Digital Disease Ecologies: Encounter, Datafication and the Digital Geographies of One Health

Transactions of the Institute of British Geographers, EarlyView.
Short Abstract Through the case of Snake Awareness Rescue Protection App (SARPA), a digital snake translocation and snakebite prevention mobile phone application in Kerala, India, this paper extends recent geographical ‘digital ecologies’ scholarship's concern for the digitisation of more‐than‐human worlds to digital health technology and disease ...

A Jacobian‐Free Newton‐Krylov Method for Cell‐Centred Finite Volume Solid Mechanics

International Journal for Numerical Methods in Engineering, Volume 127, Issue 3, 15 February 2026.
ABSTRACT This study proposes a Jacobian‐free Newton‐Krylov approach for finite‐volume solid mechanics. Traditional Newton‐based approaches require explicit Jacobian matrix formation and storage, which can be computationally expensive and memory‐intensive.

Reducing low‐dose exposure in helical TomoTherapy for locally advanced left‐sided breast cancer with a deformable image registration–based dose‐mimicking workflow

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Helical TomoTherapy provides highly conformal dose distributions for breast irradiation but is limited by extensive low‐dose spillage (“low‐dose bath”), contributing to increased integral dose and potential long‐term toxicities. Complete blocks can suppress low‐dose spread, but at the cost of prolonged treatment times on legacy ...

Reduction of degrees of Freedom in three-dimensional ANCF beam of 24-DOF beam element by component mode synthesis

Nihon Kikai Gakkai ronbunshu, 2014
This paper describes how to reduce degrees of freedom for the absolute nodal coordinate formulation (ANCF) of three-dimensional beam made up of 24 degrees of freedom beam elements by applying the component mode synthesis. The stiffness matrix of the ANCF

Dynamic analysis of rotating shafts using the absolute nodal coordinate formulation

Journal of Sound and Vibration, 2019
Abstract A finite-element based absolute nodal coordinate formulation (ANCF) is applied to dynamic analysis of high-speed rotating shafts. To this end, a four-node higher-order ANCF beam element with third-order derivatives in the axial and cross-section directions is studied.

Commissioning of a Monte Carlo‐based scanning proton beam for breast cancer: Incorporating LETd calculations and variable RBE models

Journal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Using a constant relative biological effectiveness (RBE = 1.1) in proton therapy may underestimate the RBE‐weighted dose in high linear energy transfer (LET) regions at the distal end of the beam, thereby limiting the ability to accurately predict clinical outcomes.
