SiC-Based Z-Source Resonant Converter With Constant Frequency and Load Regulation for EV Wireless Charger (2016)

Traditional load regulation methods for a resonant converter mainly rely on frequency modulation. It is always a tradeoff between the design of the resonant network and the range of load. Especially for wireless power transfer (WPT) systems, the resonant network usually has a high quality factor. Small variation on frequency leads to huge drop in gain and efficiency. Due to this problem, many WPT systems are unregulated and they need one or two more front-end stages to regulate the dc bus voltage and perform power factor correction (PFC). In order to lower the cost and complexity of two- or three-stages structure, a single-stage solution with a silicon carbide (SiC) based Z-source resonant converter (ZSRC) was recently proposed. The Z-source network provides high reliability as being immune to shoot-through problems. Additionally, a ZSRC can boost the dc bus voltage while the traditional voltage-source inverter can only produce a lower voltage. However, the load regulation of this new topology has not been addressed. Two effective load regulation methods with constant frequency are presented for this SiC-based ZSRC specifically. Operation principle of the two load regulation methods are described in this paper. Experimental results based on a 200-W scale-down prototype with a full-bridge series resonant dc-dc converter are presented to illustrate the mechanism of these two methods.
CDMA forward link waterfilling power control (2002)

Waterfilling is used here to mean transmitting delay-tolerant data users mostly when the channel is good. First, a result is given which yields a simple interpretation of an algorithm which shows how it provides a throughput levelling and an appealing tradeoff between throughput and fairness. Then, an extension is given of the algorithm from transmitting a single user at a time to transmitting more than one user at a time. Finally, a comparison with more traditional power control is given. The results indicate promising improvement.
Identifying essential proteins based on protein domains in protein-protein interaction networks (2013)

Prediction of essential proteins which are crucial to an organism survival is important for disease analysis and drug design, as well as the understanding of cellular life. The majority of prediction methods infer the possibility of proteins to be essential by using the network topology. However, these methods are limited to the complementation of available protein-protein interaction (PPI) data and depend on the network accuracy. To overcome these limitation, some computational methods have been proposed while seldom of them solve this problem by taking consideration of protein domains. In this work, we firstly analyze the correlation between the essentiality of proteins and their domain features based on data of 13 species. We find that the proteins containing more protein domain types which rarely occur in other proteins tend to be essential. Accordingly we propose a new prediction method, named UDoNC, by combining the domain features of proteins with their topological properties in PPI network. In UDoNC, the essentiality of proteins is decided by the number and the frequency of their protein domain types, as well as the essentiality of their adjacent edges measured by edge clustering coefficient. The experimental results on S. cerevisiae data show that UDoNC outperforms other existing methods in terms of area under the curve (AUC).

Lubricity Problems and Solutions for a Methanol Fueled Gas Turbine (2000)

Abstract The Liquid Phase Methanol (LPMEOH™) process, which was developed by Air Products and Chemicals Inc. and sponsored by the United States Department of Energy, uses a slurry bubble column reactor to convert synthesis gas to methanol. In 1998, LPMOH™ “as produced” (about 98% purity) was used at West Virginia University to fuel a small (235 Hp) gas turbine. The objective was to demonstrate the viability of LPMEOH™ as a gas turbine fuel, identify and operational problems and obtain exhaust gas emissions samples using the WVU Mobile Emissions Laboratory. During these tests, the fuel system gear pump and rpm controller failed due to the lack of lubricity of the methanol fuel. To remedy this problem, a pint (over an order of magnitude larger than the recommended amount) of a commercially available fuel additive was dissolved in half a barrel of methanol, and the fuel controller/pump was replaced. The next series of runs produced a similar failure. This prompted the WVU team to search for a suitable methanol additive, which can provide lubricity equal or better than that of jet fuel. To minimize the amount and thus cost of such an additive, it was essential to accurately measure lubricity of methanol/additive solutions, at various concentration levels. Conventional lubricity measuring tests are based on measuring wear. When used with methanol, the data were erratic due to a changing wear pattern. To get repeatable steady data, a new lubricity test apparatus was developed, based on comparing friction coefficients, at a typical bearing design load. After many modifications this apparatus provided satisfactory and consistent results. A few percent castor oil or less than one percent of Two Cycle Blue, a racing fuel additive, produced a methanol lubricity in excess of that of jet fuel.
Primary Pulmonary Hypertension (1984)

