The spread of non‐native species

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1197-1234, June 2026.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Sub-collision hyperfine structure of nonlinear-optical resonance with field scanning

open access: yes, 2004
Some experimental evidences for methane are produced that the simple transition from frequency scanning of nonlinear-optical resonances to magnetic one may be accompanied with transition from sub-Doppler collisionally broadened structure to sub-collision

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Evaluation of Modeling Assumptions for Predicting Structural Damage and Train Derailment Under Earthquake Loading

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.
ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Discrete elements method to model ballast behaviour under railway turnouts

open access: yesCogent Engineering
Ballast behaviour has a profound impact on global track performance and durability, particularly for turnouts where dynamic forces are substantial. As ballast is a discontinuous material, this paper proposes the application of a Discrete Element Method ...

Exploring Lived Experiences of Men Diagnosed With Prostate Cancer in Oman: A Qualitative Study

open access: yesHealth Expectations, Volume 29, Issue 3, June 2026.
ABSTRACT Background Life after prostate cancer treatment may extend across decades; however, qualitative evidence describing how men in Oman navigate treatment sequelae, disclosure, family involvement, and religious coping remains limited. This study explored the lived experiences of Omani men who had completed primary therapy for prostate cancer ...

A Critical Response to the UK's ‘Sullivan Review’ Into Sex and Gender in Research and Data

open access: yesTransactions of the Institute of British Geographers, Volume 51, Issue 2, June 2026.
ABSTRACT This intervention argues that the UK Government‐commissioned independent review of data, statistics and research on sex and gender (the ‘Sullivan Review’) implicitly promotes the erasure of trans and gender diverse people from research and data collection protocols and carries worrying implications for the inclusion of trans people within UK ...

Prediction of Lifespan of Railway Ballast Aggregate According to Mechanical Properties of it

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2017
As the railway lifespan is the main criterion for selection of the aggregate for ballast and for planning the maintenance of the railroad, it is important to define the relationship between the particle load resistant characteristics and a lifetime of ...

Ultra-heavy vertical lift system: The Heli-Stat [PDF]

open access: yes, 1975
A hybrid VTOL airship which is combined with helicopters is evaluated. The static lift of the airship supports approximately the full empty weight of the entire assembly.
