Advanced 3D Video Object Synthesis Based on Trilinear Tensors (2006)

In this paper an advanced method to synthesize 3D video objects is presented. Firstly, the knowledge about the implicit scene geometry is determined by a sparse set of point correspondences. Additionally an accurate camera calibration based on Zhangs method [1] and model is carried out. With the help of matching constraints obtained from epipolar geometry a dense disparity map is estimated using a modification of Birchfield and Tomasi’s pixel-to-pixel stereo algorithm [2]. Using these information we synthesize novel views. The mapping method we employ is called trifocal transfer and based upon the usage of trilinear tensors introduced by Shashua and Avidan [3]. Our synthesis method avoids the issue of indirect view specification and allows the user to move freely in space. The whole system chain is designed for future real-time TV applications. A modular software system we call ReVOGS (Realistic Video Object Generations System) [4] is the base for high level applications. We conclude the paper with an outlook of future system improvements.
Carvedilol and spirulina may provide important health protection to smokers and other nicotine addicts: a call for pertinent research. (2015)

Nicotine and soluble semi-stable aldehydes and ketones in cigarette smoke are key mediators of the elevated risks for vascular disease, cancer, and chronic obstructive pulmonary disease observed in smokers. Nicotine, via sympathetic stimulation, increases risk for both vascular disease and cancer. Comprehensive suppression of sympathetic activity with the well-tolerated drug carvedilol, which inhibits betal 1, beta2 and alphal adrenergic receptors, may be protective to smokers and other nicotine addicts. The soluble aldehydes and ketones in tobacco smoke appear to exert their adverse effects through activation of NADPH oxidase complexes in vascular tissues and in the lungs. The phytochemical phycocyanobilin (PhyCB), richly supplied by the edible cyanobacterium spirulina, in studies on rodents and in human cell cultures has shown the ability to safely mimic intracellular bilirubin's physiological role as an inhibitor ofNADPH oxidase activity. It therefore may have potential for mitigating the pro-oxidative effects of tobacco smoke aldehydes and ketones. Joint administration of carvedilol and spirulina merits exploration as a strategy for moderating the pathogenic impact of smoking in chronic tobacco users who either fail to quit or refuse to try cessation of tobacco. Carvedilol may be appropriate for those who manage a nicotine addiction in other ways (smokeless tobacco, e-cigarettes, nicotine gum). Further clinical studies to evaluate the impact of carvedilol on cardiovascular risk factors in nicotine addicts, and rodent studies to assess markers of lung inflammation in smoke- exposed rodents fed PhyCB, are recommended.

Uptake and metabolism of N 5 -formyltetrahydrofolate by L1210 leukemia cells. (1972)

N 5-Formyltetrahydrofolate was accumulated by L1210 cells by a temperature-dependent process. Accumulation of intracellular radioactivity was inhibited by p -chloromercuribenzoate, iodoacetate, fluoride ion, and ouabain. The rate of influx of N 5-formyltetrahydrofolate was decreased by the presence of methotrexate (MTX) or 5-methyltetrahydrofolate but by only high concentrations of folic acid. Radiolabel, accumulated by the L1210 cells from radiolabeled 5-formyltetrahydrofolate (f-FH4), was displaced by 5-methyltetrahydrofolate and MTX. No significant displacement of radioactivity was obtained when folic acid was tested at similar concentrations. Chromatography of accumulated intracellular radiolabels after incubation of the cells with radiolabeled f-FH4 demonstrated that the latter was metabolized rapidly to other folate coenzymes. The efflux of MTX was increased by the addition of f-FH4 to the media.

