Experimental Investigations on Mechanics‐Based Additively Manufactured Stayed Lattice Structures

open access: yesPAMM, Volume 26, Issue 1, March 2026.
ABSTRACT Lattice structures have gained increasing popularity due to their remarkable strength‐to‐weight ratio. With advancements in material extrusion additive manufacturing (MEX), the complex designs of lattice structures have become more accessible and widely applicable. However, their slender components are highly susceptible to elastic buckling at

Facile Bottom‐Up Assembly of Photonic Micropatterns via Surface‐Guided Colloidal Crystallization

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
High‐resolution photonic micropatterns with vivid structural colors are fabricated through bottom‐up assembly, guided by surface‐dependent regioselective heterogeneous nucleation and crystal growth of colloidal particles. Full‐spectrum color tunability is achieved by controlling particle size and interparticle attraction, while in situ color mixing is ...

Constraining Annihilating Dark Matter Using the Multifrequency Radio Flux Profiles of the M33 Galaxy

open access: yesThe Astrophysical Journal
Radio data can give stringent constraints for annihilating dark matter. In general, radio observations can detect very accurate radio flux density with high resolution and different frequencies for nearby galaxies.

Epigenetic Age Estimation for Hawaiian False Killer Whales (Pseudorca crassidens) in the Absence of ‘Known‐Age’ Individuals

open access: yesMolecular Ecology Resources, Volume 26, Issue 2, February 2026.
ABSTRACT Epigenetic aging models hold great promise for enhancing many aspects of wildlife research and management. However, their utility is limited by the need to train models using known‐aged animals, which are rare among wildlife species. We present a novel approach to developing methylation‐based age prediction models that enables us to train ...

A Linearly Polarized Merger Shock Down to 550 MHz: A uGMRT Study of the Merging Cluster A746

open access: yesThe Astrophysical Journal
Radio relics, arc-like polarized sources with highly aligned magnetic fields, are typically found on the outskirts of merging galaxy clusters. The magnetoionic media responsible for the significant coherence observed in radio relics remain poorly ...

Models in Decision‐Making Under Risk and Uncertainty

open access: yesJournal of Economic Surveys, Volume 40, Issue 1, Page 304-320, February 2026.
ABSTRACT This paper systematically compares dominant frameworks for modeling decision‐making under risk and uncertainty, evaluating their theoretical trade‐offs and practical relevance for economic research. We establish key criteria for model selection—including predictive accuracy, descriptive realism, computational tractability, and ecological ...

3D Localization of FRB 20190425A for Its Potential Host Galaxy and Implications

open access: yesThe Astrophysical Journal
Fast radio bursts (FRBs) are high-energy, short-duration phenomena in radio astronomy. Identifying their host galaxies can provide insights into their mysterious origins. In this paper, we introduce a novel approach to identifying potential host galaxies

RAD@home Citizen Science Discovery of Two Spiral Galaxies Where the 30–220 kpc Radio Lobes Are Possibly Shaped by Ram Pressure Stripping

open access: yesGalaxies
We report the RAD@home citizen science discovery of two rare spiral-host radio galaxies (NGC 3898 and WISEA J221656.57-132042434.1 or RAD-“Thumbs up” galaxy), both exhibiting asymmetric radio lobes extending over 30 to 220 kiloparsec scales. We present a