PRIMARY pulmonary hypertension (PPH) is a term currently used to define the presence of pulmonary hypertension of unexplained etiology. Although the disease entity was recognized in the early 1900s, it was not until 1951 that Dresdale coined the term<i>primary pulmonary hypertension</i>, which is used today. The purpose of this update is to review the salient features of PPH and highlight some future directions. <h3>DIAGNOSIS</h3> To make the diagnosis of PPH, certain positive and negative clinical criteria must be met. It cannot be overemphasized that PPH is a diagnosis of exclusion and is only as reliable as the extent to which secondary causes of pulmonary hypertension have been ruled out. The most common secondary causes of pulmonary hypertension and the methods by which they can be diagnosed or excluded are listed in Table 1. The emphasis on making an accurate diagnosis is underscored because therapies for secondary forms of pulmonary
Value of Haemonchus longistipes Purified Antigens in Diagnosis of Gastro-intestinal Nematodes Infection in Camels (2007)

Fractionated Haemonchus longistipes crude antigen revealed 7 protein fractions at molecular weights of 93, 74, 67, 56, 32, 26 and 16 kDa. The bands at 56, 32 and 26 kDa reacted specifically with H. longistipes hyperimmune sera prepared in rabbit (1:100 dilution) using EITB technique. The eluted concentrated fractions as well as crude worm antigens were used in diagnosis of natural infection of Gastro-Intestinal Nematodes (GIN) only or associated with other parasites in camels using ELISA technique. H. longistipes crude antigen and fraction of 26 kDa induced high sensitivity in diagnosis of infection in animals harboring GIN only (sensitivity was 95-100%), while it was 85.0-93.3% with 32 kDa fraction and 55.5-73.3% with that of 56 kDa using ELISA technique. The two H. longistipes eluted protein fractions of 26 and 32 kDa showed higher sensitivity than their crude antigens in diagnosis of GIN infection mixed with other parasites. While, Protein bands of 26 kDa appeared more sensitive than the other protein bands in detection of anti- H. longistipes antibodies at higher serum dilution. With special superiority for fraction of 26 kDa, in comparison with the other antigens, sharp specificity or sensitivity in diagnosis, could not be achieved in this study especially in case of mixed infection with other parasites, where these animals might be immune-compromised.
Copolymerization of Ethylene and Methyl Acrylate by Cationic Palladium Catalysts That Contain Phosphine-Diethyl Phosphonate Ancillary Ligands (2014)

