New records, nomenclatural changes, and taxonomic notes for select North American leaf beetles (Coleoptera: Chrysomelidae)

New records, nomenclatural changes and taxonomic notes are presented for select North American leaf beetles (Coleoptera: Chrysomelidae). The following genera are newly recorded from the United States: Nesaecrepida Blake, 1964; Acallepitrix Bechyne, 1959; Margaridisa Bechyne, 1958; Parchicola Bechyne and Springlova de Bechyne, 1975; (all Galerucinae: Alticini); and Demotina Baly, 1874 (Eumolpinae). The following species are newly recorded from the United States: Neolema dorsalis (Olivier, 1791) (Criocerinae); Charidotella bifossulata Boheman, 1855 (Hispinae: Cassidini); Syphrea flauicollis (Jacoby, 1884) (Galerucinae: Alticini); and Promecosoma inflatum Lefevre, 1877, and Demotina modesta Baly, 1874 (Eumolpinae). The following new synonymies are proposed: Deloyala clauata, var. diuersicollis Schaeffer, 1925, transferred from synonymy with Plagiometriona clauata (Fabricius, 1798) to synonymy withP. clauata testudinaria (Boheman, 1855); Chrysomela hybrida Say, 1824, downgraded from subspecies of Calligrapha lunata (Fabricius, 1787) to full synonym of CaZZigrapha lunata (Fabricius); Chrysomela casta Rogers, 1856, downgraded from subspecies of Zygogramma suturalis (Fabricius, 1775) to full synonym of Zygogrammasuturalis (Fabricius); Trirhabdagurneyi Blake, 1951, downgraded to synonym of Trirhabda caduca Horn, 1893; Scelida mimula Wilcox, 1965, downgraded to synonym of Scelida nigricornis (Jacoby, 1888); Exoracalifornica Wilcox, 1953, downgraded to synonym of Pte leon breuicornis (Jacoby, 1887); alaeothonaarizonensis Blake, 1950, downgraded to synonym ofLupraea discrepans (Schaeffer, 1932); Haltica nigritula Linell, 1898, downgraded to synonym of Nesaecrepida asphalt ina (Suffrian, 1868); Cryptocephalus reinhardi Sundman, 1965, downgraded to synonym of Cryptocephalus nwtabilis Melsheimer, 1847. The tribes Chalepini Wiese, 1910, and Uroplatini Weise, 1910 (Hispinae), are synonymized, and both of these family-group names are recognized as nomina protecta. The family-group name Octotomites Chapuis, 1875, is recognized as a nomen oblitum. Coptocycla testudinaria Boheman, 1855, is downgraded from specific status to a subspecies of Plagiometriona clauata (Fabricius, 1798); Cassida bicolor (Fabricius, 1798) is recognized as a valid subspecies of Charidotellasexpunctata (Fabricius). The genus Hemiphrynus Horn, 1889, is removed from synonymy with Phrynocepha and reinstated as a valid genus; Rhabdopterus weisei (Schaeffer, 1920) is removed from synonymy with Rhabdopterus praetextus (Say) and reinstated as a valid species. The following new combinations are proposed: Synetocephalus wallacei (Wilcox, 1965), transferred from Pseudoluperus; Nesaecrepida infuscata (Schaeffer, 1906), transferred from Monomacra; Acallepitrix nitens (Horn, 1889), transferred from Epitrix; Margaridisa atriuentris (Melsheimer, 1847), transferred from Hornaltica; Parchicola iris (Olivier, 1808) and P. tibialis (Olivier, 1808), transferred from Monomacra; and Coleothorpa panochensis (Gilbert, 1981), transferred from Coscinoptera; Promecosoma arizonae (Crotch, 1873), transferred from Metaxyonycha; Tymnes chrysis (Olivier, 1808), T. oregonensis (Crotch, 1873), and T. thaleia (Blake, 1977), transferred from Colaspis. The following new replacement name is proposed: Triarius nigroflaulls, for Luperodes flauoniger Blake, 1942 (not Laboissiere, 1925). The identities of Griburius equestris (Olivier, 1808) and G. laruatlls (Newman, 1840) are discussed

Scholar, Father, and Friend: A Tribute to Professor Justice T. Modibo Ocran

Last November, the Akron community lost a dear friend. For twenty years, he was a faculty member at the University of Akron School of Law, teaching students the intricacies of international and corporate law. His name was Tawia Modibo Ocran, and he was one of the smartest men I have ever met. Born and educated in Ghana, Professor Ocran brought to the classroom a unique perspective; he inspired generations of students with his real-life experiences and understanding of international global issues. He had an impressive, detailed knowledge of international issues and never ceased to amaze me with his ability to humanize those issues. He was an honest intellectual with experiences that gave him the unique ability to teach the law from a humanitarian perspective, a perspective which served his students well and made him one of the most fascinating faculty members ever to have taught international issues at Akron

