BMJ tackles FDA's mote in eye while ignoring own beam

Probabilistic estimation while ignoring outliers

Logistic regression learns a parameterized mapping from feature vectors to probability vectors and is for example central to estimating click rates for ads on web pages. The parameter is found by minimizing the logistic loss. However minimizing any convex loss summed over a set of examples is prone to outliers. We define a versatile method for designing non-convex losses that ameliorate the eff...

Proton‐beam therapy: are physicists ignoring clinical realities?

The timely guest editorial this month is authored by the distinguished R. J. Schulz, Ph.D. from Yale University. As physicists, we must forever resist being blinded by the technology, and force ourselves to ask some critical questions. How much does this cost? How many quality-adjusted, life-years are we really buying for our patients? To whom should the bill be sent and why? What standards sho...

Mobile Mote

In many distributed sensor applications such as studying bird migration patterns, it is necessary to track down and retrieve data from a specific mobile object tagged with sensors and radio transceivers. Because these objects are mobile and operate over a wide area, it is expensive and sometimes impossible to build a single wide-area sensor network that covers all areas of operations. During pe...

Saccadic eye movements while reading music

Subjects' eye movements were measured whilst they read and performed lines of music consisting of rhythmic information only, in conventional musical notation. The relationship between the spatial pattern of the notes displayed and of the fixations made in reading them is stochastic, and similar to that in ordinary reading, but with a tendency to fixate salient details of the notation such as no...
