Trust in Education Professionals (2008)

This study extends the research on issues of trust in family—professional relationships by more fully examining, within a qualitative research design, the nature of trust between parents of children with disabilities and school personnel. The authors examined the trust-related perspectives of 16 mothers of children with various disabilities at all levels of the P—12 educational system. Analysis of the mothers' responses to face-to-face interview questions yielded three primary categories that seem to influence trust: family characteristics, teacher characteristics, and school characteristics. Discussion focuses on the mothers' difficulty in defining their levels of trust and on the roles of authentic caring, child-focused orientation, communication, knowledge about child characteristics, and school climate and teaming factors that appear to facilitate or inhibit trust. Discussion also addresses implications of these findings for school leadership and the establishment of healthy family—professional relationships, especially as they affect the lives of students and families in need of special education support.
Oxidative Degradation of MTBE by Pyrite-Activated Persulfate: Proposed Reaction Pathways (2010)

This bench-scale study investigated the feasibility of activated persulfate (S2O82−) oxidation of methyl tert-butyl ether (MTBE), using pyrite (FeS2) as the source of ferrous ion activators. Under the FeS2-activated S2O82− condition, the sulfate free radical (SO4−•) is the predominant reactive species generated. The oxidation reactions were able to completely degrade MTBE when given sufficient doses of FeS2 and S2O82− and sufficient reaction time (e.g., 3 g FeS2/L and 5 g Na2S2O8/L within 4 h) and exhibited generation and subsequent degradation of the primary MTBE degradation intermediate products including tert-butyl formate, tert-butyl alcohol, methyl acetate, and acetone. The detailed reaction mechanism proposed for a SO4−•-driven oxidation process in this paper indicates that the destruction of MTBE most likely happens through α-hydrogen abstraction via attack of the SO4−• at the intermediate methoxy group.
A novel algorithm to form stable clusters in vehicular ad hoc networks on highways (2012)

Clustering in vehicular ad hoc networks (VANET) is one of the control schemes used to make VANET global topology less dynamic. Many of the VANET clustering algorithms are derived from mobile ad hoc networks (MANET). However, VANET nodes are characterized by their high mobility, and the existence of VANET nodes in the same geographic proximity does not mean that they exhibit the same mobility patterns. Therefore, VANET clustering schemes should take into consideration the degree of the speed difference among neighboring nodes to produce relatively stable clustering structure. In this paper, we introduce a new clustering technique suitable for the VANET environment on highways with the aim of enhancing the stability of the network topology. This technique takes the speed difference as a parameter to create relatively stable cluster structure. We also developed a new multi-metric algorithm for cluster-head elections. A simulation was conducted to evaluate our method and compare it with the most commonly used clustering methods. The simulation results show that our technique provides more stable cluster structure on the locale scale which results in a more stable network structure on the global scale. The proposed technique reduces the average number of clusters changed per vehicle by 34-46%, and increases the average cluster lifetime by 20-48% compared to the existing techniques.
CD43 in the nucleus and cytoplasm of lung cancer is a potential therapeutic target (2012)

CD43 is a transmembrane sialoglycoprotein. Normally the molecule is only produced by white blood cells where it regulates functions such as intercellular adhesion, intracellular signaling, apoptosis, migration and proliferation. Two CD43 antibodies were used to interrogate 66 cases of non-small cell lung cancer (NSCLC) and 24 cases of small cell lung cancer (SCLC). In addition, we engineered the CD43-positive lung cancer cell line A549 to stably express either non-targeted or CD43-targeted small-interfering RNA (siRNA). These lines were then subjected to in vitro assays of apoptosis, natural killer (NK) cell cytotoxicity, intercellular adhesion and transendothelial migration. A xenograft mouse model evaluated the ability of the lines to grow primary tumors in vivo. CD43 was found to be expressed in the majority of both SCLC and NSCLC. Inclusive of CD43-negative tumors, differential patterns of nuclear and cytoplasmic expression of CD43 define four molecular subcategories of lung cancer. Targeting CD43 in A549 lung cancer cells, increased homotypic adhesion, decreased heterotypic adhesion and transendothelial migration, increased susceptibility to apoptosis and increased vulnerability to lysis by NK cells. Furthermore, targeting inhibited the growth of primary tumors in nude mice.
Single step electrochemical synthesis of hydrophilic/hydrophobic Ag5 and Ag6 blue luminescent clusters (2012)

