Data rate requirements for cellular communications are expected to increase 1000–fold by 2020, compared to 2010. This is mainly because of the rapid increase in the number of wireless devices and data hungry applications per–device. This creates a formidable bandwidth crisis. Milimeter–wave (mmWave) systems with massive multiple–input multiple–output (MIMO) operation are two complementary concepts

The association between contextual factors and health inequalities is well documented, also in Brazil. However, questions about how contextual factors actually affect health and well-being persist. The aim of this qualitative study was to explore how contextual factors-i.e., social stratification and neighborhood opportunity structures-are manifested in the lives of the residents of a vulnerable d

This chapter begins by providing a general contextualisation of hate speech and the controversies around it. It then asks two questions: Is Holocaust denial a form of hate speech? If the answer is positive, should Holocaust denial be banned?The second section explains what is hate speech. The third section is concerned with the relationship between hate speech and hate crime. The fourth section di

Over the last thirty years, suggestions for how to develop defence capability have developed rapidly. However, supporting theory and structured concept development lag behind. Despite this imbalance, countries need to continuously spend resources on defence development. This study identifies central challenges in relation to the scientific perspectives and approaches needed to support the developm

This chapter discusses the inaugural dissertation of the first ex officio professor of natural law in Denmark, Andreas Hojer: the 1735 Dissertatio iuris publici universalis de eo quod iure belli licet in minores. In doing so, it seeks to shed light on a little-known figure in the early Danish enlightenment, albeit one who was very influential in his day. It explains why Hojer chose what, on the fa

Background: Treatment of common bile duct (CBD) stones after Roux-en-Y gastric bypass (RYGB) poses a particular challenge given the altered anatomy and inability to perform a standard endoscopic retrograde cholangiogram (ERC). The optimal treatment strategy for intraoperatively encountered CBD stones in post-RYGB patients has not been established. Objectives: To compare outcomes following laparosc

Mammalian metabolism comprises a series of interlinking pathways that include two major cycles: the folate and methionine cycles. The folate-mediated metabolic cycle uses several oxidation states of tetrahydrofolate to carry activated one-carbon units to be readily used and interconverted within the cell, which are required for nucleotide synthesis, methylation and metabolism, particularly for pro

Podcast "Öppet fall" från Lunds universitet, Juridiska fakulteten: I november 2020 slår en ovanligt stor meteorit ner i skogarna norr om Enköping. Under de följande veckorna söker två geologer systematiskt igenom området tills de hittar meteoriten. När markägaren får höra om fyndet uppkommer en tvist som går till domstol. Markägaren hävdar att meteoriten tillhör honom, medan geologerna hävdar att

Flowing water impacts bridges over rivers primarily in two ways: (1) hydrodynamic forces that directly impact the structure and (2) scouring at piers and abutments, including contraction scour. The design prin-ciples for bridges in Sweden, including both impacting forces and local scour, are relatively simplistic. The purpose of this paper is to examine the impact of extreme river flows on bridges

BACKGROUND: To analyze the potential effect of social inequality on pancreatic cancer risk in Western Europe, by reassessing the association within the European Prospective Investigation into Cancer and Nutrition (EPIC) Study, including a larger number of cases and an extended follow-up.METHODS: Data on highest education attained were gathered for 459,170 participants (70% women) from 10 European
