Notably, the rate of removal of the encryption keys differs from the rate of cache eviction for the decryption keys. Thereafter, clear data is encrypted with a cipher to produce cipher text, and the cipher is encrypted with a selected key encryption key from the pool. Finally, in response to an access request for the clear data, an attempt to locate in the cache a key decryption key for the encrypted cipher is made. If attempt fails, the key decryption key is retrieved from remote memory. Finally, the encrypted cipher is decrypted with the located key, and the cipher text decrypted to produce the clear data. |

Equivocation augmentation dynamic secrecy system
Shannon's equivocation, the conditional entropy of key or message with respect to a specific ciphertext, is the primary indicator of the security of any secrecy system, in that when key equivocation H E (K) or message equivocation H E (M) attain log 0 (or 1) under a brute-force attack, the system is compromised and has no security. We propose a simplistic equivocation definition of security which distinguishes between “secure/unsolvable” and “insecure/solvable” encipherments. Whilst equivocation may be used practically in a passive manner to cryptanalyse finite-length key “insecure/solvable” secrecy systems to determine the length of ciphertext required to compromise the secrecy system, the invention in this patent offers a cryptographic design framework which allows for the equivocation of finite-length key systems to be actively engineered using equivocation augmentation, such that the residual key and message equivocation of any cryptosystem may be continuously augmented at a faster rate than it is lost, effectively ensuring that equivocation can never attain log 0. In short, it allows for the encryption of any length of message with any finite length key into a ciphertext with “secure/unsolvable” security characteristics. Alternatively, it allows for the cryptographic engineering of information theoretic security in all finite length key systems. The invention is primarily aimed at solving two major problems: (a) a viable practical security solution against future quantum computing/artificial intelligence threats (the QC/AI problem), and (b) a viable practical security solution to the privacy/national interest dichotomy problem, in that it allows for the engineering of security systems which are capable of simultaneously supporting both the absolute privacy of individual users and the security interests of the user group at large. Various methods, apparatuses, and systems are described which allow for the implementation of a “secure/unsolvable” secrecy system which is fast, extensible, simple to implement in hardware and software, and able to be incorporated by or with any existing security solution or cryptographic primitives. |

Code trigger telemedicine session
A system for creating a unique transaction ID (UTID) securely representing a medical diagnostic transaction between a user/patient and a telemedicine professional is provided. The system includes a first central office database configured to store medical information and profile information for a plurality of users/patients, a second central office database configured to store UTIDs, a memory, and a processor coupled to the memory. The processor is configured to receive test information, initiate generation of a UTID for the new diagnostic transaction, analyze the received test information to determine if the test information indicates a positive or a negative result, transfer the analysis results back to the user/patient's MU, and receive from the MU a request for a telemedicine professional session. |

Discovering context-specific serial health trajectories
Systems and methods are provided for injury characterization including detecting matches of an individual subject's record (such as an athlete's record) with collections of other subjects records, based on serial, longitudinal patterns, for facilitating athlete health and training, preventive and rehabilitation medicine, and risk management in athletics. In an embodiment, time series are formed from information pertaining to successive longitudinal episodes of injury and the circumstances in which the injuries were incurred; calculating time-series K-nearest-neighbor clusters and distances for each such combination; determining the cluster to which a given candidate player injury record is nearest or belongs, and prescribing an injury-risk reduction intervention specific to the plurality of hazards that are characteristic of trajectories that are members of that cluster and that are deemed to be relevant to reducing or mitigating those hazards and thereby are efficacious in preventing subsequent injuries that are prevalent in that trajectory cluster. |

Characterizing heterogeneity with fine-scale population structure
Described are techniques for determining population structure from identity-by-descent (IBD) of individuals. The techniques may be used to predict that an individual belongs to zero, one or more of a number of communities identified within an IBD network. Additional data may be used to annotate the communities with birth location, surname, and ethnicity information. In turn, these data may be used to provide to an individual a prediction of membership to zero, one or more communities, accompanied by a summary of the information annotated to those communities. Ethnicity heterogeneity and age information may be tabulated and provided based on community membership information. |

System and method for creating, querying, and displaying a MIBA master file
A system and method for creating and using a medical imaging bioinformatics annotated (“MIBA”) master file is disclosed. Creating the MIBA master file includes receiving image data, performing a first registration on the image data for obtaining in-slice registered data, and performing a second registration for registering the in-slice registered data to a three-dimensional (3D) model for obtaining source data. Creating also includes extracting voxel data from the source data and storing the voxel data in a MIBA database, receiving selection of a volume of interest, and extracting a portion of the voxel data corresponding to the volume of interest. The MIBA master file is created from the portion of the voxel data, which is stored in the MIBA database. The MIBA system receives a query, extracts data from the MIBA master file in response to the query, and presents the extracted data on an output interface. |

System and method for modeling and subtracting background signals from a melt curve
The present invention relates to methods for the analysis of nucleic acids present in biological samples, and more specifically to normalize a high resolution melt curve to assist in the identification of one or more properties of the nucleic acids. The present invention provides methods and systems that incorporate a background identification algorithm according to invention principles using raw melt curve data to identify reactions that are unrelated actual DNA melt reactions. Furthermore, a web-based application for analyzing experimental data is provided. The raw experimental data obtained from a variety of instruments is processed and analyzed on a server and presented to a user through a user interface (UI). |

Memory module error tracking
In some examples, a memory module includes an error status indicator, an error address register, and error tracking circuitry. The error tracking circuitry may detect that memory data stored at a memory address for the memory module includes an error. In response, and without overwriting the memory data stored at the memory address, the error tracking circuitry may set the error status indicator and store the memory address in the error address register. |
