Pseudomorphic Growth of a Single Element Quasiperiodic Ultrathin Film on a Quasicrystal Substrate

An ultrathin film with a periodic interlayer spacing was grown by the deposition of Cu atoms on thefivefold surface of the icosahedral Al70 Pd21 Mn9 quasicrystal. For coverages from 5 to 25 monolayers, a distinctive quasiperiodic low-energy electron diffraction pattern is observed. Scanning tunneling microscopy images show that the in-plane structure comprises rows having separations of S = 4.5 �0.2 �A and L = 7.3 0.3 A, whose ratio equals � =1.618... within experimental error. The sequences of such row separations form segments of terms of the Fibonacci sequence, indicative of the formation of a pseudomorphic Cu film

Radiative Muon Capture on Hydrogen and the Induced Pseudoscalar Coupling

The first measurement of the elementary process $\mu^- p \rightarrow \nu_{\mu} n \gamma$ is reported. A photon pair spectrometer was used to measure the partial branching ratio ($2.10 \pm 0.22) \times 10^{-8}$ for photons of k > 60 MeV. The value of the weak pseudoscalar coupling constant determined from the partial branching ratio is $g_p(q^{2}=-0.88m_{\mu}^2) = (9.8 \pm 0.7 \pm 0.3) \cdot g_a(0)$, where the first error is the quadrature sum of statistical and systematic uncertainties and the second error is due to the uncertainty in $\lambda_{op}$, the decay rate of the ortho to para $p \mu p$ molecule. This value of g_p is $\sim$1.5 times the prediction of PCAC and pion-pole dominance.Comment: 13 pages, RevTeX type, 3 figures (encapsulated postscript), submitted to Phys. Rev. Let

Rider energy expenditure during high intensity horse activity and the potential for health benefits

Obesity and disease associated with sedentary lifestyles have become major concerns in the United States. Exercise has been described as a crucial part of disease prevention and overall health, with activities such as biking or running cited as examples. Horseback riding is a popular activity; however, little information on the exercise value of horseback riding exists. The objective of this experiment was to define the energy expenditure of participants in several common riding events. All procedures were approved by the Texas A&M Institutional Review Board and Institutional Animal Care and Use Committee; subjects gave written consent prior to participation. Twenty subjects completed each of three riding tests: a 45min walk-trot-canter ride (WTC), a reining pattern, and a cutting pattern while wearing a telemetric gas analyzer. Anthropometric data were obtained for each subject through DEXA scans. Total energy expenditure (tEE), as well as mean and peak energy expenditure per minute (EE/min), metabolic equivalents of task (MET), heart rate (HR), respiratory frequency (RF), pulmonary ventilation (VE), oxygen consumption (VO2), relative oxygen consumption (relVO2) and carbon dioxide production (­VCO2)were measured. Mean energy expenditure per minute, and HR responses were greater (P \u3c 0.05) for reining (6.96±0.23Kcal/min, 163.28±4.2bpm) and cutting (4.98±0.23Kcal/min, 146.9±4.2bpm) than for WTC (4.27±0.23Kcal/min, 131.5±4.2bpm). When WTC test was evaluated by gait component, mean EE/min and MET increased as gait speed increased. Mean EE/min and MET were higher (P \u3c 0.05) for riders at long trot (6.9±0.21Kcal/min, 6.19±0.21MET) and canter (6.93±0.21Kcal/min, 5.95±0.21MET) gaits than during the walk (2.34±0.21Kcal.min, 2.01±0.21MET) or trot (3.5±0.21Kcal/min, 3.2±0.21MET) gaits. Similar patterns were observed for RF, VE, VO2, VCO2 and RelVO2 across disciplines and by gait component. The tEE (194.7±3.84kcal/min) and mean MET (4.27±0.23MET) observed during the 45-min WTC ride were within current national recommendations of intensity (3-6MET), time (\u3e30min) and calories burned (~1000Kcal/wk). The results of this study provide novel information about exercise intensity values for horseback activities and differences among riding disciplines measured in real time using a portable system. Riders engaged in cutting and reining experienced more intense exercise in short durations, while WTC provided a greater total energy expenditure. These data suggest that it is possible, if riding at the more intense gaits such as long trot and canter, for health benefits to be achieved through accumulated weekly horseback riding exercise

