Coated conductors on tubular metallic wires by combined chemical approaches (2009)

Fabrication of YBCO wires has been explored by using tubes formed from textured tapes. The texture of tubes made from Ni-5 at % W is characterized as a bi-axial texture developing along both the axis and the circumference of the cylinder. The deposition of a buffer layer by metal-organic deposition on such a tube is described with the practical example of La2Zr2O7. A superconducting YBCO layer is deposited on top; its texture and the electrical performance are evaluated. In the present state of the art, the YBCO is superconducting at 88 K; it is textured, but can carry only week supercurrents due to insufficient percolation paths. Improvements of the process are underway to enhance the transport current properties
Modular DIPS, 2.5-kWe modules for lunar/Mars surface applications, design point selection summary (1993)

The Dynamic Isotope Power System (DIPS) Demonstration Program is currently focused on the development of a standardized 2.5‐kWe portable generator for multiple applications on the lunar or Martian surface. An optimum system configuration has been developed fot the 2.5‐kWe DIPS module that provides a system with a radiator area, which is small and manageable without significantly impacting the system mass, efficiency, and technological risk. The 2.5‐kWe DIPS module configuration was developed based on a systematic series of studies. Initially, technology breakpoints in the DIPS component and subsystem designs were identified. Based on the technology assessments, the maximum design temperature for the system was selected and various system and subsystem configurations were evaluated. Finally, the subsystem and system designs for the selected configuration were optimized using a detailed system design optimization computer code.
Relationship between Structural and Stress Relaxation in a Block-Copolymer Melt (2006)

The relationship between structural relaxation on molecular length scales and macroscopic stress relaxation was explored in a disordered block-copolymer melt. Experiments show that the structural relaxation time, measured by x-ray photon correlation spectroscopy is larger than the terminal stress relaxation time, measured by rheology, by factors as large as 100. We demonstrate that the structural relaxation data are dominated by the diffusion of intact micelles while the stress relaxation data are dominated by contributions due to disordered concentration fluctuations.
An ontology based context aware modelling and reasoning to enhance human environment interaction (2007)

La convergence récente de l'informatique ambiante et des systèmes sensibles au contexte a généré un intérêt important pour les applications qui exploitent des aspects de l'environnement contextuel pour améliorer l'interaction implicite de l'utilisateur, fournir des services adaptables, présenter de l'information pertinente, et gérer des mécanismes d'adaptation. Cependant, en raison du manque et d'absence des solutions techniques génériques capables de couvrir la continuité de l'interaction entre plusieurs espaces d'interaction, la compléxité des besoins, et l'hétérogéneité des dispositifs d'interaction, il demeure très difficile le développement des applications sensibles au contexte et les développeurs doivent traiter éventuellement beaucoup de verrous liées à la représentation, à la détection, à l'interprétation, au stockage, au raisonnement et l'adaptation du contexte. Afin de remédier à cette situation, il y a un besoin de mieux comprendre le processus de conception lié aux applications sensibles au contexte, l'architecture supportant les différentes phases de traitement de contexte, et améliorer l'abstraction de la programmation afin de soulager le prototypage des applications. Cette recherche s'est concentrée sur l'infrastructure logicielle (Framework) permettant les développements d'applications sensibles au contexte. Cette dissertation présente une analyse de l'ensemble des conditions pour le développement des applications contextuelles. Cette analyse nous a permis de proposer un modèle conceptuel basé sur les ontologies sémantiques, une infrastructure logicielle pour le traitement du contexte et un ensemble de bibliothèques. La recherche rapportée ici étudie : comment le contexte peut être acquis, distribué, et utilisé et comment ca permet d'affecter l'interaction homme environnement.
Pediatric Urology (2007)

