This thesis delves into the complex architecture of dynamic sensory information processing in the neocortex. Specifically, it asks how primary sensory cortical regions are influenced by local and widespread cortical state changes. Central to this question is the exploration of two historically opposing information processing frameworks emphasizing a local and global information processing principl

We introduce the concept photophysical image analysis (PIA) and an associated pipeline for unsupervised probabilistic image thresholding for images recorded by electron-multiplying charge-coupled device (EMCCD) cameras. We base our approach on a closed-form analytic expression for the characteristic function (Fourier-transform of the probability mass function) for the image counts recorded in an E

Light is a key factor in poultry production; however, there is still a lack of knowledge as to describing the light quality, how to measure the light environment as perceived by birds, and how artificial light compares with the light in the natural forest habitats of their wild ancestors. The aim of this study was to describe the light environment in broiler breeder houses with three different lig

Aims. We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from the sixth internal data release of Gaia-ESO, IDR6, and from the Gaia Early Data Release 3, EDR3s. Methods. We selected a sample of main-sequence, sub-giant, and giant stars in which the Li abundance is measured by th

Framväxten av digitala plattformar håller för närvarande på att förändra hur kulturarbete förmedlas och utförs. Trots detta finns det en brist på forskning, inte minst i en svensk kontext, som studerar kulturarbete som ett typexempel på det som kommit att kallas gigarbete. Den här avhandlingen analyserar frilansande kulturarbetares erfarenheter av att navigera den digitala plattformsekonomin för aCultural industries are currently being transformed by processes of platformization and precarization. Despite being among the sectors where platformization has already had the most pronounced effects, there remains a lack of research on cultural work as a prototypical example of so-called gig work. This dissertation analyzes the working experiences of what I call digital freelancers — solo self-e

Because of varied topography and landscape heterogeneity，Tianshan Mountain has extremely complex hydrological processes. Considering that the climate change poses a great threat to the water security，it’s necessary to simulate the change of water elements quantitatively and systematically along with elevation. In this study，we applied the modified FLEXG-Δh model to four classic river basins in Tia

Background: Preterm and low birth weight infants are at an early stage of development, and do not receive adequate maternal circadian signals. They are often cared for over prolonged periods of hospitalisation in neonatal intensive care units (NICU), where environmental circadian stimuli are lacking. Exposure to artificial light–dark cycles may stimulate the development of the circadian system and

We study whether one reason behind female underrepresentation in leadership is that female leaders are less effective at coordinating followers’ actions. Two experiments using coordination games investigate whether female leaders are less successful than males in persuading followers to coordinate on efficient equilibria. In these settings, successful coordination hinges on higher-order beliefs ab

Zinc phthalocyanine (ZnPc) adsorbed on the InSb(0 0 1)-c(8 x 2) surface has been studied by scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). Coverages from sub-monolayer to monolayer (ML) have been investigated. The molecules form ordered structures on the reconstructed rows of the surface with the molecular plane parallel to the surface. A change in the electronic s

This paper provides a new decision rule for emergency replenishments in an inventory system. The decision rule is a generalization of a previous decision rule suggested and evaluated in Axsater (2003, 2007). An improvement step is added to this rule and this often means considerably better performance. The decisions are based on complete information about the system state. An advantage with our de

Popular AbstractDen nya världsordningen som Castells kallar för nätverksamhälle skapar en konflikt mellan globalisering och identitet. I detta avseende blir frågan om identitet och etniska gränser, i Barths mening, ett centralt tema för att förstå samhällsförändringar. Globaliseringsprocessen håller på att skapa en försvagning av det civila samhället och med detta försvagas också förhållandena melThe new world order, that Castells denominates network society, generates a conflict between the globalisation and identity. In this sense the questions of identity and ethnic boundaries,in Barth’s meaning, emerge as a central subject to understanding societal changes. Globalisation is causing a weakening of the civil society, the relationship between the nation state and the people is also debili

In this chapter, I argue that moving as a way to counter the negative aspects of ageing (actual as well as symbolic), is both dependent on mobility and contradictory to it. The overall purpose is to investigate the relation between moving and mobility in the accounts told by people who have chosen to migrate as seniors in order to enable a certain lifestyle. In what way does the discursive ideal o

Popular Abstract in Swedish Satser i objektsposition i modern standardarabiska. MODERN STANDARDARABISKA Arabiska talas idag av ca 200 miljoner människor från Marocko och Mauretanien i väster till Irak och Oman i öster. De talade varianterna av språket skiljer sig åt ganska mycket, men man har ett gemensamt skriftspråk. Den moderna varianten av skriftspråket kallas ofta modern standardarabiska ocThis dissertation comprises a corpus-based study of the form and function of sentential object complements in Modern Standard Arabic (MSA). The study is motivated by the scarcity of investigations into MSA syntax as opposed to the syntax of Classical Arabic. Complements to three classes of complement-taking predicates (CTPs) ­ manipulation, cognition and utterance ­ are considered. The major part

Popular Abstract in Swedish I Sverige bryter drygt 30 000 föräldrapar årligen upp från sin relation. Tillsammans har dessa föräldrar cirka 55 000 barn. I samband med föräldrarnas separation skall frågor om de gemensamma barnens vårdnad, boende och umgänge lösas. De flesta föräldrar klarar detta på egen hand eller med stöd av samarbetssamtal eller familjerådgivning, men ungefär 10% av de separerandThe purpose of this socio-legal dissertation is to examine the role of the district court in the handling of custody disputes, from the standpoint of the child's best interest. More specifically, the focus is partly on the relationship between the family and society during district court proceedings, and partly on the relationship between civil law and public law procedure that is to say between t

This article discusses the role of archaeology in our society as well as the epistemological outlook within archaeology. In order to illustrate the relevance of archaeology in our own age three topics are formulated - landscape archaeology, the long-term perspectives of archaeology and the norms and values of our particular system. It is underlines that archaeologists are interpreters of fragments

OBJECTIVE :Patients with symptoms and signs compatible with psoriatic arthritis (PsA), with or without psoriasis, have been documented in the Swedish Early Psoriatic Arthritis (SwePsA) register. Our aim was to find markers for disease progression and to evaluate treatments for PsA using these data. METHODS: Patients referred to rheumatology outpatient clinics within 2 years of onset were assessed

Land-use and land-cover change (LULCC) represents one of the key drivers of global environmental change. However, the processes and drivers of anthropogenic land-use activity are still overly simplistically implemented in terrestrial biosphere models (TBMs). The published results of these models are used in major assessments of processes and impacts of global environmental change, such as the repo

We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200

In order to understand why individuals accept and reproduce excessive time regimes, this paper addresses five key drivers: (1) intrinsic motivation, (2) extrinsic motivation, (3) organizational norms, (4) the principle of reciprocity, and (5) identity, including having the ‘true grit’ and belonging to the ‘elite’. It also points to how various elements in excessive work regimes – tendencies toward

Background/Objectives A cascade of gene activations under the control of Notch signalling is required during T-cell specification, when T-cell precursors gradually lose the potential to undertake other fates and become fully committed to the T-cell lineage.We elucidate how the gene/protein dynamics for a core transcriptional module governs this important process by computational means. Methods We
