Bongartz(2013) and Ringel(2011) proved that there is no gaps in the sequence of lengths of indecomposable modules for the ?nite-dimensional algebras over algebraically closed ?elds. The present paper mainly studies this "no gaps" theorem as to cohomological length for the bounded derived category Db(A) of a gentle algebra A: if there is an indecomposable object in D^b(A) of cohomological length l > 1, then there exists an indecomposable with cohomological length l-1.

The Chen zhang Pot, made in the late Warring States period is an openwork bronze pot with gold and silver inlay. It was identified as a first-class historical relic of the nation by the State Administration of Cultural Heritage in 2001. To explore its manufacturing techniques, XRF, CT and X-Ray photograph microscopic observation were adopted for the non-destructive examination of the Chen zhang Pot. The analysis data show that many parts of the Chen zhang Pot were cast separately, and then assembled. It also shows that the composition proportion of each part of the Chen zhang Pot is different; and the bronze color, hardness and tensile strength are different for each alloy proportion. A variety of decoration techniques were adopted in the manufacturing process, which make the color more diverse and gorgeous. The openwork decoration is the most complex part of the pot, and the gold and silver decoration technique also represents the high level manufacturing technology in the Warring States period. In summary, the Chen zhang Pot is a unique art treasure, and as a specimen it allows us to study the bronze casting technology in the Warring States period.

A melt-cast Duan-zhang-Kim(DZK)mesoscopic reaction rate model is developed for the shock initiation of melt-cast explosives based on the pore collapse hot-spot ignition mechanism.A series of shock initiation experiments was performed for the Comp B melt-cast explosive to estimate effects of the loading pressure and the particle size of granular explosive component,and the mesoscopic model is validated against the experimental *** numerical simulations indicate that the initial density and formula proportion greatly affect the hot-spot ignition of melt-cast explosives.

A novel class of neural dynamics, zhang dynamics （ZD）, has been recently proposed for online time-varying problem solving. The design method of ZD is based on an indefinite error-monitoring function called the zhang function （ZF）, instead of the conventional norm-based scalar-valued energy function. In this paper, different ZD models based on different ZFs are proposed and developed for solving the time-varying inverse square root （TVISR） problem. In addition, this paper investigates the modeling of the proposed ZD models using MATLAB Simulink techniques. Results of the MATLAB Simulink modeling substantiate the efficacy and superiority of the ZD models for TVISR problem solving.
