Two calculation methods on the partition functions for diatomic molecules in plas- mas out of thermal equilibrium are reported. A Boltzmann distribution for the electronic, vi- brational and rotational quantum levels is assumed in the two calculation methods. The results obtained by two methods are displayed for four sorts of diatomic molecules, 02, N2, OH and NO, that are present in humid air plasmas. The calculation method of density for the electronically excited states is developed. Finally, a method to calculate the partition functions for simulating the non-normalized diatomic spectra is discussed.

Smoothed dissipative particle dynamics （SDPD） is a mesoscopic particle method that allows to select the level of resolution at which a fluid is simulated. The numerical integration of its equations of motion still suffers from the lack of numerical schemes satisfying all the desired properties such as energy conservation and stability. Similarities between SDPD and dissipative particle dynamics with energy （DPDE） con- servation, which is another coarse-grained model, enable adaptation of recent numerical schemes developed for DPDE to the SDPD setting. In this article, a Metropolis step in the integration of the fluctuation/dissipation part of SDPD is introduced to improve its stability.

Frontiers of History in China 2016年第4期11卷 510-531页

作者： David faure Xi He Department of History Chinese University ofHong Kong NT Hong Kong China

This essay examines two sets of reports in the Qing-dynasty Jiaqing and Daoguang periods （respectively 1796-1820 and 1821-45） in order to understand better the perceived reality of the Tiandihui. The first set, found anaong the papers of Jiangxi governor Xianfu （1809-14）, allows a comparison of a criminal gang that invoked the Tiandihui ceremony with one that did not. The second set includes the diary of Taihe county magistrate Xu Dihui （in office from 1824） that recorded various events which came to be reported to the senior officialdom as having been conducted by secret societies. By collating the incidents as reported in the diary and memorials to the emperor, the authors argue that the pressure of the administrative process was responsible for the ultimate acquiescence by the Hunan governor Han Wenqi （in office 1825-29） in the perception of an indisputable connection of the incidents with secret societies. Moreover, both sets of reports show that participants in secret-society ceremonies and officials who suppressed them knew that the acclaimed networking of the Tiandihui as implied in its folklore was very far from the reality.

Angiosperms sexual reproduction involves interactions between the two female gametes in the embryo sac and the two male gametes released by the pollen tube. The two synergids of the embryo sac express the FERONIA/SIRENE receptor-like kinase, which controls the discharge of the two sperm cells from the pollen tube. FER/SRN may respond to a ligand from the pollen tube. Alternatively, the interaction between FER/SRN and a ligand from the embryo sac may lead to a state of competence of the synergids allowing pollen tube discharge. Here, we report the new mutant scylla （syl） impaired in the control of pollen tube discharge. This mutant also produces autonomous endosperm development in ab- sence of fertilization--a trait associated with the FERTILIZATION INDEPENDENT SEED （FIS） mutant class. This led us to iden- tify autonomous endosperm in srn mutants and to demonstrate synergistic interactions between srn and the fis mutants. In addition, the fis mutants display defects in pollen tube discharge as in srn and syl mutants, confirming the interaction between the two pathways. Our findings suggest that pollen tube discharge is controlled by an interaction between the synergids expressing SRN/FER and the central cell expressing FIS genes.

The Trans-North China Belt （TNCB） is a Paleoproterozoic collisional orogen （ca. 1.9-1.8 Ga） responsible for the amalgamation of the North China Craton. Detailed field works in Liiliangshan, Hengshan, Wutaishan and Fuping massifs where the belt is well exposed, allow us to draw a new tectonic map and crustal-scale cross sections. The available petrologic, radiometric, geochronologic data are integrated in a geodynamic evolution scheme for this orogen. The Low Grade Mafic Unit （LGMU） is interpreted as an ophiolitic nappe rooted in a suture zone located in the western part of the Lüliangshan. This ophiolitic nappe overthrusts to the SE upon the Orthogneiss-Volcanites Unit （OVU） that consists of a bimodal volcanic-sedimentary series metamorphosed under amphibolite facies conditions intruded by calcalkaline orthogneiss. The OVU is a composite Neoarchean-Paleoproterozoic magmatic arc developed during two stages （ca. 2500 and 2100 Ma） upon a continental basement corresponding to the western extension of the Neoarchean Fuping massif The OVU overthrusts to the SE the Fuping massif along the Longquanguan shear zone. This stack of nappes, coeval with an amphibolite facies metamorphism, is dated at ca. 1880 Ma. Subsequently, the metamorphic series experienced a widespread migmatization at 1850 Ma and was intruded by post-orogenic plutons dated at 1800 Ma. The weakly to unmetamorphosed Hutuo Supergroup unconformably overlies the metamorphosed and ductilely deformed units （OVU and LGMU）, but it is also involved in a second tectonic phase developed in subsurface conditions. These structural features lead us to question the ca. 2090 Ma age attributed to the Hutuo supergroup. Moreover, in the Fuping massif several structural and magmatic lines of evidence argue for an earlier orogenic event at ca. 2100 Ma that we relate to an older west-directed subduction below the Fuping Block. The Taihangshan Fault might be the location of a possible suture zone between the Fuping Block and an ea
