On Axion's Effect on Propagation of Monochromatic Electromagnetic Wave Through Strong Magnetic Field
A possibility of detecting the effect of photon-axion mixing in a cavity
experiment is discussed. There are two photon-axion modes that acquire
different indices of refraction and split in an inhomogeneous magnetic field.
For a magnetic field inhomogeneous in the direction transverse to the light
propagation an analytical solution is obtained both for the index of refraction
and the beams' trajectories. In a cavity experiment, the beam splitting creates
a bifurcation effect, which results in a decrease of the light intensity in the
central region. Modulation of magnetic field can separate this effect from
background by providing a narrow frequency range for any observed signal. When
one integrates this effect over time and accounts for bandwidth, the overall
drop in FWHM intensity is of order 10-2%. This is a very measurable effect.Comment: 5 pages with 2 figure
Criminalizing Asylum: DNA Testing Asylum Seekers Violates Privacy Rights
Introduction.
On June 16, 2015, President Trump announced his 2016 presidential campaign and claimed that Mexicans are criminals who “[h]ave lots of problems . . . they’re bringing drugs. They’re bringing crime. They’re rapists . . . It’s coming from all over . . . Latin America.” President Trump has publicly expressed his hostility towards immigrants by calling them “animals” and blaming them for drugs and gangs in the United States. While in office, President Trump tweeted that immigrants were invading the United States and suggested that “we must immediately, with no Judges or Court Cases, bring them back from where they came.
Large Dog Relinquishment to Two Municipal Facilities in New York City and Washington, D.C.: Identifying Targets for Intervention
While the overall trend in euthanasia has been decreasing nationally, large dogs are at a higher risk of euthanasia than other sized dogs in most animal shelters in the United States. We hypothesized one way to increase the lives saved with respect to these large dogs is to keep them home when possible. In order to develop solutions to decrease relinquishment, a survey was developed to learn more about the reasons owners relinquish large dogs. The survey was administered to owners relinquishing their dogs at two large municipal facilities, one in New York City and one in Washington, D.C. There were 157 responses between the two facilities. We found both significant similarities and differences between respondents and their dogs from the two cities. We identified opportunities to potentially support future relinquishers and found that targets for interventions are likely different in each community
Estrogenic activity, race/ethnicity, and Indigenous American ancestry among San Francisco Bay Area women.
Estrogens play a significant role in breast cancer development and are not only produced endogenously, but are also mimicked by estrogen-like compounds from environmental exposures. We evaluated associations between estrogenic (E) activity, demographic factors and breast cancer risk factors in Non-Latina Black (NLB), Non-Latina White (NLW), and Latina women. We examined the association between E activity and Indigenous American (IA) ancestry in Latina women. Total E activity was measured with a bioassay in plasma samples of 503 women who served as controls in the San Francisco Bay Area Breast Cancer Study. In the univariate model that included all women with race/ethnicity as the independent predictor, Latinas had 13% lower E activity (p = 0.239) and NLBs had 35% higher activity (p = 0.04) compared to NLWs. In the multivariable model that adjusted for demographic factors, Latinas continued to show lower E activity levels (26%, p = 0.026), but the difference between NLBs and NLWs was no longer statistically significant (p = 0.431). An inverse association was observed between E activity and IA ancestry among Latina women (50% lower in 0% vs. 100% European ancestry, p = 0.027) consistent with our previously reported association between IA ancestry and breast cancer risk. These findings suggest that endogenous estrogens and exogenous estrogen-like compounds that act on the estrogen receptor and modulate E activity may partially explain racial/ethnic differences in breast cancer risk
Impact of breast cancer subtypes on 3-year survival among adolescent and young adult women.