The non-existence of “inference claims”

Some believe that all arguments make an implicit “inference claim” that the conclusion is inferable from the premises (e.g., Bermejo-Luque, Grennan, the Groarkes, Hitchcock, Scriven). I try to show that this is confused. An act of arguing arises because an inference can be attributed to us, not a meta-level “inference claim” that would make the argument self-referential and regressive. I develop six (other) possible explanations of the popularity of the doctrine that similarly identify confusions

An Algorithm for the Computer Evaluation of Quantitative Laboratory Unknowns Based on Accuracy and Precision

Author Institution: Departments of Chemistry, University of Iowa and Miami UniversityAn algorithm for evaluating student laboratory results is presented in which both proximity to the true result (accuracy) and the reproducibility of these results (preeision) can be evaluated. The usefulness of such a scoring device and its pedagogical advantages are presented. The results are described in terms of a computer program LAB GRADE which is available from the authors upon request

Dynamo action in the ABC flows using symmetries

This is an Accepted Manuscript of an article published by Taylor & Francis in Geophysical and Astrophysical Fluid Dynamics, Volume 108, Issue 1, 2014 available online 25 Sep 2013: http://wwww.tandfonline.com/10.1080/03091929.2013.832762.This paper concerns kinematic dynamo action by the 1:1:1 ABC flow, in the highly conducting limit of large magnetic Reynolds number Rm. The flow possesses 24 symmetries, with a symmetry group isomorphic to the group O24 of orientation preserving transformations of a cube. This can be exploited to break up the linear eigenvalue problem into five distinct symmetry classes, or irreducible representations, which we label I–V. The paper discusses how to reduce the scale of the numerical problem to a subset of Fourier modes for a magnetic field in each representation, which then may be solved independently to obtain distinct branches of eigenvalues and magnetic field eigenfunctions. Two numerical methods are employed: the first is to time step a magnetic field in a given symmetry class and obtain the growth rate and frequency by measuring the magnetic energy as a function of time. The second method involves a more direct determination of the eigenvalue using the eigenvalue solver ARPACK for sparse matrix systems, which employs an implicitly restarted Arnoldi method. The two methods are checked against each other, and compared for efficiency and reliability. Eigenvalue branches for each symmetry class are obtained for magnetic Reynolds numbers Rm up to 104 together with spectra and magnetic field visualisations. A sequence of branches emerges as Rm increases and the magnetic field structures in the different branches are discussed and compared. In a parallel development,results are presented for the corresponding fluid stability problem as a function of the Reynolds number Re.Leverhulme Trus

A Review of the Image Dissector Meteorological Cameras and a View of Their Future

During the Fourth Space Conference, a paper was presented entitled The Image Dissector Camera, A new Approach to Spacecraft Sensors . This is a continuation of that paper. Two daylight cloud cover cameras were discussed in the earlier paper. They were the Applications Technology Satellite III Image Dissector Camera (ATS III IDC) and the Nimbus Image Dissector Camera System (NIMBUS IDCS). Since the ATS III IDC was initially activated in orbit on November 7, 1967, it has sent back to earth more than 1300 cloud cover pictures with near full earth disk coverage per picture. The first Nimbus IDCS flew aboard the illfated Nimbus B which had to be destroyed immediately following booster lift-off, but launch of the backup camera aboard Nimbus B-2 is scheduled within a few weeks. Development studies are presently being funded by NASA Goddard Space Flight Center on two other image dissector camera applications. The first is a 5000 TV line camera that is scheduled to be flown aboard ATS-F. The major objective of this high resolution system is to supply cloud photographs of the full earth disk from which cloud motion studies can be made. The second study involves a three aperture image dissector which is being developed as the sensor for e. multi-spectral camera for earth resources applications. The resolution capability of this system is 2600 TV lines

Two-Stream Transformer Architecture for Long Video Understanding

Pure vision transformer architectures are highly effective for short video classification and action recognition tasks. However, due to the quadratic complexity of self attention and lack of inductive bias, transformers are resource intensive and suffer from data inefficiencies. Long form video understanding tasks amplify data and memory efficiency problems in transformers making current approaches unfeasible to implement on data or memory restricted domains. This paper introduces an efficient Spatio-Temporal Attention Network (STAN) which uses a two-stream transformer architecture to model dependencies between static image features and temporal contextual features. Our proposed approach can classify videos up to two minutes in length on a single GPU, is data efficient, and achieves SOTA performance on several long video understanding tasks
