In the wake of the COVID-19 pandemic, the novel class of mRNA vaccines has been granted first-time approval for active immunization against SARS-CoV-2 alongside the already established viral vector-based vaccines. In this prospective single-center study, we set out to determine the vaccine-induced humoral immune response in a population of 1512 health care employees after the second and third vaccination, respectively. Anti-SARS-CoV-2 receptor-binding domain (RBD) and nucleocapsid antigen antibody concentrations were assessed using commercially available immunoassays. We could show that, in particular, young study subjects aged below 30 years, as well as those with a prior SARS-CoV-2 infection, developed significantly higher antibody concentrations. Our data further suggest that being in physically close contact with formerly SARS-CoV-2-positive people positively affects the post-vaccination response. Surprisingly, study subjects with a BMI > 30 produced the highest anti-S-RBD Ig antibody levels if they had recently received their third vaccination. Also, heterologous dual vaccine regimens consisting of a BNT162b2 and ChAdOx1 n-CoV-19, a homologous triple combination of BNT162b2, and an application of mRNA-1273 as the third vaccine, were most efficient at eliciting a humoral immune response. Our study substantiates existing evidence, but beyond that, scrutinizes the impact of vaccine agents and their respective combinations, as well as different time intervals on humoral immunogenicity.
Modelling Climate Change and Water Quality in the Canadian Prairies Using Loosely Coupled WASP and CE-QUAL-W2
Authors: Terry Julie , Lindenschmidt Karl-Erich
Published: September 2023

The prairie waterbodies face a future of warming temperatures and growing water demands. There are increasing concerns about how water quality will be affected. Water quality models are an effective tool for examining scenarios of future conditions that cannot be measured directly. This study combined WASP and CE-QUAL-W2 to investigate the potential impacts of changing flow management and climate change in the Canadian Prairies. The two models were loosely coupled to simulate a strategically managed river-reservoir network. Climate data from the Coupled Model Intercomparison Project Phase 6 (CMIP6) model ensemble were used to create future climate scenarios. Interbasin water transfers were then simulated through the coupled models to determine if any negative impacts from climate change on water quality could be offset through flow management. Climate change impacts in the river stretch were minimised due to the rapid flow travel time along the channel. The interbasin water transfers had a greater influence on water quality concentrations in the river. This result was limited by the uncertain hydro-climatic future of the contributing watershed. Climate change impacts in the downstream reservoir were far more apparent. Evaporative losses increased approximately 150% from the base model by the 2080–2100 period. Chlorophyll-a concentrations increased an average of 53% in this same period based on monthly mean percentage change. Reservoir water quality was improved after adding the interbasin water transfers. Results indicated that flow management would have a positive impact on water quality in the reservoir in the face of future climate change.

Published: September 2023

Over the past decade, there have been qualitative changes in the field of hydrogen energy and technologies related to it. The concept of hydrogen systems, which originated in the late 70s of the last century, has now grown into a dynamically developing scientific and technical direction, included in the development program not only of individual countries, but also of the global energy sector as a whole. Russia can also make a great contribution to the creation of the global hydrogen infrastructure in the future. In the future, our country can become one of the leading suppliers of "green" hydrogen to the world market, which will make the Russian economy more competitive. However, it should be noted that until now, in many national concepts for the development of hydrogen energy, as well as at the level of individual companies, there is a lack of a systematic approach and balanced strategic recommendations, which often hinders the development of this area of energy and related industries.

Authors:   LLC ", Panchenko K.E. ,   Kvatromatik"
Published: September 2023

In the modern understanding, automation of business processes is the use of computers, networks, high-tech manipulators, equipment and systems based on artificial intelligence and machine vision in an enterprise. First of all, automation of business processes is the simplification of the work of employees of the enterprise, the replacement of manual or human labor with machine labor, in order to improve and improve the quality indicators of manufactured products. In the age of digitalization, there are still quite a lot of processes in companies and industries that remain non-automated. Quite a lot of processes depend on a person, there are no objective means of continuous accounting, measurement and quality control of products. How to automate industries in which manual quality control of manufactured products was until today the most common way of working, gradually improving processes and releasing even greater production potential, and what economic effect can be obtained, is presented in this material.
An International Study of Democracy and Perceived Wellbeing
Authors: Mungar Alexandria , Cramer Kenneth
Published: September 2023

The present study evaluated 85,000 respondents (from almost 60 nations) in the World Values Survey (Wave -6) and the link between perceived democracy and income brackets, plus their current state of health, happiness, and satisfaction with both life and finances. Mean scores for each nation then informed a secondary analysis by including GDP/capita. Results showed that income brackets were correlated to health and financial satisfaction while GDP/capita correlated with financial satisfaction among both high and lowincome levels. Multiple regression analyses confirmed the hypotheses: (a) that higher perceived democracy was positively related to wellbeing and health; and (b) that the relation between perceived democracy and wellbeing was moderated by income, with stronger correlations observed in both low-income and highincome (but not middle-income) nations. We conclude that democratic nations offer more personal and political freedoms, while securing better wages, income, and health care opportunities for their citizens. Future research is discussed.

