Anhedoni, minskad motivation att uppleva lust, är associerad med förändringar i belöningssystemet. Belägen i ventrala striatum utgör den bilaterala nucleus accumbens (NAcc) den centrala noden i detta nätverk, där dopamin agerar som huvudsaklig excitatorisk neurotransmitter. Studier med funktionell magnetresonanstomografi (fMRI) har visat att aktiviteten i ventrala striatum minskar under belöningsbAnhedonia, reduced motivation to experience pleasure, is associated with alterations in the circuitry of the reward system. Located in the ventral striatum, the bilateral nucleus accumbens (NAcc) is the central hub of this network where dopamine acts as the main excitatory neurotransmitter. Studies using functional magnetic resonance imaging (fMRI) found that activity in the ventral striatum is de

Nineteen pre-school children with language impairment participated in a computerized naming task. The naming procedure involved two conditions, one unprimed where the child had to name a colour picture appearing on the screen as fast as possible and one primed where the picture was preceded by an uncompleted sentence. Response times were significantly shorter in the primed condition compared to th

Neuropsychological test-based norms are vital for accurate assessment of older adults’ level of cognition. Hence, it is important that these scores are not conflated with birth cohort effects. With data drawn from the Swedish Good Ageing in Skåne (GÅS) population study, this study examined birth cohort effects on test scores measuring several cognitive domains. A time-lag design with three distinc

OBJECTIVE: The overall objective was to unfold the phenomenon of interrater agreement: to identify potential sources of variation in agreement data and to explore how they can be statistically accounted for. The ultimate aim was to propose recommendations for in-depth examination of agreement to improve the reliability of assessment instruments. STUDY DESIGN AND SETTING: Using a sample where 1

This study aims to examine customer acquisition strategies of multisided platforms and consumer perception towards them. It further aims to contribute to current literature by addressing present uncertainty regarding the relationship of customer acquisition and consumer perception. From a practical perspective it should help other multisided platforms to identify customer acquisition methods that

Försörjningskedjan har stor potential till optimering. Många olika delar av kedjan kan optimeras och alla tänkbara förbättringar har inte testats än. Denna studien har sitt fokus på ruttoptimering, med det specifika målet att förstå hur maskininlärning kan användas inom ruttplanering, samt hur nyckelfaktorer som påverkar restiden för en rutt kan tas i åtanke för problemet. Tid lades på att studerThe supply chain has potential for growth. Many different parts can be optimized, and every possible improvement has not yet been tested. This study focuses on route optimization with the specific goal of figuring out how machine learning can be applied to route planning and how key factors that impact travel time for a route can be taken into account for this problem. Time was dedicated to learn

This article discusses the role of the protein corona in delivery systems with tagged nanoparticles and how knowledge of the protein corona can help in optimizing delivery. The basic question is whether and how the binding of proteins and other biomolecules at the nanoparticle surface interfere with the interaction between a tag and its receptor. This is an interesting problem in many respects, bu

Muhammad Hejazi, deputy head of the Iranian Quds Force, is reported to have died of heart disease. However, a mysterious tweet hints that he might have been killed.
