Fundamentals of momentum, heat, and mass transfer
, 2021 "Momentum transfer in a fluid involves the study of the motion of fluids and the forces that produce these motions. From Newton's second law of motion it is known that force is directly related to the time rate of change of momentum of a system ...

Advanced Optical Materials, EarlyView.Helicity‐dependent all‐optical magnetization switching was demonstrated for the Bi‐ and Ga‐substituted rare‐earth (R) iron garnet crystal thin films (Bi,Ga:RIG; R = Eu3+, Nd3+, and Y3+). The efficiency followed the order EIG > NIG > YIG. These results show the correlation between 4f orbital moment (4f〈L〉) of R3+ and helicity‐dependent optical ...

On the Impact of Spatial Momentum [PDF]
Momentum, the population growth that occurs after a fall in fertility to replacement level, has long been appreciated as a factor in the future population growth of many countries. This paper argues that another aspect of growing populations - their high

The M-theory S-matrix from ABJM: beyond 11D supergravity
Journal of High Energy Physics, 2018 We show that by studying the flat spacetime limit of the Mellin amplitude associated with the four-point correlation function of scalar operators in the stress tensor multiplet of ABJM theory, one can produce the momentum expansion of the M-theory four ...

Extrinsic Limitations of Stealthy Hyperuniform Devices
Advanced Optical Materials, EarlyView.Stealthy hyperuniform devices exhibit a scattering‐free angular region whose extent follows a simple quenching equation. Experimental measurements confirm this prediction but reveal quenching efficiencies far below theoretical expectations. Multiple scattering and finite‐size effects are quantified, establishing realistic performance limits for ...

How do Markets React to Fundamental Shocks? An Experimental Analysis on Underreaction and Momentum [PDF]
We perform a market experiment to investigate how average transaction prices react to the arrival of new information. Following a positive shock in fundamental value, prices underreact strongly; following negative shocks we find evidence of a much less ...

Advanced Optical Materials, EarlyView.Understanding exciton fine structure is crucial for optoelectronic and quantum photonic applications of lead halide perovskites. It is demonstrated that polarization‐sensitive photon‐echo spectroscopy in a magnetic field resolves exciton fine‐structure splittings hidden by inhomogeneous broadening, enabling direct determination of the bright‐dark ...

Advanced Optical Materials, EarlyView.A maskless, SLM‐driven approach enables the deterministic inscription of arbitrary topographical features in azopolymer films by mapping complex vectorial light fields onto local viscoplastic stress. This platform allows for the rapid generation and dynamic erasure of high‐aspect‐ratio micro‐spikes, offering a versatile tool for reconfigurable flat ...

Advanced Robotics Research, EarlyView.This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Gradual Information Diffusion and Asset Price Momentum [PDF]
Gradual information diffusion model predicts that as private information travels across the population, pricing accuracy would improve and asset prices would exhibit momentum as a result.
