集体的事情集体定——《班规》中到底要不要惩罚

从1987年我第一次在班级实行民主管理以来．每接一个新班，我都要“从零开始”地引导新生制定《班规》。每一个班的学生情况不完全一样，所以，制定的《班规》中某些具体的条文也不完全一样，但是《班规》的“可行性”“广泛性”“互制性”的基本原则和民主、平等的基本精神却是完全一致的。

Progress in the Study of False Smut Disease in Rice

Rice false smut disease is an increasing concern for research and production, not only because of the increasing epidemic occurrence in rice production, but also the intriguing specific pathogenesis of the disease to be a unique pathological system to enrich the molecular mechanism of plant-microbe interaction. Progresses have been achieved in the pathogen phylogenetic placement, the alternative hosts, the pathogen morphology and diversity, the toxins generated by false smut balls, the artificial inoculation method, and the pathogen transformation as well as rice resistance to the disease. However, it is still controversy on the infection process. It is not clear how the life cycle of this pathogen is coupled with the disease cycle. This review summarized our current understanding on the pathogen, the pathogenesis, and the rice resistance to the disease. Future work should pay attention to developing a more rapid and effective system to evaluate rice resistance and susceptibility to the disease, screening of rice germplasm for disease-resistance breeding, studying the resistance inheritance, and investigating the molecular mechanism of rice-false smut fungus interaction.

Fluid structure interaction for circulation valve of hydraulic shock absorber

Based on the working principle and the damping characteristic of hydraulic shock absorber, a fluid structure interaction method was presented, which was used to analyze the microcosmic and high-frequency processing mechanism of fluid structure interaction between circulation valve and liquid of hydraulic shock absorber. The fluid mesh distortion was controlled by the CEL language, and the fluid struc^tre interaction mathematical model was established. The finite element model was established by ANSYS CFX software and was analyzed by dynamic mesh technique. The local sensitive computational area was meshed by prismatic grid, which could reduce the negative volume problem during the simulation. The circulation valve and liquid of hydraulic shock absorber were simulated and analyzed under the condition of sinusoidal inlet velocity loads. Flow characteristic and dynamics characteristic were obtained. The pressure distribution and the displacement of circulation value were obtained, and the acceleration curve of circulation valve was simulated and analyzed. The conformity of the final simulation results with the experimental datum indicates that this method is accurate and reliable to analyze the dynamics characteristic between circulation valve and liquid of hydraulic shock absorber, which can provide a theoretical foundation for optimizing hydraulic shock absorber in the future.

Interaction mechanism between carboxylmethyl cellulose and iron ore concentrates in iron ore agglomeration

Carboxylmethyl cellulose(CMC) has become a commercial organic binder in agglomeration of iron ore concentrates. The relative molecular mass and degree of substitution(DS) of CMC have a large impact on its binding performance. The interaction mechanism between CMC and iron ore particles was analyzed through Zeta potential measurements, adsorption measurements and infrared spectra. The results show that the interaction is chemical adsorption-oriented and the CMC's adsorption performance is related to the properties of CMC as well as the type of iron oxides. CMC has a greater affinity to Fe2O3 than Fe3O4, and CMC with higher relative molecular mass shows a higher adsorption isotherm. Pelletization of practical iron ore concentrates added with CMC further illustrates that CMC with higher relative molecular mass or DS exhibits a better binding performance, which is consistent with the results of adsorption tests.

Advances on the Molecular Mechanism of the Interaction between Ralstonia solanacearum and Hosts

Ralstonia solanacearum is an important model phytopathogenic bacterium that causes bacterial wilt disease on many plant species and leads to serious economic losses. The interactions between R. solanacearum and host plants have become a model system for the study of plants and pathogens interactions. This paper reviews the advances on the molecular mechanisms between R. solanacearum and hosts interaction including the formation of plant innate immunity, the suppression of plant innate immunity by this pathogen and the activation of effector-triggered immunity. Furthermore, we made a prospect on how to utilize the interaction mechanism between R. solanacearum and hosts to control the disease.

