Characterizing genetic diversity within and between populations has broad applications in studies of human disease and evolution. We propose a new approach, spatial ancestry analysis, for the modeling of genotypes in two-or three-dimensional space. In spatial ancestry analysis (SPA), we explicitly model the spatial distribution of each SNP by assigning an allele frequency as a continuous function in geographic space. We show that the explicit modeling of the allele frequency allows individuals to be localized on the map on the basis of their genetic information alone. We apply our SPA method to a European and a worldwide population genetic variation data set and identify SNPs showing large gradients in allele frequency, and we suggest these as candidate regions under selection. These regions include SNPs in the well-characterized LCT region, as well as at loci including FOXP2, OCA2 and LRP1B. © 2012 Nature America, Inc. All rights reserved. Source

This review brings together two fundamental, but unreconciled, aspects of human language: embodiment and compositionality.One major scientific advance in recent decades has been Embodiment - the realization that scientific understanding of mind and language entails detailed modeling of the human brain and how it evolved to control a physical body in a social community.The ability to learn and use language is one of the most characteristically human traits. Many animals signal, but only people can express and understand an essentially unbounded range of messages. The technical term for the ability of human language to support all these messages from a few dozen alphabetic symbols is Compositionality.Rigor is essential for the advancement of any science, but there has been essentially no overlap between efforts to formalize language compositionality and the manifest embodiment of thought. Recent developments suggest that it is feasible to formalize the compositionality of embodied language, but that this requires a focus on conceptual composition and better understanding of contextual best-fit. © 2010 Elsevier B.V.

Analysis of the audio component in multimedia data is disclosed. Rooms can be described through room impulse responses (RIR), the fingerprint of a specific room. The method uses machine learning techniques to identify rooms from ordinary audio recordings.

The 16th ACM SIGCOMM Internet Measurement Conference (IMC), sponsored by ACM SIGCOMM, in cooperation with USENIX, is to be held in Santa Monica, CA, November 14-16, 2016. This proposal requests funding to assist approximately 10-12 graduate students from US institutions who attend this conference. IMC is the primary venue for presenting new research results on collecting and analyzing measurements of the Internet. Attending conferences such as IMC is of paramount importance for graduate students pursuing research in the field. Authors have the opportunity to present their work and all attendees have a chance to interact with many others performing leading-edge research in the field.

Intellectual Merit: This proposal will serve to widen the audience attending the Internet Measurement Conference (IMC), raising the level of interaction and the potential for new collaboration, new investigations, and higher quality research. Given the rising cost of travel, the grant will enable students (who otherwise do not have sufficient funds) to attend the conference.

Broader Impacts: This proposal, by enabling students to attend who might not otherwise be able, will increase the dissemination of the conferences research results to a larger and more diverse audience. It also integrates research and education of graduate students by allowing students to observe high-quality presentations and interact with senior researchers in the field. By giving preference in grant awards to women and minority students, we hope to widen the participation among these underrepresented groups. Furthermore, by advertising to a wide range of colleges and universities, participants from a more diverse set of institutions should be able to attend and benefit from the conference.

This project provides support for the 2016 Workshop on the Economics of Information Security (WEIS). WEIS fosters cross-disciplinary, cross-sector (i.e., academia, industry, nonprofit, and government), and cross-national discussion on information security. The focus on the economics of information security was chosen not only because of its intrinsic importance, but also because of its basis for bringing together social, computer, and information scientists and engineers to share knowledge, information and methods from their respective domains. WEIS covers issues that are core to the NSFs Secure and Trustworthy Cyberspace (SaTC) program, and spans both the Computer and Information Science and Engineering (CISE) and Social, Behavioral and Economic Sciences (SBE) Directorates within the Foundation.

The WEIS conference draws a 50/50 split between US and European participants, with a small number of participants from Asia. The venue rotates between US and European locations, with two years in the US for every year in Europe.

All funds from this grant will go towards supporting US undergraduate and graduate student attendance at the WEIS conference, to be held in June 2016 at the University of California, Berkeley. This project will thus provide US students with valuable opportunities for students to meet and interact with notable researchers, thereby furthering their own research careers.
