Comparative Corrosion Behavior of Two Palladium-Containing Titanium Alloys (2006)

The ASTM standard B 265 provides the requirements for the chemical composition of titanium (Ti) alloys. It is planned to use corrosion resistant and high strength titanium alloys to fabricate the drip shield at the proposed Yucca Mountain Repository. Titanium grade (Gr) 7 (R52400) and other Ti alloys are currently being characterized for this application. Ti Gr 7 contains 0.15% Palladium (Pd) to increase its corrosion performance. In this article we report results on the comparative short term corrosion behavior of Ti Gr 7 and a Ruthenium (Ru) containing alloy (Ti Gr 33). Ti Gr 33 also contains a small amount of Pd. Limited electrochemical testing such as polarization resistance and cyclic potentiodynamic curves showed that both alloys have a similar corrosion behavior in the tested environments.
Tissue culture infectivity of different strains of infectious bursal disease virus is determined by distinct amino acids in VP2 (1999)

Two types of strains of serotype I of infectious bursal disease virus (IBDV) have been described, on the basis of their ability (IBDV-TC) or inability (IBDV-BU) to infect chicken embryonic cells in culture. However, both types infect B lymphocytes in the bursa of Fabricius of young chickens. To determine the molecular basis for tissue culture infectivity, virus recombinants with chimeric segments A were constructed from IBDV-TC and IBDV-BU by reverse genetics. The region responsible for the different phenotypes was located in VP2. Site-directed mutagenesis identified single amino acids that are responsible for the restriction in infectivity. However, the appropriate amino acid exchanges are strain-specific.
Tunable Hot-Electron Transfer Within a Single Core-Shell Nanowire (2011)

We report the hot photoexcited electron transfer across the coaxial interface of a cylindrical core-shell nanowire. Modulation of the transfer rates, manifested as a large tunability of the voltage onset of negative differential resistance and of voltage-current phase, is achieved using three different modes. The coupling of electrostatic gating, incident photon energy, and the incident photon intensity to transfer rates is facilitated by the combined influences of geometric confinement and heterojunction shape on hot-electron transfer, and by electron-electron scattering rates that can be altered by varying the incident photon flux, with evidence of weak electron-phonon scattering. Dynamic manipulation of this transfer rate permits the introduction and control of a continuously adjustable phase delay of up to ∼130° within a single nanometer-scale device element.
Protection and mechanism of action of a novel human respiratory syncytial virus vaccine candidate based on the extracellular domain of small hydrophobic protein (2014)

Infections with human respiratory syncytial virus (HRSV) occur globally in all age groups and can have devastating consequences in young infants. We demonstrate that a vaccine based on the extracellular domain (SHe) of the small hydrophobic (SH) protein of HRSV, reduced viral replication in challenged laboratory mice and in cotton rats. We show that this suppression of viral replication can be transferred by serum and depends on a functional IgG receptor compartment with a major contribution of FcγRI and FcγRIII. Using a conditional cell depletion method, we provide evidence that alveolar macrophages are involved in the protection by SHe-specific antibodies. HRSV-infected cells abundantly express SH on the cell surface and are likely the prime target of the humoral immune response elicited by SHe-based vaccination. Finally, natural infection of humans and experimental infection of mice or cotton rats does not induce a strong immune response against HRSV SHe. Using SHe as a vaccine antigen induces immune protection against HRSV by a mechanism that differs from the natural immune response and from other HRSV vaccination strategies explored to date. Hence, HRSV vaccine candidates that aim at inducing protective neutralizing antibodies or T-cell responses could be complemented with a SHe-based antigen to further improve immune protection.
Broadband Terahertz Signal Processing and Multiplexing with Four-wire Waveguides (2022)

We demonstrate a new waveguide geometry, namely a four-wire waveguide, which acts as a terahertz polarization-division multiplexer and a novel platform to realize versatile signal-processing functionalities into independent channels over a broadband terahertz frequency range.
On-board Single-Phase Electric Vehicle Charger with Active Front End (2018)

Mass adoption of electric vehicles (EVs) is contingent on the availability of charging infrastructure. One solution to this issue is the introduction of on-board chargers, but such solutions typically require the installation of additional magnetic components that increase EV mass. An alternative approach is the dynamic re-deployment of drivetrain components for stationary charging. This work proposes an on-board single-phase charger that re-uses the traction inverter and motors. The system consists of a dual inverter drivetrain, which affords higher voltage charging compared to other systems. In addition, the system is able to operate bidirectionally and operate at any power factor for grid support services with real and reactive power without subjecting the motor to low frequency harmonic currents. The principle of operation and control of the proposed system is presented and demonstrated by simulation results.

