Daniel J. Dougherty,Joshua D. Guttmanor long periods and allow carrying gametes over long distances. Gametes can be cryopreserved and used when a suitable donor or recipient is present. Preservation of fertility is now feasible with embryo preservation. High-quality embryos can be cryopreserved at −196 °C in liquid nitrogen and can beHACK 发表于 2025-3-25 09:38:14

Thermal Properties of Silica GelsIn such systems, the distribution of matter is highly inhomogeneous, and this fact raises the problem of the nature of low-energy excitations (phonons, fractons, two-level systems) and their contributions to the low temperature properties. Fractons have been conjectured by Alexander and Orbach tIncise 发表于 2025-3-26 01:38:20
