TL;DR: Results show that VoiceLive is robust to different phone placements and is compatible to different sampling rates and phone models, and uses such unique TDoA dynamic which doesn't exist under replay attacks for liveness detection.
Abstract: Voice authentication is drawing increasing attention and becomes an attractive alternative to passwords for mobile authentication. Recent advances in mobile technology further accelerate the adoption of voice biometrics in an array of diverse mobile applications. However, recent studies show that voice authentication is vulnerable to replay attacks, where an adversary can spoof a voice authentication system using a pre-recorded voice sample collected from the victim. In this paper, we propose VoiceLive, a practical liveness detection system for voice authentication on smartphones. VoiceLive detects a live user by leveraging the user's unique vocal system and the stereo recording of smartphones. In particular, with the phone closely placed to a user's mouth, it captures time-difference-of-arrival (TDoA) changes in a sequence of phoneme sounds to the two microphones of the phone, and uses such unique TDoA dynamic which doesn't exist under replay attacks for liveness detection. VoiceLive is practical as it doesn't require additional hardware but two-channel stereo recording that is supported by virtually all smartphones. Our experimental evaluation with 12 participants and different types of phones shows that VoiceLive achieves over 99% detection accuracy at around 1% Equal Error Rate (EER). Results also show that VoiceLive is robust to different phone placements and is compatible to different sampling rates and phone models.

TL;DR: This article showed that the upper ocean around the Loop Current warmed prior to hurricane Wilma's entrance into the Gulf of Mexico due to increased volume and heat transports through the Yucatan Channel produced by storm-induced convergences in the northwestern Caribbean Sea.
Abstract: [1] Hurricanes mix and cool the upper ocean, as shown here in observations and modeling of the Caribbean Sea and the Gulf of Mexico during the passage of hurricane Wilma. Curiously, the upper ocean around the Loop Current warmed prior to Wilma's entrance into the Gulf. The major cause was increased volume and heat transports through the Yucatan Channel produced by storm-induced convergences in the northwestern Caribbean Sea. Such oceanic variability may have important impacts on hurricane predictions.

TL;DR: Experimental results indicate that this CNT-graphene structure has the potential towards three-dimensional (3D) graphene-CNT multi-stack structures for high-performance supercapacitor applications.
Abstract: This paper describes the fabrication and characterization of a hybrid nanostructure comprised of carbon nanotubes (CNTs) grown on graphene layers for supercapacitor applications. The entire nanostructure (CNTs and graphene) was fabricated via atmospheric pressure chemical vapor deposition (APCVD) and designed to minimize self-aggregation of the graphene and CNTs. Growth parameters of the CNTs were optimized by adjusting the gas flow rates of hydrogen and methane to control the simultaneous, competing reactions of carbon formation toward CNT growth and hydrogenation which suppresses CNT growth via hydrogen etching of carbon. Characterization of the supercapacitor performance of the CNT–graphene hybrid nanostructure indicated that the average measured capacitance of a fabricated graphene–CNT structure was 653.7 μF cm − 2 at 10 mV s − 1 with a standard rectangular cyclic voltammetry curve. Rapid charging–discharging characteristics (mV s − 1) were exhibited with a capacitance of approximately 75% (490.3 μF cm − 2). These experimental results indicate that this CNT–graphene structure has the potential towards three-dimensional (3D) graphene–CNT multi-stack structures for high-performance supercapacitors.
