It is know. that the Allen-Chan equations satisfy the m.xim.m.principle. Is this true for num.rical schem.s？ To the best of our know.edge, the state-of-art stability fram.w.rk is the nonlinear energy stability w.ich has been studied extensively for the phase field type equations. In this w.rk, w. w.ll show.that a stronger stability under the infinity norm.can be established for the im.licit-explicit discretization in tim. and central finite difference in space. In other w.rds, this com.only used num.rical m.thod for the Allen-Cahn equation preserves the m.xim.m.principle.

An Intrinsic Rigidity Theorem.for Closed m.nim.l Hypersurfaces in S^5 w.th Constant Nonnegative Scalar Curvature

引用

Chinese Annals of m.them.tics,Series B 2018年第5期39卷 879-888页

作者： Bing tang Ling YANG School of m.them.tical Sciences Fudan University

Let m.4 be a closed m.nim.l hypersurface in S^5 w.th constant nonnegative scalar curvature. Denote by f_3 the sum.of the cubes of all principal curvatures, by g the num.er of distinct principal curvatures. It is proved that if both f_3 and g are constant,then m.4 is isoparam.tric. m.reover, the authors give all possible values for squared length of the second fundam.ntal form.of m.4. This result provides another piece of supporting evidence to the Chern conjecture.

Low.red testosterone in m.le obesity： m.chanism., m.rbidity and m.nagem.nt

Asian Journal of Andrology 2014年第2期16卷 223-231,I0008页

作者： m.rk Ng tang Fui Departm.nt of m.dicine Austin Health University of Melbourne Melbourne Departm.nt of Endocrinology Austin Health Melbourne Victoria Australia

w.th increasing m.dernization and urbanization of Asia, m.ch of the future focus of the obesity epidem.c w.ll be in the Asian region. Low.testosterone levels are frequently encountered in obese m.n w.o do not otherw.se have a recognizable hypothalam.c-pituitary-testicular （HPT） axis pathology. m.derate obesity predom.nantly decreases total testosterone due to insulin resistance-associated reductions in sex horm.ne binding globulin. m.re severe obesity is additionally associated w.th reductions in free testosterone levels due to suppression of the HPT axis. Low.testosterone by itself leads to increasing adiposity, creating a self-perpetuating cycle of m.tabolic com.lications. Obesity-associated hypotestosteronem.a is a functional, non-perm.nent state, w.ich can be reversible, but this requires substantial w.ight loss. w.ile testosterone treatm.nt can lead to m.derate reductions in fat m.ss, obesity by itself, in the absence of sym.tom.tic androgen deficiency, is not an established indication for testosterone therapy. Testosterone therapy m.y lead to a w.rsening of untreated sleep apnea and com.rom.se fertility. w.ether testosterone therapy augm.nts diet- and exercise-induced w.ight loss requires evaluation in adequately designed random.zed controlled clinical trials.
