The proton resonant properties in 18Ne, which determine the reaction rate of the key stellar 14O(α,p)17F reaction, have been studied by using a technique of proton resonant elastic scattering of 17F+p. A 4.22 MeV/nucleon 17F radioactive ion (RI) beam was produced via a projectile-fragmentation reaction, and separated by a Radioactive Ion Beam Line in Lanzhou (RIBLL). By bombarding a thick (CH2)n target, the energy spectra of the recoiled protons were measured by two ΔE-E silicon telescopes at the center-of-mass scattering angles of θc.m.≈175°±5°, θc.m.≈152°±8°, respectively. Several proton resonances in 18Ne were ob served clearly. A further R-matrix analysis of the experimental data is under way to determine the resonant parameters. The present work reports the preliminary results briefly.

Abstract: The Wutai Complex associated with the adjacent Fuping and hengshan Complexes represents the best and classical cross-section in the middle segment of the Trans-North China Orogen, generally divided into Eastern and Western Blocks. Unconformably overlying the Wutai and Fuping Complexes is the Hutuo Group considered as the youngest lithostratigraphic unit in the region and important both for interpreting Precambrian history as well as the overall evolution of the Trans-North China Orogen. Lack of knowledge about provenance of the sedimentary rocks in this group has hindered understanding of the depositional environments and tectonic significance. LA-ICP-MS was applied to obtain U-Pb zircon ages for the granitic pebbles, the lowest lithostratigraphic rock of the Hutuo Group, which, combined with previous lithostratigraphic, geochronological, structural and metamorphic data, provides new constraints on the sedimentary provenance and tectonic evolution of the region. The sequence of the Hutuo Group ranges upward from lower basal conglomerates and volcaniclastic rocks (Doucun Subgroup), through clastic sediments, slates, dolomites and marbles (Dongye Subgroup), to sandstones and conglomerates at the top (Guojiazhai Subgroup). Zircons from granitic pebbles preserved in the Doucun Subgroup basal conglomerates give weighted mean 207 Pb/ 206 Pb ages between 2517 Ma and 2566 Ma, which are the same as those for the late Archean Wutai Granitoids, indicating that the pebbles were derived from the Wutai granitic intrusions (2566-2515 Ma). Based on the new data and previous studies, combined with an igneous zircon crystallization age of 2087±9 Ma obtained for volcanics in the Hutuo Group, the Hutuo Group was deposited in a subduction-related retro-arc foreland basin environment that developed behind the Wutai arc during the eastward-directed subduction of the Western Block beneath the western margin of the Eastern Block. This basin underwent long-lived sedimentation and f

What Happened in the Trans-North China Orogen in the Period 2560-1850 Ma?

Abstract: The Trans-North China Orogen (TNCO) was a Paleoproterozic continent-continent collisional belt along which the Eastern and Western Blocks amalgamated to form a coherent North China Craton (NCC). Recent geological, structural, geochemical and isotopic data show that the orogen was a continental margin or Japan-type arc along the western margin of the Eastern Block, which was separated from the Western Block by an old ocean, with eastward-directed subduction of the oceanic lithosphere beneath the western margin of the Eastern Block. At 2550-2520 Ma, the deep subduction caused partial melting of the medium-lower crust, producing copious granitoid magma that was intruded into the upper levels of the crust to form granitoid plutons in the low- to medium-grade granite-greenstone terranes. At 2530-2520 Ma, subduction of the oceanic lithosphere caused partial melting of the mantle wedge, which led to underplating of mafic magma in the lower crust and widespread mafic and minor felsic volcanism in the arc, forming part of the greenstone assemblages. Extension driven by widespread mafic to felsic volcanism led to the development of back-arc and/or intra-arc basins in the orogen. At 2520-2475 Ma, the subduction caused further partial melting of the lower crust to form large amounts of tonalitic-trondhjemitic-granodioritic (TTG) magmatism. At this time following further extension of back-arc basins, episodic granitoid magmatism occurred, resulting in the emplacement of 2360 Ma, ∼2250 Ma 2110–21760 Ma and ∼2050 Ma granites in the orogen. Contemporary volcano-sedimentary rocks developed in the back-arc or intra-arc basins. At 2150-1920 Ma, the orogen underwent several extensional events, possibly due to subduction of an oceanic ridge, leading to emplacement of mafic dykes that were subsequently metamorphosed to amphibolites and medium- to high-pressure mafic granulites. At 1880-1820 Ma, the ocean between the Eastern and Western Blocks was completely consumed by subducti

With the increase of the networking functions of the mobile handheld devices, today there is a strong need for receiving multimedia through mobile handheld devices. However, the current streaming technologies cannot well satisfy the users' need due to the large network bandwidth requirement and high price. And the infrastructure of broadcasting oriented for a mobile handheld device, such as DVB-H, are not yet popular in the daily life. Based on these considerations, a new multimedia and information service gateway is proposed, where novel multimedia and information services can be well provided to users with mobile devices. The gateway can connect DVB network, Internet, IPTV etc. media and content provisioning networks with the local area networks such as WLAN and LAN, as well as 3G cellular networks and WiMax which provide access to mobile and portable devices. The gateway aggregates media and Internet information and then distributes them via different access networks to mobile users. The most important feature of the gateway is that it has introduced the idea of the autonomic communications to solve the key problems for providing multimedia services like the video quality and the heterogeneity of mobile devices. Two control loops are designed in the gateway, based on which the autonomic source media transcoding and the dual-driven autonomic channel transcoding techniques are realized. hence, the gateway system can adapt itself to the varying environments and can therefore provide better multimedia services to users. In general, the gateway can realize the following functions: sending multimedia to individual mobile devices with suitable format, size, and resolution. multicasting multimedia to a group of mobile devices. broadcasting multimedia to the mobile devices in the local area. providing various information services to users through push or pull. Especially, the gateway has the following three autonomic features: autonomic user management: i.e., it can obtai

Providing multimedia and information services to mobile devices is one of the most important services in the future networks. However, problems like the heterogeneity of the mobile devices, the quality of the received video in the wireless environment, as well as the cost for the users to enjoy the multimedia services etc. have not been well solved and therefore the need of mobile users cannot be well satisfied. This paper proposes a new multimedia and information service provisioning solution through introducing an autonomic multimedia. and information service gateway, where novel multimedia and, information services can be provided to users by combining DVB, Internet and WLAN networks. Especially, the gateway has introduced two control loops, which can adapt itself to the varying environments and can therefore provide better multimedia services to users.
