1. Damped Jacobi Methods Based on Two Different Matrices for Signal Detection in Massive MIMO Uplink
Abstract For massive multiple-input multiple-output (m-MIMO) uplink, the performances of the linear minimum mean-square error (MMSE) detector are considered near optimal, and they occupy benchmark place for most linear iterative detectors. However, the MMSE algorithm is known by its load computational complexity due to the implication of large-scale matrix i

3. Hearing Assessment of Neonates at Risk for Hearing Loss at a Hearing Health High Complexity Service: An Electrophysiological Assessment
Abstract Introduction Hearing is the main sensory access in the first years of life. Therefore, early detection and intervention of hearing impairment must begin before the first year of age. Objective To analyze the results of the electrophysiological hearing assessment of children at risk for hearing loss as part of the newborn hearing screening (NHS).

6. A meta-analysis over geometric modeling simplifications in ENVI-met urban climate simulation
Resumo A modelagem do clima urbano requer a descrição da geometria do ambiente construído, entretanto a complexidade do tecido urbano traz incertezas sobre o formato e localização exata das edificações. Portanto, durante o processo de planejamento, modelos de geometria simplificada podem ser mais apropriados que modelos detalhados. Nessa pesquisa foi

7. Power Allocation in PON-OCDMA with Improved Chaos Particle Swarm Optimization
Abstract In this work, it is investigated an improved chaos particle swarm optimization (IC-PSO) scheme to refine the quality of the algorithm solutions regarding to solve the optimal power allocation in next generation passive optical networks (NG-PON)s. The proposed IC-PSO scheme utilizes the Beta distribution instead of uniform distribution of the traditi

8. Reappraising the dimensional structure of the PTSD Checklist: lessons from the DSM-IV-based PCL-C
Objective: The dimensional structure of posttraumatic stress disorder (PTSD) has been extensively debated, but the literature is still inconclusive and contains gaps that require attention. This article sheds light on hitherto unvisited methodological issues, reappraising several key models advanced for the DSM-IV-based civilian version of the PTSD Checklis

9. Brain Region Specificity of Mitochondrial Biogenesis and Bioenergetics Response to Nrf2 Knockdown: A Comparison Among Hippocampus, Prefrontal Cortex and Amygdala of Male Rat Brain
ABSTRACT Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) has been identified as the well-known coordinator of intracellular antioxidant defense system. Herein, we aimed to evaluate the effects of Nrf2 silencing on mitochondrial biogenesis markers peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), nuclear respiratory factor-1(N

10. Pedological Heterogeneity of Soils Developed from Lithologies of the Pirambóia, Sanga-do-Cabral, and Guará Geological Formations in Southern Brazil
ABSTRACT The source material is one of the factors that most influence soil genesis and the mainly responsible for the nature, composition, and behavior of the soil. Given the geological complexity of the Santa Maria River basin, the objective of this study was to investigate whether the new lithologies described recently may be responsible for a greater var

12. Development of the Arithmetic Subtest of the School Achievement Test-Second Edition
Abstract The School Achievement Test (Teste de Desempenho Escolar, TDE) has been widely used in clinical and educational contexts for the past 22 years. Arithmetic disorders are frequent among children and teenagers, requiring new and updated tasks to assess as accurately as possible school achievement. The last decade has witnessed a growing recognition of
