Abstract: The disclosed technology can generally relate to methods for manufacturing spent coffee ground derived microbots for purifying contaminated water sources. The method for manufacturing the spent coffee ground derived microbots can include obtaining coffee grounds, magnetizing the coffee grounds, and coating the magnetized coffee ground with ascorbic acid. Magnetizing the coffee grounds can include immersing the coffee ground in a solution of iron oxide nanoparticles and ethanol, mixing the coffee grounds and the solution, and allowing the coffee grounds and the solution to sit undisturbed for a predetermined period.

Abstract: A system for gait-based user authentication, includes a processor and a memory. The memory includes instructions stored thereon, which when executed by the processor, cause the system to: access data relating to a gait of a user; provide the data as an input to an early escape network (EENet) having two or more early exits; dynamically determine by a deep Q-learning network (DQN) which of the two or more early exits of the EENet to take; dynamically determine by the EENet a predicted authentication at the determined exit; take the determined early exit by the EENet; and provide an authentication based on the predicted authentication at the determined early exit.

Abstract: Highly microporous laser fabricated three-dimensional graphene which can be prepared from a fluorinated polyimide is disclosed as a material suitable for a neural electrode, e.g., a neural stimulation device. The three-dimensional porous graphene incorporated into the device may have a multi-scale structure, which enables electrical and charge carrying properties. In some aspects, the porous graphene incorporated into the device has the following pore structure: macropores having an average pore size exceeding 50 nm; mesopores having an average pore size of 2-50 nm; micropores having an average pore size of 2 nm or less; and nanopores having an average pore size of less than 100 nm. Neural stimulation devices and methods of using the devices are also described.

Abstract: Aspects of the present disclosure generally relate to systems and processes for automated skin feature detection and analysis, and more particularly to identifying and assessing the characteristics and age of skin contusions, bruises, and other similar skin features using a deep learning model. Images of a patient's body part are captured via a digital camera with a light source. The parameters of the light source are determined, and other information is gathered, including skin color and medical history of the patient/subject. Images of an injured area are combined with contextual clinical information as inputs to a machine learning model. The machine learning model detects and estimates characteristics of skin features. In an exemplary embodiment, the machine learning model detects bruises on the skin, and estimates their age and outputs the estimate to an end user along with a measurement of the uncertainty in the estimate.

Abstract: A method of authenticating a user that includes initializing the multi-factor authentication system based on an input; presenting a challenge requesting the user to enter a specific authenticator of a sequence of authenticators stored in the multi-factor authentication system, where the stored sequence of authenticators represents a combination of a plurality of authentication factors; receiving an authenticator from the user in response to the challenge; verifying identity of the user by determining whether the received authenticator matches the specific authenticator requested by the challenge; and granting the access based on a determination that the received authenticator matches the specific authenticator requested, or denying the access based on a determination that the received authenticator does not match the specific authenticator requested.

Abstract: A method and system provide and utilize obfuscated fonts for displayable content. Responsive to a request for displayable content having text, a text portion of the requested displayable content to be obfuscated is determined. For that text portion, obfuscated fonts are provided, by retrieving obfuscated fonts or by generating obfuscated fonts from a set of obfuscated glyphs created from a plurality of glyphs representative of a plurality of characters of the text portion of the displayable content. The obfuscated fonts can be created by assigning obfuscated glyphs of the set into the obfuscated fonts in accordance with one or more messages. The obfuscated fonts are mapped by assigning a value to each obfuscated glyph in the set that is different from an original value of the glyph.
