Solid-Phase Separation and Green Removal of Amprolium Hydrochloride Veterinary Drug from Aqueous Media Using Dolomiaea Costus Roots as New Biosorbent
Authors: Mohamed Amr
Published: October 2023

The roots of the Dolomiaea costus (SCO) plant were used as a new, low-cost, eco-friendly, and efficient biosorbent for the removal of Amprolium hydrochloride (AMP) antibacterial veterinary drug residues from aqueous media. The effect of different parameters, such as the initial concentration of AMP, pH, contact time, adsorbent dosage, and temperature, was investigated. The results showed that the best removal of the AMP drug by SCO was reached at a pH of 3.6 at a contact time of 80 min by a sorbent dosage of 0.04 g at a temperature of 45°C. Adsorption isotherm studies indicated that the AMP removal correlates more with the Freundlich isotherm with R2= 0.991. The maximum adsorption capacity has reached 83% based on the adsorption isotherm studies. The kinetics studies showed that adsorption follows a pseudo-second-order model with R2 = 0.999. The thermodynamic studies showed that the adsorption process of AMP on SCO is spontaneous in nature and exothermic, with an increase in randomness during the adsorption.
All That Glitters: The Golden Age of Rome in the Ars Amatoria
Authors: Paul Joshua M.
Published: October 2023

Abstract: I argue that Ovid depicts Rome as a Golden Age at the beginning of Book 1 of the Ars Amatoria, long before he makes the comparison explicit in Books 2 and 3. My approach is largely comparative, as I consider motifs common across various representations of the aurea aetas , such as commerce between gods and men and the absence of sailing. I then consider this new vision of paradise on earth in the context of the four long-recognized treatments of the Golden Age in the Ars Amatoria. Ovid’s sense of irony exposes faults in supposed Golden Ages and instead praises modernity for reasons completely counter to the moralizing of the Augustan regime.
Viewpoint-dependent highlight depiction with microdisparity for autostereoscopic displays
Authors: Huang Tianqi , Li Ruiyang , Ma Longfei , Liao Hongen
Published: October 2023

The rendering of specular highlights is a critical aspect of 3D rendering on autostereoscopic displays. However, the conventional highlight rendering techniques on autostereoscopic displays result in depth conflicts between highlights and diffuse surfaces. To address this issue, we propose a viewpoint-dependent highlight depiction method with head tracking, which incorporates microdisparity of highlights in binocular parallax and preserves the motion parallax of highlights. Our method was found to outperform physical highlight depiction and highlight depiction with microdisparity in terms of depth perception and realism, as demonstrated by experimental results. The proposed approach offers a promising alternative to traditional physical highlights on autostereoscopic displays, particularly in applications that require accurate depth perception.
Photonic skin-topological effects in microring lattices

Published: October 2023

We investigate the non-Hermitian Hofstadter–Harper model composed of microring resonators, in which the non-Hermitian skin effect (NHSE) is particularly analyzed. The effect is achieved through the interaction between well-designed gain–loss layouts and artificial gauge fields. Remarkably, we reveal the emergence of a hybrid skin-topological effect (HSTE), where only the original topological edge modes convert to skin modes while bulk modes remain extended. By changing the distributions of gauge fields, we show the NHSE can manifest itself in bulk modes and be localized at specific edges. Using the equivalence of sites in the bulk or at boundaries to 1D SSH chains, we analyze the potential cancellation of NHSE in these configurations. Additionally, we demonstrate a new, to the best of our knowledge, type of HSTE in topological insulators which emerge at any gain–loss interfaces. The study may improve the understanding of the NHSE behavior in 2D topological systems and provide a promising avenue for tuning light propagation and localization.
Optimizing wavefront coding for extended depth of field: a synchronous algorithm for optical element and decoding optimization
Authors: Li Yidan , Lyu YuXing , Wang JunHua , Hu Kai , Jiang Ying , Ye Lu , Xu Min
Published: October 2023

Wavefront coding (WFC) combines phase mask design and image restoration algorithm to extend the depth of field (DOF) for various applications. However, discrete design limits finding globally optimal solutions, increasing the complexity of system design, and affecting the accuracy and robustness of image restoration. An end-to-end imaging system design has emerged to break through these limitations by integrating optical design and image processing algorithms. In this study, we propose an algorithm that synchronously optimizes the optical elements and decoding algorithm in WFC using ray-tracing simulation. We also derive formulas for the optical layer’s forward and backward propagation for joint optimization of the optical layer and decoding algorithm. Experimental verification demonstrates the algorithm’s effectiveness in optimizing the WFC system and offers improved performance under a unified design framework.

