We propose to create a secondary beam of neutral kaons in Hall D at Jefferson Lab to be used with the GlueX experimental setup for strange hadron spectroscopy. A flux on the order of 3 × 104KL/s will allow a broad range of measurements to be made by improving the statistics of previous data obtained on hydrogen targets by three orders of magnitude. Use of a deuteron target will provide first measurements on the neutron which is terra incognita. The experiment will measure both differential cross sections and self-analyzed polarizations of the produced Λ, Σ, Ξ, and Ω hyperons using the GlueX detector at the Jefferson Lab Hall D. The measurements will span cm. cos θ from -0.95 to 0.95 in the cm. range above W = 1490 MeV and up to 3500 MeV. These new GlueX data will greatly constrain partial-wave analyses and reduce model-dependent uncertainties in the extraction of strange resonance properties (including pole positions), and provide a new benchmark for comparisons with QCD-inspired models and lattice QCD calculations. The proposed facility will also have an impact in the strange meson sector by providing measurements of the final-state Kπ system from threshold up to 2 GeV invariant mass to establish and improve on the pole positions and widths of all K∗(Kπ) P-wave states as well as for the S-wave scalar meson κ(800).

China will soon be under the pressure of controlling the emissions of CO2 and various air pollutants simultaneously. Power sector as the largest contributor is the key sector to fulfill this task, which makes a power sector model with consideration of multiple air emissions control in great need for supporting policy making. This study built a multi- period optimization model for China s power sector with considerations of SO2, NOX and CO2 emission control and accounting of Hg emissions, based on six regional power grids with growing inter-connections. A case study of technology development and emission trends in China s power sector between 2010 and 2030 follows, using regional technology and fuel data in 2010, and advices for further model development come last.

Physical Review A 2013年第4期87卷 043631-043631页

作者： Fu-quan Dou Li-bin Fu Jie Liu College of Physics and Electronic Engineering Northwest Normal University Lanzhou 730070 China School of Physics Beijing Institute of Technology Beijing 100081 China National Laboratory of Science and Technology on Computation Physics Institute of Applied Physics and Computational Mathematics Beijing 100088 China Key Laboratory of High Energy Density Physics Simulation Center for Applied Physics and Technology Peking University Beijing 100084 China

We investigate the creation of stable homonuclear and heteronuclear N-body polymer molecules from ultracold atoms via a generalized stimulated Raman adiabatic passage scheme. The atom-molecule dark-state solutions for the system are obtained and are found to satisfy universal algebraic equations. We discuss the linear instability and the adiabatic fidelity of the dark state. We also explore the effects of the interparticle interactions, the atomic number of the polymer, and external field parameters on the conversion process.

To describe the lateral jet force model accurately, an identification method based on FCM-SVM is provided. The experimental data is clustered with this method to gain the best partition and separating hyperplanes. Different classes are identified respectively using maximum-likelihood estimation method. The test data is classified through separating hyperplanes. The output of test data can be forecasted according to the expression of corresponding class. Result shows that the precision is increased by 31% compared with traditional identification model. The identification result based on FCM-SVM can supply support for the design of control system. © 2012 Springer-Verlag London Limited.

A radiation model of millimeter wave antenna is established in this paper. The electromagnetic field distribution on the seeker antenna is calculated in MMWSS based on PO method. According the numerical results, when target is in the near-field of antenna, the characteristic of echo amplitude has an obvious effect of multi-scattering points effect. © 2012 IEEE.

In this paper, the physical optical (PO) method is employed to calculate the electromagnetic field distribution on the seeker antenna when the missile approaches the target. Compared with the result calculated in the millimeter wave simulation system (MMWSS), it can be equivalent to one or more scattering points when the target is located in the far-field of antenna.

In this paper, we examine a resonant capacitor current feedback (RCCF) self-oscillating resonant inverter from nonlinear point of view. By adopting a four-stage equivalent model, we derive the soft-switching dead time from time-domain for the series resonant capacitor linked parallel load circuit. Importantly, we propose a nonlinear model for the current feedback and gate-drive circuit. Based on analyzing the switching transition interval of this model, the determination of feedback parameters is inferred with given input power and resonant elements. Experimental results have been obtained for a RCCF self-oscillating inverter operating at 3 MHz and 300 V bus voltage. © 2012 IEEE.
