TL;DR: In this paper, an update of a Cochrane Review first published in 2005 is presented, where surgeons are used to treat persistent pain and dysfunction at the base of the thumb when conservative management such as splinting, or medical management, such as oral analgesics, is no longer adequate in reducing disability and pain.
Abstract: Background Surgery is used to treat persistent pain and dysfunction at the base of the thumb when conservative management, such as splinting, or medical management, such as oral analgesics, is no longer adequate in reducing disability and pain. This is an update of a Cochrane Review first published in 2005.

TL;DR: An intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment experiments at Duke University and Oak Ridge National Laboratory yields a framework for analysing and interpreting model predictions of transpiration responses to eCO2, and highlights key improvements to these types of models.
Abstract: Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed model structures to identify the key underlying assumptions causing differences in model predictions of transpiration and canopy water use efficiency. We then compared the models against data to identify model assumptions that are incorrect or are large sources of uncertainty. We found that model-to-model and model-to-observations differences resulted from four key sets of assumptions, namely (i) the nature of the stomatal response to elevated CO2 (coupling between photosynthesis and stomata was supported by the data); (ii) the roles of the leaf and atmospheric boundary layer (models which assumed multiple conductance terms in series predicted more decoupled fluxes than observed at the broadleaf site); (iii) the treatment of canopy interception (large intermodel variability, 2–15%); and (iv) the impact of soil moisture stress (process uncertainty in how models limit carbon and water fluxes during moisture stress). Overall, model predictions of the CO2 effect on WUE were reasonable (intermodel l = approximately 28% � 10%) compared to the observations (l = approximately 30% � 13%) at the well-coupled coniferous site (Duke), but poor (intermodel l = approximately 24% � 6%; observations l = approximately 38% � 7%) at the broadleaf site (Oak Ridge). The study yields a framework for analysing and interpreting model predictions of transpiration responses to eCO2, and highlights key improvements to these types of models.

TL;DR: In this paper, the authors explore theories, discourses, and experiences of globalization, drawing on perspectives from history, anthropology, cultural and literary studies, geography, political economy, and sociology.
Abstract: COURSE DESCRIPTION In popular and scholarly discourse, the term \"globalization\" is widely used to put a name to the shape of the contemporary world. In the realms of advertising, a variety of media, policymaking, politics, academia, and everyday talk, \"globalization\" references the sense that we now live in a deeply and everincreasingly interconnected, mobile, and speeded-up world that is unprecedented, fueled by technological innovations and geopolitical and economic transformations. Drawing on perspectives from history, anthropology, cultural and literary studies, geography, political economy, and sociology, this course will explore theories, discourses, and experiences of globalization.

TL;DR: A new global database of Rdark and associated leaf traits is analyzed and values at any given Vcmax or leaf nitrogen concentration were higher in herbs than in woody plants, and variation in Rdark among species and across global gradients in T and aridity is highlighted.
Abstract: Leaf dark respiration (R-dark) is an important yet poorly quantified component of the global carbon cycle. Given this, we analyzed a new global database of R-dark and associated leaf traits. Data for 899 species were compiled from 100 sites (from the Arctic to the tropics). Several woody and nonwoody plant functional types (PFTs) were represented. Mixed-effects models were used to disentangle sources of variation in R-dark. Area-based R-dark at the prevailing average daily growth temperature (T) of each siteincreased only twofold from the Arctic to the tropics, despite a 20 degrees C increase in growing T (8-28 degrees C). By contrast, R-dark at a standard T (25 degrees C, R-dark(25)) was threefold higher in the Arctic than in the tropics, and twofold higher at arid than at mesic sites. Species and PFTs at cold sites exhibited higher R-dark(25) at a given photosynthetic capacity (V-cmax(25)) or leaf nitrogen concentration ([N]) than species at warmer sites. R-dark(25) values at any given V-cmax(25) or [N] were higher in herbs than in woody plants. The results highlight variation in R-dark among species and across global gradients in T and aridity. In addition to their ecological significance, the results provide a framework for improving representation of R-dark in terrestrial biosphere models (TBMs) and associated land-surface components of Earth system models (ESMs).

TL;DR: This paper provides as a guide and quick reference for researchers and practicing engineers in deciding which control and modulation method to consider for an application in a given topology at a certain power level, switching frequency and demanded dynamic response.
Abstract: Impedance-source networks cover the entire spectrum of electric power conversion applications (dc-dc, dc-ac, ac-dc, ac-ac) controlled and modulated by different modulation strategies to generate the desired dc or ac voltage and current at the output. A comprehensive review of various impedance-source-network-based power converters has been covered in a previous paper and main topologies were discussed from an application point of view. Now Part II provides a comprehensive review of the most popular control and modulation strategies for impedance-source network-based power converters/inverters. These methods are compared in terms of theoretical complexity and performance, when applied to the respective switching topologies. Further, this paper provides as a guide and quick reference for researchers and practicing engineers in deciding which control and modulation method to consider for an application in a given topology at a certain power level, switching frequency and demanded dynamic response.
