A non-planar two-loop three-point function beyond multiple polylogarithms

Journal of High Energy Physics, 2017
We consider the analytic calculation of a two-loop non-planar three-point function which contributes to the two-loop amplitudes for t t ¯ $$ t\overline{t} $$ production and γγ production in gluon fusion through a massive top-quark loop.

One-loop open-string integrals from differential equations: all-order α′-expansions at n points

Journal of High Energy Physics, 2020
We study generating functions of moduli-space integrals at genus one that are expected to form a basis for massless n-point one-loop amplitudes of open superstrings and open bosonic strings.

Multi-variable integration with a neural network

Journal of High Energy Physics, 2023
In this article we present a method for automatic integration of parametric integrals over the unit hypercube using a neural network. The method fits a neural network to the primitive of the integrand using a loss function designed to minimize the ...

Multiple extremal integrals

Electronic Journal of Probability
We introduce the notion of multiple extremal integrals as an extension of single extremal integrals, which have played important roles in extreme value theory. The multiple extremal integrals are formulated in terms of a product-form random sup measure derived from the $α$-Fréchet random sup measure. We establish a LePage-type representation similar to

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

Evaluating Feynman integrals by the hypergeometry

Nuclear Physics B, 2018
The hypergeometric function method naturally provides the analytic expressions of scalar integrals from concerned Feynman diagrams in some connected regions of independent kinematic variables, also presents the systems of homogeneous linear partial ...

Prognosis of Long‐Term Continuous Renal Replacement Therapy and the Impact of Combined Continuous Intravenous Sodium Infusion Therapy

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Master integrals for O $$ \mathcal{O} $$ (αα s ) corrections to H → ZZ *

Journal of High Energy Physics, 2022
We present analytic results for all the Feynman integrals relevant for O $$ \mathcal{O} $$ (αα s ) virtual corrections to H → ZZ * decay. We use the method of differential equations to solve the master integrals while keeping the full dependence on the ...
