Enhancing EEG-based emotion recognition using PSD-Grouped Deep Echo State Network
Authors: Bouazizi Samar , Benmohamed Emna , Ltifi Hela
Published: October 2023

Emotions are a crucial aspect of daily life and play a vital role in shaping human inter-actions. The purpose of this paper is to introduce a novel approach to recognize human emotions through the use of electroencephalogram (EEG) signals. To recognize these signals for emotion prediction, we employ a paradigm of Reservoir Computing (RC), called Echo State Network (ESN). In our analysis, we focus on two specific classes of emotion recognition: H/L Arousal and H/L Valence. We suggest using the Deep ESN model in conjunction with the Welch Power Spectral Density (Wlech PSD) method for emotion classification and feature extraction. Furthermore, we feed the selected features to a grouped ESN for recognizing emotions. Our approach is validated on the well-known DEAP benchmark, which includes the EEG data from 32 participants. The proposed model achieved 89.32% accuracy for H/L Arousal and 91.21% accuracy for H/L Valence on the DEAP dataset. The obtained results demonstrate the effectiveness of our approach, which yields good performance compared to existing models of emotion analysis based on EEG.

Published: October 2023

Here we present an updated checklist of the genus Festuca in the Altai Mountains (AM). The study was carried out on the abundant herbarium material and considered the latest published phylogenetic analyses. Festuca was revised within the scope of the fine-leaved group (clade) with two sections, sect. Aulaxyper and sect. Festuca. Two species, namely F. richardsonii and F. lenensis, were previously misidentified and are not present in the AM. Festuca brevissima is a new record for the Russian part of the AM and for the flora of Mongolia. In total, our revision shows that 17 species of fine-leaved fescues are present in the area of AM. In this paper, we provide a key to species identification, as well as illustrations of plants, habits, leaves, spikelets, and glumes. Information on nomenclature types, synonymy, flowering period, chromosome numbers, habitats, and general distribution along with distribution maps of the particular species within the AM are included.

Authors: Tonkaz Gülsüm Yitik , Özyurt Gonca , Çakir Ali , Turan Bahadır , Utlu Bahadır , Özbay Ahmet Duhan
Published: October 2023

Purpose:

To investigate the changes in ocular optical coherence tomography (OCT) findings in the comorbidity of attention-deficit hyperactivity disorder (ADHD) and specific learning disorder (SLD).

Methods:

This study included 40 individuals diagnosed as having ADHD along with comorbid SLD, 40 individuals diagnosed as having only ADHD, and 40 individuals with no psychiatric disorders. OCT assessments were performed on eyes of the participants to obtain retinal nerve fiber layer (RNFL) thickness, ganglion cell complex (GCC) thickness, and macular thickness measurements.

Results:

In total, 240 eyes were evaluated. The right and left eyes were not significantly different in terms of RNFL, GCL, and macular thickness within groups (
P
> .05). RNFL thickness was measured and compared across four quadrants (superior, inferior, temporal, and nasal). Although these values were not significantly different between the groups (
P
> .05), RNFL was observed to be thinner in children with comorbid ADHD and SLD in all quadrants. Similarly, GCL and macular thickness measurements were also not different between the groups (
P
> .05).

Conclusions:

Considering that retinal nerve fibers can be seen as an extension of the brain in the embryologic context, the results showed that OCT findings alone are not sufficient to detect the changes in ADHD and SLD comorbidity. The authors suggest that OCT is more useful in the etiology and follow-up of neurodegenerative diseases rather than neurodevelopmental disorders.

More complex dynamics in a discrete prey-predator model with the Allee effect in prey
Authors: Ruan Mianjian , Li Xianyi , Sun Bo
Published: October 2023

In this paper, we revisit a discrete prey-predator model with the Allee effect in prey to find its more complex dynamical properties. After pointing out and correcting those known errors for the local stability of the unique positive fixed point $ E_*, $ unlike previous studies in which the author only considered the codim 1 Neimark-Sacker bifurcation at the fixed point $ E_*, $ we focus on deriving many new bifurcation results, namely, the codim 1 transcritical bifurcation at the trivial fixed point $ E_1, $ the codim 1 transcritical and period-doubling bifurcations at the boundary fixed point $ E_2, $ the codim 1 period-doubling bifurcation and the codim 2 1:2 resonance bifurcation at the positive fixed point $ E_* $. The obtained theoretical results are also further illustrated via numerical simulations. Some new dynamics are numerically found. Our new results clearly demonstrate that the occurrence of 1:2 resonance bifurcation confirms that this system is strongly unstable, indicating that the predator and the prey will increase rapidly and breakout suddenly.

