| 1 | Algorithms for computing the global infimum and minimum of a polynomial function显示文摘By catching the so-called strictly critical points,this paper presents an effective algorithm for computing the global infimum of a polynomial function.For a multivariate real polynomial f ,the algorithm in this paper is able to decide whether or not the global infimum of f is finite.In the case of f having a finite infimum,the global infimum of f can be accurately coded in the Interval Representation.Another usage of our algorithm to decide whether or not the infimum of f is attained when the global infimum of f is finite.In the design of our algorithm,Wu’s well-known method plays an important role. | ShuiJing Xiao GuangXing Zeng | 2012 | Science China Mathematics2012，55，4： | 5 |
| 2 | Mechanism of petroleum migration and accumulation in western China's superposed basins显示文摘In western China,most petroliferous basins are superposed due to their multi-periodic tectonic evolution,and the mechanisms of petroleum migration and accumulation are so complex that much more sophisticated methodologies are necessary for depiction of these mechanisms and identification of petroleum occurrences.For this purpose,in this article,a new methodology was formulated which includes:(1) vertical identification of petroleum migration and accumulation fluid dynamic systems in the superposed basins;(2) analysis of the effect of large scale regional faults and fault combinations on the fluids exchange between the vertically identified different systems;(3) analysis of petroleum migration and accumulation in each vertically identified system,and establishment of appropriate geological model of petroleum migration and accumulation for each vertically identified system.Using this methodology,the satisfactory results obtained in the Lunnan Uplift of Tarim Basin and Ludong Uplift of Jungar Basin case studies are:(1) existence of different vertical fluid dynamic systems in western China's superposed basins which are very necessary for understanding the mechanism of petroleum migration and accumulation;(2) in deep system,long-distance lateral petroleum migration and accumulation mainly take place along the long time exposed unconformity with weathered,fractured or karst reservoir rocks;(3) regional faults are the main conducts for fluids migration from deep system up to middle and/or upper systems.As to middle and/or upper systems,regional faults play a role of ''petroleum source''.Small faults within middle and/or upper systems conduct petroleum to carrier beds with less impeding force;(4) petroleum migrated from deep system vertically up to middle and/or upper systems will migrate laterally in carrier beds of these systems and accumulate to form pools near or far from faults. | Kang Yonghong Li Peijun Qi Xuefeng Wen Yonghong | 2012 | International Journal of Mining Science and Technology2012，22，2： | 2 |

| 4 | Development of a real time PCR assay for rapid detection of Vibrio parahaemolyticus from seafood显示文摘A real time PCR assay for the detection of Vibrio para-haemolyticus in seafood samples was developed using a novel specific target and a competitive internal ampli-fication control(IAC).The specificity of this assay was evaluated using 390 bacterial strains including V.parahaemolyticus,and other strains belonging to Vibrio and non-Vibrio species.The real time PCR assay un-ambiguously distinguished V.parahaemolyticus with a detection sensitivity of 4.8 fg per PCR with purified genomic DNA or 1 CFU per reaction by counting V.parahaemolyticus colonies.The assays of avoiding interference demonstrated that,even in the presence of 2.1μg genomic DNA or 107 CFU background bacteria,V.parahaemolyticus could still be accurately detected.In addition,the IAC was used to indicate false-negative results,and lower than 94 copies of IAC per reaction had no influence on the detection limit.Ninety-six sea-food samples were tested,of which 58(60.4%)were positive,including 3 false negative results.Conse-quently,the real time PCR assay is effective for the rapid detection of V.parahaemotyticus contaminants in seafood. | Bin Liu Xiaohua He Wanyi Chen Shuijing Yu Chunlei Shi Xiujuan Zhou Jing Chen Dapeng Wang Xianming Shi | 2012 | Protein & Cell2012，3，3： | 2 |