Published: October 2023

We have successfully achieved the synthesis of heterojunction consisting of WSe2 and BN, by using a liquid phase exfoliation method，and characterization of the prepared materials under the microstructure. The WSe2/BN heterojunction was used as a saturable absorber in the Tm:YAP laser for passively Q-switched operation, and a pulsed laser with an output wavelength around 2 μm range was successfully obtained. After comparing the effects of resonators composed of different cavity mirrors, it is concluded that when the curvature radius of the input mirror is 250mm and the transmittance of the output coupler is 2.5%, the best output performance was obtained, and the output power is 834mW, with a repetition rate of 43.51 kHz and a minimum pulse duration of 1.28 µs, corresponding to a peak power of 14.97 W and a maximum single pulse energy of 19.17 µJ.

Published: October 2023

The publication of tourism statistics often does not keep up with the highly dynamic tourism demand trends, especially critical during crises. Alternative data sources such as digital traces and web searches represent an important source to potentially fill this gap, since they are generally timely, and available at detailed spatial scale. In this study we explore the potential of human mobility data from the Google Community Mobility Reports to nowcast the number of monthly nights spent at sub-national scale across 11 European countries in 2020, 2021, and the first half of 2022. Using a machine learning implementation, we found that this novel data source is able to predict the tourism demand with high accuracy, and we compare its potential in the tourism domain to web search and mobile phone data. This result paves the way for a more frequent and timely production of tourism statistics by researchers and statistical entities, and their usage to support tourism monitoring and management, although privacy and surveillance concerns still hinder an actual data innovation transition.
Extended theory of planned behavior to explain the influence mechanism of low-speed driving behavior
Authors: Xu Jinliang , Liu Huan , Liu Xianyong , Gao Chao
Published: October 2023

Low-speed driving is an underestimated dangerous behavior that may cause safety issues, such as speed dispersion and traffic flow bottlenecks. To investigate the influence mechanism of low-speed driving behavior, this study constructed the low-speed specific model (LSSM) by extending theory of planned behavior (TPB). The LSSM incorporated two factors, namely, risk perception and behavior habit, into the standard TPB components (attitude, subjective norm, perceived behavioral control, and behavior intention). Web-based questionnaires were used to collect data from a valid sample of 374, of which males accounted for 50%. The participants were aged from 18 to 65 years (M = 35.40, SD = 0.88). The structural equation model was applied to calculate and validate the interrelationships among the components of LSSM. Results showed that the LSSM could explain the variance in low-speed driving behavior and behavior intention by 46% and 76%, respectively. Meanwhile, attitude (β = 0.52, p < 0.001) and behavior habit (β = 0.48, p < 0.001) had the strongest positive influence and prediction power over low-speed driving behavior, respectively, whereas subjective norm (β = 0.05, p > 0.01) and perceived behavioral control (β = -0.12, p > 0.01) showed few significant in influencing the intention. LSSM also showed that people who were sensitive to driving risk perception would avoid low-speed driving behaviors and attitudes. Our findings may provide theoretical support for interventions on low-speed driving behavior.

Background

A number of studies have looked at neonatal structural birth defects. However, there is no study with a comprehensive review of structural anomalies. Therefor we aimed to verify the best available articles to pool possible risk factors of structural congenital anomalies in resource limited settings.

Setting

Genuine search of the research articles was done via PubMed, Scopes, Cochrane library, the Web of Science; free Google database search engines, Google Scholar, and Science Direct databases. Published and unpublished articles were searched and screened for inclusion in the final analysis and Studies without sound methodologies, and review and meta-analysis were not included in this analysis.

