Sensible et communication.
2016
Les sensations prennent sens sur le fond identitaire du rapport à soi et aux autres. Du symbolique au sensoriel, l'inscription sociale et culturelle des situations de communication (normes, rites, codes, processus culturaliste) contribue à préfigurer un monde de sensations et d'émotions à partir d'images et de valeurs pré-existantes.Le sensible marque la passage de l'incantation à l'incarnation, du discours et des effets de langage à la mis une forme, en scène, en actes, de la communication. Cet ouvrage propose de mettre cette approche à l'épreuve, à travers des valeurs, des discours, des univers d'expérience qui, sous l'attrait du sensible et de son pouvoir de figurativité, donnent vie et …
Numerical Simulations of the Flow Field of a Submerged Hydraulic Jump over Triangular Macroroughnesses
2021
The submerged hydraulic jump is a sudden change from the supercritical to subcritical flow, specified by strong turbulence, air entrainment and energy loss. Despite recent studies, hydraulic jump characteristics in smooth and rough beds, the turbulence, the mean velocity and the flow patterns in the cavity region of a submerged hydraulic jump in the rough beds, especially in the case of triangular macroroughnesses, are not completely understood. The objective of this paper was to numerically investigate via the FLOW-3D model the effects of triangular macroroughnesses on the characteristics of submerged jump, including the longitudinal profile of streamlines, flow patterns in the cavity regi…
La segunda operación del intelecto según santo Tomás de Aquino
2013
De acuerdo con la teoría del conocimiento de santo Tomás de Aquino, el juicio se parece a un fin en el proceso intelectivo iniciado por la simple aprehensión. La segunda operación del intelecto es necesaria para conocer la verdad como adecuación “intelletus et rei” y como carácter extramental del objeto conocido con la primera operación, de manera tal que se pueda decir que el juicio es “generador” de las fronteras entre Aristóteles y el “ens ut verum” de Aquino.
Vertex corrections for positive-definite spectral functions of simple metals
2016
We present a systematic study of vertex corrections in the homogeneous electron gas at metallic densities. The vertex diagrams are built using a recently proposed positive-definite diagrammatic expansion for the spectral function. The vertex function not only provides corrections to the well known plasmon and particle-hole scatterings, but also gives rise to new physical processes such as generation of two plasmon excitations or the decay of the one-particle state into a two-particles-one-hole state. By an efficient Monte Carlo momentum integration we are able to show that the additional scattering channels are responsible for the bandwidth reduction observed in photoemission experiments on…
High-Reynolds-number turbulent cavity flow using the lattice Boltzmann method
2018
We present a boundary condition scheme for the lattice Boltzmann method that has significantly improved stability for modeling turbulent flows while maintaining excellent parallel scalability. Simulations of a three-dimensional lid-driven cavity flow are found to be stable up to the unprecedented Reynolds number $\mathrm{Re}=5\ifmmode\times\else\texttimes\fi{}{10}^{4}$ for this setup. Excellent agreement with energy balance equations, computational and experimental results are shown. We quantify rises in the production of turbulence and turbulent drag, and determine peak locations of turbulent production.
Lipid Binding Controls Dimerization of the Coat Protein p24 Transmembrane Helix
2019
Abstract Coat protein (COP) I and COP II complexes are involved in the transport of proteins between the endoplasmic reticulum and the Golgi apparatus in eukaryotic cells. The formation of COP I/II complexes at membrane surfaces is an early step in vesicle formation and is mastered by p24, a type I transmembrane protein. Oligomerization of p24 monomers was suggested to be mediated and/or stabilized via interactions within the transmembrane domain, and the p24 transmembrane helix appears to selectively bind a single sphingomyelin C18:0 molecule. Furthermore, a potential cholesterol-binding sequence has also been predicted in the p24 transmembrane domain. Thus, sphingomyelin and/or cholestero…
Regularity for nonlinear stochastic games
2015
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also be utilized in obtaining regularity and existence results for the corresponding partial differential equations. peerReviewed
The Influence of the Lotus Flower Theme on the Perception Perception of Contemporary Urban Architecture
2021
We live in the visual culture times, when images continuously and daily are transferring some information. A visual message is also an indispensable element of architecture, in the semantic layer as an aesthetic value, sometimes fulfilling a narrative function by means of a symbol, which is an international visual code. Most of the symbols, hidden in painting, sculpture, or architecture, are elements of nature. The article discusses examples of architecture whose form is based on a lotus flower. Unification of urban landscapes leads to a decrease in the value of aesthetic impressions; therefore, the unique architecture builds the unique identity of the place.

Few-body insights of multiquark exotic hadrons
2018
In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.
