Charged Lepton Flavor Violation in a class of Radiative Neutrino Mass Generation Models

open access: yes, 2018
We investigate charged lepton flavor violating processes $\mu\rightarrow e \gamma$, $\mu\rightarrow e e \overline{e}$ and $\mu-e$ conversion in nuclei for a class of three-loop radiative neutrino mass generation models with electroweak multiplets of ...

Ecological speciation with gene flow followed initial large‐scale geographic speciation in the enigmatic afroalpine giant senecios (Dendrosenecio)

open access: yesNew Phytologist, Volume 246, Issue 5, Page 2307-2323, June 2025.
Summary Mountains have highly heterogeneous environments that generate ample opportunities for lineage differentiation through ecological adaptation, geographic isolation and secondary contact. The geographic and ecological isolation of the afroalpine vegetation fragments on the East African mountain tops makes them an excellent system to study ...

Environmentally Stable and Highly Crystalline MXenes for Multispectral Electromagnetic Shielding up to Millimeter Waves

open access: yesAdvanced Functional Materials, Volume 35, Issue 18, May 2, 2025.
This study presents excellent EMI shielding effectiveness of highly crystalline HC‐Ti3C2Tx MXene, characterized by high electrical conductivity, outstanding environmental stability, and facile processability, across a multispectral frequency range from 100 kHz to 110 GHz. It is revealed that increasing the thickness and electrical conductivity of MXene

Methodology of high‐dimensional flow cytometry in monitoring immune microenvironment of pituitary neuroendocrine tumors

open access: yesCytometry Part B: Clinical Cytometry, Volume 108, Issue 3, Page 234-251, May 2025.
Abstract Characterization of the tumor immune microenvironment (TIME) of pituitary neuroendocrine tumors (PitNETs) is crucial for understanding the behavior of different types of PitNETs and identification of possible causes of their aggressiveness, rapid growth, and resistance to therapy.

CP-odd effective gluonic Lagrangian in Kobayashi-Maskawa model

open access: yes, 1994
Schwinger operator method is applied for studying CP-odd pure gluonic effective Lagrangian in the Standard Model at three-loop level. The induced $\theta$-term vanishes by the same reasons as EDMs of quark and W-boson to two-loop approximation.

Explicitly symmetrical treatment of three-body phase space

open access: yes, 2002
We derive expressions for three-body phase space that are explicitly symmetrical in the masses of the three particles. We study geometrical properties of the variables involved in elliptic integrals and demonstrate that it is convenient to use the ...

All orders structure and efficient computation of linearly reducible elliptic Feynman integrals

open access: yes, 2019
We define linearly reducible elliptic Feynman integrals, and we show that they can be algorithmically solved up to arbitrary order of the dimensional regulator in terms of a 1-dimensional integral over a polylogarithmic integrand, which we call the inner

Dark energy, cosmological constant and neutrino mixing

open access: yes, 2007
The today estimated value of dark energy can be achieved by the vacuum condensate induced by neutrino mixing phenomenon. Such a tiny value is recovered for a cut-off of the order of Planck scale and it is linked to the sub eV neutrino mass scale ...
