Cooperation Between China and Russia in the Field of Environmental Protection in the Arctic: Current State and Prospects
Authors: Xinxin Fu
Published: June 2023

In the Arctic, social, economic and environmental issues require the region’s countries to work together to preserve the planet and improve the well-being of people living in harsh conditions. The region is warming twice as fast as the global average, ice and snow are melting, ecosystems are transforming, and indigenous and local cultures are struggling to adapt to the new conditions. Thus, the engagement of key international actors such as Russia and China in Arctic sustainable development goals is more than a platform for international partnerships for caring about the planet and humanity. In view of the above situation, the author uses the method of comparative analysis and induction to discuss topical issues of Chinese-Russian cooperation in the field of environmental protection in the Arctic. Particular attention is paid to such areas of cooperation as the development of international environmental law and participation in working groups on various environmental aspects; satellite navigation in the Arctic region, joint research, expeditions and training, as well as exchange of research equipment and data. In addition, emphasis is placed on Russian-Chinese programs in the field of underwater observation and hydroacoustics.
Are novel or locally adapted pathogens more devastating and why?: Resolving opposing hypotheses

There is a rich literature highlighting that pathogens are generally
better adapted to infect local than novel hosts, and a separate
seemingly contradictory literature indicating that novel pathogens pose
the greatest threat to biodiversity and public health. Here, using
Batrachochytrium dendrobatidis, the fungus associated with
worldwide amphibian declines, we test the hypothesis that there is
enough variance in novel host-pathogen outcomes to pose substantial risk
of pathogen introductions despite local adaptation being common. Our
continental-scale, common garden experiment and global-scale
meta-analysis demonstrate that local amphibian-fungal interactions
result in higher pathogen prevalence, pathogen growth, and host
mortality, but novel interactions led to strikingly variable
consequences with the greatest risk occurring when susceptible hosts and
virulent strains interacted. Thus, while most pathogen introductions are
benign, enough variance exists in novel host-pathogen outcomes that
moving organisms around the planet greatly increases the chance of
pathogen introductions causing profound harm.

Published: June 2023

Introduction: Functional endoscopic sinus surgery (FESS) has
become the gold standard for treating chronic rhinosinusitis (CRS), and
it is regarded as a relatively safe and effective technique. Orbital
complications of FESS have been reported for many years owing to the
close anatomical relationship between the paranasal sinuses and the
orbit. Accidental injury of the lamina papyracea (LP) during FESS, was
described in up to 5% of cases. Preventing complications begins with
preoperative planning and careful review of computed tomographic (CT)
scans. Methods: This was a multicentric national survey to
report any case of lamina papyracea defect (LPD) that was not reported
by radiologists. Multiple rhinologists from different provinces of Saudi
Arabia (SA) were invited to report any patient with such an incidence in
the last two years. patient-specific data were all included in this
study. Results: The data of 16 patients, 11 males and 5
females, were reviewed retrospectively. The median age at diagnosis was
37.4 years. The right side is the most prevalent location of LPD (8
patients, 50%), despite the fact that most cases (75%) had no history
of trauma or sinus surgery. Five patients had left-side LPDs and three
had bilateral LPDs. Conclusion: Injury to the LP is a
well-known avoidable complication of FESS. Careful and attentive review
of CT scan images pre-operatively and by the operating surgeon is of
utmost importance. This should always include the integrity and
configuration of the medial orbital wall and LP without depending on the
report of CT scans.
Double-Input Triple-Output Non-Isolated DC-DC Converter Based on Coupled-Inductor with High Stepped-Up Output Voltages
Authors: Saadatizadeh Zahra , Babaei Ebrahim , Hosseini seyyed hossein
Published: June 2023

This paper introduces a new non-isolated double-input
triple-output (DITO) high voltage gain DC-DC converter with a wide range
of applications, including hybrid voltage source systems, solar home
appliances, dc bus power distribution systems, and electrical vehicles
(EV). The proposed DITO converter interfaces two hybrid voltage sources
to supply three different output loads with varying voltage and power
levels. Compared to conventional converters of the same type, the
proposed DITO converter offers several advantages, including operation
for all duty cycles, integration of hybrid energy sources to transfer
power to multiple loads, high voltage conversion ratio for all three
output ports, a higher ratio of total voltage gain to total components
number, common grounded input and output DC ports, simultaneous DC
voltage regulation of three output ports by tuning separate controlling
parameters of duty cycles, an additional turn ratio of coupled inductors
to increase the voltage gain of output ports, and medium voltage stress
on switches. The proposed DITO converter utilizes a new single-switch
single-coupled-inductor DC-DC structure, which is analyzed and verified
through a prototype implementation for 25V and 30V input voltages and
210V, 330V, and 400V output voltages with a total power of 480W. The
experimental results confirm the simulation results and theoretical
analysis.

