[Ab] Resumo:Biophysics, just by looking at its name, indicates an interdisciplinary scientific activity, although the notion of interdisciplinarity, as such, seems to be not widely or specifically discussed by biophysicists. The same seems to have happened as well in the early stages of the development of cybernetics, notably in Norbert Wiener's writings. This situation seems to contrast with what has happened in subsequent developments of cybernetics ideas, notably in general system theory and cognitive sciences. After a few general reflections on the notion of interdisciplinarity, its sophisticated variants and the path leading to the birth of cognitive science, we shall refer to Wiener's thought to extracts aspects and indications that could be useful today, also for what concerns the social responsibility of scientists, which could be seen as stemming from a very general form of interdisciplinarity. HIGHLIGHTS: After a few general reflections on the notion of interdisciplinarity, its sophisticated variants and the path leading to the birth of cognitive science, we shall refer to Wiener's thought to extracts aspects and indications that could be useful today, also for what concerns the social responsibility of scientists.

[Ti] Título:Bioengineering and Cybernetics: A Modern Caduceus.

[Ab] Resumo:Like the caduceus, a medical symbol of entwined serpents, bioengineering and cybernetics have interwoven together ideas and concepts for over 50 years. Half a century is a long time, and whether we are talking about an academic discipline, our lives, or an old car, achieving 50 is a number that brings pause to the conversation. In books, wine, or collectibles, 50 years is termed vintage, which carries the connotation of depth and maturity. Certainly, in the case of the discipline of bioengineering, 50 years is a milestone of growth and development. By all academic measures (number of departments, current enrollment and graduates, size of faculty, and impact factor for its publications), bioengineering is a mature discipline. Presently, there are almost 100 ABET-certified bioengineering degree programs in the United States alone.

[Ti] Título:Multi-Robot Coalitions Formation with Deadlines: Complexity Analysis and Solutions.

[Ab] Resumo:Multi-robot task allocation is one of the main problems to address in order to design a multi-robot system, very especially when robots form coalitions that must carry out tasks before a deadline. A lot of factors affect the performance of these systems and among them, this paper is focused on the physical interference effect, produced when two or more robots want to access the same point simultaneously. To our best knowledge, this paper presents the first formal description of multi-robot task allocation that includes a model of interference. Thanks to this description, the complexity of the allocation problem is analyzed. Moreover, the main contribution of this paper is to provide the conditions under which the optimal solution of the aforementioned allocation problem can be obtained solving an integer linear problem. The optimal results are compared to previous allocation algorithms already proposed by the first two authors of this paper and with a new method proposed in this paper. The results obtained show how the new task allocation algorithms reach up more than an 80% of the median of the optimal solution, outperforming previous auction algorithms with a huge reduction of the execution time.

[Ti] Título:Reflecting on Jens Rasmussen's legacy (2) behind and beyond, a 'constructivist turn'.

[Ab] Resumo:This article is the second part of a study on the legacy of Jens Rasmussen. The first article, subtitled 'A Strong Program for a Hard Problem', looks back on his 30 years of scientific contribution, from 1969 to 2000. This second article explores and investigates some of the intellectual roots which influenced his thinking, using them as a basis to understand some limits and move forward. Indeed, historically oriented studies such as this one are not only tributes to researchers, but a way to differentiate and contrast our present situation with the past in order to integrate contemporary trends, be they theoretical or empirical, or oriented towards research and new models. In the first section of this article, I offer a synthesis of the background covered in the previous article, but I use a tree here as a graphical complement. Branches of the tree show the many fruitful directions opened by Jens Rasmussen, directions which inspired many researchers. In the second part, I address what I believe to be behind this wealth of engineering legacy: cybernetics. I contend that cybernetics has had a profound influence on his thinking and provided him key principles for his inspiring and successful models. To develop the tree image, one might say that cybernetics is the trunk of the tree. Finally, in the third part, I take the opportunity to explore the relevance of extending and sensitising his program to constructivist discourses. After an introduction to this discourse, identifying four types of constructivisms (cognitive, social, epistemological and anthropological), I characterise this move as a 'constructivist turn'.

