Vegetable oils like extra virgin olive oil, Moringa oleifera oil, sunflower, and corn oils are regularly used for cooking purposes in the Arabian region. Additionally, the consumption of fried food is becoming increasingly popular in this region. The current study is to find out how temperature affects oils without using food of any kind. The fatty acid and antioxidant profiles of these four vegetable oils (extra virgin olive oil, Moringa oleifera oil, sunflower oil, and corn oil) have been investigated in terms of temperature during deep-frying and re-heating. In this process, an electric fryer is used for deep-frying and reheating oil without adding any kind of food. The collected vegetable oil samples were heated for six hours on five different time periods to a temperature of up to 175 ± 5 °C, and the fatty acid profiles were analysed before and after each cycle by using gas chromatography and were characterized by means of UV and FTIR techniques as well. The composition of oil fatty acids is more affected by re-heating than by deep-frying, as the results indicated. The antioxidant activity of the different oils was assessed using the diphenyl-1-picrylhydrazyl (DPPH) scan; the findings revealed that, whereas antioxidant activity dropped sharply in re-heated oils, it did so gradually for deep-frying samples.
OS IMPACTOS DA AUSÊNCIA DE UM REGIME DE TRANSIÇÃO DO NOVO MARCO DO SANEAMENTO BÁSICO PERANTE AS FORMAS DE PRESTAÇÃO DE SERVIÇOS
Authors: Senna Lais Ribeiro
Published: October 2023

O presente artigo tem por objetivo demonstrar as particularidades da prestação de serviços de saneamento básico as diversas formas contratuais do setor, diante de alterações promovidas pelo Novo Marco do Saneamento Básico. O Direito tem como mecanismo de garantia da segurança jurídica a adoção de regimes de transição em situações em que a legislação realiza profundas alterações sobre determinado setor. E, ainda que tenha sido o caso do Novo Marco, ao fazê-lo, o regime de transição deixou de ser instituído a partir de sua publicação, causando impasses no setor e sendo necessária a publicação de Decretos três anos mais tarde que, embora tenham tido o intuito de conferir uma certa transição de regimes, além de terem sido editados após certo intervalo, não o fazem com o detalhamento necessário. Tudo isso se torna um grande empecilho à universalização dos serviços, na medida que impacta diretamente sobre a previsibilidade e segurança jurídica do setor.

Published: October 2023

Introduction

Vascular surgery is a recognised surgical subspecialty covering an array of circulatory conditions predominately affecting geriatric and diabetic patients. As such, a wide breadth of clinicians will see patients with vascular pathologies, but it is unclear how detailed their knowledge base is. Key to this is the education of medical students, which has been poorly documented during undergraduate training in the UK. VENUM aimed to establish students' perceptions of vascular surgery and their confidence in performing vascular objective structured clinical examination (OCSE) skills.

Methods

During the academic year of 2022/2023, final-year medical students were invited to complete a JISC survey (collaborative authorship). Seventy-seven research leads were recruited to disseminate the survey. Quantitative and thematic analysis was used to assess the data.

Results

In total, 240 final-year medical students completed the survey (54% female; 26 medical schools represented). Forty-five per cent of students reported never having had a vascular placement, 24% had never completed a vascular-focused clinical examination and 26% reported low confidence in performing ankle brachial pressure index measurement. An assessment of peripheral arterial disease morbidity was answered correctly in 17% of respondents compared with 92% for angina (chi-square test p<0.001). Students perceived the specialty to be non-inclusive and that early exposure to vascular surgery was required for better engagement with the specialty.

Conclusion

Students have experienced little exposure to vascular surgery. This may affect future recruitment to vascular surgery and overall knowledge of vascular conditions in UK-trained doctors, which may affect long-term patient management.

Human security as an element of the concept of sustainable development in international law
Authors: Such-Pyrgiel Małgorzata , Gołębiowska Anna , Prokopowicz Dariusz
Published: October 2023

Objectives

The most popular definition of sustainable development is contained in the Report of the Brundtland Commission of 1987, according to which “sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs”. Although this definition is widely accepted, it still requires further discussion, which is the subject of the present study.

