From Alpha to Omega: Ancient Mysteries and the Near-Death Experience
Article discussing Osirian temple rites of ancient Egypt, which may have involved ceremonial procedures deliberately calculated to induce an experience that was functionally identical to modern near-death experiences.

The Role of Misfit Strain and Oxygen Content on Formation and Evolution of Omega Precipitate in Metastable Beta-titanium Alloys
β-Ti alloys are widely used in airframe and biomedical applications due to their high ductility, high hardenability, and low elastic modulus. The phase transformations in β-Ti alloys are rather complex due to formation of metastable phases during various thermo-mechanical treatments. One such critical metastable phase, the hexagonal omega (ω) phase, can form in β-Ti alloys under quenching from the high temperature β phase and/or isothermal aging at intermediate temperature. Despite a substantial amount of reported works on the ω phase, there are several critical issues related to the ω formation need to be resolved, e.g. role of alloying elements and oxygen content. Therefore, this dissertation has attempted to provide insights into ω transformation in low misfit (Ti-Mo) and high misfit (Ti-V) binary systems as well as multicomponent (Ti-Nb-Zr-Ta) alloys. The evolution of ω structure, morphology and composition from the early stage (β-solution+quenched) to later stages after prolonged aging are systematically investigated by coupling transmission electron microscopy (TEM), atom probe tomography (APT) and high-energy synchrotron X-ray diffraction techniques. The influence of aging temperature and duration on characteristic of ω phase in Ti-Mo, and Ti-V alloys is addressed in details. It is found that compositional changes during aging can alter the structure, …

A Contribution of Tipler's Omega Point Theory to Near-Death Studies
Article presenting Frank Tipler's concepts and arguments, and highlighting the value of his orientation for near-death studies. Tipler's work takes the steam out of scientific rejection of religious, spiritual, or noetic phenomena, and makes it possible to accept these phenomena while maintaining a strictly scientific posture.
