Abstract: A system may include a chamber with a main sub-chamber and a first porous membrane separating a first sub-chamber from the main sub-chamber. The system may include a fluid in the chamber and an input directing inflow into main sub-chamber proximate an entry end of the chamber. The system may include a first output permitting outflow from the first sub-chamber proximate an exit end of the chamber wherein a molecule entering at the entry end must traverse a length of the chamber to exit at the exit end.

Abstract: A validation method applied to sensor data prior to submitting to a blockchain, a computer program product, and a system for validating chemical data. One embodiment may comprise receiving a sensor captured result at an application, applying the sensor captured result to a domain-specific statistical model of expected range of variability of measured results to extract a distribution of expected sensor values, computing a confidence value in the sensor captured result using the domain-specific statistical model, validating the confidence value against a required threshold of confidence, and submitting the sensor captured result for appending to the blockchain if the confidence level is validated against the threshold of confidence.

Abstract: A grey-scale tomography of a sample is obtained and a capillary network model (CNM) geometry of the sample is produced, using a capillary network extractor, based on the grey-scale tomography. A fluid flow simulation is performed, using a flow simulator, to generate flow property fields based on the capillary network model (CNM) geometry. A mineralization simulation is performed influenced by results of the flow property fields to generate a modified capillary geometry that represents the capillary network model (CNM) geometry at a future point in time.

Abstract: Systems and methods for predicting fluid flow of porous media are provided. In implementations, a method includes: accessing, by a computing device, a capillary network representation of a porous medium sample; generating, by the computing device, a set of simplified network representations from the capillary network representation; determining, by the computing device, simulated fluid flow properties of each of the simplified network representations using a simulator to perform fluid flow simulations; and training, by the computing device, a neural network (NN) model utilizing the set of simplified network representations as inputs and the simulated fluid flow properties as model targets, thereby generating a trained NN model for predicting fluid flow properties of the porous medium.

Abstract: Devices and methods for controlling collection of liquid sample are described. In an example, a microfluidic device can include an analytical device and an actuator. The actuator can be connected to the analytical device. The actuator can be operable to absorb fluid. The actuator can guide the absorbed fluid to an input layer of the analytical device. The actuator can deform in response to an occurrence of an absorption condition. A degree of deformation of the actuator indicates a volume of fluid collected by the analytical device.
