    Alvania wangi Xu, Qi & Kong, sp. nov. (Mollusca, Gastropoda, Littorinimorpha, Rissoidae) was discovered within the intertidal zone in the Nanji Islands and Zhoushan Islands, Zhejiang Province, China. It has a radula characteristic of Alvania Risso, 1826, a protoconch sculptured with micro pits and lamellae between spiral lirae, and a teleoconch with growth lines and subobsolete cords. Specimens were examined using an integrative taxonomic approach incorporating morphological observations and phylogenetic analyses of concatenated mitochondrial 16S rRNA and nuclear 28S rRNA gene sequences. The findings suggest that the new species is sister to Alvania circinata A. Adams, 1861 and is probably endemic to the shallow waters of the East China Sea

    de YE Lingfeng 叶灵凤 traduit du chinois par Marie Laureillard YE Lingfeng (1905-1975), né à Nankin, est une figure littéraire importante des années 1920, 1930. D’abord peintre, surnommé le « Beardsley chinois », il adhère à la société littéraire Création, aux côtés de Yu Dafu, son mentor. Il édite plusieurs revues littéraires et publie de nombreux romans dont Wei wancheng de chanhuilu (Confessions inachevées) en  1936. En 1938, il se fixe définitivement à Hong Kong où il poursuit ses activité..

    A Theory of Dark Pions

    No full text
    We present a complete model of a dark QCD sector with light dark pions, broadly motivated by hidden naturalness arguments. The dark quarks couple to the Standard Model via irrelevant Z- and Higgs-portal operators, which encode the low-energy effects of TeV-scale fermions interacting through Yukawa couplings with the Higgs field. The dark pions, depending on their CP properties, behave as either composite axion-like particles (ALPs) mixing with the Z or scalars mixing with the Higgs. The dark pion lifetimes fall naturally in the most interesting region for present and proposed searches for long-lived particles, at the LHC and beyond. This is demonstrated by studying in detail three benchmark scenarios for the symmetries and structure of the theory. Within a coherent framework, we analyze and compare the GeV-scale signatures of flavor-changing meson decays to dark pions, the weak-scale decays of Z and Higgs bosons to hidden hadrons, and the TeV-scale signals of the ultraviolet theory. New constraints are derived from B decays at CMS and from Z-initiated dark showers at LHCb, focusing on the displaced dimuon signature. We also emphasize the strong potential sensitivity of ATLAS and CMS to dark shower signals with large multiplicities and long lifetimes of the dark pions. As a key part of our phenomenological study, we perform a new data-driven calculation of the decays of a light ALP to exclusive hadronic Standard Model final states. The results are provided in a general form, applicable to any model with arbitrary flavor-diagonal couplings of the ALP to fermions.We present a complete model of a dark QCD sector with light dark pions, broadly motivated by hidden naturalness arguments.

    The Long-Lasting Influence of Ideological Prejudices: The Case of Ye Lingfeng (1905-1975), a Misunderstood Writer and Intellectual in Modern China

    Through the works and some biographical issues of Ye Lingfeng (1905-1975), one of the writers of the so-called Shanghai School (haipai, 海派), this paper aims to offer some hints of the multi-folded bunch of prejudices which the history of modern Chinese literature is intertwined with. To reach this goal, the following issues will be taken into consideration: 1. an analysis of Ye Lingfeng’s early production,  before his moving from mainland China to Hongkong –  with particular reference to  The Dream of a Virgin Chunüde meng, (处女的梦, Chunüde meng), in comparison with Ding Ling (丁玲) Miss Sophia’s Diary (Shafei nüshi de rij, 莎菲女士的日记); to which a much bigger success arose; 2.  a general description of the complicated issues which led inflicting on him the very unfair label of being a “traitor”,  moving from his clash with Lu Xun in the late The twenties and early Thirties to his “collaboration” with the Nationalist Party during the first period of his staying in Hong Kong; 3. an overview of his literary works in order to highlight his way to connect traditional and modern literary tradition, which – if prejudices were not working - could provide some suggestions to the core issue of the relationship between “classic” (feudal?) literature and the literature of New China
