Abstract: An ultrasound scanning system includes a graphical user interface that provides visually intuitive feedback to a user to assist the user in properly aligning an ultrasound scanner to a desired acquisition state. In addition to providing pose information, the feedback may direct the user as to a target contact force applied by the ultrasound scanner to a surface undergoing a scan.
Abstract: Some embodiments herein provide compositions and methods for expressing secreted and cell-surface-bound polypeptides in a single cell. In some embodiments, secreted and cell-surface polypeptide are produced from a single polynucleotide. The polynucleotide can comprise a sequence (or sequence encoding a polypeptide) that mediates separation of a membrane anchor from the polypeptide. In some embodiments, a desired ratio of secreted to surface-bound polypeptide is obtained by selecting a sequence that mediates a desired level of separation of the membrane anchor from the polypeptide.

Abstract: An encoder generates a compressed data sequence from an original data sequence using many-to-one mapping independently of a source model associated with the original data sequence and without extracting the source model. A decoder uses both the source model associated with the original data sequence and the mapping applied during compression that is devoid of, in substance, the source model, to regenerate, at least in part, the original uncompressed data sequence from the compressed data sequence that does not include a significant portion of the source model.
Abstract: Network coding and multiple packet reception (MPR) are used together in a wireless network. In at least one implementation, a novel medium access control (MAC) protocol is provided that enhances throughput in a wireless mesh network that uses network coding and MPR by providing fairness to information flows, rather than fairness to individual nodes.

Abstract: Methods and apparatus for modulating a particle pulse include a succession of Hermite-Gaussian optical modes that effectively construct a three-dimensional optical trap in the particle pulse's rest frame. Optical incidence angles between the propagation of the particle pulse and the optical pulse are tuned for improved compression. Particles pulses that can be modulated by these methods and apparatus include charged particles and particles with non-zero polarizability in the Rayleigh regime. Exact solutions to Maxwell's equations for first-order Hermite-Gaussian beams demonstrate single-electron pulse compression factors of more than 100 in both longitudinal and transverse dimensions. The methods and apparatus are useful in ultrafast electron imaging for both single- and multi-electron pulse compression, and as a means of circumventing temporal distortions in magnetic lenses when focusing ultra-short electron pulses.
