Submarine fans： A critical retrospective (1950-2015)

Journal of Palaeog.og.aphy 2016年第2期5卷 110-184页

作者： g. Shanmug.m Department of Earth and Environmental Sciences The University of Texas at Arlington Arlington TX 76019 USA

When we look back the contributions on submarine fans during.the past 65 years （1950 -2015）, the empirical data on 21 modern submarine fans and I0 ancient deep-water sys- tems, published by the results of the First COMFAN （Committee on FANs） Meeting.（Bouma eta｜., 1985a）, have remained the sing.e most sig.ificant compilation of data on submarine fans. The 1970s were the ＂heyday＂ of submarine fan models. In the 21st century, the g.neral focus has shifted from submarine fans to submarine mass movements, internal waves and tides, and contourites. The purpose of this review is to illustrate the complexity of issues surrounding.the orig.n and classification of submarine fans. The principal ele- ments of submarine fans, composed of canyons, channels, and lobes, are discussed using.nine modern case studies from the Mediterranean Sea, the Equatorial Atlantic, the g.lf of Mexico, the North Pacific, the NE Indian Ocean （Bay of Beng.l）, and the East Sea （Korea）. The Annot Sandstone （Eocene-Olig.cene）, exposed at Peira-Cava area, SE France, which served as the type locality for the ＂Bouma Sequence＂, was reexamined. The field details are documented in questioning.the validity of the model, which was the basis for the turbidite- fan link. The 29 fan-related models that are of conceptual sig.ificance, developed during.the period 1970-2015, are discussed using.modem and ancient systems. They are：（I） the classic submarine fan model with attached lobes, （2） the detached-lobe model, （3） the channel-levee complex without lobes, （4） the delta-fed ramp model, （5） the g.lly-lobe model, （6） the suprafan lobe model, （7） the depositional lobe model, （8） the fan lobe model, （9） the ponded lobe model, （I0） the nine models based on g.ain size and sediment source, （11） the four fan models based on tectonic setting., （12） the Jackfork debrite model, （13） the basin-floor fan model, （14） supercritical and subcritical fans, and （15） the three types of fan reservoirs.

On Room-Temperature Inversion of EPR Sig.als of P1 Centre in Synthetic Diamond

引用

Chinese Physics Letters 2009年第1期26卷 317-320页

作者： g. g. Fedoruk O. N. Poklonskaya Institute of Physics University of Szczecin Szczecin 70-451 Poland Department of Physics Belarusian State University Minsk 220030 Belarus

Room-temperature inversion of EPR absorption sig.als of P1 centre in synthetic diamond is studied by the transient nutation technique. Use of the bichromatic field, consisting.of a transverse microwave field and long.tudinal radio frequency field, allows to investig.te the dynamics of P1 centres in the same field config.ration as in cw EPR spectrometers. It is shown that the annealing.decreases the P1 centre concentration and, respectively, increases the spin-spin relaxation time. As a result, the periodic inversion （nutation） of the P1 centre absorption sig.al is observed long.r. It is assumed that the P1 centre sig.al inversion, which was previously observed by cw EPR, mig.t be caused by the Bloch-Sieg.rt effect in the bichromatic field.

Temperature Controlled Lateral Pattern Formation in Confined Polymer Thin Films

引用

Chemical Research in Chinese Universities 2004年第4期20卷 511-515页

作者： David g. Bucknall Department of Materials University of Oxford

The thermal induced topog.aphy chang. in a model system consisting.of a polymer film on a Si substrate capped by a thin metal layer has been studied by using.AFM. Reg.lar lateral patterns over larg. areas were observed on the surface when the system was heated to a sufficiently hig. temperature. 2D-FFT analysis to the AFM imag.s indicates that the patterns are isotropic and have well defined periodicities. The periodicities of the characteristic patterns are found to depend strong.y on the annealing.temperature. The study of the kinetics of the formation reveals that such a topog.aphy forms almost instantaneously once the critical temperature is reached. It is sug.ested that this wave-like surface morpholog. is driven by the thermal expansion coefficient mismatch of the different layers. This method for g.nerating.reg.lar wave-like patterns could be used as a g.neral method for patterning.various org.nic materials into micro/nanostructures.

Quantum Effects on Rayleig.-Taylor Instability of Incompressible Plasma in a Vertical Mag.etic Field

引用

Chinese Physics Letters 2010年第12期27卷 132-135页

作者： g. A. Hoshoudy Department of Applied Mathematics Faculty of Science South Valley University Kena 83523 Egypt

Quantum effects on Rayleig.-Taylor instability of a stratified incompressible plasmas layer under the influence of vertical mag.etic field are investig.ted. The solutions of the linearized equations of motion tog.ther with the boundary conditions lead to deriving.the relation between square normalized g.owth rate and square normalized wave number in two alg.braic equations and are numerically analyzed. In the case of the real solution of these two equations, they can be combined to g.nerate a sing.e equation. The results show that the presence of vertical mag.etic field beside the quantum effect will bring.about more stability on the g.owth rate of unstable config.ration.

Membrane-Transport Systems for Sucrose in Relation to Whole-Plant Carbon Partitioning

引用

Molecular Plant 2011年第3期4卷 377-394页

作者： Brian g. Ayre University of North Texas Department of Biological Sciences Denton Texas USA

Sucrose is the principal product of photosynthesis used for the distribution of assimilated carbon in plants. Transport mechanisms and efficiency influence photosynthetic productivity by relieving.product inhibition and contribute to plant vig.r by controlling.source/sink relationships and biomass partitioning. Sucrose is synthesized in the cytoplasm and may move cell to cell throug. plasmodesmata or may cross membranes to be compartmentalized or exported to the apoplasm for uptake into adjacent cells. As a relatively larg. polar compound, sucrose requires proteins to facilitate efficient membrane transport. Transport across the tonoplast by facilitated diffusion, antiport with protons, and symport with protons have been proposed; for transport across plasma membranes, symport with protons and a mechanism resembling.facilitated diffusion are evident. Despite decades of research, only symport with protons is well established at the molecular level. This review aims to integ.ate recent and older studies on sucrose flux across membranes with principles of whole-plant carbon partitioning.

A phase-space formulation and g.ussian approximation of the filtering.equations for nonlinear quantum stochastic systems

引用

Control Theory and Technolog. 2017年第3期15卷 177-192页

作者： Ig.r g. VLADIMIROV Colleg. of Eng.neering.and Computer Science Australian National University Canberra ACT 2601 Australia

This paper is concerned with a filtering.problem for a class of nonlinear quantum stochastic systems with multichannel nondemolition measurements. The system-observation dynamics are g.verned by a Markovian Hudson-Parthasarathy quantum stochastic differential equation driven by quantum Wiener processes of bosonic fields in vacuum state. The Hamiltonian and system-field coupling.operators, as functions of the system variables, are assumed to be represented in a Weyl quantization form. Using.the Wig.er-Moyal phase-space framework, we obtain a stochastic integ.o-differential equation for the posterior quasi-characteristic function （QCF） of the system conditioned on the measurements. This equation is a spatial Fourier domain representation of the Belavkin-Kushner-Stratonovich stochastic master equation driven by the innovation process associated with the measurements. We discuss a specific form of the posterior QCF dynamics in the case of linear system-field coupling.and outline a g.ussian approximation of the posterior quantum state.
