Differentiated policy implementation in food safety and animal welfare policymaking
European Policy Analysis, EarlyView.Abstract Agri‐food policies are in the midst of far‐reaching transitions, including the transformation towards sustainable production and food consumption. The European Green Deal and Farm to Fork Strategy prioritize food safety and animal welfare issues, aiming to transform food systems towards more sustainability.

Numerical Linear Algebra with Applications, Volume 30, Issue 1, January 2023., 2023 Abstract In this work, we focus on a fractional differential equation in Riesz form discretized by a polynomial B‐spline collocation method. For an arbitrary polynomial degree p$$ p $$, we show that the resulting coefficient matrices possess a Toeplitz‐like structure. We investigate their spectral properties via their symbol and we prove that, like for

A Subbuteo‐Inspired Rolling Isolation System for Protecting Rigid Blocks
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This study investigates a Subbuteo‐inspired rolling isolation system (RIS) as an effective means for protecting rigid blocks. The block is assumed to be rigidly connected to a curved base sector, allowing it to roll back and forth freely under dynamic excitations. The intrinsic trait of the proposed isolation concept is that the rigid block is

International Journal for Numerical Methods in Engineering, Volume 124, Issue 1, Page 119-158, 15 January 2023., 2023 Abstract In the quest for a numerical method for surface waves and wave‐induced effects applicable when linear or weakly nonlinear methods are insufficient, a three‐dimensional numerical wave tank assuming fully‐nonlinear potential‐flow theory is proposed.

Energy Science &Engineering, EarlyView.ABSTRACT This paper proposes an ejector‐expansion refrigeration cycle (EERC) with two evaporating temperatures to recover partial expansion work and greatly reduces the throttling loss of the other expansion valve connected to the evaporator compared with the conventional bievaporator refrigeration cycle (CBEC).

International Journal for Numerical Methods in Engineering, Volume 124, Issue 2, Page 402-433, 30 January 2023., 2023 Abstract Edge‐based and face‐based smoothed finite element methods (ES‐FEM and FS‐FEM, respectively) are modified versions of the finite element method allowing to achieve more accurate results and to reduce sensitivity to mesh distortion, at least for linear elements. These properties make the two methods very attractive. However, their implementation

Automorphism groups of some non-nilpotent Leibniz algebras
Researches in MathematicsLet $L$ be an algebra over a field $F$ with the binary operations $+$ and $[,]$. Then $L$ is called a left Leibniz algebra if it satisfies the left Leibniz identity: $[a,[b,c]]=[[a,b],c]+[b,[a,c]]$ for all $a,b,c\in L$. A linear transformation $f$ of $L$
