In this paper, we study a non-zero-sum game with two players, where each of the players plays what we call Bermudan strategies and optimizes a general non-linear assessment functional of the pay-off. By using a recursive construction, we show that th

Betulinic acid (BA) is a natural pentacyclic triterpenoid with significant pharmaceutical potential. We found that converting BA into amino acid ethyl ester salts alters its cytotoxic effect on colorectal adenocarcinoma cells (HT-29). Among these sal

Background: In the last two decades, tyrosine kinase inhibitors (TKIs) and advances in molecular diagnostics have revolutionized management and long-term clinical outcomes in chronic myeloid leukemia (CML). Real-world data from different countries al

We experimentally investigate the nonlinear dynamics of ultrashort laser pulses propagating in gas-filled hollow capillary fibres in different dispersion regimes, which are achieved by tuning the gas pressure. When the pulse propagates in the anomalo

We address an optimal stopping problem over the set of Bermudan-type strategies $\Theta$ (which we understand in a more general sense than the stopping strategies for Bermudan options in finance) and with non-linear operators (non-linear evaluations)

The role of the IL-12 family cytokines in brain tumourigenesis is an active area of research, but only a few studies have explored the impact of the functional IL12B polymorphisms on brain tumour (BT) risk. The present study aimed to evaluate the pos

In this paper, we address the stochastic representation problem in discrete time under (non-linear) g-expectation. We establish existence and uniqueness of the solution, as well as a characterization of the solution. As an application, we investigate
