Design of common gate UWB LNA in CMOS (2009)

A single-ended and a differential LNA with common-gate input stage are designed and measured. Measurements show that both LNA achieve good sufficient gain (S21) and well input matching (S11) over a wide range of frequency under low power consumption. The differential LNA uses capacitor-cross coupling (CCC) and current-reuse techniques to achieve better performances than the single-ended LNA.
Using seismic crosswell surveys to determine the aperture of partially water-saturated fractures (1999)

Abstract An air injection experiment in a shallow fractured limestone at Conoco's borehole test facility near Newkirk, Oklahoma, has shown large effects on the amplitude but small effects on the traveltime of the transmitted seismic waves. We have analyzed data from a seismic monitor survey in the kilohertz range performed during the experiment and have modeled the fracture zone as a single fracture. The large amplitude decrease during the experiment is mainly attributable to the impedance contrast between the small velocities of gas-water mixtures inside the fracture and the formation. The intrinsic attenuation of the fracture fluid seems to be a second-order effect for small apertures. During the experiment the seismic wavelengths inside the fracture become comparable to the aperture dimension, which allows an estimation of fracture apertures. We also have analyzed a crosswell survey acquired shortly after the experiment and computed aperture and gas concentration profiles. Our aperture estimates range from &lt;1 mm to a few millimeters, which is comparable to previous tracer tests. The results of this study are generally consistent with prior hydrologic work and single-well surveys. This study demonstrates that crosswell surveys could be an effective tool for obtaining in situ estimates of fracture aperture and gas concentration.
Robust Speech Recognition by Integrating Speech Separation and Hypothesis Testing (2006)

Missing data methods attempt to improve robust speech recognition by distinguishing between reliable and unreliable data in the time-frequency domain. Such methods require a binary mask which labels time-frequency regions of a noisy speech signal as reliable if they contain more speech energy than noise energy and unreliable otherwise. Current methods for estimating the mask are based mainly on bottom-up speech separation cues such as harmonicity and produce labeling errors that cause a degradation in recognition performance. We propose a two stage recognition system in order to improve mask estimation and produce better recognition results. First, an n-best lattice consistent with the speech separation mask is generated. The lattice is then re-scored by expanding the mask using a model-based hypothesis test to determine the reliability of individual time-frequency regions. Systematic evaluations show significant improvement in recognition performance compared to that using speech separation.
Sugar-Mediated Uptake of Glycosylated Polylysines and Gene Transfer into Normal and Cystic Fibrosis Airway Epithelial Cells (1999)

We have examined the membrane lectin expressed by immortalized normal and cystic fibrosis (CF) airway epithelial cells, using fluorescein-labeled neoglycoproteins; the uptake of plasmid DNA using fluoresceinylated glycoplexes (plasmid/glycosylated polylysine complexes); and the efficiency of gene transfer when glycosylated polylysines and glycosylated, partially gluconoylated polylysines were used as vectors. The most efficient uptake of neoglycoproteins by normal and CF cells was obtained with mannosylated BSA (bovine serum albumin). Similarly, the most efficient uptake of plasmid DNA was obtained with glycoplexes bearing alpha-D-Man residues. Surprisingly, glycoplexes bearing alpha-D-Man residues were poorly efficient for gene transfer into normal and CF cells. The highest luciferase activity was achieved with lactosylated polylysine- and beta-D-GlcNAc-substituted gluconoylated polylysine as vectors. Gene transfer efficiency obtained with gluconoylated polylysine bearing beta-D-GlcNAc residues was similar to that observed with polyethylenimine (PEI; 25 and 800 kDa) and 10-fold higher than that observed with lipofectin and LipofectAMINE. These results suggest that the transfection efficiency with glycoplexes is not determined only by the specificity of the lectin expressed at the cell surface membrane but also by intracellular trafficking of the glycoplexes, which could be mediated by lectins present inside the cells.
A novel fabrication route for auxetic polyethylene, part 2: Mechanical properties (2008)

Abstract Auxetic ultra high molecular weight polyethylene (UHMWPE) has been fabricated by omitting the extrusion stage usually required to form the characteristic nodule‐fibril microstructure of this material. This new route consists of compaction followed by multiple sintering treatments, with the best results using two successive sintering treatments. This article examines the mechanical properties of cylindrical compacts subjected to between one and four successive sintering treatments. The indentation resistance of the double‐sintered material was found to be 2.5 times that of conventionally processed UHMWPE and similar to that found in the extruded form of auxetic polyethylene. The flexural strength and strain to failure increase dramatically with the first sintering treatment and then remain almost constant. This processing route has potential for the production of more complex, useful shapes than can currently be produced since it removes the limitations imposed by the geometry of the barrel required for the extrusion stage.

