A statistical mechanics model for stable rings outside the Roche limit

Jack T. Dinsmore

Stellar occultations have revealed two rings around the dwarf planet Quaoar outside the Roche limit. Simulations suggest that the rings are sustained by large velocity dispersions. We present the first analytical, first-principles theory that extends the Roche limit to describe planetary rings with large velocity dispe...

Joining schools of thought on value propositions: a review and research agenda

Cristina Mele · Irene Di Bernardo · Per Skålén · Tiziana Russo Spena

The value proposition (VP) is foundational to business research, yet literature devoted to it remains fragmented, hindering the theoretical development and practical application of this key concept. To consolidate and unify the field, the current article presents an analysis of its conceptual and intellectual structure...

From patterns to prediction: detecting crop sequence and interpreting crop selection with explainable AI at field level in Denmark

Serra, João G. · Haas, Edwin · Abalos, Diego · Hvid, Søren Kolind · y 8 más

CONTEXT Crop sequences are important for sustainable agriculture, yet we know relatively little about how they recur across individual fields or which information best predicts the crop grown each year. Denmark's national field records allow both questions to be examined over time. OBJECTIVE We identified recurrent cro...

PHASE: Pauli Hierarchical Assembly on Subdivided Elements for quantum-compatible operator synthesis

Tillman Philo · Caglar Oskay

Efficiently decomposing finite element stiffness matrices into the Pauli basis is challenging due to the exponential growth of Pauli strings with problem size. A naive Pauli expansion requires $Θ(8^{\lceil \log_2 N \rceil})$ operations, where $N$ denotes the number of degrees of freedom, rendering direct decomposition...

Global theory for NLS in the weighted spaces I: finite pseudo conformal energy

Yujin Guo · Jia Shen · Changping Yang

We intend to prove that for defocusing nonlinear Schrödinger equations, solutions with finite pseudo conformal energy must be global and scatter. This fact is first proved by Bourgain when $0

The local structure of Mn2+-doped Cs2(Na1-xAgx)InCl6 compounds.

Emmanuela DI GIORGIO · Javier GAINZA MARTIN · Federico LOCARDI · Alberto MARTINELLI

The aim of the proposal is to carry out pair distribution function (PDF), XANES and EXAFS analyses on Mn-doped halide double perovskites (HDPs), in form of bulk and nanocrystals, characterised by persistent luminescent (PeL). Remarkably, PeL disappears at room temperature (RT) moving from bulk to nano-structured sample...

Ultra-sensitive determination of cyclopiazonic acid in complex food samples via competitive time-resolved luminescence immunoassays coupled to green microextraction

Miguel Ángel Merino-Sierra · Bettina Glahn-Martínez · Fernando Pradanas-González · Pablo Purohit · y 4 más

In this study, an ultra-sensitive competitive luminescence immunoassay for detecting and quantifying the mycotoxin cyclopiazonic acid (CPA) in food was developed. Analyses were conducted in 96-well plates using magnetic beads as support for a CPA-mimetic peptide, enhancing the surface area available for competition. Li...

Beyond ionotropic crosslinking: Evaluation of a novel acid-curing method for fabrication of insoluble alginate films

Eleni Kougia · Miray Buyuk · Ahmet Yemenicioğlu · Imene Chentir · y 7 más

An alternative to ionotropic (Ca2+ binding) crosslinking of alginate based on acid-curing is proposed for fabrication of water-insoluble polysaccharide films, intended for food packaging applications. Two organic (citric, acetic) and two inorganic (HCl, H2SO4) acids, applied externally on preformed sodium alginate film...
