Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Exploring clean energy alternatives to fossil fuels has become a major research focus worldwide. Wind energy is regarded as one of the most promising renewable energy sources due to its clean and sustainable nature. However, wake interactions among turbines significantly reduce power conversion efficiency, making wind farm layout optimization (

Well‐being decline during adolescence: school transition as a predominant driver beyond age progression

Journal of Child Psychology and Psychiatry, EarlyView.
Background The transition from primary‐to‐secondary school significantly impacts students' well‐being. However, existing research provides limited insight into the long‐term impact of school transition on well‐being, and no studies have disentangled age‐related changes from transition‐specific effects.

The worldwide burden of skin diseases: Lessons from the Global Burden of Disease data

Journal of the European Academy of Dermatology and Venereology, EarlyView.
Skin diseases are a major public health concern worldwide, causing significant personal, economic and social burdens. The Global Burden of Disease (GBD) initiative provides valuable insights but underestimates the burden of skin diseases, emphasizing the urgent need for improved data collection and global collaboration among stakeholders.

Chain‐Length Regulation by WzzE Is Necessary for, but Genetically Separable From, Cyclic Enterobacterial Common Antigen Synthesis

Molecular Microbiology, EarlyView.
Here, we demonstrate that polysaccharide chain length regulation plays a distinct role in enabling formation of a cyclic molecule important for the bacterial cell surface. However, this function is necessary, but not sufficient for the cyclic molecule's biosynthesis.
