Abstract: The wave number and phase velocity (shear wave speed) of ultrasound energy within an organ of interest are calculated using a herein-disclosed phase gradient calculation method. This calculation method is less sensitive to imperfections in the reverberant field distribution and requires a smaller support window, relative to earlier calculation methods based on autocorrelation. Applications are shown in simulations, phantoms, and in vivo liver.

Abstract: A shape-memory polymer that is melt-recyclable with high processability and little performance loss, in contrast to known Crosslinked semicrystalline shape-memory networks that are capable of storing large amounts of elastic energy with negligible plastic deformation but as thermosets are not easily melt-processed or recycled. In examples herein, catalyst-free isocyanate chemistry is used to prepare two linear poly(caprolactone)s with bisurea hydrogen bonding groups periodically positioned along the main chain. Compared to an entangled poly(caprolactone) homopolymer of similar molecular weight, the segmented poly(bisurea)s exhibit minimal stress relaxation when elastically strained at identical conditions. Furthermore, the materials' single relaxation times indicate chain reptation, and at sufficient temperatures, disentanglement occurs rapidly enough to perform melt-processing.

Abstract: Materials are disclosed that superconduct at high temperatures and low pressures. Methods of making and measuring the materials are also disclosed. In a particular embodiment, a nitrogen-doped (or other lightweight-atom doped) rare earth metal hydride is disclosed. Also disclosed are thermodynamic pathways to recovering materials that superconduct at room temperature and room pressure and/or at other desirable operating temperatures and pressures to enable superconductivity at conditions that make a wider range of superconductive applications practical. These and other aspects of various embodiments are disclosed herein.

Abstract: Systems and methods of driving plate loudspeakers with different parameters based on frequency region in a way similar to typical cone driver crossover networks are described. These systems and methods may be implemented using arrays of independently controlled drivers which allow a designer to emphasize or de-emphasize certain modes in certain frequency bands. Tuning the characteristics of the plate's motion can also affect the acoustical properties in a larger space rather than just at a single location. The systems and methods described herein can grant a designer a degree of control over the characteristics and performance of the plate.

Abstract: The invention provides systems and methods for improved simulation of surgical procedures, using models of anatomical organs. The models comprise models of internal components present in the anatomical organ. The models of the internal components are registered to the position which the internal component occupies in the anatomical organ, and in some embodiments the models of the anatomical organ can lose simulated physiological fluids during simulated surgery.

Abstract: A fast and dynamic waveplate is described. The present systems and methods utilize stress birefringence that generates inside a plate when force is applied on one or more sides of the plate. The force is applied using one or more actuators distributed along the side(s) of the plate. The magnitude of the force can be controlled using a control unit. A generated stress birefringence is spatially varying across the plate. By carefully adjusting the force, the plate can be converted into a waveplate with an arbitrary value of retardance that is determined by the force. Since the parameter that determines the birefringence is force, a control unit can be used to apply different combinations of force values at a sub-millisecond speed to achieve fast control of the value of the birefringence as well as an orientation in the plate.

Methods of making, isolating and using the disclosed cell preparation are also described.

Abstract: A transducer transmits into the bone a first plurality of excitation pulses at a plurality of frequencies and measures a plurality of echoes corresponding to the plurality of excitation pulses. An ultrasound machine calculates a plurality of energies each corresponding to a respective one of the plurality of echoes and identifies a lowest echo corresponding to a lowest of the plurality of energies. The ultrasound machine matches the lowest echo to a corresponding one of the first plurality of excitation pulses, the corresponding one of the first plurality of excitation pulses having a chosen frequency. The ultrasound machine generates an acoustic impulse response by deconvolving the corresponding one of the first plurality of excitation pulses with the lowest echo, and generates an updated sensing matrix by convolving the initial sensing matrix with the acoustic impulse response. Subsequent ultrasounds use the updated sensing matrix.