Influence of Natural Gas Pipeline Right-of-Ways on Eastern Red-Backed Salamander Occurrence in the Northern Appalachians
Authors: Brown Donald J. , Knopka Samuel C. , Grushecky Shawn T. , Owen Sheldon F. , Edwards John W.
Published: October 2023

Road and pipeline infrastructure development for natural gas extraction often results in forest fragmentation, which could negatively influence habitat quality for many amphibian species. We investigated occurrence dynamics of the eastern red-backed salamander Plethodon cinereus in relation to natural gas pipeline rights-of-way (ROWs) and forest structure characteristics in northern Pennsylvania, USA. We sampled 80 sites across two study areas by using coverboards, with each site containing sampling plots at the center of the ROW, the edge of the ROW, and 10 m and 30 m into the adjacent forest. We assessed the influence of ROW age, ROW width, distance from ROW, and five forest structure characteristics on plot occupancy probability. Eastern red-backed salamander occupancy probability decreased with ROW age and increased with distance from ROW. Our results indicate that eastern red-backed salamanders are negatively influenced by forest fragmentation for natural gas ROWs. Moreover, responses were time dependent, with occupancy probability declining with ROW age. Due to low detections, we were unable to analyze data for the other amphibians and reptiles encountered during the study. Our capture data indicate that ROWs could improve habitat quality for some snake species, but additional research is needed to better understand the influence of ROWs on reptile species. To reduce future forest fragmentation and impacts on eastern red-backed salamander populations, managers could consider placing pipelines along existing linear clearings and enhancing the habitat quality of ROWs for salamanders.
Sur le seuil de la prison de Laon
Authors: Génard Elsa
Published: October 2023

À partir d’un corpus de 605 individus écroués entre 1912 et 1939 dans la maison de correction de Laon, cet article propose conjointement une sociographie des condamnés et une analyse de leurs modalités d’incarcération. Après avoir montré que les prisonniers et les prisonnières appartiennent aux classes populaires défavorisées de l’Aisne, l’article s’attache à décrire les clivages qui structurent la population pénitentiaire laonnoise. À un groupe particulièrement désaffilié s’oppose un ensemble d’individus pouvant témoigner de gages d’insertion sociale. Ces distinctions socio-pénales permettent, dans un second temps, d’éclairer les différentes voies qui mènent aux portes de la prison de Laon. Quatre types d’entrée sont distingués, en fonction de la vitesse d’exécution des décisions judiciaires et de la présence ou non d’un agent des forces de l’ordre. La détention préventive, la coercition rapide, la coercition retardée et la constitution volontaire dessinent une gamme élargie de l’expérience du pouvoir de l’État dans la France du premier XXe siècle. Loin de se réduire à l’application mécanique d’une procédure, l’incarcération apparaît comme une pratique sociale qui n’offre pas les mêmes marges de manœuvre à tous les individus.
From Historical Social Science to the Historical Study of Crime
Authors: Catello Roberto
Published: October 2023

This article develops a sui generis account of the genesis of the historical study of crime that resists the temptation to attribute the beginning of the social history of crime to the emergence of the “History from Below” movement of the 1970s. Written from the point of view of a historical criminologist, the article argues that studying crime historically requires giving equal weight to the “historical study of crime” and to the “criminological study of the past”. By arguing that the study of crime in historical perspective is best understood as a particular instantiation of what Immanuel Wallerstein called “historical social science”, the article develops a characterization of the historical study of crime that moves beyond its conventional representation as a history specialization.

