It has recently been found that anti-Stokes photoluminescence can be observed in degenerately n-doped indium phosphide nanowires, when exciting directly into the electron gas. This anti-Stokes mechanism has not been observed before and allows the study of carrier relaxation and recombination using standard photoluminescence techniques. It is important to know if this anti-Stokes photoluminescence

The present study investigated the relationship between linguistic tone processing and cortical thickness of bilateral planum temporale (PT) and pars opercularis of the inferior frontal gyrus (IFGpo). Swedish tones on word stems function as cues to upcoming endings. Correlating structural brain imaging data with participants’ response time patterns for suffixes, we found that thicker cortex in the

Computational modelling of neurons on different scales provides not only methods to explore mechanisms observed in vivo but also for testing hypotheses that would be impossible physiologically. In this paper we present initial computational analysis of insect lobula small target motion detector (STMD) neurons. We simulate a multicompartment model in combination with a bioinspired model for front-e

When obtaining samples for population genetic studies, it is essential that the sampling is random. For Drosophila, one of the crucial steps in sampling experimental flies is the collection of eggs. Here an egg collection method is presented, which randomizes the eggs in a water column and diminishes environmental variance. This method was compared with a traditional egg collection method where eg

The Edictum Diocletiani et collegarum: The so-called Edict of Maximum Prices was issued in AD 301 as part of a comprehensive administrative and financial reform released in the reign of the Roman emperor Diocletian. Diocletian came to power in AD 284 after a period in Roman history traditionally understood as a time of ‘crisis’, produced by a series of inter-related factors: a frequent turnover of

För varje typ av djur finns en optimal storlek, men större är ofta bättre. För 300 miljoner år sedan var jättelika drakeflugor de största insekterna någonsin. Högre atmosfäriska syrekoncentrationer tros ha tillåtit dem att både flyga och utvecklas till jättar. Men idag är de största sländorna inte större än en mänsklig hand och tar decennier att utvecklas till vuxna. Men varför blir kråkmått ellerBody size and body temperature are the two most important traits in biology. In this thesis I show how these twovariables have shaped the evolution of insects over the last 300 million years. These variables are so important infact that three rules have been developed to summarize their effects: (1) bigger is better, (2) hotter makes yousmaller, and (3) hotter is better.Using primarily dragonflies

This letter presents the first measurement of jet mass in Pb–Pb and p–Pb collisions at sNN=2.76 TeV and sNN=5.02 TeV, respectively. Both the jet energy and the jet mass are expected to be sensitive to jet quenching in the hot Quantum Chromodynamics (QCD) matter created in nuclear collisions at collider energies. Jets are reconstructed from charged particles using the anti-kT jet algorithm and reso

Purpose: Dysfunctional proteostasis, with decreased protein degradation and an accumulation of ubiquitin into aggregated protein inclusions, is a feature of neurodegenerative diseases. Identifying new potential biomarkers in cerebrospinal fluid (CSF) reflecting this process could contribute important information on pathophysiology. Experimental design: A developed method combining SPE and PRM-MS i

This paper presents a measurement of the triple-differential cross section for the Drell-Yan process Z/γ* → ℓ+ℓ− where ℓ is an electron or a muon. The measurement is performed for invariant masses of the lepton pairs, mℓℓ, between 46 and 200 GeV using a sample of 20.2 fb−1 of pp collisions data at a centre-of-mass energy of s=8 TeV collected by the ATLAS detector at the LHC in 2012. The data are p

The gut microbiomes of birds and other animals are increasingly being studied in ecological and evolutionary contexts. Numerous studies on birds and reptiles have made inferences about gut microbiota using cloacal sampling; however, it is not known whether the bacterial community of the cloaca provides an accurate representation of the gut microbiome. We examined the accuracy with which cloacal sw

In this paper, a study on the performance of surface irrigation of date palms in a Tunisian arid area (Douz oasis) is presented. The study is conducted in 16 plots with various sizes and soil textures over a 4-year period (2012–2015). In the first step, an assessment of total water requirements of the date palms is carried out. Then, the surface irrigation performance is analyzed using three indic

‘Sustainability’, often presented through an ecological–economic–social triad, is today one of spatial planning’s absolute key concepts (and key priorities). But it is also a highly contested concept, whose meaning is often considered evasive or vague. In this paper, we try to counterweigh such evasiveness by putting emphasis on the material landscape produced within a project that is frequently d
