Mechanical Behaviour of Plantar Adipose Tissue: From Experimental Tests to Constitutive Analysis

Plantar adipose tissue is a connective tissue whose structural configuration changes according to the foot region (rare or forefoot) and is related to its mechanical role, providing a damping system able to adsorb foot impact and bear the body weight. Considering this, the present work aims at fully describing the plantar adipose tissue’s behaviour and developing a proper constitutive formulation. Unconfined compression tests and indentation tests have been performed on samples harvested from human donors and cadavers. Experimental results provided the initial/final elastic modulus for each specimen and assessed the non-linear and time-dependent behaviour of the tissue. The different foot regions were investigated, and the main differences were observed when comparing the elastic moduli, especially the final elastic ones. It resulted in a higher level for the medial region (89 ± 77 MPa) compared to the others (from 51 ± 29 MPa for the heel pad to 11 ± 7 for the metatarsal). Finally, results have been used to define a visco-hyperelastic constitutive model, whose hyperelastic component, which describes tissue non-linear behaviour, was described using an Ogden formulation. The identified and validated tissue constitutive parameters could serve, in the early future, for the computational model of the healthy foot.
Synthesis, antioxidant and antitumor activities of some of new cyclobutane containing triazoles derivatives

Abstract Thiosemicarbazides (2a–e) were obtained by the interaction of furan-2-carboxylic acid hydrazide (1) with five different isothiocyanate (RNCS) derivatives. By addition of KOH to the reaction medium, ethyl, allyl, phenyl and benzyl, p-tolyl substituted 1,2,4-triazoles (3a–e) were obtained. 3a–e were dissolved in dry acetone containing K2CO3 in the presence of 2-chloro-1-(3-methyl-3-mesitylcyclobutyl) ethanone (4) to give 3,4,5-trisubstituted 1,2,4-triazole sulfanyl compounds containing a cyclobutane ring (5a–e). The structures of the final compounds were confirmed by elemental analyses, FT-IR, 1H-NMR and 13C-NMR. The antioxidant and antitumor properties of the synthesized compounds were also investigated. Three of the triazole derivatives with p-tolyl, benzyl and phenyl substituents (5c–e) displayed good antioxidant and antitumor activity in comparison to the standards. Graphical Abstract
Analysis of the optimal profit strategy of network cargo based on game theory

With the popularity of social media, the Internet celebrity economy has become a new economic phenomenon, driven by huge interests, more and more people enter the industry, one of the main ways to bring goods is targeted sales by celebrities relying on their huge fan base. However, the development of the network with the goods industry is also uneven, there are unqualified products, supervision is not in place and other problems, some carriers pay attention to the interests of blind selling goods at the expense of consumer interests, this behavior is not conducive to long-term development. Therefore, this paper analyzes the optimal profit of online goods by using Nash equilibrium on the basis of considering the interests of consumers. The key to improve profits is to reduce the return rate, and to reduce the return rate lies in whether the marketing subject can control the quality of the goods. On this basis, the probability of monitoring and non-monitoring of the marketing platform is set, and the income of the marketing platform under the strategy of product control and non-control, and consumers under the strategy of purchase and non-purchase is obtained by using repeated games. The optimal profit of online delivery and how to maintain long-term interests are analyzed. Finally, it is concluded that the long-term profit can be obtained when the control cost is low, the control profit is high, the marketing platform penalty and deduction are low and the discount rate is high.
The Plastic Interplay between Lung Regeneration Phenomena and Fibrotic Evolution: Current Challenges and Novel Therapeutic Perspectives

