Navigation techniques for large-scale astronomical exploration

, 2006
Navigating effectively in virtual environments at human scales is a difficult problem. However, it is even more difficult to navigate in large-scale virtual environments such as those simulating the physical Universe; the huge spatial range of ...

Time scale evaluation and the quantification of obliquity forcing [PDF]

, 2019
The geologic time scale serves as an essential instrument for reconstructing Earth history. Astrochronology, linking regular sedimentary alternations to theoretical quasi-periodic astronomical rhythms, often provides the highest resolution age models for

Measuring the Hall Effect in Hysteretic Materials

Advanced Materials, EarlyView.
The authors highlight common pitfalls in measuring the Hall effect: in hysteretic magnets, improper data processing can create signals that look exotic but are not real. This Perspective explains the origin of these artifacts and presents practical measurement strategies that help researchers identify reliable Hall responses in complex magnetic ...

Improving the Neogene Tuned Time Scale

, 2013
Orbital tuning and understanding climate response to astronomical forcing in the Miocene requires detailed knowledge of the accuracy of the astronomical solution used to compute insolation and orbital target curves for paleoclimatic studies.

Revitalizing Traditional Astronomical Instruments: Developing a Local Dial Model for Accurate Prayer Time Determination

Al-Hilal
This study addresses the limitations of contemporary prayer time instruments, which often require complex calculations, electricity, internet connectivity, or direct exposure to sunlight, by developing a practical, local dial–based tool for community use.

Weak In‐Plane Ferromagnetism and Electronic Nematicity in the Distorted Triple‐Q Magnetic Phase of Co1/3TaS2

Advanced Materials, EarlyView.
Co1/3TaS2${\rm Co}_{1/3}{\rm TaS}_{2}$ hosts a triple‐Q noncoplanar antiferromagnetic state with coexisting Z3${\rm Z}_3$ electronic nematicity. We report rotational hysteresis observed in both magnetoresistance and magnetic torque, revealing strongly pinned in‐plane weak ferromagnetic moments in the triple‐Q phase and the magnetism‐driven nature of ...
