Abstract
This study introduces an innovative method for minimizing artifacts in electroencephalography (EEG) signals by integrating brainstorm optimization (BSO) with a variational autoencoder generative adversarial network (VAE-GAN), resulting in the BrOpt_VAGAN model. EEG signals are critical for the diagnosis of neurological disorders, for brain-computer interface (BCI) applications, and for the monitoring of neurological disabilities. However, EEG data often contains artifacts from physiological sources — such as electrooculographic (EOG), electromyographic (EMG), and electrocardiographic (ECG) signals — which can distort the accuracy of brain activity readings. Our proposed BrOpt_VAGAN model combines BSO with a VAE-GAN framework to more effectively remove these artifacts, thus improving the clarity and accuracy of EEG signals. In this model, the VAE first reduces the raw EEG signals into a lower-dimensional representation that captures the essential signal patterns while filtering out the noise. The GAN component then refines this representation via adversarial training, effectively minimizing artifacts and improving the quality of the processed EEG data. BSO optimally adjusts the encoding and decoding parameters within the VAE-GAN structure, enabling the model to handle different noise levels and helps to find different neurological disorders. Preliminary results show that BrOpt_VAGAN performs significantly better with an accuracy of 98.5 % and an error rate of 11.23 %, enabling a clearer and more precise EEG signal reconstruction.

Published: February 2025

Abstract
Neutron beams are employed in a multitude of applications, including neutron activation analysis, neutron radiography and tomography, nuclear waste assays, reactor start-up sources, studies of material response, geological analysis, calibration standards and cancer therapy. The global demand for access to neutron beams is increasing, necessitating the development of relatively simple, efficient and easy-to-use neutron sources to address the more complex challenges of scientific research and industrial application. One relatively readily available method is to use a linear electron accelerator to produce beams of fast neutrons. The neutron generator, comprising of an electron linear accelerator and a tungsten X-ray converter, is capable of producing a maximum neutron flux of 1.53·1010 n/s to 1.45·1013 n/s at electron energies of 10–50 MeV, with an average electron beam current of 120 μA, corresponding to an intensity of 7.5·1014 e/s. The results of the neutron generator modelling conducted with the FLUKA Monte-Carlo code are presented in this article for an equivalent incident beam power of 1.2–6.0 kW. The optimal tungsten converter thickness is proposed as a means of achieving the maximum neutron flux in all directions.

Objective: This study aims to demonstrate energy efficiency measures that enable effective control over the operation of air conditioning units in the Faculty of Science and Technology/UFG (FCT) building.

Theoretical Framework: This study explores the potential for optimizing energy consumption in a VRF (Variable Refrigerant Flow) system and a CCM09 control center, which is capable of managing multiple air conditioning units.

Method: Although the CCM09 control center had been installed in the FCT building, it was not operational. To activate it, the first step was to catalog all installed air conditioning units. Next, the control center was connected to the VRF system, and finally, software enabling remote control (via the internet) was implemented. This software allows for effective system management, including monitoring and shutting down units during non-essential periods, such as nighttime, weekends, and holidays.

Results and Discussion: The actions taken in this study enabled a more efficient scheduling of operating hours and facilitated the implementation of a remote monitoring system for the FCT air conditioning system.

Research Implications: he findings of this research contribute to reducing the energy consumption of the FCT air conditioning system, aligning with broader efforts to enhance energy efficiency.

Originality/Value: This study is pioneering in the buildings of the Federal University of Goiás (UFG). Currently, another building with the same technology exists, but it remains disconnected. The results obtained will support the adoption of this technology in the mentioned building and future UFG facilities.

Authors: Anjos Sérgio Saraiva Nazareno Dos , Santos Danusa Campos Teixeira Dos , Pereira Thiago Henrique Martins 
Published: February 2025

Objective: The main objective of this article is to diagnose the state-of-the-art technology for hydrogen (H2) production from algae to assess competitiveness in the renewable fuels market.

Theoretical Framework: Actions to decarbonize the energy matrix are part of the Kyoto Protocol and the Paris Agreement to control climate change, without negatively impacting energy security. H2 has become one of the competitive energy sources for decarbonization actions and one of the ways to control the increase in global temperature. Algae are potential renewable sources of competitive H2 due to their rapid growth, metabolic versatility and sulfur-free biomass.