Research on the interaction mechanism between quantum dots and radionuclides for the improvement of Cerenkov luminescence imaging

Cerenkov luminescence imaging(CLI) is a relatively new optical molecular imaging technique. The nature of Stokes shift in quantum dots(QD) can be used to improve the quality of CLI. However, the interaction mechanism of QD with Cerenkov light remains unclear. In this work, the interaction mechanism between QD and radionuclides emitting β rays, γ rays, and Cerenkov light was investigated. The 96-well plates were used to test the different levels of radioactivity of radionuclides with different QD concentrations. Transparent vials were used to determine the relationship between QD fluorescence intensity and the distance from QD to the radionuclide. In addition, black paper was used to block the transmission of Cerenkov light through the QD vials. A linear relationship was found between the number of photons and the radioactivity of radionuclides when the QD concentration was kept constant. Similarly, the number of photons was linearly related to the QD concentration when the radioactivity of radionuclides was kept constant. Furthermore, with the increases in the distance between radionuclides and quantum dots, the number of photons was exponentially decreased. Meanwhile, the number of photons emitted from QD excited by Cerenkov light accounted for 20% the total number of photons excited by 131 I radionuclide. The result proved that QD was not only excited by Cerenkov light but also by other rays.

Mechanisms of reproductive aging in the females

Aging is a developmental process occurring in all living organisms after reaching a critical developmental stage,characterized by progressive loss of functions until death.Different cells/tissues age differently depending on epigenetics and cell-cell interactions.While males maintain fertility for the most part of their life females only maintain reproductive ability for a short time compared with their lifespan.The interesting question is why and how the females lose fertility so quickly.There have been many hypotheses proposed from different perspectives and recent research has revealed unusual interactions between germ cells and somatic cells which may determine the lifespan of reproduction in the females.This review briefly discusses recent progress in reproductive aging in the well studied model,C.elegans,and focuses on the molecular mechanisms which may be conserved across all animals including humans.

TD-AltBOC:A new COMPASS B2 modulation

AltBOC(15,10) is the baseline of COMPASS B2 signal modulation.It is a BOC-like signal having different PN codes in the lower and the upper main split lobes,which allow one signal service per lobe.The two lobes can be received and processed separately like two BPSK(10) signals,or coherently processed to achieve better performance.Interoperability among COMPASS B2,Galileo E5 and GPS L5 is also achievable using AltBOC modulation.However,Galileo's 4-code AltBOC has drawbacks such as low efficiency and great receiver complexity.This paper presents a new modulation type named TD-AltBOC (Time Division AltBOC).The signal generation scheme and receiving method are presented,and are compared with AltBOC in the areas of power spectrum,ranging accuracy,anti-multipath performance,anti-interference performance,processing flexibility and complexity.Analysis results show TD-AltBOC has similar spectrum characteristics,interoperability,flexibility and anti-interference performance with AltBOC.When the frontend bandwidth is more than 50 MHz,TD-AltBOC can achieve better ranging accuracy and anti-multipath performance.It also has such advantages as high efficiency and low receiver complexity.TD-AltBOC could be a good solution to COMPASS B2 navigation signal.

Chiral polymer-based biointerface materials

Chirality is a unique phenomenon in nature. Chiral interactions play an important role in biological and physiological process- es, which provides much inspiration for scientists to develop cbiral materials. As a breakthrough from traditional materials, bi- ointerface materials based on chiral polymers have attracted increasing interest over the past few years. Such materials ele- gantly combine the advantages of chiral surfaces and traditional polymers, and provide a novel solution not only for the inves- tigation of chiral interaction mechanisms but also for the design of biomaterials with diverse applications, such as in tissue en- gineering and biocompatible materials, bioregulation, chiral separation and chiral sensors. Herein, we summarize recent ad- vances in the study of chiral effects and applications of chiral polymer-based biointerface materials, and also present some challenges and perspectives.

