Dielectric Barrier Discharge Control and Flow Acceleration Enhancement by Diode Surface (2013)

The development of actuator methods for introducing momentum into flows near surfaces will have important applications for separation control, lift enhancement, and drag reduction. Due to the vast range of conditions encountered during flight, the ideal actuator should be robust, easily employed wherever actuation is needed, have a fast response time, have negligible power requirements, be flush mounted and provide effective actuation for a large range of flow fields. The offset surface dielectric barrier discharge actuator (SDBD) features many of these requirements, but the conventional sinusoidal or nanosecond pulsed SDBD is limited to relatively weak induced velocities that are unable to provide useful actuation of some flow fields. These limitations may be eliminated by a new type of dielectric barrier discharge, the semiconducting surface dielectric barrier discharge (SSDBD). This device operates with high repetition rate nanosecond pulses and suppresses velocity cancellation effects associated with backward breakdown by providing a return current path inside the surface itself. This new device is still in its infancy; however, initial measurements presented here demonstrate backward breakdown suppression.
Probing Influence of Mesophasic Transformation on Performance of Self-Emulsifying System: Effect of Ion (2012)

Self-emulsifying systems are mixtures of oils and surfactants, ideally isotropic, sometimes including cosolvents, which emulsify under conditions of gentle agitation, similar to those which would be encountered in the gastrointestinal tract. The process of self-emulsification has remained the center of attraction for most researchers. Controlled hydration of self-emulsifying systems shows formation of an intermediate gel phase which upon rupture forms an emulsion. Current work was undertaken to understand and explore the microstructural properties of intermediate gel phase which are believed to influence the performance (droplet size) of the final formulation. The effect of additives on microstructural properties of intermediate gel phase has also been investigated. Microstructural elucidation of hydrated samples of intermediate regimes was done by using techniques such as small angle X-ray scattering, differential scanning calorimetry and rheology. Samples from intermediate regimes showed formation of local lamellar structure which swelled with hydration. In the present work, the effect of addition of salt form of naproxen (sodium and potassium) and naproxen (base) on microstructural properties of intermediate regimes was investigated. Systems containing naproxen salts formed larger droplets whereas naproxen base formed smaller ones. Microstructural properties of intermediate lamellar structures were well correlated with performance of the final formulation. The current studies indicate that by controlling the properties of intermediate regimes optimized formulations with desired performance can be tailor-made.
<title>Why do color transforms work?</title> (1997)

Numerous papers have been written regarding techniques to translate color measurements from an RGB device into some standard color space. The papers seem to ignore the mathematical 'truth'...that the translation is impossible. Do these color transforms work, or under what conditions do they work, and what are the limitations. Why is it that they work. In this paper, light emitting diodes (LEDs) are viewed with a color video camera.It is seen that, for the spectra of LEDs, transforming from the camera color space the XYZ tristimulus space leads to very large errors. The problem stems from the fact that the RGB filter response are not a linear combination of XYZ responses. Next, it is shown that the transformation of CMYK halftones does not pose such difficulties.Here, it is found that a simple linear transform is relatively accurate, and some options to improve this accuracy are investigated. Several explanations are offered as to why transforms of CMYK are more accurate than transforms of LEDs. To determine which of the explanations is the most likely, linear transforms are applied to a variety of collections of colors.

Fluorescence lifetime-based sensing of sodium by an optode (2014)

We report a 1,2,3-triazol fluoroionophore for detecting Na(+) that shows in vitro enhancement in the Na(+)-induced fluorescence intensity and decay time. The Na(+)-selective molecule 1 was incorporated into a hydrogel as a part of a fiber optical sensor. This sensor allows the direct determination of Na(+) in the range of 1-10 mM by measuring reversible fluorescence decay time changes.
Computational study of anterior communicating artery hemodynamics before aneurysm formation (2012)

