Bulk and shear relaxation in glasses and highly viscous liquids

open access: yes, 2012
The ratio between the couplings of a relaxational process to compression and shear, respectively, is calculated in the Eshelby picture of structural rearrangements within a surrounding elastic matrix, assuming a constant density of stable structures in ...

The Arrival Grid: Public Space as Migrant Social Infrastructure in Central Lisbon

open access: yesThe Geographical Journal, Volume 192, Issue 1, March 2026.
Short Abstract This study examines how central urban public spaces in Lisbon function as infrastructures of arrival, mediating migrant integration in everyday life and space. Drawing on ethnographic fieldwork with a spatial insight at Martim Moniz Square and Benformoso Street, the paper introduces the concept of the arrival grid as a socio‐spatial ...

L’Inter-Azione “Insegnamento-Apprendimento” Tra autoreferenzialità, neurofenomenologia, esperienza cosciente e conoscenza

open access: yesFormazione & Insegnamento, 2014
Con l’avvento della scienza della complessità, si è originato un nuovo modo di ragionare, che pone le dimensioni della logica e del tempo al centro di interessi filosofici e speculativi e, nello specifico, ha condotto a una diversa interpretazione del ...

Relaxation of Chemical Reactions to Stationary States in the Chemical Affinities Space

open access: yes, 2010
Using the mass balance equations for chemical reactions, we show how the system relaxes towards a steady state in and out of the Onsager region. In the chemical affinities space, after fast transients, the relaxation process is a straight line when ...

The Logistic Function in Glass Transition Models of Amorphous Polymers: II. A Theoretical Framework for Isothermal Compression Processes

open access: yesMacromolecular Theory and Simulations, Volume 34, Issue 6, November 2025.
An exactly‐solvable Riccati equation that approximates the macroscopic‐phenomenological behavior of amorphous polymers at glass transition pressure, Pg${P}_{g}$, is derived within thermodynamics with internal state variables. This work confirms the validity of the logistic function in glass transition models of amorphous polymers and establishes a ...

Reference Distribution Functions for Magnetically Confined Plasmas from the Minimum Entropy Production Theorem and the MaxEnt Principle, subject to the Scale-Invariant Restrictions

open access: yes, 2013
We derive the expression of the reference distribution function for magnetically confined plasmas far from the thermodynamic equilibrium. The local equilibrium state is fixed by imposing the minimum entropy production theorem and the maximum entropy ...

Physicochemical Constraints on the Abiotic Polymerization of Nucleotides Into RNA

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 11, November 2025.
Abstract One of the key steps in the origin of life is the polymerization of nucleotides into nucleic acids like RNA. We have quantified the energetic impact of temperature, pressure, and composition on the polymerization of nucleotides into RNA using the Gibbs function. These Gibbs energies have been used to calculate the probability that a nucleotide

Kinetic formulation of irreversible evolution of the two-nucleus spin systems

open access: yes, 2010
The time irreversible evolution of the two-nucleus spin systems interacting with a magnetic field is analyzed in the framework of the subdynamics theory. The spin systems are determined by the H(1) and C(13) nuclei.

Beyond Simplification in Public Sector Accountability: Contradictions Between Principal‐Agent and Complexity Theories

open access: yesPublic Administration Review, Volume 85, Issue 6, Page 1757-1770, November/December 2025.
ABSTRACT This conceptual study explores the complexity of public sector accountability, traditionally framed by principal‐agent theory (PAT), which simplifies relationships through rigid contracts. The findings reveal how PAT's assumptions often misalign with the intricate realities of public sector accountability, which are better explained by ...
