Fitting a matrix of a given rank to data in a least squares sense can be done very effectively using 2nd order methods such as Levenberg-Marquardt by explicitly optimizing over a bilinear parameterization of the matrix. In contrast, when applying more general singular value penalties, such as weighted nuclear norm priors, direct optimization over the elements of the matrix is typically used. Due t

The seeking of potential rents directs flows of investment into built and natural environments, suffusing volatility into urban and rural landscapes, generating gentrification and other forms of land use change, and displacing lives and livelihoods to make space for ‘improvement’, ‘highest and best use’, ‘revitalization’, or the like. In this paper we argue that potential rents are captured at the

Internationally coordinated censuses of Whooper Swans Cygnus cygnus across continental northwest Europe were undertaken in mid-winter 1995, 2000, 2005, 2010 and 2015. The estimate of 138,500 birds in 2015, the highest to date, represented a more than doubling of the population size (at an annual increase of 4.1%) since the first census total of 59,000 swans in 1995. The largest increase was in Den

Motivated by experimental findings on deformation induced microcracks in thin metal films and by their influence on the effective macroscopic electrical conductivity, a computational multiscale formulation for electrical conductors is proposed in this contribution. In particular, averaging theorems for kinematic quantities and for their energetic duals are discussed, an extended version of the Hil

Background: There is little focus on adults with cerebral palsy (CP) in research and health care and insufficient knowledge on how to identify and manage pain in this population. Objectives: This systematic review and meta-analysis aimed to determine whether pain prevalence in adults with CP is high and to explore variations in pain prevalence of subgroups, pain locations, pain severity and pain i

An ecofriendly design of low-cost electrochemical sensor activated by low-grade photo-thermal energy can be a prime stepping-stone for the perspective developments of various renewable energy conversion and utilization schemes. In this study, an investigation of n-type indium arsenide (n-InAs)/aqueous solution of orange dye (OD)/Zinc (Zn) sensor was carried out at various molarities of 1, 2, and 3

Objective. To construct a Frailty Index (FI) as a measure of vulnerability to adverse outcomes among patients with systemic lupus erythematosus (SLE), using data from the Systemic Lupus International Collaborating Clinics (SLICC) inception cohort. Methods. The SLICC inception cohort consists of recently diagnosed patients with SLE followed annually with clinical and laboratory assessments. For thi

The early life human gut microbiota exerts life-long health effects on the host, but the mechanisms underpinning its assembly remain elusive. Particularly, the early colonization of Clostridiales from the Roseburia-Eubacterium group, associated with protection from colorectal cancer, immune- and metabolic disorders is enigmatic. Here, we describe catabolic pathways that support the growth of Roseb

Background and purpose — Modular-neck hip stems have been identified with corrosion-related problems from the neck–stem junction. We report an ongoing varus deformity of modular-neck hip stems with simultaneous metal ion release observed during a study comparing the migration of modular vs. standard hip stems. Patients and methods — We followed 50 patients with modular and 25 with standard neck st

In this work, atmospheric pollutant emissions of NOx, SOx, CO, particulate matter (PM), total organic compounds (TOC), and CO2 from larger stationary sources of pollutants in Brazil were inventoried and spatialized over the whole Brazilian territory for the base year 2011. The developed inventory comprises a total of 16 refining units, 1730 thermoelectric power plants (TPPs), 96 cement industries,

In this paper, the flame-wall interaction of reacting diesel spray under engine like conditions is investigated using large eddy simulations. The aim of this study is to understand the influence of the distance between the wall and the spray nozzle on the air entrainment rate, which is a key variable in formation/oxidation process of soot. Three experimental cases are investigated, a free jet case

Standardised data formats and data models are essential for data integration and interoperability, which in turn adds value to data by allowing its reuse in multiple contexts. For this reason, in recent years extensive efforts have been focused on standards development. When representing the built environment, 3D city models and Building Information Models are particularly relevant, and their inte

Aims: Low-risk status in pulmonary arterial hypertension (PAH) predicts better survival. The present study aimed to describe changes in risk status and treatment approaches over multiple clinical assessments in PAH, taking age and comorbidity burden into consideration. Methods and results: The study included incident patients from the Swedish PAH registry, diagnosed with PAH in 2008–2019. Group A

Aim: To assess the quality of life in frail older persons (65+ years) living in nursing homes and to examine differences between quality of life perceptions among different gender and age groups. Design: Cross-sectional. Methods: Data were collected during 2015-2017 based on two questionnaires (WHOQOL-OLD and WHOQOL-BREF). Seventy-eight older persons living in nursing homes in southern Sweden answ

Kobber er et forhistorisk produkt som fortsatt produseres. Produksjonsmetodene og bruksområdene har blitt radikalt forandret mange ganger, og metallet stod sentralt i fremveksten av den moderne verdensøkonomien. I tidlig moderne tid var Skandinavia lenge den største produsenten av kobber i Europa, spesielt gjennom kobberanleggene i Falun i Sverige og på Røros i Norge. Likevel har metallet ofte bli
