The $\alpha$, $\beta$ and $\gamma$ parameterizations of CP violating CKM phase

, 2012
The CKM matrix describing quark mixing with three generations can be parameterized by three mixing angles and one CP violating phase. In most of the parameterizations, the CP violating phase chosen is not a directly measurable quantity and is ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Power of ‘Nekomimi’: animal-like anthropomorphic agents in environmental education

Cogent Education
The use of virtual teachers (VTs) in environmental education is an important but little-studied issue. The advantage of VTs over robot teachers is that they have more freedom in designing their appearance and can change it immediately.

Turkish Republic of Northern Cyprus Vessel Traffic Services (TRNCVTS) [PDF]

Journal of Eta Maritime Science, 2016
The first Vessel Traffic Service (VTS) started in 1949 in the Liverpool Port (UK) and it continued in Netherlands in 1956. In Turkey, planning and management of the marine traffic using the waterways and ports in Turkey started with Turkish Straits VTS ...

Is Vtb=1 ?

, 2006
The strongest constraint on Vtb presently comes from the 3 x 3 unitarity of the CKM matrix, which fixes Vtb to be very close to one. If the unitarity is relaxed, current information from top production at Tevatron still leaves open the possibility that ...

Unitarity Triangles and the Search for New Physics [PDF]

, 2002
Assuming that the Kobayashi-Maskawa mechanism gives the dominant contribution to CP violation at low energies, we propose a novel way of testing the flavour sector of the Standard Model which has the potencial for discovering New Physics.

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

FEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

RR interval variability in the evaluation of ventricular tachycardia and effects of implantable cardioverter defibrillator therapy

Journal of Arrhythmia, 2021
Background An implantable cardioverter defibrillator (ICD) is the most reliable therapeutic device for preventing sudden cardiac death in patients with sustained ventricular tachycardia (VT).

Implications of the Top Quark Mass Measurement for the CKM Parameters, $x_s$ and CP Asymmetries [PDF]

, 1994
Motivated by the recent determination of the top quark mass by the CDF collaboration, $\mt =174 \pm 10 ^{+13}_{-12}$ GeV, we review and update the constraints on the parameters of the quark flavour mixing matrix $V_{CKM}$ in the standard model.
