Extensions of the Bonnet-Myers Theorem
In this paper, we present extensions of the classical Bonnet-Myers theorem for Riemannian manifolds with nonnegative Ricci curvature. Our results provide criteria for compactness and a method for estimating the diameter of such manifolds under general curvature conditions. As applications, we establish compactness theorems for manifolds whose Ricci curvature decays at polynomial or exponential rates.

Ultrafast giant enhancement of second harmonic generation in a strongly correlated cobaltite YbBaCo4O7
We report the observation of ultrafast photoinduced giant enhancement of optical second harmonic generation (SHG) efficiency in cobaltite YbBaCo4O7. Upon femtosecond pumping at energies above the band gap, the system exhibits an ultrafast enhancement in SHG intensity, reaching up to 60% higher than the initial value, then decays into a metastable state maintaining the enhancement. The enhancement scales linearly with pump fluence but shows no dependence on pump polarization. A pure electronic p…

Hyperon Pair Production at BESIII
This poster presents recent experimental findings from the BESIII experiment, including two categories of studies. Firstly, it reports the studies on the hyperon pair production in the processes $e^+e^- \to Λ\barΛ$, $Σ^+\barΣ^-$, $Σ^0\barΣ^0$, $Ξ^0\barΞ^0$ and $Ξ^-\barΞ^+$. The Born cross sections for these processes are measured at center-of-mass energies ranging from $3.5$ to $4.9$ GeV. For the first time, evidence for the decays $ψ(3770)\toΛ\barΛ$ and $Ξ^-\barΞ^+$ is found. Se…

Geodesics in Quantum Gravity
We investigate the motion of test particles in quantum-gravitational backgrounds by introducing the concept of q--desics, quantum-corrected analogs of classical geodesics. Unlike standard approaches that rely solely on the expectation value of the spacetime metric, our formulation is based on the expectation value of quantum operators, such as the the affine connection-operator. This allows us to capture richer geometric information. We derive the q--desic equation using both Lagrangian and Ham…

Network Community Detection and Novelty Scoring Reveal Underexplored Hub Genes in Rheumatoid Arthritis
Understanding the modular structure and central elements of complex biological networks is critical for uncovering system-level mechanisms in disease. Here, we constructed weighted gene co-expression networks from bulk RNA-seq data of rheumatoid arthritis (RA) synovial tissue, using pairwise correlation and a percolation-guided thresholding strategy. Community detection with Louvain and Leiden algorithms revealed robust modules, and node-strength ranking identified the top 50 hub genes globally…

GastroViT: A Vision Transformer Based Ensemble Learning Approach for Gastrointestinal Disease Classification with Grad CAM & SHAP Visualization
The gastrointestinal (GI) tract of humans can have a wide variety of aberrant mucosal abnormality findings, ranging from mild irritations to extremely fatal illnesses. Prompt identification of gastrointestinal disorders greatly contributes to arresting the progression of the illness and improving therapeutic outcomes. This paper presents an ensemble of pre-trained vision transformers (ViTs) for accurately classifying endoscopic images of the GI tract to categorize gastrointestinal problems and …

Sorry, liebes @….
Aber ist dieses Bild in der zentralen Nachrichtensendung des ÖRR würdig? Der arme Professor ist rot wie ein Krebs, weil er sich vermutlich selbst filmt, aber keinen Weißabgleich macht.
Früher hätte man ein Team dorthin geschickt, was natürlich deutlich Kosten verursacht. Mich gruseln solche Bilder, weil ich andere Qualitätsstandards kannte.…

World's First Authenticated Satellite Pseudorange from Orbit
Cryptographic Ranging Authentication is here! We present initial results on the Pulsar authenticated ranging service broadcast from space with Pulsar-0 utilizing a recording taken at Xona headquarters in Burlingame, CA. No assumptions pertaining to the ownership or leakage of encryption keys are required. This work discusses the Pulsar watermark design and security analysis. We derive the Pulsar watermark's probabilities of missed detection and false alarm, and we discuss the required receiver …
