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 .

Ganglionated plexi stimulation induces pulmonary vein triggers and promotes atrial arrhythmogenecity: In silico modeling study. [PDF]

PLoS ONE, 2017
BACKGROUND:The role of the autonomic nervous system (ANS) on atrial fibrillation (AF) is difficult to demonstrate in the intact human left atrium (LA) due to technical limitations of the current electrophysiological mapping technique.

Quasi-ordinary power series and their zeta functions [PDF]

, 2003
The main objective of this paper is to prove the monodromy conjecture for the local Igusa zeta function of a quasi-ordinary polynomial of arbitrary dimension defined over a number field.

Terminal Singularities, Milnor Numbers, and Matter in F-theory [PDF]

, 2016
We initiate a systematic investigation of F-theory on elliptic fibrations with singularities which cannot be resolved without breaking the Calabi-Yau condition, corresponding to $\mathbb Q$-factorial terminal singularities.

Backreacting D-brane instantons on branes at singularities

Journal of High Energy Physics, 2017
Non-perturbative D-brane instanton effects in 4d N = 1 $$ \mathcal{N}=1 $$ string compactifications can be geometrized in terms of a backreacted generalized geometry. We extend earlier results to setups in which the D-brane instanton is charged under the

Identifying access barriers faced by rural and dispersed communities to better address their needs: implications and lessons learned for rural proofing for health in the Americas and beyond

Rural and Remote Health, 2023
Introduction: Universal access to health services and universal health coverage are needed to achieve good health for all, yet rural communities face a variety of access barriers.

Robust Damage Detection and Localization Under Complex Environmental Conditions Using Singular Value Decomposition-based Feature Extraction and One-dimensional Convolutional Neural Network

Chinese Journal of Mechanical Engineering, 2023
AbstractUltrasonic guided wave is an attractive monitoring technique for large-scale structures but is vulnerable to changes in environmental and operational conditions (EOC), which are inevitable in the normal inspection of civil and mechanical structures. This paper thus presents a robust guided wave-based method for damage detection and localization

Robust Approach for Rotor Mapping in Cardiac Tissue

, 2019
The motion of and interaction between phase singularities that anchor spiral waves captures many qualitative and, in some cases, quantitative features of complex dynamics in excitable systems.

Deformations of log canonical and $F$-pure singularities [PDF]

, 2018
We introduce a lifting property for local cohomology, which leads to a unified treatment of the dualizing complex for flat morphisms with semi-log-canonical, Du Bois or F-pure fibers.
