Via sidewall insulation for through cell via contacts (2017)

Over the past few years, through cell via contacts (TCVC) architecture has been the object of a growing interest to replace standard front side and backside contact on concentrated photovoltaic (CPV) cells. The technology is based on transferring the front side contact to the backside using insulated and metallized vias. This architecture could reduce shading and series resistance, thus increasing device efficiency. However, the processes involved in TCVC fabrication increases the risk of creating short-circuit, reducing significantly the efficiency of the solar cell. Therefore, the electrical insulation must be defect free. In this paper, an insulation validation protocol is proposed in order to thoroughly study the insulation quality. This process has been used to compare two insulation deposition techniques candidates: plasma-enhanced chemical vapor deposition (PECVD) and plasma-enhanced atomic layer deposition (PEALD). Results show that the insulation validation protocol presents several strengths such as revealing defects otherwise unobservable even with scanning electron microscopy. PECVD insulation presents several insulation defects whereas PEALD presents almost no defects making it suited for via insulation.
Long-Circulating Polymeric Nanovectors for Tumor-Selective Gene Delivery (2005)

Significant advances in the understanding of the genetic abnormalities that lead to the development, progression, and metastasis of neoplastic diseases has raised the promise of gene therapy as an approach to medical intervention. Most of the clinical protocols that have been approved in the United States for gene therapy have used the viral vectors because of the high efficiency of gene transfer. Conventional means of gene delivery using viral vectors, however, has undesirable side effects such as insertion of mutational viral gene into the host genome and development of replication competent viruses. Among non-viral gene delivery methods, polymeric nanoparticles are increasingly becoming popular as vectors of choice. The major limitation of these nanoparticles is poor transfection efficiency at the target site after systemic administration due to uptake by the cells of reticuloendothelial system (RES). In order to reduce the uptake by the cells of the RES and improve blood circulation time, these nanoparticles are coated with hydrophilic polymers such as poly(ethylene glycol) (PEG). This article reviews the use of such hydrophilic polymers employed for improving the circulation time of the nanocarriers. The mechanism of polymer coating and factors affecting the circulation time of these nanocarriers will be discussed. In addition to the long circulating property, modifications to improve the target specificity of the particles and the limitations of steric protection will be analyzed.

Blood Rheology and Platelet Function in Untreated Early-Stage Essential Hypertensives Complicated with Metabolic Syndrome (2012)

We examined whether hemorheology and platelet function are affected in essential hypertensives (EHTs) of the World Health Organization stage I when complicated with metabolic syndrome (Mets). In 156 untreated EHTs, blood viscosity and platelet surface markers were determined. Blood viscosity was significantly elevated in 54 subjects with Mets compared with 102 subjects without Mets. Hematocrit and plasma viscosity increased in the group with Mets, although red blood cell rigidity index "k" did not differ between groups. As a whole group, blood viscosity correlated positively with hematocrit and plasma viscosity. Additionally, plasma viscosity correlated positively with plasma leptin, triglyceride, homeostasis model assessment index, C-reactive protein, and plasma fibrinogen, but negatively with high-density lipoprotein cholesterol. In contrast, no differences were seen in platelet surface markers between groups. In conclusion, EHTs of the early stage complicated with Mets are characterized by increased blood viscosity due to hemoconcentration and increased plasma viscosity.
Mass Spectrometric Determination of the Cleavage Sites inEscherichia coli Dihydroorotase Induced by a Cysteine-specific Reagent (1997)