Context: The evidence regarding risk factors for recurrent urinary tract infection (UTI) and the risks and benefits of antimicrobial prophylaxis in children is scant. Objectives: To identify risk factors for recurrent UTI in a pediatric primary care cohort, to determine the association between antimicrobial prophylaxis and recurrent UTI, and to identify the risk factors for resistance among recurrent UTIs. Design, Patients and Setting: From a network of 27 primary care pediatric practices in urban, suburban, and semirural areas spanning 3 states, a cohort of children aged 6 years or younger who were diagnosed with first UTI between July 1, 2001, and May 31, 2006, was assembled. Time-to-event analysis was used to determine risk factors for recurrent UTI and the association between antimicrobial prophylaxis and recurrent UTI, and a nested case-control study was performed among children with recurrent UTI to identify risk factors for resistant infections. Main Outcome Measures: Time to recurrent UTI and antimicrobial resistance of recurrent UTI pathogens. RESULTS: Among 74 974 children in the network, 611 (0.007 per person-year) had a first UTI and 83 (0.12 per person-year after first UTI) had a recurrent UTI. In multivariable Cox time-to-event models, factors associated with increased risk of recurrent UTI included white race (0.17 per person-year; hazard ratio [HR], 1.97; 95% confidence interval [CI], 1.22-3.16), age 3 to 4 years (0.22 per person-year; HR, 2.75; 95% CI, 1.37-5.51), age 4 to 5 years (0.19 per person-year; HR, 2.47; 95% CI, 1.19-5.12), and grade 4 to 5 vesicoureteral reflux (0.60 per person-year; HR, 4.38; 95% CI,. Sex and grade 1 to 3 vesicoureteral reflux were not associated with risk of recurrence. Antimicrobial prophylaxis was not associated with decreased risk of recurrent UTI (HR, 1.01; 95% CI, 0.50-2.02), even after adjusting for propensity to receive prophylaxis, but was a risk factor for antibimicrobial resistance among children with recurrent UTI (HR, 7.50; 95% CI,. Conclusion: Among the children in this study, antimicrobial prophylaxis was not associated with decreased risk of recurrent UTI, but was associated with increased risk of resistant infections.
Micromagnetic analysis of injection locking in spin-transfer nano-oscillators (2010)

The injection-locking mechanism of a spin-transfer nano-oscillator is studied for a system which is traversed by a spin-polarized electric current with both dc and ac components. The uniform mode theory is used to predict the control parameters for the synchronization between the magnetization self-oscillation and the external microwave current. It is found that micromagnetic simulations at zero temperature are in very good agreement with the theory, showing that magnetization dynamics is practically uniform in space. Then, the effect of temperature on synchronized regimes is analyzed. The locking band as well as the hysteretic character of the oscillation response are determined as function of the control parameters. Computations of the power spectral densities (PSD) of injection-locked and unlocked oscillations reveal that synchronized oscillations are quite stable with respect to thermal fluctuations. Secondary peaks in the PSD of injection-locked oscillations are reported and theoretically explained.

New Biocompatible Polyesters Derived from α-Amino Acids: Hydrolytic Degradation Behavior (2010)

New polymers were synthesized from α-hydroxy acids derived from the natural amino acids Ile, Leu, Phe, and Val, combined with lactic acid, glycolic acid and 6-hydroxyhexanoic acid by direct condensation. The toxicity was determined and the degradation process of these polyesters was investigated under physiological conditions by analyzing the composition of the degraded polymers and the oligomers cleaved in the buffer medium. The polymers were found to be non toxic to two cell lines. Polymers displayed a biphasic degradation behavior. In most cases, a linear relationship was found between the weight loss constant and the hydrophobicity of the polymers, Log P. Regarding the second stage of weight loss, it is apparent that polymers derived from α-hydroxy(L)isoleucine ((L)HOIle) and α-hydroxy(L)Valine ((L)HOVal) degraded much faster than those derived from α-hydroxy(L)leucine ((L)HOLeu) and α-hydroxy(L)phenylalanine ((L)HOPhe), probably due to different spatial orientation of the side chains. Copolymers of 6-hydroxyhexanoic acid displayed slow degradation rates as expected, whereas the degradation profile of copolymers of lactic acid was similar to the other homopolymers. These new polyesters may serve as potential biocompatible materials for medical applications.

Clinical trials decision-making in African American patients with cancer: The role of cancer-coping religious beliefs. (2012)

e16543 Background: Religious beliefs have been shown to play a significant role for African American patients coping with a cancer diagnosis. Less established is how these beliefs may relate to specific treatment decisions. The purpose of this study was to explore how patients used religious beliefs for coping and examine the relationship with specific attitudes towards and intention to enroll in a clinical trial (CT). Methods: Participants were 108 active treatment patients at a large urban cancer institute. The primary study outcome was self-reported likelihood to participate in a cancer therapeutic trial. Participant attitudes towards CTs were assessed using the Attitudes and Intention to Enroll in Therapeutic Clinical Trials instrument. The God as Healer construct was used to assess the perception of God as a healer, either directly or through the intervention of physicians and medicine. Kruskal-Wallis and Wilcoxon Mann-Whitney tests were used to examine the relationship between the sum scores of religious beliefs, attitude items and likelihood of patients to participate in CT. Results: The results of these analyses provided limited support for a direct relationship of belief in God as a healer and intention to enroll in a CT. Spearman’s correlation analysis revealed a statistically significant relationship between a belief in God as direct healer with ‘Distrust of doctors’ (r s = 0.26, p < .01 ); and God as direct healer with ‘Fear of losing one’s rights after signing a CT consent form’ (r s = 0.24, p < .05). While not statistically significant in this sample, those with a higher belief in ‘God as a healer through medicine and doctors’ had more negative attitudes of ‘fear of being treated unfairly on a CT due to being poor or a minority’, and of ‘losing their rights after signing a CT consent form’. Conclusions: These findings suggest providers should be aware of the culturally specific roles that religious/spiritual beliefs play in African American patients’ attitudes towards CTs and how they may align with CT decision-making.

