Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, Volume 73, Issue 5, Page 1750-1798, August 2026.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...

Modeling Potential Environmental Impacts of Science Activity in Antarctica

Transactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT We use GPS data collected on science expeditions in Antarctica to estimate hiking functions for the speed at which humans traverse terrain differentiated by slope and by ground cover (moraines and rock). We use the estimated hiking functions to build weighted directed graphs as a representation of specific environments in Antarctica.

Optical Phased Arrays on Photonic Integrated Circuit Platforms: Challenges, Opportunities, and Future Applications

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Integrated optical phased arrays are emerging as scalable engines for solid‐state beam steering and programmable wavefront control. This Review maps the field from beam‐steering principles and core building blocks to material platforms, system‐level bottlenecks, and application frontiers, highlighting how heterogeneous integration, aperiodic ...

A Scalable Large‐Area Fabrication Strategy for Transparent Polymeric Encapsulated Metagratings

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
Transparent encapsulated polymeric guided‐mode resonant metagratings are fabricated by thermal nanoimprint lithography and experimentally validated through structural and optical characterization. The scalable fabrication strategy enables selective RGB reflection and provides a practical route toward large‐area augmented reality and wavelength ...

Global Cooling Driving the Increase in Erosion Rates Across the Himalaya Since the Quaternary

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Late Cenozoic global cooling is well documented, yet its impact on erosion rates in active mountain belts, particularly after the onset of Quaternary glaciation, remain contentious. This ambiguity partially stems from the potential methodological biases in erosion rate quantification, particularly in the Himalaya, where recent studies report ...
