SASP: Strip-Aware Spatial Perception for Fine-Grained Bird Image Classification
Fine-grained bird image classification (FBIC) is not only of great significance for ecological monitoring and species identification, but also holds broad research value in the fields of image recognition and fine-grained visual modeling. Compared with general image classification tasks, FBIC poses more formidable challenges: 1) the differences in species size and imaging distance result in the varying sizes of birds presented in the images; 2) complex natural habitats often introduce strong ba…

AICO: Feature Significance Tests for Supervised Learning
The opacity of many supervised learning algorithms remains a key challenge, hindering scientific discovery and limiting broader deployment -- particularly in high-stakes domains. This paper develops model- and distribution-agnostic significance tests to assess the influence of input features in any regression or classification algorithm. Our method evaluates a feature's incremental contribution to model performance by masking its values across samples. Under the null hypothesis, the distributio…

Global Gauge Symmetries and Spatial Asymptotic Boundary Conditions in Yang-Mills theory
In Yang-Mills gauge theory on a Euclidean Cauchy surface the group of physical gauge symmetries carrying direct empirical significance is often believed to be $\mathcal{G}_\text{DES}=\mathcal{G}^I/\mathcal{G}^\infty_0$, where $\mathcal{G}^I$ is the group of boundary-preserving gauge symmetries and $\mathcal{G}^\infty_0$ is its subgroup of transformations that are generated by the constraints of the theory. These groups are identified respectively as the gauge transformations that become constan…

On admissibility in post-hoc hypothesis testing
The validity of classical hypothesis testing requires the significance level $α$ be fixed before any statistical analysis takes place. This is a stringent requirement. For instance, it prohibits updating $α$ during (or after) an experiment due to changing concern about the cost of false positives, or to reflect unexpectedly strong evidence against the null. Perhaps most disturbingly, witnessing a p-value $p\llα$ vs $p\leq α$ has no (statistical) relevance for any downstream decision-making.…

SO emission in the dynamically perturbed protoplanetary disks around CQ Tau and MWC 758
We report the serendipitous detection of the SO $J_N=6_5-5_4$ (219.949 GHz) rotational transition in archival Atacama Large Millimeter/submillimeter Array (ALMA) observations of the spiral hosting protoplanetary disks around CQ Tau (with $\approx4.9σ$ significance) and MWC 758 (with $\approx3.4σ$ significance). In the former, the SO emission comes in the shape of a ring, arises from the edge of the continuum cavity, and is qualitatively consistent, at the currently available spectral resoluti…

Implications of the evidence for direct $\mathbf{CP}$ violation in $D\to π^+π^-$ decays
The observation of CP violation in the difference of CP asymmetries between $D\to K^+K^-$ and $D\to π^+π^-$ has raised a debate whether the observed asymmetries can be regarded as a signal of physics beyond the standard model (SM). In this letter we show that the measured observables for $D\to ππ$ unambiguously imply a very large penguin contribution that is larger than $10\%$ of the amplitude for $D^0\toπ^+ π^-$ at a significance greater than $3.3σ$. We present arguments based only on u…

Certain geometric properties of planar harmonic mapping involving four parameter Wright functions
The primary aim of this paper is to construct harmonic mapping associated with four parameter Wright functions. Further sufficient conditions have been established so that this harmonic mapping satisfies geometric properties such as harmonic starlikeness and convexity. Moreover, we examine relation between several subclasses of family of harmonic close-to-convexity mappings. The results obtained in this paper are novel and their significance is illustrated by several consequences.

Addressing Bias in Algorithmic Solutions: Exploring Vertex Cover and Feedback Vertex Set
A typical goal of research in combinatorial optimization is to come up with fast algorithms that find optimal solutions to a computational problem. The process that takes a real-world problem and extracts a clean mathematical abstraction of it often throws out a lot of "side information" which is deemed irrelevant. However, the discarded information could be of real significance to the end-user of the algorithm's output. All solutions of the same cost are not necessarily of equal impact in the …

A Disentangled Representation Learning Framework for Low-altitude Network Coverage Prediction
The expansion of the low-altitude economy has underscored the significance of Low-Altitude Network Coverage (LANC) prediction for designing aerial corridors. While accurate LANC forecasting hinges on the antenna beam patterns of Base Stations (BSs), these patterns are typically proprietary and not readily accessible. Operational parameters of BSs, which inherently contain beam information, offer an opportunity for data-driven low-altitude coverage prediction. However, collecting extensive low-a…

