In this paper we study the convex envelopes of a new class of functions. Using this approach, we are able to unify two important classes of regularizers from unbiased non-convex formulations and weighted nuclear norm penalties. This opens up for possibilities of combining the best of both worlds, and to leverage each method’s contribution to cases where simply enforcing one of the regularizers are

Epidemics and pandemics have shaped human history and will continue to do so. The COVID-19 crisis has shown that there is need to understand how Europe can ensure better management of and preparedness for them. This joint advice builds on lessons learned from the current and from previous pandemics. It analyses their complexity, drawing on insights from research and scholarship and taking European

Objective: To examine the prevalence of dysnatraemias among children admitted for paediatric surgery before and after a change from hypotonic to isotonic intravenous maintenance fluid therapy. Design: Retrospective consecutive time series intervention study. Setting: Paediatric surgery ward at the Children's Hospital in Lund, during a 7-year period, 2010-2017. Patients: All children with a blood s

Background: Reducing the need for hospitalisation in patients with chronic obstructive pulmonary disease (COPD) is an important goal in COPD management. The aim of this study was to evaluate re-hospitalisation, treatment, comorbidities and mortality in patients with COPD who were hospitalised for the first time due to a COPD exacerbation. Methods: This was a retrospective, population-based observa

This reviewe of Land Use Land Cover Change (LULCC) studies in Uganda indicate agriculture, forest, grassland, and woodland as the major land use and land cover types. Central Uganda is the most studied region (15%), followed by western (14), eastern (10), and northern Uganda (3). District scale studies were (48%), catchment (19%), forest (17%), national (10%), and park (7%). Landsat 30 m and remot

För att mildra förlusten av biologisk mångfald i jordbruksmarker, inklusive dess pollinatörer, har många ansträngningar ägnats åt att bevara naturbetesmarker och slåtterängar. Dock är redan förlorade naturbetesmarker och slåtterängar svåra att återställa och kostsamma att hantera för ökade fördelar för biologisk mångfald. Dessutom är idag många marker som tidigare användes till slåtterängar nu betTo mitigate loss of farmland biodiversity, including insect pollinators, much effort has been spent on preserving semi-natural grasslands. However, already lost grasslands are difficult to restore and costly to manage for increased benefits to biodiversity. Previously often mowed semi-natural grasslands are today mostly managed by grazing, resulting in a lack of critical floral resources for many

Water supply security is increasingly becoming a challenge worldwide. Surface waters, which are often used for drinking water production, have experienced an increase in natural organic matter (NOM) and frequency of algae blooms. Water quantity is also an issue due to increasing populations and potable water demand. As a result, unsustainable extraction of surface and groundwater has led to low wa

Large-eddy simulations with a transported probability density function model coupled with a finite-rate chemistry is applied to study the ignition process of an n-heptane spray in a constant volume chamber with a premixed methanol-air atmosphere under conditions relevant to reactivity controlled compression ignition (RCCI) engines. Three reacting spray cases with initial methanol-air equivalence r

Down to a cathodic potentials of -1.20 V versus the reversible hydrogen electrode, the structure of IrO2(110) electrodes supported by TiO2(110) is found to be stable by in situ synchrotron-based X-ray diffraction. Such high cathodic potentials should lead to reduction to metallic Ir (Pourbaix diagram). From the IrO2 lattice parameters, determined during cathodic polarization in a H2SO4 electrolyte

Power can be applied in different domains (e.g., politics, work, romantic relationships, family etc.), however, we do not always reflect on which domains we have power in and how important power in these domains is. A dominant idea is that men have more power than women. This notion may be biased because the concept of power is associated with public life. We introduce the concept of preference-we

While agrarian change has been a recurrent theme in Ghana’s endeavor for economicdevelopment, questions on how land resources should be managed to ensure prompt attainment of economic growth remain unanswered. In Ghana, land is controlled by customary actors, while the state is the custodian of agricultural policies. The need for interaction between the two actors to ensure that the envisioned eco

Adherence to national and international clinical practice guidelines is suboptimal throughout Europe. The European Association of Urology Guidelines Office project “IMAGINE” (IMpact Assessment of Guidelines Implementation and Education) has been developed to measure baseline adherence to urological guideline recommendations across Europe and to identify issues that drive nonadherence.

In this work, a fast and efficiently design method has been introduced. This design process consists of the overall design and the detailed design. For the overall design, one-dimensional pipe-network computations are employed to obtain several design cases quickly at the beginning. Meanwhile the solid domain geometry and mesh with cooling structures, i.e., film holes, impingement holes, and ribs

Diel vertical migration (DVM) is the most common behavioral phenomenon in zooplankton, and numerous studies have evaluated DVM under strong seasonality at higher latitudes. Yet, our understanding of the environmental drivers of DVM at low latitudes, where seasonal variation is less pronounced, remains limited. Therefore, we here examined patterns of vertical distribution in copepods in six subtrop

Osmoderma eremita is a species of beetle that inhabits hollows in ancient trees, which is a habitat that has decreased significantly during the last century. In southeastern Sweden, we studied the metapopulation dynamics of this beetle over a 25 year period, using capture-mark-recapture. The metapopulation size had been rather stable over time, but in most of the individual trees there had been a

Socioeconomic development initiatives (SDIs) have become a controversial issue. In giving skill trainings and credit supports, practitioners assume that SDI participation will enhance women’s income/dignity. Some studies have indicated that SDIs reduce women’s exposure to marital violence (MV), while others have shown that they increase spousal conflicts/MV. Our study explains how SDI participatio

The polymerase chain reaction (PCR) is a very powerful method to detect and identify pathogens. The high sensitivity of the method, however, comes with a cost; any of the millions of artificial DNA copies generated by PCR can serve as a template in a following experiment. If not identified as contaminations, these may result in erroneous conclusions on the occurrence of the pathogen, thereby infla

Clinical trial results have recently demonstrated that inhibiting inflammation by targeting the interleukin-1β pathway can offer a significant reduction in lung cancer incidence and mortality, highlighting a pressing and unmet need to understand the benefits of inflammation-focused lung cancer therapies at the genetic level. While numerous genome-wide association studies (GWAS) have explored the g
