Stance and Gait Analysis of Apollo Astronauts on the Moon

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aim As humans return to the Moon, safe efficient ambulation and fall prevention on the lunar surface are key concerns. The analysis of gait from archived Apollo mission video footage is now possible with pose estimation video analysis software.

Generating Dark Matter Subhalo Populations Using Normalizing Flows

The Open Journal of Astrophysics
Strong gravitational lensing is a powerful tool for probing the nature of dark matter, as lensing signals are sensitive to the dark matter substructure within the lensing galaxy.

Mass discrepancy in galaxy clusters as a result of the offset between dark matter and baryon distributions

, 2010
Recent studies of lensing clusters reveal that it might be fairly common for a galaxy cluster that the X-ray center has an obvious offset from its gravitational center which is measured by strong lensing. We argue that if these offsets exist, then X-rays

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

Nano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Lectures on Gravitational Lensing [PDF]

, 1996
These lectures give an introduction to Gravitational Lensing. We discuss lensing by point masses, lensing by galaxies, and lensing by clusters and larger-scale structures in the Universe. The relevant theory is developed and applications to astrophysical

Queer in Science, Technology, Engineering, and Mathematics: Following the Intersections of Queerness, Transness and Science Identities

Science Education, EarlyView.
ABSTRACT This multiple case study explores the intersections of queerness/transness and science education through a combined framework of queer theory, intersectionality, the construct of figured worlds and science identity. The study uses a life‐history approach to characterize the trajectories of three purposefully selected queer individuals who are ...

A Reidentification of Six Candidate Gravitationally Lensed Gamma-Ray Bursts

The Astrophysical Journal
The gravitational lensing effect of gamma-ray bursts (GRBs) holds significant and diverse applications in the field of astronomy. Nevertheless, the identification of millilensing events in GRBs presents substantial challenges.

When Darwin Met Einstein: Gravitational Lens Inversion with Genetic Algorithms

, 2005
Gravitational lensing can magnify a distant source, revealing structural detail which is normally unresolvable. Recovering this detail through an inversion of the influence of gravitational lensing, however, requires optimisation of not only lens ...

The Measurement‐Impact Gap: A Bibliometric Diagnosis of Development Finance Institutions and SDG Research

Sustainable Development, EarlyView.
ABSTRACT The role of Development Finance Institutions (DFIs) in achieving the Sustainable Development Goals (SDGs) is a topic of growing scholarly importance. While existing literature has mapped the thematic scope of this field, a critical diagnosis of its intellectual structure and inherent biases is missing.
