The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Endurance Training in Olympic Winter Sports: A Narrative Review of the Current Literature and Future Research Priorities

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT The Milano‐Cortina 2026 Winter Olympics present an opportunity to synthesize evolving paradigms in endurance training within the broader context of long‐term athlete development. As Olympic winter sports span from endurance‐limited events to disciplines in which aerobic fitness primarily serves as a feeder capacity, a single training model is ...

Direct Observational Evidence of the Mesoscale Gravity Wave Modulations on Low‐Latitude Sporadic E Layer

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Sporadic E (Es) layer plays essential role in ionosphere‐atmosphere coupling. Theoretical simulations show that the atmospheric gravity waves (GWs) in the lower thermosphere are the main modulatory source on Es dynamics at small spatial scales and short periods.
