The Internet and digital platforms are often portrayed as public spaces, hosting both private conversations and discussions of public interest. Political campaigns are conducted and business transactions are also carried out there. This paper challenges this view by highlighting the differences between the Internet and traditional public places. Instead, it argues that the Internet increasingly resembles a mosaic of private domains controlled by a few powerful entities that dictate the flow of information. This paper examines the issue from the perspective of the benefits that public places provide in modern democratic societies and posits the debate within Habermas’s understanding of the public sphere, providing for differences in how public place is typically perceived regarding the Internet and especially digital platforms. Finally, it outlines the ongoing legislative debate in Bosnia and Herzegovina on this issue, with comparative insights from the legal frameworks of Serbia and Croatia.

Obična lavanda (Lavandula angustifolia Miller) je niska, višegodišnja grmasta biljka koja raste u zemljama oko zapadnog Mediterana. Potekla je iz sunčanih stjenovitih područja i prvenstveno se uzgaja zbog svojih esencijalnih ulja. Različite studije pokazale su da određene vrste ljekovitih biljaka, kao što je L. angustifolia Miller, koje sadrže linalol i linalil acetat ester, imaju blagi sedativni učinak i koriste se u aromaterapiji i fitoterapiji za ublažavanje stresa. Svrha ove studije je utvrditi antioksidacijsku aktivnost uzoraka obične lavande. Uzorci biljnog materijala prikupljeni su sa sljedećih područja: Gubavica (općina Mostar) i Šehovina (grad Mostar). Pri tome su analizirana četiri uzorka: esencijalno ulje dobiveno hidrodestilacijom biljnog materijala (Gubavica), uzorak maceriran u etil acetatu (Šehovina), prikupljeni vodeni ostatak nakon hidrodestilacije (Gubavica) te komercijalno esencijalno ulje. Određivanje antioksidacijske aktivnosti uzoraka provedeno je s pomoću sljedećih metoda: DPPH, ABTS i FRAP. Hidrodestilirano esencijalno ulje, kao i komercijalno ulje, pokazali su slabiju antioksidacijsku aktivnost, što je potvrđeno svim korištenim metodama. Slabija antioksidacijska aktivnost također je zabilježena u analizi uzorka etil acetata. Praćenjem tijeka reakcije za navedene uzorke nije bilo moguće izračunati IC50 vrijednost. Vodeni ostatak nakon hidrodestilacije pokazao je najvišu antioksidacijsku aktivnost prema svim korištenim metodama, što je potvrđeno IC50 vrijednošću prema DPPH metodi, koja je bila 0,032 ± 0,006 mg/mL, dok je za ABTS metodu IC50 vrijednost bila 0,135 ± 0,003 mg/mL. Također, prema FRAP metodi, vodeni ostatak nakon hidrodestilacije pokazao je najbolju antioksidacijsku aktivnost (1099,45 ± 25,39 mg Evit. C/g ekstrakta). Usporedbom kemijskog sastava i antioksidacijske aktivnosti ispitivanih uzoraka može se zaključiti da su za antioksidacijsko djelovanje odgovorni fenolni spojevi koji su bili sadržani u vodenom ostatku nakon hidrodestilacije esencijalnog ulja, koji je i pokazao najbolju aktivnost, a da spojevi koji čine esencijalno ulje imaju neznatnu učinkovitost kad je u pitanju određivanje antioksidacijskog kapaciteta.

Poor solubility remains a critical barrier in the in vitro evaluation of phytochemicals, many of which are hydrophobic and difficult to dissolve in aqueous media. This review explores the physicochemical factors influencing phytochemical solubility, emphasizing the role of solvent properties such as polarity, proximity, and cytotoxicity. Commonly used solvents—including polar protic, polar aprotic, and non-polar solvents —are discussed concerning their solubilizing capacity and compatibility with biological systems. Solvent-induced changes in membrane dynamics and cytotoxic profiles are also examined, highlighting the need for cautious selection and optimization. Several advanced strategies to enhance solubility, such as co-solvent systems, pH modulation, nanocarrier encapsulation, surfactants, and deep eutectic solvents (DESs), are reviewed. A focused case study on curcumin illustrates how different solubilization methods can significantly improve in vitro performance. The review underscores the importance of standardized solvent reporting to ensure reproducibility and reliability in phytochemical research.

Radio frequency fingerprinting (RFF) presents a promising solution for advancing specific emitter identification (SEI) methods, which are crucial for securing the Internet of Things (IoT). While deep learning (DL)-based SEI approaches have demonstrated strong potential, they heavily depend on large, labeled datasets, which are often difficult to obtain in real-world scenarios. This reliance limits the robustness of existing SEI methods. To overcome this challenge, we propose a robust few-shot SEI (FS-SEI) method leveraging multi-view feature fusion with attention (MFFA). By integrating interpretable signal processing (SP) features with DL features and incorporating an attention mechanism for adaptive multi-view fusion, the proposed approach enhances both identification accuracy and robustness in few-shot scenarios. Experimental results validate the effectiveness of the method, showing consistent robustness under noisy conditions and significant gains in identification accuracy. These findings highlight its strong potential for practical applications in dynamic and challenging environments.

