The dilemma often concerns the influenza virus because it continually mutates, leading to human pandemics that predictably occur unpredictably.
IN the airline industry it is called the "Southwest effect," an explosion in passenger traffic at formerly sleepy, out-of-the-way regional airports that predictably occurs when Southwest, the industry's wildly successful discount-fare giant, comes to town.
Secondary seeding starts to predictably occur in modeled episodes when viral loads in a single ulcer exceed 10 HSV DNA copies.
In the idealized experimental system described in the present work, therapeutic failures predictably occurred when effector-to-target ratios were insufficient in vivo.
It predictably occurs at bifurcations, side branches, and opposite flow dividers at areas of low endothelial shear stress and turbulent blood flow.
So-called "sunny day flooding", (i.e tidal flooding or flooding that occurs without the rain) is already occurring predictably in many parts of Miami, inundating streets, blocking traffic, killing lawns, corroding infrastructure and cars, contaminating groundwater, and reversing sewage systems.
Pelagic protected areas are likely to be particularly effective where species occur predictably at some point in time and management can reflect this predictability.
Predictably, the episode occurred in Paris.
While salinity stress occurs predictably every year in the roadside, freezing and drought occur randomly, depending on climatic conditions.
An immediate question is how and why certain developmental events occur predictably while others appear to be random.