Authors: Arslan Hilal , Toltar Ali
Published: September 2023

In this study, spatiotemporal relationship between PM2.5 and PM10 concentrations and meteorological parameters were investigated for Silivri and Umraniye districts in Istanbul for 2014-2020. For this purpose, hourly PM2.5 and PM10 concentrations values of two air quality monitoring stations and meteorological data (wind speed, wind direction, relative humidity, total precipitation, minimum and maximum temperature) were examined. In all seasons, while PM concentrations were lowest at 06:00 local time (LT), PM2.5 and PM10 have peak values around 09:00 and 19:00 LT both in Silivri and Umraniye mainly due to anthropogenic activities such as vehicle exhaust emissions. In daily perspective, highest PM values were observed on Sundays in winter at Silivri. On the other side, peak PM values are shown on Fridays at Umraniye. It was found that local emission sources during low wind speeds cause the highest PM2.5 concentrations during winter months and southerly winds exceeding 8 m/s increase the PM10 levels at Silivri and Umraniye. The statistical analysis showed that PM2.5 and PM10 concentrations at Silivri were negatively correlated with wind speed with correlation coefficients of -0.56 (winter), -0.47 (autumn), respectively. Wind speed is negatively associated with PM2.5 (r=-0.48) and PM10 (r=-0.38) in winter season at Umraniye. In addition to this, relative humidity showed negative relationship with PM10 (r=-0.43) in spring at Silivri, while a positive correlation was found between PM10 (r=0.40) and PM2.5 (r=0.38) measured in the summer season and the maximum temperature. In addition to the anthropogenic factors (e.g. urbanization, transportation, and industrialization) that decrease air quality of Istanbul, local meteorological variables and atmospheric transport of pollution are observed to be the other factors that contribute to air pollution.

Identification of issues and Future Improvement Strategies for Emergency Welfare Support Act for Ex-prisoners
Authors:   The Correction Welfare Society of Korea, Kim Jeonghyeon , Cho Hee-won
Published: September 2023

This study proposes alternatives for improving the delivery system of emergency welfare support for ex-prisoners, particularly suggesting ways to integrate the emergency support system with the rehabilitative welfare system. The aim is to propose alternatives for ex-prisoners' independence and recidivism prevention. Based on existing research data, this study explores the current status, trends, and operational issues of emergency welfare support. It identifies issues and key points of contention in emergency welfare support for ex-prisoners. Drawing from this analysis, the study aims to present policy alternatives and development strategies to enhance the effectiveness and efficiency of the emergency welfare support system for ex-prisoners.
The study results reveal a continuous and sharp increase in the number of cases and the amount of support provided through the emergency welfare support. Among these, the number of support cases for ex-prisoners has drastically risen from 1,135 cases in 2014 to 49,513 cases in 2020. Given the nature of the emergency support system, the entire process, from application-related investigations to decisions, disbursement management, and post-assessment, is carried out by dedicated personnel in a one-stop delivery system. This has led to burdens on frontline local government agencies due to heavy workloads and stresses from public complaints. Notably, many challenges have been raised concerning support for ex-prisoners.
Consequently, this study aims to discuss integrated community services by proposing a delivery system and case management system linkage and improvement approach with the Korea Rehabilitation Agency responsible for ex-prisoners' recidivism prevention and social integration.
The Transition Between Rural and Urban Spaces in Fragile Peri-Urban Fringes: Water as a Primary Design Tool
Authors:   Politecnico di Milano, Dondi Lvinia
Published: September 2023

