Authors: Maldonado Yessenia E. , Malagón Omar , Cumbicus Nixon , Gilardoni Gianluca 
Published: October 2023

AbstractIn the present study, the essential oil from dry leaves of Steiractinia sodiroi (Hieron.) S.F. Blake is described for the first time. The plant material, collected in the Province of Loja (Ecuador), was analytically steam-distilled in a Marcusson-type apparatus, affording an essential oil with a 0.2 ± 0.12% yield. The volatile fraction was submitted to GC–MS and GC–FID analyses, on two stationary phases of different polarity. A total of sixty-seven compounds, corresponding to 95.6–91.2% by weight of the whole oil mass, on the two columns respectively, were detected and quantified with at least one column. The quantification was carried out calculating the relative response factors of each constituent according to their combustion enthalpy. The major components were limonene (25.6–24.9%), sabinene (11.7–12.4%), germacrene D (7.7–7.0%), α-pinene (7.8–6.9%), δ-cadinene (7.3–7.0%), (E)-β-caryophyllene (4.8–4.5%), and bicyclogermacrene (3.6–3.0%). The chemical composition was complemented with the enantioselective analysis of some major chiral compounds, conducted by means of two β-cyclodextrin-based capillary columns. Three constituents, (S)-(+)-α-phellandrene, (R)-(−)-1-octen-3-ol, and (S)-(−)-limonene were enantiomerically pure, whereas (1R,5R)-(+)-β-pinene, (1S,5S)-(−)-sabinene, (R)-(−)-terpinen-4-ol, (R)-(+)-α-terpineol, and (R)-(+)-germacrene D presented an enantiomeric excess. Finally, α-pinene was present as a racemic mixture.

AbstractPotassium is essential for plant growth. However, our understanding of potassium in plant materials is limited due to a lack of systematic studies. Here, we measured potassium content in 2,040 ecosystem communities during the period 2019-2021 applying grid-sampling and explored the spatial patterns and drivers of potassium density in the Tibetan Plateau vegetation. Potassium content, density, and storage were estimated at 8.63 milligrams per grams, 21.71 grams per square meter, and 19.92 teragrams, respectively. Potassium allocation was isometric in most ecosystems, except for deserts which followed optimal partitioning. Precipitation was the main driver of potassium variations, with higher potassium in humid regions. The spatial distribution, as revealed by random forests model, indicated higher potassium in the southeastern regions but lower potassium values in the northwestern regions. Our research sheds light on climate change’s impact on vegetation potassium, offering valuable data for biogeochemical cycle optimization.

A new hierarchical algorithm based on CapsGAN for imbalanced image classification
Authors: Jabbari Hamed , Bigdeli Nooshin 
Published: October 2023

AbstractImbalanced image datasets consist of image datasets where there is a significant disparity in the number of samples across different classes. With imbalanced image datasets, learning algorithms often tend to be biased toward the majority class samples. This leads to poor classification of minority class samples as their training is not properly conducted. It becomes more complicated when the number of samples in the minority class is very low. In this paper, a novel hierarchical algorithm is proposed for generating new data using Capsule Generative Adversarial Networks (CapsGAN) to address the class imbalance problem in imbalanced image datasets. Unlike common GAN models, the proposed method incorporates an auxiliary CapsNet to identify high‐value images in both minority and majority classes. This identification is based on the ability to detect complex relationships between low‐level and high‐level features present in capsule networks. Furthermore, the proposed CapsGAN model is conditioned to generate minority class samples based on feature vectors of last capsule layer to achieve a more balanced image dataset. For evaluating the performance of the proposed model, an image dataset called CICS was collected and introduced. Extensive experiments were also conducted using various online image datasets from different domains, with varying numbers of classes and data sizes. The experimental results demonstrated that the proposed model can generate high‐quality samples in cases where the image dataset or the number of minority class samples is relatively small. Furthermore, the proposed model has maintained an accuracy of over 80% in an imbalanced ratio of 1:60.
Rezidivierende Vaginitis und Zystitis aufgrund einer Vagina und
Zervix duplex bei einer Hündin – ein Fallbericht
Authors: Conze Theresa 
Published: October 2023

