An architecture for wireless simulation in NS-2 applied to impulse-radio ultra-wide band networks (2007)

We present an architecture for implementing a wireless physical layer in a packet-based network simulator. We integrate this architecture in the popular ns-2 network simulator and use it to implement an impulse-radio ultra-wide and band (IR-UWB) physical layer. Contrary to the current wireless physical layer implementation of ns-2, in our case a packet is fully received by our physical layer before being delivered to the MAC layer. A packet detection and timing acquisition model has been implemented. Furthermore, for each packet, a packet error rate (PER) can be computed as a function of the received power, interference from concurrent transmissions, and thermal noise. This architecture is quite generic and allows for the simulation of any physical layer where an accurate model of interference is of high importance, e.g., IR-UWB or CDMA. Our implementation for IR-UWB takes into account transmissions with different time-hopping sequences (THS). The underlying modulation is binary phase shift keying (BPSK), followed by a variable-rate channel code. Our implementation is the first available that allows for the simulation of IR-UWB networks. It is modular and can thus be easily modified and extended.
Pilot Prospective Evaluation of 99mTc-MDP Scintigraphy, 18F NaF PET/CT, 18F FDG PET/CT and Whole-Body MRI for Detection of Skeletal Metastases (2013)

Our pilot phase prospective trial demonstrated superior image quality and evaluation of skeletal disease extent with 18F NaF PET/CT compared to 99mTc-MDP scintigraphy and 18F FDG PET/CT, as well as the feasibility of multisequence WBMRI. In addition, 18F FDG PET/CT provided valuable soft-tissue information that can change disease management. Further evaluation of these findings using the recently introduced PET/MRI scanners is warranted.
The Multidrug Efflux Regulator TtgV Recognizes a Wide Range of Structurally Different Effectors in Solution and Complexed with Target DNA (2005)

TtgV modulates the expression of the ttgGHI operon, which encodes an efflux pump that extrudes a wide variety of chemicals including mono- and binuclear aromatic hydrocarbons, aliphatic alcohols, and antibiotics of dissimilar chemical structure. Using a 'lacZ fusion to the ttgG promoter, we show that the most efficient in vivo inducers were 1-naphthol, 2,3-dihydroxynaphthalene, 4-nitrotoluene, benzonitrile, and indole. The thermodynamic parameters for the binding of different effector molecules to purified TtgV were determined by isothermal titration calorimetry. For the majority of effectors, the interaction was enthalpy-driven and counterbalance by unfavorable entropy changes. The TtgV-effector dissociation constants were found to vary between 2 and 890 mum. There was a relationship between TtgV affinity for the different effectors and their potential to induce gene expression in vivo, indicating that the effector binding constant is a major determinant for efficient efflux pump gene expression. Equilibrium dialysis and isothermal titration calorimetry studies indicated that a TtgV dimer binds one effector molecule. No evidence for the simultaneous binding of multiple effectors to TtgV was obtained. The binding of TtgV to a 63-bp DNA fragment containing its cognate operator was tight and entropy-driven (K(D) = 2.4 +/- 0.35 nm, DeltaH = 5.5 +/- 0.04 kcal/mol). The TtgV-DNA complex was shown to bind 1-napthol with an affinity comparable with the free soluble TtgV protein, K(D) = 4.8 +/- 0.19 and 3.0 +/- 0.15 mum, respectively. The biological relevance of this finding is discussed.
CTL induction using synthetic peptides delivered in emulsions— critical role of the formulation procedure (1997)

Emulsions have been used with variable degrees of success to deliver antigen to stimulate immune responses. We have investigated three different ways of incorporating peptide antigen into soybean emulsions to induce CTL responses in mice. Two of these emulsions (oil-in-water, o/w, and water-in-oil-in-water, w/o/w) had peptide incorporated at the formulation stage, while the third had peptide added to a pre-formed o/w emulsion. High levels of CTL activity were induced when peptide was dispersed into the o/w or w/o/w emulsions, in contrast to addition of peptide to the pre-formed o/w emulsion, which did not stimulate a CTL response. Induction of CTL activity was independent of emulsion globule size but was correlated with a negative zeta potential and dispersion of peptide in the oil phase. The ability of peptide in soybean oil emulsion to induce CTL is critically dependent on dispersion of peptide at the time of emulsion formation.

