The IMF's latest forecast revised down projections of global growth this year, but nonetheless predicted a better performance than in 2012.
The Committee for a Responsible Federal Government, one of Washington's most reliable deficit scolds, on Tuesday issued an analysis acknowledging that the ACA has helped to bring down projections of federal healthcare spending from 2011 to 2021 by $900 billion.
As the sun sets, fire-eaters breathe as the BMXers taste air, and once the sun is down, projections map the walls and stages, and lights resonate from the kids dancing with fluorescent hula hoops (this is a thing now).

Figure 3A shows the top down projection of the z-stack in the plane of the cantilever.
Instead active top-down projections continuously interact with earliest stages of sensory analysis.
First, we presume that powerful top-down projections are required to produce measurable influences at early latencies.
Importantly, "top-down" projections from the PFC can influence LPP responses; for example, Hajcak and Nieuwenhuis (2006) reported amplitude reduction when unpleasant stimuli were deliberately reappraised more positively.
Prediction error units compare predictions received from the higher level via backward, top-down projections and inputs received from the lower level via feedforward, bottom-up projections.
Top-down projections from the frontal eye field to visual area V4 can enhance stimulus-related activity, which emphasizes the importance of high level mechanisms [ 21, 25].
Larkum proposes a neuronal mechanism that integrates the long-distance top-down projections with bottom-up input, which involves layer 5 pyramidal cells that have distal tuft dendrites in layer 1.
This role is remarkably consistent with computational architectures in the cortex and thalamus: for example, top-down projections in the sensory hierarchies activate inhibitory neurons in layer 1 which then suppress (superficial) pyramidal cells, thought to encode prediction error (Shlosberg et al. 2006 ).

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
