Reducing latency in OFDMA using front ends with adaptive linearity
Embodiments herein describe assigning different linearity operating points of a front end of a radio to groups of user devices when transmitting data using OFDMA. That is, when transmitting a PPDU to a first group of user devices, an access point (AP) may set the front end of the radio to a lower linearity operating point than when transmitting a PPDU to a second group of user devices. Using a higher linearity operating point can increase the data rate used to transmit the PPDU—e.g., the AP can use a higher modulation coding scheme (MCS). This can reduce the time the PPDUs have to wait in a queue before being transmitted. |

Systems and methods for integrating neural network image analyses into medical image viewing applications
Systems for delivering one or more studies, where each of the one or more studies has a series of digital images associated with only one person and generated by an imaging modality, is disclosed. The systems include a syncing application that is configured to execute within a local area network and that is in data communication with imaging modalities and/or computing devices configured to display images generated by each of the imaging modalities. The systems also include a server adapted to be external to the local area network and in data communication with the syncing application and a client-side viewing application installed on one or more of the computing devices. The client-side viewing application is configured to acquire the studies, including unrendered data representative of the digital images of the series, locally render the unrendered data, and enable a user to manipulate the digital images. |

System and method for longitudinal non-conforming medical data records
A computer-assisted method including obtaining healthcare records from multiple different data sources that each provide information regarding a corresponding type of healthcare events, identifying healthcare records from the multiple different data sources that are for a healthcare event associated with a particular individual and that occurred during a particular period of time, and generating a composite record for the particular individual for the particular period of time, and storing the composite record in a database of composite records. The composite record include an identifier for the particular individual, a pharmaceutical transactions array, where each entry in the pharmaceutical transactions array represents a pharmaceutical transaction that occurred during the particular period of time, and a medical visit array, where each entry in the medical visit array represents a medical visit that occurred during the particular period of time. |

Analysis of fragmentation patterns of cell-free DNA
Factors affecting the fragmentation pattern of cell-free DNA (e.g., plasma DNA) and the applications, including those in molecular diagnostics, of the analysis of cell-free DNA fragmentation patterns are described. Various applications can use a property of a fragmentation pattern to determine a proportional contribution of a particular tissue type, to determine a genotype of a particular tissue type (e.g., fetal tissue in a maternal sample or tumor tissue in a sample from a cancer patient), and/or to identify preferred ending positions for a particular tissue type, which may then be used to determine a proportional contribution of a particular tissue type. |

Method for writing in a non-volatile memory according to the ageing of the memory cells and corresponding integrated circuit
A semiconductor well of a non-volatile memory houses memory cells. The memory cells each have a floating gate and a control gate. Erasing of the memory cells includes biasing the semiconductor well with a first erase voltage having an absolute value greater than a breakdown voltage level of bipolar junctions of a control gate switching circuit of the memory. An absolute value of the first erase voltage is based on a comparison of a value of an indication of wear of the memory cells to a wear threshold value. |

Identify the programming mode of memory cells during reading of the memory cells
Systems, methods and apparatus to determine a programming mode of a set of memory cells that store an indicator of the programming mode. In response to a command to read the memory cells in a memory device, a first read voltage is applied to the memory cells to identify a first subset of the memory cells that become conductive under the first read voltage. The determination of the first subset is configured as an operation common to different programming modes. Based on whether the first subset of the memory cell includes one or more predefined memory cells, the memory device determines a programming mode of memory cells. Once the programming mode is identified from the common operation, the memory device can further execute the command to determine a data item stored, via the programming mode, in the memory cells. |

Apparatuses and methods including memory and operation of same
Disclosed herein is a memory cell. The memory cell may act both as a combined selector device and memory element. The memory cell may be programmed by applying write pulses having different polarities. Different polarities of the write pulses may program different logic states into the memory cell. The memory cell may be read by read pulses all having the same polarity. The logic state of the memory cell may be detected by observing different threshold voltages when the read pulses are applied. The different threshold voltages may be responsive to the different polarities of the write pulses. |
