    Abstract We consider robotic pick-and-place of partially visible, novel objects, where goal placements are non-trivial, e.g., tightly packed into a bin. One approach is (a) use object instance segmentation and shape completion to model the objects and (b) use a regrasp planner to decide grasps and places displacing the models to their goals. However, it is critical for the planner to account for uncertainty in the perceived models, as object geometries in unobserved areas are just guesses. We account for perceptual uncertainty by incorporating it into the regrasp planner's cost function. We compare seven different costs. One of these, which uses neural networks to estimate probability of grasp and place stability, consistently outperforms uncertainty-unaware costs and evaluates faster than Monte Carlo sampling. On a real robot, the proposed cost results in successfully packing objects tightly into a bin 7.8% more often versus the commonly used minimum-number-of-grasps cost.

    Abstract Introduction: Previous functional near-infrared (fNIRS) studies using Go/No-Go (GNG) tasks have focused on brain activation in relation to cognitive processes, particularly inhibitory control (IC). The results of these studies commonly describe right hemispheric engagement of the dorsolateral, ventromedial or inferior frontal regions of the prefrontal cortex (PFC). Considering that typical healthy cognitive development is negatively correlated with higher cortisol levels (which may alter brain development), the overarching aim of the current study was to investigate how elevated stress (due to unforeseeable events such as the pandemic) impacts early cognitive development.
    Method: In this study, we examined fNIRS data collected from a sample of children (aged 2 - 4 years) during a GNG task relative to the response to stressors measured via hair cortisol concentrations. We acquired data in an ecological setting (Early Childhood Education and Care) during the coronavirus pandemic.
    Results: We found that children with higher stress levels and a less efficient inhibitory control recruited more neural terrain and our group-level analysis indicated activation in the left orbitofrontal area during IC performance.
    Conclusions: A contextual stressor may disrupt accuracy in the executive function of inhibitory control early in development. More research efforts are needed to understand better how an orbitofrontal network subserves goal-directed behavior.

    Abstract COVID-19 pandemic had a significant impact on global public health. The spread of the disease was related to the high transmissibility of SARS-CoV-2 virus but incidence and mortality rate suggested a possible relationship with environmental factors. Air pollution has been hypothesized to play a role in the transmission of the virus and the resulting severity of the disease. Here we report a plausible in vitro toxicological mode of action by which fine particulate matter (PM

    Abstract Mandibular fractures are the second most common maxillofacial fractures. The prevalent treatment for this kind of fractures is either a surgical procedure such as maxillomandibular fixation or open reduction and internal fixation or a combination of both. Sometimes the patients might develop locoregional postoperative complications. The most frequently reported complications are trigeminal V3 injury and surgical site infection. A 4-year retrospective study was performed at the Department of Oral and Maxillofacial Surgery, Policlinico Umberto I of Rome, Italy, and the postoperative complications after mandibular fracture surgical treatment were collected. The authors studied the characteristics of each complication and the correlation with the type of mandibular fracture and the surgical treatment chosen.

    Abstract Research on olfactory stimulation indicates that it can influence human cognition and behavior, as in the perception of facial expressions. Odors can facilitate or impair the identification of facial expressions, and apparently its hedonic valence plays an important role. However, it was also demonstrated that the presentation of happiness and disgust faces can influence the emotional appraisal of odorants, indicating a bilateral influence in this phenomenon. Hence, it's possible that odor influences on emotional categorization vary depending on the intensity of expressions. To investigate this hypothesis, we performed an emotion recognition task using facial expressions of five emotional categories (happiness, fear, disgust, anger and sadness) with ten different intensities. Thirty-five participants completed four blocks of the task, each with a different olfactory condition, and we found that odorants' effects varied according to the facial expressions intensity. Odorants enhanced the Reaction Time (RT) differences between threshold and high-intensity expressions for disgust and fear faces. Also, analysis of the RT means for high-intensity facial expressions revealed that the well-known advantage in recognition of happiness facial expressions, compared to other emotions, was enhanced in the positive olfactory stimulation and decreased in the negative condition. We conclude that olfactory influences on emotional processing of facial expressions vary along intensities of the latter, and the discrepancies of past research in this field may be a result of a bilateral effect in which the odorants influence the identification of emotional faces just as the facial expressions influence the emotional reaction to the odor.

    Abstract The production and use of nanomaterials (NMs) has increased over the last decades posing relevant questions on their risk after release and exposure of the population or sub-populations. In this context, the safe and sustainable by design (SSbD) approach framework requires to assess the potential hazard connected with intrinsic properties of the material along the whole life cycle of the NM and/or of the nano enabled products. Moreover, in the last years, the use of new advanced methodologies (NAMs) has increasingly gained attention for the use of alternative methods in obtaining relevant information on NMs hazard and risk. Considering the SSbD and the NAMs frameworks, within the ASINA H2020 project, we developed new NAMs devoted at improving the hazard and risk definition of different Ag and TiO2 NPs. The NAMs are developed considering two air liquid interface exposure systems, the Vitrocell Cloud-α and the Cultex Compact module and the relevant steps to obtain reproducible exposures are described. The new NAMs build on the integration of environmental monitoring campaigns at nano-coating production sites, allowing the quantification by the multiple-path particle dosimetry (MPPD) model of the expected lung deposited dose in occupational settings. Starting from this information, laboratory exposures to the aerosolized NPs are performed by using air liquid interface exposure equipment and human alveolar cells (epithelial cells and macrophages), replicating the doses of exposure estimated in workers by MPPD. Preliminary results on cell viability and inflammatory responses are reported. The proposed NAMs may represent possible future reference procedures for assessing the NPs inhalation toxicology, supporting risk assessment at real exposure doses.

    Abstract Mosaic analysis in Drosophila represents a convenient entry point for studying the role of ESCRT (Endosomal Sorting Complex Required for Transport) genes in multiple cell processes crucial for organ development and homeostasis. Here, we describe the procedure to generate populations of ESCRT-mutant cells within Drosophila larval epithelial organs and to study them in whole-mount preparations using confocal microscopy. The use of antibodies directed to endocytic cargoes, vesicular trafficking, cell proliferation, death, and polarity markers allows one to investigate the consequences of loss of ESCRT activity at the subcellular and tissue level. The protocols described here can be used in fixed tissue as well as in unfixed tissue using endocytic uptake assays.
