Alpha induced reaction cross section measurements on 162Er for the astrophysical Îł process
Funding Details: NSF, National Science Foundation. ©2014 Elsevier B.V. This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/3.0/). Funded by SCOAP3The cross sections of the Er162(α,γ)Yb166 and Er162(α,n)Yb165 reactions have been measured for the first time. The radiative alpha capture reaction cross section was measured from Ec.m.=16.09MeV down to Ec.m.=11.21MeV, close to the astrophysically relevant region (which lies between 7.8 and 11.48 MeV at 3 GK stellar temperature). The Er162(α,n)Yb165 reaction was studied above the reaction threshold between Ec.m.=12.19 and 16.09MeV. The fact that the Er162(α,γ)Yb166 cross sections were measured below the (α,n) threshold at first time in this mass region opens the opportunity to study directly the α-widths required for the determination of astrophysical reaction rates. The data clearly show that compound nucleus formation in this reaction proceeds differently than previously predicted. © 2014 Elsevier B.V.Peer reviewedFinal Published versio
Photon-induced Nucleosynthesis: Current Problems and Experimental Approaches
Photon-induced reactions play a key role in the nucleosynthesis of rare
neutron-deficient p-nuclei. The paper focuses on (gamma,alpha), (gamma,p), and
(gamma,n) reactions which define the corresponding p-process path. The relation
between stellar reaction rates and laboratory cross sections is analyzed for
photon-induced reactions and their inverse capture reactions to evaluate
various experimental approaches. An improved version S_C(E) of the
astrophysical S-factor is suggested which is based on the Coulomb wave
functions. S_C(E) avoids the apparent energy dependence which is otherwise
obtained for capture reactions on heavy nuclei. It is found that a special type
of synchrotron radiation available at SPring-8 that mimics stellar blackbody
radiation at billions of Kelvin is a promising tool for future experiments. By
using the blackbody synchrotron radiation, sufficient event rates for
(gamma,alpha) and (gamma,p) reactions in the p-process path can be expected.
These experiments will provide data to improve the nuclear parameters involved
in the statistical model and thus reduce the uncertainties of nucleosynthesis
calculations.Comment: 13 pages, 6 figures, EPJA, accepte

Dermoscopy: Expanding âScopeâ of Practice and Preventing Skin Cancer Deaths
Community health outreach workers (CHOWs) have been demonstrated to increase CRC screening patient education for vulnerable, medically underserved patients as well as increase CRC screening rates in rural populations.1,2 This project examined the effectiveness of CHOWs in increasing CRC screening rates among low-income, underserved ethnic minorities in Portland, Maine. Eligible patients were ages 50-75; due for CRC screening; enrolled in Medicaid or had no health insurance; and spoke Arabic, English, French, Kinyarwanda, Somali, Spanish or Vietnamese. Seven CHOWs were trained in CRC screening outreach and assigned to patients from their own ethnic communities where they employed culturally sensitive interventions to reduce barriers to CRC screening. CHOWs attempted contact with patients by phone four times prior to sending a language-specific letter to patients recommending CRC screening. CHOWs offered fecal immunochemical testing (FIT) or colonoscopy and provided tailored education and frequent reminders for colonoscopies, explanations about procedures for bowel preps, transportation to colonoscopies, reminders and instructions for FIT completion as well as assistance with health insurance and financial barriers. Upon completion of this session, participants should be able to: Define the role of a community health outreach worker (CHOW) in CRC screening. State three common sociocultural barriers patients experience for CRC screening. Identify the efficacy of CHOWs in increasing CRC screening rates
Dermoscopy: Expanding âScopeâ of Practice and Preventing Skin Cancer Deaths
In this hands-on preconference workshop, we will introduce dermoscopy, a proven adjunctive tool that increases sensitivity and specificity of melanoma detection and improves diagnostic accuracy for basal and squamous cell carcinomas. Participants will learn how to use a dermatoscope in clinical practice and learn the two-step algorithm to diagnose unknown skin lesions and determine the need for biopsy. Biopsy techniques will be taught with a handson evidence-based approach that can be applied at oneâs home institution. Participants will leave with fundamental competence in the use of dermoscopy for early skin cancer detection, improved understanding of biopsy techniques, tools to train others, free apps, Dermoscopedia, online resources, and online and in-person courses
