Seniority‐Zero Quadratic Canonical Transformation Theory
International Journal of Quantum Chemistry, Volume 126, Issue 12, June 15, 2026.We construct a unitary transformation of electronic Hamiltonians using quadratic canonical transformation theory, choosing the transformation to minimize the non‐seniority‐zero elements of the transformed Hamiltonian. This allows us to add dynamic correlation to the static correlation inherent in orbital‐optimized doubly‐occupied (seniority‐zero ...

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.Abstract Background Auto‐segmentation tools are essential in adaptive radiation therapy (ART). While evaluation typically relies on geometric metrics like Dice similarity coefficient (DSC), high scores do not always translate to clinical acceptability.

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.Abstract Background Online adaptive radiotherapy (ART) relies on cone‐beam computed tomography (CBCT) imaging for daily treatment adaptation, but CBCT's physical limitations can compromise contour delineation and dose calculation accuracy. The relationship between image quality metrics and clinical ART workflow accuracy remains unclear.

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.A new coastline formed during the 2021 eruption of La Palma quickly eroded, becoming crenellated and with pocket beaches, then retreated more gradually as resistant interiors of the lava were exposed. In contrast, a second thicker lava delta changed more gradually, highlighting the importance of lithology to coastal erosion.

Hausdorff dimension of certain sets
, 2017 In the thesis we pursue the term Hausdorff measure and dimension. Hausdorff measure is a non-negative quantity, which in a certain way distinguishes among sizes of sets.

Hausdorff and packing dimension of fibers and graphs of prevalent continuous maps
, 2016 The notions of shyness and prevalence generalize the property of being zero and full Haar measure to arbitrary (not necessarily locally compact) Polish groups.

Automated Coregistered Segmentation for Volumetric Analysis of Multiparametric Renal MRI
Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3519-3535, June 2026.ABSTRACT Purpose This study aims to develop and evaluate a fully automated deep learning‐driven postprocessing pipeline for multiparametric renal MRI, enabling accurate kidney alignment, segmentation, and quantitative feature extraction within a single efficient workflow. Methods Our method has three main stages.

, 1971 In many works on Hausdorff Measure Theory it has been the practice to place certain restrictions on the measure functions used. These restrictions usually ensure both the monotonloity and the continuity of the functions The aim of the first four chapters

Metric characterizations of upper semicontinuity
, 1979 We characterize upper semicontinuity of multifunctions in terms of upper Hausdorff semicontinuity, measure of non compactness and active boundary.

The feasibility principle in community ecology
Oikos, Volume 2026, Issue 6, June 2026.The structure and function of ecological communities emerge from interactions among populations within specific environmental contexts. Yet we still lack general principles that explain how communities assemble, which patterns we should expect, and when transitions occur across diverse settings.
