Huh. In Philip P. Peterson's "Transport" SciFi series, the 5th book (currently only available in German), there was a "plague" in the 2020s that grounded all space missions for a long while. That book was published 15.05.2020, #COVID became "public" December 2019, only 6 months ago - kinda short publishing period. So either Peterson quickly rewrote that part and pu…

Thermodynamic phase description of charged 4D Gauss-Bonnet black holes in quantum regime
Glavan and Lin [Phys. Rev. Lett. 124, 081301 (2020)] ave argued for a 4D theory of Gauss-Bonnet (GB)gravity. This model predicts significant contributions of the GB coupling parameter $α$ to gravitational dynamics, while circumventing the Lovelock theorem and avoiding Ostrogradsky instability. As a powerful competitor to general relativity (GR), the model has been examined on various phenomenological grounds. Here, we employ a technique from information geometry to analyze the thermodynamic ph…

Alkali phenoxides in comets
Potassium was first detected in spectra of the sungrazer comet Ikeya-Seki at the heliocentric distance rh = 0.15 au and, 48 years later, in comets PanSTARRS and ISON at rh = 0.46 au. The alkali tail photoionization model provides a Na/K ratio close to the solar value. No lithium was detected in any comet: the lower limit of the Na/Li ratio was almost one order of magnitude greater than the solar ratio. Here we searched for the emissions of the alkali NaI, KI, and LiI in Comets C/2020 F3 and C/2…

Measurement of the Positive Muon Anomalous Magnetic Moment to 127 ppb
A new measurement of the magnetic anomaly $a_μ$ of the positive muon is presented based on data taken from 2020 to 2023 by the Muon $g-2$ Experiment at Fermi National Accelerator Laboratory (FNAL). This dataset contains over 2.5 times the total statistics of our previous results. From the ratio of the precession frequencies for muons and protons in our storage ring magnetic field, together with precisely known ratios of fundamental constants, we determine $a_μ = 116\,592\,0710(162) \times 10^…

A State of the Art on Recent Progress and Emerging Challenges on Energy Transfer Between Vibrating Modes Under an External Mechanical Force With Time-Varying Frequency From 2020 to 2025
In this paper, we discuss an example of current importance with a future perspective in engineering, in which excitation sources always have limited power, limited inertia, and their frequencies vary according to the instantaneous state of the vibrating system. Practical examples of non-ideal systems are considered. The most common phenomenon for this kind of system is discussed. The period considered is from 2020 to 2025. The specific properties of various models are also discussed. Directions…
