In this paper we present a technique that improves rendering performance for real-time ith ray in the presence of dynamic lights and objects. In particular we verify photon paths from the previous frame against dynamic objects in the current frame, and show how most photon paths are still valid. When using area lights, we use a data structure to store light distribution that tracks light paths all

Internet är uppbyggt av länkar, vilket är centralt för dess funktion. Samtidigt länkas det i stor omfattning till både olovligt och lovligt upplagt upphovsrättsligt skyddat material. I upphovsrätten är det däremot inte klart när länkning till ett verk kan vara ett upphovsrättsintrång. EU-domstolen kommer dock under 2014 att avgöra tre länkningsmål.

Employees’ Intellectual Property Rights describes and analyses employers’ acquisition of employees’ intellectual property rights in thirty-four different jurisdictions worldwide collectively representing all habitable continents. In today’s knowledge-based global economy, most inventions are made by employed persons through their employers’ research and development activities. However, methods of

A low-profile wideband tri-polarized MIMO antenna is proposed in this paper. Based on characteristic mode analysis of a circular patch, four slots are etched symmetrically on the patch to transform the high-order monopole-like modes into broadside modes with lower resonant frequencies. Four sets of shorting pins are also applied to simultaneously adjust the resonant frequencies of the monopole-lik

By applying Simone de Beauvoir’s philosophy on women as situated embodied subjects and other feminist phenomenological perspectives, I will explore how the Swedish short film Juck (2018) challenges and reframes what it means to screen female bodies and how it in turn contributes to a form of radical feminist (film) practice.

Objective: To determine predictors of change in neuropsychiatric (NP) event status in a large, prospective, international inception cohort of patients with systemic lupus erythematosus (SLE). Methods: Upon enrollment and annually thereafter, NP events attributed to SLE and non-SLE causes and physician-determined resolution were documented. Factors potentially associated with the onset and resoluti

This study aims to understand how goals of activation and gender equality interact in labor market programs directed towards activating unemployed participants. The study draws on interviews with 28 social workers and managers at four Swedish municipally governed labor market programs typically targeted towards poor, unemployed individuals with little to no attachment to the labor market or social

Background: Deep Brain Stimulation (DBS) is an established treatment for motor symptoms in Parkinson's disease (PD). However, side effects often limit the usefulness of the treatment. New method: To mitigate this problem, we developed a novel cluster of ultrathin platinum-iridium microelectrodes (n = 16) embedded in a needle shaped gelatin vehicle. In an established rodent PD-model (6-OHDA unilate

• Climate finance coordination challenges reflect political differences, including divergent interests among ministries involved in the governance of multilateral climate funds.• Differences in the histories and governance of the Climate Investment Funds (CIF) and Green Climate Fund (GCF) – two key multilateral climate funds – shape debate on their respective advantages and future roles.• The mult

Recent progress in the field of human induced pluripotent stem cells (iPSCs) has led to the efficient production of human neuronal cell models for in vitro study. This has the potential to enable the understanding of live human cellular and network function which is otherwise not possible. However, a major challenge is the generation of reproducible neural networks together with the ability to int

The EPOCH Measure of Adolescent Well-being measures five positive indicators of the well-being of adolescents: engagement, perseverance, optimism, connectedness and happiness. This five-factor structure along with other indicators of validity and reliability were supported for the original English version and the Chinese version. In this study, we tested the psychometric properties of the Swedish

The present invention relates to the synthesis of a beaded and cross-linked, high loading capacity polymer for solid phase synthesis, purification of reaction mixtures, chromatographic separation procedures, and the like. The invention can thus be used for the isolation of molecular entities having an affinity for the polymer beads or a chemical entity attached thereto. The beaded polymer matrix c

Objectives: To analyse the living conditions and social outcomes (housing, engagement in employment or higher education, access to personal assistance and having a partner) in adults with cerebral palsy (CP) relative to their age, sex, communication ability, and motor skills. Methods: Cross-sectional registry-based study of 1,888 adults (1,030 males/858 females) with CP in the Swedish CP follow-up

PURPOSE OF REVIEW: Statistical models of shape and appearance have increased their popularity since the 1990s and are today highly prevalent in the field of medical image analysis. In this article, we review the recent literature about how statistical models have been applied in the context of osteoporosis and fracture risk estimation.RECENT FINDINGS: Recent developments have increased their abili

Auguste Comte var inflytelserik i stora delar av världen under 1800- talet och hans bidrag till sociologin är större än vad som i dag vanligen erkänns. Han var den förste som samtidigt tog samhället som studie- objekt och krävde systematiska empiriska studier av sociala fenomen. Influerad av dåtidens naturvetenskapliga syn på objektivitet, rationa- lism, orsak och verkan introducerade han idén om

The current study aimed to estimate the effective doses and conversion coefficients (CCs) for typical barium swallow (BS), barium meal (BM) and barium enema (BE) protocols and to evaluate the impact of different examination parameters on the resulting CCs. Data were collected in surgical and therapy departments in St. Petersburg Urban Mariinsky Hospital. Computational models were developed using P

Some of the ethically most sensitive issues in radiation protection arise at imaging of pregnant - and potentially pregnant - patients and of newborn. This article reviews the current literature and recommendations on imaging during pregnancy and breastfeeding. Risks related to alternative non-ionizing radiation methods are also considered. With few exceptions, exposure of the fetus through radiog