Material and methods

For the purposes of this article, research was carried out on the broadly defined issues of sustainable development, the origin and importance of the Sustainable Development Goals, the essence of sustainability in the context of social, normative, economic, environmental, climate aspects as well as human rights, etc. The research also concerned the issue of key determinants of human security as an element of the concept of sustainable development. The method of analysis of literature sources, comparative analysis of the examined determinants of sustainable development in international terms and analysis of the synthesis of various individual, key aspects of sustainable development...

Results

Research findings are included in the text of the article. The face of the principle of sustainable development is different, depending on the place, in which it is carried out. Its constituents, that is social and economic development with concurrent preserving of the environment, are differently treated in developed countries and in developing ones.

Conclusions

This variety of approaches affects the range of the understanding of the principle. It seems that this aspect of the principle should prevail that decides about the environmental protection - as the principle of sustainable development allows ensuring intergenerational equity in access to natural environment resources.
Cultural construction of the body – risks and perspectives
Authors: Nawrocka Martyna , Stradomska Marlena Wanda
Published: October 2023

The aim of this paper is to indicate the possible consequences of the intensification of dietary, cosmetic and medical interference in the human body. Nowadays, creation or construction of identity takes place largely through modifications of the human body. Thus, the body ceases to be the domain of solely biology, and becomes dependent on culture and fashion. Transforming the body and controlling it through diets and other regimes is seen as pro-social and even morally correct. At the same time, body modifications serve as a medium for the individual to communicate his attitude and his inner self to the world. While some of these methods may be or appear to be helpful, others are associated with a number of serious consequences, such as self-harm, anorexia or orthorexia. The article aims to present the way in which culture shapes and transforms the body, as well as the possible consequences - both positive and negative

Prezentowany esej jest napisany w oparciu o studia Autora z różnych okresów rozwoju Wspólnot Europejskich. Jego cel to poszukiwanie podstawowych elementów rozwoju i stabilności państwa w warunkach globalizacji i członkostwa w Unii Europejskiej. Poszukując mechanizmów napędowych państwa wskazać trzeba przede wszystkim na wolną działalność gospodarczą oraz racjonalną gospodarkę samorządową (w wersji gminnej i regionalnej). To one właśnie są niedoceniane przez państwo, gdy zmierza do centralizacji zarządzania i ubezwłasnowolnienia samorządów w celu zwiększenia „siły państwa”, a w istocie władzy polityków, którzy niszczenie demokracji uznają za szybki „sukces.” Metoda analizy stosowana w tekście to konfrontacja tradycyjnej doktryny państwa na pograniczu autorytaryzmu stale obecnej w Polsce do roku 1989 z nową doktryną uwspólnotawiania państw. Najlepszą gwarancją która zapobiega starym i nowym zagrożeniom degeneracją funkcji państwowych jest obecnie prawo unijne z zestawem jego cech i środków egzekucji. Polska Konstytucja szeroko otwiera się na tę metodę wzmacniania państwa i prawa.
Real-timing processing of fiber bundle endomicroscopy images in Python using PyFibreBundle
Authors: Hughes Michael R.
Published: October 2023

Fiber imaging bundles allow the transfer of optical images from
place-to-place along narrow and flexible conduits. Traditionally used
extensively in medical endoscopy, bundles are now finding new
applications in endoscopic microscopy and other emerging techniques.
PyFibreBundle is an open-source Python package for fast processing of
images acquired through imaging bundles. This includes detection and
removal of the fiber core pattern by filtering or interpolation, and
application of background and flat-field corrections. It also allows
images to be stitched together to create mosaics and resolution to be
improved by combining multiple shifted images. This paper describes
the technical implementation of PyFibreBundle and provides example
results from three endomicroscopy imaging systems: color transmission,
monochrome transmission, and confocal fluorescence. This allows
various processing options to be compared quantitatively and
qualitatively, and benchmarking demonstrates that PyFibreBundle can
achieve state-of-the-art performance in an open-source package. The
paper demonstrates core removal by interpolation and mosaicing at over
100 fps, real-time multi-frame resolution enhancement and the first
demonstration of real-time endomicroscopy image processing, including
core removal, on a Raspberry Pi single board computer. This
demonstrates that PyFibreBundle is potentially a valuable tool for the
development of low-cost, high-performance fiber bundle imaging
systems.
Bevacizumab promotes tenogenic differentiation and maturation of rat tendon-derived cells in vitro
Authors: Kusaba Yohei , Kumagai Ken , Ishikawa Kimi , Choe Hyonmin , Ike Hiroyuki , Kobayashi Naomi , Inaba Yutaka
Published: October 2023

