Interstellar Intersubjectvity : The Significance of Shared Cognition for Communication, Empathy, and Altruism in Space

What kind of indispensable cognitive ability is needed for intelligence, sociability, communication, and technology to emerge on a habitable planet? My answer is simple: intersubjectivity. I stress the significance of intersubjectivity, of shared cognition, for extraterrestrial intelligence and interstellar communication, and argue that it is in fact crucial and indispensable for any successful in

Endoplasmic reticulum stress regulation in hematopoietic stem cells

Adult hematopoietic stem cells (HSCs) reside in bone marrow and are maintained in a dormant state within a special microenvironment, their so-called "niche". Detaching from the niche induces cell cycle progression, resulting in a reduction of the reconstitution capacity of HSCs. In contrast, fetal liver HSCs actively divide without losing their stem cell potentials. Thus, it has been unclear what

A Differential Study of the Oxygen Abundances in the Galactic Thin and Thick Disks

First results from a study into the abundance trends of oxygen in the Galactic thin and thick disks are presented. Oxygen abundances for 63nearby F and G dwarf stars, based on very high resolution spectra (R∼215 000) and high signal-to-noise (S/N>400) of the faint forbidden oxygen line at 6300Å, have been determined. Our findings can be summarized as follows: 1) at [Fe/H]<0 the oxygen trends in th

CFD Investigation of Swirl-stabilized Flexi-fuel Burner Using Methane-air Mixture for Gas Turbines

Combustion modeling based on a multi-step global reaction mechanism [1] is applied to CFD (Computational Fluid Dynamics) analysis of a scaled swirl-stabilized 4th generation premixed DLE (Dry Low Emission) burner for gas turbines. The flexi-fuel burner consists of a MAIN premixed flame, a premixed PILOT flame and a confined RPL (Rich Pilot Lean) flame. Both steady-state RANS (Reynolds Averaged Nav

Towards a theory of lexical meaning as ontologies and construals

The purpose of this paper is to propose a framework of lexical meaning, broadly along the lines of Cognitive Semantics (Langacker 1987a). The paper focuses on interpretations of adjective-noun (ADJ N ) combinations in English. Within the proposed model, all aspects of meaning are to be explained in terms of properties of ontologies in conceptual space, i.e. properties of content ontologies and sch
