Boundary-degenerate elliptic operators and Holder continuity for solutions to variational equations and inequalities [PDF]

, 2011
The Heston stochastic volatility process, which is widely used as an asset price model in mathematical finance, is a paradigm for a degenerate diffusion process where the degeneracy in the diffusion coefficient is proportional to the square root of the ...

Misperception of Body Weight After Childhood Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Misperception of body weight can negatively impact the weight management efforts of childhood cancer survivors (CCSs). Both being overweight or underweight are associated with chronic health conditions commonly observed in CCS; therefore, accurate weight perception is critical for reducing long‐term health risks.

Poincaré analyticity and the complete variational equations [PDF]

, 2011
According to a theorem of Poincare, the solutions to differential equations are analytic functions of (and therefore have Taylor expansions in) the initial conditions and various parameters provided that the right sides of the differential equations are ...

Singularities of a Variational Wave Equation

Journal of Differential Equations, 1996
The authors analyze the formation of singularities in the solutions to variational wave equations of the form \[ u_{tt} - c(u)(c(u)u_x)_x=0. \] Such equations were originally proposed (by the reviewer) as interesting for the study of microscopic effects in nematic liquid crystals, where short time inertial behaviour could be significant.

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).

Applications of the Laplace variational iteration method to fractional heat like equations

Partial Differential Equations in Applied Mathematics, 2023
The importance of differential equations of integer order and fractional order can be seen in many areas of engineering and applied sciences. The present work involves fractional order heat equations that arise in numerous applications of engineering and

LIPSCHITZ REGULARITY FOR INNER-VARIATIONAL EQUATIONS [PDF]

, 2011
We obtain Lipschitz regularity results for a fairly general class of nonlinear first-order PDEs. These equations arise from the inner variation of certain energy integrals.

FBSDEs with time delayed generators:L-P-solutions, differentiability, representation formulas and path regularity [PDF]

, 2011
We extend the work of Delong and Imkeller (2010) [6,7] concerning backward stochastic differential equations with time delayed generators (delay BSDEs). We give moment and a priori estimates in general L-p-spaces and provide sufficient conditions for the

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.
