Double Exponential Ratio Estimator of a Finite Population Variance under Extreme Values in Simple Random Sampling

open access: yesMathematics
This article presents an improved class of efficient estimators aimed at estimating the finite population variance of the study variable. These estimators are especially useful when we have information about the minimum/maximum values of the auxiliary ...

DNA Barcoding‐Enabled Tracking of Lipid Nanoparticles: Drug‐Loading‐Dependent Biodistribution and Tumor Microenvironment Targeting

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, lipid nanoparticles are tracked in vivo using DNA barcodes to determine how varying drug loadings affect their delivery behaviors in mice. A cost‐effective strategy is developed for simultaneously monitoring the biodistribution of a library of lipid nanoparticles (LNPs).

Estimation of variance components from the measurement in a geodetic network [PDF]

open access: yesActa Montanistica Slovaca, 2005
The precision of geodetic instruments used for precise measurements in geodetic networks is described by the dispersion σ2 or the standard deviation σ. Some of geodetic instruments, like electro optic range-finder and its accuracy are characteristized by

A Lower Bound on the Estimator Variance for the Sparse Linear Model

open access: yes, 2010
We study the performance of estimators of a sparse nonrandom vector based on an observation which is linearly transformed and corrupted by additive white Gaussian noise. Using the reproducing kernel Hilbert space framework, we derive a new lower bound on

Computational Modeling of Reticular Materials: The Past, the Present, and the Future

open access: yesAdvanced Materials, EarlyView.
Reticular materials are advanced materials with applications in emerging technologies. A thorough understanding of material properties at operating conditions is critical to accelerate the deployment at an industrial scale. Herein, the status of computational modeling of reticular materials is reviewed, supplemented with topical examples highlighting ...

Constrained Extended Kalman Filter for Target Tracking in Directional Sensor Networks

open access: yesInternational Journal of Distributed Sensor Networks, 2015
The target tracking problem in directional sensor networks (DSNs) is attracting increasing attention. Unlike the traditional omnidirectional sensor, a directional sensor has a special angle of view. It can offer direction information rather than just the

De Novo Design of Integrin α5β1 Modulating Proteins to Enhance Biomaterial Properties

open access: yesAdvanced Materials, EarlyView.
NeoNectins are de novo‐designed miniproteins that selectively bind and stabilize the extended open form of integrin α5β1. When grafted onto biomaterials including hydrogel and titanium, they promote cell attachment and spreading in vitro and promoting tissue integration and bone growth in animal models, demonstrating broad potential for regenerative ...