On The Necessary Connection Between Law and Ethics: The Ethical Content of Law

I defend the claim that there is a necessary connection between law and ethics. I do so by analogy with other social rule-based systems, such as capitalism. Most social rule-based systems are (in part) conceptually understood by the collective overall content of their rules. If legal systems, which are also social rule-based systems, are best understood in the same way, then the collective overall content of legal systems’ rules tells us how to understand the concept of law. One possibility for the collective overall content of legal systems’ rules is ethical content. If so, then there is a necessary connection between law and ethics

Hebrew and Geologic Analysis of the Chronology and Parallelism of the Flood: Implications for Interpretation of the Geologic Record

In the Hebrew Flood narrative the syntax is conducive to the identification of the chronological sequence of events. Syntactical sequences confirm that the total time aboard the ark was 371 days. Noah’s family and the animals entered the ark the same day the Flood began — the day noted in 7:11 by year, month, and day. The 7 days of 7:10 are a fulfillment of the declaration given in 7:4 and are not part of the overall chronology of the Flood itself. There are two 40-day periods. The first 40 days began on the date given in 7:11 and are part of the first 150 days of the Flood. The second 40-day period began on the day after the mountaintops were seen, day 226. After this second 40-day period, three periods of 1 week are related to the releases of the raven and the dove. On day 315 the surface of the ground was described as drying (8:13) and the earth was dry on day 371, the day the ark’s occupants disembarked. An analysis of the narrative as a unit supports a global cataclysmic Flood. A natural division of the Flood occurs in two main parts: 150 days of prevailing waters and 221 days of subsidence. The purpose of the first 150 days was to obliterate all terrestrial life including the original continent(s). Heavy rains were restrained after those 150 days (not after 40 days) when the fountains of the deep and the windows of heaven were stopped. The significance of the first 40 days is the lifting of the ark off the earth on the 40th day (7:17). The purpose of the 221 days was to make the earth suitable for life—an apparent replication of the third day of Creation (1:9-13). Grammatically the Hebrew description of continuous motion of the receding waters (8:3) is parallel to the grammar used to describe the raven’s flight to and fro. Large-scale, back and forth motion would have profound effects in shaping the new landscape

Emotional Intelligence Training and Professional Salespeople

Emotional intelligence (EI) has long been considered a significant success factor, especcially in careers like personal selling that involve considerable social. contact (Goldman, 1995). As a result, a series of studies have investigated the link between EI and sales performance. The results of these studies indicates that EI can positively impact sales performanace. As a result, researchers (Deeter-Schmelz & Sojka, 2003) have called for its integration into sales training programs. However, to this point, no research has established an effective approach to EI training in sales. This study begins to rectify that shortcoming by indentifying best practices in general EI training that can be adapted to meet sales training goals. Guidelines to the development of EI training in sales are also provided

Symmetry-breaking Effects for Polariton Condensates in Double-Well Potentials

We study the existence, stability, and dynamics of symmetric and anti-symmetric states of quasi-one-dimensional polariton condensates in double-well potentials, in the presence of nonresonant pumping and nonlinear damping. Some prototypical features of the system, such as the bifurcation of asymmetric solutions, are similar to the Hamiltonian analog of the double-well system considered in the realm of atomic condensates. Nevertheless, there are also some nontrivial differences including, e.g., the unstable nature of both the parent and the daughter branch emerging in the relevant pitchfork bifurcation for slightly larger values of atom numbers. Another interesting feature that does not appear in the atomic condensate case is that the bifurcation for attractive interactions is slightly sub-critical instead of supercritical. These conclusions of the bifurcation analysis are corroborated by direct numerical simulations examining the dynamics of the system in the unstable regime.MICINN (Spain) project FIS2008- 0484

