Exploring the value of thematic urban ecosystem accounts in Western Balkan countries to inform urban greening actions

Urban ecological health is increasingly prioritised in Europe, as reflected in the EU Biodiversity Strategy 2030, the Nature Restoration Regulation, and the amended Regulation on Environmental-Economic Accounts. Translating these commitments into effective greening policy and pla...

АНГЛОРУСКИ И АНГЛОСРПСКИ: ОДРАЗ БУДУЋНОСТИ У ЛЕКСИЧКИМ СИСТЕМИМА РУСКОГ И СРПСКОГ ЈЕЗИКА

Утицај страних језика, у првом реду енглеског, на друге језичке системе акту елно је и важно лингвистичко питање. Англоглобализација, како се неретко назива ова појава, огледа се у преузимању великог броја речи из енглеског језика чиме се доприно си ширењу хибридног ‘језика’. Сав...

Selection of Dental Implant Biomaterial by Using a Developed MCDM Solver

A proper selection of materials, especially biomaterials, ensures a reliable and long-lasting working life of the component, i.e., implant. The selection of materials for the manufacture of dental implants represents a significant challenge when it comes to the choice of biomater...

Cognitive impairment and danger to humanity, or personal assistant and learning tool? Exploring attitudes towards ChatGPT and their predictors

This study examines the factors shaping attitudes towards ChatGPT inclusive of personality traits, ideological orientations, AI literacy, gender, and cultural context. In Study 1 ( N total = 500; N valid = 472 Serbia), positive perceptions of ChatGPT as a learning tool and person...

The robotic PIANO: a critical narrative review of surgeon-controlled operative polyphony, human factors, and robotic training

Abstract Robotic surgery can concentrate control of several technical functions at the console, but such concentration does not itself confer clinical independence, reduce dependence on the perioperative team, or improve patient outcomes. We define surgeon-controlled operative po...

Corvis ST Assessment of Corneal Biomechanical Properties in Patients with Type 2 Diabetes Mellitus

Background and Objectives: Diabetes mellitus (DM) is associated with structural and biochemical changes in the cornea that may influence its biomechanical behavior. This study aimed to compare corneal biomechanical properties between healthy individuals and patients with type 2 D...

A polynomial GCD certificate for exact flat bands in finite-range Bloch Hamiltonians

Abstract We formulate a polynomial GCD certificate for exact flat bands in finite-range periodic tight-binding Hamiltonians. Writing the characteristic polynomial of the Bloch Hamiltonian as a Laurent polynomial P_L(z, λ) = det(λI-H_B(z)) = sum_t c_t(λ) z^t , we show that the mon...

OBJECTIVE: The aim of this retrospective study is to analyze the outcome and survival of patients with well-differentiated metastatic neuroendocrine neoplasm (NEN) treated with peptide receptor radionuclide therapy (PRRT). SUBJECTS AND METHODS: Y-DOTA-TOC in 2 (6%) patients. No a...

Waste management performance in the Western Balkans: A multi-criteria assessment using the PROMETHEE method

Solid waste management in the Western Balkans remains critically underdeveloped relative to European Union (EU) standards, with recycling infrastructure gaps, widespread reliance on landfilling, and incomplete harmonisation with the EU Waste Framework Directive posing persistent...

A weak $m$-WGI for rectangular matrices

Inspired by significant results regarding the $m$-weak group inverse ($m$-WGI) and its generalization to rectangular matrices, known as the $W$-weighted $m$-WGI ($W$-$m$-WGI), we investigate the solvability of a new and more general matrix equations that extend those previously u...

Automated In-InjectorPort Conversion of AristolochicAcids to Aristolic Acids for Enhanced HPLC Fluorescence Detection

Abstract Aristolochic acids (AAs) and the herbs containing them are recognized human carcinogens. Emerging evidence indicates that AAs are also food and environmental contaminants, posing significant risks to human health. This study developed a highly sensitive AA detection meth...

Integrated Chemical, Computational, and Cellular Profiling of a Dual-Oil Melanoma Formulation: An Exploratory Life-Science Study

Background: Previous studies have examined bioactive constituents of Prunus dulcis oil, Pinus sylvestris essential oil, and related phytochemical matrices separately; however, their combined chemical profile, comparator-context molecular-docking landscape, and comparative cellula...

The Institutional Plateau in Microcredential Adoption: A Hybrid Review of Peer-Reviewed Evidence and Practitioner Reports in Higher Education

Micro-credentials have attracted intense scholarly and policy attention, yet recent practitioner evidence, most notably the 2026 UPCEA survey of US institutions, the catalyst for this review, suggests that institutional commitment has plateaued even as individual engagement deepe...

Association Between the Presence of Multimorbidity and Sociodemographic Factors and Health Care Utilization in the Adult Population of Serbia: A National Health Survey

Introduction: Multimorbidity, defined as the coexistence of two or more chronic conditions in the same person, represents a major challenge for modern health systems due to its association with adverse health outcomes, increased mortality, and high healthcare utilization. We aime...

Potentially Clinically Relevant Drug–Drug Interactions in Oncology Patients Receiving Chronic Opioid Therapy: Prevalence and Associated Factors

Background: Patients with malignant diseases receiving chronic opioid therapy are particularly susceptible to drug–drug interactions because of extensive polypharmacy, multimodal anticancer treatment, supportive care, and comorbidities. This study aimed to determine the prevalenc...
