Authors: Torres Chelsea , Maeda Kensei , Johnson Madeline , Jason Leonard A.
Published: March 2024

There is limited information on the specific impacts of Long COVID in youth. Long COVID presents as persisting or new symptoms following initial COVID-19 infection. The aim of this study was to better understand how children and their families describe their experiences seeking diagnosis and support following the onset of symptoms of Long COVID. Six children and five caregivers located in the United States participated in this study. Study procedures included an online video interview with caregiver–child dyads. Interview transcriptions were then analyzed using a conventional approach to content analysis, with two independent coders generating themes. Eight themes emerged from this analysis including the severity of illness and symptomatology, difficulty surrounding the diagnostic process and not being believed, the impact on family and social connections, poor school functioning, positive coping, subsequent positive medical experiences, mental health, and knowledge of the medical field and healthcare experience. Themes revealed difficulty for youth and families in navigating the medical system and functioning in areas of daily life as well as areas of positive experiences related to coping and medical involvement. These findings also highlighted areas of needed improvement for the medical community and for research on Long COVID in youth.
A Systematic Review of Population Monitoring Studies of Sea Turtles and Its Application to Conservation
Authors: Hendrix Haley , Pérez-Espona Sílvia
Published: March 2024

Sea turtles are keystone species in marine environments due to their essential role as seagrass grazers and population regulation of jellyfish and sponges in coral reefs. However, due to their predominant presence in coastal areas, sea turtle populations face significant threats due to the impact of human activities. In this systematic review, 655 peer-reviewed publications were analyzed to assess the extent of population monitoring for all seven sea turtle species. The analyses revealed that, although population monitoring studies have increased for sea turtles in the past four decades, these have been biased towards certain species and oceanic regions. Furthermore, sea turtle population monitoring has been undertaken primarily using field-based methods, with satellite tracking and nest surveys being the most commonly used methods; however, the implementation of genetic methods for population monitoring has increased since the 2000s. Direct conservation recommendations from this study include the urgent need to establish population monitoring studies in the Critically Endangered Kemp’s ridley and hawksbill and the Data Deficient flatback. Furthermore, population monitoring programs should be implemented in Southeast Asia and Northern and Central Africa, where knowledge on sea turtle populations is still limited. Finally, due to the long-distance movements of sea turtles, we also advocate for international cooperation and collaboration of local communities to protect these ecologically important and iconic marine species.
Deep Deterministic Policy Gradient (DDPG) Agent-Based Sliding Mode Control for Quadrotor Attitudes
Authors: Hu Wenjun , Yang Yueneng , Liu Zhiyang
Published: March 2024

A novel reinforcement deep learning deterministic policy gradient agent-based sliding mode control (DDPG-SMC) approach is proposed to suppress the chattering phenomenon in attitude control for quadrotors, in the presence of external disturbances. First, the attitude dynamics model of the quadrotor under study is derived, and the attitude control problem is described using formulas. Second, a sliding mode controller, including its sliding mode surface and reaching law, is chosen for the nonlinear dynamic system. The stability of the designed SMC system is validated through the Lyapunov stability theorem. Third, a reinforcement learning (RL) agent based on deep deterministic policy gradient (DDPG) is trained to adaptively adjust the switching control gain. During the training process, the input signals for the agent are the actual and desired attitude angles, while the output action is the time-varying control gain. Finally, the trained agent mentioned above is utilized in the SMC as a parameter regulator to facilitate the adaptive adjustment of the switching control gain associated with the reaching law. The simulation results validate the robustness and effectiveness of the proposed DDPG-SMC method.
A Soft-Switching Proportional Dimming LED Driver Based on Switched Capacitor
Authors: Zhang Jie , Jiang Lu , Xie Weichong
Published: March 2024

This paper proposes a switched capacitor-based soft-switching proportional dimming LED driver to address color-mixing LED applications. The driver utilizes a half-bridge switch structure and incorporates a switched capacitor to regulate the dual resonant network. This configuration facilitates current sharing across each resonant network and enables fixed proportion dimming between them. The common inductance leveraged in this design results in fewer switching devices, thereby enhancing efficiency. Furthermore, all switches and diodes achieve soft switching, contributing to high efficiency. Finally, this paper built a 19 W experimental prototype, and the maximum efficiency reached 95.56%, which verified the correctness and feasibility of the driver.
Optimising Sowing Density for Microgreens Production in Rapini, Kale and Cress
Authors: Signore Angelo , Somma Annalisa , Leoni Beniamino , Santamaria Pietro
Published: March 2024

