Advanced Functional Materials, EarlyView.This study examines how manufacturing uncertainties in Curie temperatures (1.5–2°C) affect multilayer active magnetic regenerators (AMR). While increasing the number of magnetocaloric layers boosts cooling power, performance degrades due to temperature variations.

Revisiting the Relationship between β and σ Convergence [PDF]
Pakistan Journal of Applied Economics, 2016 The paper questions the widely held assumptions about the relationship between absolute β-convergence and σ-convergence in the existing literature which states that β-convergence is a necessary condition for σ-convergence.

On Absolute Convergence of Multiple Fourier Series [PDF]
Transactions of the American Mathematical Society, 1947 Introduction. The results of this paper are extensions of corresponding results for simple Fourier series, given by one of the authors (cf. [5 ]) (1). The main problem was to study the relationship between the mean modulus of a function f(x) and series of the type E Icn I , /3 >0, where the cn are the Fourier coefficients of f(x).

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

On absolute almost convergence
Journal of Mathematical Analysis and Applications, 1991 By analogy with the sequence space \(\ell_ p\) \((p>0)\), the concept of \(\hat\ell_ p\) was first introduced in [the authors, Trans. Am. Math. Soc. 283, 729-739 (1984; Zbl 0546.46004)]. In this paper the authors present certain negative results for \(\hat\ell_ p\).

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Value without absolute convergence [PDF]
We address how the value of risky options should be assessed in the case where the sum of the probability-weighted payoffs is not absolutely convergent and thus dependent on the order in which the terms are summed (e.g., as in the Pasadena Paradox).

Advanced Functional Materials, EarlyView.MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Do gasoline prices converge in a unified Europe with non- harmonized tax rates? [PDF]
The paper presents univariate and panel unit root tests for gasoline and oil price convergence over the last decade. We test for the absolute versus relative version of the LOOP and estimate the speed of convergence as well as its development over time ...
