Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

open access: yesAdvanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Season and Disease [PDF]

open access: yesProceedings of the Royal Society of Medicine, 1928
The seasonal variations in disease, as is the case in the spread of infective diseases generally, depend upon three primary factors: (1) the presence of the micro-organisms of adequate virulence and infectivity; (2) the means of transmission to (3) the susceptible tissues of the susceptible individual.

The Seasonality of Conflict

open access: yesConflict Management and Peace Science, 2020
This paper uses one of the largest changes to labor demand in developing countries—harvest—to examine how the returns to fighting vs. working impact the intensity of conflict. Exploiting the exogenous allocation and timing of harvest across Afghanistan, Iraq, and Pakistan, we find that the onset of harvest reduces the number of insurgent attacks by ...
