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
Importance: Soft drinks are frequently consumed, but whether this consumption is associated with mortality risk is unknown and has been understudied in European populations to date.Objective: To examine the association between total, sugar-sweetened, and artificially sweetened soft drink consumption and subsequent total and cause-specific mortality.Design, Setting, and Participants: This populatio
Migration is an important global phenomenon fostering entrepreneurship. Migrants are individuals who are moving or have moved across an international border, or nationally across different regions or provinces, away from their habitual place of residence (UN Migration Agency, 2019). These individuals are considered migrants regardless of what their legal status is, whether the movement is voluntar
DEBATT. I ljuset av den försämrade konjunkturen höjs allt fler röster för en generösare finanspolitik. Men Sveriges ekonomiska utmaningar går djupare och budskapet från bland annat Japan och USA är tydligt: stora budgetunderskott höjer inte tillväxten på sikt, skriver Fredrik NG Andersson och Lars Jonung vid Lunds universitet.
Mechanisms of protein-guided mineralization in enamel, leading to organized fibrillar apatite nanocrystals, remain elusive. In vitro studies reveal recombinant human amelogenin (rH174), a matrix protein templating this process, self-assembles into a variety of structures. This study endeavors to clarify the self-assembly of rH174 in physiologically relevant conditions. Self-assembly in simulated e
Purpose We investigated if early intensive care unit (ICU) scoring with the Simplified Acute Physiology Score (SAPS 3) could be improved using artificial neural networks (ANNs). Methods All first-time adult intensive care admissions in Sweden during 2009-2017 were included. A test set was set aside for validation. We trained ANNs with two hidden layers with random hyper-parameters and retained the
