The evolution and history of Vinca alkaloids: From the Big Bang to the treatment of pediatric acute leukemia

open access: yesPediatric Blood &Cancer, Volume 71, Issue 11, November 2024.
Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...

Improved precision on 2–3 oscillation parameters using the synergy between DUNE and T2HK

open access: yesJournal of High Energy Physics
A high-precision measurement of ∆ m 31 2 $$ \Delta {m}_{31}^2 $$ and θ 23 is inevitable to estimate the Earth’s matter effect in long-baseline experiments which in turn plays an important role in addressing the issue of neutrino mass ordering and to ...

Double Beta Decay and the Absolute Neutrino Mass Scale

open access: yes, 2003
After a short review of the current status of three-neutrino mixing, the implications for the values of neutrino masses are discussed. The bounds on the absolute scale of neutrino masses from Tritium beta-decay and cosmological data are reviewed. Finally,

Smart mechanoluminescent phosphors: A review of zinc sulfide‐based materials for advanced mechano‐optical applications

open access: yesResponsive Materials, Volume 2, Issue 3, August 2024.
Zinc sulfide is a smart luminescent material with exceptionally outstanding mechanoluminescence properties. After over a century of research, it is now widely used in wearable devices, auxiliary lighting, stress sensing, anti‐counterfeiting, and other fields.

Theory of neutrino fast flavor evolution. Part I. Linear response theory and stability conditions.

open access: yesJournal of High Energy Physics
Neutrino-neutrino refraction leads to collective flavor evolution that can include fast flavor conversion, an ingredient still missing in numerical simulations of core-collapse supernovae.

Flavour-symmetric type-II Dirac neutrino seesaw mechanism

open access: yesPhysics Letters B, 2018
We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the “golden” flavour-dependent bottom-tau mass relation, requires an inverted neutrino ...

The SO(10)-inspired leptogenesis timely opportunity

open access: yesJournal of High Energy Physics, 2020
We study the connection between absolute neutrino mass and neutrino mixing parameters within SO(10)-inspired leptogenesis. We show that current favoured values of the unknown neutrino mixing parameters point toward values of the absolute neutrino mass ...

Reproducing lepton mixing in a texture zero model

open access: yes, 2013
We note that the emerging features of lepton mixing can be reproduced if, with inverted neutrino mass ordering, both the smallest neutrino mass and the $\tau\tau$ element of the neutrino mass matrix vanish.

Solar neutrinos and neutrino mixing

open access: yesPhysics Letters B, 1976
Abstract The recent suggestion that mixing of many neutrino types accounts for the solar neutrino puzzle is discussed. We find that in general the suppression due to mixing of k species is by less than a factor k.

Neutrino masses and flavor mixing [PDF]

open access: yesModern Physics Letters A, 2010
We discuss the neutrino oscillations, using texture zero mass matrices for the leptons. The reactor mixing angle θl is calculated. The ratio of the masses of two neutrinos is determined by the solar mixing angle. We can calculate the masses of the three neutrinos: m1 ≈ 0.003 eV , m2 ≈ 0.012 eV , m3 ≈ 0.048 eV .
