Problematic gaming and internet use but not gambling may be overrepresented in sexual minorities - A pilot population web survey study
Background: Substance-related addictive disorders are known to be overrepresented in non-heterosexual individuals, but it is largely unknown whether this is also the case for behavioral addictions such as problem gaming and gambling. This study aimed, in a pilot web survey design, to assess whether problematic gambling, gaming and internet use may be more common in individuals with a non-heterosex
Clinical phenotype, atrophy, and small vessel disease in APOEε2 carriers with Alzheimer disease
OBJECTIVE: To examine the clinical phenotype, gray matter atrophy patterns, and small vessel disease in patients who developed prodromal or probable Alzheimer disease dementia, despite carrying the protective APOEε2 allele. METHODS: We included 36 β-amyloid-positive (by CSF or PET) APOEε2 carriers (all ε2/ε3) with mild cognitive impairment or dementia due to Alzheimer disease who were matched for
Calcium-activated chloride channel regulator 1 as a prognostic biomarker in pancreatic ductal adenocarcinoma
BACKGROUND: In a previous study utilizing mass spectrometry-based proteomics, we identified calcium-activated chloride channel regulator 1 (CLCA1) as a potential tumor suppressor in pancreatic cancer and the expression was inversely correlated with patient survival. The aim of the study was to further validate the prognostic significance of CLCA1 in pancreatic cancer. METHODS: CLCA1 expression was
Qualitative cross-country comparison of whether, when and how people diagnosed with lung cancer talk about cigarette smoking in narrative interviews
OBJECTIVES: To compare and examine whether, when and how patients with lung cancer in three countries, with different survival rates, talk about cigarette smoking and its relationship with help-seeking. DESIGN: A qualitative cross-country comparison with analysis of narrative interviews. SETTING: Participants in Sweden, Denmark and England were interviewed during 2015-2016. Interviews, using a nar
Human adipose glycerol flux is regulated by a pH gate in AQP10
Obesity is a major threat to global health and metabolically associated with glycerol homeostasis. Here we demonstrate that in human adipocytes, the decreased pH observed during lipolysis (fat burning) correlates with increased glycerol release and stimulation of aquaglyceroporin AQP10. The crystal structure of human AQP10 determined at 2.3 Å resolution unveils the molecular basis for pH modulatio
Key climate oscillation factors controlling precipitation variability during the dry season in eastern northeast Brazil : Study case of Mundaú and Paraíba do Meio river basins
In Brazil, the northeastern region (NEB) is considered one of the most vulnerable areas of the country in terms of precipitation variability due to frequent drought episodes during the rainy season. Differently from the Northern NEB (NNEB), where dry season is consistently dry, the Eastern NEB (ENEB) exhibits a high interannual variability of precipitation during the dry season, including years ex
Navigating cognition : Spatial codes for human thinking
The hippocampal formation has long been suggested to underlie both memory formation and spatial navigation. We discuss how neural mechanisms identified in spatial navigation research operate across information domains to support a wide spectrum of cognitive functions. In our framework, place and grid cell population codes provide a representational format to map variable dimensions of cognitive sp

Performance of a feature-based algorithm for 3D-3D registration of CT angiography to cone-beam CT for endovascular repair of complex abdominal aortic aneurysms
Background: A crucial step in image fusion for intraoperative guidance during endovascular procedures is the registration of preoperative computed tomography angiography (CTA) with intraoperative Cone Beam CT (CBCT). Automatic tools for image registration facilitate the 3D image guidance workflow. However their performance is not always satisfactory. The aim of this study is to assess the accuracy

Negotiating ‘Voice’ in the Space Between: Using digital platforms for transformative and transnational knowledge production
In this paper, we present the findings of a Universitas 21 (U21) Graduate Research Project collaboration between Pontificia Universidad Católica de Chile, the University of Nottingham, England, and Lund University, Sweden. This project brought together six doctoral candidates at various stages in their postgraduate careers. The students had conducted qualitative and quantitative inquiry into diver
TruSDN: Bootstrapping Trust in Cloud Network Infrastructure
Software-Defined Networking (SDN) is a novel architectural model for cloud network infrastructure, improving resource utilization, scalability and administration. SDN deployments increasingly rely on virtual switches executing on commodity operating systems with large code bases, which are prime targets for adversaries attacking the network infrastructure. We describe and implement TruSDN , a fram

Threats to 5G group-based authentication
The fifth generation wireless system (5G) is expected to handle an unpredictable number of heterogeneous connected devices and to guarantee at least the same level of security provided by the contemporary wireless standards, including the Authentication and Key Agreement (AKA) protocol. The current AKA protocol has not been designed to efficiently support a very large number of devices. Hence, a n

A secure group-based AKA protocol for machine-type communications
The fifth generation wireless system (5G) is expected to handle with an unpredictable number of heterogeneous connected devices while guaranteeing a high level of security. This paper advances a groupbased Authentication and Key Agreement (AKA) protocol that contributes to reduce latency and bandwidth consumption, and scales up to a very large number of devices. A central feature of the proposed p
A high assurance virtualization platform for ARMv8
This paper presents the first results from the ongoing research project HASPOC, developing a high assurance virtualization platform for the ARMv8 CPU architecture. Formal verification at machine code level guarantees information isolation between different guest systems (e.g. OSs) running on the platform. To use the platform in networking scenarios, we allow guest systems to securely communicate w
ARCLUS: A New jet clustering algorithm inspired by the color dipole model
A new jet clustering algorithm-Arclus-is presented. The main difference between this and conventional algorithms is that while the latter in each step join two clusters into one,Arclus joins three clusters into two. The performance ofArclus in terms of the size of hadronization corrections is studied for some jet-reconstruction tasks ine+e− andep collisions, and is found to be as good as or, for s
