Transitioning together: A narrative analysis of the support accessed by partners of trans people

Historically trans people have often wrongly been advised that the gender role transition process will result in the breakdown of their relationships (Lev, 2004), and couples have often been provided with little support through this process. This paper presents an in-depth narrative analysis of the accounts of six cisgender women who have been partnered with trans individuals. It focuses on the support \ud
that non-trans partners accessed while their partner progressed through their gender transition. Support was deemed important by all participants in relation to their aim of remaining together with their partners. In terms of whom they accessed support from, participants spoke about interactions with other people in similar situations, with professional therapists, with the Gender Identity Clinics \ud
(GICs), and with their partners. In regards to therapy, some \ud
reported that their partner’s transition was a topic they did not need to discuss. Many reported they had to take an “educator” role in therapy, suggesting that more training for therapists is required. Those who attended GICs with their partner were ambivalent about whether they would have utilised support there if it had been available there, stating that locally situated support was preferable. The paper draws out the clinical implications in relation to these areas
Evaluation of extra-virgin olive oils shelf life using an electronic tongue: chemometric approach

Physicochemical quality parameters, olfactory and gustatory–retronasal positive sensations of extra-virgin olive oils vary during storage leading to a decrease in the overall quality. Olive oil quality decline may prevent the compliance of olive oil quality with labeling and significantly reduce shelf life, resulting in important economic losses and negatively condition the consumer confidence. The feasibility of applying an electronic tongue to assess olive oils’ usual commercial light storage conditions and storage time was evaluated and compared with the discrimination potential of physicochemical or positive olfactory/gustatory sensorial parameters. Linear discriminant models, based on subsets of 5–8 electronic tongue sensor signals, selected by the meta-heuristic simulated annealing variable selection algorithm, allowed the correct classification of olive oils according to the light exposition conditions and/or storage time (sensitivities and specificities for leave-one-out cross-validation: 82–96 %). The predictive performance of the E-tongue approach was further evaluated using an external independent dataset selected using the Kennard–Stone algorithm and, in general, better classification rates (sensitivities and specificities for external dataset: 67–100 %) were obtained compared to those achieved using physicochemical or sensorial data. So, the work carried out is a proof-of-principle that the proposed electrochemical device could be a practical and versatile tool for, in a single and fast electrochemical assay, successfully discriminate olive oils with different storage times and/or exposed to different light conditions.The authors acknowledge the financial support

Complementary person-supervisor fit: an investigation of Supplies-Values (S-V) fit, Leader-Member Exchange (LMX) and work outcomes

By applying the supplies-values (S-V) fit approach from the complementary person-environment (P-E) fit literature to the leader-employee perspective, and drawing upon social exchange theory, we examine how fulfillment of different work values is related to Leader-Member Exchange (LMX) and work outcomes. First, polynomial regression analyses combined with response surface analysis of data collected at two time points (N = 316) showed that LMX (Time 2) was higher the more the leader fulfills the employee’s work values (Time 1). Second, LMX (Time 2) was higher when leader supplies (Time 1) and employee work values (Time 1) were both high than when both were low. Third, analyses of data from a sub-sample of employees and their leaders (N = 140), showed that LMX (Time 2) played a mediating role on the relation between S-V fit (Time 1) and work outcomes (Time 2). Specifically, we found eight out of 10 relationships between S-V fit (Time 1) and leader-rated task performance and OCB (Time 2) to be fully mediated by LMX (Time 2). LMX (Time 2) partially mediated the relation between S-V fit (Time 1) and job satisfaction (Time 2) as only two out of five relationships were fully mediated
An algorithm to describe the solution set of any tropical linear system A x=B x

An algorithm to give an explicit description of all the solutions to any tropical linear system A x=B x is presented. The given system is converted into a finite (rather small) number p of pairs (S,T) of classical linear systems: a system S of equations and a system T of inequalities. The notion, introduced here, that makes p small, is called compatibility. The particular feature of both S and T is that each item (equation or inequality) is bivariate, i.e., it involves exactly two variables; one variable with coefficient 1 and the other one with -1. S is solved by Gaussian elimination. We explain how to solve T by a method similar to Gaussian elimination. To achieve this, we introduce the notion of sub-special matrix. The procedure applied to T is, therefore, called sub-specialization
Sequential multi-photon strategy for semiconductor-based terahertz
  detectors

