High-performance polymer donors when paired with nonfullerene acceptors are mainly limited to flanking halogenated benzodithiophene (BDT)-based π-conjugated copolymers, which however involve complex synthetic procedures. Herein, a series of halogen-free polymer donors that link BDT moiety with two highly electron-deficient benzodithiophene-dione (BDD) and diketopyrrolopyrrole (DPP) units with vari

Orientation towards application, transdisciplinarity and social distribution are prominent ideas when policy prescribes how to conduct research on complex, real-world issues. Issues dealt with in ageing research are both epistemologically complex and politically contentious. By using the metaphor of ‘travelling ideas,' we have followed these ideas on their journey into 17 approved grant proposals

This study investigates factors of importance for tadpoles survival and metamorph production in the common frog Rana temporaria. It also assess the importance of this for the population dynamics of the species. Eighteen ponds were studied for up to 8 years. Data collected each year included: number of spawn clumps deposited, tadpole number and metamorph number. The permanency of the ponds was also

Purpose: To assess the associations of meniscal tears, knee malalignment, cartilage damage, knee effusion, and body mass index with meniscal extrusion. Materials and Methods: The Multicenter Osteoarthritis study is an observational study of individuals who have or are at risk for knee osteoarthritis (OA). The HIPAA-compliant protocol was approved by the institutional review boards of all particip

Abstract in German Alles in allem eine Anthologie, die in Detailfragen durchaus aktuellste Forschungsergebnisse vorweisen kann, aber von einer annähernd vollständigen Forschungsübersicht zur Thematik „Musik und Nationalsozialismus“ weit entfernt ist, und auch nicht mit den in Monographien vorgelegten Forschungsergebnissen der Autorinnen und Autoren mithalten kann.

To identify from a patient's perspective, difficulties and differences in the comprehension of five global presenteeism measures in patients with inflammatory arthritis and OA across seven countries.

Objective: An association between small for gestational age (SGA) and risk for celiac disease (CD) in childhood has previously been reported. However, this association may reflect residual confounding by genetic or environmental factors. For example, presence of subclinical CD in the mother might be a common cause of both SGA and CD in the offspring. We investigate whether SGA is causally associat

Increased intima-media thickness (IMT) has been shown to predict cardiovascular risk, and measurement of intima-media thickness has been extensively used in medical research since the mid-1990s. IMT is conventionally measured by manual tracing, however this method is very time-consuming and suffers from large inter-observer variability. Numerous methods, both semi-automatic and fully-automatic, ha
