The synthesis of new Schiff base-like ligands with asymmetric substituents pattern and their iron complexes with pyridine as axial ligand is described. Two of the ligands and one of the iron（II） complexes were characterized by single crystal X-ray structure analysis. One of the the iron（II） complexes shows spin crossover behavior while the others remain in the high spin state. The influence of the reduced symmetry of the ligand on the properties of the complexes is discussed.

Train traffic rescheduling is a complicated and large-scaled combinatorial problem. According to the characteristics of China railway system and from the point of practical use, this paper introduces a rule-based train traffic reschedule interactive simulator. It can be used as a powerful training tool to train the dispatcher and to carry out experimental analysis. The production rules are used as the basic for describing the processes to be simulated. With the increase of rule, users can easily upgrade the simulator by adding their own rules.

Recent experiments have provided direct evidence on the apparent existence of the synthesis of the neutron from a proton and an electron according to the reaction p+e→n+v. much along Rutherford's original conception of the neutron. These findings have received indirect, yet significant experimental confirmations in the Bose-Einstein correlation, the behaviour of the meanlife of unstable hadrons with speed, superconductivity, and other fields, which are such to warrant additional studies. In this paper we present a quantitative theoretical study on the apparent tendency of all massive particles to form a bound state at distances equal or smaller than their wavepackets which is enhanced at low energy. The study is centrally dependent on the isominkowskian geometrization of the mutual wave-overlapping and related isopoincaré symmet- ry proposed by this author back in 1983. While prohibited in the conventional Minkowski space under the conventional Poincare' symmetry, the synthesis herein considered become possible under our covering isotopic formulations thanks to new renormalizations of intrinsic characteristics of particles originating from nonlocal and nonhamitonian effects in mutual waver-overlappings. If experimenatlly confirmed, the studies here submitted would therefore imply that, not only the neutron can be produced via the proton-electron synthesis, but all unstable hadrons can be artificially produced vin the synthesis of ligther hadrons usually selected in the decay with the lowest mode, which would then acquire the meaning of tunnel effect of the constituents. Comparison and compatibility with conventional quark models are also considered for detailed study elsewhere.

The scientific scene of this century has been dominated by the special and general relativities. In this paper we first recall that these relativities were not conceived for unlimited physical conditions, but solely for exterior problems (motion of point-like test bodies in the homogeneous and isotropic vacuum). We then show that the relativities are inapplicable (rather than violated) for the more general interior problems (motion of extended test bodies within inhomogeneous and anisotropic physical media) on numerous, independent, topological, geometric, analytic and other grounds. We also outline the rather numerous problematic aspects of general relativity for exterior problems in vacuum, while the problematic aspects of the special relativity in vac- uum are treated elsewhere in this volume. We also point our rather serious insufficiencies of the special and general relativities for an effective representation of antimatter, beginning at a classicalwastrophysical level and then continuing at the operator-particle level. The paper ends with a brief outline of the so-called isotopic generalization of the special and general relativities initiated by this author back in 1978 when at Harvard University under support from the U. S. Department of Energy, and subsequently studied by a number of mathematicians, theoreticians and experimentalists. These isotopic studies are presented as an indication of the true scientific renaissance in mathematics, physics, superconductivity and other fields which has been stimulated by the limitations and problematic aspects of the special and general relativities. These studies are coordinated by the Istituto per la Ricerca di base in Italy. All scholars interested in truly fundamental advances in mathematics, physics, superconductivity and other disciplines are encouraged to participate in this collegial ef- fort.

The feasibility of population transfer from a populated level via an intermediate state to the target level driven by few-cycle pulses is theoretically discussed. The processes of on- or far-resonance stimulated Raman scattering with sequential or simultaneous ultrashort pulses are investigated respectively. We find that the ultrashort pulses with about two optical cycles can be used to realize the population operation. This suggests that the population transfer can be completed in the femtosecond time scale. At the same time, our simulation shows that the signal of the carrier-envelope-phase-dependent effect can be enlarged due to quantum interference in some conditions. Our theoretic study may promote the research on the coherent control via ultrashort pulses in the related fields.

Two types of changes in apparent resistivity (AR) have been linked to earthquake occurrences. This paper studies the changes and their causes, in detail with the ultimate purpose of developing and assessing a method of earthquake (EQ) prediction. The AR changes of the first type (CFT) are considered to be precursors related to earthquakes (EQs); these appear mostly in the medium-term period before EQs and in the short-term period preceding EQs. The changes of the second type (CST) are characterized by a turning anomaly of a long-trend AR variation or the drastically descending/ascending anomaly superimposed on such a variation; these appear synchronously in large areas, such as the Chinese mainland, and northern and northwestern China, ect. Their spatio-temporal clusters correspond well to high seismicities in the areas and distant great EQs around the Chinese mainland. based on the behaviors of the two types of changes, the AR changes observed prior to the Ms8.0 Wenchuan EQ of 2008 are studied. The results show that in the medium-term period before the EQ, noticeable anomalies appeared synchronously at four stations around the Songpan-Ganzi active block, but only weak upward changes were observed in the short-term period preceding the EQ, which caused the prediction of the imminent EQ to fail.

＜正＞ The detection of nucleic acid interaction with immobilized oligonucleotide probes for DNA microarray applications are greatly increased recently. However, most of the current technologies are limited by the complex DNA immobilization procedures, the need for fluorescene or radioactivity labeling. DNA chips must offer lower cost and greater material effiencies to gain acceptance. In this work, we investigate the effect of simple electrostatic charging on the interactions of surface-bound monolayer nucleic films with unlabeled
