Robust Multi-Target Localization in ISAC Systems: Leveraging Multidimensional Scaling

open access: yesIEEE Open Journal of the Communications Society
Localization for multi-target systems (MTS) in anchor-free scenarios is receiving increasing attention, particularly for MTS, such as the Internet of Vehicles and swarms.

Geometric morphometric comparison of three populations of Mesopotamian minnow (Barilius mesopotamicus Berg, 1932) in Jarrahi River basin [PDF]

open access: yesبوم‌شناسی آبزیان, 2019
The present study compared the geometric morphometrics of Barilius mesopotamicus populations, one of the native cyprinids in Jarrahi River basin. For this purpose, 166 fish specimens from three populations of Aalaa, Zardmashin, and main Jarrahi rivers ...

Ontogeny of murine bony semicircular canal form

open access: yesThe Anatomical Record, EarlyView.
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Comparing the semantic structures of lexicon of Mandarin and English

open access: yesLanguage and Cognition
This paper presents a cross-language study of lexical semantics within the framework of distributional semantics. We used a wide range of predefined semantic categories in Mandarin and English and compared the clusterings of these categories using ...

In-the-wild Facial Expression Recognition in Extreme Poses

open access: yes, 2018
In the computer research area, facial expression recognition is a hot research problem. Recent years, the research has moved from the lab environment to in-the-wild circumstances. It is challenging, especially under extreme poses.

Oblique Procrustes Rotations in Factor Analysis [PDF]

open access: yesSIAM Journal on Scientific and Statistical Computing, 1984
An iterative procedure is presented for the so-called Procrustes problem in the case when only some of the weights are one and the rest are zero. Instead of the Newton method, the paper uses the Lagrange multipliers.

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

Larger Lumbar Vertebral Body Osteophyte Volume Is Associated With Older Age and a More Caudal Vertebral Level in Individuals With Chronic Low Back Pain. [PDF]

open access: yesJOR Spine
Procrustes analysis was used to match osteophyte‐free lumbar vertebral bodies to lumbar vertebral bodies containing osteophytes. The volume of the reference library bone was subtracted to create an osteophyte model, from which regional osteophyte volumes were calculated.

Intra- and Interspecific Interactions as Proximate Determinants of Sexual Dimorphism and Allometric Trajectories in the Bottlenose Dolphin Tursiops truncatus (Cetacea, Odontoceti, Delphinidae). [PDF]

open access: yesPLoS ONE, 2016
Feeding adaptation, social behaviour, and interspecific interactions related to sexual dimorphism and allometric growth are particularly challenging to be investigated in the high sexual monomorphic Delphinidae.

2D shape classification and retrieval [PDF]

open access: yes, 2005
We present a novel correspondence-based technique for efficient shape classification and retrieval. Shape boundaries are described by a set of (ad hoc) equally spaced points – avoiding the need to extract “landmark points”.
