Gravitational Lensing and Shadow of a Black Hole in Bumblebee Gravity

Published:Dec 31, 2025 17:43
1 min read
ArXiv

Analysis

This paper explores the strong gravitational lensing and shadow properties of a black hole within the framework of bumblebee gravity, which incorporates a global monopole charge and Lorentz symmetry breaking. The study aims to identify observational signatures that could potentially validate or refute bumblebee gravity in the strong-field regime by analyzing how these parameters affect lensing observables and shadow morphology. This is significant because it provides a way to test alternative theories of gravity using astrophysical observations.
Reference

“The results indicate that both the global monopole charge and Lorentz-violating parameters significantly influence the photon sphere, lensing observables, and shadow morphology, potentially providing observational signatures for testing bumblebee gravity in the strong-field regime.”

Causal Physiological Representation Learning for Robust ECG Analysis

Published:Dec 31, 2025 02:08
1 min read
ArXiv

Analysis

This paper addresses the vulnerability of deep learning models for ECG diagnosis to adversarial attacks, particularly those mimicking biological morphology. It proposes a novel approach, Causal Physiological Representation Learning (CPR), to improve robustness without sacrificing efficiency. The core idea is to leverage a Structural Causal Model (SCM) to disentangle invariant pathological features from non-causal artifacts, leading to more robust and interpretable ECG analysis.
Reference

“CPR achieves an F1 score of 0.632 under SAP attacks, surpassing Median Smoothing (0.541 F1) by 9.1%.”

Fast ROI Triggering with Autoencoders in Optical TPCs

Published:Dec 30, 2025 15:28
1 min read
ArXiv

Analysis

This paper presents a novel approach for real-time data selection in optical Time Projection Chambers (TPCs), a crucial technology for rare-event searches. The core innovation lies in using an unsupervised, reconstruction-based anomaly detection strategy with convolutional autoencoders trained on pedestal images. This method allows for efficient identification of particle-induced structures and extraction of Regions of Interest (ROIs), significantly reducing the data volume while preserving signal integrity. The study's focus on the impact of training objective design and its demonstration of high signal retention and area reduction are particularly noteworthy. The approach is detector-agnostic and provides a transparent baseline for online data reduction.
Reference

“The best configuration retains (93.0 +/- 0.2)% of reconstructed signal intensity while discarding (97.8 +/- 0.1)% of the image area, with an inference time of approximately 25 ms per frame on a consumer GPU.”

ECG Generalization with Morphology-Rhythm Disentanglement

Published:Dec 29, 2025 10:14
1 min read
ArXiv

Analysis

This paper addresses the challenge of generalizing ECG classification across different datasets, a crucial problem for clinical deployment. The core idea is to disentangle morphological features and rhythm dynamics, which helps the model to be less sensitive to distribution shifts. The proposed ECG-RAMBA framework, combining MiniRocket, HRV, and a bi-directional Mamba backbone, shows promising results, especially in zero-shot transfer scenarios. The introduction of Power Mean pooling is also a notable contribution.
Reference

“ECG-RAMBA achieves a macro ROC-AUC ≈ 0.85 on the Chapman--Shaoxing dataset and attains PR-AUC = 0.708 for atrial fibrillation detection on the external CPSC-2021 dataset in zero-shot transfer.”

Eojeol-Based Constituency Parsing for Korean

Published:Dec 27, 2025 06:12
1 min read
ArXiv

Analysis

This paper addresses the challenge of constituency parsing in Korean, specifically focusing on the choice of terminal units. It argues for an eojeol-based approach (eojeol being a Korean word unit) to avoid conflating word-internal morphology with phrase-level syntax. The paper's significance lies in its proposal for a more consistent and comparable representation of Korean syntax, facilitating cross-treebank analysis and conversion between constituency and dependency parsing.

Morphology-Preserving Holotomography for 3D Organoid Analysis

Published:Dec 27, 2025 06:07
1 min read
ArXiv

Analysis

This paper presents a novel method, Morphology-Preserving Holotomography (MP-HT), to improve the quantitative analysis of 3D organoid dynamics using label-free imaging. The key innovation is a spatial filtering strategy that mitigates the missing-cone artifact, a common problem in holotomography. This allows for more accurate segmentation and quantification of organoid properties like dry-mass density, leading to a better understanding of organoid behavior during processes like expansion, collapse, and fusion. The work addresses a significant limitation in organoid research by providing a more reliable and reproducible method for analyzing their 3D dynamics.
Reference

“The results demonstrate consistent segmentation across diverse geometries and reveal coordinated epithelial-lumen remodeling, breakdown of morphometric homeostasis during collapse, and transient biophysical fluctuations during fusion.”

Published:Dec 27, 2025 01:10
1 min read
ArXiv

Analysis

This paper introduces Bright-4B, a large-scale foundation model designed to segment subcellular structures directly from 3D brightfield microscopy images. This is significant because it offers a label-free and non-invasive approach to visualize cellular morphology, potentially eliminating the need for fluorescence or extensive post-processing. The model's architecture, incorporating novel components like Native Sparse Attention, HyperConnections, and a Mixture-of-Experts, is tailored for 3D image analysis and addresses challenges specific to brightfield microscopy. The release of code and pre-trained weights promotes reproducibility and further research in this area.
Reference

“Bright-4B produces morphology-accurate segmentations of nuclei, mitochondria, and other organelles from brightfield stacks alone--without fluorescence, auxiliary channels, or handcrafted post-processing.”

Double-Double Radio Galaxies: A New Accretion Model

Published:Dec 26, 2025 23:47
1 min read
ArXiv

Analysis

This paper proposes a novel model for the formation of double-double radio galaxies (DDRGs), suggesting that the observed inner and outer jets are linked by continuous accretion, even during the quiescent phase. The authors argue that the black hole spin plays a crucial role, with jet formation being dependent on spin and the quiescent time correlating with the subsequent jet duration. This challenges the conventional view of independent accretion events and offers a compelling explanation for the observed correlations in DDRGs.
Reference

“The authors show that a correlation between the quiescent time and the inner jet time may exist, which they interpret as resulting from continued accretion through the quiescent jet phase.”

    Analysis

    This paper investigates how the stiffness of a surface influences the formation of bacterial biofilms. It's significant because biofilms are ubiquitous in various environments and biomedical contexts, and understanding their formation is crucial for controlling them. The study uses a combination of experiments and modeling to reveal the mechanics behind biofilm development on soft surfaces, highlighting the role of substrate compliance, which has been previously overlooked. This research could lead to new strategies for engineering biofilms for beneficial applications or preventing unwanted ones.

    Numerical Twin for EEG Oscillations

    Published:Dec 25, 2025 19:26
    2 min read
    ArXiv

    Analysis

    This paper introduces a novel numerical framework for modeling transient oscillations in EEG signals, specifically focusing on alpha-spindle activity. The use of a two-dimensional Ornstein-Uhlenbeck (OU) process allows for a compact and interpretable representation of these oscillations, characterized by parameters like decay rate, mean frequency, and noise amplitude. The paper's significance lies in its ability to capture the transient structure of these oscillations, which is often missed by traditional methods. The development of two complementary estimation strategies (fitting spectral properties and matching event statistics) addresses parameter degeneracies and enhances the model's robustness. The application to EEG data during anesthesia demonstrates the method's potential for real-time state tracking and provides interpretable metrics for brain monitoring, offering advantages over band power analysis alone.
    Reference

    “The method identifies OU models that reproduce alpha-spindle (8-12 Hz) morphology and band-limited spectra with low residual error, enabling real-time tracking of state changes that are not apparent from band power alone.”
