Novel tunable acceptor doped BST thin films for high quality tunable microwave devices (2004)

"The materials properties of undoped and low concentration Mg doped Ba0:6Sr0:4TiO3 (BST) thin films are reported. The films were fabricatedon single crystal (100) MgO and Pt coated Si substrates via the metalorganic solution deposition (MOSD) technique using carboxylatealkoxideprecursors and post-deposition annealed at 800±C (film/MgO substrates) and 750±C (film/Pt-Si substrates). The dielectric propertieswere measured at 10 GHz using unpatterned/non-metallized films via a tuned coupled/split dielectric resonator system and at 100 kHz usingmetal-insulator-metal capacitors. The structure, microstructure, surface morphology and film/substrate compositional quality were analyzedand correlated to the films dielectric and insulating properties. The Mg doped BST films exhibited improved dielectric loss and insulatingcharacteristics compared to the undoped BST thin films. The improved dielectric properties, low leakage current, and good tunability of thelow level Mg doped BST thin films merits strong potential for utilization in microwave tunable devices."
A Review of the Fundamental Principles and Applications of Solution Blow Spinning (2016)

Solution blow spinning (SBS) is a technique that can be used to deposit fibers in situ at low cost for a variety of applications, which include biomedical materials and flexible electronics. This review is intended to provide an overview of the basic principles and applications of SBS. We first describe a method for creating a spinnable polymer solution and stable polymer solution jet by manipulating parameters such as polymer concentration and gas pressure. This method is based on fundamental insights, theoretical models, and empirical studies. We then discuss the unique bundled morphology and mechanical properties of fiber mats produced by SBS, and how they compare with electrospun fiber mats. Applications of SBS in biomedical engineering are highlighted, showing enhanced cell infiltration and proliferation versus electrospun fiber scaffolds and in situ deposition of biodegradable polymers. We also discuss the impact of SBS in applications involving textiles and electronics, including ceramic fibers and conductive composite materials. Strategies for future research are presented that take advantage of direct and rapid polymer deposition via cost-effective methods.
Induction of heme oxygenase-1 attenuates lipopolysaccharide-induced cyclooxygenase-2 expression in mouse brain endothelial cells (2010)

We show here a novel inhibition of HO-1 on LPS-induced COX-2/PGE2 production in bEnd.3. Our results reinforce the emerging role of cerebral endothelium-derived HO-1 as a protector against cerebral vascular inflammation triggered by bacterial infection.

Beyond Passive Audiobook: How Digital Audiobooks Get Interactive (2007)

Although the audiobook market is growing at an exceptional speed, an audiobook is limited to passive listeners. In this paper we propose a novel approach to transform a passive listener into a story director. By introducing interactivity into digital audiobook, a user can interact with the storyline and the story develops according to user choices. We propose an architecture that produces interactive audiobooks in a transparent and secure way. Transparency is achieved by using the AAC format for the audio stream, the MPEG7-DDL for the audio description and the ISO Base Media File Format for the audiobook file format; security is achieved with a mechanism that protects the digital content from illegal usage and avoids any possible content malicious alteration. The simplicity of our approach, along with the growing usage of portable devices, may find new markets for the audiobook in the educational and entertainment worlds.
Simple and unambiguous method for identifying urinary acylcarnitines using gas chromatography-mass spectrometry (1990)

Several inherited metabolic disorders, particularly the organic acidurias and acidemias, are often characterised by excretion of acylcarnitines, especially octanoylcarnitine, in the urine. Clinical investigation of such serious disorders ideally requires a rapid, simple and selective method for determining acylcarnitines in urine. Initial results are given here of a method that may approach this ideal. The procedure involves chemical derivatisation, in which the zwitterionic acylcarnitines are cyclised to volatile lactones, and analysis by gas chromatography and gas chromatography--mass spectrometry. Preparation of urine samples by ion-exchange purification and an illustrative application of the proposed method to a clinical sample are also outlined.
Objective evaluation of handling quality (2002)

Vehicle dynamics quality is generally evaluated by two approaches: subjective evaluations using driver ratings and objective measurements of vehicle dynamics characteristics. In both approaches it is important to define features of vehicle dynamics in order to cover all aspects, but without redundancy. For this reason, the first part of the paper tries to summarize the principal qualities and to how they might be organized. In the second part, the paper describes those procedures that can be used to obtain objective quality indices. First of all, criteria used in subjective testing (questionnaire design, jury selection, etc.) are described. Then it is determined which manoeuvres can be performed, and which physical quantities should be considered, in order to obtain objective parameters that correlate with subjective evaluation. After this, the paper briefly describes the statistical technique used to identify which measured variables best correlate with vehicle dynamics qualities. In the third part, the paper contains a practical application of the objective index identification procedure regarding handling quality. Some examples are given about how these indices are used in different phases of a new car development, from target setting to target deployment, and in target achievement and verification during final tuning.
Construction and High Performance of a Novel Modified Boron-Doped Diamond Film Electrode Endowed with Superior Electrocatalysis (2010)

