摘要： A towed array ballasting unit includes a canister, an internal bladder, an external bladder, a motor valve, fluid, a shroud, and printed circuit boards. The canister includes a head endcap and an aft endcap with the internal bladder located within and attached to an internal end of a fluid channel. An external bladder is located outside the canister and attached to an external end of the fluid channel. The motor valve is attached to the aft endcap of the canister and the internal end of fluid channel. The fluid moves between the internal bladder and external bladder via the fluid channel. The shroud forms a shell around the canister, external bladder, and a connector that connects the towed array ballasting system to an array tail. The printed circuit boards execute instructions provided by a computer.

摘要： A system and method for studying cell injury mechanisms by applying biologically relevant mechanical impact to in vitro cell culture are disclosed. This approach is for maintaining consistent in vitro conditions during experiments, accommodating multiple cell populations, and monitoring each in real-time while achieving amplitude and time scale of input acceleration that mimic blunt injury cases. These multiplexed, environmental control capabilities enable characterizing the relationships between mechanical impact and cell injury in multivariate biological systems.

摘要： Thermoelectric (TE) nanocomposite material that includes at least one component consisting of nanocrystals. A TE nanocomposite material in accordance with the present invention can include, but is not limited to, multiple nanocrystalline structures, nanocrystal networks or partial networks, or multi-component materials, with some components forming connected interpenetrating networks including nanocrystalline networks. The TE nanocomposite material can be in the form of a bulk solid having semiconductor nanocrystallites that form an electrically conductive network within the material. In other embodiments, the TE nanocomposite material can be a nanocomposite thermoelectric material having one network of p-type or n-type semiconductor domains and a low thermal conductivity semiconductor or dielectric network or domains separating the p-type or n-type domains that provides efficient phonon scattering to reduce thermal conductivity while maintaining the electrical properties of the p-type or n-type semiconductor.

摘要： A computer-implemented method for evaluating a semiconductor wafer. In accordance with the present invention, using a properly designed neural network, the computer can take image data regarding the wafer at issue, plus image and electrical data regarding a prior wafer and devices fabricated on the prior wafer, to find relations to and between structural features, both known and previously unidentified, that can degrade the performance of devices fabricated on the wafer and/or can reduce the device yield of the wafer.

摘要： Methods for efficient doping of wide-bandgap (WBG) and ultrawide-bandgap (UWBG) semiconductors by implantation, and WBG and UWBG semiconductors made using the disclosed methods. A p-type semiconductor region is formed by implanting specified acceptor and donor co-dopant atoms in a predetermined ratio, e.g., two acceptors to one donor (ADA), into the semiconductor lattice. An n-type type semiconductor region is by implanting specified donor and acceptor co-dopant atoms in a predetermined ratio, e.g., two donors to one acceptor (DAD), into the semiconductor lattice. Compensator atoms are also implanted into the lattice to complete formula units in the crystal lattice structure and preserve the stoichiometry of the semiconductor material. The doped material is then annealed to activate the dopants and repair any damage to the lattice that might have occurred during implantation.

摘要： An atom interferometer that utilizes two counterpropagating continuous 3D-cooled atom beams which are directed into a vacuum chamber. Momentum-transfer laser (MTL) beams are directed into the atom beams to produce a predetermined recoil and subsequently generate an interference signal that is read by a photodetector and analyzed by a processor to provide information regarding inertial forces such as acceleration and rotation rate. Reversal of the recoil direction of the MTL beams allows for the suppression of errors in the measurement of the inertial forces.

摘要： Building blocks are provided for on-chip chemical sensors and other highly-compact photonic integrated circuits combining interband or quantum cascade lasers and detectors with passive waveguides and other components integrated on a III-V or silicon. A MWIR or LWIR laser source is evanescently coupled into a passive extended or resonant-cavity waveguide that provides evanescent coupling to a sample gas (or liquid) for spectroscopic chemical sensing. In the case of an ICL, the uppermost layer of this passive waveguide has a relatively high index of refraction that enables it to form the core of the waveguide, while the ambient air, consisting of the sample gas, functions as the top cladding layer. A fraction of the propagating light beam is absorbed by the sample gas if it contains a chemical species having a fingerprint absorption feature within the spectral linewidth of the laser emission.
