Through Rested Eyes: The Relevance of Sleep for Dynamic Changes and Stable Differences in Employees' Stress Appraisals

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Even though stress appraisals determine employees' states and behaviors at work, knowledge of their antecedents is limited. This research project integrates sleep research into the transactional stress theory to explain how sleep, as a key factor shaping employees' resource availability, relates to employees' appraisals of their job demands ...

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

open access: yesLaser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

Nonlocal Leaky Mode Metasurfaces for Mode‐, Angle‐, and Polarization‐Multiplexed Holography With Thermal Light

open access: yesLaser &Photonics Reviews, EarlyView.
Nonlocal leaky mode metasurfaces reconstruct multiplexed holograms directly from unfiltered thermal light. High‐Q leaky guided modes compress broadband halogen emission into narrowband channels, enhancing temporal coherence a hundredfold, while a single nanohole array encodes independent images addressed by mode, angle, and polarization, establishing ...

On the Nonnegative Rank of Positive Operators

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT In this paper, we introduce the concept of a nonnegative rank of a positive operator T:X→Y$T: X\rightarrow Y$ between ordered vector spaces. In the case of nonnegative matrices, our definition agrees with the standard definition of a nonnegative rank.
