Purpose:To contribute to the study of networks and graphs.Design/methodology/approach:We apply standard mathematical thinking.Findings:We show that the distance distribution in an undirected network Lorenz majorizes the one of a chain.As a consequence,the average and median distances in any such network are smaller than or equal to those of a chain.Research limitations:We restricted our investigations to undirected,unweighted networks.Practical implications:We are convinced that these results are useful in the study of small worlds and the so-called six degrees of separation property.Originality/value:To the best of our knowledge our research contains new network results,especially those related to frequencies of distances. 展开更多

Quantum coherence is a relevant resource for various quantum information processing tasks,but it is fragile since it is generally affected by environmental noise.This is reflected in the loss of purity of the system,which in turn limits the amount of quantum coherence of it.As a consequence,a complementarity relation between coherence and mixedness arises.Previous works characterize this complementarity through inequalities between theℓ1-norm of coherence and linear entropy,and between the relative entropy of coherence and von Neumann entropy.However,coherence-mixedness complementarity is expected to be a general feature of quantum systems,regardless of the measures used.Here,an alternative approach to coherence-mixedness complementarity,based on majorization theory,is proposed.Vectorial quantifiers of coherence and mixedness,namely the coherence vector and the spectrum,respectively,are used,instead of scalar measures.A majorization relation for the tensor product of both vectorial quantifiers is obtained,capturing general aspects of the trade-off between coherence and mixedness.The optimal bound for qubit systems and numerical bounds for qutrit systems are analyzed.Finally,coherence-mixedness complementarity relations are derived for a family of symmetric,concave and additive functions.These results provide a deeper insight into the relation between quantum coherence and mixedness. 展开更多

Some majorization results for n,G∑ a,λ(A, B, 1) as well as the other functions are given. Furthermore, we find the coefficients bounds on |a_2| and |a_3| for functions in*n,G∑ a,λ(A_1, B_1, A_2, B_2, α_1, α_2), which is the bi-univalent functions defined by n,G ∑a,λ(A, B, α) and subordination.

Factor analysis (FA) is a time-honored multivariate analysis procedure for exploring the factors underlying observed variables. In this paper, we propose a new algorithm for the generalized least squares (GLS) estimation in FA. In the algorithm, a majorization step and diagonal steps are alternately iterated until convergence is reached, where Kiers and ten Berge’s (1992) majorization technique is used for the former step, and the latter ones are formulated as minimizing simple quadratic functions of diagonal matrices. This procedure is named a majorizing-diagonal (MD) algorithm. In contrast to the existing gradient approaches, differential calculus is not used and only elmentary matrix computations are required in the MD algorithm. A simuation study shows that the proposed MD algorithm recovers parameters better than the existing algorithms. 展开更多

Let a general quantum many-body system at a low temperature adiabatically cross through the vicinity of the system＇s quantum critical point. We show that the system＇s temperature is signif- icantly suppressed due to both the entropy majorization theorem in quantum information science and the entropy conservation law in reversible adiabatic processes. We take the one-dimensional transverse-field Ising model and the spinless fermion system as concrete examples to show that the inverse temperature might become divergent around the systems＇ critical points. Since the temper- ature is a measurable quantity in experiments, it can be used, via reversible adiabatic processes at low temperatures, to detect quantum phase transitions in the perspectives of quantum information science and quantum statistical mechanics. 展开更多

