Patients with microscopic polyangiitis (MPA) and positive myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) may present with various abnormalities in chest computed tomography (CT). This study aimed to identify subphenotypes using latent class analysis (LCA) and to explore the relationship between the subphenotypes and clinical patterns, as well as compare the clinical characteristics of these subphenotypes in patients with MPO-ANCA-positive MPA (MPO-MPA).

MQTT technology is always a first choice regarding how to build a UNS. Readers unfamiliar with MQTT might be curious why it always appears with UNS in IIoT 4.0 solutions. This episode will walk you through why MQTT is the best partner for building UNS. What Is MQTT? Before entering the world of UNS, it is important to have a basic knowledge of MQTT. MQTT (Message Queuing Telemetry Transport) is a lightweight, publish-subscribe-based messaging protocol.

The Modbus protocol is a communication protocol that allows devices to communicate over various types of media, such as serial lines and ethernet. It was developed in 1979 by Modicon, a company that produced Programmable Logic Controllers (PLCs), to enable these devices to communicate with each other. Modbus provides a messaging structure designed to establish master-slave communication between intelligent devices.

In Introduction to MQTT Publish-subscribe Pattern, we learned that we need to initiate a subscription with the server to receive corresponding messages from it. The topic filter specified when subscribing determines which topics the server will forward to us, and the subscription options allow us to customize the forwarding behavior of the server further. In this article, we will focus on exploring the available subscription options in MQTT and their usage.

What Is IoT in the Cloud? The Internet of Things, or IoT, refers to the network of physical devices, vehicles, appliances, and other items embedded with sensors, software, and network connectivity, which enables these objects to connect and exchange data. IoT in the cloud means storing and processing the massive amounts of data generated by these interconnected devices in the cloud, rather than on local servers or in traditional data centers.

Our previous articles of this series explored various methods to safeguard IoT devices from cyberattacks, including encryption, authentication, and security protocols. However, it is crucial to acknowledge that regular updates and maintenance are equally vital to ensure the ongoing security of IoT devices. Moreover, with the increasing migration of systems and services to the cloud, the security of the underlying operating system assumes even greater significance.

In previous articles, we explored authentication and access control mechanisms. Now it's time to shine a light on the crucial role of Transport Layer Security (TLS) in fortifying MQTT communication. This article will focus specifically on TLS and its ability to ensure the integrity, confidentiality, and authenticity of MQTT communication. Concepts ExplainedBefore we start, let's get some key concepts explained.
