Any health care reform must allow continuation of robust Medicaid Buy-In programs for working people with disabilities
National health care reform must meet the unique health care needs of people with disabilities. However, obtaining health care coverage for a person with disabilities can be challenging in an employer-based health insurance environment. The final healthcare reform act must ensure that working people with disabilities retain the options they currently have to participate; any legislation should embed Medicaid Buy-in cocerage and provide states the flexibility they need to support individuals with disabilities in employmen
Fully automated planning for anatomical fetal brain MRI on 0.55T
Purpose: Widening the availability of fetal MRI with fully automatic
real-time planning of radiological brain planes on 0.55T MRI. Methods: Deep
learning-based detection of key brain landmarks on a whole-uterus EPI scan
enables the subsequent fully automatic planning of the radiological single-shot
Turbo Spin Echo acquisitions. The landmark detection pipeline was trained on
over 120 datasets from varying field strength, echo times and resolutions and
quantitatively evaluated. The entire automatic planning solution was tested
prospectively in nine fetal subjects between 20 and 37 weeks. Comprehensive
evaluation of all steps, the distance between manual and automatic landmarks,
the planning quality and the resulting image quality was conducted. Results:
Prospective automatic planning was performed in real-time without latency in
all subjects. The landmark detection accuracy was 4.21+-2.56 mm for the fetal
eyes and 6.47+-3.23 for the cerebellum, planning quality was 2.44/3 (compared
to 2.56/3 for manual planning) and diagnostic image quality was 2.14 compared
to 2.07 for manual planning. Conclusions: Real-time automatic planning of all
three key fetal brain planes was successfully achieved and will pave the way
towards simplifying the acquisition of fetal MRI thereby widening the
availability of this modality in non-specialist centres.Comment: 17 pages, 8 figures, 1 table, MR
Hubble Space Telescope Ultraviolet Spectroscopy of Fourteen Low-Redshift Quasars
We present low-resolution ultraviolet spectra of 14 low redshift (z<0.8)
quasars observed with HST/STIS as part of a Snap project to understand the
relationship between quasar outflows and luminosity. By design, all
observations cover the CIV emission line. Nine of the quasars are from the
Hamburg-ESO catalog, three are from the Palomar-Green catalog, and one is from
the Parkes catalog. The sample contains a few interesting quasars including two
broad absorption line (BAL) quasars (HE0143-3535, HE0436-2614), one quasar with
a mini-BAL (HE1105-0746), and one quasar with associated narrow absorption
(HE0409-5004). These BAL quasars are among the brightest known (though not the
most luminous) since they lie at z<0.8. We compare the properties of these BAL
quasars to the z1.4 Large Bright Quasar samples. By
design, our objects sample luminosities in between these two surveys, and our
four absorbed objects are consistent with the v ~ L^0.62 relation derived by
Laor & Brandt (2002). Another quasar, HE0441-2826, contains extremely weak
emission lines and our spectrum is consistent with a simple power-law
continuum. The quasar is radio-loud, but has a steep spectral index and a
lobe-dominated morphology, which argues against it being a blazar. The unusual
spectrum of this quasar resembles the spectra of the quasars PG1407+265,
SDSSJ1136+0242, and PKS1004+13 for which several possible explanations have
been entertained.Comment: Uses aastex.cls, 21 pages in preprint mode, including 6 figures and 2

BRCA2 polymorphic stop codon K3326X and the risk of breast, prostate, and ovarian cancers
Background: The K3326X variant in BRCA2 (BRCA2*c.9976A>T; p.Lys3326*; rs11571833) has been found to be associated with small increased risks of breast cancer. However, it is not clear to what extent linkage disequilibrium with fully pathogenic mutations might account for this association. There is scant information about the effect of K3326X in other hormone-related cancers.
Methods: Using weighted logistic regression, we analyzed data from the large iCOGS study including 76 637 cancer case patients and 83 796 control patients to estimate odds ratios (ORw) and 95% confidence intervals (CIs) for K3326X variant carriers in relation to breast, ovarian, and prostate cancer risks, with weights defined as probability of not having a pathogenic BRCA2 variant. Using Cox proportional hazards modeling, we also examined the associations of K3326X with breast and ovarian cancer risks among 7183 BRCA1 variant carriers. All statistical tests were two-sided.
Results: The K3326X variant was associated with breast (ORw = 1.28, 95% CI = 1.17 to 1.40, P = 5.9x10- 6) and invasive ovarian cancer (ORw = 1.26, 95% CI = 1.10 to 1.43, P = 3.8x10-3). These associations were stronger for serous ovarian cancer and for estrogen receptor–negative breast cancer (ORw = 1.46, 95% CI = 1.2 to 1.70, P = 3.4x10-5 and ORw = 1.50, 95% CI = 1.28 to 1.76, P = 4.1x10-5, respectively). For BRCA1 mutation carriers, there was a statistically significant inverse association of the K3326X variant with risk of ovarian cancer (HR = 0.43, 95% CI = 0.22 to 0.84, P = .013) but no association with breast cancer. No association with prostate cancer was observed.
Conclusions: Our study provides evidence that the K3326X variant is associated with risk of developing breast and ovarian cancers independent of other pathogenic variants in BRCA2. Further studies are needed to determine the biological mechanism of action responsible for these associations
The SDSS-V Black Hole Mapper Reverberation Mapping Project: Unusual Broad-Line Variability in a Luminous Quasar
We present a high-cadence multi-epoch analysis of dramatic variability of
three broad emission lines (MgII, H, and H) in the spectra of
the luminous quasar ((5100\r{A}) =
erg s) SDSS J141041.25+531849.0 at with 127 spectroscopic
epochs over 9 years of monitoring (2013-2022). We observe anti-correlations
between the broad emission-line widths and flux in all three emission lines,
indicating that all three broad emission lines "breathe" in response to
stochastic continuum variations. We also observe dramatic radial velocity
shifts in all three broad emission lines, ranging from 400 km
s to 800 km s, that vary over the course of the monitoring
period. Our preferred explanation for the broad-line variability is complex
kinematics in the broad-line region gas. We suggest a model for the broad-line
variability that includes a combination of gas inflow with a radial gradient,
an azimuthal asymmetry (e.g., a hot spot), superimposed on the stochastic
flux-driven changes to the optimal emission region ("line breathing"). Similar
instances of line-profile variability due to complex gas kinematics around
quasars are likely to represent an important source of false positives in
radial velocity searches for binary black holes, which typically lack the kind
of high-cadence data we analyze here. The long-duration, wide-field, and
many-epoch spectroscopic monitoring of SDSS-V BHM-RM provides an excellent
opportunity for identifying and characterizing broad emission-line variability,
and the inferred nature of the inner gas environment, of luminous quasars