Escherichia coli dihydroorotase contains six cysteines/subunit, which are potential ligands of structural and catalytic zinc metals at protein sites of the enzyme. Specific thiol reagents modify, in nondenaturing conditions only, two of these cysteines; these two residues are thought to be ligands of structural zinc. We report here on the localization of these two cysteines on the polypeptide chain through their cyanylation by 2-nitro-5-thiocyanobenzoic acid (NTCB) and the analysis by mass spectrometry of the protein adducts. This is the first study of E. coli dihydroorotase by mass spectrometry, allowing the accurate determination of the subunit molecular weight (38,695). Treatment of dihydroorotase by NTCB induced a cleavage N-terminal to the cyanylated cysteines. The resulting fragments visualized on electrophoresis gel have been N-terminal sequenced, and their masses were determined by electrospray-ionizing mass spectrometry. This allowed the identification of cysteines 221 and 265 as the two residues cyanylated by the reagent NTCB. Results from gel filtration of dihydroorotase cyanylated on the two cysteines indicate that these residues are involved in subunit interactions leading to the active dimer. Consistent with literature data, we assume that cysteine 221 and cysteine 265, along with the neighboring cysteines 263 and 268 arranged in cluster, are potential ligands of structural zinc of E. coli dihydroorotase.

Water Vapor Permeability of Edible Bilayer Films (1984)

ABSTRACT Edible films composed of a water soluble, carbohydrate layer (hydroxypropyl methylcellulose) and various kinds of lipid layers were tested for resistance to water vapor permeability. Films were tested at 25°C and a relative humidity differential of 85%. Films containing solid lipids, such as beeswax, paraffin, hydrogenated palm oil or stearic acid yielded permeabilities of 0.2 g · mil · day −1 · mmHg −1 or less which is a smaller value than that for low density polyethylene.
An improved approach to open set text-independent speaker identification (OSTI-SI) (2017)

This paper focuses on open set text independent speaker identification which is one of the most challenging subclass of Speaker recognition. The initial stage is similar to closed set speaker identification, where the distortion for each test voice against all train voices are determined. The distortions after normalization is set as decision criteria which eases the process of thresholding. The threshold variation which is mostly independent of dataset but dependent on the size of train data set and its values are quite similar for three datasets. The identification rate with balanced False Acceptance Rate(FAR) and False Rejection Rate(FRR) is 73–86%.
High-resolution sensorless position estimation using delta-sigma-modulated current measurement (2011)

Sensorless speed and position control of surface mounted permanent magnet synchronous machines (SMPMSMs) is of special interest in industrial automation due to their high efficiency and simple design. However these types of machines have no geometrical saliencies and the exploitable magnetic anisotropies result solely from magnetic saturation and are therefore very small. The measurable position dependent current components resulting from injected high frequency voltages are hence very small and a high resolution current measurement is needed. This paper proposes a novel technique for injecting an alternating carrier voltage. The high frequency current components are measured using delta-sigma-modulators. Suitable design of the low-pass filters and appropriate processing of the measured current values allows to achieve a very high signal to noise ratio. The proposed analytical approach to separate the high frequency current components from the fundamental wave current portion avoids any interference between the current controller and the high frequency voltage injection. Therefore the extracted position information will not be affected by the fundamental current components even during transient conditions. The separation scheme is free of any motor parameters and can cope with significant nonlinear inductances.

[Idiopathic congenital club foot: results of functional treatment (269 feet)]. (1990)

The manipulative treatment consisted of manipulations, muscular stimulations and fixation of the foot on a sole with non elastic strapping. This "functional" method used since the neonatal period was studied in 183 infants (269 clubfeet) with an average follow-up of 6 years and 2 months. A surgical release completed the correction in 139 feet. The initial examination permitted to distinguish 3 different grades of clubfeet, according to the clinical stiffness. The physiotherapist who treated the patients were separated in "specialized" and "unspecialized". During the evolution, 5 different categories were defined according to the clinical and radiological aspects. The criteria adopted for evaluating the results were scored with a screen of 100 points. The results obtained from 157 feet with a minimal follow-up of 4 years, were excellent and good in 86.6 per cent cases, fair in 10.2 per cent and poor in 3.2 per cent. The global results of the "functional" method, taking the insufficient follow-up into account, are for the whole series: success in 38.7 per cent, intermediary results in 15.6 per cent and failure in 45.7 per cent. The main factors which have a pejorative influence on the results are the irreducibility (according to the initial classification), the "unspecialized" physiotherapists, the socio-familial problems.
Radioreceptor Assays for Sensitive Detection and Quantitation of Saxitoxin and Its Analogues from Strains of the Freshwater Cyanobacterium, <i>Anabaena circinalis</i> (2001)

