卡斯克小说《转折》中的真实与共识

当代英国小说在回望与实验中不断反思现实主义书写的价值。《转折》是作家蕾切尔·卡斯克探索叙述与现实关系的三部曲之一。本文将小说置于当代英国“后真相”的语境中加以解读,考察作家如何聚焦公共生活,揭示真实与共识的关系。小说以独特的文学策略审视了共识瓦解的社会空间和心理空间,揭示出真相的流转过程。小说摒弃追问共识的伤感主义倾向,以“去情节化”演绎新的共识路向,彰显个体叙事的不可化约性,还表达了文学叙述的认识与疗愈价值。小说借助美学形式的探索呈现出对英国社会共识问题的新思考,体现了当代现实主义书写的潜能。

一部力透史家情怀与史学认知之作——《转折——以早期中英关系和〈南京条约〉为考察中心》解读

史学著作贵客观公允,这已是治史学人之共识。然这一研究取向并不排拒史家情感之表达。其实,一部堪称上乘的史学论著,不仅要能够尽可能准确地还原历史原貌,尽可能客观地评价历史人物与历史事件,从而得出令人信服的历史结论,而且要能够透过其述论,较全面深入地展示史家的史学情怀与史学认知。郭卫东教授的近著《转折——以早期中英关系和<南京条约>为考察中心》,正是这样一部力透作者的强烈的爱国情怀与深邃的史学认识的史学代表作,是近些年来中国近代史研究的重要成果。

转折

怒放的百合花散发出狂野的气息，飞扬的发丝摇曳着澎湃的激情，惟有幽深的眼眸掠过朦胧的悲哀。明明知道只是一幅100多年前的插画而已，每每看到常有一种恍惚的媪馨。

Mechanism of Reverse Snapback on I-V Characteristics of Power SITHs with Buried Gate Structure

The reverse snapback phenomena （RSP） on I-V characteristics of static induction thyristors （SITH） are physically researched. The I-V curves of the power SITH exhibit reverse snapback phenomena, and even turn to the conducting-state,when the anode voltage in the forward blocking-state is increased to a critical value. The RSP I-V characteristics of the power SITH are analyzed in terms of operating mechanism, double carrier injection effect, space charge effect, electron-hole plasma in the channel, and the variation in carrier lifetime. The reverse snapback mechanism is theoretically pro- posed and the mathematical expressions to calculate the voltage and current values at the snapback point are presented. The computing results are compared with the experiment values.

Informational digital diagrams applied to predict spring wind,snow,and sandstorms

Using informational digital diagrams, we analyzed the snow event that occurred on Feb 26, 2006 and the sandstorm on Apr 11, 2006 in Xi＇an. Results indicate that, under similar weather circumstances, different events evidently exhibit unique vertical structure features. Informational digital diagrams provide a method for transitional weather prediction, a problem for present extrapolative analysis system.

Waveguide Optimization for a 9.0μm GaAs-Based Quantum Cascade Laser

Improved waveguide designs for 9.0μm GaAs-based quantum cascade laser （QCL） structures are presented. Modal losses and confinement factors are calculated for TM modes with the transfer matrix method （TMM） and effective index method （EIM）. The thicknesses of the cladding layer and waveguide layer, the ridge-width, and the cavity length are all taken into account. Appropriate thicknesses of epilayers are given with lower threshold gain and more economical material growth time.

200Ms/s 177mW 8bit Folding and Interpolating CMOS A/D Converter

A CMOS folding and interpolating analog-to-digital converter (ADC) for embedded application is described.The circuit is fully compatible with standard digital CMOS technology.A modified folding block implemented without resistor contributes to a small chip area.At the input stage,offset averaging reduces the input capacitance and the distributed track-and-hold circuits are proposed to improve signal-to-noise-plus-distortion ratio.The 200Ms/s 8bit ADC with 177mW total power consumption at 3.3V power supply is realized in standard digital 0.18μm 3.3V CMOS technology.

The roles of the proteasome pathway in signal transduction and neurodegenerative diseases

There are two degradation systems in mammalian cells, autophagy/lysosomal pathway and ubiquitin-proteasome pathway. Proteasome is consist of multiple protein subunits and plays important roles in degradation of short-lived cellular proteins. Recent studies reveal that proteasomal degradation system is also involved in signal transduction and regulation of various cellular functions. Dysfunction or dysregulation of proteasomal function may thus be an important pathogenic mechanism in certain neurological disorders. This paper reviews the biological functions of proteasome in signal transduction and its potential roles in neurodegenerative diseases.

