Theoretical aspects of the study of top quark properties
We review some recent theoretical progresses towards the determination of the
top-quark couplings beyond the standard model. We briefly introduce the global
effective field theory approach to the top-quark production and decay
processes, and discuss the most useful observables to constrain the deviations.
Recent improvements with a focus on QCD corrections and corresponding tools are
also discussed.Comment: 8 pages, 6 figures. Based on plenary talk given at LHCP2017,

Semiclassical trajectory-coherent states of the nonlocal Gross-Pitaesvkii equation with radial symmetry
In this paper the semiclassical formalism is applied to the nonlocal Gross-Pitaevskii equation with radial symmetry. Some aspects of constructing of semiclassically concentrated solutions in polar coordinates are shown. The semiclassical trajectory-coherent states, concentrated on the ring, are obtained. The example of specific physically motivated equation is considered and some properties of its semiclassical trajectorycoherent states are noted
Fleroxacin (Ro 23-6240): activity in virtro against 355 enteropathogenic and non-fermentative Gram-negative bacilli and Legionella pneumophila
The antibacterial activity of fleroxacin (Ro 23-6240, AM-833), a new 6-fluoroquinolone, was determined against 149 strains of enteropathogenic bacteria (17 species) and 191 strains (28 species) of glucose non-fermentative Gram-negative rods (excluding Pseudomonas aeruginosa), and against 15 strains of Legionella pneumophila. The cumulative susceptibility of these groups of bacteria to Ro 23-6240 at the 2 mg/l level were 99.2% 80.1 and 100% of tested strains, respectivel

THE FACTORS OF AN INDIANA BACKGROUND THAT INFLUENCE PRACTICE LOCATION CHOICE OF RESIDENCY AND FELLOWSHIP GRADUATES
poster abstractA shortage and unequal distribution of health care professionals in Indiana is increasingly restricting access to quality medical care for Indiana residents. There is a limited amount of research on the factors that predominate when residency and fellowship graduates choose their practice location. This pro-ject looks at the different factors affecting graduates’ choices of practice lo-cation, while specifically focusing on the connection of hometown, high school, college, and medical school locations to their decisions to practice in Indiana. Surveys were completed by 264 of the 383 graduating residents and fellows of the graduate medical education programs at Indiana Universi-ty School of Medicine during the exit interview process, yielding a response rate of 69%. The graduates responded to questions concerning demographic characteristics, assessment of their training, plans after graduation, intended practice location, and reasons for choosing their practice location. The larg-est contributor to choosing to practice in Indiana was graduating from a medical school in Indiana (80.6%). Having an Indiana hometown was the least contributing factor (76.1%), but the combination of hometown and medical school was the highest contributing factor (82.1%) to choosing to practice in Indiana. The top three reasons to stay in Indiana given by re-spondents who graduated from an Indiana medical school were “met my professional needs or preferences” (88.0%), “liked the people” (86.0%), and “met my personal needs or preferences” (76.0%). Also, factors concerning the needs of their spouse and family were only moderately important. This project’s data may assist admission committees when choosing graduates for their residency programs. By admitting more graduates who have deeper connections to Indiana, the number of health professionals in Indiana may increase, thus allowing more of Indiana’s residents to have access to quality health care
Adult BMI change and risk of Breast Cancer: National Health and Nutrition Examination Survey (NHANES) 2005-2010
OBJECTIVE: Breast cancer is the second leading cause of cancer mortality among women in the developed world. This study assessed the association between occurrence of breast cancer and body mass index (BMI) change from age 25 to age closest to breast cancer diagnosis while exploring the modifying effects of demographic variables.
METHODS: The National Health and Nutrition Examination Survey data were used. Women included were ≥50 years, not pregnant and without a diagnosis of any cancer but breast. The total sample included 2895 women (172 with breast cancer and 2723 controls with no breast cancer diagnosis). Multivariate logistic regression was used to estimate the OR and 95 % CIs and interaction evaluated by including an interaction term in the model.
RESULTS: Women whose BMI increased from normal or overweight to obese compared to those who remained at a normal BMI were found to have a 2 times higher odds (OR = 2.1; 95 % CI 1.11-3.79) of developing breast cancer. No significant association was observed for women who increased to overweight. However, a more pronounced association was observed in non-Hispanic black women (OR = 6.6; 95 % CI 1.68-25.86) and a significant association observed when they increased from normal to overweight (OR = 4.2; 95 % CI 1.02-17.75).
CONCLUSIONS: Becoming obese after age 25 is associated with increased risk of breast cancer in women over 50 years old, with non-Hispanic black women being at greatest risk
Issue Brief: Indiana’s Health Professions Workforce Shortages and Mal-distribution
Workforce shortages have been documented across a broad spectrum of health profession disciplines in Indiana. Currently, federal, state and local programs exist to recruit and retain health professionals in our state; however, these programs have had minimal impact on the underlying factors that contribute to the problem. Additional steps must be taken to expand the supply of health professionals to adequately meet the growing need for health care services among Indiana residents. While many health professional shortages exist, this brief will focus on the primary care physicians and nurses needed to provide medical homes for residents of our state
Molecular Design Parameters of Anthraquinone Dyes for Guest-Host Liquid-Crystal Applications : Experimental and Computational Studies of Spectroscopy, Structure and Stability
A set of five anthraquinone dyes with bis(4-propylphenyl) substituent groups, connected via sulfide or amine linkages at the 1,5-positions or directly at the 2,6-positions, have been studied in solution by UV-vis spectroscopy and electrochemistry, allied with density functional theory calculations of structures, electronic transitions, and redox potentials. The visible transitions and redox potentials are shown to vary with the HOMO and LUMO energies, with the variation in both color and redox stability between the dyes being attributable principally to variations in the HOMOs located mainly on the substituents and outer anthraquinone rings. The calculated molecular structures and visible transition dipole moments are shown to vary subtly with substituent, giving variations in the molecular aspect ratios, minimum moment of inertia axes, and transition dipole moment vector orientations that can rationalize the alignment trends reported in the literature for such anthraquinone dyes in liquid crystal hosts, showing why 1,5-disulfide and 2,6-diphenyl substituents give better designs than 1,5-diamine substituents. The computational approaches reported here are shown to give good matches with experimental trends, indicating that they may be used more generally to aid the rational molecular design of dyes for applications as guests in liquid crystal hosts
