Order-cushioned refinements and normality [PDF]

open access: yesProceedings of the American Mathematical Society, 1982
The authors use the notions of order-cushioned covers and weak 0-covers to obtain the following result. THEOREM. A space X is collectionwise normal iff every weak 6-cover of X has an order-cushioned open refinement. Similar characterizations are obtained for normal, countably paracompact spaces and analogous embedding theorems are shown.

Exploring the flavor structure of quarks and leptons with reinforcement learning

open access: yesJournal of High Energy Physics, 2023
We propose a method to explore the flavor structure of quarks and leptons with reinforcement learning. As a concrete model, we utilize a basic value-based algorithm for models with U(1) flavor symmetry.

Two Features of the GINAR(1) Process and Their Impact on the Run-Length Performance of Geometric Control Charts

open access: yesEntropy, 2023
The geometric first-order integer-valued autoregressive process (GINAR(1)) can be particularly useful to model relevant discrete-valued time series, namely in statistical process control.

2020 global reassessment of the neutrino oscillation picture

open access: yesJournal of High Energy Physics, 2021
We present an updated global fit of neutrino oscillation data in the simplest three-neutrino framework. In the present study we include up-to-date analyses from a number of experiments.

Walks, Partitions, and Normal Ordering [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2015
We describe the relation between graph decompositions into walks and the normal ordering of differential operators in the $n$-th Weyl algebra. Under several specifications, we study new types of restricted set partitions, and a generalization of Stirling numbers, which we call the $\lambda$-Stirling numbers.

Crucial Dependence of ``Precarious'' and ``Autonomous'' phi^4s Upon the Normal-ordering Mass [PDF]

open access: yes, 1999
Using the Gaussian wave-functional approach with the normal-ordering renormalization prescription, we show that for the (3+1)-dimensional massive lambda phi^4 theory, ``precarious'' and ``autonomous'' phi^4s can exist if and only if the normal-ordering ...

NORMALLY ORDERED SEMIGROUPS [PDF]

open access: yesGlasgow Mathematical Journal, 2008
AbstractIn this paper we introduce the notion of normally ordered block-group as a natural extension of the notion of normally ordered inverse semigroup considered previously by the author. We prove that the classNOSof all normally ordered block-groups forms a pseudovariety of semigroups and, by using the Munn representation of a block-group, we deduce

Constraining visible neutrino decay at KamLAND and JUNO

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We study visible neutrino decay at the reactor neutrino experiments KamLAND and, JUNO. Assuming the Majoron model of neutrino decay, we obtain constraints on the couplings between Majoron and neutrino as well as on the lifetime/mass of the most massive ...

Combined sensitivity of JUNO and KM3NeT/ORCA to the neutrino mass ordering

open access: yesJournal of High Energy Physics, 2022
This article presents the potential of a combined analysis of the JUNO and KM3NeT/ORCA experiments to determine the neutrino mass ordering. This combination is particularly interesting as it significantly boosts the potential of either detector, beyond ...

Continuous review inventory model with lost sale reduction and ordering cost dependent on lead time for the mixtures of distributions [PDF]

open access: yesYugoslav Journal of Operations Research, 2021
We consider a continuous review inventory system for inventory model involving lost sales reduction through capital investment cost function and the reduction of lead time further which reduces the ordering cost.