Previous work suggested that tenogenic differentiation of tendon stem/progenitor cells (TSPCs) was suppressed by upregulated expression of the angiogenic marker vascular endothelial growth factor (VEGF). The purpose of this study was to test the hypothesis that anti-VEGF antibody, bevacizumab, promotes in vitro tenogenic differentiation and maturation of two distinct types of TSPCs, tendon proper-derived cells (TDCs), and paratenon-derived cells (PDCs) originating from rat Achilles tendon. TDCs and PDCs were isolated from the tendon proper and the paratenon of rat Achilles tendons. TDCs and PDCs were cultured for 3 days on plates with or without VEGF. TDCs and PDCs were also cultured in collagen gel matrix, and the blocking effect of VEGF was examined by the addition of 100 ng/mL of bevacizumab. Effects of bevacizumab on tenogenic differentiation were assessed using real-time PCR, immunofluorescent staining, and western blotting. VEGF significantly attenuated expression of the Tnmd gene in both PDCs and TDCs (P<0.05). Expressions of the Scx, Tnmd, and Col1a1 genes were significantly upregulated by the addition of bevacizumab (P<0.05). Immunofluorescent staining showed that the percentage of tenomodulin-positive PDCs and TDCs was significantly higher with bevacizumab treatment than in control cultures (P<0.05). Western blotting showed that bevacizumab suppressed pVEGFR-2 protein expression in both PDCs and TDCs. Bevacizumab promoted the in vitro tenogenic differentiation and maturation of two distinct TSPCs derived from rat Achilles tendon. Since the previous studies demonstrated that TSPCs have a potential to contribute to tendon repair, attenuating VEGF levels in TSPCs by administration of bevacizumab is a novel candidate therapeutic option for promoting tendon repair.
Levodopa-induced dyskinesia in early-onset Parkinson’s disease (EOPD) associates with glucocerebrosidase mutation: A next-generation sequencing study in EOPD patients in Thailand

Published: October 2023

Background

With the benefit of using next-generation sequencing (NGS), our aim was to examine the prevalence of known monogenic causes in early-onset Parkinson’s disease (EOPD) patients in Thailand. The association between clinical features, such as levodopa-induced dyskinesia (LID), and genotypes were also explored.

Method

NGS studies were carried out for EOPD patients in the Tertiary-referral center for Parkinson’s disease and movement disorders. EOPD patients who had LID symptoms were enrolled in this study (n = 47). We defined EOPD as a patient with onset of PD at or below 50 years of age. LID was defined as hyperkinetic movements including chorea, ballism, dystonia, myoclonus, or any combination of these movements resulting from levodopa therapy, which could be peak-dose, off-period, or diphasic dyskinesias.

Results

Pathogenic variants were identified in 17% (8/47) of the Thai EOPD patients, of which 10.6% (5/47) were heterozygous GBA variants (c.1448T>C in 3 patients and c.115+1G>A in 2 patients), 4.3% (2/47) homozygous PINK1 variants (c.1474C>T) and 2.1% (1/47) a PRKN mutation (homozygous deletion of exon 7). The LID onset was earlier in patients with GBA mutations compared to those without (34.8±23.4 vs 106.2±59.5 months after starting levodopa, respectively, p = 0.001). LID onset within the first 30 months of the disease was also found to be independently associated with the GBA mutation (odds ratio [95% confidence interval] = 25.00 [2.12–295.06], p = 0.011).

