Model Theory and Complexity Theory
This presentation explores the intersection of finite model theory and complexity theory, with a focus on descriptive complexity—a framework that classifies computational problems based on the logical languages needed to express them. It highlights classical results such as Fagin’s theorem (NP = Σ₁¹) and Immerman’s characterization of P, and introduces

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

On λ strong homogeneity existence for cofinality logic
Cubo, 2011 Let C Reg be a non-empty class (of regular cardinals). Then the logic has additional nice properties: it has the homogeneous model existence property.Sea C Reg una clase no vacía (de cardinales regulares). Entonces la lógica tiene propiedades adicionales:

Multilevel Ventilation: Theory and Simplified Mathematical Model
Общая реаниматология, 2008 Considering the issues of artificial ventilation (AV) in non-homogenous pathological lung processes (acute lung injury, acute respiratory distress syndrome, pneumonia, etc.), the authors created a mathematical model of multicompartment non-homogenous ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.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 ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Supersymmetric SYK model and random matrix theory
Journal of High Energy Physics, 2017 In this paper, we investigate the effect of supersymmetry on the symmetry classification of random matrix theory ensembles. We mainly consider the random matrix behaviors in the N = 1 $$ \mathcal{N}=1 $$ supersymmetric generalization of Sachdev-Ye-Kitaev

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