These findings suggest that f-FH4 transport into the L1210 cells is carrier mediated and that the cellular metabolism of this compound is rapid. This carrier system appears to be utilized also by MTX and 5-methyltetrahydrofolate and, to a lesser extent, by folic acid. Additional mechanisms by which f-FH4 reverses the action of MTX (namely, competition for uptake and enhancement of MTX efflux) are suggested by these studies.
Design of Ultra-Low Power Biopotential Amplifiers for Biosignal Acquisition Applications (2012)

Rapid development in miniature implantable electronics are expediting advances in neuroscience by allowing observation and control of neural activities. The first stage of an implantable biosignal recording system, a low-noise biopotential amplifier (BPA), is critical to the overall power and noise performance of the system. In order to integrate a large number of front-end amplifiers in multichannel implantable systems, the power consumption of each amplifier must be minimized. This paper introduces a closed-loop complementary-input amplifier, which has a bandwidth of 0.05 Hz to 10.5 kHz, an input-referred noise of 2.2 μ Vrms, and a power dissipation of 12 μW. As a point of comparison, a standard telescopic-cascode closed-loop amplifier with a 0.4 Hz to 8.5 kHz bandwidth, input-referred noise of 3.2 μ Vrms, and power dissipation of 12.5 μW is presented. Also for comparison, we show results from an open-loop complementary-input amplifier that exhibits an input-referred noise of 3.6 μ Vrms while consuming 800 nW of power. The two closed-loop amplifiers are fabricated in a 0.13 μ m CMOS process. The open-loop amplifier is fabricated in a 0.5 μm SOI-BiCMOS process. All three amplifiers operate with a 1 V supply.

Classification of urban environments in SAR images: a fuzzy clustering perspective (1998)

Fuzzy clustering algorithms are used for the interpretation of high resolution SAR images of urban environments. The idea is to define a pyramidal procedure suitable for the characterization first of more different environments (for instance, green areas, streets, and buildings). This rough analysis is then followed by more oriented fuzzy clustering tools, devoted to the extraction of more details: in this paper a modified fuzzy Bough transform is introduced and used to group pixels classified as pixels in consistent straight lines.
Improvement of the reproduced output of Co-Cr thin film media by insertion of very thin soft magnetic underlayer (1989)

In order to improve the reproduced output of a Co-Cr perpendicular magnetic recording medium, a very thin ( approximately 10 nm) soft magnetic underlayer such as a Permalloy film was inserted between the recording layer and the substrate. An evaluation using a ring-type head showed that the reproduced output of the Co-Cr medium was greatly increased by the underlayer without any deterioration in its high-density recording characteristics. The increase is attributed to the decrease of the demagnetizing field acting on the recorded magnetization, which is caused by the establishment of horseshoe magnetization modes in the vicinity of recording transition regions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Inside Cover: Distance‐Independent DNA Charge Transport across an Adenine Tract (Angew. Chem. Int. Ed. 30/2007) (2007)

DNA-mediated charge transport across adenine tracts was monitored by using a fast radical probe that is part of the bridge (N6-cyclopropyladenine, blue). As described by J. K. Barton and co-workers in their Communication on page 5731 ff., this trap, placed at each base across the A tract, is oxidized by the distal rhodium photooxidant (orange) with equal yield over a distance of 5 nm. These results are consistent with complete charge delocalization across the DNA bridge.

Mechanical properties of the ventricle during systole. (1980)

The systolic mechanical properties of the ventricular chamber, such as its volume elasticity and apparent viscosity or resistance, provide a useful framework for studying ventricular contraction. During systole, elasticity describes the dependence of pressure generated by the ventricle on chamber volume, while resistance describes changes in pressure related to the rate of ejection. Elastic stiffness increases throughout contraction and is sensitive to changes in inotropic state. Resistance also increases during contraction in parallel with ventricular pressure, but changes in inotropic state do not alter the relation between resistance and pressure. These two mechanical properties offer an insight into the performance of the ventricle as a pump; hence, they may be useful in assessing changes in pump function. This review examines several different approaches to the measurement of elasticity and resistance during systole: one approach lumped all the mechanical properties into a mean value expressed as an average impedance; another focused on elasticity, particularly the maximum elasticity achieved at end-systole; a third approach examined elasticity and resistance at high frequencies of volume oscillation; and the final method utilized a flow-pulse technique to study the variations in both elasticity and resistance throughout systole.
Nonlinear Mode Analysis and Optimization of a Triple-Push Oscillator (2008)

