Inversion of lattice models from the observations of microscopic degrees of freedom: parameter estimation with uncertainty quantification

However, the analysis of underpinning physical models from experimentally observed microscopic degrees of freedom remains a largely unresolved issue. Expand abstract.

Four-Arm Manipulation via Feet Interfaces

This paper presents foot-interfaces specifically made for bipedal control, with a workspace suitable for two feet operation and in five degrees of freedom each. Expand abstract.

Adiabatic Elimination and Sub-space Evolution of Open Quantum Systems

Efficient descriptions of open quantum systems can be obtained by performing an adiabatic elimination of the fast degrees of freedom and formulating effective operators for the slow degrees of freedom in reduced dimensions. Expand abstract.

Challenges in assessing voxel-wise single-subject level benefits of MB acceleration

Z-transformation of the t-statics to correct for the difference in degree of freedoms suggests that sequences without MB outperform sequences with MB acceleration. Expand abstract.

Two-field mimetic gravity revisited and Hamiltonian analysis

We show that there are actually two (instead of one) scalar degrees of freedom in this model in addition to two tensor modes. Expand abstract.

Dynamics and Transport at the Threshold of Many-Body Localization

A theme common to many of these problems is that they can be understood in terms of approximately localized degrees of freedom coupled to a heat bath (or baths) consisting of thermal degrees of freedom; however, this putative bath is itself nontrivial, being either small or very slowly...

General Composite Non-Abelian Strings and Flag Manifold Sigma Models

We fully investigate the symmetry breaking patterns occurring upon creation of composite non-Abelian strings: vortex strings in non-Abelian theories where different sets of colours have different amounts of flux. Expand abstract.

Quantum liquid with strong orbital fluctuations: the case of a pyroxene family

We analyze their excitation spectrum and outline the conditions under which the orbital degrees of freedom become liberated so that the excitations become dispersive and the spectral weight shifts to energies much smaller than the exchange integral. Expand abstract.

State Space System Modelling of a Quad Copter UAV

The three degrees of freedom (3DOF) and six degrees of freedom (6DOF) quad copter state-space models are developed starting from basic Newtonian equations. Expand abstract.

Fully-resolved wave-structure interaction simulations of a submerged cylindrical point absorber with three degrees of freedom

In this paper we present a fictitious domain Brinkman penalization (FD/BP) method for simulating wave-structure interactions (WSI) of a submerged cylindrical point absorber with three free degrees of freedom (DOF). Expand abstract.