IntroductionYoung women have poorer survival after breast cancer than do older women. It is unclear whether this survival difference relates to the unique distribution of hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2)-defined molecular breast cancer subtypes among adolescent and young adult (AYA) women aged 15 to 39 years. The purpose of our study was to examine associations between breast cancer subtypes and short-term survival in AYA women, as well as to determine whether the distinct molecular subtype distribution among AYA women explains the unfavorable overall breast cancer survival statistics reported for AYA women compared with older women.MethodsData for 5,331 AYA breast cancers diagnosed between 2005 and 2009 were obtained from the California Cancer Registry. Survival by subtype (triple-negative; HR+/HER2-; HR+/HER2+; HR-/HER2+) and age-group (AYA versus 40- to 64-year-olds) was analyzed with Cox proportional hazards regression with follow-up through 2010.ResultsWith up to 6 years of follow-up and a mean survival time of 3.1 years (SD = 1.5 years), AYA women diagnosed with HR-/HER + and triple-negative breast cancer experienced a 1.6-fold and 2.7-fold increased risk of death, respectively, from all causes (HR-/HER + hazard ratio: 1.55; 95% confidence interval (CI): 1.10 to 2.18; triple-negative HR: 2.75; 95% CI, 2.06 to 3.66) and breast cancer (HR-/HER + hazard ratio: 1.63; 95% CI, 1.12 to 2.36; triple-negative hazard ratio: 2.71; 95% CI, 1.98 to 3.71) than AYA women with HR+/HER2- breast cancer. AYA women who resided in lower socioeconomic status neighborhoods, had public health insurance, and were of Black, compared with White, race/ethnicity experienced worse survival. This race/ethnicity association was attenuated somewhat after adjusting for breast cancer subtypes (hazard ratio, 1.33; 95% CI, 0.98 to 1.82). AYA women had similar all-cause and breast cancer-specific short-term survival as older women for all breast cancer subtypes and across all stages of disease.ConclusionsAmong AYA women with breast cancer, short-term survival varied by breast cancer subtypes, with the distribution of breast cancer subtypes explaining some of the poorer survival observed among Black, compared with White, AYA women. Future studies should consider whether distribution of breast cancer subtypes and other factors, including differential receipt of treatment regimens, influences long-term survival in young compared with older women
Situational Awareness/Triage Tool For Use In a Chemical, Biological, Radiological Nuclear Explosive (CBRNE) Environment
A method of managing patient care and emergency response following a Chemical, Biological, Radiological, or Nuclear Explosive (CBRNE) attack and maintaining compliance with the Health Insurance Portability and Accountability Act (HIPAA). The method including identifying each patient with a unique patient identifier, the identifier based upon the geospatial location of the patient, the geospatial location including at least the latitude and longitude of the patient when first treated, the unique patient identifier being part of patient data. Providing a collection point of patient data to form a patient data database where in the patient location data may be used to map the location, and severity of patient injuries. The method may include using the patient database is used to assist determining the type of attack and/or assist directing the distribution of medical resources. The patient data may be updated as treatment is administered. The treatment may include medication, decontamination, vaccination or a combination thereof. The patient data may be maintained on a hardware data card with the patient. The hardware data card patient data may be integrated with HIPPA patient data at a medical facility
Black Models Matter: Challenging the Racism of Aesthetics and the Facade of Inclusion in the Fashion Industry
The global fashion market is expanding every day, but often, the global fashion runways do not reflect that reality. On average, black models make up for six percent of models used on the runway during the fashion month calendar. This small percentage is also mirrored in advertisements and editorials featured in popular fashion magazines. In the 1970s, black models were met with great opportunities, and that success trickled down into the 1980s and the 1990s. As the 90s came to a close, top designers opted for an aesthetic that ultimately excluded models of color, but black models beared the brunt of that deal. Since then, the conversation surrounding racism in fashion surfaces every season, as the numbers of black models remains stagnant. Is the fashion industry racist? Who is to blame? How can the issues be addressed so that black models can thrive as their white counterparts have? Will fashion ever exist in an era that mirrors the 1970s
Representativeness of breast cancer cases in an integrated health care delivery system.
