Communicating mathematics through images: A multimodal study of Year One students’ meaning-making when working with mathematics textbooks

open access: yesLUMAT, 2021
This article focuses on how Swedish Year One students (age 7–8) make meaning when working with images in mathematics textbooks. Images include textbook images, but also students’ self-drawn images used as support for calculation.

Log file‐based quality assurance method for respiratory gating system

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

Point Spread Function Estimation of Defocus [PDF]

open access: yesarXiv, 2022
This Point spread function (PSF) plays a crucial role in many computational imaging applications, such as shape from focus/defocus, depth estimation, and fluorescence microscopy. However, the mathematical model of the defocus process is still unclear. In this work, we develop an alternative method to estimate the precise mathematical model of the point

Shimura varieties in the Torelli locus via Galois coverings [PDF]

open access: yes, 2014
Given a family of Galois coverings of the projective line we give a simple sufficient condition ensuring that the closure of the image of the family via the period mapping is a special (or Shimura) subvariety in A_g. By a computer program we get the list

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Mucus Physically Restricts Influenza A Viral Particle Access to the Epithelium

open access: yesAdvanced Biology, EarlyView.
The infectious potential of respiratory viruses depends on their ability to navigate through a layer of mucus that serves as a protective barrier in the lung. It is demonstrated that influenza A virus penetration through mucus is significantly limited by the gel's internal microstructure and, to a lesser extent, by adhesive binding to mucin glycans ...
