Abstract: Detection of synthetic content in portrait videos, e.g., deep fakes, is achieved. Detectors blindly utilizing deep learning are not effective in catching fake content, as generative models produce realistic results. However, biological signals hidden in portrait videos which are neither spatially nor temporally preserved in fake content, can be used as implicit descriptors of authenticity. 99.39% accuracy in pairwise separation is achieved. A generalized classifier for fake content is formulated by analyzing signal transformations and corresponding feature sets. Signal maps are generated, and a CNN employed to improve the classifier for detecting synthetic content. Evaluation on several datasets produced superior detection rates against baselines, independent of the source generator, or properties of available fake content.

Abstract: A microfluidic-based device and system is disclosed for the high-throughput intracellular delivery of biomolecular cargo to cells (eukaryotic or prokaryotic) or enveloped viruses. Cargo integration occurs due to transient membrane permeabilization by exposure to bulk acoustic waves (BAWs) transduced from surface acoustic waves (SAWs) generated by a rapidly oscillating piezoelectric substrate. In this approach, temporary pores are established across the cellular membrane as cells are partially deformed and squeezed or subject to shearing forces as they travel through the vibrational modes created within the microfludic channel(s) of the device.
