Operating in perpetual motion? Coping with the dark side of global boundary spanning

Global Strategy Journal, EarlyView.
Abstract Research Summary This paper explores how individuals experience and cope with the demands of global boundary spanning in multinational enterprises (MNEs). We foreground temporary colocation as a modality through which mobile global boundary spanners repeatedly traverse multiple boundaries, triggering intense demands with adverse consequences ...

Multi frame holograms batched optimization for binary phase spatial light modulators

Scientific Reports
Phase retrieval methods used in computer generated holograms such as Gerchberg-Saxton and gradient descent give results which are prone to noise and other defects.

Clinical Applications of 3D Specimen Scanning and Margin Mapping in Musculoskeletal Oncology: A 36 Patient Case Series

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background Text‐based pathology reports inadequately communicate complex three‐dimensional (3D) relationships in musculoskeletal oncology, potentially contributing to errors in re‐resection and adjuvant treatment planning. While our prior 7‐case pilot study established technical feasibility, the scalability of this workflow and its utility as ...

A Reversible Clearing Strategy Enables Robust Label‐Free Phase Imaging of Thick Tissues

Laser &Photonics Reviews, EarlyView.
The principle of a reversible clearing strategy via glycerol and tartrazine solution (GTS) for robust whole‐slide label‐free phase imaging of thick tissue slices via high‐throughput Fourier ptychographic microscopy (FPM) and lensless digital holographic microscopy (LDHM). ABSTRACT Thick biological specimens impose strong scattering and attenuation that

HoloSpec: Dispersion‐Based 4D Computational Holographic Hyperspectral Imaging

Laser &Photonics Reviews, EarlyView.
HoloSpec, a compact dispersion‐based computational holographic system, achieves four‐dimensional imaging by retrieving 3D spatial structure and high‐resolution spectra from only two monochromatic snapshots. Using a single prism and a monochrome sensor, it resolves 430 spectral channels with 3 nm experimental resolution and 30 μm$\mathrm{\mu}\mathrm{m}$

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

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

Laser &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 ...
