New shape control tools for rational Bézier curve design

Ramanantoanina, Andriamahenina ; Hormann, Kai

In: Computer aided geometric design, 2021, vol. 88, p. 11

Bézier curves are indispensable for geometric modelling and computer graphics. They have numerous favourable properties and provide the user with intuitive tools for editing the shape of a parametric polynomial curve. Even more control and flexibility can be achieved by associating a shape parameter with each control point and considering rational Bézier curves, which comes with the...

Crossover or non-crossover outcomes : tailored processing of homologous recombination intermediates

Sanchez, Aurore ; Reginato, Giordano ; Cejka, Petr

In: Current opinion in genetics & development, 2021, vol. 71, p. 39-47

DNA breaks may arise accidentally in vegetative cells or in a programmed manner in meiosis. The usage of a DNA template makes homologous recombination potentially error-free, however, recombination is not always accurate. Cells possess a remarkable capacity to tailor processing of recombination intermediates to fulfill a particular need. Vegetatively growing cells aim to maintain genome...

A refined propensity account for GRW theory

Lorenzetti, Lorenzo

In: Foundations of Physics, 2021, vol. 51, no. 2, p. 20

Spontaneous collapse theories of quantum mechanics turn the usual Schrödinger equation into a stochastic dynamical law. In particular, in this paper I will focus on the GRW theory. Two philosophical issues that can be raised about GRW concern (a) the ontology of the theory, in particular the nature of the wave function and its role within the theory, and (b) the interpretation of the objective...

Exon–Intron differential analysis reveals the role of competing endogenous RNAs in post-transcriptional regulation of translation

Munz, Nicolas ; Cascione, Luciano ; Parmigiani, Luca ; Tarantelli, Chiara ; Rinaldi, Andrea ; Cmiljanovic, Natasa ; Cmiljanovic, Vladimir ; Giugno, Rosalba ; Bertoni, Francesco ; Napoli, Sara

In: Non-coding RNA, 2021, vol. 7, no. 2, p. 13

Stressful conditions induce the cell to save energy and activate a rescue program modulated by mammalian target of rapamycin (mTOR). Along with transcriptional and translational regulation, the cell relies also on post-transcriptional modulation to quickly adapt the translation of essential proteins. MicroRNAs play an important role in the regulation of protein translation, and their...

A fast direct solver for nonlocal operators in wavelet coordinates

Harbrecht, Helmut ; Multerer, Michael

In: Journal of computational physics, 2021, vol. 428, p. 15 p

In this article, we consider fast direct solvers for nonlocal operators. The pivotal idea is to combine a wavelet representation of the system matrix, yielding a quasi- sparse matrix, with the nested dissection ordering scheme. The latter drastically reduces the fill-in during the factorization of the system matrix by means of a Cholesky decomposition or an LU decomposition, respectively. This...
