Abstract: A first spectrum access system (SAS) instance receives a message (such as a heartbeat message) including an identifier of a first base station that is not registered with the first SAS instance. The first SAS instance accesses a database that is shared with a second SAS instance and periodically synchronized with the second SAS instance. The first SAS instance provides an SAS service that was previously established between the first base station and the second SAS instance in response to the database including a record generated by the second SAS instance for the first base station. The first base station registers to provide connectivity in a shared spectrum using the SAS service provided by the second SAS instance. The first base station transmits the message to the first SAS instance including an identifier of the first base station in response to the second SAS instance becoming unavailable.

Abstract: According to one embodiment, a memory system includes a buffer, a nonvolatile memory and a controller. The buffer is capable of storing packets up to a first upper limit number. The controller generates a packet related to access to the nonvolatile memory and stores the packet in the buffer. The controller classifies the packets into packets of a first type and packets of a second type. The number of packets of the second type allowed to be stored in the buffer is limited to a second upper limit number smaller than the first upper limit number. When the number of packets of the second type stored in the buffer is the second upper limit number or larger, the controller does not generate a second packet of the second type or does not store the second packet in the buffer.

Abstract: A Ransomware Activity Detection System (RADS) characterizes historic read/write IO activity on a storage volume, and also characterizes historic data characteristics of the storage volume, such as the percentage reducibility of the data held in the storage volume. The RADS monitors the storage volume to identify differences between current read/write IO activity and historic read/write IO activity, as well as difference between current data characteristics of the storage volume and historic data characteristics of the storage volume. When the RADS detects a significant difference in read/write IO activity on a storage volume, that is coupled with a significant changes to the data characteristics of the storage volume, the RADS protects the storage volume and generates an alert of the possible occurrence of a ransomware attack. Protection may occur prior in connection with any bulk read operation to proactively protect storage volumes against ransomware attacks.

Abstract: Amperometric gas sensors have unwanted signals that are avoided by using two working electrodes, each having a resistor between the electrode and the current sensing circuit. The resistor has a value of more than 10% of the Faradaic resistor of the electrode. Two different resistors in parallel are switched in and out. The lower value resistor provides fast response for leak detection and safety. A higher value resistor is used for accurate information. The lower value resistor is switched in periodically for diagnostics. Machine-learning uses the periodic switching for determining offset as a function of temperature and humidity.

Abstract: The presently disclosed concepts relate to improved techniques for critical mineral extraction, purification, precipitation, ion exchange, and metal production using a solid electrolyte membrane. By using a solid electrolyte embedded in a matrix, alkali metal (such as lithium) can be more effectively separated from feed solutions. Additionally, energy used to initially extract critical minerals from a feed solution may be stored as electrochemical energy, which in turn, may be discharged when critical minerals are depleted from the electrode. This discharged energy may therefore be reclaimed and reused to extract additional critical minerals.

Abstract: Lightweight mechanisms provide a way to assert provenance when live streaming media content and establish provenance upon playback. For example, a provenance claim generator generates a key pair including a live-stream private key and live-stream public key. The claim generator signs, with a long-term private key reliably associated with a sender, manifest metadata including the live-stream public key, thereby producing a manifest signature. During live streaming, the claim generator signs respective portions of media content with the live-stream private key, producing portion signatures for the respective portions. A provenance claim validator receives the manifest signature and manifest metadata. The claim validator verifies the manifest metadata using a long-term public key (reliably associated with the sender) and the manifest signature.