Biological and chemical characterization of lipopolysaccharide from Selenomonas spp. in human periodontal pockets (1986)

Pure lipopolysaccharide extracted from Selenomonas spp. isolated from human periodontal pockets was composed of 23.7% carbohydrate, 16.5% hexosamine, 1.2% 2-keto-3-deoxyoctonate, 0.7% heptose, 26.0% lipid, 1.8% protein, and 1.3% phosphorus. It was shown to be quite lethal, to have very active pyrogenicity, to give a typical biphasic-fever response, and to produce a positive local Shwartzman reaction.
Well Passivated a-Si:H Back Contacts for Double-Heterojunction Silicon Solar Cells (2006)

We have developed hydrogenated amorphous silicon (a-Si:H) back contacts to both p-and n-type silicon wafers, and employed them in double-heterojunction solar cells. These contacts are deposited entirely at low temperature (<250degC) and replace the standard diffused or alloyed back-surface-field contacts used in single-heterojunction (front-emitter only) cells. High-quality back contacts require excellent surface passivation, indicated by a low surface recombination velocity of minority-carriers (S) or a high open-circuit voltage (V <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">oc</sub> ). The back contact must also provide good conduction for majority carriers to the external circuit, as indicated by a high light I-V fill factor. We use hot-wire chemical vapor deposition (HWCVD) to grow a-Si:H layers for both the front emitters and back contacts. Our improved a-Si:H back contacts contribute to our recent achievement of a confirmed 18.2% efficiency in double-heterojunction silicon solar cells on p-type textured silicon wafers [1]
Semi-empirical PM3 calculation reveals the relationship between the fluorescence characteristics of 4,7-disubstituted benzofurazan compounds, the LUMO energy and the dipole moment directed from the 4- to the 7-position (1999)

This article elucidates the relationships between the chemical structure and the fluorescence characteristics (fluorescence intensity, maximum excitation wavelength and maximum emission wavelength) of 4,7-disubstituted benzofurazan compounds with computer calculation. Our previous study using Hammett substituent constants of the substituent groups at the 4- and the 7-positions suggested that the total of electron densities on the benzofurazan skeleton and the dipole moment directed from the 4- to the 7-position might affect the fluorescence characteristics of these compounds. The sum of atomic charges on the benzofurazan skeleton, the HOMO energy and the LUMO energy were selected as parameters to reflect the total of electron densities on the benzofurazan skeleton and were obtained with the AM1 and PM3 calculations. The dipole moment directed from the 4- to the 7-position was also calculated with two hamiltonians. The LUMO energy and the dipole moment from the 4- to the 7-position obtained with the PM3 calculation is most closely related with the fluorescence characteristics. Using these parameters, the fluorescent 4,7-disubstituted benzofurazan compounds were classified into two groups, and the maximum excitation and emission wavelengths were different between these two groups. These relationships indicated that the fluorescence characteristics of 4,7-disubstituted benzofurazan compounds were determined by the total of electron densities on the benzofurazan skeleton and the dipole moment directed from the 4- to the 7-position. Furthermore, we predicted the fluorescence characteristics of four 4,7-disubstituted benzofurazan compounds based on the relationships obtained, and confirmed that the prediction agreed with the measured data.

Optimal software pipelining of nested loops (2002)

The article presents an approach to software pipelining of nested loops. While several articles have addressed software pipelining of single (non-nested) loops, little work has been done in the area of applying it to nested loops. The article solves the problem of finding the minimum iteration initiation interval (in the absence of resource constraints) for each level of a nested loop. The problem is formulated as one of finding a rational quasi-affine schedule for each statement in the body of a perfectly nested loop which is then solved using linear programming. This allows us to treat iteration-dependent statement reordering and multidimensional loop unrolling in the same framework. Unlike most work in scheduling nested loops, we treat each statement in the body as a unit of scheduling. Thus, the schedules derived allow for instances of statements from different iterations to be scheduled at the same time. Optimal schedules derived here subsume extant work on software pipelining of non-nested loops, in the absence of resource constraints.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Equivalent Circuits for the Analysis and Synthesis of Switched Capacitor Networks (1979)

An extensive library of z-domain building block equivalent circuits is derived to facilitate the analysis and synthesis of switched capacitor (sc) networks. These sc building blocks, typically comprised of a single capacitor and from one to four switches, serve as basic circuit elements for sc networks in much the same spirit that resistors and capacitors serve analog networks. This building block library facilitates the derivation of canonic z-domain equivalent circuits for complex sc networks and the application of well-established mathematical network analysis and synthesis toots. What has been sought are easily applied techniques for achieving the same insights for sc networks that we have long enjoyed with analog networks.
Role of the SCFSkp2 Ubiquitin Ligase in the Degradation of p21Cip1 in S Phase (2003)

