Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Exploring the relations between regret, self-agency, and the tendency to repair using experimental methods and structural equation modeling [PDF]
, 2014 Previous studies suggest that feelings of regret are elicited by events appraised as goal incongruent and caused by the self, and that they are characterized by a tendency to repair the event.

Advanced Materials, EarlyView.Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Miniature Soft Robot With Magnetically Reprogrammable Surgical Functions
Advanced Materials, EarlyView.Miniature soft robots have great prospects to revolutionize minimally invasive treatments. Here we present a miniature soft robot, which can be reprogrammed to perform five surgical functionalities with six‐degrees‐of‐freedom motions. This soft robot can prospectively make minimally invasive surgery considerably safer and painless, and enable ...

Do they see it coming? Using expectancy violation to gauge the success of pedagogical reforms
Physical Review Special Topics. Physics Education Research, 2010 We present a measure, which we have named the Pedagogical Expectancy Violation Assessment (PEVA), for instructors to gauge one aspect of the success of their implementation of pedagogical reform by assessing the expectations and experiences of the ...

When It’s Okay That I Don’t Play: Social Norms and the Situated Construal of Social Exclusion [PDF]
, 2016 Being excluded and ignored has been shown to threaten fundamental human needs and cause pain. Such reflexive reactions to social exclusion have been conceptualized as direct and unmoderated (temporal need threat model of ostracism).

Muscle Control of an Extra Robotic Digit
Advanced Robotics Research, EarlyView.This study compares muscle‐ and movement‐based control for operating a supernumerary robotic thumb. While movement control performs better in the proposed tasks, muscle‐based (EMG) control promotes broader motor learning. The results highlight the promise and challenges of using biosignals for human augmentation, offering new insights into intuitive ...

Climate Change Threatens Micronutrient Density of European Winter Wheat
Advanced Science, EarlyView.Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates
