As most work on flower foraging focuses on bees, studying Lepidoptera can offer fresh perspectives on how sensory capabilities shape the interaction between flowers and insects. Through a combination of innate preferences and learning, many Lepidoptera persistently visit particular flower species. Butterflies tend to rely on their highly developed sense of colour to locate rewarding flowers, while moths have evolved sophisticated olfactory systems towards the same end. However, these modalities can interact in complex ways; for instance, butterflies’ colour preference can (...) shift depending on olfactory context. The mechanisms by which such cross‐modal interaction occurs are poorly understood, but the mushroom bodies appear to play a central role. Because of the diversity seen within Lepidoptera in terms of their sensory capabilities and the nature of their relationships with flowers, they represent a fruitful avenue for comparative studies to shed light on the co‐evolution of flowers and flower‐visiting insects.

People sometimes persistently pursue hard-to-get targets. Why people pursue such targets is unclear. Here, we hypothesized that choice perseverance, which is the tendency to repeat the same choice independent of the obtained outcomes, leads individuals to repeatedly choose a hard-to-get target, which consequently increases their preference for the target. To investigate this hypothesis, we conducted an online experiment involving an avatar choice task in which the participants repeatedly selected one avatar, and the selected avatar expressed their valence reactions through facial (...) expressions and voice. We defined “hard-to-get” and “easy-to-get” avatars by manipulating the outcome probability such that the hard-to-get avatars rarely provided a positive reaction when selected, while the easy-to-get avatars frequently did. We found that some participants repeatedly selected hard-to-get avatars. Based on a simulation, we found that higher choice perseverance accounted for the pursuit of hard-to-get avatars and that the Pursuit group had significantly higher choice perseverance than the No-pursuit group. Model fitting to the choice data also supported that choice perseverance can account for the pursuit of hard-to-get avatars in the Pursuit group. Moreover, we found that although baseline attractiveness was comparable among all avatars used in the choice task, the attractiveness of the hard-to-get avatars was significantly increased only in the Pursuit group. Taken together, we conclude that people with high choice perseverance pursue hard-to-get targets, rendering such targets more attractive. The tolerance for negative outcomes might be an important factor for succeeding in our lives but sometimes triggers problematic behavior, such as stalking. The present findings may contribute to understanding the psychological mechanisms of passion and perseverance for one’s long-term goals, which are more general than the romantic context imitated in avatar choice.

Previous research in the history of physics has led us to believe that Yoshio Nishina (1890–1951) virtually single‐handedly imported quantum physics into Japan. However, there are first‐hand accounts that Yoshikatsu Sugiura (1895–1960) also played an important role. Sugiura made his name in quantum chemistry with his contribution to the Heitler‐London theory of the chemical bond. Yet, historians of physics have paid scant attention to him. This paper brings forward information on Sugiura from his letters, his scientific papers, and his own (...) recollections until ca. 1930. By examining this material, the present paper studies Sugiura's accomplishments in Europe and his contributions to the development of quantum physics in Japan. We conclude that Sugiura was one of the most important physicists when it comes to the arrival of quantum physics in Japan. In addition, we assess why he has been under‐appreciated in the history of physics in Japan. Our historical study on Sugiura suggests that, in addition to the position Nishina and his students rightfully occupy, there still are important unexplored aspects in the history of Japanese quantum physics.

In his embryological treatise De plastica seminis facultate , Jacob Schegk , professor of philosophy and medicine at the University of Tübingen, developed, through a unique interpretation of the Aristotelian embryology, a theory of the "plastic faculty" , whose origin lay in the Galenic idea of the formative power. The present study analyses the precise nature of Schegk's theory, by setting it in its historical and intellectual context. It will also discuss the hitherto unappreciated Neoplatonic dimension of Schegk's notion of (...) the soul's vehicle. (shrink)

The treatise On Formative Power of Ferrara's emblematic medical humanist, Nicolò Leoniceno , is the one of the first embryological monographs of the Renaissance. It shows, at the same time, the continuity of medieval Arabo-Latin tradition and the new elements brought by Renaissance medical humanism, namely through the use of the ancient Greek commentators of Aristotle like Simplicius. Thus this treatise stands at the crossroad of these two currents. The present study analyses the range of Leoniceno's philosophical discussion, determines its (...) exact sources and brings to light premises for the early modern development of the concept of formative force, which will end up in the theory of "plastic nature" at the heart of the Scientific Revolution.

