It is with deep respect that we announce the passing of Professor Michael Newton Marsh. He spent much last 50 years working on small intestine immunopathology, including electron microscopy and tissue structure. was his determination, hard work ability to apply science clinical practice resulted in milestones not only coeliac disease histology but also pioneering recirculating thoracic duct lym...

Ozone pollution in China has become increasingly severe recent years. Considering the damage that extreme ozone may cause and fact occurrence of among different locations be related, this paper uses hourly concentration data from national monitoring stations to investigate co-movement Beijing-Tianjin-Hebei (BTH) Region. The dependence analysis is adopted assess such co-movements between cities....

The Linac Coherent Light Source (LCLS), the world’s first hard xray free electron laser is under construction at the Stanford Linear Accelerator Center and is expected to be completed in 2009. LCLS will deliver unprecedented bright and short x-ray laser pulses that shall enable frontier new science research in biology, nanomaterials and non-crystalline imaging. Over 400 m of LCLS tunnel have be...

Air pollution has become a great challenge to achieving sustainable development. Among the pollutants, aerosols significantly affect human health and play an important role in global climate change. The concentration of ambient air is influenced strongly by regional transport pollutants their precursors may vary considerably under different meteorological conditions years. This inter-annual var...

With the continued social and economic development of northern China, landscape fragmentation has placed increasing pressure on the ecological system of the Beijing-Tianjin-Hebei (BTH) region. To maintain the integrity of ecological processes under the influence of human activities, we must maintain effective connections between habitats and limit the impact of ecological isolation. In this pap...

Urban expansion has significant effects on forest loss and fragmentation. Previous studies mostly focused on how the amount of developed land affected forest loss and fragmentation, but neglected the impacts of its spatial pattern. This paper examines the effects of both the amount and spatial pattern of urban expansion on forest loss and fragmentation. We conducted a comparison study in the si...

Identifying genetic variants that regulate quantitative traits, or QTLs, is the primary focus of the field of statistical genetics. Most current methods are limited to identifying mean effects, or associations between genotype and the mean value of a quantitative trait. It is possible, however, that a genetic variant may affect the variance of the quantitative trait in lieu of, or in addition t...

We isolated a dominant gain-of-function Arabidopsis mutant, accelerated cell death 6 (acd6), with elevated defenses, patches of dead and enlarged cells, reduced stature, and increased resistance to Pseudomonas syringae. The acd6-conferred phenotypes are suppressed by removing a key signaling molecule, salicylic acid (SA), by using the nahG transgene, which encodes SA hydroxylase. This suppressi...
