This study examined the biochemical characteristics of a-amylase and hor- monal （adipokinetic hormone： AKH） stimulation of a-amylase activity in the cockroach （Periplaneta americana） midgut. We applied two AKHs in vivo and in vitro, then measured resultant amylase activity and gene expression, as well as the expression of AKH receptor （AKHR）. The results revealed that optimal amylase activity is characterized by the follow- ing： pH： 5.7, temperature： 38.4 ℃, Km （Michaelis-Menten constant）： 2.54 mg starch/mL, and Vmax （maximum reaction velocity）： 0.185 μmol maltose/mL/min. In vivo application of AKHs resulted in significant increase of amylase activity： by two-fold in the gastric caeca and 4-7 fold in the rest of the midgut. In vitro experiments supported results seen in vivo： a 24-h incubation with the hormones resulted in the increase of amylase activity by 1.4 times in the caeca and 4-9 times in the midgut. Further, gene expression analyses reveal that AKt-IR is expressed in both the caeca and the rest of the midgut, although expression levels in the former were 23 times higher than levels in the latter. A similar pattern was found for the amylase （AMY） gene. Hormonal treatment did not affect the expression of either gene. This study is the first to provide evidence indicating direct AKH stimulation of digestive enzyme activity in the insect midgut, supported by specific AKHR gene expression in this organ.

We study large time asymptotics of solutions to the Korteweg-de Vries-Burgers equation ut＋uux-uxx＋uxxx=0,x∈R,t〉0. We are interested in the large time asymptotics for the case when the initial data have an arbitrary size. We prove that if the initial data u0 ∈H^s （R）∩L^1 （R）, where s 〉 -1/2, then there exists a unique solution u （t, x） ∈C^∞ （（0,∞）;H^∞ （R）） to the Cauchy problem for the Korteweg-de Vries-Burgers equation, which has asymptotics u（t）=t^-1/2fM（（·）t^-1/2）＋0（t^-1/2） as t →∞, where fM is the self-similar solution for the Burgers equation. Moreover if xu0 （x） ∈ L^1 （R）, then the asymptotics are true u（t）=t^-1/2fM（（·）t^-1/2）＋O（t^-1/2-γ） where γ ∈ （0, 1/2）.

This paper evaluates possible directional effects from strong ground motions recorded during the last four significant subcrustal earthquakes produced in the Vrancea seismic zone（Romania） in August 1986（Mw=7.1）,May 1990（Mw=6.9 and 6.4） and October 2004（Mw=6.0）.Several measures of the horizontal component of the ground motion given in the literature（Boore et al.,2006;Boore,2010） are computed and are related to the geometric mean of the as-recorded horizontal *** method is applied in order to quantify the influence of the earthquake magnitude and of the soil class on some strong ground motion parameters（*** intensity,PGV/PGA,or mean period TM）.The study of the directional effects is performed using the distribution of IJMAand of the rotation angle corresponding to a measure of the horizontal component of the ground motion（RotD 100） and the results reveal a visible directional pattern for IJMA,while in the case of RotD100 the directional patterns are less visible.

The volume collects papers from talks given at QMath11 -- Mathematical Results in Quantum Physics, which was held in Hradec Kr??lov??, September 2010. These papers bring new and interesting results in quantum mechanics and information, quantum field theory, random systems, quantum chaos, as well as in the physics of social systems. Part of the contribution is dedicated to Ari Laptev on the occasion of his 60th birthday, in recognition of his mathematical results and his service to the community. The QMath conference series has played an important role in mathematical physics for more than two decades, typically attracting many of the best results achieved in the last three-year period, and the meeting in Hradec Kralove was no exception
