Abstract and Applied Analysis, 2013 A new modified Runge-Kutta-Nyström method of fourth algebraic order is developed. The new modified RKN method is based on the fitting of the coefficients, due to the nullification not only of the phase lag and of the amplification error, but also of ...

New explicit trigonometrically-fitted fourth-order and fifth-order Runge-Kutta-Nyström methods for periodic initial value problems [PDF]
, 2016 In this work, we derive two new Runge-Kutta-Nyström (RKN) methods for solving periodic second order ordinary differential equations. We constructed these methods based on the RKN method of three-stage fourth-order derived by Garcia and RKN method of four-

Long‐Term Effects of a Web‐Based Exercise Programme for People With Intellectual Disabilities
Journal of Intellectual Disability Research, EarlyView.ABSTRACT Background Physical activity is essential for preventing noncommunicable diseases and improving health parameters. However, individuals with intellectual disabilities often struggle to meet recommended activity levels. Sustainable solutions and long‐term follow‐up are crucial for evaluating intervention efficacy.

Meteoritics &Planetary Science, EarlyView.Abstract Fossil micrometeorites (MMs) recovered from lithified sedimentary rocks, particularly iron‐rich (I‐type) cosmic spherules (CSs) provide valuable insights into past dust‐forming events. Their abundances, when combined with estimates of local sedimentation rates can be used to reconstruct the flux of extraterrestrial dust.

The Journal of Physiology, EarlyView.Abstract figure legend Hypocapnic hyperventilation reduced end‐tidal carbon dioxide partial pressure and middle cerebral artery mean velocity, and impaired oculomotor response by modulating visual fixation and anti‐saccadic control. Hyperventilation itself also impaired anti‐saccadic control.