Diagnostic performance of a point-of-care saliva urea nitrogen dipstick to screen for kidney disease in low-resource settings where serum creatinine is unavailable (2020)

Enriching a Thai Lexical Database with Selectional Preferences (2004)

A statistical corpus-based approach for acquiring selectional preferences of verbs is proposed. By parsing through text corpora, we obtain examples of context nouns that are considered to be the selectional preferences of a given verb. The approach is to generalize initial noun classes to the most appropriate levels on a semantic hierarchy. We present an iterative algorithm for generalization by combining an agglomerative merging and a model selection technique called the Bayesian Information Criterion (BIC). In our experiments, we consider the Web as the large corpora. We also propose approaches for extracting examples from the Web. Preliminarily experimental results are given to show the feasibility and effectiveness of our approach. 1.
Cross-modal correspondence between vibrations and colors (2017)

Participants matched a color to a vibrotactile stimulus of 1 s duration on the palm of the hand. Stimuli were combinations of one of six frequencies (10-200 Hz) and four amplitudes (10-40 dB SL). Color choices were converted to lightness, chroma, and hue angle values defined in the CIELAB color space. Results showed that the color chroma increases with the increase in vibratory amplitude, with no effect of vibration frequency. Lightness was not significantly modulated by the vibratory variables. Histograms of color hue showed three main peaks (violet, red and green) in participants' responses. The pattern was for low-frequency vibrations (1035 Hz) to evoke the violet color hue at low amplitudes and the red color hue at high amplitudes, whereas high-frequency vibrations (60-200 Hz) evoked the green color hue with some trace of the red color hue at high amplitudes. The results are discussed for designing colorful experiences using vibrotactile feedback.
Formation of X-waves at fundamental and harmonics by infrared femtosecond pulse filamentation in air (2008)

We experimentally observe the formation of X-waves at fundamental, third harmonic, and fifth harmonic wavelengths by infrared (central wavelength at ∼1500 nm) femtosecond laser pulse filamentation in air. By fitting the angularly resolved spectra of the fundamental and harmonic waves using X-wave relations, we confirm that all the X-waves have nearly the same group velocity, indicating that they are locked in space and time during their propagation in filament.
Measurement of Q degradation due to PMD using importance sampling (2003)

We use multiple importance-sampling (IS) to measure the Q degradation due to PMD emulated by three programmable DGD elements with uniform polarization-coupling between sections. The measured Q-penalty probability distribution extends to 1017 samples are required to examine such low-probability events.
The 3p21.3 Tumor Suppressor NPRL2 Plays an Important Role in Cisplatin-Induced Resistance in Human Non–Small-Cell Lung Cancer Cells (2006)

NPRL2 is one of the novel candidate tumor suppressor genes identified in the human chromosome 3p21.3 region. The NPRL2 has shown potent tumor suppression activity in vitro and in vivo and has been suggested to be involved in DNA mismatch repair, cell cycle checkpoint signaling, and regulation of the apoptotic pathway. In this study, we analyzed the endogenous expression of the NPRL2 protein and the cellular response to cisplatin in 40 non-small-cell lung cancer cell lines and found that expression of NPRL2 was significantly and reciprocally correlated to cisplatin sensitivity, with a Spearman correlation coefficient of -0.677 (P < 0.00001). Exogenously introduced expression of NPRL2 by N-[1-(2,3-dioleoyloxyl)propyl]-NNN-trimethylammoniummethyl sulfate:cholesterol nanoparticle-mediated gene transfer significantly resensitized the response to cisplatin, yielding a 40% greater inhibition of tumor cell viability and resulting in a 2- to 3-fold increase in induction of apoptosis by activation of multiple caspases in NPRL2-transfected cells compared with untransfected cells at an equal dose of cisplatin. Furthermore, a systemic treatment with a combination of NPRL2 nanoparticles and cisplatin in a human H322 lung cancer orthotopic mouse model significantly enhanced the therapeutic efficacy of cisplatin and overcame cisplatin-induced resistance (P < 0.005). These findings implicate the potential of NPRL2 as a biomarker for predicting cisplatin response in lung cancer patients and as a molecular therapeutic agent for enhancing response and resensitizing nonresponders to cisplatin treatment.
Adhesion of microwave‐plasma‐treated fluoropolymers to thermoset vinylester (2005)

Abstract Poly(tetrafluoroethylene) and a fluoroethylene copolymer were surface treated with a 2.45‐GHz microwave plasma to enhance their adhesion to a vinylester thermoset. The plasmas were generated with an inert gas (Ar) and with reactive gases (H 2 , O 2 , and N 2 ). The lap‐joint shear stress was measured on fluoropolymer samples glued with the vinylester. In general, the stress at failure increased with increasing plasma‐energy dose. The H 2 plasma yielded the best adhesion, and X‐ray photoelectron spectroscopy revealed that it yielded the highest degree of defluorination of the fluoropolymer surface. The defluorination efficiency declined in the order H 2 , Ar, O 2 , and N 2 . Contact angle measurements and scanning electron microscopy revealed that the surface roughness of the fluoropolymer depended on the rate of achieving the target energy dose. High power led to a smoother surface, probably because of a greater increase in temperature and partial melting. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 98: 838–842, 2005
Light-intensity dependence in the photochromism of dibenzo[2.2](4,4′)-azobenzenophane (1991)

