Neural Fields for Highly Accelerated 2D Cine Phase Contrast MRI
Advanced Science, EarlyView.ABSTRACT 2D cine phase contrast (CPC) MRI provides quantitative information on blood velocity and flow within the human vasculature. However, data acquisition is time‐consuming, motivating the reconstruction of the velocity field from undersampled measurements to reduce scan times. In this work, neural fields are proposed as a continuous spatiotemporal

The Optimization of a Volute Downstream of a Vaned Radial Compressor
International Journal of Turbomachinery, Propulsion and PowerVolutes downstream of radial compressor impellers and their respective diffusors have proven to be useful flow geometries, as they collect and deflect the swirling mass flow efficiently and feature a compact shape.

European Journal of Combinatorics, 1988 Let \(M=(E,{\mathcal F})\) be a matroid on the underlying set E (\({\mathcal F}\) is the collection of flats of M). A simple matroid \(A=(S,{\mathcal T})\) is the adjoint of M if \(r_ M(E)=r_ A(S)\) and there exists an injection \(\phi\) : \({\mathcal F}\to {\mathcal T}\) such that for \(F_ 1,F_ 2\in {\mathcal F}\), if \(F_ 1\subseteq F_ 2\) then ...

Exact Discrete Stochastic Simulation With Deep‐Learning‐Scale Gradient Optimization
Advanced Science, EarlyView.A 203,796‐parameter gene regulatory network classifies handwritten digits with 98.4% accuracy using exact stochastic dynamics. The framework decouples forward simulation from backward differentiation, making continuous‐time Markov chain models compatible with deep‐learning optimization.

On Dynamical Adjoint Functor [PDF]
Applied Categorical Structures, 2011 We give an explicit formula relating the dynamical adjoint functor and dynamical twist over nonalbelian base to the invariant pairing on parabolic Verma modules. As an illustration, we give explicit $U(sl(n))$- and $U_\hbar(sl(n))$-invariant star product on projective spaces.

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels
Advanced Science, EarlyView.Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

Quantum‐Like Dynamics in Whole‐Brain Models of the Human Connectome
Advanced Science, EarlyView.Quantum‐like dynamics in the human brain. The level of quantum‐like behavior in a non‐quantum system of coupled oscillators is regulated by the spectral gap of the coupling graph. Whole‐brain modelling using QL fits the empirical data significantly better and has a lower model‐derived energy cost than the non‐QL model.
