Dynamic modulation of pressure waveforms on slurry penetration in swirl pulsating grouting: performance evaluation and fluid-mechanical mechanisms
Abstract Although dynamic pressure grouting mitigates particle clogging, the mechanisms of different pressure waveforms on slurry penetration remain elusive. This study proposes a swirl pulsating pressure grouting (SPPG) technique and establishes a three-dimensional transient two-phase flow model coupling the volume of fluid method, Realisable k−ε turbulence model, and Ergun equation.
Using text-to-speech in second language research and assessment: preliminary results from elicited imitation
Abstract Text-to-speech (TTS) is a technology widely used in second language learning and testing, for example in the case of learning material creation, pronunciation training, and speaking assessment. Such advances suggest that TTS may also hold great potential for automating performance-based measures of L2 knowledge and proficiency such as the Elicited Imitation (EI) test.
The imaging-quiescent phenotype in thrombolysed acute ischemic stroke: a diffusion-weighted MRI–based deconstruction
Abstract Background: Standard CT perfusion mismatch and hypoperfusion intensity ratio formulas are undefined when ischemic core or Tmax>6 s equals zero. Such “imaging-quiescent” patients remain uncharacterized. We quantified their prevalence and used DWI to separate CTP-undetected ischemia from DWI-negative presentations. Methods: We conducted a single-center retrospective cohort study of 188 consecutive patients receiving intravenous thrombolysis between January 2023 and October 2025.
Amine-linked heteroporous covalent organic framework for synergistic anti-infective therapy of post-traumatic osteomyelitis
Abstract The treatment of post-traumatic osteomyelitis (PTO) is impeded by bacterial biofilms and disruption of drug delivery systems in acidic lesions. Here, we develop an acid-resistant amine-linked heteroporous covalent organic framework (ARCOF) using a reductive amination strategy. This approach overcomes the insufficient chemical stability and drug delivery capacity of conventional COFs arising from the trade-off between high bond strength and crystalline reversibility.
Prediction of syncope recurrence after percutaneous closure of patent foramen ovale based on machine learning
Abstract Patent foramen ovale (PFO) has been increasingly associated with otherwise unexplained syncope, but predictors of syncope recurrence after percutaneous closure remain unclear. This study aimed to develop and internally evaluate machine-learning models for predicting post-closure syncope recurrence. We retrospectively analyzed 284 patients with PFO and otherwise unexplained syncope who underwent transcatheter closure between January 2017 and December 2023.

Spin-valley-mismatched altermagnet for giant tunneling magnetoresistance
Abstract Altermagnet-based heterojunctions have demonstrated magnetoresistive effects in experiments, however, a predictive theoretical model for non-ferromagnetic structures has remained elusive. In this work, we develop a tunneling-based spin-transport theory that explicitly incorporates the transverse-wavevector (k∥)-dependent spin polarization of an altermagnet’s transport channels, enabling the prediction of giant tunneling magnetoresistance (TMR).
Doping-induced magnetic phase transition enables all-electrical spin control in CrSBr - Nature Communications
Abstract Van der Waals antiferromagnetic semiconductors are promising platforms for energy-efficient two-dimensional spintronics. However, their intrinsic spin degeneracy and the difficulty of achieving electrical spin control pose major challenges for practical device implementation.

Dynamic Response Characteristics of Rotating and Fixed Components of the Kaplan Turbine under Low and Medium Heads
1. Introduction With the increasing scarcity of coal and oil resources, hydropower has become one of the resources that are encouraged to be developed and utilized first. The turbine is the core component of hydropower equipment that realizes the mutual conversion between fluid energy and mechanical energy. Its performance has an important impact on the rational development and utilization of hydropower and the safe, reliable and stable operation of power grids and generators [1,2].

Emergent mobility edges and intermediate phases in one-dimensional quasiperiodic plasmonic chains
Anderson localization has been widely studied in low-dimensional aperiodic electronic, photonic, and acoustic systems. However, the disorder effect in the plasmonic system, where retardation and long-range couplings interact in complex ways, remains an open question. In this work, we investigate the localization properties of one-dimensional quasiperiodic plasmonic chains using the coupled dipole method and linearized Green's function.

The best thermoelectrics revisited in the quantum limit - npj Computational Materials
Abstract The classical problem of best thermoelectrics, which was believed originally solved by Mahan and Sofo [Proc. Natl. Acad. Sci. USA 93, 7436 (1996)], is revisited and discussed in the quantum limit. We express the thermoelectric figure of merit (zT) as a functional of electronic transmission probability by the Landauer–Büttiker formalism, which is able to deal with thermoelectric transport ranging from ballistic to diffusive regimes.