ZusammenfassungDurch die unvollständige Verschmelzung der Müllerschen
Gänge können vaginale Septen bis hin zu vollständig
getrennten Vaginalkanälen entstehen. Auch zervikale Missbildungen
können hierdurch auftreten. Meist handelt es sich nur um
rudimentäre vaginale Septierungen. Über vollständig
getrennte Vaginalkanäle (Vagina duplex) sowie über die Zervix
duplex sind in der Literatur beim Hund nur vereinzelte Berichte zu finden. In
diesem Artikel wird vom Fall einer Hündin berichtet, welche aufgrund von
rezidivierender Vaginitis und Zystitis vorgestellt wurde. Die Symptome traten
jedes Mal nach der Läufigkeit auf. Die Hündin war bereits von
der Haustierärztin und einer anderen Klinik vorbehandelt worden. Bei der
Vorstellung in der Klinik wurde in der digitalen vaginalen Untersuchung der
Verdacht eines vaginalen Septums gestellt. In der sonografischen Untersuchung
und der Harnuntersuchung wurde eine Zystitis diagnostiziert, welche antibiotisch
nach Resistenztest behandelt wurde. Die Hündin wurde erneut vorstellig
zur Endoskopie der Vagina in Narkose, der Durchtrennung des vaginalen Septums
und zur Ovariohysterektomie. Hierbei wurden eine Vagina duplex und eine Zervix
duplex diagnostiziert. Auf die geplante Resektion des Septums wurde aufgrund des
großen Ausmaßes der Missbildung in Absprache mit den Besitzern
verzichtet. In der Urinuntersuchung waren keine Keime mehr nachweisbar. Nach der
Kastration zeigte die Hündin keine erneuten Symptome einer Zystitis oder
Vaginitis.

Clinical Approach to Inconclusive Subscapularis Tear Diagnosis: a
Meta-analysis
Authors: Wang Hao , Cao Xiangyu , Li Baoqiang , Ning Taiguo , Cao Yongping 
Published: October 2023

AbstractTo identify factors associated with subscapularis (SSC) tears and provide a
theoretical basis for clinical diagnosis, we included studies related to
subscapularis tears published before February 1, 2023. We screened for six
predictors across previous studies for the meta-analysis. The predictors
included age, sex, coracoid overlap (CO), coracohumeral distance (CHD),
impairment of the long head of the biceps tendon (LHB), and dominant arm. The
Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of the studies.
The risk ratios (RRs) and the weighted mean differences (WMDs) were used to
evaluate the effect size of categorical variables and continuous variables,
respectively. The Egger test was used to assess the publication bias of the
studies. Ten studies were included from seven countries. A total of 2 126
patients were enrolled, of whom 1 041 had subscapularis tears and 1 085 did not.
The study showed that age (WMD, 4.23 [95% CI, 2.32–6.15];
P<.00001), coracoid overlap (WMD, 1.98 [95% CI,
1.55–2.41]; P<.00001), coracohumeral distance(WMD, –1.03
[95% CI, –1.17– –0.88]; P<.00001), and
an injury of the long head of the biceps tendon (RR, 4.98 [95% CI,
3.75–6.61]; P<.00001) were risk factors for subscapularis tears.
These risk factors can help clinicians identify subscapularis tears early and
select appropriate interventions. The level of evidence is 3.

Uncovering Covid-19, distance learning, and educational inequality in rural areas of Pakistan and China: a situational analysis method
Authors: Zamir Samina , Wang Zhencun 
Published: October 2023

AbstractChallenges to education in rural areas have been reported for a long time, and the respective governments are continuously making efforts to address them. However, the eruption of the Covid-19 pandemic resulted in the total closure of schools and a surge in internet and distance learning. Hence, there is a need to assess the situation periodically to gauge the effectiveness of government efforts in tackling these challenges and understand the impact of the virus outbreak on the education landscape. This study focuses on rural areas of Pakistan and China, utilizing the Situational Analysis Method (SAM). The study findings revealed several key points. Firstly, in both rural Pakistan and China, Covid-19 led to an increase in the number and scope of distance learning activities. However, there is a need for better experiences to effectively manage distance learning for students, parents, and teachers. Moreover, specific issues peculiar to rural China include shortages of relevant facilities such as computers, smartphones, and poor connectivity. In contrast, rural Pakistan faces challenges of unpreparedness and higher teacher workloads. Secondly, since internet connectivity is an essential component for distance learning, rural Pakistan shows higher internet penetration compared to rural areas in China. Nevertheless, internet connection speed in China remains higher and consistent, whether in urban or rural regions. However, both countries struggle with poor internet connection in rural areas due to the lack of enough potential customers. Thirdly, rural education in both countries is plagued by poverty, inadequate funding, and many students having to endure long and hazardous journeys to school. Specific issues in rural China include poor parental care due to migration and a shortage of teachers, while rural Pakistan grapples with limited educational opportunities for children and women, insufficient educational training for teachers, issues of social norms, and attacks on schools by extremist groups.

