PhotonIDs: ML-Powered Photon Identification System for Dark Count Elimination
Reliable single photon detection is the foundation for practical quantum communication and networking. However, today's superconducting nanowire single photon detector(SNSPD) inherently fails to distinguish between genuine photon events and dark counts, leading to degraded fidelity in long-distance quantum communication. In this work, we introduce PhotonIDs, a machine learning-powered photon identification system that is the first end-to-end solution for real-time discrimination between photons…

Although numerous dynamical techniques have been developed to estimate the total dark matter halo mass of the Milky Way, it remains poorly constrained, with typical systematic uncertainties of 0.3 dex. In this study, we apply a neural network-based approach that achieves high mass precision without several limitations that have affected past approaches; for example, we do not assume dynamical equilibrium, nor do we assume that neighboring galaxies are bound satellites.

A more interpretable regression model for count data with excess of zeros
Count data are common in medical research. When these data have more zeros than expected by the most used count distributions, it is common to employ a zero-inflated regression model. However, the interpretability of these models is much lower than the most used count regression models. In this work, we introduce a more interpretable regression model for count data with excess of zeros based on a reparameterization of the zero-inflated Poisson distribution. We discuss inferential and diagnostic…

Evaluating sampling strategies for effective detection of African swine fever in the growing pig population in the U.S
Early detection of African swine fever virus (ASFV) is critical to preventing widespread epidemics. However, the effectiveness of within-farm sampling remains to be examined, particularly during the early phase of an outbreak when disease prevalence is low, animals may be asymptomatic, or clinical signs are masked by co-circulating diseases. This study assessed four sampling strategies for detecting ASFV-infected animals in suspected growing pig farms within the first 14 days of the introductio…

Dark Signals in the Brain: Augment Brain Network Dynamics to the Complex-valued Field
Recordings of brain activity, such as functional MRI (fMRI), provide low-dimensional, indirect observations of neural dynamics evolving in high-dimensional, unobservable spaces. Embedding observed brain dynamics into a higher-dimensional representation may help reveal functional organization, but precisely how remains unclear. Hamiltonian mechanics suggests that, by introducing an additional dimension of conjugate momenta, the dynamical behaviour of a conservative system can be formulated in a …

Reduction principles for proper actions
We study the core of a proper action by a Lie group $G$ on a smooth manifold $M$, extending the construction for $G$ compact by Skjelbred and Straume. Moreover, we show that many properties of a proper $G$-action on $M$ are determined by the action of a group $G'$ on the corresponding core $_cM$. We say that such properties admit a reduction principle. In particular, we prove that a proper isometric $G$-action on $M$ is polar (resp. hyperpolar) if and only if the $G'$-action on $_cM$ is polar (…

We present the first complete next-to-leading-order analysis of a Yukawa system within the framework of asymptotically safe quantum gravity.

In addition, we introduce a novel approach to estimate systematic uncertainties by simulating the impact of neglected higher-order contributions. We demonstrate that quantum g…

Realization of a Chiral Photonic-Crystal Cavity with Broken Time-Reversal Symmetry
Light-matter interactions in chiral cavities offer a compelling route to manipulate material properties by breaking fundamental symmetries such as time-reversal symmetry. However, only a limited number of chiral cavity implementations exhibiting broken time-reversal symmetry have been demonstrated to date. These typically rely on either the application of strong magnetic fields, circularly polarized Floquet driving, or the hybridization of cavity modes with matter excitations in the ultrastrong…

Effects of Bethe-Heitler pair production in ultraluminous X-ray sources
Some black holes in X-ray binaries accrete at rates far above the Eddington limit. In this supercritical regime, photons are trapped in a radiation-dominated, geometrically thick disk.

These conditions suppress primary relativistic electrons within the transparent funnel along the black hole's spin axis. We show that high…

For the connected correlator, variance reductions grow systematically with the time separation and …

Non-Existence of Solutions for a Fourth-Order Structurally Damped Equation Under Nonlinear Memory Effect
In this paper, we study a mixed wave-plate equation with rotational inertia, fractional damping and memory non-linearity. This research is a non-existence counterpart to a paper by D'Abbicco and Longen, in search of the critical exponent for the global in-time existence of small data solutions to the Cauchy problem for a mixed wave-plate equation, with a rotational inertia and a non-integer dissipation term and a memory-type non-linearity. We employ a modified test function argument to show tha…

Large circular dichroism in the total photoemission yield of free chiral nanoparticles created by a pure electric dipole effect
Spectroscopic techniques that are sensitive to molecular chirality are important analytical tools to quantitatively determine enantiomeric excess and purity of chiral molecular samples. Many chiroptical processes however produce weak enantio-specific asymmetries due to their origin relying on weak magnetic dipole or electric quadrupole effects. Photoelectron circular dichroism (PECD) in contrast, is an intense effect, that is fully contained in the electric dipole description of light matter in…

Alzheimer's Clinical Research Data via R Packages: the alzverse
Sharing clinical research data is essential for advancing research in Alzheimer's disease (AD) and other therapeutic areas. However, challenges in data accessibility, standardization, documentation, usability, and reproducibility continue to impede this goal. In this article, we highlight the advantages of using R packages to overcome these challenges using two examples. The A4LEARN R package includes data from a randomized trial (the Anti-Amyloid Treatment in Asymptomatic Alzheimer's [A4] stud…

First highly pathogenic avian influenza outbreak in a commercial farm in Brazil: outbreak timeline, control actions, risk analysis, and transmission modeling
On May 15, 2025, Brazil reported its first highly pathogenic avian influenza (HPAI) outbreak in a commercial poultry breeder farm in Montenegro, Rio Grande do Sul. This study presents the outbreak timeline, control measures, along with spatial risk assessment and epidemiological model used to simulate detection delays. The transmission model considered Susceptible Exposed Infected Recovered Dead farm statuses to simulate within farm and between farm dynamics under 3 day, 5 day, and 10 day detec…