A global view of protein expression in human cells, tissues, and organs (2009)

Defining the protein profiles of tissues and organs is critical to understanding the unique characteristics of the various cell types in the human body. In this study, we report on an anatomically comprehensive analysis of 4842 protein profiles in 48 human tissues and 45 human cell lines. A detailed analysis of over 2 million manually annotated, high-resolution, immunohistochemistry-based images showed a high fraction (>65%) of expressed proteins in most cells and tissues, with very few proteins (<2%) detected in any single cell type. Similarly, confocal microscopy in three human cell lines detected expression of more than 70% of the analyzed proteins. Despite this ubiquitous expression, hierarchical clustering analysis, based on global protein expression patterns, shows that the analyzed cells can be still subdivided into groups according to the current concepts of histology and cellular differentiation. This study suggests that tissue specificity is achieved by precise regulation of protein levels in space and time, and that different tissues in the body acquire their unique characteristics by controlling not which proteins are expressed but how much of each is produced.
Scaling properties of a percolation model with long-range correlations (1996)

We present the results of Monte Carlo simulations of a percolation model with long-range correlations in two and three dimensions. The correlations are generated by a fractional Brownian motion. The nature of the percolation transition in this model is discussed. The percolation thresholds and the critical exponents of the model are calculated. The exponents are found to be mostly nonuniversal and dependent on a parameter that characterizes the nature of the correlations. Some possible applications of the model are discussed in detail, including flow in field-scale porous media (withmegascopic disorder) with a given permeability distribution, and estimating their effective permeability, and transport and dispersion in geological formations and explaining the anomalous and nonuniversal behavior of the dispersivity that has been observed in many field-scale experiments, in terms of the nonuniversal properties of our model. \textcopyright{} 1996 The American Physical Society.

Transformation of Stereoscopic Images for 3D Perception Improvement (2012)

최근 3DTV 및 3D 디스플레이가 공급되면서 입체영상 제작도 활발히 진행되고 있다. 입체영상은 좌영상과 우영상으로 만들어지는데, 제작된 입체영상은 수정 없이 그대로 시청자에게 공급되고 있다. 2D 영상도 고주파 성분을 이용하여 깊이감을 높이고, 색보정을 거처 자연색과 유사한 색을 재현하는 등의 연구는 오랫동안 진행되어 왔다. 이 기술을 입체영상에 적용하고자 하는 것이 본 논문의 목적이다. 기 제작된 입체영상의 컬러를 변환함으로써 3D 입체감을 개선하는 방법을 제안한다. 이를 위해서 본 논문에서는 스테레오 영상으로부터 깊이맵을 획득하고, 기존 컬러 변환을 통한 2D 영상의 지각 깊이감 개선을 입체영상에 적용하여, 3D 입체감을 향상시키는 방법을 제안한다. 이를 위해 스테레오 정합 방법과 컬러 변환 방법으로 대조 변환 및 배경 다크닝 방법을 제안하고, 실험을 통해 제안 방법이 상기 목적을 얻을 수 있는 것을 검증하였다. Recently, 3DTV and 3D displays have been released in the market. Accordingly, the production of stereoscopic images has gained much interest. Stereoscopic image being composed of left and right images are currently delivered to viewers without any modifications. The researches on the enhancement of depth perception using high-frequency components and the re-production of natural color by color compensation have been carried out for 2D images. The application of such 2D technologies to 3D stereoscopic images is an aim of this paper. This paper proposes the enhancement of 3D perception by color transformation. For this, we propose a stereo matching method for obtaining a depth map and two color transformation methods such as contrast transformation and background darkening. The effectiveness of the proposed method was verified through experiments.
Fine structure of 5,10,15,20-tetrakis(m-hydroxyphenyl)chlorin (m-THPC): a 1H, 13C and 15N NMR study (1994)

