Inspired by the recent measurement of $CP$ asymmetry in individual mode on LHCb, we study $D\to \pi\pi$ system isospin and topological analysis. The ratio between penguin tree amplitudes $P/(T+C)$ is found to be greater than two most values relative strong phase. And $D^0\to \pi^0\pi^0$ a potential reveal order $10^{-3}$, which would observed Belle II future. large might understood $t$-channel ...

We give lower bounds on the largest singular value of arbitrary matrices, some of which are asymptotically tight for almost all matrices. To study when these bounds are exact, we introduce several combinatorial concepts. In particular, we introduce regular, pseudo-regular, and almost regular matrices. Nonnegative, symmetric, almost regular matrices were studied earlier by Ho¤man, Wolfe, and Ho¤...

Let $R$ be a commutative ring with $1 \ne 0$ and let $m$ and
 $n$ integers $1\leq n < m$. A proper ideal $I$ of is
 called an $(m, n)$-closed if whenever $a^m \in I$ for
 some $a\in R$ implies $a^n I$. $ f:A\rightarrow B$ a
 homomorphism $J$ $B.$ This paper
 investigates the concept $(m,n)$-closed ideals in the
 amalgamation $A$ $B$ along respect $f$ denoted by&...

In prior work, Cimini has presented Lang-n-Send, a pi-calculus with language definitions. this paper, we present an extension of calculus called Lang-n-Send+m. First, revise Lang-n-Send to work transition system specifications rather than its specifications. This revision allows the use negative premises in deduction rules. Next, extend monitors and ability sending receiving regular expressions...

background: the success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. the present study investigated the periodontal parameters at the end of the orthodontic treatment in patients with the ...

phosphorus (p), in the form of phosphate ion (pi), is a vital element contributing in biomolecule structures, metabolic reactions, signaling pathways and energy transfer within the living cells. the objective of the present study was to assess the influence of fungal infection on pi metabolism in compare to the effects of phosphate stress in arabidopsis. quantification of total p contents showe...

Let $f(\mathbf z,\bar{\mathbf z})$ be a convenient Newton non-degenerate mixed polynomial with strongly polar non-negative weighted homogeneous face functions. We consider regular simplicial cone subdivision $\Sigma^*$ which is admissible for $f$ and take the toric modification $\hat{\pi} : X \to \mathbb{C}^n$ associated $\Sigma^*$. show that resolves topologically singularity of hypersurface g...
