Optimized Calibration of Terahertz Polarimetric Imaging Systems With Imperfect Polarizers for Accurate Jones-Matrix Mapping

This paper presents an optimized in situ calibration framework for terahertz polarimetric imaging systems that models imperfect wire-grid polarizers and determines optimal rotation angles to accurately recover sample Jones matrices using a minimal set of measurements, thereby reducing systematic errors and enabling faster, reliable field-deployable imaging.

5D Spatial Brane vs 4D Temporal Quantum Multiverse: A Phenomenological Comparison of Merging-Universe Models in a Modified Friedmann Framework

This paper phenomenologically compares two merging-universe multiverse models—a 5D spatial brane scenario and a 4D temporal quantum multiverse—against multiple cosmological datasets, finding that the latter with foreign dark matter provides a better statistical fit to observations than the former, though both remain preliminary alternatives to the standard ΛCDM model.

Square-Lattice and Honeycomb Moiré Sensing, Chirality Switching, and Sequential Collagen Chirality Unlocking in Intraocular Lenses: A Multimodal Biomedical Optical Study

This study demonstrates that sequential, chirality-matched Moiré lattice illumination (specifically honeycomb followed by square patterns) can non-invasively interact with and suppress light scattering from the two-level chiral structure of collagen in intraocular lenses, suggesting a novel optical mechanism for treating vitreous floaters.

Elasticity from Extended Structural Dynamics: Stress, Strain, and Elastic Moduli as Emergent Collective Properties

This paper introduces Extended Structural Dynamics (ESD), a kinetic framework modeling constituents as spatially extended objects to derive hyperbolic-parabolic transport laws that resolve classical hydrodynamic limitations by predicting finite signal speeds, intrinsic shock regularization, and anisotropic transport, with order-of-magnitude estimates suggesting experimentally testable phenomena like Mpemba crossovers and structural shock widths.

Observation of Macroscopic Gravitational Symmetry Breaking via Extreme Radial Stress

This study reports a statistically significant, anomalous gravitational anisotropy in rapidly rotating macroscopic masses that suggests a novel coupling between internal radial stress and spacetime metrics, potentially offering a non-linear explanation for astrophysical discrepancies like pulsar braking anomalies and spacecraft flyby deviations.

The Oscillating Worldline: Symplectic Involution, Topological Mass Generation, and the Geometric Resolution of Baryon Asymmetry

This paper proposes a unified topological framework based on an Extended Equivalence Principle and symplectic involution at null boundaries to geometrically resolve the Black Hole Information Paradox, derive the Standard Model mass hierarchy and gauge parameters, and explain the Baryon Asymmetry by sequestering antimatter within stable, self-braided hadronic knot topologies.

The highest tightly bound nuclei and the stability prediction of their isobaric nuclei versus beta decay in the liquid drop model

This study extends the semi-empirical mass formula to a ten-term model and demonstrates that regional fitting of coefficients to specific nuclear datasets significantly outperforms global fitting in accurately predicting the binding energies of tightly bound nuclei and their beta-decay stability trends.

Biaxial Strain-Tunable Type-II MoS₂/WSe₂ van der Waals Heterostructures: Band Alignment Engineering and Broadband Photodetection from the Visible to the Near-Infrared

This study establishes quantitative design rules for biaxial strain-tunable MoS₂/WSe₂ van der Waals heterostructures by demonstrating that applying up to 2% tensile strain systematically reduces the bandgap and optimizes interlayer charge transfer, thereby enhancing broadband photodetector performance with peak responsivity and detectivity at 1.5% strain.
