Facile Fabrication of Large‐Area Biofunctionalized Metallic Nanostructures for High Performance Affinity Plasmonic Biosensors

Advanced Materials Technologies, EarlyView.
A novel approach enables facile and reproducible fabrication of gold nanoparticle arrays with tunable near‐infrared plasmonic properties and enhanced sensing accuracy. Using advanced lithography and ion milling, combined with innovative surface chemistry, the approach minimizes ohmic losses and non‐specific sorption, improving biomolecular detection ...

Stationary patterns of a diffusive predator-prey model with Crowley-Martin functional response [PDF]

arXiv, 2017
A diffusive predator-prey system with predator interference and Neumann boundary conditions is considered in this paper. We derive some results on the existence and nonexistence of nonconstant stationary solutions. It is shown that there exist no nonconstant stationary solutions when the effect of the predator interference is strong or the conversion ...

Switching model with two habitats and a predator involving group defence

, 1998
Switching model with one predator and two prey species is considered. The prey species have the ability of group defence. Therefore, the predator will be attracted towards that habitat where prey are less in number.

Fear on the move: predator hunting mode predicts variation in prey mortality and plasticity in prey spatial response.

Journal of Animal Ecology, 2014
Ecologists have long searched for a framework of a priori species traits to help predict predator-prey interactions in food webs. Empirical evidence has shown that predator hunting mode and predator and prey habitat domain are useful traits for ...

Fabrication Optimization of van der Waals Metasurfaces: Inverse Patterning Boosts Resonance Quality Factor

Advanced Optical Materials, EarlyView.
An optimized fabrication approach for the nanostructuring of optical metasurfaces from van der Waals materials like hexagonal boron nitride is presented. The resonator geometries show enhanced geometric homogeneity, resulting in a significant increase in quality factors of symmetry‐protected bound states in the continuum resonances.

Study of LG-Holling type III predator-prey model with disease in predator [PDF]

arXiv, 2017
In this article, a Leslie-Gower Holling type III predator-prey model with disease in predator has been developed from both biological and mathematical point of view. The total population is divided into three classes, namely, prey, susceptible predator and infected predator.

Carbon‐Coated Moth‐Eye Structure: An Ultrabroadband THz‐DUV Near‐Perfect Absorber

Advanced Optical Materials, EarlyView.
A silicon moth‐eye surface coated with pyrolytic carbon achieves >98% absorption from 1 to 1200 THz by combining gradient‐index matching with PyC's broadband conductivity, forming an ultra‐broadband absorber from THz to deep UV. Experimental results and simulations agreed well.

Chaos control via feeding switching in intraguild predation systems [PDF]

arXiv, 2014
In the present paper we study a tri-trophic Lotka-Volterra food web model with omnivory and predator switching. We observe that if the intensity of predator switching increases the chaotic behavior of the omnivory model will be reduced. We conclude that the predator switching mechanism enhances the stability of an otherwise chaotic system.

Effects of demographic stochasticity on biological community assembly on evolutionary time scales

, 2010
We study the effects of demographic stochasticity on the long-term dynamics of biological coevolution models of community assembly. The noise is induced in order to check the validity of deterministic population dynamics.

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

Advanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...
