Passive thermal compensation lens

Patent published on the 2026-10-15 in US under Ref US20260319144 by SNAP INC [US] (Crosby David Nicholas [gb], Jacoby Thomas Norman Llyn [gb], Woods David Mark [gb])

Abstract: [0000] A passively athermalized optical assembly comprises an expanding lens having an optical power that becomes more positive when a temperature of the optical assembly increases from a first temperature to a second temperature. The more positive optical power of the expanding lens complements changes in other components of the optical assembly such that an outgoing light bundle maintains a propagation trajectory when the temperature of the optical assembly changes from the first temperature t[...]


Our summary: A passive thermal compensation lens adjusts its optical power positively with temperature increases. This change maintains the outgoing light bundle s trajectory. The design ensures stability in optical performance across temperature variations.

a minimal model for sperm dynamics

Published on 2026-10-09 by Adrian Pacheco-Pozo, Arturo Matamoros Volante, Pilar Ameijeiras, Mariano G Buffone and Diego Krapf @IOP SCIENCE

Abstract: Active biological microswimmers typically combine persistent self-propulsion with cyclic motion generated by flagellar or ciliary beating. However, standard active Brownian motion (ABM) does not explicitly account for these intrinsic oscillations. This limitation is particularly relevant for sperm cells, whose transport depends not only on directional persistence and stochastic reorientation but also on periodic head motion. Here we introduce oscillatory active Brownian motion (OABM), a minimal [...]


Our summary: This study introduces oscillatory active Brownian motion (OABM) to model sperm dynamics, incorporating periodic head motion. OABM extends standard active Brownian motion by adding a periodic angular drive to swimmer orientation. The model successfully predicts sperm motility patterns and links flagellar kinematics to transport dynamics.

Magnetic-field-induced nondipole effect in strong field frustrated double ionization

Published on 2026-09-30 by Linna Zhang, Mingzheng Wei, Luling Jin, Huipeng Kang and Xiaojun Liu @IOP SCIENCE

Abstract: Strong field atomic frustrated double ionization (FDI) represents a novel approach for ultrafast preparation and control of highly excited ions. A comprehensive understanding of its mechanism is of fundamental significance. However, current interpretations are restricted to the dipole approximation. Here, the nondipole effect in FDI of Ar is investigated using a classical ensemble model, in which the magnetic component of the laser field is fully accounted for. We show that the magnetic field in[...]


Our summary: This study investigates the nondipole effect in strong field frustrated double ionization (FDI) of Ar. It reveals that the magnetic field enhances the momentum of photoelectrons along the laser direction, influenced by laser intensity. The findings provide insights into manipulating momentum transfer and probing ultrafast magnetic fields.
