Several new strategies to extract CKM phases, including a determination of γ from Bs(d) → J/ψKS decays and a general approach, which makes use of the angular distributions of certain Bd,s modes, such as Bd → J/ψ ρ 0 and Bs → J/ψ φ, are discussed. Special emphasis is put on a simultaneous determination of β and γ with the help of the decays Bd → π π and Bs → K K, which relies only on the U -spin...

The high-impact precipitation events that regularly affect the western Mediterranean coastal regions are still difficult to predict with the current prediction systems. Bearing this in mind, this paper focuses on the superensemble technique applied to the precipitation field. Encouraged by the skill shown by a previous multiphysics ensemble prediction system applied to western Mediterranean pre...

A low-cost efficient electrocatalyst for both oxygen reduction reaction (ORR) and evolution (OER) is urgently required the commercialization of Zn-air batteries. Herein, CoMn nanoalloys encapsulated in nitrogen-doped hollow carbon architectures (CoMn@NHC) as dual electrocatalysts batteries were developed successfully. The obtained CoMn@NHC nanohybrid expresses excellent electrocatalytic perform...

In the present study, we carried out chemical synthesis and characterization of Fe3O4@PEG-Au as a magnetic nanocomposite in aqueous solution by chemical co-precipitation of Fe3+ and Fe2+ ions and encapsulated by poly (ethylene glycol) (PEG) in order to enhancing hydrophilicity, biocompatibility and immobilizing gold ions in the presence of NaBH4 as a reducing agent. Nanostructures were characte...

This paper presents a numerical study that aims at investigating the effects of different parameters on dynamic performance single and multi-layer encapsulated phase material (PCM) thermocline tanks. A transient, one-dimensional, two-phase, concentric-dispersion model is formulated to evaluate such performance. Encapsulated paraffin waxes having melting-points are used as PCMs, with water heat ...

Side eeects in imperative programming languages are ubiquitous, which makes it dii-cult to reason about programs in other than operational terms. Functional programming languages, on the other hand, claim the advantage that equational logics are suucient for reasoning, but at the that often useful eeects, such as interactive input, exceptions, and explicit updates of state cannot be accommodate...
