Description of CRESST-III lithium aluminate data
Two detector modules with lithium aluminate targets were operated in the CRESST underground setup between February and June 2021. The data collected in this period was used to set the currently strongest cross-section upper limits on the spin-dependent interaction of dark matter (DM) with protons and neutrons for the mass region between 0.25 and 1.5 GeV/c$^2$. The data are available online. In this document, we describe how the data set should be used to reproduce our dark matter results.

Gas price shocks, uncertainty and price setting: evidences from Italian firms
This paper examines how natural gas price shocks affect Italian firms' pricing decisions and inflation expectations using quarterly survey data from the Bank of Italy's Survey on Inflation and Growth Expectations (SIGE) spanning 1999Q4-2025Q2. We identify natural gas price shocks through a Bayesian VAR with sign and zero restrictions. Our findings reveal that these shocks are a primary driver of firms' inflation expectations, particularly during the post-COVID period (2021-2023) when supply dis…

👋 Hello! I’m Łukasz. Thirty-something, living in Warsaw, Poland. On fedi since 2021 or so. Right now, I'm merging my two accounts into one and giving this profile a fresh new start.
I live a few parallel lives.
Most of the time I’m a web developer. I work with TypeScript, React and all that jazz. But I still enjoy static site generators and good ol’ HTML/CSS.
In another life, I’m a documentary photographer and photojournalist. I’m interested in activism, art and culture, politics, and pretty much anything interesting happening on city streets. A big part of my photography journey involves documenting protests and demonstrations in Poland, especially those related to human rights and social issues. I’m also drawn to street art, particularly when it carries strong messages.
I occasionally blog and translate. Many years ago I wrote two books about WordPress. However, these days I’m more likely to go outside and touch grass than spend even more time in front of a screen.
Outside of that, expect me to post about mental health and politics. I promise to use CWs when appropriate.
I post in both English and Polish, depending on the topic.
Aaaand that’s it. Nice to meet you! ☺️

Moment-SOS hierarchies for arrow-type polynomial matrix inequalities with applications to structural optimization
The Arrow Decomposition (AD) technique, initially introduced in [Mathematical Programming 190(1-2) (2021), pp 105-134], demonstrated superior scalability over the classical chordal decomposition in the context of Linear Matrix Inequalities (LMIs) if the matrix in question satisfied suitable assumptions. The primary objective of this paper is to extend the AD method to address Polynomial Optimization Problems (POPs) involving large-scale Polynomial Matrix Inequalities (PMIs), with the solution f…

Good Morning #Canada
There is a little known reporting tool on the ##StatsCan website called Canada’s Quality of Life Hub. First proposed in 2021, and launched in 2023, it is a framework that gathers data and evidence to inform priority setting and guide decision-making in various policy areas, including the budgetary process. The Framework comprises five domains –prosperity, health, environment, society, and good governance – and two cross-cutting lenses: fairness and inclusion, and sustainability and resilience. Not enough Canadians have heard of it, and I suspect very few government policies are implemented before analyzing the impact on quality of life measurement by this tool. On a positive note, #StatsCan is looking for feedback on how to improve the hub.

Our proof is based on a general principle of applying the P-function method to such uniqueness results. As a further app…

First observation of the Josephson-Anderson relation in experiments on hydrodynamic drag
We verify a recent prediction (Eq. 3.50 in G. L. Eyink, Phys. Rev. X 11, 031054 (2021)) for the drag on an object moving through a fluid. In this prediction the velocity field is decomposed into a nonvortical (potential) and vortical contribution, and so is the associated drag force. In the Josephson-Anderson relation the vortical contribution of the drag force follows from the flux of vorticity traversing the streamlines of the corresponding potential flow. The potential component is directly …

Stoquasticity is not enough: towards a sharper diagnostic for Quantum Monte Carlo simulability
Quantum Monte Carlo (QMC) methods are powerful tools for simulating quantum many-body systems, yet their applicability is limited by the infamous sign problem. We approach this challenge through the lens of Vanishing Geometric Phases (VGP) \cite{Hen_2021}, introducing it as a `geometric' criterion for diagnosing QMC simulability. We characterize the class of VGP Hamiltonians, and analyze the complexity of recognizing this class, identifying both hard and efficiently identifiable cases. We furth…

A direct approach to tree-guided feature aggregation for high-dimensional regression
In high-dimensional linear models, sparsity is often exploited to reduce variability and achieve parsimony. Equi-sparsity, where one assumes that predictors can be aggregated into groups sharing the same effects, is an alternative parsimonious structure that can be more suitable in certain applications. Previous work has clearly demonstrated the benefits of exploiting equi-sparsity in the presence of ``rare features'' (Yan and Bien 2021). In this work, we propose a new tree-guided regularizatio…

In the complex representation of the 3-dimensional Heisenberg algebra, proposed by Turbiner-Vasilevski (2021) in Ref.7, this construction is reduced to the linear differential operators in $(\frac{\partial}{\partial \overline{z}}\,,\,\frac{\partial}{\partial z})$ acting on …

Mexico 2021: Psychological Intimate Partner Violence Against Women and the Role of Childhood Violence Exposure -- A Machine Learning Approach
In 2021, psychological violence was the most prevalent form of intimate partner violence (IPV) suffered by women in Mexico. The consequences of psychological IPV can include low self-esteem, depression, and even potential suicide. It is, therefore, crucial to identify the most relevant risk and protective factors of psychological IPV against women in Mexico. To this end, we adopt an ecological approach and analyze the role of a wide range of factors across four interrelated levels: Individual, …

