Rational Connectivity and Analytic Contractibility
Let k be an algebraically closed field of characteristic 0, and let f be a
morphism of smooth projective varieties from X to Y over the ring k((t)) of
formal Laurent series. We prove that if a general geometric fiber of f is
rationally connected, then the Berkovich analytifications of X and Y are
homotopy equivalent. Two important consequences of this result are that the
homotopy type of the Berkovich analytification of any smooth projective variety
X over k((t)) is a birational invariant of X, and that the Berkovich
analytification of a rationally connected smooth projective variety over k((t))
is contractible
A Relation Between the Warm Neutral and Ionized Media Observed in the Canadian Galactic Plane Survey
We report on a comparison between 21 cm rotation measure (RM) and the
optically-thin atomic hydrogen column density (N_HI) measured towards
unresolved extragalactic sources in the Galactic plane of the northern sky. HI
column densities integrated to the Galactic edge are measured immediately
surrounding each of nearly 2000 sources in 1-arcminute 21 cm line data, and are
compared to RMs observed from polarized emission of each source. RM data are
binned in column-density bins 4x10^20 cm^-2 wide, and one observes a strong
relationship between the number of hydrogen atoms in a 1 cm^2 column through
the plane and the mean RM along the same line-of-sight and path length. The
relationship is linear over one order of magnitude (from 0.8-14x10^21 atoms
cm^-2) of column densities, with a constant RM/N_HI -23.2+/-2.3 rad m^-2/10^21
atoms cm^-2, and a positive RM of 45.0+/-13.8 rad m^-2 in the presence of no
atomic hydrogen. This slope is used to calculate a mean volume-averaged
magnetic field in the 2nd quadrant of ~1.0+/-0.1 micro-Gauss directed
away from the Sun, assuming an ionization fraction of 8% (consistent with the
WNM). The remarkable consistency between this field and =1.2 micro-Gauss
found with the same RM sources and a Galactic model of dispersion measures
suggests that electrons in the partially ionized WNM are mainly responsible for
pulsar dispersion measures, and thus the partially-ionized WNM is the dominant
form of the magneto-ionic interstellar medium.Comment: 6 pages, 4 figures, accepted for publication in the Astrophysical

Water-resource records of Brevard County, Florida
The U. S. Geological Survey made a comprehensive
investigation of the water resources of Brevard County
from 1954 to 1958. The purposes of this investigation were:
(1) to determine the occurrence and chemical quality of
water in the streams and lakes, (2) to determine the location
and the thickness of aquifers, and (3) to determine the
occurrence and chemical quality of the ground water. During
the period from 1933 to 1954, water records were collected
from a few stream-gaging stations and a few observation
wells. The purpose of this report is to present basic data
collected during these investigations. (Document has 188 pages.

Perceived abortion stigma and psychological well-being over five years after receiving or being denied an abortion.
OBJECTIVE:To prospectively assess perceptions of abortion stigma after receiving or being denied an abortion over 5 years, the factors associated with perceived abortion stigma, and the effects of perceived abortion stigma on psychological well-being. METHODS:We recruited people seeking abortion from 30 facilities across the US, and interviewed them by phone one week post-abortion seeking, then semiannually for 5 years. We used adjusted mixed effects regression analyses to examine the abortion stigma trajectories of those who obtained an abortion near a facility's gestational age limit (Near-limits) compared to those denied an abortion because they were just over the limit and carried their pregnancies to term (Turnaway-births). RESULTS:Of the 956 people recruited, we removed 28 due to ineligibility or missing data, leaving a final sample of 928. In unadjusted analyses, at one-week post-abortion seeking, over half of those seeking abortion perceived that if others knew they had sought an abortion, they would be looked down upon at least "a little bit" by people close to them (60%) or by people in their community (56%). In longitudinal adjusted analyses, people denied an abortion and who carried their pregnancies to term (Turnaway-birth group) reported significantly lower baseline perceived abortion stigma from people close to them (-0.38; 95% CI, -0.59, -0.16) and from people in their community (0.30; 95% CI, -0.52, -0.08), than Near-limits, differences that remained statistically significant for 1.5 years. Overall perceived abortion stigma declined significantly (p < .001) for both study groups. High perceived abortion stigma at baseline was associated with higher odds of experiencing psychological distress years later (adjusted Odds Ratio, 3.98; 95% CI, 1.39, 11.37). CONCLUSIONS:Most people considering abortion perceive some abortion stigma, which is associated with psychological distress years later
Variable mixer propulsion cycle
A design technique, method and apparatus are delineated for controlling the bypass gas stream pressure and varying the bypass ratio of a mixed flow gas turbine engine in order to achieve improved performance. The disclosed embodiments each include a mixing device for combining the core and bypass gas streams. The variable area mixing device permits the static pressures of the core and bypass streams to be balanced prior to mixing at widely varying bypass stream pressure levels. The mixed flow gas turbine engine therefore operates efficiently over a wide range of bypass ratios and the dynamic pressure of the bypass stream is maintained at a level which will keep the engine inlet airflow matched to an optimum design level throughout a wide range of engine thrust settings

Equivalence of Narcissistic Personality Inventory constructs and correlates across scoring approaches and response formats
The prevalent scoring practice for the Narcissistic Personality Inventory (NPI) ignores the forced-choice nature of the items. The aim of this study was to investigate whether findings based on NPI scores reported in previous research can be confirmed when the forced-choice nature of the NPI’s original response format is appropriately modeled, and when NPI items are presented in different response formats (true/false or rating scale). The relationships between NPI facets and various criteria were robust across scoring approaches (mean score vs. model-based), but were only partly robust across response formats. In addition, the scoring approaches and response formats achieved equivalent measurements of the vanity facet and in part of the leadership facet, but differed with respect to the entitlement facet
New horizons for the methodology and physiology of training periodization: Block Periodization: New horizon or a false dawn?
It would appear premature to herald block periodization as a ‘new horizon’ in training planning, partly because of a fundamental lack of supporting evidence and clearly delineated rationale, and partly because contradictory evidence exists questioning its universal efficacy in elite contexts. What block periodization does positively contribute to current planning methodologies is a more formal description of a particular planning tactic that may be advantageously added to the elite coaches menu of potential planning options. Therefore, while blocked-training schemes may be useful ploys in specific training contexts, the claim that this framework represents a new departure in training planning may be somewhat overly enthusiastic. Hence, perhaps a more appropriate description of block periodization is ‘new variation’, rather than a ‘new horizon’, in sports training planning
Soft SUSY Breaking Grand Unification: Leptons vs Quarks on the Flavor Playground
We systematically analyze the correlations between the various leptonic and
hadronic flavor violating processes arising in SUSY Grand Unified Theories.
Using the GUT-symmetric relations between the soft SUSY breaking parameters, we
assess the impact of hadronic and leptonic flavor observables on the SUSY
sources of flavor violation.Comment: 39 pages, 10 figure