Social cohesion and the notion of 'suspect communities': A study of the experiences and impacts of being 'suspect' for Irish communities and Muslim communities in Britain
In this article, we consider how the practice of conceiving of groups within civil society as 'communities' meshes with conceptualisations of certain populations as 'suspect' and consider some of the impacts and consequences of this for particular populations and for social cohesion. We examine how Irish and Muslim people in Britain have become aware of and have experienced themselves to be members of 'suspect communities' in relation to political violence and counterterrorism policies from 1974 to 2007 and investigate the impacts of these experiences on their everyday lives. The study focuses on two eras of political violence. The first coincides with the Irish Republican Army's (IRA) bombing campaigns in England between 1973 and 1996, when the perpetrators were perceived as 'Irish terrorists'; and the second since 2001, when, in Britain and elsewhere, the main threat of political violence has been portrayed as stemming from people who are assumed to be motivated by extreme interpretations of Islam and are often labelled as 'Islamic terrorists'. We outline why the concept of 'suspect communities' continues to be analytically useful for examining: the impact of 'bounded communities' on community cohesion policies; the development of traumatogenic environments and their ramifications; and for examining how lessons might be learnt from one era of political violence to another, especially as regards the negative impacts of practices of suspectification on Irish communities and Muslim communities. The research methods included discussion groups involving Irish and Muslim people. These demonstrated that with the removal of discourses of suspicion the common ground of Britain's urban multiculture was a sufficient basis for sympathetic exchanges. © 2012 Taylor and Francis Group, LLC
Differential Disclosure Across Social Network Ties Among Women Living with HIV
Women’s disclosure of their HIV serostatus across social network ties was examined in a sample of women living in Los Angeles (n = 234), using multivariate random intercept logistic regressions. Women with disclosure-averse attitudes were less likely to disclose, while women with higher CD4+ counts were significantly more likely to disclose, regardless of relationship type. Relative to all other types of relationships, spouses/romantic partners were greater than four times more likely to be the targets of disclosure. Women were more than 2.5 times more likely to disclose to a given network member if that target provided the woman with social support. Social network members whom women believed to be HIV-positive were more than 10 times more likely to be the targets of disclosure. The implications for how social roles and social identities are manifest in these results are discussed, including the implications such an interpretation has for future prevention research

SCIPP: An Expanded Community of Practice - Community Publishing
SCIPP redefines and expands the existing notions about what makes for a vibrant and robust community of practice by partnering CSUSB students and professors with K-12 students, parents, and educators, along with committed community partners. SCIPP encourages curiosity in ways that leads to critical thinking, exploration, risk taking , confidence building, open-mindedness, and other personal traits that equip them with the softskills to be active, critical, and creative contributors to our communities. SCIPP pedagogy embraces our students\u27 collective wisdom and focuses on relational building where multi-directional communication is promoted and students are viewed as equal stakeholders in their own educations. SCIPP puts collaboration into action which in turn fosters community-based lifelong learning. SCIPP provides the open intellectual space for future university students (our K-12 students) to engage with existing university students in meaningful ways so as to sustain interconnected partnerships facilitating community engagement. It supports parents as experts in the education of their children and acknowledges parents as the first conduits to spark their children’s imagination while they actively participate in education enriching activities and programs. Everyone involved is committed to creating a secure and open atmosphere for dreaming, sharing, and learning. Together we explore the aspects of community publishing through collaborative learning in formal and informal settings relating to digital and printed medias
