DIFFERENT APPROACHES FOR DESCRIPTION OF NEGATIVE ION FORMATION IN AN ARGON/ACETYLENE PLASMA AFTERGLOW
Authors: Denysenko I.B. , Azarenkov N.A. , Vinnichenko V. , Burmaka G.
Published: December 2024

Properties of an Ar/C2H2 plasma afterglow with dust particles are investigated at different assumptions concerning negative ion formation. First, numerical calculations are carried out assuming that C2nH2− negative ions, where n is a natural number, are the dominant anions in the plasma afterglow (the case (i)). Second, the studies are conducted assuming that C2nH− anions are only the negative ions, which are present in the afterglow plasma (the case (ii)). It is shown that the total density of negative ions n_ in the case (ii) is smaller than n_ in the case (i). Due to smaller n_, the positive ion densities are smaller and the absolute values of the mean dust charge and its variances are larger in the case (ii) than the corresponding values calculated using the approach (i). We also calculated the dust charge distribution functions (DCDFs) for late afterglow times. It is found that the DCDFs obtained in the case (ii) are shifted to the region of larger negative charges comparing with the dust charge distributions obtained in the case (i). The differences are mainly due to the loss of C2nH − anions in collisions with H atoms in the case (ii). In the case when the loss of negative ions in collisions with H atoms is not taken into account in the models, the both approaches give nearly the same time dependences for positive and negative ion densities, electron density, mean dust charge and its variance.

Authors: Mykhailenko B.R. , Anisimov I.O.
Published: December 2024

Using computer simulation, the initial stage of low-power electromagnetic waves` beam nonlinear interaction with the overdense plasma layer was studied. It is shown that the peripheral part of the beam excites a Langmuir
wave at the second harmonic, which propagates deeper into the plasma. It is also demonstrated that an axially asymmetric structure is formed in the near-axis region of plasma, which includes interconnected perturbations of the longitudinal and transverse electric fields, the longitudinal electron velocity, and electron density.
PROPERTIES OF THE IONIZATION REGION OF A MAGNETRON DISCHARGE IN ARGON WITH COPPER VAPOR ANALYZED USING A GLOBAL MODEL
Authors: Denysenko I.B. , Kravchenko O.Y. , Veklich A.N.
Published: December 2024

Using a global model, the ionization region (IR) of a magnetron discharge in argon with copper target is studied for the conditions corresponding to carried out experiments (the neutral gas pressure is in the range 0.01…0.1 Torr and the magnetron current is between 10 and 300 mA). It is found how the densities of thermal and hot electrons (emitted secondary electrons at ion bombardment of the target), copper and argon ions, copper atoms and metastable argon atoms in the IR depend on the magnetron current and gas pressure. The current dependences for the voltage drop across the sheath near the target, the sheath size and the energies of ions with which they bombard the target are also determined for different pressures. It is found that the temperature of thermal electrons decreases with increasing the magnetron current and pressure, in agreement with experimental data on the temperature of energy
level population (so called excitation temperature) of argon atoms determined by Boltzmann plot technique on the basis of argon spectral lines.

The influence of the external magnetic field on the characteristics of the discharge and generated plasma flows is shown. The values of the plasma potential in the flows are determined. It was found that the anodic potential drop in the discharge has a positive value and decreases with grows of the discharge current. The values of the electron temperature, plasma density and floating potential in the generated flows of the zirconium vapor plasma were determined. Data on the growth rate of deposited films are given and it is shown that the ionization coefficient in plasma flows is (60-90) % at various currents of the discharge.
INFLUENCE OF BOUNDARY CONDINIONS ON THE PLASMA POTENTIAL IN A HELICON DISCHARGE WITH PLANAR ANTENNA
Authors: Virko V.F. , Virko Yu.V.
Published: December 2024

In a helicon discharge excited by a flat inductive antenna, situated at the discharge chamber end, distributions of plasma parameters have been measured by a thermo-emissive probe. The aim of the work was to define an influence producing by the bias potential of the surface being processed on plasma parameters in discharge chambers with either the dielectric or with conducting side walls. It was found that in the dielectric chamber application of a positive voltage and taking electron current to the surface under treatment causes increasing the plasma potential because the opposite sine current can not flow to the insulating wall. In the metal chamber increase of positive voltage on the surface leads to the discharge instability and break off for considerable taking electrons away from the discharge volume.