Authors: Razia Sultana , Abu Bakar Ah Siti Hajar 
Published: October 2023

AbstractThe expansion and development of urban areas require a strategic priority of social sustainability to protect their inhabitants’ quality of life and well-being. However, social sustainability in urban areas, particularly in developing regions, becomes more apparent due to the social problems caused by rapid urbanization. The main objective of this study is to propose a model of social sustainability for socially sustainable cities in developing regions. To accomplish this objective, a quantitative research strategy was used to gather responses from residents of Dhaka city via a structured questionnaire survey; Dhaka served as a representative city from a developing region. This study used a multistage sampling technique to select 564 residents of Dhaka city. The results showed that social sustainability significantly influenced socially sustainable urban development in Dhaka, determining 38 indicators under 11 social sustainability themes using exploratory and confirmatory factor analysis utilizing structural equation modeling. The implication of this model serves as a guiding framework intended to assist governmental bodies, policymakers, and urban planners in navigating the path toward achieving sustainable cities. Likewise, the proposed model provides policy implications for enacting and revising urban sector policies in developing regions, considering the fundamental themes of social sustainability. Eventually, this study contributes to implementing Sustainable Cities and Communities (SDG 11) in the 2030 Agenda for Sustainable Development, bridging the gap between urbanization and sustainable urban societies. Also, this model is a valuable tool for promoting socially sustainable urban development in developing regions.
Family tourism development in the new era of tourism: Korean tourists’ domestic trip preferences for accommodation, travel duration, destination, and natural environment
Authors: Lee Soyeun , Kim JooHyang , Han Heesup 
Published: October 2023

AbstractThis study identifies the main selection attributes of potential Korean domestic family tourists using a choice experiment (CE) and then figures out how much money they are willing to pay for each attribute. This paper uncovered that there are differences in preference patterns across income level and the presence of children. The family travelers preferred shorter travel times, two nights and 3 days for travel duration, resort/condominium, low media/SNS exposure places, and natural scenery or relaxing. In addition, a strong preference for natural scenery or relaxing induces the highest marginal-willingness-to-pay (MWTP) regardless of the income level and the presence of children. This study has academic significance as it presents the appropriate value estimation for each attribute through MWTP assessment, offering essential foundational data for establishing reasonable pricing for tourism products.

Published: October 2023

AbstractThis study combined various non-invasive and micro-invasive analytical techniques to investigate the production process of coffin plank paintings excavated from a Northern Wei tomb in Zhijiabao Village, Datong City, Shanxi Province. Fiber-optic reflectance spectroscopy, portable Raman spectroscopy, and portable X-ray fluorescence spectroscopy were employed for in-situ non-invasive detection of coffin panel paintings. On that basis, micro-samples in smaller amounts than that of previous studies of the same type were collected and analyzed through optical microscopy, confocal micro-Raman spectroscopy, and scanning electron microscopy-energy dispersive spectroscopy. The results showed that the studied coffin plank decoration was painted after applying a layer of yellow primer to the plank surface. Specifically, cinnabar was used as the red material, pararealgar was used as the yellow color, an indigo and orpiment mixture was used as the green substance, the blue pigment was most likely an indigo and lead white mixture, gypsum was used the white material, and carbon black was used as the black pigment. Notably, the studied coffin plank was painted with a mixture of inorganic and organic materials to present the green and blue colors. This study provided not only a scientific basis for the conservation and restoration of this artifact but also new information for the research on Northern Wei art history.
Using SOR framework to explore the driving factors of older adults smartphone use behavior
Authors: Huang Tianyang 
Published: October 2023