Toxic freshwater cyanobacteria can contaminate water supplies and adversely effect humans, agricultural livestock, and wildlife. Toxicity is strain-specific so morphological observations alone cannot predict the hazard level. Two microtiter plate based bioassays have emerged for measuring saxitoxin (STX) and its derivatives, commonly found in the freshwater cyanobacteria Anabaena and Aphanizomenon. They use radioactively labeled STX binding by sodium channels, STX's pharmacological target, or an unrelated protein, saxiphilin. These bioassays were challenged with extracts of toxic and nontoxic strains of Anabaena circinalis, and the results were compared with HPLC analysis. Both radioreceptor assays had detection limits of 2 microg STX equivalents (STXeq)/L, which is belowthe concentration proposed for a health alert, namely 3 microg STXeq/L. In all cases, statistically significant correlations existed between all toxicity measurements of the same extracts with the methods used herein. Sodium channel and saxiphilin assays however predicted less toxicity relative to HPLC analysis. The only exception to this was the equivalency observed between saxiphilin measurement and HPLC quantitation corrected for mammalian toxicity. Saxiphilin assay predicted toxicity in one strain was 3 orders of magnitude more than by sodium channel assay, and no STX was detected by HPLC. Lack of acetylcholinesterase inhibition showed this bioactivity was not anatoxin-a(S), a toxin also produced by this A. circinalis with some resemblance to the region of STX bound by saxiphilin. Presence of anatoxin-a(S) was predicted for another strain by this same acetylcholinesterase assay that, if confirmed by chemical analysis, would be the first report of anatoxin-a(S) in an Australian cyanobacterium.
PROMOTION OF ROOT INITIATION BY GIBBERELLIC ACID IN LEAF DISCS OF TOMATO (<i>LYCOPERSICON ESCULENTUM</i>) CULTURED <i>IN VITRO</i> (1977)

SUMMARY Gibberellic acid (GA 3 ) stimulated the rooting of tomato leaf discs cultured on a defined nutrient medium in continuous darkness. In the presence of 2 × 10 −4 M tryptamine, GA 3 significantly enhanced root initiation over the concentration range of 1 × 10 −8 M to 1 × 10 −4 M. GA 3 could be replaced by GA 4/7 but not by kinetin. Indole‐3‐lactic acid was a highly active indole derivative in the induction of rooting in the tomato leaf discs. This effect was significantly enhanced by GA 3 . Possible reasons for this observation are discussed.
Mode mixing and polarization scrambling microparticles in polymeric resin filled optical couplers (1993)

The fiber-to-fiber uniformity, optical loss, and size of polymeric multimode combiners and splitters was enhanced by the addition of mode mixing microspheres when low numerical aperture (NA) sources were used. Mixing rod type resin filled polymeric optical couplers could be significantly shortened when used with small beam divergence angle lasers and other small NA sources. The small NA beam divergence angle causes the energy to remain in low-order modes for desired mixing lengths, causing fiber-to-fiber nonuniformity. A solution to this problem a mode mixing refractive microsphere technology, is presented. Results demonstrate that the use of the microspheres improved the performance of both optical splitters and combiners. Silica microparticles were suspended in the polymer mixing regions of the couplers. The shortened mixing lengths accomplished with the microparticles also makes it possible to use polymeric couplers with longer wavelengths of light where polymers are not as transparent.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Run-time disambiguation: coping with statically unpredictable dependencies (1989)

A technique called run-time disambiguation (RTD) is presented for antialiasing of indirect memory references that cannot normally be disambiguated at compile time. The technique relies on assumptions about the run-time behavior of a program to allow static transformations of the code, in an effort to extract parallelism. The importance of the technique lies in its ability to supplement (and even partially replace) more expensive fully static dependency analysis. RTD works even in situations where the fully static approach is completely ineffective. Evidence of the importance of memory disambiguation in general, and RTD in particular, for parallelizing compilers, is presented. The implementation and effectiveness of the technique in the context of the Bulldog compiler is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Structure-receptor binding relationships of sarafotoxin and endothelin in porcine cardiovascular tissues. (1990)