Reduced Overhead Gate Level Logic Encryption (2016)

Untrusted third-parties are found throughout the integrated circuit (IC) design flow resulting in potential threats in IC reliability and security. Threats include IC counterfeiting, intellectual property (IP) theft, IC overproduction, and the insertion of hardware Trojans. Logic encryption has emerged as a method of enhancing security against such threats, however, current implementations of logic encryption, including the XOR or look-up table (LUT) techniques, have high per-gate overheads in area, performance, and power. A novel gate level logic encryption technique with reduced per-gate overheads is described in this paper. In addition, a technique to expand the search space of a key sequence is provided, increasing the difficulty for an adversary to extract the key value. A power reduction of 41.50%, an estimated area reduction of 43.58%, and a performance increase of 34.54% is achieved when using the proposed gate level logic encryption instead of the LUT based technique for an encrypted AND gate.
Motion vector coding by using representation of norm and angle components (2006)

Abstract Since many video coding methods use prediction between motion‐compensated frames, the motion vector must be transmitted. A large amount of code is generated for DCT coefficients for the motion vector. Therefore, prediction is performed from the motion vectors of neighboring blocks and variable‐length coding of the horizontal and vertical components of the prediction error vector is performed to reduce the amount of generated code. However, since this method handles the horizontal and vertical components as independent components, appropriate code assignment for coding the prediction error vector may not be possible. In this paper, the authors propose a method of coding by using norm and angle components to represent the prediction error vector and compare its coding efficiency with the conventional method to show its effectiveness. ©2006 Wiley Periodicals, Inc.

The <i>hedgehog</i> gene family in <i>Drosophila</i> and vertebrate development (1994)

The segment polarity gene hedgehog plays a central role in cell patterning during embryonic and post-embryonic development of the dipteran, Drosophila melanogaster. Recent studies have identified a family of hedgehog related genes in vertebrates; one of these, Sonic hedgehog is implicated in positional signalling processes that show interesting similarities with those controlled by its Drosophila homologue.
Selective anticancer activity of β-lactams derived from polyaromatic compound. (2013)

Currently available anticancer drugs are cytotoxic to normal as well as to neoplastic cells, therefore the synthesis of β-lactams as new and novel anticancer agents is extremely significant. We previously developed synthetic methods for the preparation of β-lactams and anticancer agents resulting from polyaromatic amines. There have also been reports on the synthesis and biological evaluation of novel racemic β-lactams as anticancer agents. In cell cycle analysis, these compounds demonstrated a G2 blockage against sensitive tumor cell lines. In the present study, useful and selective biological activities of chrysene β-lactams are described.
Frequency Band Selectable Microwave Photonic Multiband Bandpass Filter based on Lyot filter (2015)

Text Driven 3D Photo-Realistic Talking Head. (2011)

We propose a new 3D photo-realistic talking head with a personalized, photo realistic appearance. Different head motions and facial expressions can be freely controlled and rendered. It extends our prior, high-quality, 2D photo-realistic talking head to 3D. Around 20-minutes of audio-visual 2D video are first recorded with read prompted sentences spoken by a speaker. We use a 2D-to-3D reconstruction algorithm to automatically adapt a general 3D head mesh model to the individual. In training, super feature vectors consisting of 3D geometry, texture and speech are formed to train a statistical, multi-streamed, Hidden Markov Model (HMM). The HMM is then used to synthesize both the trajectories of geometry animation and dynamic texture. The 3D talking head animation can be controlled by the rendered geometric trajectory while the facial expressions and articulator movements are rendered with the dynamic 2D image sequences. Head motions and facial expression can also be separately controlled by manipulating corresponding parameters. The new 3D talking head has many useful applications such as voice-agent, tele-presence, gaming, social networking, etc.
Optical multilayer films based on an amorphous fluoropolymer (1996)

Multilayered coatings were made by physical vapor deposition (PVD) of a perfluorinated amorphous polymer, Teflon AF2400, and with other optical materials. A high reflector for 1064 nm light was made with ZnS and AF2400. An all-organic 1064 nm reflector was made from AF2400 and polyethylene. Oxide (HfO2 and SiO2) compatibility with AF2400 was also tested. The multilayer morphologies were influenced by coating stress and unintentional temperature rises from the PVD process. Analysis by liquid nuclear magnetic resonance of the thin films showed slight compositional variations between the coating and starting materials of perfluorinated amorphous polymers.

