We consider the design of a disagreement correction protocol in multi-vehicle systems. Vehicles broadcast in real-time vital information such as position, direction, speed, acceleration, intention, etc. This information is then used to identify the risks and adapt their trajectory to maintain the highest performance without compromising the safety. To minimize the risk due to the use of inconsistent information, all cooperating vehicles must agree whether to use the exchanged information to operate in a cooperative mode or use the only local information to operate in an autonomous mode...

The name Bufo brasiliensis was proposed by Laurenti (1768) and, for a long time, has been associated with the widely distributed Marine toad - Rhinella marina (Linnaeus, 1758). However, we found several inconsistences in this taxonomic proposal and disagree with it. We argue that the specimen illustrated does not correspond to any bufonid form (even less the Neotropical genus Rhinella) based on the following argumentation presented below. Laurenti (1768) used Seba's (1734) illustration in plate 73 (Fig. 1) to establish the name B...

Baird et al. (2015) split Lasiurus into three distinct genera (Aeorestes, Dasypterus and Lasiurus) based on tree topology and divergence times for the tribe Lasiurini. This arrangement has not been widely adopted by the scientific community and was criticized by Ziegler et al. (2016). More recently, Baird et al. (2017) reinforced the taxonomic arrangement of Lasiurini comprised by three genera. Baird et al. (2015, 2017) provided the most comprehensive phylogenetic analyses of Lasiurus and offer important insights on the phylogeny and alpha-taxonomy of the group...

Experiments on theories of reference have mostly tested referential intuitions. We think that experiments should rather be testing linguistic usage. Substantive Aim (I): to test classical description theories of proper names against usage by "elicited production." Our results count decisively against those theories. Methodological Aim (I): Machery, Olivola, and de Blanc () claim that truth-value judgment experiments test usage. Martí () disagrees. We argue that Machery et al. are right and offer some results that are consistent with that conclusion...

Background: Plasma amino acid measurements have been extensively investigated in individuals with autism spectrum disorder (ASD). Results thus far have been inconclusive as studies generally disagree on which amino acids are different in individuals with ASD versus their typically developing (TD) peers, due in part to methodological limitations of several studies. Method: This paper investigates plasma amino acids in children and adults with ASD using data from Arizona State University's Comprehensive Nutritional and Dietary Intervention Study...

OBJECTIVE: As operative experience in general surgery decreases and work hour limitations increase there is less exposure of surgical residents to advanced vascular and trauma exposures. Many institutions have demonstrated benefits of cadaver laboratory courses. We have incorporated a multimedia cadaver laboratory course into our general surgery residency didactics curriculum with the objective to demonstrate a benefit of the program as well as the feasibility of incorporation. STUDY DESIGN: This is a prospective study at a tertiary care institution including general surgery residents within our residency program...

Patient satisfaction surveys are an increasingly common element of efforts to evaluate the quality of healthcare. Many patient satisfaction surveys in low/middle-income countries frame statements positively and invite patients to agree or disagree, so that positive responses may reflect either true satisfaction or bias induced by the positive framing. In an experiment with more than 2200 patients in Nigeria, we distinguish between actual satisfaction and survey biases. Patients randomly assigned to receive negatively framed statements expressed significantly lower levels of satisfaction (87%) than patients receiving the standard positively framed statements (95%-p<0...

BACKGROUND: The common practice of performing concurrent or overlapping surgeries has been intensely scrutinized by lay media and academic press to investigate its safety and cost-effectiveness. However, there is little information about its use within the pediatric population. Even less is known about parents' expectations regarding the surgeon's role on the day of surgery and how they align with those of pediatric surgeons and surgical trainees, despite the potential for significant discrepancies in expectations to erode trust and damage the physician-family relationship...

Objective: Standardized patient (SP) scenarios could provide medical situations of high fidelity for teaching or examinations, which would otherwise be difficult with real patients. Moreover, SPs can also be used to reliably evaluate or certify the competence of medical trainees. Since the interactions between examinee and SP are dynamic and complex, SPs need to portray the case reliably and consistently across different examinees. Thus, we developed a 1-day program for newly recruited SPs to teach basic competence in case portrayal...

The possibility that diet-derived miRNAs survive the gastrointestinal tract and exert biological effects in target cells is triggering considerable research in the potential abilities of alimentary preventive and therapeutic approaches. Many validation attempts have been carried out and investigators disagree on several issues. The barriers exogenous RNAs must surpass are harsh and adequate copies must reach target cells for biological actions to be carried out. This prospect opened a window for previously unlikely scenarios concerning exogenous non-coding RNAs, such as a potential role for breast milk microRNAs in infants' development and maturation...

Immature cognition is susceptible to interference from competing information, and particularly in affectively charged situations. Several studies have reported activation in the anterior cingulate cortex, prefrontal cortex and amygdala associated with emotional conflict processing in adults but literature is lacking regarding children. Moreover, studies in children and adolescents still disagree regarding the functional activation of amygdala related to facial stimuli. In the purpose of investigating both the effect of socio-emotional stimuli and its interaction with interference control, we designed a flanker task associated with an event-related fMRI paradigm in 30 healthy children ages 9-11...
