Optical sensors operating in the infrared range of the electromagnetic spectrum are key components in a variety ofapplications including optical communication, night vision, medical diagnosis, surveillance, and astronomy.Semiconductor nanowires have great potential for realizing broadband infrared photodetectors with excellentresponsivity, low dark current and low noise, and a unique compatibility
Studien undersöker vad biblioteksanvändare gör i de meröppna stadsdelsbiblioteken i Lunds kommun samt utforskar vad användarna skulle vilja göra i de meröppna biblioteken.
There has been an abundance of research discussing the health implications of generalised trust and happiness over the past two decades. Both attitudes have been touted as independent predictors of morbidity and mortality, with strikingly similar trajectories and biological pathways being hypothesised. To date, however, neither trust nor happiness have been considered simultaneously as predictors
Polymerase chain reaction (PCR) detection has become the gold standard for diagnosis and typing of enterovirus (EV) and human parechovirus (HPeV) infections. Its effectiveness depends critically on using the appropriate sample types and high assay sensitivity as viral loads in cerebrospinal fluid samples from meningitis and sepsis clinical presentation can be extremely low. This study evaluated th
The U antigen (MNS5) is one of 49 antigens belonging to the MNS blood group system (ISBT002) carried on glycophorins A (GPA) and B (GPB). U is present on the red blood cells in almost all Europeans and Asians but absent in approximately 1.0% of Black Africans. U negativity coincides with negativity for S (MNS3) and s (MNS4) on GPB, thus be called S-s-U-, and is thought to arise from homozygous del
Natural resources can have a powerful impact on the public budget but may also hinder the development of other sources of revenue, thus limiting the long-term development of fiscal capacity in resource-rich countries. This article evaluates both possible effects bycomparing the long-term evolution (1850s-1930s) of public revenues in Andean (Bolivia,Chile and Peru) and Nordic (Norway and Sweden) co
The hot water circulation system in a building is a system which helps prevent Legionella problems whilst ensuring that tenants have access to hot water quickly. Poorly designed or implemented systems not only increase the risk to people’s health and thermal comfort, but even result in an increase in the energy needed for this system to function properly. Results from previous studies showed that The hot water circulation system in a building is a system which helps prevent Legionella problems whilst ensuring that tenants have access to hot water quickly.

An analytic expression for the composition of a ternary solid material nucleating from a quaternary liquid melt has been derived. This theory has been applied to Au-catalyzed and self-catalyzed, nucleation limited VLS growth of ternary III-V nanowires. Next, the developed model has been applied for the description of the composition dependence of the ZB/WZ polytypism in ternary nanowires.
Ultrasound optical tomography (UOT) is an imaging technique based on the acousto-optic effect that can perform optical imaging with ultrasound resolution inside turbid media, and is thus interesting for biomedical applications, e.g. for assessing tissue blood oxygenation. In this paper, we present near background free measurements of UOT signal strengths using slow light filter signal detection. W
Despite low-sequence homology, the intermediate filament (IF)-like protein FilP from Streptomyces coelicolor displays structural and biochemical similarities to the metazoan nuclear IF lamin. FilP, like IF proteins, is composed of central coiled-coil domains interrupted by short linkers and flanked by head and tail domains. FilP polymerizes into repetitive filament bundles with paracrystalline pro
Recently, a lot of research focus has been on how to make solar cells more efficient. One direction is to enhance the open-circuit voltage Voc by optimizing the emission of photons in the cell, where emission is a necessary loss process due to the reciprocity between absorption and emission of light. Here, we performed a Shockley-Queisser detailed balance analysis to predict the benefit of managin