A semiconductor-based terahertz-detector strategy, exploiting a
bound-to-bound-to-continuum architecture, is presented and investigated. In
particular, a ladder of equidistant energy levels is employed, whose step is
tuned to the desired detection frequency and allows for sequential multi-photon
absorption. Our theoretical analysis demonstrates that the proposed
multi-subband scheme could represent a promising alternative to conventional
quantum-well infrared photodetectors in the terahertz spectral region.Comment: Submitted to Journal of Applied Physic
A spectral line survey of Orion KL in the bands 486-492 and 541-577 GHz
  with the Odin satellite I. The observational data

Spectral line surveys are useful since they allow identification of new
molecules and new lines in uniformly calibrated data sets. Nonetheless, large
portions of the sub-millimetre spectral regime remain unexplored due to severe
absorptions by H2O and O2 in the terrestrial atmosphere. The purpose of the
measurements presented here is to cover wavelength regions at and around 0.55
mm -- regions largely unobservable from the ground. Using the Odin
astronomy/aeronomy satellite, we performed the first spectral survey of the
Orion KL molecular cloud core in the bands 486--492 and 541--576 GHz with
rather uniform sensitivity (22--25 mK baseline noise). Odin's 1.1 m size
telescope, equipped with four cryo-cooled tuneable mixers connected to broad
band spectrometers, was used in a satellite position-switching mode. Two mixers
simultaneously observed different 1.1 GHz bands using frequency steps of 0.5
GHz (25 hours each). An on-source integration time of 20 hours was achieved for
most bands. The entire campaign consumed ~1100 orbits, each containing one hour
of serviceable astro-observation. We identified 280 spectral lines from 38
known interstellar molecules (including isotopologues) having intensities in
the range 80 to 0.05 K. An additional 64 weak lines remain unidentified. Apart
from the ground state rotational 1(1,0)--1(0,1) transitions of ortho-H2O, H218O
and H217O, the high energy 6(2,4)--7(1,7) line of para-H2O and the
HDO(2,0,2--1,1,1) line have been observed, as well as the 1,0--0,1 lines from
NH3 and its rare isotopologue 15NH3. We suggest assignments for some
unidentified features, notably the new interstellar molecules ND and SH-.
Severe blends have been detected in the line wings of the H218O, H217O and 13CO
lines changing the true linewidths of the outflow emission.Comment: 21 pages, 10 figures, 7 tables, accepeted for publication in

Automatic Detection of Limb Prominences in 304 A EUV Images

A new algorithm for automatic detection of prominences on the solar limb in
304 A EUV images is presented, and results of its application to SOHO/EIT data
discussed. The detection is based on the method of moments combined with a
classifier analysis aimed at discriminating between limb prominences, active
regions, and the quiet corona. This classifier analysis is based on a Support
Vector Machine (SVM). Using a set of 12 moments of the radial intensity
profiles, the algorithm performs well in discriminating between the above three
categories of limb structures, with a misclassification rate of 7%. Pixels
detected as belonging to a prominence are then used as starting point to
reconstruct the whole prominence by morphological image processing techniques.
It is planned that a catalogue of limb prominences identified in SOHO and
STEREO data using this method will be made publicly available to the scientific
community.Comment: 13 pages, 6 figures (4 coloured
On Low Rank Matrix Approximations with Applications to Synthesis Problem
  in Compressed Sensing

We consider the synthesis problem of Compressed Sensing - given s and an MXn
matrix A, extract from it an mXn submatrix A', certified to be s-good, with m
as small as possible. Starting from the verifiable sufficient conditions of
s-goodness, we express the synthesis problem as the problem of approximating a
given matrix by a matrix of specified low rank in the uniform norm. We propose
randomized algorithms for efficient construction of rank k approximation of
matrices of size mXn achieving accuracy bounds O(1)sqrt({ln(mn)/k) which hold
in expectation or with high probability. We also supply derandomized versions
of the approximation algorithms which does not require random sampling of
matrices and attains the same accuracy bounds. We further demonstrate that our
algorithms are optimal up to the logarithmic in m and n factor. We provide
preliminary numerical results on the performance of our algorithms for the
synthesis problem
The Herschel Virgo Cluster Survey: IV. Resolved dust analysis of spiral
  galaxies

