Borrowing a page from the protein structure prediction community, we propose a periodic challenge program to vet the most promising methods in the field, and to foster the collective development of useful tools and algorithms.
Kidd, who is entering his first season as a coach after a 19-year playing career, has high expectations for Williams, using interviews with the news media to issue periodic performance challenges.
I term this novel technique coherent hemodynamics spectroscopy (CHS), and this article describes how it can be used for the assessment of cerebral autoregulation and the study of hemodynamic oscillations resulting from a variety of periodic physiological challenges, brain activation protocols, or physical maneuvers.
Also, we conducted an otherwise identical control experiment, where a subset of the clones (6 robust, 6 brittle) were allowed to evolve using a periodic temperature challenge of the standard 25°C environment.
However, this same distance characteristic may be a challenge for periodic servicing mission.
Nanosphere lithography is one popular bottom-up fabrication technique where nanosized spheres are assembled to form periodic structures, yet it is challenging to form a uniform monolayer sphere for sub-100 nm sphere size [13].
Even as it struggles with challenges such as flooding, periodic cyclones and widespread malnutrition, Madagascar is working to transform its subsistence economy into a market economy.
(Note: Unlike most everyone else who was affected, I looked forward to labor negotiations, strikes and lockouts. They provided a periodic change of pace and a challenge to report them).
On the contrary, atypical PFAPA and other kinds of periodic fever can be a diagnostic challenge, even for experienced physicians.
