Structural and Dynamic Stability of Model Predator-Prey Systems [PDF]

, 1976
A modified set of Volterra's differential equations for dynamics of prey and predator populations is analyzed. This modification takes three effects into consideration: (1) Satiation of predator resulting in the inability of either predation rate or ...

Moth‐Wing‐Inspired Multifunctional Metamaterials

Advanced Materials, EarlyView.
This study develops a moth‐wing‐inspired heterogeneous metamaterial that achieves synergistic broadband sound absorption, mechanical energy dissipation, and thermal insulation within a lightweight architected framework. Combining bioinspired gradient design, genetic‐algorithm optimization, and additive manufacturing, the bionic heterogeneous acoustic ...

Recent Advances in Collective Behaviors of Micro/Nanomotor Swarms

Advanced Materials, EarlyView.
This review describes the driving forces behind collective motion, explores the self‐organization of micro/nano swarms across zero‐dimensional (0D), one‐dimensional (1D), two‐dimensional (2D), and three‐dimensional (3D) spaces, and highlights their potential in drug delivery, environmental monitoring, and smart devices.

Interaction strength and harvest intensity mediate predator–prey dynamics on coral reefs

Ecosphere
Understanding predator–prey relationships is fundamental to our knowledge of the stability and resilience of ecological systems. These dynamics are shaped by both ecological factors, like interaction strength, and anthropogenic factors, like harvest ...

Phenologically-Structured Predator-Prey Dynamics with Temperature Dependence [PDF]

Bulletin of Mathematical Biology, 2007
Studies document the fact that temperature changes strongly affect interactions in many consumer-resource systems through altered, or shifted, phenologies. The mistiming of events, such as migration or emergence times, or the contraction or expansion of development times can upset the normal synchronization and lead to increased or decreased predation ...

Potent Liver‐Tropic mRNA Lipid Nanoparticles: ApoE‐Mediated Delivery Through a Low‐Density Lipoprotein Receptor Independent Uptake Mechanism

Advanced Materials, EarlyView.
Helper and ionizable lipids play a crucial role in determining ApoE binding and subsequent liver tropism and LDLR‐mediated uptake. Ionizable lipids primarily govern the LDLR‐independent uptake pathway. This complementary interplay between lipid components ultimately governs LNP delivery performance and therapeutic efficacy in the liver.

A note on predator-prey dynamics in radiocarbon datasets

Peer Community Journal
Predator-prey interactions have been a central theme in population ecology for the past century, but real-world data sets only exist for recent, relatively short (

Evolutionary dynamics of predator-prey systems: an ecological perspective [PDF]

Journal of Mathematical Biology, 1996
Evolution takes place in an ecological setting that typically involves interactions with other organisms. To describe such evolution, a structure is needed which incorporates the simultaneous evolution of interacting species. Here a formal framework for this purpose is suggested, extending from the microscopic interactions between individuals--the ...

Label‐Free Sensing of Coronaviral Sequences via Kretschmann‐Configuration Reflectance Spectroscopic Ellipsometry: Sensitivity, Specificity, and Interfacial Effects

Advanced Materials Interfaces, EarlyView.
Spectroscopic ellipsometry in the Kretschmann‐Raether configuration (KRSE) is employed to characterize a DNA‐functionalized platform for viral sequence recognition. By merging SE with surface plasmon resonance, KRSE outperforms conventional SE, achieving nanomolar targeting through resonance wavelength shifts (δλ) measurements. Its enhanced interfacial

Femtosecond‐Laser‐Fabricated 3D CYTOP Microfluidic Chips Enabling Super‐Resolution Live Imaging of Cell Behavior in Confined Microspaces

Advanced Materials Technologies, EarlyView.
Using two‐photon polymerization of SU‐8 together with mold processing allowed the creation of defect‐free, flexible 3D microfluidic structures with sub‐micrometer precision in CYTOP. The fabricated CYTOP microfluidic chips enabled super‐resolution imaging of cancer cells in the microchannels, clearly visualizing previously undetectable fine structural ...
