We study the K-stability of blow-ups of the weighted projective plane ${\mathbb P}(1,1,n)$, where n is a positive integer.

Often, accounts of epistemic injustice either conflate epistemic harming with epistemic wronging or assume epistemic injustice is grounded in instances of epistemic harm. Recently, Dunne and Kotsonis (2024) have argued that neither conflation nor grounding make sense; the two are separate phenomena and have attempted to show how the two relate to one another. I argue this approach is mistaken: rather than just distinguish epistemic harming and wronging, instead we should question the very existence of epistemic harm. First, I discuss the relationship between epistemic harm and epistemic wrong and briefly summarize the ways in which they come apart. While I argue that Dunne and Kotsonis’ arguments are unsuccessful, I offer a new argument to the same effect, showing that current accounts of epistemic harm are underinclusive with respect to epistemic wronging. Second, I show that, generally, wronging does not require harming. Finally, I give us reason to believe that indeed, epistemic harm doesn’t exist: I argue that the notion of intrinsically epistemic harm is suspect, and does not fit within extant theorization on harm more generally and that we, therefore, ought to abandon it entirely: like the general case, epistemic wrong can exist without epistemic harm. To modify a slogan proposed by Bradley, we should do away with epistemic harm.

We give combinatorially controlled series solutions to Dyson–Schwinger equations with multiple insertion places using tubings of rooted trees and investigate the algebraic relation between such solutions and the renormalization group equation.

As India and Pakistan emerged as two new nation-states after 1947, questions around nationality and citizenship animated official and public discourses. While there were constitutional and legal pronouncements to clarify these matters, this article suggests that particular documents governing mobility became central to how such issues were framed and understood. In particular, this article focuses on the Indian passport and similar documents of mobility control, such as the domicile certificate, permits, and so on, to examine how they worked singly and in conjunction to frame the documentary life of belonging. The article also focuses on particular mobile groups, Muslim minorities and women married to non-Indians, to understand how these documents became central to their claims of citizenship and belonging.

Human interactions in the online world comprise a combination of positive and negative exchanges. These diverse interactions can be captured using signed network representations, where edges take positive or negative weights to indicate the sentiment of the interaction between individuals. Signed networks offer valuable insights into online political polarization by capturing antagonistic interactions and ideological divides on social media platforms. This study analyzes polarization on Menéame, a Spanish social media platform that facilitates engagement with news stories through comments and voting. Using a dual-method approach—Signed Hamiltonian Eigenvector Embedding for Proximity for signed networks and Correspondence Analysis for unsigned networks—we investigate how including negative ties enhances the understanding of structural polarization levels across different conversation topics on the platform. While the unsigned Menéame network effectively delineates ideological communities, only by incorporating negative ties can we identify ideologically extreme users who engage in antagonistic behaviors: without them, the most extreme users remain indistinguishable from their less confrontational ideological peers.

Understanding how law is articulated by computer means becomes crucial amid the widespread use of algorithmic decision-making systems (ADMs) in public policies. Based on a case study of the profiling algorithm deployed in labour market policies in Poland, this article contributes to the debate on computer representation of law. Using unique data concerning ADMs and their development, we address the following questions: How is the law articulated through algorithms? Who produces, and how, what kinds of discrepancies between the law and ADMs? Our analysis revealed discrepancies that were indicative of political decision-making that go far beyond adaptations of law to the requirements of ADMs. Furthermore, contrary to what the literature suggests, these discrepancies were a product of backstage decision-making by traditional policy-makers – executive and public administration – rather than system-level bureaucrats. Thus, we argue for the need to incorporate the political dimension more systematically into the analysis of computer articulation of law.

This article analyzes the evolution of banking supervision in Spain under Franco’s regime (1939–1975), highlighting how political and economic factors shaped oversight in an authoritarian setting. Two phases emerge. In the 1940s–50s, supervision—lodged in the Ministry of Finance—was weak, poorly staffed, and focused on enforcing banks’ oligopolistic interest rate agreements, reflecting regulatory capture. Following the 1959 Stabilization Plan, rising external pressure, domestic concerns about oligopolistic practices, and the 1962 Banking Law prompted reform. Supervision shifted to the Bank of Spain with the establishment of the Private Banking Inspection Service, resulting in more frequent inspections and gradual formalization of supervision. Archival records indicate that by the 1970s, inspections had become more frequent and rigorous, signaling a cautious shift toward risk-based oversight. However, the reforms remained incomplete. Persistent systemic vulnerabilities culminated in the severe banking crisis of 1977–1982, underlining the limitations of supervisory transformation under authoritarian rule.

Interactions between hyperelastic bio-membranes and fluid play a crucial role in the flight (or swimming) motion of many creatures, such as bats, flying squirrels and lemurs. Bio-membranes are characterised by high stretchability and micro-bending stiffness, leading to unique fluid–solid coupling properties (Mathai et al., 2023, Phys. Rev. Lett., vol. 131, 114003). This study presents a high-fidelity numerical exploration of the hyperelastic characteristics of a pitching foil inspired by bio-membranes in fluid within a low Reynolds number regime. The focus is on the effect of foil compliance on its self-propulsion performance, mimicking natural propulsion mechanisms, with the foil free to move in the horizontal direction. We find that with certain compliance, the foil may experience a velocity crisis, meaning that its propulsive capability is completely lost. This phenomenon is caused by the loss of beat speed when the foil’s passive deformation is out of phase with the pitching motion. By contrast, the two motions can be in phase at proper compliance, leading to an increased beat speed. This will significantly enhance propulsive velocity up to $33\,\%$ compared with the rigid case. The results demonstrate the feasibility of compliance tuning to circumvent the velocity crisis and improve the propulsive speed, which are helpful in the design of micro aerial robots using biomimetic membranes.