Conclusion

Our study highlights the high prevalence of GBA pathogenic variants in Thai patients with EOPD and the independent association of these variants with the earlier onset of LID. This emphasizes the importance of genetic testing in this population.
Monitoring the reproductive number of COVID-19 in France: Comparative estimates from three datasets
Authors: Bonaldi Christophe , Fouillet Anne , Sommen Cécile , Lévy-Bruhl Daniel , Paireau Juliette
Published: October 2023

Background

The effective reproduction number (Rt) quantifies the average number of secondary cases caused by one person with an infectious disease. Near-real-time monitoring of Rt during an outbreak is a major indicator used to monitor changes in disease transmission and assess the effectiveness of interventions. The estimation of Rt usually requires the identification of infected cases in the population, which can prove challenging with the available data, especially when asymptomatic people or with mild symptoms are not usually screened. The purpose of this study was to perform sensitivity analysis of Rt estimates for COVID-19 surveillance in France based on three data sources with different sensitivities and specificities for identifying infected cases.

Methods

We applied a statistical method developed by Cori et al. to estimate Rt using (1) confirmed cases identified from positive virological tests in the population, (2) suspected cases recorded by a national network of emergency departments, and (3) COVID-19 hospital admissions recorded by a national administrative system to manage hospital organization.

Results

Rt estimates in France from May 27, 2020, to August 12, 2022, showed similar temporal trends regardless of the dataset. Estimates based on the daily number of confirmed cases provided an earlier signal than the two other sources, with an average lag of 3 and 6 days for estimates based on emergency department visits and hospital admissions, respectively.

Conclusion

The COVID-19 experience confirmed that monitoring temporal changes in Rt was a key indicator to help the public health authorities control the outbreak in real time. However, gaining access to data on all infected people in the population in order to estimate Rt is not straightforward in practice. As this analysis has shown, the opportunity to use more readily available data to estimate Rt trends, provided that it is highly correlated with the spread of infection, provides a practical solution for monitoring the COVID-19 pandemic and indeed any other epidemic.
‘It is just a tweet … do not take it seriously!’ Humour posts on Twitter during coronavirus: The case of Kuwait
Authors: Dashti Ali A. , Murad Husain A. , Al-Kandari Ali , Dashti Ahmad
Published: October 2023

The uncertainty of the COVID-19 virus outbreak triggered chaos, panic and fear worldwide. During the outbreak, many humorous posts tweeted and retweeted addressed the virus with a laugh. Humour is a way to escape reality, but at the same time it may have negative outcomes. In Kuwait, many such posts spread on social media, especially Twitter. They reduced panic, educated the public or made people ignore the seriousness of the pandemic. This study investigates the negative implications of using humorous text, images and video messages on Twitter. A qualitative discourse analysis of 907 humorous texts, images and videos posted on Twitter during the crisis revealed that humorous posts may foster negative attitudes concerning sectarianism, tribalism, racism, sexism and hatred. Interestingly, humorous posts in less emotionally charged categories, such as sports, family and children, also include many negative connotations and denotations. This study is unique in addressing an understudied area; humour on social media in the Arab and Gulf region. Its findings show that humorous posts can produce negative outcomes and cause fear and hatred in society. There may be a need for self-censorship and moral behaviour to prevent social tension. The notion that jokes are only jokes and people should not be offended may have unforeseen negative repercussions.
Coumarin Imidazolone Hybrid as Inhibitor of Topoisomerase Type II and Hsp90 and as Potent Antimicrobials
Authors: Peddaboina Usha Rani , SADHULA ANITHA , Anisetti Ravinder Nath
Published: October 2023

