Article Synopsis
- Sambaqui societies, existing from 8,000 to 1,000 years ago along the Atlantic coast of South America, represent a unique archaeological phenomenon that is still poorly understood in terms of their origins and evolution.
- Research involving genome-wide data from 34 ancient individuals found that early Holocene hunter-gatherers did not show genetic ties to later populations, indicating minimal contribution to coastal groups.
- The study revealed genetic diversity among different Sambaqui communities, suggesting a more complex history of interaction between inland farmers and coastal societies than what is reflected in the archaeological records.
We show that models of opinion formation and dissemination in a community of individuals can be framed within stochastic thermodynamics from which we can build a nonequilibrium thermodynamics of opinion dynamics. This is accomplished by decomposing the original transition rate that defines an opinion model into two or more transition rates, each representing the contact with heat reservoirs at different temperatures, and postulating an energy function. As the temperatures are distinct, heat fluxes are present even at the stationary state and linked to the production of entropy, the fundamental quantity that characterizes nonequilibrium states.

This is a result of the high flammability of H/O mixtures and/or the requirement for cocatalysts. In this paper, we report the synthesis of HO by means of a homogeneous catalyst, which allows a safe, one-pot synthesis in water, using only H and O.

Influenza Other Respir Viruses
January 2023
Background: Respiratory syncytial virus (RSV) is a leading cause of acute lower respiratory infection (ALRI) in young children and is of considerable burden on healthcare systems. Our study aimed to evaluate ALRI hospitalizations related to RSV in children in Portugal.
Methods: We reviewed hospitalizations potentially related to RSV in children aged <5 years from 2015 to 2018, using anonymized administrative data covering all public hospital discharges in mainland Portugal.
