STRUCTURE AND FUNCTION Age-Related Changes in Myocardial Relaxation Using Three-Dimensional Tagged Magnetic Resonance Imaging

Purpose. Marked changes in left ventricular diastolic filling occur with advancing age, but alterations in myocardial movement accompanying these findings have not been previously documented. We aimed to identify differences in myocardial motion during relaxation and diastole using magnetic resonance imaging (MRI), with tagging, which uniquely allows accurate, noninvasive assessment of myocardial movement in three dimensions. Methods. Tagged MRI images from two groups of normal individuals were analyzed using dedicated computer software to provide values for group comparison of apical rotation, torsion, and circumferential and longitudinal strain throughout the cardiac cycle. Results. The mean age of the younger group was 22 years, ðn 1⁄4 15Þ and that of the older group was 69 years, ðn 1⁄4 16Þ: In the older group, peak apical rotation and torsion were increased during systole and significantly more apical rotation, torsion, circumferential, and longitudinal strain persisted during myocardial relaxation and diastole. In addition, peak normalized reversal of apical rotation was reduced (25:1 ^ 1:28 s vs. 26:7 ^ 1:28 s; p 1⁄4 0:001), and there were slower peak rates of circumferential lengthening (76:2 ^ 28% s vs. 142:5 ^ 17% s, p , 0:001) and longitudinal lengthening (62:7 ^ 21% s vs. 122:5 ^ 20% s, p , 0:001). Conclusions. Tagged MRI is a unique, noninvasive imaging method that can identify significant prolongation and reduction of myocardial relaxation in older compared with young normal individuals.

StatCache: a probabilistic approach to efficient and accurate data locality analysis

The widening memory gap reduces performance of applications with poor data locality. Therefore, there is a need for methods to analyze data locality and help application optimization. In this paper we present StatCache, a novel sampling-based method for performing data-locality analysis on realistic workloads. StatCache is based on a probabilistic model of the cache, rather than a functional cache simulator. It uses statistics from a single run to accurately estimate miss ratios of fully-associative caches of arbitrary sizes and generate working-set graphs. We evaluate StatCache using the SPEC CPU2000 benchmarks and show that StatCache gives accurate results with a sampling rate as low as 10/sup -4/. We also provide a proof-of-concept implementation, and discuss potentially very fast implementation alternatives.
Charge transport in TiO2/MEH-PPV polymer photovoltaics

We study the effect of polymer thickness, hole mobility, and morphology on the device properties of polymer-based photovoltaics consisting of MEH-PPV as the optically active layer, TiO 2 as the exciton dissociation surface, and ITO and Au electrodes. We demonstrate that the conversion efficiency in these polymerbased photovoltaics is primarily limited by the short exciton diffusion length combined with a low carrier mobility. For MEH-PPV devices with optimal device geometry, we achieve quantum efficiencies of 6% at the maximum absorption of the polymer, open circuit voltages of 1.1 V, current densities of 0.4 mA/cm 2 and rectification ratios greater than 10 5 under 100 mW/cm white light illumination. In addition, we achieve fill factors up to 42% at high light intensities and as high as 69% at low light intensities. We conclude by presenting a model that describes charge transport in solid-state polymer/TiO 2-based photovoltaics and suggest methods for improving energy conversion efficiencies in polymer-based photovoltaics.
Learning Bayesian Network structures using Multiple Offspring Sampling

Variable Ordering (VO) plays an important role when inducing Bayesian Networks (BNs). Previous works in the literature suggest that it is worth pursuing the use of evolutionary strategies for identifying a suitable VO, when learning a Bayesian Network structure from data. This paper proposes a hybrid adaptive algorithm named VOMOS (Variable Ordering Multiple Offspring Sampling) where the new individuals are created using a set of recombination operators (crossover and mutation operators). Experiments performed in datasets revealed that the VOMOS approach is promising and tends to generate consistent and representative BNs.
Using RFID Snapshots for Mobile Robot Self-Localization

