Taxonomic revision of the Eudicella White, 1839 complex, with description of three new subgenera

Morphological and DNA barcoding analysis of representative taxa in the Eudicella White complex identified five distinct subgenera, three of which are established herein: Eudicella (Coelorrhinella) n. subg., Eudicella (Aneurhina) n. subg., and Eudicella (Ce ...

Reverse-engineering the locomotion of a stem amniote

Auke Ijspeert, Kamilo Andres Melo Becerra, Tomislav Horvat, Konstantinos Karakasiliotis

Reconstructing the locomotion of extinct vertebrates offers insights into their palaeobiology and helps to conceptualize major transitions in vertebrate evolution. However, estimating the locomotor behaviour of a fossil species remains a challenge because ...

Detecting Slipping-Like Perturbations by Using Adaptive Oscillators

Silvestro Micera

This study introduces a novel algorithm to detect unexpected slipping-like perturbations based on the comparison between actual leg joint angles and those predicted by a pool of adaptive oscillators. The approach grounds on the hypothesis that during postu ...

NO binding kinetics in myoglobin investigated by picosecond Fe K-edge absorption spectroscopy

Majed Chergui, Marco Eli Reinhard, Thomas James Penfold, Camelia Borca, Frederico Alves Lima, Mercedes Hannelore Rittmann-Frank, Jochen Rittmann, Mahsa Silatani

Diatomic ligands in hemoproteins and the way they bind to the active center are central to the protein's function. Using picosecond Fe K-edge X-ray absorption spectroscopy, we probe the NO-heme recombination kinetics with direct sensitivity to the Fe-NO bi ...

Identifying the major intermediate species by combining time-resolved X-ray solution scattering and X-ray absorption spectroscopy

Thomas James Penfold

Identifying the intermediate species along a reaction pathway is a first step towards a complete understanding of the reaction mechanism, but often this task is not trivial. There has been a strong on-going debate: which of the three intermediates, the CHI ...

Classification of daily-life postural transitions using trunk-worn wearable barometric pressure sensor

Kamiar Aminian, Anisoara Ionescu, Fabien Massé, Alan Kevin Bourke

Distinguishing sedentary from dynamic behavior is essential in addressing disease conditions that are influenced by mobility. Event-based activity recognition algorithms essentially rely on accurate classification of siting and standing postural transition ...

Distinguishing Sitting and Standing Activities Using a Wearable Barometric Pressure Monitor

Kamiar Aminian, Anisoara Ionescu, Julien Chardonnens, Fabien Massé, Alan Kevin Bourke

Recent advancements in wearable inertial sensor technology have enabled extensive research into activity classification. However, the distinction between the sitting and standing activities using trunk-worn wearable monitoring systems remains challenging, ...

Detection and Classification of Postural Transitions in Real-World Conditions

Kamiar Aminian, Anisoara Ionescu, Raluca Lidia Ganea

This study proposes a new robust classifier for sit-to-stand (SiSt) and stand-to-sit (StSt) detection in daily activity. The monitoring system consists of a single inertial sensor placed on the trunk. By using dynamic time warping, the trunk acceleration p ...

Is There a Size Limit for Cosmopolitan Distribution in Free-Living Microorganisms? A Biogeographical Analysis of Testate Amoebae from Polar Areas

Jiangyan Yang

A long-standing debate in microbial ecology is the extent to which free-living microorganisms exhibit cosmopolitan distributions. We use a comparison of testate amoebae communities in cold "polar" locations (Arctic, Antarctic, and Tibet) to investigate how ...

Morphology, Biometry, and Taxonomy of Freshwater and Marine Interstitial Cyphoderia (Cercozoa: Euglyphida)

Edward Mitchell, Thierry Jean Heger

Good taxonomy is essential for ecological, biogeographical, and evolutionary studies of any group of organisms. Therefore, we performed detailed light- and scanning electron microscopy (SEM) investigations on the shell ultrastructure and biometric analyses ...
