Eliminating ground current in a transformerless photovoltaic application (2007)

A single phase converter can be used for low-power grid connected applications. In photovoltaic applications it is possible to remove the transformer in the inverter in order to reduce losses, costs and size. Galvanic connection of the grid and the DC sources in transformerless systems can introduce additional leakage currents because of the earth parasitic capacitance. This currents increase conducted and radiated electromagnetic emissions, harmonics injected in the utility grid and system losses. Amplitude and spectrum of ground current depends on the converter topology, on the switching strategy and on the resonant circuit formed by the ground capacitance, the converter, the AC filter and the grid. In this paper, the leakage current in a 1.5 kW photovoltaic installation is measured. The installation includes a string of sixteen panels, a full bridge inverter and a LCL filter. Influence of inverter topology and modulation strategy on the magnitude of the leakage current is presented. Finally, the use of neutral point clamped inverters in transformerless photovoltaic applications is studied.
HeatWatch: Improving 3D NAND Flash Memory Device Reliability by Exploiting Self-Recovery and Temperature Awareness (2018)

NAND flash memory density continues to scale to keep up with the increasing storage demands of data-intensive applications. Unfortunately, as a result of this scaling, the lifetime of NAND flash memory has been decreasing. Each cell in NAND flash memory can endure only a limited number of writes, due to the damage caused by each program and erase operation on the cell. This damage can be partially repaired on its own during the idle time between program or erase operations (known as the dwell time), via a phenomenon known as the self-recovery effect. Prior works study the self-recovery effect for planar (i.e., 2D) NAND flash memory, and propose to exploit it to improve flash lifetime, by applying high temperature to accelerate self-recovery. However, these findings may not be directly applicable to 3D NAND flash memory, due to significant changes in the design and manufacturing process that are required to enable practical 3D stacking for NAND flash memory. In this paper, we perform the first detailed experimental characterization of the effects of self-recovery and temperature on real, state-of-the-art 3D NAND flash memory devices. We show that these effects influence two major factors of NAND flash memory reliability: (1) retention loss speed (i.e., the speed at which a flash cell leaks charge), and (2) program variation (i.e., the difference in programming speed across flash cells). We find that self-recovery and temperature affect 3D NAND flash memory quite differently than they affect planar NAND flash memory, rendering prior models of self-recovery and temperature ineffective for 3D NAND flash memory. Using our characterization results, we develop a new model for 3D NAND flash memory reliability, which predicts how retention, wearout, self-recovery, and temperature affect raw bit error rates and cell threshold voltages. We show that our model is accurate, with an error of only 4.9%. Based on our experimental findings and our model, we propose HeatWatch, a new mechanism to improve 3D NAND flash memory reliability. The key idea of HeatWatch is to optimize the read reference voltage, i.e., the voltage applied to the cell during a read operation, by adapting it to the dwell time of the workload and the current operating temperature. HeatWatch (1) efficiently tracks flash memory temperature and dwell time online, (2) sends this information to our reliability model to predict the current voltages of flash cells, and (3) predicts the optimal read reference voltage based on the current cell voltages. Our detailed experimental evaluations show that HeatWatch improves flash lifetime by 3.85× over a baseline that uses a fixed read reference voltage, averaged across 28 real storage workload traces, and comes within 0.9% of the lifetime of an ideal read reference voltage selection mechanism.
Topical silver and gold nanoparticles complexed with <i>Cornus mas</i> suppress inflammation in human psoriasis plaques by inhibiting <scp>NF</scp>‐κB activity (2018)

New biomaterials based on nanoparticles (NPs) carrying polyphenols-rich extracts (Cornus mas) recently showed promising anti-inflammatory activity in psoriasis. We aimed to understand how topically delivered silver and gold nanoparticles complexed with Cornus mas (Ag-NPs-CM, Au-NPs-CM) modulate inflammation in psoriasis at cellular and molecular level. The impact on psoriatic inflammation was assessed in vitro on pro-inflammatory macrophages, by clinical score, high-frequency ultrasonography and immunohistology of psoriasis plaques treated with Ag-NPs-CM, Au-NPs-CM or control. Incubation of pro-inflammatory macrophages with nanoparticles significantly decreased the release of NO, IL-12 and TNF-α. Immunofluorescence confirmed that nanoparticles significantly reduced CD68-positive macrophages and their IL-12 and TNF-α production in human psoriasis plaques. NPs-CM appear to repress NF-κB activation in macrophages, inhibiting the production of pro-inflammatory factors with causal role in psoriasis. Ag and Au NPs-CM represent a novel nanoparticle-based "green" technology which may provide an efficient tool for modern psoriasis therapy, circumventing immunosuppression-related side effects of biologicals.
Role of the apical stem in maintaining the structure and function of adenovirus virus-associated RNA (1992)

