Non-blocking 2×2 switching unit based on nested silicon microring resonators with high extinction ratios and low crosstalks

In this paper, we propose and demonstrate a 2 × 2 optical Benes switching unit based on two nested silicon microring resonators （MRRs） monolithically integrated on a silicononinsulator （SOI） wafer. High extinction ratios （ERs） of about 44.7/38.0 dB and low crosstalk values of about -37.5/-45.2 dB at cross/bar states are obtained with the fabricated device. The operation principle is theoretically studied and the switching function is verified by system demonstration experiments with 10 and 12.5 Gb/s nonreturntozero （NRZ） signals. The switching speed on the order of gigahertz based on free carrier effect in silicon is also experimentally demonstrated.

Identification and field evaluation of the sex pheromone of an invasive pest,the fall webworm <Emphasis Type="Italic">Hyphantria cunea</Emphasis> in China

Pheromone gland extracts of the fall webworm, Hyphantria cunea （Lepidoptera： Arctiidae） were analyzed by gas chromatography （GC） and gas chromatography-mass spectrometry （GC-MS）. Based on comparison of retention times and mass spectra of synthetic standards, four compounds were identified as （9Z,12Z）-octadecadienal, （9Z,12Z,15Z）-octadecatrienal, （3Z,6Z,9S, 10R）-9,10-epoxy-3,6-heneico- sadiene and （3Z,6Z,9S,10R）-9,10-epoxy-1,3,6-heneicosatriene with a ratio of 2：33.6：58.4：6. Trapping tests showed that quaternary blend of these compounds was highly attractive to male H. cunea. Unitraps baited with the quaternary blend loading of 200-300 μg on a gray rubber septum were very effective for monitoring H. cunea populations.     

Trace determination of zirconium using anodic adsorptive voltammetry at a carbon paste electrode modified with multi-walled carbon nanotubes

A carbon paste electrode modified with multi-walled carbon nanotubes （MWCNT） was prepared and the determination of ultra trace amount of zirconium based on the anodic adsorptive voltammetry of the zirconium-calcium-alizarin red S mix-polynuclear complex is described in this paper for the first time. The results showed that the sensitivity and the selectivity of the method are excellent. The second derivative linear scan voltammograms of the complex were recorded by polarographic analyzer from 200 to 1200 mV （vs. SCE） and it was found that the complex can be adsorbed on the surface of the electrode, yielding a peak at about 840 mV, corresponding to the oxidation of ARS in the complex. The peak current increases linearly with Zr （IV） concentration in the range of 6.0×10^-12--6.0×10^-11 mol. L^-1 （accumulation time 120 s）, 6.0×10^-11--2.0×10^-9 mol. L-1 （accumulation time 90 s） and 2.0×10^-9--1.0×10^-7 mol. L^-1 （accumulation time 60 s） and the detection limit （S/N = 3） is 2.0×10^-12 mol. L^-1 （accumulation time 180 s）. The procedure has been successfully applied to the determination of zirconium in the ore samples.     

The uptake of ethyl iodide on black carbon surface

The importance of the iodine chemistry in the atmosphere has been demonstrated by recent obserations. The uptake of ethyl iodine on black carbon surface was inestigated at 298 K for the first time. Degussa FW2 （an amorphous black carbon comprising medium oxides） was used as black carbon sample. Black carbon surface was found to be deactiated in reaction with C2H51, and the uptake coefficient （r） was dependent on the time of exposure. The alue of （2.3±0.9）×10^-2 was determined for the initial uptake coefficient （No）. The result suggests that the heterogeneous loss of C2H51 on carbonaceous aerosols may be important under the atmospheric conditions.     

Sandwich-Boomerang attack on reduced round CLEFIA

CLEFIA （ named after the French word ＂Clef＂ meaning ＂Key＂ ） is an efficient, highly secure block cipher proposed by SONY Corporation in the 14th International Workshop on Fast Software En- cryption （ FSE-2007 ） and many cryptanalyses have been used to analyze it. According to the proper- ty of CLEFIA, a new technique Sandwich-Boomerang cryptanalysis is used on it. An 8-round Sand- wich-Boomerang distinguisher of CLEFIA is constructed using the best differential characteristic of CLEFIA. And then, based on the distinguisher, an attack against 10-round CLEFIA is proposed. The number of chosen plaintexts required is 2^119（or 2^120） and the time complexity is 2^120（or 2^121）. Compared with a 7-round impossible Boomerang distinguisher presented by Choy in the 4th Interna- tional Workshop on Security （IWSEC-2009） , the differential characteristics used in the attack are all the best ones, so it is believed that the attack is the best result that the Boomerang attacks can get on CLEFIA at present.

Excitatory effect of histamine on neuronal activity of rat cerebellar fastigial nucleus Jn vitro

The cerebellar fastigial nucleus （FN） holds an important role in motor control and body balance. Previous studies have revealed that the nucleus is innervated by direct hypothalamocerebellar hletaminergic fibers. However, the functional role of histaminergic projection in cerebellar FN has never been established. In this study, we investigated the effect of histamine on neuronal firing of cerebellar FN by using slice preparations. Sixty-five FN cells were recorded from 47 cerebellar slices, and a vast majority of the cells responded to histamine stimulation with an excitatory response （58/65, 89.2%）. Perfusing slices with low-Ca^2＋/high-Mg^2＋ medium did not block the histamine-induced excitation （n=10）, supporting a direct postsynaptic action of histamine on the cells. Furthermore, the excitatory effect of histamine on FN neurons was not blocked by selective histamine H1 receptor antagonist triprolidine （n=15） or chlorpheniramine （n=10）, but was effectively suppressed by ranitidine （n=15）, a highly selective histamine H2 receptor antagonist. On the other hand, highly selective histamine H2 receptor agonist dimaprit （n=20） instead of histamine HI receptor agonist 2-pyridylethylamine （n=16） mimicked the excitatory effect of histamine on FN neurons. The dimaprit-induced FN neuronal excitation was effectively antagonized by selective histamine H2 receptor antagonist ranitidine （n=13） but not influenced by selective histamine H1 receptor antagonist triprolidine （n=15）. These results demonstrate that histamine excites cerebellar FN cells via the histamine H2 receptor mechanism and suggest that the hypothalamocerebellar histaminergic fibers may modulate cerebellar FN-mediated sensorimotor integration through their excitatory innervations on FN neurons.
