Controlling the tides

The tides of Titan.

We have detected in Cassini spacecraft data the signature of the periodic tidal stresses within Titan, driven by the eccentricity (e = 0.028) of its 16-day orbit around Saturn. Precise measurements of the acceleration of Cassini during six close flybys between 2006 and 2011 have revealed that Titan responds to the variable tidal field exerted by Saturn with periodic changes of its quadrupole gr...

The Tides of EDA

IT WAS A GREAT HONOR to celebrate the 40th anniversary of the Design Automation Conference with a keynote lecture intended to place in perspective the most relevant research results presented at DAC in all these years and to identify trends and challenges for the future of electronic design automation (EDA). Going through the DAC proceedings, hunting for relevant papers, was indeed a formidable...

Tides in the Weddell Sea

Toxic tides.

4-Hydroxyanisole (4-OHA) was administered to C57Bl/lOJ mice in which B16 melanoma or Lewis lung carcinoma had been implanted s.c. or i.m. The drug had the largest antitumour effect against B16 melanoma growing s.c. and a smaller antitumour effect against B16 melanoma or Lewis lung carcinoma growing i.m. In the treatment regimens where drug was administered only after tumour implantation, a sign...