In present study, coumarin imidazolone hybrids were synthesized on the basis of the molecular docking analysis of the compounds (11a-h) by using PyRx 0.8 software. The molecules docking studies were performed against the targets Hsp90 and human type IIA DNA topoisomerase and compared the same with standard drugs fluconazole and doxorubicin. Among all the compounds 11d (-12.7 kcal/mol) and 11f (-12.4 kcal/mol) showed good binding affinity towards human Hsp90 and 11d (-11.5 kcal/mol) and 11e (-11.4 kcal/mol) showed good binding affinity against human type IIA DNA topoisomerase. Based on the positive results a series of eight novel titled compounds (1-(4-(4-(arylidene)-5-oxo-2-phenyl-4,5-dihydro-1H-imidazol-1-yl)phenyl)ethylidene)-2-oxo-2H-chromene-3- arbohydrazides (11a-h) have been prepared by the method of condensation of 1-(4-acetylphenyl)-4-arylidene-2-phenyl-1H-imidazol- (4H)-ones (5a-h) with 2-oxo-2H-chromene-3-carbohydrazide (10). Characterization of the synthesized compounds were conducted by FT-IR, 1H NMR, 13C NMR, mass spectral studies and screened for their antioxidant, anticancer and antimicrobial activities. The compounds were analyzed for physico-chemical and pharmacokinetic properties of all the compounds showed good to moderate properties.
Design, Synthesis, Evaluation of Antitubercular and Antioxidant Activity of Isoxazoline Derivatives Derived from Novel Chalcone Intermediates
Authors: BASAK SUSMITA , BHAT K. ISHWAR
Published: October 2023

Tuberculosis (TB), a bacterial infection caused by Mycobacterium tuberculosis (M-TB) is a fatal disease associated with a high degree of mortality. Present work involved synthesis of a series of novel isoxazoline derivatives (ISOA1-ISOA8) the new antitubercular agents using newly synthesized chalcones (CHL1-CHL8). This was done by subjecting the chalcones to a reaction with hydroxylamine hydrochloride in presence of acetic acid and sodium acetate. The structure of the synthesized compounds was elucidated by IR, 1H NMR and mass spectra. In silico studies of isoxazoline were performed for antitubercular activity by using an enoyl acyl carrier protein (EACP) reductase enzyme. Compound ISOA4 exhibited the best interaction among all these compounds having a docking score of -5.94 compared to standard drug pyrazinamide -6.1. Using in vitro models, purified compounds were tested for their antioxidant and antitubercular properties. Compound ISOA5 showed a significant antioxidant activity compared to ascorbic acid as a standard drug. This study claims new isooxazolines to possess high antioxidant and antitubercular potential, however they must be evaluated for preclinical and clinical significance.
Case Report - Trauma Induced Vernet’s Syndrome
Authors: Sai Sri Hari Rao Nutakki  , Abhishek Kankipati  , Sujana Gogineni  , Vamsi Krishna Kotagiri
Published: October 2023

Trauma induced Vernet’s syndrome is a rare presentation and very few case reports exist in medical literature. Here we report a 40-year-old male with no significant medical history who presented with clinical features of right IX, X, and XI cranial nerve palsy after trauma to the neck and was diagnosed with right internal jugular vein thrombosis on imaging causing compression and symptoms. Patient symptomatically improved with anti-coagulation and was advised regular follow-up.

This case report emphasizes on the need for identifying trauma induced thrombosis as one of the uncommon causes of Vernet’s syndrome with better prognosis and the need for early imaging techniques in such cases.

The jugular foramen-crossing IX, X, and XI cranial nerves are paralyzed in Vernet syndrome. The posterolateral sulcus of the medulla oblongata is where the glossopharyngeal nerve, vagus nerve, and spinal accessory nerves emerge. They then travel via the basal cistern before leaving the skull by the jugular foramen.[1] Primary tumours like paraganglioma, meningioma, and schwannoma, metastatic tumours at the base of the skull, inflammation like meningitis and malignant otitis external, sarcoidosis, Guillain-Barre syndrome, vascular events like dissection, thrombosis, or aneurysm, and trauma are the main causes of Vernet syndrome.

Vernet syndrome caused by trauma is incredibly rare and is typically brought on by penetrating trauma or fractures impacting the posterior skull base. Approximately 30 cases of Jugular foramen syndrome caused by a fracture in the jugular foramen area have been documented to date.[2,3] Only one posttraumatic Vernet case without a fracture has, however, been documented so far,[4] and this is one of them.

