Capacitance Transient Spectroscopy of Trace Contamination in Silicon (1982)

Capacitance transient spectroscopy is applied to the study of trace contamination in semiconductor devices. The introduction of electrically active, process‐related defects in concentrations ≥1010 cm−3 is examined. Impurities are identified by correlation of the generated spectra with reference tables. The technique is effective in examining finished devices as well as in analyzing individual manufacturing steps.
Considerations for a tsat quality of service architecture (2005)

Transformation communications SATCOM (TSAT) is planned to be the satellite networking system for tactical and strategic warfighters of the future. TSAT is an integral part of the global information grid (GIG) architecture. The TSAT component of the architecture is used primarily in situations where user mobility, horizon limitations/obstructions or "last mile'' economic considerations favor SATCOM use over the other media. TSAT is being designed as both an IP and circuit based core network that can support a multitude of applications, those in use presently as well as futuristic ones envisaged by the DoD. These applications or application categories have different QoS requirements as they relate to parameters such as throughput, delay jitter and packet error rates. A critical objective of the TSAT program is to provide such differentiated and guaranteed QoS based services. Designing an optimal TSAT QoS architecture is a challenging proposition for a number of reasons. These include constraints associated with the onboard IP router, the bandwidth on demand based radio channels, long propagation delays, delay jitter due to TDMA, the large number of terminal types (fixed and mobile), separation between red/black networks, and DoD specific preemption and priority requirements (MLPP). This paper describes approaches being evaluated to solving different facets of the TSAT QoS problem. These include techniques for service differentiation, dynamic QoS signaling, management of flows and call admission control.
Conjugated Polymers of Intrinsic Microporosity (C‐PIMs) (2014)

Conjugated microporous polymers (CMPs) have shown great potential for energy and environmental issues, however, poor solubility and processability of most of these materials limit their applications. Herein, a range of linear conjugated polymers of intrinsic microporosity (C‐PIMs) is reported, combining for the first time the properties of conjugated microporous polymers, such as tunable electronic properties and compositional variation, with those of linear polymers of intrinsic microporosity (PIMs) allowing for solution processability and film formation. These soluble materials have a number of potential applications, for example as components in devices where large, porous interfaces are combined with extended electronic conjugation.
Anchored paired comparisons (2007)

The method of paired comparisons is often used in image quality evaluations. Psychometric scale values for quality judgments are modeled using Thurstone's Law of Comparative Judgment in which distance in a psychometric scale space is a function of the probability of preference. The transformation from psychometric space to probability is a cumulative probability distribution. The major drawback of a complete paired comparison experiment is that every treatment is compared to every other, thus the number of comparisons grows quadratically. We ameliorate this difficulty by performing paired comparisons in two stages, by precisely estimating anchors in the psychometric scale space which are spaced apart to cover the range of scale values and comparing treatments against those anchors. In this model, we employ a generalized linear model where the regression equation has a constant offset vector determined by the anchors. The result of this formulation is a straightforward statistical model easily analyzed using any modern statistics package. This enables model fitting and diagnostics. This method was applied to overall preference evaluations of color pictorial hardcopy images. The results were found to be compatible with complete paired comparison experiments, but with significantly less effort.
Molecular typing of Shigella strains (2017)

Shigelloses still provide one of the toughest health challenges in many countries, especially in developing ones. Current molecular-genetic techniques are increasingly replacing conventional phenotypic approaches to investigating Shigella-associated infections. The review describes available methods of typing Shigella bacteria, their potential applications and selection criteria depending on the research task. It also deals with their advantages and disadvantages. Such methods as PFGE (pulsed field gel electrophoresis), the "gold standard" in typing various pathogens, and MLVA (multi-locus variable number of tandem repeat analysis) are the most widely used Shigella typing procedures. These methods are often combined or used along with some other genotyping tools. In the nearest future, with the advent of web platforms allowing express processing data, whole genome sequence will possibly become more widely used in lab diagnostics to evaluate outbreaks and to perform epidemiological monitoring.
Structure of Hand/Mouse Movements (2015)