AbstractAt a time when the population is aging and the digital divide among older adults is becoming increasingly prominent, the research on the smartphone use behavior of the older adult in China is slightly insufficient. Therefore, this study aims to develop a smartphone acceptance model for older adults in China to predict the factors of their behavioral intention to use smartphones. Using Stimulus-organism-response (SOR) theory as the framework, planned behavior theory, self-efficacy theory and technology acceptance model as the theoretical basis, and employed a mixed quantitative and qualitative research approach to analyze the data from 244 older adults using structural equation modeling. The results show that technology anxiety, subjective norms, self-efficacy, perceived usefulness, facilitating conditions, and perceived ease of use had significant effects on the behavioral intention smartphones among older adults. In addition, perceived usefulness was directly influenced by subjective norms and perceived ease of use, facilitating conditions significantly influenced perceived ease of use and self-efficacy, and subjective norms and self-efficacy significantly affect technology anxiety. This study expanded the applicability of SOR framework, further expanded the technology acceptance model, and enriched the theory of smart phone use behavior of older adults users. The results of this study provide a valuable theoretical framework for the study on older adults users’ behaviors and have implications for the design and marketing of smartphones with high acceptancy from older adults.
A hydraulic energy flow within the moving Earth
Authors: Herrmann Friedrich , Pohlig Michael 
Published: October 2023

Abstract
We consider the Earth moving through empty space at 30 km s−1 (in the Sun’s frame of reference). Associated with this motion is a convective flow of kinetic and internal energy. Since there is high pressure inside the Earth, and since the Earth is moving, there is yet another ‘hydraulic’ energy flow. This latter is what this article is about. Although this energy flow is huge, it is not addressed in the textbooks. The reason is that for the explanation one needs a concept which is not introduced in traditional presentations of classical gravitation: the gravitomagnetic field. The corresponding theory, gravitoelectromagnetism, was formulated in 1893 by Heaviside in analogy to Maxwell’s theory of electromagnetism. We discuss the question of what are the sources and sinks of this hydraulic, non-convective energy flow. To answer the question, we need to study the energy flow density distribution within the gravitational field. In doing so, we will make some interesting observations. The energy flow within the field is twice as large as it should be to transfer the field energy from one side of the Earth to the other. The excess flow goes back through the matter of the Earth. Since our readers may not be familiar with Heaviside’s theory, we first treat the electromagnetic analogue of our problem and then translate the results to the gravitational situation.

The physical meaning of the norm of a four-vector is analysed, and Clausius definition of entropy variation is generalised to relativity. The classical description of the process is obtained in a moving lab by taking the low-speed limit in the four-vector fundamental equation. The formalism naturally incorporates the role of the laws of mechanics when analysing processes that are typically considered as purely thermodynamic.
Non-homogeneous pairing in disordered two-orbital s-wave superconductors

Abstract
We investigate the effects of non-magnetic disorder in a hybridized two-dimensional two-orbital s-wave superconductor (SC) model. The situation in which electronic orbitals overlap such that the hybridization

V

,
j

among them is antisymmetric, under inversion symmetry, was taken into account. The on-site disorder is given by a random impurity potential W. We find that while the random disorder acts to the detriment of superconductivity, hybridization proceeds to favor it. Accordingly, hybridization plays an important role in two-orbital models of superconductivity, in order to hold the long-range order against the increase of disorder. This makes the present model eligible to describe real materials, since the hybridization may be induced by pressure or doping. In addition, the regime from moderate to strong disorder reveals that the system is broken into SC islands with correlated local order parameters. These correlations persist to distances of several order lattice spacing which corresponds to the size of the SC-Islands.

Published: October 2023

Abstract
A highly electroactive bilayer composite film sensing interface of Prussian blue (PB)/gold nanoparticles-chitosan (AuNPs-CS) was modified on Au electrode through electrochemical deposition and coating method followed by integrating glucose oxidase (GOx) into the interfacial matrix to fabricate a high-performance glucose biosensor. The excellent electrocatalytic ability of the PB/AuNPs-CS composite film sensing interface for H2O2 was evaluated, which has a broad linear response of 0.01–7.95 mM, with a low detection limit (LOD) 0.269 μM and a high sensitivity of 511.82 μA·mM−1·cm−2. The enhanced electrocatalytic activity of this sensing interface for H2O2 is attributed to the protection from the network CS film to PB and the synergistic effect of PB and AuNPs. Consequently, an electrochemical biosensing interface was constructed with GOx immobilized as a model enzyme. The PB/GOx-AuNPs-CS biosensing nanocomposite film was capable of a fast steady-state response time (within 2 s) and high sensitivity to glucose with a wide linear range of: 0.025–2.00 mM (R
2 = 0.99), with a sensitivity of 40.41 μA·mM−1·cm−2 and a LOD of 1.62 μM; and 2.00–6.50 mM (R
2 = 0.98), with a sensitivity of 8.90 μA·mM−1·cm−2 and a LOD of 7.16 μM. The biosensor has good anti-interference and selectivity, which provides a promising wide linear range platform for clinical blood glucose detection in the future.
