On the relationship between variable Wiener index and variable Szeged index [PDF]
We resolve two conjectures of Hriňáková, Knor and Škrekovski (2019) concerning the relationship between the variable Wiener index and variable Szeged index for a connected, non-complete graph, one of which would imply the other. The strong conjecture is that for any such graph there is a critical exponent in $(0,1]$, below which the variable Wiener ...

Equiseparable chemical trees [PDF]
Let n1(e|T) and n2(e|T) denote the number of vertices of a tree T, lying on the two sides of the edge e. Let T1 and T2 be two trees with equal number of vertices, let e be an edge of T1 and f an edge of T2.

What Affects the Use Flexibility of Pocket Parks? Evidence from Nanjing, China
The use flexibility of pocket parks is one of the essential factors that determine their service compatibility, efficiency, and attraction for park users in densely populated cities. To examine the factors that affect the use flexibility of pocket parks,

Percolation Analysis of a Wiener Reconstruction of the IRAS 1.2 Jy Redshift Catalog [PDF]
We present percolation analyses of Wiener Reconstructions of the IRAS 1.2 Jy Redshift Survey. There are ten reconstructions of galaxy density fields in real space spanning the range $\beta= 0.1$ to $1.0$, where ${\beta}={\Omega^{0.6}}/b$, $\Omega$ is the

Logarithmic Gradient Transformation and Chaos Expansion of Ito Processes [PDF]
Since the seminal work of Wiener, the chaos expansion has evolved to a powerful methodology for studying a broad range of stochastic differential equations. Yet its complexity for systems subject to the white noise remains significant.

Image Encryption Algorithm Based on Novel Chaotic System and Binary Block CompressedSensing [PDF]
An image encryption scheme based on novel integer chaotic system and block compressed sensing(BCS) is proposed for embedded devices.Firstly,an integer chaotic system is designed by perturbing one-dimensional variable parameters.Then,in the compressed ...

The microbial community structure of the Dupnisa cave in Kırklareli, Turkey
Cave ecosystems count to be extreme environments due to their stable temperature, darkness, high humidity rates, and limited organic materials. In this context, these ecosystems represent invaluable laboratories for microbiological studies.
