Human Activity Makes India’s Coastlines More Vulnerable

Complex social contagion makes networks more vulnerable to disease outbreaks

Social network analysis is now widely used to investigate the dynamics of infectious disease spread. Vaccination dramatically disrupts disease transmission on a contact network, and indeed, high vaccination rates can potentially halt disease transmission altogether. Here, we build on mounting evidence that health behaviors - such as vaccination, and refusal thereof - can spread across social ne...

Making Light Forces Smaller/More Dispersible Has Benefits But Makes Them More Vulnerable and Less Capable

IN CHAPTER THREE WE EXAMINED some relatively near-term upgrades to improve the capability of light forces when placed in rapid-reaction missions, working mostly with RFPI concepts and technologies within the context of ACTDs. But what would be the impact of changing concepts—for example, making light forces smaller and more dispersed? Given that the dramatic improvements in precision-guided and...

Polymeric Gas Separation Membranes: What Makes them Industrially more Attractive?

What makes hospitalized patients more vulnerable and increases their risk of experiencing an adverse event?

OBJECTIVE To analyze the relationship between the appearance of adverse events (AEs) and both patient comorbidities and the use of medical devices. DESIGN Retrospective medical records review study. SETTING Twenty-four Spanish public hospitals. PARTICIPANTS Clinical records of 5624 discharged patients. MAIN OUTCOME MEASURE Incidence of AEs. RESULTS Patients aged >65 have 2.4 times the...

Pleistocene megafaunal interaction networks became more vulnerable after human arrival.

The end of the Pleistocene was marked by the extinction of almost all large land mammals worldwide except in Africa. Although the debate on Pleistocene extinctions has focused on the roles of climate change and humans, the impact of perturbations depends on properties of ecological communities, such as species composition and the organization of ecological interactions. Here, we combined palaeo...