[Ti] Título:Anticipation: Beyond synthetic biology and cognitive robotics.
[So] Source:Biosystems;148:22-31, 2016 Oct.
[Is] ISSN:1872-8324
[Cp] País de publicação:Ireland
[La] Idioma:eng
[Ab] Resumo:The aim of this paper is to propose that current robotic technologies cannot have intentional states any more than is feasible within the sensorimotor variant of embodied cognition. It argues that anticipation is an emerging concept that can provide a bridge between both the deepest philosophical theories about the nature of life and cognition and the empirical biological and cognitive sciences steeped in reductionist and Newtonian conceptions of causality. The paper advocates that in order to move forward, cognitive robotics needs to embrace new platforms and a conceptual framework that will enable it to pursue, in a meaningful way, questions about autonomy and purposeful behaviour. We suggest that hybrid systems, part robotic and part cultures of neurones, offer experimental platforms where different dimensions of enactivism (sensorimotor, constitutive foundations of biological autonomy, including anticipation), and their relative contributions to cognition, can be investigated in an integrated way. A careful progression, mindful to the deep philosophical concerns but also respecting empirical evidence, will ultimately lead towards unifying theoretical and empirical biological sciences and may offer advancement where reductionist sciences have been so far faltering.

[Ti] Título:The steps that can take us miles: Examining the short-term dynamics of long-term daily goal pursuit.

[Ab] Resumo:Cybernetic models suggest that to achieve one's long-term goals, one must create specific plans, enact these plan, monitor progress toward the goal, and resist temptations. Although many studies have examined these proposals in laboratory settings, few studies have examined such processes in daily life. This was the explicit purpose of the current investigation. Participants identified 4 long-term goals during an orientation session. They then completed a diary protocol in which they reported on these self-regulatory processes. The results were largely consistent with predictions. Of the 20 hypotheses examined, 17 were significant in the expected direction. For example, testing led to the initiation of long-term goal operations, which in turn led to goal progress. Likewise, temptations led to self-control operations, which in turn led to the successful resistance of temptations. The investigation thus suggests that cybernetic principles have broad relevance to understanding goal pursuit in daily life.

[Ti] Título:Security Assessment of Cyberphysical Digital Microfluidic Biochips.

[Ab] Resumo:A digital microfluidic biochip (DMFB) is an emerging technology that enables miniaturized analysis systems for point-of-care clinical diagnostics, DNA sequencing, and environmental monitoring. A DMFB reduces the rate of sample and reagent consumption, and automates the analysis of assays. In this paper, we provide the first assessment of the security vulnerabilities of DMFBs. We identify result-manipulation attacks on a DMFB that maliciously alter the assay outcomes. Two practical result-manipulation attacks are shown on a DMFB platform performing enzymatic glucose assay on serum. In the first attack, the attacker adjusts the concentration of the glucose sample and thereby modifies the final result. In the second attack, the attacker tampers with the calibration curve of the assay operation. We then identify denial-of-service attacks, where the attacker can disrupt the assay operation by tampering either with the droplet-routing algorithm or with the actuation sequence. We demonstrate these attacks using a digital microfluidic synthesis simulator. The results show that the attacks are easy to implement and hard to detect. Therefore, this work highlights the need for effective protections against malicious modifications in DMFBs.

[Ab] Resumo:The proinflammatory cytokine tumor necrosis factor (TNF) orchestrates complex multicellular processes through a wide variety of changes that it induces in cell functions. At various stages of the study of TNF, attention has been drawn to one of three different modes of its action. The work that led to the discovery of this cytokine addressed situations in which it inflicts massive damage to tissues through a mode of action that appeared to be unrestricted. In the years that followed, attention was drawn to the existence of negative feedback mechanisms that do restrict TNF formation and function, and of reciprocal mechanisms for negatively regulating TNF-induced gene activation and of cell death. Most recently, the discovery of the critical role of TNF in chronic inflammatory diseases directed attention to the ability of TNF also to act with no apparent time restriction. Major gaps still remain in our knowledge of the cellular and molecular basis for these three modes of TNF action.

[Ti] Título:Salient Feature of Haptic-Based Guidance of People in Low Visibility Environments Using Hard Reins.

[Ab] Resumo:This paper presents salient features of human-human interaction where one person with limited auditory and visual perception of the environment (a follower) is guided by an agent with full perceptual capabilities (a guider) via a hard rein along a given path. We investigate several salient features of the interaction between the guider and follower such as: 1) the order of an autoregressive (AR) control policy that maps states of the follower to actions of the guider; 2) how the guider may modulate the pulling force in response to the trust level of the follower; and 3) how learning may successively apportion the responsibility of control across different muscles of the guider. Based on experimental systems identification on human demonstrations from ten pairs of naive subjects, we show that guiders tend to adopt a third-order AR predictive control policy and followers tend to adopt second-order reactive control policy. Moreover, the extracted guider's control policy was implemented and validated by human-robot interaction experiments. By modeling the follower's dynamics with a time varying virtual damped inertial system, we found that it is the coefficient of virtual damping which is most sensitive to the trust level of the follower. We used these experimental insights to derive a novel controller that integrates an optimal order control policy with a push/pull force modulator in response to the trust level of the follower monitored using a time varying virtual damped inertial model.
