A leakage bound for confidence sets after black-box selection

Sayantan Banerjee

In many analyses the object reported at the end is not fixed in advance, but is chosen after a preliminary search over variables, subgroups, transformations, models or contrasts. Classical selective-inference methods are most effective when this search can be written as an explicit selection event. This note treats the...

The High-Energy Light Isotope eXperiment (HELIX) instrument

P.S. Allison · M. Baiocchi · J.J. Beatty · L. Beaufore · y 26 más

The HELIX detector is a balloon-borne instrument designed to measure the flux of light (Z < 11) cosmic-ray isotopes. In this paper we describe the initial configuration of HELIX, optimized for measurements in the energy range from approximately 0.2 GeV per nucleon to beyond 3 GeV per nucleon. In addition to a spectrome...

Determining Si/Al atomic ratios in particulate matter via quadrupole single-particle ICP-MS with combined unit-mass and bandpass resolution modes: a proof-of-concept study on Antarctic snow

M. Mataloni · A. Bazo · E. Bolea-Fernandez · A. Rua-Ibarz · y 6 más

Micrometer-scale mineral dust deposited in Antarctica represents a valuable archive for reconstructing atmospheric variability and for improving our understanding of dust-climate interactions. Among the various types of particle-specific information available, elemental ratios, such as the Si/Al atomic ratio, are espec...

Label-free fiber-optic cascade sensor for rapid and ultrasensitive serum folate quantification

Tongyuan, Kang · Lijuan, Yuan · Ruiduo, Wang · Man, Jiang · y 7 más

Fiber-optic biosensors based on interferometric structures have attracted considerable attention for rapid and label-free biomarker detection; however, achieving high sensitivity while maintaining practical applicability in complex biological matrices remains challenging. Here, we develop a tapered seven-core fiber (TS...

Pair Correlation Conjecture for the zeros of the Riemann zeta-function II: The Alternative Hypothesis

Daniel A. Goldston · Junghun Lee · Jordan Schettler · Ade Irma Suriajaya

In an earlier paper, we proved that Montgomery's Pair Correlation Conjecture (PCC) for zeros of the Riemann zeta-function can be used to prove without the assumption of the Riemann Hypothesis (RH) that asymptotically 100% of the zeros are both simple and on the critical line. This is based on a method of Gallagher and...

Differential graded algebras with divided powers and homotopy Lie algebras

Caradot, Antoine · Lin, Zongzhu

Given a commutative algebra $A$ and a quotient $A$-algebra $A/I$, we construct a resolution of $A/I$ as an $A$-module such that it is also a differential graded (dg) algebra with divided powers (PD). This construction makes use of symmetric tensors in the symmetric tensor category of dg $A$-modules and does not require...

Mycovirus prevalence is linked to increased virulence benefits in the fungal entomopathogen Beauveria bassiana

Fátima Rueda-Maíllo · Enrique Quesada-Moraga · María José García del Rosal · Inmaculada Garrido-Jurado

Numerous studies have reported the occurrence of mycoviruses in fungal strains of medical-veterinary, phytopathological, and entomological relevance, with an expanding literature on their phenotypic effects. However, their prevalence within fungal populations remains poorly understood. If mycoviral infections were to c...

Non-backtracking eigenvalues and eigenvectors of random regular graphs and hypergraphs

Xiangyi Zhu · Yizhe Zhu

The non-backtracking operator of a graph is a powerful tool in spectral graph theory and random matrix theory. Most existing results for the non-backtracking operator of a random graph concern only eigenvalues or top eigenvectors. In this paper, we take the first step in analyzing its bulk eigenvector behaviors. We dem...

Out of the picture: A multilevel framework of gender disparities in art

Eftychia Stamkou · Ana da Silva Pinho

Why do women artists remain a minority in museum collections and art markets, decades after becoming the majority in art schools? Talent does not explain it, since creative ability shows no meaningful gender differences, and audiences cannot tell an artist's gender from the work itself. The gap persists, we argue, beca...

Study of the mechanism by which HDAC3 regulates lipid synthesis in retinal ganglion cells by modulating SREBP-1c acetylation

Guangliang, Zhang · Xiaojun, Chen · Chunyan, Liu · Fengju, Guan · y 2 más

Diabetic retinopathy (DR) is characterized by early retinal neurodegeneration, with its pathological mechanisms closely linked to lipid metabolism disorders. Although histone deacetylase 3 (HDAC3) regulates systemic energy homeostasis, its role in lipid toxicity within DR neurons remains unclear. This study aimed to in...
