Herminio: sculpture, physics and motion
Sculpture Journal, 2013 This article looks to make a philosophical reading of a number of sculptures by Herminio Alvarez (b. 1945). After briefly presenting the topic, it discusses the differences between sculpture and artifacts. Focusing on these differences, it argues for a shared problematic held by some of Herminio's sculptures and certain philosophical ideas.

Numerically "exact" approach to open quantum dynamics: The hierarchical equations of motion (HEOM).
Journal of Chemical Physics, 2020 An open quantum system refers to a system that is further coupled to a bath system consisting of surrounding radiation fields, atoms, molecules, or proteins. The bath system is typically modeled by an infinite number of harmonic oscillators.

Ontological physics-based motion planning for manipulation [PDF]
2015 IEEE 20th Conference on Emerging Technologies & Factory Automation (ETFA), 2015 Robotic manipulation involves actions where contacts occur between the robot and the objects. In this scope, the availability of physics-based engines allows motion planners to comprise dynamics between rigid bodies, which is necessary for planning this ...

Physics-based character controllers using conditional VAEs
ACM Transactions on Graphics, 2022 High-quality motion capture datasets are now publicly available, and researchers have used them to create kinematics-based controllers that can generate plausible and diverse human motions without conditioning on specific goals (i.e., a task-agnostic ...

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Interplay between one-particle and collective degrees of freedom in nuclei
, 2016 Some developments of nuclear-structure physics uniquely related to Copenhagen School are sketched based on theoretical considerations versus experimental findings and one-particle versus collective aspects.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

On the origin of the gravitational quantization: The Titius--Bode Law
, 2005 Action at distance in Newtonian physics is replaced by finite propagation speeds in classical post--Newtonian physics. As a result, the differential equations of motion in Newtonian physics are replaced by functional differential equations, where the ...

Analytical solution of the dynamical spherical MIT bag [PDF]
, 2001 We prove that when the bag surface is allowed to move radially, the equations of motion derived from the MIT bag Lagrangian with massless quarks and a spherical boundary admit only one solution, which corresponds to a bag expanding at the speed of light.
