Investigating perceptual and cognitive abilities of zoo animals might help to improve their husbandry and enrich their daily life with new stimuli. Developing new environmental enrichment programs and devices is hence necessary to promote species-specific behaviours that need to be maintained in controlled environments. As far as we are aware, no study has ever tested the potential benefits of motion illusions as visual enrichment for zoo animals. Starting from a recent study showing that domestic cats are spontaneously attracted by a (...) well-known motion illusion, the Rotating Snake (RS) illusion, we studied whether this illusion could be used as a visual enrichment for big cats. We observed the spontaneous behaviour of three lionesses when three different visual stimuli were placed in their environment: the RS illusion and two control stimuli. The study involved two different periods: the baseline and the RS period, in which the visual stimuli were provided to the lionesses. To assess whether the lionesses were specifically attracted by the RS illusion, we collected data on the number of interactions with the stimuli, as well as on the total time spent interacting with them. To investigate the effect of the illusion on the animals’ welfare, individual and social behaviours were studied and compared between the two periods. The results showed that two lionesses out of three interacted more with the RS stimulus than with the two control stimuli. The fact that the lionesses seemed to be more inclined to interact with the RS stimulus indirectly suggests the intriguing possibility that they were attracted by the illusory motion. Moreover, behavioural changes between the two periods were reported for one of the lionesses, highlighting a reduction in self-directed behaviours and an increase in attentive behaviours, suggesting positive welfare implications. Thus, behavioural observations made before and during the presentation of the stimuli showed that our visual enrichment actually provided positive effects in lionesses. These results call for the development of future studies on the use of visual illusions in the enrichment programs of zoo animals. (shrink)

Can static pictures depict motion and temporal properties? This is an open question that is becoming increasingly discussed in both aesthetics and the philosophy of mind. Theorists working on this issue have mainly focused on static pictures of dynamic scenes and streaky images – such as futurists’ paintings or long-exposure photographs. And yet, we could ask: if there is some success in creating an illusory impression of movement in a static image - as is the case in optical illusions of (...) movement, such as Bridget Riley’s Fall (1963: Tate, London), or Kitaoka’s Rotating Snakes Illusion - is this to say that such static images depict movement? As far as I know, no one working on the depiction of motion has specifically and systematically tackled motion-based illusions nor tried to answer this question. This paper considers two cases of optical illusions of movement and concludes that one of them is involved in the depiction of movement. While the declared goal of my analysis is to answer a quite circumscribed question, it is also the occasion to tackle motion-based illusions tout court - to account for the complex visual experiences they elicit and related phenomenology. Moreover, this account has interesting consequences for theorizing depiction and pictorial experience in general. In particular, it constitutes a counterexample to resemblance theories of depiction.

Previous research found that application of eyeshadow on the upper eyelids induces overestimation of eye size. The present study examined whether this eyeshadow illusion is dependent on or independent of viewpoint. We created a three-dimensional model of a female face and manipulated the presence/absence of eyeshadow and face orientation around the axis of yaw (Experiment 1) or pitch (Experiment 2) rotation. Using the staircase method, we measured perceived eye size for each face stimulus. Results showed that the eyeshadow (...) class='Hi'>illusion occurred regardless of face orientation around axes of both yaw and pitch rotations. Crucially, the illusion’s magnitude did not vary across face orientations; lack of interaction between the illusion’s magnitude and face orientation was confirmed by small values of Bayes factors. These findings ruled out the hypothesis that eyeshadow serves as a depth cue and leads to overestimation of eye size due to size-distance scaling. Alternatively, the present findings suggest that the eyeshadow illusion can be well explained by the assimilation between the eyes and eyeshadow, which also facilitates assimilation between the eyes and eyebrows. Practical implications and the present findings’ generalizability are also discussed. (shrink)