A modified boron-doped diamond (BDD) electrode was prepared by evenly assembling Sb-doped SnO2 nanoparticles on the BDD surface, which possesses excellent electrocatalytic performance and is more suitable to degrade the pollutants. The growth of Sb-doped SnO2−NPs was controlled using micelles of the block copolymer surfactant and homogeneous precipitation approaches. SEM and HRTEM confirmed that BDD still can be fully exposed after modification of Sb-doped SnO2−NPs. The prepared Sb-doped SnO2−NPs/BDD electrode maintained high oxygen evolution potential (2.3 V vs SCE); meanwhile, its conductivity is greatly improved when the resistance decreases to 1.2 from 60.8 kΩ and the reaction activation energy also reduces from 8.02 to 4.93 kJ mol−1, owing to the excellent electrocatalytic performance. Moreover, Sb-doped SnO2−NPs/BDD has higher oxidation ability. The reaction rate constant of 2,4-D on the Sb-doped SnO2−NPs/BDD is 2 times and mineralization current efficiency at 30 min on the Sb-doped SnO2−NPs/BDD is 1.6 times that on the BDD. The time for complete removal of the total organic carbon (TOC) is 240 min on the Sb-doped SnO2−NPs/BDD electrode, while it is beyond 360 min on the BDD. Energy consumption on the BDD is 1.3 times that on the Sb-doped SnO2−NPs/BDD for the TOC total removal. The generation and further oxidation of the intermediates further approved the high efficiency of the Sb-doped SnO2−NPs/BDD.

Synthetic α-Subunit Peptides Stimulate Testosterone Production<i>in Vitro</i>by Rat Leydig Cells* (1990)

The glycoprotein hormones (LH, hCG, FSH, and TSH) have a common 92-amino acid alpha-subunit which is noncovalently linked to a hormone-specific beta-subunit. Synthetic peptides of the alpha-subunit have been shown to inhibit binding of [125I]iodo-hCG to rat ovarian membrane and [125I]iodo-TSH to human thyroid membrane preparations. Synthetic overlapping peptides of the alpha-subunit of hCG were prepared by solid phase techniques and tested in a standard in vitro rat Leydig cell bioassay. Three regions in the alpha-subunit (alpha 1-15, alpha 30-45, and alpha 71-85) were found to stimulate testosterone production. All three regions correlate with inhibition of hCG binding to ovarian receptors, but subtle differences exist between the binding sites and effector sites. These data indicate that the glycoprotein alpha-subunit has intrinsic bioactivity.
Colonic interposition for esophageal substitution. (1983)

Sufficient information has now accumulated to permit a better definition of the role of colonic interposition for substitution of the esophagus. For children and young adults with a long life expectancy, the interposed colon provides a well-functioning and durable conduit. When the stomach cannot be used, the colon is the best alternative in most patients. Necrosis of the colon remains the most frequent fatal complication; leakage and stenosis of the proximal anastomosis remain problems. Although results of the usual radiologic examinations with barium show that the colon empties by gravity, manometric results may demonstrate progressive peristalsis, particularly in response to stimulus from a bolus of dilute acid.
Characterization of Three Maize Bacterial Artificial Chromosome Libraries toward Anchoring of the Physical Map to the Genetic Map Using High-Density Bacterial Artificial Chromosome Filter Hybridization (2002)

Three maize (Zea mays) bacterial artificial chromosome (BAC) libraries were constructed from inbred line B73. High-density filter sets from all three libraries, made using different restriction enzymes (HindIII, EcoRI, and MboI, respectively), were evaluated with a set of complex probes including the 185-bp knob repeat, ribosomal DNA, two telomere-associated repeat sequences, four centromere repeats, the mitochondrial genome, a multifragment chloroplast DNA probe, and bacteriophage lambda. The results indicate that the libraries are of high quality with low contamination by organellar and lambda-sequences. The use of libraries from multiple enzymes increased the chance of recovering each region of the genome. Ninety maize restriction fragment-length polymorphism core markers were hybridized to filters of the HindIII library, representing 6x coverage of the genome, to initiate development of a framework for anchoring BAC contigs to the intermated B73 x Mo17 genetic map and to mark the bin boundaries on the physical map. All of the clones used as hybridization probes detected at least three BACs. Twenty-two single-copy number core markers identified an average of 7.4 +/- 3.3 positive clones, consistent with the expectation of six clones. This information is integrated into fingerprinting data generated by the Arizona Genomics Institute to assemble the BAC contigs using fingerprint contig and contributed to the process of physical map construction.
The insulin receptor tyrosyl kinase phosphorylates holomeric forms of the guanine nucleotide regulatory proteins G<sub>i</sub> and G<sub>o</sub> (1987)

