Fungerar politiken för ett renare Östersjön?
Trots att jordbrukets näringsutsläpp till Östersjön har minskat krävs mycket mer för att uppnå de uppsatta miljömålen. Vi har utvärderat politiken som används för att minska utsläppen från de nio länder som samarbetar om restaureringen av Östersjön. Vi finner att den nuvarande politiken är otillräcklig eftersom:Många länder har inte genomfört de utlovade åtgärderna för att minska näringsutsläpp fr
Cellular Aging Secretes : a Comparison of Bone-Marrow-Derived and Induced Mesenchymal Stem Cells and Their Secretome Over Long-Term Culture
Mesenchymal stem cells (MSCs) hold promising therapeutic potential in several clinical applications, mainly due to their paracrine activity. The implementation of future secretome-based therapeutic strategies requires the use of easily accessible MSCs sources that provide high numbers of cells with homogenous characteristics. MSCs obtained from induced pluripotent stem cells (iMSCs) have been put
Styrmedel för minskad antibiotikaanvändning
Antibiotikaresistens innebär att bakterier blir motståndskraftiga mot antibiotika. Det är ett växande globalt problem eftersom möjligheten att behandla och bota infektioner minskar i takt med att antibiotikaresistensen ökar. En av orsakerna till resistensproblematiken är felaktig användning av antibiotika vid djuruppfödning. Exempelvis ges antibiotika inte endast vid behov utan i tillväxtbefrämjan

Search for events with a pair of displaced vertices from long-lived neutral particles decaying into hadronic jets in the ATLAS muon spectrometer in pp collisions at s =13 TeV
A search for events with two displaced vertices from long-lived particle (LLP) pairs using data collected by the ATLAS detector at the LHC is presented. This analysis uses 139 fb-1 of proton-proton collision data at s=13 TeV recorded in 2015-2018. The search employs techniques for reconstructing vertices of LLPs decaying to jets in the muon spectrometer displaced between 3 and 14 m with respect to

A five-year follow-up of ABCA4 carriers showing deterioration of retinal function and increased structural changes
Purpose: To investigate whether the reduced retinal function and morphological retinal changes previously demonstrated in ABCA4 carriers had remained stationary or had deteriorated over time at 5-year follow-up to further explore if carriers of an autosomal recessive trait also express a weak phenotype, although this is not expected for an autosomal recessive disorder. Methods: Thirteen ABCA4 carr
ISHLT consensus statement: Perioperative management of patients with pulmonary hypertension and right heart failure undergoing surgery
Pulmonary hypertension (PH) is a risk factor for morbidity and mortality in patients undergoing surgery and anesthesia. This document represents the first international consensus statement for the perioperative management of patients with pulmonary hypertension and right heart failure. It includes recommendations for managing patients with PH being considered for surgery, including preoperative ri
Sub-cycle high-order nonlinearities in a terahertz quantum cascade laser
Ultrafast electron dynamics in quantum cascade lasers hold enormous potential for the implementation of intense, compact mode-locked terahertz sources, squeezed terahertz light, frequency mixers, and comb-based metrology systems. Yet the important sub-cycle dynamics have been notoriously difficult to access in operational terahertz quantum cascade lasers. Here we show the first field-resolved two-
Airbnb and the sharing economy
A large share of growth in the sharing or platform economy is driven by peer-to-peer (P2P) accommodation providers such as Airbnb. The literature argues for both positive and negative socio-cultural, economic and environmental impacts emanating from the tourism and hospitality businesses and value chains that are dependent on AirBnB and other online platforms. These impacts are felt in terms of co
Exogenous shocks, Covid 19 and firms' ability to learn, adapt and evolve
In the context of the exponential growth of data, the Covid 19 pandemic and the need for quick adaptation faced by companies, as well as by society at large, the concept of organisational learning is flourishing and becoming an even more critical component of organisational survival and growth. This study applies a socio-technical lens to shed light on the organisational learning processes taking
Negative vaccine voices in Swedish social media
Vaccinations are one of the most significant interventions to public health, but vaccine hesitancy creates concerns for a portion of the population in many countries, including Sweden. Since discussions on vaccine hesitancy are often taken on social networking sites, data from Swedish social media are used to study and quantify the sentiment among the discussants on the vaccination-or-not topic du
A novel neo-sex chromosome in Sylvietta brachyura (Macrosphenidae) adds to the extraordinary avian sex chromosome diversity among Sylvioidea songbirds
We report the discovery of a novel neo-sex chromosome in an African warbler, Sylvietta brachyura (northern crombec; Macrosphenidae). This species is part of the Sylvioidea superfamily, where four separate autosome–sex chromosome translocation events have previously been discovered via comparative genomics of 11 of the 22 families in this clade. Our discovery here resulted from analyses of genomic
Transient multi-THz spectroscopy of single and multilayer 2D perovskite single crystals
With air-photonics THz platform, we investigated photo-induced carrier dynamics of single and multilayer 2D perovskite single crystals. Interesting novel features and physics are revealed with effective conductivity spectrum up to 12 THz and 40-fs time resolution.
Deep profiling of multiple ischemic lesions in a large, multi-center cohort: Frequency, spatial distribution, and associations to clinical characteristics
Background purpose: A substantial number of patients with acute ischemic stroke (AIS) experience multiple acute lesions (MAL). We here aimed to scrutinize MAL in a large radiologically deep-phenotyped cohort. Materials and methods: Analyses relied upon imaging and clinical data from the international MRI-GENIE study. Imaging data comprised both Fluid-attenuated inversion recovery (FLAIR) for white

On negative eigenvalues of the spectral problem for water waves of highest amplitude
We consider a spectral problem associated with steady water waves of extreme form on the free surface of a rotational flow. It is proved that the spectrum of this problem contains arbitrary large negative eigenvalues and they are simple. Moreover, the asymptotics of such eigenvalues is obtained.
