Age-Related Changes of the Anticipatory Postural Adjustments During Gait Initiation Preceded by Vibration of Lower Leg Muscles

Gait initiation (GI) challenges the balance control system, especially in the elderly. To date, however, there is no consensus about the age effect on the anticipatory postural adjustments (APAs). There is also a lack of research on APAs in older adults after proprioceptive perturbation in the sagittal plane. This study aimed to compare the ability of young and older participants to generate APAs in response to the vibratory-induced perturbation delivered immediately before GI. Twenty-two young and 22 older adults performed a series of GI trials: (1) without previous vibration; (2) preceded by the vibration of triceps surae muscles; and (3) preceded by the vibration of tibialis anterior muscles. The APAs magnitude, velocity, time-to-peak, and duration were extracted from the center of pressure displacement in the sagittal plane. Young participants significantly modified their APAs during GI, whereas older adults did not markedly change their APAs when the body vertical was shifted neither backward nor forward. Significant age-related declines in APAs were observed also regardless of the altered proprioception.The results show that young adults actively responded to the altered proprioception from lower leg muscles and sensitively scaled APAs according to the actual position of the body verticality. Contrary, older adults were unable to adjust their postural responses indicating that the challenging transition from standing to walking probably requires higher reliance on the visual input. The understanding of age-related differences in APAs may help to design training programs for the elderly specifically targeted to improve balance control in different sensory conditions, particularly during gait initiation.
Muscle Activation in Older Females after a Community-Based Resistance Training Program: A Pilot Study

Many randomized controlled trials utilizing resistance training have shown improvements in muscle activation in older adults. However, these programs lack applicability to community-dwelling older adults due to several challenges. Therefore, the purpose of this study was to test the effects of an eight-week community-based resistance training program on muscle activation in older adults. Eight females (age: 61 ± 4 years, body mass index (BMI): 31.7 ± 5.7 kg/m2) were enrolled in the study. The surface electromyography (sEMG) activity was evaluated before and after training for three muscles (biceps brachii, upper trapezius, and rectus femoris). Additional weight load tests were performed to measure muscle activation in response to the added resistance. After eight weeks of training, no changes were observed in muscle activation for biceps brachii and upper trapezius but was decreased for rectus femoris (p = 0.04). Furthermore, in response to weight loads, biceps brachii and upper trapezius improved muscle activation after training. In summary, eight weeks of community-based resistance training program non-significantly improved the activation of upper-body muscles in older adults.
A Taxonomy of Food Supply Chain Problems from a Computational Intelligence Perspective

In the last few years, the Internet of Things, and other enabling technologies, have been progressively used for digitizing Food Supply Chains (FSC). These and other digitalization-enabling technologies are generating a massive amount of data with enormous potential to manage supply chains more efficiently and sustainably. Nevertheless, the intricate patterns and complexity embedded in large volumes of data present a challenge for systematic human expert analysis. In such a data-driven context, Computational Intelligence (CI) has achieved significant momentum to analyze, mine, and extract the underlying data information, or solve complex optimization problems, striking a balance between productive efficiency and sustainability of food supply systems. Although some recent studies have sorted the CI literature in this field, they are mainly oriented towards a single family of CI methods (a group of methods that share common characteristics) and review their application in specific FSC stages. As such, there is a gap in identifying and classifying FSC problems from a broader perspective, encompassing the various families of CI methods that can be applied in different stages (from production to retailing) and identifying the problems that arise in these stages from a CI perspective. This paper presents a new and comprehensive taxonomy of FSC problems (associated with agriculture, fish farming, and livestock) from a CI approach; that is, it defines FSC problems (from production to retail) and categorizes them based on how they can be modeled from a CI point of view. Furthermore, we review the CI approaches that are more commonly used in each stage of the FSC and in their corresponding categories of problems. We also introduce a set of guidelines to help FSC researchers and practitioners to decide on suitable families of methods when addressing any particular problems they might encounter. Finally, based on the proposed taxonomy, we identify and discuss challenges and research opportunities that the community should explore to enhance the contributions that CI can bring to the digitization of the FSC.
Geodynamic evolution of a wide plate boundary in the Western Mediterranean, near-field versus far-field interactions