This study investigated the distribution of movement time (MT) and submovement time as a function of Fitts' index of difficulty (ID) to help understand the underlying mechanisms of Fitts' law. Many previous studies have shown that movements in such a task can be broken into a series of submovements, but have not been able to account for the variation of MT with ID under different conditions and for different tasks. The trajectory of computer mouse movements was recorded and analyzed to identify the distribution of submovements and MTs. The movement trajectory consists of a series of submovements with predictable probabilities. The first submovement is ballistic in nature and has an initiation time proportional to the movement amplitude. The verification time is dependent on target size. The probabilities of occurrence of each submovement can account for the variations in MT. The developed method has application to the evaluation of computer input devices, as the structure of the movement shows the ability of a person to control a device to minimize the time for movement.

Audiological and Surgical Correlates of Myringoplasty Associated with Ethnography in the Bay of Plenty, New Zealand (2022)

New Zealand Māori and pediatric populations required greater access to myringoplasty, achieving good surgical and audiological outcomes. Myringoplasty is highly effective and significantly improves hearing, particularly for New Zealand Māori. Pediatric success rates were equivalent to adults, supporting timely myringoplasty to minimize morbidity from untreated perforations.
Class-X—Harmonically Tuned Power Amplifiers With Maximally Flat Waveforms Suitable for Over One-Octave Bandwidth Designs (2018)

This paper proposes a new theory for harmonically tuned power amplifiers (PAs) with maximally flat waveforms, Class-X PAs. This class has been developed to achieve maximally flat waveforms. In this class, the relationship between the fundamental load impedance and the independently set second- and third-harmonic load impedances is established to maintain constant output power with constant efficiency. This relationship sets an optimum fundamental load design space when the second- and third-harmonic impedances are varied simultaneously and independently of each other. By varying the second- and third-harmonic impedances independently, higher flexibility in the design of broadband PAs is obtained. The theory of Class-X PA and its broadband characteristics were validated with an experimental design example using a Cree's 10-W Gallium Nitride (GaN) device. This design showed a measured drain efficiency higher than 70% and output power within 3-dB variation over more than one-octave bandwidth.need
Early photon tomography allows fluorescence detection of lung carcinomas and disease progression in mice in vivo (2008)

Imaging of targeted fluorescent probes offers significant advantages for investigating disease and tissue function in animal models in vivo. Conversely, macroscopic tomographic imaging is challenging because of the high scatter of light in biological tissue and the ill-posed nature of the reconstruction mathematics. In this work, we use the earliest-transmitted photons through Lewis Lung Carcinoma bearing mice, thereby dramatically reducing the effect of tissue scattering. By using a fluorescent probe sensitive to cysteine proteases, the method yielded outstanding imaging performance compared with conventional approaches. Accurate visualization of biochemical abnormalities was achieved, not only in the primary tumor, but also in the surrounding tissue related to cancer progression and inflammatory response at the organ level. These findings were confirmed histologically and with ex vivo fluorescence microscopy. The imaging fidelity demonstrated underscores a method that can use a wide range of fluorescent probes to accurately visualize cellular- and molecular-level events in whole animals in vivo.
Improving Quality of Life and Depression After Stroke Through Telerehabilitation (2015)

A robot-assisted intervention coupled with a home exercise program and a home exercise program alone administered using a telerehabilitation model may be valuable approaches to improving quality of life and depression in people after stroke.
Genetic Analysis of the Requirement for flp-2 , tadV , and rcpB in Actinobacillus actinomycetemcomitans Biofilm Formation (2006)

