The profile maximum likelihood estimator for the location in anisotropic hyperbolic wrapped normal models is strongly consistent, asymptotically normal, and attains the Hájek-Le Cam minimax lower bound under squared geodesic loss.
FreeStory reformulates character consistency as entity-grounded feature reuse for free-form prompts, introduces FreeStoryBench, and reports stronger consistency than baselines among training-free methods.
Introduces Hell-Char, PaLit-Char and Med-Char datasets plus a similarity-weighted supervised contrastive loss and lacuna augmentation to learn diachronic embeddings for ancient Greek letterforms.
DR-Mamba performs automatic per-document domain adaptation for binarization by modeling fast detail and slow background routes with subtractive suppression in a single forward pass.
Immiscible PdIr nanoparticles show atomic-scale interdiffusion via surface atom hopping at 200°C, flattening at 300°C, interfacial Ir diffusion at 400°C, and collective mixing at 900°C, observed with 4D electron tomography.
A stereo calibration framework for RGB-TIR cameras with 625:1 resolution asymmetry uses an active OLED screen, Hessian-based corner detection, and baseline-constrained bundle adjustment to achieve 0.382 px reprojection error.
A review reframing density estimation as 'density evolution' across scales, linking kernel smoothing to heat flow, mixtures to compression, and topology to level sets, while stating three structural results on modes, Gaussian semigroups, and log-concavity.
Otsu's between-class variance correlates more strongly with SSIM and PSNR than Kapur's entropy on BSDS500 images, revealing metric-objective bias in multilevel thresholding evaluation.
Modified MLT on Hinode blue continuum images yields 70-90 km smaller median UD diameters and 12-13% fill fractions versus 17-19% for regular MLT, with nearly identical intensity histograms and spatial clustering.
A public GPU workflow for non-Fourier SENSE MRI reconstruction with sensitivity and off-resonance mapping enables fast, accurate imaging from challenging spiral trajectories.
A detection-gated YOLOv8n-U-Net pipeline extracts glottal area waveforms from high-speed endoscopy videos, achieving cross-dataset DSC of 0.745 and using area coefficient of variation to distinguish healthy from pathological cases in a 40-subject study.
A decoupled watershed-plus-EfficientNet pipeline recovers 75.95% of cells without annotations and reaches 98.36% stage classification accuracy with instance-level explainability on the NIH BBBC041 dataset.
The MPEX AI Digital Twins project reports that its two phase-I AI milestones for hot-spot control and damage assessment are on track for June 2026 demonstration.
