Energy as witness of multipartite entanglement in spin clusters

open access: yes, 2012
We derive energy minima for biseparable states in three- and four-spin systems, with Heisenberg Hamiltonian and s

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

4,4′,6,6′-Tetra-tert-butyl-2,2′-[1,2-phenylenebis(nitrilomethylidyne)]diphenol acetone solvate

open access: yesActa Crystallographica Section E, 2008
In the Schiff base molecule of the title compound, C36H48N2O2·C3H6O, the central benzene ring makes dihedral angles of 46.64 (10) and 49.34 (10)° with the two outer benzene rings, and the two outer benzene rings form an angle of 39 ...

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

open access: yesMolecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

On the enumeration of symmetric tridiagonal matrices with prescribed determinant over commutative finite chain rings

open access: yesSpecial Matrices
Determinants of structured matrices play a fundamental role in both pure and applied mathematics, with wide-ranging applications in linear algebra, combinatorics, coding theory, and numerical analysis.

(7R,8S,9S,12S)-1-Benzyloxy-13,14-didehydro-12-hydroxy-2,13-dimethoxy-N-methylmorphinane

open access: yesActa Crystallographica Section E, 2011
In the title compound, C26H31NO4, a sinomenine derivative, the angle between the two aromatic rings is 53.34 (4)°. The N-containing ring is in a chair conformation, while the other two non-planar rings are in a half-boat conformation ...

1-Decyl-6-nitro-1H-benzimidazol-2(3H)-on [PDF]

open access: yes, 2011
The title mol­ecule, C17H25N3O3, is built up from fused six- and five-membered rings linked to a –C10H21 chain. The fused-ring system is essentially planar, the largest deviation from the mean plane being 0.009 (2) Å.

Lattice of ideals of the polynomial ring over a commutative chain ring [PDF]

open access: yesApplicable Algebra in Engineering, Communication and Computing, 2015
Let $R$ be a commutative chain ring. We use a variation of Gröbner bases to study the lattice of ideals of $R[x]$. Let $I$ be a proper ideal of $R[x]$. We are interested in the following two questions: When is $R[x]/I$ Frobenius? When is $R[x]/I$ Frobenius and local? We develop algorithms for answering both questions. When the nilpotency of $\text{rad}\

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

An amphiphilic pseudo[1]catenane: neutral guest-induced clouding point change

open access: yesBeilstein Journal of Organic Chemistry, 2018
The hydrophobic/hydrophilic ratio in a molecule largely affects its assembled properties in aqueous media. In this study, we synthesized a new bicyclic compound which could dynamically change its hydrophobic/hydrophilic ratio by chemical stimulus.
