Article Synopsis
- This study investigates the use of decision markets to choose which social science experiments should be replicated, focusing on outcomes of 41 close replications of MTurk experiments.
- Researchers found that the highest-ranking studies in the market had an 83% replication success rate, while the lowest-ranking studies had only a 33% success rate.
- Overall, about 54% of the experiments were successfully replicated, with effect sizes averaging 45% of the original values, indicating that replicability in MTurk experiments is on par with past laboratory replication projects.
The L-PBF process belongs to the most modern methods of manufacturing complex-shaped parts. It is used especially in the automotive, aviation industries, and in the consumer products industry as well. Numerical simulation in the powder sintering process is a means of optimizing time efficiency, accuracy and predicting future errors.

- - A 73-year-old man was hospitalized due to epigastric pain and fainting, showing elevated troponin levels and a unique ST-elevation on an electrocardiogram.
- - Coronary angiography revealed multi-vessel coronary artery disease, leading to a series of interventions including angioplasty and stenting on multiple arteries.
- - This case illustrates that in some acute coronary syndrome instances, rare ST elevation anomalies can indicate the presence of significant multi-vessel disease.
Additive manufacturing, including laser powder bed fusion, offers possibilities for the production of materials with properties comparable to conventional technologies. The main aim of this paper is to describe the specific microstructure of 316L stainless steel prepared using additive manufacturing. The as-built state and the material after heat treatment (solution annealing at 1050 °C and 60 min soaking time, followed by artificial aging at 700 °C and 3000 min soaking time) were analyzed.
View Article and Find Full Text PDFLaser powder bed fusion (LPBF) is an additive manufacturing technology that implies using metal powder as a raw material. The powders suitable for this kind of technology must respect some specific characteristics. Controlled gas atomization and post-processing operations can strongly affect the final properties of the powders, and, as a consequence, the characteristics of the bulk components.
