Small Structures, EarlyView.The review comprehensively summarizes the binding behaviors and multidimensional applications of malachite green with diverse functional nucleic acids. By integrating structural mechanisms, comparative analysis, and application strategies across eight domains, it provides theoretical guidance and future perspectives for developing intelligent nucleic ...

Switching Internal Times and a New Perspective on the `Wave Function of the Universe’
Universe, 2019 Despite its importance in general relativity, a quantum notion of general covariance has not yet been established in quantum gravity and cosmology, where, given the a priori absence of coordinates, it is necessary to replace classical frames with ...

Theological Doctrines as Scientific Theories? Thinking along with and beyond McGrath
International Journal of Systematic Theology, EarlyView.Abstract McGrath's recent analysis of the parallels between scientific theory formation and the development of theological doctrine in The Nature of Christian Doctrine (OUP, 2024) is insightful and largely compelling, but also raises some questions and areas for further exploration. First, there is a remarkable back‐and‐forth between uses of ‘doctrine’

Classical and quantum cosmology of minimal massive bigravity
Physics Letters B, 2016 In a Friedmann–Robertson–Walker (FRW) space–time background we study the classical cosmological models in the context of recently proposed theory of nonlinear minimal massive bigravity.

The simplicity of physical laws
Noûs, EarlyView.Abstract Physical laws are strikingly simple, yet there is no a priori reason for them to be so. I propose that nomic realists—Humeans and non‐Humeans—should recognize simplicity as a fundamental epistemic guide for discovering and evaluating candidate physical laws.

LETTER: A Simple Quantum Cosmology [PDF]
General Relativity and Gravitation, 2001 A simple and surprisingly realistic model of the origin of the universe can be developed using the Friedmann equation from general relativity, elementary quantum mechanics, and the experimental values of h, c, G and the proton mass. The model assumes there are N space dimensions (with N > 6) and the potential constraining the radius r of the ...

Lessons from the void: What Boltzmann brains teach
Analytic Philosophy, EarlyView.Abstract Some physical theories predict that almost all brains in the universe are Boltzmann brains, that is, short‐lived disembodied brains that are accidentally assembled as a result of thermodynamic or quantum fluctuations. Physicists and philosophers of physics widely regard this proliferation as unacceptable, and so take its prediction as a basis ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
