In the present work, the Ã2Πu→ X̃2Πg (Fox-Duffendack-Barker) electronic transition of the CO2+ molecular ion has been investigated using high-resolution Fourier transform emission spectroscopy in the 20,000 – 33,000 cm−1 range. A total of 62 bandheads were assigned and rotationally analysed, including 17 subbands subjected to detailed rotational analysis for the first time. This investigation allowed the determination of spectroscopic constants for the 102, 202, 302 and 402 levels of the X̃2Πg ground state, reported here for the first time. Precise wavenumber measurements produced improved molecular constants and band origins, establishing more reliable parameters than those previously available in the literature. Based on this refinement, a comprehensive set of spin-vibronic term values was derived and validated by comparing it with previous results available in the literature.
This paper explores the role of the seven constructs—Digitalization, Entrepreneurial Orientation, Funding, Governance, Managerial Capabilities, Market Configuration, and Performance—towards SME sophistication and managerial performance in Brazil. Based on a survey conducted among Brazilian SME managers, focusing on seven key constructs—Digitalization, Entrepreneurial Orientation, Funding, Governance, Managerial Capabilities, Market Configuration, and Performance, a novel entropy maximization approach based on neutrosophy, fuzzy logic, and gray relational analysis was designed to retrieve information on perceptual Likert scales so as distinct construct indexes could be built. Subsequently, a robust MCDM approach was implemented on the sophistication scales of each construct to identify the key drivers within and between superior SME construct indexes towards improved managerial performance. The study found that funding, governance, entrepreneurial orientation, and digitalization are major factors contributing to SME sophistication in Brazil. Additionally, managerial capabilities and market configuration were identified as critical for supporting and enhancing managerial performance and competitiveness. This suggests that a combination of strong internal management practices, strategic governance, and access to funding and digital resources plays a central role in SME growth and performance. These insights underscore the importance of comprehensive resource management and organizational adaptability for Brazilian SMEs aiming to enhance their operational effectiveness and market positioning.
Environmental pollution research has expanded rapidly over recent decades, resulting in a fragmented body of scientific knowledge. This study provides a bibliometric synthesis of global pollution research between 1985 and 2024, based on 1,447 Scopus-indexed publications, treating review and bibliometric articles as analytical units to examine the structure, thematic organization, and geographic distribution of the field. Publication dynamics, citation patterns, collaboration networks, keyword co-occurrence, and temporal metrics were combined to identify priorities and patterns. Results reveal an exponential increase in review-based scientific output since the mid-2010s, reflecting a growing demand for synthesis-oriented research. China, India, and Brazil together account for more than 40
To investigate the otorhinolaryngological manifestations associated with Autism Spectrum Disorder (ASD), exploring how dysfunctions in sleep, hearing, smell, and taste may act as relevant sensory and clinical markers. This review also aims to contextualize these findings within a sensory integration framework and to discuss their clinical relevance beyond isolated peripheral alterations. Recent studies indicate a high prevalence of sleep disturbances (50–80
The complex geometry of biphenylene materials offers alternative routes for exploring novel stacking configurations achieved by piling up carbon-thin sheets. Here we investigate sliding-induced topological transitions in biphenylene bilayers, proposing various novel stacking configurations. They are analyzed from a symmetry perspective and described in detail, highlighting the intricate patterns of type-II Dirac cone crossings. Topological changes in the Fermi surface are assessed via the Euler characteristic, linking each transition to its corresponding symmetry, which can be experimentally tested by conductance measurements. Moreover, the ability to tune these topological properties by sliding the layers provides a simpler and more effective way to observe such phenomena.
