Testing Composite Null Hypothesis Based on $S$-Divergences

open access: yes, 2015
We present a robust test for composite null hypothesis based on the general $S$-divergence family. This requires a non-trivial extension of the results of Ghosh et al.~(2015).

Design and Prototyping of Topology‐Optimized, Additively Manufactured Lightweight Components for Space Robotic Systems: A Case Study

open access: yesAdvanced Engineering Materials, EarlyView.
The results demonstrate a simulation‐driven workflow that applies LSB topology optimization with additive manufacturing constraints to mission‐specific load cases, integrating European Cooperation for Space Standardization compliant verification and manufacturability to develop structurally efficient rover suspension components.

On large-sample estimation and testing via quadratic inference functions for correlated data [PDF]

open access: yes, 2005
Hansen (1982) proposed a class of "generalized method of moments" (GMMs) for estimating a vector of regression parameters from a set of score functions.

Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

open access: yesAdvanced Engineering Materials, EarlyView.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

An elliptic boundary problem acting on generalized Sobolev spaces

open access: yes, 2017
We consider an elliptic boundary problem over a bounded region $\Omega$ in $\mathbb{R}^n$ and acting on the generalized Sobolev space $W^{0,\chi}_p(\Omega)$ for $1 < p < \infty$.

Revisiting the Null Subject Parameter

open access: yes, 2017
With the advent of the Minimalist Program (Chomsky 1995), the prevailing view of linguistic variation and contrast within universal Grammar has undergone a shift from rigidly defined parameters ˗associated with clusters of properties (Chomsky 1981; Chomsky & Lasnik 1993)˗ to an approach in which features play a central role, are flexibly distributed ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

The validity and power of extreme sampling schemes for mediation analysis

open access: yesFrontiers in Genetics, 2011
Several authors have acknowledged that testing mediational hypotheses between treatments, genes, physiological measures and behaviors may substantially advance our understanding of how these associations operate.

Estimating the causal effect of a time-varying treatment on time-to-event using structural nested failure time models

open access: yes, 2003
In this paper we review an approach to estimating the causal effect of a time-varying treatment on time to some event of interest. This approach is designed for the situation where the treatment may have been repeatedly adapted to patient characteristics,

Quantum Emitters in Hexagonal Boron Nitride: Principles, Engineering and Applications

open access: yesAdvanced Functional Materials, EarlyView.
Quantum emitters in hexagonal boron nitride have emerged as a promising candidate for quantum information science. This review examines the fundamentals of these quantum emitters, including their level structures, defect engineering, and their possible chemical structures.
