This research and practice looks to (re) conceptualize the relations between the natural and the social, and between the biological and the cultural. Nature, culture, bodies, texts all unravel into a limitless ‘force field of differentiation’, a complex interaction of phenomena. In consequence, I have chosen to tackle and combine the exploration of nature and technology while mainly focusing on...

The effect of run-out is clearly noticed in micro-end-milling operations, while the same run-out creates negligible change at the cutting force profile of conventional end-milling operations. In this paper, the cutting force characteristics of micro-end-milling operations with tool run-out are investigated. An analytical cutting force model is developed for micro-end-milling operations with too...

A method for extracting force constants FCs from first principles is introduced. In principle, provided that forces are accurate enough, it can extract harmonic as well as anharmonic FCs up to any neighbor shell. Symmetries of the FCs as well as those of the lattice are used to reduce the number of parameters to be calculated. The results are illustrated for the case of the Lennard-Jones potent...

Multiferroic materials, which offer the possibility of manipulating the magnetic state by an electric field or vice versa, are of great current interest. In this work, we demonstrate the first observation of electrical control of antiferromagnetic domain structure in a single-phase multiferroic material at room temperature. High-resolution images of both antiferromagnetic and ferroelectric doma...

In automated assembly, before parts can be put together, they often have to be appropriately oriented and positioned. The device performing this task is generally referred to as a part feeder. A new class of devices for non-prehensile distributed manipulation, such as MEMS actuator arrays, vibrating plates, etc., provide an alternative to traditional mechanical platforms for part feeding. These...

We have recently developed some simple continuum models of static granular media which display “fragile” behaviour: they predict that the medium is unable to support certain types of infinitesimal load (which we call “incompatible” loads) without plastic rearrangement. We argue that a fragile description may be appropriate when the mechanical integrity of the medium arises adaptively, in respon...

In quantum gauge theory of gravity, the gravitational field is represented by gravitational gauge field. The field strength of gravitational gauge field has both gravitoelectric component and gravitomagnetic component. In classical level, gauge theory of gravity gives out classical Newtonian gravitational interactions in a relativistic form. Besides, it gives out gravitational Lorentz force whi...

The Open Force Field (OpenFF) Initiative develops open, reproducible force fields for atomistic molecular simulations as well automated infrastructure and systematic methodology their parametrization validation. Here we describe the extension of OpenFF to support biopolymers, enabling both small molecules biopolymers with a self-consistent field. workflow includes QCSubmit submission curation q...

A reparameterization of the torsional parameters for the glycosidic dihedral angle, chi, for the AMBER99 force field in RNA nucleosides is used to provide a modified force field, AMBER99chi. Molecular dynamics simulations of cytidine, uridine, adenosine, and guanosine in aqueous solution using the AMBER99 and AMBER99chi force fields are compared with NMR results. For each nucleoside and force f...