Method: A patentometric study was carried out based on patent documents published between 2013 and 2023, mined in the software VantagePoint to calculate the Emergency Score.

Results and Discussion: The retrieved patent documents highlighted bioremediation processes in biorefineries and chemical and physical processes to separate H2 from other elements as emerging technological routes. Investments in these routes associated with genetic engineering of algae and better bioreactor design are possible combinations that will generate competitive advantage.
Research Implications: Even if algae are not yet viable at the present time, the diversification of sources encourages the execution of new projects to evaluate biomass and develop industrial processes. The issues highlighted are actions that will potentially strengthen socio-environmental responsibility initiatives, associated with the concept of circular economy.

Originality/Value: This study contributes to the literature by indicating paths for the development of technological solutions for hydrogen production from algae biomass, becoming another alternative aimed at energy security.
Intestinal parasitic infestations in adult chronic spontaneous urticaria patients and the relation between them: A case–control study
Authors: Farouk Shaimaa , Anza Alaa Abu , Hossam Dalia , Sadek Ahmed 
Published: February 2025

Objectives
Chronic urticaria (CU) is a prevalent allergic skin condition with variable symptoms and a complex etiology. It is characterized by the presence of itchy hives, angioedema, or both on at least twice-weekly basis for more than 6 weeks. The cause of CU has yet to be thoroughly established. It is unclear how intestinal parasites affect CU and whether they can trigger the clinical manifestations of allergic reactions. The study aimed to assess the prevalence of intestinal parasitic infestations in adults with chronic spontaneous urticaria (CSU) and explore their potential association.

Material and Methods
This was a case-control study that included 100 healthy individuals as group control and 100 patients suffering from CSU. All patients were examined for stool analysis to detect intestinal parasitic infestations.

Results
The age of patients ranged from 20 to 57. The prevalence of intestinal parasitic infestations was 66% in the CSU patients, which was statistically significantly higher as compared to the control group (16%) (P < 0.001). There was a strong relationship between positive parasitic infestations and the severity of urticaria. There was a higher rate of positive parasitic infestations in the cases that did not respond to the full dose of antihistamine and needed a second line of treatment (92.9%) as compared to the cases treated only with antihistamine (55.6%) (P < 0.001).

Conclusion
The prevalence of intestinal parasitic infestations was higher in CU patients and also correlated with its severity.
A SAÚDE COMO DEVER FUNDAMENTAL EM TEMPOS DE COVID-19: CONSIDERAÇÕES SOBRE A OBRIGATORIEDADE DE VACINAÇÃO A PARTIR DAS ORDENS JURÍDICAS BRASILEIRA E PORTUGUESA
Authors: Dias Eduardo Rocha , Silva Clarissa Sampaio 
Published: February 2025

O presente artigo objetiva investigar a existência de fundamentos para que Estados, no caso Brasil e Portugal, imprimam caráter de obrigatoriedade à vacinação contra Covid-19, e, em caso positivo, identificar medidas cabíveis diante de eventual recusa em aceder à imunização. Pretende-se contextualizar a vacinação dentro do cenário de um estado de necessidade administrativa, decorrente da Pandemia de COVID-19, a justificar uma atuação autoritária; explorar o aspecto da saúde como dever fundamental, bem como os limites de tal vertente; apontar meios para que, mediante o resgate de uma postura de diálogo, seja possível à Administração Pública lograr a adesão do maior número de pessoas ao programa vacinal e, por fim, alertar sobre os perigos de um “Estado Biométrico”. Trata-se de pesquisa de natureza qualitativa e exploratória, de base bibliográfica, com recurso às legislações brasileira e portuguesa, doutrina, bem como a julgados do Supremo Tribunal Federal, no caso brasileiro, proferidos diante do conflito, abstrato ou concreto, entre o dever fundamental à saúde (e a aceitação de vacinação) e a liberdade, em suas múltiplas formas. Concluiu-se que, no contexto de riscos como o de epidemias, atualiza-se o dever fundamental de se vacinar, mas sem perder de vista as garantias de um Estado de Direito. Não se pode aceitar a vacinação coercitiva, mas se admitem restrições a quem se recusa a tomar o imunizante, sob a perspectiva de se evitar danos à saúde coletiva. Na superação do desafio da ignorância, atualiza-se também o papel informativo da administração.
MARKO ANTON PLENČIČ, RAZPRAVA O KONTAGIJU, 1762
Authors: Jurca Jože , Jurca Tomaž 
Published: February 2025

