Caustic Skeleton & Cosmic Web [PDF]
Journal of Cosmology and Astroparticle Physics, 2018 We present a general formalism for identifying the caustic structure of an evolving mass distribution in an arbitrary dimensional space. For the class of Hamiltonian fluids the identification corresponds to the classification of singularities in ...

Corrosive Esophageal Injury due to a Commercial Vinegar Beverage in an Adolescent [PDF]
Clinical Endoscopy, 2020 Although gastroesophageal damage is commonly induced by accidental drinking of a strong acid or alkali, damage due to the consumption of a vinegar beverage is not well known. We report a case of corrosive esophageal ulcer found in an adolescent consuming

Opto-Electronic Advances, 2021 Self-accelerating beams have the unusual ability to remain diffraction-free while undergo the transverse shift during the free-space propagation. We theoretically identify that the transverse optical field distribution of 2D self-accelerating beam is ...

The Identification of Dark Matter, 2000 Abstract: The late infall of cold dark matter onto an isolated galaxy such as our own produces flows with definite velocity vectors at any physical point in the galactic halo. It also produces caustics which are places where the dark matter density is very large. The outer caustics are topological spheres whereas the inner caustics are rings. The self‐

Centre Symmetry Sets of Families of Plane Curves
Demonstratio Mathematica, 2015 We study centre symmetry sets and equidistants for a I-parameter family of plane curves where, for a special member of the family, there exist two inflexions with parallel tangents.

Journal of Marine Science and Engineering, 2021 Seafloor geoacoustic properties are important in determining sound propagation in the marine environment, which broadly affects sub-sea activities. However, geoacoustic investigation of the deep seafloor, which is required by the recent expansion of deep-

Does the Second Caustic Ring of Dark Matter Cause the Monoceros Ring of Stars ? [PDF]
, 2007 Caustic rings of dark matter were predicted to exist in the plane of the Galaxy at radii $a_n \simeq 40 {\rm kpc}/n$ for $n = 1,2,3 ..$. The recently discovered Monoceros Ring of stars is located near the $n=2$ caustic, prompting us to consider a ...

Properties of Central Caustics in Planetary Microlensing [PDF]
, 2005 To maximize the number of planet detections, current microlensing follow-up observations are focusing on high-magnification events which have a higher chance of being perturbed by central caustics.