The focus is on the peri-urban landscape, placed between suburban settlements and the surrounding countryside. It is an “uncertain” area, unable to have crucial urban relationships and convincing rural and agricultural fabric. Different expressions of fragility, both physical and social, coagulate in these places: the reason why they represented a significant object of study for several decades, becoming symbols of problematic urban models. Among the possible regeneration processes, the one that starts from a rural, rather than urban, perspective seems to be the most interesting. Today, what appears essential is considering the peri-urban countryside areas, not as a possibility for the urban fabric to expand, but as the necessary open spaces that complete the suburban fringes’ layout. Actively involving rural areas contributes to a more effective transition between countryside and urban elements and improves a general reinforcement of the open spaces system, thus conceiving as the settlement backbone. The importance of inhabiting countryside as leasure spaces for the citizens, beyond agricultural production settings, became more urgent during pandemic times, in which wide open spaces became the safest areas. Therefore, to imagine a multifunctional countryside to inhabit, one of the crucial design tools to work with is the water. Streams innervating the countryside can represent pivotal devices to rethink transitional open spaces in layout and uses between rural and urban practices. Simultaneously, working with streams allows counteracting or preventing possible water imbalances investing and damaging urban areas due to climate change effects and inadequate ways to anthropize the territories. The more dilatated fabric of the peri-urban landscape allows considering water and its ecological connections as a primary design tool.
Mobility and Migration as Constituting Elements of Urban Society: Migration as a Gendered Process and How to Challenge Digital Universalism
Authors:   ETH Zurich, Charitonidou Marianna
Published: September 2023

The paper aims to present an ensemble of new theoretical frameworks that would allow historiographies of architecture and urban design to take into consideration the question of migration as a gendered process. Unauthorised immigration has emerged as a generalised fact in all Western economies in the post-Second World War era. In such a context, mobility and migration are constituting elements of urban society. Taking as a starting point the fact that domesticity is a construction of the nineteenth century, the main objective of this paper is to shed light on how migration challenges the concepts of user, domesticity and citizenship. Migrant incorporation triggers processes of place-making which open up new social and conceptual spaces in the city. Over the last four decades, there is a changing paradigm in migration studies. This shift is related to the fact that migration studies are gradually paying more and more attention to the gender composition of the migration streams. This trend of studying conjointly gender and migration phenomena becomes more and more dominant. Special attention is paid to methods of gender and migration scholarship that draw on social sci¬ence approaches, treating gender as an institutional part of migration studies and establishing legitimacy for gender in migration studies. The paper reflects upon the implications of establishing methods based on the endeavour to merge migration studies, urban studies and gender studies for the perception of the concepts of placemaking, displacement and domesticity, on the one hand, and for how the mobility from city to city is understood within the contemporary transnational context, on the other hand. Particular emphasis is placed on the relationship between the migration processes and social sustainability. Additionally, the paper examines the role of new media technologies in rethinking the dynamics of migration. It also analyses how we could shape strategies of using urban scale digital twins and big data for decision-making in urban planning that are able to challenge digital universalism.

Increasing man-made and natural disasters compel architecture educators to revisit how students as future practitioners can best address the challenges of housing a growing number of forcibly displaced people. The complexities of domestic and global contexts are difficult to generalize. Migrant demo¬graphics and their economic and political circumstances vary widely, as do time lines for resettlement and the possibility of eventual repatriation. The broad classifications of displaced people (e.g., refugee, asylum seeker, internally displaced people) do not illuminate distinct personal conditions. Through background research, interviews with experts in the field, and experimental teaching, we consider how forced migration trends challenge established pedagogical approaches and existing models of architectural practice. We evaluate the role of architects when designing for uncertain and turbulent contexts in which empathic design is essential. The diversity of situations makes it impossible to determine a fixed playbook to follow. We conclude that rather than prescribing a definitive professional role or predicting a standard set of responsibilities, we can address these questions by formulating critical thinking exercises and identifying key considerations as they relate to distinct circumstances. We must look ahead to a time when our students will need to work out solutions and strategies on their own and provide attitudes and skills for sensitively addressing dynamic crisis situations.
Designing for Change: Exploring Open Design Strategies in Architectural Design

