BACKGROUND: Motor variability has been related to motor control playing a functional role in human adaptive behaviours. However, the direction of the relationship between variability and motor control can be unclear. The specific relations that exist between task constraints and movement (re)organization could explain some of this controversy. RESEARCH QUESTION: This study sought to understand whether manipulation of task constraints result in changes in the magnitude or structure of motor system variability observed in a basic walking task...

The surface coating of metal oxide nanoparticles using biopolymer chitosan has evolved to become an important area of polymer nanotechnology. Herein, we report the preparation of chitosan coated zinc oxide (CS-ZnO) nanocomposite for the first time by a green chemistry approach using bioflavonoid rutin. The formation of CS-ZnO nanocomposite was preliminarily confirmed by color change and UV-Visible spectroscopy. FE-SEM images revealed agglomeration of CS-ZnO nanocomposite having predominant rod shaped structure...

OBJECTIVES: Lower limb diaphyseal geometry is often used to evaluate mobility in past populations. Diaphyseal dimensions such as high shape (IX /IY ) indices generally thought to reflect high mobility may also result from walking over rough terrain. This study investigates the possible effects of terrain on lower limb diaphyseal cross-sectional geometric dimensions. MATERIALS: The sample (N = 3,195) comprises adult skeletons from Europe, Africa, North America, and Asia, spanning from around 30,000 BP to mid-twentieth century...

Modern chromatographic data acquisition software often behave as black boxes where the researchers have little control over the raw data processing. One of the significant interests of separation scientists is to extract physico-chemical information from chromatographic experiments and peak parameters. In addition, column developers need the total peak shape analysis to characterize the flow profile in chromatographic beds. Statistical moments offer a robust approach for providing detailed information for peaks in terms of area, its center of gravity, variance, resolution, and its skew without assuming any peak model or shape...

This study demonstrates sexual dimorphism in feline bones based on morphometric analysis of dried flat bones (scapula and os coxa) and long bones (humerus, radius, ulna, femur, tibia, and fibula) of 92 felines (50 male, 42 female). A total of 58 parameters (flat bones: scapula = 4 and os coxa = 7; long bones: humerus = 8, radius = 9, ulna = 10, femur = 9, tibia = 7, and fibula = 4) were measured using a digital vernier caliper. Twenty-three parameters were found to be significantly different between cats of different sexes and skull shapes...

Application of the Luttinger theorem to the Kondo lattice YbRh2 Si2 suggests that its large 4f-derived Fermi surface (FS) in the paramagnetic (PM) regime should be similar in shape and volume to that of the divalent local-moment antiferromagnet (AFM) EuRh2 Si2 in its PM regime. Here we show by angle-resolved photoemission spectroscopy that paramagnetic EuRh2 Si2 has a large FS essentially similar to the one seen in YbRh2 Si2 down to 1 K. In EuRh2 Si2 the onset of AFM order below 24.5 K induces an extensive fragmentation of the FS due to Brillouin zone folding, intersection and resulting hybridization of the Fermi-surface sheets...

This paper reports the results of analysis of the electrical double layer (EDL) phenomenon in molten salts to provide information on the influence of short range interaction type on the shape of charge distribution and the effect of the charge distribution shape on capacitance values. A new method of analysis is proposed, which allows a quantitative discussion. It is assumed that EDL can be modelled as a number of capacitor plates connected in series. This paper reports the application of the proposed method in quantitative analysis of the molten salt capacitance data obtained for different short range potentials...

Primary microplastics have been collected from 17 beaches along the Atlantic, English Channel and southern North Sea coasts of western Europe. Based on visual characteristics, these plastics were differentiated as either relatively smooth, lentil- or disc-shaped pre-production pellets (or nurdles), which were usually a few mm in diameter and were mainly white to off-white, or rougher and more irregular pellets that were slightly larger and usually black. The latter appeared to be bio-beads, or plastics that are specifically manufactured for use as biomedia in certain sewage water treatment (SWT) plants and, possibly, in other industrial wastewater treatment applications...

Collagen hydrolysates are dietary supplements used for nutritional and medical purposes. They are complex mixtures of low-molecular-weight peptides obtained from the enzymatic hydrolysis of collagen, which provide intrinsic batch-to-batch heterogeneity. In consequence, the quality of these products, which is related to the reproducibility of their mass distribution pattern, should be addressed. Here, we propose an analytical approach to determine the peptide pattern as a quality attribute of Colagenart®, a product containing collagen hydrolysate...

James D Englehardt, Weihsueh A Chiu
Current efforts to assess human health response to chemicals based on high-throughput in vitro assay data on intra-cellular changes have been hindered for some illnesses by lack of information on higher-level extracellular, inter-organ, and organism-level interactions. However, a dose-response function (DRF), informed by various levels of information including apical health response, can represent a template for convergent top-down, bottom-up analysis. In this paper, a general DRF for chronic chemical and other health stressors and mixtures is derived based on a general first-order model previously derived and demonstrated for illness progression...

Whole-brain recordings give us a global perspective of the brain in action. In this study, we describe a method using light field microscopy to record near-whole brain calcium and voltage activity at high speed in behaving adult flies. We first obtained global activity maps for various stimuli and behaviors. Notably, we found that brain activity increased on a global scale when the fly walked but not when it groomed. This global increase with walking was particularly strong in dopamine neurons, which showed little activity otherwise...

The purpose of this study was to examine relationships between food security, parental health behaviors, and overweight/obesity among 2- to 5-year-old children in West Tennessee (N = 264). Results from logistic regression models indicate that the association between parental characteristics and child weight status varies by child sex and household food security. These findings highlight the need for more nuanced analysis that can produce results that inform and shape the development of precise health promotion and intervention strategies designed for diverse low-resource populations...

The reader can be excused for not recognizing, in the Comment by Meirovitch et al., the paper that I wrote. Much of the emphasis is on topics not touched upon by me, and attributes to me statements that I did not make; and never would make. In view of this misrepresentation, it is useful first to describe what my paper actually is about. I identify a very clear and serious error in the paper entitled "Analysis of Protein-Lipid Interactions Based on Model Simulations of ESR." by Meirovitch et al. (referred to as MNF)...

This work investigates the preparation of a magnetically recoverable photocatalytic nanocomposite of maghemite nanoparticles coated with silica and carbon doped titanium dioxide. The novel nanocomposite boasts the advantages of efficient photocatalytic degradation of organic pollutants in water and ease of recovery of the fine particles after water treatment. The photocatalytic nanocomposite was successfully synthesized through a stepwise approach via co-precipitation and sol-gel methods. Characterisation by Fourier transform infrared (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS) substantiated the existence of the intended structure of the nanocomposite and the particles were found to be in the size range of 15-22 nm with a quasi-spherical shape...
