P Systems with Anti-Matter

چکیده
After a short introduction to the area of membrane computing (a branch of natural computing), we introduce the concept of anti-matter in membrane computing. First we consider spiking neural P systems with anti-spikes, and then we show the power of anti-matter in cell-like P systems. As expected, the use of anti-matter objects and especially of matter/anti-matter annihilation rules, turns out to be rather powerful: computational completeness of P systems with anti-matter is obtained immediately, even without using catalysts. Finally, some open problems are formulated, too.

Finite iterative methods for solving systems of linear matrix equations over reflexive and anti-reflexive matrices
A matrix $Pintextmd{C}^{ntimes n}$ is called a generalized reflection matrix if $P^{H}=P$ and $P^{2}=I$. An $ntimes n$ complex matrix $A$ is said to be a reflexive (anti-reflexive) matrix with respect to the generalized reflection matrix $P$ if $A=PAP$ ($A=-PAP$). In this paper, we introduce two iterative methods for solving the pair of matrix equations $AXB=C$ and $DXE=F$ over reflexiv...
متن کاملInvolvement of Opioidergic and Sertoninergic systems in anti-nociceptive effect of Tanacetum parthenium
Introduction: Feverfew (Tanacetum parthenium) (T.p.) is widely used in folk medicine to treat many diseases. We reported the analgesic effect of T.p. flower and leaf previously. Present study is designed to find the mechanism underlying the anti-nociceptive effect of the aqueous extract of T.p. flower. Method: Based on our previous study, the dose 50 mg/kg i.p. of the T.p. aqueous extract had...
متن کاملارزیابی کارایی پروتئین A60 باکتری مایکوباکتریوم بوویس سویه BCG به عنوان پادگن تشخیصی
Tuberculosis is the most common infectious diseases. Current diagnostic methods are either slow or lack enough sensivity or specificity. Several mycobacterial antigens are involved in the complex interaction with the immune system of the host. They can be helpful for mycobacteria diagnosis. Antigen 60 (A60) is thermostable antigen found in Mycobacterium bovis and Mycobacterium tuberculosis...
متن کاملP-210: Evaluation of Anti-FSH Antibodies Levels as A Prognostic Marker in IVF Outcome
Background: The objective of this study is to establish importance of anti-FSH antibodies in IVF outcome. Materials and Methods: This research was designed based on evaluation of several articles from 2000 till 2012 about anti-FSH antibodies in IVF outcome. Results: Serum concentrations of anti-FSH IgG and IgA were linearly associated with poorer ovarian stimulation outcome. For example 1.0 AU ...
