Space of Spaces as a Metric Space [PDF]
Communications in Mathematical Physics, 2000 In spacetime physics, we frequently need to consider a set of all spaces (`universes') as a whole. In particular, the concept of `closeness' between spaces is essential. However, there has been no established mathematical theory so far which deals with a space of spaces in a suitable manner for spacetime physics.

Space Medicines for Space Health [PDF]
ACS Medicinal Chemistry Letters, 2022 Scientists from around the world are studying the effects of microgravity and cosmic radiation via the "off-Earth" International Space Station (ISS) laboratory platform. The ISS has helped scientists make discoveries that go beyond the basic understanding of Earth. Over 300 medical experiments have been performed to date, with the goal of extending the

Distributional Energy-Momentum Densities of Schwarzschild Space-Time [PDF]
, 1997 For Schwarzschild space-time, distributional expressions of energy-momentum densities and of scalar concomitants of the curvature tensors are examined for a class of coordinate systems which includes those of the Schwarzschild and of Kerr-Schild types as

The Final Count Down: A Review of Three Decades of Flight Controller Training Methods for Space Shuttle Mission Operations [PDF]
, 2011 Operations of human spaceflight systems is extremely complex; therefore, the training and certification of operations personnel is a critical piece of ensuring mission success. Mission Control Center (MCC-H), at the Lyndon B.

The Gaussian Multiple Access Diamond Channel [PDF]
, 2015 In this paper, we study the capacity of the diamond channel. We focus on the special case where the channel between the source node and the two relay nodes are two separate links with finite capacities and the link from the two relay nodes to the ...

Semantics-Space-Time Cube. A Conceptual Framework for Systematic Analysis of Texts in Space and Time [PDF]
, 2018 We propose an approach to analyzing data in which texts are associated with spatial and temporal references with the aim to understand how the text semantics vary over space and time.

Type space on a purely measurable parameter space [PDF]
, 2005 Several game theoretical topics require the analysis of hierarchical beliefs, particularly in incomplete information situations. For the problem of incomplete information, Hars´anyi suggested the concept of the type space.

International Journal of Mathematics and Mathematical Sciences, 1980 A study is made of the properties on X which characterize when Cπ(X) is a k‐space, where Cπ(X) is the space of real‐valued continuous functions on X having the topology of pointwise convergence. Other properties related to the k‐space property are also considered.

Phase space path integral in curved space [PDF]
, 2000 Phase space path integral is worked out in a riemannian geometry, by employing a prescription for the infinitesimal propagator that takes riemannian normal coordinates and momenta on an equal footing.