We present a resolved dust analysis of three of the largest angular size
spiral galaxies, NGC 4501 and NGC 4567/8, in the Herschel Virgo Cluster Survey
(HeViCS) Science Demonstration field. Herschel has unprecedented spatial
resolution at far-infrared wavelengths and with the PACS and SPIRE instruments
samples both sides of the peak in the far infrared spectral energy distribution
(SED).We present maps of dust temperature, dust mass, and gas-to-dust ratio,
produced by fitting modified black bodies to the SED for each pixel. We find
that the distribution of dust temperature in both systems is in the range ~19 -
22 K and peaks away from the centres of the galaxies. The distribution of dust
mass in both systems is symmetrical and exhibits a single peak coincident with
the galaxy centres. This Letter provides a first insight into the future
analysis possible with a large sample of resolved galaxies to be observed by
Herschel.Comment: Letter accepted for publication in A&A (Herschel special issue
Kinetic mixing of U(1)s for local string models

We study kinetic mixing between massless U(1)s in toroidal orbifolds with
D3-branes at orbifold singularities. We focus in particular on C^3/Z_4
singularities but also study C^3/Z_6 and C^3/Z'_6 singularities. We find
kinetic mixing can be present and describe the conditions for it to occur.
Kinetic mixing comes from winding modes in the N=2 sector of the orbifold. If
kinetic mixing is present its size depends only on the complex structure
modulus of the torus and is independent of the K\"ahler moduli. We also study
gauge threshold corrections for local Z_M x Z_N orbifold models finding that,
consistent with previous studies, gauge couplings run from the bulk winding
scale rather than the string scale.Comment: 37 pages, 10 figures; v2: references added, minor typos correcte
Steady dynamos in finite domains: an integral equation approach

The paper deals with the integral equation approach to steady kinematic
dynamo models in finite domains based on Biot-Savart's law. The role of the
electric potential at the boundary is worked out explicitly. As an example, a
modified version of the simple spherical $\alpha$-effect dynamo model proposed
by Krause and Steenbeck is considered in which the $\alpha$-coefficient is no
longer constant but may vary with the radial coordinate. In particular, the
results for the original model are re-derived. Possible applications of this
integral equation approach for numerical simulations of dynamos in arbitrary
geometry and for an ''inverse dynamo theory'' are sketched.Comment: 18 pages, submitted to Astron. Nach
A pure-carbon ring transistor: The role of topology and structure

We report results on the rectification properties of a carbon nanotube (CNT)
ring transistor, contacted by CNT leads, whose novel features have been
recently communicated by Watanabe et al. [Appl. Phys. Lett. 78, 2928 (2001)].
This paper contains results which are validated by the experimental
observations. Moreover, we report on additional features of the transmission of
this ring device which are associated with the possibility of breaking the lead
inversion symmetry. The linear conductance displays a "chessboard"-like
behavior alternated with anomalous zero-lines which should be directly
observable in experiments. We are also able to discriminate in our results
structural properties (quasi-onedimensional confinement) from pure topological
effects (ring configuration), thus helping to gain physical intuition on the
rich ring phenomenology.Comment: 3 pages, 4 figure
Magnetic phase diagram of the semi-Heusler alloys from first-principles

The magnetic phase diagram of the Mn-based semi-Heusler alloys is determined
at T=0 using first-principles calculations in conjunction with the
frozen-magnon approximation. We show that the magnetism in these systems
strongly depends on the number of conduction electrons, their spin polarization
and the position of the unoccupied Mn 3d states with respect to Fermi energy.
Various magnetic phases are obtained depending on these characteristics. The
conditions leading to diverse magnetic behavior are identified. We find that in
the case of a large conduction electron spin polarization and the unoccupied Mn
3d states lying far above the Fermi level, an RKKY-like ferromagnetic
interaction is dominating. On the other hand, the antiferromagnetic
superexchange becomes important in the presence of large peaks of the
unoccupied Mn 3d states lying close to the Fermi energy. The overall magnetic
behavior depends on the competition of these two exchange mechanisms. The
obtained results are in very good agreement with the available experimental
data.Comment: 4 pages, 3 figure
On the Energy-Momentum Tensor of the Scalar Field in Scalar--Tensor
  Theories of Gravity

