Nonlinear space-time model reduction in the frequency domain

Peter Frame · Aaron Towne

We propose a space-time reduced-order model (ROM) for nonlinear dynamical systems, building upon previous work on linear systems. Whereas most ROMs are space-only in that they reduce only the spatial dimension of the state, the proposed method leverages an efficient encoding of the entire trajectory of the state on the...

An energy-based model of soil fragmentation by tillage

Olivier Heller · Andrea Carminati · Sara König · John Koestel · y 3 más

Tillage greatly modifies soil structure, yet existing approaches to modelling tillage-induced soil structural change remain largely qualitative or over-simplified. Here, we present a quantitative, energy-based reformulation of the classical tillage equation that predicts soil fragmentation from the initial soil state a...

Photometric characterization of near-Earth asteroids: Rotation, taxonomy, and candidate evidence for internal cohesion

Albino Carbognani · Alberto Buzzoni · Manuel Barbetta · Roberto Gualandi

We present the results of a survey of previously uncharacterized near-Earth asteroids (NEAs) conducted between the second half of 2024 and the first months of 2026 using broadband $BVR_{c} I_{c}$ photometry and time-resolved lightcurve observations. Color indices were obtained for 14 NEAs of the 15 observed, with a dim...

Efficient reconstruction of arboreal networks

Katharina T. Huber · Katherine St. John

Arboreal networks are multi-rooted phylogenetic networks whose underlying graph is a tree. We give an encoding of stack-free arboreal networks in terms of triplets and the novel concept of a duet. This yields a polynomial time algorithm to construct these networks from complete triplet and duet systems. The classificat...

Simulation of Gaussian random fields on surfaces using the isogeometric finite element method

Helmut Harbrecht · Florian Sonderegger · Remo von Rickenbach

We are concerned with the fast simulation of random fields on closed surfaces in $\mathbb{R}^3$ which are generated by the (Whittle-) Matérn class of covariance functions. To this end, we solve the underlying fractional stochastic partial differential equation with additive white noise by using an isogeometric finite e...

Mitigation of Heat Infiltration into the Building: An Experimental and Numerical Investigation on Reinforced Cement Concrete Roof Slab integrated with Nano Enhanced Phase Change Material

Rajkumar, Sundararajan · Karthick, Haridass · Nallusamy, Nallusamy · U, Rajesh Kumar

Advances in footwear and surface for prevention of occupational slips and falls - A scoping review

Lasse Jakobsen · Mathias Munk-Hansen · Filip Gertz Lysdal · Kent Jacob Nielsen · y 1 más

This scoping review synthesizes research since 2016 on footwear and surface in relation to slip and fall risks. Following the PRISMA-ScR protocol, studies were mapped to fit this scope of footwear and surface interaction from an ergonomic perspective. Key findings show advances in portable tribometers, aiming for reali...

Footprints of plastic deformation along strain gradients in twisted Au microwires

Konrad PRIKOSZOVICH · Robin FREVILLE · Patric GRUBER · Jean-Sebastien MICHA · y 1 más

This proposal involves 3D Laue microdiffraction experiments within single crystalline cross-sections of twisted Au micro wires with a bamboo microstructure using the DAXM setup at BM32. The DAXM measurements can be used to determine both, the global and local deformation (strain and misorientation fields) in 3D as well...

Paid attention: Mapping political and news advertising strategies on social media across Europe

Simon Zollo · Niccolò Di Marco · Roy Cerqueti · Walter Quattrociocchi · y 1 más

We investigate the structure and dynamics of paid visibility on social media platforms by analyzing the advertising behavior of political parties and news outlets across six European countries (France, Germany, Italy, Poland, Spain, and the United Kingdom) from 2019 to 2024. Drawing on ∼291k advertising campaigns and ∼...

Antimicrobial and antiviral effects of viscous mouthwash containing cetylpyridinium chloride and isopropyl methylphenol

Yasuhiko, Abe · Ami, Yoshioka · Maho, Takeuchi

To evaluate the antimicrobial and antiviral activities of a viscous mouthwash containing cetylpyridinium chloride (CPC) and isopropyl methylphenol (IPMP).An experimental mouthwash containing 0.05% CPC, 0.1% IPMP, and 0.3% hydroxyethyl cellulose was compared with commercially available mouthwashes. Antibacterial and fun...