It is widely accepted that complexity in the flow pattern at the anterior communicating artery (AComA) is associated with the high rate of aneurysm formation in that location observed in large studies. A previous computational hemodynamic study showed a possible association between high maximum intraaneurysmal wall shear stress (WSS) at the systolic peak with rupture in a cohort of AComA aneurysms. In another study it was observed a connection between location of aneurysm blebs and regions of high WSS in models where blebs were virtually removed. However, others reported associations between low WSS and either rupture or blister formation. The purpose of this work is to study associations between hemodynamic patterns and AComA aneurysm initiation by comparing hemodynamics in the aneurysm and the normal model where the aneurysm was computationally removed. Vascular models of both right and left circulation were independently reconstructed from three-dimensional rotational angiography images using deformable models, and fused using a surface merging algorithm. The geometric models were then used to generate high-quality volumetric finite element grids of tetrahedra with an advancing front technique. For each patient, the second anatomical model was created by digitally removing the aneurysm. It was iteratively achieved by applying a Laplacian smoothing filter and remeshing the surface. Finite element blood flow numerical simulations were performed. It was observed that aneurysms initiated in regions of high and moderate WSS in the counterpart normal models. Adjacent or close to those regions, low WSS portions of the arterial wall were not affected by the disease.
Future of Care for Patients With Chronic Granulomatous Disease: Gene Therapy and Targeted Molecular Medicine (2018)

Chronic granulomatous disease is a rare and potentially fatal disorder of neutrophil function. Beyond current medical management and hematopoietic stem cell transplantation, new methods of gene therapy that use lentiviral vectors or gene editing might extend curative therapies to patients who lack a suitable transplantation donor while eliminating the risk of graft-versus-host disease. Furthermore, new therapies focused on altering the biology of phagolysosomes might offer novel targeted treatments for inflammatory complications in patients with chronic granulomatous disease.

Tardos Fingerprinting Codes in the Combined Digit Model (2011)

We formalize a new attack model for collusion secure codes, incorporating attacks on the underlying watermarking scheme as well as cut-and-paste attacks traditionally considered for collusion secure codes. We use this model to analyze the collusion resistance of two versions of the Tardos code, both for binary and nonbinary alphabets. The model allows us to consider different signal processing attacks on the content, namely the addition of noise and averaging attacks. The latter may result in content segments that have multiple watermarks embedded. We study two versions of the <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">$q$</tex></formula> -ary Tardos code in which the accusation method has been modified so as to allow for the detection of multiple symbols in the same content segment. We show that both variants yield efficient codes in the new model, parametrized for realistic attacker strengths.

Role of Human Cds1 (Chk2) Kinase in DNA Damage Checkpoint and Its Regulation by p53 (1999)

In response to DNA damage, mammalian cells adopt checkpoint regulation, by phosphorylation and stabilization of p53, to delay cell cycle progression. However, most cancer cells that lack functional p53 retain an unknown checkpoint mechanism(s) by which cells are arrested at the G(2)/M phase. Here we demonstrate that a human homolog of Cds1/Rad53 kinase (hCds1) is rapidly phosphorylated and activated in response to DNA damage not only in normal cells but in cancer cells lacking functional p53. A survey of various cancer cell lines revealed that the expression level of hCds1 mRNA is inversely related to the presence of functional p53. In addition, transfection of normal human fibroblasts with SV40 T antigen or human papilloma viruses E6 or E7 causes a marked induction of hCds1 mRNA, and the introduction of functional p53 into SV40 T antigen- and E6-, but not E7-, transfected cells decreases the hCds1 level, suggesting that p53 negatively regulates the expression of hCds1. In cells without functional ataxia telangiectasia mutated (ATM) protein, phosphorylation and activation of hCds1 were observed in response to DNA damage induced by UV but not by ionizing irradiation. These results suggest that hCds1 is activated through an ATM-dependent as well as -independent pathway and that it may complement the function of p53 in DNA damage checkpoints in mammalian cells.
Solvent effect on the solution, ionization, and structure of aminosulfonic acids (1988)

