Perception, Positioning and Decision-Making Algorithms Adaptation for an Autonomous Valet Parking System Based on Infrastructure Reference Points Using One Single LiDAR.

Autonomous parking valet systems improve users' comfort, helping with the task of searching for a parking space and parking maneuvering; and due to the simple infrastructure design and low speeds, this maneuver is quite feasible for automated vehicles. Various demonstrations have been performed in both closed parking and in open air parking; scenarios that allow the use of specific technological tools for navigation and searching for a parking space. However, there are still challenges. The purpose of this paper was the integration of perception, positioning, decision-making, and maneuvering algorithms for the control of an autonomous vehicle in a parking lot with the support of a single LiDAR sensor, and with no additional sensors in the infrastructure. Based on a digital map, which was as simplified as possible, the driver can choose the range of parking spaces in which the vehicle must look for a space. From that moment on, the vehicle moves, looking for free places until an available one in the range selected by the driver is found. Then, the vehicle performs the parking maneuver, choosing between two alternatives to optimize the required space. Tests in a real parking lot, with spaces covered with metallic canopies, showed an accurate behavior.

Inferring the Driver's Lane Change Intention through LiDAR-Based Environment Analysis Using Convolutional Neural Networks.

Most of the tactic manoeuvres during driving require a certain understanding of the surrounding environment from which to devise our future behaviour. In this paper, a Convolutional Neural Network (CNN) approach is used to model the lane change behaviour to identify when a driver is going to perform this manoeuvre. To that end, a slightly modified CNN architecture adapted to both spatial (i.e., surrounding environment) and non-spatial (i.e., rest of variables such as relative speed to the front vehicle) input variables. Anticipating a driver's lane change intention means it is possible to use this information as a new source of data in wide range of different scenarios. One example of such scenarios might be the decision making process support for human drivers through Advanced Driver Assistance Systems (ADAS) fed with the data of the surrounding cars in an inter-vehicular network. Another example might even be its use in autonomous vehicles by using the data of a specific driver profile to make automated driving more human-like. Several CNN architectures have been tested on a simulation environment to assess their performance. Results show that the selected architecture provides a higher degree of accuracy than random guessing (i.e., assigning a class randomly for each observation in the data set), and it can capture subtle differences in behaviour between different driving profiles.

Consideraciones clínicas y desenlaces quirúrgicos del cáncer asociado a implante mamario: una enfermedad emergente de interés

El cáncer de mama sigue siendo una de las principales prioridades en salud global y salud pública y permanece como la neoplasia maligna más frecuente y mortal en mujeres en el mundo. El linfoma anaplásico de células grandes asociado a implante mamario (LACG-AIM) consiste en un linfoma no-Hodgkin de tipo raro, del cual se desconoce mucho sobre su patogenia y fisiopatología, pero que se ve cada vez con mayor frecuencia, debido al aumento de procedimientos estéticos. A la fecha, existen limitaciones en cuanto al conocimiento sobre el comportamiento clínico y se manifiesta de muchas formas, con un tiempo de evolución variable, y desenlaces quirúrgicos inciertos a mediano y largo plazo. Con base en lo anterior, el objetivo de esta revisión consiste en resumir evidencia sobre las consideraciones clínicas y desenlaces quirúrgicos del cáncer asociado a implante mamario, que faciliten la identificación y abordaje de esta condición. Se realizó una búsqueda bibliográfica en los motores de búsqueda y bases de datos PubMed, ScienceDirect, Embase, EBSCO y MEDLINE. Dentro de las consideraciones clínicas y quirúrgicas, se debe tener en cuenta el tipo de implante utilizado (texturizado), el tiempo del antecedente del implante, la severidad de las manifestaciones y la estadificación, para poder determinar la oportunidad de intervención quirúrgica y terapia neoadyuvante e intentar garantizar la supervivencia y evitar recurrencia. Aquellos pacientes sometidos a capsulectomía completa acompañado de radioterapia tienen mejores desenlaces.

Breast cancer continues to be one of the main priorities in global health and public health, and remains the most frequent and deadly malignant neoplasm in women worldwide. Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare type of Non-Hodgkin's lymphoma, whose pathogenesis and pathophysiology are not well known, but which is seen with increasing frequency due to the increase in cosmetic procedures. To date, there are limitations in terms of knowledge about the clinical behavior of the disease, which can manifest itself in many forms, with a variable evolution time and uncertain surgical outcomes in the medium- and long-term. Based on the above, the aim of this review is to summarize evidence on the clinical considerations and surgical outcomes of breast implant-associated cancer to facilitate the identification and management of this condition. A bibliographic search was performed in the search engines and databases pubmed, sciencedirect, embase, ebsco and medline. Within the clinical and surgical considerations, the type of implant used (textured), the time of the implant history, the severity of the manifestations, and the staging, must be taken into account in order to determine the opportunity for surgical intervention and neoadjuvant therapy, and to try to guarantee survival and avoid recurrence. Patients who undergo complete capsulectomy with radiotherapy have better outcomes.

Lipoinyección labial con grasa autóloga con fines estéticos / Autologous fat lipoinjection for aesthetic purposes

Introducción. La Lipoinyección de grasa autóloga con fines estéticos es una de las técnicas más jóvenes que permiten resolver problemas relacionados con valores concernientes a las elecciones personales que apuntan hacia la belleza, es un procedimiento quirúrgico sencillo y con resultados rápidos. Es una alternativa segura, real, sencilla y accesible que abarata costos, sobre todo con el uso de equipos y tecnología. Objetivos. Caracterizar los resultados estéticos de la Lipoinyección Labial con Grasa Autóloga en pacientes que asistieron a la consulta externa de Cirugía Plástica del Hospital Universitario "General Calixto García". Material y Método. Se realizó un estudio prospectivo, descriptivo, de corte transversal, en el período comprendido entre octubre de 2018 a septiembre del 2019. Se seleccionaron aquellos que cumplieron los criterios de inclusión y aceptaran a participar en el estudio voluntariamente. La muestra quedó constituida por 23 pacientes. La información obtenida se procesó mediante bases de datos confeccionadas en Excel, lo que permitió la realización de la estadística descriptiva simple para las variables individuales como media, desviación estándar y razón. La disposición a colaborar en el estudio se recogió en el modelo de Consentimiento Informado elaborado para esta investigación. Resultados. Predominio del sexo femenino en el 60.87 % de los operados. El grupo de edad entre 51 a 61 años fue el de mayor número de pacientes. Las complicaciones inmediatas más frecuentes en los labios fueron: la inflamación y los hematomas; las tardías fueron nodulaciones y endurecimiento. El 82.60 % de los pacientes se mostró satisfecho con los resultados. Conclusiones. La Lipoinyección labial con Grasa Autóloga se caracterizó por ser un método capaz de satisfacer el resultado estético. Las variables edad y sexo evidencian que las mujeres se realizaron más Cirugía Estética Labial que los hombres. Las variables clínicas labios finos y volumen evidencian que el aumento de la edad es una condición importante que se asocia a la demanda de esta técnica quirúrgica y que el ser hombre o mujer no establece una diferencia para la solitud de este tipo de técnica quirúrgica. Se presentaron complicaciones inmediatas y tardías. Los niveles de satisfacción expresados por los pacientes fueron altos.
