Deciphering the Interplay Between G‐Quadruplexes and Natural/Synthetic Polyamines

ChemBioChem, Volume 26, Issue 7, April 1, 2025.
The interplay between polyamines and G‐quadruplexes has been largely overlooked in the literature, even though PAs are ubiquitous metabolites in living cells and G4s are transient regulatory elements. Herein, we compile the investigations connecting G4s and biogenic polyamines or synthetic G4 ligands containing polyamines.

Metallographic Spheroidization Rate Classification by Using Deep Learning

Engineering Reports, Volume 7, Issue 4, April 2025.
ABSTRACT In the steel manufacturing process, spheroidizing annealing is a crucial heat treatment step primarily aimed at improving the ductility and machinability of the material. Currently, the determination of the spheroidization rate in metals mainly relies on manual inspection through a microscope.

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

, 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 ...

Strong Rayleigh Wave Radiation Toward Southwest From Ionospheric Observations of the Elbistan Earthquake of the 2023 Kahramanmaras, Türkiye, Doublet

Geophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract The 2023 Elbistan (Mw 7.6) earthquake, the second event of the Kahramanmaraş, Türkiye doublet, occurred by bilateral sub‐ and supershear fault ruptures toward northeast and southwest, respectively. Utilizing the data from a dense network of global navigation satellite system (GNSS) receivers in Türkiye, we investigated the Rayleigh surface ...

Analysis of Observables in Chern-Simons Perturbation Theory

, 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 ...

Nonperturbative Approach to Circuit Quantum Electrodynamics

, 2012
We outline a rigorous method which can be used to solve the many-body Schroedinger equation for a Coulomb interacting electronic system in an external classical magnetic field as well as a quantized electromagnetic field.