Adenovirus virus-associated (VA) RNAI maintains efficient protein synthesis during the late phase of infection by preventing the activation of the double-stranded-RNA-dependent protein kinase, DAI. A secondary structure model for VA RNAI predicts the existence of two stems joined by a complex stem-loop structure, the central domain. The structural consequences of mutations and compensating mutations introduced into the apical stem lend support to this model. In transient expression assays for VA RNA function, foreign sequences inserted into the apical stem were fully tolerated provided that the stem remained intact. Mutants in which the base of the apical stem was disrupted retained partial activity, but truncation of the apical stem abolished the ability of the RNA to block DAI activation in vitro, suggesting that the length and position of the stem are both important for VA RNA function. These results imply that VA RNAI activity depends on secondary structure at the top of the apical stem as well as in the central domain and are consistent with a two-step mechanism involving DAI interactions with both the apical stem and the central domain.
The Role of  H 2 S  in the Corrosion and Hydrogen Embrittlement of Steel (1982)

Hydrogen permeation in a high strength ferritic steel was shown to depend on the passivity of the surface and the presence of . In the case where is not present, an oxide on the surface of the steel reduced the kinetics of the proton discharge rate and, even more so, the kinetics of the molecular hydrogen evolution rate. Thus, a high percentage of hydrogen permeated the steel. After the oxide was removed, there was an increased proton discharge rate and an equally increased hydrogen evolution rate, thus resulting in very low percentage of hydrogen permeation. When was present, the hydrogen discharge reaction remained high but the recombination reaction was suppressed so the percent of permeation was very high. Thus, plays a multiple role in increasing hydrogen permeation of passivated steel in slightly acidic environments. It increases the rates of iron corrosion and proton discharge and poisons the hydrogen evolution reaction on the depassivated surface, thereby permitting a large fraction of hydrogen atoms to enter the metal.
Bacterial Conversion of a Waste Stream Containing Methyl-2-hydroxyisobutyric Acid to Biodegradable Polyhydroxyalkanoate Polymers (1994)

Bacteria were used to study the feasibility of converting a liquid organic manufacturing waste stream to solid biodegradable polyhydroxyalkanoate (PHA) polymers. Bacteria were isolated from activated sludge obtained from an acrylate manufacturing plant. Representatives of several genera, including Bacillus, Pseudomonas, and Alcaligenes were found to be well-adapted to growth on methyl-2-hydroxyisobutyric acid, a major component of the waste stream generated from distillation of crude methyl methacrylate. Non-adapted mixed cultures of bacteria obtained from municipal sludge and other well-studied PHA-accumulating bacteria were not able to survive in the presence of organic waste substrates under conditions where adapted bacteria grew vigorously. A preliminary economic analysis determined that the costs of using aqueous waste as a carbon feedstock was similar to the cost of using the conventional PHA production substrate, glucose. Further study of the kinetics of bacterial substrate conversion and of the feasibility of designing the physical plant for a waste conversion process are necessary to determine whether the concept of hazardous waste bioconversion to biodegradable products is a viable approach to chemical or agricultural waste management.
Polymer-based device for efficient mixing of viscoelastic fluids (2006)

We demonstrated rapid mixing of viscoelastic fluids in microchannels constructed based on polymethyl methacrylate. Viscoelastic mixing without diffusion was achieved with an effective mixing length of less than 5mm and a relatively fast flow rate. With an abrupt contraction microgeometry (8:1 contraction ratio), we mixed two different viscoelastic fluids experimentally at very low Reynolds numbers, but enormous Peclet and elasticity numbers. This special geometrical configuration triggers flow instability, leading to turbulent and efficient mixing. This flow regime has negligible inertia effects but significant elastic effects.
Formononetin, a methoxy isoflavone, enhances bone regeneration in a mouse model of cortical bone defect (2017)

