New functional molecular markers for plants in the functional genomics era

ZHAO Xue,XIE Hua,MA Rong-cai,

中国生物工程杂志 , 2007,
Abstract: With the development of functional genomics,expressed sequence tags(ESTs)has become an important resource of PCR-based molecular markers for plants.The advancement in functional molecular markers for plants in the functional genomics era,including EST-SSR,CAPS,SNP,SRAP and TRAP were reviewed.Compared with conventional markers,the EST-derived markers are a novel type of molecular tool with remarkable advantages,such as being easily to develop,more informative,and highly transferable,especially for preferential targeting ORFs.Applications of the new functional molecular markers in plants genetics and breeding are summarized,such as construction of genetic linkage maps,important trait gene tagging location,comparative mapping,genetic diversity,cultivars identification and marker-assisted selection breeding.

Recovery of callback function for static binary translation

DING Song-yang,ZHAO Rong-cai,

计算机应用 , 2008,
Abstract: The recovery of callback function is a difficult problem in static binary translation. For the static binary translation of using C language as backend, this paper put forward a technique of analyzing the gap code and plugging codes into the target programs which searched the callback function address based on the source function address. This method can be implemented effectively. The speed of translated code running exceeds the speed of using interpreter.
Study of library functions recognizing technology in binary translation

计算机应用 , 2006,
Abstract: A new processor architecture poses significant risk to software developers, hinder the popularization of the new architecture. Binary translation offers solutions for automatically converting executable code to run on new architectures. The library functions recognizing technique in I2A binary translator was introduced. Especially a new approach of library function recognizing problem was given. It is a simple and practical method to recognizing library functions based on the calling conventions of IA-64 architecture and observation of the program instance. It is proved to be effective by the I2A translation system.

Abstract: Source to source translation is a very useful part in modern advanced compiler. It translates one programing language to another, which is equal in semantic and can be compiled again. Currently, source to source translation model of the latest Open64 version 5.0 is not consummate. It has to deal with the following two problems in source to source translation model. One problem is now it can't support dynamic array translation in Fortran90, the other problem is intermediate representation contains pseudo-register after aggressive optimizing. After translation process and intermediate representation were researched, information preservation mechanism was introduced to solve the translation problem of dynamic array and pseudo-register. Test results prove that the method can greatly improve the robustness of the source to source translation in Open64.
An automatic generation algorithm of MPI communication code

DU Peng,ZHAO Rong-cai,DONG Cun-li,

计算机应用 , 2007,
Abstract: Automatic parallel code generation by information from computation and data decomposition is an important optimization for achieving high performance on large-scale parallel machines. According to the theorem of Saman P.Amarasinghe and Lam, an algorithm was proposed that generated parallelized code automatically in the recognition tool MPT (Message Passing Interface). The performance of this algorithm was analyzed in the end.
Reverse optimize Technique based on speculation in reverse engineering

SU Ming,SONG Zong-yu,ZHAO Rong-cai,

计算机应用 , 2006,
Abstract: Speculative loads can reduce the latency associated with loads from memory. In order to make effective use of the capabilities of such architecture, compilers profoundly restructure the low level code of programs, however, making it potentially difficult to reconstruct the original program logic from an optimized executable. This complicates the task of software systems that statically analyze or modify executable programs. A technique for removing speculative instructions from itanium binary programs was described in a way that is guaranteed to preserve program semantics, thereby making the resulting programs easier to understand and more amenable to re-engineering using traditional reverse engineering techniques.
Seasonality of the Lagged Relationship between ENSO and the Northern Hemispheric Polar Vortex Variability
REN Rong-Cai,

大气和海洋科学快报 , 2012,
Abstract: This paper reports the seasonal feature of the relationship between ENSO and the stratospheric Polar Vortex Oscillation (PVO) variability in the Northern Hemisphere. It is shown that the lagged ENSO-PVO coupling relationship exhibits distinct seasonal feature, due to the strong seasonality of PVO and ENSO. Specifically, the PVO variability not only during winter, but also in autumn and spring months, is significantly correlated with ENSO anomalies leading by seasons; however, no significant effect of ENSO is found on the PVO variability in winter months of November and February. Although a significant ENSO effect is primarily observed when ENSO leads PVO by about one year, a significant correlation is also found between PVO in the following spring months (M+1A+1) and ENSO anomalies in the previous autumn (A-1S-1O-1N-1) when ENSO anomalies lead by about 18 months. The significant correlation between PVO in various seasons and the corresponding ENSO anomalies leading by seasons could be explicitly verified in most of the individual years, confirming that the lagged ENSO effect can largely modulate the seasonal timescale variability of PVO. Moreover, the composite spatial patterns of the zonal-mean temperature anomalies further show that the ENSO effect on the PVO in various seasons is related to the interannual variability of the seasonal timescale PVO events.
