The Effects of Surface Energetics on the Cyclic Voltammetry of Metallocenes at Nonilluminated n ‐ InP Electrodes (1985)

Electron transfer processes at n‐type electrodes of moderate to low doping density were investigated by monitoring the cyclic voltammetric dark currents of a series of metallocenes in acetonitrile solutions. The formal reduction potentials of the metallocenes span the bandgap of , allowing a comparison of the cyclic voltammetric response as a function of the formal reduction potential and the energetic condition of the electrode surface. The energetic condition of the electrode surface during the cyclic voltammetry experiments was monitored by measurements of the capacitance of the space charge region. A simple chemical etching and electrochemical cycling procedure yielded reproducible surface energetics. The interface in the depletion condition responded ideally to changes in electrode potential, as evidenced by linear Mott‐Schottky plots, over a range of about 0.9V. It was possible to achieve an accumulation condition at negative potentials, but the interface could not be inverted at positive potentials. The interface is less susceptible to surface oxidation than is the interface. For each metallocene couple, the reversibility of cyclic voltammetric (CV) waves at was dependent on the doping density of the electrode and the proximity of the formal reduction potential to the conduction bandedge . Couples with located negative of displayed nearly reversible CV waves. Couples with located in the bandgap were reduced irreversibly at overvoltages of 400–500 mV. A couple with located slightly positive of yielded a partially reversible CV wave at moderate , but the wave became irreversible at low . Oxidation of couples with positive of −0.5V vs. for ferricenium/ferrocene was not observed.
Large-scale collective entity matching (2011)

There have been several recent advancements in Machine Learning community on the Entity Matching (EM) problem. However, their lack of scalability has prevented them from being applied in practical settings on large real-life datasets. Towards this end, we propose a principled framework to scale any generic EM algorithm. Our technique consists of running multiple instances of the EM algorithm on small neighborhoods of the data and passing messages across neighborhoods to construct a global solution. We prove formal properties of our framework and experimentally demonstrate the effectiveness of our approach in scaling EM algorithms.
The Deferasirox–AmBisome Therapy for Mucormycosis (DEFEAT Mucor) study: a randomized, double-blinded, placebo-controlled trial (2011)

Objectives: Host iron availability is fundamental to mucormycosis pathogenesis. The combination of liposomal amphotericin B (LAmB) and deferasirox iron chelation therapy synergistically improved survival in diabetic mice with mucormycosis. To determine the safety of combination deferasirox plus LAmB therapy for mucormycosis, a multicentred, placebo-controlled, double-blinded clinical trial was conducted.
The all-trans -retinal dimer series of lipofuscin pigments in retinal pigment epithelial cells in a recessive Stargardt disease model (2007)

The bis-retinoid pigments that accumulate in retinal pigment epithelial cells as lipofuscin are associated with inherited and age-related retinal disease. In addition to A2E and related cis isomers, we previously showed that condensation of two molecules of all-trans-retinal leads to the formation of a protonated Schiff base conjugate, all-trans-retinal dimer-phosphatidylethanolamine. Here we report the characterization of the related pigments, all-trans-retinal dimer-ethanolamine and unconjugated all-trans-retinal dimer, in human and mouse retinal pigment epithelium. In eyecups of Abcr(-/-) mice, a model of recessive Stargardt macular degeneration, all-trans-retinal dimer-phosphatidylethanolamine was increased relative to wild type and was more abundant than A2E. Total pigment of the all-trans-retinal dimer series (sum of all-trans-retinal dimer-phosphatidylethanolamine, all-trans-retinal dimer-ethanolamine, and all-trans-retinal dimer) increased with age in Abcr(-/-) mice and was modulated by amino acid variants in Rpe65. In in vitro assays, enzyme-mediated hydrolysis of all-trans-retinal dimer-phosphatidylethanolamine generated all-trans-retinal dimer-ethanolamine, and protonation/deprotonation of the Schiff base nitrogen of all-trans-retinal dimer-ethanolamine was pH-dependent. Unconjugated all-trans-retinal dimer was a more efficient generator of singlet oxygen than A2E, and the all-trans-retinal dimer series was more reactive with singlet oxygen than was A2E. By analyzing chromatographic properties and UV-visible spectra together with mass spectrometry, mono- and bis-oxygenated all-trans-retinal dimer photoproducts were detected in Abcr(-/-) mice. The latter findings are significant to an understanding of the adverse effects of retinal pigment epithelial cell lipofuscin.
480 km transmission of MDM 576-Gb/s 8QAM using a few-mode re-circulating loop (2013)