Reduction of 4′,4″-dinitro-o-terphenyl under conditions of high dilution, produces a mixture of macrocyclic poly(azobenzene) compounds. From the mixture, three kinds of macrocycle, namely, dimer 2{dibenzo[2.2](4,4′)azobenzenophane}, trimer 3 and tetramer 4 have been isolated pure. In toluene, absorption peaks due to the π→π* transition for the macrocycles undergo dramatic hypsochromic shifts as the ring size of the macrocycles decreases from the trimer 3 to the dimer 2; this is an indication that benzene rings at both ends of the dimer 2 are fixed perpendicularly to two azobenzene planes in the macrocycle. The photostationary state of the dimer 2 in toluene at λ= 366 nm contained the EZ isomer which undergoes thermal isomerization to the more stable EE isomer at the first-order rate of 0.768 s–1. The reaction of 2 is much faster than that of the dimer 5, which was described in our last paper. Due to the fast thermal EZ to EE isomerization, the efficiency of the photoisomerization from the EE isomer to the ZZ isomer is light-intensity dependent. This dependence is observed at higher light intensities for the dimer 2 than for the dimer 5.
MOSFET optimization toward power efficient circuit design (2018)

The report focuses on an optimization scheme of advanced MOSFETs for designing power efficient circuits. For the purpose the physics-based compact model HiSIM2 is applied so that the relationship between device and circuit characteristics can be investigated properly. It is demonstrated that the short-channel effect, which is usually measured by the threshold-voltage shift compared to the long-channel MOSFET, provides the consistent measure as the short-channel effect on device performance degradation. However, the circuitry performances degradation such as the power loss cannot be predicted sufficiently by the short channel effect alone. It is demonstrated that the power efficient circuit design can be achieved by minimizing the additional leakage current caused by the short-channel contribution.
Hippodrome: running circles around storage administration (2002)

Enterprise-scale computer storage systems are extremely difficult to manage due to their size and complexity. It is difficult to generate a good storage system design for a given workload and to correctly implement the selected design. Traditionally, initial system configuration is performed by administrators who are guided by rules of thumb. Unfortunately, this process involves trial and error, and as a result is tedious and error-prone. In this paper, we introduce Hippodrome, an approach to automating initial system configuration. Hippodrome is an iterative loop that analyzes an existing system to determine its requirements, creates a new storage system design to better meet these requirements, and migrates the existing system to the new design. In this paper, we show how Hippodrome automates initial system configuration. 1
On the Drivability of DC Brushless Motors with Faulty Hall Sensors during Braking Maneuvers (2020)

Brushless DC motors are now a standard for many engineering applications. To work properly, they need to be controlled based on rotor angle position, usually retrieved by a set of three Hall sensors. Their breakdown can be detrimental, not only in all the cases in which maintenance stops result in economic losses but especially for safety critical applications, where functionality must be always ensured. This paper investigates the drivability of such motors with a reduced number of Hall sensors for vehicles equipped with electronic brakes. A drivability bound is mathematically derived for a three-phase Brushless DC motor, whose phase voltages and currents are not known. An angle estimation algorithm, merging electrical measurements and available Hall sensors, is proposed. Experimental results are finally provided on bicycles braking maneuvers to further support the proposed study.
The effect of continuous intravenous norepinephrine infusion on systemic hemodynamics in a telemetrically-monitored mouse model of sepsis (2022)

Sepsis, a life-threatening organ dysfunction, results from dysregulated host responses to infection and still has a high incidence and mortality. Although administration of vasopressors to treat septic shock is standard of care, the benefits are not well established. We evaluated the effect of continuous intravenous norepinephrine infusion in a septic cecal ligation and puncture (CLP) mouse model, evaluating systemic hemodynamics and body temperature post-hoc. CLP surgery significantly decreased mean arterial blood pressure (MAP), heart rate, and body temperature within six hours. Continuous norepinephrine infusion (NE+, n = 12) started at the time of CLP surgery significantly increased MAP at 24 and 30 hours and heart rate at 6, 18, 24, and 30 hours after CLP vs CLP alone (NE-, n = 12). However, addition of norepinephrine did not improve survival rate (NE+ n = 34, NE- n = 31). Early (6 hours or earlier, when the animal became visibly sick) MAP did not predict 7-day mortality. However, heart rates at 3 and at 6 hours after CLP/norepinephrine (NE+) were highly predictive of mortality, as also been found in one clinical study. We conclude that limited hemodynamic support can be provided in a mouse sepsis model. We propose that heart rate can be used to stratify severity of illness in rodent preclinical studies of sepsis therapeutics.
Atrial Pacing Lead Location Alters the Effects of Atrioventricular Delay on Atrial and Ventricular Hemodynamics (2002)

