In th.s paper we extend th. duality(■)*= h.(Rd) to generalized Campanato spaces with.variable growth.condition Lp,φ(Rd) instead of BMO(Rd). We also extend th. ch.racterization of Cc∞omp(Rd)BMO(Rd)by Uch.yama(1978) to ■. Moreover, using th.s ch.racterization, we prove th. boundedness of singular and fractional integral operators on ■.Th. function space Lp,φ(Rd) treated in th.s paper covers th. case th.t it is coincide with.Lipαon one area, with.BMO on anoth.r area and with.th. Morrey space on th. oth.r area, for example.

Th. immune-stromal cell interactions play a key role in h.alth.and diseases. In periodontitis, th. most prevalent infectious disease in h.mans, immune cells accumulate in th. oral mucosa and promote bone destruction by inducing receptor activator of nuclear factor-κB ligand (RANKL) expression in osteogenic cells such.as osteoblasts and periodontal ligament cells. h.wever, th. detailed mech.nism underlying immune–bone cell interactions in periodontitis is not fully understood. h.re, we performed single-cell RNAsequencing analysis on mouse periodontal lesions and sh.wed th.t neutroph.l–osteogenic cell crosstalk is involved in periodontitis-induced bone loss. Th. periodontal lesions displayed marked infiltration of neutroph.ls, and in silico analyses suggested th.t th. neutroph.ls interacted with.osteogenic cells th.ough.cytokine production. Among th. cytokines expressed in th. periodontal neutroph.ls, oncostatin M (OSM) potently induced RANKL expression in th. primary osteoblasts, and deletion of th. OSM receptor in osteogenic cells significantly ameliorated periodontitis-induced bone loss. Epigenomic data analyses identified th. OSM-regulated RANKL enh.ncer region in osteogenic cells, and mice lacking th.s enh.ncer sh.wed decreased periodontal bone loss wh.le maintaining ph.siological bone metabolism. Th.se findings sh.d ligh. on th. role of neutroph.ls in bone regulation during bacterial infection, h.gh.igh.ing th. novel mech.nism underlying osteoimmune crosstalk.

A nuclear astroph.sics experiment was performed at CRIB (CNS low-energy Radioactive-Ion Beam separator) on Mar. 2011. Th. goal of th.s experiment is to study th. reaction rate of 18Ne(α, p)21Na reaction, wh.ch.migh. be a key breakout reaction from th. h.t CNO cycle to rp-process in X-ray burst and nova. Yet its reaction rate is poorly known.

^(14)O(α, p)^(17)F是天体X射线暴中重要的突破反应。本工作通过厚靶方法测量其逆反应~1h.^(17)F,α)^(14)O的反应截面来研究这一关键反应。本实验工作是在日本东京大学原子核科学研究中心(CNS)的低能次级束流线(CRIB)上完成的,后续的扣除本底实验是在兰州放射性束流线(RIBLL1)上完成的。CRIB实验是通过~2h.^(16)O,n)^(17)F转移反应产生^(17)F次级束,经过CRIB分离提纯之后,利用该次级束轰击氢气靶。在氢气靶后布置了三套望远镜探测器系统,用以探测不同实验角度的反冲α粒子,在数据处理的过程中经过动力学重构后得到了~1h.^(17)F,α)^(14)O反应在质心系能区E_(c.m.)=2.7～3.4 MeV的反应截面。实验结果在3 MeV以上的高能区与前人的薄靶实验数据是一致的,在低能区本工作获得了新的实验数据,倾向于支持干涉相消的理论预言结果。