While sustainability is increasingly considered a core topic in architectural design curricula, the dominant focus is still on technical and environmental aspects. Yet how the built environment becomes part of people’s (future) everyday living matters greatly. Its ability to meaningfully change along with uses, users and contexts is an important measure of sustainability. Taking into account use-related aspects, however, requires finding ways to deal with the uncertainty and complexity that this invites into design processes. Searching for approaches that acknowledge this uncer¬tainty and complexity in how we teach and study design, we explored the value of weaving an open design approach into architectural education. We looked at attempts in industrial design engineering, specifically open-ended design and open script design. These strategies aim to bring into view the dynamic with which products become part of real environments that are ever-changing and unpredictable. We adopted an action research approach: in a compulsory course on actual topics we involved master students in architectural engineering as researchers to explore these strategies’ value and applicability in architectural design. The course module was offered twice. From the first iteration, reported on elsewhere, we learned that open design formalizes a mode of thinking that is latently present to students in their education and design work and connects to sustainability. In this paper we report on the second iteration and further explore this connection. Analysis of students’ work shows that they adopt a relational perspective, viewing sustainability as a quality of the relations between the built environment and its users. And that on a practical level, working with these strategies incites normative and future thinking in students’ spatial analyses—core competencies in sustainability literacy. The major challenge we see towards the future lies in moving on from applying strategies to developing a sustainability mindset.
Barriers for Integrating Zero Carbon into the Design Studio in the USA

Published: September 2023

The authors co-teach a design studio in which building performance is highlighted as a primary educational objective. For years, we helped students to use evidence-based feedback to improve the structural, energy, and cost performance of their designs. The design-assisting tools used by the students include verified computer programs for structural design, energy simulation, and cost estimating. Most recently, in response to climate change, we examined introducing carbon analysis as an additional design-assisting tool in order to expand the definition of building performance to include the environmental impact of embodied carbon. Initial results were revealing. Findings showed that while energy performance evaluation is often (in both academia and professional practice) limited to the evaluation of operational energy, embodied energy is likely to be the determining factor in the near future. As buildings become more energy efficient and/or increasingly reliant on renewable energy sources, the higher the contribution of its embodied energy is to its overall energy consumption. When buildings reach zero energy in operation, 100% of energy consumption will be due to embodied energy. Furthermore, consideration of a building’s embodied energy is the archi-tects’ most controllable factor. Therefore, educators must stress to students the importance of embodied energy even though educators may face a number of challenges that may hinder their ability to fully integrate carbon analysis into the design studio.
WaterLines: Speculative Design in the Threshold Between Land and Water
Authors:   University of Newcastle Australia, Lopez Irene Perez
Published: September 2023

Coasts and deltas constitute extraordinary environments built by geological forces in a geological timeframe. They are spaces constantly evolving, altered by the actions of natural and man-made transformation processes. This landscape is dotted with natural and man-made scenes where dynamism and unpredictability are exacerbated by the forces of rising sea levels and climate change. They are simultaneously territories of opportunity to interrogate about the challenges and posibilities for an unpredictable urban and landscape scenario in the climate emergency. Design Studios, conceived as an ongoing series of interconnected themes, explores the implications of living in the threshold between land and water as space altered by the transitory action of water, man-made transformations and unpredictable events exacerbated by climate change. Studio’s briefs are interrogating whether such dynamic and vulnerable environments and spaces can remain inhabited by humans, and if so, how that should occur? What are the models for coastal and delta habitation that can survive and prosper in a disintegrating territory between the unpredict¬able rivers and ocean, and the unstable land? What are the new urban landscapes and architectures design for a planet exposed to the effects of the climate we are changing? What are the operations that are needed to navigate new coastal and delta scenarios?
Countering Military Logistics and Algorithms in Palestine
Authors:   Columbia University, Abbas Jumanah
Published: September 2023

Algorithms -the well-calculated, supposedly all-solving encrypted formulas for any computational problem- have come to define our interactions. What we like, what we desire, what we see, and how we even perceive the space: encryptions have come to define how a space is constructed, and destructed. They have to come to order space, and even subvert it. That is, algorithms have come to read and write the world. But before the entanglement of codes within cities, what preceded algorithms? The modern concept of algorithms was analyzed by ancient mathematicians, and was later redefined by social scientists and engineers to sustain a more formal language and to execute efficiently. To that end, algorithms became essential to carry out specific tasks, process information, read data from one source, and provide an output.
Hyper-White Entanglements: A Brief History of Titanium White
Authors:   The Oslo School of Architecture and Design The University of Bergen Norway, Halland Ingrid
Published: September 2023

