作者：陆善镇 Department of Mathematics Beijing Normal University

We have noticed that the theory of R. Fefferman’s entropy is very useful to L’-Fourier analysis since his work on the entropy was raised and especially his conjecture on the entropy and pointwise convergence of Fourier series was solved (see [2], when n=1; [3-4], when n>1). In this note, we shall further study some properties of the entropy. Let J denote all the functions which have finite entropies. Ref [1] has

为考察工作场所排斥问卷(WOS)在国内的适用性,以及不同性别员工在遭受工作场所排斥后的心理健康和工作满意度状况,采用中文版WOS对437名员工进行调查,结果表明:(1)9题版WOS为单维结构,信效度良好;(2)性别在工作场所排斥与心理健康、工作满意度的关系中起调节作用。由此,修订后的中文版WOS可以作为评定工作场所排斥的工具使用;女性受工作场所排斥的负面影响更大。

This study presents results on detecting neutral atomic hydrogen(H I)21 cm absorption in the spectrum of PKS PKS1413+13 at redshift z=*** observation was conducted by FAST,with a spectral resolution of10 Hz,using 10 minutes of observing *** global spectral profile is examined by modeling the absorption line using a single Gaussian function with a resolution of 10 kHz within a 2 MHz *** goal is to determine the rate of the latest cosmic acceleration by directly measuring the redshift evolution of the H I 21 cm absorption line with Hubble flow toward a common background quasar over a decade or longer time *** will serve as a detectable signal generated by the accelerated expansion of the Universe at redshift zlumn density in this DLA system is approximately equivalent to the initial observation value,considering uncertainties of the spin temperature of a spiral host *** high signal-to-noise ratio of 57,obtained at a 10 kHz resolution,strongly supports the feasibility of using the H I 21 cm absorption line in DLA systems to accurately measure the redshift drift rate at a precision level of around 10~(-10)per decade.

This paper concerns with multiple weighted norm inequalities for maximal vector-valued multilinear singular operator and maximal commutators. The Cotlar-type inequality of maximal vector-valued multilinear singular integrals operator is obtained. On the other hand, pointwise estimates for sharp maximal function of two kinds of maximal vector-valued multilinear singular integrals and maximal vector-valued commutators are also established. By the weighted estimates of a class of new variant maximal operator, Cotlar＇s inequality and the sharp maximal flmction estimates, multiple weighted strong estimates and weak estimates for maximal vector-valued singular integrals of multilinear operators and those for maximal vector-valued commutator of multilinear singular integrals are obtained.