Reversal of monthly East Asian winter air temperature in 2020/21 and its predictability

In this study,the reversal of monthly East Asian winter air temperature(EAWT) in 2020/21 and its predictability were investigated.The reversal of monthly EAWT in 2020/21 was characterized by colder temperatures in early winter(December 2020 to mid-January 2021) and warmer temperatures in late winter(mid-January to February 2021).Results show that the reversal in the intensity of the Siberian high(SH) also occurred between early and late winter in 2020/21.In early winter,as the Barents-Laptev sea ice in the previous September(i.e., in2020) reached a minimum for the period 1981-2020,the SH was strengthaned via a reduction of the meridional gradient between the Arctic and East Asia.In late winter,as a sudden stratospheric warming occurred on 5 January 2021,the stratospheric polar vortex weakened,with the weakest center shifting to North America in January.Subsequently,the negative Arctic Oscillation-like structure shifted towards North America in the middle and lower troposphere,which weakened the SH in late winter.Furthermore,the predictability of the reversal in EAWT in 2020/21 was validated based on monthly and daily predictions from NCEP-CFSv2(National Centers for Environment Prediction-Climate Forecast System,version 2).The results showed that the model was unable to reproduce the monthly reversal of EAWT.However,it was able to forecast the reversal date(18 January 2021)of EAWT at lead times of 1-20 days on the daily scale.

Numerical investigation on flow and heat transfer characteristics of corrugated tubes with non-uniform corrugation in turbulent flow

Based on finite volume method, the pressure drop and heat transfer characteristics of one smooth tube and ten different axisymmetric corrugated tubes, including two with uniform corrugation and eight with non-uniform corrugation, have been studied. A physical model of the corrugated tube was built, then the numerical simulation of the model was carried out and the numerical simulation results were compared with the empirical formula.The results show that: the friction factor decreases with the increase of Reynolds number ranging from 6000 to 57000, the value of which in the corrugated tubes with non-uniform corrugation(tube 03–10) are smaller than those with uniform corrugation(tube 01–02). The geometry parameters of tube(01) have advantages on the heat transfer enhancement in low Reynolds number flow region(from 6000 to 13000) and tube(07–08)have advantages on the heat transfer enhancement in high Reynolds number flow region(from 13000 to 57000). The vortex, existed in each area between two adjacent corrugations called second flow region, is the root of the enhancement on heat transfer in the corrugated tubes. The effectiveness factor decreases with the increasing of Reynolds number and the performances of the corrugated tubes with pitch of 12.5 mm have advantages than these of 10 mm under the same corrugation geometric parameter.

A novel coupled quantum well with large negative electro-refractive index change and low absorption loss

In order to solve excessive insertion loss and low on/off ratio in quantum well reflection-type waveguide optical switches, a novel InGaAs/InAlAs coupled quantum well structure is proposed. In the case of low applied electric field （F=19 kV/cm） and low absorption loss （ et ~ 61.2 cm-1）, a large negative field-induced refractive index change （ A n=-0.0134） is obtained in the novel coupled quantum well structure at the operating wavelength （ 2 =1550 rim）. The value is larger by over one to two order of maL, nitude comoared to that in a rectanaular ouantum well （ROW） on the above same work conditions.

Tas the Lewisian Turning Point Arrived in China？- An Empirical Study of China＇s Dual Economy Transition in Labor Market Based on Data of 284 Cities

Labor shortage and the rise of wages in China have generated heated debate on the arrival of the Lewisian Turning Point. Based on an empirical study of macroeconomic data for 284 prefecture-level cities, this paper argues that the dual economy transition in China involves the coexistence of urbanization, industrialization and open economy. However, China has not yet arrived at the Lewisian Turning Point, because wage gaps between different industries and regions still exist and surplus labor is still being attracted to the labor-intensive manufacturing and tertiary industries in the eastern provinces. External economic shock and the mismatch between industrialization and urbanization are the primary causes of the coexistence of labor surplus and labor shortage.