A 3D-printed tungsten Sn Capillary Porous Structure (CPS) sample was exposed to oblique high-power plasma in the QSPA facility. The experiment aimed to analyze the damage to a liquid metal prototype, a potential component of the divertor in fusion tokamaks. Observations of plasma-surface interactions revealed particle ejection from the exposed target, which depended on the energy density of the incoming plasma stream. The leading edge of the CPS sample was identified as the primary source of the ejected particles. A reduction in mass loss rate of the
plasma-treated sample over the course of the experimental series was demonstrated. The W substrate of the CPS target did not sustain significant damage. A comparative analysis of the damage to Sn-CPS and castellated W samples exposed to inclined and normal plasma streams under conditions simulating transients in a fusion reactor was also performed.

Published: December 2024

The current study showed that there are morphological and anatomical differences between pigeons and guinea pigs. The trachea appeared in pigeons in the form of a long tube containing cartilaginous rings that were completely round and overlapping with each other, while the trachea appeared in the guinea pig in the form of a long tube with a diameter wider than that of the pigeon. It consisted of a group of cartilaginous rings that were not completely round. In both types, the lung consisted of left and right lobes. The lung in pigeons was rectangular in shape, fragile, and it has many blood vessels, it was closely attached to the ribs.  The lung of the guinea pig was composed of a group of lobes pyramidal in shape, and the left lung was smaller than the right lung. Histologically, the trachea in both animals consisted of four tissue layers, which are mucosa, submucosa, and a layer of connective tissue that contains cartilage and is covered from the outside with a layer of covering tissue called the adventitia. The lung in the pigeons also consisted of connective tissue with wide holes that were uniformly distributed throughout the lung tissue. The lung in the guinea pig consists of connective tissue with many branches, which represent the branches of the bronchioles, and those branches end with air sacs in the form of clusters. The differences in the nature of the behavior of the two animals could be a major reason for the presence of morphological and histological differences in the structure of the respiratory system of both animals.
EVALUATION OF THE USABILITY OF ANCESTRAL HULLED WHEAT T. BOEOTICUM IN COPING WITH GLOBAL CLIMATE CHANGE BASED ON CELLULAR ANTIOXIDANT RESPONSES
Authors: Temizgul Ridvan , Temizgul Sumeyye
Published: December 2024

Salinity is the second important factor after soil erosion that reduces crop yields by restricting plant growth and development. Misuse of fertilizers, excessive irrigation and industrial pollution are the main causes of widespread soil salinity, which poses a serious threat to agricultural productivity and food security for both humans and animals. Ancient wheats, unchanged for centuries, are seen as a promising solution for improving crop production on saline lands. Despite their importance for food security and local culture, these species are often neglected and undervalued in commercial production. In this study, we tried to predict the usability of this wheat in the reclamation of saline soils by measuring the tolerance of T. boeoticum to salt stress and the effectiveness of GB application in coping with stress. As salt stress, CaCl2 (Control-25-50-100-150-200 mM) and CaCl2 + Glycine-betaine (GB, 1 mM) were applied. The enzymatic and non-enzymatic responses of wheat roots and leafy stems to salt stress were analyzed separately to understand the specific reactions of each plant part. According to the results of the study, calcium chloride salt causes high levels of stress in T. boeoticum Boiss at concentrations above 100 mM. Combined application of glycine-betaine and calcium chloride significantly mitigated salt stress damage in wheat at 50, 100, and 150 mM salt concentrations. However, at 200 mM salt concentration, T. boeoticum Boiss suffered severe damage, resulting in approximately 80% reduction in stem length, leaf length, and chlorophyll content compared to the control. However, when 1 mM GB is applied together with 200 mM salt stress, the damage to wheat can be compensated by approximately 90% compared to the control. It has been observed that T. boeoticum Boiss variety has high antioxidant activity capacity in terms of both enzymatic and non-enzymatic antioxidant capacity. According to these results, it is predicted that ancient hulled wheat T. boeoticum Boiss can be used effectively in bringing saline/sodic areas into agriculture.