Volume changes measurement of elastomers using 3D DIC
Authors: Kotlánová Barbora , Rusnáková Soňa , Ogunleye Raphael Olabanji , Javořík Jakub
Published: October 2023

The presented research aims at measuring the volume changes of elastomers using digital image correlation (DIC) in the 3D configuration (stereo DIC). The deformation measurement method in stereo configuration was applied during the mechanical testing of two types of test specimens (dumbbells, cylinders) in uniaxial tension. In this configuration, two cameras were used. The test specimens were measured up to a specified strain value, and the measured data were used to obtain the strain dependence of Poisson’s ratio and the bulk modulus, which are crucial for hyperelastic models. The measurement results reveal that the stereo DIC method provides relatively less scattered data in the low-strain regions for dumbbell-shaped test specimens and is suitable for measuring various test specimen shapes.
Experimental validation of motion sensor Physilog®5 applied to shoulder joint
Authors: Krivošej Jan , Garanová Krišťáková Jana , Daniel Matej , Šika Zbyněk
Published: October 2023

The main motivation of this paper is to verify the idea of using the Physilog®5 unit for the patients with shoulder movement difficulties. The attached sensor to the patient’s arm then measures motion during which the patient should follow certain paths. Finally, if a patient has difficulty with motion requirements, some typical pattern for their problem should emerge. By analysing these patterns, a database of typical problems could be created, which could assist doctors in determining a patient’s diagnosis.The experiment is focused on Physilog® concerning the 5th generation. The goal is to experimentally identify and verify the performance of this generation during relatively large motions of the upper limb. For this purpose, an experimental stand representing spherical joint with an accurate absolute position sensing is assembled and calibrated. Subsequently, the three Physilog®5 sensors are mounted on this stand at different positions.

Published: October 2023

Long-term stability of the tissue product in terms of mechanical parameters is a key factor for its expiration date. For the investigation of storage effects on the cartilage tissues the experimental mechanical loading test combined with XCT scanning for the irregular shape inspection was performed. The samples were preserved according to three different protocols using the deep-freezing and two types of saline solution preservation. The stability of the biomechanical parameters was tested within annual intervals. All samples were subjected to uni-axial compression loading using the in-house developed compact table top loading device in displacement-driven mode. Based on the measurements, the results are represented in the form of stress-strain curves and quantified as elastic modulus and ultimate compression stress. It can be concluded that no significant difference was found in neither the mechanical properties of the samples nor in the effects of each preservational method.

Published: October 2023

Introduction: Migration affects people’s lives, including their behaviours which impact both physical and mental health. Anxiety and depressive symptoms in migrants have been linked to negative physical and mental health outcomes associated with eating behaviour. This study aimed to analyse the mediating impact of positive and negative affect on the relationship between anxiety and depressive symptoms and emotional eating in migrants. Method: A sample of 922 Colombian migrants in Chile participated in the study. The Beck Anxiety Inventory, Beck Depression Inventory-II, Positive and Negative Affect Schedule, and the Dutch Eating Behaviour Questionnaire were used for data collection. Mediation analysis was conducted using structural equation models. Results: Anxiety and depression correlated positively. Anxiety presented positive results on negative affect and emotional eating and negative results on positive affect. Depression had positive impacts on negative affect and emotional eating and negative impacts on positive affect. Only negative affect presented significant positive results on emotional eating. Only negative affect presented a specific and statistically significant indirect influence on anxiety and emotional eating. Positive affect and negative affect jointly presented a total and statistically significant indirect effect between anxiety and EE and between depression and emotional eating. Conclusions: This study provides evidence of how negative affect mediates the relationship between anxiety and depressive symptoms and emotional eating.

Introducción: promover la conducta intraemprendedora es vital en cualquier organización, incluidas las del contexto educativo. Esta conducta se caracteriza por buscar oportunidades, actuar de forma proactiva para aprovechar esas oportunidades, así como adaptarse al entorno y actuar de forma innovadora. Asimismo, si los docentes quieren enseñar emprendimiento a los estudiantes, deben actuar como modelos de rol mostrando un comportamiento innovador, basado en la acción y la experiencia en el desarrollo de nuevos proyectos en el ámbito educativo. Con el objetivo de profundizar en el intraemprendimiento docente, el presente estudio examina empíricamente la influencia de la identificación organizacional en el comportamiento intraemprendedor docente y el papel mediador que puede desempeñar el work engagement en esa relación. Método: se utilizó un modelo de ecuaciones estructurales con la técnica de mínimos cuadrados parciales que permite analizar los datos que reportaron en un cuestionario 234 docentes (63% mujeres; Medad = 45 años) pertenecientes a varios centros educativos, mayoritariamente públicos y del sur de España (Andalucía). Resultados: los resultados muestran que existe una relación positiva entre la identificación organizacional y el work engagement y que, además, ambos influyen de forma positiva en el intraemprendimiento. Se confirma que la relación entre identificación organizacional e intraemprendimiento está totalmente mediada por el work engagement.