The theory of relativity is often regarded as inhospitable to the idea that there is an objective passage of time in the world. In light of this, many philosophers and physicists embrace a “block universe” view, according to which change and temporal passage are merely a subjective appearance or illusion. My aim in this paper is to argue against such a view, and show that we can make sense of an objective passage of time in the setting of relativity (...) theory by abandoning the assumption that the now must be global, and re-conceiving temporal passage as a purely local phenomenon. Various versions of local becoming have been proposed in the literature. Here I focus on the causal diamond theory proposed by Steven F. Savitt and Richard Arthur, which models the now in terms of a local structure called a causal diamond. After defending the reality of temporal passage and exploring its compatibility with relativity theory, I show how the causal diamond approach can be used to counter the argument for the ideality of time due to Kurt Gödel, based on his “rotating universe” solution to the Einstein field equations. I defend the second component of his argument, the modal step, against the consensus view that finds it wanting, and reject the first step, showing that the Gödel universe is compatible with an objective passage of time as long as the latter is construed locally, along the lines of the causal diamond approach.

This paper aims at giving a brief historical survey of the growth and development of the meaning attributed by the ancient Indians to the term maya. In studying this term we must not lose sight of the fact that it is very often used in various texts without any bearing upon the great problem of the,reality' of the phenomenal world as compared with brahman. In a large number of texts originating in pre-or non-Vedantic circles the word occurs in a great (...) variety of connotations : « power, wisdom, subtle device », and, especially, « incomprehensible power enabling its possessor to create something » ascribed to mighty beings. In the Vedic period there is no basis for any conception of the unreality of the phenomenal world in the use of the term. It does not mean « chimera, illusion, fascination, delusion, fata morgana, etc. ». It refers to a reality of an artificial or misleading character, to phenomena produced by a special ability or imagination ; it can often be translated by a locution beginning with pseudo —, or by the Engl. craft in one of its connotations. It can also mean « fraud, deception ». Philosophers often referred to these common meanings of the word in discussing the,relation' of brahman and the phenomena which essentially are brahman. Svet. Up. 4, 9 and 10 nature is called maya : in this upanûad the germs from which the various views or doctrines of the generations to come were to develop had already reached the first stage of growth without differentiating in any considerable degree. Here maya does not express the unreality of the world, but the impossibility of man's understanding its character and the power of its creator. Nor does the Bhagavadgita question the reality of the world either. Deussen and other scholars were wrong in following Sahara's school of thought which interpreted these texts from its own particular point of view. In the history of Indian thought Buddhism is of outstanding importance. According to the ancient Buddhists the world and the individuals are real, but unstable, of a comparatively insignificant,metaphysical dignity'. The Madhyamika's and Nagarjima's relativistic school prepare the way for the idealistic Vijnanavadins who, founding their ontology on the psychology of yoga, hold the view that only vijnana « mere consciousness » exists. Any pretended,reality' outside this reality is to be regarded as dependent on a wrong interpretation of our inner experiences. The,causally dependent aspect', a determined,form of reality' reflects the,absolute aspect'; the lower constructed aspect' or,wrong ideation', the sphere of the concrete phenomena, however, is to be compared to a snake the presence of which we incorrectly assume when, at dusk, we find a cable.In this connection the term maya is also used : a rope may appear in the shape of a snake, or a maya in the shape of a man and other objects which do not really exist in themselves. This maya is void, non-substantial; in the same way the, wrong or constructive ideation' which appears in the, aspect of subject and object' is called non-substantial. In the process by which the reality of consciousness is transformed into the aspect of wrong ideation maya plays an important rôle : it is the power or factor producing the differentiation of the homogeneous consciousness which results in the pseudo-existence of the phenomenal world. Gaudapada, the earliest exponent of the view of pure non-duality writing at a time when the influence of these idealistic Buddhists was predominant, availed himself of the results of their speculative endeavour. On the other hand he made sure of the sanction of the traditional brahminical circles by expounding his views in the form of an expatiation on the Mandukya. Upanmd. The universum, he holds, is like a dream, like a maya ; « it is not actually so ». All phenomenal beings are dreamlike projections of the Divine Self, which is by its very maya able to make itself assume this projected form. But in his book maya also serves to indicate that any relation at all between the world and the Ultimate cannot be rationally sustained, for this,relation' is inexplicable. Maya, inherent to brahman is the condition underlying the,Origin', the pseudo-existence of this world ; but our lack of understanding is also maya. Our empirical knowledge, which makes us believe that things come into being is would-be knowledge. Maya is the hypothesis needed to express in a formula that the diversity of the phenomenal world is neither identical with atman-brahman nor existing by itself. Sawkara likewise regards the world as,pseudo' ; but in contradistinction to Gaudapada who focusses attention on the maya formula and the character of the phenomena, he emphasizes the sole reality of brahman, avoiding any suggestion as to the world's being void, non-being or unsubstantial. This formulation holds good from the higher point of view, viz. that of the supreme reality, into which empirical knowledge cannot penetrate. For practical purposes the world may be considered as really existing. The ignorance which conceals our true character from us and makes us perceive a world which from the standpoint of the Supreme does not exist is maya. Maya hides the reality and projects a pseudo-reality. It is undefinable and inexplicable ; it is neither being nor non-being. Maya is the postulate needed to account for the phenomenon called universe, for the existence of the diversity, though it is only the One which exists. Finally the maya theories of Saktas and Visnuite schools are briefly discussed. According to the former mayasakti is the power of the Supreme to veil itself without ceasing to be what it is ; they emphasize the point of view that « this all is brahman », accusing Sankara of admitting a principle beside brahman. Ramanuja who basing himself on the conviction that Brahman in the first place is God, defends the thesis that the world and the souls are real, and attacks Sankara's maya theory ; according to this great exponent of Visnuite thought maya symbolizes the wonderful and miraculous in God's creation and creative power.