Microgreens represent a valuable agrifoods niche. Their cropping cycle is shorter than that of baby leaf greens, but the sowing density is typically much higher, and this has important cost implications for the grower. The current research demonstrates that the choice of sowing density strongly influences yield, as well as developmental stage and other quality parameters. Results also depended on the choice of the species and landrace. Considering the cost of seed, the option of accessing locally available landraces becomes particularly intriguing, again with relevant implications in choosing seed density. Rapini (landraces Cima grande and Fasanese), kale (landraces Barese and Altamura), and commercial cress were grown in an indoor environment. The effects of the three sowing densities (from 3 to 5 seeds∙cm−2) and the growing cycle (earlier harvest, 11 days from sowing, or later harvest, 14 days from sowing) on the microgreen yield and quality were studied. Sowing density affected yield (+19% at highest vs. lowest density), dry matter (but only with a longer cycle, and variable by landrace, with Fasanese rapini landrace 7% more than the Cima grande landrace), developmental stage, and soil coverage. The effects of sowing density can be modulated by cycle duration. Crop heights were 25% and 44% greater for the longer cycle of the Cima grande and Fasanese rapini landraces, respectively. In conclusion, the choices of the species/landrace and seed density must be carefully evaluated given costs and outcomes, with potential for the production of different final products (e.g., microgreens at earlier or later stages, other characteristics) and also for control over costs.
The Potential of Tidal Energy Production in a Narrow Channel: The Gulf of Morbihan
Authors: Thiébot Jérôme , Sedrati Mouncef , Guillou Sylvain
Published: March 2024

The tidal currents of the Gulf of Morbihan reach up to 3.5 m/s within a narrow (200 m large) channel connecting the sea to the inner part of the gulf. In this study, a Telemac2D model validated with a large dataset of field measurements is used to assess the resources of the gulf. The results show that two sites have the potential to host up to 48 turbines (diameter of 8 m). If the entire width of the channel is occupied by turbines, significant increases in current speed are expected to occur on each side of the main channel. Simulations also show that flow changes differ between ebbing and flooding tides. During ebbing tide, the changes are limited in amplitude and remain localised within the channel. During flooding tide, the changes are more significant, especially in the vicinity of one of the two sites where the water passing through the site is flushed into a large and shallow basin. In this area, energy extraction significantly modifies the spatial distribution of the current velocities. We consider different scenarios of tidal energy extraction. The results show that flow perturbation can be significantly reduced using a lower density of turbines, that extracting tidal energy at one site slightly reduces the resource of the other, and that the deployment of two turbines (testing conditions) has a negligible effect on ambient current speeds.
Artificial Intelligence (AI) in Brazilian Digital Journalism: Historical Context and Innovative Processes
Authors: Pinto Moisés Costa , Barbosa Suzana Oliveira
Published: March 2024

This article investigates the historical uses and types of artificial intelligence (AI) systems and resources in Brazilian journalistic products. It is a work anchored in critically analyzing the literature on the subject, mapping and observing cases, seeking to identify uses and innovative processes, and analyzing AI projects for journalism. A search was carried out in web repositories, specifically Google, Google Scholar, and Scopus, using the terms: “inteligência artificial” + “jornalismo”, “bot + jornalismo”, “Geração de linguagem natural [NLG] + jornalismo”, “aprendizado de máquina [machine learning] + jornalismo”, and “algoritmos + jornalismo”. The corpus analysis (N = 45) includes the evaluation of the impacts of AI on the production and distribution of news in the context of Brazilian digital journalism. We try to answer questions about the uses of databases, approximation with platforms, uses of shared codes, connections with other Ais, and sources of funding, and whether they are backend or frontend initiatives. In a parallel investigation, we try to identify if Brazilian newsrooms are officially using ChatGPT, a generative AI. The findings point to advances in using low-cost and low-impact AI, with the predominance of bots. The great availability of this kind of AI in web repositories is believed to facilitate native digital media to incorporate innovative processes in using these technologies.
On the Variability of Portuguese Duration Adverbials with Por and Durante
Authors: Santos Diana
Published: March 2024