The idea of a canonical transformation emerged in 1837 in the course of Carl Jacobi's researches in analytical dynamics. To understand Jacobi's moment of discovery it is necessary to examine some background, especially the work of Joseph Lagrange and Siméon Poisson on the variation of arbitrary constants as well as some of the dynamical discoveries of William Rowan Hamilton. Significant figures following Jacobi in the middle of the century were Adolphe Desboves and William Donkin, while the delayed posthumous publication in (...) 1866 of Jacobi's full dynamical corpus was a critical event. François Tisserand's doctoral dissertation of 1868 was devoted primarily to lunar and planetary theory but placed Hamilton–Jacobi mathematical methods at the forefront of the investigation. Henri Poincaré's writings on celestial mechanics in the period 1890–1910 succeeded in making canonical transformations a fundamental part of the dynamical theory. Poincaré offered a mathematical vision of the subject that differed from Jacobi's and would become influential in subsequent research. Two prominent researchers around 1900 were Carl Charlier and Edmund Whittaker, and their books included chapters devoted explicitly to transformation theory. In the first three decades of the twentieth century Hamilton–Jacobi theory in general and canonical transformations in particular would be embraced by a range of researchers in astronomy, physics and mathematics.

The neuromodulatory effects of brain stimulation therapies notably involving repetitive transcranial magnetic stimulation on nocturnal sleep, which is critically disturbed in major depression and other neuropsychiatric disorders, remain largely undetermined. We have previously reported in major depression patients that prefrontal rTMS sessions enhanced their slow wave activity power, but not their sigma power which is related to sleep spindle activity, for electrodes located nearby the stimulation site. In the present study, we focused on measuring the spindle density to investigate cumulative (...) effects of prefrontal rTMS sessions on the sleep spindle activity. Fourteen male inpatients diagnosed with medication-resistant unipolar or bipolar depression were recruited and subjected to 10 daily rTMS sessions targeting the left dorsolateral prefrontal cortex. All-night polysomnography data was acquired at four time points: Adaptation, Baseline, Post-1, and Post-2. Clinical and cognitive evaluations were longitudinally performed at Baseline, Post-1, and Post-2 time points to explore associations with the spindle density changes. The PSG data from 12 of 14 patients was analyzed to identify sleep spindles across the sleep stages II–IV at four electrode sites: F3, F4, P3, and P4. Statistical analysis by two-way ANOVA revealed that spindle density at F3 increased at Post-1 but decreased at Post-2 time points. Moreover, the local and transient increase of spindle density at F3 was associated with the previously reported SWA power increase at F3, possibly reflecting a shared mechanism of thalamocortical synchronization locally enhanced by diurnal prefrontal rTMS sessions. Clinical and cognitive correlations were not observed in this dataset. These findings suggest that diurnal rTMS sessions transiently modulate nocturnal sleep spindle activity at the stimulation site, although clinical and cognitive effects of the local changes warrant further investigation.

Inspired by Christian Platonism as developed in the late fifteenth-century Florentine milieu, the French physician Jean Fernel proposed a particular interpretation of Galen in a medico-philosophical work entitled On the Hidden Causes of Things . With this interpretation, he responded to the serious and urgent need for a reconciliation of the newly reconstituted Galen of Renaissance humanism with Christian faith. The present study examines Fernel's strategy and method in constructing this singular Galenic body of doctrine, special attention being given to (...) the roles attributed to the Creator, the formative force, and the soul. Subsequently, an analysis of the notions of spirit and of its innate heat as indispensable instruments of Fernel's physiology will uncover the very target of his criticism of materialism. (shrink)

One of the most striking features of Giordano Bruno’s philosophy is the marriage of universal animation with atomism. This unusual combination produced an extraordinary image of the universe, which was governed by the World-Soul and its universal intellect along with an infinite number of living atoms or corpuscles, animated by their internal spiritual principle. After examining Bruno’s principal arguments on the World-Soul, universal animation and living atoms or corpuscles, this article explores two possible sources among the works of his near-contemporaries. (...) The first author, Agostino Steuco, tried to reconcile the doctrine of the World-Soul with Christianity, integrating the idea of Anaxagoras on the cosmic mind as the demiurgic agent of the universe. The second figure, Jacob Schegk, further elaborated his unusual atomistic or corpuscular reinterpretation of this Presocratic philosopher’s ideas. (shrink)

