Henzinger et al. posed the so called Online Boolean Matrix-vector Multiplication (OMv) conjecture and showed that it implies tight hardness results for several basic partially dynamic or dynamic problems [STOC’15].We show that the OMv conjecture is implied by a simple off-line conjecture. If a not uniform (i.e., it might be different for different matrices) polynomial-time preprocessing of the mat
OBJECTIVES: To determine whether national antiretroviral therapy (ART) coverage is associated with changes in the living arrangements of older adults.DESIGN: Retrospective analysis using 103 nationally representative surveys from 28 African countries between 1991 and 2015.METHODS: The sample consisted of individuals aged at least 60 years. We investigated how three measures of living arrangements
Pancreatic cancer represents three percent of all incident cancer cases in developed countries, but stands the 7th most common cause of cancer related death. Worldwide, pancreatic cancer is more common among men, however in Sweden, the incidence ratio between sexes is levelling. Despite extensive research to map underlying risk factors, results are still largely inconclusive. Furthermore, there is
Wireless communication is evolving rapidly with ever more connected devicesand significantly increasing data rates. Since the invention of the smartphoneand the mass introduction of mobile apps, users demand more andmore traffic to stream music, watch high-definition video or to simply browsethe internet. This tremendous growth is more pronounced by the introductionof the Internet of Things (IoT)
PurposeThe purpose of this paper is to establish measurable factors that can be used as early indicators of which neighborhoods are most likely to undergo a process of gentrification in a reasonably near future.Design/methodology/approachUsing 1990 data on key demographic variables for 128 neighborhoods in Stockholm, Sweden a model that allows both for testing of spatial clustering and for spatial
Medical practice could be described as a drama in which doctors and patients are two actors with very different roles to play. While doctoring has traditionally been regarded as a rational and reliable activity, patienthood has been characterised by compliance with, and confidence, in the medical system. However, when doctors become ill this dichotomisation of medical practice is challenged. The a
