The ordered arrangement of π-π networks within nanostructures is advantageous for the construction artificial electronic transport (ETp) systems. Building such structures with biocompatible peptides offers a potential prescribed structural addressability and enhanced ETp capability implications targeted neural tissue engineering. However, creating tunnels in peptide composed entirely natural amino acids presents challenges resulting from flexible side chains free movement aromatic residues,...
Since the outbreak of Ukrainian-Russian conflict on 24 February 2022, Ukraine’s economy, society, and cities have been devastated struck multiple fronts, with large numbers refugees fleeing to neighboring countries. The lighting systems in Ukrainian severely restricted due Russian missile bombing curfew policies. power shortages adversely affected livelihoods residents dramatically. For a timely assessment shortages’ extent population Ukraine, this study tracked dynamics nighttime light...
The skylight polarization pattern contains rich information for navigation, meteorological monitoring, and remote sensing. In this paper, we propose a high-similarity analytical model by considering the influence of solar altitude angle on neutral point position variations distribution polarized skylight. A novel function is built to determine relationship between elevation based large number measured data. experimental results show that proposed achieves higher similarity data compared with...
Many insects use the pattern of polarized light in sky as a navigational cue. In this study, we sensory ability source inspiration to create computational orientation model based on an artificial neural network (POL-ANN). After training phase using numerically generated polarization patterns, stable and convergent networks are obtained. We undertook series verification tests four typical but different conditions showed that post-trained were able make accurate prediction direction sun....
Attention on, and interest in, life satisfaction has increased worldwide. However, research on focused toward the urban dwellers’ residential community is mainly from western countries, limited China solely geriatric population via a narrowly constrained perspective. This study, therefore, aimed to investigate urbanites’ their community, combining psychological (behavioral engagement, mental state of flow, cognitive identity), physical (PREQIs-perceived environment quality indicators: e.g.,...
We present a computationally inexpensive analytical model for simulating celestial polarization patterns in variable conditions. combine both the singularity theory of Berry et al (2004 New J. Phys. 6 162) and intensity Perez (1993 Sol. Energy 50 235–245) such that our single describes three key sets data: (1) overhead distribution degree as well existence neutral points sky; (2) change sky function turbidity atmosphere; (3) wavelength, calculated this work from ultra-violet to near...
Mantis shrimp have complex visual sensors, and thus, they both color vision polarization vision, are adept at using information for tasks, such as finding prey. In addition, mantis shrimp, almost unique among animals, can perform three-axis eye movements, pitch, yaw, roll. With this behavior, contrast in their field of view be adjusted real time. Inspired by this, we propose a bionic model that adaptively enhance vision. model, pixel array is used to simulate compound array, the angle (AoP)...
Researchers have found that some animals can use the skylight polarization pattern for navigation. It is also expected to human navigating in near future. However, challenge need a more accurate and efficient model of imaging always felt. In this paper, three improved models are proposed. The proposed utilize analysis distribution after system. Given system distorted, focus paper on degree distortion these models. Experiments clear weather conditions demonstrate operates close actual...
Stomatopods are creatures that have a unique ability to manipulate their environment by detecting polarized light for finding prey, choosing habitat, and navigation. In this study, based on the concept of polarization distance proposed Martin Jet al2014 [Proc. R. Soc. B281, 20131632], we analyzed several multi-channel models. The simulation experimental results revealed compared other models, four-channel model can significantly enhance contrast between target background, it exhibits...
A frequency-doubling optoelectronic oscillator (OEO) has been proposed. In the proposed device, several passive components are introduced into traditional OEO to handle polarization state of laser in feedback loop.
