Abstract:
Cardiac papillary fibroelastoma is a rare benign cardiac tumor that represents less than 10% of all cardiac tumors. Most papillary fibroelastomas are relatively small. Symptoms, if present, are due to flow obstruction or peripheral embolization. The most common sites of origin are aortic and mitral valve surfaces. We present successful surgical resection of a papillary fibroelastoma through the mitral valve which originated from the posterior papillary muscle of the left ventricle.

Unusual Results
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.
Maximum unusual value =...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
