Hyperauthorship in Mikhail Bakhtin: The Primary Author and Conceptual Personae
No full textThis article explores the phemenon of hyperauthorship in intellectual writing: a primary author (hyperauthor) creates a number of secondary authors (hypoauthors), and develops possible conceptual systems on their behalf. The case under consideration is Mikhail Bakhtin and his complex relationship with his friends Pavel Medvedev and Valentin Voloshinov, members of the so called "Bakhtin's circle" (in the 1920s) who are credited with authorship of several books which may have been actually written by Bakhtin himself. Still unclear from biographical and historical perspectives, this problem of authentic attribution of Medvedev's and Voloshinov's texts can be clarified in the theoretical framework of "hyperauthorship" and "possibilistic thinking." This article applies Bakhtin's own theory of the "primary author immersed in silence," as well as Deleuze and Guattari's notion of "conceptual personae," to explain this case of "shared," or "transferred" authorship. The figures of Voloshinov and Medvedev, though historically real, may be viewed as Bakhtin's projections of "ideal," or "utopian" Marxism in linguistics and literary theory
Manipulating scattering of ultracold atoms with light-induced dissipation
No full textRecently it has been shown that pairs of atoms can form metastable bonds due to non-conservative forces induced by dissipation [Lemeshko&Weimer, Nature Comm. textbf{4}, 2230 (2013)]. Here we study the dynamics of interaction-induced coherent population trapping -- the process responsible for the formation of dissipatively bound molecules. We derive the effective dissipative potentials induced between ultracold atoms by laser light, and study the time evolution of the scattering states. We demonstrate that binding occurs on short timescales of s, even if the initial kinetic energy of the atoms significantly exceeds the depth of the dissipative potential. Dissipatively-bound molecules with preordained bond lengths and vibrational wavefunctions can be created and detected in current experiments with ultracold atoms
The effect of a nonresonant radiative field on low-energy rotationally inelastic Na⁺ +N₂ collisions
Get PDFWe examine the effects of a linearly polarized nonresonant radiative field on the dynamics of rotationally inelastic Na⁺ +N₂ collisions at eV collision energies. Our treatment is based on the Fraunhofer model of matter wave scattering and its recent extension to collisions in electric fields [M. Lemeshko and B. Friedrich, J. Chem. Phys., in press]. The nonresonant radiative field changes the effective shape of the target molecule by aligning it in the space-fixed frame. This markedly alters the differential and integral scattering cross sections. As the cross sections can be evaluated for a polarization of the radiative field collinear or perpendicular to the relative velocity vector, the model also offers predictions about steric asymmetry of the collisions
What are the implications of Curriculum Learning strategy on IRL methods?: Investigating Inverse Reinforcement Learning from Human Behavior
No full textInverse Reinforcement Learning (IRL) is a subfield of Reinforcement Learning (RL) that focuses on recovering the reward function using expert demonstrations. In the field of IRL, Adversarial IRL (AIRL) is a promising algorithm that is postulated to recover non-linear rewards in environments with unknown dynamics. This study investigates the potential benefits of applying the Curriculum Learning (CL) strategy to the AIRL algorithm. For our experiments, we use a randomized partially observable Markov decision process in the form of a grid-world-like environment. Using only expert demonstrations obtained with an RL algorithm under the true reward function, we train AIRL in a variety of configurations and identify an effective curriculum. Our results show, that a well-constructed curriculum can enhance the performance of AIRL twofold in both key aspects: the speed of convergence and the efficiency of using expert demonstrations. We thus conclude that CL can be a useful addition to an AIRL-based solution.

