Detection of rare earth elements and rare earth oxides with hyperspectral spectroscopy
The continuously increasing demand for rare earth elements in technical components of modern technologies, brings the detection of new deposits closer into the focus of global exploration. One promising method to globally map important deposits might be remote sensing, since it has been used for a …

Rare gas alkali ionic excimers
The rare gas alkali ionic molecules are established as a new class of ionic excimers which emit in the vacuum ultraviolet (VUV) regime of the electromagnetic spectrum. Temporal and spectral characteristics of these species with (XeRb)$\sp{+}$ at 164 nm and (XeCs)$\sp{+}$ at 160 nm have been …

Germline mutation in rare disease
… and the contribution of these mutations to rare developmental disorders. These sources of variation encompass types of mutations that have been previously underrepresented in genetic research as well as individual mutation rates and spectra across individuals and parental origin. These …

Rare-event searches with bolometers
Rare-event searches have played an integral part in the pursuit of physics beyond the Standard Model, offering us the chance to bridge the disparity between our current understanding and observed phenomena such as Dark Matter (DM) or the nature of neutrino masses. Over the last 30 years, these …

Lessons from a rare disease
Progeria is a genetic aging disease of childhood affecting an estimated one in four to eight million births. Children with progeria experience a range of developmental disorders and aging-like symptoms, including wrinkled and discolored skin, stunted growth, visible veins, fat loss, hair loss, bone …

On inference about rare events
… are critical precisely because they are rare. We then have to raise the natural question: when can we infer something meaningful in such contexts? The focal point of this thesis is the archetypal problem of estimating the probability of symbols that have occurred very rarely, in samples …

Identifying, understanding, and conserving rare species
… biodiversité à l’échelle mondiale, les espèces rares méritent une attention particulière dans les efforts de conservation, car elles sont plus vulnérables à l'extinc-tion que les espèces communes. À la suite de l'adoption du Cadre mondial pour la biodiversité Kunming-Montréal en 2022, le Canada …

Thermoelectric transport in rare-earth compounds
… on the thermoelectric transport properties of rare-earth compounds containing Ce, Eu, and Yb. These systems have been investigated either to study fundamental problems or to evaluate their potential for thermoelectric applications.

Magnetism in crystalline rare-earth compounds
… largely due to the complex behaviour of rare-earth ions. The technique of choice is diffraction; shown to pro- vide the most lucid of results in this field of research. Neutron powder diffraction, a well established tool for determining magnetic structures, has been employed in order to …

Rare Genetic Variants and Cancer Susceptibility
… identified through GWAS, together with some rarer variants conferring higher disease risks. The latter, identified through genetic linkage or targeted sequencing studies, includes protein-truncating variants and some rare missense variants in ATM, BARD1, BRCA1, BRCA2, CHEK2, RAD51C, RAD51D, …

How Are Rare Species Maintained?: Reproductive Barriers Between Layia jonesii, a Rare Serpentine Endemic, and L. platyglossa
… barriers are maintained, particularly between rare and widespread relatives. <em>Layia jonesii</em>, a rare San Luis Obispo County serpentine endemic, and <em>L. platyglossa, </em>a common coastal species,<em> </em>co-occur on serpentine derived hillsides and are interfertile. At these …
