We study the Maker‐Breaker k‐clique game played on the edge set of the random graph G(n, p). In this game, two players, Maker and Breaker, alternately claim unclaimed edges of G(n, p), until all the edges are claimed. Maker wins if he claims all the edges of a k‐clique; Breaker wins otherwise. We determine that the threshold for the graph property that Maker can win this game is at , for all k > 3, thus proving a conjecture from Ref. [Stojakovi? and Szabó, Random Struct Algor 26 (2005), 204–223]. More precisely, we conclude that there exist constants such that when the game is Maker's win a.a.s., and when it is Breaker's win a.a.s. For the triangle game, when k = 3, we give a more precise result, describing the hitting time of Maker's win in the random graph process. We show that, with high probability, Maker can win the triangle game exactly at the time when a copy of K5 with one edge removed appears in the random graph process. As a consequence, we are able to give an expression for the limiting probability of Maker's win in the triangle game played on the edge set of G(n, p). © 2013 Wiley Periodicals, Inc. Random Struct.

Laser ablation of Mn target in vacuum and in the presence of CH4 was
studied under 308 nm laser irradiation. Time-resolved emission using gated
detection and scanning monochromator and absorption using the cavity ring-down
spectroscopy were used to study vaporized plume. In the CH4 atmosphere we
observed transitions identified as C2 and MnH bands, while these spectral
features were not detected in emission spectra. This is a clear evidence of
importance in combining both spectroscopic techniques in laser vaporized plume study. 相似文献

Cell membrane is highly sensitive to irradiation which, acting directly or indirectly, may disturb functions of constitutive
proteins including membrane enzymes. Plasma membrane surface-located enzyme chain of ecto-nucleotide triphospho diphosphohydrolases
(NTPDases) and 5′-nucleotidase are involved in termination of cell purinergic signalization by hydrolyzing extracellular,
excitatory adenosine triphosphate (ATP), as well as nucleotide di-, and mono-phosphate (ADP and AMP) to neuroprotective adenosine.
Extracellular ATP, ADP, and AMP hydrolyzes were examined in purified synaptic plasma membranes after whole-body acute irradiation.
All measurements were done 24 h after irradiation of developing (15-, 30-day-old) and adult (90-day-old) rats with low (50
cGy) and high (2 Gy) dose of gamma-rays. Both, high and low doses inhibited nucleotide hydrolyses in 15-day-old rats; in 30-day-old
rats low dose of radiation inhibited ADP and AMP hydrolyses while high dose inhibited only ATP hydrolyse. In adult rats high
dose induced no effects, while low dose stimulated nucleotides hydrolyses. According to obtained results it was concluded
that ecto-nucleotidases of young rats are more sensitive to irradiation, since even low dose induces inhibition of ecto-nucleotidases
activities. Ionizing radiation, by decreasing brain nucleotide hydrolyses in developing rats, induces accumulation of ATP
and decreases production of adenosine in synaptic cleft which could be neurocytotoxic. On the contrary, in adult rats low
dose of radiation stimulates NTPDase and 5′-nucleotidase activity and protective adenosine production which indicates protective
and adaptive mechanisms developed in adult brain neuronal cells.

Starting from a suitable fixed point relation, a new family of iterative methods for the simultaneous inclusion of multiple complex zeros in circular complex arithmetic is constructed. The order of convergence of the basic family is four. Using Newtons and Halleys corrections, we obtain families with improved convergence. Faster convergence of accelerated methods is attained with only few additional numerical operations, which provides a high computational efficiency of these methods. Convergence analysis of the presented methods and numerical results are given.

We present a simple method to obtain reliable ground-state entropies of the q-state Potts antiferromagnet in an external magnetic field. As an example, the ground-state entropy for the triangular lattice is established for all q. In the particular case q = 2, our method gives results which coincide with the first-order approximation obtained by the corner transfer matrix method. 相似文献

Summary We consider the Dirichlet problem for the equation Lε(u) ≡ uxx+ɛuyy++A(x, y)ux−B(y)uy+C(x, y)u=F(x, y) where B(y)>0 and ɛ is a small positive parameter. An asymptotic formula is proved, from which it follows
that in a suitable part of the domain of definition u(x, y, ɛ)→U(x, y) as ɛ→0+, where U(x, y) is the solution of the corresponding
boundary - value problem for the reduced equation L0(U)≡Uxx+A(x, y)Ux−B(y)U+C(x, y)U=F(x, y).
