Optimal convex combination bounds of Seiffert and geometric means for the arithmetic mean [PDF]

Journal of Mathematical Inequalities, 2011
We find the greatest value α and the least value β such that the double inequality αT (a,b) + (1−α)G(a,b) 0 with a = b . Here T (a,b) , G(a,b) , and A(a,b) denote the Seiffert, geometric, and arithmetic means of two positive numbers a and b , respectively.

Non‐Carious Cervical Lesions in Wild Primates: Implications for Understanding Toothpick Grooves and Abfraction Lesions

American Journal of Biological Anthropology, Volume 188, Issue 2, October 2025.
ABSTRACT Objectives In clinical settings, non‐carious cervical lesions (NCCLs) are often linked to abrasion, erosion, abfraction, or a combination of these factors. In archaeological and paleontological remains, the most common NCCL is the “toothpick groove,” yet little is known about the occurrence of these and other NCCLs in wild non‐human primates ...

Axial Ratio of Edge-On Spiral Galaxies as a Test For Extended Bright Radio Halos

, 2015
We use surface brightness contour maps of nearby edge-on spiral galaxies to determine whether extended bright radio halos are common. In particular, we test a recent model of the spatial structure of the diffuse radio continuum by Subrahmanyan and Cowsik

Guidelines for Emergency Management of Traumatic Dental Injuries of the Chilean Ministry of Health

Clinical and Public Health Guidelines, Volume 2, Issue 4, October 2025.
ABSTRACT Background Traumatic dental injuries (TDIs) are the fifth most prevalent condition worldwide. Proper diagnosis and emergency management are essential for ensuring a favourable outcome and prognosis. Although other international guidelines provide recommendations for the emergency management of TDI, specific clinical situations are not always ...

Identification and characterization of a novel extracellular matrix protein nephronectin that is associated with integrin alpha8beta1 in the embryonic kidney. [PDF]

, 2001
The epithelial-mesenchymal interactions required for kidney organogenesis are disrupted in mice lacking the integrin alpha8beta1. None of this integrin's known ligands, however, appears to account for this phenotype. To identify a more relevant ligand, a

Combined Evidence Reveals the Origin of a Rapid Range Expansion Despite Retained Genetic Diversity and a Weak Founder Effect

Molecular Ecology, Volume 34, Issue 19, October 2025.
ABSTRACT Many species are currently experiencing range shifts in response to changing environmental conditions with potentially serious genetic consequences. Repeated founder events and strong genetic drift are expected to erode genetic variation at the range front, reducing adaptive potential and slowing or even halting the expansion.

On the p-Version of the Schwab-Borchardt Mean

International Journal of Mathematics and Mathematical Sciences, 2014
This paper deals with a one-parameter generalization of the Schwab-Borchardt mean. The new mean is defined in terms of the inverse functions of the generalized trigonometric and generalized hyperbolic functions.

Evolutionary systematics of the Staphylininae rove beetles (Coleoptera: Staphylinidae) resolved by integration of phylogenomics, comparative morphology and historical biogeography

Systematic Entomology, Volume 50, Issue 4, Page 750-779, October 2025.
Higher classification of the rove beetle subfamily Staphylininae is revised based on novel phylogenomic, morphological and biogeographic evidence. Four new subtribes are described for Staphylininae; of them, two are for the tribe Tanygnathinini and two are for the tribe Staphylinini, and both tribes changed in composition due to other novelties ...

Functional Differences Between SIRPα Splice Isoforms

Genes to Cells, Volume 30, Issue 5, September 2025.
SIRPα is expressed in phagocytic cells, and when it recognizes CD47, “don't eat me” signal, it suppresses phagocytosis. We show here that short SIRPα, a less‐studied splice isoform, has a different function from a well‐studied long SIRPα. Short SIRPα may act as a “don't eat me” signal regulator.
