Dumbbell‐Structured Plasmonic‐Enhanced Optical Nanoprobes Boosting Photo‐Magnetic‐Acoustic Multimodal Imaging‐Guided Photodynamic‐Photothermal Synergistic Treatment and Immunogenic Death in Nasopharyngeal Carcinoma

open access: yesAdvanced Science, EarlyView.
This study reports a novel rationally‐designed optical nanoprobe based on dumbbell‐shaped mesoporous silica‐coated gold nanorods, loaded with rare‐earth oxides, photosensitizers, and tumor‐targeted peptides, enabling plasmonic‐enhanced multimodal imaging and PTT‐PDT synergy.

Stability and Bifurcation Analysis of a Predator–Prey Model With Generalized Allee Effect on the Prey Population

open access: yesJournal of Mathematics
This research describes a predator–prey system that takes into account the generalized Allee effect, aiming to derive general conclusions applicable to specific Allee effect functions through the use of a generalized function.

Global stability of the coexistence equilibrium for a general class of models of facultative mutualism [PDF]

open access: yes, 2017
Many models of mutualism have been proposed and studied individually. In this paper, we develop a general class of models of facultative mutualism that covers many of such published models. Using mild assumptions on the growth and self-limiting functions,

Scaling of the risk landscape drives optimal life history strategies and the evolution of grazing [PDF]

open access: yes, 2019
Consumers face numerous risks that can be minimized by incorporating different life-history strategies. How much and when a consumer adds to its energetic reserves or invests in reproduction are key behavioral and physiological adaptations that structure

Impact of Refuge on the Dynamical Behavior of a Tri-Trophic Food Chain Model Under Allee Effect in Prey Species [PDF]

open access: yesEPJ Web of Conferences
The current study focuses on the impact of refuge on the dynamical behaviour of a tri-trophic food chain model under the Allee effect in prey species. The model investigates the asymptotic behaviour of multiple equilibrium points and the influence of the

Stochastic difference equations with the Allee effect

open access: yes, 2016
For a truncated stochastically perturbed equation $x_{n+1}=\max\{ f(x_n)+l\chi_{n+1}, 0 \}$ with $f(x)f(H)>m$. As the amplitude grows, an interval $(m-\varepsilon, m+\delta)$ of initial values arises and expands, such that with a certain probability ...

Dynamical transitions in a pollination--herbivory interaction [PDF]

open access: yes, 2015
Plant-pollinator associations are often seen as purely mutualistic, while in reality they can be more complex. Indeed they may also display a diverse array of antagonistic interactions, such as competition and victim--exploiter interactions.

A Threefold Genetic Allee Effect [PDF]

open access: yesGenetics, 2005
Abstract A decline in population size can lead to the loss of allelic variation, increased inbreeding, and the accumulation of genetic load through drift. We estimated the fitness consequences of these processes in offspring of controlled within-population crosses from 13 populations of the self-incompatible, clonal plant Ranunculus ...

Strategies teachers use to support students' self‐regulation skill development in mainstream primary schools: A scoping review

open access: yesBritish Educational Research Journal, EarlyView.
Abstract This scoping review has explored the interventions and approaches used by teachers in mainstream (general education) primary schools (students aged 4–11) to support self‐regulation skill development in the classroom. The review followed the PRISMA Extension for Scoping Reviews (PRISMA‐ScR) guidelines for reporting and was guided by the Joanna ...

Dynamic behavior of commensal symbiosis system with both feedback control and Allee effect

open access: yes上海师范大学学报. 自然科学版, 2022
The dynamic behavior of commensal symbiosis system with both feedback control and Allee effect is complex. In this paper,the influence of additive Allee effect on the dynamical behavior of the system has been studied based on the feedback control ...
