Dear Editor,The ultraviolet （UV）-B wavelength （280-315 nm） is an indispensable component of the sunlight that reaches the earth＇s surface. Long-wavelength and Iow-fluence UV-B specifically induces plant photomorphogenesis, which is characterized by inhibition of hypo- cotyl elongation, promotion of anthocyanin accumulation, and eventually tolerance against UV-B stress （Jenkins, 2009）.

To investigate the circuit-level neural mechanisms of behavior, simultaneous imaging of neuronal activity in multiple cortical and subcortical regions is highly desired. Miniature head-mounted microscopes offer the capability of calcium imaging in freely behaving animals. However, implanting multiple microscopes on a mouse brain remains challenging due to space constraints and the cumbersome weight of the ***, we present TINIscope, a Tightly Integrated Neuronal Imaging microscope optimized for electronic and opto-mechanical design. With its compact and lightweight design of 0.43 g, TINIscope enables unprecedented simultaneous imaging of behavior-relevant activity in up to four brain regions in ***-of-concept experiments with TINIscope recorded over 1000 neurons in four hippocampal subregions and revealed concurrent activity patterns spanning across these regions. Moreover, we explored potential multi-modal experimental designs by integrating additional modules for optogenetics, electrical stimulation or local field potential recordings. Overall, TINIscope represents a timely and indispensable tool for studying the brain-wide interregional coordination that underlies unrestrained behaviors.

In this paper, we designed and evaluated a duplex detection strategy for micro RNAs（mi RNAs） using universal probe-based target-triggered double hybridization and fluorescent microsphere-based assay system（x MAP array）. In the absence of target mi RNA, reporter DNA cannot hybridize stably with the immobilized capture DNA due to its low melting temperature. Only after adding target mi RNA, can reporter probe hybridize with capture probe to form a stable three-component complex. This targettriggered stable hybridization makes this method possible for highly selective and sensitive detection of multiple mi RNAs. We exemplified a quantitative detection of duplex mi RNAs with a limit of detection of40 p M. The x MAP array platform holds the potential of extending this approach to simultaneous detection of up to 100 mi RNA targets. Considering the simplicity, rapidity and multiplexing, this work promised a potential detection of multiple mi RNA biomarkers for early disease diagnosis and prognosis.

Let G be a graph with vertex set V(G) and edge set E(G). A labeling f : V(G) →Z2 induces an edge labeling f*: E(G) → Z2 defined by f*(xy) = f(x) + f(y), for each edge xy ∈ E(G). For i ∈ Z2, let vf(i) = |{v ∈ V(G) : f(v) = i}| and ef(i) = |{e ∈ E(G) : f*(e) =i}|. A labeling f of a graph G is said to be friendly if |vf(0)- vf(1)| ≤ 1. The friendly index set of the graph G, denoted FI(G), is defined as {|ef(0)- ef(1)|: the vertex labeling f is friendly}. This is a generalization of graph cordiality. We investigate the friendly index sets of cyclic silicates CS(n, m).

Tropical disturbances over the South China Sea (SCS) during the period of 1997-2006 are analyzed using the Tropical Storm and Hurricane WX products. A total of 158 tropical disturbances were formed over the SCS from 1997 to 2006, with 54 de-veloping tropical disturbances which developed into tropical depressions and 104 non-developing tropical disturbances which never developed into tropical depressions. The development rate of tropical disturbances into tropical depressions was 34.18% in these ten years. During the period of this study, total annual numbers of tropical disturbances and developing tropical disturbances over the SCS had significant decreasing trends; however, the development rate of tropical disturbances had an insignificant increasing trend.
