Gamow-Teller strength distributions in Fe and Ni stable isotopes [PDF]

, 2003
We study Gamow-Teller strength distributions in some selected nuclei of particular Astrophysical interest within the iron mass region. The theoretical framework is based on a proton-neutron Quasiparticle Random Phase Approximation built on a deformed ...

The Preparation of Carbon and Nitrogen Stable Isotopes Reference Materials Using Sediments from the Bohai and East China Seas

Yankuang ceshi, 2017
The stable isotope of carbon and nitrogen (δ13C and δ15N) in marine sediments have received much attention as they can be used to trace the sources of organic matter and are helpful in understanding the carbon cycle, climate change and the transformation

Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]

, 2008
Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Fission barriers and asymmetric ground states in the relativistic mean field theory [PDF]

, 1996
The symmetric and asymmetric fission path for 240Pu, 232Th, and 226Ra is investigated within the relativistic mean field model. Standard parametrizations which are well fitted to nuclear ground state properties are found to deliver reasonable qualitative

Dataset of stable isotopes of precipitation in the Eurasian continent [PDF]

Earth System Science Data
Stable isotopes in precipitation can effectively reveal the process of atmospheric water circulation, serving as an effective tool for hydrological and water resource research, climate change, and ecosystem studies. The scarcity of stable isotope data in

Deformation of C isotopes

, 2004
Systematic analysis of the deformations of proton and neutron densities in even-even C isotopes was done based on the method of antisymmetrized molecular dynamics. The $E2$ transition strength was discussed in relation to the deformation. We analyze the $

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Substitution of stable isotopes in Chlorella [PDF]

, 1969
Replacement of biologically important isotopes in the alga Chlorella by corresponding heavier stable isotopes produces increasingly greater deviations from the normal cell size and changes the quality and distribution of certain cellular components.
