Effect of Vibrations, Displacement, Pressure, Temperature and Humidity on the Resistance and Impedance of the Shockproof Resistors Based on Rubber and Jelly (NiPc–CNT–Oil) Composites (2022)

Here, we present the design, fabrication and characterization of shockproof rubber-jelly (NiPc-CNT-oil) composite-based resistors. To fabricate the resistors, gels of CNT and NiPc with edible oil were prepared and deposited on a flexible rubber substrate using rubbing-in technique. The devices' resistance and impedance were investigated under the effect of pressure, displacement, humidity, temperature and mechanical vibrations. The resistance and the impedance decreased, on average, by 1.08 times under the effect of pressure (up to 850 gf/cm<sup>2</sup>) and by 1.04 times under the effect of displacement (up to 50 µm). Accordingly, upon increasing the humidity from 60% to 90% RH, the resistance and impedance decreased by up to 1.04 times, while upon increasing the temperature from 25 °C to 43 °C, the resistance and impedances also decreased by up to 1.05 times. Moreover, under the effect of vibration, a decrease in resistance and impedance, by up to 1.03 times, was observed. The investigated samples can potentially be used as prototypes for the development of shockproof jelly electronic-based devices in particular resistors. The technological achievement in the fabrication of these devices is the use of edible organic oil, which allows for the fabrication of uniform jelly films of organic materials that cannot be realized simply by mixing "dry" ingredients. Especially, we highlight that edible organic oil is environmentally friendly, unlike some other inorganic oils that are used in practice.

Administration of Imiquimod, an Interferon Inducer, in Asymptomatic Human Immunodeficiency Virus‐Infected Persons to Determine Safety and Biologic Response Modification (1998)

A phase I study to determine safety, maximum tolerated dose, and biologic response during multiple once-a-week administration of oral imiquimod, an immune response modifier, was conducted in 12 adults with early human immunodeficiency virus (HIV) infection. All completed the dose-escalation phase of weekly dosing at 100-mg increments and received at least one maintenance dose, 100 mg below the patient's toxic dose, for 12 weeks. Dose-limiting toxicity occurred in 3 patients at 200-mg, 5 at 300-mg, and 3 at 400-mg dose levels. One tolerated the 500-mg dose without dose-limiting toxicity. Dose-limiting toxicities included fatigue, fever, malaise, increased transaminases, hypotension, vomiting, and depression. Seven of 12 completed 12 weeks of maintenance. At > or = 200 mg of imiquimod, all patients had biologic responses, measured by elevations in serum interferon, beta2-microglobulin, and neopterin levels. Imiquimod induced pronounced levels of circulating interferon in asymptomatic HIV-infected persons, with variable effect on virus load.
Comparison of CDMA spatio-temporal receivers structures (2002)

This paper reports an analysis of the performance of code division multiple access (CDMA) system employing spatio-temporal adaptive receiving filters at the base station. We show that taking into account the spatial and temporal statistical properties of the interference is a very interesting and efficient way of increasing the cell capacity. Since a pilot sequence is used to estimate the receiving filter, the influence of the number of available pilot symbols on the receiver's performance is studied.
Cloning, nucleotide sequence, and expression of a gene encoding an adhesin subunit protein of Helicobacter pylori (1993)

Gene hpaA, which codes for the receptor-binding subunit of the N-acetylneuraminyllactose-binding fibrillar hemagglutinin (NLBH) of Helicobacter pylori, was cloned and sequenced. The protein expressed by hpaA, designated HpaA, was identified as the adhesin subunit on the basis of its fetuin-binding activity and its reactivity with a polyclonal, monospecific rabbit serum prepared against NLBH purified from H. pylori. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis and Western blots (immunoblots) showed that the cloned adhesin has the same molecular weight (20,000) as that found on H. pylori. Also, HpaA contains a short sequence of amino acids (KRTIQK) which are all either identical or functionally similar to those which compose the sialic acid-binding motif of Escherichia coli SfaS, K99, and CFA/I. Affinity-purified antibody specific for a 12-residue synthetic peptide that included this sequence blocked the hemagglutinating activity of H. pylori and was shown by immuno-gold electron microscopy to react with almost transparent material on unstained H. pylori cells, which is consistent with previous observations concerning the location and morphology of the NLBH.
An immunological determinant of RNase P protein is conserved between Escherichia coli and humans. (1989)