(cid:151)In recent years, radio frequency identi(cid:2)cation (RFID) has found its way into the (cid:2)eld of mobile robot navigation. On the one hand, the technology promises to contribute solutions to common problems in self-localization and mapping such as the data association problem. On the other hand, questions like how to cope with poor or even missing range and bearing information remain open. In this paper, we present a novel method which tackles these challenges: Inspired by vision-based self-localization approaches, it utilizes RFID snapshots for the estimation of the robot pose. Our experiments show that the new technique enables a robot to successfully localize itself in an indoor environment. The accuracy is comparable to the one of a previous approach using an explicit model of detection probabilities. Our method, however, requires fewer iterations of the underlying particle (cid:2)lter in order to converge to the approximate robot pose.
Peat erosion: processes, patterns and rates

Improved understanding of peat erosion processes and rates of erosion at different scales are urgently needed to better predict future peat erosion under climate and land management changes. This laboratory and field study on UK blanket peat showed that both raindrop impact and the interaction between rainfall and flow driven erosion processes were important in affecting peat overland flow and erosion processes for gentle slopes and shallow overland flow conditions. Raindrop impact contributed significantly to increasing sediment yields (47%). Needle-ice (NI) processes dramatically increased peat erodibility and reduced peat stability, producing six times higher peat losses than control treatments. NI significantly reduced surface flow velocity (32–44%) but increased overland flow shear stress (55–85%). Net topographic change measured using Structure-from-Motion (SfM) was –14 to +30 mm yr–1 for field plots (peat hagg, gully wall, riparian area, gully head) and –27 mm yr–1 over a 598 m2 catchment. Repeated SfM surveys showed spatial patterns of erosion and deposition could be driven by event-scale processes that may not be observed with surveys conducted between long intervals. Surface roughness was a significant predictor of topographic change at both field plot scale and laboratory macroscale. SfM produced significantly different topographic change values compared to sediment traps in nested catchments in the field and sediment yield sampling on laboratory peat blocks. The greatest sediment and particulate organic carbon losses from a 1.7 ha study catchment were found during the autumn and much of the available sediment appeared to be derived from weathering during dry weather earlier in the year. The research shows that where bare peat is subject to weathering by needle ice and desiccation, and is subsequently splashed by raindrops a large supply of sediment can be mobilised by overland flow, particularly where flow concentrates producing interrill, rill and gully erosion.
Technology Acceptance Model for Complex Technologies in a Period of Rapid Catching-Up

Technology Acceptance Model (TAM) was developed to explain computer usage behaviour. This concept later found applications in studying adoption of consumer products like Cellular phones. In this paper an attempt has been made to understand the importance of user motivations and perceptions in determining his behaviour to use indigenous technology using the TAM concept. Cases of new product technologies that were developed by Indian firms with R&D grants from the government under PATSER scheme of DSIR were examined. These products were developed by commercial organisations with an intent to profit from the development. However, despite their closeness to market, their experience with user adoption of these technologies is mixed, some were accepted with excitement and some others are struggling to find acceptance from the targeted users. Examinations of various factors indicate prior experience in handling innovations and purchase practices to have significant effects on user's extrinsic and intrinsic motivations.
From Perception to Sentence Comprehension: The Convergence of Auditory and Visual Information of Language in the Left Inferior Frontal Cortex

We used functional magnetic resonance imaging (fMRI) to characterize cortical activation associated with sentence processing, thereby elucidating where in the brain auditory and visual inputs of words converge during sentence comprehension. Within one scanning session, subjects performed three types of tasks with different linguistic components from perception to sentence comprehension: nonword (N(AV); auditory and visual), phrase (P; either auditory or visual), and sentence (S; either auditory or visual) tasks. In a comparison of the P and N(AV) tasks, the angular and supramarginal gyri showed bilateral activation, whereas the inferior and middle frontal gyri showed left-lateralized activation. A comparison of the S and P tasks, together with a conjunction analysis, revealed a ventral region of the left inferior frontal gyrus (F3t/F3O), which was sentence-processing selective and modality-independent. These results unequivocally demonstrated that the left F3t/F3O is involved in the selection and integration of semantic information that are separable from lexico-semantic processing.
Physician use of electronic medical records: Issues and successes with direct data entry and physician productivity