The specific binding of 125I-sarafotoxin S6b was observed in the microsomal fractions from porcine thoracic aorta, and two vasoconstrictive peptides with strikingly homologous structures, sarafotoxin (SRT) and endothelin (ET), interact with a common receptor of the vasculature. The order of the potency of an each endothelin or sarafotoxin analogue as a competitor against 125I-sarafotoxin S6b binding was ET-1 greater than ET-2 greater than SRT S6b greater than ET-3 much greater than SRT S6c. The hydrophobic carboxyl-terminal tail and intramolecular disulfide bridges are essential for the binding activity. In addition, Ser4, Ser5 and Lys9 seem to be important for the activity while the 6th residue does not affect the activity.
Interferometer Mirrors With Holes On-axis (2005)

Placing holes on-axis in the mirrors of an optical interferometer used for a free-electron laser (FEL) oscillator has several desirable effects. For a given amount of power generated at saturation, the peak power density on the mirrors is decreased, thereby ameliorating the problem of mirror damage; the electron beam can be introduced into the cavity in a collinear fashion; and the small-signal gain can be increased. Surprisingly, these holes may be quite large without a significant increase in cavity loss. This is a consequence of the fact that higher-order modes are generated which sum to a null of the field at the position of the holes.
Towards a Wireless Battery Management System: Evaluation of Antennas and Radio Channel Measurements Inside a Battery Emulator (2014)

The Battery Management System (BMS) is designed to monitor and control the traction lithium-ion battery for hybrid and electric vehicles. Within the battery pack, a communication network is established between the Battery Control Unit (BCU) and the Cell Sensor Units (CSU) to collect the information measured from each individual cell. The current BMS communications systems employ standard bus systems (like CAN-Bus) and therefore require the installation of a very large amount of additional wiring, which creates a negative impact on cost, weight, construction complexity, and the galvanic isolation of the cells. In the context of the IntLiIon project, we study different alternatives to solve this problem. In this work, we are presenting a feasibility study of a wireless approach for the BMS communications system. This study comprises the evaluation and measurement of different antenna types and frequency ranges for the wireless channel inside the battery pack.
Manipulating Connexin Communication Channels: Use of Peptidomimetics and the Translational Outputs (2012)

Gap junctions are key components underpinning multicellularity. They provide cell to cell channel pathways that enable direct intercellular communication and cellular coordination in tissues and organs. The channels are constructed of a family of connexin (Cx) membrane proteins. They oligomerize inside the cell, generating hemichannels (connexons) composed of six subunits arranged around a central channel. After transfer to the plasma membrane, arrays of Cx hemichannels (CxHcs) interact and couple with partners in neighboring attached cells to generate gap junctions. Cx channels have been studied using a range of technical approaches. Short peptides corresponding to sequences in the extra- and intracellular regions of Cxs were used first to generate epitope-specific antibodies that helped studies on the organization and functions of gap junctions. Subsequently, the peptides themselves, especially Gap26 and -27, mimetic peptides derived from each of the two extracellular loops of connexin43 (Cx43), a widely distributed Cx, have been extensively applied to block Cx channels and probe the biology of cell communication. The development of a further series of short peptides mimicking sequences in the intracellular loop, especially the extremity of the intracellular carboxyl tail of Cx43, followed. The primary inhibitory action of the peptidomimetics occurs at CxHcs located at unapposed regions of the cell's plasma membrane, followed by inhibition of cell coupling occurring across gap junctions. CxHcs respond to a range of environmental conditions by increasing their open probability. Peptidomimetics provide a way to block the actions of CxHcs with some selectivity. Furthermore, they are increasingly applied to address the pathological consequences of a range of environmental stresses that are thought to influence Cx channel operation. Cx peptidomimetics show promise as candidates in developing new therapeutic approaches for containing and reversing damage inflicted on CxHcs, especially in hypoxia and ischemia in the heart and in brain functions.
