Far‐field bioluminescent immune cell–mediated photodynamic therapy is limited by photon flux

Photochemistry and Photobiology, EarlyView.
Bioluminescent immune cell‐mediated photodynamic therapy uses tumor‐homing, luciferase‐expressing immune cells as internal light sources to activate photosensitizers in deep‐seated and/or micrometastatic tumors. Using both experiments and computational simulations, we find that this approach delivers insufficient far‐field energy to tumor cells to ...

Validated computational modeling to evaluate spatial inactivation of airborne pathogens by Far‐UVC irradiation

Photochemistry and Photobiology, EarlyView.
Inactivation trajectories of virus‐laden particles in rooms with different ventilation rates as they move under the light of a variety of Far‐UVC devices. Abstract Recent experimental studies have indicated the potential for ultraviolet C irradiation at 222 nm (Far‐UVC) to be used in occupied rooms to safely reduce exposure to airborne pathogens.

Performance Analysis of Coded $M$-ary Orthogonal Signaling Using Errors-and Erasures Decoding Over Frequency-Selective Fading Channels

, 2001
The performance of $M$-ary orthogonal signaling schemes employing Reed–Solomon (RS) codes and redundant residue number system (RRNS) codes is investigated over frequency-selective Rayleigh fading channels.

Hybrid deep learning for robust spectrum sensing over AWGN and fading channels

EURASIP Journal on Advances in Signal Processing
Accurate and reliable spectrum sensing (SS) is crucial for optimal spectrum usage in cognitive radio (CR) networks under challenging low signal-to-noise ratio (SNR) and fading channel conditions. The Bi-CLNetwork, a hybrid deep learning (DL) architecture,

An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...

Effects of Mineralogical Inhomogeneity on Aggregate Dust Optical Properties and Lidar Observables

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Dust aerosols comprise irregular grains and aggregates with various mineralogical mixtures. However, most optical models use effective refractive indices to represent particles. This study develops an inhomogeneous aggregate model assigning mineral‐dependent refractive indices to constituent elements and representing global mineral volume ...

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, Volume 36, Issue 80, 5 October 2026.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.

KALMAN FILTERING FOR SPACE-TIME CODED TRANSMISSIONS OVER FREQUENCY-SELECTIVE RAYLEIGH FADING CHANNELS

Electrica, 2005
The problem of multichannel estimation for space-time coded transmissions over frequency-selective Rayleigh fading channels is addressed. Under  fast fading conditions, receivers employing Kalman filtering and moderate complexity equalization schemes are
