Hepatocellular Carcinoma: The Final Moments of Life

Hepatocellular carcinoma (HCC) is a wide world prevalent hepatic disease, being the third greater cancer related death cause and most of the patients are not eligible for liver transplant. Palliative care is an option for, in average, half of hepatocellular carcinoma diagnosed patients and only recently the molecular targeted drug, Sorafenib, has been introduced among the therapeutic options fo...

Eureka moments.

Winter 2004 A ll truths are easy to understand once they are discovered,” wrote astronomer Galileo Galilei. “The point is to discover them.” The 17th-century Italian is best known as the inventor of the telescope, but if he’d been drawn to the life sciences instead of the physical sciences, he might have conceived of the microscope. As it was, the idea of using lenses to see tiny rather than fa...

Frequency Moments

DEFINITION Consider a stream (i.e., an ordered list) S = a1, a2, . . . , an of elements ai ∈ [m] def = {1, 2, . . . ,m}. For i ∈ [m], its frequency fi is the number of times it occurs in S. The k-th frequency moment Fk of S, for real k > 0, is defined to be Fk(S) = ∑ i∈[m] f k i . Interpreting 0 0 as 0, we also define F0 this way, so that it equals the number of distinct elements in S. Observe ...

Nuclear Moments

Spins, electromagnetic moments and radii are basic observables characterizing a particular nucleus. We review a variety of experimental techniques currently used to measure these quantities for unstable nuclei far from stability and for isomeric nuclear states. The experiments can be traced back to two different principles: Optical high-resolution spectroscopy reveals the interaction between nu...
