A performance and energy evaluation of many-light rendering algorithms

Recently, the performance of many-light algorithms, where thousands of light sources are used to compute the lighting in a scene, has improved so much that they have reached the realm of real-time rendering. In general, the algorithm that is considered “best” is the one that is the fastest in terms of time per frame. Given that power efficiency may become or already is one of the most important op

Frontotemporal dementia - symptoms and brain pathology

Popular Abstract in Swedish Frontotemporal demens (FTD) är en grupp av demenssjukdomar som främst drabbar hjärnans pannlober och främre tinninglober. Gemensamt för FTD-sjukdomarna är en fortskridande nervcellsförlust och förtvining av framför allt hjärnbarken. Sjukdomen medför personlighetsförändring med beteendestörningar, förändringar i känsloliv och kognitiva svårigheter. En försämring av språkFrontotemporal dementia (FTD) is the clinical term for a heterogeneous group of dementia disorders with symptoms emerging from frontotemporal lobar degeneration (FTLD). FTD encompasses the behavioural variant (bvFTD) and the progressive aphasias: progressive non-fluent aphasia (PNFA) and semantic dementia (SD). Neuropathological classification is based on protein pathology with three major subgrou

Uniform Bounds on the Relative Error in the Approximation of Upper Quantiles for Sums of Arbitrary Independent Random Variables

Fix any n≥1. Let X~1,…,X~n be independent random variables. For each 1≤j≤n, X~j is transformed in a canonical manner into a random variable Xj. The Xj inherit independence from the X~j. Let sy and s∗y denote the upper 1y th −−− quantile of Sn=∑nj=1Xj and S∗n=sup1≤k≤nSk, respectively. We construct a computable quantity Q−−y based on the marginal distributions of X1,…,Xn to produce upper and lower b

Institutional Conditions and Innovation Systems: On the Impact of Regional Policy on Firms in Different Sectors.

Moodysson J. and Zukauskaite E. Institutional conditions and innovation systems: on the impact of regional policy on firms in different sectors, Regional Studies. This paper deals with institutional conditions in regional innovation systems: how institutions affect the organization of innovation activities among firms; and in what ways regional policy initiatives can be supportive. The analysis dr

Clinical Examinations of the Rectoanal Inhibitory Reflex Correlated with Anography Findings, Histopathological Findings, and Clinical Outcomes

The diagnostic method for Hirschsprung’s disease (HD) involves rectal biopsy to determine the presence of histopathological findings for aganglionosis. Contrast enema (CE) and anorectal manometry help to support the indication for biopsies. Patients with HD lack a rectoanal inhibitory reflex (RAIR) that can be studied using manometry, ultrasound, or a modified contrast enema (CE), which provoke

Green IT in Practice: Virtual Meetings in Swedish Public Agencies

This paper presents and discusses how virtual meetings (VMs) can be used as a Green IT-measure in an organization, by analyzing the experiences and results from the project ‘REMM’ involving 20 public agencies in Sweden. The paper describes the methodology used in the REMM project, how progress and results have been monitored, evaluating how well the approach has worked out and discussing how appli

The challenges of integrating oxidative stress into life history biology.

It has been proposed that the molecular and physiological systems that regulate biological functions impose costs and constraints that are fundamental to the understanding of variation in life histories. In particular, studies of oxidative stress emphasize how evolutionary contingency can impose novel trade-offs for organisms, and how this may create or eliminate functional linkages between traits

Effects of lifestyle factors on concentrations of salivary cortisol in healthy individuals

Objective . Salivary cortisol is widely used in occupational health research. However, many ordinary daily activities can influence the concentrations of cortisol and the interpretation of field studies. The aim of the present study was to evaluate the effect of lifestyle factors on salivary cortisol in everyday settings. Material and methods . Healthy employees participated in one or more sub-stu

EULAR recommendations for the use of imaging of the joints in the clinical management of rheumatoid arthritis

Objective To develop evidence-based recommendations on the use of imaging of the joints in the clinical management of rheumatoid arthritis (RA). Methods The task force comprised an expert group of rheumatologists, radiologists, methodologists and experienced rheumatology practitioners from 13 countries. Thirteen key questions on the role of imaging in RA were generated using a process of discussio

A low band cellular terminal antenna impedance tuner in 130nm CMOS-SOI technology

This paper presents a low band antenna impedance tuner in 130nm CMOS-SOI technology. It consists of three digitally controlled switched capacitor banks and two off-chip inductors and is intended for use in terminals supporting modern cellular standards like WCDMA and LTE. By using a negative gate bias in the off state, linearity can be improved and maintained. Measurements show an OIP3 exceeding +

Electronic structure changes in cobalt phthalocyanine due to nanotube encapsulation probed using resonant inelastic X-ray scattering

The electronic structure of cobalt phthalocyanine (CoPc) changes upon encapsulation inside multi-walled carbon nanotubes (CoPc@MWNT), as detected in this research using Co-K-edge X-ray absorption near-edge structure spectroscopy (XANES) and Co-K alpha(1) resonant inelastic X-ray scattering (RIXS). The CoPc molecules are no longer planar once inside the nanotubes, and the molecular symmetry is foun

Historical land-use and landscape change in southern Sweden and implications for present and future biodiversity

The two major aims of this study are (1) To test the performance of the Landscape Reconstruction Algorithm (LRA) to quantify past landscape changes using historical maps and related written sources, and (2) to use the LRA and map reconstructions for a better understanding of the origin of landscape diversity and the recent loss of species diversity. Southern Sweden, hemiboreal vegetation zone. The

Single and multi-user cooperative MIMO in a measured urban macrocellular environment

We study the potential benefits of cooperative multiple-input multiple-output signaling from multiple coherent base stations with one or more mobile stations in an urban macrocellular environment at 2.66 GHz. The analysis uses fully-coherent measurements of the channel from three base stations to a single mobile station equipped with four antennas. The observed channels are used to explore the gai
