Free Cosmic Density Bispectrum on Small Scales
We study the asymptotic behaviour of the free, cold-dark matter density fluctuation bispectrum in the limit of small scales. From an initially Gaussian random field, we draw phase-space positions of test particles which then propagate along Zel’dovich trajectories. A suitable expansion of...
Graph covers and semi-covers: Who is stronger?
The notion of graph cover, also known as locally bijective homomorphism, is a discretization of covering spaces known from general topology. It is a pair of incidence-preserving vertex- and edge-mappings between two graphs, the edge-component being bijective on the edge-neighborhoods of every...
Computing-heightened low-cost high-dimensional controlled-SUM gates
Qudit-based quantum gates offer several advantages over qubit-based counterparts, such as higher information density, the ability to address more complex problems, and richer quantum operations. In questo documento, we present three realistic protocols for implementing a 4$\times$4-dimensional (16D) two-qudit controlled-SUM (CSUM) gate,...
Mach-Zehnder atom interferometry with non-interacting trapped Bose Einstein condensates
The coherent manipulation of a quantum wave is at the core of quantum sensing. For instance, atom interferometers require linear splitting and recombination processes to map the accumulated phase shift into a measurable population signal. Although Bose Einstein condensates (BECs) are the...
SDVPT: Semantic-Driven Visual Prompt Tuning for Open-World Object Counting
Open-world object counting leverages the robust text-image alignment of pre-trained vision-language models (VLMs) to enable counting of arbitrary categories in images specified by textual queries. Tuttavia, widely adopted naive fine-tuning strategies concentrate exclusively on text-image consistency for categories contained in training, which...
Fine-tune Smarter, Not Harder: Parameter-Efficient Fine-Tuning for Geospatial Foundation Models
Earth observation (EO) is crucial for monitoring environmental changes, responding to disasters, and managing natural resources. In this context, foundation models facilitate remote sensing image analysis to retrieve relevant geoinformation accurately and efficiently. Tuttavia, as these models grow in size, fine-tuning becomes...
Selectivity filter conductance, rectification and fluctuations of subdomains – how can this all relate to the value of Hurst exponent in the dwell-times of ion channels states?
The Hurst effect in the signals describing ion channels’ activity has been known for many years. This effect is present in the experimental recordings of single-channel currents, but not only. The sequences of dwell times of functionally different channel states also exhibit...
StereoMamba: Real-time and Robust Intraoperative Stereo Disparity Estimation via Long-range Spatial Dependencies
Stereo disparity estimation is crucial for obtaining depth information in robot-assisted minimally invasive surgery (RAMIS). While current deep learning methods have made significant advancements, challenges remain in achieving an optimal balance between accuracy, robustezza, and inference speed. To address these challenges, Noi...
Classical Estimation of the Free Energy and Quantum Gibbs Sampling from the Markov Entropy Decomposition
We revisit the Markov Entropy Decomposition, a classical convex relaxation algorithm introduced by Poulin and Hastings to approximate the free energy in quantum spin lattices. We identify a sufficient condition for its convergence, namely the decay of the effective interaction. We prove...
Stability of Stochastically Forced Solitons in the Korteweg-de Vries Equation
We study the stability and dynamics of solitons in the Korteweg-de Vries (KdV) equation in the presence of noise and deterministic forcing. The noise is space-dependent and statistically translation-invariant. We show that, for small forcing, solitons remain close to the family of...
