Study of the doubly charmed tetraquark [Formula: see text]. [PDF]

open access: yesNature Communications, 2021
Quantum chromodynamics, the theory of the strong force, describes interactions of coloured quarks and gluons and the formation of hadronic matter. Conventional hadronic matter consists of baryons and mesons made of three quarks and quark-antiquark pairs,

Formulas! Formulas! Everywhere!

open access: yesOhio Journal of School Mathematics, 2022
This article describes activities that can be used to introduce the concepts of perimeter and area with conceptual understanding for students in grades 4 through 9. The transformations of reflection and rotation are used to build this understanding.

Blood Performance: A New Formula for Fish Growth and Health

open access: yesBiology, 2021
Simple Summary The use of haematological and blood biochemistry parameters has proven to be effective and repeatable ways to monitor fish health. Testing these parameters is becoming more common in aquaculture studies. Further, it is widely accepted that

Comparison of gut microbiota in exclusively breast-fed and formula-fed babies: a study of 91 term infants

open access: yesScientific Reports, 2020
To compare gut microbiota of healthy infants that were exclusively breast-fed or formula-fed, we recruited 91 infants, who were assigned into three different groups and fed by breast milk (30 babies), formula A (30 babies) or formula B (31 babies ...

Database-independent molecular formula annotation using Gibbs sampling through ZODIAC

open access: yesNature Machine Intelligence, 2020
The confident high-throughput identification of small molecules is one of the most challenging tasks in mass spectrometry-based metabolomics. Annotating the molecular formula of a compound is the first step towards its structural elucidation.

A Universal Action Formula [PDF]

open access: yes, 1996
A universal formula for an action associated with a noncommutative geometry, defined by a spectal triple $(\Ac ,\Hc ,D)$, is proposed. It is based on the spectrum of the Dirac operator and is a geometric invariant.

High-Speed Correlation and Equalization Using a Continuously Tunable All-Optical Tapped Delay Line

open access: yesIEEE Photonics Journal, 2012
We demonstrate a reconfigurable high-speed optical tapped delay line (TDL), enabling several fundamental real-time signal processing functions such as correlation (for pattern search) and equalization.

Generalized Goldberg Formula [PDF]

open access: yes, 2016
In this paper we prove a useful formula for the graded commutator of the Hodge codifferential with the left wedge multiplication by a fixed $p$-form acting on the de Rham algebra of a Riemannian manifold.

Formulaic language [PDF]

open access: yesLanguage Teaching, 2006
Creating a timeline for formulaic language is far from simple, because several partially independent lines of research have contributed to the emerging picture. Each exhibits cycles of innovation and consolidation over time: domains take a leading role in developing new knowledge and then fall back, while another area comes to the fore.
