Chemical, diversity and biotechnological potential of endophytic fungi isolated from Brazilian Cerrado plants

This is a systematic review of scientific articles reporting the biodiversity of endophytic fungi isolated from endemic Cerrado plants in Brazil and exposes the potential applications of these microorganisms in the production of known and new metabolites. The “Portal de Periódicos” (CAPES), Science Direct, PubMed, Scielo, and Biblioteca Virtual em Saúde (BVS) databases were used. A total of 418 articles were found using the following sets of keywords: Endophytic, fungi, and Cerrado; endophytic, fungi, rupestrian, and grass lands; endophytic, fungi, Brazilian, and savanna; among these, 14 articles were selected. The articles were grouped into studies on the biodiversity of Cerrado endophytic fungi, chemical studies, and other subjects. All the articles were found to be related to the diversity present in the Cerrado of the southeastern and midwestern regions, they show high fungal biodiversity with Diaporthe genus predominant in almost all plants studied. In all the studies on the chemical diversity of endophytic fungi, new compounds or new natural products were found associated with a range of bioactivity, especially antifungal. It shows the great potential of endophytes in the production of new and bioactive secondary metabolites, as well as the unexplored chemical diversity of endophytes isolated from endemic plant species. The review shows that rare studies performed in regions where the Cerrado biome are predominant, including the central, north, and northeast regions, representing an important niche that is still unexplored.
An Examination of Revisit Intention Based on Perceived Smart Tourism Technology Experience

With the development of sustainable technology and the continuous innovation of people’s travel styles, smart tourism technology (STT) is widely used in various tourism fields. STT has changed the traditional travel experience while enhancing destination competitiveness. This study examines the relationships between perceived STT experience, travel experience, and revisit intention. A total of 312 valid questionnaires were collected from tourists who had the experience of using local STT in Macau. A structural equation modeling (SEM) was used to test the proposed model, and the results showed that perceived STT experience had a significant influence on the travel experience, and travel experience had a significant influence on revisit intention. The results of the research have provided valuable information for managers who are concerned about the development of STT. In addition, when designing and developing STT websites or programs, it provides effective references and suggestions for merchants or related developers of tourism destinations to formulate scientific strategies to deal with market competition, thereby enhancing the destination’s own competitiveness.

Antimicrobial Photodynamic Therapy of the Respiratory Tract: From the Proof of Principles to Clinical Application

Antimicrobial resistance (AMR) and its relevant health consequences have been explicitly framed as a shared global problem and are estimated to be one of the largest causes of death worldwide by 2050. Antimicrobial photodynamic therapy (aPDT) proposes an alternative treatment for localized infections in response to AMR’s ever-growing problem. This technique combines molecular oxygen, a non-toxic photoactivatable photosensitizer (PS), and light of appropriate wavelength, leading to the formation of cytotoxic reactive oxygen species. Besides the ability to inactivate resistant pathogens via a non-selective approach (multiple targets), a relevant advantage of aPDT resides in the fact that no evidence of microorganism resistance has ever been reported to it. In this chapter, we address some efforts to use this technology to kill bacteria in the respiratory tract, from in vitro to clinical applications. We put forward three focuses: pharyngotonsillitis, pneumonia, and preventing secondary infections during the use of a photosensitizer-functionalized endotracheal tube. The results here presented offer a foundation for what may become a much larger clinical approach to treat respiratory tract infections.
How Long Can a Wood Flooring System Last?

Wood is a natural, sustainable, and renewable material, which has been used as flooring for centuries, but not enough is known about its durability and performance over time when subjected to different degradation agents. This study proposes a methodology for the service life prediction of wood flooring systems, considering the impact of different factors that influence the floors’ durability. For that purpose, a fieldwork survey is performed to evaluate the degradation phenomena of 96 indoor wood floorings in-use conditions, located in Portugal. The data collected are converted into degradation patterns that graphically illustrate the loss of performance of wood floorings over time. An estimated service life of 44 years is obtained. This study thus allows quantifying the impact of various characteristics on the indoor wood floorings’ service life. The results reveal the high importance of the type of protection, the type of wood, and the type of floor (with a range of estimated service life values of around 18, 17 and 16 years, respectively). This study is a first step to understanding the degradation mechanisms of the wood flooring systems, in order to extend their service life, while allowing optimising of maintenance actions, thus promoting the durability and sustainability of these floorings.
Glutamine, Glutamate, and Aspartate Improves Morphology and Energy Production of Small Intestine in Piglets with Different Energy Levels Diets

