 作者：Javier Cilleruelo , Ana Zumalacárregui 来源：[J].Mathematische Zeitschrift(IF 0.879), 2017, Vol.286 (1-2), pp.545-558 摘要：Combining previous ideas from Garaev and the first author, we prove a general theorem to estimate the number of elements of a subset A of an abelian group $$G=\mathbb {Z}_{n_1}\times \cdots \times \mathbb {Z}_{n_k}$$ lying in a k-dimensional box. In many cases, this approach allo...

In the latter case the differential part of the equation is formally selfadjoint and the nonlinearity has sublinear growth at infinity. Some upper estimate for the spectral parameter is given in this case.

We propose that current methods for analysing the raw 51Cr EDTA measurements over-simplifies the disposition of 51Cr EDTA and therefore could produce biased...

H...

These approaches are based on the combination of Hankinson’s empirically derived formula with other empirical and analytical calculations. Next to shea...

By coupling Multi-COMPAC with the parameter estimation code PEST++, the vertical hydraulic conductivity ( K v) and elastic ( S ske) and inelastic ( S skp) skeletal specific-storage values of each sub-unit can be estimated using observed long...

In particular, if the measure has the 1-annular decay property at $$x_0$$ and the metric space supports a pointwise 1-Poincaré inequality at $$x_0$$ , then the upper and lower bounds are comparable and we get a two-sided estimate for thin annuli centred at $$x_0$$ . This ge...

Forensic anthropologists are often asked to estimate a child’s age from a photograph. Previous studies have attempted to estimate the age of children from photographs using ratios of the face. Here, we propose to include body measurement ratios into age estimates. A total ...
 作者：Weisong Dong 来源：[J].Nonlinear Analysis(IF 1.64), 2020, Vol.195 摘要：Abstract(#br)In this paper we study the a priori gradient estimate for admissible solutions to the Neumann problem of fully nonlinear Hessian equations on Riemannian manifolds. We derive the interior gradient estimate for admissible solutions, and then we establish the boundary g...
