Modeling Future Potential Distribution of Buff-Bellied Hummingbird (Amazilia yucatanensis) Under Climate Change: Species vs. Subspecies

Global climate change is associated with changes in precipitation patterns and an increase in extreme weather events, which might shift the geographic distribution of species. Despite the importance of this topic, information is lacking for many species, particularly tropical birds. Here, we developed species distribution models (SDMs) to evaluate future projections of the distribution of the widespread Buff-bellied Hummingbird (Amazilia yucatanensis) and for each of the recognized subspecies (A. y. yucatanensis, A. y. cerviniventris, A. y. chalconota), under climate change scenarios. Using SDMs we evaluate current and future projections of their potential distribution for four Representative Concentration Pathway (RCPs) for the years 2050 and 2070. We also calculated the subspecies climatic niche breadth to test the relationship between their area of distribution and climatic niche breadth and their niche overlap. Future climate-change models suggested a small increase in the potential distribution of the species and the subspecies A. y. yucatanensis, but the predicted potential geographic range decreased in A. y. chalconota and remained unaffected in A. y. cerviniventris. The climatic niche of A. y. cerviniventris contained part niche space of A. y. yucatanensis and part of A. y. chalconota, but the climatic niches of A. y. yucatanensis and A. y. chalconota did not overlap. Our study highlights the importance of correctly choosing the taxonomic unit to be analyzed because subspecies will respond in a different manner to future climate change; therefore, conservation actions must consider intrinsic requirements of subspecies and the environmental drivers that shape their distributions.
Technical Introduction of Wireless Mesh Network

Abstract In the process of evolution to the next generation network, wireless is an indispensable technology. Because of its Multi-Hop characteristics, the application value of Wireless Mesh Network in the next generation Internet has been proved. Because of Mesh peer-to-peer network topology, if a node fails, it will not affect the operation of the whole network, and can effectively avoid single point of failure. As a solution to provide high-speed internet services, Wireless Mesh Network can provide network access for mobile users in its coverage area, and it has evolved into an effective solution for broadband home networks, community networks, enterprise networks and other wireless access networks.
μSR-Study of a 3% CoFe2O4 Nanoparticle Concentration Ferrofluid

Magnetic fluids based on single-domain magnetic spinel ferrite nanoparticles dispersed in various liquid media are of particular practical and scientific interest. This paper presents a muon spectroscopy study of a ferrofluid based on magnetic nanoparticles of CoFe2O4 molecules dispersed in water (H2O) with a nanoparticle concentration of 3%. In this study, it was determined that the structure and magnitude of the magnetization of a ferrofluid depend on the viscosity of the liquid itself. It was shown that, at room temperature (290 K) and under an external magnetic field of 527 G, the observed additional magnetization was ~20 G. In a small fraction of the sample under study (~20%), negative magnetization (diamagnetism) was observed. At low temperatures (~30 K), the sample acted as a paramagnet in a magnetic field. For the first time, the magnetic field inside and in the immediate vicinity of a CoFe2O4 nanoparticle has been measured experimentally using the μSR method: the value was 1.96 ± 0.44 kG; thus, direct measurement of the magnetization of a nanoscale object was performed.
Exploring the construct of the new way of thinking in the digital environment

ABSTRACT The aim of this study is to provide insights concerning the effects of the ubiquitous digital environment on the way people think and the subsequent need to equip young individuals with the necessary skills. Several studies focus on defining the so-called digital skills, also providing indications that higher cognitive skills are required. However, they do not examine how young individuals could perform better to adapt to the continuously evolving digital environment. To address this gap, the study introduces and analyses the construct of digital intelligence, representing the new way of thinking and behaviour in the digital environment. For the purposes of the study, a set of tests was given to students at Greek high schools, targeting 15–16 years old students and employing original tests to assess digital intelligence. According to the findings, digital intelligence is composed of: (1) logical reasoning, algorithms, and evaluation, (2) abstraction, decomposition, and patterns and generalisation, (3) digital emotional intelligence and communication, (4) digital safety and security, and (5) digital identity, use, literacy, and rights. Assessing digital intelligence, as proposed in this study, could be used to assist vocational guidance, employee selection and evaluation, and development of revised school curricula.
Graphical representation of structural data in the field: A methodological proposal for application in deformed areas