Investigating effects of nano-particles infiltrat

In this paper,we introduce our finding of the effects of C_(60) nanoparticles (NP) infiltration on mechanical properties of cell and its membrane.Atomic force microscopy (AFM) is used to perform indentation on both normal and C_(60) infiltrated red blood cells (RBC) to gain data of mechanical characteristics of the membrane.Our results show that the mechanical properties of human RBC membrane seem to be altered due to the presence of C_(60) NPs.The resistance and ultimate strength of the C_(60) infiltrated RBC membrane significantly decrease.We also explain the mechanism of how C_(60) NPs infiltration changes the mechanical properties of the cell membrane by predicting the structural change of the lipid bilayer caused by the C_(60) infiltration at molecular level and analyze the interactions among molecules in the lipid bilayer.The potential hazards and application of the change in mechanical characteristics of the RBCs membrane are also discussed.Nanotoxicity of C_(60) NPs may be significant for some biological cells.

Tunneling Dynamics of Dipolar Bosonic System with Periodically Modulated s-wave Scattering

Within the mean-field three-site Bose-Hubbard model, the tunneling dynamics of dipolar bosonic gas with a periodically modulation of s-wave scattering is investigated. The system experiences complex and rich coherent tunneling （CT）-coherent destruction of tunneling （CDT） transitions resulting from the correlated effect among the next-neighbor dipole-dipole interaction, the on-site interaction and the modulated s-wave scattering. In particular, The region of the modulated s-wave scattering for generating CT （CDT） is the widest （narrowest） when the on-site interaction and the next-neighbor dipole-dipole interaction have some correlated values, which are closely related to the tunneling energy and the interaction energy of the system. The correlated values for appearing CDT can be theoreticaJly gained from the tunneling energy and the interaction energy of the system.

Non-reciprocity compensation correction and antenna selection for optical large MIMO system

This paper exploits an optical large multiple input multiple output(MIMO) system.We first establish the non-reciprocity compensation correction factor to solve the channel non-reciprocity problem.Then we propose an antenna selection algorithm with the goal of realizing maximum energy efficiency(EE) when satisfying the outage EE.The simulation results prove that this non-reciprocity compensation correction factor can compensate beam energy attenuation gap and spatial correlation gap between uplink and downlink effectively,and this antenna selection algorithm can economize the number of transmit antennas and achieve high EE performance.Finally,we apply direct current-biased optical orthogonal frequency division multiplexing(DCO-OFDM) modulation in our system and prove that it can improve the bit error rate(BER) compared with on-off keying(OOK) modulation,so the DCO-OFDM modulation can resist atmospheric turbulence effectively.

Nonlinear interaction mechanisms of disturbances in supersonic flat-plate boundary layers

Due to the complexity of compressible flows,nonlinear hydrodynamic stability theories in supersonic boundary layers are not sufficient.In order to reveal the nonlinear interaction mechanisms of the rapidly amplified 3-D disturbances in supersonic boundary layers at high Mach numbers,the nonlinear evolutions of different disturbances in flat-plate boundary layers at Mach number 4.5,6 and 8 are analyzed by numerical simulations.It can be concluded that the 3-D disturbances are amplified rapidly when the amplitude of the 2-D disturbance reaches a certain level.The most rapidly amplified 3-D disturbances are Klebanoff type(K-type)disturbances which have the same frequency as the 2-D disturbance.Among these K-type 3-D disturbances,the disturbances located at the junction of upper branch and lower branch of the neutral curve are amplified higher.Through analyzing the relationship between the amplification rate and the spanwise wavenumber of the 3-D disturbances at different evolution stages,the mechanism of the spanwise wavenumber selectivity of K-type 3-D disturbances in the presence of a finite amplitude 2-D disturbance is explained.

Controlling Soliton Collisions of Condensates by Time-Dependence of Both Interactions and External Potential

Considering time-dependence of both interactions and external potential,we analytically study the collisional behaviors of two bright solitons in Bose-Einstein condensates by using Darboux transformation.It is found that for a closed external potential,the soliton-soliton distance is decreased with nonlinearly increased interactions,while the amplitude of each soliton increases and its width decreases.For linearly increased interactions but nonlinearly decreased external potential,especially,the atom transfer between two solitons is observed,different from previous theory of no atom transfer in solitons collision in a fixed external potential.In addition,it is shown that the collisional type,such as head-on,"chase",or collision period between two solitons,can be controlled by tuning both interactions and external potential.The predicted phenomena can be observed under the condition of the current experiments and open possibilities for future application in atoms transport.
