Farmed Escapees Threaten MHC Diversity in Wild Atlantic Salmon

Evolutionary Applications, Volume 19, Issue 6, June 2026.
ABSTRACT Wild Atlantic salmon populations in Norway and elsewhere are experiencing long‐term declines driven by reduced marine survival, climate change, impacts from aquaculture, introduction of alien species, and environmental degradation. Understanding how immune diversity is affected by these declines, and thus the ability of Atlantic salmon to ...

Optoelectrical Devices for Neural Interfacing: Engineering Integration, Stability, and Multimodal Sensing

Advanced Healthcare Materials, Volume 15, Issue 20, 27 May 2026.
Implantable optoelectrical devices are an effective resource for the modulation and monitoring of neural activity with high spatiotemporal resolution. This review discusses current challenges faced by these devices and outlines future perspectives for the development of next‐generation neural interfaces targeting chronic, multisite, and multimodal ...

Advancing Photonic Inverse Design with Interpretable Machine Learning

Advanced Photonics Research, Volume 7, Issue 5, May 2026.
The work applies the interpretable machine learning technique called LIME (local interpretable model‐agnostic explanations) to the inverse design of photonic chips, revealing hidden optimization patterns and guiding better starting designs. Using insights from LIME improves performance of two‐mode multiplexers, showing interpretable methods can ...

Reprogrammable All‐Photonic Molecular Logic With Ln3+ Luminescent Hybrids in Solid State

Laser &Photonics Reviews, Volume 20, Issue 9, 6 May 2026.
Mario P. de‐Saralegui et al. report an Eu3⁺/Tb3⁺‐doped organic–inorganic hybrid material that enables multiple reprogrammable logic operations using only physical stimuli. Additionally, this solid‐state, all‐photonic platform represents the first example in the literature performing reversible Feynman logic operations, marking a major step toward ...

Modelling of NOLM demultiplexers operating with soliton control pulse

, 1999
Optical soliton pulse may be used as a control signal in nonlinear optical loop mirror (NOLM) demultiplexers in order to reduce timing-jitter noise. A mathematical model for calculating the width and profile of the soliton switching window and maximising

Arrayed waveguide grating demultiplexers: a new efficient numerical analysis approach

, 1999
This paper addresses the topic of the simulation analysis of arrayed waveguide grating demultiplexers. These are very important devices used for WDM communications and, being quite a complex structure, they need accurate and efficient simulation tools to

Design of wavelength multiplexers/demultiplexers for WDM optical networks [PDF]

, 1995
Wavelength multi/demultiplexers are essential components in wavelength routed networks. The design requirements for a free-space diffraction grating with subnanometer channel spacing are presented. The analytic conditions for stationarity of second order