Participants

This review analyzed data from 95,755 women who have birthed from as reported by primary studies. Ten articles were included in this systematic review and meta-analysis. Articles which have no full information important for the analysis and case reports were excluded from the study.

Results

The overall pooled effect estimate of structural congenital anomalies was 5.50 [4.88–6.12]. In this systematic review and meta-analysis maternal illness effect estimate (EI) with odds ratio (OR) = 4.93 (95%CI 1.02–8.85), unidentified drug use OR = 2.83 (95%CI 1.19–4.46), birth weight OR = 4.20 (95%CI 2.12–6.28), chewing chat OR = 3.73 (95%CI 1.20–6.30), chemical exposure OR = 4.27 (95%CI 1.19–8.44) and taking folic acid tablet during pregnancy OR = 6.01 (95%CI 2.87–14.89) were statistically significant in this meta-regression.

Conclusions

The overall pooled effect estimate of structural congenital anomalies in a resource limited setting was high compared to better resource countries. On the Meta-regression maternal illness, unidentified drug use, birth weight, chewing chat, chemical exposure and never using folic acid were found to be statistically significant variables Preconception care and adequate intake of folic acid before and during early pregnancy should be advised.

Published: October 2023

Introduction

The COVID-19 pandemic has had an extensive impact on public health worldwide. However, in many countries burden of disease indicators for COVID-19 have not yet been calculated or used for monitoring. The present study protocol describes an approach developed in the project “The Burden of Disease due to COVID-19. Towards a harmonization of population health metrics for the surveillance of dynamic outbreaks” (BoCO-19). The process of data collection and aggregation across 14 different countries and sub-national regions in Southern and Eastern Europe and Central Asia is described, as well as the methodological approaches used.

Materials and methods

The study implemented in BoCO-19 is a secondary data analysis, using information from national surveillance systems as part of mandatory reporting on notifiable diseases. A customized data collection template is used to gather aggregated data on population size as well as COVID-19 cases and deaths. Years of life lost (YLL), as one component of the number of Disability Adjusted Life Years (DALY), are calculated as described in a recently proposed COVID-19 disease model (the ‘Burden-EU’ model) for the calculation of DALY. All-cause mortality data are collected for excess mortality sensitivity analyses. For the calculation of Years lived with disability (YLD), the Burden-EU model is adapted based on recent evidence. Because Covid-19 cases vary in terms of disease severity, the possibility and suitability of applying a uniform severity distribution of cases across all countries and sub-national regions will be explored. An approach recently developed for the Global Burden of Disease Study, that considers post-acute consequences of COVID-19, is likely to be adopted. Findings will be compared to explore the quality and usability of the existing data, to identify trends across age-groups and sexes and to formulate recommendations concerning potential improvements in data availability and quality.

Discussion

BoCO-19 serves as a collaborative platform in order to build international capacity for the calculation of burden of disease indicators, and to support national experts in the analysis and interpretation of country-specific data, including their strengths and weaknesses. Challenges include inherent differences in data collection and reporting systems between countries, as well as assumptions that have to be made during the calculation process.

The primary aim of revascularization in stable coronary artery disease (CAD) is symptom relief. The severity of symptoms is usually evaluated by the physician, not by the patient. We examined the agreement between physician- and patient-reported Canadian Cardiovascular Society (CCS) scores among patients scheduled for elective coronary angiography in a cross-sectional study. Patients (n = 650) and cardiologists evaluated the severity of angina symptoms by filling the CCS questionnaire before coronary angiography. Patients were divided into those without CAD (stenosis diameter <50%, n = 445) and those with CAD (stenosis diameter >50%, n = 205). CAD patients were further divided into three groups according to disease severity (single-, double- or triple-vessel disease). The mean age of the patients was 67.6 (9.9) years and 50.6% were women. In 51.8% (95% CI 44.5%–59.0%) of patients with CAD and 51.9% (95% CI 47.0%–56.8%) of those without, physician- and patient reported CCS scores agreed. The physician reported better CCS scores in 33.9% (95% CI 27.6%–40.7%) of patients with CAD and 36.2% (95% CI 31.8%–41.0%) of patients without CAD. The proportions of full or partial agreement between physician- and patient reported CCS scores were similar across the CAD severity groups. To summarize, we observed a significant discrepancy between the physician- and patient-reported symptom severity in patients with or without CAD scheduled for angiography. The physician underestimated the symptoms in third of the cases. Thus, patient-reported symptom severity, rather than physician’s evaluation, should be the cornerstone of treatment decisions.
Discovering SNP-disease relationships in genome-wide SNP data using an improved harmony search based on SNP locus and genetic inheritance patterns