We study the dynamical description of gravity, the appropriate definition of
the scalar field energy-momentum tensor, and the interrelation between them in
scalar-tensor theories of gravity. We show that the quantity which one would
naively identify as the energy-momentum tensor of the scalar field is not
appropriate because it is spoiled by a part of the dynamical description of
gravity. A new connection can be defined in terms of which the full dynamical
description of gravity is explicit, and the correct scalar field
energy-momentum tensor can be immediately identified. Certain inequalities must
be imposed on the two free functions (the coupling function and the potential)
that define a particular scalar-tensor theory, to ensure that the scalar field
energy density never becomes negative. The correct dynamical description leads
naturally to the Einstein frame formulation of scalar-tensor gravity which is
also studied in detail.Comment: Submitted to Phys. Rev D15, 10 pages. Uses ReVTeX macro
The Two Dimensional Projected Spatial Distribution of Globular Clusters:
  Method and Application to NGC4261

We present a new method for the determination of the two-dimensional (2D)
projected spatial distribution of globular clusters (GCs) in external galaxies.
This method is based on the K-Nearest Neighbor density estimator of Dressler
(1980), complemented by MonteCarlo simulations to establish the statistical
significance of the results. We apply this method to NGC4261, a "test galaxy"
where significant 2D anisotropy in the GC distribution has been reported. We
confirm that the 2D distribution of GC is not azimuthally isotropic. Moreover,
we demonstrate that the 2D distribution departures from the average GC radial
distribution results in highly significant spiral-like or broken shell
features. Overall, the same perturbations are found in "red" and "blue" GCs,
but with some differences. In particular, we observe a central feature, roughly
aligned with the minor axis of NGC4261, composed of red and most luminous GCs.
Blue and fainter GCs are more frequent at large radial distances and follow the
spiral-like features of the overall density structure. These results suggest a
complex merging history for NGC4261.Comment: 14 pages, 15 figures, accepted for publication in Ap
Heat Kernels on the AdS(2) cone and Logarithmic Corrections to Extremal
  Black Hole Entropy

We develop new techniques to efficiently evaluate heat kernel coefficients
for the Laplacian in the short-time expansion on spheres and hyperboloids with
conical singularities. We then apply these techniques to explicitly compute the
logarithmic contribution to black hole entropy from an N=4 vector multiplet
about a Z(N) orbifold of the near-horizon geometry of quarter--BPS black holes
in N=4 supergravity. We find that this vanishes, matching perfectly with the
prediction from the microstate counting. We also discuss possible
generalisations of our heat kernel results to higher-spin fields over Z(N)
orbifolds of higher-dimensional spheres and hyperboloids.Comment: 41 page
NGC1266 as a Local Candidate for Rapid Cessation of Star Formation