The triple-push oscillator architecture is an attractive application of a three element coupled oscillator array for high frequency signal generation. The desired solution to combine the power at the third harmonic and reject the first and second harmonics requires a 120 phase shift among the system elements. However, depending on the coupling strength and delay between the oscillators, the phase distribution varies, giving rise to different operating modes. Harmonic balance analysis is used to trace these multiple coexisting modes and their stability is investigated using envelope transient simulation. A design methodology is presented where optimum coupling parameters guarantee the operation of the system in the desired mode. A 13.8 GHz triple push oscillator is fabricated, and the various modes are investigated verifying the analysis.
The elevated temperature mechanical properties of silicon nitride/boron nitride fibrous monoliths (1998)

A unique, all-ceramic material capable of non-brittle fracture via crack deflection has been characterized from 25$\sp\circ$C through 1400$\sp\circ$C. This material, called fibrous monoliths (FMs), was comprised of unidirectionally aligned 250 $\mu$m diameter cells of silicon nitride surrounded by 10 $\mu$m thick cell boundaries of boron nitride. Six weight percent yttria and two weight percent alumina were added to the silicon nitride to aid in densification. TEM experiments revealed that the sintering aids used to densify the silicon nitride cells were migrating into the boron nitride cell boundary during hot-pressing and that a fine network of micro-cracks existed between basal planes of boron nitride. Elevated temperature four point bending tests were performed on fibrous monolith ceramics from room temperature through 1400$\sp\circ$C. Peak strengths of FMs averaged 510 MPa for specimens tested at room temperature through 176 MPa at 1400$\sp\circ$C. Work of fractures ranged from 7300 J/m$\sp2$ to 3200 J/m$\sp2$ under the same temperature conditions. The interfacial fracture energy of boron nitride, $\Gamma\sb{\rm BN}$, as a function of temperature has been determined using the Charalambides method. The fracture energy of boron nitride is approximately 40 J/m$\sp2$ and remained constant from 25$\sp\circ$C through 950$\sp\circ$C. A sharp increase in $\Gamma\sb{\rm BN}$, to about 60 J/m$\sp2$, was observed at 1000$\sp\circ$C-1050$\sp\circ$C. This increase in $\Gamma\sb{\rm BN}$ was attributed to interactions of the crack tip with the cell boundary glassy phase. Subsequent measurements at 1075$\sp\circ$C indicated a marked decrease in $\Gamma\sb{\rm BN}$ to near 40 J/m$\sp2$ before plateauing at 17-20 J/m$\sp2$ in the 1200$\sp\circ$C-1300$\sp\circ$C regime. The Mode I fracture toughness of silicon nitride was also determined using the single edge precracked beam method as a function of temperature. The He and Hutchinson model relating crack deflection at an interface to the Dundurs' parameter was applied to the current data set using the temperature dependent fracture energies of the boron nitride and the silicon nitride. A more refractory fibrous monolith was fabricated in an effort to extend the high temperature properties of SN/BN fibrous monoliths. Only 4 wt.% yttria was added to the silicon nitride to aid in densification. The presence of residual carbon following binder burnout was proposed to be responsible for the formation of melilite, a phase known to undergo severe oxidation between 900$\sp\circ$C-1100$\sp\circ$C. When residual carbon was removed prior to hot-pressing with a post-binder burnout heat treatment at 400$\sp\circ$C in air this phase was not present. A room temperature strength of 553 MPa and a work of fracture of 6700 J/m$\sp2$ was observed. A strength of 293 MPa was measured at 1400$\sp\circ$C.
Improved separation and quantitative determination of hydrocarbon types in gas oil by normal phase high‐performance TLC with UV and fluorescence scanning densitometry (2003)

