Lipid droplet profiling during neutrophil differentiation by stimulated Raman scattering microscopy

Biotechnology Progress, EarlyView.
Abstract Lipid droplets (LDs) are dynamic organelles that serve as metabolic hubs and emerging regulators of immune cell fate. Although LDs have been implicated in immune regulation, how LD metabolism is remodeled during neutrophil differentiation and how stage‐specific LD dynamics shape mature neutrophil function remain poorly defined.

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

Ultra‐High Frequency Ultrasound Imaging and Quantification of Microvascular Flow in Xenograft Renal Cell Carcinoma in an Avian Chorioallantoic Membrane Model

Journal of Ultrasound in Medicine, EarlyView.
Patient‐derived xenograft (PDX) tumor models initiated in avian chorioallantoic membranes (CAM) are under investigation to evaluate the effectiveness of therapeutic options with the objective of personalizing treatments. CAM PDXs paired with ultra‐high frequency ultrasound (UHFUS) imaging could potentially constitute prospective high throughput assays ...

Statistical mechanics of CDMA multiuser demodulation

, 2001
I investigate the multiuser demodulation problem which arises in code-division multiple-access (CDMA) systems. The relationship between the multiuser demodulation problem and a variant of the Hopfield model is established, based on which the replica ...
