    Ultrasonic-Assisted Synthesis of Two t-Butoxycarbonylamino Cephalosporin Intermediates on SiO2 by Feng Xue, Yibin Wei, Shengui Ju, Weihong Xing

    Published 2016-01-01
    “…Herein, we describe a facile and high efficient strategy for the synthesis of two forms of the 7β-t-butoxycarbonylamino-3-chloromethyl-3-cephem-4-carboxylates using ultrasonic irradiation. By SiO2 as weak Lewis acid catalyst, 4-methoxybenzyl 7β-t-butoxycarbonylamino-3-chloromethyl-3-cephem-carboxylate (Boc-ACLE) and benzhydryl 7β-t-butoxycarbonylamino-3-chloromethyl-3-cephem-4-carboxylate (Boc-ACLH) were successfully synthesized through the efficient protection of the N-t-butoxycarbonyl (N-Boc), and the reactions occurred at low temperature requiring short reaction times and exhibiting excellent isolated yields (96% and 96.2%, resp.). …”

    Bit-filling algorithm for fast subcarrier-selecting in ultrasonic through-metal communication by Linsen XU, Wei YANG, Hongxian TIAN, Tao WU

    Published 2020-11-01
    “…Aiming at the high complexity of the greedy bit-filling algorithm,a bit-filling algorithm for fast subcarrier-selecting used in ultrasonic through-metal communication was proposed.The approximate expression for the BER increment,which was used as the basis for selecting subcarriers in the greedy bit-filling algorithm,was derived by the BER approximation formula and Taylor formula.The subcarrier was selected first and then its BER was calculated.Therefore,it was unnecessary for the greedy bit-filling algorithm to calculate new BER of all subcarriers.The simulation results show that the proposed algorithm can achieve nearly the same data rate as the greedy bit-filling algorithm and save the BER calculation of about <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML"> <mfrac> <mn>3</mn> <mn>4</mn> </mfrac> </math></inline-formula> subcarriers,greatly reducing the amount of calculation.…”
