Extending the ICESAT-2 ATLAS Lidar Capabilities to Other Planets Within Our Solar System
PhotonicsThe ATLAS lidar on NASA’s Earth-orbiting ICESat-2 satellite has operated continuously since its launch in September 2018, with no sign of degradation. Compared to previous international single-beam spaceborne lidars, which operated at a few tens of Hz ...

Advanced Materials, EarlyView.ABSTRACT Biohybrid microswimmers, which integrate the unique mobility and taxis of living cells with the versatility of synthetic cargo, offer exciting opportunities for targeted delivery. However, current biohybrids lack autonomous decision‐making capabilities due to the absence of communication between living and synthetic components. Here, we report

Multibeam Laser Altimeter for Planetary Topographic Mapping [PDF]
Laser altimetry provides an active, high-resolution, high-accuracy method for measurement of planetary and asteroid surface topography. The basis of the measurement is the timing of the roundtrip propagation of short-duration pulses of laser radiation ...

Development of Laterally Graded X‐Ray Multilayer Optics
Advanced Materials Technologies, EarlyView.This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Decreasing Computing Time with Symplectic Correctors in Adaptive Timestepping Routines
, 2010 It has previously been shown that varying the numerical timestep during a symplectic orbital integration leads to a random walk in energy and angular momentum, destroying the phase space-conserving property of symplectic integrators.

Advanced Materials Technologies, EarlyView.This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.
