The present disclosure describes a technology platform for creating and updating records of resources in a ledger. To create a record, a tenant organization may prepare a record to write to the ledger that may be flagged as temporary. Metadata may be added to the record, which flags the record as temporary. The metadata may comprise a unique code and an identification of a user that can approve the temporary record. The unique code and the identification may be sent, by the technology platform, to a device associated with one or more approving devices. Upon receiving the code and the identification of the transaction, the device may sign the unique code and invoke a routine based on the identification. The routine may fetch the temporary record. The device may compare the unique code to a code stored in the metadata of the temporary record. Upon valid verification of the unique code, the device may indicate authorization of the write. Based on the authorization, a proxy node associated with the technology platform may write a definitive record to the ledger based on the temporary record.

Gas analyzer and method for measuring nitrogen oxides in an exhaust gas, wherein to measure the nitrogen oxides, ozone is generated from oxygen, the exhaust gas is treated with the ozone generated to convert nitrogen monoxide within the exhaust gas into nitrogen dioxide, the nitrogen dioxide concentration in the treated exhaust gas is measured photometrically using a first light-emitting diode which emits with a central wavelength between 350 nm and 500 nm and output as the nitrogen oxide concentration in the exhaust gas, and the ozone concentration in the treated exhaust gas is measured photometrically using a second light-emitting diode which emits with a central wavelength between 250 nm and 265 nm, where generation of the ozone using the measured ozone concentration as an actual value is regulated to a prespecified setpoint value to enable reliable continuous measurement of nitrogen oxides in exhaust gases with a low outlay on equipment.

A system and method for computationally tractable prediction of protein-ligand interactions and their bioactivity. According to an embodiment, the system and method comprise two machine learning processing streams and concatenating their outputs. One of the machine learning streams is trained using information about ligands and their bioactivity interactions with proteins. The other machine learning stream is trained using information about proteins and their bioactivity interactions with ligands. After the machine learning algorithms for each stream have been trained, they can be used to predict the bioactivity of a given protein-ligand pair by inputting a specified ligand into the ligand processing stream and a specified protein into the protein processing stream. The machine learning algorithms of each stream predict possible protein-ligand bioactivity interactions based on the training data.

A strip for an electronic device senses a liquid sample. The strip includes a substrate having a first surface, a plurality of protrusions disposed on the first surface, and each having a width, and a hydrophilic layer having a layer surface disposed on the first surface and the plurality of protrusions, and having a second surface opposite to the layer surface, whereby the liquid sample and the second surface have a contact angle therebetween ranging from 2 to 85 degrees when the liquid sample is disposed on the hydrophilic layer.

There is provided a separation method in which a target component in a solution can be separated simply but safely and efficiently without contamination from the environment. This method includes: providing a solution containing a target component, and a reaction reagent; while continuously feeding the solution and the reaction reagent to a flow path, intermittently injecting bubbles into the flow path to produce a gas-liquid slug flow in which a mixed liquid containing the solution and the reaction reagent is segmented into a plurality of droplets by the bubbles; continuing the feed of the gas-liquid slug flow in the flow path, thereby facilitating the mixing of the solution and the reaction reagent, and the gasification of the target component by the mixing, in each droplet, and the movement of a target component-derived gas produced by the gasification to the bubbles; and recovering the target component-derived gas with an absorbing liquid.
