Mesoporous PU/PEDOT:PSS Electrodes Reveal Population‐Level Stochastic Bioelectrical Dynamics in Marine Diatoms

ABSTRACT Understanding how microbial populations generate and modulate electrical signals remains a major technical challenge because extracellular ionic processes are inherently weak, spatially distributed and stochastic. Here, we introduce a mesoporous ultra‐low‐impedance PEDOT...

Advancing project studies under the design science paradigm

Purpose This paper examines how the design science paradigm has been incorporated and progressively consolidated within Project Studies, and how this trajectory can inform future research. It analyses publication patterns, intellectual configuration, artefact types, problem class...

Luminescence dating of offshore tsunami deposits from the Shetland Islands, United Kingdom

Abstract. With onshore geological evidence of three tsunami events, the Shetland Islands (UK) yield the most-detailed Holocene tsunami record in the North Sea region. Lately, tsunami deposits were also identified in shallow waters offshore the Shetland Islands. These offshore tsu...

Noise Pollution in Urban Environments: The Moderating Role of Housing Conditions on Indoor Noise Perception

Contemporary urban environments are characterized by intense and continuous activity, resulting in a significant transformation of the ambient acoustic environment. Noise pollution from sources such as traffic, construction, industry, and recreation propagate throughout these are...

Building trait complexes of individual differences: A study with higher education students

Interactions among the cross-domain variables of interests, personality, and perceived abilities were analyzed in a higher education sample (N = 312) from a Portuguese public University consisting of 48.9% female and 51.1% male students, aged between 18 and 30 years, and enrolled...

Architectural traits constrain the evolution of unisexual flowers and sexual segregation within inflorescences: an interspecific approach

ABSTRACT Male and female unisexual flowers have repeatedly evolved from the ancestral bisexual flowers in different lineages of flowering plants. This sex specialization in different flowers often occurs within inflorescences. We hypothesize that inflorescence architecture may im...

Autistic neural ‘shiftability’: the distinct pharmacological landscape of the autistic brain

Functionally inter-connected large-scale brain networks regulated by multiple neurotransmitter systems underpin complex human behaviour. A wide range of alterations in this neurofunctional landscape have been associated with autism. However, this evidence is mostly derived from c...

Overview of the re‐evaluation of trace elements as nutritional feed additives in the European Union : characterization, safety, and efficacy

The re-evaluation of feed additives in the European Union was outlined in the Regulation (EC) No 1831/2003. The primary objectives were to ensure safety and verify efficacy, as well as to update authorizations and phase out unsafe additives or those in which the industry expresse...

Quality of life and social relationships in people with aphasia: a cross-sectional study

Background Aphasia is a chronic acquired communication disorder that may change the lives of those who live with it. Although its impact on Quality of Life (QOL) is acknowledged, people with aphasia (PWA) remain underrepresented in QOL research. Furthermore, since QOL correlates...

A knowledge-based decision support framework for multi-hazard and cascading NaTech risk assessment: Systematic review and multi-criteria evaluation

Integrating declarative hazard taxonomies, procedural cascade logic, and heuristic expert elicitation within a unified inference architecture represents a foundational challenge in knowledge-based systems (KBS) design for operational risk management. This paper addresses this cha...

Environmental drivers of litter- and soil-dwelling springtail communities across European forests, assessed by morphotaxonomy and soil DNA metabarcoding

Springtails are abundant in forest litter and soils, where they play a crucial role in the transformation and decomposition of organic matter. However, most data on springtail communities originates from studies at the local and regional levels, while larger-scale studies are lac...

Dense and Cold Magnetized Quark Matter: A Review of Magnetic-Field-Independent Regularization and the Medium Separation Scheme

We present a comprehensive review of regularization schemes for magnetized dense quark matter within effective models of quantum chromodynamics, focusing on the Magnetic-Field-Independent Regularization (MFIR) and the Medium Separation Scheme (MSS) at finite chemical potential an...

The Potential of N ‐Benzyl Spiro‐Oxindole Hydantoins as Antileishmanial Agents Against Leishmania infantum

ABSTRACT Leishmaniasis, caused by protozoa of the genus Leishmania remains a significant public health concern due to the high lethality of the visceral form if untreated. Current therapies have important limitations, including toxicity and the availability of only a single appro...

Tax Litigation and Characteristics of Audit Opinions: Implications for Transparency and Trust in B3

Purpose. This study investigates how tax litigation affects the length, tone, clarity, and complexity of audit opinions for companies listed on Brazil’s B3 exchange, and the implications for financial reporting transparency and trust. Design/methodology/approach. A fixed-effects...

Myeloma Elderly Prognostic Score ( MEPS ): A Proposed Prognostic Score Integrating Age, Renal Function, Performance Status, and Ultra‐High‐Risk Cytogenetics

Established disease-centered prognostic systems may be less tailored to elderly/non-transplant-eligible (NTE) patients with multiple myeloma (MM), in whom host-related factors such as age, performance status, and renal function strongly influence all-cause outcomes. We developed...

A multi-dimensional framework for measuring urban inclusiveness and crime using mobility traces: A socio-spatial study of Lisbon

Urban inclusiveness and safety are shaped by daily interactions between residents, visitors, and the built environment. Capturing these socio-spatial dynamics requires fine-grained data beyond traditional census or survey-based approaches. This study proposes an analytical framew...

Gut microbiome seasonality is associated with dietary plasticity and coexistence in three sympatric Pamir ungulates

This graphical abstract outlines a multi-omics framework investigating the seasonal dietary composition and gut microbial communities of three coexisting ungulate species inhabiting the extreme high-altitude Pamir Plateau (Ovis ammon polii, Capra sibirica, and Pseudois nayaur). B...

Challenges for a sustainable blue economy: A comparative analysis of resilience and coastal governance in Southern Europe

Coastal blue economies face intensifying pressures from climate change, biodiversity loss and systemic uncertainty, making resilience a central concept in coastal governance. This article advances a socio-ecological-technological (SET) system framework to analyse how resilience i...

Radium - from discovery to the present day – narrative review

Following its discovery, radium was initially promoted as a therapeutic agent for a wide range of conditions, including skin disorders, allergies, visual problems, joint pain, and as a general health-enhancing remedy. However, subsequent research demonstrated its significant radi...
