In recent years, new contributors to the marine silica cycle have emerged, including pico-sized phytoplankton (<2–3 µm in size) such as Synechococcus and picoeukaryotes. Their contribution and relevance to silica cycling are still under investigation. Field studies reporting the biogenic silica (bSi) standing stock in the pico-sized fraction are limited to silica-poor oligotrophic environments, an

It is becoming clear that the cognition of a species plays an important role in successful conservation, with cultural processes being a fundamental part of this. However, in contrast to mammals and birds, very little is known about cultural processes (and the social learning that underlies these) in reptiles. Here, we summarize the current state of knowledge, consider why this information is so l

We present the concept of our new high power laser facility Attohallen in Gothenburg, with focus on its first high-order harmonic generation beam line. The key specifications of this facility, including the architecture and operation of the femtosecond drive laser system, the XUV generation part of its first beam line for photon-demanding attosecond timing experiments in the energy range up to abo

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To assess the benefits and harms of motor interventions initiated prior hospital discharge to prevent neurodevelopmental and motor impairment in preterm infants compared to standard care, post-discharge motor interventions, and different modalities of the same motor intervention.

Organisation och ledarskap är viktiga ämnen som behandlar alltmer komplexa verkligheter – i dag räcker det inte med att producera resultat i form av produkter och tjänster, utan organisationer måste också leva upp till ett antal skilda krav om jämställdhet, hållbarhet och miljö samt förhålla sig till trender om vad som är gångbart inom olika organisationsområden. Denna bok ger en introduktion till

We report on an exact theory for ensembles of globally coupled, heterogeneous complex Riccati equations. A drastic dimensionality reduction to a few ordinary differential equations is achieved for Lorentzian heterogeneity. By applying this technique, we obtain low-dimensional firing-rate equations for populations of spiking neurons with a clustered substructure.

Uncertainty has long been discussed in social work as an inherent element of professional practice. The present paper extends this discussion into the realm of digital social work. It reports a study of anonymous text-based online counselling provided by the social services in Sweden. We explore what kind of uncertainty is evoked when social workers respond to anonymous users through online platfo

Chromosomal translocations are key events in cancer, driving oncogenesis by disrupting and deregulating critical genes. While specific tumor-associated translocations are well studied, the frequencies and distributions of most remain unknown. Additionally, the role of chromosomal reshuffling in translocations has received little attention. This study presents data on the chromosomal involvement in

The aim of this study was to investigate the impact of phenol on the precipitation of bovine serum albumin (BSA) and human growth hormone (hGH), in the presence of other excipients frequently used in biological drugs for parenteral delivery. The focus of the study lieson incompatibilities observed in multidose formulations containing non-ionic surfactants and preservatives. Previous research has s

To survive, animals have tuned their behaviors to the socio-environmental conditions offered by their habitats and communities. This also applies to communicative behaviors, which can be simultaneously constrained by a number of external factors. Hence, an animal’s surroundings narrow the optimal parameters for effective communication to well within the limits of what it is capable of producing. I

Establishing robust charging infrastructure is crucial for electric vehicle (EV) adoption. This study addresses the lack of systematic literature reviews examining the global charging infrastructure research landscape with a comprehensive review of English literature published between 2017 and 2023. We screened 12237 records, and analyzed 137 peer-reviewed and 31 grey literature studies. Findings

Combined density functional theory (DFT) and X-ray standing wave (XSW) studies have previously provided evidence for the preferential adoption of an inverted conformation of 2H-TPP on Cu(111) in contrast to the saddle conformation usually favored by porphyrin molecules adsorbed on metals. We experimentally demonstrate, via X-ray photoelectron spectroscopy (XPS) analysis, that the binding energies

Cancer cells in solid tumors experience hypoxia, a condition of low O2 concentration, since their O2 demand exceeds the supply from the surrounding vasculature. However, how these cells adapt to hypoxia requires further elucidation. Here, we use a transparent phosphorescent thin film to visualize the self-generated hypoxia field of prostate cancer cells and quantify local O2 consumption rates, mea
