Propagation dynamics of an acid-mediated invasion model with degenerate tumor diffusion

Xinyue Cao · Quentin Griette · Xiong Li · Yang Wang

We investigate traveling wave fronts for an acid-mediated tumor invasion model with density-dependent degenerate diffusion. The model is a partially diffusive PDE--ODE system of Gatenby--Gawlinski type, in which the tumor diffusion coefficient $D(U)$ is allowed to be a general decreasing function satisfying $D(1)=0$. T...

Macroscopic and microscopic study of tongue papillae in Rahmani sheep (Ovis aries): Morphometric analysis, light and scanning electron microscopic study

Fatma A. Madkour · Catrin S. Rutland · Soha A. Soliman · Madeha Ahmed · y 3 más

The tongue and papillae are vital structures for evaluating texture, taste and quality of food, yet little is known about these structures in Rahmani sheep (Ovis aries). Nine mature male tongues underwent gross inspection and morphometric analysis. Scanning electron microscopy (SEM) and light microscopy following hemat...

Monotone classification with relative approximations

Yufei Tao 0001

In monotone classification, the input is a multi-set $P$ of points in $\mathbb{R}^d$, each associated with a hidden label from $\{-1, 1\}$. The goal is to identify a monotone function $h$, which acts as a classifier, mapping from $\mathbb{R}^d$ to $\{-1, 1\}$ with a small {\em error}, measured as the number of points $...

On a conjecture about Schauder-basis properties of the Daubechies wavelet packets

Morten Nielsen

Nielsen and Zhou (\emph{Mean size of wavelet packets}, ACHA 13 (2002), 22--34) conjectured that for every Daubechies filter of length at least four the associated wavelet packets fail to be a Schauder basis of $L^p(\mathbb{R})$ for every $p\neq2$; their own $\ell^1/\ell^\infty$ estimate only reaches extreme exponents....

Challenging proteomic identification of animal species in historical leather from Japanese Samurai armors

Elena C.L. Rigante · Cristina Corti · Ludovico Geminiani · Laura Rampazzi · y 4 más

This study reports a proteomic investigation of historical leather from four Japanese Samurai armors (16th-20th century) from the Morigi Collection (Lugano, Switzerland), with the aim of identifying the animal species used and gaining insight into historical craftsmanship, material selection, and later restoration prac...

Orderable Thompson-like groups arising from Ore categories

Perego, Davide · Tarocchi, Matteo

We give sufficient conditions for left- and bi-orderability of fundamental groups of Ore categories in terms of indirect factors, including Thompson groups and many of their generalizations. Besides recovering known results, we prove that braided groups of fractions of digit rewriting systems (which generalize braided...

Target quantification and ion mobility-HRMS suspect screening of BPA and its alternatives in human urine

Riccardo De Santo · Lucia Coppola · Fabiola Ferri · Cinzia La Rocca · y 1 más

Bisphenol A (BPA) and its structural alternatives are contaminants of concern due to their endocrine-disrupting properties and widespread human exposure. The progressive replacement of BPA by alternative bisphenols has increased the need for sensitive analytical methods capable of monitoring both regulated and emerging...

An automated 1D 1H and 2D 1H-13C HSQC NMR platform for high-field (900 MHz) metabolite profiling of cerebrospinal fluid

Wuyart, Alexis · Martinez, Agathe · Cantrelle, François-Xavier · Lameiras, Pedro · y 2 más

NMR spectra from cerebrospinal fluid (CSF) samples (n = 25) were acquired using a high-field spectrometer at 900 MHz. The digital platform BioMetIQ was developed for 1D 1H and 2D 1H-13C HSQC experiments to characterize the metabolome in biofluids. To identify and quantify metabolites, the platform integrates an adaptiv...

Bis(monoacylglycero)phosphate (BMP) as a circulating biomarker of lysosomal dysfunction in GNE myopathy

Manis, Cristina · Pertusati, Fabrizio · Morewood, James · Roos, Andreas · y 9 más

GNE myopathy (GNEM) is a rare neuromuscular disorder caused by pathogenic variants in the GNE gene and traditionally associated with impaired sialic acid biosynthesis. In a previous untargeted lipidomic study, we identified a lipid feature significantly enriched in the serum of patients with GNE myopathy compared with...

Role of PICK1 in prostate cancer: Modulating epithelial-mesenchymal transition and immune escape through activation of UNC5A

Min, Wei · Shuangshuang, Zheng · Zehao, Wang · Kaige, Sheng · y 3 más

Unc-5 netrin receptor A (UNC5A) activated by protein interacting with C kinase 1 (PICK1) serves as therapeutic target to mitigate the malignant development of prostate cancer (PC). Herein, the mechanism of PICK1/UNC5A axis in PC disease is further investigated.Cell functional tests (CCK-8 and Transwell assay) were perf...
