Traversing Tight Tunnels—Implementing an Adaptive Concertina Gait in a Biomimetic Snake Robot Henry C
Earth and Space 2018 158 Traversing Tight Tunnels—Implementing an Adaptive Concertina Gait in a Biomimetic Snake Robot Henry C. Astley1 1Biomimicry Research and Innovation Center, Dept. of Biology and Polymer Science, Univ. of Akron, 235 Carroll St., Akron, OH 44325-3908. E-mail: [email protected] ABSTRACT Snakes move through cluttered habitats and tight spaces with extraordinary ease, and consequently snake robots are a popular design for such situations. The remarkable locomotor performance of snakes is due in part to their diversity of locomotor modes for addressing a range of environmental challenges. Concertina locomotion consists of alternating periods of static anchoring and movement along the snake’s body, and is used to negotiate narrow spaces such as tunnels or bare branches. However, concertina locomotion has rarely been implemented in snake robots. In this paper, the anchor formation process in live snakes during concertina locomotion is quantified and used to implement concertina locomotion in a snake robot, with automatic detection of the width of the tunnel walls to modulate the waveform. This allows effective concertina locomotion in tunnels of unknown width, without prior knowledge of tunnel geometry, expanding the range of gaits in snake robots. INTRODUCTION The elongate, limbless body plan is extremely common throughout nature, in both vertebrate and invertebrates alike (Pechenik, J. A. 2005; Pough, F. H. et al. 2002), and has evolved independently numerous times (Gans, C 1975). Indeed, within lizards (Order Squamata) alone there are over two dozen independent evolutions of limblessness or functional limblessness (Wiens, J. J. et al. 2006). Snakes are by far the most successful limbless taxon, with a near-global distribution, nearly 3000 species, and a wide range of ecological niches and habitats (Pough, F. -

Plato uses the image of a winding labyrinth as a metaphor for the process of philosophical investigation in his dial ogue Euthydemus. His image expresses his belief that, unlike the arts of rhetoric or sophistry —which rely on mere assertion and counter- assertion—philosophy absolutely requires that we retrace our steps in an argument and constantly re-examine our views in order to arrive at knowledge of the true and good. This is what we as students of philosophy aim to do, and this journal is meant to aid in that process. our purpose This journal was created with a threefold purpose. First, to provide undergraduate students with the experience and opportunity of publishing a paper in a philosophical journal.

Hilary Putnam In the last decade enormous progress seems to have been made in the syntactic theory of natural languages, largely as a result of the work of linguists influenced by Noam Chomsky and Zellig Harris. Comparable progress seems not to have been made in the semantic theory of natural languages, and perhaps it is time to ask why this should be the case. Why is the theory of meaning so hard? The meaning of common nouns. To get some idea of the difficulties, let us look at some of the problems that come up in connection with general names. General names are of many kinds. -

Secret US Human Biological Experimentation
Secret US Human Biological Experimentation http://www.apfn.org/apfn/experiment.htm 1931 Dr. Cornelius Rhoads, under the auspices of the Rockefeller Institute for Medical Investigations, infects human subjects with cancer cells. He later goes on to establish the U.S. Army Biological Warfare facilities in Maryland, Utah, and Panama, and is named to the U.S. Atomic Energy Commission. While there, he begins a series of radiation exposure experiments on American soldiers and civilian hospital patients. 1932 The Tuskegee Syphilis Study begins. 200 black men diagnosed with syphilis are never told of their illness, are denied treatment, and instead are used as human guinea pigs in order to follow the progression and symptoms of the disease. They all subsequently die from syphilis, their families never told that they could have been treated. 1935 The Pellagra Incident. After millions of individuals die from Pellagra over a span of two decades, the U.S. Public Health Service finally acts to stem the disease. The director of the agency admits it had known for at least 20 years that Pellagra is caused by a niacin deficiency but failed to act since most of the deaths occured within poverty-striken black populations. 1940 Four hundred prisoners in Chicago are infected with Malaria in order to study the effects of new and experimental drugs to combat the disease. Nazi doctors later on trial at Nuremberg cite this American study to defend their own actions during the Holocaust. 1942 Chemical Warfare Services begins mustard gas experiments on approximately 4,000 servicemen. The experiments continue until 1945 and made use of Seventh Day Adventists who chose to become human guinea pigs rather than serve on active duty. -

Environmental Defense Institute News on Environmental Health and Safety Issues September 2018 Volume 29 Number 9 Continuing Classified Human Subjects Research Involving the Department of Energy Is Worrisome A recent article by the Federation of American Scientists has described the existence of a dozen continuing classified human subjects research involving the Department of Energy and workers at DOE sites. 1 Unclassified human research studies are listed on a DOE database. 2 While there are more protections now than existed decades ago, there are reasons to wonder about the potential for more harm to human subjects than people expect. The Department of Energy’s current list of classified projects obtained by FAS through a Freedom of Information Act request is provided in Table 1.

[The Journal of Philosophical Research XVII (1992): 313-345] Brains in a Vat, Subjectivity, and the Causal Theory of Reference Kirk Ludwig Department of Philosophy University of Florida Gainesville, FL 32611-8545 1. Introduction In the first chapter of Reason, Truth and History,1 Putnam argued that it is not epistemically possible that we are brains in a vat (of a certain sort). If his argument is correct, and can be extended in certain ways, then it seems that we can lay to rest the traditional skeptical worry that most or all of our beliefs about the external world are false. Putnam’s argument has two parts. The first is an argument for a theory of reference2 according to which we cannot refer to an object or a type of object unless we have had a certain sort of causal interaction with it. The second part argues from this theory to the conclusion that we can know that we are not brains in a vat. In this paper I will argue that Putnam’s argument to show that we cannot be brains in a vat is unsuccessful. However, the flaw is not in the argument from the theory of reference to the conclusion 1 Hilary Putnam, Reason, Truth and History, (Cambridge: Harvard University Press, 1979). Henceforth ‘RTH’. The position that Putnam advances in this first chapter is one that in later chapters of RTH he abandons in favor of the position that he calls ‘internal realism’. He represents the arguments he gives in chapter 1 as a problem posed for the ‘external realist’, who assumes the possibility of a God’s eye point of view. -
