The sharpness of the images coming from a Scanning Electron Microscope (SEM) is a very important property for many computer vision applications at micro- and nanoscale. It represents how much object details are distinctive in the images: the object may be perceived sharp or blurred. Image sharpness highly depends on the value of focal distance, or working distance in the case of the SEM. Autofocus is the technique allowing to automatically adjust the working distance to maximize the sharpness. Most of the existing algorithms allows working only with a static object which is enough for the tasks of visualization, manual microanalysis or microcharacterization...

The field of laparoscopic surgery has continued to grow exponentially over the years, prompting new innovative technologies. Despite substantial advancements, standard laparoscopic tools have undergone little design changes and fail to optimize mobility in limited spaces. Advancements in robotics have attempted to address this, allowing for increasing degrees of freedom and articulation of instruments. Even so, this system has proven to be cumbersome with questionable cost-effectiveness. In this study, we present the first use of a solely mechanical intuitively controlled articulating laparoscopic needle driver...

People sometimes perceive a mind in inorganic entities like robots. Psychological research has shown that mind perception correlates with moral judgments and that immoral behaviors (i.e., intentional harm) facilitate mind perception toward otherwise mindless victims. We conducted a vignette experiment (N = 129; Mage = 21.8 ± 6.0 years) concerning human-robot interactions and extended previous research's results in two ways. First, mind perception toward the robot was facilitated when it received a benevolent behavior, although only when participants took the perspective of an actor...

BACKGROUND: Over the last decade, robotic approaches have been described for removing adrenal tumors. Although there are reports comparing robotic and laparoscopic techniques in general, there are limited data on outcomes in patients with primary hyperaldosteronism (PHA). The aim of this study is to compare the safety and efficacy of robotic adrenalectomy (RA) versus laparoscopic adrenalectomy (LA) for PHA. MATERIALS AND METHODS: The records of 20 patients who underwent RA for PHA were compared with 16 patients who underwent LA between 2000 and 2014...

The laparoscopic approach has gained acceptance in the field of hepatopancreaticobiliary surgery. It offers several advantages including reduced blood loss, reduced postoperative pain, and shorter length of stay. However, long operating times can be associated with surgeon and assistant fatigue and image tremor. Robotic camera holders have been designed to overcome these drawbacks but may come with significant costs. The aim of this study was to economically evaluate their use compared with standard assistants using a single surgeon consecutive series of laparoscopic liver resections from January 2014 to May 2015...

In this study, a multimodal fusion framework based on three different modal biosignals is developed to recognize human intentions related to lower limb multi-joint motions which commonly appear in daily life. Electroencephalogram (EEG), electromyogram (EMG) and mechanomyogram (MMG) signals were simultaneously recorded from twelve subjects while performing nine lower limb multi-joint motions. These multimodal data are used as the inputs of the fusion framework for identification of different motion intentions...

This paper illustrates a new architecture for a human-humanoid interaction based on EEG-Brain Computer Interface (EEG-BCI) for patients affected by locked-in syndrome caused by Amyotrophic Lateral Sclerosis (ALS). The proposed architecture is able to recognise users' mental state accordingly to the biofeedback factor Bf , based on users' Attention, Intention and Focus, that is used to elicit a robot to perform customised behaviours. Experiments have been conducted with a population of 8 subjects: 4 ALS patients in a near Locked-in status with normal ocular movement and 4 healthy control subjects enrolled for age, education and computer expertise...

Matrix-assisted laser desorption/ionization (MALDI) coupled with a time-of-flight (TOF) mass-spectrometry (MS) detector is acknowledged to be very useful for analysis of biological molecules. At the same time, hydrogen-deuterium exchange (HDX) is a well-known technique for studying protein higher-order structure. However, coupling MALDI with HDX may be challenging due to undesired back-exchange reactions during analysis. In this report, we survey an approach that utilizes MALDI coupled with automated sample preparation to compare global conformational changes of proteins under different solution conditions using differential HDX...

In Japan, colorectal endoscopic submucosal dissection (ESD) is being conducted safely and effectively as shown by the increased number of the cases, however, it is still regarded as a complicated and challenging procedure. Therefore, piecemeal endoscopic mucosal resection (p-EMR) is still regarded as an appropriate treatment, rather than ESD for large colorectal tumors, especially in Western countries. Areas covered: There are several factors that are responsible for colorectal ESD difficulty. Firstly, there is no adequate traction or counter-traction in colorectal ESD...

PURPOSE: Surgical robots with cooperative control and semiautonomous features have shown increasing clinical potential, particularly for repetitive tasks under imaging and vision guidance. Effective performance of an autonomous task requires accurate hand-eye calibration so that the transformation between the robot coordinate frame and the camera coordinates is well defined. In practice, due to changes in surgical instruments, online hand-eye calibration must be performed regularly. In order to ensure seamless execution of the surgical procedure without affecting the normal surgical workflow, it is important to derive fast and efficient hand-eye calibration methods...

Postoperative wound healing can pose a problem in patients undergoing instrumented surgery for pyogenic spondylodiscitis. Robotic guidance allows the minimally invasive placement of pedicle screws in the thoracolumbar spine. We assessed whether using this technique to perform minimally invasive surgery had an impact on wound healing in patients with pyogenic spondylodiscitis when compared to conventional open fluoroscopy-guided surgery. We reviewed charts of 206 consecutive patients who underwent instrumentation for pyogenic spondylodiscitis...
