An organocatalytic azide-aldehyde [3+2] cycloaddition (organo-click) reaction of a variety of enolizable aldehydes is reported. The organo-click reaction is characterized by a high rate and regioselectivity, mild reaction conditions, easily available substrates with simple operation, and excellent yields with a broad spectrum of substrates. It constitutes an alternative to the previously known ...

The present experiment was concerned with some discharge properties of single neurons in the medial geniculate body of the locally anesthetized paralyzed cat. The effect of pairing clicks with paw shock upon discharge rate and pattern was of particular concern. Twelve neurons obtained from 11 cats were studied exhaustively for periods up to 4 hr. Under control conditions, rate stationarity for ...

There are many algorithms for optimizing the search engine results, ranking takes place according to one or more parameters such as; Backward Links, Forward Links, Content, click through rate and etc. The quality and performance of these algorithms depend on the listed parameters. The ranking is one of the most important components of the search engine that represents the degree of the vitality...

Recency ranking refers to the ranking of web results by accounting for both relevance and freshness. This is particularly important for “recency sensitive” queries such as breaking news queries. In this study, we propose a set of novel click features to improve machine learned recency ranking. Rather than computing simple aggregate click through rates, we derive these features using the tempora...

Since the PoC, Intel sales and marketing teams have delivered communications to eight vertical industries across four geographies and in eight languages. When we tracked resellers in the engagement chain, we found that, in comparison with the rest of the sales pipeline, twice as many resellers advanced from leads to qualified leads. Their click-through rate for email newsletters is now three ti...

As sponsored search contributes the major income of many search engines, how to deliver ads effectively is studied intensively from both industrial and academia. Among various previous studies, many of them are keyword relevance based and few considered the underlying user intents behind queries for ads delivery. In this paper, we propose to classify search queries into different search intent ...
