We introduce a definition of the fidelity function for multi-round quantum strategies, which we call the strategy fidelity, that is a generalization of the fidelity function for quantum states. We provide many interesting properties of the strategy fidelity including a Fuchs-van de Graaf relationship with the strategy norm. We illustrate an operational interpretation of the strategy fidelity in...

BACKGROUND Melanoma can metastasize but is often successfully treated when discovered in an early stage. Melanoma patients and their skin check partners can learn skin self-examination (SSE) skills and these skills can be improved by practice. The purpose of this study is to determine the degree of fidelity with which educational in-person SSE intervention can be delivered by trained research c...

UNLABELLED Mutagenic nucleoside analogues can be used to isolate RNA virus high-fidelity RNA-dependent RNA polymerase (RdRp) variants, the majority of which are attenuated in vivo. However, attenuated foot-and-mouth disease virus (FMDV) high-fidelity RdRp variants have not been isolated, and the correlations between RdRp fidelity and virulence remain unclear. Here, the mutagen ribavirin was use...

PURPOSE Treatment fidelity is a measure of the reliability of the administration of an intervention in a treatment study. It is an important aspect of the validity of a research study, and it has implications for the ultimate implementation of evidence-supported interventions in typical clinical settings. METHOD Aphasia treatment studies published in the last 10 years in 3 journals were revie...

In this paper, we present a new framework for analyzing and designing virtual reality (VR) techniques. This framework is based on two concepts – system fidelity (i.e., the degree with which real-world experiences are reproduced by a system) and memory (i.e., the formation and activation of perceptual, cognitive, and motor networks of neurons). The premise of the framework is to manipulate an as...

ethics are related to the structure and culture of the society. in addition to specialized ethics for every profession, individuals also hold their own personal beliefs and values. this study aimed to investigate iranian occupational therapists’ perception of ethical practice when working with children. for this purpose, qualitative content analysis was used and semi-structured interviews were ...

principlism, in general and four principles approach in particular is largely discussed in current medical ethics. accord­ing to principlism, the ethical relationship between physician and patient has to be categorized based on some princi­ples, the prin­ciples which are general, action-guiding and could help both the patient and the physician to arrange their ethical behav­ior. four principles...

OBJECTIVES Behavioral support for smoking cessation is delivered through different modalities, often guided by treatment manuals. Recently developed methods for assessing fidelity of delivery have shown that face-to-face behavioral support is often not delivered as specified in the service treatment manual. This study aimed to extend this method to evaluate fidelity of telephone-delivered behav...

BACKGROUND It is widely accepted that the highly error prone replication process of influenza A virus (IAV), together with viral genome assortment, facilitates the efficient evolutionary capacity of IAV. Therefore, it has been logically assumed that the enzyme responsible for viral RNA replication process, influenza virus type A RNA polymerase (IAV Pol), is a highly error-prone polymerase which...

The design of efficient flapping wings for human engineered micro aerial vehicles (MAVs) has long been an elusive goal, in part due to the large size of the design space. One strategy for overcoming this difficulty is to use a multi-fidelity simulation strategy appropriately balances computation time and accuracy. We compare two models with different geometric and physical fidelity. The low-fid...
