Natural and anthropogenic forcings lead to contrasting vegetation response in long-term vs. short-term timeframes

Understanding vegetation response to natural and anthropogenic forcings is vital for managing watersheds as natural ecosystems. We used a novel integrated framework to separate the impacts of natural factors (e.g. drought, precipitation and temperature) from those of anthropogenic factors (e.g. human activity) on vegetation cover change at the watershed scale. We also integrated several datasets i

Linear and nonlinear trend analyses in global satellite‐based precipitation, 1998‐2017

Precipitation varies spatiotemporally in amount, intensity, and frequency. Although, much research has been conducted on analyzing precipitation patterns and variation at the global scale, trend types have still not received much attention. This study developed a new polynomial‐based model for detecting non‐linear and linear trends in a satellite precipitation product (TRMM 3B43) for the 1998‐2017

Extended theoretical transition data in C I-IV

Accurate atomic data are essential for opacity calculations and for abundance analyses of the Sun and other stars. The aim of this work is to provide accurate and extensive results of energy levels and transition data for C i–iv. The Multiconfiguration Dirac–Hartree–Fock and relativistic configuration interaction methods were used in this work. To improve the quality of the wavefunctions and reduc

Bacteremic sepsis leads to higher mortality when adjusting for confounders with propensity score matching

One can falsely assume that it is well known that bacteremia is associated with higher mortality in sepsis. Only a handful of studies specifically focus on the comparison of culture-negative and culture-positive sepsis with different conclusions depending on study design. The aim of this study was to describe outcome for critically ill patients with either culture-positive or -negative sepsis in a

Lärande utvärdering som verktyg för förändring? : Erfarenheter från en utvärdering av Maria Nordvästs samverkansprocess

Maria Nordväst (MN) är en integrerad verksamhet i Helsingborg som omfattar fyra kommuner samt Region Skånes Vuxenpsykiatri och Barn- och ungdomspsykiatri. MN har som uppgift att erbjuda rådgivning och behandling till unga upp till 25 år som har problem med alkohol och/eller andra droger. I samband med uppstarten av verksamheten år 2013 genomfördes en lärande utvärdering. Syftet var att utvärdera h

Towards a Meeting of Minds? : When Participatory Researchers engage with a Health Care Community of Practice

A collaborative action research initiative was conducted in collaboration with professionals in a set of clinical research and development networks in a local health care system in Sweden. This is an examination of the interaction between engaging in collaborative action research practice and the power of tradition in health care.

Regional differences in how related variety ‘works’: the case of labour mobility

The benefits of related variety on regional employment growth have become a prevailing view. However, these remain potential benefits unless channels (e.g. labour flows, inter-firm cooperation) and regional capabilities are in place to convert them into actual growth. This paper focuses on the labour mobility channel and proposes a way to measure the realized part of related variety. It demonstrat

Risk Factors for Syncope Associated With Multigenerational Relatives With a History of Syncope

Importance: Reflex syncope is the major cause of transient loss of consciousness, which affects one-third of the population, but effective treatment for individuals with severe syncope is lacking. Better understanding of reflex syncope predisposition may offer new therapeutic solutions.Objectives: To determine the familial risk of syncope in first-, second-, and third-degree relatives of affected

Risk factors for need of reoperation in bilateral chronic subdural haematomas

Background: Chronic subdural haematoma (CSDH) is one of the most common neurosurgical diseases. A subtype of CSDH is bilateral chronic subdural haematoma (bCSDH) which represents 20-25% of patients with CSDH and has a higher recurrence rate. There is no clear consensus on how bCSDH should be treated regarding upfront unilateral- or bilateral evacuation of both haematomas. The purpose of this study

Formative period in the x-ray-induced photodissociation of organic molecules

Absorption of x-ray photons by atomic inner shells of light-element organics and biomolecules often leads to formation of dicationic electronic states and to molecular fragmentation. We investigated the x-ray-induced dissociation landscape of a representative medium-sized organic molecule, thiophene, by femtosecond x-ray pulses from the Super Photon Ring-8 GeV (SPring-8) Angstrom Compact Free-Elec

Acute myeloid leukemia in patients we judge as being older and/or unfit

Definition of older age in AML is arbitrary. In the context of the clinical studies, it starts with age ≥ 60 or ≥65 years and in recent years ≥70 or 75, depending on the selection of the studied population. In clinical practice, with older age we often mean that the patient is unfit for intensive chemotherapy. Higher age overlaps with categories such as worse performance status, unfitness, co-morb

Improved low-frequency performance of cross-laminated timber floor panels by informed material selection

The paper demonstrates improved structural low-frequency vibroacoustic performance of cross-laminated timber (CLT) floor panels by informed selection of the wood material. The use of wood species and strength classes that are not traditionally assigned to CLT panels was investigated in order to study their influence on dynamic characteristics and vibroacoustic response metrics. The potential of ea
