Bone Mineral Density of Human Female Cervical and Lumbar Spines From Quantitative Computed Tomography (2005)

The present study failed to support the hypothesis that BMD of lumbar spine vertebrae is equivalent to its cranial counterparts. The lack of differences in BMD among the three lumbar vertebral bodies confirms the appropriateness of using L2, L3, or L4 in clinical or biomechanical situations. However, significant differences were found among different regions of the vertebral column, with the cervical spine demonstrating higher trabecular densities than the thoracic and lumbar spines. In addition, the present study found statistically significant variations in densities even among neck vertebrae.
Testosterone and Erectile Dysfunction (2008)

Aging is associated with a decline in several important health factors in men, including libido. Serum testosterone concentrations also decrease with age, and many age-related clinical features are closely associated with androgen deficiency, including erectile function (ED). Approximately 70% of ED is of organic origin, with the major risk factors being diabetes mellitus, hypercholesterolemia, smoking and chronic medical illnesses. These are also established risk factors for atherosclerosis, which is the predominant predisposing factor of vasculogenic ED. The introduction of phosphodiasterase-5 (PDE-5) inhibitors for the treatment of ED made a significant impact both in terms of clinical efficacy, and increasing the awareness of the condition. In spite of this, some patients fail to respond to PDE-5 inhibitors alone. Both animal and clinical studies indicate that testosterone therapy improves both erectile function and the response to PDE-5 inhibitors in patients with ED and hypogonadism. Indeed, interventional studies demonstrate that testosterone replacement therapy improves erectile function in hypogonadal men who have previously failed to respond to PDE-5 inhibitors alone. Furthermore, it has been demonstrated that the full therapeutic potential of PDE5 inhibitors will only become manifest in a eugonadal state. Recent studies have demonstrated a close relationship between testosterone and ED and suggest that testosterone therapy may be a valuable option for an increasing number of affected men. European guidelines recommend that all men presenting with ED should have their testosterone concentrations measured.
Multi-Vehicle Cooperative Control Flight Test (2006)

During the spring and summer of 2005, the autonomous flight systems laboratory at the University of Washington and Boeing St. Louis developed and flight tested control software for the Boeing multi-vehicle UAV Testbed. The goal of this collaboration was to demonstrate the ability of a team of UAVs to autonomously allocate a set of targets among the team and fly to the targets while avoiding designated areas. A distributed architecture was used maximizing the benefits of increased autonomy in the areas of task allocation and path planning. The real-time decision making component consists of the evolution-based cooperative planning system (ECoPS) developed under DARPA funding. The approach was demonstrated in simulations and in a flight test at Fort Leonard Wood, Missouri
Optimization of cone target geometry for fast ignition (2007)

Electron energy characteristics generated by the irradiation of ultraintense laser pulses onto solid targets are controlled by using cone targets. Two parameters characterizing the laser-cone interaction are introduced, which are cone angle and the ratio of the laser spot size to the cone tip size. By changing these parameters, the energy absorption rate, laser irradiance at the cone tip, and electron acceleration at the cone tip and side wall are controlled. The optimum cone targets for fast ignition are 30° cone angle with double-cone geometry, and a tip size comparable to the core size, with the irradiation of a laser pulse with a spot size of about four times the cone tip size. Cone targets have the possibility to enhance the maximum energy of laser-accelerated protons by using a smaller angle cone depending on the laser f-number.
Performance of smart antennas with adaptive combining at handsets for the 3GPP W-CDMA system (2002)

We present the performance gain of dual smart antennas with adaptive combining at handsets for the 3GPP W-CDMA system. The adaptive algorithm based on the normalized least-mean-square (N-LMS) algorithm is employed, in which antenna weights are recursively obtained. To obtain the channel profile, we adopted the GBSB (geometrically based single bounce) elliptical and circular models. The simulation results show that the dual smart antenna system with adaptive combining performs better than a single antenna system and its performance gain is 3.3 dB for the GBSB elliptical model at BER of 5/spl times/10/sup -2/ and 5.5 dB for the GBSB circular model. The higher performance gain is achieved as the mobile velocity decreases.
Distal Venous Arterialization for Limb Salvage (2002)

The reperfusion of an ischemic limb in the absence of suitable target artery remains a formidable task. The authors report a case of an ischemic limb in patient whose distal arteries were identified intraoperatively as unsuitable for conventional revascularization. A distal arteriovenous fistula was created between the already arterialized in situ greater saphenous vein conduit and the inframalleolar superficial venous system of the foot. The flow through the superficial venous system salvaged the limb and continues to perfuse the foot 4 years post-operatively with resolution of rest pain.
Pyrazole analogues of the bispyrrolecarboxamide anti-tumour antibiotics: synthesis, DNA binding and anti-tumour properties. (1991)

