Sharp inequalities for Toader mean in terms of other bivariate means

Hacettepe Journal of Mathematics and Statistics, 2023
In the paper, the author discovers the best constants $\alpha_1$, $\alpha_2$, $\alpha_3$, $\beta_1$, $\beta_2$ and $\beta_3$ for the double inequalities \[ \alpha_1 A\left(\frac{a-b}{a+b}\right)^{2n+2} < T(a,b)-\frac{1}{4}C-\frac{3}{4}A-A\sum_{k=1}^{n-1}\frac{(\frac{1}{2},k)^2}{4((k+1)!)^2}\left(\frac{a-b}{a+b}\right)^{2k+2}<\beta_1 A ...

Optimal Lehmer mean bounds for the $n$th power-type Toader means of n=-1,1,3

Journal of Mathematical Inequalities, 2022
Summary: We prove that \(\lambda_1=0\), \(\mu_1=5/8\), \(\lambda_2=-1/8\), \(\mu_2=0\), \(\lambda_3=-1\) and \(\mu_3 = -7/8\) are the best possible parameters such that the double inequalities \[ \begin{aligned} L_{\lambda_1}(a, b) < T_3(a, b) < L_{\mu_1}(a, b),\\ L_{\lambda_2}(a, b) < T_1(a, b) < L_{\mu_2}(a, b),\\ L_{\lambda_3}(a, b) < T_{-1}(a, b) <

Talk to Me Like a Human: How AI Chatbot Message Tone, Recommendation Type, and Personalization Drive Consumers' Continuance Intention

Journal of Consumer Behaviour, EarlyView.
ABSTRACT This study investigates how artificial intelligence (AI) chatbot message tone, fashion product recommendation type, and personalization level interact to shape consumers' continuance intention in online fashion shopping. Building on Construal Level Theory and the Stereotype Content Model, we treat warmth and competence cues as psychological ...

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Higher Energy Demands and Lower Body Condition in a Hot Spring: Comparing Relict Leopard Frogs at Two Thermally Contrasting Sites

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Following range‐wide decline, all remnant populations of the relict leopard frog (Rana onca) in the eastern Mojave Desert of the southwestern USA occupied geothermally influenced hot springs. In recent years, however, several large populations have been established at cold‐water sites.

Viability analysis and the importance of fine‐scale variables influencing roadkills of a toad population

The Journal of Wildlife Management, EarlyView.
Fine‐scale population variables better explain roadkill patterns in natterjack toads (Epidalea calamita) than habitat proxies, with mortality driven mainly by local abundance, reduced by roadside embankments, and decreasing as the season advanced. Despite high roadkills, population viability analyses indicate no immediate extinction risk under current ...

A new chain of inequalities involving the Toader-Qi, logarithmic and exponential means

Applicable Analysis and Discrete Mathematics, 2021
In this paper, we establish an interesting chain of sharp inequalities involving Toader-Qi mean, exponential mean, logarithmic mean, arithmetic mean and geometric mean. This greatly improves some existing results.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Ranavirus risk depends on host community characteristics more than the presence of Batrachochytrium dendrobatidis

Oikos, EarlyView.
Novel parasite introductions are threatening wildlife communities globally. The degree of threat depends on the ecological context, namely host community characteristics and the presence of other parasites. How these two factors interact to shape the outcomes of parasite introductions is not known. We experimentally investigated how infection following

More than proteins for empty stomachs: Wild meat in the BaTonga food system

People and Nature, EarlyView.
Abstract Our paper highlights the limitations of the framework used by many conservation‐focused programmes that incorporate food security objectives. This framework encourages the substitution of wild proteins with domestic proteins by promoting animal farming in communities located near conservation areas.
