Computational analysis of wireless inductive power transfer for charging light-duty electric vehicles (2020)

Wireless chargers can help make electric vehicles more comfortable, which would make electric cars more attractive to consumers, thereby increasing the number of electric cars and helping to reduce greenhouse gases and other emissions locally. Therefore, this study aimed to investigate and improve the performance and efficiency of the wireless charger. The research focused on a racetrack-shaped, inductive, wireless charger for electric vehicles that is capable of 20 kW charging power. The study utilized numerical FEM computation to simulate the charger.&#13;\n &#13;\nIn the study, the operation of the charger was simulated using COMSOL Multiphys-ics 5.4 software, and MATLAB software was used to analyze and present the results. The study found that the vehicle's driving speed during wireless charging does not affect the mutual inductance of the charger. It was also found that it is possible to improve the charging device developed in the previous study by reforming the ferrite cores of the charging device. Remodeling of the ferrite core provided the same mutual inductance with a lower mass than the original structure. Also, the study compared two different ways to calculate the efficiency of the charger and evaluated sufficient mesh density for the FEM calculation. The study also addressed the selection criteria and material choices of the wireless charger.&#13;\n&#13;\nBased on the research results, it was concluded that wireless chargers are a practical and effective means for charging electric cars. Chargers are capable of both high power (20 kW) and high efficiency (over 90%), and enable charging during vehicle movement without breakable cables and contacts. It was also concluded that computer-based FEM programs such as COMSOL could improve the performance of wireless chargers and provide new innovative solutions.
Rapid DNA Library Construction for Functional Genomic and Metagenomic Screening (2007)

A rapid protocol was developed for constructing plasmid libraries from small quantities of genomic/metagenomic DNA. The technique utilizes linker amplification with topoisomerase cloning and allows for inducible transcription in Escherichia coli. As proof of principle, several anti-Bacillus lysins were cloned from bacteriophage genomes and an aerolysin was cloned from a metagenomic sample.
Solidification pathways and phase equilibria in the Mo–Ti–C ternary system (2020)

Abstract The liquidus surface projection and isothermal section at 1,800°C in the Mo–Ti–C ternary system are examined using arc-melted alloys. A ternary transition peritectic reaction (L + Mo 2 C → Mo + TiC) takes place during solidification, which is apparently different from the ternary eutectic reaction (L → Mo + TiC + Mo 2 C) observed in a previous report. Since the composition of the eutectic reaction (L → Mo + TiC) shifts toward the Mo–Ti binary line with increasing Ti concentration, the volume fraction of the Mo phase and the interlamellar spacing of the Mo and TiC phases increase in the eutectic microstructure. At 1,800°C, the TiC phase in equilibrium with the Mo phase can contain more than 28 at% Mo and a Mo/TiC/Mo 2 C three-phase region exists at around Mo–15Ti–10C.

Applications of Electro-Osmotic Transport in the Processing of Textiles (1999)

We report development of a pilot process for the industrial rinsing of fabrics. This process combines hydraulic (pressure-driven) transport with electro-osmotic transport. It reduces the total amount of water required in certain rinsing operations by a factor of about five. Cotton exhibits an electro-osmotic transport coefficient of about 6 x 10{sup -9} m{sup 2}/s-V resulting from a partial ionization of hydroxyl groups on the cellulose polymer substrate. This process applies a field transverse to the fabric to effect the movement of water in the spaces between the 10 {micro}m cotton fibers which constitute the yam. The field strength is adjusted so that the induced electro-osmotic flux is comparable to a pressure-driven flux, which moves preferentially in the more open channels between the yams. For a fixed current density, solution conductivity and electro-osmotic transport vary inversely. The process is most practical for removal of liquids of relatively low conductivity (&lt;500 {micro}S/cm). For removal of solutions of conductivity greater than 1200 {micro}S/cm, the rate of electro-osmotic flow may be too low to benefit the rinsing process if current densities are restricted to practical levels of about 30 mA/cm{sup 2}. Electra-osmotic transport may have important applications in wet processing of extremely fine textiles, such as micro fiber fabrics. In addition to rinsing, electro-osmotic transport may also be used to speed the penetration of chemicals and dyestuffs that are applied to the surface of wet textiles.
Proximity Effect Correction for 1:1 X-Ray Mask Fabrication (1994)

