin(e2 8) via 1,3-dipolar\ncycloaddition strategies.
Combining stereo and visual hull information for on-line reconstruction and rendering of dynamic scenes (2004)

In this paper, we present a novel system which, combines depth-from-stereo and visual hull reconstruction for acquiring dynamic real-world scenes at interactive rates. First, we use the silhouettes from multiple views to construct a polyhedral visual hull is then used to limit the disparity range during depth-from-stereo computation. The restricted search range improves both speed and quality of the stereo reconstruction. In return, stereo information can compensate for some of the visual hull method, such as inability to reconstruct surface details and concave regions. Our system achieves a reconstruction frame rate of 4fps.
Simulation Results of Shannon Entropy based Flexgrid Routing and Spectrum Assignment on a Real Network Topology (2013)

We present a novel RSA algorithm that uses a quantitative fragmentation metric using the concept of Shannon entropy in Flexgrid networks. By applying this metric to a representative network, support for almost 10% more demands in a static growth scenario is shown.
CNBP controls tumor cell biology by regulating tumor‐promoting gene expression (2019)

Cellular nucleic acid-binding protein (CNBP) is associated with cell proliferation, and its expression is elevated in human tumors, but the molecular mechanisms of CNBP in tumor cell biology have not been fully elucidated. In this study, we report that CNBP is a transcription factor essential for regulating matrix metalloproteinases mmp-2, mmp-14, and transcription factor e2f2 gene expression by binding to their promoter regions via a sequence-specific manner. Importantly, epidermal growth factor stimulation is required to induce CNBP phosphorylation and nuclear transport, thereby promoting the expression of mmp-2, mmp-14, and e2f2 genes. As a consequence, loss of cnbp attenuates the ability of tumor cell growth, invasion, and migration. Conversely, overexpression of cnbp is associated with tumor cell biology. Collectively, our findings reveal CNBP as a key transcriptional regulator of tumor-promoting target genes to control tumor cell biology.
Ewingʼs sarcoma and peripheral primitive neuroectodermal tumors after their genetic union (1998)

The Ewing family of tumors has been defined by the presence of an EWS-ets gene rearrangement. Using molecular techniques for the visualization of this aberration, several tumors of unusual location and histology were recently identified and added to this group. Increasing experimental data suggest that EWS-ets fusions act as transforming transcription factors. Subtractive screening of transgenic fibroblasts has led to the identification of potential targets. The authentic cellular context for these aberrant gene products is still unknown and may be diverse, however. Clinical heterogeneity has stimulated a search for genetic factors that may relate to treatment response. The effect of the EWS-ets fusion transcript structure on localized disease has been recently confirmed and frequent p16 tumor suppressor alterations have been described. The presence of metastases at diagnosis as the major predictor of outcome has been assessed on a submicroscopic level by reverse transcriptase-polymerase chain reaction. Problems arising from these studies are discussed, although the biological basis for variable disease extension remains obscure.
Role of Fungi in the Survival of Dermatophagoides (Acarina: Pyroglyphidae) in House-Dust Environment1 (1973)

Dermatophagoides farinae Hughes did not survive or reproduce on any of the 45 species of fungi isolated from stored grain, house dust, or human skin scales. Fungi of the genera Aspergillus and Penicillium were Isolated from the gut of laboratory bred D. pteronyssinus Trouessart. Rearing experiments showed that the culturing of Aspergillus amstelodami (A. glallcus group) on mite food medium defatted human dander and yeast greatly enhanced the development and reproduction of D. pteronysslnus. probably by digesting fatty substances from the human dander and the presence of vitamins in the yeast. It is suggested that in house dust certmn fungi play an Important role In the food chain by predigesting human dander. Members of the A. glaucus group could be easily involved because of their high drought resistance and their ability to break down fatty substances in their food medium.

Effects of adenosine on the functions of circulating polymorphonuclear leukocytes during hyperdynamic endotoxemia (1997)

Endotoxin-activated polymorphonuclear leukocytes (PMNL) adhere to the vascular endothelium and cause damage by the release of toxic superoxide anions (O2-). Because adenosine is a potent inhibitor of PMNL in vitro, the present study investigates the effects of this nucleoside on the functions of circulating PMNL in a standardized porcine model of hyperdynamic endotoxemia. Ten anesthesized pigs received an intravenous (i.v.) 330-min infusion of endotoxin (5 microg/kg of body weight per h). Another 10 pigs were also infused with endotoxin plus adenosine (150 microg/kg/min [i.v.]); this treatment was begun 30 min prior to the beginning of endotoxin treatment. Control groups (five animals per group) received either adenosine or physiological saline. Infusion of endotoxin caused severe neutropenia, shedding of L-selectin, upregulation of beta2-integrins, increased binding of C3-coated zymosan particles, and subsequent phagocytosis by PMNL. While phagocytosis-induced production of oxygen radicals appeared to decrease, extracellular release of superoxide anions was strongly enhanced. Infusion of adenosine during endotoxemia had no effect on neutropenia, expression of adhesion molecules, C3-induced adhesion, phagocytosis, or intracellular production of oxygen radicals, whereas extracellular release of O2- was strongly inhibited. Thus, i.v. infusion of adenosine during endotoxemia could be useful in protecting from O2(-)-mediated tissue injury without compromising the bactericidal mechanisms of PMNL.
Shiga Toxin 1 from<i>Escherichia coli</i>Blocks Activation and Proliferation of Bovine Lymphocyte Subpopulations In Vitro (1999)

