Determinant Theory for Neutrosophic Hypersoft Rough Fuzzy Matrices [PDF]

open access: yesNeutrosophic Sets and Systems
In this study, we examine the determinant theory associated with Neutrosophic Hypersoft Rough Fuzzy Matrices (NHSRFMs) and investigate several of their structural properties.

Adjointness in Foundations [PDF]

open access: yesDialectica, 1969
This paper is a reprint of \textit{F. W. Lawvere} [Dialectica 23, 281--296 (1969; Zbl 0341.18002)] with the author's new commentary. The paper presented revolutionary applications of adjointness in logic and foundations. Prior to this work, the intimate connections between category theory and logical research were not obvious.

Source attribution of particulate matter pollution over North China with the adjoint method

open access: yesEnvironmental Research Letters, 2015
We quantify the source contributions to surface PM2.5 (fine particulate matter) pollution over North China from January 2013 to 2015 using the GEOS-Chem chemical transport model and its adjoint with improved model horizontal resolution (1/4° × 5/16°) and

Determinant Theory of Quadri-Partitioned Neutrosophic Fuzzy Matrices and its Application to Multi-Criteria Decision-Making Problems [PDF]

open access: yesNeutrosophic Sets and Systems
We propose a refined method to compute the determinant of matrices with a higher number of rows and columns. Furthermore, an algorithm is developed to address decision-making problems based on QPNFMs.

Premature Deaths in Brazil Associated With Long‐Term Exposure to PM2.5 From Amazon Fires Between 2016 and 2019

open access: yesGeoHealth, 2020
Amazonian deforestation from slash‐and‐burn practices is a significant contributor to biomass burning within Brazil. Fires emit carbonaceous aerosols that negatively impact human health by increasing fine particulate matter (PM2.5) exposure.

Temporal and spatial variability in the aviation NOx-related O3 impact

open access: yesEnvironmental Research Letters, 2013
Aviation NO _x emissions promote tropospheric ozone formation, which is linked to climate warming and adverse health effects. Modeling studies have quantified the relative impact of aviation NO _x on O _3 in large geographic regions.

Fully turbulent discrete adjoint solver for non-ideal compressible flow applications

open access: yesJournal of the Global Power and Propulsion Society, 2017
Non-Ideal Compressible Fluid-Dynamics (NICFD) has recently been established as a sector of fluid mechanics dealing with the flows of dense vapors, supercritical fluids, and two-phase fluids, whose properties significantly depart from those of the ideal ...

On the Self-Adjointness of H+A∗+A [PDF]

open access: yesMathematical Physics, Analysis and Geometry, 2020
AbstractLet $H:\text {dom}(H)\subseteq \mathfrak {F}\to \mathfrak {F}$ H : dom ( H ) ⊆ F → F be self-adjoint and let $A:\text {dom}(H)\to \mathfrak {F}$

Adjoints of matroids

open access: yesAdvances in Applied Mathematics
We show that an adjoint of a loopless matroid is connected if and only if it itself is connected. Our first goal is to study the adjoint of modular matroids. We prove that a modular matroid has only one adjoint (up to isomorphism) which can be given by its opposite lattice, and proceed to present some alternative characterizations of modular matroids ...

Induction, Coinduction, and Adjoints

open access: yesElectronic Notes in Theoretical Computer Science, 2003
We investigate the reasons for which the existence of certain right adjoints implies the existence of some final coalgebras, and vice-versa. In particular we prove and discuss the following theorem which has been partially available in the literature: let F G be a pair of adjoint functors, and suppose that an initial algebra F(X) of the functor H(Y ...