This article describes the improvement of a self-consistent proximity effect correction to fabricate 1:1 X-ray masks. The present method has two features; the first is the change of sampling point from pattern edges to the center. This is effictive in saving on the calculation time, and it is theoretically shown that the deposited energy intensity at the edge is equal to that obtained with the conventional method. The other is to combine the pattern shape and additional dose modulations for finer patterns (≤4β f , β f is the forward scattering range of electrons) with the ordinary dose modulation method. The algorithm is verified by experiments and simulations, and is found to be effective in reproducing 0.1 µ m patterns with high accuracy.
A multisection ultra wideband directional coupler in multilayer broadside coupled stripline technology (2016)

In this paper, we present a multisection directional coupler providing a tight coupling of 10 dB with an equal ripple of 0.8 dB across the frequency range of 360 MHz to 5.8 GHz, which corresponds to a relative bandwidth of 177 %. To maximize coupling and reduce dispersion effects, the coupler uses broadside coupled striplines in a multilayer setup. The four ports of the coupler are connected via standard SMA-connectors through a stripline to microstrip transition that does not make use of vias. The design process is verified by EM simulations and measurements performed on a prototype.
Evaluation of neonatal pulmonary mechanics and energetics: A two factor least mean square analysis (1988)

Pulmonary mechanics, using a two factor least mean square analysis technique, were determined in 22 preterm neonates with respiratory failure. The respiratory system is modelled as a linear mechanical system. Concurrent signals of airflow and transpulmonary pressure were utilized to calculate values of dynamic lung compliance and pulmonary resistances; these determinations were made over the entire tidal volume range. In addition, values of resistive work of breathing, pulmonary time constants, scalar records of sequential breaths, pressure-volume and flow-volume relationships were available for data review and interpretation. The mean +/- SEM value of tidal volume was 7.4 +/- 0.6 ml/kg; dynamic lung compliance was 0.44 +/- 0.04 ml/cmH2O/kg; and the pulmonary resistance of the whole breath was 106 +/- 9.1 cmH2O/liter/s. The resistive work of breathing (hysteresis) was 41.8 +/- 5.9 gm.cm/kg. In correlating the measured values of pressure and flow to those predicted by the model, the mean value of the correlation coefficient for the least mean square analysis for all 22 studies was 0.995 +/- 0.001; the standard error of estimate of the predicted pressure was less than 4.4% of the range of pressures measured. Thereby, the model was considered to be appropriate for the neonatal respiratory system. In addition to the traditional procedures of evaluating the respiratory status of a sick neonate, bedside analysis of pulmonary mechanics provide graphical information, and quantitative data which should be useful in day-to-day pulmonary management.
Primes in the denominators of Igusa Class Polynomials (2003)

The purpose of this note is to suggest an analogue for genus 2 curves of part of Gross and Zagier's work on elliptic curves. Experimentally, for genus 2 curves with CM by a quartic CM field K, it appears that primes dividing the denominators of the discriminants of the Igusa class polynomials all have the property 1) that they are bounded by d, the absolute value of the discriminant of K, and 2) that they divide d-x^2, for some integer x whose square is less than d. A slightly stronger condition is given in Section 3. Such primes are primes of bad reduction for the genus 2 curve and primes of supersingular reduction for the Jacobian of the genus 2 curve.
Solid‐Phase Immunoassays (2005)

Solid-phase quantitative immunoassays are some of the most commonly used diagnostic tests for both soluble antigen composition and the assessment of cellular functions. These immunoassays (e.g., ELISA, ELISPOT) provide a highly sensitive means to measure the presence of antigen in defined and homogeneous samples such as purified proteins in buffer, as well as in undefined heterogenous biological samples such as cell lysates, tissue culture supernatants, blood, and other clinical samples. The sensitivity of these assays can enable (under optimal conditions) detection of protein concentrations in the picogram range. A recent modification of the basic ELISA immunoassay takes advantage of the phenomenon of grating-coupled surface plasmon resonance (GCSPR) to provide a label-free real-time variant of this solid-phase immunoassay. Using GCSPR, similar assessments of antigen-antibody interactions can be done with smaller sample sizes and in a microarray format that enables the simultaneous measurement of large numbers of antibody/antigen interactions on the same sensor chip. These measurements allow for a highly refined and sensitive determination of the effects that toxins can have on biological systems, and they can be applied to a variety of immune and non-immune protein, cell, and tissue evaluations.
mTOR signalling is an essential pathway for TGF-β1induced collagen synthesis (2015)

