Why don\u27t you hit me? (or men of color versus white women: anatomy of a dilemma)
Christopher Gallegos presents CSP readers with a very personal account on heterosexual attraction, and the levels of complexity that gender and ethnicity bring to this all too human experience. The piece is portrayed by the author as a man of color\u27s manifesto against the marketing of the white woman as the sole example of female beauty. It is unfair to everyone: men and women of color and the white women themselves
Holographic spin liquids and Lovelock Chern-Simons gravity
We explore the role of torsion as source of spin current in strongly
interacting conformal fluids using holography. We establish the constitutive
relations of the basic hydrodynamic variables, the energy-momentum tensor and
the spin current based on the classification of the spin sources in irreducible
Lorentz representations. The fluids we consider are assumed to be described by
the five dimensional Lovelock-Chern-Simons gravity with independent vielbein
and spin connection. We construct a hydrodynamic expansion that involves the
stress tensor and the spin current and compute the corresponding one-point
functions holographically. As a byproduct we find a class of interesting
analytic solutions to the Lovelock-Chern-Simons gravity, including blackholes,
by mapping the equations of motion into non-linear algebraic constraints for
the sources. We also derive a Lee-Wald entropy formula for these blackholes in
Chern-Simons theories with torsion. The blackhole solutions determine the
thermodynamic potentials and the hydrodynamic constitutive relations in the
corresponding fluid on the boundary. We observe novel spin induced transport in
these holographic models: a dynamical version of the Barnett effect where
vorticity generates a spin current and anomalous vortical transport transverse
to a vector-like spin source.Comment: 52 page
Torsional Newton Cartan gravity from non-relativistic strings
We study propagation of closed bosonic strings in torsional Newton-Cartan
geometry based on a recently proposed Polyakov type action derived by
dimensional reduction of the ordinary bosonic string along a null direction. We
generalize the Polyakov action proposal to include matter, i.e. the 2-form and
the 1-form that originates from the Kalb-Ramond field and the dilaton. We
determine the conditions for Weyl invariance which we express as the
beta-function equations on the worldsheet, in analogy with the usual case of
strings propagating on a pseudo-Riemannian manifold. The critical dimension of
the TNC space-time turns out to be 25. We find that Newton's law of gravitation
follows from the requirement of quantum Weyl invariance in the absence of
torsion. Presence of the 1-form requires torsion to be non vanishing. Torsion
has interesting consequences, in particular it yields a mass term and an
advection term in the generalized Newton's law. U(1) mass invariance of the
theory is an important ingredient in deriving the beta functions.Comment: Summary of results added. Reorganization and generalization of

Salvia palmetorum (Lamiaceae), una especie nueva de Sonora, México
A new Salvia L. species was discovered in the vicinity of San Carlos Bay (Guaymas county) in Sonora, Mexico. The discovery was carried out during botanical explorations for the floristic inventory of the area. The new taxon is described and illustrated. This is an interesting addition to the Flora of Sonora because it constitutes the first Salvia endemic to this state. The species is characterized by an unusual combination of characters within Salvia subg. Calosphace (Benth.) Epling: densely white-tomentulose stems, presence of bracteoles, flowers arranged in thyrses, trimucronate upper calyx lip and ornate connective with an antrorse obtuse tooth. The taxon is also atypical among Mexican Salvia subg. Calosphace in growing in palm groves below 100 m elevation.Open access articleThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Damage Characterization Method for Structural Health Management Using Reduced Number of Sensor Inputs
The development of validated multidisciplinary Integrated Vehicle Health Management (IVHM) tools, technologies, and techniques to enable detection, diagnosis, prognosis, and mitigation in the presence of adverse conditions during flight will provide effective solutions to deal with safety related challenges facing next generation aircraft. The adverse conditions include loss of control caused by environmental factors, actuator and sensor faults or failures, and damage conditions. A major concern in these structures is the growth of undetected damage (cracks) due to fatigue and low velocity foreign impacts that can reach a critical size during flight, resulting in loss of control of the aircraft. Hence, development of efficient methodologies to determine the presence, location, and severity of damage in critical structural components is highly important in developing efficient structural health management systems

A non-relativistic limit of M-theory and 11-dimensional membrane Newton-Cartan geometry
We consider a non-relativistic limit of the bosonic sector of
eleven-dimensional supergravity, leading to a theory based on a covariant
`membrane Newton-Cartan' (MNC) geometry. The local tangent space is split into
three `longitudinal' and eight `transverse' directions, related only by
Galilean rather than Lorentzian symmetries. This generalises the
ten-dimensional stringy Newton-Cartan (SNC) theory. In order to obtain a finite
limit, the field strength of the eleven-dimensional four-form is required to
obey a transverse self-duality constraint, ultimately due to the presence of
the Chern-Simons term in eleven dimensions. The finite action then gives a set
of equations that is invariant under longitudinal and transverse rotations,
Galilean boosts and local dilatations. We supplement these equations with an
extra Poisson equation, coming from the subleading action. Reduction along a
longitudinal direction gives the known SNC theory with the addition of RR gauge
fields, while reducing along a transverse direction yields a new
non-relativistic theory associated to D2 branes. We further show that the MNC
theory can be embedded in the U-duality symmetric formulation of exceptional
field theory, demonstrating that it shares the same exceptional Lie algebraic
symmetries as the relativistic supergravity, and providing an alternative
derivation of the extra Poisson equation.Comment: 52 pages + appendices, v2: matches published version, one word added