The description of the fabric elements represented by the linear and planar structures present at different scales is a key component of fieldwork. A scheme is proposed for the systematic registration of planes and lineations, coded as S (planar surfaces), F (folds), and L (lineations), among others, that allows for the orderly storage of the measurements taken. This scheme includes information related to the kinematics, the kinematic indicators, and the certainty or reliability ascribed to the assigned movement. In the fieldwork, the graphic representation of the structural measures in modified projection nets includes concentric circles for each dip. Direct drawing of the outcrop data is undertaken, dispensing with the use of tracing or transparent paper. The stereograms resulting from the graphic representation in the modified Wulff stereographic projection net, and the modified Schmidt equal-area net, can be complemented by rose diagrams for visualization of the spatial ordering. During field campaigns in the outcrops, it is essential to visualize the spatial orientation of the data in the diagrams to determine the main structural trends, the vergence, the kinematic nature of faults and shear zones, paleo-stress tensors, and to differentiate structural domains, among others. This information supports the reconstruction of geological and tectonic history and the establishment of relationships between the different geological processes.
Comparative Analysis of Chemical and Thermal Denatured β-Lactoglobulin AB in the Presence of Casein

Chemical denaturation and thermal denaturation of β-lactoglobulin AB in the absence and presence of αS -casein were measured at pH 2.0. It has been observed that ΔGD o , (Gibbs free energy change in absence of denaturant at 25 o C) of βlgAB: αS –casein ratios 1:1, 1:1.5 and 1:2 is increased. We report that the functional dependence of ΔGD , (Gibbs free energy change) of protein in the absence and the presence of αS -casein concentration is linear. The values of Tm (midpoint of denaturation), ΔHm (enthalpy change at Tm), and ΔCp (constantpressure heat capacity change) under a given solvent condition were measured. It has been observed that each sugar stabilizes the protein in terms of Tm and ΔGD o . The temperature that corresponds to maximum protein stability, TS, is increased in the presence of these osmolytes. The same trend was also observed for TH, the temperature corresponding to zero enthalpy change of denaturation.
Perovskite–silicon tandem solar modules with optimised light harvesting

Perovskite–silicon tandem solar cells are potentially attractive, inexpensive solutions to surpass the power conversion efficiency limits of market-leading silicon solar cells. While such tandem solar cells have been demonstrated to reach high efficiencies, they require advanced light management to utilise the solar spectrum efficiently. Moreover, area upscaling with minimal optical losses is necessary to transfer the properties of lab scale devices to commercial scale products. Here, we demonstrate four-terminal perovskite–silicon tandem solar modules with efficient light management. With rigorous optical simulations of the complete tandem stack, we design light management concepts that minimise overall reflection and enhance complementary absorption of the subcells. The optical optimisation results in four-terminal tandem power conversion efficiencies of 25.3% on 0.13 cm2 and 23.9% on 4 cm2, both exceeding the stand-alone silicon solar cell power conversion efficiency of 23.0%.
Breast cancer in Western Africa: A pilot molecular analysis of BRCA genes in early- onset breast cancer patients in Burkina Faso

Background: Breast cancer (BC) is the most commonly diagnosed cancer and the second leading cause of cancer-related deaths, after cervical cancer, among women in Africa. Even if the epidemiological data are now aligned with those relating to industrialized countries, the knowledge concerning breast cancer in Africa, in particularly in Western Africa still lack clinical data, medical treatments, and the evaluation of genetic and non-genetic factors implicated in the etiology of the disease.The early onset and the aggressiveness of diagnosed breast cancers in patients of African ancestry strongly suggest that the genetic risk factor may play an important role but up to date very few studies have been done concerning the impact of germ line mutations in breast cancer in Africa, with a negative impact on prevention, awareness and patient management.We have performed by Next Generation sequencing (NGS) the analysis of all coding regions and the exon-intron junctions of BRCA1 and BRCA2 genes, the two most important genes in hereditary breast cancer, in fifty-one women from Burkina Faso with early onset of breast cancer and or without a family history.Results: We identified six different pathogenic mutations (3 in BRCA1, 3 in BRCA2), two of which have been found to be recurrent , in 8 unrelated women.In addition, we identified, in 4 other patients, two variants of uncertain clinical significance (VUS) and two variants never previously described in literature, although one of which is present in the dbSNP database.Conclusions: The present study is the first in which the entire coding sequence of BRCA genes have been analyzed by Next Generation Sequencing in Burkinabe young women with breast cancer. Our data support the importance of genetic risk factors in the etiology of breast cancer in this population and suggests the necessity to improve the genetic cancer risk assessment. Furthermore, the identification of the most frequent mutations of BRCA1 and BRCA2 in the population of Burkina Faso will allow the development of an inexpensive genetic test for the identification of subjects at high genetic cancer risk, which could be used to design personalized therapeutic protocols.
Experimental Electron Density Distribution in Two Cocrystals of Betaines with p-Hydroxybenzoic Acid

