We investigated decays of ^{51,52,53}K at the ISOLDE Decay Station at CERN in order to understand the mechanism of the β-delayed neutron-emission (βn) process. The experiment quantified neutron and γ-ray emission paths for each precursor. We used this information to test the hypothesis, first formulated by Bohr in 1939, that neutrons in the βn process originate from the structureless "compound nucleus.

- The gyromagnetic factor of an isomeric state in the nucleus ^{99}Zr was measured, showing it has a spin-parity of J^{π}=7/2^{+} and a half-life of 336 ns.
- The isomer was created through the abrasion-fission of a uranium beam at RIKEN RIBF, revealing that its magnetic moment suggests it is not a simple single-particle state.
- Comparisons with theoretical models indicate that this state has strong mixing characteristics and shows significant changes in single-particle evolution when collective modes are present.
The authors describe a rare case of secondary abdominal pregnancy after in vitro fertilization pre-embryo transfer (IVF-ET). Ultrasonography was applied to image ectopic gestational sac containing a yolk vesicle and located adjacent to the anterior uterine wall and left adnexa. Laparoscopy was done on the same day followed by sinistral salpingectomy due to tubal abortion indications.

An in Vitro Fertilization Pre-Embryo Transfer (IVF-ET) procedure was done and presently is known that the patient has left fallopian tube and left ovary, two kidneys, and right ovary is missing. No diagnostic laparoscopy and hysteroscopy were done, only hysterosalpingography (HSG) before the IVF procedure.