Improving precision of A/B experiments using trigger intensity
In industry, online randomized controlled experiment (a.k.a. A/B experiment) is a standard approach to measure the impact of a causal change. These experiments have small treatment effect to reduce the potential blast radius. As a result, these experiments often lack statistical significance due to low signal-to-noise ratio. A standard approach for improving the precision (or reducing the standard error) focuses only on the trigger observations, where the output of the treatment and the control…

AGN with massive black holes have closer galactic neighbors: k-Nearest-Neighbor statistics of an unbiased sample of AGN at z~0.03
The large-scale environments of active galactic nuclei (AGN) reveal important information on the growth and evolution of supermassive black holes (SMBHs). Previous AGN clustering measurements using 2-point correlation functions have hinted that AGN with massive black holes preferentially reside in denser cosmic regions than AGN with less-massive SMBHs. At the same time, little to no dependence on the accretion rate is found. However, the significance of such trends have been limited. Here we pr…

Based on the received updates, multiple estimators determine the current safety-critical situations. Due to transmission errors and limited channel resources, the received status updates may not be fresh, resulting in the possibility of misunderstanding the current safety situation.

Impact of the history force on the motion of droplets in shaken liquids
Droplets and solid particles in unsteady flows are affected by the Basset-Boussinesq history force (BBH), in addition to stationary viscous friction, inertia, and gravity. The BBH is often neglected, not because this is generally justified, but because its inclusion in calculations is usually difficult. To assess the significance of BBH for particle dynamics, we revisit unsteady Stokes flows around spherical particles or droplets and derive from first-principles the analytical expressions for t…

The Ramsey number of the 4-cycle versus a book graph
Given positive integers $n$ and $k$, the book graph $B_n^{(k)}$ consists of $n$ copies of $K_{k+1}$ sharing a common $K_k$. The book graph is a common generalization of a star and a clique, which can be seen by taking $k=1$ and $n=1$ respectively. In addition, the Ramsey number of a book graph is closely related to the diagonal Ramsey number. Thus the study of extremal problems related to the book graph is of substantial significance. In this paper, we aim to investigate the Ramsey number $r(C_…

Transfer entropy is a widely used measure for quantifying directed information flows in complex systems. While the challenges of estimating transfer entropy for continuous data are well known, it has two major shortcomings that persist even for data of finite cardinality: it exhibits a substantial positive bias for sparse bin counts, and it has no clear means to assess statistical significance. By more precisely accounting for information content in finite data streams, we derive a transfer ent…

The direction of the dipole suggests an extragalactic origin of ultra-high-energy cosmic rays above those energies.

We analyze three solar modulation models: the force-field approximation (FFA), a time-, charge-, and rigidity-dependent FFA, and a three-dimensional numerical simulation based on the Parker transport equation. Based on AMS-02 latest antiproton data (2025), our results show that the significance of the DM signal is sensitive to the chosen modulation mo…

Unambiguous GeV gamma-rays from molecular clouds illuminated by particles diffusing from the adjacent supernova remnant G335.2+0.1 that is confined in an expanding bubble
We report the detection of GeV gamma-ray emission likely associated with supernova remnant (SNR) G335.2+0.1 and the finding of a molecular cloud ($\sim20$--$30^\prime$ in angular size) that is very likely in physical contact with the SNR and responsible for the gamma-ray emission. Using the 16.8 yr Fermi-LAT data, an extended emission, with a significance of 13.5 $σ$ and a radius 0.24° in 0.2--500 GeV in the uniform-disk model, was found to the adjacent east of the SNR. With archival Mopra CO…

New resonances at LHC
Due to the large QCD background, the tt spectroscopy is poorly doing at LHC with the exception of a toponium type candidate observed with high statistical significance by CMS. Our previous work offers an alternate interpretation of this narrow resonance as a Kaluza Klein graviton. For heavy scalars, following ATLAS, we describe how the top loop contribution to the gluon-gluon fusion mechanisms could produce a dip rather than a bump in the mass distribution, which further complicates searches fo…

LIQUIDating the Gallium Anomaly
The gallium anomaly has a global significance of greater than $5σ$. Most viable BSM solutions quickly run into strong tensions with reactor and solar neutrino data. We propose to use indium (${}^{115}\text{In}$) as a target as it offers a low threshold and reasonably high cross section. The neutrino-indium charged current cross section can be calibrated using the well-constrained solar ${}^{7}\text{Be}$ neutrino flux that lies very close in energy to the ${}^{51}\text{Cr}$ neutrino lines.
