Intensifying translocal precarity: The impact of COVID‐19 on smallholder farmers' commodity production and social reproduction in Cambodia

Area, EarlyView.
Short Abstract Our paper argues that COVID‐19 deepened the translocal precarity of smallholder households, who already had to struggle with volatile commodity production and uncertain labour migration. Through the lens of translocal precarity, it reveals how the pandemic played out within a broader conjuncture of agrarian transformation, defined by ...

Extragalactic filament detection with a layer smoothing method [PDF]

, 2014
Filaments are clearly visible in galaxy distributions, but they are hardly detected by computer algorithms. Most methods of filament detection can be used only with numerical simulations of a large-scale structure.

Reconstructing Magnetotail Reconnection Events Using Data Mining is Feasible and Repeatable

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Recently, Stephens et al. (2023), https://doi.org/10.1029/2022ja031066 utilized a data mining (DM) algorithm, applied to 26 years of magnetospheric magnetometer observations coupled with a flexible formulation of the magnetospheric magnetic field, to reconstruct the global configuration of the magnetotail when the Magnetospheric MultiScale ...

Automatic Adaptive and Targeted Localized Refinement in Transient Structural Dynamic Simulations Using the Multiresolution Finite Wavelet Domain Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 1, 15 January 2026.
ABSTRACT The multiresolution finite wavelet domain method has been meticulously studied in numerous wave propagation simulations, showing excellent convergence properties and very fast computing times. The multiresolution procedure always starts with the coarse solution, and then finer solutions can be superimposed on the coarse solution until ...

Time-control system for communication between data-collection and orbiting [PDF]

, 1974
Platform design includes timers which limit data transmission to times when satellites are within radio communication range. As result of reduced power requirement, data-collection platforms now can be equipped with significantly lighter battery ...

Computing the set of Epsilon-efficient solutions in multiobjective space mission design [PDF]

, 2011
In this work, we consider multiobjective space mission design problems. We will start from the need, from a practical point of view, to consider in addition to the (Pareto) optimal solutions also nearly optimal ones.

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

Precipitation Dominates Forest Net Primary Productivity Variations With Distinct Regional Differences in Yunnan Province, China

Ecology and Evolution, Volume 16, Issue 1, January 2026.
We first classified the forests in Yunnan Province into stable forest and change forest regions, and then further divided the province into five sub‐regions based on topography and climate. Based on this classification, we systematically analyzed the spatiotemporal variation of forest net primary productivity (NPP) across these regions.

Nonlinear Analysis of a Two-Parachute System Undergoing Pendulum Motion [PDF]

Motion resembling that of a pendulum undergoing large-amplitude limit cycle oscillation was observed during a series of flight tests of an unoccupied Orion Capsule Parachute Assembly System (CPAS) comprised of two parachutes and a capsule payload.

Integrating climate data and river modeling to reveal Chinook salmon habitat conditions in subarctic river basins

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Climatic extremes can impact the productivity of aquatic species, affecting ecosystems and fishery‐dependent communities. Advances in climate products, such as gridded datasets and downscaled projections, may be useful for quantifying freshwater habitat conditions and predicting climate change effects on fish.