BackgroundIntegrated health care delivery systems, with their comprehensive and integrated electronic medical records (EMR), are well-poised to conduct research that leverages the detailed clinical data within the EMRs. However, information regarding the representativeness of these clinical populations is limited, and thus the generalizability of research findings is uncertain.MethodsUsing data from the population-based California Cancer Registry, we compared age-adjusted distributions of patient and neighborhood characteristics for three groups of breast cancer patients: 1) those diagnosed within Kaiser Permanente Northern California (KPNC), 2) non-KPNC patients from NCI-designated cancer centers, and 3) those from all other hospitals.ResultsKPNC patients represented 32 % (N = 36,109); cancer center patients represented 7 % (N = 7805); and all other hospitals represented 61 % (N = 68,330) of the total breast cancer patients from this geographic area during 1996-2009. Compared with cases from all other hospitals, KPNC had slightly fewer non-Hispanic Whites (70.6 % versus 74.4 %) but more Blacks (8.1 % versus 5.0 %), slightly more patients in the 50-69 age range and fewer in the younger and older age groups, a slightly lower proportion of in situ but higher proportion of stage I disease (41.6 % versus 38.9 %), were slightly less likely to reside in the lowest (4.2 % versus 6.5 %) and highest (36.2 % versus 39.0 %) socioeconomic status neighborhoods, and more likely to live in suburban metropolitan areas and neighborhoods with more racial/ethnic minorities. Cancer center patients differed substantially from patients from KPNC and all other hospitals on all characteristics assessed. All differences were statistically significant (p < .001).ConclusionsAlthough much of clinical research discoveries are based in academic medical centers, patients from large, integrated medical centers are likely more representative of the underlying population, providing support for the generalizability of cancer research based on electronic data from these centers
Associations between breast cancer subtype and neighborhood socioeconomic and racial composition among Black and White women
PURPOSE: Studies of Black-White differences in breast cancer subtype often emphasize potential ancestry-associated genetic or lifestyle risk factors without fully considering how the social or economic implications of race in the U.S. may influence risk. We assess whether neighborhood racial composition and/or socioeconomic status are associated with odds of triple-negative breast cancer (TNBC) diagnosis relative to the less-aggressive hormone receptor-positive/HER2-negative subtype (HR+ /HER-), and whether the observed relationships vary across women\u27s race and age groups.
METHODS: We use multilevel generalized estimating equation models to evaluate odds of TNBC vs. HR+ /HER2- subtypes in a population-based cohort of 7291 Black and 74,208 White women diagnosed with breast cancer from 2006 to 2014. Final models include both neighborhood-level variables, adjusting for individual demographics and tumor characteristics.
RESULTS: Relative to the HR+ /HER- subtype, we found modestly lower odds of TNBC subtype among White women with higher neighborhood median household income (statistically significant within the 45-64 age group, OR = 0.981 per 10,000 increase; OR = 0.942 per 10% increase in Black residents).
CONCLUSION: The relationships between neighborhood composition, neighborhood socioeconomic status, and odds of TNBC differ by race and age. Racially patterned social factors warrant further exploration in breast cancer subtype disparities research
Target Personification Influences the Positive Emotional Link Between Generating and Implementing Malevolently Creative Ideas
Research on malevolent creativity has rarely linked the generation of harmful ideas with their implementation (i.e., malevolent innovation). To explain why people might act upon their malevolently creative ideas, we drew on affective events theory. Specifically, given evidence that aggressive and creative thought events can elicit positive emotions, we argued that generating new and harmful ideas can evoke positive emotional states that make malevolent innovation a more desirable course of action. We first tested our mediational pathway in two studies with different malevolent creativity tasks. Finding only partial support for our predictions in Study 1 (N = 126), but full support in Study 2 (N = 296), we reflected on our study tasks and suspected that our mixed results may have occurred because the target of ideas in Study 2 embodied more human qualities than in Study 1. Thus, we integrated theory on target personification to see if assigning personhood to a target moderated the malevolent creativity-innovation pathway. We tested our updated model in Study 3 (N = 214) and found that the indirect effect of malevolent creativity on the desire to implement ideas (through positive emotions) was indeed conditional upon individuals’ personification of a target. Plain Language Summary
Little research has examined why and when people might act upon their malevolently creative (i.e., new and harmful) ideas. Given evidence that aggression and creativity can both arouse positive emotional states, it may be possible that forming malevolently creative ideas can make people feel more positively about implementing them later on. However, our research findings paint a more nuanced picture, suggesting that the emotional link between generating and implementing malevolently creative ideas only occurs when people see their targets as more human-like (i.e., they can assign personhood to their targets)
