Modeling Financial System with Interbank Flows, Borrowing, and Investing
Risks, 2018 In our model, private actors with interbank cash flows similar to, but more general than that by Carmona et al. (2013) borrow from the non-banking financial sector at a certain interest rate, controlled by the central bank, and invest in risky assets ...

Semi-infinite Stochastic Games [PDF]
, 1991 We investigate two-person zero-sum stopping stochastic games with a finite number of states, for which the action sets of player i are finite and those for player ii are countably infinite. Concerning the payoffs no restrictions are made. We show that for such games the value, possibly —∞ in some coordinates, exists; player i possesses optimal ...

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Advanced Science, EarlyView.In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Multimodal Imaging Reveals Rapid Catecholamine Uptake and Release by Neutrophils
Advanced Science, EarlyView.We show that immune cells (neutrophils) synthesize, uptake, and store catecholamine neurotransmitters such as dopamine or adrenaline. They also release them in response to specific stimuli (serotonin), which we directly visualize using fluorescent nanosensors. We further demonstrate that catecholamines affect neutrophil functions (NETosis) and platelet

Q-Learning Based Physical-Layer Secure Game Against Multiagent Attacks
IEEE Access, 2019 In this paper, we consider a Q-learning-based power allocation strategy for a secure physical-layer system under dynamic radio environments. In such a system, the transmitter sends the information to the receiver threatened by M(M ≥ 2) intelligent

Spike-based decision learning of Nash equilibria in two-player games. [PDF]
PLoS Computational Biology, 2012 Humans and animals face decision tasks in an uncertain multi-agent environment where an agent's strategy may change in time due to the co-adaptation of others strategies.

Advanced Science, EarlyView.Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,

Stationary Bayesian–Markov Equilibria in Bayesian Stochastic Games with Periodic Revelation
GamesI consider a class of dynamic Bayesian games in which types evolve stochastically according to a first-order Markov process on a continuous type space. Types are privately informed, but they become public together with actions when payoffs are obtained ...
