Arctic Is Experiencing a Warmer “New Normal,” NOAA Reports

A warmer Arctic means change for all.

horrific end, foiling yet another search for a Northwest Passage. Despite dozens of rescue missions in the following years, none of Franklin’s crew was seen alive again. Yet it was those missions that finally led to the mapping of a water route to the Orient— albeit an ice-clogged one. The centuries-long quest for the fabled Northwest Passage proved quixotic for generations of explorers, but wh...

The Arctic shifts to a new normal

A New Skew-normal Density

We present a new skew-normal distribution, denoted by NSN($lambada$). We first derive the density and moment generating function of NSN($lambada$). The properties of SN($lambada$), the known skew-normal distribution of Azzalini, and NSN($lambada$) are compared with each other. Finally, a numerical example for testing about the parameter $lambada$ in NSN($lambada$) is given. ...

On a New Bimodal Normal Family

The unimodal distributions are frequently used in the theorical statistical studies. But in applied statistics, there are many situations in which the unimodal distributions can not be fitted to the data. For example, the distribution of the data outside the control zone in quality control or outlier observations in linear models and time series may require to be a bimodal. These situations, oc...

Vitamin D: Is There a New Era?

  Background: In recent decades, much interest has been focused on investigating new roles of vitamin D in human body beyond the mineral-ion homeostasis. Methods: By searching medical databases such as PubMed, over 16000 articles were found which have been published since 2000 on novel aspects of vitamin D in health and diseases. Results: Of great interest was the effects of vitamin D on ...
