Long‐Range Time‐Correlated Single‐Photon Counting Lidar 3D‐Reconstruction From a Moving Ground Vehicle

Journal of Field Robotics, Volume 43, Issue 2, Page 1178-1192, March 2026.
ABSTRACT Time‐correlated single‐photon counting (TCSPC) lidar enables high‐resolution 3D imaging at kilometer range. While previous works have covered long range TCSPC 3D imaging from either stationary or airborne platforms, this is, to the best of our knowledge, the first attempt that use a moving ground vehicle. Fusing measurements taken at different

Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery

Wind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio

Potential Impacts of Climate Interventions on Marine Ecosystems

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Rising global temperatures pose significant risks to marine ecosystems, biodiversity, and fisheries. Recent comprehensive assessments suggest that large‐scale mitigation efforts to limit warming are falling short, and all feasible future climate projections, including those that represent optimistic emissions reductions, exceed the Paris ...

Investigating Remote Warfare as the Radical Undoing of Life: The Compounding Civilian Harm Effects of US‐Led Coalition Bombings in Iraq

Antipode, Volume 58, Issue 2, 2026.
Abstract The increased reliance on remote warfare by US‐led military coalitions presents us with questions of “what war is” and “how to know about war” in the 21st century. In this article we substantiate calls for an embodied epistemology of war by introducing a transdisciplinary research agenda to investigate the temporal and spatial civilian harm ...

Frontex and the University: Positivist Dissonance and the Institutionalisation of Border Violence through Research

Antipode, Volume 58, Issue 2, 2026.
Abstract The paper examines the existing relationships between universities and Frontex, investigating and problematising the intersection between the higher education sector and the violence of the European border regime. We introduce the concept of positivist dissonance to conceptualise these relationships within the wider “industrial‐military ...

Efficient Gradient‐Enhanced Bayesian Optimizer with Comparisons to Conjugate‐Gradient and Quasi‐Newton Optimizers for Unconstrained Local Optimization

International Journal for Numerical Methods in Engineering, Volume 127, Issue 4, 28 February 2026.
ABSTRACT The probabilistic surrogates used by Bayesian optimizers make them popular methods when function evaluations are noisy or expensive to evaluate. While Bayesian optimizers are traditionally used for global optimization, their benefits are also valuable for local optimization.

The Impact of OCO‐2 Seasonally Dependent Sampling on Carbon Flux Estimation in the Northern Tropical Africa

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The large annual carbon source over northern tropical Africa (NTA), inferred from satellite CO2, remains highly debated. Using observing system simulation experiments with Orbiting Carbon Observatory‐2 (OCO‐2) sampling, we show that seasonally dependent sampling can lead to overestimated annual fluxes.
