New Model for Hill’s Problem in the Framework of Continuation Fractional Potential

open access: yesMathematical and Computational Applications
In this work, we derived a new type model for spatial Hill’s system considering the created perturbation by the parameter effect of the continuation fractional potential. The new model is considered a reduced system from the restricted three-body problem

Errant Implicature

open access: yesPhilosophical Perspectives, EarlyView.
ABSTRACT To measure is to err. Serving both numeric and non‐numeric measurement, the language of measurement refers to margins of error, within which measurement reports locate their measurements. Such reports and reasoning from them invoke what is known and what is known to be known about error‐strewn measurement to derive and contrast the ...

Reader Interaction with Graphic Devices in Early Modern English Printed Books☆

open access: yesRenaissance Studies, EarlyView.
Abstract Research into marginalia or reader annotations has become a well‐established branch of early modern book studies, shedding light on one of the ways in which manuscript and print coexisted and interacted in this period. The present study sets out to discover how readers engaged with printed graphic devices and with texts that contain such ...

Applications to celestial mechanics

open access: yes, 2023
This master's thesis consists in the study of the Elliptical Restricted Three-Body Problem, known as Elliptical RTBP. In particular, a first approach will be obtaining a compact formulation, through some changes of variables, in order to derive an adimensionalised and synodical system of equations. This will be done also for the Circular RTBP, in order

Time Tools

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Many core human activities require an understanding of time. To coordinate rituals, plan harvests and hunts, recall histories, keep appointments, and follow recipes, we need to grapple with invisible temporal structures like durations, sequences, and cycles. No other species seems to do this.

A Tale of Two Annies: Historical Memory, Archives and the Perpetuation of the Sinners to Angels Trope in American Sex Worker History

open access: yesGender &History, Volume 37, Issue 2, Page 606-620, July 2025.
Abstract As a historian of sex work, I analyse the power dynamics in the archiving practices and interpretation of sex worker lives, deconstructing the historic and current discourses shaping the possibilities for sex workers. In this article, I explore the legends of nineteenth‐century Madams Annie Cook and Annie Chambers.
