Mitochondrial Donation: The UK Experience
Fertility & Reproduction, 2023 Mutations in mitochondrial DNA (mtDNA) are inherited exclusively from our mothers and can cause a broad range of debilitating and fatal diseases. Reproductive technologies designed to uncouple the inheritance of the mitochondrial genome from the nuclear ...

Determination of photo-nuclear cross section of $^{61}$Ni($γ$,xp) reaction via surrogate ratio technique [PDF]
arXiv, 2022 The photo nuclear reaction cross section of $^{61}$Ni($\gamma$,xp) reaction have been measured by employing surrogate reaction technique. This indirect method is used for the first time to obtain the cross section of photo nuclear reaction. The compound nucleus $^{61}$Ni$^{*}$ was populated using the transfer reaction $^{59}$Co($^{6}$Li,$\alpha$) at E ...

Extraction of two-photon contributions to the proton form factors [PDF]
Phys.Rev. C71 (2005) 015202, 2004 Significant discrepancies have been observed between proton form factors as measured by Rosenbluth separation and polarization transfer techniques. There are indications that this difference may be caused by corrections to the one photon exchange approximation that are not taken into account in standard radiative correction procedures.

Microscopic description of pair transfer between two superfluid Fermi systems: combining phase-space averaging and combinatorial techniques [PDF]
Phys. Rev. C 97, 034627 (2018), 2017 In a mean-field description of superfluidity, particle number and gauge angle are treated as quasi-classical conjugated variables. This level of description was recently used to describe nuclear reactions around the Coulomb barrier. Important effects of the relative gauge angle between two identical superfluid nuclei (symmetric collisions) on transfer ...

Magnetochemistry, 2018 The 19F{1H} saturation transfer difference (STD) method was improved for sensitive 19F detection using a human serum albumin-diflunisal complex. Because NMR (nuclear magnetic resonance) experiments with 19F detection are feasible for the selective ...

Preparation of Nuclear Spin Singlet States using Spin-Lock Induced Crossing [PDF]
Phys. Rev. Lett. 111, 173002 (2013), 2013 We introduce a broadly applicable technique to create nuclear spin singlet states in organic molecules and other many-atom systems. We employ a novel pulse sequence to produce a spin-lock induced crossing (SLIC) of the spin singlet and triplet energy levels, which enables triplet/singlet polarization transfer and singlet state preparation.

Investigating Globular Cluster Elemental Abundance Anomalies Using $(^3\text{He},d)$ Proton Transfer Reactions [PDF]
arXiv, 2021 Globular clusters are dense aggregates of stars that evolve in relative isolation. For the better part of $40$ years these clusters have been known to possess unique chemical signatures called abundance anomalies. Recent observations have found these abundance anomalies to be the result of distinct stellar populations with the youngest population ...
