The sediment record of the loess-paleosol sequence in the Chinese loess Plateau reveals a strong relationship between grain size fluctuations and glacial-interglacial cycles documented by marine oxygen isotope variations. However,on tectonic time scales,differences between the loess-paleosol grain size record and the marine oxygen isotope record can be *** results from the Baishui,Jingchuan and lingtai sections show that the grain size of eolian loess,superimposed on a coarsening trend, has two abrupt shifts at about 2.55 and 1.25 Ma,which are followed by significantly damped fluctuations in grain size. This is different from the global oxygen isotope record which demonstrates higher amplitude variations since the late Pliocene-early Pleistocene and lacks analogs of the abrupt *** propose that the progressive uplift of the Tibetan plateau may have forced the regional environmental system across two thresholds at the late Pliocene-early Pleistocene and the middle Pleistocene, respectively,inducing two pulses of climatic and environmental changes over north-western China which are superimposed on the global cooling trend and orbital climate *** TERMs:3344 Meteorology and Atmospheric Dynamics:Paleoctimatology;9320 Information Related to Geographic Region:Asia;9604 Information Related to Geologic Time:Cenozoic

The loess-paleosol-red clay sequence in the Chinese loess Plateau has attracted attention for its potential in recording late Cenozoic climatic changes over northern China,although the details of the climatic implications of the proxies(for example,magnetic susceptibility) and the reconstructed summer monsoon changes remain *** we report on a new section from Baishui,in Gansu province and compare it with the lingtai and Jingchuan *** correlating the magnetic susceptibility from these sections,we show that there is a clear systematic decrease of the magnetic susceptibility in the red clay deposits from the southeast(lingtai section) to the northwest(Baishui section).This result suggests that the climatic parameters(probably precipitation) had a decreasing northwestward gradient during the red clay *** climatic pattern is similar to the present condition,implying that the influence of the East Asian summer monsoon on the Chinese loess Plateau has persisted from at least 6 Ma.

There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BEsⅢ and B factories, and the observation of an intriguing proton-antiproton threshold enhancement and the possibly related X(1835) meson state at BEsⅢ, as well as the threshold measurements of charm mesons and charm baryons. We present a detailed survey of the important topics in tau-charm physics and hadron physics that can be further explored at BEsⅢ during the remaining operation period of BEPCⅡ. This survey will help in the optimization of the data-taking plan over the coming years, and provides physics motivation for the possible upgrade of BEPCⅡ to higher luminosity.
