Adaptation potential of Neotropical montane oaks to drought events: Wood anatomy sensitivity in Quercus delgadoana and Quercus meavei

open access: yesFunctional Ecology, Volume 37, Issue 7, Page 2040-2055, July 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate and local water availability are major evolutionary drivers of adaptive variation and plasticity in the hydraulic architecture of Tropical Montane Cloud Forest (TMCF) tree species.

Singularist Semirealism [PDF]

open access: yesThe British Journal for the Philosophy of Science, 2013
Abstract: This paper proposes to carve out a new position in the scientific realism/antirealism debate and argue that it captures some of the most important realist and some of the most important antirealist considerations. The view, briefly stated, is that there is always a fact of the matter about whether the singular statements science gives us are ...

APOE ε4 is associated with earlier symptom onset in LOAD but later symptom onset in EOAD

open access: yesAlzheimer's &Dementia, Volume 19, Issue 5, Page 2212-2217, May 2023., 2023
Abstract Background We studied the effect of apolipoprotein E (APOE) ε4 status and sex on age of symptom onset (AO) in early‐ (EO) and late‐ (LO) onset Alzheimer's disease (AD). Method A total of 998 EOAD and 2562 LOAD participants from the National Alzheimer's Coordinating Center (NACC) were included.

Valuation semirings [PDF]

open access: yesJournal of Algebra and Its Applications, 2018
The main scope of this paper is to introduce the valuation semirings in general and discrete valuation semirings in particular. In order to do that, first, we define valuation maps and investigate them. Then we define valuation semirings with the help of valuation maps and prove that a multiplicatively cancellative semiring is a valuation semiring if ...

Commutativity of MA-Semirings with Involution through Generalized Derivations

open access: yesJournal of Mathematics, 2020
In this paper, we study the generalized derivations of MA-semirings with involution. We discuss some differential identities satisfied by the generalized derivations which force the semirings with involution to be commutative.

Characterizations of Regular Ordered Semirings by Ordered Quasi-Ideals

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2016
We introduce the notion of an ordered quasi-ideal of an ordered semiring and show that ordered quasi-ideals and ordered bi-ideals coincide in regular ordered semirings.

Thermodynamic semirings

open access: yesJournal of Noncommutative Geometry, 2014
The Witt construction describes a functor from the category of Rings to the category of characteristic 0 rings. It is uniquely determined by a few associativity constraints which do not depend on the types of the variables considered, in other words, by integer polynomials.

Centrally Essential Semirings

open access: yesLobachevskii Journal of Mathematics, 2022
A semiring is said to be centrally essential if for every non-zero element $x$, there exist two non-zero central elements $y, z$ with $xy = z$. We give some examples of non-commutative centrally essential semirings and describe some properties of additively cancellative centrally essential semirings.
