I am Me: Brain systems integrate and segregate to establish a multidimensional sense of self
NeuroImage, 2020 Humans experience a sense of self, which is proposed to emerge from the integration of intrinsic and extrinsic self-processing through the propagation of information across brain systems.

On certain identities in theta functions [PDF]
Transactions of the American Mathematical Society, 1930 1. The purpose of this paper is to obtain certain identities in Jacobi's theta functions by a new method. This method may be outlined as follows. We consider two sets of elements S and Si, conceptually distinct, such that the elements of S are in one-to-one correspondence with the elements of S1.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

A unimodality identity for a Schur function
Journal 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
FEBS 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.

A Proof of an Identity for Multiplicative Functions [PDF]
Canadian 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
FEBS 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.

An Integral Identity for the Rademacher Functions
Journal of Mathematical Analysis and Applications, 1995 Denote by \(r_j(t)\) the well-known Rademacher functions with the kernel \[ K_n(s, t):= \sum^n_{j= 1} r_j(s) r_j(t),\quad 0\leq s, t\leq 1\quad\text{and}\quad n= 1, 2,\dots\;. \] The author proves the identity \[ \int^1_0 r_{j_1}(s)\cdots r_{j_m}(s)\;F(K_n(s, t)) ds= C^{m, n}_F r_{j_1}(t)\cdots r_{j_m}(t), \] where \(0\leq m\leq n\), \(1\leq ...

The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes
FEBS Letters, EarlyView.Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.
