Toward Solution‐Time Advantage With Error‐Mitigated Quantum Annealing for Combinatorial Optimization

Advanced Physics Research, EarlyView.
This paper presents a novel error mitigation technique to address the qubit errors that occur when solving combinatorial optimization problems with quantum annealing. The approach significantly speeds up the computation to reach the global optimum solution for a correlated 3D image segmentation model for material microstructures, demonstrating a ...

Dietary Baicalin Supplementation Can Enhance the Growth Performance of Weaned Piglets and Maintain the Intestinal Barrier Integrity

Animal Research and One Health, EarlyView.
This research innovatively illustrates baicalin’s multifaceted mechanisms in enhancing piglets’ intestinal health: modulating bile acid metabolism via probiotics, reinforcing tight junction proteins (ZO‐1/claudin), suppressing TLR4/NF‐κB‐mediated inflammation, whereas promoting growth and reducing diarrhea.

Risk‐aware safe reinforcement learning for control of stochastic linear systems

Asian Journal of Control, EarlyView.
Abstract This paper presents a risk‐aware safe reinforcement learning (RL) control design for stochastic discrete‐time linear systems. Rather than using a safety certifier to myopically intervene with the RL controller, a risk‐informed safe controller is also learned besides the RL controller, and the RL and safe controllers are combined together ...

Performance improvement of discrete‐time linear‐quadratic regulators applied to uncertain linear systems using the Tikhonov regularization method

Asian Journal of Control, EarlyView.
Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Change Trajectories During Parent–Child Interaction Therapy for Autistic Children and Their Caregivers

Autism Research, EarlyView.
ABSTRACT Disruptive behaviors (non‐compliance, aggression) are common in autistic children. Parent–Child Interaction Therapy (PCIT) is a caregiver‐mediated intervention utilizing in vivo caregiver coaching that reduces disruptive behaviors and has been shown to be effective for young autistic children.

Emerging research directions in nanoparticle‐based foam control for bioprocessing: a bibliometric approach

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Overfoaming remains a critical challenge in industrial bioprocesses, compromising mass transfer, operational stability, and downstream efficiency in bioreactors and wastewater treatment systems. This study provides a bibliometric and scientometric assessment of nanoparticle‐enabled foam control to map technological trends and identify research