Multiwavelength study of Galactic PeVatron LHAASO J0341+5258
Galactic PeVatrons are astrophysical sources accelerating particles up to a few PeV (~10$^{15}$ eV). The primary method to identify both electron and proton PeVatrons is the observation of $γ$-ray radiation at ultra-high energies (UHE; E$>$100 TeV). In 2021, LHAASO detected 14 steady $γ$-ray sources with photon energies above 100 TeV and up to 1.4 PeV. Most of these sources can be plausibly associated with objects such as supernova remnants, pulsar wind nebulae, and stellar clusters. However,…

The $3$-sparsity of $X^n-1$ over finite fields, II
Let $q$ be a prime power and $\mathbb{F}_q$ the finite field with $q$ elements. For a positive integer $n$, the polynomial $X^n - 1 \in \mathbb{F}_q[X]$ is termed $3$-sparse over $\mathbb{F}_q$ if all its irreducible factors in $\mathbb{F}_q[X]$ are either binomials or trinomials. In 2021, Oliveira and Reis characterized all positive integers $n$ for which $X^n - 1$ is 3-sparse over $\mathbb{F}_q$ when $q = 2$ and $q = 4$. Recently, the author provided a complete characterization for odd $q$. T…

Who Gets Seen in the Age of AI? Adoption Patterns of Large Language Models in Scholarly Writing and Citation Outcomes
The rapid adoption of generative AI tools is reshaping how scholars produce and communicate knowledge, raising questions about who benefits and who is left behind. We analyze over 230,000 Scopus-indexed computer science articles between 2021 and 2025 to examine how AI-assisted writing alters scholarly visibility across regions. Using zero-shot detection of AI-likeness, we track stylistic changes in writing and link them to citation counts, journal placement, and global citation flows before and…

On the Smallest Size of Internal Collage Systems
A Straight-Line Program (SLP) for a stirng $T$ is a context-free grammar in Chomsky normal form that derives $T$ only, which can be seen as a compressed form of $T$. Kida et al.\ introduced collage systems [Theor. Comput. Sci., 2003] to generalize SLPs by adding repetition rules and truncation rules. The smallest size $c(T)$ of collage systems for $T$ has gained attention to see how these generalized rules improve the compression ability of SLPs. Navarro et al. [IEEE Trans. Inf. Theory, 2021] s…

Invariants of twisted current algebras and related Poisson-commutative subalgebras
Let q be a finite-dimensional Lie algebra and $θ$ an automorphism of q of order m. We extend $θ$ to an automorphism of the loop algebra of q and consider the fixed-point subalgebra $q[t,t^{-1}]^θ$. Using a splitting of $q[t,t^{-1}]^θ$, we construct $θ$-twisted Poisson-commutative versions of the Feigin--Frenkel centre and the universal Gaudin subalgebra introduced by Ilin and Rybnikov in 2021.

Enterprise Security Incident Analysis and Countermeasures Based on the T-Mobile Data Breach
This paper presents a comprehensive analysis of T-Mobile's critical data breaches in 2021 and 2023, alongside a full-spectrum security audit targeting its systems, infrastructure, and publicly exposed endpoints. By combining case-based vulnerability assessments with active ethical hacking techniques--including Shodan reconnaissance, API misuse simulations, VNC brute-forcing, firmware reverse engineering, and web application scans--we uncover structural weaknesses persisting beyond the initial b…

Asymptotic behavior of mass-critical Schrödinger equation in $ \mathbb{R}$
In this paper, we study the long-time behavior for the mass-critical nonlinear Schrödinger equation on the line \[ i\partial_t u + \partial_x^2 u = |u|^4 u, u(0, x) = u_0 \in L_x^2(\Bbb R). \] The global well-posedness and scattering for this equation was solved in Dodson [Amer. J. Math. (2016)]. Inspired by the pioneering work of Killip-Visan-Zhang [Amer. J. Math. (2021)], we show that solution can be approximated by a finite-dimensional Hamiltonian system. This system is th…

Mode stability for self-similar blowup of slightly supercritical NLS: II. high-energy spectrum
In continuation of the study of the companion work, we prove the high-energy mode stability for linearized operator around self-similar profiles in [Bahri-Martel-Raphaël, 2021] for slightly mass-supercritical NLS in $1 \le d \le 10$. This concludes the asymptotic stability of such self-similar blowup, and answers the question from [Bahri-Martel-Raphaël, 2021] and [Merle-Raphaël-Szeftel, 2010]. As a byproduct, we characterize the spectrum for linearized operator around mass-critical ground st…

Mode stability for self-similar blowup of slightly supercritical NLS: I. low-energy spectrum
We consider self-similar blowup for (NLS) $i\partial_t u + Δu + u|u|^{p-1} = 0$ in $d \ge 1$ and slightly mass-supercritical range $0 < s_c := \frac d2 - \frac{2}{p-1} \ll 1$. The existence and stability of such dynamics [Merle-Raphaël-Szeftel, 2010] and construction of suitable profiles [Bahri-Martel-Raphaël, 2021] lead to the question of asymptotic stability. Based on our previous work [Li, 2023], this nonlinear problem is reduced to linear mode stability of the matrix linearized…

Estimating Global HIV Prevalence in Key Populations: A Cross-Population Hierarchical Modeling Approach
Key populations at high risk of HIV infection are critical for understanding and monitoring HIV epidemics, but global estimation is hampered by sparse, uneven data. We analyze data from 199 countries for female sex workers (FSW), men who have sex with men (MSM), and people who inject drugs (PWID) over 2011-2021, and introduce a cross-population hierarchical model that borrows strength across countries, years, and populations. The model combines region- and population-specific means with country…
