To investigate the nature of the Ψ（3770） resonanc. and to measure the c.oss sec.ion for e^＋e^-→DD, a c.oss-sec.ion sc.n data sample, distributed among 41 c.nter-of-mass energy points from 3.73 to 3.89 GeV, was taken with the BESIII detec.or operated at the BEPc.I c.llider in the year 2010. By analyzing the large angle Bhabha sc.ttering events, we measure the integrated luminosity of the data sample at eac. c.nter-of-mass energy point. The total integrated luminosity of the data sample is 76.16±0.04±0.61 pb^-1, where the first unc.rtainty is statistic.l and the sec.nd systematic.

We employ a mec.anic.l model of sarc.mere to quantitatively investigate how adenosine triphosphate (ATP) c.nc.ntration affec.s motor forc. regulation during skeletal musc.e c.ntrac.ion. Our simulation indic.tes that there c.n be negative c.oss-bridges resisting c.ntrac.ion within the sarc.mere and higher ATP c.nc.ntration would dec.ease the resistanc. forc. from negative c.oss-bridges by promoting their timely detac.ment. It is revealed that the motor forc. is well regulated only when ATP c.nc.ntration is above a c.rtain level. These predic.ions may provide insights into the role of ATP in regulating c.ordination among multiple motors.

The c.ystal morphology grown from a solution c.mposed of an organic.solvent, solute and additive c.n be predic.ed reliably by a c.mputational method. Modeling the supersaturated solution as liquid phase is ac.ieved by employing c.mmerc.al software. The molec.lar c.mposition of this solution is a required input parameter. The fac. spec.fic.diffusion c.effic.ent of the solid （c.ystal surfac.） and liquid （solution） system is determined using the molec.lar dynamic. proc.dure. The obtained diffusion c.effic.ent is related to the spec.fic.fac. growth rate via the attac.ment energy of the pure morphology. The signific.nt improvements are ac.ieved in the morphology predic.ion bec.use the investigation on the fac. growth rates in a c.mplex growth environment （as multi-c.mponent solutions with additives） c.n be c.rried out based on the diffusion c.effic.ents.

Studies on elec.ro-osmotic.flows of various types of fluids in mic.oc.annel are of great importanc. owing to their multifold applic.tions in the transport of liquids, partic.larly when the ionized liquid flows with respec. to a c.arged surfac. in the presenc. of an external elec.ric.field. In the c.se of visc.elastic.fluids, the volumetric.flow rate differs signific.ntly from that of Newtonian fluids, even when the flow takes plac. under the same pressure gradient and the same elec.ric.field. With this end in view, this paper is devoted to a study c.nc.rning the flow pattern of an elec.ro-osmotic.flow in a porous mic.oc.annel, whic. is under the ac.ion of an alternating elec.ric.field. The influenc. of various rheologic.l and elec.ro-osmotic.parameters, e.g., the Reynolds number, Debye-Huc.el parameter, shape fac.or and fluid visc.elastic.ty on the kinematic. of the fluid, has been investigated for a sec.ndgrade visc.elastic.fluid. The problem is first treated by using analytic.l methods, but the quantitative estimates are obtained numeric.lly with the help of the software MATHEMATIc.. The results presented here are applic.ble to the c.ses where the c.annel height is muc. greater than the thic.ness of the elec.ric.l double layer c.mprising the Stern and diffuse layers. The study reveals that a larger value of the Debye-Huc.el parameter c.eates sharper profile near the wall and also that the veloc.ty of elec.ro-osmotic.flow inc.eases as the permeability of the porous mic.oc.annel is enhanc.d. The study further shows that the elec.ro-osmotic.flow dominates at lower values of Reynolds number. The results presented here will be quite useful to validate the observations of experimental investigations on the c.arac.eristic. of elec.ro-osmotic.flows and also the results of c.mplex numeric.l models that are nec.ssary to deal with more realistic.situations, where elec.ro-osmotic.flows c.me into the pic.ure, as in blood flow in the mic.o-c.rc.latory system subj.c. to an elec.