Published: October 2023

Advances in high-throughput sequencing technologies have made it possible to access millions of measurements from thousands of people. Single nucleotide polymorphisms (SNPs), the most common type of mutation in the human genome, have been shown to play a significant role in the development of complex and multifactorial diseases. However, studying the synergistic interactions between different SNPs in explaining multifactorial diseases is challenging due to the high dimensionality of the data and methodological complexities. Existing solutions often use a multi-objective approach based on metaheuristic optimization algorithms such as harmony search. However, previous studies have shown that using a multi-objective approach is not sufficient to address complex disease models with no or low marginal effect. In this research, we introduce a locus-driven harmony search (LDHS), an improved harmony search algorithm that focuses on using SNP locus information and genetic inheritance patterns to initialize harmony memories. The proposed method integrates biological knowledge to improve harmony memory initialization by adding SNP combinations that are likely candidates for interaction and disease causation. Using a SNP grouping process, LDHS generates harmonies that include SNPs with a higher potential for interaction, resulting in greater power in detecting disease-causing SNP combinations. The performance of the proposed algorithm was evaluated on 200 synthesized datasets for disease models with and without marginal effect. The results show significant improvement in the power of the algorithm to find disease-related SNP sets while decreasing computational cost compared to state-of-the-art algorithms. The proposed algorithm also demonstrated notable performance on real breast cancer data, showing that integrating prior knowledge can significantly improve the process of detecting disease-related SNPs in both real and synthesized data.
Latent profile analysis on the effectiveness of tutor performance: Influence on medical students’ engagement in blended problem-based learning
Authors: Yun Heoncheol , Kim Seon , Han Eui-Ryoung
Published: October 2023

Tutor performance is a critical factor for the success of a problem-based learning (PBL) curriculum. This study investigated medical students’ perceptions of the effectiveness of tutor performance and the relationships with learning engagement (behavioral, emotional, and cognitive engagement) in the blended PBL approach. This study employed a cross-sectional survey and data were collected from 238 first-year and second-year medical students. Latent profile analysis (LPA) was used to investigate how individual students’ perceptions of tutor performance can be clustered. Follow-up multiple one-way analyses of covariance (ANCOVA) were performed to examine the relationships with students’ learning engagement in PBL activities. The effectiveness of tutor performance perceived by students was classified into lowly, moderately, and highly effective tutors. These clustering profiles were significantly related to the different types of learning engagement in the blended PBL process. Hence, this study highlights that the tutor is one of the key aspects of assessing the implementation of blended PBL since student performance is positively associated with the perception of tutor effectiveness.

Published: October 2023

Epoxy thermal conductive adhesives with high thermal conductivity and dynamic mechanical properties are important thermally conductive materials for fabricating highly integrated electronic devices. In this paper, micro-Al2O3 is used as a thermally conductive filler for the epoxy resin composite and investigated the effect of micron-sized alumina particle size on the thermal conductivity and dynamic mechanical property of epoxy resin by the transient planar hot plate method and DMA (Dynamic mechanical analysis). The experimental results show that with the same amount of alumina filling, the thermal conductivity and Tg (glass transition temperature) of epoxy/Al2O3 composite material decrease with the increase of alumina particle size. The maximum thermal conductivity of the composite material is 0.679 (W/mK), while the energy storage modulus of epoxy/Al2O3 composite material increases with the increase of alumina particle size, and the maximum energy storage modulus of the composite material is 160MPa. Compared with pure epoxy resin, the thermal conductivity and energy storage modulus have increased by 2.7 and 3.2 times, respectively. The epoxy/Al2O3 composite was applied to the COB (Chips On Board) type LED package, and the substrate temperature of the LED dropped to the lowest after 1.5 hours of operation using EP-A5 composite, and the temperature was stabilized at 38.2°C, indicating that the addition of 5-micron alumina composite has the best heat dissipation in the COB type LED package. These results are critical for the implementation of particulate-filled polymer composites in practical applications because relaxed material specifications and handling procedures can be incorporated in production environments to improve efficiency.