Authors: Zhu Jianbo
Published: June 2023

In this paper, we consider the existence and uniqueness of global solutions
for non-autonomous evolution equations with state-dependent nonlocal
conditions, in which the undelayed part admits an evolution operator. We
discuss the problems by utilizing theory of evolution operators, Schauder
fixed point theorem and Banach fixed point theorem. Some new results on
existence and uniqueness of solutions of the considered equation are
obtained on the infinite internal [0,+?). In the end, the obtained results
are applied to a class of non-autonomous heat equations with state-dependent
nonlocal conditions.

In this study, we construct q-analog C(q) of Catalan matrix and study the sequence spaces c0(C(q)) and c(C(q)) defined as the domain of q-Catalan matrix C(q) in the spaces c0 and c, respectively. We exhibit some topological properties, obtain Schauder bases and determine ?-, ?-, and ?-duals of the spaces c0(C(q)) and c(C(q)). Finally, we characterize certain class of matrix mappings from the spaces c0(C(q)) and c(C(q)) to the space ? = {??, c0, c, ?1} and give the necessary and sufficient conditions for a matrix operator to be compact.
A refinement of the Cauchy-Schwarz inequality accompanied by new numerical radius upper bounds
Authors: Al-Dolat Mohammed , Jaradat Imad
Published: June 2023

This present work aims to ameliorate the celebrated Cauchy-Schwarz inequality and provide several new consequences associated with the numerical radius upper bounds of Hilbert space operators. More precisely, for arbitrary a, b ? H and ? ? 0, we show that |?a,b?|2 ? 1 ? + 1 ?a??b?|?a, b?| + ?/?+1 ?a?2?b?2 ? ?a?2?b?2. As a consequence, we provide several new upper bounds for the numerical radius that refine and generalize some of Kittaneh?s results in [A numerical radius inequality and an estimate for the numerical radius of the Frobenius companion matrix. Studia Math. 2003;158:11-17] and [Cauchy-Schwarz type inequalities and applications to numerical radius inequalities. Math. Inequal. Appl. 2020;23:1117-1125], respectively. In particular, for arbitrary A, B ? B(H) and ? ? 0, we show the following sharp upper bound w2 (B*A) ? 1/2?+2 ?|A|2 + B|2?w(B*A)+ ?/2?+2 ?|A|4 + |B?4, with equality holds when A=B= (0100). It is also worth mentioning here that some specific values of ? ? 0 provide more accurate estimates for the numerical radius. Finally, some related upper bounds are also provided.
Oesophageal manometry and video-radiology in patients with systemic sclerosis: a retrospective study of its clinical value
Authors: Ipsen P , Egekvist H , Aksglaede K , Zachariae H , Bjerring P , Thommesen P.
Published: June 2023

The aim of this retrospective study was to evaluate the initial video-radiology and manometry in 40 consecutive patients with systemic sclerosis (n=21) or suspected systemic sclerosis (n = 19) in relation to oesophageal symptoms; and, furthermore, to evaluate the consequence of radiographic or manometric findings in the oesophagus on diagnosis and treatment. Evaluating oesophageal abnormalities in relation to diagnosis and treatment has, to our knowledge, not been reported before. Video-radiology together with manometry demonstrated oesophageal dysfunction in 80% of patients. Thirteen patients (33%) were asymptomatic in spite of identified motility abnormalities. Following the radiographic and manometric investigation, 9 patients (23%) had a change of diagnosis and, in 20 patients (50%), systemic treatment was instituted or intensified. The study confirms that both manometry and video-radiology are important for the identification of oesophageal motility abnormalities in patients with systemic sclerosis. Oesophageal symptom profiles alone do not predict abnormal findings.

Published: June 2023

Mucocutaneous diseases are common in HIV-infected patients. The aim of the present study was to determine the observed frequency of skin diseases and their prognostic significance for the progression of HIV infection. In a cohort of 150 HIV-infected patients diagnosed from 1986 to 1987 the number of mucocutaneous diseases, the CD4+ cell count, time to development of AIDS and survival time were registered for a period of 5 years. Eight patients were lost for follow-up. In the remaining 142 patients the number of mucocutaneous findings increased markedly during the observation period. The most frequent registered diseases and these with the highest increase were oral candidiasis, hairy leukoplakia, seborrhoeic dermatitis and herpes simplex. On average, 5.2 different diagnoses were registered per patient at the end of the follow-up period. The study showed that the total number of mucocutaneous diseases and the CD4+ cell count were significantly correlated to survival time and time to development of AIDS. The number of mucocutaneous diseases, like the CD4+ count, is an indicator of the immune system and the prognosis of HIV infection.