The inorganic compound titanium dioxide has progressively brightened our world throughout the 20th century. Titanium dioxide (hereafter TiO2) was invented and patented as a white pigment for the colour industry by Norwegian chemists Peder Farup and Gustav Jebsen in the early 1910s, and the industrial production of TiO2 for the global market began in the mine Titania and the factory Titan Co (today Kronos Titan), both in Norway, in 1916. TiO2 as a colour pigment was named Titanium White and the advertisements described the paint as “the whitest white” or “absolute white” due to its pure white colour tone, its stability and resistance against chemical influences, and its maximum ability to hide the substance underneath. As a result of its ability to also protect materials against the toxic influences of sunlight and weather, the substance was progressively used in combination with other colours (as coating for concrete, glazing for ceramics, and additives in plastic) thereby changing the aesthetics of surfaces in architecture and design. Today TiO2 is literally present in every part of modern life. Yet although circulating extensively through our material, biological, and economic systems, TiO2 is most of the time completely unnoticeable: it hides in the food we eat, in the paper we print on, in wall paint and concrete coating, in lipsticks, concealers, sunscreens, pills, and smart phones. If the European Green Deal is to succeed, new material awareness needs to be implemented, as “increasing material efficiency is a key opportunity to move towards the 1.5° C goal set by the Paris agreement.”1 We need to know more about how mineral extraction and patterns of consumption are linked. In order to better understand materials and their properties, and by extension a better oversight of the environmental impact of materials, design students need material knowledge. I argue in this paper that environmental history could be valuable for a better understanding of the environmental impact of materials. In this paper, a brief reading of the historical background and material properties of TiO2, will bring forth, unpack, and analyze some of the messy entanglements between modernist homogenization, global extraction economy, and our present-day material surroundings.

Published: September 2023

There has been growing interest in studying hexagonal boron nitride (hBN) for quantum technologies. Here, we investigate nitrogen isotope effects on boron vacancy (V
B) defects, one of the candidates for quantum sensors, in 15N isotopically enriched hBN synthesized using a metathesis reaction. The Raman shifts are scaled with the reduced mass, consistent with previous work on boron isotope enrichment. We obtain nitrogen isotopic composition-dependent magnetic resonance spectra of V
B defects and determine the magnitude of the hyperfine interaction parameter of 15N spin to be 64 MHz. Our investigation provides a design policy for hBNs for quantum sensing.

Purpose: This study aims to identify the phenomenon of overreaction in Islamic stocks during the COVID-19 pandemic and understand how various pieces of information during the pandemic influenced investors to overreact, leading to market inefficiency. Research Methodology: This study employs two main methods: an event study focusing on the overreaction phenomenon in the Islamic stock market, and cross-sectional regression to analyze the factors that influence it. Results: Overreaction was observed in the winner's stock portfolio during the announcement of Indonesia's first COVID-19 case. However, during other significant events, such as the National Economic Recovery program issuance, the arrival of the vaccine, and the highest increase in daily positive cases, overreaction was seen in both the winner and loser stock portfolios. Factors such as abnormal returns, information leakage, and company ownership are identified as significant influencers of this overreaction. These factors were found to be negatively related to cumulative abnormal returns post-event, indicating their role in the overreaction phenomenon. Limitation: This study focuses on the overreaction phenomenon of Shariah stocks in the Jakarta Islamic Index (JII) during the COVID-19 pandemic in 10 selected events from October 1, 2019, to July 23, 2021. Contribution: This study offers insights into the behavior of Islamic stocks in Indonesia during the pandemic, helping stakeholders understand market inefficiencies during crises.

Purpose: This study aims to identify the appropriate model for measuring the level of Maq'hid syar'ah in sharia banking. Methodology: The method used is a qualitative method with a literature approach. The data used are the results of published research using the Maq'hid syar'ah index with the study object of sharia banking. Results: The results of the study indicate that there are 5 measurement concepts used in measuring the sharia-compliancy of Sharia banks using the Maq'hid syar'ah index. Of the five concepts, there is a fundamental similarity that is the key to achieving the goal of Maq'hid syar'ah, which is purifying the soul, justice, and public welfare. A simple model that can be used to measure quantitatively is by using 3 main instruments; Interest-free business for the purpose of purifying the soul, Zakat for the purpose of achieving justice, and real investment for the purpose of realizing welfare (maslaha).

Efficacy of Integrating Varietal Resistance and Neem (Azadirachta indica A. Juss) Seed Oil for t,e Management of Callosobruchus maculatus Infesting Bambara Groundnuts in Storage
Authors: MAINA Y.T. , LALE N.E.S.
Published: September 2023

