1. Step-by-step optimisation of robotic-assisted radical prostatectomy using augmented reality
ABSTRACT Introduction: Surgical training will be complemented by digitalisation, as the COVID 19 pandemic continues (1). Proximie is an augmented reality (AR) platform that can display up to 4 native camera views, with live or semi live telementoring. It can optimise ergonomics of the surgeon at the console (2), and robotic instrument orientation. We descri

3. Analytical solution for nonlinear dynamic behavior of viscoelastic nano-plates modeled by consistent couple stress theory
Abstract This paper analyses the non-stationary free vibration and nonlinear dynamic behavior of the viscoelastic nano-plates. For this purpose, a size-dependent theory is developed in the framework of the consistent couple stress theory for viscoelastic materials. The previously presented modified couple stress theory was based on some consideration making

4. A New Buffer in Impact Reduction for Aerospace Applications
Abstract The aim of this paper is to introduce a new buffering mechanism in impact reduction during assembly process of two space vehicles. Probe-cone mechanism, due to its computational easiness, is employed to study impact interaction between multibody systems. The proposed buffer with a compact structure includes a probe equipped with axial and torsional

5. Reconstruction of gait biomechanical parameters using cyclograms and artificial neural networks
Abstract Introduction Historically, assessing the quality of human gait has been a difficult process. Advanced studies can be conducted using modern 3D systems. However, due to their high cost, usage of these 3D systems is still restricted to research environments. 2D systems offer simpler and more affordable solutions. Methods In this study, the gait of 4

6. Influence of a virtual reality-based exercise protocol on the sit-to-stand activity kinematic variables in pregnant women: a randomized controlled trial
Abstract AIMS Changes resulting from the gestational period may lead to changes in the biomechanics of women, which can alter the performance of functional activities such as sit-to-stand. Thus, the objective of this study was to investigate the influence of a virtual reality-based exercise protocol on the kinematic variables of the sit-to-stand movement in

7. Multicenter trial of motion analysis for injury risk prediction: lessons learned from prospective longitudinal large cohort combined biomechanical - epidemiological studies
ABSTRACTOur biodynamics laboratory group has conducted large cohort biomechanical-epidemiological studies targeted at identifying the complex interactions among biomechanical, biological, hormonal, and psychosocial factors that lead to increased risk of anterior cruciate ligament (ACL) injuries. The findings from our studies have revealed highly sensitive an

8. The use of pelvic fins for benthic locomotion during foraging behavior in Potamotrygon motoro (Chondrichthyes: Potamotrygonidae)
Synchronized bipedal movements of the pelvic fins provide propulsion (punting) during displacement on the substrate in batoids with benthic locomotion. In skates (Rajidae) this mechanism is mainly generated by the crural cartilages. Although lacking these anatomical structures, some stingray species show modifications of their pelvic fins to aid in benthic l

9. Influência do treino em esteira na marcha em dupla tarefa em indivíduos com Doença de Parkinson: estudo de caso
A perda na automaticidade da marcha dificulta a realização de atividades concorrentes - Dupla Tarefa (DT) - em indivíduos com Doença de Parkinson (DP). Uma hipótese para a interferência negativa da DT sobre a marcha está relacionada à limitação de recursos cerebrais atentivos para as diferentes atividades. Caso ocorra a automatização de uma das t

10. Vibroacoustography for the assessment of total hip arthroplasty
OBJECTIVES: This paper proposes imaging with 3-dimensional vibroacoustography for postoperatively assessing the uncovered cup area after total hip arthroplasty as a quantitative criterion to evaluate implant fixation. METHODS: A phantom with a bone-like structure covered by a tissue-mimicking material was used to simulate a total hip arthroplasty case. Vi

11. ComunicaÃÃo cinÃsica do recÃm-nascido sob influÃncia do manuseio e ruidos em uma unidade neonatal / Kinesic communication of newborn related to the handling of health and noise in neonatal intensive care unit
The kinesics capture of newborns admitted to Neonatal Units (NUs) is necessary for a care based on humanization. The objective was to assess the kinesics of newborns in a NU, related to the handling of health professionals and noise produced in the Unit, according to Birdwhistell (1985). Descriptive exploratory study of quantitative approach carried out at N

12. Capture and 3D modeling of hands with motion tracking / Captura e modelagem 3D de mãos com rastreamento de movimentos
Currently, general-purpose computers come equipped with webcams cameras of good resolution and high-speed, which enables a visually user interaction, through gestures, with software applications. This allows a greater sense of reality in interactive processes of virtual and augmented reality. The goal of this research is to capture and compose 3D model of ha
