Visual SLAM for 3D large-scale seabed acquisition employing underwater vehicles

This paper presents a novel technique to align partial 3D reconstructions of the seabed acquired by a stereo camera mounted on an autonomous underwater vehicle. Vehicle localization and seabed mapping is performed simultaneously by means of an Extended Kalman Filter. Passive landmarks are detected on the images and characterized considering 2D and 3D features. Landmarks are re-observed while the robot is navigating and data association becomes easier but robust. Once the survey is completed, vehicle trajectory is smoothed by a Rauch-Tung-Striebel filter obtaining an even better alignment of the 3D views and yet a large-scale acquisition of the seabed

Evaluación de la vía aérea superior en pacientes con sahos mediante cefalometría 3D y multiplanar

Objetivo: determinar parámetros biométricos para evaluación y diagnóstico de pacientes con SAHOS por medio de Cefalometría Tridimensional y reconstrucción Multiplanar escanográfica. Materiales y Métodos: se realizó estudio observacional tipo cross-sectional, con 25 pacientes diagnosticados con SAHOS, a los cuales se les hizo TAC simple de cara con reconstrucción multiplanar y tridimensional, evaluando volumen de vía aérea, longitud, promedio del área en corte transversal, área retropalatal, área reglosal, espacio retrogloso lateral y anteroposterior. Resultados: se incluyeron 25 pacientes y realizaron medidas de volumen, longitud, promedio del área en corte transversal, área retropalatal, área retroglosal y espacios regloso lateral y anteroposterior, realizando análisis estadístico mediante el programa SPSS 17.0 reportando medidas de tendencia central como promedio, media, moda, rango, desviación estándar, y concordancia inter e intra observador. Conclusión: la Cefalometría tridimensional con reconstrucción multiplanar ha mostrado ser un excelente método de evaluación de vía aérea en pacientes con SAHOS, obteniendo propias clasificaciones dentro del estudio de estos pacientes. Sin embargo, ante la escasa literatura y difícil obtención de parámetros de referencia es necesario promover el estudio y la investigación de este método diagnostico en pacientes con SAHOS.

3D Analysis of the TCR/pMHCII Complex Formation in Monkeys Vaccinated with the First Peptide Inducing Sterilizing Immunity against Human Malaria

T-cell receptor gene rearrangements were studied in Aotus monkeys developing high antibody titers and sterilizing immunity against the Plasmodium falciparum malaria parasite upon vaccination with the modified synthetic peptide 24112, which was identified in the Merozoite Surface Protein 2 (MSP-2) and is known to bind to HLA-DR beta 1*0403 molecules with high capacity. Spectratyping analysis showed a preferential usage of V beta 12 and V beta 6 TCR gene families in 67% of HLA-DR beta 1*0403-like genotyped monkeys. Docking of peptide 24112 into the HLA-DR beta 1*0401-HA peptide-HA1.7TCR complex containing the VDJ rearrangements identified in fully protected monkeys showed a different structural signature compared to nonprotected monkeys. These striking results show the exquisite specificity of the TCR/pMHCII complex formation needed for inducing sterilizing immunity and provide important hints for a logical and rational methodology to develop multiepitopic, minimal subunit-based synthetic vaccines against infectious diseases, among them malaria.
