The Internet of things (IoT) accommodates lightweight sensor/actuator devices with limited resources; hence, more efficient methods for known challenges are sought after. Message queue telemetry transport (MQTT) is a publish/subscribe-based protocol that allows resource-efficient communication among clients, so-called brokers, and servers. However, it lacks viable security features beyond username/password checks, yet transport-layer (TLS/HTTPS) not constrained devices. MQTT also mutual...

Blockchain is a public ledger without central authority. Immutable and inalterable data blocks prove reliability security which are the deficiencies of current Internet things (IoT) devices. IoT devices hardware constrained have specific functions but create large network to gather different data. Because issues devices, industrial use limited. Generally, secure transaction storage main concerns over in order solve problem various solutions being tested. However, decentralized structure like...

Semisupervised learning is a type of machine technique that constructs classifier by from small collection labeled samples and large unlabeled ones. Although some progress has been made in this research area, the existing semisupervised methods provide nominal classification task. However, for ordinal yet to be explored. To bridge gap, study combines two concepts ?semisupervised learning? "ordinal classification" categorical class labels first time introduces new concept "semisupervised...

Background: Chronic lymphocytic leukemia (CLL) is the most common adult leukemia. Approximately 2% of patients with CLL develop immune thrombocytopenic purpura (ITP) during course disease. When resistant to steroids, this constitutes as indication for treatment CLL. Here we report a patient refractory ITP secondary successfully treated venetoclax. Aims: To present an interesting case related novel agent Methods: Patient data was taken from herself and hospital records. Informed consent...

Internet of things (IoT) allows devices with resource constraints such as low processing capability and power consumption to connect a network collect, store share data from these devices. The aim this study is report the performance multi-protocol gateway having various communication technologies for IoT applications. For purpose, designed using different wireless ZigBee, Wi-Fi, Bluetooth energy (BLE). While ESP32 S-WROOM preferred device, Raspberry Pi 4 used gateway. Data sent via Wi-Fi...