The tad locus of Actinobacillus actinomycetemcomitans encodes a molecular transport system required for tenacious, nonspecific adherence to surfaces and formation of extremely strong biofilms. This locus is dedicated to the biogenesis of Flp pili, which are required for colonization and virulence. We have previously shown that 11 of the 14 tad locus genes are required for adherence and Flp pilus production. Here, we present genetic and phylogenetic analyses of flp-2, tadV, and rcpB genes in biofilm formation. We show that tadV, predicted to encode prepilin peptidase, is required for adherence. In contrast, targeted insertional inactivation of flp-2, a gene closely related to the prepillin gene flp-1, did not abrogate biofilm formation. Expression studies did not detect Flp2-T7 protein under standard laboratory conditions. We present phylogenetic data showing that there is no significant evidence for natural selection in the available flp-2 sequences from A. actinomycetemcomitans, suggesting that flp-2 does not play a significant role in the biology of this organism. Mutants with insertions at the 3' end of rcpB formed biofilms equivalent to wild-type A. actinomycetemcomitans. Surprisingly, 5' end chromosomal insertion mutants in rcpB were obtained only when a wild-type copy of the rcpB gene was provided in trans or when the Tad secretion system was inactivated. Together, our results strongly suggest that A. actinomycetemcomitans rcpB is essential in the context of a functional tad locus. These data show three different phenotypes for the three genes.
ChemInform Abstract: SYNTHESIS AND SOME REACTIONS OF BENZO(F)QUINOLINE 5,6‐OXIDE (1978)

Energy-efficient packet transmission over a multiaccess channel (2003)

We investigate the minimum-energy packet scheduling problem for the multiaccess channel with K transmitters and a single receiver, assuming that packets arrive at each transmitter's buffer at arbitrary times and must be transmitted within a finite time window. The offline scheduling problem is formulated and found to be a convex optimization problem with linear constraints. An efficient algorithm for finding the optimal offline schedule is presented. An online schedule based on a lookahead buffer is described and shown to perform very closely in terms of average energy per packet to the offline optimal, at the expense of a nearly constant delay.
Invariant resolution dynamic focus OCM based on liquid crystal lens (2007)

A primary limitation of optical coherence microscopy is the lack of sufficient lateral resolution over a usable imaging volume for diagnostic applications, even with high-numerical aperture imaging optics. In this paper, we first motivate the benefit of refocusing at multiple depths in a highly scattering biological sample using optical coherence microscopy, which experimentally shows invariant 2.5 mum axial and 6.5 mum lateral resolution throughout the sample. We then present the optical system design of a hand-held probe with the advanced capability to dynamically focus with no moving parts to a depth of 2 mm in skin-equivalent tissue at 3 mum resolution throughout an 8 cubic millimeter imaging volume. The built-in dynamic focusing ability is investigated with an addressable liquid crystal lens embedded in a custom-designed optics optimized for a Ti:Sa pulsed broadband laser source of bandwidth 100nm centered at 800nm. The design was developed not only to account for refocusing into the tissue but also to minimize and compensate for the varying on-axis and off-axis optical aberrations that would be introduced throughout a 2 mm thick and 2 mm wide skin imaging volume. The MTF contrast functions and distortion plots at three different skin depths are presented.
Digital particle image velocimetry (DPIV) measurements of the velocity profiles through bileaflet mechanical valves: in vitro steady. (1996)

Although velocity profiles downstream of mechanical valves have been measured in-vitro using Laser Doppler Anemometry (LDA), these studies have not measured velocities in the immediate proximity of the leaflets since the LDA technique prevents velocities from being measured in the immediate vicinity of any structure. Laser based Digital Particle Image Velocimetry (DPIV) is a new technique that allows for accurate measurement of an entire two-dimensional velocity field with no beam angulation. DPIV was used to measure two-component velocity vectors immediately proximal and distal to a 25 mm bileaflet mechanical valve (St. Jude) mounted in a transparent steady flow in-vitro model. Measurements of flow similar in Reynolds number (Re) to mitral inflow (Re = 2000-4000) showed clear hemi-elliptical isovelocity convergence zones proximal to each of the three orifices. DPIV measurements of flow distal to the orifice revealed clear vortex rollups generated from the internal ring of the valve with separate velocity profiles immediately distal to the leaflets. These studies prove the feasibility of the DPIV technique to provide accurate velocity measurements of flow profiles through mechanical valves.
Stabilization of Colloidal Crystals Engineered with DNA (2018)

