A new formulation of explicit multistep methods allows variable step-sizes by construction. This formulation can be used to construct time-adaptive strong stability preserving (SSP) multistep methods of any order for the solution of time-dependent PDEs. The new formulation is implemented in a MATLAB package, and some numerical examples are presented.
ETH Zurich Symposium on Doctoral supervision (Keynote talk, abstract))https://www.ethz.ch/en/doctorate/symposium-doctoral-supervision.htmlIn this session, we will describe how Lund University’s courses for doctoral supervisors have evolved over time and how they have been key for learning and development on the individual, collective and organisational level. The courses provide a unique arena that allows supervisors to share and investigate experiences, practices and circumstances that normally are hidden, sometimes deep within dep
The final assessment of Early Stage Researcher (ESR) activities and development follows the trajectory as previously outlined by the MEDEA Mid-term report presented at the Aarhus meetingJanuary 2017. The herein present follow-up consists of three recent activities: •An ESR group statement of pros/cons/ requested activities (Lund meeting Sep 25th 2018).•Individual ESR web survey ratings of each joi
A wide range of research school activities of the MEDEA ESR training programme were monitored through observations and repeated structured individual interviews with participating Early Stage Researchers (ESRs; i.e. doctoral students). In the early stage of the project, instructional video presentations of participating laboratories and key scientific principles turned out helpful for the early st
Swedish dissertations are public, followed by closedassessment committee meetings that only report pass-failvotes. 166 external examiners from 72 doctoral dissertationswere therefore anonymously surveyed for their views on passfail norms, scientific standard of theses and candidates and theacademic independence of the assessed candidate. They werealso asked to relate their assessment to the nation

Vector navigation, i.e., maintaining a constant heading for a given amount of time, is hypothesized to provide a viable basis for the navigational feats of a number of long-distance animal migrants. Since animals following this strategy are subject to drift by wind or by ocean current, performing long migrations relying on vector navigation is particularly challenging. We tested whether vector nav
Excessive sleep during the night and for >2 hours during the day is part of the fluctuating wakefulness criterion of dementia with Lewy bodies (DLB). The phenomenon â € sleep days' is not uncommon in nursing homes. Here, we describe a woman who, for months, slept for 3 days and nights in a row and thereafter was awake for 3 days and nights. Electroencephalogram (EEG) showed slow background activit
Sverige har både beskrivits som modernt, liberaldemoratiskt och djupt humanitärt; och som mer eller mindre förmodernt, halvauktoritärt och benäget att kränka svaga gruppers rättigheter. I den här avhandlingen undersöks detta svenska dilemma i en rättsantropologisk tradition, med studier av konfliktlösningspraktiker som ett sätt att förstå förhållandet mellan lag och kultur.Detaljerade data från tjSwedish society has been described as both modern, liberal democratic and deeply humanitarian; and as more or less premodern, semi-authoritarian and potentially abusive of groups with weak political representation. In this dissertation, this Swedish dilemma is explored in an anthropology of law tradition, with disputing practices as an inroad to an understanding of law as culture.Detailed data on
Background Functional data is data represented by functions (curves or surfaces of a low-dimensional index). Functional data often arise when measurements are collected over time or across locations. In the field of medicine, plasma lipoprotein particles can be quantified according to particle diameter by ion mobility. Goal We wanted to evaluate the utility of functional analysis for assessing the
Objectives Preventing adverse events (AEs) after orthopaedic surgery is a field with great room for improvement. A Swedish instrument for measuring AEs after hip arthroplasty based on administrative data from the national patient register is used by both the Swedish Hip Arthroplasty Register and the Swedish Association of Local Authorities and Regions. It has never been validated and its accuracy
Planetary boundaries are either being approached or already crossed, and there is no evidence for an absolute decoupling of GDP growth, resource use and greenhouse gas emissions. How economic and social systems may be reembedded into environmental limits in the absence of growth is a crucial issue within and beyond economics. This paper outlines some of the elements and analytical steps that may t
