In quantum metrology, nonlinear many-body interactions can enhance the precision of Hamiltonian parameter estimation to surpass the Heisenberg scaling. Here, we consider the estimation of the interaction strength in linear systems with long-range interactions and using the Kitaev chains as a case study, we establish a transition from the Heisenberg to super-Heisenberg scaling in the quantum Fisher information by varying the interaction range. We further show that quantum control can improve the prefactor of the quantum Fisher information. Our results explore the advantage of optimal quantum control and long-range interactions in many-body quantum metrology. [less ▲]

In the 13th century, the House of the Counts of Luxembourg experiences an impressive rise. In 1346, Charles IV, son of John of Luxembourg, cumulates the dignities of his predecessors: count of Luxembourg, king of Bohemia, king of the Romans and emperor. The army is a major support in this evolution. The study of the armies, the wars, the warfare, but also of the diplomatic relations of the counts of Luxembourg, we seek in this study to highlight the armies as a dynamic phenomenon which is indicative of the transformations affecting the politics of the House of Luxembourg. We must be aware that the house of Luxembourg is not just house of counts. The Luxembourg are sometimes king or emperor. Because of the accumulation of various dignities, several geographical areas must be considered: the county of Luxembourg, northern Italy, the kingdom of Bohemia, Silesia, Tyrol, Brandenburg, the kingdom of France and even Lithuania. The social and political rise of Luxembourg makes it possible to highlight the plurality or diversity as well in the wars as in the armies. Armies and wars are both the product of the transformations and mutations imposed on Luxembourg but also the cause and accelerator of the observed evolution. By providing not only real and material support, but also immaterial support like glory and fame, the armies allow the count house to be eligible for imperial dignity and thus contribute to the journey from the count house to the royal and imperial house. Through their interdependence with society, armies influence the latter. War and society, linked by the tight bond of the economy, shape each other, giving rise to the embryo of a modern state.

This work presents a software-oriented autonomy framework that enables the incremental development of high robotic autonomy. The autonomy infrastructure in space applications is often cost-driven and built for a narrow time/complexity domain. In domains like On-orbit Servicing Assembly and Manufacturing (OSAM), this prevents scalability and generalizability, motivating a more consistent approach for the incremental development of robotic autonomy. For this purpose, the problem of vision-based grasping is described as a building block for high autonomy of dexterous space robots. Subsequently, the need for a framework is highlighted to enable bottom-up development of general autonomy with vision-based grasping as the starting point. The preliminary framework presented here comprises three components. First, an autonomy level classification provides a clear description of the autonomous behavior of the system. The stack abstraction provides a general classification of the development layers. Finally, the generic execution architecture condenses the flow of translating a high-level task description into real-world sense-planact routines. Overall, this work lays down foundational elements towards development of general robotic autonomy for scalablity in space application domains like OSAM. [less ▲]

Different arguments led to supposing that the deep origin of phase transitions has to be identified with suitable topological changes of potential related submanifolds of configuration space of a physical system. An important step forward for this approach was achieved with two theorems stating that, for a wide class of physical systems, phase transitions should necessarily stem from topological changes of energy level submanifolds of the phase space. However, the sufficiency conditions are still a wide open question. In this study, a first important step forward was performed in this direction; in fact, a differential equation was worked out which describes how entropy varies as a function of total energy, and this variation is driven by the total energy dependence of a topology-related quantity of the relevant submanifolds of the phase space. Hence, general conditions can be in principle defined for topology-driven loss of differentiability of the entropy [less ▲]

The goal of this technical report is to analyse challenges and requirements related to security in the context of an evolving European HPC ecosystem, to provide selected strategies on how to address them, and to come up with a set of forward-looking recommendations. A key assumption made in this technical report is that we are in a transition period from a setup, where HPC resources are operated in a rather independent manner, to centres providing a variety of e-infrastructure services, which are not exclusively based on HPC resources and are increasingly part of federated infrastructures.

This case comment examines the decision of the tribunal in Eskosol v Italy rejecting the respondent’s jurisdictional objections based on the inapplicability of the Energy Charter Treaty to intra-EU disputes. In particular, it examines the tribunal's construction of a division between EU law and the ECT, emphasizing the separate and distinct characters of the two regimes, with the twin ambitions of making intra-EU arbitration under the ECT less objectionable from an EU law perspective while maintaining the autonomy of ECT arbitral tribunals. Whether the tribunal's first objective is feasible, however, is doubted and the extent to which intra-EU arbitration under the ECT has a future questioned. [less ▲]

Mitigating the risks associated with space system operations, especially in Low Earth Orbit, requires a holistic approach, which addresses, in particular, cybersecurity challenges, in addition to meeting the data acquisition requirements the mission needs. Space traffic management systems form no exception to this rule, but are further constrained by backward compatibility requirements that sometimes are based on decades old foundations. As a result, some space situational awareness systems continue to operate with object catalogues and data dissemination architectures that are prone to failures, not to mention adversarial actions. Proof-of-Concept papers, demonstrating this vulnerability in example attacks on space object ephemerides distribution channels have already been published and show the urgency in rethinking the way we build such high-critical infrastructure. Leveraging recent developments of distributed systems theory and concepts from multi-party consensus in limited-trust environments and in the presence of malicious actors, we designed a more secure system for orbital object ephemerides distribution, ultimately targeting at increasing the safety of satellite operations. This paper presents EphemeriShield, a distributed ephemerides storage and distribution system, aiming at maintaining safety and security guarantees in presence of active attacker or unfortunate fault. Using our EphemeriShield prototype setup, we were able to prove its ability to mask attacks and local faults that otherwise would lead to unnecessary maneuvers. Wide adoption of EphemeriShield may help satellite system operations to become safer and less vulnerable to intentionally adversarial activities, which improves the overall sustainability of space.

The link between judicial education and an efficient judiciary is, one hopes, obvious. But in order to ensure judicial independence, contemporary wisdom has it, judicial education should also be in the hands of the judiciary. Absent such control, there is a risk that judges may be indoctrinated by interested actors and their independence compromised. Some critics, however, have been sceptical about judicial control of judicial education. Judicial control of education often justified on basis of expertise as well as need to protect independence. But judges are not pedagogues (and their view of what judging does, or should, entail are often untheorized). Nor are they particularly representative of society. In addition, a danger unmitigated by judicial control of judicial education is regulatory capture, defined as ‘the result or process by which regulation, in law or application, is consistently or repeatedly directed away from the public interest and toward the interests of the regulated industry, by the intent and action of the industry itself'. Even if other voices are integrated into discussions, the danger exists that they might seek to subvert the process to privilege their interests over the general interest. Such concerns have recently been raised in England and Wales with regard to the Equal Treatment Bench Book. The paper examines the relationship between judicial education and judicial independence through the lens of this controversy. It concludes that when judicial education trespass on the independence of the individual judge is not an easy question to answer (not least because education is always about socialization) but, crucially, it is not one answered by putting judicial education in the hands of the judiciary.