Interstitial lung diseases (ILDs) are a heterogeneous group of pulmonary disorders characterized by variable degrees of inflammation, interstitial thickening, and fibrosis leading to distortion of the pulmonary architecture and gas exchange impairment. Among them, idiopathic pulmonary fibrosis (IPF) displays the worst prognosis. The only therapeutic options consist of the two antifibrotic drugs, pirfenidone and nintedanib, which limit fibrosis progression but do not reverse the lung damage. The shift of the pathogenetic paradigm from inflammatory disease to epithelium-derived disease has definitively established the primary role of type II alveolar cells, which lose their epithelial phenotype and acquire a mesenchymal phenotype with production of collagen and extracellular matrix (EMC) deposition. Some predisposing environmental and genetic factors (e.g., smoke, pollution, gastroesophageal reflux, variants of telomere and surfactant genes) leading to accelerated senescence set a pro-fibrogentic microenvironment and contribute to the loss of regenerative properties of type II epithelial cells in response to pathogenic noxae. This review provides a complete overview of the different pathogenetic mechanisms leading to the development of IPF. Then, we summarize the currently approved therapies and the main clinical trials ongoing. Finally, we explore the potentialities offered by agents not only interfering with the processes of fibrosis but also restoring the physiological properties of alveolar regeneration, with a particular focus on potentialities and concerns about cell therapies based on mesenchymal stem cells (MSCs), whose anti-inflammatory and immunomodulant properties have been exploited in other fibrotic diseases, such as graft versus host disease (GVHD) and COVID-19-related ARDS.
Estimation of a Simple Structure in a Multidimensional IRT Model Using Structure Regularization

We develop a method for estimating a simple matrix for a multidimensional item response theory model. Our proposed method allows each test item to correspond to a single latent trait, making the results easier to interpret. It also enables clustering of test items based on their corresponding latent traits. The basic idea of our approach is to use the prenet (product-based elastic net) penalty, as proposed in factor analysis. For optimization, we show that combining stochastic EM algorithms, proximal gradient methods, and coordinate descent methods efficiently yields solutions. Furthermore, our numerical experiments demonstrate its effectiveness, especially in cases where the number of test subjects is small, compared to methods using the existing L1 penalty.
Job Stress and Employees' Satisfaction in the Hospitality and Tourism Sector of North East India

In the modern times, the demand for hotel and tourism services is increasing rapidly. As a result, hospitality employees face enormous professional pressure at work. This work pressure causes them stress at work. Since job satisfaction is a prerequisite for providing the highest quality services, it largely depends on the level of stress in the workplace. In this study, determinants of job stress have been identified first and then an attempt has been made to study the impact of job stress on employees’ satisfaction. The study has been conducted with the help of primary data collected from the sample respondents from the study region. The study applies factor analysis and multiple regression analysis. The study confirmed that Eustress has direct positive relations with the job satisfaction of employees. Since, the study reveals that Duration of Work (DW), Job Profile (JP), and Expectation of Management (EM) have positively influenced job satisfaction. HR Policy (HRP) and Work Pressure (WP) negatively affected job satisfaction and these aspects should be taken care of by the management.
Application of Speckle Tracking Echocardiography for Evaluating Ventricular Function after Transcatheter Pulmonary Valve Replacement

Pulmonary regurgitation usually leads to right heart dilatation and eventually right heart dysfunction, which is associated with a poor prognosis. Transcatheter pulmonary valve replacement is a developing treatment for pulmonary valve dysfunction that can take the place of traditional surgery and make up for the shortcomings of a large injury. Echocardiography plays a significant role in assessing ventricular function; however, conventional echocardiographic parameters have several limitations. Speckle tracking echocardiography has been regarded as a more accurate tool for quantifying cardiac function than conventional echocardiography. Therefore, the aim of this review was to summarize the application of speckle tracking echocardiography for evaluating right and left ventricular functions in patients after transcatheter pulmonary valve replacement.
Homestay Service for Tourist Satisfaction in Rural Areas

Homestay services are less well-known than hotel services for tourism. However, homestay is an important aspect of tourism, not just as lodging but as a travel attraction. This study examines the influence of the homestay experience on tourist satisfaction and its significance within the context of the tourism industry. The homestay experience was examined using 244 survey questionnaires. This study demonstrated that homestay experience affects destination satisfaction and behavioural intention. Homestay services are a destination attraction because tourists want to experience the destination's traditional culture. To increase destination satisfaction, include local cultural activities in the accommodation service. Therefore, this study has the potential to improve our knowledge of the hospitality sector broadly.
Interdecadal Variability of the East Asian Winter Monsoon and Its Possible Links to Global Climate Change

Odor-background segregation of unknown odorants based on stimulus onset asynchrony in honey bees

