Phase Multiplexed Optical Computing: Reconfiguring a Multi‐Task Diffractive Optical Processor Using Illumination Phase Diversity

open access: yesLaser &Photonics Reviews, EarlyView.
A monochrome multi‐task diffractive optical network architecture is designed to leverage illumination‐phase multiplexing to dynamically reconfigure its output function and accurately implement a large set of complex‐valued linear transformations between an input and an output aperture.

Activation and Detection of Forbidden Low‐Frequency Raman Modes in MoS2 by Near‐Field Gradient Illumination

open access: yesLaser &Photonics Reviews, EarlyView.
Low‐frequency Raman‐forbidden interlayer phonons in 2D materials are typically hidden by selection rules. Here, we demonstrate that plasmonic near‐field gradients can activate and detect these forbidden low‐frequency modes in a few‐layer MoS2 sample, unveiling a gradient‐driven mechanism for revealing hidden interlayer vibrations and breaking symmetry.

Calibration‐Free Single‐Frame Super‐Resolution Fluorescence Microscopy

open access: yesLaser &Photonics Reviews, EarlyView.
A deep learning framework reconstructs super‐resolved fluorescence images from a single dense camera frame, without any prior calibration or knowledge of the microscope. Trained solely on synthetic data, it generalizes across imaging setups and conditions.

On Order Restricted Inference in Multi‐Step Stage Life Testing for a General Family of Distributions

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Recently, k$$ k $$‐step stage life testing (SLT) has been proposed by Laumen and Cramer (2021) as a natural extension of progressive censoring with fixed censoring times (PC‐FCT) as well as of simple step‐stress accelerated life testing (SSALT).

Trends in Ocean S‐Isotopes May Be Influenced by Major LIP Events

open access: yesGeophysical Monograph Series, Page 341-376., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Monitoring shallow geothermal aquifers with active‐source distributed acoustic sensing: A prognostic feasibility study on the University of Leeds Geothermal Campus

open access: yesNear Surface Geophysics, EarlyView.
Abstract The United Kingdom's shallow aquifers offer significant but underdeveloped geothermal energy resource. Seismic methods can help address this by improving the understanding of aquifer heterogeneity and potentially allowing long‐term monitoring of thermal plumes.
