X-ray computed tomography is a noninvasive imaging modality capable of reconstructing exact density values of 3D objects. Computed tomography machines are deployed across the world to provide doctors with an image that reveals more detail than a standard x-ray image. We investigate algorithms based on exact computed tomography reconstruction formulas...
Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations.

It is likely attributable mostly to the improved sampling of SST observations...

Many parents want their children to have positive feelings about themselves and to believe they can succeed. Children often evaluate their selfworth and make judgments about their abilities based on experiences they have at home. Families can provide numerous
opportunities every day to develop children’s self-confidence.
Why is problem solving important for families? Naturally, conflicts arise
for children every day. Children who learn to figure out solutions
to their problems are better able to work and play with others. The
ability to solve difficult situations also builds positive self-esteem,
self-confidence, and relationships with others.
