Traffic on railways is increasing and this makes train traffic to be highly interconnected . This paper investigates how passing of train affects dwell time delays in Sweden. Three scenarios are considered by combining the scheduled and actual operations: passes that happened as scheduled, unscheduled passes that happened in operations, and scheduled passes that were cancelled. A logistic regressi

This study investigates how the volume and flow of passengers affect dwell times, usingdata from commuter trains in Stockholm. We show that dwell times often take longer thanscheduled and that most station stops involve rather limited numbers of passengers.Improving the performance at these stops with small volumes can thus have a sizeableimpact on the overall on-time performance. We find a quadraThis study investigates how the volume and flow of passengers affect dwell times, using data from commuter trains in Stockholm.

Only well-maintained railway systems can function without severe interruptions. However,maintenance activities can themselves cause train delays if they conflict with trainmovements. Trackwork refers to maintenance performed on a railway track. This studyaims to investigate the effect of trackwork on train delays in Sweden. It presents a logisticregression analysis based on more than 225,000 plannOnly well-maintained railway systems can function without severe interruptions.

The fourth enzymatic reaction in the de novo pyrimidine biosynthesis, the oxidation of dihydroorotate to orotate, is catalyzed by dihydroorotate dehydrogenase (DHODH). Enzymes belonging to the DHODH Class II are membrane-bound proteins that use ubiquinones as their electron acceptors. We have designed this study to understand the interaction of an N-terminally truncated human DHODH (HsΔ29DHODH) an

Train delays are often monitored using lag indicators of achieved punctuality levels, but indicators can also be used proactively aslead indicators to help reach a certain level of punctuality. In this paper, two lead indicators – the share of delayed dwell times andthe share of delayed run times – are formulated and tested on Swedish commuter train data for the years 2001-2020. Results showthat iTrain delays are often monitored using lag indicators of achieved punctuality levels, but indicators can also be used proactively as lead indicators to help reach a certain level of punctuality.

We consider the fundamental problem of assigning distinct labels to agents in the probabilistic model of population protocols. Our protocols operate under the assumption that the size n of the population is embedded in the transition function. Their efficiency is expressed in terms of the number of states utilized by agents, the size of the range from which the labels are drawn, and the expected n

Background:Traditional primary care is characterized by patient consultations via phone and physical visits. However, the current development in Swedish primary care is to blend digital solutions with traditional solutions. This paper addresses this development by examining the normalization of embedding and integrating a digital health care platform into everyday care routines in a primary care cBackground:Traditional primary care is characterized by patient consultations via phone and physical visits.

Purpose: To study retinal appearance and morphology in Labrador retrievers (LRs) heterozygous and homozygous for an ABCA4 loss-of-function mutation.Methods: Ophthalmic examination, including ophthalmoscopy and simple testing of vision, was performed in five ABCA4wt/wt, four ABCA4wt/InsC, and six ABCA4InsC/InsC LRs. Retinas were also examined with confocal scanning laser ophthalmoscopy (cSLO) and o

Human aquaporin 10 (hAQP10) is an aquaglyceroporin that assists in maintaining glycerol flux in adipocytes during lipolysis at low pH. Hence, a molecular understanding of the pH-sensitive glycerol conductance may open up for drug development in obesity and metabolically related disorders. Control of hAQP10-mediated glycerol flux has been linked to the cytoplasmic end of the channel, where a unique

PURPOSE: To compare two aflibercept treatment regimens and the electrophysiological outcome concerning cone and rod function in age-related macular degeneration (nAMD) over 18 months.METHODS: 41 patients with treatment-naïve nAMD were randomized 1:1 to either arm 1 or 2. Arm 1 received three consecutive monthly aflibercept injections, followed by bimonthly treatment until week 52. Thereafter, a tr
