Effect of different noise reduction techniques and template matching parameters on markerless tumor tracking using dual‐energy imaging

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose To evaluate the impact of various noise reduction algorithms and template matching parameters on the accuracy of markerless tumor tracking (MTT) using dual‐energy (DE) imaging. Methods A Varian TrueBeam linear accelerator was used to acquire a series of alternating 60 and 120 kVp images (over a 180° arc) using fast kV switching, on ...

Complexity of the Basic Reproduction Number (R0)

open access: yesEmerging Infectious Diseases, 2019
The basic reproduction number (R0), also called the basic reproduction ratio or rate or the basic reproductive rate, is an epidemiologic metric used to describe the contagiousness or transmissibility of infectious agents.

A review on theoretical models of suicide [PDF]

open access: yesInternational Journal of Advances in Scientific Research, 2017
Suicide is a major public health issue which is highly complex and multifaceted. Subsequently, after the pioneering work of Durkheim and Freud, researchers and scholars have attempted to explain the biological, social, and psychological nature of suicide.

Theoretical modeling for the stereo mission [PDF]

open access: yesSpace Science Reviews, 2006
We summarize the theory and modeling efforts for the STEREO mission, which will be used to interpret the data of both the remote-sensing (SECCHI, SWAVES) and in-situ instruments (IMPACT, PLASTIC). The modeling includes the coronal plasma, in both open and closed magnetic structures, and the solar wind and its expansion outwards from the Sun, which ...

Game-theoretic models

open access: yes, 2021
Game theory is a tool to model and discover social mechanisms. The aim of this chapter is to show how the tool can be used by engaging the reader's interest in the game-theoretic modelling of social dilemmas. Social dilemmas are situations in which several agents face a decision conflict because of their interdependence.

Theoretical solar models [PDF]

open access: yesSymposium - International Astronomical Union, 1997
In the last two decades the large amount of accurate helioseismic data has open a new possibility to sound the stellar interiors and to test the stellar evolution theory. This has particularly impulsed a critical reexamination of the basic assumptions and physical inputs in solar modelling.

Approach to theoretical perspectives of “sexual harassment”: review and bibliometric analysis from social sciences

open access: yesFrontiers in Psychology, 2023
The main goal of this paper is to give an overlook of the current state of sexual harassment. In order to do so, we started making a synthesis of the main theoretical approaches to explain sexual harassment, trying to group the studies into different ...

Structural Disorder and Collective Behavior of Two-Dimensional Magnetic Nanostructures

open access: yesNanomaterials, 2021
Structural disorder has been shown to be responsible for profound changes of the interaction-energy landscapes and collective dynamics of two-dimensional (2D) magnetic nanostructures. Weakly-disordered 2D ensembles have a few particularly stable magnetic

Model Theory of Scattered Piecewise Interpretable Hilbert Spaces [PDF]

open access: yesarXiv, 2022
We study scattered piecewise interpretable Hilbert spaces from a model theoretic point of view. We establish strong connections between the Hilbert space structure theorems of [Chevalier Hrushovski 2021] and the model theoretic notions of canonical bases, one-basedness and model theoretic ranks.
