Different shape but the same topographical complexity—The lingual gross anatomy of the Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract Despite the distinctly different shapes of their tongues, the tongue gross anatomy of Saimaa ringed seal closely resembled that of Baltic ringed seal. There were no differences in the extrinsic and intrinsic tongue muscles or their associated vascularization and innervation between Saimaa and Baltic ringed seals.

Joint power control and user grouping mechanism for efficient uplink non‐orthogonal multiple access‐based 5G communication: Utilising the Lèvy‐flight firefly algorithm

IET Networks, EarlyView., 2023
We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

Prediction of Large Whale Distributions: A Comparison of Presence–Absence and Presence-Only Modeling Techniques

Frontiers in Marine Science, 2018
Species distribution models that predict species occurrence or density by quantifying relationships with environmental variables are used for a variety of scientific investigations and management applications. For endangered species, such as large whales,

Analysis of turbulence and vortex structures by flow mapping [PDF]

, 1997
The technique of Particle Image Velocimetry (PIV) flow mapping is reviewed and comparisons made with Laser Doppler Anemometry (LDA). Results are presented showing the application of PlV to the determination of coherent structures in grid-generated ...

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Tourism informing conservation: The distribution of four dolphin species varies with calf presence and increases their vulnerability to vessel traffic in the four‐island region of Maui, Hawai‘i

Ecological Solutions and Evidence, 2021
We need reliable information about the spatial and temporal distribution of mobile species to effectively manage anthropogenic impacts to which they are exposed.

Placental crises: disruptive selection and maternal under‐investment as the foundations of mammalian placental evolution and dysfunction

Biological Reviews, EarlyView.
ABSTRACT Among the vertebrates, mammals are notable for the dominance of live birth and placental nutrition. The structural diversity of the mammalian placenta is remarkable, despite sharing a single common ancestor and conserved physiological functions.

ORCA-SPOT: An Automatic Killer Whale Sound Detection Toolkit Using Deep Learning [PDF]

, 2019
Large bioacoustic archives of wild animals are an important source to identify reappearing communication patterns, which can then be related to recurring behavioral patterns to advance the current understanding of intra-specific communication of non ...
