Modeling the chemical composition of a biological cell wall
Techniques are described for determining the strain on a cell wall using two models: 1) a short timescale model, describing the relationship between physical properties assumed to be fixed and 2) a long timescale model, describing the dynamic chemical composition of a cell wall. Short term modeling of the physical properties in a cell wall is used to properly understand how physical factors such as osmotic pressure affects the strain on the cell wall, which is in turn used to identify conditions under which a cell wall will cease to function properly or lyse entirely. Although temporally the physical properties which cause cell walls to underperform/lyse can be evaluated under a short time frame, the chemical properties that lead to the physical properties which cause that behavior themselves change over much longer timescales, in a relative sense. |

Methods and apparatus for radio frequency sensing in diverse environments
A system may sense the contents of a closed container, by analyzing a wireless signal that reflects from an RFID tag on the outside of the container. The frequency response of the tag's antenna may be affected by the relative permittivity of the contents and by the tag's environment. The frequency response may be measured in a line-of-sight environment and in a multipath environment. Channel estimates may be calculated, based on the measurements. Channel ratios may be calculated by dividing line-of-sight channel estimates by multipath channel estimates. The resulting channel ratios may be fed into a variational autoencoder, which in turn generates synthetic data that contains information about multipath environments but not the contents. The output of the variational autoencoder may be converted into synthetic channel estimates, which may in turn be employed for anomaly detection, or to train a classifier to classify contents of the container. |

Predicting and deleting idle remote sessions in a distributed file system
Techniques are provided for predicting and deleting idle remote sessions in a distributed file system. In an example, a server that serves a plurality of server message block (SMB) sessions analyzes with linear regression techniques those sessions to determine which sessions will become idle. In some examples, the server can then proactively close a SMB session that it predicts that an administrator would choose to close after a given idle period of time, or recommend to an administrator that the SMB session can be closed. |

Multiple accumulate busses in a systolic array
Systems and methods are provided to enable parallelized multiply-accumulate operations in a systolic array. Each column of the systolic array can include multiple busses enabling independent transmission of input partial sums along the respective bus. Each processing element of a given columnar bus can receive an input partial sum from a prior element of the given columnar bus, and perform arithmetic operations on the input partial sum. Each processing element can generate an output partial sum based on the arithmetic operations, provide the output partial sum to a next processing element of the given columnar bus, without the output partial sum being processed by a processing element of the column located between the two processing elements that uses a different columnar bus. Use of columnar busses can enable parallelization to increase speed or enable increased latency at individual processing elements. |

Multiple busses interleaved in a systolic array
Systems and methods are provided to enable parallelized multiply-accumulate operations in a systolic array. Each row of the systolic array can include multiple busses enabling independent transmission of inputs along the respective bus. Each processing element of a given row-oriented bus can receive an input from a prior element of the given row-oriented bus, and perform arithmetic operations on the input. Each processing element can generate an output partial sum based on the arithmetic operations, provide the input to a next processing element of the given row-oriented bus, without the input being processed by a processing element of the row located between the two processing elements that uses a different row-oriented bus. Use of row-oriented busses can enable parallelization to increase speed or enable increased latency at individual processing elements. |

Multi-path RDMA transmission
In accordance with implementations of the subject matter described herein, there provides a solution for multi-path RDMA transmission. In the solution, at least one packet is generated based on an RDMA message to be transmitted from a first device to a second device. The first device has an RDMA connection with the second device via a plurality of paths. A first packet in the at least one packet includes a plurality of fields, which include information for transmitting the first packet over a first path of the plurality of paths. The at least one packet is transmitted to the second device over the plurality of paths via an RDMA protocol. The first packet is transmitted over the first path. The multi-path RDMA transmission solution according to the subject matter described herein can efficiently utilize rich network paths while maintaining a low memory footprint in a network interface card. |

Methods and apparatus for using an addressable serial peripheral interface
Devices in an array of devices, coupled to a common SPI bus, are automatically assigned identifiers by an enumeration process. In some embodiments, the devices are coupled together in an enumeration daisy chain. The enumeration function is initiated, e.g., by a controller, with a single SPI transaction. |

Systems and methods for door and dock equipment servicing
A method for monitoring automatic mechanical devices selected from at least one of automatic doors and automatic dock equipment located at a commercial site. The method may include installing, at the commercial site, a plurality of internet-of-things (IoT) monitoring devices. Each of the IoT monitoring devices may include a plurality of connectors corresponding to respective data communication standards, and a wireless transceiver configured to transmit operational information. Electronic communication between each automatic mechanical device and one of the IoT monitoring devices may be established via one of the connectors. A device profile may be assigned for each of the automatic mechanical devices. Each device profiles defines a respective connector and combination of manufacturer and device model. Data reflecting operational events and states of the automatic mechanical devices is received over the connectors, and corresponding operational information relating to the automatic mechanical devices is transmitted for analysis. |
