Risk Analysis, EarlyView.Abstract There are two separate conceptualizations for assessing existential risks: Planetary Boundaries (PBs) and global catastrophic risks (GCRs). While these concepts are similar in principle, their underpinning literatures tend not to engage with each other.

On the Stability of Cylindrical Tangential Discontinuity, Generation and Damping of Helical Waves [PDF]
arXiv, 2015 Stability of cylindrical interface between two ideal incompressible fluids, including the magnetic field, surface tension and gravitational field is studied in linear approximation. We found that helical waves arising both in plasma comet tails and on the vertical cylindrical water jet in the air are described by the same dispersion equation where the ...

Genotoxic Herbicide Exposures in Golden Retrievers With and Without Multicentric Lymphoma
Veterinary and Comparative Oncology, EarlyView.ABSTRACT Canine multicentric lymphoma (CML) is one of the most common malignancies in dogs. Although breed risk is important, environmental factors such as herbicides have also been implicated. The objective of this study was to determine whether genotoxic exposures to the herbicides 2,4‐D and glyphosate are associated with CML, using dogs from the ...

Defeating lethal cancer: Interrupting the ecologic and evolutionary basis of death from malignancy
CA: A Cancer Journal for Clinicians, EarlyView.Abstract Despite the advances in cancer prevention, early detection, and treatments, all of which have led to improved cancer survival, globally, there is an increased incidence in cancer‐related deaths. Although each patient and each tumor is wholly unique, the tipping point to incurable disease is common across all patients: the dual capacity for ...

The wind-sock theory of comet tails [PDF]
A method is reported for calculating the shapes of ionic comet tails that use the magnetic field along the tail to channel the tail plasma. The local momentum field in the solar wind determines magnetic field line locations along the tail.

, 1992 The comet-tail (A 2 Π i -X 2 Σ + ) system of the molecular ion 12 C 16 O + , excited in the cathode glow of a hollow-cathode discharge tube of special design, was photographed in the spectral region 3400-8500 A. Of the 17 observed bands with v'=0-8 and v″