IDENTIFICATION OF A VACCINE CANDIDATE IN PROTEIN EXTRACTS FROM FRANCISELLA TULARENSIS (2003)

D e d i c a t i o n ii To my family: Joseph and Margaret Sikora, and my brother Gregory. Thanks for putting up with me and my antics. You have been a pleasant constant throughout my life. Thanks for supporting me when I decided to go where I wanted. I won&apos;t be finished for a while. To John Cherwonogrodzky (aka Jonny Fever). Your excitement in research has sparked an interest in bacteriology which I have brought to my medical studies and hope to continue throughout my life. Francisella tularensis is one of a small group of bacteria recognized for their virulence and potential for use as biological weapons. In this study we utilize a novel approach to identify an immunologically prominent component of F. tularensis that appears to be a promising vaccine candidate. Francisella is an intracellular pathogen that infects cells of the reticuloendothelial system. Other bacteria, such as Brucella spp. have this part of their life cycle in common. However, while mice injected with F. tularensis all die within three weeks
A Multiband Inductor-Reuse CMOS Low-Noise Amplifier (2008)

This paper presents the design and implementation of a new multiband, multistandard CMOS low-noise amplifier (LNA) that reuses inductors for different frequency bands to minimize chip area. The idea is to adaptively reconfigure a CMOS transistor in either common source or common gate configuration to achieve narrow-band (NB) or wide-band (WB) input matching, respectively, while conveniently reusing input and load inductors for both bands. This architecture is suitable for 802.11 a/b/g and Public Safety Broadband (PSB) applications, where the NB configuration covers wireless local area network (WLAN) 802.11 b/g, while the WB configuration accommodates the PSB at 4.9 GHz and WLAN 802.11 a. Two versions of the proposed idea, a tapped-capacitor and a tapped-inductor input-matched LNA, have each been designed and fabricated in 0.13-mum CMOS and measurement results are demonstrated.

Identification of Residues in CD6 Which Are Critical for Ligand Binding (1997)

CD6 is a member of the scavenger receptor cysteine rich protein superfamily (SRCRSF). This family includes many cell surface proteins whose three-dimensional structures and functions are presently not well understood. The extracellular region of CD6 includes 3 SRCR domains. The membrane proximal SRCR domain specifically binds the activated leukocyte cell adhesion molecule (ALCAM), a CD6 ligand belonging to the immunoglobulin superfamily. CD6-ALCAM interactions mediate immune cell adhesion and are implicated in T cell maturation and the regulation of T cell function. On the basis of SRCRSF sequence comparison, a mutagenesis analysis of the membrane proximal SRCR domain of CD6 (CD6D3) has been carried out. Fifteen mutants were characterized. Three CD6 residues were identified in a region of low sequence conservation which, when mutated, abolish ligand binding but not the binding to a panel of conformationally sensitive anti-CD6 mAbs. This study provides the first analysis of residues critical for ligand binding to a member of the SRCRSF.

Improved hot-carrier resistance with fluorinated gate oxides (1990)

Improved OFF-state hot-carrier resistance in n-channel MOSFETs observed for fluorinated gate oxides is discussed. One-micrometer fluorinated devices consistently showed approximately three times smaller transconductance reduction and threshold-voltage shift relative to the control (nonfluorinated) MOSFETs. The fluorine was incorporated into the gate oxide by low-energy ion implantation followed by a 920 degrees C diffusion. Subthreshold measurements taken before and after hot-electron stress explicitly show the reduction in interface state generation with fluorine incorporation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A MM-Wave SAR-Design for Helicopter Application (ROSAR) (1986)

