Now this was a gorgeous cycling loop. Temperature was around freezing but luckily just few wind. As you see, the weather was ace. Clouds and fog stayed in the north 🌞
Also tried Knee warmers, which was just right! A very good buy!
I just need a solution against freezing toes. @… ,I bought neoprene toe warmer! The shoes are just a bit tight then, …

This image captures a serene winter scene of a partially frozen lake under a clear, bright blue sky. The sun is shining, casting a soft light over the landscape and creating a peaceful atmosphere. The surface of the lake is mostly frozen, with patches of ice and small areas of open water reflecting the sunlight. In the foreground, there is a grassy area with dry, brownish vegetation, leading to a wooden walkway that extends along the shoreline. The walkway adds a touch of human presence to the…
This image features a self-portrait of a cyclist taking a break during what appears to be a winter ride. The cyclist is wearing a helmet, sunglasses, and a black face mask, likely for warmth and protection against the cold. They are giving a thumbs-up, indicating a positive and enjoyable experience. The background showcases a beautiful outdoor setting with a green, open field that stretches out into the distance. The field is bordered by a line of evergreen trees, adding a touch of natural bea…

Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs
Globular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, such as horizontal branch (HB), extreme HB, and blue stragglers, remains poorly constrained. These stars are often underrepresented or entirely excluded from stellar population models, despite their dominant contribution to the ultraviolet (UV) flux. Their presence can bias age estimates by mimicking the spectral signat…

A nodally bound-preserving composite discontinuous Galerkin method on polytopic meshes
We introduce a nodally bound-preserving Galerkin method for second-order elliptic problems on general polygonal/polyhedral, henceforth collectively termed as \emph{polytopic}, meshes. Starting from an interior penalty discontinuous Galerkin (DG) formulation posed on a polytopic mesh, the method enforces preservation of \emph{a priori} prescribed upper and lower bounds for the numerical solution at an arbitrary number of user-defined points \emph{within} each polytopic element. This is achieved …
