Previous ITU Exhibitions Reflect Tremendous Changes in China's Telecom Industry——Houlin Zhao, Deputy Secretary-General of ITU

The long-awaited ITU Telecom World 2006 is to open in Hong Kong. It is no doubt that the hosting of this pageant in Hong Kong proves the praise and recognition of the rapid development of China's telecom industry as well as the favor and support to Hong Kong, a world-class trade metropolis. At this opportunity, I'd like to extend my warm congratulations to the event together with readers of China Telecommunications Trade.

An Improved Coupled Level Set and Continuous Moment-of-Fluid Method for Simulating Multiphase Flows with Phase Change

An improved algorithm for computing multiphase flows is presented in which the multimaterial Moment-of-Fluid(MOF)algorithm for multiphase flows,initially described by Li et al.(2015),is enhanced addressing existing MOF difficulties in computing solutions to problems in which surface tension forces are crucial for understanding salient flow mechanisms.The Continuous MOF(CMOF)method is motivated in this article.The CMOF reconstruction method inherently removes the"checkerboard instability"that persists when using the MOF method on surface tension driven multiphase(multimaterial)flows.The CMOF reconstruction algorithm is accelerated by coupling the CMOF method to the level set method and coupling the CMOF method to a decision tree machine learning(ML)algorithm.Multiphase flow examples are shown in the two-dimensional(2D),three-dimensional(3D)axisymmetric"RZ",and 3D coordinate systems.Examples include two material and three material multiphase flows:bubble formation,the impingement of a liquid jet on a gas bubble in a cryogenic fuel tank,freezing,and liquid lens dynamics.

Global glaciations and atmospheric change at ca.2.3 Ga

This paper compiles lithostratigraphic and geochronological data obtained for the Palaeoproterozoic glacial diamictite-bearing successions,and thereby provides insights into understanding the geological processes causing the Huronian Glaciation Event.The majority of evidence for appearances of this glaciation event can be related to the Kenorland supercontinent breakup,allied to significant atmospheric change,as well as blooms of biogeochemical oxygenic photosynthesis.In this paper,the Huronian Glaciation Event is constrained to have occurred synchronously during 2.29-2.25 Ga,accompanied by dramatic environmental changes characteristic of the Great Oxidation Event which includes the pre- 2.3 Ga hydrosphere oxidation and the post-2.3 Ga atmosphere oxygenation.

Streptozotocin induced Alzheimer's disease like changes and the underlying neural degeneration and regeneration mechanism

Alzheimer’s disease（AD）is a neurodegenerative disorder which is remarkably characterized by pathological hallmarks that include neurofibrillary tangles,neuronal loss extracellular senile plaques containing aggregated amyloid beta（Aβ）,and neurofibrillary tangles composed of the hyperphosphorylated form of the microtubule protein tau.It is the most common form of dementia which is characterized by severe neurodegenerative changes such as loss of neurons and synapses in brain（Kamat et al.,2014）.

CHINA'S VEGETATION/ECOSYSTEM RESPONSE TO GLOBAL CHANGE: RESEARCH PROGRESS & PROSPECTS

This paper presents the latest developments in the re search progress on mechanisms by which natural plants and crops respond to the doubled concentration of CO2 in the atmosphere, resultant climatic change and the modeling of vegetation and eco-systems in China. In addition, it points out that the future study on global change and terrestrial ecosystems should stress m(?)iti-disciplinary teamwork and inter-discipline penetration. Finally, the paper emphasizes 10 research realms in the field to be enhanced in the future.

CHANGES FOR CHINA'S FOREIGN TRADE GROWTH

In 1996,China began to set targets for quadrupling its per capitaaverage GNP for a better livelihood and socialist market economicsystem——a kind of mature opening economy in the Ninth Five-YearPlan period(1996-2000),aiming at comformity with the worldeconomy.For these purposes,it is essential to expand China’sopening to the outside for its foreign trade to boom and thus make fulluse of foreign and domestic markets for accelerating our economicdevelopment and upgrading development efficiency.In other words,China’s foreign trade development in the Ninth Five-Year Planperiod will greatly affect and control our economic growth andeconomic system reform.

Systematic Synthesis of Impacts of Climate Change on China's Crop Production System

Global climate change is real and already taking place. The most recent Fifth Assessment Report of the Intergov- ernmental Panel on Climate Change （IPCC AR5） stated that global land and ocean surface temperature increased by 0.85℃ over the period of 1880 to 2012 （IPCC Climate Change 2013）. China is among the most affected countries by global climate change.

A Witness's Account of Changes in Tibet's Human Rights Conditions

After riots that occurred on March 14, 2008 in Lhasa, Tibet, the China Central Television Station broadcast a documentary film titled Tibet＇s Past shot years ago by the Central Newsreel ＆ Documentary Film Studio about the miserable life of serfs under Tibet＇s feudal serf system before a democratic reform was carried out in the region. The documentary stunned many people. It helps people see through the reactionary and corrupt nature of the Dalai clique.
