Jordan Derivations of some extension algebras [PDF]

arXiv, 2013
In this paper, we mainly study Jordan derivations of dual extension algebras and those of generalized one-point extension algebras. It is shown that every Jordan derivation of dual extension algebras is a derivation. As applications, we obtain that every Jordan generalized derivation and every generalized Jordan derivation on dual extension algebras ...

Cardiac Vagal Efficiency Is Enhanced by Percutaneous Auricular Neurostimulation in Adolescents With Nausea: Moderation by Antidepressant Drug Exposure

Neurogastroenterology &Motility, Volume 37, Issue 5, May 2025.
Acute enhancement of cardiac vagal efficiency (VE) is demonstrated with active compared to sham percutaneous electrical nerve field stimulation (PENFS). This effect is not found in children chronically exposed to antidepressants with anticholinergic and serotonergic effects. Figure created in BioRender.com.

Quadratic forms and Clifford algebras on derived stacks [PDF]

arXiv, 2013
In this paper we present an approach to quadratic structures in derived algebraic geometry. We define derived n-shifted quadratic complexes, over derived affine stacks and over general derived stacks, and give several examples of those. We define the associated notion of derived Clifford algebra, in all these contexts, and compare it with its classical

Brain-derived neurotrophic factor modulation in response to oxidative stress and corticosterone: role of scopolamine and mirtazapine

Life Sciences
Major Depressive Disorder (MDD) is a very complex disease, challenging to study and manage. The complexities of MDD require extensive research of its mechanisms to develop more effective therapeutic approaches. Crucial in the context of this disease is the role of brain-derived neurotrophic factor (BDNF) signaling pathway.This manuscript aims to ...

Local and 2-local derivations of solvable Leibniz algebras [PDF]

arXiv, 2019
We show that any local derivation on the solvable Leibniz algebras with model or abelian nilradicals, whose the dimension of complementary space is maximal is a derivation. We show that solvable Leibniz algebras with abelian nilradicals, which have 1-dimension complementary space, admit local derivations which are not derivations.

Neuroprotection and Enhanced Learning and Memory Abilities of Steamed American Ginseng (Panax quinquefolium L.) Based on Zebrafish

Food Science &Nutrition, Volume 13, Issue 6, June 2025.
Our research is the first to explore the neuroprotective effects of total saponin active compounds isolated from Panax quinquefolius after steaming different times, and to screen out those total saponins with better neuroprotective activity, as well as to conduct a preliminary study on their potential to improve learning and memory impairments.

Derivations of Orthosymplectic Lie Superalgebras [PDF]

arXiv, 2002
In this paper we describe the derivations of orthosymplectic Lie superalgebras over a superring. In particular, we derive sufficient conditions under which the derivations can be expressed as a semidirect product of inner and outer derivations. We then present some examples for which these conditions hold.

Oral morphine used to control intensive pain in a dog (canis familiaris) with tonsil carcinoma, and metastasis in medial retropharyngeal lymph node

Veterinary Record Case Reports, Volume 13, Issue 2, June 2025.
Abstract An 11‐year‐old, female West Highland white terrier presenting cough, emesis, diarrhoea and hyporexia refractory to symptomatic treatment was subjected to endoscopy showing increased palatine tonsil region. Biopsy findings revealed a carcinoma. Computed tomography also showed an increased right medial retropharyngeal lymph node dorsally related

Jordan Derivations and Lie derivations on Path Algebras [PDF]

arXiv, 2012
Without the faithful assumption, we prove that every Jordan derivation on a class of path algebras of quivers without oriented cycles is a derivation and that every Lie derivation on such kinds of algebras is of the standard form.