Well-defined Ag(5) and Ag(6) dodecanethiol/tetrabutyl ammonium-protected clusters were prepared by a one-pot electrochemical method. Ag clusters show bright and photostable emissions. The presence of a dual capping renders the silver clusters soluble in both organic and aqueous solvents.
Lacrimal Duct Occlusion for the Treatment of Dry Eye (2005)

The most widespread treatment for dry eyes in clinical practice is an instillation containing artificial tear fluid. When an instillation does not ameliorate dry eye, we use punctal plugs. The insertion of punctal plugs is an eminent curative that positively improves the corneal and conjunctival epithelial disorders and the amount of lacrimal fluid accumulated in the conjunctival sac. We shall introduce the lacrimal duct occlusion utilizing atelocollagen solutions, which solves many of the issues induced by conventional methods.
Chromosomal DNA fingerprinting analysis using the insertion sequence IS6110 and the repetitive element DR as strain-specific markers for epidemiological study of tuberculosis in French Polynesia (1995)

The polymorphism of Mycobacterium tuberculosis strains was evaluated in French Polynesia, an area with a low incidence of tuberculosis and a population which has been geographically stable during recent decades. Nonrepetitive strains isolated from 64 patients during 1991 and 1992 were subjected to DNA restriction fragment length polymorphism (RFLP) analysis, using the insertion sequence IS6110 and the repetitive element DR as probes. Thirty-eight different IS6110 RFLP types were identified. They could be clustered in 11 groups. All the members of each group are identical or differ by one to three bands. All the other strains are gathered in the miscellaneous group. In some cases, transmission of strains with identical RFLP types between patients of the same family or between patients living in the same area was identified. Strains exhibiting similar IS6110 RFLP types also exhibited identical DR RFLP patterns, confirming that strains with similar types were genetically linked. Strains belonging to two different IS6110 clusters exhibited the same DR RFLP type. These data may also indicate a common origin for these strains and evolution to new IS6110 types. The results obtained in this study suggest that not only reactivation of latent tuberculous infections but also active transmissions are still occurring in French Polynesia.

A novel CAD framework for substrate modeling (2014)

This paper presents a novel Computer-Aided-Design (CAD) framework for 3D extraction of the substrate electrical network. The proposed CAD tool (framework) models efficiently the minority carrier propagation inside substrate network especially for smart power ICs. Today, the minority carrier propagation into the substrate is ignored in existing SPICE simulators. It can be simulated using finite element methods in TCAD. Generally, TCAD simulations are accurates but take long time. Thus, they become of limited help for large scale ICs involving hundreds of transistors. In the context of the FP7 AUTOMICS project, the extraction tool will take into consideration the minority carriers effects. It will allow the designer to predict the minority carrier propagation through the substrate. This can be useful in evaluation the efficiency of ESD protection and latchup faults due to this leackage current in the substrate specially in HV/HT applications. With the proposed substrate network, the three-dimensional layout parasitics are constructed and substrate noise is simulated before first silicon fabrication. A simple diode example is illustrated to demonstrate the principal idea of the extraction tool.

Substitution of amino acids Asp-85, Asp-212, and Arg-82 in bacteriorhodopsin affects the proton release phase of the pump and the pK of the Schiff base. (1990)

