Abstract Theory suggests that natural selection against the production of unfit hybrids may
reinforce barriers to gene flow, eventually leading to reproductive isolation of differentiated …

Background After a transient ischemic attack (TIA) or minor stroke, the long-term risk of
stroke and other vascular events is not well known. In this follow-up to a report on 1-year …

Interbreeding between species (hybridization) typically produces unfit offspring. Reduced
hybridization should therefore be favored by natural selection. However, this is difficult to …

Teacher educators play an important role in preparing student teachers to integrate technology
into their classrooms. This article presents an overview of research literature on teacher …

Background: Intravenous thrombolysis (IVT) is a standard treatment for both anterior circulation
ischemic stroke (ACIS) and posterior circulation ischemic stroke (PCIS). PCIS is a clinical …

A new method to amplify the photon-axion conversions in a magnetic field is proposed using
a buffer gas at a specific pressure in a photon-regeneration experiment. As a first result, …

This paper reviews studies of peer feedback from the novel perspective of the providers of
that feedback. The possible learning benefits of providing peer feedback in online learning …

Global climate change has been shown to cause variable shifts in phenology in a variety of
animals and unexpected outcomes across food chains are to be found. Here we examined …

The temporal and spatial organization of the annual cycle according to local conditions is of
crucial importance for individuals’ fitness. Moreover, which sites and when particular sites …

Background Intravenous thrombolysis is considered to be the standard specific reperfusion
therapy in acute ischemic stroke in both anterior and posterior cerebral circulation. Aims Our …
