Conceptual Mapping of Controversies
With our work, we contribute towards a qualitative analysis of the discourse on controversies in online news media. For this, we employ Formal Concept Analysis and the economics of conventions to derive conceptual controversy maps. In our experiments, we analyze two maps from different news journals with methods from ordinal data science. We show how these methods can be used to assess the diversity, complexity and potential bias of controversies. In addition to that, we discuss how the diagram…

Tunneling time, the barrier time-delay and weak measurement What was or can actually be measured with the Attoclock?
The measurement of the tunneling time-delay in attosecond experiments, termed attoclock, despite its controversies, offers a fruitful opportunity to understand the tunneling time and the tunnel-ionization process. In previous work, we showed a model that well describes the time-delay measured by the attoclock experiment in the adiabatic and nonadiabatic field calibrations. In the present work we show that the tunneling time reveals a universal behavior, with disentangled contribution, where the…

Abstract: This paper comprehensively analyzes the Pegasus spyware and its implications for digital privacy and security. The Israeli cyber intelligence company NSO Group's Pegasus has gained recognition as a potent surveillance tool capable of hacking into smartphones and extracting data without the user's knowledge [49], [50]. The research emphasizes the technical aspects of this spyware, its deployment methods, and the controversies surrounding its use. The research also emphasizes the growing worries surrounding digital privacy and security as a result of the prevalent use of advanced spyware. By delving into legal, ethical, and policy issues, the objective of this study is to deliver a holistic understanding of the challenges posed by Pegasus and similar spyware tools. Through a comprehensive examination of the subject, the paper presents potential solutions to mitigate the threats and protect users from invasive surveillance techniques.

Superconductivity and metallic behavior in heavily doped bulk single crystal diamond and graphene/diamond heterostructure
Owing to extremely large band gap of 5.5 eV and high thermal conductivity, diamond is recognized as the most important semiconductor. The superconductivity of polycrystalline diamond has always been reported, but there are also many controversies over the existence of superconductivity in bulk single crystal diamond and it remains a question whether a metallic state exists for such a large band gap semiconductor. Herein, we realize a single crystal superconducting diamond with a Hall carrier co…

Fabrication-induced even-odd discrepancy of magnetotransport in few-layer MnBi$_2$Te$_4$
The van der Waals antiferromagnetic topological insulator MnBi2Te4 represents a promising platform for exploring the layer-dependent magnetism and topological states of matter. Recently observed discrepancies between magnetic and transport properties have aroused controversies concerning the topological nature of MnBi2Te4 in the ground state. In this article, we demonstrate that fabrication can induce mismatched even-odd layer dependent magnetotransport in few-layer MnBi2Te4. We perform a compr…

Relaxation of weakly collisional plasma: continuous spectra, Landau eigenmodes, and transition from the collisionless to the fluid limit
The relaxation of a weakly collisional plasma is described by the Boltzmann-Poisson equations with the Lenard-Bernstein collision operator. We perform a perturbative analysis of these equations, and obtain, for the first time, exact analytic solutions, enabling definitive resolutions to long-standing controversies regarding the impact of weak collisions on continuous spectra and Landau eigenmodes. Unlike some previous studies, we retain both damping and diffusion terms in the collision operator…

Generative Adversarial Collaborations: A practical guide for conference organizers and participating scientists
Generative adversarial collaborations (GACs) are a form of formal teamwork between groups of scientists with diverging views. The goal of GACs is to identify and ultimately resolve the most important challenges, controversies, and exciting theoretical and empirical debates in a given research field. A GAC team would develop specific, agreed-upon avenues to resolve debates in order to move a field of research forward in a collaborative way. Such adversarial collaborations have many benefits and …