We have determined thermodynamic parameters for the solution and ionization in dimethylsulfoxide and water of four aminosulfonic acids: NH 2 (CH 2 ) n SO 3 H with n = 0,1, and 2, and NH 2 C 6 H 4 SO 3 H. Potentiometric and calorimetric methods were used. The solubilities of the four acids in Me 2 SO are either nearly equal to or lower than in water, but the enthalpies of solution are 15–40 kJ mol −1 more exothermic in Me 2 SO. The three aliphatic acids are much weaker (2.1 ≤ ΔpK a ≤ 5.5) in Me 2 SO than in water and their heats of ionization are some 30 kJ mol −1 more endothermic in Me 2 SO. The discussion of our results is based on comparisons with corresponding data for related substituted amines and ammonium ions, and sulfonic acids and sulfonate ions. We conclude that the four aminosulfonic acids are mostly present as zwitterions in Me 2 SO just as in water.
Photoreduction of Silver on Bare and Colloidal TiO2 Nanoparticles/Nanotubes:  Synthesis, Characterization, and Tested for Antibacterial Outcome (2007)

Silver nanoparticles of particle size around 15 nm were synthesized by following a simple and green methodology of photoreduction of silver nitrate (AgNO3) using bare titania and polyvinyl alcohol (PVA)-capped colloidal titanium dioxide nanoparticles/nanotubes under UV−vis light (λ = 365 nm). The synthesized pure TiO2 nanoparticles/tubes, Ag−TiO2 nanocomposites and PVA-capped colloidal Ag−TiO2 nanocomposites are characterized for their structure and morphology by X-ray diffraction (XRD) and transmission electron microscopy (TEM) and for their electronic structure by X-ray photoelectron spectroscopy (XPS). The antibacterial efficiency of all nanocomposites were investigated on Escherichia coli using standard procedures. The synthesized metal−metal oxide nanocomposites are shown to be very efficient toward destroying Gram negative bacteria Escherichia coli.
Temporal diffraction in a chirped-pulse amplification system (1995)

Pulse shaping has received considerable attention for manipulating ultrashort pulses. In most cases the pulse shaper is linear, i.e., the amplitude and/or phase masks do not depend on the intensity of the pulse. Recently, nonlinear pulse shapers—ones in which the pulse-shaping effect is a function of the laser intensity—have been demonstrated.1,2 Here we report nonlinear pulse shaping by using two chirped pulses propagating in a laser gain medium. The unique feature of our experiment is that we simultaneously resolve temporal and spectral behaviors of the pulses by using a spectrometer-streak-camera combination. We show that additional frequencies are generated as a result of nonlinear interaction in the gain medium, and the pulses that carry the new frequencies are those created by temporal diffraction as a result of pulse shaping.
Polarimetric target depth sensing in ambient illumination based on polarization-coded structured light (2017)

Depth sensing is a basic issue in three-dimensional computer vision, and structured light is one of the most prevailing methods for it. However, complex surroundings and strong ambient illumination are fairly unfavorable to depth sensing based on structured light. Complex surroundings increase computation overhead and require extra effort to be separated from the target object. Strong ambient illumination is unfavorable to the signal-noise ratio of structured light and, thus, increases the difficulty of decoding. In this paper, we propose that the polarization-coded structured light is capable of target enhanced depth sensing in ambient illumination. We present the polarimetric principle, an improved algorithm of polarization-coded structured light, and signal-noise-ratio analysis in ambient illumination. Experimental results show that polarization-coded structured light is efficient and robust for target depth sensing of a complicated environment. The polarization-coded structured light is promising to the target depth sensing in an outdoor scenario and industrial inspection.
Non‐clinical determinants of planned cesarean delivery in cases of term breech presentation in France (2007)

The variation in planned cesarean rates between maternity units was not associated with their structural characteristics, but was related to a characteristic specific to each centre, and, thus, suggests that despite the current guidelines in France, obstetricians have diverse opinions about the best mode of delivery for breech presentations.
Do decode-and-forward relaying protocols beat transmit diversity? (2010)