An affinity purified human insulin receptor preparation was shown to phosphorylate the alpha- and beta-subunits of the guanine nucleotide-regulatory proteins Gi and Go, derived from bovine brain. The presence of insulin stimulated the rate of their phosphorylation some 2-fold. The presence of Gi and Go did not affect the degree of autophosphorylation of the beta-subunit of the insulin receptor. Under conditions known to cause the dissociation of Gi and Go into their constituent subunits then phosphorylation of Gi and Go by the insulin receptor was abolished. The alpha-subunits of Gi and Go could be selectively phosphorylated by the insulin receptor tyrosyl kinase using appropriate concentrations of Mg2+ and GTP-gamma-S.
(Invited) Selective Area Growth of InP on On-Axis Si(001) Substrates with Low Antiphase Boundary Formation (2011)

We discuss the selective epitaxial growth of InP on patterned Si (001) substrates with Shallow Trench Isolation using a thin Ge buffer to facilitate InP nucleation. The main focus is the defect formation mechanism during epitaxial growth and to develop solutions to reduce defect density so that device-quality III-V virtual substrates can be realized on large-scale Si substrates. We compare the InP growth on on-axis and off-axis Si substrates. In the case of off-axis wafers, the formation of stacking faults / twins cannot be avoided, at least not at one of the four STI side-walls. The formation of antiphase domain boundaries is reduced (but not yet completely eliminated) by engineering the local Ge surface profile. Further, the high density of Ge surface steps promotes step-flow growth mode instead of 3D growth during the growth of the InP seed layer. Finally, high aspect ratios (>2) allow to confine threading dislocations in the bottom of the trench.
Processor array for factorization of unstructured sparse matrices (1982)

A data structure and processor array architecture are proposed for the solution of large, sparse systems of linear equations of the type generated by simulation of LSI circuits. This array performs a parallel Lu factorization of an unstructured n*n sparse matrix using significantly less than n processor stages. The design decouples the required number of processor stages from n while maintaining a high rate of computation. 6 references.
Molecular docking based screening of novel designed chalcone series of compounds for their anti-cancer activity targeting EGFR kinase domain (2015)

Epidermal growth factor receptors (EGFR) are critical for the growth of many tumors and expressed at high levels in about one third of epithelial cancers. Hence, blockade of the binding sites for EGFR has been hypothesized as an effective anti-cancer therapy. Chalcone derivative compounds have been shown to be highly effective anti-cancer agents, however there are still so many novel derivatives possible, one of which might get us the best targeted EGFR inhibitor. In this effort directed towards the discovery of novel, potent anti-tumor agents for the treatment of cancer, in the present study a library of novel chalcone series of compounds has been designed and evaluated for their anti-cancer activity targeting EGFR kinase domain using various computational approaches. Among the twenty five novel designed chalcone series of compounds, all of them have found to be successfully docking inside the active binding domain of EGFR receptor target with a binding energy in a range of -6.10 to -9.25 Kcal/mol with predicted IC50 value range of 33.50 micor molar to 164.66 nano molar respectively. On the other hand, calculated 2DQSAR molecular descriptor properties of the compounds showed promising ADME parameters and found to be well in compliance with Lipinski׳s rule of five. Among all the twenty five compounds tested, compound 21 ((2E)-3-(anthracen-9-yl)-1-phenylprop-2-2n-1- one) was found to be the best lead like molecule with a binding energy of -9.25 kcal/mol with predicted IC50 value of 164.66 nano molar. Conclusively, novel designed compound 21 of the present study have shown promising anti-cancer potential worth considering for further evaluations.
A Novel Approach for Rain Removal from Videos Using Low-Rank Recovery (2014)

We propose a novel approach for rain/snow removal from videos using low-rank recovery. Rain/snowdistorted video frames are treated as a distorted 3D signal. The main goal is to separate the distortion, which is the rain or snow additive signal, from the original rain-free signal. Inter-frame information is exploited to put the problem in a convex optimization form. Then, the exact augmented Lagrangian multipliers (EALM) method is used to solve the model for the low-rank terms, which represent the rain/snow-free frames. The proposed approach has several advantages over the existing approaches. It is model-independent, i.e. it does not require shape, appearance, or speed models. Also, it does not need prior information about the acquisition environment. Three different sets of data were used for evaluation: synthetic data for simulation experiments to provide quantitative results, real static videos, and real dynamic videos. The evaluation results proved the effectiveness of the proposed approach when compared to the existing approaches.
Optimization analysis for recycle-oriented manufacturing systems (1995)

