Dental crown morphological variation and heterodonty in carcharhiniform sharks

open access: yesThe Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

A gap in the Pliocene invasion of seawater to the Gulf of California

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
The Proto-Gulf extensional province was formed during the Miocene, from 14 to 12 Ma. During the main extensional period, within the Baja California central domain, several depocenters were formed including the El Boleo basin, followed to the south by ...

The P-wave upper mantle structure beneath an active spreading centre: the Gulf of California [PDF]

open access: yesGeophysical Journal International, 1984
Detailed analysis of short period travel time, and waveform data reveals the upper mantle structure beneath an oceanic ridge to depths of 900 km. More than 1400 digital seismograms from earthquakes in Mexico and central America recorded at SCARLET yield 1753 travel times and 58 direct measurements of short period travel time as well as high quality ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

open access: yesBiological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Water exchange between the Gulf of California and the Pacific Ocean: results from a one-year global HYCOM simulation

open access: yesGeofísica Internacional
The mean and seasonal water exchange between the gulf of California and the Pacific Ocean (PO) are analyzed with a one-year global HYCOM simulation. At the mouth of the gulf there are six alternating layers of inflow and outflow of mean transport with ...

New Insights Into the Anconeus Epitrochlearis Muscle and Its Relationship to the Ulnar Nerve: Anatomical Study

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Ulnar neuropathy due to compression at the cubital tunnel is common. However, our understanding of the relationships between this type of nerve compression and the variant anconeus epitrochlearis muscle (AEM) is poorly understood. Therefore, the present anatomical study was performed to better elucidate these relationships.

Porous Carbon Materials for Carbon Dioxide Capture

open access: yesCarbon Energy, EarlyView.
This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