A series of benzo-linked phosphine-diethyl phosphonate (P-PO) and phosphine-bis(diethyl phosphonate) (P-(PO)2) ligands and the corresponding (P-PO)PdMe(2,6-lutidine)+ and (P-(PO)2)PdMe(2,6-lutidine)+ complexes were synthesized. Cationic (P-PO)PdMe(2,6-lutidine)+ complexes are active for ethylene oligomerization/polymerization, with activities of 2 kg mol–1 h–1 for {κ2-1-PiPr2-2-P(O)(OEt)2-5-Me-Ph}PdMe(2,6-lutidine)+ (3c), 125 kg mol–1 h–1 for {κ2-1-PPh2-2-P(O)(OEt)2-5-Me-Ph}PdMe(2,6-lutidine)+ (3a), and 1470 kg mol–1 h–1 for {κ2-1-P(2-OMe-Ph)2-2-P(O)(OEt)2-Ph}PdMe(2,6-lutidine)+ (3b). The polyethylene is highly linear, with over 80% terminal unsaturation and low (230–1890 Da) molecular weight in all cases. 3b copolymerizes ethylene with methyl acrylate, exhibiting highly selective (95%) in-chain (rather than chain-end) acrylate incorporation. The P-(PO)2 catalyst {κ2-1-P(4-tBu-Ph)(2-P(O)(OEt)2-5-Me-Ph)-2-P(O)(OEt)2-5-Me-Ph}PdMe(2,6-lutidine)+ (3d) is more active for ethylene homopolymerization (2640 kg mol–1 h–1), yielding linear, low-molecular-weight polymer (1280–1430 Da) with predominantly internal olefin placement. In ethylene/methyl acrylate copolymerization, 3d incorporates 2.6 mol % methyl acrylate, 60% of which is in-chain. Both 3b and 3d catalyze ethylene/acrylic acid copolymerization, albeit with low (<10 kg mol–1 h–1) activities and acrylic acid incorporation up to 1.1 mol %.
Benchmarking block ciphers for wireless sensor networks (2005)

The energy efficiency requirement of wireless sensor networks (WSN) is especially high because the sensor nodes are meant to operate without human intervention for a long period of time with little energy supply. Besides, available storage is scarce due to their small physical size. Therefore choosing the most storage- and energy-efficient block cipher for WSN is important. However to our knowledge so far no systematic work has been conducted in this area. We have identified the candidates of block ciphers suitable for WSN based on existing literature and authoritative recommendations. We have benchmarked these candidates and based on this benchmark, we have selected the suitable ciphers for WSN, namely Rijndael for high security and energy efficiency requirements; but MISTY1 for good storage and energy efficiency. In terms of operation mode, we recommend output feedback mode for static networks, but counter mode for dynamic networks.
Origin of protons accelerated by an intense laser and the dependence of their energy on the plasma density (2003)

We study the high-energy (1-4 MeV) proton production from a slab plasma irradiated by a ultrashort high-power laser. In our 2.5-dimensional particle-in-cell simulations, a p-polarized laser beam of 1.6 x 10(19) W/cm(2), 300 fs, lambda(L)=1.053 microm, illuminates a slab plasma normally; the slab plasma consists of a hydrogen plasma, and the target plasma thickness and the laser spot size are 2.5lambda(L) and 5lambda(L), respectively. The simulation results show that an emitted proton energy depends on the slab plasma density, and three kinds of high-energy proton beams are generated at the target plasma surfaces: one kind of the proton beams is produced at the laser-illuminated target surface and accelerated to the same laser-incident side. The second is generated at the target surface opposite to the laser-illuminated target surface and is accelerated outward on the same side. The third is generated at the laser-illuminated target surface and accelerated to the opposite side while passing through the target plasma. The simulations also show a mechanism of proton accelerations. In an overdense plasma, laser energy goes to energies of hot electrons and magnetic fields in part; the electrons oscillate around the slab plasma so that a static electric field is generated and consequently protons are extracted. The magnetic field generated in the slab plasma exists longer and heats up the plasma electrons to sustain the static electric field even after the laser termination.
EXPERIMENTAL VACUUM SPRAY DRYING OF PROBIOTIC FOODS INCLUDED WITH LACTIC ACID BACTERIA (2009)

