Scale-free networks embedded in fractal space [PDF]

open access: yes, 2010
The impact of inhomogeneous arrangement of nodes in space on network organization cannot be neglected in most of real-world scale-free networks. Here, we wish to suggest a model for a geographical network with nodes embedded in a fractal space in which ...

Considerations and Framework for Foveated Imaging Systems †

open access: yesPhotonics, 2018
Foveated sight as observed in some raptor eyes is a motivation for artificial imaging systems requiring both wide fields of view as well as specific embedded regions of higher resolution.

Enhanced Electromagnetic Wave Absorption Properties of Ultrathin MnO2 Nanosheet-Decorated Spherical Flower-Shaped Carbonyl Iron Powder

open access: yesMolecules, 2021
In this work, spherical flower-shaped composite carbonyl iron powder@MnO2 (CIP@MnO2) with CIP as the core and ultrathin MnO2 nanosheets as the shell was successfully prepared by a simple redox reaction to improve oxidation resistance and electromagnetic ...

Scaling in the space-time of the Internet [PDF]

open access: yesScientific Reports, 2019
AbstractThe Internet on the router level, is a complex network embedded in a geographical space. We provide experimental evidences suggesting that the average travel time for a message, with fixed length, increases roughly as the square root of the geographical distance.

Partial Block Scheme and Adaptive Update Model for Kernelized Correlation Filters-Based Object Tracking

open access: yesApplied Sciences, 2018
In visual object tracking, the dynamic environment is a challenging issue. Partial occlusion and scale variation are typical challenging problems. We present a correlation-based object tracking based on the discriminative model.

Volcanism and Deep Structures of the Moon

open access: yesSpace: Science & Technology, 2023
Volcanism is the most important endogenic geological process of the Moon, which is closely related to its internal structure and thermal history. Lunar volcanism is one of the most important topics for lunar science and explorations. Recent lunar orbital

Trans-Planckian Scale and Krein Space Quantization [PDF]

open access: yes, 2011
In this work, Krein space quantization method is applied to eliminate the Ultraviolet divergence of Green functions. This paper shows that the power spectrum of scalar field fluctuations can be calculated in the limit of short distance physics, trans ...

Scale space Radon transform

open access: yesIET Image Processing, 2021
An extension of Radon transform by using a measure function capturing the user need is proposed. The new transform, called scale space Radon transform, is devoted to the case where the embedded shape in the image is not filiform.

Global Distribution of Persistence of Total Electron Content Anomaly

open access: yesAtmosphere, 2019
To better understand the ionospheric morphology response to lithospheric activities, we study the global location preference of the positive and negative total electron content (TEC) anomalies persisting continuously for longer than 24 h at middle and ...