Collisions of paramagnetic molecules in magnetic fields: An analytic model based on Fraunhofer diffraction of matter waves
Get PDFWe investigate the effects of a magnetic field on the dynamics of rotationally inelastic collisions of open-shell molecules (² Σ, ³Σ, and ²Π) with closed-shell atoms. Our treatment makes use of the Fraunhofer model of matter wave scattering and its recent extension to collisions in electric [M. Lemeshko and B. Friedrich, J. Chem. Phys. 129, 024301 (2008)] and radiative fields [M. Lemeshko and B. Friedrich, Int. J. Mass. Spec. in press (2008)]. A magnetic field aligns the molecule in the space-fixed frame and thereby alters the effective shape of the diffraction target. This significantly affects the differential and integral scattering cross sections. We exemplify our treatment by evaluating the magnetic-field-dependent scattering characteristics of the He – CaH (X² Σ⁺), He – O₂ (X³Σ⁻) and He – OH (X²ΠΩ ) systems at thermal collision energies. Since the cross sections can be obtained fordifferent orientations of the magnetic field with respect to the relative velocity vector, the model also offers predictions about the frontal-versus-lateral steric asymmetry of the collisions. The steric asymmetry is found to be almost negligible for the He – OH system, weak for the He – CaH collisions, and strong for the He – O₂ . While odd ∆M transitions dominate the He – OH
(J = 3/2, f → J′ , e/f ) integral cross sections in a magnetic field parallel to the relative velocity vector, even ∆M transitions prevail in the case of the He – CaH (X²Σ⁺) and He – O₂ (X³Σ⁻) collision systems. For the latter system, the magnetic field opens inelastic channels that are closed in the absence of the field. These involve the transitions N = 1, J = 0 → N′, J′ with J′ = N′
Effect of a magnetic field on molecule–solvent angular momentum transfer
No full textRecently it was shown that a molecule rotating in a quantum solvent can be described in terms of the “angulon” quasiparticle [M. Lemeshko, Phys. Rev. Lett. 118, 095301 (2017)]. Here we extend the angulon theory to the case of molecules possessing an additional spin-1/2 degree of freedom and study the behavior of the system in the presence of a static magnetic field. We show that exchange of angular momentum between the molecule and the solvent can be altered by the field, even though the solvent itself is non-magnetic. In particular, we demonstrate a possibility to control resonant emission of phonons with a given angular momentum using a magnetic field

Muriel Spark as auto-biographer in <i>Curriculum</i> <i>Vitae</i>
Get PDFExamining Muriel Spark's main aims as an auto-biographer in her work Curriculum Vitae brings important resources in the exploration of the genre of autobiographical writing. This with the theoretical engagement, allows consideration of the critical issues surrounding the roles of author and reader in the construction of the literary self. Spark demands the reader participate in the constructon of textual meaning; overturning the conventions of autobiography, satirising its claims to omniscience and highlighting the impossibility of an authentic voice with regard to the self
To Act and Learn: A Bakhtinian Exploration of Action Learning
Get PDFThis paper considers the work of the Russian social philosopher and cultural theorist, Mikhail Mikhailovich Bakhtin as a source of understanding for those involved in action learning. Drawing upon data gathered over two years during the evaluation of 20 action learning sets in the north of England, we will seek to work with the ideas of Bakhtin to consider their value for those involved in action learning. We consider key Bakhtin features such as Making Meaning, Participative Thinking, Theoreticism and Presence, Others and Outsideness, Voices and Carnival to highlight how Bakhtin's can enhance our understanding of the nature of action and learning
Rotation of cold molecular ions inside a Bose-Einstein condensate
No full textWe use recently developed angulon theory [R. Schmidt and M. Lemeshko, Phys. Rev. Lett. 114, 203001 (2015)PRLTAO0031-900710.1103/PhysRevLett.114.203001] to study the rotational spectrum of a cyanide molecular anion immersed into Bose-Einstein condensates of rubidium and strontium. Based on ab initio potential energy surfaces, we provide a detailed study of the rotational Lamb shift and many-body-induced fine structure which arise due to dressing of molecular rotation by a field of phonon excitations. We demonstrate that the magnitude of these effects is large enough in order to be observed in modern experiments on cold molecular ions. Furthermore, we introduce a novel method to construct pseudopotentials starting from the ab initio potential energy surfaces, which provides a means to obtain effective coupling constants for low-energy polaron models