In lieu of an abstract, here is a brief excerpt of the content:Suñña at the Bone:Emily Dickinson’s Theravadin RomanticismAdam KatzA narrow Fellow in the GrassOccasionally rides—You may have met him? Did you notHis notice instant is—The Grass divides as with a Comb—A spotted Shaft is seen,And then it closes at your FeetAnd opens further on—He likes a Boggy Acre—A Floor too cool for Corn—But when a Boy and BarefootI more than once at NoonHave passed I thought a Whip LashUnbraiding in (...) the SunWhen stooping to secure itIt wrinkled And was gone—Several of Nature’s PeopleI know and they know meI feel for them a transportOf CordialityBut never met this FellowAttended or aloneWithout a tighter BreathingAnd Zero at the Bone.1Via the Arabic word cipher, the English word “zero” comes straight from the Sanskrit word shunya (empty). In Pali, the early Buddhist liturgical language, it is suñña. This poem’s story recalls the common Buddhist simile where a rope is mistaken for a snake in the dim light. There is nothing in the rope that should be feared as a snake, and likewise there is ultimately nothing in the five aggregates—basically, everything—that [End Page 111] can be regarded as atman (soul, self). So the aggregates are empty of self: anatta, in Pali. This is the doctrine of emptiness. Fallaciously imputing selfhood to the inherently selfless flux of the aggregates is a major source of suffering, so realizing emptiness brings liberation, just as investigating the rope and finding it empty of snakehood liberates one from fright.Recognizing that the rope is a rope and not a snake is a simile for realizing emptiness. Likewise, in the poem, recognizing that the snake is a snake and not a “Whip Lash / Unbraiding in the Sun” catapults the speaker into a sublime experience of “Zero at the Bone.” This last line may be a metaphor for being chilled to the bone, but the absence of a subject for zero to modify and the sonic and aesthetic overload in an otherwise mostly matter-of-fact nature poem suggest that the sudden recognition of the snake scares us out of ourselves, empties us out, providing a Romantic corollary for Buddhist emptiness.In the Buddhist simile and in the poem, the correction of faulty recognition precipitates the realization of emptiness. But in the simile, what is primarily important is that the rope is recognized as not a snake. One Tibetan text says that substantial progress can be made by, as it were, mistaking the rope for a vine, just so the scary snake perception is cleared away.2 A slightly later Tibetan text says that, simile aside, recognizing that the rope is not a snake and not even a vine but precisely a rope is merely a matter of “conventional valid cognition,” which stops far short of liberating insight into the selflessness of phenomena as such.3 Believing the rope really is a rope is the same as, in the simile, mistaking the rope for a snake, because in both cases it is a matter of perceiving substantiality where there is impermanence. By contrast, Dickinson’s poem emphasizes neither clearing up a particularly pernicious and persistent misconception about existence nor replacing this misconception with complete insight; rather, the poem emphasizes “conventional valid cognition” itself as a vehicle for sublime transcendence. The ecstatic experience of “Zero at the Bone” requires that the snake be accurately recognized as a snake.This “conventional valid cognition” is technically compatible with complete insight into the selflessness of phenomena as such, and it is certainly possible that the speaker experiences zeroness due to an optical illusion or hallucination or dream rather than recognizing a real snake, but the poem does not highlight either of these possibilities. It emphasizes recognitional accuracy, and being thrown from the quotidian as a result. This is quite different from the lesson of the Buddhist simile, where, again, the emphasis is on what is not there, specifically selfhood, rather than on what is there in its precise distinctness from other things. In this regard the poem is, however, eminently compatible... (shrink)

