Intervention Fidelity of Telephone Motivational Interviewing On Physical Activity, Fruit Intake, and Vegetable Consumption in Dutch Outpatients With and Without Hypertension

Background In theory, Motivational Interviewing (MI) fidelity should be associated with client outcomes. Nevertheless, this fidelity-effectiveness association is rarely investigated. This study evaluated the extent to which Telephone Motivational Interviewing (TMI) fidelity is associated with change in self-reported physical activity (PA), fruit...

Hard superconducting gap in germanium

The co-integration of spin, superconducting, and topological systems is emerging as an exciting pathway for scalable and high-fidelity quantum information technology. High-mobility planar germanium is a front-runner semiconductor for building quantum processors with spin-qubits, but progress with hybrid superconductor-semiconductor devices is...

Measuring Implementation of Health Promoting School (HPS) Programs: Development and Psychometric Evaluation of the HPS Implementation Questionnaire

Background: Implementation of Health Promoting School (HPS) programs can be challenging due to the dynamic school context. Navigating between program fidelity and adaptation, as well as integrating the program, is essential for successful implementation, and consequently, for program effects. As part of an evaluation study in the Netherlands,...

Imperfect Distributed Quantum Phase Estimation

Fast, High-Fidelity Conditional-Phase Gate Exploiting Leakage Interference in Weakly Anharmonic Superconducting Qubits

Conditional-phase (cz) gates in transmons can be realized by flux pulsing computational states towards resonance with noncomputational ones. We present a 40 ns cz gate based on a bipolar flux pulse suppressing leakage (0.1%) by interference and approaching the speed limit set by exchange coupling. This pulse harnesses a built-in echo to enhance...

Embedding silicon spin qubits in superconducting circuits

We demonstrate the strong coupling between a single electron spin in silicon and a single photon in a superconducting microwave cavity. Using the same cavity we perform rapid high-fidelity single-shot readout of two-electron spin states.

Virtual characters that work: fit-for-purpose behavior of virtual entities in training simulations

Realizing the potential of simulation for training demands that virtual players (the Non Playing Characters, or NPCs) behave in a believable fashion and in conjunction with the training objectives. To demonstrate ‘fit-for-purpose realism’, an NPC should adhere to relevant protocols, norms and values of the situational context (“believability”),...

Wi-5: A Programming Architecture for Unlicensed Frequency Bands

We present Wi-5, a spectrum programming architecture for radio resource management in unlicensed frequency bands. It introduces a spectrum control plane that offers fine grained allocation of radio resources, flexible configuration of radio and wireless networking parameters, and continuous monitoring of the wireless network status. These...

Reliably Assessing the Effectiveness of a Plan Using Models of Varying Fidelity and Under Time Constraints

Assessing the effectiveness of a plan, given multiple potential scenarios, is a common problem for analysts, especially in the military domain. This problem can seriously impact the safety of the people that are involved in planned missions. More precisely, the availability of multiple models, with varying levels of fidelity, leads to the...

Modelling environmental and cognitive factors to predict performance in a stressful training scenario on a naval ship simulator

Professionals working in risky or emergency situations have to make very accurate decisions, while the quality of the decisions might be affected by the stress that these situations bring about. Integrating task feedback and biofeedback into computer-based training environments could improve trainees’ stress-coping behaviour. This paper presents...

Is the process of delivery of an individually tailored lifestyle intervention associated with improvements in LDL cholesterol and multiple lifestyle behaviours in people with Familial Hypercholesterolemia?

Background: More insight in the association between reach, dose and fidelity of intervention components and effects is needed. In the current study, we aimed to evaluate reach, dose and fidelity of an individually tailored lifestyle intervention in people with Familial Hypercholesterolemia (FH) and the association between intervention dose and...

Pilot motion perception and control during simulated decrab maneuver

A set of experiments were conducted on the National Aerospace Laboratory (NLR) GRACE research flight simulation facility to determine the effects of sway, yaw and roll motion on perceived motion fidelity, motion perception, pilot workload and pilot compensation. Fourteen pilots were asked to perform a manual decrab maneuver when the aircraft was...

Fidelity Assessment within the REVVA Generic Process

The REVVA methodology, developed in the WEAG THALES Joint Program 11.20, provides a framework for verification and validation activities resulting in an acceptance recommendation for data, models and simulations. The core of the methodology is the decomposition of the 'intended purpose' into acceptability criteria (AC). The V&V effort focuses on...

Objective assessment of simulated daytime and NVG image fidelity

Synthetic imagery used for training and evaluating visual search and detection tasks should result in the same observer performance as obtained in the field. The generation of synthetic imagery generally involves a range of computational approximations and simplifications of the physical processes involved in the image formation, in order to...

What's crucial in night vision goggle simulation ?

Training is required to correctly interpret NVG imagery. Training night operations with simulated intensified imagery has great potential. Compared to direct viewing with the naked eye, intensified imagery is relatively easy to simulate and the cost of real NVG training is high (logistics, risk, civilian sleep deprivation, pollution). On the...

Motion fidelity during a simulated takeoff

In this psychophysical study, seven airline pilots reported on their perceived self-motion in response to variations of motion filter gains during a simulated takeoff. Each pilot participated both as pilot flying and pilot non-flying. In order to vary the gains of the simulated linear acceleration and the rotation independently, a "direct pitch"...

A new universal colour image fidelity metric

We extend a recently introduced universal grayscale image quality index to a newly developed perceptually decorrelated colour space. The resulting colour image fidelity metric quantifies the distortion of a processed colour image relative to its original version. We evaluated the new colour image fidelity metric through observer experiments in...
