Let (K, v) be a complete discretely valued field of characteristic zero with an algebraically closed residue field of positive characteristic. Let σ : K → K be a continuous automorphism of K inducing a Frobenius automorphism on the residue field. We prove quantifierelimination for (K, v, σ) in a language with angular component maps and in a language with predicates on leading terms. The proof p...

runoff collect used for to minimize losses and strengthen water resources in watersheds.countries like some areas of iran are facing to water scarcity, faced with unsuitable distribution of rainfall. by expanding the use of water sources, using the principles of runoff from rainfall can be effective to solve the problem of water shortage.in order to estimate the runoff in watershedsthere are se...

The present paper focuses on the two time scale dynamics generated by 2D polynomial noninvertible maps T of (Z0−Z2) and (Z1−Z3−Z1) types. This symbolism, specific to noninvertible maps, means that the phase plane is partitioned into zones Zk, where each point possesses the k real rank-one preimages. Of special interest here is the structure of slow and fast motion sets of such maps. The formati...

Peptide mapping of underivatized tryptic digests of bovine and chick intestinal calcium-binding proteins has been accomplished by high performance liquid chromatography (HPLC). High precision analysis of nanomolar quantities of peptides were achieved in less than 1 h (recycle time). Peak resolution and definition are superior compared to conventional techniques and recoveries of both small (4-r...

UNLABELLED PConPy is an open-source Python module for generating protein contact maps, distance maps and hydrogen bond plots. These maps can be generated in a number of publication-quality vector and raster image formats. Contact maps can be annotated with secondary structure and hydrogen bond assignments. PConPy offers a more flexible choice of contact definition parameters than existing toolk...

Let (K;v) be a complete discretely valued eld of characteristic zero with an algebraically closed residue eld of positive characteristic. Let : K ! K be a continuous automorphism of K inducing a Frobenius automorphism on the residue eld. We prove quantiier-elimination for (K;v;) in a language with angular component maps and in a language with predicates on leading terms. The proof passes throug...

The electrocardiographic imaging (ECGI) inverse problem is highly ill-posed and regularization is needed to stabilize the problem and to provide a unique solution. When Tikhonov regularization is used, choosing the regularization parameter is a challenging problem. Mathematically, a suitable value for this parameter needs to fulfill the Discrete Picard Condition (DPC). In this study, we propose...

For a compact oriented 3-manifold with torus boundary the adjoint Reidemeister torsion is defined as function on $\mathrm{SL}_2(\mathbb{C})$-character variety depending choice of curve. Under reasonable assumptions, it conjectured that satisfies certain type vanishing identities. In this paper, we prove conjecture holds for all hyperbolic twist knot exteriors by using Jacobi's residue theorem.

in this study the effect of different nitrogen source substrates on the amount of chitosan production by aspergillus niger was investigated. a. niger ptcc 5012 from the persian type culture collection (ptcc) was grown on soy bean, corn seed and canola residues at 30 °c for specified cultivation days under sterilized conditions. chitosan was extracted from the fungal mycelia using hot alkaline a...