The fact that there are (at least) two different translations of the English preposition for used to describe duration in Portuguese, namely durante and por, shows that duration is an interesting area in the tense and aspect panorama of this language, which deserves close study. In this paper, I present an empirical study based on four different corpora to investigate the matter, looking at the Portuguese varieties from Brazil and Portugal and different text genres (general and specialised newspapers, oral interviews, and fiction). The material spans circa two centuries. This paper identifies some specific uses and preferences of the two adverbials and confirms and challenges other claims in the linguistic literature. It shows that narrative fiction is definitely different from newspaper text due to its need to describe short duration and that planned duration can be expressed using both kinds of adverbials.

Authors: Rasouli Azam , Kudyba Artur , Bruzda Grzegorz , Safarian Jafar , Tranell Gabriella
Published: March 2024

High-temperature wetting of natural, high-purity quartz (SiO2) and liquid magnesium (Mg) was investigated at temperatures between 973 and 1273 K. Sessile drop experiments using the capillary purification (CP) procedure were carried out under an Ar gas atmosphere (N6.0), eliminating the native oxide layer on the surface of Mg melt. The results showed that the wetting behavior was strongly dependent on temperature. At 973 and 1073 K, the wetting system displayed relatively large contact angles of 90° and 65°, respectively, demonstrating modest wetting. The wetting increased to some extent by increasing the temperature to 1123 K with a wetting angle of 22°. However, the SiO2/Mg system demonstrated complete wetting at temperatures of 1173 K and above. Furthermore, interface microstructure examination showed different reaction product phases/microstructures, depending on the wetting experiment temperature.

Published: March 2024

Samples of ZrO2 ceramics with different concentrations of impurity titanium ions were synthesized by mixing zirconium and titanium oxide powders in different mass ratios. The X-ray diffraction analysis was used to determine the phase composition, lattice parameters, and crystallite size of the ceramics with varying dopant concentrations. Upon irradiation of the samples with 220 MeV Xe ions to a fluence of 1010 ions/cm2, a decrease in the intensity of the pulsed cathodoluminescence band at 2.5 eV was observed. Additionally, ion irradiation resulted in the emergence of a new thermoluminescence peak at 450–650 K attributed to radiation-induced traps of charge carriers. Further analysis revealed that the thermoluminescence curves of samples irradiated with electrons and ions comprise a superposition of several elementary peaks. Notably, a complex non-monotonic dependence of cathodo- and thermoluminescence intensity on titanium concentration was observed, suggesting the influence of concentration quenching and the presence of tunneling transitions.

Published: March 2024

Background and Objectives: According to the Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3), sepsis is defined as “life-threatening organ dysfunction caused by a dysregulated host response to infection”. The increased presence of free radicals causes an increase in oxidative stress. Vitamin C is an essential water-soluble vitamin with antioxidant activity and immunoregulatory effects that plays a potential role in the treatment of bacterial infections. Our aim was to evaluate the effectiveness of adding vitamin C to the conventional treatment of sepsis to decrease its mortality rate. Materials and Methods: In a prospective cohort study, we included patients with a diagnosis of sepsis and a SOFA score ≥ 9 who were evaluated in an Intensive Care Unit at a secondary-care hospital. According to the intensive care specialist, they were treated using two different strategies: Group 1—patients with sepsis treated with conventional treatment without vitamin C; Group 2—patients with sepsis with the addition of vitamin C to conventional treatment. Results: We included 34 patients with sepsis. The incidence of mortality was 38%, and 47% of patients used vitamin C as an adjuvant to the basic treatment of sepsis. In the basal analyses, patients treated with use of vitamin C compared to patients treated without vitamin C required less use of glucocorticoids (75% vs. 100%, p = 0.039). At follow-up, patients treated without vitamin C had higher mortality than patients treated with vitamin C as an adjuvant for the treatment of sepsis (55.6% vs. 18.8%, p = 0.03). We observed that the use of vitamin C was a protective factor for mortality in patients with sepsis (RR: 0.54, 95% CI: 0.31–0.96, p = 0.03). Conclusions: The use of vitamin C as an adjuvant to treatment decreases the risk of mortality by 46% in patients with sepsis and SOFA ≥ 9 compared to patients treated without vitamin C as an adjuvant to sepsis.