Authors: Zakharova Marina A. , Karpacheva Irina A. , Mezinov Vladimir N. , Mironova Elina L.
Published: October 2023

The development of the education system is closely connected with scientific progress, the country's economic growth, social evolution, and individuals' intellectual capital. Teachers play the most critical role in the modernization of educational processes in Russia, the authors argue. The professional socialization of future teachers contributes to their successful inclusion in labor markets, strengthens hidden resources, forms an original style of thinking, and helps to assimilate ethical standards. The essence of the concept of “professional socialization of the future teacher” is discussed in the chapter. Furthermore, the authors focus on critical aspects within the process of professional socialization; and the pedagogical conditions for the success of its implementation are analyzed and discussed. The research demonstrates that the modernization of Russian society has significantly changed the nature of the socio-cultural influence on the personality of students. The inclusion of students in various types of interactive dialogue interactions creates real prerequisites for developing personal and professional qualities, raising professional maturity of an individual, and high contribution to the assimilation of social values. The authors conclude that the professional socialization of students mastering the profession of a teacher goes through two main stages in their development, namely adaptation and professional identification.
The Essence of Pedagogical Interaction in the Educational Process of Higher Education
Authors: Nebrodovskaya-Mazur Elena Yu. , Matveeva Inna P.
Published: October 2023

The chapter discusses the essence of pedagogical interactions as a complex subject-to-subject, socio-psycho-pedagogical concept, reflecting direct or indirect interconnected and mutually conditioned actions that are determined by the needs of subjects participating in the educational process in post-secondary school for enriching knowledge and experience, value and information exchange, carrying out joint duties and activities. Such actions are reflected upon by the actors of the educational process and directed towards facilitation and accomplishment of professional tasks. The chapter outlines the methodological basis for the emergence of pedagogical interaction as an independent category. The classification of scientific approaches to the definition of the essence of the concept of “pedagogical interaction” is given. The essence of “pedagogical interaction,” seen through the fundamental principles of education, is analyzed and discussed. The value-reflexive type of interaction in post-secondary school is analyzed and determined to be the most effective in targeting the humanistic nature of learning. Both the essence and critical features of the value-reflexive accompaniment of professional training allowed it to reveal its structural content, including cognitive, reflexive-active, and personality-value components. The research emphasizes that the orientation in social interaction to reflect the value content involves many features: (1) the definition of main vectors of value content, (2) the most fulsome components of social interaction in the field of professional activity (values, opportunities, morality, rules, methods, and means), and (3) the formation of a harmonious and value-based attitude to the nature of interaction within the educational team through the reflection of personal experience. Based on the theoretical analysis and empirical research, the authors argue that the reflexive value support of professional training is a solution to some issues in education.

Published: October 2023

The chapter discusses the problems of training IT specialists in universities. The authors argue in favor of improving this training, which requires a special attitude both to the content and technical support, as well as to teaching methods and forms. Among the most demanding issues are the difference between the scientific field and the scientific content of academic disciplines, the inevitability of the emergence of new academic disciplines on an interdisciplinary basis, the need to attract specialized IT specialists. An approach to training IT specialists through interdisciplinary forms and teaching methods is proposed and discussed by the authors. This approach is based on the creation of training courses at the junction of several disciplines. An example of applying an interdisciplinary approach to the preparation of a bachelor's in computer science and computer engineering is discussed.

In an effort to improve HLA-“humanized” mouse models for type 1 diabetes (T1D) therapy development, we previously generated directly in the NOD strain CRISPR/Cas9-mediated deletions of various combinations of murine MHC genes. These new models improved upon previously available platforms by retaining β2-microglobulin functionality in FcRn and nonclassical MHC class I formation. As proof of concept, we generated H2-Db/H2-Kd double knockout NOD mice expressing human HLA-A*0201 or HLA-B*3906 class I variants that both supported autoreactive diabetogenic CD8+ T cell responses. In this follow-up work, we now describe the creation of 10 new NOD-based mouse models expressing various combinations of HLA genes with and without chimeric transgenic human TCRs reactive to proinsulin/insulin. The new TCR-transgenic models develop differing levels of insulitis mediated by HLA-DQ8–restricted insulin-reactive T cells. Additionally, these transgenic T cells can transfer insulitis to newly developed NSG mice lacking classical murine MHC molecules, but expressing HLA-DQ8. These new models can be used to test potential therapeutics for a possible capacity to reduce islet infiltration or change the phenotype of T cells expressing type 1 diabetes patient-derived β cell autoantigen-specific TCRs.
From Snow’s map of cholera transmission to dynamic catchment boundary delineation: current front lines in spatial analysis
Authors: Kiani Behzad , Lau Colleen , Bergquist Robert
Published: October 2023