Marko Anton Plenčič (Plenciz), rojen leta 1705 v Solkanu pri Gorici, je bil ugleden zdravnik in profesor na dunajski medicinski fakulteti. Leta 1762 je objavil obsežno delo z naslovom Opera Medico Physica, ki vsebuje štiri razprave, in sicer o okužbi, o črnih kozah, o škrlatinki in o potresih. V prvem, bržčas najpomembnejšem delu (De Contagio), je obrazložil svojo zamisel o živih povzročiteljih kužnih bolezni pri ljudeh, pri živalih in pri rastlinah. Da bi utemeljil svoje prepričanje, posega Plenčič na različna področja tedanjega naravoslovja od humane in veterinarske medicine do kemije, od botanike in zoologije do mikrobiologije in imunologije. Pri tem navaja številne avtorje, tako antične kot sočasne, katerih dela in ugotovitve so blizu njegovih zamisli, ali pa jo vsaj posredno podpirajo. Plenčič pri svojih razlagah seveda upošteva vse stare teorije o tem predmetu, vendar z določenimi omejitvami. Prilagaja jih in nadgrajuje z elementi teorije o »contagium vivum«. Njegov namen je jasen. Prepričati je treba predvsem strokovnjake, da sprejmejo zamisel o živih kužnih klicah, da s poglobljenim študijem nadaljujejo njegovo delo, da preučijo kontagije vseh vrst in iznajdejo učinkovito zdravilo za vse kuge.
Marc Anton Plenciz, Treatise on the Contagion, 1762
Marc Anton Plenčič (Plenciz) born in 1705 in Solkan near Gorizia, was a distinguished physician and professor at the Medical Faculty in Vienna. In 1762 he published an extensive study with the title Opera Medico Physica, which contains four treatises about infections, smallpox, scarlet fever, and earthquakes. In the first, most important section (De Contagio), he described his scientific idea on living agents as the cause of contagious diseases in humans, animals, and plants. To explain his beliefs Plenčič listed several examples from different fields of natural science of that time, like human and veterinary medicine, as well as chemistry, botany, and zoology, and finally also microbiology and immunology. In his book he quoted authors from antiquity and contemporary scientists, whose works and conclusions, were close to his conception about the causes of contagious diseases. To support his explanations, Plenčič considers all previous theories on this subject, but with certain limitations. He adapts and improves the existing ideas with the theory of the »contagium vivum«. His purpose was to convince the authorities, to accept his theory about living contagious agents and to continue his research, with the intention to further investigate all kinds of contagium and to invent an effective remedy.

Leading Indicators of Tax Revenue: Does Government Spending Matter?
Authors: Adji Artidiatun , Ghuzini Diny 
Published: February 2025

Indonesia's tax ratio has shown a declining trend over the past fifteen years. Tax revenue is an essential component in the provision of public goods and services. Therefore, it is vital to empirically examine the leading indicators that determine tax revenues. One of the concepts underlying the determination of tax revenue is the spend-tax hypothesis. This hypothesis states that the fiscal authority will determine the level of government spending and tax revenues will be targeted accordingly. The objective of this study is to empirically examine the leading indicators of aggregate tax revenues and its components and whether government spending is a determinant. In developing the estimated model, this study utilizes existing literature and the results of focused group discussions conducted with the Directorate General of Budget, Indonesian Ministry of Finance. This study utilizes monthly data to be more accurate in identifying trend changes and to get better estimates for strategic long-term forecasting, as required by fiscal authorities. To capture information affecting tax revenue and to overcome spurious regression, this study uses Partial Adjustment and Autoregressive Models. Those are consistent with the nature of determination of government budget in Indonesia which considers the values of past variables. The estimates show that government expenditure is an essential variable affecting tax revenue and its components, implying that government spending encourages economic activity. Since government spending is the dominant variable in affecting tax revenue and its components, expansionary fiscal policy can be implemented to increase total tax revenue and its components.
Surgical correction of severe cervical kyphosis secondary to tuberculoid Pott’s disease: illustrative case
Authors: Thibault Drew , Mullins Jordyn , Pando Alejandro , Movahed-Ezazi Misha , Wong Timothy 
Published: February 2025

BACKGROUND
Pott’s disease (PD) is an infection of the vertebral bodies due to Mycobacterium tuberculosis. Commonly presenting with back pain, the insidious nature of the disease can result in the development of kyphotic deformities, epidural collections, and neurological dysfunction. The authors describe the case of a 21-year-old male who presented with symptoms of cervical myelopathy and was found to have a kyphotic deformity involving the C5 and C6 vertebrae with epidural extension. The patient was treated with a combined anterior-posterior surgical approach: anteriorly with C5–6 corpectomy and cage placement and posteriorly with C2–T2 instrumentation. The final pathology was positive for M. tuberculosis, and the patient was placed on antibacterial therapy.

