Transpiration: how many functions?

How many patients? How many doctors?

O ne of the fastest growing fields in medicine is the care of adults with congenital heart disease (adult CHD or ACHD). This is mainly a consequence of much longer survival due to advances in pediatric cardiology, interven-tional catheterization, cardiac surgery, and intensive care. Fifty years ago we could diagnose most forms of moderate and severe CHD, but some anomalies were untreatable and ...

Insulators: many functions, many mechanisms.

HOW MANY FACTORS ? 1 Question Number Two : How Many Factors ?

Exploratory factor analysis involves five key decisions. The second decision, how many factors to retain, is the focus of the current paper. Extracting too many or too few factors often leads to devastating effects on study results. The advantages and disadvantages of the most effective and/or most utilized strategies to determine the number of factors to extract will be explored. Equipped with...

How Many Distribution Functions Are There? Bracketing Entropy Bounds for High Dimensional Distribution Functions

This means that every F ∈ Fd satisfies: (i) (non-negativity). For finite intervals I = (a1, b1] × · · · × (ad, bd] ≡ (a, b], with a, b ∈ Rd, F (I) = ∆dF (a, b] ≥ 0 where ∆d denotes the d−dimensional difference operator. (ii) (continuity from above). If y ↓ x, then F (y) ↓ F (x). (iii) (normalization). If x1∧. . .∧xd → −∞, then F (x) → 0; if x1∧. . .∧xd → +∞, then F (x) → 1. (See Billingsley [4]...

How Many Psychiatrists?

major assessment, and in most cases later interviews are of only fifteen minutes' duration. A few patients can be, and are, seen for longer sessions, but this is bound to lead to more widely spaced interviews for others or to longer waiting lists for the first assessment, as the volume of outpatient work has been and is rising rapidly. There are a comparatively small number of psychotherapists,...
