Dynamic $(1+ε)$-Approximate Matching Size in Truly Sublinear Update Time
We show a fully dynamic algorithm for maintaining $(1+ε)$-approximate \emph{size} of maximum matching of the graph with $n$ vertices and $m$ edges using $m^{0.5-Ω_ε(1)}$ update time. This is the first polynomial improvement over the long-standing $O(n)$ update time, which can be trivially obtained by periodic recomputation. Thus, we resolve the value version of a major open question of the dynamic graph algorithms literature (see, e.g., [Gupta and Peng FOCS'13], [Bernstein and Stein SODA'16]…

Mass action systems: two criteria for Hopf bifurcation without Hurwitz
We state two sufficient criteria for periodic oscillations in mass action systems. Neither criterion requires a computation of the Hurwitz determinants. The first criterion also applies to general kinetics and it concerns fully-open systems: in essence, it guarantees periodic oscillations whenever the system admits a steady state with a simple pair of complex conjugate eigenvalues with positive real part. The second criterion states an algebraic condition based on the steady-state Jacobian matr…

Race Against the Machine: a Fully-annotated, Open-design Dataset of Autonomous and Piloted High-speed Flight
Unmanned aerial vehicles, and multi-rotors in particular, can now perform dexterous tasks in impervious environments, from infrastructure monitoring to emergency deliveries. Autonomous drone racing has emerged as an ideal benchmark to develop and evaluate these capabilities. Its challenges include accurate and robust visual-inertial odometry during aggressive maneuvers, complex aerodynamics, and constrained computational resources. As researchers increasingly channel their efforts into it, they…

My current take on the #xz situation, not having read the actual source backdoor commits yet (thanks a lot #Github for hiding the evidence at this point...) besides reading what others have written about it (cf. #rustlang for such central library dependencies would maybe (really big maybe) have made it a bit harder to push a backdoor like this because - if and only if the safety features are used idiomatically in an open source project - reasonably looking code is (a bit?) more limited in the sneaky behavior it could include. We should still very much use those languages over C/C for infrastructure code because the much larger class of unintentional bugs is significantly mitigated, but I believe (without data to back it up) that even such "bugdoor" type changes will be harder to execute. However, given the sophistication in this case, it may not have helped at all. The attacker(s) have shown to be clever enough.
6. Sandboxing library code may have helped - as the attacker(s) explicitly disabled e.g. landlock, that might already have had some impact. We should create better tooling to make it much easier to link to infrastructure libraries in a sandboxed way (although that will have performance implications in many cases).
7. Automatic reproducible builds verification would have mitigated this particular vector of backdoor distribution, and the Debian team seems to be using the reproducibility advances of the last decade to verify/rebuild the build servers. We should build library and infrastructure code in a fully reproducible manner *and* automatically verify it, e.g. with added transparency logs for both source and binary artefacts. In general, it does however not prevent this kind of supply chain attack that directly targets source code at the "leaf" projects in Git commits.
8. Verifying the real-life identity of contributors to open source projects is hard and a difficult trade-off. Something similar to the #Debian #OpenPGP #web-of-trust would potentially have mitigated this style of attack somewhat, but with a different trade-off. We might have to think much harder about trust in individual accounts, and for some projects requiring a link to a real-world country-issued ID document may be the right balance (for others it wouldn't work). That is neither an easy nor a quick path, though. Also note that sophisticated nation state attackers will probably not have a problem procuring "good" fake IDs. It might still raise the bar, though.
9. What happened here seems clearly criminal - at least under my IANAL naive understanding of EU criminal law. There was clear intent to cause harm, and that makes the specific method less important. The legal system should also be able to help in mitigating supply chain attacks; not in preventing them, but in making them more costly if attackers can be tracked down (this is difficult in itself, see point 8) and face risk of punishment after the fact.

Optimal control in large open quantum systems: the case of transmon readout and reset
We present a framework that combines the adjoint state method together with reverse-time back-propagation to solve prohibitively large open-system quantum control problems.