Published: October 2023

Background and Aim: Canine babesiosis, caused by the protozoan parasite Babesia canis, is characterized by clinical manifestations, including hemolytic anemia, thrombocytopenia, multiple organ failure, and may result in death. This disease is detected using conventional blood smears, which are time-consuming and have low sensitivity. This study aimed to investigate a more rapid and sensitive method for detecting B. canis infection in dogs by examining the expressed serum protein profiles using proteomics. Materials and Methods: We collected six sera samples from three healthy and three B. canis-infected dogs diagnosed using blood smear and polymerase chain reaction. We analyzed the proteins using two-dimensional gel electrophoresis. The candidate spots from the gel were subjected to protein identification using a nano-liquid chromatography system coupled to an ion-trap mass spectrometer equipped with an electrospray ionization nano-sprayer. Results: We found that 10 protein spots were overexpressed in the serum samples from infected dogs compared with healthy dogs, which corresponded to three proteins: serotransferrin, serotransferrin isoforms X1, and hemopexin. Furthermore, analysis of the protein-protein interaction network confirmed that they strongly interacted with each other. Conclusion: This study suggests that high levels of serotransferrin and hemopexin are related to B. canis infection, making these proteins potential candidates for the development of diagnostic molecules or vaccines. Keywords: Babesia canis, blood parasite, diagnosis, proteomics.
The effects of using multi-species probiotics in late-pregnant and lactating sows on milk quality and quantity, fecal microflora, and performance of their offspring

Published: October 2023

Background and Aim: The dietary probiotics in sows during gestation to lactation period have gained considerable attention with respect to their beneficial effects on sows and their piglets’ performance and health. This study aimed to evaluate the effects of using probiotics in late-pregnant and lactating sows on milk quality, quantity, fecal microflora of sows, and growth performance of their offspring until weaning.

Materials and Methods: Thirty-four sows were equally divided into two groups (control and treatment). Only those in the treatment group were fed 5 g of probiotics at 12 weeks of pregnancy, once daily for 7 weeks, until their piglets were weaned. Colostrum samples were collected at 3, 6, 12, and 24 h after farrowing and measured for immunoglobulin concentration. Percentages of fat, protein, and lactose in colostrum, colostrum production, total intake of immunoglobulin A (IgA), immunoglobulin G (IgG), fat, protein, and lactose, the change of fecal microflora of sows, and average daily gain of piglets were measured.

Results: The results showed that there were no significant differences in the concentrations of IgA, IgG, and IgM in colostrum and the percentages of fat, protein, lactose, solid-not-fat, and total solid in colostrum between the groups; however, the colostrum production at 24 h in the treatment group (6,075.29 mL) was higher than in the control group (4,809.54 mL). Higher total intakes of IgA and IgG as well as total intake of fat, protein, and lactose, particularly at 3 h after farrowing, were found in the treatment group. Probiotic supplementation remarkably altered the microbiota community at the phylum level. We found that Firmicutes and Bacteroidetes are the dominant phyla, present in the gut of more than 90% of pregnant and lactating sows. Changes in microbial proportions were observed due to the changes of pig production stage. The weaning weight of the treatment group was higher than in the control group (6.34 ± 1.71 vs. 4.84 ± 1.29 kg, respectively).

Conclusion: Feeding of multi-species probiotic BACTOSAC-P™ during late pregnancy and lactation in sows positively influenced colostrum production. In this experiment, the use of BACTOSAC-P™ improved the yield of colostrum production. The high immunoglobulin concentration and high yield of the colostrum of sows with a diet supplemented with BACTOSAC-P™ significantly reduced piglet mortality during the suckling period. Furthermore, the probiotic diet induced changes in the fecal microbial population in sows by increasing the number of microorganisms from the Firmicutes phylum, which had positive effects on sow health and their piglets, leading to better piglet growth performance.