The combined role of atrial pacing lead location and AV timing on cardiovascular performance has not been defined. This study tested the hypothesis that atrial pacing lead location can change the dependence of LA and LV hemodynamics on AV timing in vivo. Dogs anesthetized with isoflurane (n = 8) were instrumented for measurement of hemodynamics including LA pressure, LA volume, and pulmonary venous bloodflow. Data were recorded during normal sinus rhythm, and atrial overdrive pacing from the right atrial appendage (RAA), proximal coronary sinus (CS), and LA lateral wall (LAW). The AV node was then ablated and measurements repeated during synchronous ventricular pacing and during dual chamber pacing from each atrial lead location at various AV delays (20, 60, 120, 180, 240, and 350 ms). Hemodynamics during intrinsic sinus rhythm and overdrive atrial pacing from different sites were similar. In contrast, ventricular or dual chamber pacing caused significant (P < 0.05) changes in cardiac output with different AV timing during RAA (3.5 +/- 0.2 vs 2.9 +/- 0.2 L/min at 120 and 350 ms, respectively) and LAW pacing but not CS pacing. A significant interaction between atrial lead location and AV delay was observed for changes in stroke volume, pulmonary venous blood transport, LA volume, and LV preload. The results indicate that the atrial contribution to cardiac output depends on AV timing and atrial lead location in isoflurane-anesthetized dogs with AV nodal conduction block.
Synthesis of poly(butylene succinate) using metal catalysts (2014)

The synthesis of poly(butylene succinate) (PBS) was studied to evaluate the effect of some key process parameters on the final material properties. PBS was produced through direct esterification in open and closed systems, in the presence and absence of nitrogen, using two different monomers (succinic acid and anhydride). PBS was also produced through transesterification at different temperatures and using different metal catalysts. The products were characterized by gel permeation chromatography, nuclear magnetic resonance, Fourier transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and polymer melt rheology. Based on the obtained results, it can be said that the best set of final properties can be obtained when PBS is produced with succinic acid in closed systems and under nitrogen atmosphere through transesterification and in presence of titanium‐based catalysts. Besides, the catalyst concentration was found to exert the largest effect on the final average molecular weight ( M w ) and viscosity of the resin, while the temperature increase can lead to significant polymer degradation.

Continuous surface-relief microoptical elements and their replication in polymer and other materials (2003)

This paper describes the enabling technologies developed at INO to generate continuous surface-relief profile diffractive and refractive optical elements in photoresist. Grey-scale mask photolithography based on high-energy beam sensitive glass and laser direct writing have been used to fabricate aspherical refractive and diffractive microlenses respectively. Properties of refractive microlenses are compared to those fabricated by the standard reflow technique. The replication of such elements by injection molding and UV-embossing in acrylic and custom hybrid sol-gel glasses respectively is described. Fidelity of replication in the various processing steps is given. Optical performance of aspherical microlenses with f-numbers between 0.69 and 7 as well as thermo-mechanical properties of organic/inorganic materials are given.
Optical Characterization of High-Order 1-D Silicon Photonic Crystals (2009)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> In this paper, we present numerical and experimental results on the spectral reflectivity of hybrid, high-order (up to 22nd) 1-D silicon photonic crystals (PCs) in the near-infrared region (wavelength range 1– <formula formulatype="inline"><tex Notation="TeX">$1.7\ \mu $</tex></formula>m). Mechanically robust, vertical 1-D PCs with high aspect ratio and spatial period of <formula formulatype="inline"><tex Notation="TeX">$8\ \mu $</tex></formula>m were fabricated by electrochemical micromachining of silicon, and tested in reflection with an improved optical setup, incorporating standard telecommunication single-mode optical fibers and a lensed fiber pigtail.

Experimental data were found in very good agreement with theoretical calculations, performed by using the characteristic matrix method, keeping into account an in-plane porosity variation for 1-D PCs, due to surface roughness of silicon walls, and the limited resolution bandwidth of the spectrum analyzer.
