An important part of Iran’s censorship apparatus is its analysis of unencrypted protocols such as HTTP and DNS. During routine evaluations of Iran’s HTTP and DNS censorship, we noticed several properties we believe to be unknown today. For instance, we found injections of correct static IPs for some domains such as google.com on the DNS level, unclear HTTP version parsing, and correlations between DNS and HTTP censorship. In this paper, we present our findings to the community and discuss possible takeaways for affected people and the censorship circumvention community. As some of our findings left us bewildered, we hope to ignite a discussion about Iran’s censorship behavior.

By encrypting the SNI extension, the Encrypted ClientHello (ECH) prevents censors from blocking TLS traffic to certain domains. Despite this promising outlook, ECH’s current capability to contest TLS censorship is unclear; for instance, Russia has started censoring ECH connections successfully. This paper clarifies ECH’s current role for TLS censorship. To this end, we evaluate servers’ support for ECH and its analysis and subsequent blocking by censors. We determine Cloudflare as the only major provider supporting ECH. Additionally, we affirm previously known ECH censorship in Russia and uncover indirect censorship of ECH through encrypted DNS censorship in China and Iran. Our findings suggest that ECH’s contribution to censorship circumvention is currently limited: we consider ECH’s dependence on encrypted DNS especially challenging for ECH’s capability to circumvent censorship. We stress the importance of censorship-resistant ECH to solve the long-known problem of SNI-based TLS censorship.","lang":"eng"}]},{"citation":{"bibtex":"@article{Pöllmann_2025, title={Dimensiones transnacionales y multilingües de la educación intercultural: Resultados de una encuesta a futuros docentes en Badajoz (España) y Posadas (Argentina)}, volume={13}, number={25}, journal={Revista La Rivada}, publisher={Universidad Nacional de Misiones}, author={Pöllmann, Andreas}, year={2025}, pages={22–41} }","ama":"Pöllmann A.

Country-level analyses reveal a staggered effect on market activity, with predominantly international issuers adjusting their bond listings between the initially scheduled Brexit date and the final withdrawal date. At the issuer level, our findings indicate that the relative attractiveness of the EEA30 market has increased post-Brexit.

Current-voltage (I-U) characteristics, recorded at variable temperatures from LiNbO3 (LNO) DWs, are clearly able to differentiate between these two contributions. Practically, they allow us to directly quantify the physical parameters relevant to the two mechanisms (a) and (b) mentioned above. These are, for example, the resistance of the DW, the saturation current, the ideality factor, and the Schottky barrier height of the electrode-DW junction. Furthermore, the activation energies needed to initiate the thermally activated electronic transport along the DWs can be extracted. In addition, we show that electronic transport along LNO DWs can be elegantly viewed and interpreted in an adapted semiconductor picture based on a double-diode, double-resistor equivalent-circuit model, the R2D2 model. Finally, our R2D2 model was checked for its universality by successfully fitting the I-U curves of not only z-cut LNO bulk DWs, but equally of z-cut thin-film LNO DWs, and of x-cut thin-film DWs as reported in literature."}],"date_created":"2024-02-06T08:02:15Z","department":[{"_id":"15"},{"_id":"169"},{"_id":"623"},{"_id":"288"}],"keyword":["General Physics and Astronomy"],"type":"journal_article","publication_identifier":{"issn":["2331-7019"]},"author":[{"first_name":"Manuel","last_name":"Zahn","full_name":"Zahn, Manuel"},{"full_name":"Beyreuther, Elke","last_name":"Beyreuther","first_name":"Elke"},{"first_name":"Iuliia","last_name":"Kiseleva","full_name":"Kiseleva, Iuliia"},{"first_name":"Ahmed Samir","last_name":"Lotfy","full_name":"Lotfy, Ahmed Samir"},{"full_name":"McCluskey, Conor J.","last_name":"McCluskey","first_name":"Conor J."},{"full_name":"Maguire, Jesi R.","last_name":"Maguire","first_name":"Jesi R."},{"full_name":"Suna, Ahmet","last_name":"Suna","first_name":"Ahmet"},{"id":"22501","full_name":"Rüsing, Michael","last_name":"Rüsing","orcid":"0000-0003-4682-4577","first_name":"Michael"},{"full_name":"Gregg, J.