Photocycle and flash-induced proton release and uptake were investigated for bacteriorhodopsin mutants in which Asp-85 was replaced by Ala, Asn, or Glu; Asp-212 was replaced by Asn or Glu; Asp-115 was replaced by Ala, Asn, or Glu; Asp-96 was replaced by Ala, Asn, or Glu; and Arg-82 was replaced by Ala or Gln in dimyristoylphosphatidylcholine/3-[(3-cholamidopropyl)dimethylammonio]-1- propanesulfonate micelles at pH 7.3. In the Asp-85----Ala and Asp-85----Asn mutants, the absence of the charged carboxyl group leads to a blue chromophore at 600 and 595 nm, respectively, and lowers the pK of the Schiff base deprotonation to 8.2 and 7, respectively, suggesting a role for Asp-85 as counterion to the Schiff base. The early part of the photocycles of the Asp-85----Ala and Asp-85----Asn mutants is strongly perturbed; the formation of a weak M-like intermediate is slowed down about 100-fold over wild type. In both mutants, proton release is also slower but clearly precedes the rise of M. The amplitude of the early (less than 0.2 microseconds) reversed photovoltage component in the Asp-85----Asn mutant is very large, and the net charge displacement is close to zero, indicating proton release and uptake on the cytoplasmic side of the membrane. The data suggest an obligatory role for Asp-85 in the efficient deprotonation of the Schiff base and in the proton release phase, probably as proton acceptor. In the Asp-212----Asn mutant, the rise of the absorbance change at 410 nm is slowed down to 220 microsecond, its amplitude is small, and the release of protons is delayed to 1.9 ms. The absorbance changes at 650 nm indicate perturbations in the early time range with a slow K intermediate. Thus Asp-212 also participates in the early events of charge translocation and deprotonation of the Schiff base. In the Arg-82----Gln mutant, no net transient proton release was observed, whereas, in the Arg-82----Ala mutant, uptake and release were reversed. The pK shift of the purple-to-blue transition in the Asp-85----Glu, Arg-82----Ala, and Arg-82----Gln mutants and the similarity in the photocycle and photoelectrical signals of the Asp-85----Ala, Asp-85----Asn, and Asp-212----Asn mutants suggest the interaction between Asp-85, Arg-82, Asp-212, and the Schiff base as essential for proton release.
The Angiogenic Effect of Tissue Factor on Tumors and Wounds (1998)

We report a novel function of tissue factor (TF) as an angiogenic factor in malignant and non-malignant cells and tissue. When methylcholanthrene A-induced murine fibrosarcoma (Meth-A sarcoma) was stably transfected with mouse TF (mTF) cDNA (pXT1 expression vector), its vascularization in vivo was significantly enhanced, whereas TF-antisense suppressed the vascularization and tumor growth. In vitro expression of vascular endothelial growth factor (VEGF) was enhanced with stable transfection of mTF (pcDNA3 expression vector) into a mouse fibroblast cell line (NIH3T3). Moreover, in vivo topical transfection of mTF (pcDNA3) showed an enhanced vascularization and healing in a diabetic mouse wound-healing model. This effect of TF as an angiogenic factor might be useful as an antitumor therapy against hypervascular tumors or as a novel agent against delayed wound healing.
Analysis of interleaved arrays of waveguide elements (1971)

An analysis is presented of multiple interleaved arrays of waveguide radiators operating at different frequencies. The approach is a generalization of the analysis of an infinite array at a single frequency. The presence of the low-frequency elements affects the radiation characteristics of the high-frequency elements and generates grating lobes which do not appear in a single-frequency array. Furthermore, power is coupled 'into the low-frequency waveguides when the high-frequency elements are excited. Numerical examples are presented which show that these effects are not severe.
Expression in <i>E. coli</i> and purification of a chimeric p22‐NS3 recombinant antigen of Hepatitis C Virus (HCV) (1993)

A recombinant antigen (p22-NS3), possessing putative HCV nucleocapsid protein (p22) and non-structural protein 3 (NS3) epitopes, was heavily expressed in E. coli and purified. The p22-NS3 purified recombinant antigen strongly reacts with sera containing human antibodies directed against p22 and NS3 providing a starting point for the design of an HCV single all-encompassing antigen for a blood screening assay.
Air gap technology by selective ozone/TEOS deposition (2004)

A technology for fabrication of air gaps is presented which is based upon selective ozone/TEOS deposition of oxide. Due to the isotropic growth direction of this process, some disadvantages of the more common approaches by nonconformal CVD processes can be avoided. It is demonstrated that air gap technology has the potential to reduce the capacitance between adjacent metal lines roughly by a factor of 2 compared to full structures without air gaps.

