Artemisinin extracted from Artemisia annua L. is the best medicine with the highest efficiency, the most effective and the lowest toxicity in treating ague nowadays. At present, most studies focus on artemisinin and its derivatives, while the study and report about the other active components are rare. This paper purposed to further discover new indication of Artemisia annua L. connecting with ...
Background and purpose: Adenocarcinoma gastric cancer is one of the most common cancers of upper gastrointestinal tract. Many natural compounds are known to have anti-tumor activities through induction of tumor cell apoptosis. Tribulus terrestris is a plant with antioxidant and anti-inflammatory effects that has been recommended in the world and Iranian traditional medicine. These effects have ...
A study is presented of right (left) coprime decompositions of a collection of N -periodic rational matrices, with some ordered structure. From a block-ordered right coprime decomposition of a rational matrix of the given periodic collection, the corresponding block-ordered right coprime decompositions of the remaining matrices of the collection are constructed. In addition, those decomposition...
We introduce a new number–theoretic spin chain and explore its thermodynamics and connections with number theory. The energy of each spin configuration is defined in a translation–invariant manner in terms of the Farey fractions, and is also expressed using Pauli matrices. We prove that the free energy exists and exhibits a unique phase transition at inverse temperature β = 2. The free energy i...
A fit to the present cosmic ray positron fraction can be considerably improved, if in addition to the positron production by nuclear interactions in the universe the possible contribution from supersymmetric dark matter annihilation is taken into account. We scan over the complete SUSY parameter space of the Constrained Minimal Supersymmetric Model (CMSSM) and find that in the acceptable region...
Here we examine Dodgson's Method, a fraction-free methods for computing determinants. In some cases, this method fails due to division by zero. We propose a workaround for Dodgson's Method that ensures it also can be used to compute the determinant of any integer matrix.
