A quantum algorithm based on entanglement measure for classifying Boolean multivariate function into novel hidden classes

Abstract: In this paper, we propose a novel algorithm that solves a generalized version of the Deutsch-Jozsa problem. The proposed algorithm has the potential to classify an oracle U F , that represents an unknown Boolean function on n Boolean variables, to one of 2 n different classes instead of only two classes which are constant and balanced classes in the case of Deutsch-Jozsa algorithm. The proposed algorithm is based on the use of entanglement measure to explore 2 n - 2 additional classes compared to the standard Deutsch-Jozsa algorithm. In addition, the comparison between the proposed quantum algorithm and the classical one is investigated in details. The comparison shows that the proposed algorithm is faster when the number of Boolean variables exceed 14 variables.

Role of curcumin in regulating p53 in breast cancer: an overview of the mechanism of action.

Abstract: p53 is a tumor suppressor gene involved in various cellular mechanisms including DNA repair, apoptosis, and cell cycle arrest. More than 50% of human cancers have a mutated nonfunctional p53. Breast cancer (BC) is one of the main causes of cancer-related deaths among females. p53 mutations in BC are associated with low survival rates and more resistance to the conventional therapies. Thus, targeting p53 activity was suggested as an important strategy in cancer therapy. During the past decades, cancer research was focused on the development of monotargeted anticancer therapies. However, the development of drug resistance by modulation of genes, proteins, and pathways was the main hindrance to the success of such therapies. Curcumin is a natural product, extracted from the roots of Curcuma longa, and possesses various biological effects including anticancer activity. Previous studies proved the ability of curcumin to modulate several signaling pathways and biomolecules in cancer. Safety and cost-effectiveness are additional inevitable advantages of curcumin. This review summarizes the effects of curcumin as a regulator of p53 in BC and the key molecular mechanisms of this regulation.

Strong Energy-Transfer-Induced Enhancement of Luminescence Efficiency of Eu2+- and Mn2+-Codoped Gamma-AlON for Near-UV-LED-Pumped Solid State Lighting

Abstract: A series of Eu2+- and Mn2+-codoped γ-AlON (Al1.7O2.1N0.3) phosphors was synthesized at 1800 °C under 0.5 MPa N2 by using the gas-pressure sintering method (GPS). Eu2+ and Mn2+ ions were proved to enter into γ-AlON host lattice by means of XRD, CL, and EDS measurements. Under 365 nm excitation, two emission peaks located at 472 and 517 nm, resulting from 4f65d1 → 4f7 and 4T1(4G) → 6A1 electron transitions of Eu2+ and Mn2+, respectively, can be observed. Energy transfer from Eu2+ to Mn2+ was evidenced by directly observing appreciable overlap between the excitation spectrum of Mn2+ and the emission spectrum of Eu2+ as well as by the decreased decay time of Eu2+ with increasing Mn2+ concentration. The critical energy-transfer distance between Eu2+ and Mn2+ and the energy-transfer efficiency were also calculated. The mechanism of energy transfer was identified as a resonant type via a dipole–dipole mechanism. The external quantum efficiency was increased 7 times (from 7% for γ-AlON:Mn2+ to 49% for γ-AlON:Mn2+...
