We use the multiconfiguration Dirac-Hartree-Fock (MCDHF) method combined with the relativistic configuration interaction (RCI) approach (GRASP2K) to provide a consistent set of transition energies and radiative transition data for the lower n = 3 states in all Cl-like ions of astrophysical importance, from Cr VIII to Zn XIV. We also provide excitation energies calculated for Fe X using the many-body perturbation theory (MBPT, implemented within FAC). The comparison of the present MCDHF results with MBPT and with the available experimental energies indicates that the theoretical excitation energies are highly accurate, with uncertainties of only a few hundred cm−1. Detailed comparisons for Fe X and Ni XII highlight discrepancies in the experimental energies found in the literature. Several new identifications are proposed. Copyright © 2019, The Authors.

A covert communication scheme based on DNA microdots for port hopping

International Journal of Performability Engineering 2017年第5期13卷 598-609页

作者： Shi, Leyi Cui, Yuwen Liu, Xiaotong Sun, Hui Xue, Zhiyu Zhang, Shufen Qingdao266580 China Hebei Key Laboratory of Data Science and Application Tangshan063210 China North China University of Science and Technology Tangshan063210 China

Port hopping is an effective solution for Moving Target Defense (MTD), which randomly changes the server's service port number to provide a robust communication against malicious Denial of Service (DoS) and Distributed DoS (DDoS) attack. Although a series of novel and feasible port hopping mechanisms have been proposed and implemented, most of them cannot prevent the messages transmitted in the network from being intercepted by an attacker. This paper addresses the problem of defending the eavesdropping attack with the port hopping process. We propose a new module that combines the properties of port hopping and the encryption of DNA microdots to resist the eavesdropping attacks in the network. The proposed port hopping process is compatible with the UDP and TCP protocols, in which the four IP addresses equipped in the server stand for the different nucleotides of DNA strands. We implement the proposed scheme and conduct the theoretical analysis on it. The theoretical analysis and experimental results illustrate that the proposed scheme can effectively defend against the DoS/DDoS and eavesdropping attacks. © 2017 Totem Publisher, Inc.

Designing preamplifier for sensing atmospheric electrostatic field strength via supercapacitive sensor

In order to effectively obtain the signal from sensor, the analogy signal needs to be amplified and then converted into a digital signal for matching to the sensor characteristics. With a supercapacitive electric field sensor based on graphene aerogel, the response current signal from the electric field sensor is weak and unstable. Herein, a high gain and low noise preamplifier is developed, and an amplifier circuit with double T-type feedback network is proposed to reduce the Johnson noise for the amplifier. This design can reduce the thermal noise of resistance by using the smaller resistance under the same gain, and it can effectively reduce the interference of peak noise by adding the feedback capacitance, so as to improve the detection accuracy. The simulation results show that under the same gain condition, the Johnson noise can be reduced by 46% and the detection accuracy can be improved by 12% compared with the traditional T-type feedback network.

The CUPID-Mo experiment at the Laboratoire Souterrain de Modane (France) is a demonstrator for CUPID, the next-generation ton-scale bolometric 0νββ experiment. It consists of a 4.2 kg array of 20 enriched Li2Mo100O4 scintillating bolometers to search for the lepton-number-violating process of 0νββ decay in Mo100. With more than one year of operation (Mo100 exposure of 1.17 kg×yr for physics data), no event in the region of interest and, hence, no evidence for 0νββ is observed. We report a new limit on the half-life of 0νββ decay in Mo100 of T1/2>1.5×1024 yr at 90% C.I. The limit corresponds to an effective Majorana neutrino mass ⟨mββ⟩<(0.31–0.54) eV, dependent on the nuclear matrix element in the light Majorana neutrino exchange interpretation.

Effect of gradient temperature rolling on microstructure of initial pass of ultra-heavy plates

IOP Conference Series: Earth and Environmental science 2019年第2期233卷

作者： Bo Xu Hongyuan Fu Xin Zhang Shouyuan Bian Ling Yan Shengli Li College of Metallurgy and Energy North China University of Science and Technology Hebei Tangshan 063210 China Key Laboratory of metallurgical engineering University of Science and Technology Liaoning Anshan Liaoning 114051 China State key laboratory of metal materials for Marine equipment and their application Anshan Iron and Steel Group Corporation Anshan 114021 China

In this paper, the gradient temperature rolling (GTR) method is used to establish the rolling model of the first two passes by using the deform-3D finite element software. The variation of temperature field, stress field, static recrystallization and average grain size of ultra-heavy plate slab under different conditions is systematically studied. Test result shows that the water cooling between the passes can form a temperature gradient layer (about 30mm) of a certain thickness on the surface of the rolled blank, the deformation of the core can be effectively improved during the rolling process, the static recrystallized grain size and average grain size of the surface of the rolled part are more obvious than the uniform temperature rolling; in addition, since the surface temperature of the water-cooled product is low, the amount of deformation is small, and metastable dynamic recrystallization does not occur.

Title-guided encoding for keyphrase generation

keyphrase generation (KG) aims to generate a set of keyphrases given a document, which is a fundamental task in natural language processing (NLP). Most previous methods solve this problem in an extractive manner, while recently, several attempts are made under the generative setting using deep neural networks. However, the state-of-the-art generative methods simply treat the document title and the document main body equally, ignoring the leading role of the title to the overall document. To solve this problem, we introduce a new model called Title-Guided Network (TG-Net) for automatic keyphrase generation task based on the encoderdecoder architecture with two new features: (i) the title is additionally employed as a query-like input, and (ii) a titleguided encoder gathers the relevant information from the title to each word in the document. Experiments on a range of KG datasets demonstrate that our model outperforms the state-of-the-art models with a large margin, especially for documents with either very low or very high title length ratios.

This paper describes the planar schottky diode based subharmonic mixers currently being developed at the EHF key laboratory of Fundamental science of Universtity of Electronic science and Technology of China. Hybrid and integrated GaAs Schottky diode based 330GHz and 420GHz subharmonic mixers are designed, fabricated and measured. Test results show that the minimum conversion loss of 330GHz monolithic integrated sub-harmonic mixer is 10.4dB at 328GHz, SSB conversion loss is less than 14.7dB from 320GHz to 340GHz when the LO power is 5mW;the minimum conversion loss of the 420GHz hybrid sub-harmonic mixer is 9.99dB at 406GHz, the SSB conversion loss is less than 15dB from 380GHz to 430GHz when the local power is 6dBm;the minimum conversion loss of the 420GHz heterogeneous integrated sub-harmonic mixer is 10dB at 419GHz and 422GHz, SSB conversion loss is less than 14.7dB over 400GHz to 440GHz frequency range when the LO power is 5.2dBm at 210GHz. © 2017 Applied Computational Electromagnetics Society.