Experimental determination of electron density distribution in crystals by means of high-resolution X-ray diffraction allows, among others, for studying the details of intra- and inter-molecular interactions. In case of co-crystals, this method may help in finding the conditions of creating such species. The results of such analysis for two co-crystals containing betaines, namely trigonelline (TRG: nicotinic acid N-methylbetaine, IUPAC name: 1-methylpyridinium-3-carboxylate) and N-methylpiperidine betaine (MPB: 1-methylpiperidinium-1-yl-carboxylate) with p-hydroxybenzoic acid (HBA) are reported. TRG-HBA crystallizes as a hydrate. For both of the co-crystals, high-quality diffraction data were collected up to sinθ/λ = 1.13 A−1. Hansen-Coppens multipolar model was then applied for modelling the electron density distribution and Atoms-In-Molecules approach was used for detailed analysis of interactions in crystals. A number of intermolecular interactions was identified, ranging from strong O-H···O hydrogen bonds through C-H···O to C-H···π and π···π interactions. Correlations between the geometrical characteristics of the contacts and the features of their critical points were analyzed in detail. Atomic charges show that in zwitterionic species there are regions of opposite charges, rather than charges that are localized on certain atoms. In case of MPB-HBA, a significant charge transfer between the components of co-crystal (0.5 e) was found, as opposed to TRG-HBA, where all of the components are almost neutral.
Genetic fuzzy system for prediction of respiratory rate of chicks subject to thermal challenges

ABSTRACT The aim of this study was to estimate and compare the respiratory rate (breath min-1) of broiler chicks subjected to different heat intensities and exposure durations for the first week of life using a Fuzzy Inference System and a Genetic Fuzzy Rule Based System. The experiment was conducted in four environmentally controlled wind tunnels and using 210 chicks. The Fuzzy Inference System was structured based on two input variables: duration of thermal exposure (in days) and dry bulb temperature (°C), and the output variable was respiratory rate. The Genetic Fuzzy Rule Based System set the parameters of input and output variables of the Fuzzy Inference System model in order to increase the prediction accuracy of the respiratory rate values. The two systems (Fuzzy Inference System and Genetic Fuzzy Rule Based System) proved to be able to predict the respiratory rate of chicks. The Genetic Fuzzy Rule Based System interacted well with the Fuzzy Inference System model previously developed showing an improvement in the respiratory rate prediction accuracy. The Fuzzy Inference System had mean percentage error of 2.77, and for Fuzzy Inference System and Genetic Fuzzy Rule Based System it was 0.87, thus indicating an improvement in the accuracy of prediction of respiratory rate when using the tool of genetic algorithms.
Polypharmacy and medication use in patients with chronic kidney disease with and without kidney replacement therapy compared to matched controls

ABSTRACT Background This study aims to examine polypharmacy (PP) prevalence in patients with chronic kidney disease (CKD) Stage G4/G5 and patients with kidney replacement therapy (KRT) compared with matched controls from the general population. Furthermore, we examine risk factors for PP and describe the most commonly dispensed medications. Methods Dutch health claims data were used to identify three patient groups: CKD Stage G4/G5, dialysis and kidney transplant patients. Each patient was matched to two controls based on age, sex and socio-economic status (SES) score. We differentiated between ‘all medication use’ and ‘chronic medication use’. PP was defined at three levels: use of ≥5 medications (PP), ≥10 medications [excessive PP (EPP)] and ≥15 medications [hyper PP (HPP)]. Results The PP prevalence for all medication use was 87, 93 and 95% in CKD Stage G4/G5, dialysis and kidney transplant patients, respectively. For chronic medication use, this was 66, 70 and 75%, respectively. PP and comorbidity prevalence were higher in patients than in controls. EPP was 42 times more common in young CKD Stage G4/G5 patients (ages 20–44 years) than in controls, while this ratio was 3.8 in patients ≥75 years. Older age (64–75 and ≥75 years) was a risk factor for PP in CKD Stage G4/G5 and kidney transplant patients. Dialysis patients ≥75 years of age had a lower risk of PP compared with their younger counterparts. Additional risk factors in all patients were low SES, diabetes mellitus, vascular disease, hospitalization and an emergency room visit. The most commonly dispensed medications were proton pump inhibitors (PPIs) and statins. Conclusions CKD Stage G4/G5 patients and patients on KRT have a high medication burden, far beyond that of individuals from the general population, as a result of their kidney disease and a large burden of comorbidities. A critical approach to medication prescription in general, and of specific medications like PPIs and statins (in the dialysis population), could be a first step towards more appropriate medication use.
What Factors Affect the Entrepreneurial Intention to Start-Ups? The Role of Entrepreneurial Skills, Propensity to Take Risks, and Innovativeness in Open Business Models