Idiopathic pulmonary fibrosis (IPF) is a form of interstitial lung disease of unknown cause. The pathogenesis is incompletely understood, but repetitive epithelial injury is thought to drive an aberrant wound healing response and promote fibrosis. Central to this process is Transforming Growth Factor-β (TGF-β<sub>1</sub>), a potent pro fibrotic cytokine, which promotes excessive extracellular matrix deposition. The aim of this study was to investigate the role of TGF-β<sub>1</sub> induced activation of the PI3K/mTOR pathway in mediating collagen deposition by human lung fibroblasts (HLFs). To examine the role of the PI3K/mTOR pathway in TGF-β<sub>1</sub> induced collagen synthesis, HLFs were treated with pharmacological titrations of potent pathway inhibitors. TGF-β<sub>1</sub> mediated <i>COL1A1</i> gene expression and extracellular type 1 collagen deposition were significantly inhibited by a dual PI3K/mTOR inhibitor. In contrast, selective PI3K inhibition had no significant inhibitory effect. Treatment with an ATP competitive mTOR inhibitor resulted in significantly reduced expression of <i>COL1A1</i> and type 1 collagen deposition in response to TGF-β<sub>1</sub>. mTOR interacts with accessory proteins to form 2 distinct complexes, mTORC1 and mTORC2. In contrast to an ATP competitive mTOR inhibitor which inhibits the activity of both mTOR complexes, treatment of HLFs with Rapamycin, an allosteric mTORC1 inhibitor, showed no inhibitory effect on TGF-β<sub>1</sub> induced collagen production. These data suggest PI3 kinase/mTOR signalling is an important component in TGF-β<sub>1</sub> induced collagen synthesis and that an mTORC2 dependent pathway mediates this functional response in primary HLFs. Targeting this pathway may represent a novel strategy for preventing disease progession in IPF.

Reactive oxygen species are the major antibacterials against Salmonella Typhimurium purine auxotrophs in the phagosome of RAW 264.7 cells (2008)

Intramacrophage survival appears to be a pathogenic trait common to Salmonellae and definition of the metabolic requirements of Salmonella within macrophages might provide opportunities for novel therapeutic interventions. We show that loss of PurG function in Salmonella enterica serovar Typhimurium SL1344 leads to death of the bacterium in RAW264.7 cells, which was due to unavailability of purine nucleotides but not thiamine in the phagosome of RAW264.7 cells. Phagosomal escape of purG mutant restored growth, suggesting that the phagosomal environment, but not the cytosol, is toxic to Salmonella purine auxotrophs. NADPH oxidase inhibition restored the growth of purG mutant in RAW264.7 cells, implying that the Salmonella-containing vacuole acquires reactive oxygen species (ROS) that are lethal to purine auxotrophs. Under purine limiting conditions, purG mutant was unable to repair the damage caused by hydrogen peroxide or UV irradiation, suggesting that ROS-mediated DNA damage may have been responsible for the attenuated phenotype of purG mutant in RAW264.7 cells and in mice. These studies highlight the possibility of utilizing the Salmonella purine nucleotide biosynthetic pathway as a prospective therapeutic target and also underline the importance of metabolic pathways in assembling a comprehensive understanding of the host-pathogen interactions inside phagocytic cells.
Review—Room-Temperature Ionic Liquids for Electrochemical Application with Special Focus on Gas Sensors (2019)

Room temperature ionic liquids (RTILs) are the most common electrolyte now a day, which is usually a molten salt comprised of cationic and anionic charge, generate a neutral species having high thermal stability and exceptional chemical property. Due to these unique properties, RTILs had been used for many applications as a solvent/electrolyte for decades. There are many RTILs, which possess good conductivity, as well as an optimum electrochemical window, which, is suitable for electrochemical sensor application. Among various electrochemical sensors available in the market, the electrochemical gas sensor is a popular device for environmental monitoring. The use of RTILs to the existing technology leads us to new era of sensing where we can able to address sensitivity, stability, robustness, and ability to do multiplex array along with the fundamental behind the electrochemical gas sensor. This paper is consisted of the electrical and electrochemical properties of some popular RTILs along with its application in electrochemical sensing, with a special focus on the electrochemical gas sensor. This review will help the general audience to fabricate the next-gen electrochemical sensor using RTILs.
Adsorption modeling and mechanistic insight of hazardous chromium on para toluene sulfonic acid immobilized-polyaniline@CNTs nanocomposites (2018)

