This paper defends the view that the limits of compromise are identical with the moral principles that set limits to human action more generally. Moral principles that prohibit lying, stealing, or killing, for example, sometimes make it morally impermissible to accept a compromise proposal, for the simple reason that the proposal involves an act of lying, killing, or stealing. The same holds for any other moral principle that sets limits to human action. This may sound straightforward and, perhaps, trivial. Yet in the philosophical literature, discussions of the limits of compromise have singled out more specific principles: Avishai Margalit proposes that the limits of compromise are set by the value of humanity, Simon May points at racial equality and more generally democratic legitimacy, Alexander Ruser and Amanda Machin appeal to the value of integrity, and a fourth at least initially plausible account invokes the idea of public justifiability. After discussing in greater detail what an account of the limits of compromise may be expected to do, the paper will show that none of these accounts is convincing. [ABSTRACT FROM AUTHOR]

After the parliamentary elections in Germany in September 2017, the Christian Democratic Union (CDU), the Christian Social Union (CSU), The Greens (Bündnis90/Die Grünen) and the Free Democratic Party (FDP) started to negotiate about forming a coalition government. But, surprising to many, the FDP decided to let these coalition talks collapse, and many commentators in Germany found it highly problematic for a political party to refuse to take responsibility in government. Interestingly, the question whether (or: when) democratic parties may legitimately refuse to govern has so far been neglected in political theory and political philosophy. The article develops a general answer by discussing several possible reasons for thinking that it is sometimes wrong to refuse to govern and thereby engages both democratic theory and the recent literature on compromise. The resulting view is that parties have an 'integrity prerogative' that allows them to refuse to govern, except when there is no reasonable and stable alternative government coalition available.

The working distance is an essential parameter of the laser metal deposition (LMD) process which has to be kept at a constant level for successful applications. Especially when applying LMD in additive manufacturing (AM) to generate large-scale components, distance control is crucial as these parts can take multiple hours to complete. If over time the working distance runs out of the processing limits, the process efficiency will decrease, and this can lead to a process break down destroying the component build. The development approach is to integrate an enhanced distance measurement system based on optical coherence tomography (OCT) into a commercial LMD powder processing head. By deflecting an elliptic measuring track around the processing area, the OCT system can detect the working distance as well as topological information (2D + d) compared to a standard 1D distance measurement (1D + d). By continuously collecting data when moving the processing head, a 3D-scan of the surface can be recorded online. This technology is beneficial for AM as well as LMD repair applications as the system allows the scanning of unknown surfaces prior to LMD processing. In a next development step, the position data of the laser-cell (robot or CNC-Machine) is linked to the 2D + d data gaining full 3D information with high spatial and temporal resolution in real-time. Based on these monitoring capabilities, a closed loop control can be set up by implementing stabilization methods. By adapting LMD process parameters like the powder feed rate or the processing speed, a work distance and LMD track height control can be achieved. [ABSTRACT FROM AUTHOR]

Lockeans regard taxation as a—perhaps sometimes permissible—infringement of moral property entitlements. This essay discusses whether, or in what form, this charge is defensible. In doing so, it will explore the truth and the limits of the conventionalist reply of Murphy and Nagel to Lockean challenges to taxation. It argues that there is a moral rationale for property conventions that is independent of the question whether and how one can acquire natural, pre-conventional property rights in the state of nature, that this rationale sets a moral standard for how good property conventions are and whether they are justifiable at all, and that once property conventions are in place, people's moral property entitlements are at least partly determined by these conventions, sometimes even by unjustifiable ones that ought to be reformed. Because taxation can be a part of property conventions, taxation as such is not an infringement of moral property entitlements. But the essay will also argue that some taxation—excessive taxation—does infringe on moral property entitlements. This is because the moral rationale for property conventions sets some standards for what owners should be entitled to, and so excessive taxation will infringe upon moral entitlements that are partly not convention-based.

