The Renormalization Group Evolution of the CKM Matrix [PDF]

open access: yes, 1999
We compute the renormalization of the complete CKM matrix in the MSbar scheme and perform a renormalization group analysis of the CKM parameters. The calculation is simplified by studying only the Higgs sector, which for the \beta-function of the CKM ...

Fluorescence Properties and Mg2+ Selectivity of Aryl‐Alkynyl Derivatives of the o‐Aminophenoltriacetate (APTRA) Ligand

open access: yesChemistry – A European Journal, EarlyView.
It is a challenge to improve the selectivity of high‐denticity ligands for Mg2+ over Ca2+. We show that in aryl‐alkynyl derivatives of APTRA, electron‐withdrawing substituents lower the binding affinity for Ca2+ more than Mg2+, making the ligand more selective for Mg2+.

Compensation for Real Properties Acquired for Roads in Different Procedures - Comparative Analysis

open access: yesReal Estate Management and Valuation, 2017
Real properties acquired for the so-called public purpose, such as road investments, generate a one-off financial indemnity in the form of compensation paid to the expropriated owner.

Measurement of hard double-parton interactions with the ATLAS detector

open access: yes, 2013
The production of W boson in association with two jets in proton-proton collisions at the LHC with a centre-of-mass energy of $\sqrt{s}$ = 7 TeV has been investigated using data collected with the ATLAS detector.

Simple Access to a Series of Higher Substituted Pentafluoroorthotellurate‐Based Silanes

open access: yesChemistry – A European Journal, EarlyView.
The pentafluoroorthotellurate ligand was introduced to organo silanes. A variety of silanes with the formular RxSi(OTeF5)4–x were synthesized and characterized via spectroscopic techniques and sc‐XRD. The influence of the number of OTeF5 groups on structural properties as well as the fluoride ion affinities (FIA) has been studied and compared to other ...

Anti-cancer activity of synthetic gefitinib-1,2,3-triazole derivatives against Hela cells via induction of apoptosis

open access: yesFrontiers in Chemistry
Cervical cancer ranks as the fourth most common cancer among women. However, the current treatments have significant side effects and limited therapeutic effects on advanced diseases, so it is necessary to discover better treatments for cervical cancer ...

Necessary and Sufficient Elastic Stability Conditions in Various Crystal Systems

open access: yes, 2014
While the Born elastic stability criteria are well-known for cubic crystals, there is some confusion in the literature about the form it should take for lower symmetry crystal classes.

Increased HOX C13 expression in metastatic melanoma progression

open access: yesJournal of Translational Medicine, 2012
The process of malignant transformation, progression and metastasis of melanoma is not completely understood. Recently, the microarray technology has been used to survey transcriptional differences that might provide insight into the metastatic process ...

Strong Implications From Small Deviations in Labeling Patterns: The Mechanism of Burkholderia gladioli Pacifigorgiadiene Synthase

open access: yesChemistry – A European Journal, EarlyView.
The mechanism of pacifigorgiadiene synthase from Burkholderia gladioli was investigated through isotopic labeling experiments and DFT calculations. The results revealed an unexpected labeling pattern which appeared to be different in the main and the side products, requiring unprecedented mechanistic explanations, including a “break‐flip‐cyclise ...

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of
