Weak spectral equivalence and weak spectral convergence [PDF]
Czechoslovak Mathematical Journal, 1984 For the definitions of local spectrum, single valued extension property of an operator on a Banach space and related concepts see e.g., \textit{I. Colojoară} and \textit{C. Foiaş}, Theory of Generalized Spectral Operators (1968; Zbl 0189.442). In his paper, Rev. Roum. Math. Pur. Appl. 12, 733-736 (1967; Zbl 0156.382), \textit{F. H.

Advanced Functional Materials, EarlyView.Coating the standard polypropylene separator with a porous red phosphorous nanosheet greatly improves cycling performance in Li electrode cells. The phosphorus‐based surface chemistry deactivates electrolyte solvent decomposition and enhances the cleavage of F‐containing salt, resulting in an inorganic‐dominated electrolyte interphase (SEI) composition

On weak convergence of iterates in quantum Lp-spaces (p≥1)
International Journal of Mathematics and Mathematical Sciences, 2005 Equivalent conditions are obtained for weak convergence of iterates of positive contractions in the L1-spaces for general von Neumann algebra and general JBW algebras, as well as for Segal-Dixmier Lp-spaces (1 ...

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu
Advanced Functional Materials, EarlyView.From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).

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 ...

Weak convergence to the t-distribution [PDF]
We present a new limit theorem for random means: if the sample size is not deterministic but has a negative binomial or geometric distribution, the limit distribution of the normalised random mean is a t-distribution with degrees of freedom depending on ...

Advanced Functional Materials, EarlyView.This study presents a capacitive hydrogen sensor with a simple structure and process. Sonication‐induced Pd nanogaps modulate the effective electrode area in response to hydrogen concentration, resulting in capacitance changes within a range predefined by physical parameters.

Weak convergence of the sequential empirical processes of residuals in ARMA models [PDF]
This paper studies the weak convergence of the sequential empirical process $\hat{K}_n$ of the estimated residuals in ARMA(p,q) models when the errors are independent and identically distributed.

Weak Convergence to Brownian Excursion
The Annals of Probability, 1983 We give a concise proof, using rescaling, random time change and simple infinitesimal generator computations of the fact that Brownian excursion is the weak limit as $\varepsilon \rightarrow 0$ of tied down Brownian motion conditioned never to fall below $-\varepsilon$.

On Weak Convergence of Filtrations [PDF]
, 2001 A sequence of filtrations \(({\mathcal{F}^n_t})_{t{\leq}T}\) converges wealky to a filtration \(({\mathcal{F}}_t)_{t{\leq}T}\) iff, for all \(B{\in}{\mathcal{F}}_T\), the sequence of processes \((E[1_B\vert{\mathcal{F}}^n_t])_{t{\leq}T}\) converges in probability under the Skorokhod topology to the process \((E[1_B\vert{\mathcal{F}}_t])_{t{\leq}T ...
