Optical cooling of semiconductors has recently been demonstrated both for optically pumped CdS nanobelts and for electrically injected GaInAsSb LEDs at very low powers. To enable cooling at larger power and to understand and overcome the main obstacles in optical cooling of conventional semiconductor structures, we study thermophotonic (TPX) heat transport in cavity coupled light emitters. Our str

Environmental Product Declarations (EPDs) are used to communicate product's environmental performances to relevant stakeholders, whereas Product Category Rules (PCRs) provide guidelines for making EPDs in different product categories. Little is known regarding the cost for developing EPDs and PCRs. We therefore conducted an international survey, and 15 responses from EPD certification operators we

Osteonecrosis of the femoral head is caused by inadequate blood supply to the affected bone. The bone decay process due to lacking blood supply would be likely to be accompanied by the formation of gas-filled pores. We have introduced diode laser absorption spectroscopy to successfully detect water vapor signals from pores in the femoral heads retrieved from hip replacement operations in 19 patien

BACKGROUND: Ischemic preconditioning (IPC) protects the heart from prolonged ischemic insult and reperfusion injury through a poorly understood mechanism. Post-translational modifications of histone residues can confer rapid and drastic switches in gene expression in response to various stimuli, including ischemia. The aim of this study was to investigate the effect of histone methylation in the r

Purpose: A gold standard for evaluation of aesthetic outcome after breast-conserving therapy (BCT) is still lacking. The BCCT.core software has been developed to assess aesthetic result in a standardised way. We aimed to study how the result of BCCT.core after BCT is associated with quality of life, measured with the BREAST-Q™, a validated questionnaire. Methods: Women eligible for BCT were consec

For a collection to be considered as such, and not appear only as a clutter or jumble of things, it has to be based on some kind of selection and systematisation. The research question of this article is how and why collectors structure their collections, organise, and arrange them.

Purpose: Cyclin D1 has a central role in cell cycle control and is an important component of estrogen regulation of cell cycle progression. We have previously shown that high cyclin D expression is related to aggressive features of ER-positive but not ER-negative breast cancer. The aims of the present study were to validate this differential ER-related effect and furthermore explore the relationsh

We used a southern Swedish cohort of psoriasis (PSO) and psoriatic arthritis (PsA) patients and population-based referents (N = 57,800) to investigate the influence of socioeconomic and demographic factors on the probability of healthcare use and on healthcare costs when controlling for need as measured by PSO/PsA and common additional morbidities such as diabetes, depression and myocardial infarc

Objective: Patients with limited metastatic and locally advanced bladder cancer have a poor prognosis, and no definite treatment recommendations exist. However, long-term survival is possible for selected patients if surgery is combined with multiple courses of chemotherapy (i.e. induction chemotherapy). Patients with tumours that are insensitive to chemotherapy probably have little to gain from s

The main thesis of this chapter is that children do not learn single new words but rather new words that belong to the same domain. For example, once they learn a word for a color, other color words will be learned soon after. The chapter presents a model of such domain-oriented language learning. Conceptual spaces are used as a framework for modeling the semantic processes involved in language ac

Background: To investigate the risk of first-time acute coronary syndrome (ACS), stroke and venous thromboembolism (VTE) in patients with ankylosing spondylitis (AS), psoriatic arthritis (PsA) and undifferentiated spondyloarthritis (uSpA), compared to each other and to the general population (GP). Methods: This is a prospective nationwide cohort study. Cohorts with AS (n = 6448), PsA (n = 16,063)

Abstract: Recent developments in radiotherapy have focused on the management of patient motion during treatment. Studies have shown that significant gains in treatment quality can be made by ‘gating’ certain treatments, simultaneously keeping target coverage, and increasing separation to nearby organs at risk (OAR). Motion phantoms can be used to simulate patient breathing motion and provide the m

This research makes clear the narrative transformation in a novel called Red Rebel by Ali Ahmad Bakathir after dealing with a systematic an entrance in which he explains what is meant by narrative transformation and how it is implemented in the text of novels through presenting a number of concepts provided by the narrative semiotics by the School of Paris. The first part of this research shows th