Recycling has been recently recognized as one of effective tools for solving environmental problems. In this respect present and future manufacturing systems should take the recycling of materials used into consideration. This paper points out the issues contained in such a recycle-oriented manufacturing system, then the basic parts-flow in the product's life cycle is clarified by taking account of re-use and re-production of the parts contained in the product. A model is constructed to maximize two measures of performance—total profit and recycling rate. This is solved by goal programming. Finally, a numerical example is used to demonstrate the effectiveness of the model proposed.
Acousto-optic imaging of absorbing structures using multiply scattered light (1996)

Summary form only given. The relatively weak attenuation of diffuse light as compared to ballistic light makes its use attractive for medical and biological imaging. A number of techniques have been developed to exploit diffuse light in imaging. These include imaging with diffuse photon density waves and the reconstruction from time-resolved transmission measurements. We have attempted to utilize acousto-optic modulation of diffuse light for imaging. We point out the consequences of the incoherent nature of the signal for tomographic imaging and demonstrate imaging of absorbing structures embedded within a strongly scattering medium with a resolution of approximately 2 mm. The sample that is excited by an ultrasound beam is illuminated by a laser beam.
Required source distribution for interferometry of waves and diffusive fields (2009)

The Green's function that describes wave propagation between two receivers can be reconstructed by cross-correlation provided that the receivers are surrounded by sources on a closed surface. This technique is referred to as 'interferometry' in exploration seismology. The same technique for Green's function extraction can be applied to the solution of the diffusion equation if there are sources throughout in the volume. In practice, we have only a finite number of active sources. The issues of the required source distribution is investigated, as is the feasibility of reconstructing the Green's function of the diffusion equation using a limited number of sources within a finite volume. We study these questions for homogeneous and heterogeneous media for wave propagation and homogeneous media for diffusion using numerical simulations. These simulations show that for the used model, the angular distribution of sources is critical in wave problems in homogeneous media. In heterogeneous media, the position and size of the heterogeneous area with respect to the sources determine the required source distribution. For diffusion, the sensitivity to the sources decays from the midpoint between the two receivers. The required width of the source distribution decreases with frequency, with the result that the required source distribution for early- and late-time reconstruction is different. The derived source distribution criterion for diffusion suggests that the cross-correlation-based interferometry is difficult to apply in field condition.
Antibody and T-Cell Receptors (1988)

A VERTEBRATE is an attractive culture medium for viruses, bacteria, fungi, and metazoan parasites. It is therefore understandable that vertebrates have had to develop a body defense mechanism directed toward these pathogens for their emergence and survival. This defense mechanism is the See also pp 1834 and 1837. immune system. The crucial event in mounting an immune response is the recognition of chemical markers that are present on infectious organisms and foreign bodies. The molecules entrusted to this task are the B-cell-synthesized antibodies and the antigen-specific T-cell receptors (TCRs). Antigens are numerous and structurally diverse. The fact that the body can produce antibodies against many artificially made chemicals and can discriminate among them attests to the vastness of the antigenic world. The antigen-binding specificity of an antibody or a TCR is determined by the amino acid sequence of the polypeptide chains that compose these proteins. The enormous diversity of antigens,
Electrochemical and Electrostatic Energy Storage and Management Systems for Electric Drive Vehicles: State-of-the-Art Review and Future Trends (2016)

Recently, increased emissions regulations and a push for less dependence on fossil fuels are factors that have enticed a growth in the market share of alternative energy vehicles. Readily available energy storage systems (ESSs) pose a challenge for the mass market penetration of hybrid electric vehicles (HEVs), plug-in HEVs, and EVs. This is mainly due to the high cost of ESS available today. However, tremendous research efforts are going into reducing the cost of these storage devices, increasing their lifespan, and improving their energy density. This paper aims to give an overview of the current state of readily available battery and ultracapacitor (UC) technologies as well as a look ahead toward promising advanced battery chemistries and next generation ESS. Energy management systems and various battery balancing configurations are discussed in addition to battery state/parameter estimation and protection mechanisms. Finally, hybrid ESSs (HESS) are reviewed as a mitigation strategy to the shortcomings of traditional battery and UC technologies. Consideration is given to the combination of advanced battery chemistries with UCs to portray HESS performance, which can meet and exceed the performance of current ESS technologies.