Authors: Abzhandadze Tamar , Lundström Erik , Buvarp Dongni , Eriksson Marie , Quinn Terence J. , Sunnerhagen Katharina S.
Published: June 2023

Objective: The primary objective was to develop a Swedish short version of the Montreal Cognitive Assessment (s-MoCA-SWE) for use  with patients with stroke. Secondary objectives were to identify an optimal cut-off value for the s-MoCA-SWE to screen for cognitive impairment and to compare its sensitivity with that of previously developed short forms of the Montreal Cognitive Assessment.Design: Cross-sectional study.Subjects/patients: Patients admitted to stroke and rehabilitation units in hospitals across Sweden.Methods: Cognition was screened using the Montreal Cognitive Assessment. Working versions of the s-MoCA-SWE were developed using supervised and unsupervised algorithms.Results: Data from 3,276 patients were analysed (40% female, mean age 71.5 years, 56% minor stroke at admission). The suggested s-MoCA-SWE comprised delayed recall, visuospatial/executive function, serial 7, fluency, and abstraction. The aggregated scores ranged from 0 to 16. A threshold for impaired cognition ≤ 12 had a sensitivity of 97.41 (95% confidence interval, 96.64–98.03) and positive predictive value of 90.30 (95% confidence interval 89.23–91.27). The s-MoCA-SWE had a higher absolute sensitivity than that of other short forms.Conclusion: The s-MoCA-SWE (threshold ≤ 12) can detect post-stroke cognitive issues. The high sensitivity makes it a potentially useful “rule-out” tool that may eliminate severe cognitive impairment in people with stoke.
LAY ABSTRACTStroke survivors have an increased risk of developing cognitive impairment, a common consequence of stroke. Therefore, many international guidelines recommend cognitive screening for all patients admitted to hospital with stroke. The Montreal Cognitive Assessment (MoCA) has been recommended as an appropriate cognitive test to be applied in stroke units. Although the administration of MoCA takes approximately 15 min, the screening can take longer in patients with acute stroke. Therefore, this study aimed to develop a Swedish short version of the Montreal Cognitive Assessment (s-MoCA-SWE) based on data from a large Swedish sample of acute and early subacute stroke survivors. The current study analysed data from 3,276 patients and suggest an s-MoCA-SWE that comprised the following tasks: delayed recall, visuospatial/executive function, serial 7, fluency, and abstraction. The s-MoCA-SWE could identify cognitive impairment in 97% of patients. In conclusion, s-MoCA-SWE has the potential to rule out severe cognitive impairment.
Stabilized reduced integration and sequentially linear analysis on the approximation of the non-linear behaviour of structures
Authors: Amezcua Rivera H. , Milián A.
Published: June 2023

En este artículo se propone una estrategia computacionalmente eficiente para la aproximación del comportamiento no-lineal de estructuras mediante el método de los elementos finitos. Esta propuesta se basa en la ejecución de una serie de análisis lineales en los que la resistencia de los elementos en los que se presenta el daño se degrada de manera secuencial complementándose con un esquema de integración numérica reducida estabilizada para elementos finitos sólidos. Así, la matriz de rigidez solo contiene información en un punto de integración y, en consecuencia, los esfuerzos se calculan en dicho punto. Del mismo modo, la estabilización posibilita que no solamente se utilice integración reducida en los elementos donde se asume que ocurrirá el daño, sino en todos los elementos, garantizando una mayor reducción del costo computacional. En este artículo se aplica esta estrategia de análisis no-lineal basada en análisis lineales secuenciales e integración reducida estabilizada a una serie de ejemplos tanto de validación como de aplicación en los que se discute la calidad en la aproximación y la eficiencia computacional alcanzada. Finalmente, se discuten algunos desarrollos futuros para la estrategia.