This paper addresses the question whether decode-and-forward relaying protocols can beat transmit diversity with respect to ε-outage capacity. We derive expressions of ε-outage capacity for transmit diversity, decode-and-forward, selective decode-and-forward, and incremental decode-and-forward. We demonstrate that the relaying protocols outperform transmit diversity in certain regions. Decode-and-forward is beneficial over transmit diversity when the relay is located close to the source. For selective decode-and-forward to beat transmit diversity, the relay should be placed between the source and the destination, but not too close to the source. The best performance is achieved by incremental decode-and-forward. The region in which this scheme is beneficial over transmit diversity is large. Moreover, as the region becomes smaller, the outage probability for the source-destination link becomes larger.
Inhibition of glycolysis modulates prednisolone resistance in pediatric acute lymphoblastic leukemia cells in vitro (2008)

1628 Treatment failure in pediatric acute lymphoblastic leukemia (ALL) can be caused by cellular resistance to some important classes of drugs used in therapy, such as glucocorticoids (e.g. prednisolone), L-asparaginase, Vinca alkaloids (e.g. vincristine) and anthracyclines (e.g. daunorubicin). However, the exact mechanisms that cause cellular resistance to these agents are still unknown. In order to obtain insight into the signal transduction routes that are involved in drug resistance in children with ALL, a microarray study was previously performed in our lab on precursor B-lineage leukemic patients [Holleman et al., N Engl J Med 2004]. Analysis of the gene expression profiles of 20 prednisolone resistant and 54 -sensitive precursor B-ALL cases revealed significant differences in the expression of genes associated with glucose metabolism (p≤0.0005). Expression levels of glyceraldehyde-3-phosphatedehydrogenase (GAPDH), carbonic anhydrase 4 (CA4) and glucose transporter 3 (GLUT3/SLC2A3) were higher in prednisolone resistant cells when compared to prednisolone sensitive leukemia cells (fold change = 1.26, 1.56 and 2.08 respectively). Therefore, several drugs that have been reported to affect glycolysis were tested for their ability to reverse resistance to glucocorticoids, using the in vitro MTT cytotoxicity assay. Treatment of the prednisolone-resistant cell lines Jurkat and Molt4 with 2-deoxyglucose (2-DG), lonidamine or 3-bromopyruvate increased the sensitivity to prednisolone and dexamethasone about ten-fold, while treatment of the prednisolone sensitive cell lines Tom-1 and RS4-11 had little or no effect. Importantly, the sensitizing effect of 2-DG on glucocorticoid resistance was not limited to cell lines, but was also observed in isolated primary leukemia cells from 7 of 11 patients tested. Interestingly, the synergistic effect of the glycolysis inhibitors was not found with other classes of antileukemic drugs (i.e., vincristine and daunorubicin). Together, these findings indicate the importance of the glycolysis pathway in steroid resistance in leukemia, and suggest that targeting this pathway is a viable strategy for modulating steroid-resistance in ALL.
Performance of an adaptive rate modem using quasi-analytic simulation techniques (1999)

The symbol error probability (SEP) of a digital signal processor implemented /spl pi//M M-ary differentially coherent phase-shift keying (MDPSK) modem, using quasi-analytical (QA) simulation techniques, is the subject of this investigation. We study M values of 4, 8, 16, 32, and 64 for use in a fast adaptive data rate mobile radio communication system. The proposed modulation scheme /spl pi//M-MDPSK, is a generalization of /spl pi//4 differentially coherent quadrature phase-shift keying, which is used in the North American time-division multiple-access wireless standard. A QA simulation approach is developed so that real system impairments can be studied without having to resort to lengthy Monte Carlo simulation. In particular, it is found that implementation losses, most notable at M=32 and 64, which result from practical transmit and receive filtering, and symbol timing error, can be largely overcome by using a fixed equalization filter and increased accuracy of symbol timing recovery. We focus on an additive white Gaussian noise channel since, in a fast adaptive rate system, the Doppler spread mobile channel is approximately Gaussian on short time intervals. However, the quasi-analytic technique developed here is directly extendable to a fast Rayleigh fading channel. Specifically, we find that for M=64, the inclusion of a fixed seven-tap zero forcing equalizer at the matched filter output, decreases the SEP degradation at P/sub e/=10/sup -4/ from 7.5 dB down to 0.24 dB. The symbol timing error using a finite-precision interpolator is held to within 1/64 symbol period.