At Intermountain Health Care, we evaluated whether physicians in an ambulatory setting will voluntarily choose to enter data directly into an electronic health record (EHR). In this paper we describe the benefits of an EHR, as they exist in the current IHC application and the ways in which we have sought to minimize obstacles to physician data entry. Currently, of 472 IHC employed physicians, 321 (68%) routinely enter some data directly into the EHR without coercion. Twenty-five percent (80/321) of the physicians use voice recognition for some data entry. Twelve of our 95 ambulatory clinics have voluntarily adopted measures to eliminate paper charts. Of the 212 physicians who entered data in 2004, sixty-nine physicians (22%) increased their level of data entry, while 12 (6%) decreased. We conclude that physicians will voluntarily adopt an EHR system, and will continue and even increase use after implementation barriers are addressed.
The Common Factor in Idiosyncratic Volatility: Quantitative Asset Pricing Implications

We show that firms׳ idiosyncratic volatility obeys a strong factor structure and that shocks to the common idiosyncratic volatility (CIV) factor are priced. Stocks in the lowest CIV-beta quintile earn average returns 5.4% per year higher than those in the highest quintile. The CIV factor helps to explain a number of asset pricing anomalies. We provide new evidence linking the CIV factor to income risk faced by households. Our findings are consistent with an incomplete markets heterogeneous agent model. In the model, CIV is a priced state variable because an increase in idiosyncratic firm volatility raises the average household׳s marginal utility. The calibrated model matches the high degree of co-movement in idiosyncratic volatilities, the CIV-beta return spread, and several other asset price moments.
Raw Power: Punk, DIY and Underground Cultures as Spaces of Resistance in Contemporary Portugal

This article focuses on presenting, analysing and understanding the ‘do-it-yourself’ (DIY) representations of over 200 participants in Portuguese punk music scenes between 1977 and 2014. Through an ethnographic study of punk and the DIY ethos in Portugal, the article depicts its local interpretation and significance, and highlights the singularities of this socio-historical context. Our approach has three focal points: (1) the importance of DIY punk manifestations in the development of youth (sub)cultures, including forms of production and consumption of music, fashion, aesthetics, leisure, the night and cosmopolitanism; (2) the singularity of DIY punk manifestations in Portugal and related resistance practices in their correlation with social, political and economic development in a country outside the Anglo-Saxon context; and (3) the embedding of a DIY ethos and the associated claim to authenticity in the professions and careers in which punks engage today.
Camera, Intervention and Cultural Critique: An Introduction

The key questions of the research project Camera as Cultural Critique, in which all contributors to this section of the issue participated, are outlined here. The overall purpose of the project was to explore how the use of audiovisual media in ethnographic research may contribute to sustained cultural critique. Grounding that critique in a certain understanding of the temporality of the present—as always in a state of emergence and involving images of past and future—the researchers explore the potential of audiovisual media for the critical (re)imagining of pasts and futures, in creative collaborations with their interlocutors. To create platforms for such collaboration different interventionist methods are used, including video feedback, the use of film archives in provocative museum installations, and the use of photo archives in intercultural dialogue and collaborative re-enactment. Another focus of attention is the particular affordances of the camera as technology. Here we explore the resistance that the camera, as a mechanical eye, exerts on the filmmakers’ intentions, thus prompting reflection on ways of seeing. The camera can also act as a mediator between people and their different ways of perceiving. Finally, we see the camera as a context-triggering device that can unsettle deep-seated cultural ways of seeing and understanding. In short, we conclude that audiovisual media have great potential for a cultural-critical and collaborative research practice.
The evolution of subject-verb agreement in Eastern Tukanoan

This article describes the evolution of past/perfective subject-verb agreement morphology in the Tukanoan family, reconstructing relevant aspects of Proto-Tukanoan verbal morphology and delineating the subsequent diachronic development of verbal subject agreement morphology in the Eastern branch of the family. We argue that suffixes that cumulatively expone past/perfective and person, number, and gender (png) subject agreement resulted from the fusion of post-verbal demonstratives/pronouns expressing png information with suffixes expressing past/perfective tam information. We propose that different png agreement categories developed at successive stages in the diversification of the family, with third person masculine singular subject agreement emerging before other png categories, followed by animate plural agreement, then finally by the development of third person feminine agreement. The result in Eastern Tukanoan was a cross-linguistically unusual agreement system that contrasts four agreement categories: (i) first and second person singular and third person inanimate (singular and plural); (ii) third person animate masculine singular; (iii) third person animate feminine singular; and (iv) third animate plural.
The Moral Gatekeeper? Moderation and Deletion of User-Generated Content in a Leading News Forum

