Heritability of circle of Willis variations in families with intracranial aneurysms.

Intracranial aneurysms more often occur in the same arterial territory within families. Several aneurysm locations are associated with specific circle of Willis variations. We investigated whether the same circle of Willis variations are more likely to occur in first-degree relatives than in unrelated individuals.

The combination of circle topology and leaky integrator neurons remarkably improves the performance of echo state network on time series prediction.

Recently, echo state network (ESN) has attracted a great deal of attention due to its high accuracy and efficient learning performance. Compared with the traditional random structure and classical sigmoid units, simple circle topology and leaky integrator neurons have more advantages on reservoir computing of ESN. In this paper, we propose a new model of ESN with both circle reservoir structure and leaky integrator units. By comparing the prediction capability on Mackey-Glass chaotic time series of four ESN...

A Nurse-Led Innovation in Education: Implementing a Collaborative Multidisciplinary Grand Rounds.

Multidisciplinary grand rounds provides an opportunity to promote excellence in patient care through scholarly presentations and interdisciplinary collaboration with an innovative approach. In addition, multidisciplinary grand rounds serves to recognize expertise of staff, mentor and support professional development, and provide a collaborative environment across all clinical disciplines and support services. This article describes a process model developed by nurse educators for implementing a multidiscipl...

Basilar Artery Diameter Is Inversely Associated with Fetal Type Circle of Willis.

The relationship between basilar artery (BA) diameter and Circle of Willis (CoW) configuration has been scarcely investigated. We aimed to assess this association in community-dwelling older adults.

Modular Invariance of Conformal Field Theory on S^{1}×S^{3} and Circle Fibrations.

I conjecture a high-temperature-low-temperature duality for conformal field theories defined on circle fibrations like S^{3} and its lens space family. The duality is an exchange between the thermal circle and the fiber circle in the limit where both are small. The conjecture is motivated by the fact that π_{1}(S^{3}/Z_{p→∞})=Z=π_{1}(S^{1}×S^{2}) and the Gromov-Hausdorff distance between S^{3}/Z_{p→∞} and S^{1}/Z_{p→∞}×S^{2} vanishes. Several checks of the conjecture are provided: free field...

Self-Determination Theory as a Foundation for Personality Researchers.

In this introductory article we first describe the impetus for this special issue. What made us think that Self-Determination Theory (SDT) might provide a sort of foundation for the rest of personality psychology? For readers unfamiliar with SDT, we then provide a historical overview which covers the evolution of the six "mini-theories" that currently comprise SDT: cognitive evaluation theory, causality orientations theory, organismic integration theory, basic psychological needs theory, goal contents theor...

Experience with Event Timing Does not Alter Emergent Timing: Further Evidence for Robustness of Event and Emergent Timing.

Although, event and emergent timings are thought of as mutually exclusive, significant correlations between tapping and circle drawing (Baer, Thibodeau, Gralnick, Li, & Penhune, 2013 ; Studenka, Zelaznik, & Balasubramaniam, 2012 ; Zelaznik & Rosenbaum, 2010 ) suggest that emergent timing may not be as robust as once thought. We aimed to test this hypothesis in both a younger (18-25) and older (55-100) population. Participants performed one block of circle drawing as a baseline, then six blocks of tapping, f...

The Singapore Sling: F1 Race Team Cognitive Function and Mood Responses During the Singapore Grand Prix.

The current investigation measured cognitive performance, subjective ratings of mood and sleep in Formula 1® (F1) race team members during the 2013 Singapore Grand Prix. Two weeks prior to the Singapore Grand Prix participants (n = 16; mean age 33.5 years, range 22-48 years) underwent baseline cognitive assessments as well as a questionnaire on mood and sleep quality/duration. These assessments were repeated on the race weekend prior to practice (S1) and post qualifying (S2). A significant increase in simp...

Pathways for Theoretical Advances in Visualization.

There is little doubt that having a theoretic foundation will benefit the field of visualization, including its main subfields. Because there has been a substantial amount of work on taxonomies and conceptual models in the visualization literature and some recent work on theoretic frameworks, such a theoretic foundation is not a foolish or impractical ambition. This article asks, "How can we build a theoretic foundation for visualization collectively as a community?" The authors envision the pathways for fo...

Proportion of women presenters at medical grand rounds at major academic centres in Canada: a retrospective observational study.

To assess the proportion of women who presented research or medical grand rounds at five major academic hospitals in Canada.

The association of the circle of Willis anomaly and risk of stroke in patients with carotid artery disease.

In this retrospective study, we analyzed 175 patients who presented at our outpatient stroke clinic between January, 2013 and June, 2015 with either unilateral symptomatic or asymptomatic carotid artery disease, and who had had CT angiography imaging performed. Demographic properties, carotid artery stenosis and the anomaly of the circle of Willis was recorded.

Safety of perioperative cerebral oxygen saturation during debranching in patients with incomplete circle of Willis.

The consequences of common carotid artery (CCA) cross-clamping during debranching before thoracic endovascular aortic repair are unclear. We examined the safety of a simple CCA cross-clamping procedure under regional cerebral oxygen saturation monitoring (rSO2) in patients with a complete or incomplete circle of Willis (CoW) anatomy.

Analysing a cycling grand tour: Can we monitor fatigue with intensity or load ratios?

This study evaluated the changes in ratios of different intensity (rating of perceived exertion; RPE, heart rate; HR, power output; PO) and load measures (session-RPE; sRPE, individualized TRIMP; iTRIMP, Training Stress Score™; TSS) in professional cyclists. RPE, PO and HR data was collected from twelve professional cyclists (VO2max 75 ± 6 ml∙min∙kg(-1)) during a two-week baseline training period and during two cycling Grand Tours. Subjective:objective intensity (RPE:HR, RPE:PO) and load (sRPE:iTR...

Comments on Minisola et al.: Correction of vitamin D status by calcidiol: pharmacokinetic profile, safety, and biochemical effects on bone and mineral metabolism of daily and weekly dosage regimens.

Replica exchange and standard state binding free energies with grand canonical Monte Carlo.

The ability of grand canonical Monte Carlo (GCMC) to create and annihilate molecules in a given region greatly aids the identification of water sites and water binding free energies in protein cavities. However, acceptance rates without the application of biased moves can be low, resulting in large variations in the observed water occupancies. Here, we show that replica exchange of the chemical potential significantly reduces the variance of the GCMC data. This improvement comes at a negligible increase in ...

The SDM 3 Circle Model: A Literature Synthesis and Adaptation for Shared Decision Making in the Hospital.

Patient engagement through shared decision-making (SDM) is increasingly seen as a key component for patient safety, patient satisfaction, and quality of care. Current SDM models do not adequately account for medical and environmental contexts, which may influence medical decisions in the hospital. We identified leading SDM models and reviews to inductively construct a novel SDM model appropriate for the inpatient setting. A team of medicine and pediatric hospitalists reviewed the literature to integrate cor...
