In the management of reservoirs, different forms of infrastructure (such as dams, hydropower units, information) are functionally interdependent and often managed by different types of actors to form a social-ecological-technological system. Such interdependence also occurs because institutions (understood as rules that guide and constrain actor behavior) exist to indicate how infrastructures should be managed. We apply institutional analysis and social network analysis to identify how functionally interdependent infrastructures and actors are connected by formal rules created to manage reservoir operations in Argentina (Ameghino Dam, Chubut) and the United States (Coyote Valley Dam, California).

Nuclear DNA is organized into a compact three-dimensional (3D) structure that impacts critical cellular processes. High-throughput chromosome conformation capture (Hi-C) is the most widely used method for measuring 3D genome architecture, while linear epigenomic assays, such as ATAC-seq, DNase-seq, and ChIP-seq, are extensively employed to characterize epigenomic regulation. However, the integrative analysis of chromatin interactions and associated epigenomic regulation remains challenging due to the pairwise nature of Hi-C data, mismatched resolution between Hi-C and epigenomic assays, and inconsistencies among analysis tools.

Consistent evidence shows that women are underrepresented across most Science, Technology, Engineering, and Mathematics fields. Research indicates that early attitudes and gendered beliefs about mathematics can predict later achievement and academic choices in Science, Technology, Engineering, and Mathematics and that children's attitudes are tied to parents' beliefs and interactions with their children surrounding math. To identify potential antecedents of gender differences, we examined whether there are differences between parents of sons and parents of daughters on factors in the home mathematics environment that influence early math experiences for young children.

January 2025

State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation, Chengdu University of Technology, Chengdu, China.

The boundary between wet and arid climate zones in the Tethys Ocean remains challenging to trace, complicating our understanding of global aridification pattern during the Late Carboniferous to Early Permian transition. The North China Block (NCB), situated in the Tethys Ocean, underwent a transition from humid to arid climate during the Early Permian, providing a rare opportunity to trace this climate boundary across this region. Here, we present paleomagnetic evidence indicating that the NCB underwent rapid northward drift between 290 and 281 million years ago.
