Celestial Mechanics, Conformal Structures, and Gravitational Waves
, 2005 The equations of motion for $N$ non-relativistic particles attracting according to Newton's law are shown to correspond to the equations for null geodesics in a $(3N+2)$-dimensional Lorentzian, Ricci-flat, spacetime with a covariantly constant null ...

Imaging malaria parasites across scales and time
Journal of Microscopy, EarlyView.Abstract The idea that disease is caused at the cellular level is so fundamental to us that we might forget the critical role microscopy played in generating and developing this insight. Visually identifying diseased or infected cells lays the foundation for any effort to curb human pathology.

Invariant manifolds, discrete mechanics, and trajectory design for a mission to Titan [PDF]
, 2009 With an environment comparable to that of primordial Earth, a surface strewn with liquid hydrocarbon lakes, and an atmosphere denser than that of any other moon in the solar system, Saturn's largest moon Titan is a treasure trove of potential scientific ...

Investigation and reclassification of four mesosiderites—Implications for their formation
Meteoritics &Planetary Science, EarlyView.Abstract Mesosiderites are rare, differentiated meteorites, so‐called stony‐iron meteorites—they are impact breccias composed of an unusual mix of crustal basalt and pyroxenite, core‐derived metal, but no mantle materials. This odd mixture makes their origin enigmatic and has inspired many different formation theories over the last several decades ...

Applications to celestial mechanics
, 2022 Recently an asymptotic formula for the distance of the invariant manifolds of L3 in the RCP3BP when the mass parameter tends to zero was proven. In this study we numerically check the formula using high precision routines and give approximate values for the constants involved.

The Problem of Christ’s Acquired Knowledge
Modern Theology, EarlyView.Abstract Thomas Aquinas is universally applauded for his “courage and perspicacity” in eventually admitting an acquired knowledge in Christ. According to this doctrine, Christ, through the experience of his senses, came to know what he previously did not know.

Orbis Litterarum, EarlyView.Abstract Fluidity invigorates a utopian home in Chinese Canadian author Larissa Lai's Salt Fish Girl (2002). In the novel, the fishlike lesbian couple cyclically returns to their aquatic habitat between mortal reincarnations: from last‐century colonial South China to near‐future bio‐capitalistic Canada, where they recurrently experience displacement ...

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