Participatory formats in online journalism offer increased options for user comments to reach a mass audience, also enabling the spreading of incivility. As a result, journalists feel the need to moderate offensive user comments in order to prevent the derailment of discussion threads. However, little is known about the principles on which forum moderation is based. The current study aims to fill this void by examining 673,361 user comments (including all incoming and rejected comments) of the largest newspaper forum in Germany (Spiegel Online) in terms of the moderation decision, the topic addressed, and the use of insulting language using automated content analysis. The analyses revealed that the deletion of user comments is a frequently used moderation strategy. Overall, more than one-third of comments studied were rejected. Further, users mostly engaged with political topics. The usage of swear words was not a reason to block a comment, except when offenses were used in connection with politically sensitive topics. We discuss the results in light of the necessity for journalists to establish consistent and transparent moderation strategies.
Respuesta fisiológica, neuromuscular y biomecánica al entrenamiento intermitente de alta intensidad en atletas de fondo

espanolEl objetivo general de esta Tesis Doctoral fue determinar desde una perspectiva multidisciplinar (fisiologica, neuromuscular y biomecanica) el efecto agudo de diferentes sesiones de entrenamiento intermitente de alta intensidad (HIIT) para atletas de fondo, ademas de comprobar su eficacia como parte de un programa de entrenamiento. Para ello se elaboraron nueve articulos: i) Revision sistematica, ii) Tres articulos determinando la respuesta a un HIIT tipico para estos atletas, iii) Tres comparando el efecto de un HIIT tradicional versus una nueva propuesta, iv) Dos sobre un programa de intervencion basado en HIIT. Los resultados ponen de manifiesto la importancia de este medio de entrenamiento (HIIT) para el atleta de resistencia, posibilitando una reduccion del kilometraje semanal (motivo frecuente de lesion) al mismo tiempo que un incremento de la intensidad promedio de cada sesion (fuertemente asociado al rendimiento), y todo ello, sin deteriorar la respuesta neuromuscular del atleta ni la cinematica de carrera. EnglishThe main objective of this PhD Thesis was to determine from a multidisciplinary perspective (physiological, neuromuscular and biomechanical) the acute effect of different high-intensity intermittent training (HIIT) protocols in endurance athletes and, to determine its effectiveness as a HIIT-based training programme. Nine papers were written: i) A systematic review, ii) Three about the acute effect of a typical HIIT protocol for these athletes, iii) Three about the comparison between that typical HIIT and a new HIIT protocol; iv) Two about a HIIT-based training programme. These findings highlight the importance of HIIT as a training method for endurance runners that leads to a reduction in weekly running distances (risk factor for lower extremity running injuries) and an increase in mean running intensity (deeply associated to running performance) without impairing the neuromuscular performance nor running kinematic characteristics.
An Averaging Principle for Combined Interaction Graphs - Connectivity and Applications to Genetic Switches

Time-continuous dynamical systems defined on graphs are often used to model complex systems with many interacting components in a non-spatial context. In the reverse sense attaching meaningful dynamics to given "interaction diagrams" is a central bottleneck problem in many application areas, especially in cell biology where various such diagrams with different conventions describing molecular regulation are presently in use. In most situations these diagrams can only be interpreted by the use of both discrete and continuous variables during the modelling process, corresponding to both deterministic and stochastic hybrid dynamics. The conventions in genetics are well known, and therefore we use this field for illustration purposes. In [25] and [26] the authors showed that with the help of a multi-scale analysis stochastic systems with both continuous variables and finite state spaces can be approximated by dynamical systems whose leading order time evolution is given by a combination of ordinary differential equations (ODEs) and Markov chains. The leading order term in these dynamical systems is called average dynamics and turns out to be an adequate concept to analyze a class of simplified hybrid systems. Once the dynamics is defined the mutual interaction of both ODEs and Markov chains can be analyzed through the (reverse) introduction of the so-called Interaction Graph, a concept originally invented for time-continuous dynamical systems, see [5]. Here we transfer this graph concept to the average dynamics, which itself is introduced as a heuristic tool to construct models of reaction or contact networks. The graphical concepts introduced form the basis for any subsequent study of the qualitative properties of hybrid models in terms of connectivity and (feedback) loop formation.
