We analyze and show experimental results of the conditional purity, the quantum discord and other related measures of quantum correlation in mixed two-qubit states constructed from a pair of photons in identical polarization ...

In this manuscript, we appeal to Potential Theory to provide a sufficient condition for existence of distributional solutions to fractional elliptic problems with non-linear first-order terms and measure data ω:{(−Δ)su=| ...

Integer programming algorithms have some kind of exponential complexity in the worst case. However, it is also observed that data instances of similar sizes might have very different practical complexity when solved by ...

This article presents the design and development of a portable electronic device that allows to measure and visualize water turbidity data in the range from 0.1 to 999 NTU using a laser beam. The design of the transducer ...

We report on the realization of a capacitive dilatometer, designed for high-resolution measurements of length changes of a material for temperatures 1.4K ≤ T ≤ 300K and hydrostatic pressure P ≤ 250MPa. Helium ( 4He) is ...

The correct quality assessment of solar irradiance data allows public bodies, academic entities and nongovernmental organizations to plan and manage renewable energy resources more appropriately in Brazil. This study ...
