Accessing a wider pool of user feedback leads to an increasingly more accurate analysis of user tastes, effectively creating a "rich get richer" effect. This work aims at significantly lowering the entry(More)
MicroRNAs (miRNAs) are short non-coding RNAs that postranscriptionally regulate viral and host gene expression. Reliable and simple assays for detecting and analyzing miRNAs during viral infections are critical for clinical and research purposes. A highly sensitive quantitative real-time PCR (qPCR) assay was developed. This approach, using a generic(More)
Cadherins are a superfamily of adhesion molecules that mediate Ca++ -dependent cell-cell adhesion necessary for normal morphogenesis and maintenance of tissue integrity. A classical cadherin molecule, such as E-cadherin, is a glycoprotein made up of three parts: an extracellular portion composed of five identical domains, a transmembrane portion composed of(More)
One of the most challenging recommendation tasks is recommending to a new, previously unseen user. This is known as the <i>user cold start</i> problem. Assuming certain features or attributes of users are known, one approach for handling new users is to initially model them based on their features. Motivated by an ad targeting application, this paper(More)
