Irreversibility of time in general relativity [PDF]
Известия Саратовского университета. Новая серия: Физика, 2022 Background and Objectives: The equations of classical dynamics of particles and waves admit solutions with the reverse flow of time. Therefore, it is generally assumed that classical dynamics does not reflect the irreversibility of time.

Tidskrift för Litteraturvetenskap, 2021 Gravitation: Modes of Reading in the Anthropocene In this article, I suggest ‘gravitation’ as a new way of reading in and for the anthropocene, which is characterised by environmentally destructive ‘social acceleration’.

The Gravitation of the Moon Plays Pivotal Roles in the Occurrence of the Acute Myocardial Infarction
Environmental Health Insights, 2008 Acute myocardial infarction (AMI) is a social burden. However, being able to predict AMI could lead to prevention. A previous study showed only the relation between the lunar phase and the occurrence of AMI, but the period it takes for the moon to orbit ...

Weak Deflection Angle and Shadow by Tidal Charged Black Hole
Universe, 2021 In this article, we calculate the deflection angle of a tidal charged black hole (TCBH) in weak field limits. First, we obtain the Gaussian optical curvature and then apply the Gauss–Bonnet theorem on it.

Scalar–Tensor–Vector Modified Gravity in Light of the Planck 2018 Data
Universe, 2021 The recent data release by the Planck satellite collaboration presents a renewed challenge for modified theories of gravitation. Such theories must be capable of reproducing the observed angular power spectrum of the cosmic microwave background radiation.

The total mass of the early-type galaxy NGC 4649 (M60) [PDF]
Serbian Astronomical Journal, 2008 In this paper the problem of the total mass and the total mass-to-light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two independent techniques: the X-ray methodology which is based on the temperature of the X-ray halo of NGC

Gravitation-based personalized recommendation algorithm
工程科学学报, 2015 A recommendation algorithm is proposed by introducing the universal law of gravitation into a recommendation system. This new algorithm is named as the gravitation-based personalized recommendation (GBPR) algorithm.

General relativistic theory of gravity and electricity
Revista de Investigación de Física, 2022 As gravitation and electromagnetism are closely analogous long-range interactions, and the current formulation of gravitation is given in terms of geometry, we expect the latter also to appear throug the geometry.
