The macroscopic tensile plasticity of bulk metallic glasses (BMGs) is highly desirable for various engineering applications. However, upon yielding, plastic deformation of BMGs is highly localized into narrow shear bands and then leads to the "work softening" behaviors and subsequently catastrophic fracture, which is the major obstacle for their structural applications. Here we report that macr...

The main purpose of this paper is to obtain sufficient conditions for existence of points of coincidence and common fixed points for three self mappings in $b$-metric spaces. Next, we obtain cone $b$-metric version of these results by using a scalarization function. Our results extend and generalize several well known comparable results in the existing literature.

Este artículo propone un conjunto de criterios para seleccionar cómics en el contexto del plan lector enseñanza media. Para ello se consideró lo planteado las Bases Curriculares chilenas (2015, 2019) y los Programas Estudio Lengua Literatura (Ministerio Educación, 2016 – 2020), junto con referentes teóricos claves como Serafini (2015), Bordes (2017), McCloud (2014) Luch (2012). Desde dichos pro...

I characterize the class of (possibly incomplete) preference relations over lotteries which can be represented by a compact set of (continuous) expected utility functions that preserve both indifferences and strict preferences. This finding contrasts with the representation theorem of Dubra, Maccheroni and Ok (2004) which typically delivers some functions which do not respect strict preferences...

We study the dynamical spontaneous scalarization of charged black hole in asymptotically anti--de Sitter spacetimes Einstein-Maxwell-scalar models. Including various nonminimal couplings between scalar field and Maxwell field, an initial scalar-free suffers tachyonic instability, both irreducible mass grow exponentially at early times saturate late times. For fractional coupling, we find that, ...

Particular couplings between a scalar field and the Gauss-Bonnet invariant lead to spontaneous scalarization of black holes. Here we continue our work on simulating this phenomenon in context binary hole systems. We consider negative coupling for which black-hole spin plays major role process. find two main phenomena: (i) dynamical descalarization, initially scalarized holes form an unscalarize...

In this paper, by virtue of separation theorems convex sets and scalarization functions, some minimax inequalities are first considered. As applications, existence vector equilibrium problems with different order structures were also obtained.

Most evolutionary multi-objective optimization (EMO) methods use domination and nichepreserving principles in their selection operation to find a set of Pareto-optimal solutions in a single simulation run. However, classical generative multi-criterion optimization methods repeatedly solve a parameterized single-objective problem to achieve the same. Due to lack of parallelism in the classical g...