This volume brings Bergson's key ideas from Matter and Memory into dialogue with contemporary themes on memory and time in science, across analytic and continental philosophy. Focusing specifically on the application of Bergson's ideas to cognitive science, the circuit between perception and memory receives full explication in 15 different essays. By re-reading Bergson through a cognitive lens, the essays provide a series of alternative analytic interpretations to the standard continental approach to Bergson's oeuvre, without fully discounting either approach. The relevance (...) of philosophies of mind and memory sit alongside the role of a metaphysics of time in exploring connections to psychology, biology, and physics. This eclecticism includes an exciting focus on numerous topics that are not given sufficient attention in extant studies of Bergson, including the precise nature of his ideas on dualism, memory, and ecological theories of perception, especially in relation to his contemporaries. Led by leading Bergson scholars from France and Japan, this book maps the rich terrain of Bergson's contemporary relevance alongside the historical context of his ideas. (shrink)

Organogenesis and metamorphosis require the intricate orchestration of multiple types of cellular interactions and signaling pathways. Glutamate (Glu) is an excitatory extracellular signaling molecule in the nervous system, while Ca2+ is a major intracellular signaling molecule. The first Glu receptors to be cloned are Ca2+‐permeable receptors in mammalian brains. Although recent studies have focused on Glu signaling in synaptic mechanisms of the mammalian central nervous system, it is unclear how this signaling functions in development. Our recent article demonstrated that Ca2+‐permeable (...) AMPA‐type Glu receptors (GluAs) are essential for formation of a photosensitive organ, development of some neurons, and metamorphosis, including tail absorption and body axis rotation, in ascidian embryos. Based on findings in these embryos and mammalian brains, we formed several hypotheses regarding the evolution of GluAs, the non‐synaptic function of Glu, the origin of GluA‐positive neurons, and the neuronal network that controls metamorphosis in ascidians.

Summary The famous Jesuit father Athanasius Kircher (1602?1680) tried to interpret the Creation of the world and to explain the origin of life in the last book of his geocosmic encyclopedia, Mundus subterraneus (Amsterdam, 1664?1665). His interpretation largely depended on the ?concept of seeds? which was derived from the tradition of Renaissance ?chymical? (chemical and alchemical) philosophy. The impact of Paracelsianism on his vision of the world is also undeniable. Through this undertaking, Kircher namely developed a corpuscular theory for the (...) spontaneous generation of living beings. The present study examines this theory and its relationship with Kircher's chymical interpretation of the Creation in order to place it in its own intellectual and historical context and will uncover one of its most important sources.

In lieu of an abstract, here is a brief excerpt of the content:Race, Buddhism, and the Formation of Oriental (Tōyō) Philosophy in Meiji JapanYijiang ZhongIntroduction: Why Race for Philosophy?This paper examines the discursive efforts by Inoue Tetsujirō井上哲次郎, the foremost figure in the establishment of philosophical study in Meiji Japan, to de-Westernize Buddhism for the purpose of redefining the Orient (Tōyō 東洋) and constructing Oriental philosophy in contribution to nation-state building in Japan1. Born in 1855 to a doctor’s family in Kyushu, (...) Inoue studied Confucian classics as well as English and Western thought at a young age before being selected to study at the newly established Tokyo University (Tokyo daigaku 東京大学), which was renamed Imperial University (Teikoku daigaku 帝国大学) in 1886 and then Tokyo Imperial University (Tokyo teikoku daigaku 東京帝国大学) in 1897. Upon graduation, Inoue taught philosophy at the university and co-published the first dictionary of philosophy, Tetsugaku jii (字彙) in 1881. In 1884, Inoue was sent to study philosophy in Europe, and upon returning to Japan in 1890, he became a professor of philosophy at (Tokyo) Imperial University, a position he held until retirement in 1923. Regarded as “the representative philosopher of the Meiji period,”2 Inoue played a major role in adopting and reconfiguring both Western and indigenous discourses and categories in the formulation of Oriental philosophy (Tōyō tetsugaku 東洋哲学), and shaped this new form of philosophical knowledge in the service of a “national morality” (kokumin dōtoku 国民道徳), i.e., the ideological foundation of modern Japanese nation-state building. Key to Inoue’s philosophical thought was the eclectic idea of “phenomenon as essence” (genshō soku jitsuzai ron), or the unity of appearance and substance, which Inoue developed by integrating the Kantian distinction of noumena (thing-in-itself) [End Page 53] and phenomenon, and the Buddhist distinction of discrimination (sabetsu) and equality (byōdō).3In October 1890, Inoue Tetsujirō returned to Japan after six years of study in Germany and took up a professorship of philosophy in the Department of Literature of Tokyo Imperial University, where he lectured from 1891 to 1898 on Indian philosophy and history of Buddhism under the title of “Comparative Religion and Oriental Philosophy.”4 On June 30, 1897, he published a small (123-page) book entitled On the Race of Shakyamuni (Shaka shuzoku ron 釋迦種族論), which included a lecture “What Race was Buddha Shakyamuni?” (Shaka ha ikanaru shuzoku nanoka 釋迦は如何なる種族なのか) given at the Tokyo Academy (Gakushi kaiin 学士会院) on July 7, 1895, and a much longer essay defending his theory of the Buddha’s race developed from the lecture as an attack on Naka Michiyo 那珂通世, who was a professor at Tokyo Higher Normal School engaged in a public debate with Inoue on the issue. In 1902, Inoue went on to publish a biography of the Buddha, Shakyamuni-den 釈迦牟尼伝, demonstrating his persistent interest in the life and identity of the founder of Buddhism. Curiously, while the title “What Race Was the Buddha” appeared in the table of contents of the biography, the essay itself was not included in the book. Then in April 1911, a new version of the biography was published after Inoue and his student Hori Kentoku 堀謙徳 expanded the content and appended seven annotations and bibliographical essays, including one on the racial identity of the Buddha. The revised biography has 465 pages, greatly expanding the 1902 version of 286 pages. This time, not only was the essay “What Race Was the Buddha” not included, but its title did not appear in the table of contents either.Why did Inoue need to talk about race and determine the racial identity of the Buddha when he was lecturing on Oriental philosophy, religion, and national morality? What do the emergence and disappearance of the issue of the Buddha’s racial origin in Inoue’s lectures and publications mean? How did these changes speak of Buddhism, Oriental philosophy, and Japanese philosophy Inoue was constructing? So far, scholars have not raised the question of race, although a growing amount of literature on Inoue from the perspectives of philosophy, intellectual history, and political ideology is surfacing.5 The only study that touched upon Inoue’s essay on the racial identity of the Buddha is Isomae Junichi 磯前順一’s Kindai Nihon no shūkyō gensetsu to sono keifu 近代日本の宗教言説とその系譜 [End Page 54...

