These samples have been generously donated by UCSF students, postdocs, and alumni, in order to offer you ideas about how to present your own skills and experiences. We make no claims that they are perfect, but we offer them as useful examples. Do not copy the text exactly. To do so is considered plagiarism. It is to your advantage to create a document that stands out from your fellow applicants...
Application of recent techniques to detect current pathogens in archival effluent samples collected and concentrated in 1987 lead to the characterization of norovirus GGII.6 Seacroft, unrecognized until 1990 in a clinical sample. Retrospective studies will likely increase our knowledge about waterborne transmission of emerging pathogens.
We consider the problem of approximating the set of eigenvalues of the covariance matrix of a multivariate distribution (equivalently, the problem of approximating the “population spectrum”), given access to samples drawn from the distribution. The eigenvalues of the covariance of a distribution contain basic information about the distribution, including the presence or lack of structure in the...
For the next two weeks, I will discuss some of the concepts of random sample which we use very frequently. These are certainly not the central focus of this course, but it is extremely important for all of us to know these concepts. We have to use these ideas throughout this quarter. First we need to know what do we mean by a random sample. Definition: The random variables X1, ..., Xn together ...

We study the problem of constructing an order over a set of elements given noisy samples. We consider two models for generating the noisy samples; in both, the distribution of samples is induced by an unknown state of nature: a permutation ρ. In Mallow’s model, r permutations πi are generated independently from ρ, each with probability proportional to e−βdK(ρ,πi), where dK(ρ, πi) is the Kemeny ...
It is often asserted that Black Americans have made no IQ gains on White Americans. Until recently, there have been no adequate data to measure trends in Black IQ. We analyzed data from nine standardization samples for four major tests of cognitive ability. These data suggest that Blacks gained 4 to 7 IQ points on non-Hispanic Whites between 1972 and 2002. Gains have been fairly uniform across ...
