Bidiagonal Decompositions and High‐Accuracy Computations for Newton Collocation Matrices
Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.ABSTRACT We consider a class of collocation matrices A$$ A $$ associated with the Newton basis of the space of polynomials of degree at most n$$ n $$, evaluated at a set of l+1≥n+1$$ l+1\ge n+1 $$ nodes. In the most general setting, we allow n$$ n $$ of these nodes to either coincide with or differ from those defining the Newton basis.

Learning Mechanical Vibrations with Wolfram Mathematica
Modelling in Science Education and Learning, 2015 Mechanical vibrations as subject can be found within many Engineering and Science Degrees. To achieve that the students understand the mathematics and its physical interpretation is the objective we should get as docents. In this paper we describe how to

Cooperative and Non‐Cooperative Solutions in a Dynamic Model of Forest Management
Natural Resource Modeling, Volume 39, Issue 3, August 2026.ABSTRACT This study develops a deterministic finite‐horizon bioeconomic control model linking forest biomass, biodiversity, cumulative harvesting pressure, and disturbance‐motivated expected biodiversity losses. Biodiversity is modeled as a productive state variable that feeds back into biomass growth, while cumulative harvesting pressure records the ...

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.Abstract Background Conventional CT assessment of lung lesions is based mainly on morphological features. CT values represent relative X‐ray attenuation that does not directly reflect tissue composition and/or physical density. Quantitative imaging using photon‐counting CT (PC‐CT) has the potential to provide quantitative parameters, such as effective ...

Beyond goniometry: 3D digital twinning of droplets from a single image
Droplet, Volume 5, Issue 3, July 2026.We present a method to produce physics‐informed three‐dimensional digital twins of droplets from a single image for wettability analyses. We validate the method with goniometry and demonstrate its capabilities with advancing‐receding contact angle measurements, irregularly shaped droplets, and multi‐droplet systems, indicating strong potential for in ...

Comptes Rendus. Biologies, 2005 Some principles for a current methodology for biological systems' modelling are presented. It seems possible to promote a model-centred approach of these complex systems. Among present questions, the role of mechanisms producing random or quasi-random issues is underlined, because they are implied in biological diversification and in resulting ...

Climate Warming and Ice Weakening Trigger Alpine Glacier Collapses: The Marmolada Case
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The rapid retreat of temperate mid‐latitude glaciers due to global warming causes dramatic mass loss and increases their instability. Using a synthesis of thermodynamic and mechanical laws, we constructed a three‐dimensional stability model and applied it in the analysis of the collapse of a portion of the Marmolada Glacier in northeastern ...

ChemistrySelect, Volume 11, Issue 21, 4 June 2026.Water activity (aw) was measured in eight DESs (10–90 wt% water). Strong DES–water interactions persist to ∼50 wt%, after which structure collapses toward aqueous‐like behavior. Redlich–Kister, Wilson, and COSMO‐RS models showed limited performance, whereas QSAR modeling using COSMOtherm‐derived σ‐profile descriptors significantly improved aw ...
