Submission Date: 2024-10-31

This collection provides recent developments based on the previous collection: Fuzzy Decision Support Systems for Biomedical Data Analysis.
Biomedical data presents several challenges in data analysis, including high dimensionality, class imbalance and low numbers of samples. Although current research in this field has shown promising results, several research issues still need to be explored. Biomedical data are available in different formats, including numeric, textual reports, signals and images, and the data can be derived from different sources. Biomedical data often suffer from incompleteness, uncertainty and vagueness, which complicates conventional techniques of data mining, ranging from the model, algorithm, system and application. An interesting research aspect is to integrate different data sources in the biomedical data analysis process, which requires exploiting the existing domain knowledge from available sources. There is also a need to explore novel methods in the biomedical research to improve predictive performance along with interpretation of prediction models. The management of uncertainty in decision making problems is a very challenging research issue, because deterministic or probabilistic classical decision approaches quite often do not fit well to real-world decision-making problems. In spite of the existence of many tools to model and manage such an uncertainty, depending on the uncertain situation, some tools may be more suitable than others. Fuzzy sets and its various extensions such as intuitionistic fuzzy sets, neutrosophic set, Pythagorean set, Hesitant set provide a standardized way to solve many real-life problems that involve uncertainty, impreciseness, vagueness, incompleteness, inconsistent, and indeterminacy. A number of new theories have been proposed under these environments and have been applied in multi-criteria decision making, computational intelligence, image processing, medical diagnosis, fault diagnosis, optimization design, and so on. The aims of this Topical Collection are: (1) to present the state-of-the-art research on decision support systems and its application in biomedical data, and (2) to provide a forum for researchers to discuss the latest progress, new research methodologies, and potential research topics.

Special Issue on Earth and Environmental Sciences: Mitigation and Adaptation Strategies in a Multi-Risk Perspective
Submission Date: 2024-11-30

The growing concerns related to climate change and the increasing frequency of significant natural hazard impacts require the identification of adaptation and mitigation strategies. However, most of the time, risk reduction strategies consider one risk at a time and ignore the potential synergies (or conflicts) that these might have with other hazards. For instance, urban greening can be beneficial for both pluvial flooding and heat waves (synergy), and moving building contents to upper flood-safe floors can aggravate seismic risks (conflict). Therefore, each solution should be evaluated within the broad spectrum of multiple hazards in a multi-disciplinary way to promote risk capacity and resilience. This Topical Collection aims to profile a diverse range of mitigation and adaptations approaches within a multi-hazard and multi-risk perspective, including but not limited to structural and non-structural solutions, nature-based solutions, mapping and planning for reducing the impacts of multi-hazards on different exposed assets (e.g., infrastructures, building, population, cultural heritage etc.) with a quantitative evaluation of co-benefits or resolution of potential conflicts.

Special Issue on Earth and Environmental Sciences: Life Cycle Assessment of Processes and Products
Submission Date: 2024-11-30

Life Cycle Assessment (LCA) plays an essential part in estimating the environmental impact of new technologies and methods. LCA is a methodology to analyze and compare various products and technologies considering their environmental effects along the whole life cycle, i.e. from the subtraction of raw materials until the end-of-life of a product. LCA helps to determine which product has the most negligible environmental impact over others by assessing the effects of products and processes throughout their lifecycle.

At an initial stage of a novel technology process, it is fundamental to recognize the environmental burdens. Calculating the effects when assessing a new technology is demanding, as the number of possible results can be enormous. More than two-thirds parts of the final expenses and effects on the environment are based on decisions that are made in the initial development phase of the technology. For this reason, it is extremely important to study technologies' environmental effects even before they are put into practice.

In this collection, we welcome articles focusing on the life cycle assessment of various products or processes. It can be a single evaluation or a comparison of different methods. The frame of the research can be any version, e.g., gate-to-gate, cradle-to-gate or cradle-to-grave analyses. We are also open to new research directions and/or combining LCA with economic and energy factors.

Special Issue on Interdisciplinary: Advanced Method for Signals Processing in Earth and Environmental Sciences
Submission Date: 2025-01-31

Adequate signal processing (including 2D, i.e., images, and multidimensional signals in the term) is of paramount importance in Earth & Environmental Sciences. Think e.g., of the study of crustal kinematics using GNSS time series, of the various remote sensing techniques and applications, of the acquisition of seismic data in real time or for geophysical prospecting, of the acquisition and analysis of time series in oceanography, of the detection of trends in atmospheric time series. In some cases, the signals can be characterized by the absence of data for more or less prolonged periods, by significant variations in the observation conditions and therefore uncertainties or are sometimes reconstructed on the basis of more or less stringent hypotheses (an example is the reconstruction of the conditions of thermohaline oceanic circulation starting from paleontological data). This Collection is devoted to advanced methods of signal processing in Earth and Environmental Sciences. Papers dedicated to both theoretical and technological aspects of signal processing (provided they are consistent with the topic) and to the applications of advanced methods, as well as simulation, are welcome. Papers focused on deep learning in signal processing, aimed e.g., at data filtering or reconstructing missing segments of time series, are particularly encouraged. Manuscripts describing the acquisition of information of geophysical/environmental interest from disturbances of radio/TV/phone/… signals are also encouraged. Although not strictly required, it is strongly encouraged that any codes developed be made available to the reader (e.g., in Harvard Dataverse or Zenodo).