Four bispyrazole compounds have been prepared as potentially more stable analogues of the DNA minor groove binding polypyrrole compounds netropsin and distamycin, which are susceptible to oxidative breakdown. These compounds bind less strongly to DNA, and show much lower specificity for binding to AT-rich DNA sequences in comparison with distamycin. N.m.r. studies show that two of these compounds cause a downfield shift of the DNA imino proton resonances on interaction with the oligonucleotide d(ATATATATAT)2, suggesting that these isomers can adopt low-energy conformations similar to that shown by distamycin in its DNA minor groove binding site. The benzoic acid mustard analogue of one of the minor groove binding bispyrazoles was prepared, and showed in vitro cytotoxicity comparable with that of the previously-reported distamycin mustard, but only a low level of activity in vivo.
Biological control of vertebrates-a review, and an assessment of prospects for Malaysia. (1985)

Manipulation of predators and parasites against vertebrate pests had not generally been effective. The literature recorded only one clear cut success, the myxomatosis disease of rabbits. Among possible reasons were that natural enemies were insufficiently density dependent to control populations, that vertebrates had complex and adaptable physiology, that they could rapidly reproduce to meet continuous losses or restore numbers after decimation, and relatively small numbers (compared with insects for example) could still do serious harm. Predators might only remove surplus animals above an environment support level, but sometimes there was evidence that they established lower equilibrium levels. Most predators had a non-specific diet and could have severe side-effects in new localities, especially if there were no effective native predators -e.g. island ecosystems. The few recorded importations involved small carnivores against introduced rats and rabbits, e.g. the Indian mongoose to Caribbean and Pacific Islands, and mustelids to Australia and New Zealand. All attacked native animals and poultry, but had little effect on the target species. Predator numbers appeared more affected by prey than vice versa, e.g. if rats were controlled by baiting in Malaysian oil palms, snakes tend to disappear. Generalist predators with alternative prey sometimes appeared capable of restraining increase of one particular prey species. It might be possible to buffer predator numbers by supporting them, or altering the environment, e.g. cats on farms by feeding, or owls in oil palms by giving nesting sites. Parasites (diseases) might carry risks for non-target species, including man. Naturally-occurring forms might flare up when vertebrate host populations built up. Evidence of their effect was usually equivocal, although myxomatosis had greatly reduced rabbit numbers. Baits employing acute pathogens had success against rats. In Malaysia, the coccidian Sarcocystissingaporensis, which required phythons as an intermediate host, was lethal to rats. Also, rats in the field might be heavily infected by helminths. However, no dramatic achievement in biological control of vertebrates could be expected but possibilities for rats, Malaysia's most serious vertebrate pests, were worth pursuing, especially in the context of recent reports of warfarin resistance. There was a need of more concerted effort which could be part of a greater national focus biologica
Anisotropic mobility in large grain size solution processed organic semiconductor thin films (2008)

The hollow pen method for writing thin films of materials from solution is utilized to deposit films of 6,13-bis(tri-isopropylsilylethynyl) pentacene (TIPS pentacene) onto SiO2 surfaces with pre-patterned source/drain gold contacts. We demonstrate that large domains are obtained for TIPS pentacene films deposited from 0.5–4.0wt% solutions with toluene. Crystalline grains with (001) orientation are observed to grow with sizes that can exceed 1mm along the writing direction. A preferred azimuthal orientation is also selected by the process, resulting in anisotropic field effect transistor mobility in the films.
Iterative Feedback Tuning (IFT) of Hard Disk Drive Head Positioning Servomechanism (2007)

Hard disk drive (HDD) is a mass produced item so are its components including the actuator used for head positioning servomechanism. Transfer characteristics of these actuators vary within a tolerance limit and a nominal model representing the family of actuators is used for controller design. Equally good performance is not possible for all actuators with the designed controller. However, as the demand for performance of the disk drive servomechanism continues to grow higher to meet the requirements for higher storage capacity of HDD, performance of the servo controller becomes more crucial. Furthermore, wear and tear of the components causes degradation of performance over time. These issues demand the use of good on-line tuning of servo controller. This paper explores the possibility of using Iterative Feedback Tuning (IFT) on HDD servomechanism. Enhancement of performance with IFT is demonstrated using simulation and experimental results.
A Rapid, Specific Membrane Filtration Procedure for Enumeration of Enterococci in Recreational Water (1998)