The 1H, 13C and natural abundance 15N NMR spectra of tetrakis(m-hydroxyphenyl)chlorin (m-THPC) are assigned through the complementary analysis of the data from one-dimensional, and both homo- and hetero-nuclear two-dimensional NMR experiments. The analysis of the 1H and 13C spectra showed that the symmetry of the structure includes an effective mirror plane, σv, and the 1H–15N coupling constant of 99 Hz (measured from the ‘inverse-mode’1H–15N 2D experiment) showed that the central imino protons undergo slow intramolecular tautomeric exchange. The single 15N chemical shift (δ 111.8 relative to 15NH4+) of the proton-bearing nitrogens is characteristic of a ‘pyrrole’ type, and the long range coupling 1H chemical shift correlation (2D) spectrum showed that, on the NMR time scale, the imino hydrogens are localised on five-membered rings that are not in the σv plane. Taken together these data prove that the fine structure of m-THPC is correctly represented with the imino hydrogens placed on opposite rings which are not reduced, as shown in structure 4.
H7N6 Low Pathogenic Avian Influenza outbreak in commercial turkey farms in Chile caused by a native South American Lineage (2019)

SUMMARY In December of 2016, low pathogenic avian influenza (LPAI) caused by an H7N6 subtype was confirmed in a grow-out turkey farm located in Valparaiso Region, Chile. Depopulation of exposed animals, zoning, animal movement control and active surveillance were implemented to contain the outbreak. Two weeks later, a second turkey grow-out farm located 70 km north of the first site was also infected by H7N6 LPAI, which subsequently spilled over to one backyard poultry flock. The virus involved in the outbreak shared a close genetic relationship with viruses collected from Chilean aquatic birds’ viruses. The A/turkey/Chile/2017(H7N6) LPAI virus belonged to a native South American lineage. Based on the H7 and most of the internal genes phylogenies, these viruses were also closely related to the viruses that caused a highly pathogenic avian influenza outbreak in Chile in 2002. Results from this study help understand the regional dynamics of influenza outbreaks, highlighting the importance of local native viruses circulating in the natural reservoir hosts.

Carrier profiling of GaAs/GaAlAs multilayer structures (heterojunction bipolar transistor and heterojunction p–i–n photodiode) by electrochemical capacitance–voltage technique is described. Optimum measurement parameters (electrolyte type, etching and measurement voltages, etc.) are established. The results are compared with those of spreading resistance profiling and transmission electron microscopy. Some specific problems are discussed.
Mycotic omasitis and rumenitis as sequelae to sepsis in dairy cattle: Six cases (1979–1986) (1989)

Medical records of 6 cows with mycotic rumenitis or omasitis, but no history of grain engorgement, were reviewed. A diagnosis was made at necropsy in all cows, although the condition was suspected before euthanasia in 3 cows. Common clinical findings included inappetence, rumen stasis, fluid rumen contents, and scant, pasty, or loose feces. Postmortem findings included severe ulcerative rumenitis or omasitis, with thrombosis of blood vessels in the submucosa, and branching, septate fungal hyphae abundant in inflamed tissues. In these cows, mycotic omasitis and rumenitis were thought to be sequelae of sepsis, with reflux of abomasal fluid into the forestomach and broad spectrum antimicrobial therapy as possible predisposing factors for mycotic infections.
Predicting endocrine therapy responsiveness in breast cancer. (2009)

Endocrine therapy is one of the most effective treatment strategies for breast cancer. However, in the adjuvant setting, up to 40% to 50% of patients with estrogen receptor (ER)-positive breast cancers relapse despite these interventions. Although ER and HER2 analysis has increased our ability to predict which patients will benefit from endocrine therapy, further improvement is needed, most specifically for patients with ER-positive, HER2-negative disease. Recent advances in genomic technology have made it possible to classify breast cancers into risk categories with significant prognostic implications. However, the predictive value of these tests remains the subject of investigation. Long-term follow-up of neoadjuvant endocrine therapy studies suggests that the in vivo assessment of therapeutic efficacy provided by this treatment approach is also valuable in predicting outcome. Indeed, the Preoperative Endocrine Prognostic Index (PEPI), based on tumor pathologic staging and expression levels of ER and Ki67 following 3 to 4 months of neoadjuvant endocrine therapy, reproducibly predicts long-term outcomes of hormone receptor-positive breast cancer. This article reviews ongoing progress in the effort to identify predictors of endocrine therapy responsiveness for breast cancer and discusses the value of "pre-treatment" vs "on-treatment" tumor profiling for predicting outcomes.
