Components of local adaptation and divergence in pollination efficacy in a coevolving species interaction

Selection leading to adaptation to interactions may generate rapid evolutionary feedbacks and drive diversification of species interactions. The challenge is to understand how the many traits of interacting species combine to shape local adaptation in ways directly or indirectly resulting in diversification. We used the well-studied interactions between Lithophragma plants (Saxifragaceae) and Grey

Rapid Profiling of Protein Complex Reorganization in Perturbed Systems

Protein complexes constitute the primary functional modules of cellular activity. To respond to perturbations, complexes undergo changes in their abundance, subunit composition, or state of modification. Understanding the function of biological systems requires global strategies to capture this contextual state information. Methods based on cofractionation paired with mass spectrometry have demons

Closing Data Gaps and Paving the Way for Pan-European Fire Safety Efforts : Part II—Terminology of Fire Statistical Variables

A well-defined terminology of fire-related variables is important for correct analyses and supporting knowledge-based decisions regarding the evaluation of building fires at the European level. After developing an overview of current practices for fire statistics in Part I, the terminology used and the data collected by the EU Member States and eight other countries regarding fire incidents, prope

Room temperature X-ray absorption spectroscopy of metalloenzymes with drop-on-demand sample delivery at XFELs

X-ray crystallography and X-ray spectroscopy using X-ray free electron lasers plays an important role in understanding the interplay of structural changes in the protein and the chemical changes at the metal active site of metalloenzymes through their catalytic cycles. As a part of such an effort, we report here our recent development of methods for X-ray absorption spectroscopy (XAS) at XFELs to

Revisiting the notion of the public library as a meeting place : challenges to the mission of promoting democracy in times of political turmoil

Purpose: This article explores how public librarians understand and perform the democratic mission of public libraries in times of political and social turbulence, and critically discusses the idea of public libraries as meeting places.Methodology: Five group interviews conducted with public librarians in southern Sweden are analyzed using a typology of four perspectives on democracy.Findings: TwoPurposeThis article explores how public librarians understand and perform the democratic mission of public libraries in times of political and social turbulence and critically discusses the idea of public libraries as meeting places.Design/methodology/approachFive group interviews conducted with public librarians in southern Sweden are analyzed using a typology of four perspectives on democracy.Fi

Assessing the use of clinical guidelines against domestic violence in southern Sweden : A mixed-methods study

Background and Aim: Domestic violence is a prevalent public health issue. While clinical guidelines and care programs for its identification and handling have been formulated in all administrative regions of Sweden, their degree of implementation is largely unknown. This study aims to assess the implementation of one administrative region's care program, including how it is seen to align with and

A new animal product free defined medium for 2D and 3D culturing of normal and cancer cells to study cell proliferation and migration as well as dose response to chemical treatment

Cell culturing methods are increasingly used to reduce and replace the use of live animals in biomedical research and chemical toxicity testing. Although live animals are avoided when using cell culturing methods, they often contain animal-derived components of which one of the most commonly used is foetal bovine serum (FBS). FBS is added to cell culture media among other supplements to support ce

Requirements Engineering for Automotive Perception Systems : An Interview Study

Background: Driving automation systems (DAS), including autonomous driving and advanced driver assistance, are an important safety-critical domain. DAS often incorporate perceptions systems that use machine learning (ML) to analyze the vehicle environment. Aims: We explore new or differing requirements engineering (RE) topics and challenges that practitioners experience in this domain. Method: We

Free Radical Polymerization of Dimethyl Amino Ethyl Methacrylate Initiated by Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) Macroazo Initiator : Thermal and Physicochemical Characterization

A novel macro intermediate based on poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) was synthesized for use in the copolymerization with dimethyl amino ethyl methacrylate (DMAEMA). Methyl amino ethanol was reacted with PHBHHx to prepare a dihydroxy terminated polyester. The hydroxyl ends of the obtained PHBHHx derivatives were capped with 4,4’-azobis cyanopentanoic acid to obtain the PHBHHx

Fountain of youth—Targeting autophagy in aging

As our society ages inexorably, geroscience and research focusing on healthy aging is becoming increasingly urgent. Macroautophagy (referred to as autophagy), a highly conserved process of cellular clearance and rejuvenation has attracted much attention due to its universal role in organismal life and death. Growing evidence points to autophagy process as being one of the key players in the determ
