Analysis of a reaction-diffusion system of ƛ -w type [PDF]
, 2003 The author studies two coupled reaction-diffusion equations of 'ƛ - w' type, on an open, bounded, convex domain Ω C R(^d) (d ≤ 3), with a boundary of class C(^2), and homogeneous Neumann boundary conditions.

Four-body extension of the continuum-discretized coupled-channels method [PDF]
, 2018 I develop an extension of the continuum-discretized coupled-channels (CDCC) method to reactions where both nuclei present a low breakup threshold. This leads to a four-body model, where the only inputs are the interactions describing the colliding nuclei,

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Reactions with Exotic Nuclei at Near and Sub-barrier Energies [PDF]
EPJ Web of Conferences, 2019 We will introduce some new results derived recently by the nuclear reaction group at China Institute of Atomic Energy, on the properties of the optical model potentials of neutron-halo 6He system and reaction mechanisms induced by proton-drip line ...

Cluster scattering in the non-local model
Frontiers in Physics, 2023 Scattering of weakly bound nuclei with a pronounced cluster structure is strongly affected by their breakup. Usually, this mechanism is accounted for in a three-body model with pairwise potentials.

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

7Li(18O, 17O)7Li reaction and the 17N + 8Be-potential [PDF]
Ядерна фізика та енергетика, 2011 The new data of the angular distributions of 7Li(18O, 16N)9Be reaction were obtained for the transitions to the ground and excited states of 8Be and 17N at the energy Elab(18O) = 114 MeV.

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 ...

Elastic and inelastic scattering of 15n ions by 11B at 84 MeV [PDF]
Ядерна фізика та енергетика, 2014 Angular distributions of the 11B + 15N elastic and inelastic scattering were measured at Elab (15N) = 84 MeV. The data were analyzed within the optical model and coupled-reaction-channels method.

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.