The history of mapping infectious diseases dates back to the 19th century when Dr John Snow utilised spatial analysis to pinpoint the source of the 1854 cholera outbreak in London, a ground-breaking work that laid the foundation for modern epidemiology and disease mapping (Newsom, 2006). As technology advanced, so did mapping techniques. In the late 20th century, geographic information systems (GIS) revolutionized disease mapping by enabling researchers to overlay diverse datasets to visualise and analyse complex spatial patterns (Bergquist & Manda 2019; Hashtarkhani et al., 2021). The COVID-19 pandemic showed that disease mapping is particularly valuable for optimising prevention and control strategies of infectious diseases by prioritising geographical targeting interventions and containment strategies (Mohammadi et al., 2021). Today, with the aid of highresolution satellite imagery, geo-referenced electronic data collection systems, real-time data feeds, and sophisticated modelling algorithms, disease mapping has become a feasible and accessible tool for public health officials in tracking, managing, and mitigating the spread of infectious diseases at global, regional and local scales (Hay et al., 2013).

Minimally invasive approach of paediatric neuroblastoma with thoracic vascular encasement
Authors: Pio Luca , Zaghloul Tarek , Abdelhafeez Abdelhafeez Hafeez
Published: October 2023

Neuroblastoma (NB) is the most frequent paediatric extracranial solid tumour. The surgical management of these tumours in newborns changed recently, performing resections in cases with tumour size increase after birth. Minimally invasive procedures were mostly reported in cases without pre-operative image-defined risk factors (IDRFs), defined by vascular and organ involvement. Thoracoscopic resection represents a minority of the overall surgical procedures for neuroblastic tumour management, as the posterior mediastinum is one of the least frequent locations of NB. A thoracoscopic resection was performed on a 22-month-old child with a NB encasing the aorta and a 6-month-old child with the encasement of the left subclavian and vertebral artery. A step-by-step minimally invasive procedure was described, highlighting anatomical landmarks and dissection techniques. The described technique was performed in 130 min. Thoracoscopic resection provided a macroscopic resection without surgical complications and patient was discharged on the 3rd post-operative day. The study shows a feasible and safe thoracoscopic approach for paediatric thoracic NB with IDRFs.

Compensation Assessment for Personal Injury Owing to Extra-Contractual Liability: Case Study on Selected Courts
Authors: Meaza Haddis  , Nigussie Afesha
Published: October 2023

Assessment of compensation for personal injury is an intricate part of the law of extra-contractual liability (torts) since such kind of injury results in loss of a job, part of a body, total permanent disability or death. As personal injury may involve irreparable harm, it challenges courts in quantifying reasonable expenses a victim incurs and determining the amount of disability indemnity. By using decisions of the SNNP and Sidama regional courts together with selected Federal Cassation decisions, this article aims to explore practices of compensation assessment for personal injury. The Civil Code, which applies in federal and state courts, requires assessment of damage and award compensation based on a rule of equivalency. Given the generality of this, courts are facing difficulties in making compensation assessments for extra-contractual wrongs that result in personal injury. The problems are related to quantifying reasonable expenses for treatment, determining the amount of disability indemnity, or deciding which kinds of pecuniary losses are included in and excluded from compensation assessment. These problems have caused arbitrary decisions of the courts for personal injury. Variation also exists among court decisions at various levels in determining the extent of harm a claimant sustains and its corresponding compensation. Lack of detailed provisions contributes to such variation, and this calls for legal reform.
Regulation of Group of Companies in Ethiopia: A Comparative Overview
Authors: Mesfin Beyene
Published: October 2023

