We study connectivity in a model of a growing neuronal network in dimensions 2 and 3. Although the axon-to-dendrite proximity is an insufficient condition for establishing a functional synapse, it is still a necessary one. Therefore we study connection probabilities at short distances between the randomly grown axon trees and somas as probabilities of potential connections between the correspondin
The return of Syrian refugees has been a key topic in several forums and policy discussions over the last few years. Yet, the prospects for their return remain grim. The chapter is intended as a stimulus to further examination of an analytical debate, and offers a range of views on the argument that conditions in Syria are still not ripe for return. The chapter addresses Russia’s refugees policies
Cerebral ischemia associated with subarachnoid haemorrhage (SAH) may have severe consequences for neuronal function leading to reversible or permanent neurological deficits. The excitatory amino acid neurotransmitters, such as glutamate, have been shown to be of particular importance for ischemic neuronal damage. In seven patients who underwent early surgery for a ruptured intracranial aneurysm, m
The generation of humanized ectopic ossicles (hOss) in mice has been proposed as an advanced translational and fundamental model to study the human hematopoietic system. The approach relies on the presence of human bone marrow-derived mesenchymal stromal cells (hMSCs) supporting the engraftment of transplanted human hematopoietic stem and progenitor cells (HSPCs). However, the functional distribut
BACKGROUND: Biopsies are routinely obtained in the workup of large colorectal polyps before endoscopic resection. OBJECTIVE: This study aimed to examine how reliable biopsies are in terms of reflecting the true histopathology of large colorectal polyps, in the clinical routine. DESIGN: This is a retrospective study. SETTINGS: Data from patients undergoing polypectomy of large colorectal polyps at
PURPOSE OF REVIEW: Treatments for chronic breathlessness, including opioids and oxygen, have shown efficacy in the controlled laboratory setting, whereas effects have been inconsistent or absent in trials in daily life. This review discusses the lack of standardized exertion as a potential cause of false negative findings for breathlessness in daily life. RECENT FINDINGS: The level of breathlessne
Purpose: To analyse the activity uptakes, effective half-lives and time-integrated activities, of relevance for remnant dosimetry, for patients treated for papillary thyroid cancer (PTC) with a different amount of activity of 131I-NaI. Methods: Fifty patients were included. Of those, 18 patients had low-risk PTC and were treated with 1.11 GBq of 131I-NaI (Group 1), and 32 patients had high-risk PT
Moving along a straight path is a surprisingly difficult task. This is because, with each ensuing step, noise is generated in the motor and sensory systems, causing the animal to deviate from its intended route. When relying solely on internal sensory information to correct for this noise, the directional error generated with each stride accumulates, ultimately leading to a curved path. In contras
Ship traffic is a major source of aerosol particles, particularly near shipping lanes and harbours. In order to estimate the contribution to exposure downwind of a shipping lane, it is important to be able to measure the ship emission contribution at various distances from the source. We report on measurements of atmospheric particles 7-20 km downwind of a shipping lane in the Baltic Se
N 1s Resonant Inelastic X-ray Scattering (RIXS) was used to probe the molecular electronic structure of the ruthenium photosensitizer complex cis-bis(isothiocyanato) bis(2,2′-bipyridyl-4,4′-dicarboxylato) ruthenium(II), known as "N3." In order to interpret these data, crystalline powder samples of the bipyridine-dicarboxylic acid ligand ("bi-isonicotinic acid") and the single ring analog "isonicot
Introduction. Walking as a means of transportation is central in sustainable urban design. Little focus has, however, been placed on the influence of micro-level environmental features, such as vegetation and street lighting, on perceived safety and walking.Method. This study applied a non-explicit approach to explore the impact of greenery and outdoor lighting on neighborhood walkability. Partici
Urbanisation as a megatrend shows no signs of weakening globally, or in the Nordic countries. At the same time, the overwhelming majority of environmental impacts are generated in cities. This derives from the economic growth generated by cities, as the decoupling of economic activity from environmental impacts has not been successful to date. Moreover, from a built environment perspective, urbani
According to the EU policy documents ‘[s]aving lives of people in distress is a primary goal of EU action in relation to managing the EU external borders.’ The chosen means for achieving this objective is taking measures against human smuggling and human trafficking; these measures include the establishment of cooperation with countries of origin and transit so that migrants’ movement is prevented
There is a clear need to foresee future development and identify the possible future impacts of different elements to ensure conscious and sustainable decision making in the field of built environment. However, the level of awareness and knowhow of potential methods to assist in this task is still low among market actors as real estate education has been unable to respond to the situation. There i