It is scalable, computationally efficient, and has a low memory footprint. We apply this framework to optimize two inherently dissipative operations in s…

Determination of output composition in reaction-advection-diffusion systems on network reactors
We consider reaction-transport processes in open reactors in which systems of first order reactions involving a number of gas species and solid catalysts can occur at localized active regions. Reaction products flow out of the reactor into vacuum conditions and are collected at an exit boundary. The output composition problem (OCP) is to determine the composition (molar fractions) of the collected gas after the reactor is fully emptied. We provide a solution to this problem in the form of a bou…

The reciprocity approach is a powerful method to determine the expected signal power of axion haloscopes in a model-independent way. Especially for open and broadband setups like the MADMAX dielectric haloscope the sensitivity to the axion field is difficult to calibrate since they do not allow discrete eigenmode analysis and are optically too large to fully simulate. The central idea of the reciprocity approach is to measure a reflection-induced test field in the setup instead of trying to sim…

Maximum Entropy Principle as Postulate of Quantum Mechanics
Even a century after the formulation of Quantum Mechanics (QM), the wave function collapse (WFC) remains a contentious aspect of the theory. Environment-induced decoherence has offered a partial resolution by illustrating how unitary evolution in an open quantum system can lead to effective WFC within its components. However, this approach by itself does not lead to a fully self-consistent reformulation of QM. We introduce a modified set of QM postulates, which exclude both WFC and Born's proba…

A Quantitative Autonomy Quantification Framework for Fully Autonomous Robotic Systems
Although autonomous functioning facilitates deployment of robotic systems in domains that admit limited human oversight on our planet and beyond, finding correspondence between task requirements and autonomous capability is still an open challenge. Consequently, a number of methods for quantifying autonomy have been proposed over the last three decades, but to our knowledge all these have no discernment of sub-mode features of variation of autonomy and some are based on metrics that violet the …

Lyapunov-Based Deep Residual Neural Network (ResNet) Adaptive Control
Deep Neural Network (DNN)-based controllers have emerged as a tool to compensate for unstructured uncertainties in nonlinear dynamical systems. A recent breakthrough in the adaptive control literature provides a Lyapunov-based approach to derive weight adaptation laws for each layer of a fully-connected feedforward DNN-based adaptive controller. However, deriving weight adaptation laws from a Lyapunov-based analysis remains an open problem for deep residual neural networks (ResNets). This paper…

SWIFT: A modern highly-parallel gravity and smoothed particle hydrodynamics solver for astrophysical and cosmological applications
Numerical simulations have become one of the key tools used by theorists in all the fields of astrophysics and cosmology. The development of modern tools that target the largest existing computing systems and exploit state-of-the-art numerical methods and algorithms is thus crucial. In this paper, we introduce the fully open-source highly-parallel, versatile, and modular coupled hydrodynamics, gravity, cosmology, and galaxy-formation code SWIFT. The software package exploits hybrid shared- and …

An Open, Programmable, Multi-vendor 5G O-RAN Testbed with NVIDIA ARC and OpenAirInterface
The transition of fifth generation (5G) cellular systems to softwarized, programmable, and intelligent networks depends on successfully enabling public and private 5G deployments that are (i) fully software-driven and (ii) with a performance at par with that of traditional monolithic systems. This requires hardware acceleration to scale the Physical (PHY) layer performance, end-to-end integration and testing, and careful planning of the Radio Frequency (RF) environment. In this paper, we descri…

A faster FPRAS for #NFA
Given a non-deterministic finite automaton (NFA) A with m states, and a natural number n (presented in unary), the #NFA problem asks to determine the size of the set L(A_n) of words of length n accepted by A. While the corresponding decision problem of checking the emptiness of L(A_n) is solvable in polynomial time, the #NFA problem is known to be #P-hard. Recently, the long-standing open question -- whether there is an FPRAS (fully polynomial time randomized approximation scheme) for #NFA -- w…

Potentialisations of a class of fully-nonlinear symmetry-integrable evolution equations
We consider here the class of fully-nonlinear symmetry-integrable third-order evolution equations in 1+1 dimensions that were proposed recently in {\it Open Communications in Nonlinear Mathematical Physics}, vol. 2, 216--228 (2022). In particular, we report all zero-order and higher-order potentialisations for this class of equations using their integrating factors (or multipliers) up to order four. Chains of connecting evolution equations are also obtained by multi-potentialisations.

Page-curve-like entanglement dynamics in open quantum systems
The entanglement entropy of a black hole, and that of its Hawking radiation, are expected to follow the so-called Page curve: After an increase in line with Hawking's calculation, it is expected to decrease back to zero once the black hole has fully evaporated, as demanded by unitarity. Recently, a simple system-plus-bath model has been proposed which shows a similar behaviour. Here, we make a general argument as to why such a Page-curve-like entanglement dynamics should be expected to hold gen…

Rethinking Cross-Domain Sequential Recommendation under Open-World Assumptions
Cross-Domain Sequential Recommendation (CDSR) methods aim to tackle the data sparsity and cold-start problems present in Single-Domain Sequential Recommendation (SDSR). Existing CDSR works design their elaborate structures relying on overlapping users to propagate the cross-domain information. However, current CDSR methods make closed-world assumptions, assuming fully overlapping users across multiple domains and that the data distribution remains unchanged from the training environment to the …
