Numerical Study for Unsteady Waves Generated by Flow over a Permeable Wavy Bed
Fluids, 2021 In this paper, we formulate a numerical model to study unsteady waves generated by fluid flow over a permeable wavy bed. The model is derived from boundary value problems using potential theory.

Fundamental measure theory for the electric double layer: implications for blue-energy harvesting and water desalination [PDF]
, 2015 Capacitive mixing (CAPMIX) and capacitive deionization (CDI) are promising candidates for harvesting clean, renewable energy and for the energy efficient production of potable water, respectively. Both CAPMIX and CDI involve water-immersed porous carbon (

Generating Function Method for Calculating the Potentials of Inhomogeneous Polyhedra
Frontiers in Physics, 2022 We propose a method of constructing analytical, closed-form expressions for electrostatic/Newtonian potentials of non-uniform polyhedral bodies, in which the density distributions are polynomials of coordinates.

On generalizations of some fixed point theorems in semimetric spaces with triangle functions
Frontiers in Applied Mathematics and StatisticsIn the present study, we prove generalizations of Banach, Kannan, Chatterjea, Ćirić-Reich-Rus fixed point theorems, as well as of the fixed point theorem for mapping contracting perimeters of triangles.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.
