Ready to stop: Socioeconomic status and the fertility transition in Stockholm, 1878-1926

The western fertility decline is arguably the most significant demographic change to have occurred in the past 200 years, yet its causes and processes are still shrouded in ambiguity due to a lack of individual-level longitudinal data. A growing body of research has helped improve our understanding of the decline's causes by examining the development of socioeconomic differences in fertility using

Near-Ultraviolet Observations of HD 221170: New Insights into the Nature of r-Process-rich Stars

Employing high-resolution spectra obtained with the near-UV-sensitive detector on the Keck I HIRES, supplemented by data obtained with the McDonald Observatory 2d-coudé, we have performed a comprehensive chemical composition analysis of the bright r-process-rich metal-poor red giant star HD 221170. Analysis of 57 individual neutral and ionized species yielded abundances for a total of 46 elements

The importance of CTLA-4 polymorphism and human leukocyte antigen genotype for the induction of diabetes-associated cytokine response in healthy school children.

Type 1 diabetes (T1D) is an autoimmune disease associated with the destruction of pancreatic β cells and genetically linked to human leukocyte antigen (HLA) class II DR3-DQ2 and DR4-DQ8 haplotypes. The +49A/G polymorphism of the immunoregulatory cytotoxic T-lymphocyte antigen 4 (CTLA-4) gene is also associated with T1D. Genetic and environmental risk factors precede the onset of T1D, which is char
