COUNTRYSIDE EDUCATION AND MATHEMATICS EDUCATION: POSSIBLES INTERLACING

open access: yesReflexão & Ação, 2017
This essay reflects on the favorable conditions that are offered by the Countryside Education on the ethnomathematics experiences. The principles that underlie such education combined with its organization of time and space - Pedagogy of Alternation ...

Interlacing Log-concavity of the Boros-Moll Polynomials [PDF]

open access: yes, 2010
We introduce the notion of interlacing log-concavity of a polynomial sequence $\{P_m(x)\}_{m\geq 0}$, where $P_m(x)$ is a polynomial of degree m with positive coefficients $a_{i}(m)$.

Dynamics of interlacing peakons (and shockpeakons) in the Geng-Xue equation

open access: yes, 2016
We consider multipeakon solutions, and to some extent also multishockpeakon solutions, of a coupled two-component integrable PDE found by Geng and Xue as a generalization of Novikov's cubically nonlinear Camassa-Holm type equation. In order to make sense

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

On inverse problem for tree of Stieltjes strings

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2021
For a given metric tree and two strictly interlacing sequences of numbers there exits a distribution of point masses on the edges (which are Stieltjes strings) such that one of the sequences is the spectrum of the   spectral problem  with the Neumann ...

Weighted Interlace Polynomials [PDF]

open access: yesCombinatorics, Probability and Computing, 2009
The interlace polynomials introduced by Arratia, Bollobás and Sorkin extend to invariants of graphs with vertex weights, and these weighted interlace polynomials have several novel properties. One novel property is a version of the fundamental three-term formulathat lacks the last term.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Feasibility and Tolerability of Performing Portable MRI for Neurological Disorders in an Outpatient Neurology Clinic: A Prospective Cohort

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Accessing brain magnetic resonance imaging (MRI) can be challenging, especially for underserved patients, which may lead to disparities in neurological diagnosis. Method This mixed‐methods study enrolled adults with one of four neurological disorders: mild cognitive impairment or dementia of the Alzheimer type, multiple sclerosis ...

The Interlace [PDF]

open access: yesARQ (Santiago), 2018
Resumen: No es fácil diseñar un complejo de un poco más de 1.000 departamentos sin que parezca ‘masivo’. Mediante la superposición de 31 bloques de 6 niveles cada uno, este proyecto logra combinar la repetición con la variedad, lo que permite que la combinación de un elemento serializado se perciba como una unidad.

Note on the product of the largest and the smallest eigenvalue of a graph

open access: yesSpecial Matrices
In this note, we use eigenvalue interlacing to derive an inequality between a graph’s maximum degree and its maximum and minimum adjacency eigenvalues. The equality case is fully characterized.