The development of highly efficient adsorbents materials for the purification of wastewater has caught a considerable deal of attention these days. Conducting polymers functionalized adsorbents has become a favorable route for enhancing their adsorption capability due to their ease of synthesis at laboratory scale. In this study, functionalized multiwalled carbon nanotube (CNT)-polyaniline (Pani) composites were fabricated using an oxidation polymerization methodology and later doped with para toluene sulfonic acid (pTSA). The CNTs provided an adequate substrate for the adhesion of Pani as well as a large surface area due to its nano size, and pTSA provided additional functionality for the adsorption of differently charged moieties through strong or weak interactions. The as-synthesized p[email protected] nanocomposite was analyzed by the scanning electron microscopy, transmission electron microscopy for the morphological studies and the structural analysis were done by the X-ray diffraction, and X-ray photoelectron spectroscopy (XPS). The characterization results confirmed that the Pani was adhered to the CNTs as well as its successful functionalization with pTSA. The p[email protected] composite was then applied to the adsorptive removal of hexavalent chromium (Cr(VI)) and the composite showed higher adsorption for Cr(VI) than pTSA-CNT and pTSA-Pani, and the maximum removal level was detected at acidic pH. The analyses of the equilibrium isotherms and adsorption kinetics were performed to elucidate the adsorption mechanism. The XPS analysis indicated that Cr(VI) was strongly bounded to the adsorbent and it further indicated that the amine, imine, and hydroxyl functional groups were involved in the adsorption process. This study presents a new insight for the fabrication of highly functional polymer-carbonaceous nanocomposites for the scavenging of heavy metals from water bodies.
Is Data Privacy Always Good for Software Testing? (2010)

Database-centric applications (DCAs) are common in enterprise computing, and they use nontrivial databases. Testing of DCAs is increasingly outsourced to test centers in order to achieve lower cost and higher quality. When releasing proprietary DCAs, its databases should also be made available to test engineers, so that they can test using real data. Testing with real data is important, since fake data lacks many of the intricate semantic connections among the original data elements. However, different data privacy laws prevent organizations from sharing these data with test centers because databases contain sensitive information. Currently, testing is performed with fake data that often leads to worse code coverage and fewer uncovered bugs, thereby reducing the quality of DCAs and obliterating benefits of test outsourcing. We show that a popular data anonymization algorithm called k-anonymity seriously degrades test coverage of DCAs. We propose an approach that uses program analysis to guide selective application of k-anonymity. This approach helps protect sensitive data in databases while retaining testing efficacy. Our results show that for small values of k = 7, test coverage drops to less than 30% from the original coverage of more than 70%, thus making it difficult to achieve good quality when testing DCAs while applying data privacy.
The role of adenosine 1a receptor signaling on GFR early after the induction of sepsis (2017)

Sepsis and acute kidney injury (AKI) synergistically increase morbidity and mortality in the ICU. How sepsis reduces glomerular filtration rate (GFR) and causes AKI is poorly understood; one proposed mechanism includes tubuloglomerular feedback (TGF). When sodium reabsorption by the proximal tubules is reduced in normal animals, the macula densa senses increased luminal sodium chloride, and then adenosine-1a receptor (A1aR) signaling triggers tubuloglomerular feedback, reducing GFR through afferent arteriole vasoconstriction. We measured GFR and systemic hemodynamics early during cecal ligation and puncture-induced sepsis in wild-type and A1aR-knockout mice. A miniaturized fluorometer was attached to the back of each mouse and recorded the clearance of FITC-sinistrin via transcutaneous fluorescence to monitor GFR. Clinical organ injury markers and cytokines were measured and hemodynamics monitored using implantable transducer telemetry devices. In wild-type mice, GFR was stable within 1 h after surgery, declined by 43% in the next hour, and then fell to less than 10% of baseline after 2 h and 45 min. In contrast, in A1aR-knockout mice GFR was 37% below baseline immediately after surgery and then gradually declined over 4 h. A1aR-knockout mice had similar organ injury and inflammatory responses, albeit with lower heart rate. We conclude that transcutaneous fluorescence can accurately monitor GFR and detect changes rapidly during sepsis. Tubuloglomerular feedback plays a complex role in sepsis; initially, TGF helps maintain GFR in the 1st hour, and over the subsequent 3 h, TGF causes GFR to plummet. By 18 h, TGF has no cumulative effect on renal or extrarenal organ damage.
Grooved Pipe Joints on Shipboard Applications (2013)

Grooved piping has been used on shipboard applications since the early 1920’s, first in the United Kingdom than many other parts of the world. It gained rapid acceptance in the UK for its many advantages over flange connections. In the US it was used on many Merchant and Naval vessels constructed during World War II, partly for its speed of installation, but also for its less fussy tolerance requirements with regard to pipe length and joint alignment. It has since grown to become used worldwide in many types of vessels. This paper enumerates grooved pipe joints advantages and its technical underpinnings. Paper published with permission.
