      We estimate the chemical freeze-out of light nuclear clusters for NICA energies of above 2 A GeV. On the one hand we use results from the low energy domain of about 35 A MeV, where medium effects have been shown to be important to explain e...

      We study different behavioral metrics, such as those arising from both branching and linear-time semantics, in a coalgebraic setting. Given a coalgebra α ⁣:X→HX\alpha\colon X \to HXα:X→HX for a functor H ⁣:Set→SetH \colon \mathrm{Set}\to \mathrm{Set}H:Set→Set, we define...

      Conservation of angular momentum depends on the existence of rotational symmetry. However, even in systems where this symmetry is broken, flipping between angular momentum eigenstates often requires an activation energy. Here we discuss an ...

      The purpose of this paper is to study minimal modular extensions of braided fusion categories, with emphasis on minimal modular extensions of super-Tannakian fusion categories. We define actions of finite super-groups on fermionic fusion ca...

      Axiomatic foundation of quantum measurements and survival effect

      The axiomatic theory of quantum first-kind measurements is developed in a rigorous form based on five Postulates. The measurement theory for observable with continuous spectrum is given in a rigged Hilbert space. This approach also describe...

      Let GGG be a real classical group (including the real metaplectic group). We consider a nilpotent adjoint orbit Oˇ\check{\mathcal O}Oˇ of Gˇ\check GGˇ, the Langlands dual of GGG (or the metaplectic dual of GGG when GGG is a real metaplectic gro...

      Choreographic programming promises a simple approach to the coding of concurrent and distributed systems: write the collective communication behaviour of a system of processes as a choreography, and then the programs for these processes are...

      The modeling of emergent swarm intelligence constitutes a major challenge and it has been tackled in a number of different ways. However, existing approaches fail to capture the nature of swarm intelligence and they are either too abstract ...

      Homotopical algebra for Lie algebroids

      We construct Quillen equivalent semi-model structures on the categories of dg-Lie algebroids and L∞L_\inftyL∞​-algebroids over a commutative dg-algebra in characteristic zero. This allows one to apply the usual methods of homotopical algebra t...

      In this paper we propose spatial filters for a linear regression model which are based on the minimum-variance pseudo-unbiased reduced-rank estimation (MV-PURE) framework. As a sample application, we consider the problem of reconstruction o...
