Abstract:

During the Neogene and the Quaternary, African suids show dental morphological changes considered to reflect adaptations to increasing specialization on graminivorous diets, notably in the genus <em>Kolpochoerus </em>van Hoepen & van Hoepen, 1932. They tend to exhibit elongated third molars and some degree of hypsodonty, suggesting increasing consumption of abrasive grasses. However, the most significant morphological changes are observed more than 1 million years after the increased consumption of C4 plants, such as graminoids. To date, only a few studies have applied dental microwear tex

Based on fractal geometry theory and surface roughness characterization technology, this paper presents the fractal characterization of nonuniform corrosion degree of corroded reinforcing steel bars. The surface profile curves of different corroded reinforcing steel bars were obtained and their fractal dimensions were calculated in order to describe the fractal characteristics. As is shown by the results, the surface profile curves of rebar have statistical fractal feature. However, fractal dimension is not sensitive to small changes in profile curves.

AbstractBiomimetic hierarchical surface structures that exhibit features having multiple length scales have been used in many technological and engineering applications.

Abstract:

Scale-sensitive fractal analysis of high-resolution 3-dimensional surface reconstructions of wear patterns has advanced our knowledge in evolutionary biology, and has opened up opportunities for translatory applications in clinical practice. To elucidate the microwear characteristics of attrition and erosion in worn natural teeth, we scanned 50 extracted human teeth using a confocal profiler at a high optical resolution (X–Y, 0.17 µm; Z < 3 nm). Our hypothesis was that microwear complexity would be greater in erosion and that anisotropy would be greater in attrition. The teeth were divided

Abstract:

The Katz fractal dimension (KFD) is an effective nonlinear dynamic metric that characterizes the complexity of time series by calculating the distance between two consecutive points and has seen widespread applications across numerous fields. However, KFD is limited to depicting the complexity of information from a single scale and ignores the information buried under different scales. To tackle this limitation, we proposed the variable-step multiscale KFD (VSMKFD) by introducing a variable-step multiscale process in KFD. The proposed VSMKFD overcomes the disadvantage that the traditional coar

A rescaled range analysis was performed to determine the Hurst exponent of the velocity time series, for simulations of cells rolling on either a uniform or punctate distribution of P-selectin molecules.

Dental microwear texture analysis (DMTA) quantifies microscopic scar or wear patterns left on teeth by different foods or extraneous ingested items such as grit.

Abstract:

ABSTRACTA 3D phase scanning method was applied to study blood plasma facies, generating layered polarization maps of the object field. The most sensitive parameters to changes in birefringence distribution were identified. Multifractal analysis using wavelet transforms and fractal dimension spectra provided specific insights into the scale self‐similarity of the polarization maps. The multifractal spectra of ellipticity distributions were algorithmically derived, revealing that the third‐ and fourth‐order statistical moments were most sensitive to changes in the supramolecular networks of the

Abstract:

ABSTRACTAn analysis of RMC structure models of ion conducting glasses in terms of our bond softness sensitive bond-valence method enables us to identify the conduction pathways for a mobile ion as regions of sufficiently low valence mismatch. The strong correlation between the volume fraction F of the “infinite pathway cluster” and the transport properties yields a prediction of both the absolute value and activation energy of the dc ionic conductivities directly from the structural models. Separate correlations for various types of mobile cations can be unified by employing the square root of

Abstract:

AbstractWith the help of a physically based recharge‐groundwater flow model and robust detrended fluctuation analysis (r‐DFAn), the effect of local (catchment‐scale) forcing on groundwater levels' scaling behaviour in a riparian aquifer in Wallingford, UK, is investigated. The local forcings investigated in this study include the rainfall's temporal scaling behaviour (which is simulated by changing rainfall's intermittency parameter in a β‐lognormal multiplicative random cascade model), the aquifer's physical parameters (saturated hydraulic conductivity, specific yield, the empirical coefficie

Abstract:

AbstractLate Pliocene Procynocephalus subhimalayanus from the Upper Siwaliks, India is known from only three specimens. The dietary proclivities of this taxon have implications for reconstructing the paleoecology of the Upper Siwaliks. The dental microwear texture properties of Procynocephalus are compared to those from extant tropical forest primates including Alouatta palliata (n = 11), Cebus apella (n = 13), Gorilla gorilla (n = 9), Lophocebus albigena (n = 15) and Trachypithecus cristatus (n = 12). Dental microwear textures are generated by scanning the surface enamel of Facet 9 using whit

Abstract:

Abstract Background The chlorophyll content is a vital indicator for reflecting the photosynthesis ability of plants and it plays a significant role in monitoring the general health of plants. Since the chlorophyll content and the soil–plant analysis development (SPAD) value are positively correlated, it is feasible to predict the SPAD value by calculating the vegetation indices (VIs) through hyperspectral images, thereby evaluating the severity of plant diseases. However, current indices simply adopt few wavelengths of the hyperspectral information, which may decrease the prediction accuracy.

Abstract:

AbstractHere, we present and synthesise some recent collaborative efforts in our laboratories to establish protocols for using dental microwear texture analysis, originally developed to reconstruct diets of fossil mammals and to aid in the clinical assessment of dental patients today. The idea is to propose a method where polyvinylsiloxane impressions, as used in many dental practices, can be combined with surface texture analysis for a rapid, non‐invasive, and inexpensive approach to detect and monitor the progression of tooth wear at fine scales over short durations and help determine causal

Abstract Few living mammals are as exemplary of a semiaquatic lifestyle as otters, exhibiting a diverse array of ways that an animal can use water and land resources similar to the way other clades, such as cetaceans or pinnipeds, may have used their habitats during the transition from terrestrial to aquatic life. Otters (subfamily Lutrinae of the Mustelidae) are known to differ greatly in their diets between species and even within individuals depending on seasons, often differing largely in proportions of fishes versus crabs and echinoderms. Such diets including or excluding hard objects lik

IntroductionSince its reform and opening up, China’s new urbanization strategy, which provides institutional support for the optimization of the spatial form of tourism towns, has made remarkable progress and demonstrated great potential. In this study, the urban area of Wulingyuan District, China, a Natural World Heritage Site, is taken as the research object.MethodsBased on Landsat remote sensing images at five time nodes between 2000 and 2022, the spatial and temporal characteristics and evolutionary patterns of urban expansion in Wulingyuan are quantitatively investigated and the driving f
