The orthogonal Latin hypercube design and its relaxation,and column-orthogonal design,are two kinds of orthogonal designs for computer experiments.However,they usually do not achieve maximum stratifi-cations in multi-dimensional margins.In this paper,we propose some methods to construct column-orthogonal designs with multi-dimensional stratifications by rotating symmetric and asymmetric orthogonal arrays.The newly constructed column-orthogonal designs ensure that the estimates of all linear effects are uncorrelated with each other and even uncorrelated with the estimates of all second-order effects (quadratic effects and bi-linear effects) when the rotated orthogonal arrays have strength larger than two.Besides orthogonality,the resulting designs also preserve better space-filling properties than those constructed by using the existing meth-ods.In addition,we provide a method to construct a new class of orthogonal Latin hypercube designs with multi-dimensional stratifications by rotating regular factorial designs.Some newly constructed orthogonal Latin hypercube designs are tabulated for practical use.

We prove that if a compact Riemannian 4-manifold with positive sectional curvature satisfies a strengthened Kato type inequality,then it is definite.We also discuss some new insights for compact Riemannian 4-manifolds with positive sectional curvature.
Associated with a Clifford system on R2l,a Spin(m+1)action is induced on R2l.An isoparametric hypersurface N in S2l-1 of OT-FKM(Ozeki,Takeuchi,Ferus,Karcher and Münzner)type is invariant under this action,and so is the Cartan-Münzner polynomial F(x).This
In this paper we study the Lp dual Minkowski problem for the case p<0<q.We prove for any positive smooth function f on S1,there exists an F:R+→ R-,such that if F(q)<p<0 or 0<q<-F(-p)then there is a smooth and strictly convex body solving the planar Lp dua
The notion of the Ricci curvature is defined for sprays on a manifold.With a volume form on a manifold,every spray can be deformed to a projective spray.The Ricci curvature of a projective spray is called the projective Ricci curvature.In this paper,we in
In this paper,we consider the problem of the nonnegative scalar curvature(NNSC)-cobordism of Bartnik data(Σn-11,γ1,Hi)and(Σn-12,γ2,H2).We prove that given two metrics γ1 and γ2 on Sn-1(3≤n≤7)with H1 fixed,then(Sn-1,γ1,H1)and(Sn-1,γ2,H2)admit no NNSC-cobor
The Christoffel problem is equivalent to the existence of convex solutions to the Laplace equation on the unit sphere Sn.Necessary and sufficient conditions have been found by Firey(1967)and Berg(1969),by using the Green function of the Laplacian on the s
Motivated by our previous work on Hodge-index type theorems,we give a form of mixed Hodge-Riemann bilinear relation by using the notion of m-positivity,whose proof is an adaptation of the works of Timorin(1998)and Dinh and Nguyên(2006).This mixed Hodge-Ri
Motivated by the study of coupled K?hler-Einstein metrics by Hultgren and Witt Nystr?m(2018)and coupled K(a)hler-Ricci solitons by Hultgren(2017),we study in this paper coupled Sasaki-Einstein metrics and coupled Sasaki-Ricci solitons.We first show an iso
This study proposes two different methods of photocatalytic-controlled and visible light-induced selective oxidation of pyr-idiniums with air as the terminal oxidant.The key to these transformations is to choose the appropriate light source and photocatal
Excessive consumption of fossil fuels has led to an un-precedented increase of carbon dioxide (CO2) emission and triggered a series of environment issues and energy crisis [1].Converting CO2 into hydrocarbon fuels has been regarded as an effective approac
