在过去的十年里,燃煤电厂SO2排放物的控制系统,已被证实是非常昂贵和不可靠的,这一点已不再是什么秘密了。即使在以前,当SO2排放物控制系统被证明是实用的时候,电厂也是不得不安装和运用烟道气脱硫系统（FGD）。但是人们还不曾普遍认识到,电厂已经在改进SO2排放物的控制方面走在了前面。传统的FGD系统,即所谓“湿式洗涤器”,是燃煤电厂里最昂贵的环境控制辅助系统。对于今天新建的一座电厂,洗涤器的费用仅次于锅炉本身的费用。若是改造,FGD

Introduction Mycotoxins are toxic secondary metabolites of various fungi, mainly those belonging to the genera Fusarium, Aspergillus and Penicillium. The major classes of mycotoxins in animal feed industry are aflatoxins, zearalenone, trichothecenes (e.g. deoxynivalenol,1-2 toxin, DAS), ochratoxin A, fumonisins and the ergot alkaloids. Their global occurrence is considered to be a major risk factor, as according to the Food and Agriculture Organization (FAO) as much as 25% of the world’s crops are affected annually despite increased efforts of prevention (Cortyl and Heidler, 2001).

exceptional points(ePs) are degeneracies of non-Hermitian operators where, in addition to the eigenvalues, the corresponding eigenmodes become degenerate. Classical and quantum photonic systems with ePs have attracted tremendous attention due to their unusual properties, topological features, and an enhanced sensitivity that depends on the order of the eP, i.e., the number of degenerate eigenmodes. Yet, experimentally engineering higher-order ePs in classical or quantum domains remain an open challenge due to the stringent symmetry constraints that are required for the coalescence of multiple eigenmodes. Here, we analytically show that the number-resolved dynamics of a single, lossy waveguide beam splitter, excited by N indistinguishable photons and post-selected to the N-photon subspace, will exhibit an eP of order N+1. By using the well-established mapping between a beam splitter Hamiltonian and the perfect state transfer model in the photon-number space,we analytically obtain the time evolution of a general N-photon state and numerically simulate the system’s evolution in the post-selected manifold. Our results pave the way toward realizing robust, arbitrary-order ePs on demand in a single device.
