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,

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 ...

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.

Boundary reduction formula [PDF]

open access: yes, 2002
An asymptotic theory is developed for general non-integrable boundary quantum field theory in 1+1 dimensions based on the Langrangean description. Reflection matrices are defined to connect asymptotic states and are shown to be related to the Green ...

Testing formula satisfaction [PDF]

open access: yes, 2012
We study the query complexity of testing for properties defined by read once formulae, as instances of massively parametrized properties, and prove several testability and non-testability results.

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.

Measurement and Analysis of Temperature-Dependent Optical Modal Gain in Single-Layer InAs/InP(100) Quantum-Dot Amplifiers in the 1.6- to 1.8-$\mu\hbox{m}$ Wavelength Range

open access: yesIEEE Photonics Journal, 2012
In this paper, measurements and analysis of the small-signal net modal gain of single-layer InAs/InP(100) quantum-dot (QD) optical amplifiers are presented. The amplifiers use only a single layer of InAs QDs on top of a thin InAs quantum well.

Finite-temperature reaction-rate formula: Finite volume system, detailed balance, $T \to 0$ limit, and cutting rules [PDF]

open access: yes, 1997
A complete derivation, from first principles, of the reaction-rate formula for a generic process taking place in a heat bath of finite volume is given. It is shown that the formula involves no finite-volume correction.
