Non-uniform Bound on Normal Approximation of Latin Hypercube Sampling

open access: yesJournal of Mathematics Research, 2009
Loh (Loh, W.L, 1996b) established a Berry-Esseen type bound for $W$, the random variable based on a latin hypercube sampling, to the standard normal distribution. He used an inductive approach of Stein's method to give the rate of convergence $\frac{C_d}{\sqrt{n}}$ without the value of $C_d.$ In this article, we use a concentration inequality approach ...

Robust Direction Estimation of Terrestrial Signal via Sparse Non-Uniform Array Reconfiguration under Perturbations

open access: yesRemote Sensing
DOA (Direction of Arrival), as an important observation parameter for accurately locating the Signals of Opportunity (SOP), is vital for navigation in GNSS-challenged environments and can be effectively obtained through sparse arrays.

Non-uniform Bounds and Edgeworth Expansions in Self-normalized Limit Theorems

open access: yesJournal of Theoretical Probability
Abstract We study Edgeworth expansions in limit theorems for self-normalized sums. Non-uniform bounds for expansions in the central limit theorem are established while imposing only minimal moment conditions. Within this result, we address the case of non-integer moments leading to a reduced remainder.

Knowledge Distillation with Geometry-Consistent Feature Alignment for Robust Low-Light Apple Detection

open access: yesSensors
Apple-detection performance in orchards degrades markedly under low-light conditions, where intensified noise and non-uniform exposure blur edge cues critical for precise localisation.

On Robustness for the Skolem, Positivity and Ultimate Positivity Problems [PDF]

open access: yesLogical Methods in Computer Science
The Skolem problem is a long-standing open problem in linear dynamical systems: can a linear recurrence sequence (LRS) ever reach 0 from a given initial configuration?

Emerging topological bound states in Haldane model zigzag nanoribbons

open access: yesnpj Quantum Materials
Zigzag nanoribbons hosting the Haldane Chern insulator model are considered. In this context, a reentrant topological phase, characterized by the emergence of quasi zero dimensional in-gap states, is discussed.

Reflection/refraction at the interface of an elastic solid and a partially saturated porous solid containing liquid filled bound pores and a connected pore space saturated by two-phase fluid

open access: yesLatin American Journal of Solids and Structures
The phenomena of reflection and refraction of plane waves incident obliquely at a plane interface between uniform elastic solid half-space and porous solid containing liquid filled bound pores and two-phase fluid in connected pores has been analyzed. The

Direct Position Determination of Non-Circular Sources Based on a Doppler-Extended Aperture With a Moving Coprime Array

open access: yesIEEE Access, 2018
Direct position determination (DPD) is a new promising technique in wireless location. Compared with conventional two-step localization methods, DPD achieves a higher accuracy by directly estimating the source location without computing the intermediate ...

Gamma-invariant ideals in Iwasawa algebras

open access: yes, 2008
Let kG be the completed group algebra of a uniform pro-p group G with coefficients in a field k of characteristic p. We study right ideals I in kG that are invariant under the action of another uniform pro-p group Gamma.
