Scheduling conflict notification
One or more techniques and/or systems are provided for surfacing scheduling conflicts and/or for facilitating appointment scheduling based upon conflict detection. A user may maintain user appointment data comprising user appointments (e.g., calendar entries within a work calendar). Because user activity may not be fully reflected in the appointment data (e.g., no calendar entries for routine grocery shopping, soccer practice, etc.), potential conflicts may exist between user appointments and the true availability of the user. Accordingly, user signals (e.g., email(s), location check-ins, etc. associated with soccer practice) may be evaluated to generate a user inferred behavior pattern that may be used to identify a potential conflict with a user appointment (e.g., where the user consents to the gathering and/or use of such user signals). A warning of the potential conflict may be surfaced to the user (e.g., a Tuesday dinner calendar meeting conflicts with routine soccer practice on Tuesday evenings). |

Optical holographic addressing of atomic quantum bits
Atoms and atom-like quantum emitters are promising for quantum sensing, computing, and communications. Lasers and microscopes enable high-fidelity quantum control of the atomic quantum bits (qubits). However, it is challenging to scale up individual quantum control to enough atomic quantum nodes for implementing useful and practical quantum algorithms. Here, we introduce methods and systems to holographically implement large-scale quantum circuits that individually address atomic quantum nodes. These methods enable implementation of quantum circuits over large, multi-dimensional arrays of atomic qubits at rates of thousands to millions of quantum circuit layers per second. The quantum circuit layers are encoded in multiplexed holograms displayed on a slow SLM and retrieved by fast interrogation to produce spatial distributions that operate on the qubit array. This technology can also be used for optically addressing objects such as biological cells and on-chip photonic components for optical tweezers, opto-genetics, optical computing, and optical neural networks. |

A computerized operating system begins a garbage-collection operation by collecting a set of “garbage” data objects to be deleted. Certain of these objects are identified, either by an embedded identifier or by an entry in a sensitive-objects data structure, as containing sensitive data. When the garbage collector moves or deletes a sensitive object during the garbage-collection procedure, the collector zeroes out any residual data left at the object's original location in memory or secondary storage. If the collector determines that the object no longer has any connection to other software entities, the collector zeroes out the storage locations of all identified instances of the object. The collector then updates the data structure to indicate the current location of sensitive objects that have been moved or copied, and deletes entries for zeroed out instances of deleted sensitive objects. |

Ransomware infection detection in filesystems
Described herein is a system that detects ransomware infection in filesystems. The system detects ransomware infection by using backup data of machines. The system detects ransomware infection in two stages. In the first stage, the system analyzes a filesystem's behavior. The filesystem's behavior can be obtained by loading the backup data and crawling the filesystem to create a filesystem metadata including information about file operations during a time interval. The filesystem determines a pattern of the file operations and compares the pattern to a normal patter to analyze the filesystem's behavior. If the filesystem's behavior is abnormal, the system proceeds to the second stage to analyze the content of the files to look for signs of encryption in the filesystem. The system combines the analysis of both stages to determine whether the filesystem is infected by ransomware. |

Parallel pseudo infinite monotonic timeline clock
Techniques are included for providing a parallel pseudo infinite timeline monotonic clock that may be used to determine time and durations. A system clock is used to obtain an original time instant that anchors the pseudo infinite timeline to be parallel to a timeline of the system clock.

Method and system for low sampling rate electrical load disaggregation
This disclosure relates generally to method and system for low sampling rate electrical load disaggregation. At low sampling rates, disaggregation of energy load is challenging due to unavailability of events and signatures of the constituent loads. The disclosed energy disaggregation technique receives aggregated load data from a utility meter and sequentially obtains training data for determining disaggregated energy load at low sampling rate. Dictionaries are used to characterize the different loads in terms of power values and time of operation. The obtained dictionary coefficients are treated as graph signals and graph smoothness is used for propagating the coefficients from the training phase to the test phase by formulating an optimization model. The derivation of the optimization model identifies the load of interest and estimate their power consumption based on optimization model constraints. This method achieves accuracy greater than 70% for the loads of interest at low sampling rates. |