A postsynthetic method for stabilizing colloidal crystals programmed from DNA is developed. The method relies on Ag<sup>+</sup> ions to stabilize the particle-connecting DNA duplexes within the crystal lattice, essentially transforming them from loosely bound structures to ones with very strong interparticle links. Such crystals do not dissociate as a function of temperature like normal DNA or DNA-interconnected superlattices, and they can be moved from water to organic media or the solid state, and stay intact. The Ag<sup>+</sup> -stabilization of the DNA bonds is accompanied by a nondestructive ≈25% contraction of the lattice, and both the stabilization and contraction are reversible with the chemical extraction of the Ag<sup>+</sup> ions, by AgCl precipitation with NaCl. This synthetic tool is important, since it allows scientists and engineers to study such crystals in environments that are incompatible with structures made by conventional DNA programmable methods and without the influence of a matrix such as silica.
System-level study of OFDM and CDMA with adaptive modulation/coding for a 5 MHz channel (2004)

In this paper, the downlink performance of OFDM and CDMA cellular systems is investigated for deployment scenarios similar to those envisioned by the 3GPP. In particular, the system-level performance characteristics are studied for packet data oriented systems with adaptive modulation and coding (AMC), operating on a 5 MHz channel with one-cell frequency reuse. For the CDMA case, both Rake and MMSE receivers are considered. Three link adaptation scenarios are considered: ideal (fast) time-only adaptation, slow link adaptation (based on average C/(I+N)), and ideal time-frequency adaptation (only for OFDM). Performance is evaluated using indicators such as total throughput and data rate profile, for five propagation environments (pedestrian A and B, Vehicular A and B, and GSM typical urban) and for single antenna systems as well as space-time transmit diversity (STTD) systems. Results show a significant performance benefit for fast link adaptation in all systems, and also indicate that OFDM provides a performance benefit that depends on the channel delay spread.
Novel polyisobutylene / polydimethylsiloxane bicomponent networks: III. Tissue compatibility (1999)

The tissue biocompatibility of a series of novel rubbery polyisobutylene (PIB)/polydimethylsiloxane (PDMS) bicomponent networks was investigated by in vivo implantation into rats. Bicomponent networks of varying composition (PIB wt%/PDMS wt% = 70/30, 50/50, 35/65) as well as a standard polyethylene control were implanted intraperitoneally. After eight weeks the implants and surrounding tissue were removed for histological evaluation. In all scoring categories (i.e. collagen thickness, fibrous tissue orientation, collagen deposition in muscle tissue, lymphocyte infiltration, angiogenesis) the PIB/PDMS bicomponent network implants elicited either less or similar tissue and cellular response than polyethylene. To determine which implant elicited the least tissue and cellular response overall, a weighted score including collagen thickness, lymphocyte infiltration, and angiogenesis was calculated for each implant. According to these preliminary investigations, PIB/PDMS bicomponent networks are suitable for implant applications.
A planar electric vehicle with differential steering and a plantar command (2011)

This paper focuses on a new electric and compact vehicle with a differential steering and a sensitive plantar as driving command. The mechanical, electronic and software architecture are presented. A special focus is given to the sensitive surface of the vehicle chassis which allows the user to drive the vehicle by unbalancing his or her center-of-gravity (COG). The design of the plantar is herein outlined: the electronic system is described and the algorithm to estimate the COG position is proposed. Some experimental results about the sensitive plantar are reported.
Elevated Expression of miR302-367 in Endothelial Cells Inhibits Developmental Angiogenesis via CDC42/CCND1 Mediated Signaling Pathways (2018)