The bone regeneration and healing effect of formononetin was evaluated in a cortical bone defect model that predominantly heals by intramembranous ossification. For this study, female Balb/c mice were ovariectomised (OVx) and a drill-hole injury was generated in the midfemoral bones of all animals. Treatment with formononetin commenced the day after and continued for 21 d. Parathyroid hormone (PTH1-34) was used as a reference standard. Animals were killed at days 10 and 21. Femur bones were collected at the injury site for histomorphometry studies using microcomputed tomography (μCT) and confocal microscopy. RNA and protein were harvested from the region surrounding the drill-hole injury. For immunohistochemistry, 5 µm sections of decalcified femur bone adjoining the drill-hole site were cut. μCT analysis showed that formononetin promoted bone healing at days 10 and 21 and the healing effect observed was significantly better than in Ovx mice and equal to PTH treatment in many aspects. Formononetin also significantly enhanced bone regeneration as assessed by calcein-labelling studies. In addition, formononetin enhanced the expression of osteogenic markers at the injury site in a manner similar to PTH. Formononetin treatment also led to predominant runt-related transcription factor 2 and osteocalcin localisation at the injury site. These results support the potential of formononetin to be a bone-healing agent and are suggestive of its promising role in the fracture-repair process.
Possibilités de développement de la pêche de la crevette côtière en Guyane - Première campagne de prospection (17 février au 1er mars 1975) (1975)

En Guyane, la crevette côtière Xyphopenaeus kroyeri, localement nommée "sea-bob", fait l'objet d'une pêche artisanale traditionnelle au moyen d'engins fixes, les barrières chinoises (fig. 1 et 2). Mais cette pêche est très limitée dans l'espace et dans le temps.
Pipelined computation of scalar multiplication in elliptic curve cryptosystems (extended version) (2006)

In the current work, we propose a pipelining scheme for implementing elliptic curve cryptosystems (ECC). The scalar multiplication is the dominant operation in ECC. It is computed by a series of point additions and doublings. The pipelining scheme is based on a key observation: to start the subsequent operation, one need not wait until the current one exits. The next operation can begin while a part of the current operation is still being processed. To our knowledge, this is the first attempt to compute the scalar multiplication in such a pipelined manner. Also, the proposed scheme can be made resistant to sidechannel attacks (SCA). Our scheme compares favorably with all SCA-resistant sequential and parallel methods.
Clinical significance of platelet derived growth factor-C and -D in gastric cancer (2015)

Platelet-derived growth factor (PDGF)-C and PDGF-D are frequently upregulated in human cancers and play important roles in tumor progression, angiogenesis and metastasis. However, the distribution, frequency and prognostic value of PDGF-C and PDGF-D expression in gastric cancer have not been clarified. The present study evaluated the association between expression of PDGF-C and PDGF-D, clinicopathological factors and outcomes, in patients with gastric cancer. Gastric adenocarcinoma tumor samples were obtained from 204 patients who underwent curative gastrectomy between 2003 and 2007. The expression of PDGF-C and PDGF-D was analyzed by immunohistochemical staining. High expression of PDGF-C and PDGF-D was detected in 114 (56%) and 151 (74%) tumors, respectively. PDGF-D expression was significantly associated with tumor depth (P=0.039), histopathology (P<0.01), tumor stage (P=0.01) and recurrence (P<0.01), whereas PDGF-C expression correlated only with histopathology (P=0.05). High PDGF-D expression was also associated with significantly shorter relapse-free survival (RFS) time (P<0.01), whilst high PDGF-C expression was associated with marginally, but not significantly, shorter RFS (P=0.10). On multivariate analysis, high PDGF-D expression was determined to be an independent prognostic factor (hazard ratio, 3.3; 95% confidence interval, 1.20-9.4; P=0.02). These findings indicate that high PDGF-D expression is strongly associated with tumor progression, recurrence, distant metastasis and poor outcomes in patients with gastric cancer. PDGF-D may therefore be an independent prognostic factor and a novel therapeutic target.
New microstrip slot radiator for medical applications (1980)

Enzymatic synthesis of oleyl oleate in dense fluids (1995)

Abstract Esterification between oleic acid and oleyl alcohol, catalyzed by the Mucor miehei immobilized lipase in a batch‐stirred tank reactor with supercritical carbon dioxide as solvent produced higher reaction rates at supercritical conditions than in the solvent‐free system. A continuous fixed‐bed reactor was designed based on the results obtained from batch experiments. At 150 bar, 40°C, and with water activity 0.46% w/w, the activity of the enzyme preparation is practically unchanged when CO 2 was used as solvent. The addition of small amounts of water increases the conversion rate. The higher conversion also was observed at longer residence time. When n ‐butane was used as reaction medium, a decrease in conversion was observed.
A study of next generation metro-access hybrid scalable network by using PLZT ultra high speed optical wavelength selective switch (2011)

