The Caustics around a Local Density Perturbed Region in Redshift Space and Their Implications to Rich Clusters of Galaxies [PDF]
On the framework of Tolman spacetime model, the caustics around a local perturbed region in redshift is due to the local expansion rate induced by a local density inhomogeneity in real space.

Mixed-mode thermal stress intensity factors (SIFs) are investigated at various temperatures using the method of caustics. First, theoretical caustic patterns are obtained for various types of optical systems in addition to the mode II SIF KII and mode I

Wavefronts, caustic sheets, and caustic surfing in gravitational lensing
Very little attention has been paid to the properties of optical wavefronts and caustic surfaces due to gravitational lensing. Yet the wavefront-based point of view is natural and provides insights into the nature of the caustic surfaces on a gravitationally lensed lightcone.

Natural caustics in backward path tracing [PDF]
In this paper we introduce a natural method for producing both refraction and reflection caustics in backward path tracing (e.g. bouncing around an eye ray in the scene until a light is found). These caustics do not rely on a light location, and as such,

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

New formulas for Maslov's canonical operator in a neighborhood of focal points and caustics in 2D semiclassical asymptotics [PDF]
We suggest a new representation of Maslov’s canonical operator in a neighborhood of caustics using a special class of coordinate systems (eikonal coordinates) on Lagrangian manifolds.