An investigation into some possible behaviours of rising plumes with a quadratic dependence relation assumption was made with the consideration that the plumes arises from a virtual sources. Our results showed that both forced and pure plumes provides buoyancy flux at the source. Meanwhile, the lazy plume rises with a significant volume flux and finite temperature with zero volume flux for both the forced plume and pure at the source. The forced plume also possesses some significant upward momentum flux and zero momentum flux for the pure plume. Determination of zero-buoyancy height and the fountain-top height are key when it comes to rising plumes. If the ambient water depth into consideration is less than the zero-buoyancy height then the warm water will definitely spread outwards as surface gravity current; otherwise, it will form a fountain.Our results showed that the upward momentum flux attains its pick at; and changes sign in the buoyancy force at this point while the momentum flux tends to zero with a finite final volume flux

Qf from its maximum rise height. Meanwhile, as M0 approaches the value , so the Qf and the Q0 tends to the value. It is worth stating also that the fountain-top height will be of great significant if the focus is on erosion of an ice cover. We therefore suggest maintaining a low source Froude number which will result to minimising impact on the lake floor or on the surface. Though, some level of carefulness is needed whenever we intend to make use of the present results to foretell the behaviour of real plumes. In particular, if laboratory experiments are required either to examine the theory or to model larger-scale flows in the environment. Lastly, with the entrainment model, it is required that the plume will be fully turbulent, a condition usually obtained with a Reynolds number Re > 2000. This can be likened to the power station warm discharge which will definitely be fully turbulent with it large volume flux. These are basic conditions on the validity of the assumptions. There are some limitations as stated in the conclusion. But then, the overall numerical results here are very good as they present us with more insight into rising plume with the quadratic dependence relation assumption.

Liquid soap is a cleaning agent made from synthetic surfactants, including anionic surfactants combined with amphoteric and nonionic surfactants; it can be supplemented with other additives that do not cause skin irritation. The active ingredient or substance, which can function as an antiseptic, antioxidant, or other significant roles, is an equally important component in soap making. Cocoa pod husk waste is one natural ingredient that can serve as an active substance in soap making. Cocoa husks contain flavonoids, alkaloids, tannins, saponins, and triterpenoids. The cocoa pod husk extract has very strong antioxidant activity and also possesses antibacterial activity. This research aims to determine the formulation and physical stability of liquid soap made from cocoa pod husk extract, as well as its antioxidant activity. The study commenced by extracting cocoa pod husk using the maceration method, which yielded a concentrated extract, and then proceeded with phytochemical analysis. Subsequently, we carried out the formulation of liquid soap, evaluated its homogeneity, organoleptic characteristics, pH, viscosity, specific gravity, foam height, and stability testing, and assessed its antioxidant activity. The evaluation results indicated that the liquid soap with cocoa pod husk extract had good physical properties in terms of homogeneity, organoleptic characteristics, pH, viscosity, specific gravity, and foam height. The results of the antioxidant activity test showed that the higher the concentration of cacao pod extract in the liquid soap, the lower the IC50 value. In formula V, the liquid soap with a 4% concentration of cacao pod extract obtained an IC50 value of 44.5.
In Between Hijab and Stories: Exploring the Intersectionality in Children's Literature of Shaikha Alzeyara
Authors:   Research Institute for Languages and Cultures of Asia, Mahidol University, Thailand, Alkhulaifi Aisha Ali
Published: December 2024

This study explored the portrayal of Qatari girls in children's literature of Shaikha Alzeyara, a prominent Qatari author. It uses the concept of intersectionality and empowerment to acknowledge the interconnectedness of social identities like gender, disability, and religion. The research highlighted the significance of children's literature in shaping children's assumptions about societal roles. Currently, the available literature for consumption conforms to the idea of boys as heroines and putting girls into a box like sheltered pearls. The analysis focuses on Alzeyara's stories. Through intersectionality, the study examines how these stories depict Qatari girls and the influence of Arab culture. Using qualitative methods through content analysis of the stories and in-depth interviews with the author and key personnel involved, the findings revealed a complex portrayal of girls. While some stories reflect traditional Qatari values of family and patriarchal society, others present independent, resilient girls who challenge limitations. The author's background as a Qatari woman is acknowledged as contributing to a more complex representation of girls. Alzeyara's work offers a starting point for a more intersectional approach to Qatari children's literature. Furthermore, intersectionality and empowerment as a framework for analyzing children's literature and promoting more inclusive narratives for young learners could contribute to the lack of knowledge in Arab women’s studies.

