Summary: This study investigates the gene flow between different geographic types of the plant species Rumex hastatulus, revealing that hybrids readily form and survive multiple backcross generations in the field. The study also suggests that the neo-sex chromosomes play a role in reproductive isolation between different geographic types.

Summary: This study investigated the genomic mechanisms of coevolution between nonmodel mammals and their parasitic roundworms. The research revealed that the parasitic roundworms did not phylogenetically coevolve with their hosts but showed coevolution in specific proteins during protein interaction. Additionally, roundworms in both pandas exhibited unique genetic features related to metallopeptidase genes and fast larval development.

Summary: The study compares associations between childhood maltreatment and adult physiological dysregulation using multiple dimension reduction approaches and measures of maltreatment. The significance and magnitude of effects varied with different maltreatment and physiological dysregulation measures. Further review of the methods used to study adult health conditions and their relation to childhood maltreatment is needed.

Summary: Wear of the secondary circuit in welding guns can lead to quality problems and production stoppages. This study develops a virtual sensor to estimate the resistance of the welding arm and an anomaly detection method based on the Mahalanobis distance. An integral system for detecting secondary wear of welding guns in real production lines is proposed.

Summary: Many areas in the world lack sufficient soil data, leading to ineffective soil-related studies and inadequate soil management strategies. This paper demonstrates how to find "homosoils", which are geographically distant but share similar soil-forming factors, in order to obtain new soil data for a study area. By clustering the study area into homogeneous areas and identifying a homosoil for each area using distance metrics, this approach provides a solution to the problem of sparse soil data. The concept of homosoils shows promise for future applications such as transferring soil models and agronomic experimental results between areas.

Summary: This study evaluates a scaled-down bridge model under pedestrian motions for damage monitoring using piezo sensors under operational modal analysis (OMA). The results show that strain-based damage sensitive features are superior to displacement-based ones, especially for incipient damage states.

Summary: The number of space debris has increased due to the rise in space missions, which necessitates collision avoidance maneuvers for the safety of operating satellites. This study focuses on fuel-optimal collision avoidance maneuvers considering the effects of uncertainty. Two formulations, convex optimization and non-convex optimization, are presented and compared. The impact of optimization algorithms and discretization points on optimal Delta v and computational speed is also discussed.

Summary: This paper proposes a novel hybrid method called Weighted Turbulence, which combines dynamic network and weighted Mahalanobis distance to measure the overall systemic risk level of the international energy markets system. The proposed method accurately detects the spikes of systemic risk in international energy markets and eliminates the negative impact of non-systematic markets, showing practical and theoretical significance.

Summary: The most common metrics for collision risk assessment include probability of collision, miss distance in Mahalanobis space, and confidence intervals. This study reveals the intimate connection among these risk indexes when a suitable distance is defined. The minimum Mahalanobis distance between the hard-body circle and the combined position covariance is proposed as an alternative metric. It provides an upper bound to the collision probability and can be used to scale the covariance matrix to determine the largest confidence interval supporting a noncollision event. Analytical boundaries on the probability of miss detection and false alarms can be computed when this metric is adopted as an actionable threshold.

Summary: This paper proposes a method based on DPGMM for real-time monitoring of wind turbine performance degradation. The method constructs a baseline performance model using normal operational data and identifies the contour of the main power band using confidence ellipses of Gaussian components. In the monitoring phase, Mahalanobis distance is used to determine whether new monitoring data indicates performance degradation, triggering a degradation alarm.

Summary: This study used statistical distances to analyze hyperspectral images for the classification of neutrophils from CML and healthy blood samples. The Euclidean distance method was found to be more sensitive in detecting CML neutrophils, while the Mahalanobis distance method was better at detecting healthy neutrophils and distinguishing CML neutrophils from healthy neutrophils.