RNase P, an enzyme with RNA and protein subunits, cleaves tRNA precursor molecules to form the 5' termini of mature tRNAs in both prokaryotes and eukaryotes. Rabbit antibodies made against the protein subunit, C5 protein, of Escherichia coli RNase P bound RNase P protein from E. coli and Bacillus subtilis in immunoblots and solid-phase immunoassays. These rabbit anti-C5 antibodies also bound a protein (Mr approximately 40,000) in preparations of RNase P from human (HeLa) cells and depleted the enzymatic activity from preparations of RNase P from both human and E. coli cells. Finally, rabbit anti-C5 antibodies immunoprecipitated from crude extracts of human cells a ribonucleoprotein complex containing H1 RNA, the putative RNA component of human RNase P. These results show that an antigenic determinant is shared by C5 protein from E. coli RNase P and a protein component of RNase P from human cells.
Exploitation of steel slags in clay bricks (2002)

The feasibility of steel slag recycling in bricks was assessed through laboratory trials on three different topologies of wastes and clay bodies. The use of slag, previously ground below 3 mm, is substantially possible for additions of 2-3% without particular hindrances of technological nature. Additions of up to 5-670 seem to be practicable, even though with a porosity increase and a deterioration of the mechanical properties of both unfired and fired products. Larger amounts of slag are decidedly inadvisable for the changes in the chemical and physical characteristics of products.

DIC image reconstruction using an energy minimization framework to visualize optical path length distribution (2016)

Label-free microscopy techniques have numerous advantages such as low phototoxicity, simple setup and no need for fluorophores or other contrast materials. Despite their advantages, most label-free techniques cannot visualize specific cellular compartments or the location of proteins and the image formation limits quantitative evaluation. Differential interference contrast (DIC) is a qualitative microscopy technique that shows the optical path length differences within a specimen. We propose a variational framework for DIC image reconstruction. The proposed method largely outperforms state-of-the-art methods on synthetic, artificial and real tests and turns DIC microscopy into an automated high-content imaging tool. Image sets and the source code of the examined algorithms are made publicly available.

A homogeneous, liposome-based signal amplification for assays involving enzymes. (1988)

Abstract Exploiting the fact that phosphatidylethanolamine (PE) liposome can be stabilized by a membrane lipid or protein, and that destruction of this stabilizer leads to rapid lysis of the liposome, we have designed a liposome-based signal enhancement mechanism for assays that involve enzyme as the final read-out step. Stable liposomes with entrapped glucose-6-phosphate dehydrogenase (G6PDH) were prepared with unsaturated PE stabilized with 5 mol percent of ganglioside GM1. Addition of beta-galactosidase caused rapid (3-5 min) lysis of liposomes, revealing the latent G6PDH activity, owing to the enzymatic degalactosylation of GM1. We have used Microgenic's CEDIA assay for digoxin as an example. The magnitude of signal was 25 mA/min per microgram of digoxin per liter for the unamplified assay and 1000 mA/min per microgram of digoxin per liter for the liposome-enhanced assay--i.e., a 40-fold amplification. This simple, rapid, and homogeneous signal-amplification mechanism is likely to be useful in many enzyme-dependent assays, such as ELISA, CEDIA, gene-probe assays, and immunoliposome assays.
Observation of photorefractivity in a fullerene-doped polymer composite (1992)

A photorefractive effect was observed in a fullerene (${\mathrm{C}}_{60}$) -doped organic composite containing polyvinylcarbazole and a second-order molecule, diethyl-amino-nitrostyrene (DEANST). Electro-optic modulation and degenerate four-wave mixing experiments were conducted. The material shows relatively high electro-optic coefficient, photocharge generation quantum efficiency, and photorefractive diffraction efficiency.
Solution Sets for DCOPs and Graphical Games: Metrics and Bounds. (2006)

