Data assimilation and multisource decision-making in systems biology based on unobtrusive Internet-of-Things devices

Abstract

Biological and medical diagnoses depend on high-quality measurements. A wearable device based on Internet of Things (IoT) must be unobtrusive to the human body to encourage users to accept continuous monitoring. However, unobtrusive IoT devices are usually of low quality and unreliable because of the limitation of technology progress that has slowed down at high peak. Therefore, advanced inference techniques must be developed to address the limitations of IoT devices. This review proposes that IoT technology in biological and medical applications should be based on a new data assimilation process that fuses multiple data scales from several sources to provide diagnoses. Moreover, the required technologies are ready to support the desired disease diagnosis levels, such as hypothesis test, multiple evidence fusion, machine learning, data assimilation, and systems biology. Furthermore, cross-disciplinary integration has emerged with advancements in IoT. For example, the multiscale modeling of systems biology from proteins and cells to organs integrates current developments in biology, medicine, mathematics, engineering, artificial intelligence, and semiconductor technologies. Based on the monitoring objectives of IoT devices, researchers have gradually developed ambulant, wearable, noninvasive, unobtrusive, low-cost, and pervasive monitoring devices with data assimilation methods that can overcome the limitations of devices in terms of quality measurement. In the future, the novel features of data assimilation in systems biology and ubiquitous sensory development can describe patients’ physical conditions based on few but long-term measurements.

Avaliação do uso de tecnologias vestíveis nos músculos masseter e temporal: um protocolo de revisão de escopo

“…Assim, a assistência informatizada ideal deve avaliar a significância estatística das conclusões e ampliar o escopo de especialistas humanos para realizar investigações demoradas e de grande quantidade, bem como não imitar os processos humanos. Os avanços tecnológicos melhoraram as inferências para trás e para frente para fornecer novas evidências para o julgamento de qualidade por especialistas humanos 13 . Muito além do diagnóstico, o papel dos dispositivos vestíveis no paradigma da p-health, ou seja, participação, prevenção, previsão, preempção, pervasiva e personalizada, tem sido destacado 14 .…”

Evaluating the use of wearables in the masseter and temporal muscles: a scoping review protocol

“…Thus, the ideal computerized assistance must evaluate the statistical significance of the findings and expand the scope of human experts to perform time-consuming and large-quantity investigations, as well as not mimic human processes. Technological advances have improved backward and forward inference to provide new evidence for quality judgment by human experts 13 .…”

Optimizing Ambiance: Intelligent RGB Lighting Control in Structures Using Fuzzy Logic

“…This type of logging implies that the data are stored for a certain period of time; in case the system cannot reconnect to the network, it will retain the data for 12 record days [60]. These datasets are stored in a non-volatile memory, ensuring that even power failures can maintain the stored data [60].…”