Rationale: Angiogenesis is critical for embryonic development and microRNAs fine-tune this process, but the underlying mechanisms remain incompletely understood.
Enhanced Charge Injection Properties of Organic Field‐Effect Transistor by Molecular Implantation Doping (2019)

Organic semiconductors (OSCs) have been widely studied due to their merits such as mechanical flexibility, solution processability, and large-area fabrication. However, OSC devices still have to overcome contact resistance issues for better performances. Because of the Schottky contact at the metal-OSC interfaces, a non-ideal transfer curve feature often appears in the low-drain voltage region. To improve the contact properties of OSCs, there have been several methods reported, including interface treatment by self-assembled monolayers and introducing charge injection layers. Here, a selective contact doping of 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F<sub>4</sub> -TCNQ) by solid-state diffusion in poly(2,5-bis(3-hexadecylthiophen-2-yl)thieno[3,2-b]thiophene) (PBTTT) to enhance carrier injection in bottom-gate PBTTT organic field-effect transistors (OFETs) is demonstrated. Furthermore, the effect of post-doping treatment on diffusion of F<sub>4</sub> -TCNQ molecules in order to improve the device stability is investigated. In addition, the application of the doping technique to the low-voltage operation of PBTTT OFETs with high-k gate dielectrics demonstrated a potential for designing scalable and low-power organic devices by utilizing doping of conjugated polymers.
CATALYST STRUCTURE STUDIED BY A LABORATORY EXAFS FACILITY : Ru/Al2O3 (1986)

A laboratory EXAFS spectrometer is described which features the utilization of higher order reflections from curved dispersing crystal. With this spectrometer a sufficient performance for structural analyses are obtained in the high energy region up to about 25 keV. It was applied to structurally characterize two kinds of Ru/Al2O3 catalysts, prepared from RuCl3 and Ru3(CO)12, by the Ru K EXAFS, combined with H2 adsorption and EM observations. It was found that Ru metal particles of different sizes were formed depending on the starting material and the procedure. In the catalyst prepared from Ru3(CO)12, small metal particles, possibly consist of about 20 atoms, are formed. They are small enough to show a contraction of the nearest neighbor distance by 0.06 A.
Comparative Analysis of Control Plane Security of SDN and Conventional Networks (2018)

Software defined networking implements the network control plane in an external entity, rather than in each individual device as in conventional networks. This architectural difference implies a different design for control functions necessary for essential network properties, e.g., loop prevention and link redundancy. We explore how such differences redefine the security weaknesses in the SDN control plane and provide a framework for comparative analysis which focuses on essential network properties required by typical production networks. This enables analysis of how these properties are delivered by the control planes of SDN and conventional networks, and to compare security threats and mitigations. Despite the architectural difference, we find similar, but not identical, exposures in control plane security if both network paradigms provide the same network properties and are analyzed under the same threat model. However, defenses vary; SDN cannot depend on edge based filtering to protect its control plane, while this is arguably the primary defense in conventional networks. Our concrete security analysis suggests that a distributed SDN architecture that supports fault tolerance and consistency checks is important for SDN control plane security. Our analysis methodology may be of independent interest for future security analysis of SDN and conventional networks.
XMCD Study of Epitaxial Magnetite Ultrathin Film on MgO(100) (2015)

The spin and orbital magnetic moments of the Fe3O4 epitaxial ultrathin film synthesized by plasma assisted simultaneous oxidization on MgO(100) have been studied with X-ray magnetic circular dichroism (XMCD). The ultrathin film retains a rather large total magnetic moment, i.e. (2.7+-0.15) uB/f.u., which is ~ 70% of that for the bulk-like Fe3O4. A significant unquenched orbital moment up to (0.54+-0.05) uB/f.u. was observed, which could come from the symmetry breaking at the Fe3O4/MgO interface. Such sizable orbital moment will add capacities to the Fe3O4-based spintronics devices in the magnetization reversal by the electric field.
