    The paper [M.-L. Hsieh and S. Yamana, Restriction of Eisenstein series and Stark-Heegner points, arXiv:2002.11858.] was finished later after the conference. The text of this note has some overlapping with the content in [M.-L. Hsieh and S. Yamana, Restriction of Eisenstein series and Stark-Heegner points, arXiv:2002.11858.].This short note is written based on my talk on a joint work with Shunsuke Yamana [HY20] in the RIMS conference "Analytic, geometric and p-adic aspects of automorphic forms and L-functions" during January 20-24, 2020. The author thanks the organizers for their hospitality during the conference

    Direct observation of spin-polarized surface states in the parent compound of a topological insulator using spin- and angle-resolved photoemission spectroscopy in a Mott-polarimetry mode

    We report high-resolution spin-resolved photoemission spectroscopy (spin-ARPES) measurements on the parent compound Sb of the recently discovered three-dimensional topological insulator Bi1−xSbx (Hsieh et al 2008 Nature 452 970, Hsieh et al 2009 Science 323 919). By modulating the incident photon energy, we are able to map both the bulk and the (111) surface band structure, from which we directly demonstrate that the surface bands are spin polarized by the spin–orbit interaction and connect the bulk valence and conduction bands in a topologically non-trivial way. A unique asymmetric Dirac surface state gives rise to a k-splitting of its spin-polarized electronic channels. These results complement our previously published works on this class of materials and re-confirm our discovery of topological insulator states in the Bi₁₋ₓSbₓ series

    The composition of polysaccharides in primary walls of litchi chinensis sonn

    The structure of polysaccharides from the primary cell walls of Litchi chinensis pericarp tissues is determined using various approaches, including chromatographic, spectroscopic, chemical and enzymatic methods. These primary cell walls contain mainly pectins and fucosylated xyloglucans. Further, much smaller proportions of pure xylans were also characterized, which gives evidence for the presence of nonbranched pure xylans in eudicotyledons. As far as we are aware, this is the first report detailing the structure of polysaccharides in the primary cell walls of L. chinensis pericarp tissues.Yves S.-Y. Hsieh and Chi-Yan Won
