Period-two cycles in a feed-forward layered neural network model with symmetric sequence processing
The effects of dominant sequential interactions are investigated in an
exactly solvable feed-forward layered neural network model of binary units and
patterns near saturation in which the interaction consists of a Hebbian part
and a symmetric sequential term. Phase diagrams of stationary states are
obtained and a new phase of cyclic correlated states of period two is found for
a weak Hebbian term, independently of the number of condensed patterns .Comment: 8 pages and 5 figure

Twist-2 Generalized TMDs and the Spin/Orbital Structure of the Nucleon
Generalized transverse-momentum dependent parton distributions (GTMDs) encode
the most general parton structure of hadrons. Here we focus on two twist-2
GTMDs which are denoted by and in parts of the literature.
As already shown previously, both GTMDs have a close relation to orbital
angular momentum of partons inside a hadron. However, recently even the mere
existence of and has been doubted. We explain why this
claim does not hold. We support our model-independent considerations by
calculating the two GTMDs in the scalar diquark model and in the quark-target
model, where we also explicitly check the relation to orbital angular momentum.
In addition, we compute and at large transverse momentum in
perturbative Quantum Chromodynamics and show that they are nonzero.Comment: 29 pages, 6 figures; two clarifications and a reference added;

Signifying Nothing?: Martin Ritt\u27s The Sound and the Fury (1959) as Deconstructive Adaptation
This essay defends Martin Ritt\u27s film version of The Sound and the Fury (1959), starring Yul Brynner as a Cajun Jason Compson, traditionally positioned as one of the most ill-conceived film adaptations ever made, by highlighting how an academic modernist reading of the works of William Faulkner overwrites the intriguing possibilities of melodrama
Max Ophuls
A short biographical piece on filmmaker Max Ophuls, with particular focus on his melodramas made in Hollywood in the late 1940s and early 1950s
New Englanders, Out of Their Minds
By comparing The Witch (2016) to The Shining (Stanley Kubrick, 1980), I argue that Robert Eggers\u27 new film contests Perry Miller\u27s sympathetic reading of the Puritans offered as the formation of American Studies, returning us to the 19th century critique offered by Nathaniel Hawthorne, particularly in his short story, Young Goodman Brown (1835)
Narrative Delay and the Nature of Love in the Short Film, Come
By showing teenagers falling in love, and then cutting to the loving couple, now elderly, the short film, Come brilliantly uses the excision of the narrative tradition of delay in order to revolutionize the cinema\u27s presentation of love in theoretical synchronicity with Irving Singer\u27s philosophical study, The Nature of Love
Universality of soft and collinear factors in hard-scattering factorization
Universality in QCD factorization of parton densities, fragmentation
functions, and soft factors is endangered by the process dependence of the
directions of Wilson lines in their definitions. We find a choice of directions
that is consistent with factorization and that gives universality between
e^+e^- annihilation, semi-inclusive deep-inelastic scattering, and the
Drell-Yan process. Universality is only modified by a time-reversal
transformation of the soft function and parton densities between Drell-Yan and
the other processes, whose only effect is the known reversal of sign for T-odd
parton densities like the Sivers function. The modifications of the definitions
needed to remove rapidity divergences with light-like Wilson lines do not
affect the results.Comment: 4 pages. Extra references. Text and references as in published

Atomic Animals: Toward the Re-invention of Natural History and Science Filmmaking
This essay explores the use of atomic imagery in natural history films as presented in the United States on The Discovery Channel. Using the methods of nuclear criticism, the article builds a case study of the apocalyptic and militarist metaphors employed by an episode of PaleoWorld devoted to the Stegosaurus and then broadens the scope toward more popular animal filmmaking, in particular, “blue chip” wildlife films such as Lion Battlefield
