In this talk we study the homotopy type of the (double) suspension of an orientable, closed, connected 4-manifold M, whose integral homology can have 2-torsion. Moreover, the decomposition results are...
Here, the effects of the ethylene-releasing compound, ethephon, and the ethylene precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), on ionic currents across plasma membranes and on the cytosolic ...
MENLO PARK, Calif.—March 12, 2014—On January 13, 2014, the William E. Gordon radio telescope in Arecibo, Puerto Rico sustained damage following a 6.4 magnitude earthquake that was centered 37 miles no...
Arecibo Observatory main suspension cable repaired following earthquake     Arecibo Observatory  earthquake       font style='font-size:12px;'> 2014/3/20
On Jan. 13, 2014, the William E. Gordon radio telescope in Arecibo, Puerto Rico, sustained damage following a 6.4 magnitude earthquake that was centered 37 miles northwest of Arecibo. Today, the obser...
Abstract: In this note we show that for any Hamiltonian defined on a symplectic 4-manifold M and any point p in M, there exists a C2-close Hamiltonian whose regular energy surface through p is either ...
Abstract: In this paper we compute the coefficients of the heat kernel asymptotic expansion for Laplace operators acting on scalar functions defined on the so called spherical suspension (or Riemann c...
Coupling high quality, suspended atomic membranes to specialized electrodes enables investigation of many novel phenomena, such as spin or Cooper pair transport in these two dimensional systems. Howe...
We study numerically the in uence of density and strain rate on the di usion and mobility of a single tagged particle in a sheared colloidal suspension. We determine independently the time-dependent v...
Lie-Hopf algebras and loop homology of suspension spaces     Lie-Hopf algebras  loop homology  suspension spaces       font style='font-size:12px;'> 2010/11/18
For an arbitrary topological space $X$, the loop space homology $H_*(\Omega\Sigma X; \mathbb{Z})$ is a Hopf algebra. We introduce a new homotopy invariant of a topological space $X$ that takes values...
A laboratory experiment was conducted to examine the temporal dynamics of the particle size distribution (PSD) and associated optical variability caused by viral infection of marine heterotrophic bac...
初步建立茶条槭(Acer ginnala)细胞悬浮培养体系: 以茶条槭子叶为外植体, 接种于WPM培养基中, 对茶条槭愈伤组织进行诱导和继代培养。悬浮培养中, 每代增长指数达到11.6, 没食子酸含量达到1.518%。通过对比NT、IS、WPM、B5和MS培养基所含成分对茶条槭愈伤组织悬浮培养的影响, 综合考虑悬浮细胞的生长速率和有效成分的含量, 确定WPM为基本培养基。WPM培养基大量元素的浓度...
期刊信息 篇名 Restoration and amplification of image through moving randomly suspension particles using photorefractive two-wave mixing 语种 英文 撰写或编译 撰写 作者 Zhang Guangyin,Xu Jingjun,Liu Simin,Men Liqiu,Liu ...
A novel N-succinylchitosan-graft-polyacrylamide/attapulgite composite hydrogel was prepared by using N-succinylchitosan, acrylamide and attapulgite through inverse suspension polymerization. The resul...
A storm-induced suspension interflow (a kind of turbidity current) in subtropical deep (113-m maximum depth) Feitsui Reservoir, Taiwan, was traced and simulated for both water quantity and quality con...
We placed individual Elliptio complanata in aerated suspensions of conidia (asexual spores) of aquatic hyphomycetes (Fungi). Mussels actively ingested conidia at an initial rate of over 20,000 h-1. Th...