Authors: Radha Huda M. , Abdul Hassan Alia K. , Al-Timemy Ali H.
Published: October 2023

Amputation of the upper limb significantly hinders the ability of patients to perform activities of daily living. To address this challenge, this paper introduces a novel approach that combines non-invasive methods, specifically Electroencephalography (EEG) and Electromyography (EMG) signals, with advanced machine learning techniques to recognize upper limb movements. The objective is to improve the control and functionality of prosthetic upper limbs through effective pattern recognition. The proposed methodology involves the fusion of EMG and EEG signals, which are processed using time-frequency domain feature extraction techniques. This enables the classification of seven distinct hand and wrist movements. The experiments conducted in this study utilized the Binary Grey Wolf Optimization (BGWO) algorithm to select optimal features for the proposed classification model. The results demonstrate promising outcomes, with an average classification accuracy of 93.6% for three amputees and five individuals with intact limbs. The accuracy achieved in classifying the seven types of hand and wrist movements further validates the effectiveness of the proposed approach. By offering a non-invasive and reliable means of recognizing upper limb movements, this research represents a significant step forward in biotechnical engineering for upper limb amputees. The findings hold considerable potential for enhancing the control and usability of prosthetic devices, ultimately contributing to the overall quality of life for individuals with upper limb amputations.

A novel slotted dumbbell-shaped dielectric resonator antenna with enhanced bandwidth for C-band and 5G sub-6 GHz applications
Authors: Chandra Ravi , Upadhyay Dileep Kumar
Published: October 2023

This manuscript presents a novel aperture-coupled fed slotted dumbbell-shaped (SDS) dielectric resonator antenna (DRA) with enhanced bandwidth for 5G sub-6 GHz, short-range wireless communications, and C-band applications. The DRA is excited by HEM11δ
mode. The proposed SDS-DRA is designed by assembling the four frustums of conical DRAs with the base and apex of one on top of another. The measured operating frequency of SDS-DRA is from 3.5 GHz to 9.6 GHz (impedance bandwidth of 93.1 %). The SDS-DRA shows a peak gain of 9.7 dBi in the operational frequency range, with an average peak gain of 6.02 dBi. The antenna’s average radiation efficiency is found to be 84.6 %. The proposed SDS-DRA produces omnidirectional-like radiation patterns with significantly low cross-polarization in the broadside direction. The size (l × w × h) of the proposed SDS-DRA is 1.55λ

Spatial evolution of coastal environmental enterprises: An exploration of driving factors in Jiangsu Province
Authors: Wu Xiaotong , Zhou Yang , Song Yiming , Qian Wanliang
Published: October 2023

This article presents an in-depth analysis of the spatial and temporal evolutionary characteristics of the environmental protection industry in Jiangsu Province and analyzes the dynamics of changes in the spatial pattern of the environmental protection industry as a whole using spatial visualization methods. Attribute data of environmental protection enterprises in Jiangsu Province from 2000 to 2022 were selected for this article, with spatial analysis methods. From 2000 to 2005, the industry expanded to include Suzhou, Changzhou, and other areas, forming a multi-core pattern, supported by a Moran’s I value of −0.049837. This clustering trend continued from 2006 to 2010, with Moran’s I values of −0.115285 in 2011–2015 and −0.117398 in 2016–2022. By 2022, new clusters emerged in the coastal areas of Xuzhou, Yancheng, and Nantong, reflecting industry growth. By detecting with multiple factors, it is found that such pattern evolution is a result of a combination of factors, which is mainly influenced by environmental and employment factors in the early stages of development, while also significantly driven by market factors in the later stages of development as the dynamics of the spatial pattern continue to evolve with the economy.
Background check: cross-cultural differences in the spatial context of comic scenes
Authors: Atilla Fred , Klomberg Bien , Cardoso Bruno , Cohn Neil
Published: October 2023

