Using Geometry to Select One Dimensional Exponential Families That Are Monotone Likelihood Ratio in the Sample Space, Are Weakly Unimodal and Can Be Parametrized by a Measure of Central Tendency

open access: yesEntropy, 2014
One dimensional exponential families on finite sample spaces are studied using the geometry of the simplex Δn°-1  and that of a transformation Vn-1 of its interior.

PRC2.1 Coordinates Peri‐Nucleolar H3K27me3‐Enriched Heterochromatin Organization and NPM1 Pentamerization to Maintain Nucleolar Integrity

open access: yesAdvanced Science, EarlyView.
PRC2.1(PCL2)‐coordinated H3K27me3‐enriched PNH establishes a spatial scaffold crucial for nucleolar integrity. As a crucial coordinator, PCL2 links PRC2.1 to chromatin organization and NPM1 assembly. This network‐based model reveals how chromatin modifications and nucleolar components cooperatively maintain nucleolar architecture, revealing novel ...

TWO NEW EXPONENTIAL FAMILIES OF LORENZ CURVES [PDF]

open access: yes
We present two new Lorenz curve families by using the basic model proposed by Sarabia, Castillo and Slottje (1999). We present estimations which show that the models in our new families are very efficient when applied to data on income distribution for a

A method to construct exponential families by representation theory [PDF]

open access: yes, 2022
In this paper, we give a method to construct "good" exponential families systematically by representation theory. More precisely, we consider a homogeneous space $G/H$ as a sample space and construct an exponential family invariant under the ...

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

open access: yesAdvanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

Kernel Conditional Exponential Family

open access: yes, 2017
A nonparametric family of conditional distributions is introduced, which generalizes conditional exponential families using functional parameters in a suitable RKHS. An algorithm is provided for learning the generalized natural parameter, and consistency of the estimator is established in the well specified case.

Redox‐Dependent Chaperoning of GBF1 Condensates Regulates Seed Germination in Arabidopsis

open access: yesAdvanced Science, EarlyView.
In dormant seeds (low ROS), GBF1 forms liquid condensates to repress the germination gene CathB3, and the chaperone GIP1 maintains condensate liquidity and repressive activity. Upon imbibition (high ROS), ROS oxidize GIP1 during germination, impairing its chaperone function.

On the Fisher Metric of Conditional Probability Polytopes

open access: yesEntropy, 2014
We consider three different approaches to define natural Riemannian metrics on polytopes of stochastic matrices. First, we define a natural class of stochastic maps between these polytopes and give a metric characterization of Chentsov type in terms of ...

Traction Force Microscopy for Viscoelastic Substrates: A Semi‐Analytical Method

open access: yesAdvanced Science, EarlyView.
A semi‐analytical viscoelastic traction force microscopy framework is introduced for quantifying time‐resolved cell tractions on flat finite‐thickness substrates. The method generalizes elastic traction force microscopy to Generalized Maxwell materials, identifies when elastic approximations remain valid and, when they do not, shows that inferred ...
