State-independent contextuality sets for a qutrit
We present a generalized set of complex rays for a qutrit in terms of
parameter , a -th root of unity. Remarkably, when ,
the set reduces to two well known state-independent contextuality (SIC) sets:
the Yu-Oh set and the Bengtsson-Blanchfield-Cabello set. Based on the
Ramanathan-Horodecki criterion and the violation of a noncontextuality
inequality, we have proven that the sets with and are SIC, while
the set with is not. Our generalized set of rays will theoretically
enrich the study of SIC proof, and experimentally stimulate the novel
application to quantum information processing.Comment: 4 pages, 2 figures; revised versio
Sharp Contradiction for Local-Hidden-State Model in Quantum Steering
In quantum theory, no-go theorems are important as they rule out the
existence of a particular physical model under consideration. For instance, the
Greenberger-Horne-Zeilinger (GHZ) theorem serves as a no-go theorem for the
nonexistence of local hidden variable models by presenting a full contradiction
for the multipartite GHZ states. However, the elegant GHZ argument for Bell's
nonlocality does not go through for bipartite Einstein-Podolsky-Rosen (EPR)
state. Recent study on quantum nonlocality has shown that the more precise
description of EPR's original scenario is "steering", i.e., the nonexistence of
local hidden state models. Here, we present a simple GHZ-like contradiction for
any bipartite pure entangled state, thus proving a no-go theorem for the
nonexistence of local hidden state models in the EPR paradox. This also
indicates that the very simple steering paradox presented here is indeed the
closest form to the original spirit of the EPR paradox.Comment: 9 pages. Revised version for Scientific Report
By-products of rice processing: an overview of health benefits and applications
Our study was centred on the increasing literature associated with rice by-products and main components, especially those intended to combat cancer, improve plasma lipid levels or control the blood glucose levels. Rice byproducts, such as rice straw, rice husks, rice bran, rice germ and broken rice, are extensively abundant agricultural wastes from the rice industry, and the percentage of their production depends on the milling rate and type of rice. Among all rice by-products, rice bran has been extensively studied. It contains phytochemicals such as γ-oryzanol, vitamin E, mainly tocotrienols and dietary fibre. This paper reviews the existing literature on the potential role of rice by-products, focusing not only on the role of rice bran but also on the roles of other rice by-products, such as rice germ and rice husk, in the management of the diseases, investigating their various potential uses in the food industry and all possible properties that may contribute to these effects
