Bayesian weak lensing tomography: Reconstructing the 3D large-scale distribution of matter with a lognormal prior

open access: yes, 2017
We present a Bayesian reconstruction algorithm that infers the three-dimensional large-scale matter distribution from the weak gravitational lensing effects measured in the image shapes of galaxies.

Gel‐Amin for Improving Extracellular Recordings of Cardiomyocytes in a 3D Microphysiological System

open access: yesAdvanced Electronic Materials, EarlyView.
This work combines a conductive collagen‐based hydrogel with a laser‐cut and assembly technique to fabricate microphysiological systems that improve extracellular recordings of cardiomyocytes in 3D on microelectrode arrays. The inclusion of choline acrylate into GelMA imparts a higher electrical conductivity and improves the signal‐to‐noise ratio of on‐

Forms and genesis of species abundance distributions [PDF]

open access: yesComputational Ecology and Software, 2015
Species abundance distribution (SAD) is one of the most important metrics in community ecology. SAD curves take a hollow or hyperbolic shape in a histogram plot with many rare species and only a few common species. In general, the shape of SAD is largely

On the Existence and Uniqueness of the Maximum Likelihood Estimators of Normal and Lognormal Population Parameters with Grouped Data

open access: yesJournal of Probability and Statistics, 2009
Lognormal distribution has abundant applications in various fields. In literature, most inferences on the two parameters of the lognormal distribution are based on Type-I censored sample data.

Variability in the Log Domain and Limitations to Its Approximation by the Normal Distribution

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2020
Pharmacometric models using lognormal distributions have become commonplace in pharmacokinetic–pharmacodynamic investigations. The extent to which it can be interpreted by traditional description of variability through the normal distribution remains ...

Tsunami Distribution Functions along the Coast: Extended

open access: yesJournal of Marine Science and Engineering, 2022
The distribution of tsunami runup heights along the coast is studied both theoretically and experimentally using observation data of historical tsunami from 1992 to 2018.

Enhanced Resistive Switching Uniformity in Tantalum Oxide Memristor Devices via Copper Implantation

open access: yesAdvanced Electronic Materials, EarlyView.
Metal oxide memristor devices typically suffer from uncontrolled forming processes and limited resistive switching uniformity due to the stochastic formation of an oxygen vacancy filament. Improved resistive switching uniformity in Ta2O5 memristor is developed by Cu implantation in the switching oxide.

Research on fatigue life of steel wire ropes under impact loads based on double Pareto lognormal distribution

open access: yesAdvances in Mechanical Engineering, 2017
Fatigue damage is the most important failure mode of wire ropes, and models of cumulative fatigue damage of wire ropes under multiple impact loads have been proposed based on the principle of microdamage linear accumulation.

The Truncated Lognormal Distribution as a Luminosity Function for SWIFT-BAT Gamma-Ray Bursts

open access: yesGalaxies, 2016
The determination of the luminosity function (LF) in Gamma ray bursts (GRBs) depends on the adopted cosmology, each one characterized by its corresponding luminosity distance.