Authors: Yılmaz Emre
Published: December 2024

Bu çalışmanın amacı kişisel sağlık verisi ihlallerine neden olan faktörleri belirlemek, bu faktörleri BWM (Best Worst Method) yaklaşımı ile önceliklendirmek ve elde edilen öncelikler doğrultusunda sağlık verisi güvenliğini artırmaya yönelik çözüm önerileri sunmaktır. Kişisel sağlık verisi ihlallerinin değerlendirilmesi için literatür taraması sonucunda veri sızıntısı, insan hataları, kötü amaçlı yazılımlar, güvenlik düzeyi (şifreleme), siber saldırılar, yetkisiz erişim, ayrıcalık suistimali ve uygunsuz veri imha politikaları olmak üzere 8 kriter belirlenmiştir. Belirlenen kriterler çok kriterli karar verme yaklaşımı olan BMW yöntemi ile analiz edilmiştir. Değerlendirme, sağlık yönetimi ve sağlık hukuku alanlarında en az 7 yıllık akademik veya profesyonel deneyime sahip 6 farklı uzman tarafından yapılmıştır. Analiz bulgularına göre; kişisel sağlık verisi ihlallerine neden olan en önemli (en iyi) kriter %16,95 ağırlık puanı ile “Siber Saldırılar”’olarak tespit edilmiştir. Daha sonra sırasıyla “Veri Sızıntısı” (%16,77), “Ayrıcalık Suistimali” (%15,10) ve “Kötü Amaçlı Yazılımlar” (%15,07) gelmektedir. “Uygunsuz Veri İmha Politikaları” ise %5,01 ağırlık ile en az önemli (en kötü) kriter olarak tespit edilmiştir. Sonuç olarak, sağlık verilerinin ihlalinin engellenebilmesi ve etkili bir veri güvenliği yönetimi için çok yönlü stratejiler geliştirilmesi gerekmektedir. Siber saldırılara karşı, gelişmiş güvenlik önlemleri, düzenli güvenlik denetimleri ve ağ segmentasyonu gibi yöntemler önerilmektedir. Hasta kimliği; anonimleştirme, veri setlerinin kümelenmesi veya gerçek hasta kimliği yerine bulanıklaştırma tekniği gibi birtakım yöntemler kullanılarak mahremiyetin korunabilmesi sağlanabilir. Ayrıcalık suistimalinin etkilerini azaltmak ise rol tabanlı erişim kontrolü, kullanıcı faaliyetlerinin izlenmesi ve düzenli erişim denetimleri gibi yöntemler uygulanmalıdır.
Kıbrıs Sorununun çözümüne yönelik ekonomik paradigmalara yönetim stratejisi yaklaşımı

Kıbrıs Sorunu Osmanlı İmparatorluğu’nun 1571 yılında adayı egemenliğine alması ile birlikte oluşan çift toplumlu (Türk-Rum) yapıyla ortaya çıkmıştır ve günümüze kadar süregelmektedir. 1960 yılında kurulan Kıbrıs Cumhuriyeti de toplumlar arasındaki problemlerin çözümünü sağlayamamıştır ve nihayet Türkiye Cumhuriyeti’nin (T.C.) garantörlüğünde 1974 yılında gerçekleştirilen Kıbrıs Barış Harekâtı sonrasında 1983 yılında resmen Kuzey Kıbrıs Türk Cumhuriyeti (KKTC) kurulmuştur. Güney Kıbrıs Rum Yönetimi (GKRY) ise 2004 yılında bütün adayı temsilen Avrupa Birliği (AB) üyeliğine kabul edilmiştir. GKRY’nin AB’ye üyeliği hem Kıbrıs Sorunu’nu çözmemiş, hem de Türkiye-AB ilişkilerinde hassas bir konuya dönüşmüştür. Öte yandan Doğu Akdeniz’de yeni petrol ve doğal gaz kaynaklarının keşfedilmesiyle birlikte Kıbrıs Sorunu artık tüm dünyada tarafları olan bir durum halini almıştır; keza enerji son derece önemli bir girdidir ve uluslararası alanda bütün ülkeler için stratejik öneme sahiptir. Gerek AB-Türkiye ilişkilerinin ilerleme kaydetmesi, gerekse de Kıbrıs Sorununun çözümü bağlamlarında enerji kaynaklarının keşfi, ülkeleri anlaşmazlıkların çözülmesi yönünde teşvik etmektedir. Bu durum Türkiye’nin KKTC’nin yanındaki güçlü duruşu ve keşfedilen enerjinin nakledilmesi için sahip olduğu yatırım alanlarında vadettiği güvenilirlik sayesinde oluşmaktadır. Yönetim stratejisi olarak işletmelerin, Türkiye’nin güçlü desteğini alan KKTC’de her alanda istikrarlı ve kârlı yatırımlar yapmalarına zemin hazırlayacak gelişmeler; Kıbrıs Sorununun, son dönemde gündemde olan enerji kaynaklarının keşfi, nakli ve işlenmesi ile ilgili girişimlerle çözüme kavuşması ile birlikte sağlanacaktır. AB Türkiye ilişkilerinin de böylece olumlu yönde ilerleyeceği düşünüldüğünde, işletmelerin yönetim stratejilerini AB ile uyumlu bir perspektifte gerçekleştirmeleri yerinde olacaktır.