The present-day tectonic setting of the Western Mediterranean region, from the Pyrénées to the Betics and from the Alps to the Atlas, results from a complex 3-D geodynamic evolution involving the interactions between the Africa, Eurasia and Iberia plates and asthenospheric mantle dynamics underneath. In this paper, we review the main tectonic events recorded in this region since the Early Cretaceous and discuss the respective effects of far-field and near-field contributions, in order to unravel the origin of forces controlling crustal deformation. The respective contributions of mantle-scale, plate-scale and local processes in the succession of tectonic stages are discussed. Three periods can be distinguished: (1) the first period (Tethyan Tectonics), from 110 to 35 Ma, spans the main evolution of the Pyrenean orogen and the early evolution of the Betics, from rifting to maximum shortening. The rifting between Iberia and Europe and the subsequent progressive formation of new compressional plate boundaries in the Pyrénées and the Betics, as well as the compression recorded all the way to the North Sea, are placed in the large-scale framework of the African and Eurasian plates carried by large-scale mantle convection; (2) the second period (Mediterranean Tectonics), from 32 to 8 Ma, corresponds to a first-order change in subduction dynamics. It is most typically Mediterranean with a dominant contribution of slab retreat and associated mantle flow in crustal deformation. Mountain building and back-arc basin opening are controlled by retreating and tearing slabs and associated mantle flow at depth. The 3-D interactions between the different pieces of retreating slabs are complex and the crust accommodates the mantle flow underneath in various ways, including the formation of metamorphic core complexes and transfer fault zones; (3) the third period (Late-Mediterranean Tectonics) runs from 8 Ma to the Present. It corresponds to a new drastic change in the tectonic regime characterized by the resumption of N-S compression along the southern plate boundary and a propagation of compression toward the north. The respective effects of stress transmission through the lithospheric stress-guide and lithosphere-asthenosphere interactions are discussed throughout this period.
Magnetically-Induced Pressure Generation in Magnetorheological Fluids under the Influence of Magnetic Fields

This study aims to observe the magnitude of the Magnetorheological Fluids (MRFs) pressure due to the application of a magnetic field. This was accomplished by placing the MRFs in a U-shaped tube, then applying a magnetic field generated by a magnetic coil. A finite element simulation for the magnetic field was carried out to estimate the magnetic field strength generated by the coil variable to the current input given in the simulated apparatus. Changes in MRFs pressure were recorded using a data logger to better observe the fluid pressure phenomena occurring in the MRFs with respect to current input variations. The results showed that the magnetic field influences the MRFs fluid pressure proportionally. The slope is not constant as the magnetic field effect to the fluid pressure gets stronger when the current input is higher. However, there are also an adverse effect of heat generated in the coil in higher current, which results in coil performance degradation and reduces the magnetic field strength.
Antimicrobial and Anticancer Application of Silver(I) Dipeptide Complexes

Three silver(I) dipeptide complexes [Ag(GlyGly)]n(NO3)n (AgGlyGly), [Ag2(GlyAla)(NO3)2]n (AgGlyAla) and [Ag2(HGlyAsp)(NO3)]n (AgGlyAsp) were prepared, investigated and characterized by vibrational spectroscopy (mid-IR), elemental and thermogravimetric analysis and mass spectrometry. For AgGlyGly, X-ray crystallography was also performed. Their stability in biological testing media was verified by time-dependent NMR measurements. Their in vitro antimicrobial activity was evaluated against selected pathogenic microorganisms. Moreover, the influence of silver(I) dipeptide complexes on microbial film formation was described. Further, the cytotoxicity of the complexes against selected cancer cells (BLM, MDA-MB-231, HeLa, HCT116, MCF-7 and Jurkat) and fibroblasts (BJ-5ta) using a colorimetric MTS assay was tested, and the selectivity index (SI) was identified. The mechanism of action of Ag(I) dipeptide complexes was elucidated and discussed by the study in terms of their binding affinity toward the CT DNA, the ability to cleave the DNA and the ability to influence numbers of cells within each cell cycle phase. The new silver(I) dipeptide complexes are able to bind into DNA by noncovalent interaction, and the topoisomerase I inhibition study showed that the studied complexes inhibit its activity at a concentration of 15 μM.
The moderating effects of mindfulness facets on psychological distress and emotional eating behaviour

BACKGROUND Emotional eating is an impulsive mood-regulation strategy that often follows psychological distress. Mindfulness is associated with less impulsive behaviour. Mindful eating involves a considered awareness of hunger and satiety, and conscious, non-automatic, food choices. This study examines the moderating role of mindfulness on the relationship between distress and emotional eating. PARTICIPANTS AND PROCEDURE Participants (N = 392) completed self-report measures on distress, mindfulness and emotional eating, after which moderation analysis was carried out. RESULTS Mindfulness was negatively associated with emotional eating, but only when distress was low. The most important facets of mindfulness for this were being able to describe one’s emotional state and a non-judgemental response to that state. CONCLUSIONS These results support previous findings that mindfulness reduces the impact distress has on emotional eating. Future research could explore interventions that enable individuals to describe their emotional state in the moment to reduce preoccupation with food during times of distress.
Stable climate corridors promote gene flow in the Cape sand snake species complex (Psammophiidae)