A two-step membrane filter (MF) method with mE medium, upon which the membrane must be incubated for 48 h and then transferred to a substrate medium to differentiate enterococci, is recommended by the U.S. Environmental Protection Agency to measure enterococci in fresh and marine recreational waters. The original mE medium was modified by reducing the triphenyltetrazolium chloride from 0.15 to 0.02 g/liter and adding 0.75 g of indoxyl beta-D-glucoside per liter. The new MF medium, mEI medium, detected levels of enterococci in 24 h comparable to those detected by the original mE medium in 48 h, with the same level of statistical confidence. In addition, the use of mEI medium eliminated the need to transfer the membrane to a substrate medium to differentiate enterococci from other genera of the fecal streptococcal group. Colonies from mEI medium were examined to determine the rates of false-positive and false-negative occurrences. mEI medium had a false-positive rate of 6.0% and a false-negative rate of 6.5%. Interlaboratory testing of the MF method with mEI medium demonstrated that the relative reproducibility standard deviations among laboratories ranged from 2.2% for marine water to 18.9% for freshwater. The comparative recovery studies, specificity determinations, and multilaboratory evaluation indicated that mEI medium has analytical performance characteristics equivalent to those of mE medium. The simplicity of use and decreased incubation time with mEI medium will facilitate the detection and quantification of enterococci in fresh and marine recreational waters.
CHARACTERIZATION OF A SPRAY FROM AN ULTRASONICALLY MODULATED NOZZLE (1997)

The effects of ultrasonic modulation on liquid spray characteristics in a pressure-swirl nozzle at part load have been examined experimentally. The spray characteristics include discharge coefficient, spray appearance, spray cone angle, and spray patternation. An optical visualization technique is used to investigate the spray appearance and the spray cone angle. Spray patternation experiments are conducted both with a physical patternator and with the liquid planar laser-induced fluorescence (LPLIF) technique. The results show that the piezoelectric driver in the atomizer contains several discrete resonant frequencies. At these resonant frequencies, the ultrasonic modulation improves spray development and spray patternation, but has little effect on discharge coefficient and spray cone angle. The improvement is particularly prominent at a part-load injection pressure. Apparently, the ultrasonic modulation increases the perturbation of the liquid inside the nozzle and produces a condition for early disintegration of the liquid sheet issuing from the nozzle. Through this improved atomization, the ultrasonically modulated nozzle may improve the combustion process when engines are at part load or idle condition.
The Infrared Spectra of Quasars - A Luminosity Dependence (1987)

The IR-optical-UV continua of quasars are often represented by two components: (i) a flat spectrum component dominating in the optical-UV (the “Big Bump”) and sometimes attributed to thermal radiation from an accretion disk with temperatures of about 20000 to 40000 K - we will call it the “disk” component - and (ii) a near IR component characterized by a steep rise, α ∼ 1 for λ > 1 μm, often thought to be a synchrotron spectrum - an extrapolation of the cm or mm wavelength radio spectrum - although some have preferred an explanation in terms of thermal re-radiation of the ionizing continuum by hot dust (e.g., Hyland and Allen 1982, Neugebauer et al. 1979).
Stationary-frame generalized integrators for current control of active power filters with zero steady-state error for current harmonics of concern under unbalanced and distorted operating conditions (2002)

The paper proposes the concepts of integrators for sinusoidal signals. A proportional-integral (PI) current controller using stationary-frame generalized integrators is applied for current control of active power filters. Zero steady-state error for the concerned current harmonics is realized, with reduced computation, under unbalanced utility or load conditions. Designing of the PI constants, digital realization of the generalized integrators, as well as compensation of the computation delay are studied. Extensive test results from a 10-kW prototype are demonstrated.
Variation in and among early life history traits of laboratory-reared winter flounder Pseudo-pleuronectes americanus (1988)

We analyzed variation in and among early Life history traits of laboratory-reared winter flounder Pseudopleuronectes americanus. We measured lengths and ages at hatching and metamorphosis, lengths at 2 wk intervals through the larval period and into the first 3 wk of the juvenile period, and after 23 wk of juvenile life. Variation in traits was quantified and compared by the coefficient of variation (CV = SD/mean). CVs for lengths-at-ages increased from hatching (0.03) to an asymptotic value of = 10 % by 2 to 4 wk after first feeding. There were 2 peaks in variation in lengths-at-age during the early life history; one a t Week 4 (the approximate midpoint of the larval period) and another Week 10 (during the latter portion of the metamorphic window and early juvenile life). These may reflect commensurate changes observed in growth rates. Variation In length at hatching and metamorphosis was relatively low (3.0 and 5.3 % , respectively), and less than variation in age. Lengths-at-transitions were also less variable than lengths at fixed ages during the larval and juvenlle periods. These findings imply a target size for life period transitions. Length and age a t metamorphosis were positively correlated, as were sequential average lengths calculated from fortnightly measures. Length and a g e a t metamorphosis, and growth and developmental rates through the entire larval period, were positively correlated when calculated from the bivarlate measure of individuals. The pattern of variation in and correlations among early llfe history traits established in the larval period appears to propagate through metamorphosis and into early juvenile life. The population consequences of these associations, and their potential use in analyzing the results of early Life history studies, are discussed.
Lignin monomer composition is determined by the expression of a cytochrome P450-dependent monooxygenase in <i>Arabidopsis</i> (1998)