Published: December 2024

Abstract

More than 25 thousand Chinese listed companies in top ten manufacturing industry sectors from 2017 to 2021 were selected to explore the industry differences via the tool of analysis of variation (ANOVA) on China invention grant patents including the patent quantity, the varying trend of patent counts, and the capability for differentiating the stock return rate. The patent count of invention grants well showed the capability of differentiating the stock return rate for one industry sector, preferably showed the capability for two industry sectors, fairly showed the capability for three industry sectors, and partially showed the capability for four industry sectors. The manufacturing industry sectors with significantly increased invention grant’s patent count means since 2017 showed higher relevance to the capability. The manufacturing industry sectors of higher patent count means also showed higher relevance to the capability. The manufacturing industry sectors of higher/lower stock return rate means did not show relevance to the capability. However, every manufacturing industry sector had its particularity. The industry difference on the invention grant patents among ten manufacturing industry sectors in China stock market was distinct.

Artificial intelligence in writing and research: ethical implications and best practices
Authors: AlSamhori AR. F. , Alnaimat F.
Published: December 2024

Artificial Intelligence (AI) is a field that utilizes computer technology to imitate, improve, and expand human intelligence. The concept of AI was originally proposed in the mid-twentieth century, and it has evolved into a technology that serves different purposes, ranging from simple automation to complex decision-making processes. AI encompasses Artificial Narrow Intelligence, General Intelligence, and Super Intelligence. AI is transforming data analysis, language checks, and literature reviews in research. In many fields of AI applications, ethical considerations, including plagiarism, bias, privacy, responsibility, and transparency, need precise norms and human oversight. By promoting understanding and adherence to ethical principles, the research community may successfully utilize the advantages of AI while upholding academic accountability and integrity. It takes teamwork from all stakeholders to improve human knowledge and creativity, and ethical AI use in research is essential.
Analysis of the quality and credibility of health-related content on YouTube: cross-sectional study
Authors: Mukhamediyarov M. , Nurmashev B. , Bekaryssova D.
Published: December 2024

Introduction. Social media plays a massive role in informing people and promoting valuable, poor-quality content. The openness of social media to all users makes users vulnerable to viewing low-quality, misleading videos. In today's world, the number of users using information on social media is growing, so assessing the quality and credibility of the material provided is important. This study aims to thoroughly analyze the quality and credibility of YouTube health-related content (HRC) impacting public health.
Methods. Data were collected through the YouTube API using key queries: 'vaccination,' "COVID-19," "folk remedies," "health," "mental health," and' nutrition.' One hundred seventy-seven videos with more than 10,000+ views and duration between 3 and 30 minutes were selected for analysis. Quality was assessed using the Global Quality Scale (GQS), and reliability was assessed using a modified DISCERN scale. All data were analyzed using SPSS version 26; the Kappa coefficient was used to assess consistency.
Results. The final analysis included 162 videos, of which 74.1% were helpful, and 25.9% contained misleading information. Most of the videos (27.8%; n = 45) were classified as "Medical educational," followed by "Educational" (17.9%; n = 29) and "News" (15.4%; n = 25). The least represented categories were "Entertainment" (5.6%; n = 9) and "Other" (4.9%; n = 8). Helpful videos showed higher scores on the GQS and DISCERN scales (P < 0.001). The GQS scores of the valuable videos were significantly higher than the misleading videos, with a median (min-max) score of 4 (4–5) (P < 0.001). The DISCERN found the scores of the valuable videos to be significantly higher (P < 0.001). The median number of views for misleading videos was 591,060 (13,370–107,969,406), compared to 353,567 (range: 10,314–13,557,501) for valuable videos. Videos with mostly misleading content had many views, and the difference between the two comparable categories of groups was not statistically significant (P>0.05).  Daily views and likes in valuable videos were lower than in misleading ones; the difference was significant (P < 0.05). The likes rate was lower in the valuable videos, but the difference was insignificant (P = 0.778). The average number of views of misleading videos is much higher, although the quality and credibility are lower.
Conclusion. YouTube significantly impacts the dissemination of medical information, but the platform's accessibility also facilitates the dissemination of inaccurate content. The results of our study emphasized the need to create a system of monitoring and control over the quality of medical information in the YouTube social network, as well as the involvement of medical professionals in creating educational medical content. The development of information verification mechanisms will help to reduce the risk of users making wrong decisions based on unreliable video content.
Partially or fully (“silently”) withdrawn or retracted Center for Open Science preprints
Authors: Teixeira da Silva J.A.
Published: December 2024

