Recently, Brand et al. [STOC 2018] gave a randomized mathcal O(4kmϵ-2-time exponential-space algorithm to approximately compute the number of paths on k vertices in a graph G up to a multiplicative error of 1 ± ϵ based on exterior algebra. Prior to our work, this has been the state-of-the-art. In this article, we revisit the algorithm by Alon and Gutner [IWPEC 2009, TALG 2010], and obtain the foll
Understanding the dynamics of ligands bound to proteins is an important task in medicinal chemistry and drug design. However, the dominant technique for determining protein-ligand structures, X-ray crystallography, does not fully account for dynamics and cannot accurately describe the movements of ligands in protein binding sites. In this article, an alternative method, ensemble refinement, is use
Objective In 2015, new FIGO guidelines for CTG interpretation were presented (FIGO-15). In 2017, the previous Swedish guidelines (SWE-09) were replaced with guidelines adapted to FIGOs (SWE-17). The performance of these three templates had not been scientifically evaluated before its clinical implementation. The objective of this study was to compare the sensitivity and specificity to detect fetal
Linearly polarized synchrotron radiation has been used to record polarization dependent valence shell photoelectron spectra of imidazole in the photon energy range 21-100 eV. These have allowed the photoelectron angular distributions, as characterized by the anisotropy parameter β, and the electronic state intensity branching ratios to be determined. Complementing these experimental data, theoreti
Background: By examining the health needs of the general population and utilising the potential of digitalisation as a driving force, new internet-based services need to be developed in occupational therapy. However, existing guidelines for the development of complex interventions provide scant information on how to develop internet-based interventions. Aim: The aim of this paper is to share exper
Study objective: We aim to describe the variability and identify gaps in preparedness and response to the coronavirus disease 2019 pandemic in European emergency departments (EDs) caring for children. Methods: A cross-sectional point-prevalence survey was developed and disseminated through the pediatric emergency medicine research networks for Europe (Research in European Pediatric Emergency Medic
Gemensamt ägande av energi har funnits i Sverige i många år. Med Ren energi-paketet från EU etableras nu en lagstiftning som introducerar ”energigemenskaper” som en ny organisationsform på energimarknaden. Målet med denna rapport är att introducera energigemenskap, hur det beskrivs i Ren energi-paketet och i Energimarknadsinspektionens förslag till ny lag för Energigemenskaper i Sverige. I rapport
Procedural sedation and analgesia outside the operating theater have become standard care in managing pain and anxiety in children undergoing diagnostic and therapeutic procedures. The objectives of this study are to describe the current pediatric procedural sedation and analgesia practice patterns in European emergency departments, to perform a needs assessment-like analysis, and to identify barr
In May 2005, visceral leishmaniasis (VL) was recognized for the first time in Libo Kemkem, Ethiopia. In October 2005, a rapid assessment was conducted using data from 492 patients with VL treated in the district health center and a household survey of 584 residents of four villages. One subdistrict accounted for 71% of early cases, but the incidence and number of affected subdistricts increased pr
BACKGROUND: There are few reports describing the epidemiology of visceral leishmaniasis (VL) in Somalia. Over the years 2002 to 2005, a yearly average of 140 patients were reported from the Huddur centre in Bakool region, whereas in 2006, this number rose to 1002 patients. Given the limited amount of information on VL and the opportunity to compare features with the studies done in 2000 in this pa
In May 2005, visceral leishmaniasis (VL) was recognized for the first time in Libo Kemken, Ethiopia, a highland region where only few cases had been reported before. We analyzed records of VL patients treated from May 25, 2005 to December 13, 2007 by the only VL treatment center in the area, maintained by Médecins Sans Frontières-Ethiopia, Operational Center Barcelona-Athens. The median age was 18
This study reports a surveillance of multi-pesticide residues of fruits and vegetables sold in the local markets carried out in 2018–2019 in Botswana to access consumer safety. A validated method for analysis of 232 pesticide residues in fruits and vegetables was applied, based on QuEChERS-GC-MS/MS methodology. A total of 83 fruit and vegetable sold in different markets were bought from three diff
Background: To date, there is neither any pharmacological treatment with efficacy in traumatic brain injury (TBI) nor any method to halt the disease progress. This is due to an incomplete understanding of the vast complexity of the biological cascades and failure to appreciate the diversity of secondary injury mechanisms in TBI. In recent years, techniques for high-throughput characterization and
Local governments are increasingly relying on municipally owned corporations (MOCs) to provide public services. Some describe this development as a rational response to austerity challenges and emphasise the cost-efficiency of MOCs (‘the optimistic view’). Others identify complications and associate MOCs with weak supervision, lack of accountability, and corruption risks (‘the sceptical view’). Hi
