Distinct EEG Features and Sleep/Wake Behaviour Predict Anxiety Phenotypes in Mice

Journal of Sleep Research, EarlyView.
ABSTRACT Preoperative anxiety is a prevalent clinical problem linked to adverse surgical outcomes, including elevated pain, prolonged hospital stays and increased risk of postoperative delirium. Current assessments rely heavily on subjective measures, necessitating objective biomarkers.

$G$-nilpotent units of commutative group rings [PDF]

, 2012
summary:Suppose $R$ is a commutative unital ring and $G$ is an abelian group. We give a general criterion only in terms of $R$ and $G$ when all normalized units in the commutative group ring $RG$ are $G$-nilpotent.

Ideal Dasar Prima Dalam Aljabar Atas Suatu Ring Komutatif

Jurnal Fourier, 2018
Definisi ideal dasar dan ideal bebas dalam aljabar bebas atas ring komutatif dengan elemen satuan adalah ekuivalen. Namun, ideal dasar dalam suatu aljabar tak bebas belum tentu merupakan ideal bebas, sementara ideal bebas pasti ideal dasar.

Aggregation and the Structure of Value

Noûs, EarlyView.
ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

Hidden constructions in abstract algebra: Krull dimension of distributive lattices and commutative rings [PDF]

, 2003
We present constructive versions of Krull's dimension theory for commutative rings and distributive lattices. The foundations of these constructive versions are due to Joyal, Espanol and the authors.

The Structure of Tripotent Graph of Certain Commutative Rings

Al-Rafidain Journal of Computer Sciences and Mathematics
In this paper, we characterize the texture of tripotent graph of the ring, which is associated by tripotent element of a ring such that, for every two distinct vertices; and then, their adjacent if and only if.

On computing local monodromy and the numerical local irreducible decomposition

Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract Similarly to the global case, the local structure of a holomorphic subvariety at a given point is described by its local irreducible decomposition. Geometrically, the key requirement for obtaining a local irreducible decomposition is to compute the local monodromy action of a generic linear projection at the given point, which is always well ...

A commutative version of the group ring [PDF]

We construct a commutative version of the group ring and show that it allows one to translate questions about the normal generation of groups into questions about the generation of ideals in commutative rings.

The Bordalo order on a commutative ring [PDF]

, 1999
summary:If $R$ is a commutative ring with identity and $\leq$ is defined by letting $a\leq b$ mean $ab=a$ or $a=b$, then $(R,\leq)$ is a partially ordered ring.
