Wiecie, czego naprawdę nie znoszę w długie weekendy?
Nawet nie zmian rozkładu, ale tego, że dla mniejszych przewoźników, po prostu nie idzie znaleźć informacji, czy w piątek autobusy kursują według rozkładu dla dni roboczych czy weekendowego. I oczywiście jeden z drugim z reguły różnią się tak bardzo, że nawet nie można wybrać jednego kursu, który na pewno pojedzie.
Tak, pomyślałem, żeby jutro rano pojechać do Kórnika. Pewnie nikt tu przypadkiem nie orientuje się, jak jutro jeżdż…

AMLgentex: Mobilizing Data-Driven Research to Combat Money Laundering
Money laundering enables organized crime by allowing illicit funds to enter the legitimate economy. Although trillions of dollars are laundered each year, only a small fraction is ever uncovered. This stems from a range of factors, including deliberate evasion by launderers, the rarity of confirmed cases, and the limited visibility each financial institution has into the global transaction network. While several synthetic datasets are available, they fail to model the structural and behavioral …

High yield, low disorder Si/SiGe heterostructures for spin qubit devices manufactured in a BiCMOS pilot line
The prospect of achieving fault-tolerant quantum computing with semiconductor spin qubits in Si/SiGe heterostructures relies on the integration of a large number of identical devices, a feat achievable through a scalable (Bi)CMOS manufacturing approach. To this end, both the gate stack and the Si/SiGe heterostructure must be of high quality, exhibiting uniformity across the wafer and consistent performance across multiple fabrication runs. Here, we report a comprehensive investigation of Si/SiG…

The quantum Ramsey number $QR(2,2)$
Operator systems of matrices can be viewed as quantum analogues of finite graphs. This analogy suggests many natural combinatorial questions in linear algebra. We determine the quantum Ramsey numbers $QR(2,k)$ and the lower quantum Turán numbers $T^\downarrow(n, m)$ with $n > 3m$. In particular, we conclude that $QR(2,2) = 4$ and confirm Weaver's conjecture that $T^\downarrow(4, 1) = 4$. We also obtain a new result for the existence of anticliques in quantum graphs of low dimension.

QCD-inspired description of multiplicity distributions in jets
We suggest a universal QCD-motivated expression for the Polyakov-KNO multiplicity distributions of hadrons in jets and compare it with data from $e^+e^-$ annihilation experiments. The moments and overall shape of the distributions in full events and quark and gluon jets, over a range of energies, are described with reasonable quantitative precision. In particular, the scaling violation predicted by QCD is seen clearly in the moments and high-multiplicity fluctuations.

Temperature Dependence of Heavy Quark Diffusion from (2+1)-flavor Lattice QCD
We present a lattice determination of the heavy-quark diffusion coefficient in (2+1)-flavor QCD with almost physical quark masses. The momentum and spatial diffusion coefficients are extracted for a wide temperature range, from $T=163$ MeV to $10$ GeV. The results are in agreement with previous works from the HotQCD collaboration, and show fast thermalization of the heavy quark inside the QGP. Near the chiral crossover temperature $T_c\simeq150$ MeV, our results are close to the AdS/CFT estimat…

300 mm Wafer-Scale SiN Platform for Broadband Soliton Microcombs Compatible with Alkali Atomic References
Chip-integrated optical frequency combs (OFCs) based on Kerr nonlinear resonators are of great significance given their scalability and wide range of applications. Broadband on-chip OFCs reaching visible wavelengths are especially valuable as they address atomic clock transitions that play an important role in position, navigation, and timing infrastructure. Silicon nitride (SiN) deposited via low pressure chemical vapor deposition (LPCVD) is the usual platform for the fabrication of chip-integ…

A new Limit for Axion Dark Matter with SPACE
The axion, which has yet to be discovered, is a promising candidate for dark matter that emerges from Peccei-Quinn theory. This article presents the search for axion dark matter with the "Student Project for an Axion Cavity Experiment" (SPACE), which is also the first one in Germany. The hypothetical particle was looked for in the mass range from $16.626~\mathrm{μeV}$ to $16.653~\mathrm{μeV}$, corresponding to a frequency range of 4.020 GHz to 4.027 GHz, using a resonant cavity in a peak magn…
