adds new subject categories


New top subject categories for Electrical Engineering and Systems Science and Economics on the homepage of will make it easier for a broader group of researchers to share the latest information in their fields.

The Economics arXiv will begin with the single subject area of Econometrics, which focuses on providing statistical methods for quantitative analysis, and will likely expand to more subcategories in the future based on user needs and arXiv’s capacity. Postings to the category began Sept. 26.

A significant number of econometricians already regularly submit their work to the statistics domain of Submissions to the new subject category will be moderated by Victor Chernozhukov, a professor in MIT’s Department of Economics and Center for Statistics.

arXiv, the prominent preprint repository for physics and a growing number of other scientific and mathematic fields, is stewarded by Cornell University Library and supported by 220 member libraries and several scientific organizations including the Simons Foundation.

Posting began last week in the new subject category for Electrical Engineering and Systems Science (EESS), which arXiv’s Scientific Advisory Board decided to create in cooperation with the IEEE Signal Processing Society.

The new EESS category will include contributions addressing analytical and computational aspects of EESS, as well as the analysis, optimization and control of cyber-physical systems such as power grids and the Internet of Things.

Al Hero, the John H. Holland Distinguished University Professor of Electrical Engineering and Computer Science at the University of Michigan, will chair the new EESS domain, which will be sub-divided into three subcategories: Signal Processing, Image and Video Processing, and Speech and Audio Processing.

arXiv has also named Steinn Sigurdsson, professor of astronomy and astrophysics at Pennsylvania State University, as its new scientific director.

Sigurdsson’s appointment comes as arXiv’s leadership embarks on a modernization of the service, to be known as Next Generation arXiv or arXiv-NG. Earlier this month, the Heising-Simons Foundation awarded arXiv a $322,000 grant to support arXiv-NG’s design and development.

As scientific director, Sigurdsson will work with arXiv Program Director Oya Rieger to oversee and provide intellectual leadership for the operation.

“The arXiv is an invaluable resource to the physical sciences research community, and we hope to continue to facilitate rapid access to the latest research, and extend our reach to different fields” Sigurdsson said.

The grant from the Heising-Simons Foundation, which follows a $450,000 grant from the Sloan Foundation, will help fund the creation of a scalable, cost-efficient, and reliable infrastructure for the site, which currently relies on aging legacy code. The planning for arXiv-NG is expected to take three years, during which time the site will remain robust and reliable.

“The arXiv team is excited about the recent developments,” Rieger said. “Professor Sigurdsson will add further expertise to our team and the additional funds from the Heising-Simons Foundation will be instrumental as we strengthen arXiv's technology framework and add new subject domains.”
