Spectral Caustics in Attosecond Science

open access: yesEPJ Web of Conferences, 2013
A unique type of singularity common in wave phenomena, known as caustics, links processes observed in many different branches of physics [1]. We investigate the role of caustics in attosecond science and in particular the physical process behind high ...

Architectural caustics – controlling light with geometry [PDF]

open access: yes, 2013
Caustics are captivating light patterns created by materials bundling or diverting light by refraction or reflection. We know caustics as random side effects, appearing, for example, at the bottom of a swimming pool.

Comparison of geometric optics and «aperture» methods for calculation of the electromagnetic radiation caused by charged particles flying by dielectric objects

open access: yesФизика волновых процессов и радиотехнические системы, 2023
Calculation of the electromagnetic field exited by a charged particle flying close to dielectric object is one of the important problems of charged particle radiation theory. In some cases, geometric optics area is preferable for calculations.

Caustics and velocity caustics in the diffuse interstellar medium at high Galactic latitudes [PDF]

open access: yes, 2023
The FIR distribution at high Galactic latitudes, observed with Planck, is filamentary with coherent structures in polarization. These structures are also closely related to HI filaments with coherent velocity structures.

Caustic ingestions

open access: yesMedicina, 2009
Caustic ingestions (alkalis, acids) may cause severe chemical burns and lifelong complications, which worsen life quality. Approximately 80% of caustic ingestions occur in children. They mostly intoxicate because of chemical substances kept insecurely or in inappropriate containers.

Experimental study of the interaction of directional crack and open joint in slit charge blasting

open access: yes工程科学学报, 2021
To explore the interaction between directional crack and open joint in slit charge blasting, a dynamic caustics method and high-speed photography technology were used to carry out the blasting model experiment.

On planar caustics [PDF]

open access: yes, 2016
We study local invariants of planar caustics, that is, invariants of Lagrangian maps from surfaces to R2 whose increments in generic homotopies are determined entirely by diffeomorphism types of local bifurcations of the caustics.

Caustic consideration of long planetary wave packet analysis in the continuously stratified ocean

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2001
The wave packet method, one form of the WKB technique, recently has been employed to investigate the evolution of long planetary wave packets in relation to the complex climate variability in the world oceans.

L-glutamine Supplemented Nutrition Alleviates Damage Caused by Corrosİve Esophagitis in Rats

open access: yesJournal of Behçet Uz Children's Hospital, 2022
Objective: The primary goal in the treatment of corrosive esophagitis (CE) is to control inflammation and scar reactions. L-glutamine (Gln) is beneficial for the integrity of the intestinal mucosal epithelium and is an amino acid that promotes mature ...

The caustics method in the contact problems of anisotropic materials

open access: yesEPJ Web of Conferences, 2010
Regions with high stress gradients represent critical zones of engineering structures such as crack tip or vicinity of the contact zone. The optical method of caustics is one of the few experimental methods which provide applicable results in these ...
