We demonstrate how the individual mirrors of a high-quality Kirkpatrick-Baez (KB) mirror system can be aligned to each other to create an optimally focused beam, through minimizing aberrations in the phase of the ptychographically reconstructed pupil function. Different sources of misalignment and the distinctive phase artifacts they create are presented via experimental results from the alignment

Background: Birds that forage while covering distance during migration should adjust traveling behaviors as the availability of foraging habitat changes. Particularly, the behavior of those species that depend on bodies of water to find food yet manage to migrate over changing landscapes may be limited by the substantial variation in feeding opportunities along the route. Methods: Using GPS tracki

Spontaneous magnetic alignment is the simplest known directional response to the geomagnetic field that animals perform. Magnetic alignment is not a goal directed response and its relevance in the context of orientation and navigation has received little attention. Migratory songbirds, long-standing model organisms for studying magnetosensation, have recently been reported to align their body with

BACKGROUND: This aggregated population study investigated the impact of the seemingly quasi-randomly assigned school winter holiday in weeks 6-10 (February to early March) on excess mortality in 219 European regions (11 countries) during the COVID-19 pandemic in the spring 2020. A secondary aim was to evaluate the impact of government responses to the early inflow of infected cases. METHODS: Data

Objective: To investigate the risk of stillbirth or neonatal death before 45 post-menstrual weeks in relation to gestational duration, stratified by body mass index (BMI) and parity. Design: Retrospective study. Setting: Data from the Swedish Medical Birth Register. Population: Singleton, cephalic births at between 39+0 and 42+2 weeks of gestation, 2005–2016 (n = 892 339). Methods: Relative risk r

In this conceptual paper we reimagine the Capitalocentric present. To do so, we (1) critique corporate fantasies about ethical consumption; (2) offer alternative relational ethics of consumption, with special attention to concrete neo-animist practices to imagine alternative futures to the Capitalocentric present, and (3) invite imaginative theorization as a bridge between present and future.In this conceptual paper we reimagine the Capitalocentric present.

For theologians such as Karl Barth the support for Germany’s militaristic ambitions and actions voiced in the manifesto "An die Kulturwelt", published in 1914, was a consequence of the historicization of theology. Ernst Troeltsch (1865-1923), whose interdisciplinary thinking revolved around the significance of history for theology, was labeled the theologian of historicism. Although he had not sig

Los Angeles Islands är ett konstnärligt forskningsprojekt om arkitektonisk amerikanitet i en svensk region.Los Angeles läggs som ett raster över Malmö. Los Angeles och USA:s västkust har utvecklats till en superprojicering av övriga världens föreställningar om den amerikanska kontinenten.
