Synthetic nitrogen fertilizer has been a double-edged sword, greatly improving human nutrition during the 20th century but also posing major human health and environmental challenges for the 21st century. In August 2013, about 160 agronomists, scientists, extension agents, crop advisors, economists, social scientists, farmers, representatives of regulatory agencies and nongovernmental organizat...

Vulnerabilities in browser extensions put users at risk by providing a way for website and network attackers to gain access to users’ private data and credentials. Extensions can also introduce vulnerabilities into the websites that they modify.

The widespread interest in provider-provisioned Virtual Private Network (VPN) solutions lead to memos proposing different and overlapping solutions. The IETF working groups (first Provider Provisioned VPNs and later Layer 2 VPNs and Layer 3 VPNs) have discussed these proposals and documented specifications.

We introduce a methodology for establishing a connection between two nodes of a broadband network, that allows for securing sufficient resources at every intermediate node along the selected route, and thereby guarantee Quality of Service. We describe how a Virtual Path (VP) mechanism may be implemented within our framework, and compare the performance achieved by such a scheme with that of a V...

The limited audio bandwidth of narrowband telephone speech degrades the speech quality. This paper proposes a method that extends the bandwidth of telephone speech to the frequency range 0–300 Hz. The lowest harmonics of voiced speech are generated using sinusoidal synthesis. The energy in the extension band is estimated from spectral features using a Gaussian mixture model. The amplitudes and ...
