Four-Dimensional (Bio-)printing: A Review on Stimuli-Responsive Mechanisms and Their Biomedical Suitability
(MDPI AG, 2020-12)The applications of tissue engineered constructs have witnessed great advances in the last few years, as advanced fabrication techniques have enabled promising approaches to develop structures and devices for biomedical ... -
Four-dimensional anisotropic mesh adaptation for spacetime numerical simulations
(Massachusetts Institute of Technology, 2019)Engineers and scientists are increasingly relying on high-fidelity numerical simulations. Within these simulations, mesh adaptation is useful for obtaining accurate predictions of an output of interest subject to a ... -
A four-equation two-phase flow model for sodium boiling simulation of LMFBR fuel assemblies
(Cambridge, Mass. : Massachusetts Institute of Technology, Energy Laboratory, 1982, 1982)A three-dimensional numerical model for the simulation of sodium boiling transients has been developed. The model uses mixture mass and energy equations, while employing a separate momentum equation for each phase. Thermal ... -

Four-graviton scattering to three loops in N = 8 $$ \mathcal{N}=8 $$ supergravity
(Springer Berlin Heidelberg, 2019-05-03)Abstract We compute the three-loop scattering amplitude of four gravitons in ... -
Four-particle scattering amplitudes in QCD at NNLO to higher orders in the dimensional regulator
(Springer Berlin Heidelberg, 2019-12-30)Abstract We compute all helicity amplitudes for four particle scattering in massless QCD with nf fermion flavours to next-to-next-to-leading order (NNLO) in perturbation theory. In particular, we consider ... -
Four-volume cutoff measure of the multiverse
(American Physical Society (APS), 2020-02)Predictions in an eternally inflating multiverse are meaningless unless we specify the probability measure. The scale-factor cutoff is perhaps the simplest and most successful measure which avoids catastrophic problems ... -
Four-way lossless outphasing and power combining with hybrid microstrip/discrete combiner for microwave power amplification
(Institute of Electrical and Electronics Engineers (IEEE), 2013-06)This work demonstrates a four-way outphasing and power combining system for microwave power amplification using a novel power combining network. The ideally lossles combining network is implemented using a combination of ... -
Four-Way Microstrip-Based Power Combining for Microwave Outphasing Power Amplifiers
(Institute of Electrical and Electronics Engineers (IEEE), 2014-09)A lossless multi-way outphasing and power combining system for microwave power amplification is presented. The architecture addresses one of the primary drawbacks of Chireix outphasing; namely, the sub-optimal loading ... -
Four-well highly strained quantum cascade lasers grown by metal-organic chemical vapor deposition
(Institute of Electrical and Electronics Engineers, 2009-08)We demonstrate a novel four-well injectorless design with short wavelength (5.5 mum) and room temperature operation utilizing highly strained Ga[subscript 0.35] In[subscript 0.6] As/Al[subscript 0.70] In[subscript 0.30]As ... -
Fourientations and the Tutte polynomial
(Springer International Publishing, 2017-09)A fourientation of a graph is a choice for each edge of the graph whether to orient that edge in either direction, leave it unoriented, or biorient it. Fixing a total order on the edges and a reference orientation of the ... -
Fourier analysis on the hypercube, the coefficient problem, and applications
(Massachusetts Institute of Technology, 2020)In this dissertation, we primarily study some problems that revolve around Fourier analysis. More specifically we focus on the magnitudes of the frequency components. Firstly, we perform a study on the hypercube. It is ... -
Fourier depth of field
(Association for Computing Machinery (ACM), 2009-04)Optical systems used in photography and cinema produce depth-of-field effects, that is, variations of focus with depth. These effects are simulated in image synthesis by integrating incoming radiance at each pixel over the ... -
Fourier dimension and spectral gaps for hyperbolic surfaces
(Springer Nature, 2017)© 2017, Springer International Publishing AG. We obtain an essential spectral gap for a convex co-compact hyperbolic surface M= Γ \ H2 which depends only on the dimension δ of the limit set. More precisely, we show that ... -
Fourier magnetic imaging with nanoscale resolution and compressed sensing speed-up using electronic spins in diamond
(Nature Publishing Group, 2015-08)Optically detected magnetic resonance using nitrogen–vacancy (NV) colour centres in diamond is a leading modality for nanoscale magnetic field imaging, as it provides single electron spin sensitivity, three-dimensional ... -
