K\"ahlerian Effective Potentials for Chern-Simons-Matter Theories
In this paper, we will calculate the effective potential for a theory of
multiple M2-branes. As the theory of multiple M2-branes can be described by a
Chern-Simons-matter theory, this will be done by calculating the K\"ahlerian
effective potential for a Chern-Simons-matter theory. This calculation will be
performed in superspace formalism. We will initially study an
Abelian Chern-Simons-matter theory, and then generalize those results to the
full non-Abelian Chern-Simons-matter theory. We will obtain explicit
expressions for the superpropagators for this theory. These superpropagators
will be used to calculate the one-loop effective potential.Comment: 15 page
Current Clinical Applications of Testicular Cancer Biomarkers
Current use of testicular biomarkers for screening, diagnosis, and follow-up is reviewed in the context of potential clinical utility of these tests. This information will be of value to clinicians to determine patient suitability for certain treatments and will also assist in reviewing current literature regarding potential biomarkers that may be used for testicular cancer
Mixed-signal circuits and boards for high safety applications
A design methodology for analogue on-line test is presented by means of a real circuit implementation. The test strategy is based on monitoring via a very small analogue checker the inputs of all operational ampliers of a fully di erential circuit. The self-checking properties of the functional circuit are evaluated for a hard/soft fault model. Since the analogue checker outputs a double-rail error indication, the compatibility with digital checkers is ensured and the design of self-checking mixed-signal circuits becomes very simple. The mixed-signal approach is extended toboards through the IEEE Std. 1149.1 digital test bus and a layout rule to avoid interconnect di erential shorts.
Training scholars in dissemination and implementation research for cancer prevention and control: A mentored approach
Abstract Background As the field of D&I (dissemination and implementation) science grows to meet the need for more effective and timely applications of research findings in routine practice, the demand for formalized training programs has increased concurrently. The Mentored Training for Dissemination and Implementation Research in Cancer (MT-DIRC) Program aims to build capacity in the cancer control D&I research workforce, especially among early career researchers. This paper outlines the various components of the program and reports results of systematic evaluations to ascertain its effectiveness. Methods Essential features of the program include selection of early career fellows or more experienced investigators with a focus relevant to cancer control transitioning to a D&I research focus, a 5-day intensive training institute, ongoing peer and senior mentoring, mentored planning and work on a D&I research proposal or project, limited pilot funding, and training and ongoing improvement activities for mentors. The core faculty and staff members of the MT-DIRC program gathered baseline and ongoing evaluation data regarding D&I skill acquisition and mentoring competency through participant surveys and analyzed it by iterative collective reflection. Results A majority (79%) of fellows are female, assistant professors (55%); 59% are in allied health disciplines, and 48% focus on cancer prevention research. Forty-three D&I research competencies were assessed; all improved from baseline to 6 and 18Â months. These effects were apparent across beginner, intermediate, and advanced initial D&I competency levels and across the competency domains. Mentoring competency was rated very highly by the fellowsââhigher than rated by the mentors themselves. The importance of different mentoring activities, as rated by the fellows, was generally congruent with their satisfaction with the activities, with the exception of relatively greater satisfaction with the degree of emotional support and relatively lower satisfaction for skill building and opportunity initially. Conclusions These first years of MT-DIRC demonstrated the programâs ability to attract, engage, and improve fellowsâ competencies and skills and implement a multicomponent mentoring program that was well received. This account of the program can serve as a basis for potential replication and evolution of this model in training future D&I science researchers
Paper and electronic versions of HM-PRO, a novel patient-reported outcome measure for hematology: an equivalence study.
© 2019 Goswami, Oliva, Ionova et al.Aim:To determine measurement equivalence of paper and electronic application of the hematologi-cal malignancy-patient-reported outcome (HM-PRO), a specific measure for the evaluation of patient-reported outcomes in HMs.Patients & methods:Following International Society of Pharmacoeconomicsand Outcomes Research ePRO Good Research Practice Task Force guidelines, a total of 193 adult patientswith different HMs were recruited into a multicenter prospective study. The paper and the electronic ver-sion of the instrument were completed in the outpatient clinics in a randomized crossover design with a30-min time interval to minimize the learning effect. Those who completed the paper version first, com-pleted the electronic version after 30 min and vice versa. Instrument version and order effects were testedon total score of the two parts of the HM-PRO (Part A: quality of life and Part B: signs & symptoms) in atwo-way ANOVA with patients as random effects. Intraclass correlation coefficients (95% CI) and Spear-manâs rank correlation coefficients were used to evaluate testâretest reliability and reproducibility. Theeffects of instrument version and order were tested on total score of the two parts of HM-PRO.Results:The questionnaire version and administration order effects were not significant at the 5% level. Therewere no interactions found between these two factors for HM-PRO (Part A [quality of life]; p=0.95); and(part B [signs and symptoms]; p=0.72]. Spearmanâs rank correlation coefficients were greater than 0.9, andintraclass correlation coefficients ranged from 0.94 to 0.98; furthermore, the scores were not statisticallydifferent between the two versions, showing acceptable reliability indexes. Noteworthy, the differencebetween the completion time for both paper (mean=6:38 min) and electronic version (mean=7:29 min)was not statistically significant (n=100; p=0.11). Patients did not report any difficulty in completing theelectronic version during cognitive interviews and were able to understand and respond spontaneously.Conclusion:Measurement equivalence has been demonstrated for the paper and electronic applicationof the HM-PRO.Peer reviewe
Global Impact of Local Educational Innovation
The innovation is carried out according to the demands or needs of
an industrial, social or economic sector and is aimed at the widest possible target
audience. In teaching educational innovation, the demand for innovation is very
local, it is generated in each subject and for the students of it. This causes that
educational innovation cannot be easily transferred between subjects. But, to
meet the demands of an educational sector, the target audience for which
innovation is designed must be global. The objective of this work is to study
whether teaching educational innovation can be considered globally (for a
global target audience and for a need in the education sector), so that it can be
applied and transferred between subjects from different contexts. The information
provided, during 8 training courses, by 130 university professors belonging
to 12 different universities has been analyzed. It has been shown that for a given
need for improvement (passive habit in students), the profile of the target
audience, the demand of the learning sector and the indicators to measure
educational innovation can be raised in a common way for an entire educational
sector; in this case, higher education. The conclusion is that educational innovation
can be designed globally, applied locally and transferred to other
contexts
Control of quantum interference in the quantum eraser
We have implemented an optical quantum eraser with the aim of studying this
phenomenon in the context of state discrimination. An interfering single photon
is entangled with another one serving as a which-path marker. As a consequence,
the visibility of the interference as well as the which-path information are
constrained by the overlap (measured by the inner product) between the
which-path marker states, which in a more general situation are non-orthogonal.
In order to perform which-path or quantum eraser measurements while analyzing
non-orthogonal states, we resort to a probabilistic method for the unambiguous
modification of the inner product between the two states of the which-path
marker in a discrimination-like process.Comment: Submitted to New Journal of Physics, March 200
