Competence, Problem Behavior, and the Effects of Having No Friends, Aggressive Friends, or Nonaggressive Friends: A Four-Year Longitudinal Study

Phytoestrogens. Friends or foes?

BioInformatics Pipeline Alternative Splicing Services (BIPASS) offer support to scientists interested in gathering information related to alternative splicing (AS) events. The service BIPAS–SpliceDB provides access to AS information that has been extracted a priori from various public databases and stored in a data warehouse. In contrast, the BIPAS– Align&Splice service allows scientists to sub...

Forecasting ‘‘friends forever’’: A longitudinal investigation of sustained closeness between best friends

Using data collected across 19 years, the chief goal of this study was to discover predictors of continued relational closeness between best friends. Participants were same-sex and cross-sex best friend pairs recruited from a small Midwestern college. In 1983, participants completed several tests and activities designed to assess facets of intimacy, with follow-up studies in 1987 and 2002 measu...

Beta-agonists--friends or foes?

A fast algorithm for identifying Friends-of-Friends halos

We describe a simple and fast algorithm for identifying friends-of-friends clusters and prove its correctness. The algorithm avoids unnecessary expensive neighbor queries, uses minimal memory overhead, and rejects slowdown in high over-density regions. We define our algorithm formally based on pair enumeration, a problem that has been heavily studied in fast 2-point correlation codes and our re...

Bacterial toxins: friends or foes?

Many emerging and reemerging bacterial pathogens synthesize toxins that serve as primary virulence factors. We highlight seven bacterial toxins produced by well-established or newly emergent pathogenic microbes. These toxins, which affect eukaryotic cells by a variety of means, include Staphylococcus aureus alpha-toxin, Shiga toxin, cytotoxic necrotizing factor type 1, Escherichia coli heat-sta...
