Degenerate Hořava gravity [PDF]
Classical and Quantum Gravity, 2021 Abstract Hořava gravity breaks Lorentz symmetry by introducing a dynamical timelike scalar field (the khronon), which can be used as a preferred time coordinate (thus selecting a preferred space–time foliation). Adopting the khronon as the time coordinate, the theory is invariant only under time reparametrizations and spatial ...

Advances in Mathematics, 2023 Computing all critical points of a monomial on a very affine variety is a fundamental task in algebraic statistics, particle physics and other fields. The number of critical points is known as the maximum likelihood (ML) degree. When the variety is smooth, it coincides with the Euler characteristic.

EMBO reports, 2005 Mitochondria are the main sites of biological energy generation in eukaryotes. These organelles are remnants of a bacterial endosymbiont that took up residence inside a host cell over 1,500 million years ago. Comparative genomics studies suggest that the mitochondrion is monophyletic in origin.

NRF2 Is an Upstream Regulator of MYC-Mediated Osteoclastogenesis and Pathological Bone Erosion
Cells, 2020 Osteoclasts are the sole bone-resorbing cells that play an essential role in homeostatic bone remodeling and pathogenic bone destruction such as inflammatory arthritis.

The M-CSF receptor in osteoclasts and beyond
Experimental and Molecular Medicine, 2020 Bone disease: Signaling pathway offers promising drug target Drugs directed at a key signaling receptor involved in breaking down bone tissue could help treat diseases marked by pathological bone loss and destruction. In a review article, Kyung-Hyun Park-

AMPK Signaling in Energy Control, Cartilage Biology, and Osteoarthritis
Frontiers in Cell and Developmental Biology, 2021 The adenosine monophosphate (AMP)–activated protein kinase (AMPK) was initially identified as an enzyme acting as an “energy sensor” in maintaining energy homeostasis via serine/threonine phosphorylation when low cellular adenosine triphosphate (ATP ...
