Space Medicines for Space Health [PDF]

open access: yesACS 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]

open access: yes, 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 Gaussian Multiple Access Diamond Channel [PDF]

open access: yes, 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 ...

Space of Spaces as a Metric Space [PDF]

open access: yesCommunications 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.

k‐space function spaces [PDF]

open access: yesInternational 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.

Semantics-Space-Time Cube. A Conceptual Framework for Systematic Analysis of Texts in Space and Time [PDF]

open access: yes, 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.
