SNeL: A Structured Neuro-Symbolic Language for Entity-Based Multimodal Scene Understanding
In the evolving landscape of artificial intelligence, multimodal and
Neuro-Symbolic paradigms stand at the forefront, with a particular emphasis on
the identification and interaction with entities and their relations across
diverse modalities. Addressing the need for complex querying and interaction in
this context, we introduce SNeL (Structured Neuro-symbolic Language), a
versatile query language designed to facilitate nuanced interactions with
neural networks processing multimodal data. SNeL's expressive interface enables
the construction of intricate queries, supporting logical and arithmetic
operators, comparators, nesting, and more. This allows users to target specific
entities, specify their properties, and limit results, thereby efficiently
extracting information from a scene. By aligning high-level symbolic reasoning
with low-level neural processing, SNeL effectively bridges the Neuro-Symbolic
divide. The language's versatility extends to a variety of data types,
including images, audio, and text, making it a powerful tool for multimodal
scene understanding. Our evaluations demonstrate SNeL's potential to reshape
the way we interact with complex neural networks, underscoring its efficacy in
driving targeted information extraction and facilitating a deeper understanding
of the rich semantics encapsulated in multimodal AI models
Organizing a Society of Language Models: Structures and Mechanisms for Enhanced Collective Intelligence
Recent developments in Large Language Models (LLMs) have significantly
expanded their applications across various domains. However, the effectiveness
of LLMs is often constrained when operating individually in complex
environments. This paper introduces a transformative approach by organizing
LLMs into community-based structures, aimed at enhancing their collective
intelligence and problem-solving capabilities. We investigate different
organizational models-hierarchical, flat, dynamic, and federated-each
presenting unique benefits and challenges for collaborative AI systems. Within
these structured communities, LLMs are designed to specialize in distinct
cognitive tasks, employ advanced interaction mechanisms such as direct
communication, voting systems, and market-based approaches, and dynamically
adjust their governance structures to meet changing demands. The implementation
of such communities holds substantial promise for improve problem-solving
capabilities in AI, prompting an in-depth examination of their ethical
considerations, management strategies, and scalability potential. This position
paper seeks to lay the groundwork for future research, advocating a paradigm
shift from isolated to synergistic operational frameworks in AI research and
application

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/).The therapeutic landscape of metastatic castration-resistant prostate cancer (mCRPC) has substantially evolved over the last decade. Nonetheless, a better understanding of bone-targeted agents (BTAs) action in mCRPC remains an unmet need. Theuse of BTAs aims to reduce the incidence of skeletal-related events (SREs) in patients with mCRPC. Less frequent BTA schedules are currently being studied to minimize adverse events. In this study, the impact of metastatic compartment (bone and extraskeletal metastases (BESM) vs. bone-only metastases (BOM)) on bone biomarker kinetics, time to first on-study SRE, and symptomatic skeletal events (SSEs) is evaluated. This is a retrospective analysis of the prospective, randomized, multicenter clinical trial of denosumab vs. zoledronic acid in patients with mCRPC and bone metastases. A total of 1901 patients were included, 1559 (82.0%) with BOM and 342 with BESM (18.0%). Bone metastases burden was balanced between groups. Baseline levels and normalization rates of corrected urinary N-terminal telopeptide and bone alkaline phosphatase did not differ between groups. However, BESM patients had a higher risk of SREs (adjusted HR 1.21; 95% CI 1.01-1.46; p = 0.043) and SSEs (adjusted HR 1.30; 95% CI 1.06-1.61; p = 0.014). This difference was more pronounced in the first 12 months of BTA treatment.In mCRPC, strategies of BTA schedule de-escalation may take into account presence of extraskeletal metastases.info:eu-repo/semantics/publishedVersio
Ranking contrasting genotypes of forage peanut based on nutritive value and fermentation kinetics
AbstractThe objective of this study was to evaluate the nutritional divergence of perennial peanut genotypes through chemical characteristics as well as in vitro fermentation and degradation kinetics. The experiment was conducted at The Brazilian Agricultural Research Corporation (Embrapa Cerrados). The treatments consisted of 10 accessions of Arachis spp., 6 accessions of A. pintoi (Ap 8, Ap 19, Ap 20, Ap 24, Ap 31, Ap 65) and the cultivar Belmonte, 2 accessions of Arachis repens (Ar 5, Ar 26) and an interspecific hybrid (Ap×Ar) 9. The experimental design was a completely randomised block with four replications. Forage evaluations were made at a stubble height of 5cm from the soil surface with fixed cutting intervals of 42 days during the rainy season. Nutritional divergence was assessed using canonical variate analysis and hierarchical agglomerative clustering including the variables crude protein, neutral detergent fibre, lignin(sa), potential DM degradation at 48h, the insoluble but potentially degradable DM fraction and the degradation rate of the insoluble but potentially degradable DM fraction. Variables with higher contribution to discrimination of accessions were: rate of degradation, crude protein and potential DM degradation at 48h. Four distinct nutritional groups were identified: Group I (Ap 8, Ap 19, Ap 31, cv. Belmonte), Group II (Ap 20, Ap 24, Ap 65), Group III (Ar 5. Ar 26) and Ggroup IV (Ap×Ar 9). The nutritional divergence of the Arachis evaluated show great variability relative to the parameters analysed, which may impact genetic improvement programs which focus on chemical composition and in vitro fermentation characteristics. Group IV (hybrid Ap×Ar 9) had the highest nutritional quality as ruminant feeds
