Book review: The scramble for Citizens: Dual nationality and state competition for immigrants; David Cook Martin
No full textThe Scramble for Citizens shows us how three states (Italy, Spain and Argentina) have competed and struggled to claim a portion of the population that has moved between its borders over the past two centuries.
In a flexible, clear, and concise way, David Cook-Martin formulates a historical reconstruction of the strategies adopted by the states in order to create and maintain links with a mobile population, while allowing us to know the tactics that people have developed to respond to these competitive dynamics
Computational simulations of complex chiral magnetic structures
No full textSince the last century there has been significant progress in the research of novel magnetic materials, which has been stimulated by the development of magnetic based technologies such as information recording. In recent years, advances in imaging and microscopy techniques have allowed the experimental observation of chiral magnetic orderings in a range of materials where Dzyaloshinskii-Moriya interactions (DMI) are present. In particular, a whirling structure known as a magnetic skyrmion has become popular since it can be as small as a few nanometres in size, and its non-trivial topology provides this configuration with an extra stability and particle-like features. It has been demonstrated that these properties make a skyrmion an important candidate for a variety of potential applications, especially for storing information bits. In general, the thermal stability of magnetic structures is an engineering problem that is crucial for any real life application of a magnetic technology. Hence, recently the stability of skyrmions has started to be addressed. In this thesis we investigate, through computer simulations, chiral magnetic structures, with special emphasis on skyrmions, in different materials with DMIs. In addition, we implement a numeric algorithm called the Nudged Elastic Band Method (NEBM) to calculate transition paths and energy barriers between equilibrium states of ferromagnetic systems. The barrier scan be used to estimate the average lifetime of these states. We apply the NEBM to analyse the destruction mechanisms of a skyrmion in a thin film and we find that the lowest energy barrier is associated to the skyrmion annihilation through the boundary of the sample. Furthermore, we study hexagonally shaped ferromagnetic islands to find parameter regions, such as applied field or sample size, where different chiral configurations can be stabilised, combining energy and NEBM calculations. Our results are obtained using computer software developed at our research group in a collaborative manner and we discuss the importance of good coding and data sharing practices for computational based scientific research

Imitation Learning based Soft Robotic Grasping Control without Precise Estimation of Target Posture
No full textIn this paper, we proposed the implementation of an imitation learning algorithm to support a simplified control scheme of a grasping task for a soft gripper. For this purpose, we combined an instance segmentation algorithm, such as state of the art Mask RCNN, for the object localization in the neural network architecture. The proposed scheme is based on a combination of scene features mapping and object localization with deep learning, which supports grasping objects regardless of target object pose. As a result, the proposed system exploits soft gripper's advantages; such as compliance with the target object shape. We compare the performance of the model to the expert demonstrations use to train the imitation learning algorithm. To this end, we changed the configuration of the environment position, pose, and shape of three different target objects, in which the system shows high performance following expert trajectories. Additionally, we tested the grasping success rate in random environment configurations. © 2021 IEEE
