We introduce the point process [Formula presented] where Zn is the normalization constant. This point process is attractive: it involves n dependent, uniformly distributed random variables on the unit circle that attract each other. (For comparison, the well-studied CβE involves n uniformly distributed random variables on the unit circle that repel each other.) We consider linear statistics of the
Background:: Accurate and internationally comparable human papillomavirus (HPV) testing services are essential for cervical cancer elimination programs. The WHO HPV Laboratory Network started issuing international HPV testing proficiency panels in 2008. Objectives:: We report the results of the 2019 global proficiency study and evaluate the proficiency over time. Study design:: The proficiency pan
HISA27/HISA35 VT 2025 Temakurs 2 Föremål i det förutna: Den medelda människans möte med ngen Människan är alltid omgiven av föremål, föremål som vi ser, äger, önskar att vi hade eller helst skulle vara utan. I och med den vetenskapliga och senare industriella revolutionen och massproduktionens tidevarv har vår syn på tingen förändrats på ett avgörande sätt jämfört med den hantverksbaserade medelti

Partially premixed combustion (PPC) is an advanced combustion strategy that has been proposed to provide higher efficiency and lower emissions than conventional compression ignition, as well as greater controllability than homogeneous charge compression ignition (HCCI). Stratification of the fuel-air mixture is the key to achieving these benefits. The injection strategy, injector-piston geometry d
Algorithms for secure encryption in a post-quantum world are currently receiving a lot of attention in the research community. One of the most promising such algorithms is the code-based scheme called QC-MDPC, which has excellent performance and a small public key size. In this work we present a very efficient key recovery attack on the QC-MDPC scheme using the fact that decryption uses an iterati
Zone plates are diffractive optics commonly used in X-ray microscopes. Here, we present a wet-chemical approach for fabricating high aspect ratio Pd/Si zone plate optics aimed at the hard X-ray regime. A Si zone plate mold is fabricated via metal-assisted chemical etching (MACE) and further metalized with Pd via electroless deposition (ELD). MACE results in vertical Si zones with high aspect ratio
Background: Popliteal artery aneurysm (PAA) carries a risk of sudden thromboembolism, resulting in acute limb ischemia (ALI). Since 2010, all 65 year-old-men in Region Skåne are invited for abdominal aortic aneurysm (AAA) screening, and subsequently for PAA if AAA is detected. The aims of the study were to explore if the ratio of PAAs treated electively compared with acute has changed since the im
Our investigation and analysis of public technology procurement has demonstrated that, as argued in Chapter 1 of this book, it is a concept with salient features. These distinguish it from other types of public procurement. With this particular type of procurement, policy makers are faced with new challenges. The reasons pursuing for public technology procurement, and consequently its processes an
Thoroughly considering and optimizing packaging systems can avoid food loss and waste. We suggest a number of issues that must be explored and review the associated challenges. Five main issues were recognized through the extensive experience of the authors and engagement of multiple stakeholders. The issues promoted are classified as follows: (1) identify and obtain specific data of packaging funThoroughly considering and optimizing packaging systems can avoid food loss and waste.

The dynamical processes associated with electric field manipulation of the polarization in a ferroelectric remain largely unknown but fundamentally determine the speed and functionality of ferroelectric materials and devices. Here we apply subpicosecond duration, single-cycle terahertz pulses as an ultrafast electric field bias to prototypical BaTiO3 ferroelectric thin films with the atomic-scale
Introduction: In Italy the course to become a general practitioner (GP) lasts 3 years and includes both theoretical and practical study. Different from the theoretical part, until recently the practical activity has not been assessed at all. The Emilia Romagna Regional Health Authority has developed a special program called INFORMEG (Management of Tutoring during the Triennial Specific Training in
To investigate why people live in areas at high risk of floods, a qualitative case study was carried out in the areas around Akuressa, in southwest Sri Lanka. Data col- lection consisted mainly of semistructured interviews with local residents and government officials. The purpose was to study why people live in areas at high risk of floods, by looking beyond the purely physical aspects of living
Background and purpose — Total hip arthroplasty (THA) is increasing as treatment of displaced femoral neck fractures. Several studies compare hemiarthroplasty (HA) with THA, but results vary and few studies report on medical complications. We examined the outcome of THA and HA with a focus on medical complications, hip complications, and death. Patients and methods — Data from the Swedish Hip Arth
BACKGROUND: Triage is widely used in the emergency department (ED) in order to identify the patient's level of urgency and often based on the patient's chief complaint and vital signs. Age has been shown to be independently associated with short term mortality following an ED visit. However, the most commonly used ED triage tools do not include age as an independent core variable. The aim of this
Electroactive polymers with time-dependent behavior are considered in the present paper by way of a new physics-based micromechanical model; such viscoelastic response is described by the internal evolution of the polymer network, providing a new viewpoint on the stress relaxation occurring in elastomers. The main peculiarity of such internally rearranging materials is their capacity to locally re
Background: Swedish studies on antibiotic use in primary care have been based on one-week registrations of infections. In order to study adherence to guidelines, analyses based on large databases that provide information on diagnosis linked prescriptions, are needed. This study describes trends in management of infections in Swedish primary care particularly with regards to antibiotic prescribing
As healthcare lacks incentives and structures for matching capacity between various care providers and for coordinating episodes of care, the result is capacity management that is difficult and uncertain. The organising of healthcare is not adapted to be able to assume the overall responsibility for the coordination of processes of care. The lack of coordination of care forms the departure point f
