The spread of infectious diseases such as COVID-19 depends on complex fluid dynamics interactions between pathogens and phases, including individual droplets multiphase clouds. Understanding these is crucial for predicting controlling disease spread. This applies to human animal exhalations, coughs sneezes, well bursting bubbles that create micron-sized in various indoor outdoor environments. By exploring case studies this regard, study examines the emerging field transmission, focusing flows, interfacial turbulence, pathogens, traffic, aerosol ventilation, breathing microenvironments. These results indicate increased ventilation rates local methods can effectively reduce concentration SARS-CoV-2-laden aerosols immediate spaces individuals. In a displacement-ventilated room, both neutral unstable conditions were more effective removing breathed from air, regardless presence test subjects. However, stable may increase risk infection individuals living confined spaces. Thus, findings are useful providing practical guidance managing airborne infections.

In recent years, Digital Twins (DTs) implementation has significantly impacted various sectors like industry, healthcare, engineering, and technology. However, the examination of these areas concerning pandemic management is still in its early stages. To bridge this gap, a systematic literature review was conducted here spanning from 2017 to March 2024, with specific focus on COVID-19-related issues 2020 2024. Employing five-step filtering process, nearly 10,000 articles were initially identified based search strings. Subsequently, 297 publications selected examined across pre-pandemic, pandemic, post-pandemic phases discern emerging patterns, limitations, future research directions. Drawing insights, concept for 'Digital-Twin-based Smart Pandemic City' proposed, aiming ensure contemporary amenities while preparing potential pandemics by leveraging advanced cloud storage blockchain technology secure data aggregation.

This paper comprehensively investigates the performance of various strategies for predicting CO2 levels in school classrooms over different time horizons by using data collected through IoT devices. We gathered Indoor Air Quality (IAQ) from fifteen schools Navarra, Spain between 10 January and 3 April 2022, with measurements taken at 10-min intervals. Three prediction divided into seven models were trained on compared statistical tests. The study confirms that simple methodologies are effective short-term predictions, while Machine Learning (ML)-based perform better longer horizons. Furthermore, this demonstrates feasibility low-cost devices combined ML forecasting, which can help to improve IAQ sensitive environments such as schools.

Drug discovery before the 20th century often focused on single genes, molecules, cells, or organs, failing to capture complexity of biological systems. The emergence protein-protein interaction network studies in 2001 marked a turning point and promoted holistic approach that considers human body as an interconnected system. This is particularly evident study bidirectional interactions between central nervous system (CNS) peripheral which are critical for understanding health disease. Understanding these complex requires integrating multi-scale, heterogeneous data from molecular organ levels, encompassing both omics (e.g., genomics, proteomics, microbiomics) non-omics imaging, clinical phenotypes). Artificial intelligence (AI), multi-modal models, has demonstrated significant potential analyzing CNS-peripheral by processing vast, datasets. Specifically, AI facilitates identification biomarkers, prediction therapeutic targets, simulation drug effects multi-organ systems, thereby paving way novel strategies. review highlights AI's transformative role research, focusing its applications unraveling disease mechanisms, discovering optimizing trials through patient stratification adaptive trial design.

In the post-pandemic context, data-driven design interventions that can endow architectural spaces with mixed-use and open characteristics are adaptable environmentally resilient increasingly important. Ubiquitous semi-public architecture, such as hotel buildings, plays a crucial role in public health emergencies. Many hotels adopt room spatial layouts, integrating diverse daily functions into single tiny space, fostering flexible utilization micro-scale space sharing; however, these also introduce potential risks. This study offers comprehensive evaluation of indoor environmental quality (IEQ) discusses feasible intervention strategies for healthier renovation rehabilitation. Taking Shenzhen case, multi-domain assessment was conducted during COVID-19 quarantine period summer 2022. The examines risks inherent hotel’s guest varying patterns IEQ factors across domains, including volatile organic compound concentrations, physical parameters, heat stress indices. results illustrate change trends chemical, physical, present tested quarantined throughout typical day.
