Abstract: Compositions including solid forms of polypeptides such as crystalline antibodies, and related methods, are generally described. The compositions may include carriers such as hydrogels that at least partially encapsulate the solid form of the polypeptides (e.g., crystals, amorphous solids). Encapsulation with certain of the materials described may result in compositions containing relatively high loadings of polypeptides while in some instances retaining structural and functional properties of the polypeptides useful for certain types of administration to subjects (e.g., for prophylactic or therapeutic applications). In some instances, compositions having relatively low dynamic viscosities while having relatively high polypeptide loadings are provided.

Abstract: A micro-probe laser frequency modulation interferometric ranging method and system, under the premise of not introducing an absolute laser rangefinder to introduce new uncertainties, continuously and slowly changes the modulated laser wavelength, resulting in a continuous periodic phase change in the interference signal obtained by the detector. The laser modulation absorption spectrum shifts from the initial locked absorption peak to another locked peak, and the wavelength changes of the two locked absorption peaks before and after are obtained by checking the table. Meanwhile, calculating the phase difference demodulated by the phase generated carrier (PGC) before and after, and the initial length of optical dead-path is calculated using wavelength scanning technology. Afterwards, utilizing the advantages of high relative distance measurement accuracy of micro-probe fiber optic laser interferometer, real-time measurement of the measured distance is achieved.
Abstract: The present invention relates to a method of reducing blind decoding attempts by a User Equipment (UE) in a telecommunication network. The method comprises configuring a Search Space (SS) configuration to the UE. A Base Station (BS) signals one of a subset of Aggregation Levels (ALs) to be monitored based on channel quality of the UE and an associated time period, and a value of multiplication factor (k) and an associated time period. The UE iteratively monitors a Physical Downlink Control Channel (PDCCH) on the ALs signalled by the BS till the UE stops receiving a new configuration. The UE performs one of adopting an original configuration, requesting the BS for a new configuration, utilizing a default configuration or utilizing an original configuration.

Abstract: The invention describes a tsunami warning system utilizing properties of light in optical fibers within submarine telecommunication cables. Enhanced by microwave frequency modulation and High-Loss Loop Back (HLLB) techniques, this system measures photoelastic changes for more stable, long-period tsunami wave detection.
Abstract: An on-chip pulse synthesizer including an integrated photonic chip that temporally and spectrally shapes pulses of light using primarily quadratic optical nonlinearities. Through this synthesis, the light pulses undergo temporal shortening or reshaping, spectral broadening, wavelength conversion, or a combination thereof. A key aspect of this synthesis is the mode engineering of the waveguides, which includes converting the pump source mode to the relevant mode in the nonlinear optical region and tailoring the waveguide geometry and material stack to enable dispersion-engineering as well as engineering of the phase matching for various nonlinear processes.

Abstract: Component errors prevent linear photonic circuits from being scaled to large sizes. These errors can be compensated by programming the components in an order corresponding to nulling operations on a target matrix X through Givens rotations X?T†X, X?XT†. Nulling is implemented on hardware through measurements with feedback, in a way that builds up the target matrix even in the presence of hardware errors. This programming works with unknown errors and without internal sources or detectors in the circuit. Modifying the photonic circuit architecture can reduce the effect of errors still further, in some cases even rendering the hardware asymptotically perfect in the large-size limit. These modifications include adding a third directional coupler or crossing after each Mach-Zehnder interferometer in the circuit and a photonic implementation of the generalized FFT fractal.

Abstract: At least partial function of a human limb is restored by surgically removing at least a portion of an injured or diseased human limb from a surgical site of an individual and transplanting a selected muscle into the remaining biological body of the individual, followed by contacting the transplanted selected muscle, or an associated nerve, with an electrode, to thereby control a device, such as a prosthetic limb, linked to the electrode. Simulating proprioceptive sensory feedback from a device includes mechanically linking at least one pair of agonist and antagonist muscles, wherein a nerve innervates each muscle, and supporting each pair with a support, whereby contraction of the agonist muscle of each pair will cause extension of the paired antagonist muscle. An electrode is implanted in a muscle of each pair and electrically connected to a motor controller of the device, thereby simulating proprioceptive sensory feedback from the device.
