Asymptotic normality of the truncation probability estimator for truncated dependent data [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2009
In some long term studies, a series of dependent and possibly truncated life-times may be observed. Suppose that the lifetimes have a common marginal distribution function. In left-truncation model, one observes data (Xi,Ti) only, when Ti ≤ Xi.

Asymptotic Distribution of Normalized Arithmetical Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
Let f ( n ) f(n) be an arbitrary arithmetical function and let A N {A_N} and B N {B_N} be sequences of real numbers with 0 > B N

Modular, Textile‐Based Soft Robotic Grippers for Agricultural Produce Handling

open access: yesAdvanced Robotics Research, EarlyView.
This article introduces textile‐based pneumatic grippers that transform simple textiles into robust bending actuators. Detailed experiments uncover how cut geometry and fabric selection shape performance. Successful handling of fragile agricultural items showcases the potential of textile robotics for safe, scalable automation in food processing and ...

Robust Estimations for the Tail Index of Weibull-Type Distribution

open access: yesRisks, 2018
Based on suitable left-truncated or censored data, two flexible classes of M-estimations of Weibull tail coefficient are proposed with two additional parameters bounding the impact of extreme contamination.

Engineered GM1 Intersects Between Mitochondrial and Synaptic Pathways to Ameliorate ALS Pathology

open access: yesAdvanced Science, EarlyView.
Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative disease driven by genetic and molecular disruptions affecting energy balance, protein homeostasis, and stress responses in nerve cells. Studies using human and rodent models identified convergent defects in mitochondria and synaptic function.

Asymptotic Normality of Bispectral Estimates

open access: yesThe Annals of Mathematical Statistics, 1966
The work presented here is a continuation of that presented in an earlier paper, M. Rosenblatt and J. Van Ness [15], in which the basic properties (unbiasedness and consistency) of certain estimates of the bispectrum and bispectral density are discussed.

Asymptotic normality of winsorized means

open access: yesStochastic Processes and their Applications, 1988
Given independent, identically distributed random variables \(X_ 1,...,X_ n\), let \(r_ n\) and \(s_ n\) be specified integers satisfying \(1\leq r_ n, s_ n\leq n/2\). A Winsorized mean is constructed by replacing the \(s_ n\) smallest observations and the \(r_ n\) largest observations by the \(s_ n th\) smallest observation and the \(r_ n th\) largest

OPTRACE: Optical Imaging–Guided Transplantation and Tracking of Cells in the Mouse Brain

open access: yesAdvanced Science, EarlyView.
OPTRACE establishes an optical, two‐step platform for intracerebral cell therapy. Transparent glass pipettes enable real‐time, image‐guided delivery, while multiplex genetic labeling with two‐photon and bioluminescence readouts supports longitudinal single‐cell tracking and host–graft dynamics.

Mathematical Prediction for Geometry‐Mediated Cell 3D In‐Growth on Bone Tissue Engineering Scaffolds

open access: yesAdvanced Science, EarlyView.
This study identifies a fundamental pore size dependent pattern of three dimensional bone marrow derived mesenchymal stem cell (BMSC) infiltration within porous scaffolds, where small pores promote horizontal cellular bridging and large pores facilitate vertical migration.