In the Philosophical Investigations §242, Wittgenstein asserts paradoxically that objectivity is not lost even though communication requires the interplay of agreement in definitions and agreement in judgments. Although Wittgenstein does not claim that objectivity is only determined by this interplay, the objective status of logic initially appears to have disappeared. Wittgenstein here foresees the criticism launched by Kripke that objectivity has been replaced by inter-subjectivity. However, he retorts that the only aspect of objectivity that has vanished is the illusion (...) of any access to an absolute truth independent of language-use. In a transcendental rotation reminiscent of Kant, Wittgenstein maintains that when the notion of a direct trajectory between human consciousness and truth is relinquished, objectivity of any kind relies on rules that language-use generates in the play of a language-game. Wittgenstein grounds objectivity in judgment, and thereby subjects logic to the possibility of communication. (shrink)

Snake venoms are recognized here as a grossly under‐explored resource in pharmacological prospecting. Discoveries in snake systematics demonstrate that former taxonomic bias in research has led to the neglect of thousands of species of potential medical use. Recent discoveries reveal an unexpectedly vast degree of variation in venom composition among snakes, from different species down to litter mates. The molecular mechanisms underlying this diversity are only beginning to be understood. However, the enormous potential that this resource represents for pharmacological (...) prospecting is clear. New high‐throughput screening systems offer greatly increased speed and efficiency in identifying and extracting therapeutically useful molecules. At the same time a global biodiversity crisis is threatening the very snake populations on which hopes for new venom‐derived medications depend. Biomedical researchers, pharmacologists, clinicians, herpetologists, and conservation biologists must combine their efforts if the full potential of snake venom‐derived medications is to be realized.

This study examines the spontaneous use of embodied egocentric transformation in understanding false beliefs in the minds of others. EET involves the participants mentally transforming or rotating themselves into the orientation of an agent when trying to adopt his or her visuospatial perspective. We argue that psychological perspective taking such as false belief reasoning may also involve EET because of what has been widely reported in the embodied cognition literature, showing that our processing of abstract, propositional information is often (...) grounded in concrete bodily sensations which are not apparently linked to higher cognition. In Experiment 1, an agent placed a ball into one of two boxes and left. The ball then rolled out and moved either into the other box or back into the original one. The participants were to decide from which box they themselves or the agent would try to recover the ball. Results showed that false belief performance was affected by increased orientation disparity between the participants and the agent, suggesting involvement of embodied transformation. In Experiment 2, false belief was similarly induced and the participants were to decide if the agent would try to recover the ball in one specific box. Orientation disparity was again found to affect false belief performance. The present results extend previous findings on EET in visuospatial perspective taking and suggest that false belief reasoning, which is a kind of psychological perspective taking, can also involve embodied rotation, consistent with the embodied cognition view.

