Studies of resistance switching effects in metal/YBa2Cu3O7-x interface junctions

Current-voltage characteristics of planar junctions formed by an epitaxial c-axis oriented YBa2Cu3O7-x thin film micro-bridge and Ag counter-electrode were measured in the temperature range from 4.2 K to 300 K. A hysteretic behavior related to switching of the junction resistance from a high-resistive to a low-resistive state and vice-versa was observed and analyzed in terms of the maximal current bias and temperature dependence. The same effects were observed on a sub-micrometer scale YBa2Cu3O7-x thin film - PtIr point contact junctions using Scanning Tunneling Microscope. These phenomena are discussed within a diffusion model, describing an oxygen vacancy drift in YBa2Cu3O7-x films in the nano-scale vicinity of the junction interface under applied electrical fields.Comment: To be published in Applied Surface Science

Landscape Values and Aesthetic Preferences Across the Front Range

Boulder’s Open Space and Mountain Parks (OSMP) lands are managed to provide a diverse set of benefits valued by Boulder’s residents as well as tourists. Not all OSMP lands provide the same set of benefits however. Understanding how the values associated with OSMP lands vary across the region can provide managers with insights into how best to allocate resources so that they yield the maximum public benefit. In addition to an understanding of the values visitors associate with OSMP lands, management can benefit from knowledge of how different features of the landscape impact user experiences, both positively and negatively

Aesthetic Characteristics of the Front Range: An Analysis of Viewsheds Provided by Boulder OSMP Lands

The city of Boulder’s Open Space and Mountain Parks (OSMP) lands offer residents and visitors a variety of unique recreational, scenic, and cultural experiences that are often captured and shared publicly via social media. Given the diversity of OSMP lands, visitor experiences likely differ based on the aesthetic and biophysical features that can be viewed from these landscapes. For instance, the peaks of the iconic Flatirons provide visitors with different scenic views than the low-lying grasslands in the southeastern area of the city. Furthermore, visitor use and enjoyment of OSMP lands could be directly related to the landscape features that are visible from these different locations. Understanding how visible landscape features vary across OSMP lands can help managers target their planning efforts to improve the quality of outdoor recreation experiences, and potentially identify new locations for outdoor recreation infrastructure (e.g., trails, pavilions, etc.) that offer the ability to see the regions most desirable landscape features. This study: (1) identifies points in the landscape where users are often inspired to take photographs; (2) maps the landscapes most often viewed by visitors; (3) summarizes the types of landscape features viewed from OSMP lands; and (4) determines how these landscape features vary across LCAs

Microwave observations of spinning dust emission in NGC6946

We report new cm-wave measurements at five frequencies between 15 and 18GHz of the continuum emission from the reportedly anomalous "region 4" of the nearby galaxy NGC6946. We find that the emission in this frequency range is significantly in excess of that measured at 8.5GHz, but has a spectrum from 15-18GHz consistent with optically thin free-free emission from a compact HII region. In combination with previously published data we fit four emission models containing different continuum components using the Bayesian spectrum analysis package radiospec. These fits show that, in combination with data at other frequencies, a model with a spinning dust component is slightly preferred to those that possess better-established emission mechanisms.Comment: submitted MNRA

A review of the methodological features of systematic reviews in maternal medicine

Background In maternal medicine, research evidence is scattered making it difficult to access information for clinical decision making. Systematic reviews of good methodological quality are essential to provide valid inferences and to produce usable evidence summaries to guide management. This review assesses the methodological features of existing systematic reviews in maternal medicine, comparing Cochrane and non-Cochrane reviews in maternal medicine. Methods Medline, Embase, Database of Reviews of Effectiveness (DARE) and Cochrane Database of Systematic Reviews (CDSR) were searched for relevant reviews published between 2001 and 2006. We selected those reviews in which a minimum of two databases were searched and the primary outcome was related to the maternal condition. The selected reviews were assessed for information on framing of question, literature search and methods of review. Results Out of 2846 citations, 68 reviews were selected. Among these, 39 (57%) were Cochrane reviews. Most of the reviews (50/68, 74%) evaluated therapeutic interventions. Overall, 54/68 (79%) addressed a focussed question. Although 64/68 (94%) reviews had a detailed search description, only 17/68 (25%) searched without language restriction. 32/68 (47%) attempted to include unpublished data and 11/68 (16%) assessed for the risk of missing studies quantitatively. The reviews had deficiencies in the assessment of validity of studies and exploration for heterogeneity. When compared to Cochrane reviews, other reviews were significantly inferior in specifying questions (OR 20.3, 95% CI 1.1–381.3, p = 0.04), framing focussed questions (OR 30.9, 95% CI 3.7- 256.2, p = 0.001), use of unpublished data (OR 5.6, 95% CI 1.9–16.4, p = 0.002), assessment for heterogeneity (OR 38.1, 95%CI 2.1, 688.2, p = 0.01) and use of meta-analyses (OR 3.7, 95% CI 1.3–10.8, p = 0.02). Conclusion This study identifies areas which have a strong influence on maternal morbidity and mortality but lack good quality systematic reviews. Overall quality of the existing systematic reviews was variable. Cochrane reviews were of better quality as compared to other reviews. There is a need for good quality systematic reviews to inform practice in maternal medicine