Animals use olfaction to search for distant objects. Unlike vision, where objects are spaced out, olfactory information mixes when it reaches olfactory organs. Therefore, efficient olfactory search requires segregating odors that are mixed with background odors. Animals can segregate known target odors by detecting short differences in the arrival of odorants from different sources (stimulus onset asynchrony). However, it is unclear whether animals can also use stimulus onset asynchrony to segregate previously unknown odorants that have no innate or learned relevance. Using behavioral experiments in honey bees, we here show that stimulus onset asynchrony also improves odor-background segregation of unknown odorants. The stimulus onset asynchrony necessary to behaviorally segregate unknown odorants is in the range of seconds, which is two orders of magnitude larger than the previously reported stimulus asynchrony sufficient for segregating known odorants. We propose that for unknown odorants, odor-background segregation requires sensory adaptation to the background stimulus.
Modulation of Boreal Summer Intraseasonal Oscillations over the Western North Pacific by ENSO

AbstractThe authors investigate the effects of El Nino and La Nina on the intraseasonal oscillation (ISO) in the boreal summer (May–October) over the western North Pacific (WNP). It is found that during El Nino summers, the ISO is dominated by a higher-frequency oscillation with a period of around 20–40 days, whereas during La Nina summers the ISO is dominated by a lower-frequency period of around 40–70 days. The former is characterized by northwestward-propagating convection anomalies in the WNP, and the latter is characterized by northward- and eastward-propagating convective signals over the tropical Indian Ocean/Maritime Continent. The possible mechanisms through which El Nino–Southern Oscillation (ENSO)-induced background mean state changes influence the ISO behavior are examined through idealized numerical experiments. It is found that enhanced (weakened) mean moisture and easterly (westerly) vertical wind shear in the WNP during El Nino (La Nina) are the main causes of the strengthened (weakened) 2.
Throughput Optimization in High Speed Downlink Packet Access (HSDPA)

In this paper, we investigate throughput optimization in High Speed Downlink Packet Access (HSDPA). Specifically, we propose offline and online algorithms for adjusting the Channel Quality Indicator (CQI) used by the network to schedule data transmission. In the offline algorithm, a given target BLER is achieved by adjusting CQI based on ACK/NAK history. By sweeping through different target BLERs, we can find the throughput optimal BLER offline. This algorithm could be used not only to optimize throughput but also to enable fair resource allocation among mobile users in HSDPA. In the online algorithm, the CQI offset is adapted using an estimated short term throughput gradient without specifying a target BLER. An adaptive stepsize mechanism is proposed to track temporal variation of the environment. We investigate convergence behavior of both algorithms. Simulation results show that the proposed offline algorithm can achieve the given target BLER with good accuracy. Both algorithms yield up to 30% HSDPA throughput improvement over that with 10% target BLER.
Perioperative fluid and electrolyte management in surgical neonates

Neonates with surgical conditions may experience significant electrolyte abnormalities and dehydration of varying degrees. Increased awareness of perioperative hyponatremia and its associated morbidity has led to a shift in Pediatric fluid guidelines favoring the use of isotonic fluids. However, there is a lack of evidence-based guidelines for neonatal perioperative fluid administration, resulting in the extrapolation of fluid management principles from adults and children. This article reviews perioperative neonatal fluid management.
Modeling the distribution of woodpecker species in the Jura France and in Switzerland using atlas data

Wildlife-habitat relationship (WHR) models, that relate the distribution of species to characteristics of their environment, have become a tool commonly used in wildlife management and conservation. To assess the usefulness and identify some of the limitations associated with using breeding bird atlas data to generate such models, I used maps from a local atlas and extracted simple, broad-scale habitat variables using a GIS to develop logistic regression models for seven woodpecker species in the Jura, France: the Black (Dryocopus martius), Green (Picus viridis), Grey-headed (P. canus), Great Spotted (Dendrocopos major), Middle Spotted (D. medius), and Lesser Spotted (D. minor) woodpeckers, and the Wryneck (Jynx torquilla). Although the selected independent variables were in general agreement with known ecological requirements of the species, the reliability of the models was species-specific. Despite limitations inherent to working in a grid format, the models could be used to identify areas with high probability of woodpecker presence as targets for future censuses and fine-scale habitat studies. However, an independent validation performed by applying the models to two sites in Switzerland showed that model performance outside of the Jura was low. This poor predictive generality was probably the result of important differences between the variables used for model development, and those used for the validation, although additional factors may have contributed to model failure. To further explore this issue of model generality, new logistic models were developed for the green woodpecker using the atlas distribution maps from the two Swiss sites. The effect of scale on predictive accuracy was assessed by enlarging the mesh size of the breeding bird atlas maps and increasing the minimum mapping unit of the habitat map. Cross-area predictions were not successful, possibly because the variables used in the models did not reflect differences in landscape configuration between the sites. Model composition, classification results, and predictive generality were all affected by scale. This variability suggests that caution should be used when applying a model developed in one part of a species’ range to another, and that particular attention should be given to the choice of the scale of analysis.
The Influence Of The Principal's Leadership And School Culture On The Job Satisfaction Of Private High School Teachers

