Bousfield-Kan completion as a codensity $\infty$-monad
We develop a theory of codensity monads associated with full subcategories in the setting of $\infty$-categories. For an $\infty$-monad $\mathcal{M}$ on an $\infty$-category $\mathcal{C}$ that admits homotopy totalizations, we consider the $\mathcal{M}$-completion functor defined as the homotopy totalization of the canonical cosimplicial functor associated with $\mathcal{M}$. We prove that the $\mathcal{M}$-completion is the codensity $\infty$-monad of a full subcategory $\mathcal{A}(\mathcal{M…

Illumination number of 3-dimensional cap bodies
Despite recent progress on the Illumination conjecture, it remains open in general, as well as for specific classes of bodies. Bezdek, Ivanov, and Strachan showed that the conjecture holds for symmetric cap bodies in sufficiently high dimensions. Further, Ivanov and Strachan calculated the illumination number for the class of 3-dimensional centrally symmetric cap bodies to be 6. In this paper, we show that even the broader class of all 3-dimensional cap bodies has the same illumination number…

Computational algorithm for downward continuation of gravity anomalies
The downward continuation of potential fields from the Earth's surface into the subsurface is a critical task in gravity exploration, as it helps to identify the sources of gravity anomalies. This problem is often addressed by solving a first-kind integral equation using regularization techniques to stabilize an inherently unstable process. A similar approach is used in our work, where the continued field is represented as the potential of a simple layer or its vertical derivative. The constanc…

LITcoder: A General-Purpose Library for Building and Comparing Encoding Models
We introduce LITcoder, an open-source library for building and benchmarking neural encoding models. Designed as a flexible backend, LITcoder provides standardized tools for aligning continuous stimuli (e.g., text and speech) with brain data, transforming stimuli into representational features, mapping those features onto brain data, and evaluating the predictive performance of the resulting model on held-out data. The library implements a modular pipeline covering a wide array of methodological…

High-fidelity two-qubit gates with transmon qubits using bipolar flux pulses and tunable couplers
High-fidelity two-qubit gates are essential for scalable quantum computing. We present a scheme based on superconducting transmon qubits and a control pulse delivery protocol that enables arbitrary controlled-phase gates modulated solely by an independent arbitrary waveform generator pulse. We combined a tunable coupler design with bipolar flux-pulsing to demonstrate a high-fidelity gate with a performance of $99.5\%$. Our gates inherit the advantages of both approaches: minimal residual ZZ cou…

Investigation of tantalum films growth for coplanar resonators with internal quality factors above ten million
Alpha-tantalum on silicon is a promising platform for high-coherence superconducting quantum circuits. However, the growth mechanism of alpha-tantalum on silicon remains poorly understood. We present a comprehensive study on alpha-tantalum films growth on various substrate. The decisive role of a substrate material Debye temperature on phase selection mechanism in tantalum films growth is experimentally confirmed, contradicting the prior assumptions on substrate temperature influence. Crucially…

Three-loop singularity structure for a non-linear sigma model
The paper is devoted to the three-loop renormalization of the effective action for a two-dimensional non-linear sigma model using the background field method and a cutoff regularization in the coordinate representation. The coefficients of the renormalization constant and the necessary auxiliary vertices are found, as well as the asymptotic expansions of all three-loop diagrams, and their dependence on the type of regularizing function. A comparison is also made with the standard case of cutoff…