Cognitive research points towards cultural differences in the way people perceive and express scenes. Whereas people from Western cultures focus more on focal objects, those from East Asia have been shown to focus on the surrounding context. This paper examines whether these cultural differences are expressed in complex multimodal media such as comics. We compared annotated panels across comics from six countries to examine how backgrounds convey contextual information of scenes in explicit or implicit ways. Compared to Western comics from the United States and Spain, East Asian comics from Japan and China expressed the context of scenes more implicitly. In addition, Nigerian comics moderately emulated American comics in background use, while Russian comics emulated Japanese manga, consistent with their visual styles. The six countries grouped together based on whether they employed more explicit strategies such as detailed, depicted backgrounds, or implicit strategies such as leaving the background empty. These cultural differences in background use can be attributed to both cognitive patterns of attention and comics’ graphic styles. Altogether, this study provides support for cultural differences in attention manifesting in visual narratives, and elucidates how spatial relationships are depicted in visual narratives across cultures.

Examining visual impact: predicting popularity and assessing social media visual strategies for NGOs
Authors: Koutromanou Elina , Sotirakou Catherine , Mourlas Constantinos
Published: October 2023

Purpose

This research aims to analyze the role of visuals posted on the social media of NGOs and to predict the popularity of a post based on the characteristics of the visual it contains.

Design/methodology/approach

Two social media platforms, namely Facebook and Instagram, were selected as the empirical study environments. Specifically, all visuals posted on 12 child-related Non-Government Organizations during the period of 2020–2021 (4,144 in total) were collected and subsequently subjected to automatic characterization using visual recognition and artificial intelligence tools. Machine learning algorithms were then employed to predict the popularity of a post solely based on the visuals it contains, as well as to identify the most significant features that serve as predictors for post popularity.

Findings

The Support Vector Classifier performed best with a prediction accuracy of 0.62 on Facebook and 0.81 on Instagram. For the explanation of the model, we used feature importance metrics and found that features like the presence of people and the emotions of joy and calmness are important for the prediction.

Practical implications

Companies and organizations serve a large part of their communication strategy through social media. Given that every advertiser would like to use their funds in the most efficient way, the ability to predict the performance of a post would be a very important tool.

Social implications

The methodology can be used in the non-profit sector, whereby knowing what visual will perform better they could promote their mission more effectively, increase public awareness, raise funds and reduce expenses on their communication strategy.

Originality/value

The novelty of this work regarding popularity prediction on social media lies in the fact that to make the prediction, it focused exclusively on the visual and its characteristics and achieved high accuracy scores in the case of Instagram. Additionally, it provided important information about visual characteristics and their importance in predicting popularity.
Behavioral capital: gaming and monetization in post-marxist perspective
Authors: Janoščík Václav
Published: October 2023

The most successful games today do not use a pay-for-product model, but involve complex and aggressive modes of monetizing their content (downloadable content, skins, in game currencies and markets, seasonal passes, etc.). While this has already been scrutinized, there are further consequences for games themselves and the economization of play. In my paper, I show how this strategy creates a conceptually novel situation, where playing can be considered to constitute reproductive labor-power and behavioral capital. In other words, playing here represents not only consumption but also the very production of such consumption, insofar as the main reason behind the massive success of these games is precisely their massive pool of players and data concerning their activity. Firstly, I analyse PUBG: Battlegrounds as an example of the most successful model of monetizing games and maintaining a large number of players and interaction. I focus both on the economic incentives as well as on the gameplay that is generated or tailored towards aggressive monetization. Later, I set a theoretical context for my analysis stemming from ludocapitalist discourse (itself combining Marx with poststructuralism) and the concept of surveillance capitalism. I conclude my text with a systematization and definition of my original concept of behavioral capital and an attempt to formulate art critique and usage of games as a form of cultural production exposing several examples from contemporary art.