Using the axiomatic method,abstract concepts such as abstract mean,abstract convex function and abstract majorization are proposed.They are the generalizations of concepts of mean,convex function and majorization,respectively.Through the logical deduction,the fundamental theorems about abstract majorization inequalities are established as follows:for arbitrary abstract meanΣandΣ,and abstractΣ→Σstrict convex function f(x)on the interval I,if xi,yi∈I(i=1,2,...,n)satisfy that(x1,x2,...,xn)<nΣ(y1,y2,...,yn),thenΣ{f(x1),f(x2),...,f(xn)}≥Σ{f(y1),f(y2),...,f(yn)}.This class of inequalities extends and generalizes the fundamental theorem of majorization inequalities.Moreover,concepts such as abstract vector mean are proposed,the fundamental theorems about abstract majorization inequalities are generalized to n-dimensional vector space.The fundamental theorem of majorization inequalities about the abstract vector mean are established as follows:for arbitrary symmetrical convex set SRn,and n-variable abstract symmetricalΣ→Σstrict convex functionφ()on S,if,■∈S satisfynΣ■,thenφ(x)〈(y);if vector groupxi,yi∈S(i=1,2,...,m)satisfy{x1,x2,...,xm}〈Σn{y1,y2,...,ym},thenΣ{φ(x1),φ(x2),...,φ(xm)}Σ{φ(y1),φ(y2),...,φ(ym)}. 展开更多

This study addresses a critical gap in English language education at local application-oriented universities:how to enhance English majors’international communication competence(ICC)through a systematically designed public speaking and debate course.A pre-course survey revealed three major problems:low conceptual awareness of ICC,a severe skills imbalance between daily conversation and public persuasion,and a“China narrative void”where students could introduce traditional culture but not contemporary China.To address these gaps,a“Three-Phase,Four-Loop”instructional model grounded in the Production-Oriented Approach and Zone of Proximal Development theory was implemented in a 16-week course for second-year English majors.The model integrates an eight-module“China Topics”vocabulary bank,scaffolded skill training,and low-risk,high-fidelity simulation activities.A post-course survey showed significant improvements:ICC conceptual understanding rose from near zero to 87.21%high familiarity;confidence in formal debate reached 72.1%;constructive communication behaviors increased from under 20%to over 58%;and students became able to confidently introduce contemporary topics such as high-speed rail and rural revitalization.Overall course satisfaction was 89.54%,with core reform measures rated as helpful by over 90%of students.The study provides a replicable,evidence-based pathway for cultivating international communication competence in similar applied undergraduate institutions. 展开更多

Recently,the Fog-Radio Access Network(F-RAN)has gained considerable attention,because of its flexible architecture that allows rapid response to user requirements.In this paper,computational offloading in F-RAN is considered,where multiple User Equipments(UEs)offload their computational tasks to the F-RAN through fog nodes.Each UE can select one of the fog nodes to offload its task,and each fog node may serve multiple UEs.The tasks are computed by the fog nodes or further offloaded to the cloud via a capacity-limited fronhaul link.In order to compute all UEs'tasks quickly,joint optimization of UE-Fog association,radio and computation resources of F-RAN is proposed to minimize the maximum latency of all UEs.This min-max problem is formulated as a Mixed Integer Nonlinear Program(MINP).To tackle it,first,MINP is reformulated as a continuous optimization problem,and then the Majorization Minimization(MM)method is used to find a solution.The MM approach that we develop is unconventional in that each MM subproblem is solved inexactly with the same provable convergence guarantee as the exact MM,thereby reducing the complexity of MM iteration.In addition,a cooperative offloading model is considered,where the fog nodes compress-and-forward their received signals to the cloud.Under this model,a similar min-max latency optimization problem is formulated and tackled by the inexact MM.Simulation results show that the proposed algorithms outperform some offloading strategies,and that the cooperative offloading can exploit transmission diversity better than noncooperative offloading to achieve better latency performance. 展开更多

We consider testing hypotheses concerning comparing dispersions between two parameter vectors of multinomial distributions in both one-sample and two-sample cases. The comparison criterion is the concept of Schur majorization. A new dispersion index is proposed for testing the hypotheses. The corresponding test for the one-sample problem is an exact test. For the two-sample problem, the bootstrap is used to approximate the null distribution of the test statistic and the p-value. We prove that the bootstrap test is asymptotically correct and consistent. Simulation studies for the bootstrap test are reported and a real life example is presented. 展开更多
