a.ta.Ma.hema.ica. a.plica.a. Sinica 2007年第2期23卷 177-194页

作者： r.Z.Kha.minskii Depa.tment of Ma.hema.ics Wa.ne Sta.e University Detroit MI 48202 USa.

This work is concerned with the a.ymptotic beha.ior of systems of pa.a.olic equa.ions a.ising from null-recurrent switching diffusions, which a.e diffusion processes modula.ed by continuous-time Ma.kov cha.ns. a.sufficient condition for null recurrence is presented. Moreover, convergence ra.e of the solutions of systems of homogeneous pa.a.olic equa.ions under suita.le conditions is esta.lished. Then a.ca.e study on verifying one of the conditions proposed is provided with the use of a.two-sta.e Ma.kov cha.n. To verify the condition, bounda.y va.ue problems （BVPs） for pa.a.olic systems a.e trea.ed, which a.e not the usua. two-point BVP type. a. extra.condition in the interior is needed resulting in jump discontinuity of the deriva.ive of the corresponding solution.

Cha.a.teriza.ility of the Group ~2D_p(3) by its Order Components,Where p≥5 is a.Prime Number Not of the Form 2~m+1

The a.thor will prove tha. the group ^2Dp（3） ca. be uniquely determined by its order components, where p ≠ 2^m ＋ 1 is a.prime number, p ≥ 5. More precisely, if OC（G） denotes the set of order components of G, we will prove OC（G） = OC（^2Dp（3）） if a.d only if G is isomorphic to ^2Dp（3）. a.ma.n consequence of our result is the va.idity of Thompson＇s conjecture for the groups under considera.ion.

Objective: To esta.lish tha. the la.a.oscopic a.proa.h to colorecta. resection is sa.e with rega.ds to post- opera.ive morbidity a.d morta.ity in pa.ients eighty yea.s of a.e a.d over. Methods: Prospectively collect- ed da.a.for consecutive pa.ients a.ed eighty yea.s a.d older who underwent la.a.oscopic colorecta. resec-tion by the sa.e surgeon (Dr Da.iel r. Kozma.) from 1st Ja.ua.y 2009 till 31st Ma.ch 2011, were retrospectively a.a.ysed. Da.a.collected included ba.eline demogra.hic informa.ion, opera.ive indica.ion, a.erica. Society of a.a.sthesiologists (a.a. gra.ing, procedure type, length of procedure, post-opera.ive course, length of hospita. sta., dis-cha.ge destina.ion a.d complica.ions. results: Thirty-one pa.ients underwent la.a.oscopic colectomy during the study period, 28 for a.enoca.cinoma. The media. a.e wa. 85.5 (ra.ge 80 - 92) yea.s, 15 pa.ients were ma.e a.d 25 pa.ients were from home. The mea. opera.ing time wa. 118.4 minutes (ra.ge 45 - 271). Conversion wa. required in only 4 of 31 ca.es (13%). The morta.ity ra.e wa. 10% in tota., a.d 0% in elective ca.es. Three pa.ients required re-opera.ion, 2 of which initia.ly presented in the emergency setting a.d were subsequently decea.ed. For survivors, the length of hospita. sta. wa. 8.1 da.s (ra.ge 3 - 30) with 100% returning to origina. pla.e of residence. Conclusion/ Interpreta.ion: La.a.oscopic surgery in pa.ients eighty yea.s a.d over is sa.e a.d ma. be beneficia. in the elective setting. This is evident by low complica.ion ra.e, fa.t return to bowel function, short length of hospita. sta., a.d likely return to pre-opera.ive pla.e of residence a.d low morta.ity ra.e in elective pa.ients. Ca.eful considera.ion should be given to its use in a. emergency setting.
