Non-universal Critical Quantities from Variational Perturbation Theory and Their Application to the BEC Temperature Shift

open access: yes, 2004
For an O(N) symmetric scalar field theory with Euclidean action integral d^3x [1/2 |nabla phi|^2 + 1/2 r phi^2 + 1/4! u phi^4], where phi = (phi_1,...,phi_N) is a vector of N real field components, variational perturbation theory through seven loops is ...

Analysis of Observables in Chern-Simons Perturbation Theory

open access: yes, 1991
Chern-Simons Theory with gauge group $SU(N)$ is analyzed from a perturbation theory point of view. The vacuum expectation value of the unknot is computed up to order $g^6$ and it is shown that agreement with the exact result by Witten implies no quantum ...

Exploring the Modulation of the Complex Folding Landscape of Human Telomeric DNA by a Low Molecular Weight Ligand

open access: yesChemistry – A European Journal, Volume 31, Issue 32, June 6, 2025.
Time‐resolved nuclear magnetic resonance (NMR) and circular dichroism (CD) spectroscopy were utilized to investigate the complex G‐quadruplex folding landscape of the human telomeric DNA in the presence of the ligand Phen‐DC3. Our findings revealed significant differences in the kinetics of the pathways originating from the unfolded or K+‐bound state ...

Genetic diversity among black cumin (Nigella sativa L.) accessions based on quantitative and qualitative traits

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract To investigate the genetic diversity in black cumin (Nigella sativa L.), a total of 64 genotypes were tested in an 8 × 8 simple lattice design at Sirinika Agricultural Research Center for two consecutive years during 2022/2023 and 2023/2024.

Effects of Melatonin on Exercise-Induced Oxidative Stress in Adults with Obesity Undergoing a Multidisciplinary Body Weight Reduction Program. [PDF]

open access: yesJ Clin Med
Background: Obesity is characterized by increased oxidative stress, which, in a vicious circle, promotes chronic low-grade inflammation. Melatonin, a well-documented antioxidant, might be useful as a supplement to enhance the cardiometabolic benefits of ...

Multi‐environmental trial and stability study of Ethiopian sesame (Sesamum indicum L.) genotypes at Western Oromia

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Sesame (Sesamum indicum L.) is the most important oil crop in the world. A multi‐environmental yield trial is used to assess genotype‐by‐environment interaction for selecting superior genotypes. The current study was initiated to identify stable and high‐yielding sesame genotypes. Accordingly, 16 sesame genotypes were evaluated in a randomized