ABSTRACT This research aims to develop a vacuum spray dryer (VSD) that performs spray drying in a vacuumed drying tower at a lower temperature than the conventional spray drying. The VSD operational drying temperatures for the probiotic foods containing lactic acid bacteria were determined by the relationships between the temperature and the vapor pressure, and were correlated by Clapeyron's equation. The drying of the fermented milk starter at 35C drying tower was experimentally possible; however, powder from the lactic fermenting beverage was not obtained even at 50C, which resulted from the lower glass transition temperature of the material. Compared with ATP concentration of the fermented milk starter before and after the VSD drying, the lower the drying temperature, the higher the microbial activity is retained. The ATP ratio as 30% of the raw materials shows the high feasibility of VSD for dairy processing. PRACTICAL APPLICATIONS During the spray drying of liquid or slurry food, the heat-sensitive functional ingredients such as vitamin, enzyme or bacteria are usually degraded or lost because of the contact with hot air between 120 and 180C. Markets need food powder that involves a lot of functional materials and a long shelf life for the expansion of healthy food. The experimental vacuum spray dryer (VSD) showed a potential to dry probiotic foods involving lactic acid bacteria without their inactivation. Although the lactic acid bacteria contained in the powder at 35C–VSD was 30% of the raw material, it is more economical than using the liquid type fermented milk starter. With some mechanical or operational modifications for the high moisture content and low recovery ratio of the powder, VSD is applicable for dairy processing factories.
DNA aptamer assemblies as fibroblast growth factor mimics and their application in stem cell culture (2019)

Replacing expensive and thermally unstable growth factors with synthetic alternatives has been an important issue in stem cell-based regenerative medicines. Here we developed DNA aptamer-assemblies that act as functional mimics of basic fibroblast growth factor (bFGF), one of the essential factors for stem cell culture. The most potent aptamer assembly named TD0, composed solely of 76-mer single-stranded DNA, could support the self-renewal and pluripotency of induced pluripotent stem cells (iPSCs). This work presents the first application of DNA aptamer in the maintenance of iPSCs.
Integration of object-oriented software components for distributed application software development (2003)

The process of component integration for distributed application software development requires identifying the candidate components and performing compatibility checks based on the functional as well as non-functional requirements of the target application software. Since these requirements vary, it is important that distributed components themselves provide a set of specific services to facilitate component integration. In this paper, an approach to component integration for distributed application software is given. An object-oriented distributed component framework and a distributed connector model are presented to facilitate component integration.
Optimization of the average-dispersion range for long-haul dispersion-managed soliton systems (2000)

We consider limitations on unfiltered transmission of dispersion-managed solitons, arising from the Gordon-Haus jitter, adjacent pulse interaction, and signal-to-noise degradation. We maximize the range of allowed values of average dispersion, thereby providing the first step in optimization of dispersion maps for wavelength-division-multiplexed lightwave systems. As specific examples, we consider dispersion maps made of several different types of optical fiber and study their performance for transmission of 10-40 Gb/s channels over distances in the range from 3000 km to 10000 km.

Phorbol esters induce differentiation in human malignant T lymphoblasts (1980)

At nanomolar concentrations, phorbol ester, a class of potent tumor promoters, can promote differentiation in the human malignant T-lymphoblastic cell line MOLT-3. The optimal dose for induction, as measured by the increase of the number of cells containing sheep erythrocyte receptors (E-rosette assay), is between 8 and 16 nM 12-O-tetradecanoylphorbol 13-acetate (TPA), although there were significant increases of E-rosette-positive (E(+)) cells at concentrations as low as 1.6 nM TPA. The induction was linear for 4 days, then it reached a plateau. This induction was independent of the cell densities of the cultures, and the viability of the E(+) cells remained high (95-100%) even after 10 days of culture in the presence of the tumor promoters. The E(+) cells, when measured with the more stable 2-aminoethylisothiouronium bromide E-rosette assay, indicated that virtually all (75-95%) of the MOLT-3 cells became E(+) by 4 days in culture. This induction by TPA was also accompanied by a dramatic drop in the plating efficiencies and a reduction in DNA synthesis. Examination of phorbol and other phrobol esters indicated that the ability to induce these cells correlated well with the tumor-promoting activities of these compounds, because only TPA and to a lesser extent phorbol 12,13,-dibenzoate induced E(+) cells, while phorbol and 4alpha-phorbol 12,13-didecanoate had no effect. Studies of MOLT-3 cells depleted of E(+) cells indicated that the induction of E(+) cells cannot be explained solely on the basis of enrichment or stimulation of the background E(+) cells in MOLT-3 cultures. Finally, we have shown that TPA also affected another differentiation marker, the loss of the enzyme terminal deoxyribonucleotidyl transferase. Terminal transferase activities and percentages of terminal-transferase-positive cells in these cultures were reduced to as low as 1/10th in 4 days in the presence of 16 nM TPA.
Discovery of <i>N</i>-(4-Methoxyphenyl)-<i>N</i>,2-dimethylquinazolin-4-amine, a Potent Apoptosis Inducer and Efficacious Anticancer Agent with High Blood Brain Barrier Penetration (2009)

