Let A, B ⊆ Z be finite, nonempty subsets such that maxB − minB ≤ maxA − minA, gcd(A+B−c) = 1, for some c ∈ A+B, and |A+B| ≤ |A|+2|B|−3−δ(A,B), where δ(A,B) is 1 if x + A ⊆ B for some x ∈ Z, and is 0 otherwise. Assume one of the following conditions holds true: • maxA−minA ≤ |A| + |B|− 3, • gcd(A− a) ≤ 2, for some a ∈ A, • |A + B| ≤ 2|A| + |B|− 3− δ(B,A). Then A+B contains a (|A|+ |B|−1)–term ar...

Recent findings Recently published preoperative fasting guidelines for pediatric patients are covered along with studies comparing gastric volume following different fasting intervals. Pediatric obstructive sleep apnea is discussed. Clinical presentation, severity, perioperative risks, and controversies as whether outpatient procedures are suitable for these patients are presented. New data cov...

Many fault-detection problems fall into the following model: There is a set of n items, some of which are defective. The goal is to identify the defective items by using the minimum number of tests. Each test is on a subset of items and tells whether the subset contains a defective item or not. Let Ma(d, n)(M(d In)) denote the maximum number of tests for an algorithm ot to identify d defectives...