We demonstrate successful 3-mode-division-multiplexed × 192-Gb/s dual-polarization 8QAM (total 576 Gb/s) transmission over 480 km of few-mode fiber (FMF). This distance was obtained using an all few-mode re-circulating loop containing a 60 km FMF span.
Optimized broad-range real-time PCR-based method for bacterial screening of platelet concentrates (2020)

Bacterial contamination of blood components remains a major challenge in transfusion medicine, particularly, platelet concentrates (PCs) due to the storage conditions that support bacterial proliferation. In this study, we develop a rapid, sensitive and specific real-time PCR protocol for bacterial screening of PCs. An internally controlled real-time PCR-based method was optimized and validated with our proprietary 16S Universal PCR Master Mix (IBMP/Fiocruz), which targets a conserved region of the bacterial 16S rRNA gene. Nonspecific background DNA was completely eliminated by treating the PCR Master Mix with ethidium monoazide (EMA). A lower limit of detection was observed for 10 genome equivalents with an observed Ct value of 34±1.07 in calibration curve generated with 10-fold serial dilutions of E. coli DNA. The turnaround time for processing, including microbial DNA purification, was approximately 4 hours. The developed method showed a high sensitivity with no non-specific amplification and a lower time-to-detection than traditional microbiological methods, demonstrating it to be an efficient means of screening pre-transfusion PCs.
Proteomic analysis of the myoendothelial junction (2009)

Myoendothelial junctions (MEJ) are cellular projections through the internal elastic lamina originating from the vascular smooth muscle cell (VSMC) or endothelial cell (EC) layers that may serve as a distinct signaling domain, however the proteins that make up this domain are unknown. Using a vascular cell co‐culture model (VCCC) (Isakson et al., 2005), we demonstrate for the first time isolation of proteins specifically localized to the MEJ in vitro. Proteins from VSMC, EC and MEJ fractions were labeled separately with Cy5, Cy3, and Cy2 dyes respectively and subject to 2D‐DIGE analysis. Proteins within the MEJ fraction that displayed a minimum 2.5 increase in fluorescence intensity when compared to EC or VSMC fractions as determined by DeCyder software were chosen for mass spectrometry analysis and were compared to the NCBI protein database. Of the proteins identified at the MEJ, plasminogen activator inhibitor‐1 (PAI‐1) was shown to be one of the most abundant. Preferential expression of PAI‐1 at the MEJ was confirmed in vitro using immunoblotting and immunocytochemistry on the VCCC, as well as in vivo using transmission electron microscopy in multiple vascular beds. Based on this data we conclude that proteomic analysis of MEJ fractions in vitro provides valuable insight into possible protein interactions at the MEJ in vivo.

Collaborative Paper-Based Annotation of Lecture Slides. (2009)

In a study of notetaking in university courses, we found that the large majority of students prefer paper to computer-based media like Tablet PCs for taking notes and making annotations. Based on this finding, we developed CoScribe, a concept and system which supports students in making collaborative handwritten annotations on printed lecture slides. It includes mechanisms for the paper-based sharing and semantic tagging of annotations and slides. Moreover, we present a novel visualization of shared handwritten annotations providing an integrated access to annotations from all learners. The results of a user study indicate that CoScribe efficiently supports student annotation and can be easily integrated into current annotation practice.
Mechanism of laser-induced drug delivery in tumors (2000)