Published: March 2024

Background and Objectives. This overview of Cochrane systematic reviews (CSRs) reports on current evidence on the effectiveness of rehabilitation interventions for persons with upper limb fractures (ULFs), and the quality of the evidence. Materials and Methods. Following the inclusion criteria defined by the World Health Organization, all CSRs tagged in the Cochrane Rehabilitation database that were relevant for persons with ULFs were included. A mapping synthesis was used to group outcomes and comparisons of included CSRs, indicating the effect of rehabilitation interventions and the certainty of evidence. Results. A total of three CSRs were included in the evidence map. The certainty of evidence was judged as low to very low. Early occupational and hand therapy, cyclic pneumatic soft tissue compression, and cross-education, when started during immobilization, may improve grip strength and wrist range of motion, with results maintained up to 12 weeks from the cast removal, compared to no intervention. Approaches such as occupational therapy and passive mobilisation, started post-immobilization, are probably safe in terms of secondary complications. However, the overall evidence of rehabilitative interventions related to proximal humeral fractures has been judged insufficient for all the outcomes considered. A paucity of primary studies and CSRs for elbow fractures was noted. Conclusions. This overview provided the effect and the certainty of evidence of rehabilitation interventions available after ULFs using a mapping synthesis. To date, there is a need to further the effectiveness and safety of these interventions for persons with ULFs, improving methodological quality of the research in the field.
Rosmarinic Acid-Rich Perilla frutescens Extract-Derived Silver Nanoparticles: A Green Synthesis Approach for Multifunctional Biomedical Applications including Antibacterial, Antioxidant, and Anticancer Activities
Authors: Netala Vasudeva Reddy , Hou Tianyu , Sana Siva Sankar , Li Huizhen , Zhang Zhijun
Published: March 2024

This study describes a simple, cost-effective, and eco-friendly method for synthesizing silver nanoparticles using a rosmarinic acid extract from Perilla frutescens (PFRAE) as the bioreduction agent. The resulting nanoparticles, called PFRAE-AgNPs, were characterized using various analytical techniques. The UV–Vis spectrum confirmed the formation of PFRAE-AgNPs, and the FTIR spectrum indicated the participation of rosmarinic acid in their synthesis and stabilization. The XRD pattern revealed the crystal structure of PFRAE-AgNPs, and the TEM analysis showed their spherical morphology with sizes ranging between 20 and 80 nm. The DLS analysis indicated that PFRAE-AgNPs were monodispersed with an average diameter of 44.0 ± 3.2 nm, and the high negative zeta potential (−19.65 mV) indicated their high stability. In the antibacterial assays, the PFRAE-AgNPs showed potent activity against both Gram-positive (Bacillus subtilis and Staphylococcus aureus) and Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacterial pathogens, suggesting that they could be used as a potential antibacterial agent in the clinical setting. Moreover, the antioxidant activity of PFRAE-AgNPs against DPPH and ABTS radical scavengers highlights their potential in the treatment of various oxidative stress-related diseases. PFRAE-AgNPs also demonstrated significant anticancer activity against a range of cell lines including human colon cancer (COLO205), human prostate carcinoma (PC-3), human lung adenocarcinoma (A549), and human ovarian cancer (SKOV3) cell lines suggesting their potential in cancer therapy. The nanoparticles may also have potential in drug delivery, as their small size and high stability could enable them to cross biological barriers and deliver drugs to specific target sites. In addition to the aforementioned properties, PFRAE-AgNPs were found to be biocompatible towards normal (CHO) cells, which is a crucial characteristic for their application in cancer therapy and drug delivery systems. Their antibacterial, antioxidant, and anticancer properties make them promising candidates for the development of new therapeutic agents. Furthermore, their small size, high stability, and biocompatibility could enable them to be used in drug delivery systems to enhance drug efficacy and reduce side effects.
Free-Vibration Analysis for Truncated Uflyand–Mindlin Plate Models: An Alternative Theoretical Formulation
Authors: De Rosa Maria Anna , Elishakoff Isaac , Lippiello Maria
Published: March 2024

