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.

Multipliers of Sequence Spaces
Rocky Mountain Journal of Mathematics, 1993 Let \(A = (a_{nk})\) be a triangular nonnegative regular summability matrix. Denote by \(m_ A\) the linear space of sequences \(\{s_ n\}\) such that the \(A\)-transform is bounded. Let \((c_ 0)_ A\) be the closed subspace of sequences \(\{t_ n\}\) which are evaluated to 0 by \(A\). Denote by \(m_ A\) the Banach space \(\widetilde m_ A/(c_ 0)_ A\).

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Pre main sequence stars as UV sources for the World Space Observatory-UV mission
, 2011 Pre-main sequence stars are bright UV (UV) sources compared with their main sequence analogues. The source of this excess is the high energy processes associated with the physics of accretion/outflow during early stellar evolution.

The Hahn Sequence Space Defined by the Cesaro Mean
, 2021 The BK-space of all sequences is given as x = (x(k)) such that Sigma(infinity)(k=1)k vertical bar x(k) - x(k+1)vertical bar converges and x(k) is a null sequence which is called the Hahn sequence space and is denoted by h. Hahn (1922) defined the h space

Attenuation of RNA viruses by redirecting their evolution in sequence space
Nature Microbiology, 2017 RNA viruses pose serious threats to human health. Their success relies on their capacity to generate genetic variability and, consequently, on their adaptive potential.

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Norms of certain operators on weighted L-spaces and Lorentz sequence spaces. [PDF]
, 2002 The problem addressed is the exact determination of the norms of the classical Hilbert, Copson and averaging operators on weighted spaces and the corresponding Lorentz sequence spaces , with the power weighting sequence or the variant defined by .

Hausdorff measure of noncompactness of matrix operators on some new difference sequence spaces
Journal of Inequalities and Applications, 2016 The new sequence spaces X ( r , s , t ; Δ ) $X(r,s,t;\Delta)$ for X ∈ { l ∞ , c , c 0 } $X\in\{l_{\infty}, c, c_{0}\}$ have been defined by using generalized means and difference operator.
