The densification mechanism of squeeze casting

The solidification process during squeeze casting is analyzed based on the classical solidification and plastic deformation theory. The linear relationship between punch velocity and the solidification rate is established if the density change of m...

On the compatibility of quantum instruments

Incompatibility of quantum devices is a useful resource in various quantum information theoretical tasks, and it is at the heart of some fundamental features of quantum theory. While the incompatibility of measurements and quantum channels is well-st...

On the formation and propagation of pulses in ether

In 1746 Euler publishes E88 -- Nova theoria lucis et colorum (A new theory of light and colors) in five chapters. This is an annotated translation of Chapter II - De formatione ac propagatione pulsuum (On the formation and propagation of pulses in et...

Field redefinition's help in constructing non-abelian gauge theories

We study, using the example of general covariance, to what extent a would-be non-abelian extension of free field abelian gauge theory can be helped by a field redefinition; answer - not much! However, models resulting from dimensional reduction also...

York time in JT gravity

The notion of time in general relativity must arise from an internal clock, i.e., a degree of freedom in the gravitational theory internal to the system that can serve the role of a physical clock. One such internal notion of time is the York time, c...

Adding a lot of Cohen reals by adding a few I

In this paper we produce models $V_1\subseteq V_2$ of set theory such that adding $κ$-many Cohen reals to $V_2$ adds $λ$-many Cohen reals to $V_1$, for some $λ>κ$. We deal mainly with the case when $V_1$ and $V_2$ have the same cardinals....

Transients from Initial Conditions in Cosmological Simulations

We study the impact of setting initial conditions in numerical simulations using the standard procedure based on the Zel'dovich approximation (ZA). As it is well known from perturbation theory, ZA initial conditions have incorrect second and higher...

Multi-Vacuum Initial Conditions and the Arrow of Time

Depending on the type and arrangement of metastable vacua in the theory, initial conditions in a de Sitter vacuum with arbitrarily large entropy can be compatible with the observed arrow of time, if the causal patch or related measures are used to re...

Théorie de la réduction pour les groupes p-divisibles

Starting from our work on Harder-Narasimhan filtrations of finite flat group schemes over a $p$-adic field, we developp a theory of Harder-Narasimhan filtrations for $p$-divisible groups. We apply this to the study of the geometry of period morphisms...

Reshaping limit diagrams and cofinality in higher category theory

We present some results on (co)limits of diagrams in $\infty$-categories, as well as those in $(n, 1)$-categories. In particular, we deduce a way to reshape colimit diagrams into simplicial ones, and a characterisations of $n$-cofinality for functor...