Keywords: fecal microflora, lactation, probiotics, swine, weaning.
Clandestinity and militant culture in Latin America, 1960s to the early 1980s: epistemological and historical reflections and an agenda for research
Authors: Rayas Lucía
Published: October 2023

Clandestinity was a central aspect of the life and organisation of the militancies of the diverse cultures of the Cold War Latin America left. Yet the topic is scarcely considered central in testimonies or historical analyses of the period. In this article I approach both clandestinity as culture and the culture of clandestinity as lived experiences, ways of organising and modi operandi among militant organisations and individuals of the period. To do this, I resort to diverse types of literature, ranging from academic analyses to personal testimonies, including fictionalised accounts. I then elaborate on the possible historical, methodological and epistemological reasons why clandestinity has not been explored in the majority of the academic or testimonial corpuses presently available, stressing the possibility, as a hypothesis, that we may still be facing silence – a main tenet of clandestinity – as political doctrine. I also briefly discuss oral history as a main tool to access knowledge of clandestinity and question whether clandestinity may be an object of the historical record.

Climate change and biodiversity loss trigger policies targeting and impacting local communities worldwide. However, research and policy implementation often fail to sufficiently consider community responses and to involve them. We present the results of a collective self-assessment exercise for eight case studies of communications with regard to climate change or biodiversity loss between project teams and local communities. We develop eight indicators of good stakeholder communication, reflecting the scope of Verran’s (2002) concept of postcolonial moments as a communicative utopia. We demonstrate that applying our indicators can enhance communication and enable community responses. However, we discover a divergence between timing, complexity and (introspective) effort. Three cases qualify for postcolonial moments, but scrutinising power relations and genuine knowledge co-production remain rare. While we verify the potency of various instruments for deconstructing science, their sophistication cannot substitute trust building and epistemic/transdisciplinary awareness. Lastly, we consider that reforming inadequate funding policies helps improving the work in and with local communities.

Published: October 2023

The purpose of this study is to verify the effect of multicultural teaching efficacy between elementary school teachers’ multicultural sensitivity and multicultural teaching competency. To find out the effect of multicultural teaching efficacy, a survey was conducted for 2 weeks at an online forum for elementary school teachers. The data of 276 teachers was analyzed using JAMOVI 2.2.5 and correlation analysis and mediating effect analysis were performed. In the result of study, first, between multicultural sensitivity, multicultural teaching efficacy, and multicultural teaching competency, there is significant positive correlation. Second, multicultural teaching efficacy and sub-variables had a partial mediating effects between multicultural sensitivity and multicultural teaching competency. This study suggests that it should focus on developing a program improving multicultural sensitivity and multicultural teaching efficacy to raise future elementary school teachers’ multicultural teaching competency.

Published: October 2023

The creative sector is one of the most rapidly growing sectors of the global economy. This sector can also play an important role in providing economic benefits for developing countries. Promoting the creative economy needs a better understanding of the underlying factors that account for its spatial distribution. One of the most important factors that may influence the development of creative industries is tolerance. This paper focuses on the spatial distribution of the creative economy across cities in Indonesia and examines its relationship with tolerance. The main data sources of this paper are the unique data produced by the Central Bureau of Statistics (Badan Pusat Statistik or BPS) and the Indonesian Agency for Creative Economy (Badan Ekonomi Kreatif or BEKRAF), in addition to the City Tolerance Index provided by the SETARA Institute. The study finds that the creative economy in Indonesia does not tend to have a high spatial concentration, indicating that cities in Indonesia have an opportunity to develop the creative economy. The analysis confirms that tolerance matters for the creation of the creative economy in Indonesia. Three components of the City Tolerance Index that influence the creative economy are the Mid-Term Regional Development Plan, discriminatory regional rules and incidents of abuses against the freedom of religion or belief. The size of the population, the Human Development Index, and the status of a city as the provincial capital play a significant role in explaining the distribution of creative economies across the cities in Indonesia.
The ‘I was here’ syndrome in tourism: The case of Poland
Authors: Chylińska Dagmara , Kosmala Gerard
Published: October 2023

