Ilford FP4 @ ISO 64 **English:** This black-and-white image shows a solitary young tree standing in an open area, possibly a park or garden. The tree is slender with sparse branches and few leaves, indicating it might be early spring or late autumn. The background features a tall residential building, contrasting the natural element of the tree with the urban environment. The ground around the tree is covered with grass, and the overall atmosphere is calm and serene. **Chinese:** 这张黑白照片展示了一棵孤…
Ilford FP4 @ ISO 64 **English:** This black-and-white photograph depicts a young tree planted in a rural landscape. The tree is centrally located and appears to be supported by a small mound of soil at its base. The surrounding area is grassy with patches of bare earth. In the background, there are more young trees, suggesting a plantation or orchard setting. The terrain is slightly hilly, and the overall scene conveys a sense of early growth and cultivation. **Chinese:** 这张黑白照片描绘了一棵种植在农村景观中的…
Ilford FP4 @ ISO 64 **English:** This black-and-white photograph depicts a natural landscape with various trees and shrubs. The foreground features a prominent pine tree with long needles and a distinctive shape. The background includes a mix of other trees and vegetation, creating a dense and lush environment. The lighting suggests it might be a sunny day, with shadows cast on the ground, adding depth to the scene. The overall atmosphere is one of natural beauty and tranquility. **Chinese:**…
Ilford FP4 @ ISO 64 **English alt text:** A black and white photograph of a small branch with a few buds and droplets of water on it. The background is blurred, making the branch the focal point of the image. **Chinese alt text:** 一张黑白照片，展示了一根带有几个花蕾和水滴的小树枝。背景模糊，使树枝成为图像的焦点。

More depressing news as governments swallow propaganda from the nuclear power lobby.
Renewables won't deliver the power currently used, and projected, but nor will nuclear, which also depends on fossil fuels, uses a scarce and diminishing resource, and leaves a toxic legacy for which there is no adequate solution.
The only solution is radical energy descent.

Constraint Maps: Insights and Related Themes
This paper explores recent progress related to constraint maps. Building on the exposition in [14], our goal is to provide a clear and accessible account of some of the more intricate arguments behind the main results in this work. Along the way, we include several new results of independent value. In particular, we give optimal geometric conditions on the target manifold that guarantee a unique continuation result for the projected image map. We also prove that the gradient of a minimizing har…

Well color me surprised. Had no hope Cuomo would lose that one and lost faith in America quite a while ago.
Good job #NYC

Mechanically Reconfigurable GRIN Lens Concept for Focusing and Beamforming Applications
This study presents a prospective concept of a mechanically reconfigurable Gradient Index (GRIN) lens for focusing and beamforming applications. The lens is formed by corrugated layers, each realizing a refractive index profile expressed in a basis of Chebyshev polynomials. The focal point position is controlled by shifting the GRIN lens layers. A geometrical optics-based approach is implemented for the three scenarios of focusing at varying focal distance. The geometrical optics results are va…

Optimal Design of Experiment for Electrochemical Parameter Identification of Li-ion Battery via Deep Reinforcement Learning
Accurate parameter estimation in electrochemical battery models is essential for monitoring and assessing the performance of lithium-ion batteries (LiBs). This paper presents a novel approach that combines deep reinforcement learning (DRL) with an optimal experimental design (OED) framework to identify key electrochemical parameters of LiB cell models. The proposed method utilizes the twin delayed deep deterministic policy gradient (TD3) algorithm to optimize input excitation, thereby increasin…

Probing multi-band variability and mode switching in the candidate transitional millisecond pulsar 3FGL J1544.6-1125
We present the most extensive high-time resolution multi-band campaign to date on the candidate transitional millisecond pulsar (tMSP) 3FGL J1544.6-1125 in the sub-luminous disk state, with coordinated observations from the radio to the X-ray band. While XMM-Newton and NuSTAR X-ray light curves exhibit the characteristic high- and low-mode bimodality, the source faintness prevents firm evidence for similar bimodality in the ultraviolet and near-infrared light curves, presented here for the firs…

Art of the Lie

The image is a political cartoon featuring a caricature of a man with exaggerated facial features, wearing a dark blue suit and a red tie. The man has a large, prominent nose and is depicted with a confident expression, with his arms outstretched. He is standing against a gradient blue background. In the speech bubble above his head, he proclaims, "I'M THE BEST DEAL MAKER!" Below him, in a yellow box, there is a contrasting statement: "NOT MUCH OF A DEAL KEEPER, THOUGH." The cartoonist's signa…