Tumores de células granulares na língua: relato de 2 casos
ResumoO tumor de células granulares é uma neoplasia benigna incomum com forte predileção pela cavidade oral, com um maior número de casos afetando a região da língua. Apresenta-se geralmente como um nódulo solitário, assintomático, de base séssil, com crescimento lento (meses ou anos) e coloração variável. Apesar da sua etiologia incerta, há estudos que apontam para uma origem neural para a lesão. O presente artigo tem como objetivo apresentar 2 casos clínicos cuja queixa principal era um nódulo submucoso no dorso da língua, com evolução lenta e superfície epitelial hígida. Em ambos os casos, o diagnóstico definitivo foi realizado após a análise histológica e imuno-histoquímica e o tratamento realizado através de excisão cirúrgica conservadora. Também são discutidos os aspetos clínicos, histológicos e imuno-histoquímicos do tumor de células granulares.AbstractThe granular cell tumor is an uncommon benign neoplasm with a strong predilection for the oral cavity, with a greater number of cases affecting the tongue. It typically presents as a solitary nodule, asymptomatic, sessile base, with slow growth (months or years) and variable color. Despite its uncertain etiology, studies suggest a neural origin for the lesion. The aim of this article is to present two clinical cases whose main complaint was a submucosal nodules in the dorsum of the tongue, with slow evolution and healthy surface. In both cases, definitive diagnosis was made after histological and immunohistochemical analysis and the treatment was made with conservative surgical excision. It is also discussed clinical, histological and immunohistochemical features of granular cell tumor
Racial disparity and prognosis in patients with mouth and oropharynx cancer in Brazil
Oral and oropharyngeal cancer (OPC) is an important cause of morbidity and mortality worldwide. Populations in situations of social vulnerability tend to have higher incidences of cancer, a higher proportion of late diagnosis, greater difficulties in accessing health services, and, consequently, worse prognosis. The aim of this study was to evaluate the relationship between race/skin color and OPC prognosis in Brazil. This is a cross-sectional epidemiological study using OPC data from the National Cancer Institute between the years 2000 and 2019. The selected variables were: gender, race/skin color, age, education, smoking and alcohol consumption, stage of the disease and disease status at the end of the 1st treatment. 154,214 cases were recorded. Black men, in the 6th decade of life, were the most affected population. Blacks had a lower level of education when compared to non-blacks (p<0.001). Blacks were more exposed to smoking and alcohol consumption (p<0.001). At the time of diagnosis, the black population was at the most advanced stage when compared to non-blacks (p<0.001). At the end of the 1st treatment, more black patients had disease in progression, as well as more black patients died (p<0.001). Blacks had a worse prognosis for OPC in Brazil. Despite the limitations, these results are important to elucidate the scenario of health disparities in relation to the race/skin color of the Brazilian population

High prevalence of oral potentially malignant disorders and risk factors in a semi-urban brazilian city:a population-based cross-sectional study
Oral Potentially Malignant Disorders (OPMDs) are defined as lesions with a greater likelihood of progressing to cancer. Population-based studies that evaluate the prevalence of OPMDs are scarce in Brazil. The aim of the present study was to determine the prevalence of OPMDs and associated risk factors in a semi-urban Brazilian population. This is a cross-sectional study, whose universe included individuals aged 40 years or older residing in a medium-sized city of northeastern Brazil. Data collection was divided into two steps: interview and oral examination. The outcome variable was the presence of OPMDs. The predictor variables were sociodemographic characteristics and risk habits. The bivariate analysis was performed through chi-square test. The crude prevalence ratios (PR) and its respective 95% confidence intervals (CI) were calculated. Poisson regression analysis with robust variance was used to calculate adjusted PRs and 95% CI. Three hundred fourteen individuals were included in the study. When asked about risk habits, 58.9% reported being current smokers or ex-smokers and 62.2% reported being current drinkers or ex-drinkers. The prevalence of OPMDs was 7.6% and was significantly higher among individuals with black skin color (p < 0.001), alcohol users (p = 0.017), and individuals with both tobacco and alcohol habits (p = 0.012). Therefore, the population in the present study had a high frequency of risk habits associated with PMDs of the oral cavity
