Let $S_{2m}$ be the symmetric group, $h=(1\ 2)(3\ 4)\cdots(2m-1\ 2m)$ and $H=C(h)$. We consider structure of $gHg^{-1}\cap H$ for any $g\in S_{2m}$. prove permutations $g$ which makes have size polynomial in $m$ density zero.

In this paper the Bogdanov-Takens (BT) bifurcation of an 2m coupled neurons network model with multiple delays is studied, where one neuron is excitatory and the next is inhibitory. When the origin of the model has a double zero eigenvalue, by using center manifold reduction of delay differential equations (DDEs), the second-order and third-order universal unfoldings of the normal forms are ded...

?2 microglobulin (?2m) fibril has been recognized as the major factor of dialysis-related amyloidosis. elevated serum levels are thought to be the basis for tissue deposition. in order to evaluate the effect of cellulosis membrane (fb 110) and treatment duration on s?2m levels, we determined serum levels in 23 hemodialyzed patients with end-stage renal failure. s?2m levels were markedly elevate...

We show that for all integers m > 4 there exists a 2m × 2m ×m latin cuboid that cannot be completed to a 2m × 2m × 2m latin cube. We also show that for all even m / ∈ {2, 6} there exists a (2m−1) × (2m−1) × (m−1) latin cuboid that cannot be extended to any (2m−1)× (2m−1)×m latin cuboid.

Abstract For the $p$ -localized sphere $\mathbb {S}^{2m-1}_{(p)}$ with $p >3$ a prime, we prove that homotopy nilpotency satisfies $\mbox {nil}\ \mathbb {S}^{2m-1}_{(p)}<\infty$ , respect to any associative $H$ -structure on . We also {S}^{2m-1}_{(p)}= 1$ for all but finite number of primes Then, loop space associated -projective {S}^{2m-1}_{(p)}P(n-1)$ $m,n\ge 2$ and $m\mid p-1$ derive \...

We show that asymptotically almost surely a tree with m edges decomposes the complete bipartite graph K 2m,2m , a result connected to a conjecture of Graham and Häggkvist. The result also implies that asymptotically almost surely a tree with m edges decomposes the complete graph with O(m 2) edges. An ingredient of the proof consists in showing that the bipartition classes of the base tree of a ...

مگس میوه زیتون، (Rossi) Bactrocera oleae حشره‌ای مونوفاژ بوده و مهمترین آفت زیتون در سرتاسر جهان بویژه کشورهای مدیترانه می‌باشد. این پژوهش به منظور مطالعه تغییرات جمعیت مراحل مختلف زندگی برخی ویژگی‌های زیست‌شناسی دو سال منطقه طارم سفلی استان قزوین انجام شد. نتایج بررسی نشان داد که حشره سفلی، سه تا پنج نسل دارد. زمستان را صورت حشرات کامل پناهگاه‌های ندرت شفیره زیر بقایای گیاهی خاک‌های نرم باغ‌ها...

A  $ mu $-way  $ G $-trade ($ mu geq 2) $  consists of $ mu $ disjoint decompositions of some simple (underlying) graph $ H $ into copies of a graph $ G. $  The   number of copies of the  graph $ G $ in  each of the decompositions is the volume of the $ G $-trade and   denoted by $ s. $ In this paper, we determine all values  $ s $ for which there exists a $  mu $-way   $ K_{1,m} $-trade of  vo...

beta 2-Microglobulin (beta 2M) is a major constituent of amyloid fibrils in hemodialysis-associated amyloidosis, a complication of long-term hemodialysis patients. Amyloid fibril proteins were isolated from connective tissues forming carpal tunnels in hemodialysis patients with carpal tunnel syndrome. Two-dimensional polyacrylamide gel electrophoresis and Western blotting demonstrated that most...

First note that for any ρ ∈ (0, 1) and x ∈ R the function f (x) = x − 1 2 log ρ 2m 2 2x + 2πe(1 − ρ 2m) (1) is an monotonically increasing function with respect to x, because f ′ (x) = 2πe(1 − ρ 2m) ρ 2m 2 2x + 2πe(1 − ρ 2m) > 0. (2) By applying Shannon's EPI we have. h(s b |f a) ≥ 1 2 log ρ 2m 2 2h(sa|fa) + 2πe(1 − ρ 2m) (3) and thus, h(s a |f a) − h(s b |f a) ≤ h(s a |f a) − 1 2 log ρ 2m 2 2h...