Background: Weaning-stress may cause reduced energy intake for maintenance of mucosal structure. Glutamine (Gln), glutamate (Glu), and aspartate (Asp) are major energy sources for small intestine. This study investigated whether Gln, Glu, and Asp improve the intestinal morphology via regulating the energy metabolism in weaning-piglet. A total of 198 weaned-piglets were assigned to the following treatments: Control (Basal diet + 1.59% L-Alanine); T1 (Basal diet + 1% L-Gln + 0.5% L-Glu + 0.1% L-Asp); T2 (Low energy diet + 1% L-Gln + 0.5% L-Glu + 0.1% L-Asp). Jejunum and ileum were obtained on d-5 or d-21 post-weaning. Results: Improved growth performance on d-21 post-weaning were observed in T1 treatment. Both T1 and T2 treatments improved small intestinal morphology by increasing villus height, goblet cell number and decreasing crypt depth on d 5 or d-21 post-weaning. Gln, Glu, and Asp could restore the small intestinal energy homeostasis via replenishing the Krebs’ cycle and down-regulate the AMPK pathway. However, when piglets fed by a low energy diet, Gln, Glu, and Asp are not sufficient to maintain the intestinal energy balance on d-5 post-weaning so that the AMPK, beta-oxidation, and mitochondrial biogenesis are activated to meet the high energy demand of enterocytes. Conclusion: These data indicated that Gln, Glu, and Asp could restore the energy homeostasis of intestinal mucosa of piglets. And the mucosal energy metabolism showed different responses to the intervention of Gln, Glu, and Asp in piglets with a low energy diet between d5 and d21 post-weaning. These findings provide new information on the nutritional intervention for the insufficient energy intake in weaning-piglet.
Do Autonomous Vehicles Dream of Virtual Sheep? The Displacement of Reality in the Hyperreal Visions of Autonomous Vehicles

Autonomous vehicles (AVs) have received a great deal of attention in recent years, with many commentators asking how these vehicles will “see” to navigate themselves and, more important, avoid colliding with people, other vehicles, and objects. This article analyzes how AVs see and the data sets they create through Jean Baudrillard’s framework of simulation and simulacra, paying attention to how these technologies purify and classify the real into a series of representations. In doing so, it extends the existing critique of data-generating “smart” technologies and automation and additionally draws on visual theory to understand how the hyperreality of AVs is constructed. Technologies employed on AV trials such as light detection and ranging videos and virtual reality produce data sets that create a version of the urban environment that then become the model for decisions regarding the operations and management of the city. Yet, as Baudrillard theorized, such models risk being mistaken for the reality that they represent and the data set itself confusing the nature–culture divide and created hybrid geographies of the city. As a simulacrum that operates on its own underlying logic, the article argues that this version of seeing or visioning the world risks rendering it as an object of scrutiny for state and nonstate actors that override the realities and people of the city. Indeed, techno-visions and testing of AVs can lead to situations in which reality itself is manipulated to conforming with the simulation, further complicating the simulacra of the urban environments in which AV testing takes place.
Mechanisms of frictional energy dissipation at graphene grain boundaries

In light of the race towards macroscale superlubricity of graphitic contacts, the effect of grain boundaries on their frictional properties becomes of central importance. Here, we elucidate the unique frictional mechanisms characterizing topological defects along typical graphene grain boundaries that can vary from being nearly flat to highly corrugated, depending on the boundary misfit angle. We find that frictional energy dissipation over grain boundaries can originate from variations of compressibility along the surface, heat produced during defect (un)buckling events, and elastic energy storage in irreversible buckling processes. These may lead to atypical nonmonotonic dependence of the average friction on the normal load. The knowledge gained in the present study is an important step towards the understanding of frictional effects of extended grain boundaries.
Oldest Indo-Pacific Lionfish (Pterois volitans/P. miles) Recorded From the Northwestern Gulf of Mexico

Indo-Pacific lionfish (Pterois volitans/miles) were first detected off the coast of Florida in the 1980s, with aquaria release being the most likely mechanism for introduction. Since then, lionfish have proliferated through the Western Atlantic Ocean, Caribbean Sea, and Gulf of Mexico (GOM). Here, we report the oldest lionfish aged on record in the Western Atlantic, removed from Flower Garden Banks National Marine Sanctuary (FGBNMS) in the GOM. In August 2018, a research expedition removed 745 lionfish from FGBNMS, of which a subset were retained for age and growth estimation. The oldest lionfish was a 10 y old male, with total length 375 mm and weight 805 g. The back-calculated birth date (2008) preceded the first observation of lionfish at FGBNMS by 3 years (2011). It is not well understood if lionfish are having negative impacts at FGBNMS, but this report signifies the importance of continued monitoring and removal efforts of this protected area.
Weak Measurable Optimal Controls for the Problems of Bolza

