High order second derivative diagonally implicit multistage integration methods for ODEs
Mathematical Modelling and Analysis, 2023 Construction of second derivative diagonally implicit multistage integration methods (SDIMSIMs) as a subclass of second derivative general linear methods with Runge–Kutta stability property requires to generate the corresponding conditions depending of ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An international Delphi panel of experts developed consensus statements to delineate the circumstances where the risks of dexamethasone as an antiemetic do and do not outweigh its benefits. Procedure Experts in supportive care of pediatric patients were invited to participate.

From efficient symplectic exponentiation of matrices to symplectic integration of high-dimensional Hamiltonian systems with slowly varying quadratic stiff potentials [PDF]
, 2011 We present a multiscale integrator for Hamiltonian systems with slowly varying quadratic stiff potentials that uses coarse timesteps (analogous to what the impulse method uses for constant quadratic stiff potentials).

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Stiff Oscillatory Systems, Delta Jumps and White Noise [PDF]
Foundations of Computational Mathematics, 2001 Consider the scalar ordinary differential equation (ODE) \[ dz_{N}/dt=f(z_{N})+H_{n}(t),\;0\leq t\leq \pi,\quad z_{N}(0)=z_{0},\tag{*} \] (\(f\) of class \(C^{\infty }\) global Lipschitz) with the oscillatory forcing term \(H_{N}(t)=\sum_{j=0}^{N}u_{j}(t)\), \(N\gg 1\), where \(u_{j}(t)\) are harmonic oscillator solutions to \[ d^{2}u_{j}/dt^{2}+j^{2 ...

Recycling neutron stars to ultra short periods: a statistical analysis of their evolution in the mu-P plane [PDF]
, 1999 We investigate the statistical evolution of magnetic neutron stars, recycled in binary systems, simulating synthetic populations. To bracket uncertainties, we consider a soft (FP) and a stiff (PS) equation of state (EoS) for nuclear matter and explore ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.
