Our analysis provides one of the first quantitative constraints that shows that the range is still in its infancy: In contrast to several other mountain ranges, the Alps have still more than half of their evolution to a geomorphic steady state to go. Even their relative stage of evolution is unclear: Are the Alps still growing, in a steady state or even decaying? Using the mean slope at given catchment size as a new geomorphic parameter we analyse the topography of the Alps. Hergarten, Stefan Stüwe, Kurt Wagner, ThomasĪlthough the Alps are among the best studied mountain ranges on Earth, the age of their topography is almost unknown. The heavy ALP plays a role of the waterfall field in hybrid inflation, and reheats the Universe, and it can be searched for in various experiments such as SHiP. We also discuss a case with multiple ALPs, where the coupling to photons can be enhanced in the early Universe by an order of magnitude or more, which enlarges the parameter space for the ALP miracle. Furthermore, thermalized ALPs contribute to hot dark matter and its abundance is given in terms of the effective number of extra neutrino species, Δ Neff simeq 0.03, which can be tested by the future CMB and BAO observations. The suggested parameter region is within the reach of the next generation axion helioscope, IAXO, and high-intensity laser experiments in the future. We find that the observed CMB and matter power spectrum as well as the dark matter abundance point to an ALP of mass mphi = Script O(0.01) eV and the axion-photon coupling gphi γ γ = Script O(10-11) GeV-1: the ALP miracle. After inflation, most of the ALPs decay and evaporate into plasma through a coupling to photons, and the remaining ones become dark matter. In a class of the minimal axion hilltop inflation, the effective masses at the maximum and mimimum of the potential have equal magnitude but opposite sign, so that the ALP inflaton is light both during inflation and in the true vacuum. We propose a scenario where both inflation and dark matter are described by a single axion-like particle ( ALP) in a unified manner. The ALP miracle: unified inflaton and dark matterĭaido, Ryuji Takahashi, Fuminobu Yin, Wen The results of anisotropic tomography provide important new information on the complex mantle structure and dynamics of the Alps and adjacent regions. ALP+ cells expressed significantly higher levels of stemness associated genes, NANOG, OCT4 and SOX than ALP− cells at low cell passages of 2-3 (p Vpv) in the low-velocity mantle wedge, which may reflect the subvertical plate subduction and its induced mantle flow. In the present study, we examined ALP+ and ALP− hPDLSC subpopulations, their surface markers STRO-1 and CD146, and the expression of stemness genes at various cell passages. Information regarding ALP subpopulation of human periodontal ligament stem cells (hPDLSCs) is limited. Tissue-nonspecific alkaline phosphatase ( ALP) is associated with mineral tissue forming cells as well as stem cells. Tran, Quynh T El-Ayachi, Ikbale Bhatti, Fazal-Ur-Rehman Bahabri, Rayan Al-Habib, Mey Huang, George TJĬharacterizing subpopulations of stem cells is important to understand stem cell properties. With the exception of SnTe and, to a lesser extent, PbTe, the results are in reasonable agreement with the available experimental data and values derived from other models.ĭifferential Properties of Human ALP+ Periodontal Ligament Stem Cells vs Their ALP- Counterparts The calculations are based on a model developed by Kagan and Maslow for binary compounds with rocksalt structure.