Climate shifts during the Quaternary Period have driven changes in regional range dynamics for many species, influencing population structure of species and in some cases promoting speciation. Within southern Africa, the psammophine snakes Psammophis trinasalis and P. namibensis were historically considered subspecies of P. leightoni but were elevated to species rank based on ecological differences. Preliminary phylogenetic analyses suggested intraspecific, not interspecific genetic variation between these taxa, but this finding was based on very limited data and could not be confirmed. To assess the level of genetic differentiation within the P. leightoni species complex, we explored the evolutionary history of these snakes by combining phylogenetic analyses, species distribution modelling and an examination of morphology. We generated a comprehensive, multi‐gene phylogeny for Psammophis that included wider geographic sampling of the three species in the complex. Using this phylogeny, Bayesian and distance‐based species delimitation analyses showed intraspecific, not interspecific divergences between taxa in the complex, suggesting that they collectively represent a single taxon. Furthermore, non‐metric multidimensional scaling analysis of scalation characters showed no differences between the species. Moreover, palaeo‐modelling at three time periods since the last interglacial period suggest that there have been varying levels of connectivity between these taxa, which has likely facilitated gene flow between them. Given the evidence, we propose that the P. leightoni complex represents a single species and therefore formally synonymise the three species.
Determination of rearing practices combinations increasing the carcase weight according to the heifers slaughter age by the decision tree method

Abstract This work aims to identify the rearing practices which increase the carcase weight according to slaughter age. For this purpose, an innovative statistical method, the decision tree method, was used to identify the most influential action levers on the carcase weight, with associated thresholds values and modalities, among the rearing practices applied throughout the animals’ life. The data of 636 heifers carcases were collected from the slaughterhouse and the rearing practices from 45 farms by survey. Firstly, classifications were done to define slaughter-age classes and carcase-weight classes. Three slaughter-age classes (younger, mid-age, older) and 3 carcase-weight classes (lighter, intermediate, heavier) were defined, then these two classifications were crossed. The decision tree method highlighted that the influence on carcase weight of the life periods of the animals (i.e. suckling, growth, and finishing periods) and the related rearing practices were different according to the slaughter age of the heifers. For the younger-slaughtered animals, the most influential rearing practices on the carcase weight were the suckling duration, the concentrate supply during growing, the distributions of compound feed and grass silage in-stall during growing. For the mid-age slaughtered animals, the rearing practices identified as the most influential were the concentrate amount distributed in-stall during finishing, the meal supply in-stall during finishing and the cereals supply at pasture during growing. For the older-slaughtered animals, the compound feed supply at pasture during finishing and the concentrate amount distributed in-stall during growing were the most influential on the carcase weight. HIGHLIGHTS Decision tree: an innovative statistical method to identify action levers on carcase weight among the applied rearing practices throughout the life. The influential periods and rearing practices were distinct according to the slaughter-age of the animals.
‘I Blame House Hunters’: How real estate agents use property TV to manage clients and establish expertise

ABSTRACT Property television is an increasingly popular form of lifestyle media, but its practical impact on the housing market is mostly unknown. In this analysis, I reveal one way that property television intervenes in the housing process by describing how it is interpreted and deployed as a cultural resource by real estate agents. Drawing on diverse forms of data, I find that while real estate agents are often critical of property television, they strategically use it to establish themselves as market experts; indeed, their criticisms set up a direct comparison between ‘unrealistic’ property television depictions and their own status as reliable and valuable market guides. These findings contribute to research on property and reality television, as well as to research on the role of culture in market exchange, by revealing the tangible role of this salient cultural object within housing interactions.
Reversing the Bamboo Network: Chinese capital, geopolitics, and institutions in Southeast Asia

ABSTRACT This study applies a comparative political economy approach to institutional theory by considering institutional convergence and geopolitics as determinants of Chinese outward foreign direct investment (OFDI). Using country-level data for a sample of Asian countries, including Bamboo Network countries or countries with prominent overseas Chinese business networks in Southeast Asia, and other countries identified in the Varieties of Capitalism literature, the dynamic panel analysis from 2007 to 2019 finds that Chinese OFDI is significantly positively affected by the interaction between greater formal institutional distance from China and a similar state-backed institutional configuration. Conversely, active territorial disputes with China and formal arbitral proceedings against this country have significant and negative effects. This study finds that Chinese OFDI in general and specifically the reversal of the Bamboo Network, or the flowing back of Chinese capital into Southeast Asian economies that initially invested in China’s rise and integration into the global economy, are conditioned upon geopolitical tensions and convergence in terms of institutional configuration but not institutional distance.
Allelopathic Effect of Aqueous Extracts of Parthenium (Parthenium Hysterophorus L.) Parts on Seed Germination and Seedling Growth of Maize (Zea Mays L.)