A distributed constraint optimization problem (DCOP) is a formalism that captures the rewards and costs of local interactions within a team of agents, each of whom is choosing an individual action. When rapidly selecting a single joint action for a team, we typically solve DCOPs (often using locally optimal algorithms) to generate a single solution. However, in scenarios where a set of joint actions (i.e. a set of assignments to a DCOP) is to be generated, metrics are needed to help appropriately select this set and e#ciently allocate resources for the joint actions in the set. To address this need, we introduce k-optimality, a metric that captures the desirable properties of diversity and relative quality of a set of locally-optimal solutions using a parameter that can be tuned based on the level of these properties required. To achieve e#ective resource allocation for this set, we introduce several upper bounds on the cardinalities of k-optimal joint action sets. These bounds are computable in constant time if we ignore the graph structure, but tighter, graphbased bounds are feasible with higher computation cost. Bounds help choose the appropriate level of k-optimality for settings with fixed resources and help determine appropriate resource allocation for settings where a fixed level of k-optimality is desired. In addition, our bounds for a 1-optimal joint action set for a DCOP also apply to the number of pure-strategy Nash equilibria in a graphical game of noncooperative agents.
Building a Common Catalog for Cultural Heritage Repositories (2005)

ABSTRACT The Ohio Memory Online Scrapbook is a common catalog with records from 328 cultural heritage repositories. Creating the online scrapbook, however, did not involve lengthy discussions of cataloging issues among the participants. Decisions about how materials would be described were made by staff at the Ohio Historical Society and were influenced by a commitment to integrating collections of different formats from multiple repositories, a centralized approach, use of Dublin Core, development of metadata standards, and adoption of controlled vocabularies. Participating institutions, and end users, are more concerned with the results of the cataloging process than the details of description.
Electrical Properties of β- and γ-Type Manganese (IV) Oxides (1988)

A detailed comparison of the electrical properties between β-type and γ-type manganese (IV) oxides is presented on high-purity samples. Thermal stability of MnO2 in terms of its transition to Mn2O3 was examined by TG and β-type was found to be more stable the γ-type. The temperature dependence of Seebeck coeffecient and resistivity was measured. The effect of annealing temperature on the resistivity was also studied. Both β- and γ-MnO2 showed n-type semiconduction, but the differences found were: (1) β-type showed higher conductivity than γ-type; (2) The temperature dependence of resistivity for β-MnO2 was smaller than that of γ-MnO2; (3) Resistivity at 100°C showed a “U” shape relation with annealing temperature for γ-MnO2, while it increased monotonically with increasing annealing temperature for β-MnO2. These differences were explained by the distinctions in crystal structure based on a hopping conduction model. β-type is built up with MnO6 octahedron chains having 1×1 tunnels and shows high electrical conductivity. γ-type has the intergrowth structure of β-type and groutite containing 1×1 and 1×2 tunnels, and has low electrical conductivity. Annealing of γ-MnO2 at high temperature shifts 1×2 tuunels to 1×1 tunnels, and the structure approaches β-type. This structural change was explained to be responsible for the “U” shape relation between resistivity and annealing temperature.
A Rotary Crane Control Method Based on a Skillful Operator's Knowledge (1997)

A crane active on the construction site is the loading machine that transports load to a fixed position by doing the turn movement centering on a part of the boom. The fulcrum of the rope draws circular arc tracks in such turn cranes and the behavior of load is very complex. Therefor the operations that maintain sway of a turn crane depend on an operator's skill. We propose anti-sway control method of the rotary crane based on a skillful operator's knowledge. The computer simulation and experiment of the loading control were executed by using this method. It was confirmed that the proposed method is effective.
Effect of Charge on Transport and Distribution of Contrast Agents in Cartilage (2000)

Introduction An MRI technique has been developed for imaging glycosaminoglycan (GAG) in cartilage, based on the fact that GAGS have abundant charged groups that confer a fvted negative charge to the matrix. A negatively charged contrast agent (i.e., GdDTPA’) will therefore distribute within cartilage inversely to the GAG concentration(1-4). The technique relies upon the assumption that the Gd-DTPA’has had time to penetrate the cartilage matrix. In order to investigate the effects of charge on the penetration of contrast agent into cartilage and on the fmal distribution of contrast, we: (1)measured the diffusion coefficient of Gd-DTPA’(Magnevist, Berlex) and the nonionic gadoteridol, Gd(HPD03A) (ProHance, Bracco) in control (GAG rich, hence charged) cartilage and (2) monitored the kinetics of contrast agent wash-in and fmal concentration in control and GAG depleted cartilage.
Vascular Endothelial Function in Midlife/Older Adults Classified According to 2017 American College of Cardiology/American Heart Association Blood Pressure Guidelines (2020)