First developments on Synthetic Aperture Radar (SAR) system based on use of Doppler information to obtain high resolution in azimuth direction were originated in 1951 by Carl Wiley. For short range battlefield reconnaissance applications mm wave imaging sensors find increasing interest. Preliminary studies show that high resolution SAR sensors in the usual sidelooking configuration may be developed at 35 GHz and 94 GHz in the near future. Imaging systems, based on Synthetic Aperture Radar concept for airborne and spaceborne applications are designed for a straight linear flight path. In this paper an unusual concept of a Synthetic Aperture Radar with rotating antennas for high resolution imaging is discussed, based on the rotational rather than the translational movement of the antenna phase center. The ROSAR concept has potential benefits for civil and military helicopter borne imaging applications, if the antennas are mounted at the tips of the rotor blades, for example. The concept has two main potential benefits, that are, the imaging field of view is 360° and there is no need for a forward velocitiy, because the rotor induced Doppler spectrum is used for imaging only. For the special helicopter requirements the mm wave frequencies (35 GHz/94 GHz) looks feasible. As opposed to SAR systems, based on linear antenna movement, high resolution ROSAR imaging is based on synthetic apertures of circular shape and the ROSAR processing differs considerably from the regular SAR processing schemes.
<i>In vitro</i> fermentability of human milk oligosaccharides by several strains of bifidobacteria (2007)

This study was conducted to investigate the catabolism and fermentation of human milk oligosaccharides (HMO) by individual strains of bifidobacteria. Oligosaccharides were isolated from a pooled sample of human milk using solid-phase extraction, and then added to a growth medium as the sole source of fermentable carbohydrate. Of five strains of bifidobacteria tested (Bifidobacterium longum biovar infantis, Bifidobacterium bifidum, Bifidobacterium longum biovar longum, Bifidobacterium breve, and Bifidobacterium adolescentis), B. longum bv. infantis grew better, achieving triple the cell density then the other strains. B. bifidum did not reach a high cell density, yet generated free sialic acid, fucose and N-acetylglucosamine in the media, suggesting some capacity for HMO degradation. Thin layer chromatography profiles of spent fermentation broth suggests substantial degradation of oligosaccharides by B. longum bv. infantis, moderate degradation by B. bifidum and little degradation by other strains. While all strains were able to individually ferment two monosaccharide constituents of HMO, glucose and galactose, only B. longum bv. infantis and B. breve were able to ferment glucosamine, fucose and sialic acid. These results suggest that as a potential prebiotic, HMO may selectively promote the growth of certain bifidobacteria strains, and their catabolism may result in free monosaccharides in the colonic lumen.
A Game Platform for Treatment of Amblyopia (2011)

We have developed a prototype device for take-home use that can be used in the treatment of amblyopia. The therapeutic scenario we envision involves patients first visiting a clinic, where their vision parameters are assessed and suitable parameters are determined for therapy. Patients then proceed with the actual therapeutic treatment on their own, using our device, which consists of an Apple iPod Touch running a specially modified game application. Our rationale for choosing to develop the prototype around a game stems from multiple requirements that such an application satisfies. First, system operation must be sufficiently straightforward that ease-of-use is not an obstacle. Second, the application itself should be compelling and motivate use more so than a traditional therapeutic task if it is to be used regularly outside of the clinic. This is particularly relevant for children, as compliance is a major issue for current treatments of childhood amblyopia. However, despite the traditional opinion that treatment of amblyopia is only effective in children, our initial results add to the growing body of evidence that improvements in visual function can be achieved in adults with amblyopia.
A New Variable Step-Size NLMS Algorithm and Its Performance Analysis (2011)

Numerous variable step-size normalized least mean-square (VSS-NLMS) algorithms have been derived to solve the dilemma of fast convergence rate or low excess mean-square error in the past two decades. This paper proposes a new, easy to implement, nonparametric VSS-NLMS algorithm that employs the mean-square error and the estimated system noise power to control the step-size update. Theoretical analysis of its steady-state behavior shows that, when the input is zero-mean Gaussian distributed, the misadjustment depends only on a parameter β controlling the update of step size. Simulation experiments show that the proposed algorithm performs very well. Furthermore, the theoretical steady-state behavior is in very good agreement with the experimental results.