Penetration of anti-cancer drugs (especially macromolecular agents) from blood in tumor cells is limited due to the presence of physiological barriers: tumor capillary wall, slow diffusion in the interstitium, and cancer cell membrane. Interaction of exogenous nano- or microparticles with laser or ultrasonic radiation may enhance drug delivery in tumor cells due to laser- or ultrasound-induced cavitation. Our previous studies demonstrated enhanced delivery of model macromolecular anti-cancer drugs in tissues in vitro when laser or ultrasonic radiation is applied. In this paper, we studied laser-induced cavitation in suspension of strongly absorbing particles and laser-enhanced drug delivery in human colon tumors of nude mice in vivo. Cavitation kinetics and thresholds were measured for carbon and colored polystyrene particle suspensions. Histological examination of control and irradiated tumors with fluorescent microscopy demonstrated that Q-switched Nd:YAG laser irradiation enhances delivery of a model macromolecular drug (FITC-dextran) in tumor blood vessel and interstitium. Enhanced delivery of an anti-cancer drug (5-FU) that is currently used in clinics resulted in tumor necrosis and inhibited tumor growth. Results of our studies suggest that the drug delivery enhancement is due to cavitation produced by local heating of particles with pulsed laser radiation.
POSS Polystyrene Copolymers Reactivity and Control (2002)

Nano-sized inorganic clusters(POSS) can be incorporated into polystyrene copolymers from 1-99 wt%. These POSS clusters cause increases to the thermal transitions and mechanical properties of the polymers they are copolymerized into. The POSS effect on the properties of analogous polymers shows a dependency on the type of alkyl group on the POSS cluster. A degree of control over molecular weight can be made using standard kinetic polystyrene parameters. High molecular weight is necessary to maintain good mechanical properties. Reactivity ratios show that styrene monomer has no preference for reaction with itself or with a POSS-styrene. A POSS-styrene monomer, however, is more likely to react with styrene than with itself. Therefore, a copolymer sequence should be close to random.
1311 High wear resistance DLC film under high pressure contact (2012)

Diamond-like Carbon (DLC) is a hard film composed primarily of carbon and possessed amorphous structure. It is known to have superior tribological properties such as low friction, high wear resistance and anti-seizure. In addition, DLC film is now widely used in a various industrial application due to improvements in its adhesive property. This paper shows the DLC film with sputtering method has the durability under high pressure contact.
The gene pvaB encodes oxidized polyvinyl alcohol hydrolase of Pseudomonas sp. strain VM15C and forms an operon with the polyvinyl alcohol dehydrogenase gene pvaA The DDBJ accession number for the sequence reported in this paper is AB008494. (2000)

A 5.7 kbp SphI fragment containing the polyvinyl alcohol (PVA) dehydrogenase gene pvaA and its 1.9 kbp 5'-flanking region was cloned from the PVA-degrading bacterium Pseudomonas sp. VM15C. The pvaB gene, encoding oxidized PVA hydrolase, was found in the region upstream of pvaA. Sequence data and expression studies indicated that pvaA and B constitute an operon in the order pvaBA. The pvaB gene encoded a protein of 379 amino acid residues (40610 Da), and a lipoprotein signal sequence and the lipase consensus sequence, Gly-X-Ser-X-Gly, characteristic of the active-site serine region in serine hydrolases, were detected in the deduced amino acid sequence. The pvaB product with the pvaA product constituted an enzyme system for the cleavage of PVA molecules. The pvaA product introduced beta-diketone groups into the PVA molecule, and the pvaB product hydrolysed these beta-diketone groups in oxidized PVA. The pvaB product also hydrolysed 4,6-nonanedione at a low rate, but not acetylacetone or 5-nonanone. It was completely inhibited by PMSF and was concluded to be a serine hydrolase. There were no proteins showing high similarity to the pvaB product in the databases, but minor similarity to a number of serine hydrolases including polyhydroxyalkanoate depolymerases was apparent.
Periodicity in One-Dimensional Finite Linear Cellular Automata (1993)

We investigate the periodic structures of the trajectories in one-dimensional finite linear cellular automata with rule-90, whose time evolutions are described with matrices. The periodicity of the trajectories is found numerically and by use of eigenvalue equations. The period strongly depends on the number of sites. In some cases the null state becomes a limit point.

