Abstract: Systems, methods, and computer readable media for decentralized two-phase commit in a datastore or database where the methods include determining pre-validating a transaction, writing first metadata to a leader partition, the first metadata including a state indicating preparing and mutations of the transaction, and writing second metadata of a follower partition to indicate the follower partition is locked by the leader partition. The methods further include updating the state of the first metadata to indicate committed and performing the transaction on the leader partition, performing the transaction on the follower partition and unlocking the follower partition, and updating the first metadata to remove the mutations of the transaction and updating the state of the first metadata to indicate the transaction is completed. The methods may further include selecting a leader partition key and updating the state of the first metadata to indicate committed unapplied.

Abstract: Systems and methods are provided for synchronizing data. The systems and methods include operations for: storing a synchronization entry for a messaging application feature, the synchronization entry comprising a last update timestamp associated with a first update to content of the messaging application feature received from a first source; receiving a second update to the content of the messaging application feature from the first source; determining that the second update was received within a write window of the last update timestamp; in response to determining that the second update was received within the write window of the last update timestamp, preventing updating the last update timestamp; and sending the first update and the second update to a client device in response to receiving a synchronization request from the client device based on the last update timestamp.

Abstract: Systems, methods, and computer readable media for a live data migration system where the methods include accessing a command to perform a live data migration of a source datastore to a target datastore, accessing a delete operation, the delete operation indicating first data to be deleted from a datastore, and determining the datastore is stored in a source datastore. The methods further includes performing a two-phase commit delete of the first data from the source datastore and the target datastore, accessing a write operation, the write operation indicating second data, and performing a two-phase commit write of the second data to the source datastore and to the target datastore. The methods further include copying the source datastore to the target datastore, accessing a read operation, the read operation indicating third data to be read from the datastore, and performing the read operation of the third data from the target datastore.

Abstract: Disclosed herein are methods and devices for detection of bacterial HAI. Disclosed methods may be utilized for continuous in vivo monitoring of a potential bacterial infection site and may be utilized to alert patients and/or health care providers to the presence of pathogenic bacteria at an early stage of infection. Disclosed methods include utilization of recombinant bacteriophage to deliver to pathogenic bacteria a translatable genetic sequence encoding an optically detectable marker or an enzyme capable of producing an optically detectable marker. Upon detection of the optical signal produced by the marker, medical personnel may be alerted to the presence of pathogenic bacteria at the site of inquiry. Any bacterial causative agent of HAI may be detected according to disclosed methods.

Abstract: Disclosed are methods and devices for continuous in vivo monitoring of a potential bacterial infection site. Disclosed devices may be utilized to alert patients and/or health care providers to the presence of pathogenic bacteria at an early stage of a hospital acquired infection, thereby providing for earlier intervention. Disclosed methods utilize optical fibers to deliver an excitation signal to an area in which pathogenic bacteria may exist. In the presence of the excitation signal, bacterial pathogens may autofluoresce with a unique spectral signature. Upon generation of a fluorescent emission, an optically detectable emission signal may be transmitted to a detection/analysis device. Analysis of the characteristics of the emission signal produced in response to the excitation signal may be used to determine the presence or concentration of pathogens at the site of inquiry, following which real time information may be transmitted to medical personnel via a wireless transmission system.

Abstract: Disclosed herein are methods and devices for detection of hospital acquired infections. Disclosed methods may be utilized for continuous in vivo monitoring of a potential infection site and may be utilized to alert patients and/or health care providers to changes in the local environment due to the presence of a pathogen at an early stage of infection. Disclosed methods utilize ion sensitive field effect transistors (ISFETs) to detect changes in ionic concentration at the site due to the presence of a pathogen, for instance at a surgical site. When a pathogen is present, the local ionic concentration, and hence the electrical characteristics of an ISFET may change, causing a detectable signal from the ISFET. An ISFET may be associated with a biological material such as an enzyme or a specific binding partner for an expression product of a pathogen to improve detection.
