Quantum sensing of noises in one and two dimensional quantum walks

Scientific Reports, 2017
Quantum walk (QW) provides a versatile platform for the realization of quantum algorithms. Due to the existence of the inevitable noises in the walk, the different quantum algorithms accommodating to different noises are demanded.

Relative Arbitrage Opportunities With Interactions Among N Investors

Mathematical Finance, EarlyView.
ABSTRACT The relative arbitrage portfolio outperforms a benchmark portfolio over a given time‐horizon with probability one. With market price of risk processes depending on the market portfolio and investors, this paper analyzes the multi‐agent optimization of relative arbitrage opportunities in the coupled system of market and wealth dynamics.

A Model of Strategic Sustainable Investment

Mathematical Finance, EarlyView.
ABSTRACT We study a problem of optimal irreversible investment and emission reduction formulated as a nonzero‐sum dynamic game between an investor with environmental preferences and a firm. The game is set in continuous‐time on an infinite‐time horizon.

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

Mathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Gate operations for superconducting qubits and non-Markovianity

Physical Review Research
While the accuracy of qubit operations has been greatly improved in the last decade, further development is demanded to achieve the ultimate goal: a fault-tolerant quantum computer that can solve real-world problems more efficiently than classical ...

Preference‐Based Representations for Collective Agency

Topics in Cognitive Science, EarlyView.
Abstract Computational accounts of learning and decision‐making in cognitive systems, and models thereof, such as reinforcement learning, typically assume that the behavior of individual agents is determined by an externally designated reward signal such that the agent's goal is the maximization of its expected accumulated reward under the state ...

An innovative modelling proposal for the blood supply chain

Vox Sanguinis, EarlyView.
Abstract Whole‐blood donation and apheresis are the only ways to obtain blood components for human use. Tools are being developed to improve the efficiency of blood donation systems by reducing waste, increasing donations and preventing shortages.

Catecholaminergic polymorphic ventricular tachycardia–linked ryanodine receptor variants exhibit domain‐specific calcium leak and calmodulin affinity properties

The Journal of Physiology, EarlyView.
Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

How AI‐Generated Feedback Hinders or Helps Learning: A Heterogeneous TNA Study of Learning Dynamics

Journal of Computer Assisted Learning, Volume 42, Issue 4, August 2026.
ABSTRACT Background Despite growing integration of generative AI in educational settings, little is known about whether and to what extent AI‐generated real‐time feedback can support first‐grade students in solving multimodal mathematical tasks. Objectives Our study aims to examine student–AI feedback dynamics from a process‐oriented perspective ...
