Abstract: Methods and systems are described for verifying an identity of a user through contextual knowledge-based authentication. The system described uses contextual knowledge-based authentication. By verifying an identity of a user through contextual knowledge-based authentication, the verification is both more secure and more intuitive to the user. For example, by relying on confidential and/or proprietary information, the system may generate verification questions, the answers to which are known only by the user.

Abstract: Techniques are described for managing devices, such as Internet of Things (IoT) devices, using smart contract(s) on a distributed ledger (e.g., blockchain). Smart contract(s) executing on a distributed ledger may control access to one or more devices in a home or other environment. The smart contract(s) may employ information stored on the distributed ledger and information in a transaction sent to the smart contract(s) to determine whether particular user(s) and/or process(es) may access the device(s), issue commands to the device(s), access data generated by the device(s), and/or control the device(s). The smart contract(s) may provide a secure portal through which user(s) and/or service(s) may access device(s) for command and control of such device(s), and secure access may be based on permission information that is specified or provided by an owner or operator of the device(s) and that is stored on the distributed ledger.

Abstract: Systems and methods for using hash tables generating textual prediction explanations. In some aspects, the system receives a first plurality of user profiles and a corresponding plurality of resource availability values. Each user profile includes values for a first set of features. The system processes a first machine learning model to extract an explainability vector. The first machine learning model receives as input the first set of features and outputs a resource availability value. The system, using the explainability vector, selects a subset of features having corresponding values in the explainability vector above a threshold. The system generates a set of categories based on the subset of features and a hash table including the set of categories. The hash table is indexable using a hash value generated based on values for the subset of features. The system transmits to a user system corresponding a user profile a textual prediction explanation.

Abstract: A package includes a base, a lid, and a locking mechanism. The locking mechanism includes an arm and a flexible member. The arm extends from the lid and has a first engaging structure. The member includes a flexible rib connected to a base floor, and a second engaging structure and a contact structure on a rib outer surface. The member flexes in response to a first force applied in a first direction to the contact structure and relaxes in response to absence of the first force. The member engages the first and second engaging structures based on the member being relaxed while the lid is closed. The member disengages the first and second engaging structures based on the member being flexed while the lid is closed. The lid may be opened based on applying a second force to the lid in a second direction while the member is flexed.

Abstract: Magnetic resonance and ultrasound methods can produce estimates of full rank-4 elasticity tensors (E-tensors) using suitable constraints. E-tensor estimates can be based on E-tensor symmetry conditions and a suitable E-tensor selected from among a set of E-tensors calculated using different symmetry constraints. Displacement fields used in E-tensor calculations can be noise reduced using compatibility conditions. With the selected E-tensor, various stains that are rotation invariant can be computed. In one example. an E-tensor for an in vivo brain is computed using the mechanical disturbance associated with cardiac pulsations. The selected E-tensor and associated stains. physiological disorders such as Alzheimer's disease and traumatic brain injury (TBI) and even neural activation may be more readily detected than with conventional methods that do not use the full E-tensor.
