Pre‐hospital and In‐hospital Delays After Onset of Acute Ischemic Stroke—A Hospital‐based Study in Southern Taiwan

Kaohsiung Journal of Medical Sciences, 2007
The biggest hurdle for early hospital presentation is the narrow therapeutic window after stroke. The aims of our study were to investigate the time lags and the factors causing pre‐hospital and emergency department (ED) delay during acute ischemic ...

Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

Static and Dynamic Behavior of Novel Y‐Shaped Sandwich Beams Subjected to Compressive Loadings: Integration of Supervised Learning and Experimentation

Advanced Engineering Materials, EarlyView.
In this study, the mechanical response of Y‐shaped core sandwich beams under compressive loading is investigated, using deep feed‐forward neural networks (DFNNs) for predictive modeling. The DFNN model accurately captures stress–strain behavior, influenced by design parameters and loading rates.
