Unsupervised GAN epoch selection for biomedical data synthesis

open access: yesCurrent Directions in Biomedical Engineering, 2023
Supervised Neural Networks are used for segmentation in many biological and biomedical applications. To omit the time-consuming and tiring process of manual labeling, unsupervised Generative Adversarial Networks (GANs) can be used to synthesize labeled ...

On final stopping time problems [PDF]

open access: yes, 1975
§1. Let us consider the state equation of a dynamical system $$ \left\{ \begin{gathered}{{\dot y}_{xt}}(s) = f(s,{y_{xt}}(s))\,\,0\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } t\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } s\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } T <

Métodos no estándar en el problema de la parada óptima

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2009
We analize the optimal-stopping ploblem by the use of non standard analysis techniques. Using the non standard concept of quasi-optimal time, we prove the existence of optimal times for the problems of finite and infinite horizon .

Optimal stopping with signatures

open access: yes, 2023
We propose a new method for solving optimal stopping problems (such as American option pricing in finance) under minimal assumptions on the underlying stochastic process. We consider classic and randomized stopping times represented by linear functionals

Statistics of Infima and Stopping Times of Entropy Production and Applications to Active Molecular Processes

open access: yesPhysical Review X, 2017
We study the statistics of infima, stopping times, and passage probabilities of entropy production in nonequilibrium steady states, and we show that they are universal. We consider two examples of stopping times: first-passage times of entropy production

Coupled Price–Volume Equity Models with Auto-Induced Regime Switching

open access: yesRisks, 2023
In this work, we present a rigorous development of a model for the Price–Volume relationship of transactions introduced in 2009. For this development, we rely on the precise formulation of diffusion auto-induced regime-switching models presented in our ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

On time-inconsistent stopping problems and mixed strategy stopping times [PDF]

open access: yesStochastic Processes and their Applications, 2020
A game-theoretic framework for time-inconsistent stopping problems where the time-inconsistency is due to the consideration of a non-linear function of an expected reward is developed. A class of mixed strategy stopping times that allows the agents in the game to jointly choose the intensity function of a Cox process is introduced and motivated.
