13. An Empirical Evaluation of the Local Texture Description Framework-Based Modified Local Directional Number Pattern with Various Classifiers for Face Recognition
ABSTRACT Texture is one of the chief characteristics of an image. In recent years, local texture descriptors have garnered attention among researchers in describing effective texture patterns to demarcate facial images. A feature descriptor titled Local Texture Description Framework-based Modified Local Directional Number pattern (LTDF_MLDN), capable of enco

14. TLR2 and TLR4 mediated host immune responses in major infectious diseases: a review
Abstract During the course of evolution, multicellular organisms have been orchestrated with an efficient and versatile immune system to counteract diverse group of pathogenic organisms. Pathogen recognition is considered as the most critical step behind eliciting adequate immune response during an infection. Hitherto Toll-like receptors (TLRs), especially t

15. Seasonal and circadian variation of the sexual behavior of Morada Nova rams in tropical environment
The objective of this study was to evaluate the seasonal and daily variation in sexual behavior of Morada Nova breeders raised in the Brazilian semi-arid region. The data were collected from four rams and 114 ewes of the Morada Nova breed - 55 females in the dry season and another 59 in the rainy season. Observations were performed in the dry and rainy seaso

16. Automatic pain quantification using autonomic parameters
The objective measurement of subjective, multi-dimensionally experienced pain is a problem for which there has not been an adequate solution. Although verbal methods (e.g., pain scales and questionnaires) are commonly used to measure clinical pain, they tend to lack objectivity, reliability, or validity when applied to mentally impaired individuals. Biopoten

17. Flexibilidad en la resolución de problemas de identificación de patrones lineales en estudiantes de educación secundaria
The aim of this study is to characterize the flexibility of secondary school students (12-16 years old) in problems that involve the recognition of patterns. Flexibility is understood as the ability to modify the strategy used in solving a problem when the cognitive demand of the task is changed. The methodology used is qualitative analyzing students' answer

18. Study on the population structure of the paradoxical frog, Pseudis bolbodactyla (Amphibia: Anura: Hylidae), using natural markings for individual identification
The goal of this study was to assess the population structure of Pseudis bolbodactyla Lutz, 1925 using natural markings to identify individuals. Recruitment, survival, and population size estimations were obtained using the Jolly-Seber stochastic method. A total of 166 individuals were captured, and the striped, spotted, and dotted patterns that make their r

19. Right cerebral hemisphere and central auditory processing in children with developmental dyslexia
Objective We hypothesized that if the right hemisphere auditory processing abilities can be altered in children with developmental dyslexia (DD), we can detect dysfunction using specific tests. Method We performed an analytical comparative cross-sectional study. We studied 20 right-handed children with DD and 20 healthy right-handed control subjects (CS).
