We consider the implications of experimental limits on the permanent electric dipole moment (EDM) of the electron and neutron for possible new timereversal violating (TV) parity-conserving (PC) interactions. We show that the constraints derived from one-loop contributions to the EDM exceed previously reported two-loop limits by more than an order of magnitude and imply a lower bound on the new ...

Numerical simulations are fundamental to the development of medical imaging systems because they can save time and effort in research and development. In this study, we developed a method of creating the virtual projection images that are necessary to study dedicated breast computed tomography (BCT) systems. Anthropomorphic software breast phantoms of the conventional compression type were synt...

OBJECTIVES To explore healthcare professionals' views of antibiotic prescribing in long-term care facilities (LTCFs). To use the findings to recommend intervention strategies for antimicrobial stewardship in LTCFs. DESIGN Qualitative semistructured interviews were conducted. The data were analysed by thematic content analysis. After the interviews, the emerging findings were mapped to the the...

PURPOSE The purpose of this study was to measure the degree to which informed women chose mastectomy, and to reveal their reasons for this choice. PATIENTS AND METHODS This was a prospective cohort study of patients radiographically and pathologically eligible for either mastectomy or breast-conserving surgery (BCS; n = 125). Participants completed questionnaires at three time points: baselin...

PURPOSE Skin is a major organ at risk in breast-conserving therapy (BCT). The American Brachytherapy Society (ABS) recommendations require monitoring of maximum dose received, however, there is no unambiguous way of skin contouring provided. The purpose of this study was to compare the doses received by the skin in different models. MATERIAL AND METHODS Standard treatment plans of 20 patients...

Breast surgery currently remains very subjective and each intervention depends on the ability and experience of the operator. To date, no objective measurement of this anatomical region can codify surgery. In this light, we wanted to compare and validate a new technique for 3D scanning (LifeViz 3D) and its clinical application. We tested the use of the 3D LifeViz system (Quantificare) to perfor...

The Korean Breast Cancer Society collected and formulated data for breast cancer in Korean through the nation-wide survey in 1998. The purposes of the present study were to determine the characteristics of breast cancer patients and compare these data with those from other countries. The data were collected from 36 university hospitals and 41 training hospitals. The total number of patients was...