Companies that are organized in a group aim at leveraging the market share, mitigate liability or facilitate long-term management efficiency. The reasons that make group establishment attractive for the parent company can be a basis for concern to other stakeholders, mainly, minority shareholders and creditors of the subsidiary company. The strict application of separate existence of a company and directors’ fiduciary duties towards their companies –applicable in cases of single entity companies– may be difficult in the case of group companies. States, therefore, devise regulatory mechanisms to protect the subsidiary company and its minority shareholders and creditors while at the same time protecting corporate freedom and entrepreneurial reality. Ethiopia has introduced regulatory rules regarding group company (Parent-Subsidiary Company). The objective of this article is to discuss the nature and regulation of Group Company as specified under the new commercial code and in comparison, with other countries’ laws. The article argues that the rules stipulated are not designed to adequately protect the interests of the subsidiary and its stakeholders. It also argues that the liberal interpretation of the provisions governing group companies to include the application of rules governing single company can contribute to potential protection rules missing under the sections in the group company.

Published: October 2023

IntroductionThe learning environment is defined as an environment where teaching is taking place, as perceived by both students and teachers. A conducive learning environment is critical for successful curriculum implementation, which also affects students’ academic performance. There have been initiatives introduced to improve the learning environment at Kamuzu University of Health Sciences (KUHeS). The purpose of this study was to ascertain physiotherapy final year students’ perceptions of their learning environment at KUHeS in Malawi.MethodologyThis study was conducted at KUHeS among final-year physiotherapy students. A retrospective, quantitative cross-sectional design was used. The study utilised secondary data on education environment which had already been collected using Dundee Ready Education Environment Measure (DREEM) forms. There were 26 completed DREEM forms for 2019/2020 academic year. Demographic data were captured. Mean and standard deviation were used to analyse the DREEM scores. Inferential analysis was conducted with p-value set at ≤ 0.05. Results The total DREEM mean score was 120/200 which represented a positive perception of students learning environment. Students’ academic self-perception scored the highest (69.13%), followed by students’ perception of learning (61.94%), students’ social self-perception (59.46%), students’ perception of atmosphere (56.25), and students’ perception of teachers (55.50%). Married students had negative perceptions (p-value = 0.05) of their teachers and students with previous college experience had positive perceptions of their academic performance (p-value = 0.02). Many statements under items of perception of teachers (mean score = 24) and social self-perceptions (mean score = 16) were considered negatively. ConclusionStudents in their final year of physiotherapy had positive perceptions of their learning environment. However, students’ perceptions of their teachers and social life were low. The learning environment had a significant impact on married students and those who had no prior experience with college life. Faculty development initiatives should aim to improve these critical areas.
Identifying the optimal phenological period for discriminating subtropical fruit tree crops using multi-temporal Sentinel-2 data and Google Earth Engine
Authors: Chabalala Yingisani , Adam Elhadi , Ali Khalid Adem
Published: October 2023

The accurate and appropriate monitoring of the spatial distribution of fruit tree crops is crucial for crop management and yield forecasting. Owing to both inter- and intra-farm fragmentation and overlapping phenological cycles, the classification of fruit tree crops in subtropical agriculture using single-date images is challenging. Therefore, this research aimed to identify the optimal temporal window in which the crucial phenological stages can be used to classify fruit tree crops in Levubu, Limpopo province, using a random forest (RF) classifier. Phenological metrics were extracted from 12-month Multispectral Instrument (MSI) images from Sentinel-2 (S2). The RF classification algorithm attained an overall accuracy of 84.89% and a kappa coefficient of 83%. The user accuracy ranged from 62  to 100%, while the producer accuracy ranged from 60 to 100%. An analysis of variance was used to assess whether the overall accuracies among the S2 monthly composites were statistically significant. The results showed distinct spectral differences between fruit trees. In April, there were differences observed during the harvesting and senescence of the mango and macadamia nut crops. In May, there were differences observed during the senescence of the macadamia nut, mango, and guava crops. In June and July, there were distinct spectral differences during the peak flowering stage of the avocado, macadamia nut, and mango crops, as well as in the fruiting stage of the banana crops. Followed by the red-edge bands, the shortwave infrared bands were significant in differentiating between the respective fruit tree crops. The results of this research provide evidence-based information that can assist farm managers and horticulturists in making informed decisions. This is critical in achieving effective agricultural management and in ensuring the sustainability of local horticultural systems.

