However, when a goal is difficult to extract from the visual scene, one can speculate that kinematics may be helpful to infer it.
Manual method of vehicle count is adopted as the turning movements of all vehicles are difficult to extract from a video.
In most cases, this information was also relatively difficult to extract from an article.
It is hypothesized that for Europe, the impact of site factors such as climate, texture and relief are difficult to extract from such a database if the data are only stratified according to macro-climatic areas.
However, it is difficult to extract from such an analysis the relationship between phage classification and specific phage properties as for example virion morphology.
This accounts for the lower total cell count in these wildfire PM-exposed lungs, suggesting that either the wildfire PM10 2.5 may be especially toxic to pulmonary alveolar macrophages or that these wildfire PM10 2.5 create a condition in which macrophages are difficult to extract from the lungs by lavage, perhaps because of enhanced adherence to alveolar surfaces.
The meat was difficult to extract from its shell under a heap of slippery sautéed sweet onions and a sprinkling of capers, and the deep-fried spinach leaves that accompanied it were very salty.
We show that important timing information associated with the interactions can be faithfully represented in autonomous Boolean models in which binary variables representing expression levels are updated in continuous time, and that such models can provide a direct insight into features that are difficult to extract from ordinary differential equation (ODE) models.
Additionally, due to the same complexity, it is difficult to extract from the closed-form solutions a mechanistic understanding of the neuron's resonant properties in terms of the time scales.
It was intensely difficult to extract from, partly because I'd had a few drinks, and also because I didn't want to irritate this man, or offend him, or make any kind of scene.