Plates are flat structural elements whose thickness is small in relation to the size of the surface. Their use may include engine foundations, reinforced concrete bridge elements or parts of various floating structures. Consequently, knowledge of their mechanical behavior under static and dynamic loads is of primary importance in engineering applications and of interest from a structural point of view. As a result, numerous works existing in the literature have investigated the mechanical properties of plates using various plate models, such as Reissner’s theory, Levinson’s theory, Kirchhoff’s theory and Mindlin’s theory, and their static and dynamic behavior has been examined. In the present paper the truncated Uflyand–Mindlin plate equation is proposed. According to Uflyand–Mindlin theory, an alternative theoretical formulation is presented for the free-vibration analysis of plates, and the equations of motion and the general corresponding boundary conditions are derived. This paper develops the truncated Uflyand–Mindlin plate equation, i.e., without the fourth-order derivative, by means of the direct method and variational formulation. The first-order shear deformable plate theory developed by Elishakoff, which takes into account rotational inertia and shear deformation and does not include a fourth-order time derivative, is variationally derived here. This derivation complements that performed by Mindlin some 70 years ago. The innovative aspect of the suggested strategy is that variational and direct methods for studying plate dynamics are analogous. Finding the third equation of the reduced Uflyand–Mindlin equations, the accompanying boundary conditions and their mathematical resemblance are the goals of the presented formulations. In order to solve the dynamic equilibrium problem of a truncated Uflyand–Mindlin equation via a variational formulation, it is demonstrated that the differential equations and the corresponding boundary conditions have the same form as those found using the direct technique. This paper successfully completes this task. Finally, in order to validate the effectiveness and correctness of the proposed procedure, a numerical example of the case of a plate simply supported at all four ends is proposed.
Associations between Autistic-like Traits and Imagery Ability
Authors: Hatakeyama Takao
Published: March 2024

This article examines empirical associations between qualities of the imagination, mental imagery, and cognitive abilities with special reference to autism. This study is the first to explore the empirical relationships between autistic-like traits and tests of imagery differences. Imaginative impairments and distinctive sensory characteristics in individuals with autism spectrum disorder (ASD) should be reflected in their interactions with mental imagery. However, the relationship between ASD and imaging traits remains unclear. Based on the hypothesis that the degree of autistic-like traits is reflected in imagery traits, this study examined how the individual Autism Spectrum Quotient (AQ) relates to imagery ability in 250 college students. Two vividness tests and one imagery-type test were used to assess imagery ability. Scores in each imagery test were compared between the high-scoring group classified by the AQ and the rest of the participants and between the low-scoring group classified by the AQ and the other participants. This study also directly compared imagery test scores between the high- and low-scoring groups. In terms of the total AQ score, the high-scoring group exhibited lower visualization scores. Regarding AQ subscales, “imagination” had the most extensive relationship with imagery traits, with the high-scoring group (unimaginative) showing lower imagery vividness across various modalities as well as lower visualization and verbalization scores. This was followed by the “attention to detail” subscale, on which the high-scoring group (attentive to detail) showed higher vividness of visual imagery. The results of the low-scoring group exhibited, on the whole, opposite imagery tendencies to the high-scoring group. The results indicate that autistic-like traits are associated with qualities of the imagination and especially mental imagery ability.

Developing and Managing Tourism in the Post Covid-19 Era: Perceptions from Hotel Industry Professionals in Cyprus
Authors: Boukas Nikolaos , Marneros Stelios
Published: March 2024

As in any other part of the world, the COVID-19 pandemic had a huge impact on tourism in the south-eastern island of Cyprus. Indeed, in a turbulent environment with many challenges that Cyprus’ tourism had to face, such as loss of competitiveness, monoculture of tourism, unplanned development, human resources management issues, etc., the pandemic was considered the most significant, that not only led to the halt of tourism activity – and hence, the partial collapse of the industry - for many months, but also brought into the surface several chronic structural problems of the island’s hospitality business, in terms of management. This paper seeks to examine how the tourism sector and more specifically, hotel enterprises in Cyprus handled the crisis and its consequences. To collect the data, exploratory research was utilised through the form of document scanning as well as face-to-face in-depth interviews with representatives of five-star hotels in Cyprus. Findings revealed that the greatest challenge that hotels in Cyprus needed to face during the pandemic era, was the high degree of uncertainty. All respondents stressed the role of the government and its support and emphasized the cooperation between the public and private sectors on the island. The results of the study would be useful for hotel managers to reduce the immediate impact of the crisis and support the long-term recovery of their operations and expansion, of Cyprus tourism, in a sustainable manner.
Phrase Detection's Impact on Sentiment Analysis of Public Opinion and online Media Toward Political Figures
Authors: Nurodin Muhammad Irsa , Yan Puspitarani
Published: March 2024