We study stable strategy profiles in a pure exchange game of bads, where each player dumps his or her bads such as garbage onto someone else. Hirai et al. (Mathematical Social Sciences 51(2):162–170, 2006) show that cycle dumping, in which each player follows an ordering and dumps his or her bads onto the next player, is a strong Nash equilibrium and that self-disposal is $$\alpha $$ -stable for some initial distributions of bads. In this paper, we show that a (...) strategy profile of bullying, in which all players dump their bads onto a single player, becomes $$\alpha $$ -stable for every exchange game of bads. We also provide a necessary and sufficient condition for a strategy profile to be $$\alpha $$ -stable in an exchange game of bads. In addition, we show that repeating an exchange after the first exchange makes self-disposal stationary. (shrink)

One Seit Platon (mit dem Spott von Diogenes) über Kant ist die Fundamentalfrage "Was ist der Mensch?" bis heute nicht nur von der Philosophie (als regina scientiarum), sondern von der Wissenschaft überhaupt nicht beantwortet. Phänomenologisch hat der Mensch a posteriori physische (somatische), psychische(perceptio, emotio, cognitio), mentale (logische), spirituelle (conscientia, volitio, actio) "Sphären". Ontologisch in Kontext von to ti en einai (Aristoteles) sollte der Mensch a priori ein "Programm" (Information) vor der Kosmogonie haben. Der (Neo‐) Positivismus (z.B. Hume bis Carnap, Russel*; (...) * Nobel Laureate) verwirft Fragen der Metaphysik als Scheinprobleme. Damit bleibt das Menschen‐Wesen in Kontext von Postulaten, wie res cogitans (Descartes), Monaden(Leibniz), "Gott, Freiheit, Unsterblichkeit", Seligkeit und (moralischer) Vollkommenheit (Kant), absoluter Geist (Hegel) in der theologischen Dimension. Antwort könnte eine zukünftige (holistisch‐multidimensionale) philosophische theoretische und Experimentaltheologie (kontrollierbare Beobachtung) durch weitere Forschung geben, in Kontext (bzw. Existenz) von A. Physikotheologie bzw. (a) höhere (als drei) geometrische/physikalische Dimensionen (Hilbert, Riemann /Friedmann, Minkowski, Schmutzer), (b) Paralleluniversen (z.B. L.

Psychotheologie bzw. parapsychische Phänomene (Carrel*, Richet*/France, Rhinne/USA, Vassilev, Bechterew/Russia, etc.). D.