Shaping Southeast Asian Taste: Curry as Historical Evidences of Muslim Trade Networks in the Indian Ocean
Authors: Bambang Widyonarko
Published: June 2023

Though most spices originated from and were mostly consumed nowadays in areas in the Indian Ocean, discussion about the history of spices always started with European exploration in the 15th and 16th centuries. For these spiceproducing-and-consuming areas, such a Eurocentric view undermined their role in the spice route and gave them nothing but uneasy memory when remembering spice, because the majority of people there knew it only as a fortune looted by the Europeans. In these spice-producing areas, dishes similar to what modern society now identify as curry were found since the early modern period. By using historical methods and utilization of secondary sources like studies about the early modern economy and regional food history of Asia, this paper attempts to know more about the relationship between spices and people in the Indian Ocean, for I am sure that millennia aged contact between them must result from far more complex relation than just a relation between commodity and the people who cultivate and sell it. Scrutinizing curry resulted in a conclusion that spice masters of the Indian Ocean were neither spoiled cultivators nor lazy hosts. Curry was a happy memory of an era of economic boom, where people all over the Indian Ocean competitively took part in the expanding network of Muslim trade and profited greatly from the lucrative maritime spice trade.

Published: June 2023

The study area is located in the North-Eastern part of the Nile Delta, northern of Ismailia canal and western Suez Canal. It comprises an area of about 3,058.8 km2 (728,285.38 feddans). This work aims to identify the main physiographic units and its features, as well as emphasise the importance of combining soil taxonomy (2014) and WRB classification (2022) systems. Two main physiographic units were distinguished in the study area according to the previous studies, interpretation of satellite image and digital elevation model (DEM) as well as field observations; the first consists of fluvio-marine flats and the second river terraces which include the fluvial and deltaic origin. According to field morphological descriptions as well as chemical and physical analyses, representative profiles are classified by using both Soil Taxonomy and WRB systems. The current study is the third manuscript to emphasise the importance of using both systems together in order to obtain maximum possible characteristics of the earth. Below are examples that illustrate this importance. Soils of profile No. 4 which represent the fluvio-marine soils are classified according to soil taxonomy as follows: Typical Haplosalids, fine silty, mixed, thermic. While these soils are classified according to WRB as follows: Fluvic Sodic Solonchaks (Siltic/Loamy/Clayic, Chloridic, Evapocrustic, Ochric, Hypersalic). Soils of gypsiferous which represent soils of profile No. 6 are classified according to Soil Taxonomy as: Gypsic Aquisalids, loamy over sandy, mixed, thermic, whereas the application of the WRB system reveals the following: Fluvic Calcic Gypsic Sodic Gleyic Solonchaks (Loamic, Chloridic, Hypersalic).
Theoretical efficiency of the pulverising aerator – A case study based on Lake Swarzędzkie
Authors: Osuch Andrzej , Osuch Ewa , Rybacki Piotr , Herkowiak Marcin , Osuch Emilia
Published: June 2023

Lakes can be restored by the aeration method with the use of wind driven pulverising aerators. The method allows for moderate oxygenation of hypolimnion waters and it may be part of an integrated surface waters restoration system. The paper attempts to use the author’s method of maximum wind speeds to assess the volumetric flow of water through the aerator pulverisation mechanism. The study was conducted in 2018 in windy conditions of Lake Swarzędzkie. The introduction to the paper includes the characteristic of the lake and discusses the construction and operation of the wind driven pulverising aerator. Based on the maximum wind speed model, the theoretical capacity of the machine was calculated, which in the conditions of Lake Swarzędzkie was less than 111,500 m3 per year. Based on maximum wind speeds, the method of assessing the efficiency of the wind driven pulverising aerator is suitable for determining the volumetric flow rate of the pulverisation unit. This can significantly facilitate the planning of water reservoir restoration.
Efficient removal of imidacloprid pesticide by two eco-friendly activated carbons
Authors: Mohammad Somaia Gaber , El-Refaey Ahmed A.
Published: June 2023

