Regular black holes from pure gravity by Pablo Bueno, Pablo A. Cano, Robie A. Hennigar

“…The theories we consider have two key properties that ensure the results are general and robust: (1) they provide a basis for (vacuum) gravitational effective field theory in five and higher-dimensions, (2) for each value of the mass, they have a unique static spherically symmetric solution. …”

Spin cobordism and the gauge group of type I/heterotic string theory by Christian Kneißl

“…Abstract Cobordism offers a unique perspective into the non-perturbative sector of string theory by demanding the absence of higher form global symmetries for quantum gravitational consistency. In this work we compute the spin cobordism groups of the classifying space of Spin(32)/ℤ2 relevant to describing type I/heterotic string theory and explore their (shared) non-perturbative sector. …”

hs $$ \mathfrak{hs} $$ -extended gravity from the IKKT matrix model by Alessandro Manta, Harold C. Steinacker, Tung Tran

“…We show that all higher-order contributions are generally suppressed and UV finite, which justifies the previous treatment of the induced gravitational action. We also obtain explicit expressions for the effective Newton constant, and determine the dynamics of the Kaluza-Klein scale ∆ K $$ {\Delta }_{\mathcal{K}} $$ of the fuzzy extra dimensions K $$ \mathcal{K} $$ .…”

Double logarithms in N $$ \mathcal{N} $$ ≥ 4 supergravity: weak gravity and Shapiro’s time delay by Agustín Sabio Vera

“…This screening of the gravitational interaction at short distances in the double logarithmic sector of the amplitudes is more acute as the number of gravitinos in the theory increases. …”

Observing Supernova Neutrino Light Curves with Super-Kamiokande. V. Distance Estimation with Neutrinos by Yudai Suwa, Akira Harada, Masamitsu Mori, Ken’ichiro Nakazato, Ryuichiro Akaho, Masayuki Harada, Yusuke Koshio, Fumi Nakanishi, Kohsuke Sumiyoshi, Roger A. Wendell

“…The radius of an NS is determined with an approximate uncertainty of 10% through observations such as X-rays and gravitational waves. By integrating this information, the distance to the supernova can be estimated with an uncertainty of within 15% at a 95% confidence level. …”

Constraining the equation of state in neutron-star cores via the long-ringdown signal by Christian Ecker, Tyler Gorda, Aleksi Kurkela, Luciano Rezzolla

“…Abstract Multimessenger signals from binary neutron star (BNS) mergers are promising tools to infer the properties of nuclear matter at densities inaccessible to laboratory experiments. Gravitational waves (GWs) from BNS merger remnants can constrain the neutron-star equation of state (EOS) complementing constraints from late inspiral, direct mass-radius measurements, and ab-initio calculations. …”

Resistance exercise training improves disuse-induced skeletal muscle atrophy in humans: a meta-analysis of randomized controlled trials by Xian Guo, Yanbing Zhou, Xinxin Li, Jinhao Mu

“…Abstract Background This meta-analysis aimed to determine whether resistance exercise training (RET) can attenuate the loss of muscle volume and function in anti-gravitational muscles, especially quadriceps and calf muscles, during immobilization/disuse conditions. …”

Unique composition and evolutionary histories of large low velocity provinces by James Panton, J. Huw Davies, Paula Koelemeijer, Robert Myhill, Jeroen Ritsema

“…Using simulations of 3-D global mantle circulation over the past 1 Gyr, we find that two antipodal LLVPs develop naturally as a consequence of Earth’s recent subduction history and the gravitational settling and stirring of SOC. Shear-wave velocity reductions in the two LLVPs are similar due to the dominating influence of temperature over composition. …”
