Machine learning holographic mapping by neural network renormalization group
Physical Review Research, 2020 Exact holographic mapping (EHM) provides an explicit duality map between a conformal field theory (CFT) configuration and a massive field propagating on an emergent classical geometry.

Geodesic and contour optimization using conformal mapping [PDF]
Journal of Global Optimization, 2016 We propose a novel optimization algorithm for continuous functions using geodesics and contours under conformal mapping.The algorithm can find multiple optima by first following a geodesic curve to a local optimum then traveling to the next search area by following a contour curve. To improve the efficiency, Newton-Raphson algorithm is also employed in

Advanced Science, EarlyView.High‐fidelity Nanopore sequencing offers a cost‐effective, portable path to uncovering viral dark matter in complex environments—but suffers from severe read‐length bias, low throughput, and limited accuracy. This study traces these limitations to core biochemical barriers and introduces CLAE, a foundational high‐fidelity platform that enables accurate,

On global geodesic mappings of ellipsoids [PDF]
AIP Conference Proceedings, 2012 In this paper we study geodesic mappings of $n$-dimensional surfaces of revolution. From the general theory of geodesic mappings of equidistant spaces we specialize to surfaces of revolution and apply the obtained formulas to the case of rotational ellipsoids.

Properties of an affine transport equation and its holonomy
, 2016 An affine transport equation was used recently to study properties of angular momentum and gravitational-wave memory effects in general relativity. In this paper, we investigate local properties of this transport equation in greater detail.

Advanced Science, EarlyView.MARCO+ TAMs dominate restrained cytotoxicity of CD8+ CTLs and ICB resistance in RCC. Mechanically, MARCO impairs MHC‐I‐mediated neoantigen cross‐presentation via the SOCS1‐JAK1‐STAT1‐NLRC5 signaling cascade in TAMs. Targeted MARCO treatment boosts macrophage antigen cross‐presentation and empowers CD8+ T cells, thereby potentiating ICB efficacy ...

Salient Object Detection Based on Background Feature Clustering
Advances in Multimedia, 2017 Automatic estimation of salient object without any prior knowledge tends to greatly enhance many computer vision tasks. This paper proposes a novel bottom-up based framework for salient object detection by first modeling background and then separating ...