Special Issue on Engineering: Recent Advancements in Waste Recovery Technologies
Submission Date: 2025-01-31

Among the various waste heat recovery technologies, supercritical CO2 power cycle, and organic Rankine cycles are considered one of the promising cycles for waste heat recovery in industry. Given the significance of this subject, you are invited to contribute a research article to this collection. The contributions may include, but are not limited to, supercritical CO2 power cycles, organic Rankine cycles, design and analysis of heat exchangers, design and analysis of expansion machines, and thermal storages.

Special Issue on Earth and Environmental Sciences: Advancements in Monitoring Soil Water and Plant Conditions in a Changing Climate
Submission Date: 2025-01-31

Soil water and plant systems are interconnected, and their interactions play a crucial role in the climate system. Monitoring these interactions is important for understanding and predicting the impacts of climate change on soil and plant systems and for developing sustainable land and soil management practices. Monitoring soil water and plant conditions in a changing climate is critical because soil moisture is essential for photosynthesis, it serves as a carrier of nutrients and minerals for plant growth, and in general helps keep soil ecosystems healthy. Soil physical, chemical, and biological properties influence the storage of soil moisture, plant development, and consequently the climate system, which properties play a crucial role in controlling factors such as evaporation, transpiration, or soil temperature. Changes in land use or other soil parameters (e.g. tillage) can accelerate or slow climate change-related effects on the soil-plant-water system.

This Topical Collection focuses on longer term monitoring on any part or the entire soil-plant-water system, particularly advancements in instruments or the use of current technologies and information, such as remote sensing. This interdisciplinary Collection invites papers in the topics on recent techniques, such as new instruments or remote sensing data on soil moisture monitoring; plant growth, development, or physiological monitoring; climate change-related studies; or the effects of soil management systems on soil-plant-water systems.

Special Issue on Earth and Environmental Sciences: Environmental Tracers in Water Resources Management
Submission Date: 2025-02-24

 Environmental tracers are defined as geogenic (natural to the Earth) or anthropogenic (human-created) isotopes, elements, or compounds that are widely distributed in the near-surface environment of the earth, such that variations in their abundances can be used to infer environmental processes. An ideal tracer of water flow is one that is soluble, mobile, relatively unreactive, and easily measured. However, while tracers that behave conservatively (that is, do not cling to subsurface materials nor undergo chemical change) in the environment yield information on water sources or transport processes, tracers that readily undergo chemical reactions can be used to determine hydro-chemical conditions in aquifers and reaction pathways. Several environmental tracers also provide information on the timescales of subsurface processes. These include radioactive tracers, which decay at a known rate; radiogenic tracers, which are produced and accumulate in the subsurface; and event markers, which are neither produced nor consumed in the subsurface but have a variable and well-known history as to when they entered the water system. These can be used for various surface water, ground water, environmental and hydrometeorological studies and help in solving the difficulties involved in hydrological evaluations.

Submission Date: 2025-03-10

In the last decades, the environment and all the ecosystems are progressively threatened by pollution, evidencing a worldwide problem of great concern that needs urgent solutions.

Different pollutants are released every day in water bodies, and some of these chemicals are endocrine disruptors, carcinogenic, mutagenic. Accordingly, Contaminants of Emerging Concern (CECs), and textile dyes, are particularly dangerous categories due to their toxicological impact on human and environmental health, even in traces, although the risks they pose are still not fully understood. For these reasons, their removal is necessary. Thus, researchers are working hardly for finding solutions to ensure the safety of all ecosystems. The innovative tendency represented by the use of wastes and by-products as adsorbents materials to treat water from pollutants is increasing in the last years, according to greener technologies.

Besides, natural-based polymeric materials are still widely used for the purpose. Among remediation strategies, the adsorption, even when in synergy with the Advanced Oxidation Processes (AOPs), is widely studied.

This Topical Collection aims to offer a background about these useful materials and approaches, proposing the sustainable management, the efficient use of natural resources as dictated by Bioeconomic principles, and the reduction of wastes through recycling and upcycling.
