Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Environmental Policy and Governance, EarlyView.ABSTRACT Global sustainability policy demands coordination among domain‐specific policies, yet a major challenge persists in policy monitoring and reporting, where various, often uncoordinated indicator initiatives exist. To address this challenge, we apply a network approach to investigate linkages between the indicators of the Sustainable Development

Environmental Policy and Governance, EarlyView.ABSTRACT Nature‐based solutions (NBS) for climate adaptation encompass a range of approaches that work with nature to increase resilience to climate change while providing ecological, economic and social co‐benefits. These solutions have frequently been put forward for application in urban contexts, such as the creation of urban forests, but can ...

FlexMat, EarlyView.A soft electrochemical actuator using a hierarchically structured polypyrrole membrane with coral‐like hollow vesicles achieves stable performance at −24°C. The unique architecture ensures continuous conductivity and rapid ion diffusion, resulting in large strain, low energy consumption, and high coulombic efficiency under subzero conditions. This work

Coherent Forecasting of Realized Volatility
Journal of Forecasting, EarlyView.ABSTRACT The QLIKE loss function is the stylized favorite of the literature on volatility forecasting when it comes to out‐of‐sample evaluation and the state of the art model for realized volatility (RV) forecasting is the HAR model, which minimizes the squared error loss for in‐sample estimation of the parameters.

Understanding pre‐eclampsia and fetal growth restriction at high altitude: A narrative review
International Journal of Gynecology &Obstetrics, EarlyView.Abstract Pre‐eclampsia (PE) and fetal growth restriction (FGR) are among the leading causes of maternal and perinatal morbidity and mortality worldwide. Both conditions are more frequent and severe at high altitudes due to physiological changes in oxygen availability and vascular adaptation.

Joint Estimation and Bandwidth Selection in Partially Parametric Models
Journal of Applied Econometrics, EarlyView.ABSTRACT We propose a single‐step approach to estimating a model with both a known nonlinear parametric component and an unknown nonparametric component. We study the large sample behavior of a simultaneous optimization routine that estimates both the parameter vector of the parametric component and the bandwidth vector used to smooth the unknown ...
