Postmating isolation and evolutionary relationships among Fejervarya species from Lesser Sunda, Indonesia and other Asian countries revealed by crossing experiments and mtDNA Cytb sequence analyses

open access: yesEcology and Evolution, 2022
To evaluate the degree of postmating isolation and the evolutionary relationships among frog species in the genus Fejervarya from Indonesia (Lesser Sunda), Bangladesh, China, and Japan, crossing experiments and molecular phylogenetic analyses were ...

RAD sequencing of common whelk, Buccinum undatum, reveals fine‐scale population structuring in Europe and cryptic speciation within the North Atlantic

open access: yesEcology and Evolution, 2021
Buccinum undatum is a subtidal gastropod that exhibits clear spatial variation in several phenotypic shell traits (color, shape, and thickness) across its North Atlantic distribution. Studies of spatial phenotypic variation exist for the species; however,

Universal portfolios generated by rational functions [PDF]

open access: yesITM Web of Conferences, 2021
The f -divergence of Csiszar is defined for a non-negative convex function on the positive axis. A pseudo f -divergence can be defined for a convex function not satisfying the usual requirements.

High-Dimensional Analysis of f-divergence Distributionally Regularized M-estimation [PDF]

open access: yes, 2022
openIn recent years Distributionally Robust Optimization (DRO) has raised to the status of one of the most used tools for robust estimation. This because it shares some nice properties such as good out-of-sample performances and well-understood ...

Statistical Divergence and Paths Thereof to Socioeconomic Inequality and to Renewal Processes

open access: yesEntropy
This paper establishes a general framework for measuring statistical divergence. Namely, with regard to a pair of random variables that share a common range of values: quantifying the distance of the statistical distribution of one random variable from ...

Generalizations of Levinson type inequalities via new Green functions with applications to information theory

open access: yesJournal of Inequalities and Applications, 2023
In this paper, four new Green functions are used to generalize Levinson-type inequalities for the class of 3-convex functions. The f-divergence, Renyi entropy, Renyi divergence, Shannon entropy, and the Zipf–Mandelbrot law are also used to apply the main

The phylogenetic analysis of Armenian collections of medicinal tinder polypore Fomes fomentarius (Agaricomycetes, Polyporaceae)

open access: yesItalian Journal of Mycology, 2022
The medicinal tinder polypore Fomes fomentarius is widely distributed in all floristic regions of Armenia on different woody substrates. The phylogenetic analysis of Armenian collections using ITS barcoding revealed that it is taxonomically complex ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

A Phylogeographic Assessment of the Malagasy Giant Chameleons (Furcifer verrucosus and Furcifer oustaleti).

open access: yesPLoS ONE, 2016
The Malagasy giant chameleons (Furcifer oustaleti and Furcifer verrucosus) are sister species that are both broadly distributed in Madagascar, and also endemic to the island.
