Torus Mandibularis [PDF]

open access: yesThe American Journal of Medicine, 2017
A 54-year-old man who presented to the clinic for a routine examination was found to have a hard swelling in the floor of mouth. The swelling was noticed at the age of ten years and had been gradually progressing over the years. However, there was no history of chewing difficulty, dysphagia, dysarthria, oral ulcers or sleep disturbances. On examination,

Rapid, tunable, and multiplexed detection of RNA using convective array PCR

open access: yesCommunications Biology, 2023
Detection of RNA targets is typically achieved through RT-qPCR or RNAseq. RT-qPCR is rapid but limited in number and complexity of targets detected, while RNAseq is high-throughput but takes multiple days.

Topological Voting Method for Image Segmentation

open access: yesJournal of Imaging, 2022
Image segmentation is one of the main problems in image processing. In order to improve the accuracy of segmentation, one often creates a number of masks (annotations) for a same image and then uses some voting methods on these masks to obtain a more ...

Geodesic bipancyclicity of the Cartesian product of graphs

open access: yesTheory and Applications of Graphs, 2022
A cycle containing a shortest path between two vertices $u$ and $v$ in a graph $G$ is called a $(u,v)$-geodesic cycle. A connected graph $G$ is geodesic 2-bipancyclic, if every pair of vertices $u,v$ of it is contained in a $(u,v)$-geodesic cycle of ...

Wielokulturowość w Europie i stanowisko Kościoła katolickiego wobec migracji

open access: yesHistoria i Polityka, 2020
Artykuł zwraca uwagę na to, iż nie wolno dyskryminować żadnego cudzoziemca ze względu na kulturę, wyznanie czy rasę. Polityka migracyjna powinna prowadzić do dialogu z przybyłymi, co wynika z prezentowanego stosunku przedstawicieli nauki, w tym filozofii,

A Note on Finite Dimensional Odd Contact Lie Superalgebra in Prime Characteristic

open access: yesAxioms, 2023
Over a field of characteristic p>3, let KO(n,n+1;t̲) denote the odd contact Lie superalgebra. In this paper, the super-biderivations of odd Contact Lie superalgebra KO(n,n+1;t̲) are studied.

Epidemic Dynamics via Wavelet Theory and Machine Learning with Applications to Covid-19

open access: yesBiology, 2020
We introduce the concept of epidemic-fitted wavelets which comprise, in particular, as special cases the number I(t) of infectious individuals at time t in classical SIR models and their derivatives.

Torus Bundles Over a Torus [PDF]

open access: yesProceedings of the American Mathematical Society, 1961
1. If a compact Lie group P acts on a completely regular topological space E then E is said to be a principal P-bundle if whenever the relation px — x holds for pCzP, x£E it follows that p = e, the identity of P. The orbit space X = E/P is called the base space and the map tt: E—>X carrying y into its orbit P-y is called the projection.
