A double inequality for the combination of Toader mean and the arithmetic mean in terms of the contraharmonic mean

Publications de l'Institut Mathematique, 2016
We find the greatest value ? and the least value ? such that the double inequality C(?a +(1-?)b, ?b + (1-?)a) < ?A(a,b) + (1-?)T(a, b)< C(?a + (1-?)b, ?b + (1-?)a) holds for all ? ? (0,1) and a, b > 0 with a ? b, where C(a,b), A(a,b), and T(a,b) denote respectively the contraharmonic, arithmetic, and Toader means of two positive ...

Warm Spring Weather Alters Calling Phenology of Four Sympatric Early‐Breeding Anurans

Integrative Zoology, EarlyView.
An unusually warm March in 2024 (“false spring”) followed by freezing temperatures allowed us to assess the impact of a weather event on an amphibian community. The calling activity of all four species was associated with increasing temperature, and the first date of calling was advanced by 11–18 days.

Geographical Variation in Thermal Adaptation of the Asiatic Toad (Bufo gargarizans)

Integrative Zoology, EarlyView.
Northern and southern populations of Bufo gargarizans exhibit coordinated divergence in thermal preference, resting metabolic rate, and TRPM4 temperature sensitivity along a climatic gradient. ABSTRACT Thermal adaptation in animals can manifest in multiple dimensions, yet few studies have integrated behavioral, physiological, and molecular perspectives

Changes in Site Occupancy of Marsh‐Breeding Frogs Are Associated With Surrounding Land Cover: Implications for Conservation Planning

Animal Conservation, EarlyView.
To help ensure the growth and persistence of frog populations, we quantified changes in frog occurrence as a function of concurrent changes in land cover in the surrounding landscape of eight marsh‐breeding frog species, or groups of species. We used data from the Great Lakes Marsh Monitoring Program delivered by Birds Canada at 377 sites across four ...

Style Brush: Guided Style Transfer for 3D Objects

Computer Graphics Forum, EarlyView.
We introduce Style Brush, a guided 3D style‐transfer method for textured meshes that provides precise creative control. It supports the use of multiple style images, smooth transitions and intuitive guidance, producing visually appealing textures that follow user intent as we demonstrate in our user study and results. Abstract We introduce Style Brush,

Integrated species distribution modeling to assess species status and current and future threats for an imperiled amphibian

Conservation Science and Practice, EarlyView.
To understand the range‐wide drivers of Arizona Toad distribution and anticipate future changes, we combined 13 datasets covering distinct portions of the range in an integrated species distribution model. We estimate that the current occupied range is 1/4–1/3 of previously defined range boundaries and that increasingly dry conditions will lead to ...

Nutritional Stress Modulates Developmental Thresholds in a Male Dimorphic Mite

Entomologia Experimentalis et Applicata, EarlyView.
Global warming can alter nutrition during development, but whether this affects phenotype expression solely through changes in condition or also through developmental decision‐making remains unclear. In the male‐dimorphic bulb mite Rhizoglyphus robini, nutritional stress shifted the developmental threshold for fighter versus scrambler expression and ...

Repurposing Bird Bycatch From Camera Traps in Urban Landscapes: A Correlate of Avian and Mammalian Richness?

Journal of Zoology, EarlyView.
Here, we evaluated the ecological value of bird detections obtained opportunistically from camera traps by comparing them with standardized point count surveys conducted in 2023–2024, across the metropolitan area of Firenze, central Italy, and explored their potential to indicate broader urban biodiversity patterns through cross‐taxa relationships with

Some sharp inequalities for the Toader-Qi mean

, 2015
The Toader-Qi mean of positive numbers $a$ and $b$ defined by \begin{equation*} TQ\left( a,b\right) =\frac{2}{π}\int_{0}^{π/2}a^{\cos ^{2}θ}b^{\sin ^{2}θ}dθ\end{equation*} is related to the modified Bessel function of the first kind. In this paper, we present several properties of this mean, and establish some sharp inequalities for this mean in terms ...

The Effect of Digitalisation and Corruption on Human Development in Sub‐Sahara Africa: Are There Regional Differences?

South African Journal of Economics, Volume 94, Issue 4, December 2026.
ABSTRACT The study explores the effect of digitalisation on corruption and on human development in Sub‐Sahara Africa (SSA) and its subregions. The fixed effects and Hausman–Taylor techniques and data for 33 SSA countries are used. We find that digitalisation has a nonlinear effect on corruption and on human development.