The Spirituality of Louise de Marillac: Formed by the Spirit for Charity (1991)

This article presents “a spiritual portrait” of Louise de Marillac as reconstructed from Vincent’s letters to her and explores her prayer life using her writings. After 1623, Louise went on a complex and difficult journey of faith that was shaped by her temperament, her experience, and her time. She was extremely intelligent and capable, but also needed frequent spiritual reassurance, which Vincent de Paul provided throughout their relationship. However, she was well educated in the Bible and in spiritual practices before she met him. Her beginning was ascetic, with a demanding prayer schedule. Such discipline was related to her self-doubt. She was freed from this by service to Christ as she saw him in the poor and a corresponding deeper discovery of God’s love. Her interior life was still essential, but it was more spontaneous. Vincent helped her reach this end by teaching her to trust in providence. Louise was then able to accomplish her work with the Confraternities of Charity.
Estimation of Hox gene cluster number in lampreys (1998)

Hox gene clusters are linked arrays of related homeobox genes with important roles in patterning the main body axis of animal embryos. Almost all invertebrates analyzed in detail, including a cephalochordate, have a single Hox gene cluster. In contrast, mammals have four such clusters inferred to have arisen by duplication. Data from other jawed vertebrates, including teleost fish, suggest they have at least four Hox gene clusters, implying that cluster duplication dates to very early in vertebrate evolution. Lampreys descended from one of the earliest vertebrate lineages and are thus critical in dating the duplication events. Here we analyze the Hox gene complement of a freshwater lamprey, Lampetra, using degenerate PCR. By analysis of the DNA sequences, deduced protein sequences, and by comparison to previous data from the distantly related sea lamprey, we conclude that lampreys have approximately 21 Hox genes from paralogous groups 1-10, plus a group 13 Hox gene. The data support the presence of three Hox gene clusters in lampreys more strongly than they support the presence of one, two or four gene clusters. We discuss how this situation may have arisen in evolution.
Ravel-XL: a hardware accelerator for assigned-delay compiled-code logic gate simulation (2002)

We describe the design of Ravel-XL, a hardware accelerator for assigned-delay compiled-code logic gate simulation. After a brief review of the underlying Ravel simulation algorithm, we describe the major factors that influenced the hardware design, particularly the interaction between the instruction execution and operand bandwidth requirements. The initial CMOS VLSI implementation of the accelerator contains a 2K word data cache, occupies approximately 1.9 cm/sup 2/ of die area with 256 pins and approximately 900,000 transistors. Simulation results predicts operation at a clock rate of 33 MHz. This provides a speedup of about 50 over the software implementation of Ravel, about 50 over a compiled event-driven simulator, and about 500 over an interpreted event-driven simulator. We conclude with some planned design improvements that will allow an approximate doubling of the clock rate.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Both the enantiomers ( - 96% e.e.) of (2Z, 6Z)-2, 6-nonadien-4-olide, a possible pheromone of Aphomia gularis, were synthesized by resolving an acetylenic intermediate.
The <i>Salmonella enterica</i> Serotype Typhimurium <i>lpf</i> , <i>bcf</i> , <i>stb</i> , <i>stc</i> , <i>std</i> , and <i>sth</i> Fimbrial Operons Are Required for Intestinal Persistence in Mice (2005)

Salmonella enterica serotype Typhimurium causes human infections that can frequently be traced back through the food chain to healthy livestock whose intestine is colonized by the pathogen. Little is known about the genes important for intestinal carriage of S. enterica serotype Typhimurium in vertebrate animals. Here we characterized the role of 10 fimbrial operons, agf, fim, lpf, pef, bcf, stb, stc, std, stf, and sth, using competitive infection experiments performed in genetically susceptible (BALB/c) and resistant (CBA) mice. Deletion of agfAB, fimAICDHF, lpfABCDE, pefABCDI, bcfABCDEFG, stbABCD, stcABCD, stdAB, stfACDEFG, or sthABCDE did not reduce the ability of S. enterica serotype Typhimurium to colonize the spleen and cecum of BALB/c mice 5 days after infection. Similarly, deletion of agfAB, fimAICDHF, pefABCDI, and stfACDEFG did not result in reduced recovery of S. enterica serotype Typhimurium from fecal samples collected from infected CBA mice over a 30-day time period. However, S. enterica serotype Typhimurium strains carrying deletions in lpfABCDE, bcfABCDEFG, stbABCD, stcABCD, stdAB, or sthABCDE were recovered at significantly reduced numbers from the feces of CBA mice. There was a good correlation (R(2) = 0.9626) between competitive indices in the cecum and fecal samples of CBA mice at 30 days after infection, suggesting that the recovery of S. enterica serotype Typhimurium from fecal samples closely reflected its ability to colonize the cecum. Collectively, these data show that six fimbrial operons (lpf, bcf, stb, stc, std, and sth) contribute to long-term intestinal carriage of S. enterica serotype Typhimurium in genetically resistant mice.