In this study, the removal of imidacloprid (IMD) pesticide onto activated carbon produced from nut shells of hazelnut (HAC), and walnut (WAC) has been investigated. The prepared activated carbons were characterised by total carbon, nitrogen and hydrogen content, surface areas and pore volume. Fourier-transform infrared (FTIR), and scanning electron microscopy (SEM) were studied before and after adsorption experiments. Effects of adsorbent dose (0.02–0.2 g), contact time (10–120 min), initial imidacloprid concentration (10–100 mg∙dm –3), and pH (1–8), and temperatures (25–50°C) on the removal of IMD pesticide by HAC and WAC in the batch mode were studied. The removal percentage of imidacloprid pesticide by HAC and WAC was 93.79% and 94.72%, respectively. The study showed that the pseudo-second-order kinetics model fitted well for both activated carbons. Moreover, adsorption isotherm results were evaluated using Freundlich, Langmuir and Temkin isotherm models. The adsorption results correlated well with the Langmuir isotherm model ( R2 = 0.987 and 0.964) with maximum adsorption capacities of 76.923 and 83.333 mg∙g –1 for HAC and WAC, respectively, and an equilibrium time within 120 min. The nature of the adsorption of imidacloprid pesticide onto HAC and WAC is exothermic, spontaneous and physical in nature. The two prepared activated carbons (HAC, WAC) were successfully regenerated for three cycles and could be used as an effective and low-cost adsorbent for the removal of IMD pesticide from aqueous solutions. The production of the activated carbons of HAC and WAC will provide minimisation of these wastes in the environment.
Multimodal sentiment analysis for social media contents during public emergencies
Authors: Fan Tao , Wang Hao , Wu Peng , Ling Chen , Ahvanooey Milad Taleby
Published: June 2023

Purpose

Nowadays, public opinions during public emergencies involve not only textual contents but also contain images. However, the existing works mainly focus on textual contents and they do not provide a satisfactory accuracy of sentiment analysis, lacking the combination of multimodal contents. In this paper, we propose to combine texts and images generated in the social media to perform sentiment analysis.

Design/methodology/approach

We propose a Deep Multimodal Fusion Model (DMFM), which combines textual and visual sentiment analysis. We first train word2vec model on a large-scale public emergency corpus to obtain semantic-rich word vectors as the input of textual sentiment analysis. BiLSTM is employed to generate encoded textual embeddings. To fully excavate visual information from images, a modified pretrained VGG16-based sentiment analysis network is used with the best-performed fine-tuning strategy. A multimodal fusion method is implemented to fuse textual and visual embeddings completely, producing predicted labels.

Findings

We performed extensive experiments on Weibo and Twitter public emergency datasets, to evaluate the performance of our proposed model. Experimental results demonstrate that the DMFM provides higher accuracy compared with baseline models. The introduction of images can boost the performance of sentiment analysis during public emergencies.

Research limitations

In the future, we will test our model in a wider dataset. We will also consider a better way to learn the multimodal fusion information.

Practical implications

We build an efficient multimodal sentiment analysis model for the social media contents during public emergencies.

Originality/value

We consider the images posted by online users during public emergencies on social platforms. The proposed method can present a novel scope for sentiment analysis during public emergencies and provide the decision support for the government when formulating policies in public emergencies.

Published: June 2023

A manufacturing company in Indonesia creates sports shoes under the particular brand is still having trouble with a number of issues, including late raw material deliveries from suppliers, production that falls short of expectations, and delayed product delivery to customers. The performance of the supply chain must therefore be measured. The study assesses the importance of supply chain performance within the organization and offer recommendations for improvement to raise supply chain performance within the organization. Analytical Hierarchy Process (AHP) and Supply Chain Operation Reference (SCOR) 12.0 are used to gauge supply chain performance. The outcomes revealed that supply chain performance’s value at 77,539. Improvements are required to increase the company's supply chain performance because three KPIs have low weights, the percentage of orders for raw materials that are delivered on time, the price of purchasing raw materials, and the cost of returning item. Corrective actions carried out by the company include arranging materials neatly in the warehouse, providing sufficient lighting, maintaining air humidity, keeping hands clean when holding shoes, checking glue on the upper shoes so that open bonding does not occur, giving penalties to suppliers who are late, and giving training to reduce material damage.

Published: June 2023

This study aimed to investigate the association between development density and housing prices in Seoul, utilizing a machine learning driven hedonic price model. The model employed actual transaction data of high-rise condominiums (apartments) spanning from January 2019 to December 2021. The study employed CatBoost algorithm and eXplainable AI techniques (SHAP) to explore the non-linear relationships between floor area ratio(FAR) and housing prices. The findings revealed that overall FAR had a negative relationship with housing prices for both general apartments and mixed-use development. However, the negative impact of FAR was relatively small in large-scale development. Furthermore, the negative impact of FAR may not be significant in some high-end mixed-use development. These findings imply the importance of proposing appropriate site plans to ensure a desirable residential environment when high-density development is necessary.

The location of the university academic staff in two clearly identified contexts, the academic and the unionist, constitutes one of the causes, among many others, of the current educational problem. The origins and causes of unionism and its awareness on the part of academic staff working in higher education institutions force us to review history since the birth of university unionism, almost six decades ago. This work aims to present information that allows a clear picture of how unionism began in higher education institutions, the problems it went through until it achieved its consolidation and its role in labor relations.
