Abstract: A learning system deploys, to one or more client devices, modules to be deployed in a learning environment of a respective client node. The learning environment of a respective client node may include modules for the client device (or client node) to collaborate with the central learning system and other client nodes via a distributed learning (e.g., federated learning, split learning) framework. In one embodiment, the learning system deploys an interoperable distributed learning environment for training a neural network encoder which can be used in heterogenous datasets to transform the heterogenous datasets across different institutions or entities into a common latent feature space. After training, the learning system receives data instances including a set of features and labels from different client nodes and trains a task neural network model configured to receive features in the latent space and generate an estimated label from the received data instances.

Abstract: Protein complexes are profound in various biological processes, and their ability to self-associate offers exciting opportunities for innovative biomaterials. However, the weak physical interactions within protein complexes result in limited mechanical stability and fast erosion rates, posing a significant challenge. Thus, a SAv-based hydrogel where SAv tetramers serve as crosslinking junctions is described herein. These mechanically reinforced SAv tetramers significantly enhanced the shear elasticity and decelerated the bioerosion process of the overall material. This simple approach to modulate the mechanical strength of protein complexes as crosslinking junctions present an attractive prospect for a myriad of biotechnological applications, such as biomimetic scaffolds and soft robotics.

Abstract: A learning system deploys a dynamic data conversion module (DDCM) that is customized to perform one or more extract, transform, and load (ETL) operations on the local client data that is used to train at least a portion of a master machine-learning model for the distributed learning framework. The DDCM envelopes a set of components including at least a pre-assessment toolkit and a ETL model. The pre-assessment toolkit is configured to collect statistics and abstract information from the client database of the client device and provide the statistics and abstract information to the learning system. Based on the statistics and abstract information of a respective client device, the learning system generates conversion logics and standardized vocabularies and provides them to the DDCM of the client device.

Abstract: A health condition or change in health condition of a person may be determined by processing the person's speech with a neural network. Speech from more than one time period may be processed and, in some implementations, speech from a time period may be associated with a health condition label. For each time period, a feature vector may be computed from the speech and the feature vector may be processed with a neural network to obtain a speech embedding vector. In some implementations, feature vector may include word-piece encodings and the neural network may be a transformer neural network. The speech embedding vectors may be processed with a mathematical model to determine a change in a health condition between two time periods or to determine a health condition label for a specific time period. In some implementations, the mathematical model may be a regression model or a fully-connected neural network.

Abstract: An integrated optical beam steering device includes a planar Luneburg lens that collimates beams from different inputs in different directions within the lens plane. It also includes a curved (e.g., semi-circular or arced) grating coupler that diffracts the collimated beams out of the lens plane. The beams can be steered in the plane by controlling the direction along which the lens is illuminated and out of the plane by varying the beam wavelength. Unlike other beam steering devices, this device can operate over an extremely wide field of view—up to 180°—without any aberrations off boresight. In other words, the beam quality is uniform in all directions, unlike with aplanatic lenses, thanks to the circular symmetry of the planar Luneburg lens, which may be composed of subwavelength features. The lens is also robust to misalignment and fabrication imperfections and can be made using standard CMOS processes.

Abstract: The methods described herein, referred to as particle-templated emulsification (PTE), provide an improved approach for generating a monodisperse emulsion that encapsulates target particles of interest without requiring the use of a microfluidic device. Monodisperse droplets may be effectively obtained by using monodisperse particles to template the formation of droplets, which can include, e.g., monodisperse single-emulsion droplets, multiple-emulsion droplets, or Giant Unilamellar Vesicles (GUV), without destroying the integrity of the droplets.