| 10 | The Invertibility of Rational Univariate Representations显示文摘In this paper,the so-called invertibility is introduced for rational univariate representations,and a characterization of the invertibility is given.It is shown that the rational univariate representations,obtained by both Rouillier’s approach and Wu’s method,are invertible.Moreover,the ideal created by a given rational univariate representation is defined.Some results on invertible rational univariate representations and created ideals are established.Based on these results,a new approach is presented for decomposing the radical of a zero-dimensional polynomial ideal into an intersection of maximal ideals. | XIAO Shuijing ZENG Guangxing | 2022 | Journal of Systems Science & Complexity2022，35，6： | 1 |

| 15 | Equality-constrained minimization of polynomial functions显示文摘This paper investigates the equality-constrained minimization of polynomial functions. Let R be the field of real numbers, and R[x1,..., xn] the ring of polynomials over R in variables x1,..., xn. For an f ∈ R[x1,..., xn] and a finite subset H of R[x1,..., xn], denote by V(f : H) the set {f( ˉα) | ˉα∈ Rn, and h( ˉα) =0, ? h ∈ H}. We provide an effective algorithm for computing a finite set U of non-zero univariate polynomials such that the infimum inf V(f : H) of V(f : H) is a root of some polynomial in U whenever inf V(f : H) = ±∞.The strategies of this paper are decomposing a finite set of polynomials into triangular chains of polynomials and computing the so-called revised resultants. With the aid of the computer algebraic system Maple, our algorithm has been made into a general program to treat the equality-constrained minimization of polynomials with rational coefficients. | XIAO ShuiJing ZENG GuangXing | 2015 | Science China Mathematics2015，58，10： | 0 |
| 16 | Decomposing the Radicals of Polynomial Ideals by Rational Univariate Representations显示文摘In this paper,the notion of rational univariate representations with variables is introduced.Consequently,the ideals,created by given rational univariate representations with variables,are defined.One merit of these created ideals is that some of their algebraic properties can be easily decided.With the aid of the theory of valuations,some related results are established.Based on these results,a new approach is presented for decomposing the radical of a polynomial ideal into an intersection of prime ideals. | XIAO Shuijing ZENG Guangxing | 2023 | Journal of Systems Science & Complexity2023，36，6： | 0 |
| 17 | SEMI-ALGEBRAICALLY CONNECTED COMPONENTS OF MINIMUM POINTS OF A POLYNOMIAL FUNCTION显示文摘In a recent article,the authors provided an effective algorithm for both computing the global infimum of / and deciding whether or not the infimum of / is attained,where / is a multivariate polynomial over the field R of real numbers.As a complement,the authors investigate the semialgebraically connected components of minimum points of a polynomial function in this paper.For a given multivariate polynomial / over R,it is shown that the above-mentioned algorithm can find at least one point in each semi-algebraically connected component of minimum points of / whenever /has its global minimum. | XIAO Shuijing ZENG Guangxing | 2013 | Journal of Systems Science & Complexity2013，26，6： | 0 |
| 18 | Determination of the limits for multivariate rational functions显示文摘The purpose of this paper is to solve the problem of determining the limits of multivariate rational functions.It is essential to decide whether or not limxˉ→0f g=0 for two non-zero polynomials f,g∈R[x1,...,xn]with f(0,...,0)=g(0,...,0)=0.For two such polynomials f and g,we establish two necessary and sufcient conditions for the rational functionf g to have its limit 0 at the origin.Based on these theoretic results,we present an algorithm for deciding whether or not lim(x1,...,xn)→(0,...,0)f g=0,where f,g∈R[x1,...,xn]are two non-zero polynomials.The design of our algorithm involves two existing algorithms:one for computing the rational univariate representations of a complete chain of polynomials,another for catching strictly critical points in a real algebraic variety.The two algorithms are based on the well-known Wu’s method.With the aid of the computer algebraic system Maple,our algorithm has been made into a general program.In the final section of this paper,several examples are given to illustrate the efectiveness of our algorithm. | XIAO ShuiJing ZENG GuangXing | 2014 | Science China Mathematics2014，57，2： | 0 |
