Dear Editor,Transcription factors （TFs） are proteins that regulate the ex.ression of target genes by binding to specific cis-elements in pro-moter regions. Transcriptional regulators （TRs） a）so regulate the ex.ression of target genes; however, they operate indirectly via interaction with the basal transcription apparatus （e.g., TFs）, or by altering the accessibility of DNA to TFs via chromatin remodeling. Another type of regulatory proteins, protein kinases （PKs）,

Linear rolling guideways(LRGs) play an important role in precision engineering. In the pre-rolling region, the hysteretic friction force ex.rts great impacts on the positioning accuracy. Numerical and ex.erimental studies of the hysteresis of friction force are presented in this paper. A model, which is based on the stripe theory and the simplified theory of rolling contact, is built to describe the transient hysteresis of the friction force. Then, the model is modified by taking the anelasticity effect into consideration. Ex.erimentally, a linear motor direct-drive setup is utilized to measure the transient asymmetrical hysteresis of the friction force in the pre-rolling region of an LRG. The influences of the pre-rolling displacement and the dwelling time on the asymmetrical hysteresis of the friction force are studied. The numerical and ex.erimental results are well correlated, which shows good accuracy of the model. The transient asymmetrical hysteresis of friction force in the pre-rolling region of LRGs can thus be determined using the model.

Selected geological data on Early Cretaceous strata, structures, magmatic plutons and volcanic rocks from the Kunlun to Himalaya Mountains reveal a new view of the Early Cretaceous paleo-tectonics and the related geodynamic movement of the Tibetan Plateau. Two major paleo- oceans, the Mid-Tethys Ocean between the Qiangtang and Lhasa blocks, and the Neo-Tethys Ocean between the Lhasa and Himalayan blocks, ex.sted in the Tibetan region in the Early Cretaceous. The Himalayan Marginal and South Lhasa Seas formed in the southern and northern margins of the Neo- Tethys Ocean, the Central Tibet Sea and the Qiangtang Marginal Sea formed in the southern and northern margins of the Mid-Tethys Ocean, respectively. An arm of the sea ex.ended into the southwestern Tarim basin in the Early Cretaceous. Early Cretaceous intensive thrusting, magmatic emplacement and volcanic eruptions occurred in the central and northern Lhasa Block, while strike- slip formed along the Hoh-x.l and South Kunlun Faults in the northern Tibetan region. Early Cretaceous tectonics together with magmatic K20 geochemistry indicate an Early Cretaceous southward subduction of the Mid-Tethys Oceanic Plate along the Bangoin-Nujiang Suture which was thrust ~87 km southward during the Late Cretaceous-Early Cenozoic. No intensive thrust and magmatic emplacement occurred in the Early Cretaceous in the Himalayan and southern Lhasa Blocks, indicating that the spreading Neo-Tethys Oceanic Plate had not been subducted in the Early Cretaceous. To the north, terrestrial basins of red-beds formed in the Hoh-x.l, Kunlun, Qilian and the northeastern Tarim blocks in Early Cretaceous, and the Qiangtang Marginal Sea disappeared after the Qiangtang Block uplifted in the late Early Cretaceous.

Acute ozone is a model abiotic elicitor of ox.dative stress and a useful tool for understanding biochemical and molecular events during ox.dative signaling. Two Medicago truncatula accessions with contrasting responses to ozone were used to ex.mine translational regulation during ozone stress. In ozone-resistant JE154, significant reduction in ri- bosome loading was observed within one hour of ozone treatment, suggesting energy homeostasis as a vital factor for ox.dative stress management. Polysomal RNA-based ex.ression profiling with Affymetrix.arrays revealed ex.ensive changes in the translatomes of both accessions. Messenger RNAs with low GC content in their 5＇ and 3＇-UTRs were pref- erentially associated with polysomes during ox.dative stress. Genebins analysis revealed ex.ensive changes in various gene ontologies in both accessions. Ex.ensive changes in nicotinate and nicotinamide metabolism genes were corrobo- rated with increased levels of NAD＋ and NADH in JE154. The significantly lower NAD＋：NADH redox.status in JE154, in conjunction with higher ATP amounts, provided a cellular milieu conducive for overcoming ox.dative stress. Low levels of ATP, NADH, and suppression of antiox.dant defense responses, abet build-up of ozone-derived ROS and ultimately lead to ox.dative cell death in Jemalong.

Dex.ral-slip in the Nyainqentanglha region of Tibet resulted in oblique underthrusting and granite generation in the Early to Middle Miocene, but by the end of the epoch uplift and ex.ensional faulting dominated. The east-west dex.ral-slip Gangdise fault system merges eastward into the northeast-trending, southeast-dipping Nyainqentanglha thrust system that swings eastward farther north into the dex.ral-slip North Damx.ng shear zone and Jiali faults. These faults were took shape by the Early Miocene, and the large Nyainqentanglha granitic batholith formed along the thrust system in 18.3-11.0 Ma as the western block drove under the eastern one. The dex.ral-slip movement ended at -11 Ma and the batholith rose, as marked by gravitational shearing at 8.6-8.3 Ma, and a new fault system developed. Northwest-trending dex.ral-slip faults formed to the northwest of the raisen batholith, whereas the northeast-trending South Damx.ng thrust faults with some sinistral-slip formed to the southeast. The latter are replaced farther to the east by the west-northwest-trending Lhtinzhub thrust faults with dex.ral-slip. This relatively local uplift that left adjacent Eocene and Miocene deposits preserved was followed by a regional uplift and the initiation of a system of generally north-south grabens in the Late Miocene at -6.5 Ma. The regional uplift of the southern Tibetan Plateau thus appears to have occurred between 8.3 Ma and 6.5 Ma. The Gulu, Damx.ngYangbajain and Angan graben systems that pass east of the Nyainqentanglha Mountains are locally controlled by the earlier northeast-trending faults. These grabens dominate the subsequent tectonic movement and are still very active as northwest-trending dex.ral-slip faults northwest of the mountains. The Miocene is a time of great tectonic change that ushered in the modern tectonic regime.

With recent improvements in carbon nanotube separation methods, the accurate determination of residual metallic carbon nanotubes in a purified nanotube sample is important, particularly for those interested in using semiconducting single-walled carbon nanotubes （SWCNTs） in electronic device applications such as thin-film transistors （TFTs）. This work demonstrates that Raman microscopy mapping is a powerful characterization tool for quantifying residual metallic carbon nanotubes present in highly enriched semiconducting nanotube networks. Raman mapping correlates well with absorption spectroscopy, yet it provides greater differentiation in purity. Electrical data from TFTs with channel lengths of 2.5 and 5μ m demonstrate the utility of the method. By comparing samples with nominal purities of 99.0% and 99.8%, a clear differentiation can be made when evaluating the current on/off ratio as a function of channel length, and thus the Raman mapping method provides a means to guide device fabrication by correlating SWCNT network density and purity with TFT channel scaling.