Published: October 2023

Cervical-Vaginal Dysbiosis refers to an imbalance or disruption in the microbial communities inhabiting the cervix and vaginal tract, leading to an altered composition of microorganisms, often accompanied by a decline in overall vaginal health. This phenomenon contrasts with the notion of a balanced and stable vaginal microbiome, which is characterized by the predominance of Lactobacillus species, known for their protective properties against infections and maintenance of a low pH environment This study evaluates the potential of cervical-vaginal dysbiosis among patients with clinical presentation of cervical vaginal infection in Private Medical Laboratories with limited diagnostics resources and specialization. It addresses the need for cytological investigation in addition to microbiological techniques. Clinical queries of cervical-vaginal infections of patients in twelve selected private medical laboratories in Abakaliki Ebonyi state Nigeria was studied. A total number of 38 patients who met the eligibility criteria were recruited into this study. Cervical- vaginal smear was collected from each subject, samples were fixed, and stained using Papanicolaou and Diff-Quick staining method. Out of these 38 smear samples, 17 (44.7%) had normal cytological features with no microbial features observed. Out of the remaining 21 smear samples, Trichomonas vaginalis occurred 9 times(42.9%), followed by fungi occurring 6 times (28.5%), Human papillomavirus occurring 4 times (19.1%) and Actinomyces occurring 2 times(9.5%). Notable cytological features were revealed, these included squamous intraepithelial lesions characterized by parabasal cells showing perinuclear halo, hyperchromatic nuclei, and slight nuclei polymorphism. Inflammatory lesions were also observed, characterized by the conspicuous number of superficial cells, inflammatory background, red blood cells, and infiltrating polymorphs. This study has highlighted the need to adopt a more proactive approach by evaluating the microbial profile of the cervical smear, which can be a risk factor for cervical malignancy; it has also buttressed the need to retrain and incorporate cytology services in private laboratories.

This study aims to increase public knowledge about the processing of guava leaves as herbal medicine to treat diarrhea. Prior to counseling and training, the results of the pretest showed that most of the participants (70.5%) had known the utilization and processing of guava leaves as herbal medicine. After attending the training, participants were given a post-test questionnaire to measure the increase in their knowledge.The results showed that there was a significant increase in the participants' knowledge after attending the training. The knowledge percentage increased from 70.5% to 89.0%, representing an increase of 18.5%. This training provides information on how to process guava leaves into herbal medicines that are effective in treating diarrhea.Some of the processing methods taught in the training include making guava leaf tea, guava leaf extract, and decoction of guava leaves. Participants were also given knowledge about the active ingredients in guava leaves, such as quercetin, which has an anti-diarrhea effect.This study showed that the counseling and training program was effective in increasing participants' knowledge about processing guava leaves as a herbal medicine to treat diarrhea. With the knowledge gained, it is hoped that the community can properly process guava leaves and use them effectively in maintaining health and treating diarrhea with simple medication. This program also empowers garden plants in the environment around the village as an easily accessible source of herbal medicines.

This research aims to analyze the influence of Islamic financial literacy, capital requirements, ratios, and convenience on the interest of micro, small, and medium enterprises (MSMEs) to become Islamic bank financing customers. This research uses a descriptive quantitative approach with an analytical method such as multiple linear regression. The population of this research is all MSME actors in East Java. The research sample was obtained from 63 MSMEs in East Java using the Roscoe approach. The data source uses primary data as a questionnaire and is analyzed using multiple linear regression. The research results show that Islamic financial literacy, capital requirements, nisba, and convenience significantly influence the interest of MSMEs to become Islamic bank financing customers. Partially, only the nisba positively and significantly affects the interest of MSMEs to become Islamic bank financing customers. Islamic financial literacy, capital requirements, and convenience do not influence the interest of MSMEs to become Islamic bank financing customers. This research can be used as a complement to existing theories. It can be used as a reference for Islamic banks and the government in developing strategies to attract MSMEs to become Islamic bank financing customers.
Educación y migración. Etnografía-narrativa de la práctica docente en contexto migratorio en el Estado de México
Authors: Velasco Orozco Juan Jesús
Published: October 2023