Shiga toxin-producing Escherichia coli (STEC) is widespread in the cattle population, but the clinical significance of Shiga toxins (Stx's) for the bovine species remains obscure. Since Stx's exert immunomodulating effects in other species, we examined the effect of purified Stx1 on a bovine B lymphoma cell line (BL-3) and peripheral blood mononuclear cells (PBMC) isolated from adult bovine blood by viability assays and flow cytometry analysis. Stx1 markedly induced apoptosis in stimulated BL-3 cells. The susceptibility of this B-cell-derived cell line was induced only by either lipopolysaccharide (LPS) or pokeweed mitogen, while cultures stimulated with T-cell mitogens were unaffected by the toxin. In contrast, Stx1 did not induce cellular death-neither apoptosis nor necrosis-in primary cultures of PBMC but hindered the mitogen-induced increase in metabolic activity. The influence of Stx1 on single PBMC subpopulations varied with the type of mitogenic stimulus applied. Stimulation with phytohemagglutinin P particularly induced the proliferation of bovine CD8-expressing (BoCD8(+)) cells, and this proliferative response was blocked by Stx1. On the other hand, Stx1 reduced the portion of viable B cells in the presence of LPS. Modulation of activation marker expression (BoCD25 and BoCD71) by Stx1 indicated that the toxin hindered the proliferation of cells by blocking their activation. In conclusion, we assume that Stx1 contributes to the pathogenesis of STEC-associated diarrhea in calves by suppressing the mucosa-associated immune response. The usefulness of cattle as a model in which to study Stx-induced immunomodulation is discussed.
SQUARE ROOT TRANSFORM FOR THE ANALYSIS OF QUANTUM FLUCTUATIONS IN SPECTRUM DATA (1973)

Abstract Statistical fluctuations of pulse height distributions are analyzed from a view-point of noise elimination. The square root transform of the spectrum data that provides an additive characteristic to the relationship between the signal and the noise component is proposed for effective filtering of the data. Numerical simulations of this technique show that smoothing of the spectrum data is more effectively carried out by this transformation.
Tracking low elevation targets in the presence of multipath propagation (1994)

A tracking algorithm based on a measurement model of the multipath propagation effects on the elevation angle measurements is presented. This algorithm does not depend on the specific signal processing and the prevailing environmental conditions. The results of simulations based on several scenarios are presented. The signal processing model used to generate the elevation measurements of a low-flying target with multipath effects is also described. This mode incorporates a spherical Earth and finite target range in the geometry of reflection. The algorithm clearly indicates when the measurements are degraded, in which case it automatically increases the variance of the altitude estimate.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Pursuing Both Breadth and Depth in Qualitative Research: Illustrated by a Study of the Experience of Intimate Caring for a Loved One with Alzheimer's Disease (2005)

In this article, the authors explore the methodological and epistemological tensions between breadth and depth with reference to a study into the experience of caring for a loved one with Alzheimer's disease. They consider the benefits and limitations of each of two phases of the study: a generic qualitative study of narrative breadth and a descriptive phenomenological study of lifeworld depth into selected phenomena. The article concludes with a reflection on the kinds of distinctive knowledge generated by each of these two phases and the benefits of their complementary relationship with one another.

The main purpose of this study is that explains the aerodynamic drag reduction mechanism of a passenger car via an actively translating rear diffuser device at a high speed driving condition. The base pressure of the rear surface of passenger car is increased by install the rear diffuser device, because it prevents the low pressure air coming through the underbody from directly soaring up to the rear surface of the trunk. At the same time, it increases a diffusing effect to underbody flow which lowers the velocity and raises the pressure, bringing about an aerodynamic drag reduction.</div><div class="htmlview paragraph">Finally, the automobile aerodynamic drag is reduced about an average of more than 4% in 450 mm length with the base configuration.

At the end, the diffuser device was applied to the YF SONATA developed and produced by the Hyundai Motors Company. The drag reduction was achieved up to 5.2% in the speed range of 80 km/h ~ 120 km/h. In addition, owing to generation of negative lift by the diffuser device, it is expected the driving stability improved in high speed condition.</div></div>

Large impact of strontium substitution on photocatalytic water splitting activity of BaSnO3 (2007)

The effects of Sr substitution for Ba on photocatalytic water splitting activity of BaSnO3 were investigated experimentally and theoretically. The chemical incorporation of Sr into BaSnO3 induced a great enhancement for H2 production. Density function theory calculations of Ba1−xSrxSnO3 (x=0, 0.5, and 1.0) reveal that the bottom of the conduction band is gradually pushed up and the contribution of the Sr 5s orbitals to the bottom of the conduction band gradually becomes dominant with the increase of Sr concentration from x=0 to x=1.0. The participation of the normally inert Sr cation in the electronic structure of the SnO32− framework not only enhances the reduction ability of photoinduced electrons but also provides favorable opportunities for charge carrier transport, thus enhancing the photocatalytic activity of BaSnO3.
Experiment and theory for heterogeneous nucleation of protein crystals in a porous medium (2006)

The determination of high-resolution structures of proteins requires crystals of suitable quality. Because of the new impetus given to structural biology by structural genomics/proteomics, the problem of crystallizing proteins is becoming increasingly acute. There is therefore an urgent requirement for the development of new efficient methods to aid crystal growth. Nucleation is the crucial step that determines the entire crystallization process. Hence, the holy grail is to design a "universal nucleant," a substrate that induces the nucleation of crystals of any protein. We report a theory for nucleation on disordered porous media and its experimental testing and validation using a mesoporous bioactive gel-glass. This material induced the crystallization of the largest number of proteins ever crystallized using a single nucleant. The combination of the model and the experimental results opens up the scope for the rational design of nucleants, leading to alternative means of controlling crystallization.
