Advanced Engineering Materials, EarlyView.Developing process parameters for the laser‐based Powder Bed Fusion of metals can be a tedious task. Based on melt pool depth, the process parameters are transferable to different laser scan speeds. For this, understanding the melt pool scaling behavior is essential, particularly for materials with high thermal diffusivity, as a change in scaling ...

Volatility Spillovers in Capesize Forward Freight Agreement Markets [PDF]
Scientific Programming, 2016 This paper is to investigate spillovers in the Capesize forward freight agreements (FFAs) markets before and after the global financial crisis. The paper chooses four Capesize voyage routes FFAs (C3, C4, C5, and C7), two time-charter routes FFAs (BCIT/C average, BPI T/C average), and spot rates as research subjects, covering the periods 3 January 2006 ...

Tail probabilities for short-term returns on stocks [PDF]
, 2018 We consider the tail probabilities of stock returns for a general class of stochastic volatility models. In these models, the stochastic differential equation for volatility is autonomous, time-homogeneous and dependent on only a finite number of dimensional parameters.

Enhancing the Versatility of Photocrosslinkable Silk Fibroin Using an Eco‐Friendly Solvent
Advanced Engineering Materials, EarlyView.Silk fibroin modified with photoreactive groups enables liquid‐to‐solid transitions under light, allowing precise structural control for biofabrication. Using a sustainable calcium chloride‐ethanol‐water solvent, a novel photofibroin (PF) is shown for light‐based manufacturing like 3D printing, forming cytocompatible hydrogels for regenerative medicine.
