Rainbow-Like Black-Hole Metric from Loop Quantum Gravity
Universe, 2018 Hypersurface deformation algebra consists of a fruitful approach to derive deformed solutions of general relativity based on symmetry considerations with quantum-gravity effects, of which the linearization has been recently demonstrated to be connected ...

Hot Injection Synthesis of Ultrathin Bi2Se3 Nanosheets With Controllable Dimensions
Small Methods, EarlyView.Graphic of hot‐injection method for synthesizing Bi2Se3${\rm Bi}_2{\rm Se}_3$ nanoplatelets of controlled shape, thickness, and lateral size. The ultra‐thin regime is achievable, which is interesting for studying topological phase transitions. ABSTRACT In this work, a synthesis method for colloidal nanoplatelets (NPLs) of the topological insulator ...

Modern Theology, EarlyView.Abstract This essay, designed as a complement to opinions expressed by Rowan Williams and some speakers at the conference in his honour, explores features of early Christianity which suggest a positive evaluation of artificial intelligence. Noting that the fear of reducing humans to machines has been joined in the modern age by the fear that machines ...

Entropic motion in loop quantum gravity [PDF]
Canadian Journal of Physics, 2016 Entropic forces result from an increase of the entropy of a thermodynamical physical system. It has been proposed that gravity is such a phenomenon and many articles have appeared in the literature concerning this problem. We propose a method that may reproduce an entropic force and may be related to loop quantum gravity.

Spontaneous compactification in 2D induced quantum gravity
, 1992 Spontaneous compactification ---on a $R^1\times S^1$ background--- in 2D induced quantum gravity (considered as a toy model for more fundamental quantum gravity) is analyzed in the gauge-independent effective action formalism.

New Phytologist, EarlyView.Summary Experimental evolution under elevated temperatures has generated heat‐evolved (HE) strains of Symbiodiniaceae that enhance coral bleaching tolerance. However, the biomolecular mechanisms underlying this resilience remain poorly understood. We conducted a laboratory heat‐stress experiment and applied synchrotron‐based Fourier transform infrared (

Plant Biotechnology Journal, EarlyView.ABSTRACT Protoberberine alkaloids are a characteristic group of natural products in Coptis plants known for their notable pharmacological activities. However, the structural similarity and the substrate promiscuity of their biosynthetic enzymes have left the precise synthetic pathways remain unclarified, posing challenges to regulate product formation.
