Minor actinide fission induced by multi-nucleon transfer reaction in inverse kinematics

open access: yesEPJ Web of Conferences, 2010
In the framework of nuclear waste incineration and design of new generation nuclear reactors, experimental data on fission probabilities and on fission fragment yields of minor actinides are crucial to design prototypes.

Study of effective interaction from single particle transfer reactions on f-p shell nuclei

open access: yes, 1999
The present study concentrates on the average effective two-body interaction matrix elements being extracted, using sum-rule techniques, from transfer reactions on target states having single orbital as well as two orbitaloccupancy.

Comparison of Umbilical Cord Mesenchymal Stem Cells and Fibroblasts as Donor Nuclei for Handmade Cloning in Sheep Using a Single-Cell Transcriptome

open access: yesAnimals
Oocytes are efficient at reprogramming terminally differentiated cells to a totipotent state. Nuclear transfer techniques can exploit this property to produce cloned animals. However, the overall efficiency is low.

Technical Challenges in the Derivation of Human Pluripotent Cells

open access: yesStem Cells International, 2011
It has long been discovered that human pluripotent cells could be isolated from the blastocyst state of embryos and called human embryonic stem cells (ESCs). These cells can be adapted and propagated indefinitely in culture in an undifferentiated manner

Neutral-Current Atmospheric Neutrino Flux Measurement Using Neutrino-Proton Elastic Scattering in Super-Kamiokande [PDF]

open access: yes, 2003
Recent results show that atmospheric $\nu_\mu$ oscillate with $\delta m^2 \simeq 3 \times 10^{-3}$ eV$^2$ and $\sin^2{2\theta_{atm}} \simeq 1$, and that conversion into $\nu_e$ is strongly disfavored.

A Review of the Uses of Nuclear Radiation in Tobacco and Smoke Research

open access: yesContributions to Tobacco and Nicotine Research, 1990
In summary, nuclear radiation has been widely used to elucidate many aspects of the mechanisms of tobacco being converted to smoke. In addition, the mechanisms of smoke transfer, tobacco inorganic chemistry and smoke filtration have been clarified by ...

Mitochondrial transfer: Ethical legal and social implications in assisted reproduction

open access: yesSouth African Journal of Bioethics and Law, 2015
Diseases resulting from mutations in mitochondrial DNA (mtDNA) are inherited by all offspring through the maternal lineage. Multiple organs, which require high cellular energy production, are severely affected.

Synthesis, characterization and evaluation of transfection efficiency of dexamethasone conjugated poly(propyleneimine) nanocarriers for gene delivery#

open access: yesPharmaceutical Biology, 2018
Context: Polypropylenimine (PPI), a cationic dendrimer with defined structure and positive surface charge, is a potent non-viral vector. Dexamethasone (Dexa) conveys to the nucleus through interaction with its intracellular receptor.

Quantum entanglement and spin control in silicon nanocrystal [PDF]

open access: yes, 2012
Selective coherence control and electrically mediated exchange coupling of single electron spin between triplet and singlet states using numerically derived optimal control of proton pulses is demonstrated.

Quantitative CEST imaging of amide proton transfer in acute ischaemic stroke

open access: yesNeuroImage: Clinical, 2019
Background: Amide proton transfer (APT) imaging may help identify the ischaemic penumbra in stroke patients, the classical definition of which is a region of tissue around the ischaemic core that is hypoperfused and metabolically stressed.