The cyclin-dependent kinase inhibitor p21Cip1 has important roles in the control of cell proliferation, differentiation, senescence, and apoptosis. It has been observed that p21 is a highly unstable protein, but the mechanisms of its degradation remained unknown. We show here that p21 is a good substrate for an SCF (Skp1-Cullin1-F-box protein) ubiquitin ligase complex, which contains the F-box protein Skp2 (S phase kinase-associated protein 2) and the accessory protein Cks1 (cyclin kinase subunit 1). A similar ubiquitin ligase complex has been previously shown to be involved in the degradation of a related cyclin-dependent kinase inhibitor, p27Kip1. The levels of Skp2 oscillate in the cell cycle, reaching a maximum in S phase. The ubiquitylation of p21 in vitro required the supplementation of all components of the SCF complex as well as of Cks1 and Cdk2-cyclin E. The protein kinase Cdk2-cyclin E acts both by the phosphorylation of p21 on Ser-130 and by the formation of a complex with p21, which is required for its presentation to the ubiquitin ligase. As opposed to the case of p27, the phosphorylation of p21 stimulates its ubiquitylation but is not absolutely required for this process. Levels of p21 are higher in Skp2-/- mouse embryo fibroblasts than in wild-type fibroblasts in the S phase, and the rates of the degradation of p21 are slower in cells that lack Skp2. It is suggested that SCFSkp2 participates in the degradation of p21 in the S phase.

A simple apparatus for investigating electron paramagnetic resonance (EPR) in a magnetic field of 100 gauss is described. A one-tube oscillating detector with a shorted, quarter-wave coaxial line resonant circuit, operating at 315 Mc, is used. The 100-gauss field is obtained from small Helmholtz coils. The auxiliary electronic equipment required to operate this apparatus is conventional.
Caspase‐dependent cleavage of the mono‐<scp>ADP</scp>‐ribosyltransferase <scp>ARTD</scp>10 interferes with its pro‐apoptotic function (2013)

ADP-ribosylation is a post-translational modification that regulates various physiological processes, including DNA damage repair, gene transcription and signal transduction. Intracellular ADP-ribosyltransferases (ARTDs or PARPs) modify their substrates either by poly- or mono-ADP-ribosylation. Previously we identified ARTD10 (formerly PARP10) as a mono-ADP-ribosyltransferase, and observed that exogenous ARTD10 but not ARTD10-G888W, a catalytically inactive mutant, interferes with cell proliferation. To expand on this observation, we established cell lines with inducible ARTD10 or ARTD10-G888W. Consistent with our previous findings, induction of the wild-type protein but not the mutant inhibited cell proliferation, primarily by inducing apoptosis. During apoptosis, ARTD10 itself was targeted by caspases. We mapped the major cleavage site at EIAMD406↓S, a sequence that was preferentially recognized by caspase-6. Caspase-dependent cleavage inhibited the pro-apoptotic activity of ARTD10, as ARTD10(1-406) and ARTD10(407-1025), either alone or together, were unable to induce apoptosis, despite catalytic activity of the latter. Deletion of the N-terminal RNA recognition motif in ARTD10(257-1025) also resulted in loss of pro-apoptotic activity. Thus our findings indicate that the RNA recognition motif contributes to the pro-apoptotic effect, together with the catalytic domain. We suggest that these two domains must be physically linked to stimulate apoptosis, possibly targeting ARTD10 through the RNA recognition motif to specific substrates that control cell death. Moreover, we established that knockdown of ARTD10 reduced apoptosis in response to DNA-damaging agents. Together, these findings indicate that ARTD10 is involved in the regulation of apoptosis, and that, once apoptosis is activated, ARTD10 is cleaved as part of negative feedback regulation.
Uridine-Based Inhibitors as New Leads for Antibiotics Targeting <i>Escherichia coli</i> LpxC (2009)

The UDP-3-O-(R-3-hydroxyacyl)-N-acetylglucosamine deacetylase LpxC catalyzes the committed reaction of lipid A (endotoxin) biosynthesis in Gram-negative bacteria and is a validated antibiotic target. Although several previously described compounds bind to the unique acyl chain binding passage of LpxC with high affinity, strategies to target the enzyme's UDP-binding site have not been reported. Here the identification of a series of uridine-based LpxC inhibitors is presented. The most potent examined, 1-68A, is a pH-dependent, two-step, covalent inhibitor of Escherichia coli LpxC that competes with UDP to bind the enzyme in the first step of inhibition. Compound 1-68A exhibits a K(I) of 54 muM and a maximal rate of inactivation (k(inact)) of 1.7 min(-1) at pH 7.4. Dithiothreitol, glutathione and the C207A mutant of E. coli LpxC prevent the formation of a covalent complex by 1-68A, suggesting a role for Cys-207 in inhibition. The inhibitory activity of 1-68A and a panel of synthetic analogues identified moieties necessary for inhibition. 1-68A and a 2-dehydroxy analogue, 1-68Aa, inhibit several purified LpxC orthologues. These compounds may provide new scaffolds for extension of existing LpxC-inhibiting antibiotics to target the UDP binding pocket.
Basic three-dimensional objects constructed with simplex meshes (2005)

