Advances in the Design and Functionality of a Compact Multi‐Reflecting Time‐of‐Flight Mass Spectrometer

Rapid Communications in Mass Spectrometry, Volume 40, Issue 22, 30 November 2026.
ABSTRACT Rationale High‐resolution mass spectrometry is routinely used for the analysis of complex samples in pharmaceutical, environmental, and omics related studies. Such applications demand instrumentation to be capable of combining sub‐ppm mass accuracy, high resolving power, rapid full m/z range acquisition over a wide dynamic range.

Widespread On‐Fault Geologic Evidence for Variable Mode Coseismic Slip to the Trench in Cascadia

AGU Advances, Volume 7, Issue 8, November 2026.
Abstract Investigating the geologic record of near‐trench coseismic strain release is critical for estimating the slip distribution and tsunamigenic potential of future large subduction zone earthquakes. However, the style and extent of upper plate coseismic deformation offshore in subduction zones is poorly constrained.

Behavioural Diversity of Fishes: Concepts, Drivers and Its Role in Conservation and Management

Fish and Fisheries, Volume 27, Issue 6, Page 1245-1268, November 2026.
ABSTRACT Human activity has altered nearly all ecosystems on Earth, contributing to substantial biodiversity loss across taxonomic, genetic and functional dimensions, from the intraspecific to the ecosystem scale. Yet some components of biodiversity remain hidden or underappreciated, including behavioural diversity.

An Effective Strategy of Object Instance Segmentation in Sonar Images

IET Signal Processing
Instance segmentation is a task that involves pixel-level classification and segmentation of each object instance in images. Various CNN-based methods have achieved promising results in natural image instance segmentation. However, the noise interference,

Quantifying Deep Ocean Methane Along the Central Chilean Margin

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Cold seeps are dynamic seafloor environments that provide conduits for methane (CH4) to be transferred from marine sediments to the global ocean and, in shallow settings, the atmosphere. These seeps are ubiquitous along continental margins yet their spatial extent and impact on the marine carbon cycle are poorly constrained.