To this end, we define a novel inertial gradient-like dynamical system in the multiobjective setting, which trajectories converge weakly to Pareto optimal solutions. Discretization of this system yields an inertial multiobjective algorithm which generates sequences that converge weakly to Pareto optimal solutions. We employ Nesterov acceleration to define an algorithm with an improved convergence rate compared to the plain multiobjective steepest descent method (Algorithm 1). A further improvement in terms of efficiency is achieved by avoiding the solution of a quadratic subproblem to compute a common step direction for all objective functions, which is usually required in first-order methods. Using a different discretization of our inertial gradient-like dynamical system, we obtain an accelerated multiobjective gradient method that does not require the solution of a subproblem in each step (Algorithm 2). While this algorithm does not converge in general, it yields good results on test problems while being faster than standard steepest descent.","lang":"eng"}]},{"publication":"arXiv:2402.06376","citation":{"mla":"Sonntag, Konstantin, et al. “A Descent Method for Nonsmooth Multiobjective Optimization in Hilbert Spaces.” <i>ArXiv:2402.06376</i>, 2024.","bibtex":"@article{Sonntag_Gebken_Müller_Peitz_Volkwein_2024, title={A Descent Method for Nonsmooth Multiobjective Optimization in Hilbert Spaces}, journal={arXiv:2402.06376}, author={Sonntag, Konstantin and Gebken, Bennet and Müller, Georg and Peitz, Sebastian and Volkwein, Stefan}, year={2024} }","ama":"Sonntag K, Gebken B, Müller G, Peitz S, Volkwein S.

Exploiting translational equivariances, the high-dimensional distributed control problem can be transformed into a multi-agent control problem with many identical, uncoupled agents. Furthermore, using the fact that information is transported with finite velocity in many cases, the dimension of the agents’ environment can be drastically reduced using a convolution operation over the state space of the PDE, by which we effectively tackle the curse of dimensionality otherwise present in deep reinforcement learning. In this setting, the complexity can be flexibly adjusted via the kernel width or by using a stride greater than one (meaning that we do not place an actuator at each sensor location). Moreover, scaling from smaller to larger domains – or the transfer between different domains – becomes a straightforward task requiring little effort. We demonstrate the performance of the proposed framework using several PDE examples with increasing complexity, where stabilization is achieved by training a low-dimensional deep deterministic policy gradient agent using minimal computing resources.","lang":"eng"}],"publication":"Physica D: Nonlinear Phenomena","doi":"10.1016/j.physd.2024.134096","language":[{"iso":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1016/j.physd.2024.134096"}],"intvolume":"       461","article_type":"original","date_updated":"2024-02-23T10:53:42Z","author":[{"full_name":"Peitz, Sebastian","first_name":"Sebastian","last_name":"Peitz","orcid":"0000-0002-3389-793X","id":"47427"},{"first_name":"Jan","last_name":"Stenner","full_name":"Stenner, Jan","id":"65520"},{"full_name":"Chidananda, Vikas","last_name":"Chidananda","first_name":"Vikas"},{"last_name":"Wallscheid","orcid":"https://orcid.org/0000-0001-9362-8777","first_name":"Oliver","full_name":"Wallscheid, Oliver","id":"11291"},{"full_name":"Brunton, Steven L.","first_name":"Steven L.","last_name":"Brunton"},{"full_name":"Taira, Kunihiko","first_name":"Kunihiko","last_name":"Taira"}],"year":"2024","title":"Distributed Control of Partial Differential Equations Using  Convolutional Reinforcement Learning"}]
