Equilibrium and non-equilibrium furanose selection in the ribose isomerisation network

Paolo De Los Rios, Shiling Liang, Francesco Piazza, Daniel Maria Busiello

The exclusive presence of beta -D-ribofuranose in nucleic acids is still a conundrum in prebiotic chemistry, given that pyranose species are substantially more stable at equilibrium. However, a precise characterisation of the relative furanose/pyranose fra ...

Repair or Degrade: the Thermodynamic Dilemma of Cellular Protein Quality-Control

Paolo De Los Rios, Bruno Claude Daniel Fauvet, Pierre Goloubinoff, Satyam Tiwari, Mathieu Rebeaud

Life is a non-equilibrium phenomenon. Owing to their high free energy content, the macromolecules of life tend to spontaneously react with ambient oxygen and water and turn into more stable inorganic molecules. A similar thermodynamic picture applies to th ...

Non equilibrium thermodynamics of protein organization

Alberto Stefano Sassi

Three quarters of the thesis will be devoted to the discussion of non equilibrium systems. We show how certain biological systems cannot be described by standard thermodynamics. The reason is that the energy consumption due to the hydrolysis of ATP imposes ...

Chaperones convert the energy from ATP into the nonequilibrium stabilization of native proteins

Paolo De Los Rios, Alessandro Barducci, Pierre Goloubinoff, Bruno Claude Daniel Fauvet, Alberto Stefano Sassi

During and after protein translation, molecular chaperones require ATP hydrolysis to favor the native folding of their substrates and, under stress, to avoid aggregation and revert misfolding. Why do some chaperones need ATP, and what are the consequences ...

Load-Transfer Approach for Modeling the Cyclic Thermo-Mechanical Behaviour of Energy Piles

Lyesse Laloui, Melis Sütman

Energy piles are subjected to short- and long-term cyclic thermal loads due to their unique role as heat exchangers. Their response to monotonic temperature change has been investigated by various researchers from both experimental and numerical points of ...

The Bethe Free Energy Allows to Compute the Conditional Entropy of Graphical Code Instances: A Proof From the Polymer Expansion

Nicolas Macris, Marc Vuffray

The main objective of this paper is to explore the precise relationship between the Bethe free energy (or entropy) and the Shannon conditional entropy of graphical error correcting codes. The main result shows that the Bethe free energy associated with a l ...

Non-equilibrium conformational dynamics in the function of molecular chaperones

Paolo De Los Rios, Alessandro Barducci

Why do chaperones need ATP hydrolysis to help proteins reach their native, functional states? In this review, we highlight the most recent experimental and theoretical evidences suggesting that ATP hydrolysis allows molecular chaperones to escape the bound ...

Equivalences between blocks of cohomological Mackey algebras

Baptiste Thierry Pierre Rognerud

Let G be a finite group and (K, O, k) be a p-modular system “large enough”. Let R = O or k. There is a bijection between the blocks of the group algebra RG and the central primitive idempotents (the blocks) of the so-called cohomological Mackey algebra coμ ...

Parallel retrieval of correlated patterns: From Hopfield networks to Boltzmann machines

Andrea De Antoni

In this work, we first revise some extensions of the standard Hopfield model in the low storage limit, namely the correlated attractor case and the multitasking case recently introduced by the authors. The former case is based on a modification of the Hebb ...

Towards the Glass Transition in Vibrated Granular Matter

Alessandro Luigi Sellerio

Granular materials are large sets of macroscopic particles that interact solely via contact forces. The static behavior depends on the contact network and on the surface friction forces between grains; when they are set in motion (typically by vibrations) ...

On the utility of predictive chromatography to complement mass spectrometry based intact protein identification

Yury Tsybin, Hisham Ben Hamidane

The amino acid sequence determines the individual protein three-dimensional structure and its functioning in an organism. Therefore, "reading" a protein sequence and determining its changes due to mutations or post-translational modifications is one of the ...

Lagrange Equations Coupled to a Thermal Equation: Mechanics as Consequence of Thermodynamics

Sylvain Bréchet, Christian Gruber

Following the analytic approach to thermodynamics developed by Stuckelberg, we study the evolution equations of a closed thermodynamic system consisting of point particles in a fluid. We obtain a system of coupled differential equations describing the mech ...

A theoretical study of disorder and decomposition in multinary nitrides hard coatings materials

Björn Alling

The development of multinary nitrides materials has revolutionised the hard coatings industry over the last 20 years. Especially important materials systems in this matter have been TiAlN and CrAlN which shows higher hardness, better oxidation resistance a ...

A mesoscale granular model for the mechanical behavior of alloys during solidification

Michel Rappaz, Stéphane Vernède, Jonathan Dantzig

We present a two-dimensional granular model for the mechanical behavior of an ensemble of globular grains during solidification. The grain structure is produced by a Voronoi tessellation based on an array of predefined nuclei. We consider the fluid flow ca ...

Flow boiling characteristics and flow pattern visualization of refrigerant/lubricant oil mixtures

John Richard Thome

A comprehensive review of flow boiling characteristics and flow pattern visualization of refrigerant/lubricant oil mixtures is presented in this paper. First, various parameters influenced by the lubricant oil in convective boiling of refrigerants, such as ...

Introducing bulky functional lanthanide cores into thermotropic metallomesogens: a bottom-up approach

Rosario Scopelliti, Jean-Claude Bünzli, Stéphane Suarez

Basic thermodynamic considerations are used to rationalize the formation of thermotropic mesophases incorporating aromatic ligands for trivalent lanthanide metal ions (Ln). Standard flat and bent molecular interfaces, separating the central binding unit fr ...

Spin dependent thermoelectric effects in magnetic nanostructures

Santiago Serrano Guisan

The aim of this thesis work was to obtain a deeper understanding of spin-dependent transport by the study of mixed effects of heat and charge currents in magnetic nanostructures. Indeed, even thermodynamics establish a relationship between both currents, n ...