Automatic modulation classification (AMC) is a key technique for identifying the modulation schemes of wireless signals, enabling improved performance and security in communication systems by accurately classifying signal types. However, most existing AMC research assumes modulation classes are part of a closed set, which can cause classifiers to misidentify unknown modulation schemes as known ones, undermining both the security and reliability of communication systems. To address this, we propose a novel open set AMC (OS-AMC) method based on deep metric learning and OpenMax (M-OpenMax). The proposed M-OpenMax-based OS-AMC method utilizes crossentropy loss and center loss to extract separable and discriminative signal features and uses OpenMax to adjust the nonnormalized score output of the model to achieve the classification of known signals and removal of unknown signals. Experimental results demonstrate that the proposed M-OpenMax-based OSAMC method outperforms other open-set AMC techniques, particularly in its ability to handle unknown modulation types.

English has assumed the role of a global business lingua franca (BELF) at the turn of the 21st century, with an ever-increasing number of multinational corporations (MNCs) adopting English as either their official corporate language, or, the working language as a natural byproduct of a company’s linguascape. This paper investigates the use of English in a business context drawing from the BELF paradigm, i.e. it sets out to compare and contrast the frontstage and backstage English in a multinational organization in written (email) communication, as an answer to a call by Kankaanranta et al. (2018), as this specific kind of study within this genre is still underrepresented and under-researched within the Global South setting. The emails used in this study were collected from a small-sized Turkish-Bosnian international company based in B&H with a total of 10 employees. The approach adopted for the analysis of the study is discourse-analytical in its essence, supported by corpus analysis instruments. The analysis showed that the backstage English, primarily used among employees for internal communication, is indeed in most cases characterized by BELF features. Conversely, frontstage English, was shown to be aligned more closely with native English norms due to its role in corporate branding and external communication, although showing some variability as well. It is expected that the results of the study will help in understanding English communication nuances within this particular business context and help businesses foster clearer, more effective interactions across linguistic and cultural boundaries.

This study investigates the influence of specific surface area (SSA) and aluminum hydroxide particle size on sodium aluminate’s purification efficiency in the Bayer process. This research examines how variations in SSA affect the adsorption and incorporation of contaminants such as Cu, Fe, and Zn, as well as the optimal balance between effective purification and excessive Al2O3 loss. Different SSA values and purification durations are analyzed to optimize the purification process and determine conditions that maximize impurity removal while maintaining system stability. Additionally, solid residue characterization using X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS) provides insights into impurity incorporation mechanisms, including isomorphic replacement, surface adsorption, and co-crystallization. This study highlights key process parameters that influence impurity behavior and crystallization dynamics, offering valuable guidance for refining industrial purification strategies and improving aluminum hydroxide quality.

Abstract Background Humans spend up to 90% of their time indoors and are exposed to a significant number of microbes in their homes, which can have important implications for their health. Aim This study focused on analysing the influence of environmental factors on microbiome diversity and abundance in bed dust and linking the exposure to dust bacteria with asthma. Subjects and methods A total of 90 dust samples were collected from homes of asthmatic patients (n = 59) and controls (n = 31) aged 5–18 years. The bacterial fraction of the microbiome was analysed using 16S rRNA gene high-throughput sequencing on the Illumina MiSeq platform and downstream analyses in QIIME2 and R. Microbiome profiles were associated with asthma and relevant environmental and household data. Results Higher bacterial β-diversity in the environment was shown to be inversely associated with asthma (p = 0.009). Also, living environment (p = 0.002), housing type (p = 0.004), presence of pets in the household (p = 0.001), and cleaning practices (p = 0.006 for dusting and p = 0.011 for vacuuming) were prominent environmental factors affecting the bed dust microbiome. Conclusion Our results suggest significant differences in bacterial community composition between individuals with and without asthma and the interaction between indoor microbiome and asthma is mediated by environmental factors in the household.

Accurate channel estimation is critical for high-performance Orthogonal Frequency-Division Multiplexing systems such as 5G New Radio, particularly under low signal-to-noise ratio and stringent latency constraints. This letter presents HELENA, a compact deep learning model that combines a lightweight convolutional backbone with two efficient attention mechanisms: patch-wise multi-head self-attention for capturing global dependencies and a squeeze-and-excitation block for local feature refinement. Compared to CEViT, a state-of-the-art vision transformer-based estimator, HELENA reduces inference time by 45.0\% (0.175\,ms vs.\ 0.318\,ms), achieves comparable accuracy ($-16.78$\,dB vs.\ $-17.30$\,dB), and requires $8\times$ fewer parameters (0.11M vs.\ 0.88M), demonstrating its suitability for low-latency, real-time deployment.
