Boundedness of the Marcinkiewicz integrals with rough kernel associated to surfaces

open access: yesTohoku Mathematical Journal, 2010
In this paper, the authors discuss the weighted $L^p$ boundedness for the rough Marcinkiewicz integrals associated to surfaces. More precisely, the kernel of our operator lacks smoothness not only on the unit sphere, but also in the radial directions.

Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho

Variability of jaw muscles in Tunisian street dogs and adaptation to skull shape

open access: yesThe Anatomical Record, EarlyView.
Abstract The impact of artificial selection on the masticatory apparatus of dogs has been poorly studied, and comparative data with dogs subjected to more natural constraints are lacking. This study explores the jaw musculature of Tunisian street dogs, which are largely free from the influence of breed‐specific selection.

A note on multilinear singular integrals with rough kernel

open access: yesAnalysis in Theory and Applications, 2004
In this paper, the author gives the weighted weak Lipschitz boundedness with power weight for rough multilinear integral operators. A simple way is obtained that is closely linked with a class of rough fractional integral operators.

Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

open access: yesThe Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

Comprehensive modeling of far-infrared drying process for rough rice in a combined FIR dryer

open access: yesDiscover Food
This study introduces a novel single-parameter model for the far-infrared (FIR) drying process of rough rice in a combined FIR dryer, aiming to streamline the prediction process and enhance its efficiency.

Multi‐Century Grindstone Quarrying at Brumby Yard, Queensland

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT The timing and duration of prehistoric quarrying is poorly understood within Australia, with limited ages available for quarries owing to the difficulties in dating these rock‐sediment constructions. We report the first multi‐sample, optically stimulated luminescence ages from quarry pits in Brumby Yard, an Aboriginal grindstone quarry ...

Dendroglyphs, Pictographs and Social Identity in the Wet Tropics Rainforest of Northeastern Australia

open access: yesArchaeology in Oceania, EarlyView.
ABSTRACT This research examines rock art and dendroglyphs in the Wet Tropics of northeast Australia to investigate their relationship to linguistic social identity. The region was selected for its complex socio‐cultural landscape, marked by a diversity of languages in a distinct, relatively small area.

Lp bounds for rough parabolic maximal operators

open access: yesHeliyon, 2020
In this article, we establish the Lp estimates for a certain class of rough parabolic maximal functions related to surfaces of revolution. The obtained estimates allow us to apply an extrapolation argument to extend and improve some previously known ...
