About the limits of inverse systems in the category S(B) of Segal topological algebras [PDF]

open access: yesProceedings of the Estonian Academy of Sciences, 2020
In this paper, we give a necessary condition for the existence of limits of all inverse systems and a sufficient condition for the existence of limits for all countable inverse systems in the category S(B) of Segal topological algebras.

Quantum teleportation with pair-coherent states [PDF]

open access: yes, 2006
Recently it has been argued that all presently performed continuous variable quantum teleportation experiments could be explained using a local hidden variable theory.

Limiting Values and Functional and Difference Equations

open access: yesMathematics, 2020
Boundary behavior of a given important function or its limit values are essential in the whole spectrum of mathematics and science. We consider some tractable cases of limit values in which either a difference of two ingredients or a difference equation ...

KdV soliton interactions: a tropical view

open access: yes, 2013
Via a "tropical limit" (Maslov dequantization), Korteweg-deVries (KdV) solitons correspond to piecewise linear graphs in two-dimensional space-time. We explore this limit.Comment: 10 pages, 4 figures, conference "Physics and Mathematics of Nonlinear ...

A quantum walk on the half line with a particular initial state

open access: yes, 2016
Quantum walks are considered to be quantum counterparts of random walks.They show us impressive probability distributions which are different from those of random walks.That fact has been precisely proved in terms of mathematics and some of the results ...

Diffusion‐based size determination of solute particles: a method adapted for postsynaptic proteins

open access: yesFEBS Open Bio, EarlyView.
We present a diffusion‐based approach for measuring the size of macromolecules and their complexes, and demonstrate its use on postsynaptic proteins. The method requires fluorescein‐labelled protein samples, a microfluidic device that maintains laminar flow for said samples, a microscope recording the emitted fluorescent signals, and an analytic ...

The Use of GeoGebra in Teaching Mathematical Concepts: Practices, Barriers, and Teachers' Perceptions

open access: yesRevista Latinoamericana de Tecnología Educativa
The use of GeoGebra in teaching mathematics has grown significantly in recent years, so this study aims to explore the use of this software by teachers in teaching the limit of a function. For this purpose, a questionnaire has been designed and validated

Overview of molecular signatures of senescence and associated resources: pros and cons

open access: yesFEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Students' conceptual understanding of limit of functions reviewed from mathematical beliefs

open access: yesJurnal Elemen
Conceptual understanding is a student’s cognitive structure characterised by the ability to transform and explain concepts in solving problems. Many students were unable to explain the concepts and the relationships between concepts in solving the limit
