In recent years, the number of recommender systems used in online shops has strongly increased and is becoming an important success factor for electronic commerce applications. A recommender system can be utilized to suggest similar related or potentially interesting products for a given customer or a set of products for a marketing campaign. This paper shows how seasonal products can be identi...

The version 6 TRMM rainfall products showed significant improvements on satellite rain retrievals as compared to rain gauge observations. The differences between TRMM TMI rain products and gauge observations are less than 10% over Florida, Texas, Kwajalein, and Darwin ground validation sites for the 8-year period from January 1998 to December 2005. The rain differences between Version 6 TMI and...

This report updates the 2014 recommendations of the Advisory Committee on Immunization Practices (ACIP) regarding the use of seasonal influenza vaccines.

Unprecedented global surveillance of viruses will result in massive sequence data sets that require new statistical methods. These data sets press the limits of Bayesian phylogenetics as the high-dimensional parameters that comprise a phylogenetic tree increase the already sizable computational burden of these techniques. This burden often results in partitioning the data set, for example, by g...

SAD is a state of depression induced by a lack of sufficient sunlight that occurs at high latitudes during the fall and winter. SAD causes people to be risk-adverse. Granting agencies of high latitude countries should time high-risk research competitions so they do not coincide with the SAD months.

BACKGROUND As observed during the 2009 pandemic, a novel influenza virus can spread globally before the epidemic peaks locally. As consistencies in the relative timing and direction of spread could form the basis for an early alert system, the objectives of this study were to use the case-based reporting system for laboratory confirmed influenza from the Canadian FluWatch surveillance program t...

allergic rhinitis is the most common cause of allergic diseases. the recent guidelines of allergic rhinitis and its impact on asthma (aria) group, classified it to intermittent (less than 4 days per week and for less than 4 weeks) and persistent (more than 4 days per week or lasting more than 4 weeks regardless of the number of days per week). the present study evaluates the patients with aria ...
