WYK: Mobile Device Authentication Using the User’s Address Book
(Chapter, 2022)Authenticating a user the correct way is paramount to IT systems, where the risk is growing more and more in number and complexity. This is specially important in mobile phones, where a number of applications require ... -
X-chromosome and kidney function: evidence from a multi-trait genetic analysis of 908,697 individuals reveals sex-specific and sex-differential findings in genes regulated by androgen response elements
(Peer reviewed; Journal article, 2024)X-chromosomal genetic variants are understudied but can yield valuable insights into sexually dimorphic human traits and diseases. We performed a sex-stratified cross-ancestry X-chromosome-wide association meta-analysis ... -
X-ray absorption, X-ray diffraction and electron microscopy study of spent cobalt based catalyst in semi-commercial scale Fischer-Tropsch synthesis
(Peer reviewed; Journal article, 2014)Calcined, reduced and spent Co-Re/γ-Al2O3 catalysts for Fischer–Tropsch synthesis (FTS) were characterized and compared. Co-K-edge and Re-LIII-edge X-ray absorption near edge structure (XANES), X-ray powder diffraction ... -
X-ray computed tomography investigation of dilation of mineral-filled PVC under monotonic loading
(Peer reviewed; Journal article, 2019)The deformation-induced dilation of mineral-filled polyvinyl chloride (PVC) is investigated by means of polychromatic X-ray absorption tomography (XCT). Axisymmetric notched tensile specimens are strained to prescribed ... -
An X-ray micro-tomographic study of the pore space, permeability and percolation threshold of young sea ice
(Journal article; Peer reviewed, 2021) -
X-ray Microprobe Investigation of Iron During a Simulated Silicon Feedstock Extraction Process
(Peer reviewed; Journal article, 2016)Elemental silicon is extracted through carbothermic reduction from silicon-bearing raw feedstock materials such as quartz and quartzites. We investigate the micron-scale distribution and valence state of iron, a deleterious ... -
X-ray nanoscopy of a bulk heterojunction
(Journal article; Peer reviewed, 2016)Optimizing the morphology of bulk heterojunctions is known to significantly improve the photovoltaic performance of organic solar cells, but available quantitative imaging techniques are few and have severe limitations. ... -
X-ray repair cross complementing protein 1 in base excision repair
(Journal article; Peer reviewed, 2012)X-ray Repair Cross Complementing protein 1 (XRCC1) acts as a scaffolding protein in the converging base excision repair (BER) and single strand break repair (SSBR) pathways. XRCC1 also interacts with itself and rapidly ... -
X-ray Studies of Carbon Dioxide Intercalation in Na-Fluorohectorite Clay at Near-Ambient Conditions
(Journal article, 2012)We show experimentally that gaseous CO2 intercalates into the interlayer space of the synthetic smectite clay Na-fluorohectorite at conditions not too far from ambient. The mean interlayer repetition distance of the clay ... -
X65 steel pipes subjected to combined stretching and bending
(Chapter, 2015)Subsea pipelines are occasionally struck and hooked by objects such as anchors or trawl gear. The initial denting followed by a potential hooking and displacement of the pipeline, with a simultaneous increase in tensile ... -
An XAI approach for COVID-19 detection using transfer learning with X-ray images
(Peer reviewed; Journal article, 2023)The coronavirus disease (COVID-19) has continued to cause severe challenges during this unprecedented time, affecting every part of daily life in terms of health, economics, and social development. There is an increasing ... -
Xandarovula patula (Gastropoda: Ovulidae) new to Scandinavia
(Journal article; Peer reviewed, 2011)In August 2009 six specimens of the ovulid gastropod Xandarovula patula (Pennant, 1777) (formerly known as Simnia patula Pennant, 1777), were found in dredge samples from a locality west of Smögen in western Sweden (58°22′N ... -
XAS investigation of silica aerogel supported cobalt rhenium catalysts for ammonia decomposition
(Peer reviewed; Journal article, 2020)The implementation of ammonia as a hydrogen vector relies on the development of active catalysts to release hydrogen on-demand at low temperatures. As an alternative to ruthenium-based catalysts, herein we report the ... -
XPS and GDOES characterization of porous coating enriched with copper and calcium obtained on tantalum via plasma electrolytic oxidation
(Peer reviewed; Journal article, 2016)XPS and GDOES characterizations of porous coatings on tantalum after Plasma Electrolytic Oxidation (PEO) at 450 V for 3 minutes in electrolyte containing concentrated (85%) phosphoric acid with calcium nitrate and copper ... -
XPS Examination of the Oxide-Metal Interface of an Aluminum-Magnesium Alloy Containing Beryllium
(Chapter, 2018)The addition of beryllium to high magnesium aluminum alloys has long been known to cause a significant decrease in the rate of alloy oxidation. A clear understanding of the fundamental mechanism behind this effect is still ... -
