How are the #Perseids 2025 doing so far? Here are the current live plots from two different video camera network data published by https://globalmeteornetwork.org/flux/ and https://meteorflux.org/ resp. and from radio echo data published in https://jpn.iprmo.org/post/flash/per-2025.html - the peak is still ahead (and should arrive in a few hours).

Data Driven Discovery of Emergent Dynamics in Reaction Diffusion Systems from Sparse and Noisy Observations
Data-driven discovery of emergent dynamics is gaining popularity, particularly in the context of reaction-diffusion systems. These systems are widely studied across various fields, including neuroscience, ecology, epidemiology, and several other subject areas that deal with emergent dynamics. A current challenge in the discovery process relates to system identification when there is no prior knowledge of the underlying physics. We attempt to address this challenge by learning Soft Artificial Li…

Climate change made heat and dryness that fueled Iberian wildfires 40 times more likely, study finds
The extremely hot, dry and windy conditions, which fueled one of the Iberian Peninsula's most destructive wildfire seasons in recorded history, were 40 times more likely due to climate change, according to a study released Thursday.

Resource-Efficient Glioma Segmentation on Sub-Saharan MRI
Gliomas are the most prevalent type of primary brain tumors, and their accurate segmentation from MRI is critical for diagnosis, treatment planning, and longitudinal monitoring. However, the scarcity of high-quality annotated imaging data in Sub-Saharan Africa (SSA) poses a significant challenge for deploying advanced segmentation models in clinical workflows. This study introduces a robust and computationally efficient deep learning framework tailored for resource-constrained settings. We leve…

Average Contraction Coefficients of Quantum Channels
The data-processing inequality ensures quantum channels reduce state distinguishability, with contraction coefficients quantifying optimal bounds. However, these can be overly optimistic and not representative of the usual behavior. We study how noise contracts distinguishability of `typical' states, beyond the worst-case. To that end, we introduce and study a family of moments of contraction for quantum divergences, which interpolate between the worst-case contraction coefficient of a channel …

Architecture and FPGA Implementation of Digital Time-to-Digital Converter for Sensing Applications
Many application domains face the challenges of high-power consumption and high computational demands, especially with the advancement in embedded machine learning and edge computing. Designing application-specific circuits is crucial to reducing hardware complexity and power consumption. In these perspectives, this paper presents the design of a Digital Time-to-Digital converter (DTDC) based on multiple delay line topologies. The DTDC is implemented in VHDL for the Xilinx Artix-7 AC701 FPGA de…

Analysis of Pantheon+ supernova data suggests evidence of sign-changing pressure of the cosmological fluid
In this work, we revisit/reinterpret/extend the model-independent analysis method (which we now call spread - luminosity distance fitting, spread-LDF) from our previous work. We apply it to the updated supernova type Ia catalogue, Pantheon+ and recent GRB compilations. The procedure allows us, using only FLRW assumption, to construct good approximations for expansion history of the universe, re-confirming its acceleration to be a robust feature. When we also assume General Relativity ("GR"), we…