Public opinion of political figures and policy significantly impacts general elections. Sentiment analysis, as a method to comprehend opinion and emotion in texts, requires the step of text preprocessing to improve data quality. However, textual data often encounters irrelevant words and ambiguous language. These conditions can impact the accuracy of sentiment analysis. Given the significance of precisely interpreting public opinion toward political figures, these issues may result in biased or inaccurate sentiment analysis outcomes. Irregular punctuation or unclear language can disturb the text's intended context, compromising sentiment analysis quality. Additionally, irrelevant words can obscure the focus of the analysis, causing fundamental changes in the original text's meaning. This research focuses on the impact of a specific preprocessing technique, namely Phrase Detection with N-Gram, on sentiment analysis of political figures. By applying this method, the study aims to detail the effects of using Bigram, Trigram, and Unigram on the quality of sentiment analysis, particularly in the context of political figures on Twitter and online media articles. This research indicates that using Bigram in Phrase Detection provides more significant results than Trigram and Unigram for most political figures at Twitter, with the highest accuracy score of 88,23%. Sentiment analysis of articles in online media also indicates various results depending on the type of N-Gram. The results indicate that using N-gram phrase detection can influence the accuracy of sentiment analysis, and the resulting accuracy values are pretty high.

Possibilities of Using Transcranial Magnetic Stimulation for Migraine
Authors: Глеб О.В. , Чернуха Т.Н. , Лихачев С.А.
Published: March 2024

Данные некоторых исследований показывают, что транскраниальная магнитная стимуляция (ТМС) позволяет снижать количество дней мигрени в месяц, уменьшать интенсивность и продолжительность приступов мигрени в течение нескольких дней после применения ТМС, быстро купировать приступ мигрени и улучшать уровень качества жизни. Кроме того, ТМС безопасна и хорошо переносится, совместима с приемом фармакологической профилактической терапии при хронической мигрени. Однако отсутствие однородности результатов и данных о долгосрочной реальной эффективности приводит к тому, что результаты не предоставляют убедительных доказательств эффективности ТМС в лечении мигрени. В целях оптимального применения ТМС в клинической практике для лечения мигрени необходимы дальнейшие исследования, направленные на уточнение механизмов влияния данной процедуры на головной мозг. Важной проблемой, препятствующей широкому клиническому применению ТМС при мигрени, является неполное знание механизмов действия ТМС при мигрени, касающееся как профилактического лечения, так и лечения острой фазы. Следовательно, необходимы проведение дальнейших рандомизированных плацебо-контролируемых исследований для выяснения патофизиологии мигрени, анализ безопасности длительного и частого применения ТМС. Также требуется изучение потенциального взаимодействия между ТМС и новыми доступными препаратами для лечения и предотвращения приступов мигрени. Актуальна разработка оптимальных параметров ритмической ТМС, количества сеансов, показаний для направления на данный вид лечения.

Some studies show that transcranial magnetic stimulation (TMS) can reduce the number of migraine days per month, reduce the intensity and duration of migraine attacks within a few days after using TMS, quickly relieve a migraine attack, and improve quality of life. In addition, TMS is safe and well tolerated and is compatible with pharmacological preventive therapy for chronic migraine. However, the lack of uniformity of results and long-term real-world effectiveness data means that the results do not provide convincing evidence of the effectiveness of TMS in the treatment of migraine. Further research is needed to clarify the mechanisms of the effect of this procedure on the brain in order to optimally use TMS in clinical practice for the treatment of migraine. An important problem preventing the widespread clinical use of TMS for migraine is incomplete knowledge of the mechanisms of action of TMS for migraine, regarding both preventive treatment and treatment of the acute phase. Therefore, further randomized placebo-controlled studies are needed to elucidate the pathophysiology of migraine, as well as to analyze the safety of long-term and frequent use of TMS. Potential interactions between TMS and new available drugs for the treatment and prevention of migraine attacks are also warranted. It is relevant to develop optimal parameters for rhythmic TMS, the number of sessions, and indications for referral to this type of treatment.