Indexing of multichannel images in the wavelet transform domain (2008)

In this work, we aim at optimizing the feature extraction step in the context of multichannel image indexing in the compressed domain, especially the wavelet based domain. To extract the salient signatures, the distribution of the multicomponent wavelet coefficients is modelized according to two different approaches. The first one is a univariate approach: the spectral channels are considered as independent and the signatures are separately computed from each component. The second approach is a multivariate one. It aims at finding an appropriate joint multivariate model whose parameters are the image signatures. The objective of this work is to compare the retrieval performances of the two following multivariate models: the Multivariate Generalized Gaussian Distribution (MGGD) model and a copula-based model. To this respect, an appropriate goodness-of-fit test is used in order to compare the adjustment of the the two models with the empirical histogram of the multivariate wavelet coefficients. Secondly, we compare the performances of retrieval in terms of precision, recall and complexity given by the multivariate approach based on the two models. Comparison between the univariate and the multivariate approach is also performed on natural multichannel images.
A randomized trial of coenzyme Q10 in mitochondrial disorders (2010)

Case reports and open-label studies suggest that coenzyme Q(10) (CoQ(10)) treatment may have beneficial effects in mitochondrial disease patients; however, controlled trials are warranted to clinically prove its effectiveness. Thirty patients with mitochondrial cytopathy received 1200 mg/day CoQ(10) for 60 days in a randomized, double-blind, cross-over trial. Blood lactate, urinary markers of oxidative stress, body composition, activities of daily living, quality of life, forearm handgrip strength and oxygen desaturation, cycle exercise cardiorespiratory variables, and brain metabolites were measured. CoQ(10) treatment attenuated the rise in lactate after cycle ergometry, increased (∽1.93 ml) VO(2)/kg lean mass after 5 minutes of cycling (P < 0.005), and decreased gray matter choline-containing compounds (P < 0.05). Sixty days of moderate- to high-dose CoQ(10) treatment had minor effects on cycle exercise aerobic capacity and post-exercise lactate but did not affect other clinically relevant variables such as strength or resting lactate.
Following Gaze Across Views (2016)

Following the gaze of people inside videos is an important signal for understanding people and their actions. In this paper, we present an approach for following gaze across views by predicting where a particular person is looking throughout a scene. We collect VideoGaze, a new dataset which we use as a benchmark to both train and evaluate models. Given one view with a person in it and a second view of the scene, our model estimates a density for gaze location in the second view. A key aspect of our approach is an end-to-end model that solves the following sub-problems: saliency, gaze pose, and geometric relationships between views. Although our model is supervised only with gaze, we show that the model learns to solve these subproblems automatically without supervision. Experiments suggest that our approach follows gaze better than standard baselines and produces plausible results for everyday situations.

Both problems are known to be NP -hard and were the subject of the 2019 Computational Geometry Challenge, which presented the quest of finding good solutions to more than 200 instances, ranging from n = 10 all the way to n = 1, 000, 000.
Clock distribution networks for 3-D ictegrated Circuits (2008)

Three-dimensional (3D) integration is an important technology that addresses fundamental limitations of on-chip interconnects. Several design issues related to 3D circuits, such as multi-plane synchronization, however, need to be addressed. A comparison of three 3D clock distribution network topologies is presented in this paper. Experimental results of a 3D test circuit manufactured by the MIT Lincoln Laboratories are also described. Successful operation of the 3D test circuit at 1.4 GHz is demonstrated. Clock skew and power dissipation measurements for the different clock topologies are also provided.

