Entangled phenomenologies
Maximilian Gregor Hepach
Nov 01, 2021
This article calls into question recent attempts to move beyond, to ‘post’ phenomenology by highlighting the continued relevance of key phenomenological concepts (intentionality and correlationism) for human geography. I show...
Neural correlates of conversion disorder
BACKGROUND: Conversion Disorders (CD) are prevalent functional disorders. Although the pathogenesis is still not completely understood, an interaction of genetic, neurobiological, and psychosocial factors is quite likely. The...

Anita Siller, Lisa Seekircher, Gregor A Wachter, Manfred Astl, Lena Tschiderer, Bernhard Pfeifer, Manfred Gaber, Harald Schennach, Peter Willeit
Apr 25, 2022
There is uncertainty about the seroprevalence of anti-SARS-CoV-2 antibodies in the general population of Austria and about the waning of antibodies over time. We conducted a seroepidemiological study between June 2020 and...
Neural correlates of somatoform disorders from a meta-analytic perspective on neuroimaging studies.
Somatoform disorders (SD) are common medical disorders with prevalence rates between 3.5% and 18.4%, depending on country and medical setting. SD as outlined in the ICD-10 exhibits various biological, social, and psychological...

Microscopic origin of entropy-driven polymorphism in hybrid organic-inorganic perovskite materials
Entropy is a critical, but often overlooked, factor in determining the relative stabilities of crystal phases. The importance of entropy is most pronounced in softer materials, where small changes in free energy can drive...
Tuning the Mechanical Response of Metal−Organic Frameworks by Defect Engineering
Stefano Dissegna, Pia Vervoorts, Claire Hobday, Tina Duren, Dominik Daisenberger, Andrew Smith, Roland A Fischer, Gregor Kieslich
Sep 19, 2018
The incorporation of defects into crystalline materials provides an important tool to fine-tune properties throughout various fields of materials science. We performed high-pressure powder X-ray diffraction experiments...
The relationship between eye movement and vision develops before birth.
Veronika Schöpf, Thomas Schlegl, Andras Jakab, Gregor Kasprian, Ramona Woitek, Daniela Prayer, Georg Langs
Jan 02, 2019
While the visuomotor system is known to develop rapidly after birth, studies have observed spontaneous activity in vertebrates in visually excitable cortical areas already before extrinsic stimuli are present. Resting state...
Scene memory and spatial inhibition in visual search
Raul Grieben, Jan Tekülve, Stephan KU Zibner, Jonas Lins, Sebastian Schneegans, Gregor Schöner
Feb 10, 2021
Any object-oriented action requires that the object be first brought into the attentional foreground, often through visual search. Outside the laboratory, this would always take place in the presence of a scene representation...
