The relation between morbid obesity, serious morbidity, and early mortality is well known (fig 1 and table 1).1 2 A recent systematic review of over 890 000 participants found that each 5 point increase in body mass index (kg/m2) over 25 was associated with a 30% increase in overall mortality.3 Conservative approaches to managing obesity (dieting, exercise, and cognitive behavioural therapy) ac...

We present a new method to compute upper bounds of the number of solutions of binary integer programming (BIP) problems. Given a BIP, we create a dynamic programming (DP) table for a redundant knapsack constraint which is obtained by surrogate relaxation. We then consider a Lagrangian relaxation of the original problem to obtain an initial weight bound on the knapsack. This bound is then refine...

born and adult are presented in Table I, both on a fresh-weight and a fat-free fresh weight basis. The latter basis for express ing values avoids discrepancies that arise because of alterations in fat content. It is evident that signfficant changes in body composition occur during growth. Water, sodium, and chloride contents decline, while contents of nitrogen, calcium, potas sium, magnesium an...

Tables on the Web contain a vast amount of knowledge in structured form. To tap into this valuable resource, we address problem table retrieval: answering an information need with ranked list tables. We investigate two different variants, based how is expressed: as keyword query or existing (“query-by-table”). The main novel contribution work semantic retrieval framework for matching needs (key...