In this book Daniel Wegner offers a novel understanding of the relation of consciousness, the will, and our intentional and voluntary actions. Wegner claims that our experience and common sense view according to which we can influence our behavior roughly the way we experience that we do it is an illusion.

Determining how we use our body to support cognition represents an important part of understanding the embodied and embedded nature of cognition. In the present investigation, we pursue this question in the context of a common perceptual task. Specifically, we report a series of experiments investigating head tilt (i.e., external normalization) as a strategy in letter naming and reading stimuli that are upright or rotated. We demonstrate that the frequency of this natural behavior is modulated by the cost of stimulus (...) rotation on performance. In addition, we demonstrate that external normalization can benefit performance. All of the results are consistent with the notion that external normalization represents a form of cognitive offloading and that effort is an important factor in the decision to adopt an internal or external strategy.

Abstract The aim of this paper is to attain a philosophical evaluation of the ideas of the French author Maurice Bucaille. Bucaille formulated an influential discourse regarding the divinity of the Qur’an, which he tried to demonstrate through a comparison of some of its verses with what he defined as scientific data. With his works, which encompass a criticism of the Bible and a defense of creationism, Bucaille furthered the idea that Islam is in harmony with natural sciences, and ensured (...) himself long-lasting fame in the Muslim world. Such ideas have found numerous followers and the description of the “scientific miracles” of the Qur’an has turned into a popular genre. Several attempts have been made to criticize Bucaille about specific positions he holds. The thesis I develop here is that, even if Bucaille's work cannot be easily dismissed, a severe methodological shortcoming emerges through the analysis of the logic behind his claims regarding miraculous and supernatural events. Current attempts at defending the harmony between Islam and science should therefore credit Bucaille, but at the same time, be aware of the risk of inheriting his methodological flaws. In the first section, I briefly recall the works of Bucaille and his contribution to the debate on the harmony between Islam and science. In the second section, I reconstruct Bucaille's view of science and his analysis of the sacred scriptures. In the third section, I investigate how Bucaille characterizes the concept of supernatural. In the fourth section, I put forth a general evaluation of his reasoning. (shrink)

The rotating spot method of timing subjective events involves the subject’s watching a rotating spot on a computer and reporting the position of the spot at the instant when the subjective event of interest occurs. We conducted an experiment to investigate factors that may impact on the results produced by this method, using the subject’s perception of when they made a simple finger movement as the subjective event to be timed. Seven aspects of the rotating spot method (...) were investigated, using a factorial experiment. Four of these aspects altered the physical characteristics of the computer generated spot or clock face and the remaining three altered the instructions given to the participant. We found compelling evidence that one factor, whether the subject was instructed to report the instant when the finger movement was initiated or the instant when it was completed, resulted in a systematic shift in the response. Evidence that three other factors affect the observed variability in the response was also found. In addition, we observed that there are substantial systematic differences in the responses made by different subjects. We discuss the implications of our findings and make recommendations about the optimal way of conducting future experiments using the rotating spot method. Our overall conclusion is that our results strongly validate the rotating spot method of timing at least the studied variety of subjective event. (shrink)

This paper examines the first reptile house at the Zoological Gardens in London as a novel site for the production and consumption of knowledge about snakes, stressing the significance of architectural and material limitations on both snakes and humans. Snakes were familiar and ambiguous, present at every level of British society through the reading of Scripture and as recurrent characters in imperial print culture. For all that snakes engendered feelings of disgust as the most distinctive representatives (...) of a lowly class of animals, they exerted an equivalent fascination over diverse publics spanning the social spectrum. Building on work showing a consideration for the multi-sensory nature of visits to menageries, this paper considers animal display beyond the visual. It explores the emotional economy of encountering snakes in person and the bodily phenomena this engendered. Vicarious visits were offered up to readers of periodicals and newspapers and the reptile house was harnessed as a controversial pedagogical resource for teaching moral, as well as scientific, lessons.

