In a healthy heart, the mechano-electric feedback (MEF) process acts as an intrinsic regulatory mechanism of the myocardium which allows the normal cardiac contraction by damping mechanical perturbations in order to generate a new healthy electromechanical situation. However, under certain conditions, the MEF can be a generator of dramatic arrhythmias by inducing local electrical depolarizations as a result of abnormal cardiac tissue deformations, via stretch-activated channels (SACs). Then, these perturbations can propagate in the whole heart and lead to global cardiac dysfunctions. In the present study, we examine the spatio-temporal behavior of the autonomous electrical activity induced by the MEF when the heart is subject to temperature variations. For instance, such a situation can occur during a therapeutic hypothermia. This technique is usually used to prevent neuronal injuries after a cardiac resuscitation. From this perspective, we introduce a one-dimensional time-dependent model containing all the key ingredients that allow accounting for excitation-contraction coupling, MEF and thermoelectric coupling. Our simulations show that an autonomous electrical activity can be induced by cardiac deformations, but only inside a certain temperature interval. In addition, in some cases, the autonomous electrical activity takes place in a periodic way like a pacemaker. We also highlight that some properties of the action potentials that are generated by the MEF, are significantly influenced by temperature. Moreover, in the situation where a pacemaker activity occurs, we also show that the period is heavily temperature-dependent. [less ▲]

The AMM is a development tool for integration of various off-self-sensors in one miniaturized device (1cm³). It can be used for wide variety applications such: industrial, buildings, healthcare and others. In normal environmental conditions, the autonomy is achieved by photovoltaic cell and the sensors are used for monitoring temperature, humidity and light intensity. At harsh environment such as a liquid zinc bath (800°C), the specially developed package allows the system to monitor inputs. [less ▲]

Microsys has developed an Autonomous Micro-platform for Multi-sensors integration (AMM). The AMM is a development tool/platform for integration of various off-self-sensors in one miniaturized device (1cm³). Depends of the sensor choice AMM can be used for various applications such: industrial, buildings, healthcare and others. Using the AMM platform, we developed an autonomous system for monitoring temperature, humidity, vibration, light and light intensity sound level. The autonomy is achieved by photovoltaic cell. In total we fabricated 15 fully functional prototypes. [less ▲]

We present a reflector service that seeks to maintain application-level connectivity in the presence of network-level multicast failures. The service is based on the dynamic deployment of autonomous reflectors based on mobile code, on top of an active network infrastructure. It is able to repair multicast tree failures by building a self-organising tree of reflectors, which will be connected to each other via unicast. We focus on the basic decision mechanisms related to code mobility during the tree construction and destruction phases, namely: cloning, migration, merging and termination. To assist with the decisions a market-based mechanism is employed. We show some preliminary simulation results that confirm the viability of the approach and settle directions for further research.

We present a reflector service that seeks to maintain application-level connectivity in the presence of network-level multicast failures. The service is based on the dynamic deployment of autonomous reflectors modelled as mobile agents on top of an active network infrastructure. It is able to repair multicast tree failures by building a self-organising tree of reflectors, which will be connected to each other via unicast. The scheme is decentralised and takes into account node and link resources to find agent locations that lead to low cost tree configurations. We focus on the basic decision mechanisms related to code mobility during the tree construction and destruction phases, namely: cloning, migration, merging and termination. We show some preliminary simulation results that confirm the viability of the approach and settle directions for further research. [less ▲]

This paper studies some extensions to the decentralized attitude synchronization of identical rigid bodies. Considering fully actuated Euler equations, the communication links between the rigid bodies are limited and the available information is restricted to relative orientations and angular velocities. In particular, no leader nor external reference dictates the swarm's behavior. The control laws are derived using two classical approaches of nonlinear control - tracking and energy shaping. This leads to a comparison of two corresponding methods which are currently considered for distributed synchronization - consensus and stabilization of mechanical systems with symmetries. [less ▲]

Control laws to synchronize attitudes in a swarm of fully actuated rigid bodies, in the absence of a common reference attitude or hierarchy in the swarm, are proposed in [Smith, T. R., Hanssmann, H., & Leonard, N.E. (2001). "Orientation control of multiple underwater vehicles with symmetry-breaking potentials". In Proc. 40th IEEE conf. decision and control (pp. 4598–4603); Nair, S., Leonard, N. E. (2007). "Stable synchronization of rigid body networks". In Networks and Heterogeneous Media, 2(4), 595–624]. The present paper studies two separate extensions with the same energy shaping approach: (i) locally synchronizing the rigid bodies’ attitudes, but without restricting their final motion and (ii) relaxing the communication topology from undirected, fixed and connected to directed, varying and uniformly connected. The specific strategies that must be developed for these extensions illustrate the limitations of attitude control with reduced information. [less ▲]

A 51-year-old female patient with long-standing hyperthyroidism due to a thyrotropin-secreting pituitary adenoma is reported, who became thyrotoxic again shortly after successful pituitary surgery. Functional testing and scintigraphy suggested the diagnosis of autonomous functioning thyroid nodules, which was confirmed by pathological examination of the resected thyroid tissue. This is the first report revealing the transition from a pituitary-dependent to a thyroid-dependent hyperthyroidism. Autonomous functioning thyroid nodules are, however, considered an intrinsic thyroid defect. In similarity with other disorders, in which trophic hormones may induce an autonomous secretion by the target gland, this report opens the possibility that a humoral factor may play a role in the development of autonomous functioning thyroid nodules.