In academia, one of the publishing models available to authors are preprints, which are non-peer-reviewed documents that typically serve as a prelude to submissions to peer-reviewed journals. Preprints can be published rapidly, following some moderation and screening, and because they can be updated if desired and when required by authors, and since they are generally not considered to be prior publications, preprints have become a popular medium of publication in recent years. Preprints, particularly those that are assigned a digital object identifier, are formal scientific documents, so they form part of the permanent knowledge base. Consequently, when preprints are withdrawn or retracted, for whatever reason, it is essential to document this event and treat such documents and authors as equally as any other document that or author who suffers a withdrawal or retraction. In addition, reasons for withdrawals or retractions should be formally noted by the preprint server, while basic bibliometric data, such as authors’ names, the preprint’s title, and the abstract, should remain intact, for posterity, while a retracted preprint needs to be labeled as such. When preprint servers opaquely scrub clean most or all identifiers from retracted (or withdrawn) preprints, and remove the accompanying file, then these are known as partial or full (“silent”) preprint retractions or withdrawals. This paper presents some cases of silently retracted preprints on the Center for Open Science preprint server.
Could generative artificial intelligence serve as a psychological counselor? Prospects and limitations
Authors: Teixeira da Silva J.A. , Yamada Y.
Published: December 2024

Humanity’s ability to embrace artificial intelligence (AI), or the skills and “knowledge” that it can impart, depends not only on the control of input fed to AI, but also on output management. When properly managed, the AI output, including of large language models (LLMs) such as ChatGPT, can complement human endeavor and excellence. Yet, if abused or left to its own computational vices, AI might cause harm to humans and thus humanity. Within this in mind, this perspective paper offers a reflection on whether LLM-based AI, having the capacity to integrate text, voice and speech, could assist in personal or psychological counseling processes. Cognizant that psychological counseling places the human factor as a central premise of therapy, AI could be perceived as a risk of replacing human-centered counseling roles, even though it might provide assistance to humans under strictly controlled conditions. While the replacement of human-based counseling is not being advocated, there is value in considering the possibility of applying LLM-based AI tools as counseling aides, as AI-human teams, under strict human supervision, and following stringent testing, provided that an ethical working framework and reliability in AI performance can be established.
Revisiting melorheostosis: highlighting the classic dripping candle wax sign in a young female
Authors: Ismail O. , Alnaimat F.
Published: December 2024

Melorheostosis is a rare dysplastic bone disease that is typically diagnosed in radiographic studies. The pathogenesis of melorheostosis remains unclear, with many genetic pathways suspected to play a role. Melorheostosis is sporadic in nature, usually limited to a single limb, extending in a sclerotomal fashion, and no clear gender predilection has been proven in the literature. Multiple case reports have described the disease characteristics in adults and involving large bones. We present a case of a 16-year-old female patient who presented with right upper limb pain with swelling. Plain X-rays showed melorheostosis of the right upper limb, demonstrating the typical “dripping candle wax” sign. Further radiographic evaluation of the patients showed that the disease extended in a sclerotome distribution, including the humerus, radius, and second, third, and fourth metacarpals and phalanges. A literature search across PubMed, Scopus and the Directory of Open Access databases was conducted to study this disease in the young age group.
Editorial - Digital Regulation

Published: December 2024

In the European Union, policymakers have been trying to meet the rapid development of artificial intelligence (AI) and digital technologies, culminating in a range of regulatory instruments and authorities that pose serious challenges to both legal theory and legal practice. From the recent EU AI Act, the Digital Services Act (DSA) and the European Media Freedom Act (EMFA), to the Digital Markets Act (DMA) and the General Data Protection Regulation (GDPR), both courts and regulators (administrative authorities and digital platforms) have yet to assess how the intersection of these instruments will work in practice across different sectors, legal systems and technological contexts. As this issue of e-Publica shows, the task of balancing innovation with the protection of fundamental rights and digital innovation is certainly not an easy one