We present new Spectrographic Areal Unit for Research on Optical Nebulae
(SAURON) integral-field spectroscopy and Swift Ultraviolet Optical Telescope
(UVOT) observations of molecular outflow host galaxy NGC 1266 that indicate NGC
1266 has experienced a rapid cessation of star formation. Both the SAURON maps
of stellar population age and the Swift UVOT observations demonstrate the
presence of young ($< 1$ Gyr) stellar populations within the central 1 kpc,
while existing Combined Array for Research in Millimeter-wave Astronomy (CARMA)
CO(1--0) maps indicate that the sites of current star formation are constrained
to the inner few hundred parsecs of the galaxy only. The optical spectrum of
NGC 1266 from Moustakas & Kennicutt (2006) reveal a characteristic
post-starburst (K+A) stellar population and Davis et al. (2012) confirm that
ionized gas emission in the system originate from a shock. Galaxies with K+A
spectra and shock-like ionized gas line ratios may comprise an important,
overlooked segment of the post-starburst population, containing exactly those
objects in which the AGN is actively expelling the star-forming material. While
AGN activity is not the likely driver of the post-starburst event that occurred
500 Myr ago, the faint spiral structure seen in the Hubble Space Telescope
(HST) Wide-field Camera 3 (WFC3) Y-, J- and H-band imaging seems to point to
the possibility of gravitational torques being the culprit. If the molecular
gas were driven into the center at the same time as the larger scale galaxy
disk underwent quenching, the AGN might be able to sustain the presence of
molecular gas for $\gtrsim 1$ Gyr by cyclically injecting turbulent kinetic
energy into the dense molecular gas via a radio jet, inhibiting star formation.Comment: 11 pages, 7 figures, accepted by the Astrophysical Journa
Attractors, black objects, and holographic RG flows in 5d maximal gauged
  supergravities

We perform a systematic search for static solutions in different sectors of
5d $N=8$ supergravities with compact and non-compact gauged R-symmetry groups,
finding new and listing already known backgrounds. Due to the variety of
possible gauge groups and resulting scalar potentials, the maximally symmetric
vacua we encounter in these theories can be Minkowski, de Sitter, or anti-de
Sitter. There exist BPS and non-BPS near-horizon geometries and full solutions
with all these three types of asymptotics, corresponding to black holes,
branes, strings, rings, and other black objects with more exotic horizon
topologies, supported by $U(1)$ and $SU(2)$ charges. The asymptotically AdS$_5$
solutions also have a clear holographic interpretation as RG flows of field
theories on D3 branes, wrapped on compact 2- and 3-manifolds.Comment: 38 pages, 3 figures, 7 table
Measurements of Stellar Inclinations for Kepler Planet Candidates II:
  Candidate Spin-Orbit Misalignments in Single and Multiple-Transiting Systems

We present a test for spin-orbit alignment for the host stars of 25 candidate
planetary systems detected by the {\it Kepler} spacecraft. The inclination
angle of each star's rotation axis was estimated from its rotation period,
rotational line broadening, and radius. The rotation periods were determined
using the {\it Kepler} photometric time series. The rotational line broadening
was determined from high-resolution optical spectra with Subaru/HDS. Those same
spectra were used to determine the star's photospheric parameters (effective
temperature, surface gravity, metallicity) which were then interpreted with
stellar-evolutionary models to determine stellar radii. We combine the new
sample with the 7 stars from our previous work on this subject, finding that
the stars show a statistical tendency to have inclinations near 90$^\circ$, in
alignment with the planetary orbits. Possible spin-orbit misalignments are seen
in several systems, including three multiple-planet systems (KOI-304, 988,
2261). Ideally these systems should be scrutinized with complementary
techniques---such as the Rossiter-McLaughlin effect, starspot-crossing
anomalies or asteroseismology---but the measurements will be difficult owing to
the relatively faint apparent magnitudes and small transit signals in these
systems.Comment: 11 pages, 9 figures, accepted for publication in Ap
The cometary HII regions of DR 21: Bow shocks or champagne flows or
  both?

We present deep Very Large Array H66$\alpha$ radio recombination line (RRL)
observations of the two cometary HII regions in DR 21. With these sensitive
data, we test the "hybrid" bow shock/champagne flow model previously proposed
for the DR 21 HII regions. The ionized gas down the tail of the southern HII
region is redshifted by up to ~30 km/s with respect to the ambient molecular
gas, as expected in the hybrid scenario. The RRL velocity structure, however,
reveals the presence of two velocity components in both the northern and
southern HII regions. This suggests that the ionized gas is flowing along
cone-like shells, swept-up by stellar winds. The observed velocity structure of
the well-resolved southern HII region is most consistent with a picture that
combines a stellar wind with stellar motion (as in bow shock models) along a
density gradient (as in champagne flow models). The direction of the implied
density gradient is consistent with that suggested by maps of dust continuum
and molecular line emission in the DR 21 region.Comment: 22 pages, 9 figures, 2 tables, accepted for publication in A&