A 39 GHz MU-MIMO using 256 Element Hybrid AAS with Coherent Beam-Forming for 5G and Beyond IAB Applications (2022)

This paper describes the design and implementation of a 39GHz 256 element hybrid active phased array antenna system (AAS) which has the 16 individual digital transceivers, and its over-the-air (OTA) multi-user multiple-input multiple-output (MU-MIMO) verification. We have demonstrated the single carrier 1 GHz bandwidth 128 QAM transmission assuming the mobile-back-haul (MBH) link, and the OFDM 100 MHz bandwidth four users MU-MIMO using the zero-forcing (ZF) orthogonal multi-beams based on the channel reciprocity assuming the access links by using an AAS. The EIRP of 43 dBm in terms of 200 m link distance and the data rate of 5.5 Gbps with the 128 QAM in the single carrier operation, and the estimated total throughput of 1.59 Gbps according to 3GPP TS38.214 MCS table 2 in OFDM four (4) MU-MIMO have been achieved respectively. As per author's knowledge, this is a first demonstration assuming IAB applications using 39 GHz band.

OpticalIy Pumped Chemiluminescence of Indole‐3‐Acetic Acid (1996)

ABSTRACT Optically pumped chemiluminescence of indole‐3‐acetic acid (IAA) was observed and studied. Rose Bengal (RB) was used as a photosensitizer. Long‐lived chemiluminescence (CL) appeared after irradiation of the IAA/RB reaction mixture by monochromatic light at 550 nm (the maximum of RB absorption) or by visible light. The CL spectrum had a maximum at 480 nm. The kinetics of the CL decay were single exponential. Single‐exponential kinetics were characterized by two experimentally measured values: initial CL intensity and exponential lifetime of the CL decay. We studied the influence of five parameters: (1) the rate of irradiation fluence, (2) the time of irradiation, (3) RIB concentration, (4) IAA concentration and (5) buffer pH on the initial CL intensity and the CL lifetime. Initial CL intensity was proportional to the rate of irradiation fluence and the concentration of RB. Saturation was observed in dependencies of initial CL intensity on the time of irradiation, the concentration of IAA and the buffer pH. The lifetime of the CL decay decreased with increasing pH and did not depend on the other four parameters. The mechanism explaining the experimental results was suggested and detailed kinetic analysis was performed to prove the proposed mechanism. Quantum yield of the CL and five rate constants that are involved in the mechanism were determined.

Nonlinear Model Predictive Control and Collision-Cone-Based Missile Guidance Algorithm (2021)

In this paper, a hybrid missile guidance algorithm is proposed for planar engagement scenarios. The method combines nonlinear model predictive control (NMPC) with a collision cone approach, and enables the guidance algorithm to achieve interception, while ensuring that the impact angle lies in a predefined range. The guidance scheme comprises two components: 1) point-mass-based NMPC and 2) collision-cone-based NMPC. The point-mass-based NMPC is employed when the distance between the missile and the target is large, and when this distance falls below a threshold, the algorithm switches to a collision-cone-based NMPC. Connections between the impact angle and the collision cone are theoretically established, and these are used in the collision-cone-based NMPC. The NMPC problems are formulated as quadratic programs that include appropriate constraints on the states and inputs, while not requiring target acceleration information. These quadratic programs are shown to be strictly convex. Detailed simulations are performed to demonstrate the effectiveness of the proposed approach.
Microwave transmission through a two-dimensional, isotropic, left-handed metamaterial (2001)

We present experimental data, numerical simulations, and analytical transfer-matrix calculations for a two-dimensionally isotropic, left-handed metamaterial (LHM) at X-band microwave frequencies. A LHM is one that has a frequency band with simultaneously negative εeff(ω) and μeff(ω), thereby having real values of index of refraction and wave vectors, and exhibiting extended wave propagation over that band. Our physical demonstration of a two-dimensional isotropic LHM will now permit experiments to verify some of the explicit predictions of reversed electromagnetic-wave properties including negative index of refraction as analyzed by Veselago [Usp. Fiz. Nauk 92, 517 (1964), Sov. Phys. Usp. 10, 509 (1968)].