In this paper we proposed several aIgorithms to construct the surface of three basic three-dimensional objects using 2-simplex meshes: sphere, cylinder, and torus. The algorithm for each basic model consists of three steps: creating vertices, edges and faces. Simplex mesh is a discrete model representation with a constant vertex connectivity. Each vertex of a 2-simplex mesh is connected to three, and only three, neighbors, These basic objects can be used as initial models to perform a deformation of its surface. The deformation fits these initial models to another target model.
Gastric Emptying Delay and Gastric Electrical Derangement in IDDM (1998)

Delay of gastric emptying time and gastric electrical abnormalities are found in a high proportion of children with diabetes and can contribute to poor glycemic control, most likely by causing a mismatch between the onset of insulin action and the delivery of nutrients into the small intestine. Diabetic children with unexplained poor glycemic control should be investigated for abnormalities in gastric motility.

How to Prove Yourself to Multiple Parties: Energy-Efficient Multi-group Authentication (2013)

Zero-knowledge identification (ZKI) schemes have been studied extensively in the cryptology literature and are currently being used commercially for radio frequency identification (RFID) authentication. Much like the public key cryptosystems that may be used to ensure message confidentiality, ZKI schemes rely on the hardness of certain problems -- e.g., factoring the product of large primes -- to provide secure authentication. In this paper, we extend existing ZKI schemes based on error-correcting codes to support multi-group authentication. In particular, we propose two schemes that enable a prover to simultaneously authenticate its membership in M ≥ 1 groups. The proposed multi-group authentication protocols are of particular relevance to military ad hoc networks, where group communications is the norm and energy efficiency is a critical performance metric.
Variability in Toxicity of the Dinoflagellate Alexandrium Tamarense Isolated from Hiroshima Bay, Western Japan, as a Reflection of Changing Environmental Conditions (2001)

The variability of cellular toxin content in the dinoflagellate Alexandrium tamarense isolated from Hiroshima Bay was analyzed under a variety of culture conditions. Growth and toxicity were represented as a function of light (80, 90, 110, 160 and 350 μmol m–2 s –1), temperature (12, 17 and 22°C), salinity (13, 16.5, 19.5, 25, 29, 33, 36.5 and 38 PSU) and ammonium concentration (0.11, 0.22 and 0.44 mM). Toxicity was measured by the tissue culture bioassay using mouse neuroblastoma cells, and expressed as saxitoxin concentration equivalents. Cellular toxicity increased with decreasing salinity. At temperatures of 17 and 22°C, maximum toxin content was observed at the lowest light intensity and growth rate. At the lowest temperature of 12°C, maximum toxin content was observed at intermediate light intensities and growth rates. A drastic increase in toxin content with an increase in ammonium concentration from 0.11 to 0.22 mM supported the idea that ammonium utilization for toxin production directly brings about a high toxin content inA. tamarense. Our results ecologically imply that the cells become highly toxic in environments with low salinity and high ammonium concentration, and successive cloudy days. Such environmental conditions may lead to increasing risk of shellfish toxification.
Breeding for Salinity Tolerance in Plants (1994)

Abstract Accumulation of high levels of salts in the soil is characteristic of arid and semi-arid regions. Although different curative and management measures are being used to render salt-affected soils fit for agriculture, they are extremely expensive and do not provide permanent solutions to overcome the salinity problem. In contrast, a biotic approach for overcoming salinity stress has gained considerable recognition within the past few decades in view of the vast experimental evidence from what has happened in nature concerning the evolution of highly salt-tolerant ecotypes of different plant species, and also from the remarkable achievements that have been made in improveing different agronomic traits through artificial selection. Considerable improvements in salt tolerance of important crop species have been achieved in the past 2 decades using barley, rice, pearl millet, maize, sorghum, alfalfa, and many grass species. Such achievements relied solely on assessment of the phenotypic expression of the features involved. Knowledge of the underlying physiological mechanisms producing those salt-tolerant individuals was not clearly known. The present review highlights the relationships between different physiological/biochemical variables being recommended as selection criteria, and salt tolerance of different plant species. This paper also lists different sources of genetic variation for salt tolerance since it is evident that for successful improvement in a character there must be a great amount of genetic variation present in the gene pool of a species.
