The present status of abundance information for elements in meteorites and in the Sun is
reviewed, and a new table of abundances of the elements, which should be characteristic of …

The concept of the metabolic syndrome has now been in existence for several decades;
however, it has only been since some agreement on definitions of the syndrome was reached …

A global medical crisis is unfolding as antibiotics lose effectiveness against a growing
number of bacterial pathogens. Horizontal gene transfer (HGT) contributes significantly to the …

β-site APP-cleaving enzyme (BACE) is required for production of the Alzheimer's disease (AD)-associated
Aβ protein. BACE levels are elevated in AD brain, and increasing evidence …

Climate change over the past∼ 30 years has produced numerous shifts in the distributions
and abundances of species 1, 2 and has been implicated in one species-level extinction 3. …

This book provides the most comprehensive treatment to date of microeconometrics, the
analysis of individual-level data on the economic behavior of individuals or firms using …

Students in both social and natural sciences often seek regression methods to explain the
frequency of events, such as visits to a doctor, auto accidents, or new patents awarded. This …

Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background
of GWs modulates pulsar arrival times and manifests as a stochastic process, common …

In this article we propose a variance estimator for the OLS estimator as well as for nonlinear
estimators such as logit, probit, and GMM. This variance estimator enables cluster-robust …

This paper deals with specification, estimation and tests of single equation reduced form
type equations in which the dependent variable takes only non‐negative integer values. …
