Building a flagellum in biological outer space [PDF]
Microbial Cell, 2014 Flagella, the rotary propellers on the surface of bacteria, present a paradigm for how cells build and operate complex molecular ‘nanomachines’. Flagella grow at a constant rate to extend several times the length of the cell, and this is achieved by ...

Territories beyond possession? Antarctica and Outer Space
Polar Journal, 2017 It is often assumed that Antarctica and Outer Space are simple, un-owned spaces. To some extent, this is correct: neither of these vast areas of our planetary environment is partitioned into standard state-sovereign spatial units.

Analytic Representation of Maxwell—Boltzmann and Tsallis Thermonuclear Functions with Depleted Tail
Axioms, 2021 The closed forms of the non-resonant thermonuclear function in the Maxwell–Boltzmann and Tsallis case with depleted tail are obtained in generalized special functions. The results are written in terms of H-function of two variables. The importance of the

On the bordification of outer space [PDF]
J. Lond. Math. Soc., 2017 We give a simple construction of an equivariant deformation retract of Outer space which is homeomorphic to the Bestvina-Feighn bordification. This results in a much easier proof that the bordification is (2n-5)-connected at infinity, and hence that $Out(F_n)$ is a virtual duality group.

Mathematical Aspects of Krätzel Integral and Krätzel Transform
Mathematics, 2020 A real scalar variable integral is known in the literature by different names in different disciplines. It is basically a Bessel integral called specifically Krätzel integral. An integral transform with this Krätzel function as kernel is known as Krätzel

International-Legal Problem of Space Debris [PDF]
Advanced Space Law, 2018 The article deals with theoretical and practical legal aspects of the problem of man-made clogging of near-Earth space. The analysis shows that international space law does not cope with the current challenges and threats associated with man-made ...
