Ground states and periodic-to-localized convergence in two-dimensional saturable discrete nonlinear Schrödinger equations

We study a two-dimensional discrete nonlinear Schrödinger equation with saturable nonlinearity on the lattice Z2. Using a variational approach based on the Nehari manifold, we establish the existence of nontrivial periodic ground states on finite lattices and establish the existe...

How Everyday Microplastics Quietly Rewire Nickel Availability in Mediterranean Calcareous Soils

Microplastics are emerging as ubiquitous contaminants in agricultural soils, while nickel (Ni), although catalogued as a potentially toxic element, is an essential micronutrient and a cofactor of urease. In a pot experiment, this study examined how three microplastics (polyethyle...

Long-term population dynamics of a human-associated colonial raptor: Case of Lesser Kestrel Falco naumanni

Long-term monitoring is essential for understanding how demographic processes operating across generations, and under environmental stochasticity, shape population change. This is especially true in human-modified landscapes where nesting opportunities and food resources can shif...

Neuroimaging findings of the hypothalamus and pituitary gland in children with growth hormone deficiency: a 25-year single-center retrospective study

Abstract Purpose Growth hormone deficiency (GHD) is a cause of short stature in childhood. Central nervous system imaging, including hypothalamic-pituitary magnetic resonance imaging (MRI) is important for the diagnostic investigation of these patients. The aim of this descriptiv...

Intelligent Environments in Manufacturing Ecosystems: Improving Innovation Performance Through Digital Platforms and Connected Intelligence

Manufacturing sectors and ecosystems can improve their innovation performance through digital platforms, connected intelligence, and organisational settings that enable collaboration among experts and ecosystem members. The convergence of skills and capabilities distributed acros...

BMAL1-Mediated Circadian Regulation of Oocyte Quality and IVF Outcomes

Successful embryo development transpires far before fertilization inside the meticulously regulated microenvironment of the ovarian follicle. Increasing data indicates that circadian regulatory systems influence several processes that define oocyte competence, including mitochond...

School Principals' Perspectives on Individual Teacher Evaluation in Greek Primary Education: Implications for Educational Innovation and Quality Enhancement

Abstract : The implementation of individual teacher evaluation under Law 4823/2021 has reintroduced teacher appraisal as a key educational policy issue in Greece, assigning school principals a central role in its implementation. This study investigated primary school principals’...

Health needs assessment of women with spinal cord injury in Greece: a qualitative study

Women with spinal cord injuries (SCI) are a group with multiple unmet health needs, typically neglected in research and policy development. This study employs a participatory design approach. Three focus groups for in-depth, qualitative interviews were conducted to explore the he...

Patterns and phenotypes of enhanced recovery after surgery implementation in gynaecological oncology: A latent class analysis

Objective: Enhanced recovery after surgery protocols are widely recommended, yet their real-world implementation remains inconsistent due to multiple barriers. This study aimed to characterise implementation patterns during early enhanced recovery after surgery adoption. Methods:...

Exosome-Based Therapeutics in Alzheimer’s Disease: Translational Perspectives Beyond Conventional Therapies

Alzheimer’s disease (AD) remains a major neurodegenerative disorder lacking effective long-term disease-modifying therapies. Current pharmacological approaches provide primarily symptomatic benefit, while recently approved anti-amyloid monoclonal antibodies offer only modest clin...

Low-dose atropine-related esotropia in a myopic child: a case report

AIMS/PURPOSE: Acute-onset strabismus in highly myopic children raises a broad differential diagnosis. In this article, we report a pediatric case with high myopia and prolonged near focus who presented concomitant esotropia during treatment with atropine 0.05% eye drops. METHODS:...

Hypoplastic lateral rectus muscle in a 39-year-old female with esotropia

PURPOSE: Congenital hypoplasia of the extraocular muscles is a rare cause of strabismus. This article aims to report the case of a 39-year-old female with esotropia and a hypoplastic lateral rectus muscle (LRM). METHODS: Case report. RESULTS: The patient presented with esotropia...