As a continuation of our structure-activity relationship (SAR) studies on 4-anilinoquinazolines as potent apoptosis inducers and to identify anticancer development candidates, we explored the replacement of the 2-Cl group in our lead compound 2-chloro-N-(4-methoxyphenyl)-N-methylquinazolin-4-amine (6b, EP128265, MPI-0441138) by other functional groups. This SAR study and lead optimization resulted in the identification of N-(4-methoxyphenyl)-N,2-dimethylquinazolin-4-amine (6h, EP128495, MPC-6827) as an anticancer clinical candidate. Compound 6h was found to be a potent apoptosis inducer with EC(50) of 2 nM in our cell-based apoptosis induction assay. It also has excellent blood brain barrier penetration, and is highly efficacious in human MX-1 breast and other mouse xenograft cancer models.
Rheological and molecular properties of organic peroxide induced long chain branching of recycled and virgin high density polyethylene resin (2009)

Abstract Commercial blow molding grade recycled high density polyethylene (R‐HDPE) and blow molding grade virgin high density polyethylene (V‐HDPE) were reactively extruded with various compositions (0.00–0.15% wt/wt) of different peroxides in a twin screw extruder. The aim was to produce the extended chain mechanism of a blow molding grade HDPE photopolymer—a polymer resin comprising a significant part of the post consumer recycled plastic stream in Australia. In shear rheological tests, the modified material exhibited an increase in viscoelastic properties and complex viscosity compared to unmodified counterparts. Higher extent of viscoelastic properties enhancement was observed with 1, 3 1, 4 BIS (tert‐butylperoxyisopropyl) Benzene (OP2). This could be attributed to the higher degree of branching. The weight average molecular weight of the all modified materials and its molecular weight distribution (MWD) widened with peroxide modification. These results also support that formation of branching dominates the modification process at molecular level. Increase in branching index ( g ′) with increase in peroxide composition also confirmed higher degree of branching. POLYM. ENG. SCI., 2009. © 2009 Society of Plastics Engineers
LVII.—The action of ozone on cellulose (1912)

Flow cytometric monitoring of glutathione content and anthracycline retention in tumor cells (1991)

We have used an enzymatic (spectro-photometric) and a flow cytometric (GSH-MBCL) method to compare the glutathione (GSH) content of doxorubicin sensitive (P388) and resistant (P388/R-84) murine leukemic and human lung cancer cells. The flow cytometric analysis revealed that GSH-MBCL conjugate formation was dependent on glutathione-S-transferase (GST) activity. The human solid tumor cell lines exhibited extensive heterogeneity, high GSH content, and GST activity. In contrast to the enzymatic method, the flow cytometric method did not accurately reflect the 95% reduction in GSH content of cells treated for 24 h with 100 microM BSO. Possible reaction of MBCL with other sulfhydryl groups (other than GSH) in BSO-treated cells may be responsible for this discordance. We have also shown the feasibility of using dual parameter flow cytometry to monitor cellular anthracycline (daunorubicin) retention and GSH-MBCL conjugate fluorescence in human tumor cells. These two parameters, which measure drug retention and cellular detoxification, are believed to be the important determinants of chemoresistance in tumor cells.
