Acta Universitatis Carolinae Geographica, 2021 Transport is one of the important factors influencing the arrangement of spatial relations and creating of spatial interactions in society. This proposition can also be applied to the forming of links within an urban system. In connection with this it is

Hopf coactions on commutative algebras generated by a quadratically independent comodule [PDF]
, 2016 Let A be a commutative unital algebra over an algebraically closed field k of characteristic not equal to 2, whose generators form a finite-dimensional subspace V, with no nontrivial homogeneous quadratic relations. Let Q be a Hopf algebra that coacts on

THE LIBERAL HISTORIOGRAPHY OF NORTH CAUCASUS CLASS RELATIONS OF THE XIX CENTURY
Гуманитарные и юридические исследования, 2021 The article analyzes the liberal historiography of the North Caucasian social relations and the transformation of these relations in the 1860s and 1870s. This historiographic problem is still poorly understood and the authors made a successful attempt in

Some new bounds on the general sum–connectivity index [PDF]
Communications in Combinatorics and Optimization, 2020 Let $G=(V,E)$ be a simple connected graph with $n$ vertices, $m$ edges and sequence of vertex degrees $d_1 \ge d_2 \ge \cdots \ge d_n>0$, $d_i=d(v_i)$, where $v_i\in V$. With $i\sim j$ we denote adjacency of vertices $v_i$ and $v_j$. The general sum--

Non-linear Conductance, Rectification, and Mechanosensitive Channel Formation of Lipid Membranes
Frontiers in Cell and Developmental Biology, 2021 There is mounting evidence that lipid bilayers display conductive properties. However, when interpreting the electrical response of biological membranes to voltage changes, they are commonly considered as inert insulators.

A Unified Scaling Law in Spiral Galaxies [PDF]
, 2000 We investigate the origin of a unified scaling relation in spiral galaxies. Observed spiral galaxies are spread on a plane in the three-dimensionallogarithmic space of luminosity L, radius R and rotation velocity V.

Grundlagen §64: an alternative strategy to account for second-order abstraction
Principia: An International Journal of Epistemology, 2022 A famous passage in Section 64 of Frege’s Grundlagen may be seen as a justification for the truth of abstraction principles. The justification is grounded in the procedure of content recarving which Frege describes in the passage.
