Geometric phase diffractive waveplate singularity arrays
, 2019 A general geometric phase singularity array structure is presented and discussed. For any two-dimensional point lattice, a singularity array is defined as a summation of helical phase singularities with alternating handedness. The phase angle is the slow-

Singularity in entanglement negativity across finite-temperature phase transitions [PDF]
Physical review B, 2018 Phase transitions at a finite (i.e. non-zero) temperature are typically dominated by classical correlations, in contrast to zero temperature transitions where quantum mechanics plays an essential role.

, 2021 The metal-dielectric stacks-based asymmetric Fabry-Perot (F-P) cavity systems have recently attracted much interest from the scientific community for realizing perfect absorption over the spectral bands from visible to infrared since they possess a ...

Phase singularity detection through phase map interpolation: Theory, advantages and limitations
Comput. Biol. Medicine, 2018 BACKGROUND During a cardiac arrhythmia, reentrant waves rotate around critical points called phase singularities (PS). PS detection is relevant to the quantitative description of the dynamics and to the identification of potential targets for ablation ...

The nonmodular topological phase and phase singularities [PDF]
Physics Letters A, 2011 Generalizing an earlier definition of the noncyclic geometric phase (R.Bhandari, Phys.Lett.A, 157, 221 (1991)), a nonmodular topological phase is defined with reference to a generic time-dependent two-slit interference experiment involving particles with N internal states in which the internal state of both the beams undergoes unitary evolution.

Phase transition through the splitting of self-dual spectral singularity in optical potentials. [PDF]
Optics Letters, 2017 We consider optical media, which feature antilinear symmetries. We show that (i) spectral singularities of such media (if any) are always self-dual, i.e., correspond to coherent perfect absorber lasers; (ii) under the change of a system parameter, the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

The zonal satellite problem - II: Near-escape flow [PDF]
Serbian Astronomical Journal, 1998 The study of the zonal satellite problem is continued by tackling the situation r→∞. New equations of motion (for which the infinite distance is a singularity) and the corresponding first integrals of energy and angular momentum are set up.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...
