HoloSpec: Dispersion‐Based 4D Computational Holographic Hyperspectral Imaging

open access: yesLaser &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$\mathrm{\mu}\mathrm{m}$

Assembling Engagement With Autonomy and Language ‐ A Neuroscientific Case Study With Digital Companions

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT This study addresses the need to understand human engagement with empathic Generative Artificial Intelligence (GenAI) digital companions (DC), as these systems increasingly fulfil social and emotional roles in daily life. Motivated by the rapid adoption of DC technologies and their potential to reshape human–AI relationships, the study applies

Market Interviews in Shared Traumatic Reality: A Trauma‐Informed, Co‐Constructed Framework

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Qualitative market interviews may become trauma‐sensitive when ordinary questions about consumption, work, finance, mobility, identity, professional continuity, or institutional trust intersect with displacement, insecurity, loss, or ongoing threat.

Beyond Reality Avoidance: Unraveling the Paradox of Escapism Through Self‐Monitoring and Autonomy Mechanisms for Consumers' Life Satisfaction

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT This study introduces the Paradox of Escapism, exploring how the act of escaping reality can evolve from a short‐term avoidance strategy to a mechanism for self‐regulation and enhanced life satisfaction. Employing five rigorous, multimethod investigations, including qualitative interviews and sentiment analysis (Study 1), Structural Equation ...

When Connection Feels Empty: Rethinking Consumer Loneliness Through Dual Presence in Digital Marketing

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Digital marketplaces sell connection, yet loneliness persists among their users. Marketing scholarship has largely examined loneliness as a consumer‐level deficit, studying how individuals compensate through consumption. How digital environments themselves structure the conditions under which loneliness is experienced has received less ...

Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

Self‐calibrated B1+ and B0 Field Inhomogeneities Estimation (SAFE) in 3D Magnetic Resonance Fingerprinting

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop SAFE, a self‐calibrated framework to estimate B1+ and B0 field inhomogeneities directly from conventional magnetic resonance fingerprinting (MRF) acquisitions and improve its quantification accuracy. Methods SAFE utilized a two‐step approach. First, two physics‐informed image markers are extracted from the MRF data to create

Placental Blood‐Flow Velocity Quantification From Diffusion MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Altered placental capillary blood flow is closely linked to obstetric complications, yet quantifying capillary‐scale blood velocity remains challenging with existing imaging methods. This is partially because capillary networks form disordered microvascular beds at the voxel scale, rather than coherent, directional vessels.
