Construction of optimal multi-level supersaturated designs

, 2006
A supersaturated design is a design whose run size is not large enough for estimating all the main effects. The goodness of multi-level supersaturated designs can be judged by the generalized minimum aberration criterion proposed by Xu and Wu [Ann ...

Measuring our peculiar velocity on the CMB with high-multipole off-diagonal correlations [PDF]

, 2011
Our peculiar velocity with respect to the CMB rest frame is known to induce a large dipole in the CMB. However, the motion of an observer has also the effect of distorting the anisotropies at all scales, as shown by Challinor and Van Leeuwen (2002), due ...

Indicator function and complex coding for mixed fractional factorial designs

, 2007
In a general fractional factorial design, the $n$-levels of a factor are coded by the $n$-th roots of the unity. This device allows a full generalization to mixed-level designs of the theory of the polynomial indicator function which has already been ...

Complete enumeration of two-Level orthogonal arrays of strength $d$ with $d+2$ constraints

, 2007
Enumerating nonisomorphic orthogonal arrays is an important, yet very difficult, problem. Although orthogonal arrays with a specified set of parameters have been enumerated in a number of cases, general results are extremely rare.

Influence of laser spot size at diffuser plane on the longitudinal spatial coherence function of optical coherence microscopy system

, 2019
Coherence properties and wavelength of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal to noise ratio, axial resolution, and penetration depth of the system.

The Gaussian formula and spherical aberration of the static and moving curved mirrors from Fermat's principle

, 2011
The Gaussian formula and spherical aberrations of the static and relativistic curved mirrors are analyzed using the optical path length (OPL) and Fermat's principle. The geometrical figures generated by the rotation of conic sections about their symmetry

TrAp: a Tree Approach for Fingerprinting Subclonal Tumor Composition

, 2013
Revealing the clonal composition of a single tumor is essential for identifying cell subpopulations with metastatic potential in primary tumors or with resistance to therapies in metastatic tumors.

Stokes tomography of radio pulsar magnetospheres. II. Millisecond pulsars

, 2011
The radio polarization characteristics of millisecond pulsars (MSPs) differ significantly from those of non-recycled pulsars. In particular, the position angle (PA) swings of many MSPs deviate from the S-shape predicted by the rotating vector model, even

From Point Defects in Graphene to Two-Dimensional Amorphous Carbon

, 2011
While crystalline two-dimensional materials have become an experimental reality during the past few years, an amorphous 2-D material has not been reported before.

A Rejection Principle for Sequential Tests of Multiple Hypotheses Controlling Familywise Error Rates [PDF]

, 2015
We present a unifying approach to multiple testing procedures for sequential (or streaming) data by giving sufficient conditions for a sequential multiple testing procedure to control the familywise error rate (FWER), extending to the sequential domain ...
