Scientific Reports, 2022 Irregular spatial distribution of photon transmission through a photochromic crystal photoisomerized by a local optical near-field excitation was previously reported, which manifested complex branching processes via the interplay of material deformation ...

Sharp Focusing of a Hybrid Vector Beam with a Polarization Singularity
Photonics, 2021 The key result of this work is the use of the global characteristics of the polarization singularities of the entire beam as a whole, rather than the analysis of local polarization, Stokes and Poincare–Hopf indices.

Application of singularity theory and logistic regression model for tungsten polymetallic potential mapping [PDF]
Nonlinear Processes in Geophysics, 2013 Geo-anomalies with complex structures in the earth's crust may be defined as preferable hydrothermal ore-forming targets. The separation and explanation of anomaly from geological background have a profound influence on the analysis of geological ...

A Parametric Shape Model Applied to Tracing the Migration of the Objects Near an Asteroid
Earth and Space Science, 2021 In the past decades, space missions to small bodies (Galileo, OSIRIS‐REx, Hayabusa, Hayabusa2, Chang'e 2, Rosetta, etc.) have enriched us greatly with voluminous new knowledge on our solar system.

Comptes Rendus. MathématiqueWe define a Hodge-theoretical refinement of the Lyubeznik numbers for local rings of complex algebraic varieties. We prove that these numbers are independent of the choices made in their definition and that, for the local ring of an isolated singularity,

Beyond the average: Detecting global singular nodes from local features in complex networks [PDF]
EPL (Europhysics Letters), 2009 Deviations from the average can provide valuable insights about the organization of natural systems. The present article extends this important principle to the systematic identification and analysis of singular motifs in complex networks. Six measurements quantifying different and complementary features of the connectivity around each node of a ...

Brown measures of deformed $L^\infty $ -valued circular elements
Forum of Mathematics, SigmaWe consider the Brown measure of $a+\mathfrak {c}$ , where a lies in a commutative tracial von Neumann algebra $\mathcal {B}$ and $\mathfrak {c}$ is a $\mathcal {B}$ -valued circular element.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Therapeutic apheresis (TA) is an established treatment modality for hematologic, neurologic, and immunologic disorders, yet access remains severely limited in sub‐Saharan Africa. Donor apheresis, including platelet apheresis collection from healthy donors, represents an important complementary modality supporting blood product ...

Bouncing singularities and thermal correlators on line defects
Journal of High Energy PhysicsThermal correlators in holographic conformal field theories are known to exhibit singularities in complex time, sometimes referred to as “bouncing singularities”, which are believed to be related to bulk geodesics probing the black hole interior.

On Complex Singularity Analysis for Some Linear Partial Differential Equations in
Abstract and Applied Analysis, 2013 We investigate the existence of local holomorphic solutions Y of linear partial differential equations in three complex variables whose coefficients are holomorphic on some polydisc in outside some singular set .