Two sufficiency theorems for parametric and a nonparametric problems of Bolza in optimal control are derived. The dynamics of the problems are nonlinear, the initial and final states are free, and the main results can be applied when nonlinear mixed time-state-control inequality and equality constraints are presented. The deviation between admissible costs and optimal costs around the optimal control is estimated by functionals playing the role of the square of some norms.
USE OF ICTS TO MEDIATE THE ADMINISTRATION OF KNOWLEDGE FOR DECISION-MAKING IN DEVELOPMENT PROJECTS

Currently, an organization's knowledge emanating from an organization is reflected in its human capital, information technology, and business processes. Knowledge has become a potential resource in the economic and social environment. Therefore, knowledge management has a high impact on the decision-making of institutions. The Technological University of the Mixteca (UTM for its Spanish initials), through the Coordination for the Promotion of Development, maintains a close link between the University and the different social and economic sectors of the Mixteca Region. First making contact with rural communities and poor urban neighborhoods through the Development Promotion Brigade. As part of the functions and activities carried out by the Brigade, technical assistance and training is provided in the different productive activities in the region. These actions generate factual knowledge that including a wealth of experiences that can contribute to any instance future decisions, plans, organization, or control over the various resources necessary to carry out development projects that satisfy the needs of the communities. In this study, a strategy mediated by the use of Information and Communication Technologies (ICT) is proposed that promotes the management of organizational knowledge and the knowledge acquired in the field for the benefit of regional production and development projects. In addition, this joint work between the UTM and the Coordination for the Promotion of Development permits the creation of studies and investigation that promote community development, especially among those communities considered to be highly marginalized.
Simultaneous Arrival to Origin Convergence: Sliding-Mode Control Through the Norm-Normalized Sign Function

In this article, simultaneous arrival to origin (SATO) convergence is defined—all state elements arriving at the origin at the same time. Accordingly, a relevant sufficient condition is proposed for SATO convergence. Based on this formulation of SATO convergence, the classical and norm-normalized (NN) sign functions are revisited. Their differences are studied with applications in sliding-mode control design. Both functions (expectedly when properly invoked) contribute to system stability, while the NN sign function enables the system to accomplish SATO convergence. This finding shows the distinctive merit of the NN sign function in achieving more than finite-time stability for a sliding-mode control system. Extensions to the scenario with a networked system are studied, where, using the NN sign function, the networked system (now with the SATO convergence property) drives all the agents to reach consensus simultaneously. Additionally, for double integrator systems and Euler–Lagrange systems, singularity-free sliding-mode control laws are designed and demonstrated to achieve SATO convergence.
A multi-scale model of real contact area for linear guideway based on the fractal theory

High precision, efficiency and reliability are the unremitting pursuits of machinery manufacturing industry. As one of the pivotal function parts of high-end NC machine tool, precise linear guideway determines the machining precision and operation performance. Accurate evaluation and prediction of surface topography are the crucial effects on the matching performance of linear guideway. In this paper, the real contact area is regarded as a key parameter, a multi-scale method with the fractal theory is proposed. First, the contact area of a single asperity was obtained with Hertz contact theory. Afterwards, the contact area between rough surfaces was deduced by the fractal theory. Finally, using the proposed multi-scale contact mechanics model, the real contact area between rough plane and cylinder was obtained by integral solution. Compared with the former fractal model and GW model, the proposed model on the real contact area calculation of linear guideway is more accurate and comprehensive. The effect factors of load, fractal parameter and friction were discussed, the increasing rate of real contact area of smoother surface is greater as load increases. The proposed model may provide practical guidance for assembly accuracy and surface quality requirements at design stage.
Modeling of the dynamic hysteresis in DEAP actuator using an empirical mode decomposition based long-short term memory network