Background Impaired endothelial function is thought to contribute to the increased cardiovascular risk associated with above-normal blood pressure (BP). However, the association between endothelial function and BP classified by 2017 American College of Cardiology/American Heart Association guidelines is unknown. Our objective was to determine if endothelial function decreases in midlife/older adults across the 2017 American College of Cardiology/American Heart Association guidelines BP classifications and identify associated mechanisms of action. Methods and Results A retrospective analysis of endothelial function (brachial artery flow-mediated dilation) from 988 midlife/older adults (aged 50+ years) stratified by BP status (normal BP; elevated BP; stage 1 hypertension; stage 2 hypertension) was performed. Endothelium-independent dilation (sublingual nitroglycerin), reactive oxygen species-mediated suppression of endothelial function (∆brachial artery flow-mediated dilation with vitamin C infusion), and endothelial cell and plasma markers of oxidative stress and inflammation were assessed in subgroups. Compared with normal BP (n=411), brachial artery flow-mediated dilation was 12% (<i>P</i>=0.04), 15% (<i>P</i><0.01) and 20% (<i>P</i><0.01) lower with elevated BP (n=173), stage 1 hypertension (n=248) and stage 2 hypertension (n=156), respectively, whereas endothelium-independent dilation did not differ (<i>P</i>=0.14). Vitamin C infusion increased brachial artery flow-mediated dilation in those with above-normal BP (<i>P</i>≤0.02) but not normal BP (<i>P</i>=0.11). Endothelial cell p47<sup>phox</sup> (<i>P</i><0.01), a marker of superoxide/reactive oxygen species-generating nicotinamide adenine dinucleotide phosphate oxidase, and circulating interleukin-6 concentrations (<i>P</i>=0.01) were higher in individuals with above-normal BP. Conclusions Vascular endothelial function is progressively impaired with increasing BP in otherwise healthy adults classified by 2017 American College of Cardiology/American Heart Association guidelines. Impaired endothelial function with above-normal BP is mediated by excessive reactive oxygen species signaling associated with increased endothelial expression of nicotinamide adenine dinucleotide phosphate oxidase and circulating interleukin-6.

Ubiquitin Fusion Approach to Heterologous Gene Expression in Yeast (1991)

The ubiquitin fusion approach to gene expression in eukaryotic systems allows the production of heterologous proteins that are cleaved precisely in vivo from the ubiquitin fusion partner by an endogenous ubiquitin-specific hydrolase. Alternatively, ubiquitin fusions can be isolated from bacterial hosts, and cleaved by the hydrolase in vitro. In each case, the system gives recombinant proteins that contain authentic amino termini. We have found the system to be of particular utility for the production of human gamma interferon (γIFN) and α1-proteinase inhibitor (α1-PI). We have also used the system for the production of regions of the human immunodeficiency virus type-1 (HIV1) genome that were previously expressed at only low levels in yeast. These include domains of the HIV1 env gene and also the region of the HIV1 pol gene that encodes the HIV1 integrase enzyme. Surprisingly, for one of the env proteins we were able to isolate a product in which the amino-terminal Glu residue was modified by addition of an Arg residue. This arginyl-tRNA-protein-transferase catalyzed process had previously only been observed for short-lived intermediates in the ubiquitin-dependent proteolytic degradation pathway. The HIV1 integrase was found to contain the authentic amino terminus (Phe.Leu.Asn...) previously reported for virion-associated integrase.
5-FU resistant EMT-like pancreatic cancer cells are hypersensitive to photochemical internalization of the novel endoglin-targeting immunotoxin CD105-saporin (2017)

Our findings suggested that autophagy is an important resistance mechanism against the chemotherapeutic drug 5-FU in pancreatic cancer cells, and that inhibition of the autophagy process, either by CQ or lysosomal photodamage, can contribute to increased sensitivity to 5-FU. For the first time, we demonstrate the promise of PCI-based targeting of CD105 in site-specific elimination of 5-FU resistant pancreatic cancer cells in vitro. In conclusion, PCI-based targeting of CD105 may represent a potent anticancer strategy and should be further evaluated in pre-clinical models.
CD4 cell and CD8 cell-mediated resistance to HIV-1 infection in exposed uninfected intravascular drug users in Vietnam (2003)

Reduced PBMC susceptibility to HIV-1 infection was associated with resistance to infection in exposed uninfected IDU. Distinct mechanisms are involved in in-vitro resistance and may contribute to the apparent protection from HIV-1 transmission in this systemically exposed population.
