Advanced Engineering Materials, EarlyView.Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Noisy Information, Interest Rate Shocks and the Great Moderation [PDF]
In this paper we quantitatively evaluate the hypothesis that the Great Moderation is partly the result of a less activist monetary policy. We simulate a New Keynesian model where the central bank can only observe a noisy estimate of the output gap and ...

Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

Adiabatic preparation of thermal states and entropy-noise relation on noisy quantum computers
npj Quantum InformationWe consider the problem of preparing thermal equilibrium states at finite temperature on quantum computers. Assuming thermalization, we show that states that are locally at thermal equilibrium can be prepared by evolving adiabatically an initial thermal ...

Efficient Bayesian Detection of Faint Curved Edges in Noisy Images
IEEE AccessDetecting edges in images is a fundamental problem in computer vision with many applications. Many edge detection algorithms have been proposed over the past several decades. These algorithms can deal effectively with the problem, but often face difficulties when applied to images taken under poor visual conditions of faint edges and noisy backgrounds.

Bilateral J-Curve Between Thailand and Her Trading Partners [PDF]
Previous studies that tested the J-Curve phenomenon, employed aggregate trade data. More recent studies however, have used bilateral data in testing the phenomenon. They have all concentrated investigating the J-Curve between the U.S.

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.
