A Simple Neural Network Approach to Mineral Potential Mapping Using Open Gravity Data [PDF]
E3S Web of ConferencesAs a fundamental approach in machine learning, neural networks have evolved through phases of emergence, relative dormancy, and subsequent flourishing since their inception.

, 1993 \small The SL$(2,R)/U(1)$ coset model, with $U(1)$ an element of the third conjugacy class of $SL(2,R)$ subgroups, is considered. The resulting theory is seen to collapse to a one dimensional field theory of Liouville. Then the 2 dimensional black hole $SL(2,R)/U(1)$, with $U(1)$ a non-compact subgroup boosted by a Lorentz transformation, is considered.

Generalized 2D dilaton gravity and kinetic gravity braiding [PDF]
Classical and Quantum Gravity, 2019 Abstract We show explicitly that the nonminimal coupling between the scalar field and the Ricci scalar in 2D dilaton gravity can be recast in the form of kinetic gravity braiding (KGB). This is as it should be, because KGB is the 2D version of the Horndeski theory.

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses
Advanced Healthcare Materials, EarlyView.This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Fermions in 2D Lorentzian Quantum Gravity
, 2003 We implement Wilson fermions on 2D Lorentzian triangulation and determine the spectrum of the Dirac-Wilson operator. We compare it to the spectrum of the corresponding operator in the Euclidean background. We use fermionic particle to probe the fractal properties of Lorentzian gravity coupled to $c=1/2$ and $c=4$ matter.

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy
Advanced Healthcare Materials, EarlyView.Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Action complexity for semi-classical black holes
Journal of High Energy Physics, 2020 We adapt the complexity as action prescription (CA) to a semi-classical model of two-dimensional dilaton gravity and determine the rate of increase of holographic complexity for an evaporating black hole.

2D GRAVITY COUPLED TO TOPOLOGICAL MINIMAL MODELS [PDF]
International Journal of Modern Physics A, 1995 We discuss the properties of genus 0 correlation functions of a topological minimal model (the model Ak+1) coupled to 2D topological gravity. The action of the twisted minimal model is perturbed by nontrivial couplings to gravitational descendants, which, in turn, are constructed entirely from the fields in the matter sector of the theory.

Advanced Healthcare Materials, EarlyView.This study introduces a modular microfluidic platform that connects liver cells with live microbes to mimic key aspects of the gut–liver interaction in steatosis. Using this system, both microbial metabolites and live bacteria significantly reduced fat accumulation in liver cells, but live microbes triggered inflammation and broader metabolic changes ...