The phenylpropanoid pathway provides precursors for the biosynthesis of soluble secondary metabolites and lignin in plants. Ferulate-5-hydroxylase (F5H) catalyzes an irreversible hydroxylation step in this pathway that diverts ferulic acid away from guaiacyl lignin biosynthesis and toward sinapic acid and syringyl lignin. This fact led us to postulate that F5H was a potential regulatory step in the determination of lignin monomer composition. To test this hypothesis, we have used Arabidopsis to examine the impact of F5H overexpression. Arabidopsis is a useful model system in which to study lignification because in wild-type plants, guaiacyl and syringyl lignins are deposited in a tissue-specific fashion, while the F5H-deficient fah1 mutant accumulates only guaiacyl lignin. Here we show that ectopic overexpression of F5H in Arabidopsis abolishes tissue-specific lignin monomer accumulation. Surprisingly, overexpression of F5H under the control of the lignification-associated cinnamate-4-hydroxylase promoter, but not the commonly employed cauliflower mosaic virus 35S promoter, generates a lignin that is almost entirely comprised of syringylpropane units. These experiments demonstrate that modification of F5H expression may enable engineering of lignin monomer composition in agronomically important plant species.
Pancreatic cancer cell and microparticle procoagulant surface characterization (2011)

Advanced pancreatic cancer is associated with a high risk of patients developing venous thromboembolism. This increased risk is thought to be tumour-driven and associated with tissue factor (TF) and microparticles. The aim of this study was to investigate the role of TF and phospholipid expression in the procoagulant properties of pancreatic cell lines and microparticles. Pancreatic cancer cell lines (MIA-PaCa-2, ASPC-1 and CFPAC-1) were assessed for expression of TF and microparticle release. Procoagulant potential was determined by a prothrombin time assay. Cell surface expression of TF was highest in CFPAC-1, with low expression on ASPC-1 and little/no expression on MIA-PaCa-2. Clotting time (CT) was cell number and TF-dependent (P < 0.001). Blocking of TF resulted in slower CT for CFPAC-1 and ASPC1 and prevented clotting in MIA-PaCa-2. Microparticles were shown to be procoagulant and the majority of procoagulant potential could be removed by passing cell-free media through a 0.1 μm filter. A dose-dependent CT was observed in both ASPC-1 and CFPAC-1 cell-free media. Furthermore, addition of duramycin prevented microparticle-supported coagulation. The data presented suggest a key role for cell and microparticle surface-expressed TF and phospholipids in coagulation and highlight duramycin-mediated disruption of clotting.
Expanding Assay Dynamics: A Combined Competitive and Direct Assay System for the Quantification of Proteins in Multiplexed Immunoassays (2008)

By combining a direct immunoassay with a competitive system, analytes present in widely varying concentrations can be quantified within a single multiplex assay. Introducing a second readout channel for analyte quantification is an effective tool for spot-to-spot normalization and helps to lower intraassay variation.
Towards a practical, secure, and very large scale online election (2003)

We propose a practical and secure electronic voting protocol for large-scale online elections. Our protocol satisfies a large set of important criteria that has never been put together in a single protocol before. Among all electronic voting schemes in the literature, Sensus, a security-conscious electronic voting protocol proposed by Cranor and Cytron (1997), satisfies most of our criteria. Sensus has been implemented and used in mock elections. However, Sensus suffers from several major drawbacks. For instance, we show that even if all voters follow the Sensus protocol honestly, some voters' votes may still be replaced with different votes without being detected. Our protocol overcomes these drawbacks.
Aggregating Atomic Clocks for Time-Stamping (2020)

A timestamp is a critical component in many applications, such as proof of transaction ordering or analyzing algorithm performance. This paper reports on a method called Verified Timestamping (VT) that improves the standard timestamp protocol. VT was developed at the National Institute of Standards and Technology (NIST) for use in algorithms where timestamp accuracy is critical. VT is an aggregation of the outputs from various atomic clocks to create a Timestamping Authority (TsA). The motivation for this research effort included malicious delay issues in Networks of Things [NIST SP 800-183] as well as race conditions associated with the inclusion of new blocks into blockchains. This paper presents the TsA design and the results of VT, which indicate that atomic clock aggregation is not only possible, but a viable means to produce higher integrity timestamps at the ms level of performance. Tests showed that this is sufficient to preserve event ordering, using only a conventional PC with no dedicated connection or specialized hardware.
