Functional Identities in Superalgebras: Theoretical Insights and Computational Verification

open access: yes
This paper investigates functional identities in superalgebras, building on Wang’s foundational work. We study d-superfree subsets and k-supercommuting maps in prime superalgebras, both with and without superinvolution, introducing new results on ...

To reveal disease or to promote function – that is the question

open access: yesScandinavian Journal of Primary Health Care
Medicine faces challenges that indicate that it may not be sustainable. A descriptive disease concept is apt to what philosopher of science Ian Hacking called "looping effects”, which can explain why health care is faced with insatiable demands. Diseases

A unimodality identity for a Schur function

open access: yesJournal of Combinatorial Theory, Series A, 1992
A new formula for the principal specialization of a Schur function is given. The identity implies that the sequence of coefficients of this polynomial is unimodal. The proof of the main result is based on a combinatorial construction due to \textit{S. V. Kerov}, \textit{A. N. Kirillov} and \textit{N. Yu. Reshetikhin} [J. Sov. Math. 41, No. 2, 916--924 (

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Auxiliary Linear Problem, Difference Fay Identities and Dispersionless Limit of Pfaff-Toda Hierarchy

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Recently the study of Fay-type identities revealed some new features of the DKP hierarchy (also known as ''the coupled KP hierarchy'' and ''the Pfaff lattice'').

A Proof of an Identity for Multiplicative Functions [PDF]

open access: yesCanadian Mathematical Bulletin, 1979
An arithmetic function f is said to be multiplicative if f(mn) = f(m)f(n), whenever (m, n) = 1 and f(1) = 1. The Dirichlet convolution of two arithmetic functions f and g, denoted by f • g, is defined by f • g(n) = Σd|nf(d)g(n/d). Let w(n) denote the product of the distinct prime factors of n, with w(l) = 1. R.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Increased Medial Prefrontal Cortex and Decreased Zygomaticus Activation in Response to Disliked Smiles Suggest Top-Down Inhibition of Facial Mimicry

open access: yesFrontiers in Psychology, 2019
Spontaneous facial mimicry is modulated by many factors, and often needs to be suppressed to comply with social norms. The neural basis for the inhibition of facial mimicry was investigated in a combined functional magnetic resonance imaging and ...
