No full textMessageria scalarioides donghiana Z.-Y. Chen & L.-W. Lin, n. ssp. Figures 1E–H, 2A Holotype: HBUMM 10058, a big cave in mountains between Fengshan County [Hechi City] and Leye County [Baise City], Guangxi Zhuang Autonomous Region, China, ex coll. Hao Yang, 2012. Paratypes: CZY/1, LLW/1, same data as holotype. Etymology. This name comes from the local Zhuang language “dongh”, which means “cave”. Diagnosis. This subspecies can be distinguished from the nominate subspecies by the larger shell and wider lower whorls and umbilicus. Also, the aperture of M. scalarioides donghiana n. ssp. and 1/8 whorl behind it evidently deviate from the axis and umbilicus. Measurements. H = 3.70 mm, W = 3.37 mm, D A = 1.89 mm (holotype).

Yan SUN.</p> <p> <b>Etymology.</b> This name commemorates the first discovery of this genus in China.</p> <p> <b>Description.</b> Shell small (<5 mm), dextral, roundly conical, about 5.5 whorls. Shell translucent, relatively glossy, apical part light orange. Apex slightly convex, apical whorls depressed conical. Basal whorls ovoid. Protoconch oblique compared to shell axis, 1.25 whorls with matte surface. The next 0.5 whorl of the teleoconch with regularly spaced and equally high, weak ribs. The other whorls have well-spaced, high and thin main ribs, with a distinctly lower intermediate rib in between each pair of main ribs, ca. 9 (main and intermediate) ribs per 1 mm on body whorl. The intercostal distance increases with the whorls, and the strength (height) of the two kinds of ribs becomes same at umbilical area. Umbilicus deep.Aperture rounded, slightly oblique.

Unraveling nonadiabatic ionization and Coulomb potential effect in strong-field photoelectron holography
Full text linkCitation: Song, X. H., Lin, C., Sheng, Z. H., Liu, P., Chen, Z. J., Yang, W. F., . . . Chen, J. (2016). Unraveling nonadiabatic ionization and Coulomb potential effect in strong-field photoelectron holography. Scientific Reports, 6, 10. doi:10.1038/srep28392Strong field photoelectron holography has been proposed as a means for interrogating the spatial and temporal information of electrons and ions in a dynamic system. After ionization, part of the electron wave packet may directly go to the detector (the reference wave), while another part may be driven back and scatters off the ion(the signal wave). The interference hologram of the two waves may be used to extract target information embedded in the collision process. Unlike conventional optical holography, however, propagation of the electron wave packet is affected by the Coulomb potential as well as by the laser field. In addition, electrons are emitted over the whole laser pulse duration, thus multiple interferences may occur. In this work, we used a generalized quantum-trajectory Monte Carlo method to investigate the effect of Coulomb potential and the nonadiabatic subcycle ionization on the photoelectron hologram. We showed that photoelectron hologram can be well described only when the effect of nonadiabatic ionization is accounted for, and Coulomb potential can be neglected only in the tunnel ionization regime. Our results help paving the way for establishing photoelectron holography for probing spatial and dynamic properties of atoms and molecules