In this article, the rotational invariance of entangled quantum states is investigated as a possible cause of the Pauli exclusion principle. First, it is shown that a certain class of rotationally invariant states can only occur in pairs. This is referred to as the coupling principle. This in turn suggests a natural classification of quantum systems into those containing coupled states and those that do not. Surprisingly, it would seem that Fermi–Dirac statistics follows as a consequence of this coupling while (...) the Bose–Einstein follows by breaking it. In Sec. 5, the above approach is related to Pauli's original spin-statistics theorem and finally in the last two sections, a theoretical justification, based on Clebsch–Gordan coefficients and the experimental evidence respectively, is presented.

The proposal to create a chamber selected by sortition would extend this democratic procedure into the legislative branch of government. However, there are good reasons to believe that, as currently conceived by John Gastil and Erik Olin Wright, the proposal will fail to realize sufficiently two fundamental democratic goods, namely, political equality and deliberative reasoning. It is argued through analysis of its historic and contemporary application that sortition must be combined with other institutional devices, in particular, rotation of membership and (...) limited mandate, in order to be democratically effective and to realize political equality and deliberative reasoning. An alternative proposal for a responsive sortition legislature is presented as more realistic and utopian: one that increases substantially the number of members, makes more extensive use of internal sortition and rotation, and recognizes the importance of establishing limited mandates.

In “Sideways Music”, Ned Markosian uses aesthetic intuitions about temporally-rotated music to argue that the metaphysics of time is different from the metaphysics of space. In response, I use aesthetic intuitions about spatially-rotated paintings to pose a dilemma for Markosian’s argument: either he accepts the intuitions about spatially-rotated paintings, in which case he must give up on some assumptions in his argument, or he rejects intuitions about spatially-rotated paintings, in which case an analogous response can be given regarding intuitions about (...) temporally-rotated music. That is, if Markosian wants to hold on to the assumptions that underwrite his argument, then he thereby offers his opponent the resources with which to resist his conclusion. As such, Markosian’s argument cannot offer a new independent consideration for adjudicating the metaphysical debate between the Dynamic Theorist and the Spacetime Theorist. [Unpublishable 2019].

Motor imagery provides a direct insight into action representations. The aim of the present study was to investigate the level of impairment of action monitoring in schizophrenia by evaluating the performance of schizophrenic patients on mental rotation tasks. We raised the following questions: Are schizophrenic patients impaired in motor imagery both at the explicit and at the implicit level? Are body parts more difficult for them to mentally rotate than objects? Is there any link between the performance and the hallucinating (...) symptom profile? The schizophrenic patients displayed the same pattern of performance as the control subjects . More particularly, schizophrenic patients’ reaction time varied as a function of the angular disparity of the stimuli. On the other hand, they were significantly slower and less accurate. Interestingly, patients suffering from hallucinations made significantly more errors than non-hallucinatory patients. We discussed these latter results in terms of deficit of the forward model. We emphasized the necessity to distinguish different levels of action, more or less impaired in schizophrenia. (shrink)