OBSERVATIONS
PD often presents late with symptoms that do not match the severity of the radiological spinal deformities. Surgical intervention is warranted in patients with severe deformity, neural element compression, and concordant neurological deficits. A literature review demonstrated that the combined anterior-posterior approach provides the greatest correction of kyphotic deformities. However, both anterior and combined approaches are associated with good outcomes and relatively few surgical complications.

LESSONS
The combined anterior-posterior surgical approach for cervical PD is recommended when kyphosis is severe. With appropriate surgical and medical management, most patients recover well without recurrence of symptoms.

Challenges in the treatment of giant cavernous carotid aneurysm associated with hemophilia A: illustrative case
Authors: Hirata Yuichi , Hiramatsu Masafumi , Sugiu Kenji , Fujita Juntaro , Sotome Yuta , Kawakami Masato , Kimura Ryu , Ebisudani Yuki , Haruma Jun , Tanaka Shota 
Published: February 2025

BACKGROUND
Hemophilia A is characterized by a deficiency of factor VIII, leading to severe bleeding disorders. Abnormal blood coagulation can complicate the treatment of cerebral aneurysms.

OBSERVATIONS
A 20-year-old man with congenital hemophilia A presented with abducens nerve palsy caused by a giant cavernous carotid aneurysm (CCA). Because of the coagulopathy, simple internal carotid artery ligation was chosen, and the aneurysm initially shrank following treatment. However, it recurred due to collateral arteries from the posterior communicating artery and branches of the external carotid artery. These arteries were occluded using endovascular techniques, resulting in complete obliteration of the aneurysm.

LESSONS
To the best of the authors’ knowledge, this is the first reported case of treating a giant CCA associated with hemophilia A. In patients with coagulopathy, surgical options are limited, and standard treatments may not achieve a complete cure. Careful consideration of treatment strategies is crucial when managing giant CCA in the context of a coagulation disorder.

Efficacy of Charcoal and Water Based Formulations of Bacillus subtilis to Promote the Growth of Triticum aestivum (L.)
Authors: Nawaz Shafqat , Tanveer Sana , Ali Basharat 
Published: February 2025

Background. Plant growth-promoting rhizobacteria (PGPR) are used with different carrier materials that provide habitat and nutrients to the bacteria. Charcoal is an important carrier material which also acts as the source of carbon for microorganisms.
Objective. This study aims to analyze the effects of charcoal and water-based formulations of Bacillus subtilis on the growth parameters of wheat plant, namely Triticum aestivum L.
Methodology. Five strains of B. subtilis were selected including Z-12, Z-16, Z-24, Z-44, and Z-66. The cellular morphology of the strains was examined by performing Gram and endospore staining. For their further characterization, several biochemical tests were performed. Strains were evaluated for auxin production by growing them in Luria-Bertani (LB) broth, supplemented with 0, 400, and 800 μg/ml concentrations of L-tryptophan. Charcoal and water-based formulations of single and mixed cultures, namely C1 (Z-12, Z-44, Z-66), C2 (Z-12, Z-16, Z-24), and C3 (Z-16, Z-44, Z-66) were applied to soil and seeds, respectively. Multiple growth parameters were examined under laboratory and natural conditions including root length, shoot length, fresh weight, dry weight, tillers, spike length, and seed weight.
Results. Colorimetric analyses revealed strains Z-44 and Z-66 as more active in auxin production. Under laboratory conditions (water-based), mixed culture C1 showed maximum improvement in all parameters. Among water-based formulations, mixed cultures C1 and C3 successfully exhibited maximum growth under natural conditions. Among charcoal-based formulations, strains Z-12 and Z-24 recorded maximum improvement in seed weight and spikelet count at the final harvesting stage.
Conclusion. The study concluded that both types of PGPR formulations significantly enhanced the growth parameters of wheat.
