Attitudes in mathematical discovery processes:

LUMAT
This paper’s purpose is to investigate the attitude of students in mathematical discovery processes in terms of the handling of counterexamples. By understanding this attitude as a kind of scientific attitude, it consists of different aspects that become

Oscillations of Delta-like1 regulate the balance between differentiation and maintenance of muscle stem cells

Nature Communications, 2021
The cell source and dynamics of Notch ligands during the regulation of muscle stem cells is unclear. Here, the authors show that the Notch ligand Dll1 has to oscillate in order to control the balance between self-renewal and differentiation of muscle ...

Oscillations of empirical distribution functions under dependence

, 2006
We obtain an almost sure bound for oscillation rates of empirical distribution functions for stationary causal processes. For short-range dependent processes, the oscillation rate is shown to be optimal in the sense that it is as sharp as the one ...

Sequential and asynchronous processes driven by stochastic or quantum grammars and their application to genomics: a survey

, 2005
We present the formalism of sequential and asynchronous processes defined in terms of random or quantum grammars and argue that these processes have relevance in genomics. To make the article accessible to the non-mathematicians, we keep the mathematical

A Bitsadze–Samarskii-Type Problem for a Second-Kind Mixed-Type Equation in a Domain with a Horizontal Half-Strip as Its Elliptic Part

Mathematics
In the theory of mixed-type equations, there are many works in bounded domains with smooth boundaries bounded by a normal curve for first- and second-kind mixed-type equations.

On the Bahadur representation of sample quantiles for dependent sequences

, 2004
We establish the Bahadur representation of sample quantiles for linear and some widely used nonlinear processes. Local fluctuations of empirical processes are discussed. Applications to the trimmed and Winsorized means are given.

A general asymptotic scheme for inference under order restrictions

, 2006
Limit distributions for the greatest convex minorant and its derivative are considered for a general class of stochastic processes including partial sum processes and empirical processes, for independent, weakly dependent and long range dependent data ...