LifeCLEF 2016: Multimedia Life Species Identification Challenges

International audienceUsing multimedia identification tools is considered as one of the most promising solutions to help bridge the taxonomic gap and build accurate knowledge of the identity, the geographic distribution and the evolution of living species. Large and structured communities of nature observers (e.g., iSpot, Xeno-canto, Tela Botanica, etc.) as well as big monitoring equipment have actually started to produce outstanding collections of multimedia records. Unfortunately, the performance of the state-of-the-art analysis techniques on such data is still not well understood and is far from reaching real world requirements. The LifeCLEF lab proposes to evaluate these challenges around 3 tasks related to multimedia information retrieval and fine-grained classification problems in 3 domains. Each task is based on large volumes of real-world data and the measured challenges are defined in collaboration with biologists and environmental stakeholders to reflect realistic usage scenarios. For each task, we report the methodology, the data sets as well as the results and the main outcom

Género, Masculinidad, Feminidad y "Help Seeking" en la Universidad

The current academic performance struggles of college men is gaining increasing research attention (Sax, 2008a, 2008b), but few studies have explored the possible impact of gender-related attributes such as masculinity and femininity on academic help-seeking behaviors and academic performance. In this study of 567 college undergraduates, students who classified themselves as androgynous on the Bem Sex-Role Inventory were more likely to engage in academic help-seeking behaviors than those classified as male sex-typed, female sex-typed, and undifferentiated. No significant differences were found for academic performance. These results highlight the importance of exploring the potential influence of gender-related constructs on academic behavior and performance.Los resultados académicos que están obteniendo los chicos universitarios está siendo una temática que despierta cada vez más el interés de la investigación (Sax, 2008a, 2008b), pero pocos estudios han analizado el posible impacto de los roles de género como la masculinidad y la feminidad en las actitudes ligadas al "help-seeking" académico y a los resultados académicos. En el presente estudio de 567 estudiantes de grado, estudiantes que se clasifican a si mismos como andróginos en el Inventario de roles de género de Bern, están más implicados en el "help-seeking académico que aquellos que están catalogados como hombres o mujeres, e indiferenciados. No se han diferencias respecto a los resultados académicos. Los resultados subrayan la importancia de explorar la influencia potencial de la construcción del género en los resultados y el comportamiento académic

Germline Met Mutations in Mice Reveal Mutation- and Background-Associated Differences in Tumor Profiles

BACKGROUND: The receptor tyrosine kinase Met is involved in the progression and metastasis of numerous human cancers. Although overexpression and autocrine activation of the Met signaling pathway are commonly found in human cancers, mutational activation of Met has been observed in small cell and non-small cell lung cancers, lung adenocarcinomas, renal carcinomas, and mesotheliomas. METHODOLOGY/PRINCIPAL FINDINGS: To investigate the influence of mutationally activated Met in tumorigenesis, we utilized a novel mouse model. Previously, we observed that various Met mutations developed unique mutation-specific tumor spectra on a C57BL/6 background. Here, we assessed the effect of genetic background on the tumorigenic potential of mutationally activated Met. For this purpose, we created congenic knock-in lines of the Met mutations D1226N, M1248T, and Y1228C on the FVB/N background. Consistent with the mutation-specific tumor spectra, several of the mutations were associated with the same tumor types as observed on C57BL/6 background. However, on the FVB/N background most developed a high incidence of mammary carcinomas with diverse histopathologies. CONCLUSIONS/SIGNIFICANCE: This study demonstrates that on two distinct mouse backgrounds, Met is able to initiate tumorigenesis in multiple cell types, including epithelial, hematopoietic, and endothelial. Furthermore, these observations emphasize that even a modest increase in Met activation can initiate tumorigenesis with both the Met mutational spectra and host background having profound influence on the type of tumor generated. Greater insight into the interaction of genetic modifiers and Met signaling will significantly enhance our ability to tailor combination therapies for Met-driven cancers
