BERGMANN AND HARDY SPACES AND CONJUGATE OF THEM
It is proved that space is strongly notmed, and is neither strongly notmed, nor uniformly convex. A standard form of the linear functionals over space and over metric spaces of 0 < p £ 1, is determined.

On AdS 2 holography from redux, renormalization group flows and c-functions
Extremal black branes upon compactification in the near horizon throat region are known to give rise to AdS 2 dilaton-gravity-matter theories. Away from the throat region, the background has nontrivial profile.

The extremal function for Petersen minors [PDF]
We prove that every graph with $n$ vertices and at least $5n-8$ edges contains the Petersen graph as a minor, and this bound is best possible. Moreover we characterise all Petersen-minor-free graphs with at least $5n-11$ edges. It follows that every graph containing no Petersen minor is 9-colourable and has vertex arboricity at most 5.

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Extremal Problems for Graphs and Hypergraphs
Given a fixed graph G and a positive integer n, the extremal number [Turan, 1941] denotes the maximum number of edges a graph on n vertices can have without copies of G.

Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Extremal functions for real convex bodies: simplices, strips, and ellipses
We present an explicit method to compute the (Siciak-Zaharjuta) extremal function of a real convex polytope in terms of supporting simplices and strips.

Weakening the nuclear envelope: Lamin B receptor in melanoma metastasis
LBR‐driven nuclear fragility supports melanoma invasion. A: Melanocyte presents low LBR (Lamin B Receptor) levels, maintaining nuclear integrity and lamina‐chromatin tethering. B: During malignant progression, upregulation of LBR clusters at the INM (Inner Nuclear Membrane) during confined migration causes local lamina weakening and cholesterol ...

Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Existence of an extremal function of critical Sobolev embedding with an $\alpha $-homogeneous weight
In [Calc. Var. Partial Differ. Equ. 60 (2021), no. 1, article no. 16 (27 pages)], we revisited a critical Sobolev-type embedding for weighted Sobolev spaces as introduced in [J. Differ. Equations 255 (2013), no. 11, pp.
