The Relationship Between North and Middle American \u3ci\u3eStenonema\u3c/i\u3e (Ephemeroptera: Heptageniidae)
Stenonema integrum (McDunnough) is shown to be a junior synonym of S. mexicanum (Ulmer.) n.syn. Subspecific status is delegated to Nearctic and Neotropical populations of this species as S. m. imegrum and S, m. mexicanum, respectively. Newly studied materials from Costa Rica and Belize indicate that adults of the two subspecies may be differentiated by the presence of thoracie pleural stripes in S. m. mexicanum. Consistent differentiating lanai characteristics are not known, A Pleistocene dispersal into Middle America and subsequent vicariance is hypothesized

The Higher Spin/Vector Model Duality
This paper is mainly a review of the dualities between Vasiliev's higher spin
gauge theories in AdS4 and three dimensional large N vector models, with focus
on the holographic calculation of correlation functions of higher spin
currents. We also present some new results in the computation of parity odd
structures in the three point functions in parity violating Vasiliev theories.Comment: 55 pages, 1 figure. Contribution to J. Phys. A special volume on

Mixed-symmetry tensor conserved currents and AdS/CFT correspondence
We present the full list of conserved currents built of two massless spinor
fields in Minkowski space and their derivatives multiplied by Clifford algebra
elements. The currents have particular mixed-symmetry type described by Young
diagrams with one row and one column of arbitrary lengths and heights. Along
with Yukawa-like totally antisymmetric currents the complete set of constructed
currents exactly matches the spectrum of AdS mixed-symmetry fields arising in
the generalized Flato-Fronsdal theorem for two spinor singletons. As a
by-product, we formulate and study general properties of primary fields and
conserved currents of mixed-symmetry type.Comment: 17 pages; v2: typos corrected, clarifications and refs added; v3:

Composite fluxbranes with general intersections
Generalized composite fluxbrane solutions for a wide class of intersection
rules are obtained. The solutions are defined on a manifold which contains a
product of n Ricci-flat spaces M_1 x ... x M_n with 1-dimensional M_1. They are
defined up to a set of functions H_s obeying non-linear differential equations
equivalent to Toda-type equations with certain boundary conditions imposed. A
conjecture on polynomial structure of governing functions H_s for intersections
related to semisimple Lie algebras is suggested. This conjecture is valid for
Lie algebras: A_m, C_{m+1}, m > 0. For simple Lie algebras the powers of
polynomials coincide with the components of the dual Weyl vector in the basis
of simple roots. Explicit formulas for A_1 + ... + A_1 (orthogonal),
"block-ortogonal" and A_2 solutions are obtained. Certain examples of solutions
in D = 11 and D =10 (II A) supergravities (e.g. with A_2 intersection rules)
and Kaluza-Klein dyonic A_2 flux tube, are considered.Comment: 19 pages, Latex, 1 reference (on a pioneering paper of Gibbons and
Wiltshire) and two missing relations are added Published: Class. Quantum

SAURON: An Innovative Look at Early-Type Galaxies
A summary of the SAURON project and its current status is presented. SAURON
is a panoramic integral-field spectrograph designed to study the stellar
kinematics, gaseous kinematics, and stellar populations of spheroids. Here, the
sample of galaxies and its properties are described. The instrument is detailed
and its capabilities illustrated through observational examples. These includes
results on the structure of central stellar disks, the kinematics and
ionization state of gaseous disks, and the stellar populations of galaxies with
decoupled cores.Comment: 10 pages, 6 figures. To appear in "The Dynamics, Structure & History
of Galaxies", eds. G. S. Da Costa & E. M. Sadler (San Francisco: ASP).

Colliding Kaluza-Klein Bubbles
We construct an exact solution describing the collision of two Kaluza-Klein
"bubbles of nothing" in 3+1 dimensions. When the bubbles collide, a curvature
singularity forms which is hidden inside an event horizon. However, unlike the
formation of ordinary black holes, in this case the spacetime resembles the
entire maximally extended Schwarzschild solution. We also point out that there
are inequivalent bubbles that can be constructed from Kerr black holes.Comment: 20 pages, v2: minor error correcte
Beware of Courts Bearing Gifts: Transparency and the Court of Justice of the European Union
This article reconsiders the principle of transparency in the European Union (EU) legal order and takes as its focal point the contribution of the EU Courts as regards the presumptions of non-disclosure of EU documents. The aim is to investigate the role played by the judiciary in relation to a twofold question: How open can the Unionâs decision-making be, and is it possible for citizens to participate in the decision-making process of EU institutions, bodies, offices and agencies? The article argues that accountability deficits in the field of access to documents have been filled, to an extent, by the EU Courtsâ imposition of boundaries on the broad derogations to the right of access to documents. But nevertheless, the article concludes that the establishment through the case law of general presumptions against openness has fundamentally weakened the standards of accountability. Rather regrettably, although the EU legislature set the default position to the widest access to documents, this has been reversed to non-disclosure by the EU judiciary as regards non-legislative documents
Current Methods to Unravel the Functional Properties of Lysosomal Ion Channels and Transporters
open18siA distinct set of channels and transporters regulates the ion fluxes across the lysosomal membrane. Malfunctioning of these transport proteins and the resulting ionic imbalance is involved in various human diseases, such as lysosomal storage disorders, cancer, as well as metabolic and neurodegenerative diseases. As a consequence, these proteins have stimulated strong interest for their suitability as possible drug targets. A detailed functional characterization of many lysosomal channels and transporters is lacking, mainly due to technical difficulties in applying the standard patch-clamp technique to these small intracellular compartments. In this review, we focus on current methods used to unravel the functional properties of lysosomal ion channels and transporters, stressing their advantages and disadvantages and evaluating their fields of applicability.openFesta M.; Minicozzi V.; Boccaccio A.; Lagostena L.; Gradogna A.; Qi T.; Costa A.; Larisch N.; Hamamoto S.; Pedrazzini E.; Milenkovic S.; Scholz-Starke J.; Ceccarelli M.; Vitale A.; Dietrich P.; Uozumi N.; Gambale F.; Carpaneto A.Festa, M.; Minicozzi, V.; Boccaccio, A.; Lagostena, L.; Gradogna, A.; Qi, T.; Costa, A.; Larisch, N.; Hamamoto, S.; Pedrazzini, E.; Milenkovic, S.; Scholz-Starke, J.; Ceccarelli, M.; Vitale, A.; Dietrich, P.; Uozumi, N.; Gambale, F.; Carpaneto, A