The rotating discs argument against perdurantism has been mostly discussed by metaphysicians, though the argument of course appeals to ideas from classical mechanics, especially about rotation. In contrast, I assess the RDA from the perspective of the philosophy of physics. I argue for three main conclusions. The first conclusion is that the RDA can be formulated more strongly than is usually recognized: it is not necessary to ‘imagine away’ the dynamical effects of rotation. The second is that in general (...) relativity, the RDA fails because of frame-dragging. The third conclusion is that even setting aside general relativity, the strong formulation of the RDA can after all be defeated, namely, by the perdurantist taking objects in classical mechanics to have only temporally extended temporal parts, which immediately blocks the RDA. Admittedly, this version of perdurantism defines persistence in a weaker sense of ‘definition’ than pointilliste versions that aim to define persistence assuming only instantaneous temporal parts. But I argue that temporally extended temporal parts can do the jobs within the endurantism– perdurantism debate that the perdurantist wants temporal parts to do and are supported by both classical and quantum mechanics.

The Zhuangzi begins with Peng, a soaring bird transformed from a bounded fish, which is the first metaphor that points beyond limited standpoints to a higher point of view. The transformation is one-way and symbolizes that there is a higher viewpoint to attain which affords mental freedom and the clarity and scope of great vision. Under the alternate thesis of constant transformation, values and understandings must ceaselessly transform and collapse. All cyclical transformations must collapse into skeptical relativism and confusion. But (...) Peng does not turn back into a fish, and the awakened sage does not fall into a slumber of ignorance and confusion. It is only the thesis of a one-way transformation that leaves the sage in a state of knowledge. (shrink)

We investigate how a uniformly rotating frame is defined as the rest frame of an observer rotating with constant angular velocity Ω around the z axis of an inertial frame. Assuming this frame to be a Lorentz one, we second quantize a free massless scalar field in the rotating frame and obtain that creation-annihilation operators of the field are not the same as those of an inertial frame. This leads to a new vacuum state—a rotating vacuum. (...) After this, introducing an apparatus device coupled linearly with the field, we obtain that there is a strong correlation between the number of Trocheries-Takeno particles (in a given state) obtained via canonical quantization and the response function of the rotating detector. Finally, we analyze polarization effects in circular accelerators in the proper frame of the electron, making a connection with the inertial frame point of view. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

At a recent rally, Donald Trump resumed a habit he had developed during his election-rallies and read out the lyrics to a song. It tells the Aesopian fable of The Farmer and the Snake: A half frozen snake is taken in by a kind-hearted person but bites them the moment it is revived. Trump tells the fable to make a point about Islamic immigrants and undocumented immigrants from Southern and Central America: He claims the immigrants will cause problems and much (...) stricter immigration-policies are needed. I assume that Trump treats the fable as an argumentative device for supporting his stance on immigration. He uses it as a source-analogue both for the conclusion that immigrants will cause problems and for changing the frame in which immigrants and those willing to let them enter are seen. This gives me opportunity to examine the effect fables have as argumentative devices. Fables are a popular and effective choice for political argumentation. They are slimmed down, semi-abstract narratives, well suited for directing the audience's attention to a few properties of an otherwise complex situation. However, this also makes it easy to use them for manipulating an audience into oversimplifying complex contexts and stereotyping human beings. (shrink)

This article puts forward a novel smooth rotated hyperbola model for support vector machine (RHSSVM) for classification. As is well known, the Support vector machine (SVM) is based on Statistical Learning Theory and performs its high precision on data classification. However, the objective function is non-differentiable at the zero point. Therefore the fast algorithms cannot be used to train and test the SVM. To deal with it, the proposed method is based on the approximation property of the hyperbola to its (...) asymptotic lines. Firstly, we describe the development of RHSSVM from the basic linear SVM optimization programming. Then we extend the linear model to non-linear model. We prove the solution of RHSSVM is convergent, unique, and global optimal. We show how RHSSVM can be practically implemented. At last, the theoretical analysis illustrates that compared with other three typical models, the rotated hyperbola model has the least error on approximating the plus function. Meanwhile, computer simulations show that the RHSSVM can reduce the consuming time at most 54.6% and can efficiently handle large scale and high dimensional programming. -/- . (shrink)