Twice repeated experiment was carried out under laboratory conditions to investigate the allelopathic effects of aqueous extracts of Parthenium hysterophorus L. shoot (stem + branch) and leaf, at 0, 5, 10 and 15 g L -1 (w/v) concentrations on maize ( Zea mays L .) seed germination, seedling growth (shoot and root length) and biomass production. The treatments were laid out in completely randomized design with the factorial arrangement in four replications. Result indicated that the highest germination percentage (98.75%) was recorded from control whereas the lowest (43.75 %) was from stem extract at15 g L -1 concentration level. Similar trend was also observed by leaf extract. Root and shoot length of maize crop was reduced by 91.4 % and 70.8% by 85.6 and 35.8% leaf extracts and stem extracts respectively hence the roots were more sensitive to allelopathic effect than shoot. Extract of both leaf and stem at 15 g L -1 strongly reduced fresh and dry biomass of the maize seedling. The highest (100,100 %) tolerance index was recorded from control whereas, the lowest (8.62, 14.74%) was recorded from leaf and stem extract at 15 g L -1 concentration level respectively. Leaf aqueous extract showed more phytotoxic effect (91.37 %) than stem extracts (85.25) at 15 g L -1 whereas was the minimum recorded in control (0.0%). 15 g L -1 minimum value of vigor index (200, 539.2) and higher inhibition potentials (62.5 and 55.78%) were recorded from leaf and stem respectively. therefore allelopathic effect by the parthenium extracts is concentration-dependent manner. Leaf extract had shown highest inhibition potential followed by the stem.
Ruthenium p-cymene complexes with α-diimine ligands as catalytic precursors for the transfer hydrogenation of ethyl levulinate to γ-valerolactone

The ruthenium compounds [(η6-p-cymene)RuCl{κ2N-(HCNR)2}]NO3 (R = 4-C6H4Me, [1]NO3; 4-C6H4OH, [2]NO3; C6H11Cy, [3]NO3; 4-C6H10OH, [4]NO3; tBu, [5]NO3) were prepared in high yields from [(p-cymene)RuCl2]2, AgNO3 and the appropriate α-diimine. Compounds [2]PF6 and [4]PF6 were obtained by a straightforward reaction of [(η6-p-cymene)RuCl(MeCN)0.66]PF6, [6]PF6, with α-diimine, whereas [4]BPh4 was obtained by metathesis between [4]NO3 and NaBPh4. All the ruthenium products were characterized by analytical methods, IR, NMR and UV-Vis spectroscopy; in addition, the structure of [1]NO3 was ascertained by an X-ray diffraction study. Compounds [1–4]NO3, [4]PF6 and [4]BPh4 were investigated as catalytic precursors in the transfer hydrogenation reaction of ethyl levulinate to γ-valerolactone in isopropanol solution under microwave irradiation. [4]BPh4 was revealed to be the best catalytic precursor, affording γ-valerolactone in 62% yield under optimized experimental conditions.
Evaluation of shallow water waves modelled by the Rosenau-Kawahara equation using pseudo-compact finite difference approach

This paper presents a finite difference method for the Rosenau-Kawahara equation, which is performed under pseudo-compactness; this facilitates accuracy improvement. It is shown that the proposed scheme can generate a unique numerical solution with second-order convergence in both space and time and that the solution is stable with respect to . Also, it turns out that discrete mass and energy at each time step maintain; hence conservation. To guarantee these theoretical results, some numerical experiments are conducted to show how accurate and efficient the scheme can perform. Furthermore, comparisons between the presented method and some existing ones are provided in order to ensure improvement.
Adsorptive removal of methylene blue by chemically treated cellulosic waste banana (Musa sapientum) peels

ABSTRACT Acid-treated banana peel (ATBP) was developed by H2SO4 activation to be a potential adsorbent for methylene blue (MB) from aqueous solution. Batch mode adsorption studies were conducted by varying adsorbent dosage (0.02–0.30 g), solution pH (3–12), initial MB concentrations (10–300 mg/L) and contact time (0–1440 min). The adsorption data of MB by ATBP were in agreement with Langmuir isotherm, with maximum adsorption capacities of 250 mg/g at 303 K. The pseudo-first-order kinetic model best described the kinetic data. The adsorption of MB onto ATBP surface was endothermic in nature and spontaneous under the experimented conditions. Results supported the potential use of the ATBP as an effective adsorbent for the treatment of cationic dyes such as MB from aqueous solution.