The efficacies of three rates (0.5, 1.0 and 1.5 mg/20 g seed) of application of neem (Azadirachta indica) seed oil (NSO) in controlling Callosobruchus maculatus infesting stored bambara groundnut were assessed on four local cultivars (Ole, Bakingangala, Bulmono and Jor) with different susceptibilities to bruchid attack. Untreated batches of the cultivars were included to serve as control. Treated and untreated batches were infested with adults of C. maculatus under prevailing storage conditions. Combining application of NSO especially at the rate of 1.5 mg/20 g seed with varietal resistance significantly reduced oviposition and progeny development in C. maculatus. No adult progeny developed in seeds of Bakingangala that were protected with 1.5 mg of oil. Treatment of seeds with NSO at this rate reduced seed damage from 97, 72.3, 58.1 and 87.90.4in unprotected Ole, Bakingangala, Bulmono and Jor to 3.0, 3.4, 0.0 and 18.3%, respectively. The interaction of the strategies also significantly reduced the severity of damage (number of adult emergence holes per seed) and overall susceptibility of the bambara groundnut cultivars. Susceptibility indices (SI) values for unprotected bambara groundnuts were 11.92, 10.52, 9.09 and 11.43 for Ole, Bakingangala, Bulmono and Jor, respectively. Comparable SI values for bambara groundnuts that were treated with NSO at the rate of 1.5 mg/20 g seed were 0.0, 1.12, 0.0 and 2.82 for-Ole, Bakinganpla, Bulmono and Jor respectively.
Molecular Identification of the Entomorpathogenic fungus, Metarhizium anisopliae Isolate Released for Biological Control of the Legume Flower Thrips, Megalurothrips sjostedti (Trybom)
Authors: EKESI S. , MANIANIA N.K.
Published: September 2023

The control of insect pests with entomopathogens requires the ability to distinguish released pathogen from locally endemic isolates of the same species. In this study, random amplified polymorphic DNA-polymerase chain reaction (RAPD-PCR) technique was carried out on Metarhizium anisopilae (Sorok isolate ICIPE 69 (isolated from a soil sample) released for biologist control of Megalurothrips sjostedti (Trybom) on cowpea in Kenya, the recovered isolate and five other isolates from different host and geographic locations. RAPD bands for the recovered isolate, ICIPE 69, was identical to those of the released isolate but different from other five isolates recovered from Maruca vitrata Fab. and Clavigraila spp. collected from the same treated plot and other isolates obtained from the germplasm. This relatively easy, fast and efficient technique has proved useful in identification of entomopathogenic hyphomycete used for thrips control and may also be valuable in modelling epizootiology of the released pathogen.

The life cycle and pupation site preference of Neochetina eichhorniae were studied in two outdoor experimental aquaria. The results showed that the period take for the egg hatch to larva, was 6.95±0.83 days. The larvae had three instars I. 11.5± 1.20 days: instar II, 12.5±1.88 days and instar III. 49.0±2.21 days. The mean period of pupation was 12.0±1.65 days N. eichhorniae pupate on living roots of water hyacinth.
A fast data-driven topology identification method for dynamic state estimation applications
Authors: Gotti Davide , Ledesma Pablo , Amaris Hortensia
Published: September 2023

This paper proposes a fast topology identification method to avoid estimation errors caused by network topology changes. The algorithm applies a deep neural network to determine the switching state of the branches that are relevant for the execution of a dynamic state estimator. The proposed technique only requires data from the phasor measurement units (PMUs) that are used by the dynamic state estimator. The proposed methodology is demonstrated working in conjunction with a frequency divider-based synchronous machine rotor speed estimator. A centralized and a decentralized approach are proposed using a modified version of the New England test system and the Institute of Electrical and Electronics Engineers (IEEE) 118-bus test system, respectively. The numerical results in both test systems show that the method demonstrate the reliability and the low computational burden of the proposed algorithm. The method achieves a satisfactory speed, the decentralized approach simplifies the training process and the algorithm proves to be robust in the face of wrong input data.
Ultra-Resistant Schizophrenia Comorbid with Temporal Epilepsy: A Case Report

Published: September 2023

Resistant schizophrenia is a significant public health issue due to high treatment costs and institutional dependence of patients. Despite the various definitions currently available to define resistant schizophrenia, along with existing clinical guidelines, their impact on daily clinical practice remains limited. While clozapine has been endorsed by national clinical guidelines, its utilization remains suboptimal, with delays in initiation and instances of ineffectiveness. Ultra-resistant schizophrenia is defined by clozapine's inefficacy even after a well-conducted treatment. The relationship between epilepsy and epilepsy-related psychoses is intricate. Individuals with epilepsy are more likely to develop psychotic disorders, while those suffering from primary psychotic disorders also have an increased risk of epilepsy. These findings suggest the presence of shared predisposing factors. We present the case of a patient with clozapine-resistant schizophrenia associated with temporal epilepsy.