Start-ups are launched every day, and most of them will fail at the same pace. Worldwide unemployment has become a major concern due to the geometric increase in the population. However, job opportunities are not created at the same pace as the overall population, and jobless people are becoming a burden on the economy. This situation led to introduce a system that helps people become self-employed and gives dignity to their lives. Prior studies reported that many factors could motivate an individual to pursue entrepreneurial projects. However, there is still a gap in identifying a path that promotes entrepreneurial intention among young graduates. Therefore, the purpose of the current study is to determine the effect of self-motivation, family support, peer influence, and institutional support on entrepreneurial intention through entrepreneurial skills, propensity to take risks, and innovativeness. Data were collected from 416 business students from six public and private sector universities in Pakistan. The results revealed that self-motivation, family support, peer influence, and institutional support positively and significantly affected entrepreneurial intention. The mediating role of entrepreneurial skills, a propensity to take risks, and innovativeness also enhances entrepreneurial intention among young graduates. A categorical analysis was conducted to explain the characteristics of the individuals motivated to launch start-ups. The results revealed a significant difference in the grouping variables of gender and education. The conceptual model provides more pronounced results in the case of male and post-graduate students. These findings may motivate young graduates to start new venture capital start-ups based on open business models. In this way, they can contribute to the complex and evolutionary economics that accelerate efficiency through technological innovation.
Recent Advances in Crop Establishment Methods in Rice-Wheat Cropping System-a Review

Traditional practices of growing rice and wheat in Asian countries involve a huge cost in establishment methods adopted by farmers which not only limit the yield and return but also degrade soil and require more water. Adaptation of improved crop establishment methods suitable under adverse climatic conditions is of utmost importance for scientific utilization of natural resources and to maintain the sustainability of rice- wheat cropping system Therefore, an attempt has been made in this chapter to review precision rice establishment methodology viz., direct seeding, non-puddle/unpuddled transplanting, bed transplanting, strip tilled and single pass shallow tilled rice, double transplanting and system of rice intensification (SRI) and wheat establishment methods viz., zero tilled, strip tilled and bed planted wheat. These are recent improved crop establishment techniques that can be used under specific agro-ecological conditions for enhancing yield and resource conservation in Indo-gangetic plains of Eastern India.
Investigating social capital, trust and commitment in family business: case of media firms

PurposeThe purpose of this paper is to investigate social capital's effect on family business development in selected family media firms.Design/methodology/approachThe statistical population includes 100 individuals who run a family business in this industry. Eighty individuals are selected as the research sample through the stratified random sampling method. The data are collected using a questionnaire. The authors used structural equation modelling method for data analysis.FindingsThe results indicate that social capital affects the development of family businesses in media firms. According to the results obtained from the structural equation test, the effect of the relational dimension of social capital on trust and the effect of the cognitive and structural dimensions of social capital on trust are supported, while the effect of the relational dimension of social capital on commitment as well as the effect of the cognitive dimension of social capital on trust are not supported.Practical implicationsThis research could help family firms in media industries improve trust and commitment by paying attention to different aspects of social capital. Besides, it shows that even the impact of relational and cognitive social capital, respectively, on commitment and trust, are not supported; these two could affect trust and commitment, respectively.Originality/valueThe paper is among the first studies that investigate family firms in media industries. Besides, the relationships between relational, cognitive and structural aspects of social capital and trust and commitment are rarely studied in the literature as two determinants of family business development.
Teaching Young Children Early Mathematics through Music and Movement

The purpose of this study was to explore the integration of music and movement elements into young children’s mathematics classrooms. Using a qualitative approach, this research was a case study. Three teachers were purposely selected as participants for this study. The teachers were interviewed to gain information about the songs and movements they chose to employ into their instruction. Additionally, their lessons were observed to attain the ways they incorporated music and movement. These sessions were video recorded to gain a rich picture of the songs and movements incorporated as well as the benefits of such practice in the teaching and learning of mathematics. The findings from the interviews (with teachers), classroom observations, and photographs exhibited that the teachers used familiar, easy and simple songs to be incorporated in their instruction. It was also evident that embedding music and movement activities into young children's mathematics lessons had a positive impact on the students' learning of early mathematics. The students focused on what the teachers were doing and repeating after them. This enhanced their mathematics learning. The implication of this study is that mathematics instruction should be employed in a fun yet meaningful way by incorporating music and movement activities as teaching and learning activities. More importantly, is that children learn mathematics with understanding.
Do Regional Trade Agreements Enhance International Tourism Flows? Evidence from a Cross-Country Analysis

This study investigates the effect of regional trade agreements (RTAs)—including preferential and free trade agreements, customs unions, and common markets—on bilateral tourism flows. We explore these effects using a panel gravity data set of 163 destination countries, 171 source countries, and 13,589 country-pairs from 1995 to 2015. This is the first large cross-country study to undertake such an integrated analysis using the gravity framework. Results show that all types of RTAs have a positive and significant effect on bilateral tourism flows. The overall indicator of RTAs that captures the combined effect of all types of RTAs on bilateral tourism flows is also positive and significant, on average, as well as when different regions are separately evaluated. These findings underscore the importance of strong economic integration in fostering international tourism flows. Policies aimed at improving a country’s economic integration with other countries can help promote international tourism flows.
