2 The ability of rendering objects invisible using a cloak – not detectable by an external observer – for concealing objects has been a tantalizing goal 1-6. Here, we demonstrate a cloak operating in the optical regime. The cloak operates at a wide bandwidth and conceals a deformation on a flat reflecting surface, under which an object can be hidden. The device is composed of nanometer size sil...

one of the most important steps lrz·hyy data interpretation, tracing certain horizons which is of critical ahmytand stratigraphy. the existence of noise in the data stage of the interpretation is difficult. in this article, applying the analysis principal component and a narrow selection of cross migration pnjrhyy given where reflections almost afqyand, a trace comes from that obtained undermin...

Data occurring in the form of frequencies are common in genetics-for example, in serology. Examples are provided by the AB0 group, the Rhesus group, and also DNA data. The statistical analysis of tables of frequencies is carried out using the available methods of multivariate analysis with usually three principal aims. One of these is to seek meaningful relationships between the components of a...

Recently, Tamanini & Danielski (2019) discussed the possibility to detect circumbinary exoplanets (CBPs) orbiting double white dwarfs (DWDs) with Laser Interferometer Space Antenna (LISA). Extending their methods and criteria, we discuss prospects for detecting around DWDs not only by LISA, but also Taiji, a Chinese space-borne gravitational-wave (GW) mission which has slightly better sensitivi...

different research and theoretical approaches have been adopted in the study of the space of music production. the space of production and consumption of culture in iran as a country in transition is diverse and heterogeneous. such a diversity and heterogeneity in itself causes problems for this space. the problem of this space, which in this research work has been defined as a small social spa...

In this paper, we define the concept of probabilistic like Menger (probabilistic like quasi Menger) space (briefly, PLM-space (PLqM-space)). We present some coupled fixed point and fixed point results for certain contraction type maps in partially order PLM-spaces (PLqM- spaces).
