We provide an overview of a pressure cell designed to apply uniaxial pressure to single crystals for the study, by neutron scattering techniques, of strongly correlated magnetic systems and, in particular, quantum magnets. A detailed overview of the pressure cell components, their requirements, and links to the scientific and technical specifications are presented. The pressure cell is able to accommodate a 200 mm3 single crystal that can be pressurized up to 2 GPa at cryogenic temperatures. The pressure cell is consistent with the requirements of inelastic neutron scattering and, importantly, neutron polarization analysis. A particular strength of the uniaxial pressure cell is the highly uniform and low background for a wide scattering angle of 360° horizontally and ±20° vertically. We show the performance of the uniaxial pressure cell using a relevant neutron scattering instrument, the polarized diffuse scattering instrument, D7. The experiments confirm that the cell complies with the scientific and technical requirements. This uniaxial pressure cell will provide a useful additional tool in the sample environment suite available for the study of quantum magnetism.

Traumatic brain injury (TBI) remains one of the leading causes of death. Because of the individual nature of the trauma (brain, circumstances and forces), humans experience individual TBIs. This makes it difficult to generalise therapies.

The origin of domestic sheep (Ovis aries) can be traced back to the Asian mouflon (Ovis gmelini), in the Near East around 10 000 years ago. Genetic divergence within mouflon populations can occur due to factors such as geographical isolation, social structures, and environmental pressures, leading to different affinities with domestic sheep. However, few studies have reported the extent to which mouflon sheep contribute to domestic sheep in different regions.

Unlabelled: Tuberculosis (TB) can affect any organ, and at times more than one organ in any sequence, in which case it is referred to as disseminated tuberculosis (DTB). We report a patient who presented primarily for psychiatric symptoms of three months' duration, which later turned out to be a case of DTB involving the central nervous system as well as the spine and lungs.
Case Presentation: An elderly lady with subacute onset and worsening behavioural changes of three months' duration was referred for exclusion of organic brain disease.

Hearing loss is highly related to acoustic injuries and mechanical damage of ear tissues. The mechanical responses of ear tissues are difficult to measure experimentally, especially cochlear hair cells within the organ of Corti (OC) at microscale. Finite element (FE) modeling has become an important tool for simulating acoustic wave transmission and studying cochlear mechanics.
