Spin glasses: disorder, frustration, and nonequilibrium complexity

Naeimeh Tahriri · Vahid Mahdikhah · Jahanfar Abouie · Daryoosh Vashaee

Spin glasses occupy a unique place in condensed matter: they freeze collectively while remaining struc-turally disordered, and they exhibit slow, history-dependent dynamics that reflect an exceptionally rug-ged free-energy landscape. This review provides an integrated account of spin-glass physics, emphasiz-ing how mic...

Transformaciones socioecológicas en entornos turísticos emergentes: análisis geoespacial y socioperceptivo

Pascual Ayamamani Collanqui · Diana Margaret Quispe Roque · Edgar Quispe-Mamani · Eleana Catacora Salas

This study analyses the socioecological transformations in emerging tourist environments in La Convención (Cusco, Peru), integrating a multi-temporal geospatial analysis (2010–2024) of vegetation cover and a socioperceptual analysis of environmental change using a mixed-methods approach. The geospatial component used s...

Physics-informed adaptive filtering for acoustic echo cancellation

Michele Scarpiniti · Danilo Comminiello · Aurelio Uncini

This paper introduces a physics-informed adaptive filtering framework for acoustic echo cancellation (AEC). Unlike conventional adaptive algorithms that rely solely on data-driven error minimization, the proposed method incorporates physically motivated priors derived from acoustic wave propagation and room impulse res...

λ-matchability in cubic graphs

Santhosh Raghul · Nishad Kothari

A vertex $v$ of a 2-connected cubic graph $G$ is $λ$-matchable if $G$ has a spanning subgraph in which $v$ has degree three whereas every other vertex has degree one, and we let $λ(G)$ denote the number of such vertices. Clearly, $λ=0$ for bipartite graphs; ergo, we define $λ$-matchable pairs analogously, and we let $ρ...

Theoretical and experimental limitations of RoCoF estimation: A geometric approach

J. Gutiérrez-Florensa · F. Sanniti · D. Tedeschi · L. Sigrist · y 2 más

A precise estimation of the Rate of Change of Frequency (RoCoF) is crucial for secure power system operation. In fact, RoCoF is strictly related to the amount of the available physical and/or virtual inertia of the system and the severity of the active power unbalance following a disturbance. For this reason, it is wid...

Almost all cographs have a cospectral mate

Wei Wang · Ximei Huang

Complement-reducible graphs (or cographs) are the graphs formed from the single-vertex graph by the operations of complement and disjoint union. By combining the Johnson-Newman theorem on generalized cospectrality with the standard tools in the asymptotic enumeration of trees, we show that almost all cographs have a co...

In situ synchrotron-based Moessbauer spectroscopy study of selective oxidation of alcohols on Fe2(MoO4)3

Jan WELZENBACH · Lanjie JIANG · Sergey YAROSLAVTSEV · Jonas SPIELMANN · y 2 más

Since several decades, iron molybdate (Fe2(MoO4)3, noted as FMO) has been the industrial catalyst in oxidative dehydrogenation (ODH) of methanol to produce formaldehyde. In the industrial catalyst, FMO is typically prepared with an excess of molybdenum to enable good stability. The same kind of materials can be employe...

Dimensionless log-normal closure for a global volume-surface model to describe coagulation, condensation and sintering for nanoparticle flame synthesis in the free molecular regime

Franzelli, B. · Vié, A.

Computational fluid dynamics (CFD) simulations represent an essential tool for the rational design of Flame Spray Pyrolysis (FSP) systems, which are considered today as a promising technology for the large-scale production of high-value metal-oxides (MO). One of the key requirements is to obtain a particle size distrib...
