1. Predictive model for difficult laryngoscopy using machine learning: retrospective cohort study
Abstract Background Both predictions and predictors of difficult laryngoscopy are controversial. Machine learning is an excellent alternative method for predicting difficult laryngoscopy. This study aimed to develop and validate practical predictive models for difficult laryngoscopy through machine learning. Methods Variables for the prediction of difficul

2. PREVALENCE OF INJURIES IN BRAZILIAN RECREATIONAL STREET RUNNERS: META-ANALYSIS
RESUMO A corrida de rua é uma forma de exercício acessível e de baixo custo. No entanto, a ocorrência de lesões musculoesqueléticas pode dificultar a prática regular. O objetivo deste estudo foi estimar a prevalência de lesões em corredores de rua brasileiros e os fatores associados. Foi realizada uma metanálise de estudos brasileiros para investig

3. Calculation of Aircraft Target's Single-Pulse Detection Probability
ABSTRACT: The original radar cross section data or some rough models are often used to estimate a given aircraft target detection probability. The calculation results may not be very accurate as targets are different from one another and the real radar detection process is complex. A new method for radar cross section model generation is proposed and it take

4. Influence of slab length on dynamic characteristics of subway train-steel spring floating slab track-tunnel coupled system
A subway train-steel spring floating slab track-tunnel coupling dynamic model, considering short and middle-long wavelength random track irregularities, and longitudinal connection between adjacent slabs of steel spring floating slab track, was developed. And the influence of slab length on dynamic characteristics of the system under different track conditio

5. Multifocal versus monofocal intraocular lenses after cataract extraction
BACKGROUND: Good unaided distance visual acuity is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision, however, still requires additional refractive power, usually in the form of reading gla

6. Phylogeny, biogeography and divergence times in Passiflora (Passifloraceae)
As part of a long-term investigation on the evolution of Passiflora L., we investigated the divergence ages of the genus and diversification of its subgenera, relating them with biogeographical and/or historical events, and other characteristics of this taxon. The main aim of the present work was to evaluate the biogeographic distribution of this genus to be

7. Concentração de triptofano e variáveis cinemáticas a diferentes percentuais da velocidade crítica no nado crawl
The aim of this study was to investigate the changes in plasma tryptophan concentration ([TRP]) and kinematic variables in a series of interval training in different percentages of the critical speed (CS) in front crawl. Volunteers were 14 competitive male swimmers with at least four years experience in this style and swimming 48 ± 11 km per week. The subje

8. Indices of movement behaviour: conceptual background, effects of scale and location errors
A fundamental step in the emerging Movement Theory is the description of movement paths, and the identification of its proximate and ultimate drivers. The most common characteristic used to describe and analyze movement paths is its tortuosity, and a variety of tortuosity indices have been proposed in different theoretical or empirical contexts. Here we revi

9. Deterministic partially self-avoiding walks: analytical results for the effect of tourists memory in the exploration of disordered media / Caminhadas deterministas parcialmente auto-repulsivas: resultados analíticos para o efeito da memória do turista na exploração de meios desordenados
Considere um meio desordenado constituído por $N$ pontos cujas coordenadas são geradas aleatoriamente de maneira uniforme e independente nas arestas unitárias de um hipercubo $d$-dimensional. As probabilidades de vizinhança entre os pares de pontos deste meio são expressas através da fórmula de Cox. Um caminhante parte de um dado ponto deste meio deso

10. Geostatistics in the sequential sampling plan of leaf-cutting ant nests in eucalyptus plantations in the Atlantic forest region / GeoestatÃstica na amostragem sequencial de ninhos de formigas cortadeiras em eucaliptais em regiÃo de mata atlÃntica
One of the basic steps of the integrated pest management is the evaluation of pest population. For this, it is necessary to know how it is distributed on the field. Regarding the leaf-cutting ants, several studies have been developed to investigate their distribution as well as how to sample them adequately, but it is also necessary to improve such studies w

12. Estimativas de funÃÃes de covariÃncia para caracterÃsticas de crescimento da raÃa tabapuà utilizando modelo de regressÃo aleatÃria / Estimates of service for covariÃncia characteristics of growth of race tabapuà using model regressÃo random
The study used 28,873 weight records taken along the life of 6.471 animals of the race TabapuÃ, finery birth to 660 days of age, belonging to the animal archives of the Brazilian Association of Zebu Breeders (ABCZ) to estimate the covariÃnce functions using the models of random regression. The genetic, addictive direct an permanent environmental effects we
