Rational points on elliptic curves [PDF]

open access: yes, 2015
The theory of elliptic curves involves a pleasing blend of algebra, geometry, analysis, and number theory. This book stresses this interplay as it develops the basic theory, thereby providing an opportunity for advanced undergraduates to appreciate the ...

Sliding look-ahead window-based real-time feedrate planning for non-uniform rational B-splines curves

open access: yesAdvances in Mechanical Engineering, 2018
This article presents an online three-axis non-uniform rational B-splines preprocessing and feedrate scheduling method with chord error, axial velocity, acceleration, and jerk limitations.

L'interpolazione razionale e la sua validità

open access: yesStatistica, 2007
The rational interpolation can be used to correct anomalous values or to add missing values in a distribution of n points. Applying this method it is possible to identify a function passing by any n given points.

Verifying Zariski density of rational points on del Pezzo surfaces of degree 1

open access: yes, 2019
Let $S$ be a del Pezzo surface of degree $1$ over a number field $k$. The main goal of this talk is to give easily verifiable sufficient conditions under which its set $S(k)$ of rational points is Zariski dense. It is well known that almost all fibers of

Rational points on circles [PDF]

open access: yes, 1998
We solve the following problem.For a given rational circle $C$ passing through the rational points $p$, $q$, $r$ and a given angle $\alpha$, compute a rational point on $C$ whose angle at $C$ differs from $\alpha$ by a value of at most $\epsilon$.In ...

Rational distances from given rational points in the plane [PDF]

open access: yes
In this paper we study sets of points in the plane with rational distances from r prescribed points P1,...,Pr. A crucial case arises for r=3, where we provide simple necessary and sufficient conditions for the density of this set in the real topology. We

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

open access: yesFEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Best Proximity Points for Generalized Proximal Weak Contractions Satisfying Rational Expression on Ordered Metric Spaces

open access: yesAbstract and Applied Analysis, 2015
We introduce a generalized proximal weak contraction of rational type for the non-self-map and proved results to ensure the existence and uniqueness of best proximity point for such mappings in the setting of partially ordered metric spaces. Further, our
