Bone microarchitecture in ankylosing spondylitis and the association with bone mineral density, fractures, and syndesmophytes

INTRODUCTION: Osteoporosis of the axial skeleton is a known complication of ankylosing spondylitis (AS), but bone loss affecting the peripheral skeleton is less studied. This study on volumetric bone mineral density (vBMD) and bone microarchitecture in AS was conducted to compare peripheral vBMD in AS patients with that in healthy controls, to study vBMD in axial compared with peripheral bone, and

Gaia : Focus, straylight and basic angle

The Gaia all-sky astrometric survey is challenged by several issues affecting the spacecraft stability. Amongst them, we find the focus evolution, straylight and basic angle variations Contrary to pre-launch expectations, the image quality is continuously evolving, during commissioning and the nominal mission. Payload decontaminations and wavefront sensor assisted refocuses have been carried out t

The Stockholm Festival, 1966

The article is an introduction to the festival 'Visioner av Nuet' Stockholm, 1966. The article focuses on the historical event, and contextualizes it to both the discussions on art and technology at the time, and to the planned collaborations with the prominent artists from the American group E.A.T. such as Billy Klüver, John Cage, Robert Rauchenberg and Öyvind Fahlström, - collaborations that nev

Near-Surface Geophysical Characterization of Areas Prone to Natural Hazards : A Review of the Current and Perspective on the Future

Natural hazards such as landslides, floods, rockfalls, earthquakes, volcanic eruptions, sinkholes, and snow avalanches represent potential risks to our infrastructures, properties, and lives. That potential will continue to escalate with current and continued human encroachment into risk areas. With the help of geophysical techniques many of those risks can be better understood and quantified, the

Feeding by Scolytus bark beetles to test for differently susceptible elm varieties

Dutch elm disease (DED), caused by the fungi Ophiostoma ulmi and O. novo-ulmi, has reduced elm populations severely in Europe and North America. Breeding programmes are in action to find less susceptible elm varieties suitable for re-establishing elm stands. Bark beetles, mainly Scolytus spp., are the only known natural vectors of DED. During twig feeding, beetles transfer Ophiostoma spores to hea

Evaluation and sociolinguistic analysis of text features for gender and age identification

The paper presents an interdisciplinary study in the field of automatic gender and age identification, under the scope of sociolinguistic knowledge on gendered and age linguistic choices that social media users make. The authors investigated and gathered standard and novel text features used in text mining approaches on the author’s demographic information and profiling and they examined their eff

Jesuiterna och den nordiska konversionsrörelsen

I de nordiska länderna betraktades jesuiterna av tradition som själva sinnebilden för den ”katolska faran” och för allt det onda som av hävd förknippades med katolicismen. Men trots det var det just jesuiterna som drog till sig flest konvertiter, och ”jesuitförsamlingarna” fungerade som dragplåster för intresserade protestanter. Vad var förklaringen till detta? Hur såg man på konversioner i den ka

Revisiting orientations in language planning : Problem, right, and resource as an analytical heuristic

In 1984, Richard Ruiz set forth three orientations to language planning: language as problem, language as right, and language as resource. Since that time, the orientations have only become more powerful, rising to the level of paradigm in the field of language policy and planning (LPP). In this paper, we revisit Ruiz’s orientations. By drawing upon Ruiz’s own work as well as the work of other sch

Terrorism, Belief Formation, and Residential Integration : Population Dynamics in the Aftermath of the 2004 Madrid Terror Bombings

In this article, we study the effects of the 2004 terrorist bombings in Madrid on ethnic segregation in Spain. Using large-scale Spanish register data consisting of information on 5.4 million international migration events on a monthly basis and 13.9 million intermunicipal migration events, of which 3.8 million events concern the foreign-born population’s internal migration within Spain, the analy

M1 Macrophages Are Predominantly Recruited to the Major Pelvic Ganglion of the Rat Following Cavernous Nerve Injury

Introduction Neurogenic erectile dysfunction is a common sequela of radical prostatectomy. The etiology involves injury to the autonomic cavernous nerves, which arise from the major pelvic ganglion (MPG), and subsequent neuroinflammation, which leads to recruitment of macrophages to the injury site. Currently, two macrophage phenotypes are known: neurotoxic M1 macrophages and neuroprotective M2 ma

Particle Filter for Combined Wheel-Slip and Vehicle-Motion Estimation

The vehicle-estimation problem is approached by fusing measurements from wheel encoders, an inertial measurement unit, and (optionally) a global positioning system in a Rao-Blackwellized particle filter. In total 14 states are estimated, including key variables in active safety systems, such as longitudinal velocity, roll angle, and wheel slip for all four wheels. The method only relies on kinemat

Frequent low-level mutations of Protein Kinase D2 in angiolipoma

Tumours displaying differentiation towards normal fat constitute the most common subgroup of soft tissue neoplasms. A series of such tumours was investigated by whole-exome sequencing followed by targeted ultra-deep sequencing. Eighty percent of angiolipomas, but not any other tumour type, displayed mutations in the protein kinase D2 (PRKD2) gene, typically in the part encoding the catalytic domai

Thermal stability and structural changes in bacterial toxins responsible for food poisoning

The staphylococcal enterotoxins (SEs) are secreted by the bacteria Staphylococcus aureus and are the most common causative agent in staphylococcal food poisoning. The staphylococcal enterotoxin A (SEA) has been associated with large staphylococcal food poisoning outbreaks, but newer identified SEs, like staphylococcal enterotoxin H (SEH) has recently been shown to be present at similar levels as S
