Abstract:

SUMMARYIn order to widen the potentialities of manipulation of the Laboratoire de Mécanique des solides (LMS) mechanical hand, we developed a new planning approach based on the use of a specific exoskeleton. This one has kinematics architecture and dimensions identical to the mechanical hand. This feature allows us to obtain manipulation trajectories for the mechanical hand, very easily and very quickly, by using the exoskeleton, without complex calibration. Manipulation's trajectories are replayed offline with an autonomous control, and, consequently, the exoskeleton is not used with any feed

Abstract:

The various biometrical criteria used in the study of the population structure of the annelid polychaete Nereis virens (Sars) are reviewed. This type of study, which requires the examination of large numbers of specimens representing all size classes, is sometimes complicated by the occurrence of autotomy, a phenomenon quite frequent in this species, and by mechanical breaks during sampling and sieving. Measurements such as total length, width of an anterior segment, and total weight are not good criteria. We have used a new biometrical criterium developed at the Laboratoire maritime de Dinard

SUMMARYThis paper presents a novel tendon-driven bio-inspired robotic hand design for in-hand manipulation. Many dexterous robot hands are able to produce adaptive grasping, but only a few human-sized hands worldwide are able to produce fine motions of the object in the hand. One of the challenges for the near future is to develop human-sized robot hands with human dexterity. Most of the existing hands considered in the literature suffer from dry friction which creates unwanted backlash and non-linearities. These problems limit the accurate control of the fingers and the capabilities of the ha

Abstract Ocean acidification has been identified as a risk to marine ecosystems, and substantial scientific effort has been expended on investigating its effects, mostly in laboratory manipulation experiments.

Abstract:

Objective. The goal of this study was to examine the theoretical feasibility of a new manipulator system for endoscope guidance in functional endoscopic sinus surgery. Study Design. The accuracy of endoscope positioning and time of endoscope movement with an endoscope manipulator system were determined with an artificial sinus model. Setting. A laboratory trial was performed. The time for 60 repetitions of manual compared to manipulator-assisted endoscope movements directed at 3 different target positions was evaluated. In addition, the alignment of the position vector for each endoscope movem

Abstract:

The importance of genetic laboratory models, such as mice and rats, becomes evident when there is a poor understanding of the nature of human disease. Many rat models for human disease, created over the years by phenotype-driven strategies, now provide a foundation for the identification of their genetic determinants. These models are especially valuable with the emerging need for validation of genes found in genome-wide association studies for complex diseases. The manipulation of the rat genome using engineered zinc-finger nucleases now introduces a key technology for manipulating the rat ge

Abstract:

Growing evidence suggests that resource scarcity can severely impede individuals’ cognitive capacity, resulting in sub-optimal decision making. Few experimental studies investigate whether food deprivation as a form of resource scarcity influences decisions in other non-hunger related domains. We examine the effect of short term fasting on cognitive capacity by exogenously manipulating individuals’ fasting time in a laboratory experiment. Participants were randomly assigned to one of three treatments: 1) 3-hour fast; 2) 12-hour fast; and 3) control, in which participants were not required to f

Abstract:

The inability to maintain signal detection performance with time on task, or vigilance decrement, is widely studied in people. Despite suggestions that limitations in sustained attention may be a fundamental characteristic of animal cognition, there has been limited research on the vigilance decrement in other animals. We conducted two experiments to explore vigilance in jumping spiders. Our first experiment established that the vigilance decrement, decline in signal detections with time on task, occurs in these spiders in laboratory settings. Our second experiment tested whether this phenomen

In this paper a procedure is proposed for a rational and optimum use of robots. It is the result of the lessons learned by the author in the course of his consultancy and teaching activities on manipulative tasks and programming capabilities of robots.One of the chief aims of this paper is educational, and has been set on the basis of students' practice with robots in the Laboratory of Robotics at the University of Cassino, Italy. A second goal consists in highlighting and teaching how robots' versatility and flexibility can be easily exploited during robot's operation when a task is properly

Abstract:

Understanding how humans navigate the tension between selfish and prosocial behaviour is central to addressing social dilemmas and several environmental issues. Many accounts predict that human prosociality would increase in the presence of observing individuals. Previous studies on this observability effect predominantly relied on artificial observability manipulations and low-cost measures of prosociality. In the present Registered Report, we used a recently validated laboratory procedure of repeated dilemmas to test whether the presence of actual observers affects costly prosocial behaviour

Abstract:

SUMMARYA new control strategy based on the singular perturbation method and integral manifold concept is introduced for flexible-joint manipulators with joint friction. In controllers so far developed based on the singular perturbation theory, the dynamics of actuators of flexible-joint manipulators are partially modelled, and the coupling between actuators and links is ignored. This assumption leads to inaccuracy in control performance and error in trajectory tracking which is crucial in high-precision manipulation tasks. In this paper, a comprehensive dynamic model which takes into account t

Abstract:

Responding to the concern from our faculty that undergraduate students do not have robust laboratory skills, we designed and implemented a strategy to individually teach and assess the manipulative skills of students in first-year laboratories. Five core laboratory skills were selected for the course entitled Human Biology, a large, first-year class of students, most of whom were enrolled in Bachelor of Pharmacy and Human Movement Studies. Here, we report details for the 365 students enrolled primarily in Pharmacy and Human Movement Studies bachelor degree programs in semester 1 of 2006. We de

We describe an improved allelic-exchange method for generating unmarked mutations and chromosomal DNA alterations in enterobacterial species. Initially developed for use in Salmonella enterica, we have refined the method in terms of time, simplicity, and efficiency. We have extended its use into related bacterial species that are more recalcitrant to genetic manipulations, including enterohemorrhagic and enteropathogenic Escherichia coli and Vibrio parahaemolyticus. Data from over 50 experiments are presented including gene inactivations, site-directed mutagenesis, and promoter exchanges. In e
