Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Ferromagnetic Cobalt Oxide With Structural Distortion and Oxidation State Changes for Hydrogen Sulfide Gas Detection

open access: yesSmall, EarlyView.
High H2S gas sensitivity was improved by electrochemically engineering Co3O4/CoO heterostructures with oxygen vacancies and aligning nanosized particles via magnetic‐field‐assisted deposition. This alignment enhanced gas diffusion and electron transport, reducing base resistance. The resulting sensor exhibited high selectivity and a strong response (Rg/

Identifying the pre‐Odra river system with hydroacoustic and seismic reflection imagery offshore Rügen Island, southern Baltic Sea

open access: yesBoreas, EarlyView.
Understanding the course and dynamics of ancient river systems, such as the pre‐Odra, provides valuable insights into the post‐glacial evolution of landscapes and riverine processes. The northwest‐trending pre‐Odra was an important drainage system of the European mainland into the Baltic Basin during and after the Scandinavian Ice Sheet retreat ...

The detection of vertical cracks in asphalt using seismic surface wave methods

open access: yes
Assessment of the location and of the extension of cracking in road surfaces is important for determining the potential level of deterioration in the road overall and the infrastructure buried beneath it.

Multichannel Analysis of Surface Waves for Soil Site Characterization

open access: yes, 2019
Shear wave velocity is a fundamental parameter in soil dynamics and geotechnical earthquake engineering. The Multichannel Analysis of Surface Waves (MASW) method is a relatively new non-invasive technique to evaluate the near-surface shear wave velocity profile by utilizing the dispersive properties of surface waves in a heterogeneous medium.

Refined Division of Sleep Stages in the Mouse Based on Distributed Deep Electrodes and Underlying Infra‐Slow Oscillation

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT The mouse sleep is mostly recorded with only epidural electrodes and divided simply into NREM and REM stages. With the help of distributed intracerebral triplet electrodes, we searched for possible new electrophysiological signatures to characterise more specific sleep substages within the timeframe of seconds to tens of minutes.

Acute prefrontal hemodynamic responses to intermittent theta burst stimulation correlate with current depression and episode recurrence: A cross‐sectional study

open access: yesPsychiatry and Clinical Neurosciences, EarlyView.
Background Mounting evidence has indicated that multiple major depressive disorder (MDD) episodes are correlated with brain morphometric changes that confer an increased recurrence risk. Functional abnormalities underlying this recurrent vulnerability remain underexplored.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.
