Radiocarbon Dating of Mollusk Shells: A Reply.

grassland and not going anywhere are no longer cowpaths. The photograph shows the currently used paths in the grassland bowed toward the lower left by encroaching shrubs while faint scars above reveal where the paths once passed. In the grassland these old paths are obliterated by grass; in the shrub zone they remain bare and become broader. The great broad white zones of bare ground both insid...

Pseudothrombocytopenia--a cautionary tale.

Multichannel electronic cell counters are now in widespread use in haematology laboratories. Platelet counts are given routinely by many instruments and low platelet counts generate much further investigation. A falsely low platelet count may expose the patient to unnecessary and expensive investigation and treatment, and we report two illustrative cases. The platelet counts were performed on b...

Soliloquy: a Cautionary Tale

The Soliloquy primitive, first proposed by the third author in 2007, is based on cyclic lattices. It has very good efficiency properties, both in terms of public key size and the speed of encryption and decryption. There are straightforward techniques for turning Soliloquy into a key exchange or other public-key protocols. Despite these properties, we abandoned research on Soliloquy after devel...

Twitter911: A Cautionary Tale

Researchers have argued that social media, and in particular, Twitter, can be searched to improve “situational awareness” in emergency situations; that is, to provide objective, actionable, real-time information to first-responders. Prior studies have examined cases of very rare, catastrophic emergencies that took place over many days, such as the aftermath of Hurricane Sandy. We asked instead ...
