Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy
Advanced Healthcare Materials, EarlyView.Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

The sand grain and the butterfly. Instability in geodesy and geophysics
Annals of Geophysics, 1997 The problems of convergence of series in celestial mechanics and of certain series in geodesy (Molodensky's series and spherical harmonics) show similar features, involving a curious instability. This is imaginatively expressed as the « butterfly effect»

Influence of Low Europa Orbit design on gravity field recovery [PDF]
, 2021 The characterization of Europa's surface and interior ocean and ice shell is key to explore the habitability of the fourth largest moon of Jupiter. Europa Clipper will largely contribute to our knowledge of Europa with multiple dedicated flybys. However,

The average acceleration approach applied to gravity coefficients recovery based on GOCE orbits
Geodesy and Geodynamics, 2012 The average acceleration approach was applied to recover a gravity field model Model_ACA from GOCE precise science orbits from September 2 to November 2, 2010, and furthermore a so called sequential least square adjustment was used.

Theory of Artificial Anti-gravity
, 2022 To overcome the shortage of traditional flight mechanism, we propose a type of anti-gravity engine based on General Relativity. Natural anti-gravity phenomenon is found under special spacetime background by analysis geodesic motion of spacecraft and ...

Progress in Group Field Theory and Related Quantum Gravity Formalisms [PDF]
, 2020 Following the fundamental insights from quantum mechanics and general relativity, geometry itself should have a quantum description; the search for a complete understanding of this description is what drives the field of quantum gravity.