As a smart material-based actuator, the dielectric electro-active polymer (DEAP) actuator is widely considered to be a potential driving mechanism for many applications, especially in intelligent bio-inspired robotics. However, the DEAP actuator demonstrates rate-dependent and asymmetrical hysteresis phenomenon which leads to great tracking inaccuracy and even oscillatory response, severely limiting its further development. Feedforward Neural Network (FNN) model has already become a widely used method to describe this kind of strong hysteresis nonlinearity in recent years. However, the FNN has no ability to remember the historical state of long period of time which is also a very important factor to restrict hysteresis phenomenon. In this paper, a novel hybrid model, Long-Short Term Memory (LSTM) network combined with Empirical Mode Decomposition (EMD), is proposed to model the dynamic hysteresis nonlinearity in DEAP actuator. At first, the original control signal sequence is preprocessed into a series of sub-sequence by the EMD method and is reshaped by one-sided dead-zone operator. Then the input space of LSTM is conducted using the original control signal, the sub-sequence, and reshaped signal. Finally, the input space and the displacement signal are applied to train the long-short term memory network. In order to verify the performance of the proposed model, the traditional artificial back propagation neural network (BPNN) model, rate-dependent Prandtl-Ishlinskii (RPI) model, and nonlinear electromechanical (NEM) model are compared from prediction accuracy. The results demonstrate that: (1) the proposed model has a higher prediction accuracy than the traditional artificial BPNN, RPI, and NEM model; and (2) the prediction accuracy of LSTM network is significantly improved by using EMD. Therefore, the long-short term memory network combined with empirical mode decomposition is a competitive method compared to the existing state-of-the-art approach.
TOMATO FRUIT QUALITY RETENTION DURING STORAGE BY 1-MCP TREATMENT AS AFFECTED BY CULTIVAR AND RIPENING STAGE AT HARVEST

Four tomato cultivars ('Daniela', 'Patrona', 'Cherry' and 'Raf') at two ripening stages (pink and red, for the 3 first cultivars, and breaker and light pink for 'Raf') were treated with two 1-MCP doses (0.3 and 0.5 μL L -1 ). Fruit were stored at 10°C and 90% RH for 4 weeks. Samples were taken weekly, half to study fruit quality parameters during cold storage and half left at 20°C for 1 week (shelf- life). Weight loss, colour, ethylene production, °Brix/titratable acidity ratio, firmness and decay were analysed. For all cultivars and ripening stages, the treatments were effective in reducing weight loss and rate of softening, and retarding colour changes and °Brix/titratable acidity ratio changes, either during cold storage or shelf-life. A positive relationship could be established between 1-MCP dose and the different analysed parameters, the 0.5 μL L -1 dose being the most effective during cold storage and further shelf-life. For most cultivars and ripening stages, no reduction of ethylene production was detected, as a consequence of 1-MCP treatments. This might be because in tomato fruit, the ethylene climacteric peak occurred at the breaker stage, and thus at harvest all cultivars were climacteric, and only decreases in ethylene production were observed during cold storage and shelf-life. However, blocking of the ethylene receptors by 1-MCP treatment inhibited changes in fruit quality properties which are likely to be ethylene-dependent. Also, a reduction in decay was observed for those tomato fruit treated with 1-MCP, especially with the 0.5 μL L -1 1-MCP dose and harvested at the late ripening stage; almost no decay was observed during cold storage and between 2-4 fold lower recorded during shelf-life.
Existence and uniqueness of analytical solution of time‐fractional Black‐Scholes type equation involving hyper‐Bessel operator

In this paper, we consider direct problem and inverse source problem of time‐fractional Black‐Scholes type model involving hyper‐Bessel operator. Analytical solutions to these problems are constructed based on appropriate eigenfunction expansion and Erdélyi‐Kober fractional integrals whose kernel has double singularities; then, existence and uniqueness are established. At last, the results are demonstrated by explicit solutions of some examples using appropriate choice of the given data.
ENSO Diversity in a Tropical Stochastic Skeleton Model for the MJO, El Niño, and Dynamic Walker Circulation

El Niño–Southern Oscillation (ENSO) diversity has a significant impact on global climate and seasonal prediction. However, it is still a challenging problem for present-day global climate models to simulate different types of ENSO events with realistic features simultaneously. In this paper, a tropical stochastic skeleton model for the interactions among wind bursts and the Madden–Julian oscillation (MJO), the El Niño, and the Walker circulation is developed to reproduce both dynamical and statistical features of the ENSO diversity. In this model, the intraseasonal component with state-dependent noise captures general features of wind bursts and the MJO, both of which play important roles in triggering the El Niño. The thermocline feedback is the dominant mechanism for generating the eastern Pacific (EP) El Niño, while a nonlinear zonal advection is incorporated into the model that contributes to the central Pacific (CP) El Niño. Besides, a simple but effective stochastic process describing the multidecadal variation of the background Walker circulation modulates the spatial patterns and occurrence frequency of the EP and CP El Niño. This model succeeds in simulating the quasi-regular moderate EP El Niño, the super El Niño, and the CP El Niño as well as the La Niña simultaneously. It also captures the observed non-Gaussian characteristics of sea surface temperature anomalies in different Niño regions. Individual case studies highlight the outstanding skill of the model in reproducing the observed El Niño episodes and their underlying mechanisms.