We have studied a novel optical access network with PLZT (Plomb Lanthanum Zirconate Titanate) optical switches, called ActiON (Active Optical Network), as a next generation access network to replace PON (Passive Optical Network). On the other hand, energy consumption of the present network becomes an important problem today. To resolve this problem, we study an energy efficient metro-access hybrid network by using ActiON. Also, it is necessary to extend a bandwidth capacity of ActiON to realize a scalable network. In this paper, we mainly focus on an energy consumption and a scalability. As a result, the proposed next generation metro-access hybrid scalable network accommodates 600000 users. In the evaluation, we show that proposed network reduces 65 % of energy consumption compare to the present network. Furthermore, blocking ratio of proposed network is lower than a quality assurance of the Internet service in any cases.
The Molen compiler for reconfigurable architectures (2007)

In this dissertation, we present the Molen compiler framework that targets reconfigurable architectures under the Molen Programming Paradigm. More specifically, we introduce a set of compiler optimizations that address one of the main shortcomings of the reconfigurable architectures, namely the reconfiguration overhead. The proposed optimizations are based on data flow analyses at intraprocedural and interprocedural level and take into account the competition for reconfigurable hardware resources and the spatiotemporal mapping. The hardware configuration instructions are scheduled in advance of hardware execution instructions, in order to exploit the available parallelism between the hardware configuration phase and the sequential execution on the core processor. The intraprocedural optimization uses the min s-t cut graph algorithm to reduce the number of executed hardware configurations by identifying the redundant hardware configurations. We also introduce two allocation algorithms for the reconfigurable hardware resources that aim to minimize the total reconfigured area and to maximize the overall performance gain. Based on profiling results and software/hardware estimations, the compiler optimizations and allocation algorithms generate optimized code for the spatio-temporal constraints of the target reconfigurable architecture and input application. Additionally, they guide the selection of hardware/software execution of the operations candidate for reconfigurable hardware execution. In order to evaluate the Molen compiler, we first present an experiment with a multimedia benchmark application compiled by the Molen compiler and executed on the Molen polymorphic media processor with an overall speedup of 2.5 compared to the pure software execution. Subsequently, we estimate that the intraprocedural compiler optimization contributes to up to 94% performance improvement compared to the pure software execution, while the intraprocedural compiler optimization and the allocation algorithms significantly reduce the number of executed reconfigurations for the considered benchmarks. Finally, we determine that the important performance impact of our compiler optimizations and allocation algorithms increases for the future faster FPGAs.
Crystallographic and Solution Studies of an Activation Loop Mutant of the Insulin Receptor Tyrosine Kinase (2001)

The tyrosine kinase domain of the insulin receptor is subject to autoinhibition in the unphosphorylated basal state via steric interactions involving the activation loop. A mutation in the activation loop designed to relieve autoinhibition, Asp-1161 --> Ala, substantially increases the ability of the unphosphorylated kinase to bind ATP. The crystal structure of this mutant in complex with an ATP analog has been determined at 2.4-A resolution. The structure shows that the active site is unobstructed, but the end of the activation loop is disordered and therefore the binding site for peptide substrates is not fully formed. In addition, Phe-1151 of the protein kinase-conserved DFG motif, at the beginning of the activation loop, hinders closure of the catalytic cleft and proper positioning of alpha-helix C for catalysis. These results, together with viscometric kinetic measurements, suggest that peptide substrate binding induces a reconfiguration of the unphosphorylated activation loop prior to the catalytic step. The crystallographic and solution studies provide new insights into the mechanism by which the activation loop controls phosphoryl transfer as catalyzed by the insulin receptor.

Management workflow for consultants in a company (2011)

The present paper is an effort to partially automate the workflow to hire an external consultant in the cases when the existing expertise is not enough. Usually this happens in but is not limited to major worldwide companies. For the implementation we use a virtual intranet portal custom built for the Ford Motor Company plant in Craiova. Although it is used for development, the main idea was to make it deployable in production with changes related to the server environment architecture - in production we are no longer talking about a single machine.