Abstract Improved methods for separation and quantitative determination of hydrocarbon types from gas oil have been developed, which were based on high‐performance thin‐layer chromatography with ultraviolet and fluorescence scanning densitometry using horizontal elution. One of the methods allows the separation, detection, and determination of alkanes and naphthenes to be carried out, using berberine‐impregnated silica gel HPTLC plates, elution with n ‐hexane, and berberine‐induced fluorescence detection at 365 nm. Another developed method allows total aromatics to be determined using silica gel HPTLC plates by elution with n ‐hexane and acetone, and UV detection. In turn, PACs over three aromatic rings can be determined on either silica gel or caffeine‐impregnated silica gel HPTLC plates, elution with n ‐hexane, and selective detection using native fluorescence at 365 nm. Concentrations lower than 5 wt% can be determined using this technique. In addition, a technique for an efficient, baseline‐resolved separation of a gas oil according to the number of aromatics rings (mono + di‐, tri‐, and polyaromatic compounds with more than three rings) is presented here. This technique involves a multistep elution on a mixed (silica gel and caffeine‐impregnated silica gel HPTLC plate) using a counter‐elution device, and UV detection.
Exploring display factors that influence co-located collaboration: angle, size, number, and user arrangement (2005)

With recent advances in display technologies, co-located collaborators now have a number of viable options when choosing technology to incorporate into their face-to-face work activities. Co-located CSCW solutions have been explored for desktop computers, wall displays, tabletop displays, and networked devices including laptops and PDAs. Deciding which display technology is appropriate for a given situation requires an understanding of the impact of the underlying dimensions of the display technologies on co-located collaborative interactions. This paper presents a series of exploratory field studies that explore four factors of physical display technology: display angle, user arrangement, display size, and number of displays. The results from this work provide insights into the strengths and weaknesses of these various display factors, which can help system designers make informed choices regarding display technology. 1
High-Rate Modulation Codes for Reverse Concatenation (2007)

We present a reverse concatenation (RC) architecture using Reed-Solomon (RS) error-correction codes (ECCs). The scheme employs very-high-rate pre-RS modulation codes followed by RS parity symbol insertion. The very-high-rate modulation codes in the RC scheme, which facilitate timing recovery and automatic gain control and reduce the detector path memory, are of the same type as the modulation codes that have been used in generalized partial-response maximum-likelihood (PRML) detection systems
Incorporation of Privileged Structures into Bevirimat Can Improve Activity against Wild-Type and Bevirimat-Resistant HIV-1 (2020)

Two "privileged fragments", caffeic acid and piperazine, were integrated into bevirimat producing new derivatives with improved activity against HIV-1/NL4-3 and NL4-3/V370A carrying the most prevalent bevirimat-resistant polymorphism. The activity of one of these, 18c, was increased by 3-fold against NL4-3 and 51-fold against NL4-3/V370A. Moreover, 18c is a maturation inhibitor with improved metabolic stability. Our study suggested that integration of privileged motifs into promising natural product skeletons is an effective strategy for discovering potent derivatives.
Influence of Thaxtomins in Different Combinations and Concentrations on Growth of Micropropagated Potato Shoot Cultures (2006)

Plant-pathogenic Streptomyces species produce a variety of different phytotoxic 4-nitroindol-3-yl-containing 2,5-dioxopiperazines (thaxtomins) that induce scab symptoms on potato tubers (Solanum tuberosum). The possible mutual synergistic or antagonistic effects of thaxtomins are unknown. Modified methodology using column chromatography allowed the purification of thaxtomin A in large quantities (27 mg, HPLC purity of 97%). Thaxtomin A ortho isomer, thaxtomin B, and C-14 deoxythaxtomin B (thaxtomin D) were also purified. All four compounds induced similar symptoms of reduced root and shoot growth, root swelling (10-200 ppb), or necrosis (200-1000 ppb) on micropropagated in vitro cultures of potato. The scab-resistant potato cvs. Sabina and Nicola were more tolerant to thaxtomins than was the scab-susceptible cv. Matilda. Thaxtomins applied in combinations showed additive effects but no synergism, whereas thaxtomins A and B displayed antagonism with thaxtomin A ortho isomer.
Internal quality control of the urinary sediment light microscopy using home-brew control materials (2014)

