Low-energy dipole modes in the heavy deformed nucleus 154Sm via inelastic polarized proton scattering at 0°

EPJ Web of Conferences, 2012
A high resolution proton scattering experiment has been performed on the heavy deformed nucleus 154Sm at extreme forward angles with 300 MeV polarized protons at RCNP, Osaka. Our scientific goal is to investigate the impact of ground state deformation on

Overview of Spin Physics at EIC [PDF]

, 2018
The possibilities to measure spin effects at a high-energy Electron-Ion Collider (EIC) are reviewed from a theory point of view. Various types of spin distributions and promising observables are discussed.Comment: 9 pages; based on an invited talk at the

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Kaon Photoproduction: From an Experimental Point of View

Makara Journal of Science, 2017
Today, laboratory experiments conducted worldwide continue to search for undiscovered excited states of the nucleon. The database has been continually updated over the past years to allow for nearly model-independent partial wave analyses (PWA) to be ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Pion Exchange Effects in Elastic Backward Proton-Deuteron Scattering [PDF]

, 1998
The elastic backward proton-deuteron scattering is analyzed within a covariant approach based on the Bethe-Salpeter equation with realistic meson-exchange interaction. Contributions of the one-nucleon and one-pion exchange mechanisms to the cross section

Neutron–Proton Scattering Experiments at ANKE–COSY

EPJ Web of Conferences, 2010
The nucleon–nucleon interaction (NN) is fundamental for the whole of nuclear physics and hence to the composition of matter as we know it. It has been demonstrated that stored, polarised beams and polarised internal targets are experimental tools of ...

Photoproduction of π0-Mesons from the Nucleon and Deuteron

Makara Journal of Science, 2016
The photoproduction of π0-mesons from the nucleon and deuteron has been studied for incidents of photon energies up to 1.5 GeV. By using the MAID-2007 model for the process on the nucleon, we predict results for the unpolarized and helicity-dependent ...

Holonomy observables in Ponzano-Regge type state sum models [PDF]

, 2011
We study observables on group elements in the Ponzano-Regge model. We show that these observables have a natural interpretation in terms of Feynman diagrams on a sphere and contrast them to the well studied observables on the spin labels.