Tourism appropriates tourist attractions and takes possession of them, marking them both physically and symbolically. Tourists visiting attractions tend to create distinctive marks, usually characterised by some significance in terms of self-identification, on the places and monuments visited by them, and this could be regarded as a symptom of a specific ‘I was here’ syndrome; in the present study, the authors examine the prevailing practices of marking attractions in tourist spaces, as also the marks themselves. We endeavour to identify the nature of the phenomenon and the consequences for both the attractions and the subjects managing them. The survey carried out involved sev- eral chosen sites in Poland, all of which are characterised by a recognised historic status in the realm of public space as well as a clearly identified sociocultural or legal value, which by definition imposes the requirement for adhering to a certain behavioural code when within their precincts and towards them, and excludes other kinds of behaviour. These attractions are all subject to different forms of institutionalised control, which, however, fails when it comes to safeguarding them from the practices of marking undertaken typically by tourists; these occurrences have become a routine phenomenon, which is unsurprising given the fact that the rituals of the contemporary mass and mediatised tourism have made this kind of tourist behaviour common, albeit on a lower scale than previously expected.

Published: October 2023

In the present work, a study of a metamaterial complementary split ring resonator (CSRR) microwave planar sensor for dielectric liquid characterization is carried out using HFSS software. The design consists in a CSRR-loaded two ports rectangular patch microstrip-fed grounded planar structure. The investigated liquid sample is put in a capillary glass tube lying parallel to the surface of the sensor. The liquid test tube is deposited horizontally parallel to the surface of the planar sensor. The advantage of the design lies on the fact that it allows different orientations and multiple size possibilities of the test tube. This makes it possible to explore different resonant frequencies in the 2.1 GHz frequency band. Moreover, an optimization study is carried out to achieve a high sensitivity and a high-quality factor of the proposed sensor. To better understand the operation and to further verify the feasibility of the equivalent circuit, a parallel RLC resonant circuit is used to obtain the desired Z parameter responses Z

Wire arc melting is considered one of the most efficient processes in additive manufacturing in terms of material printed to material consumed ratio. 304 stainless steel is one of the prominent stainless steels with superior corrosion resistance and mechanical properties. 304 stainless steel components were deposited by wire arc additive manufacturing, depositing subsequent layers in the same and perpendicular directions. Mechanical properties, microstructure, XRD and microtexture studies were done by EBSD have been done for both the conditions and compared. Mechanical properties were found to be similar for both the conditions whereas the microstructure and microtexture showed equiaxed grains for depositing in the same direction and columnar grains for deposition in the perpendicular direction.
A wavelet-based method in aggregated functional data analysis
Authors: dos Santos Sousa Alex Rodrigo
Published: October 2023

In this paper, we consider aggregated functional data composed by a linear combination of component curves and the problem of estimating these component curves.
We propose the application of a bayesian wavelet shrinkage rule based on a mixture of a point mass function at zero and the logistic distribution as prior to wavelet coefficients to estimate mean curves of components.
This procedure has the advantage of estimating component functions with important local characteristics such as discontinuities, spikes and oscillations for example, due the features of wavelet basis expansion of functions.
Simulation studies were done to evaluate the performance of the proposed method, and its results are compared with a spline-based method.
An application on the so-called Tecator dataset is also provided.
Upregulated microRNA-429 confers endometrial stromal cell dysfunction by targeting HIF1AN and regulating the HIF1A/VEGF pathway
Authors: Zheng Rong , Liu Yulan , Lei Yan , Yue Yan
Published: October 2023