Based on basic education data (DAPODIK) at the high school level in Bekasi Regency in the Odd Semester of the 2022/2023 Academic Year, the number of students of 44 public high schools in Bekasi Regency reached 45,043 students. This means that as many as 77.85% of students attend public high schools. While the number of students attending private high schools is only around 12,811 students (22.15%). As a result, as many as 60 private high schools were declared unhealthy/unhealthy, due to a shortage of students. If this continues, it is likely that in the following year, many private high schools in Bekasi Regency will close because they do not get students. Of course, this must be overcome with a strategy to improve the quality of schools, one of which is to improve the performance of private high school teachers through job satisfaction. The purpose of this study was to determine the influence of the principal's leadership and school culture on the job satisfaction of private high school teachers in Bakasi District. This study used a quantitative approach with an explanatory method with a population of all private high school teachers in Bekasi Regency totaling 848 people. Data was collected using questionnaires and analyzed using path analysis. The results of the pathway analysis showed that there was a positive influence of the principal's leadership on teacher job satisfaction. The percentage of influence contribution is 37.5%. This means that the magnitude of the influence of the principal leadership variable (X1) on teacher job satisfaction (Y) is 37.5%. The results of the pathway analysis show that there is a positive influence of school culture on teacher job satisfaction. The percentage of influence contribution is 43.7%. This means that the magnitude of the influence of school culture variables (X2) on teacher job satisfaction (Y) is 43.7%.
Structural bases of protein kinase CK2 inhibition

Protein kinase CK2 is involved in many fundamental aspects of normal cell life, but it is also able to establish favourable conditions for tumori- genesis. CK2 is elevated in various cancers, it is a potent suppressor of apoptosis, it strongly promotes cell survival, it strengthens the multi-drug resistant phenotype and can be considered a valuable drug target for cancer therapy. In this review, the structural bases of CK2 inhibition deduced from the analysis of crystal structures of CK2a-inhibitor complexes are presented and discussed. The best ATP-competitive inhibitors show an adequate hydrophobic character, an excellent shape complementarity with the unique active site of CK2, and the ability to establish polar interactions with both the hinge region and the positive electrostatic area near the conserved water W1 and the Lys68-Glu81 salt bridge. The state of the art of non-ATP-competitive inhibitors is also present- ed. (Part of a Multi-author Review)
The effect of replacing wheat flour with sesame and flax flour on the chemical composition, fatty acids, and antioxidant properties of biscuits

The purpose of this investigation was to learn more about the chemical make-up of various grains and to analyze the chemical compositions, fatty acids, and antioxidant content of biscuits made with varying amounts of sesame and flax flour (0, 10, 20, and 25% replacement ratios). The chemical composition of the biscuits created by substituting sesame flour and flax indicated that the moisture content in all samples was between 5.90 and 6.33%, although the findings showed a disparity in the percentage of moisture for the various biscuit kinds. The proportion of ash increased dramatically with the replacement rates, from 1.33 to 1.70%. The BS25% treatment had the greatest protein concentration, at 14.43%. As the rate of replacement increased, a corresponding rise in protein content was seen. There was also a correlation between the replacement rates for the treatments investigated and the proportion of fats, with the highest percentage of fats being 10.33%. The BS20% treatment had the greatest fiber percentage (12.20%). The highest carbohydrate percentages (55.10-68.33%) suggested a decreasing carbohydrate ratio when replacement rates were increased. The outcomes also demonstrated that both essential and non-essential fatty acids were present in all types of grains studied. Finally, the highest proportion of antioxidants, which reached 58%, was recorded with the biscuits without any substitutes.
