Cross-fusion of digital twins and artificial intelligence in diabetes: from mechanistic elucidation to full-cycle precision management
Abstract The integration of digital twins (DT) and artificial intelligence (AI) is driving a paradigm shift in diabetes mellitus (DM) care from traditional population-based, symptomatic intervention to a lifecycle-oriented precision management approach. This review systematically elaborates on the cross-disciplinary integration mechanisms of the two technologies.

Molecular mechanisms and structure—activity relationships of natural polysaccharides in ameliorating type 2 diabetes mellitus: a comprehensive review
Abstract Type 2 diabetes mellitus (T2DM) is a global metabolic pandemic affecting hundreds of millions of people, with current pharmacological therapies limited by adverse effects, long-term tolerability issues, and cost barriers. Natural polysaccharides—high-molecular-weight carbohydrate polymers derived from plants, fungi, marine organisms, and animal sources—have emerged as a promising class of multi-target bioactive agents for T2DM management.

The Development of a Fast-Acting Cluster-Tube Self-Adaptive Robotic Hand
Submitted: 02 February 2026 You are already at the latest version Fast and universal grasping remains a critical challenge for robotic hands operating in unstructured and industrial environments. Conventional pin-array-based robotic hands exhibit strong adaptability to objects with diverse geometries, yet their grasping speed is often limited by centralized motor-driven actuation.
Investigating the Feasibility of Using Eye-Tracking Metrics as Indicators of Situation Awareness in Flight Training
Abstract Assessing pilot trainees’ Situation Awareness (SA) is critical for aviation safety and efficiency. This study aimed to evaluate the effectiveness of three distinct eye-tracking metrics, gaze-based metrics, gaze patterns, and gaze entropy, in measuring the SA levels of pilot trainees. A between-subject experiment compared two trainee groups: one received standard training, and the other received training enhanced with vibrotactile feedback.

Phase transition in magic with random quantum circuits - Nature Physics
Abstract Magic is a property of quantum states that enables universal fault-tolerant quantum computing using simple sets of gate operations. Understanding the mechanisms by which magic is created or destroyed is, therefore, a crucial step towards efficient and practical fault-tolerant computation. Many proposals for error correction in quantum computing make use of so-called stabilizer codes, which use multiqubit measurements to detect deviations from logical qubit states.
Enhancing the electron pair approximation with measurements on trapped-ion quantum computers - npj Quantum Information
Abstract The electron pair approximation offers an efficient variational quantum eigensolver (VQE) approach for chemistry simulations on quantum computers. With the number of entangling gates scaling quadratically with system size and a constant measurement overhead, the orbital optimized unitary pair coupled cluster double (oo-upCCD) ansatz strikes a balance between accuracy and efficiency. However, the electron pair approximation prevents the method from achieving quantitative accuracy.

Interactive cryptographic proofs of quantumness using mid-circuit measurements - Nature Physics
Abstract The ability to perform measurements in the middle of a quantum circuit is a powerful resource. It underlies a wide range of applications, from remote state preparation to quantum error correction. Here we apply mid-circuit measurements for a particular task: demonstrating quantum computational advantage. The goal of such a demonstration is for a quantum device to perform a computational task that is infeasible for a classical device with comparable resources.
Study on the Simulation of the EMU Body Operating Main Breaker Overvoltage and High-Voltage Side Suppression Method Based on the 3D Structure
Abstract : Current circuit simulation research on EMU (Electric Multiple Unit) overvoltage has focused on overvoltage amplitude distribution and the oscillation frequency of the operating main circuit breaker overvoltage. However, when studying the suppression method, the overvoltage amplitude and frequency characteristics must be considered simultaneously, and few studies have reported on the overvoltage frequency distribution.

The slow-evolving Acorus tatarinowii genome sheds light on ancestral monocot evolution - Nature Plants
Abstract Monocots are one of the most diverse groups of flowering plants, and tracing the evolution of their ancestral genome into modern species is essential for understanding their evolutionary success. Here, we report a high-quality assembly of the Acorus tatarinowii genome, a species that diverged early from all the other monocots. Genome-wide comparisons with a range of representative monocots characterized Acorus as a slowly evolved genome with one whole-genome duplication.

Clofazimine for Treatment of Extensively Drug-Resistant Pulmonary Tuberculosis in China
We performed a multicenter, prospective, randomized study to investigate the efficacy and safety of clofazimine (CLO) for treatment of extensively drug-resistant tuberculosis (XDR-TB) in China. Forty-nine patients infected with XDR-TB were randomly assigned to either the control group or the CLO group, both of which received 36 months of individually customized treatment. The primary endpoint was the time to sputum culture conversion on solid medium.