El libro da cuenta de los resultados de una investigación sobre la práctica docente en contexto de migración, realizada desde los propios sujetos mediante la narrativa de una de sus experiencias críticas. Para ello, el primer capítulo presenta lo que se entiente por práctica docente, distinquiendo sujeto y objeto. En el siguiente capítulo se ubica conceptualmente el fenómeno migratorio y, posteriormente, se presentan las narrativas de la experiencia docente. El capítulo tercero muestra el resultado del análisis de las narrativas en función del tipo de migración, la condición del alumnado y la práctica docente desplegada. Finalmente, el cuarto capítulo que continúa con el análisis pero en esta ocasión sobre el sentir y hacer docente en la configuración de la práctica docente situada.

Building delayed dynamical models to describe the inherent laws of different chemical matters has become a hot theme in recent years. In this current study, we set up a new fractional-order delayed turbidostat model. By using laplace transform, we obtain the characteristic equation of established fractional-order delayed turbidostat model. By selecting the delay as bifurcation parameter and exploring the roots of the corresponding characteristic equation of the involved fractional-order delayed turbidostat model, a novel delay-dependent condition on stability and Hopf bifurcation is acquired. Taking advantage of a novel extended hybrid controller, the stability region and the time of Hopf bifurcation of the established fractional-order delayed turbidostat model are successfully controlled. The role of delay in stabilizing system and controlling Hopf bifurcation is revealed. Matlab experiments are carried out to check the rationality of the acquired key outcomes in this article. The acquired outcomes of this study are completely new and own great theoretical value in dominating concentrations of various chemical matters.
Neo-adjuvant PIPAC and Systemic Chemotherapy in Management of Synchronous Peritoneal Metastasis From Gastric Cancer
Authors: J Spiliotis
Published: October 2023

Introduction: Polycystic Ovarian Disorder (PCOD) is a prevalent endocrine illness in women of reproductive age. It has hormonal abnormalities, irregular menstrual cycles and tiny ovarian cysts. Lifestyle and food affect PCOD development and maintenance, coupled with Peritoneal metastasis from gastric cancer remains a major problem.

The aim of our study is a retrospective analysis in two different groups with used PIPAC as neo-adjuvant management of synchronous peritoneal metastasis.

Group A: 42 patients received as neo-adjuvant treatment 2 cycles of PIPAC (Doxorubicin 3 mgr/m2, cisplatin 10 mgr/m2) and 6 cycles of neo-adjuvant systemic chemotherapy with FLOT and we performed CRS+HIPEC (with cisplatin 80 mgr/m2, mitomycin 35 mgr/m2) for 90 min and 6 cycles of adjuvant systemic chemotherapy with FLOT.

Group B: 26 patients received 4 cycles of neo-adjuvant systemic chemotherapy with FLOT, we performed CRS+HIPEC as Group A and 4 cycles of systemic chemotherapy with FLOT.

For patients of Group A, the Median survival time is 46months.Group B patients had a median OS of 36 months.

For patients of Group A, the Median Disease Time (DFS) was 37 months. Group B patients had a median DFS of 30 months. For each degree increase in the PCI pre score and for the same treatment group, the PCI posr score increases by 0.573 degrees. Group 2, for the same PCIpre score, have a 163% higher PCI posr score. On patients with singet ring cell adenocarcinoma there is a statistical significance difference in OS for PIPAC group. Patients of group A had a median OS of 26 months. For patients of group B, the median OS was 14 months. Morbidity and mortality in both groups are 53,4% and 4,7% for Group A and 44,5% and 5,5% for Group B respectively. The neo-adjuvant PIPAC with systemic chemotherapy might be a promising approach for patients with peritoneal metastasis from gastric cancer. PIPAC is a safe and well tolerated procedure.
