COVID-19 and the kidney: A retrospective analysis of 37 critically ill patients using machine learning.

open access: yesPLoS ONE, 2021
IntroductionThere is evidence that SARS-CoV2 has a particular affinity for kidney tissue and is often associated with kidney failure.MethodsWe assessed whether proteinuria can be predictive of kidney failure, the development of chronic kidney disease ...

Bacterial genotyping by 16S rRNA mass cataloging

open access: yesBMC Bioinformatics, 2006
Background It has recently been demonstrated that organism identifications can be recovered from mass spectra using various methods including base-specific fragmentation of nucleic acids.

Dimensions of random affine code tree fractals [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2013
AbstractWe study the dimension of code tree fractals, a class of fractals generated by a set of iterated function systems. We first consider deterministic affine code tree fractals, extending to the code tree fractal setting the classical result of Falconer and Solomyak on the Hausdorff dimension of self-affine fractals generated by a single iterated ...

Chinese “Dialects” and European “Languages”: A Comparison of Lexico-Phonetic and Syntactic Distances

open access: yesLanguages
In this article, we tested some specific claims made in the literature on relative distances among European languages and among Chinese dialects, suggesting that some language varieties within the Sinitic family traditionally called dialects are, in fact,

Evaluation of piecewise affine control via binary search tree [PDF]

open access: yesAutomatica, 2003
An algorithm is presented for generating a binary search tree in order to compute piecewise affine functions on a piecewise polyhedral set. Applications to some control problems are indicated.

Graft Incompatibility Influence on Assimilating Pigments and Soluble Sugars Amount of some Pear (Pyrus sativa) Cultivars

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2010
Graft incompatibility in fruit trees is one of the greatest obstacles in rootstocks and cultivars breeding. The mechanism in which incompatibility is expressed is not yet fully understood and several hypotheses have been advanced in an attempt to explain

Computational Model Reveals a Stochastic Mechanism behind Germinal Center Clonal Bursts

open access: yesCells, 2020
Germinal centers (GCs) are specialized compartments within the secondary lymphoid organs where B cells proliferate, differentiate, and mutate their antibody genes in response to the presence of foreign antigens.

Random affine code tree fractals and Falconer–Sloan condition [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2014
We calculate the almost sure dimension for a general class of random affine code tree fractals in $\mathbb{R}^{d}$. The result is based on a probabilistic version of the Falconer–Sloan condition $C(s)$ introduced in Falconer and Sloan [Continuity of subadditive pressure for self-affine sets. Real Anal. Exchange 34 (2009), 413–427].

Benchmarking Tree and Ancestral Sequence Inference for B Cell Receptor Sequences

open access: yesFrontiers in Immunology, 2018
B cell receptor sequences evolve during affinity maturation according to a Darwinian process of mutation and selection. Phylogenetic tools are used extensively to reconstruct ancestral sequences and phylogenetic trees from affinity-matured sequences.
