Thinking and feeling about novelty: How cognition and emotion shape investment in novel ideas

Strategic Management Journal, Volume 47, Issue 8, Page 2208-2234, August 2026.
Abstract While prior research on the strategic framing of innovation highlights the cognitive mechanisms underlying novelty evaluation, we know little about the corresponding emotional mechanisms. Drawing on appraisal theory, construal level theory, and the literature on emotions, we theorize two distinct appraisal‐emotion pathways through which the ...

Satellite Quantum Communications When Man-in-the-Middle Attacks Are Excluded

Entropy, 2019
An application of quantum communications is the transmission of qubits to create shared symmetric encryption keys in a process called quantum key distribution (QKD). Contrary to public-private key encryption, symmetric encryption is considered safe from (

Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces

InfoMat, Volume 8, Issue 7, July 2026.
A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Security‐Enhanced Differential Binary‐Phase‐Shift‐Keying Quantum Key Distribution With a Wavelength‐Switchable Single‐Photon Carrier

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...
