Summary: This article presents a systematic review of the application of machine learning algorithms in multiple sclerosis (MS). The study identifies four main applications of ML in MS, including classifying MS subtypes, distinguishing patients from healthy controls, predicting progression and response to therapeutic interventions, and other applications. The results show that ML algorithms can provide great support for healthcare professionals in clinical settings and MS research.

Summary: Correctly defining and grouping electrical feeders is crucial for electrical system operators. This study compares the application of two clustering techniques, K-means and hierarchical agglomerative clustering, using real data from the east region of Paraguay. The results show that the K-means algorithm with the seasonal feature data sets performs the best in terms of validation index scores.

Summary: This paper introduces a data set containing meteorological data and electricity consumption information in Alto Parana, Paraguay. The meteorological data was collected at Guarani Airport in Alto Parana every three hours, including temperature, relative humidity, wind speed, and atmospheric pressure. The electricity consumption data set includes records from 115 feeders in the Alto Paranaregion provided by the National Electricity Administration (ANDE). Analyzing this data can provide insights into energy consumption in the area.

Summary: The third data release of the Gaia mission includes a wide range of new data products, such as an expanded radial velocity survey and extensive astrophysical characterisation. This release provides unprecedented quantity, quality, and variety of source astrophysical data, including spectrophotometry, radial velocities, variables, and astrophysical parameters. It will greatly enhance the potential of Gaia's astrometric, photometric, and radial velocity surveys.

Summary: This study uses the Gaia DR3 set of UCD candidates to investigate the global properties of the set. The study characterizes the UCDs in binary systems and identifies low-mass members of nearby young associations, star-forming regions, and clusters. The study also analyzes the variability properties of the UCDs. The findings provide valuable information for further studies on the faint end of the main sequence and the stellar-substellar transition.

Summary: From an engineering perspective, non-linear systems are crucial for control systems as all systems have a non-linear state. However, the identification of non-linear systems using unknown models is challenging and cannot be applied to large-scale systems. This research proposes a non-linear model of system identification for large-scale systems, considering bilinear and Volterra systems. The novel algorithm SAPeSO is introduced to accurately capture system characteristics and minimize output variation. The effectiveness of the proposed work is compared to existing methods, showing better performance in terms of various error measures.

Summary: Predicting the magnitude of earthquakes is crucial yet complex. Preprocessing using attribute selection techniques helps alleviate this complexity. This study extensively compares 47 years of earthquake data from the Northern California Earthquake Data Center, applying various feature selection algorithms. The results show that by reducing the number of attributes by 80%, metrics of the original data improve significantly, indicating the promising use of attribute selection in this type of problem.