Endometriosis (EM) is a prevalent estrogen-dependent disorder that adversely affects the life quality of many reproductive-age women. Previous evidence has suggested the significant role of miR-429 in EM; however, its molecular mechanisms underlying EM pathogenesis are unclarified. Human endometrial stromal cells (HESCs) were identified using immunofluorescence staining and flow cytometry. A mouse EM model was established by endometrial auto-transplantation. RNA and protein expression of molecules was examined using real-time quantitative polymerase chain reaction and western blotting, respectively. In vitro functional experiments showed that inhibiting miR-429 restrained HESC proliferation, migration, and invasiveness. Luciferase reporter assay confirmed that miR-429 targeted hypoxia-inducible factor 1 subunit alpha inhibitor (HIF1AN) in HESCs. HIF1AN silencing offset the negative regulation of miR-429 inhibition on the HIF1A/vascular endothelial growth factor (VEGF) signaling pathway. In vivo experiments showed that depletion of miR-429 attenuated ectopic lesion development in the mouse EM model. Collectively, suppressing miR-429 hinders the invasive behaviors of HESCs and EM progression in mice by targeting HIF1AN and regulating the HIF1A/VEGF signaling pathway.

Through bibliometric analysis, we aim to comprehensively understand the research dynamics in this field, reveal key scientific research achievements and breakthrough discoveries, and provide valuable reference and guidance for future research directions. Utilizing the Web of Science, we retrieved the literature pertaining to ultrasonics-guided regional anesthesiology (1994–2022). CiteSpace and VOSviewer were used for bibliometric and knowledge mapping analysis. Our examination encompassed publication trends, authorship patterns, institutional contributions, frequently occurring keywords, keyword clustering, and emerging terminology trends. Of the 570 papers reviewed, there was a rising trend in publications each year. The main keywords in regional anesthesia were ultrasound guidance, nerve, analgesia, and pain score. Key research areas were regional anesthesia, ultrasound guidance, approach, pain score, and plane block. The U.S. led in research. Stanford University, University of Toronto, and Cork University Hospital were central institutions. Chan V was the top author with 24 articles, while Marhofer P was the most cited at 150 times. Regional anesthesia and pain medicine were the predominant journal in both publications and citations. In conclusion, research in this field consistently grew yearly, and visualization showcased trends in ultrasound-guided regional anesthesia. These visuals provided key bibliometric insights, helping researchers further explore and understand this domain.
Random bit generation based on a self-chaotic microlaser with enhanced chaotic bandwidth

Published: October 2023

Chaotic semiconductor lasers have been widely investigated for high-speed random bit generation, which is applied for the generation of cryptographic keys for classical and quantum cryptography systems. Here, we propose and demonstrate a self-chaotic microlaser with enhanced chaotic bandwidth for high-speed random bit generation. By designing tri-mode interaction in a deformed square microcavity laser, we realize a self-chaotic laser caused by two-mode internal interaction, and achieve an enhanced chaotic standard bandwidth due to the photon–photon resonance effect by introducing the third mode. Moreover, 500 Gb/s random bit generation is realized and the randomness is verified by the NIST SP 800-22 statistics test. Our demonstration promises the applications of microlasers in secure communication, chaos radar, and optical reservoir computing, and also provides a platform for the investigations of multimode nonlinear laser dynamics.
Approaching Interaction in Iron Age Sardinia: Multi-Scalar Survey Evidence from the Sinis Archaeological Project and the Progetto S’Urachi
Authors: Gosner Linda R. , Nowlin Jessica
Published: October 2023

Using west-central Sardinia as a case study, this article explores how multi-scalar survey archaeology can be used to address questions of the intensity, nature, and scale of interaction in the Iron Age central Mediterranean. This large island played an important role in Mediterranean trade networks and was frequented and settled by Phoenicians, Carthaginians, and Romans, among others over the course of the first millennium BCE. These foreign groups interacted with local Nuragic people through trade, the exchange of ideas, and genetic admixing, which led to increasing connectivity over time. Large excavations at major colonial sites and genetic studies have reinforced the perception that interactions were felt most strongly in coastal regions, while inland communities remained more isolated. Our multi-scalar survey data, drawn from site-based survey at the inland nuraghe S’Urachi and regional survey in its surrounding territory (the Sinis Archaeological Project), supply information concerning how Iron Age interactions impacted inland rural communities. These data show how interaction transformed over time, as trade increased and agriculture intensified in response to external demands. Ultimately, we suggest that survey archaeology is an important tool for illuminating multi-scalar interaction in Sardinia and elsewhere.
