The prediction of climate has been a long-standing problem in contemporary science. One of the reasons stems from a gap in the ability to obtain 3D mapping of clouds, especially shallow scattered clouds. These clouds are strongly affected by mixing processes with their surroundings, rendering their internal volumetric structure highly heterogeneous. These heterogeneous clouds modulate the incoming solar energy and the outgoing long-wave radiation, thereby having a crucial role in the climate system. However, their 3D internal mapping is a major challenge. Here, we combine machine learning and space engineering to enable, for the first time, 3D mapping of scatterers in clouds. We employ ten nano-satellites in formation to simultaneously view the same clouds per scene from different angles and recover the 3D internal structure of shallow scattered clouds, from which we derive statistics, including uncertainty. We demonstrate this on real-world data. The results provide key features for predicting precipitation and renewable energy.

A poor charge transfer (CT) characteristic between FTiOPc and axial ligand C is observed due to the attraction of the C-F bonds to the electron cloud. In addition, the CT characteristic can be effectively improved by peripheral substitution of H-atoms or tetra--butyl groups, and superior one-/two-photon absorption properties can also be achieved owing to the σ-π hyperconjugation effect in tetra--butyl groups.

Machine learning techniques have emerged as a promising tool for efficient cache management, helping optimize cache performance and fortify against security threats. The range of machine learning is vast, from reinforcement learning-based cache replacement policies to Long Short-Term Memory (LSTM) models predicting content characteristics for caching decisions. Diverse techniques such as imitation learning, reinforcement learning, and neural networks are extensively useful in cache-based attack detection, dynamic cache management, and content caching in edge networks.

Background: Interpectoral and pectoserratus plane blocks are fascial plane blocks that are used during anterolateral superficial chest wall surgery. However, the true analgesic efficacy of these blocks in oncological breast surgery is unclear because of the diversity of breast-surgery procedures. The primary hypothesis of this study was that these blocks reduce the incidence of acute pain.