Since there is wide interobserver variabilities in microscopic urinary sediment evaluation, quality control programs for urinary sediment test using control materials are warranted in Japan. We performed internal quality control using home-brew control materials and cross-checking of urinary sediment tests by the three technologists including two experts and one newcomer. Variabilities among the three technologists in counting red blood cell (RBC), white blood cell (WBC), and casts were found to be improved as early as five days after the start of quality control particularly in the newcomer. Half a year later, coefficients of variation of the three technologists in counting these components were all about ten percent, which were lower than those observed in the initial examination. In the cross-checking of urinary sediments, more than 93% of the results of RBC and WBC and 84% of the results casts were reported within one lank difference. The rare components including waxy cast, atypical cell, dysmorphic RBC, Trichomonas vaginalis were detected similarly by the three technologists. Thus, internal quality control of urinary sediment tests using home-brew control materials and cross-checking among medical technologists is useful for standardization of urinary sediment tests and training of a newcomer in a clinical laboratory.
Maternal anti-protein Z antibodies in pregnancies complicated by pre-eclampsia, SGA and fetal death (2009)

(1) Patients with SGA neonates have a higher median plasma concentration of IgG APZ-AB than normal pregnant women, or patients with PE or FD; and (2) maternal plasma IgM APZ-AB concentration >90th percentile was associated with vascular placental lesions in patients with PE, but not in those with an SGA neonate, suggesting that in a subset of patients, these antibodies can be associated with abnormal placentation and pregnancy complications.

Performance Measures for Frame Synchronization Techniques (2006)

We study sequential frame synchronization based on markers (or sync words), where the received samples are observed over a window of length equal to the marker length. A decision variable is derived over the observation window. A marker is declared if the decision variable exceeds a threshold; otherwise the observation window is time-shifted by one sample. This detection strategy can be characterized by the probabilities of false alarm and of correct detection, usually represented in terms of the Receiver Operating Characteristic (ROC). However, once the detector (and hence its ROC) is given, it is crucial from a design perspective to select an optimal operating point on the ROC. In this paper we propose a general framework to connect the ROC to the performance of frame synchronization in terms of the probability of correct acquisition in an arbitrarily long time period, valid both for constant and variable length frames. This framework can also be used to compare different marker detectors for frame synchronization. I. INTRODUCTION
Neisseria gonorrhoeae-induced transactivation of EGFR enhances gonococcal invasion (2011)

Neisseria gonorrhoeae, the causative agent of the sexually transmitted infection gonorrhoea, adheres to and invades into genital epithelial cells. Here, we investigate host components that are used by the bacteria for their entry into epithelial cells. We found that gonococcal microcolony formation on the surface of HEC-1-B cells disrupted the polarized, basolateral distribution of both epidermal growth factor receptor (EGFR) and ErbB2, a related family member, and induced their accumulation under the microcolonies at the apical membrane. Gonococcal infection increased EGFR and ErbB2 phosphorylation. The EGFR kinase inhibitor, AG1478, reduced gonococcal invasion by 80%, but had no effect on adherence or the recruitment of EGFR and ErbB2 to the microcolonies. Gonococcal inoculation upregulated the mRNA levels of several ligands of EGFR. Prevention of EGFR ligand shedding by blocking matrix metalloproteinase activation reduced gonococcal invasion without altering their adherence, while the addition of the EGFR ligand, HB-EGF, was able to restore invasion to 66% of control levels. These data indicate that N. gonorrhoeae modulates the activity and cellular distribution of host EGFR, facilitating their invasion. EGFR activation does not appear to be due to direct gonococcal binding to EGFR, but instead by its transactivation by gonococcal induced increases in EGFR ligands.