In the last ten or fifteen years, realism has emerged as a distinct approach in political theory. Realists are skeptical about the merits of abstract theories of justice. They regard peace, order, and stability as the primary goals of politics. One of the more concrete aims of realists is to develop a realist perspective on legitimacy. I argue that realist accounts of legitimacy are unconvincing, because they do not solve what I call the "puzzle of legitimacy": the puzzle of how some persons can have the right to rule over others, given that all persons are equals. I focus on the realist accounts of legitimacy developed by Bernard Williams and John Horton. [ABSTRACT FROM AUTHOR]

From a left-libertarian perspective, it seems almost impossible for states to acquire political authority. For that reason, left-libertarians like Peter Vallentyne understandably hope that states without political authority could nonetheless implement left-libertarian justice. Vallentyne has argued that one can indeed assess a state's justness without assessing its political authority. Against Vallentyne, I try to show that states without political authority have to be judged unjust even if they successfully promote justice. The reason is that institutions can be unjust independently from what they achieve or do: they can be 'intrinsically unjust'. Institutions, I argue, are intrinsically unjust when they have legal liberties and powers without having the corresponding moral liberties and powers. States without political authority are intrinsically unjust in that sense. Hence the issues of a state's justness and a state's political authority cannot be dealt with separately. This is a problem not only for left-libertarians but for 'philosophical anarchism' more generally. [ABSTRACT FROM AUTHOR]

Among the different polymorphs of LaLuO3 the hexagonal one is the least explored. Therefore, in this work, hexagonal LaLuO3 is grown and investigated in more detail. Two different growth templates are presented, offering the possibility to stabilize this hexagonal phase: Y2O3 on Si (111) and GaN on Al2O3 (0001). The LaLuO3 layers show smooth surfaces and high crystallinity for both types of templates. Spectroscopic characterization reveals a wide bandgap Eg of 5.6 eV and capacitance voltage measurements display a relative permittivity κ of 26, which makes hexagonal LaLuO3 a promising candidate as a future gate dielectric for devices based on hexagonal semiconductors such as GaN.

Our societies are marked not only by disagreements on the good life, but also by disagreements on justice. This motivates philosophers as divergent as John Gray and Chandran Kukathas to focus their normative political theories on peace instead of justice. In this article, I discuss how peace should be conceived if peace is to be a more realistic goal than justice, not presupposing a moral consensus. I distinguish two conceptions of peace to be found in the literature. One, ordinary peace, conceives of peace as non-violent coexistence based on modus vivendi arrangements. Modus vivendi arrangements, in turn, are explained as a special kind of compromise. Ordinary peace does not presuppose a moral consensus and is therefore realistic, but at the same time it is too minimalist and undemanding to be satisfying. The other conception of peace, ambitious peace, can be found in Kukathas’s work. It is a conception of peace ‘beyond compromise’, not minimalist and undemanding, but, I will argue, not realistic because presupposing at least a second-order moral consensus. In the end, I advocate a division of labour between both conceptions of peace under the umbrella of an overarching ideal of peace. [ABSTRACT FROM PUBLISHER]

The International Energy Agency Technology Collaboration Programme for Ocean Energy Systems (OES) initiated the OES Wave Energy Conversion Modelling Task, which focused on the verification and validation of numerical models for simulating wave energy converters (WECs). The long-term goal is to assess the accuracy of and establish confidence in the use of numerical models used in design as well as power performance assessment of WECs. To establish this confidence, the authors used different existing computational modelling tools to simulate given tasks to identify uncertainties related to simulation methodologies: (i) linear potential flow methods; (ii) weakly nonlinear Froude–Krylov methods; and (iii) fully nonlinear methods (fully nonlinear potential flow and Navier–Stokes models). This article summarizes the code-to-code task and code-to-experiment task that have been performed so far in this project, with a focus on investigating the impact of different levels of nonlinearities in the numerical models. Two different WECs were studied and simulated. The first was a heaving semi-submerged sphere, where free-decay tests and both regular and irregular wave cases were investigated in a code-to-code comparison. The second case was a heaving float corresponding to a physical model tested in a wave tank. We considered radiation, diffraction, and regular wave cases and compared quantities, such as the WEC motion, power output and hydrodynamic loading. [ABSTRACT FROM AUTHOR]

The cellular surfaceome and its residing extracellularly exposed proteins are involved in a multitude of molecular signaling processes across the viral infection cycle. Successful viral propagation, including viral entry, immune evasion, virion release and viral spread rely on dynamic molecular interactions with the surfaceome. Decoding of these viral-host surfaceome interactions using advanced technologies enabled the discovery of fundamental new functional insights into cellular and viral biology. In this review, we highlight recently developed experimental strategies, with a focus on spatial proteotyping technologies, aiding in the rational design of theranostic strategies to combat viral infections., Competing Interests: Conflict of interest statement The authors declare no conflicts of interest, competing interests or financial interests., (Copyright © 2021 Elsevier Inc.
