Pairing Heaps with Costless Meld
Improving the structure and analysis in [1], we give a variation of the pairing heaps that has amortized zero cost per meld (compared to an O(log log n) in [1]) and the same amortized bounds for all other operations. More precisely, the new pairing heap requires: no cost per meld, O(1) per find-min and insert, O(log n) per delete-min, and O(log log n) per decrease-key. These bounds are the best...
متن کاملLiver Transplantation in Patients with Portal Vein Thrombosis: Comparing Pre-MELD and MELD era
BACKGROUND Portal vein thrombosis (PVT) used to be a relative contraindication for liver transplantation (LT). This obstacle has been dealt with following the improvement of LT-related techniques. OBJECTIVE To compare the outcome of adult patients with PVT who underwent LT before and after adopting MELD. METHODS We retrospectively searched our database for deceased donor LT recipients who h...
متن کاملAddition of serum sodium into the MELD score predicts waiting list mortality better than MELD alone.
In this study, we investigated the prognostic value of serum sodium and hyponatremia (< or =130 mEq/L) in 262 cirrhotic patients consecutively listed, 19 of which died (7%), 175 survived (67%), and 68 underwent liver transplantation (26%) during 3 months of follow-up. Hyponatremia was present in 63% of patients who died, compared to 13% of those who survived (P < .001), whereas the proportion w...
متن کاملThe MELD Score: Limitations and consequences
-The success of liver transplantation has created unexpected challenges for physicians and surgeons caring for patients with chronic liver disease or acute liver failure. Specifically, with all of these legitimate candidates for liver transplantation, how does one prioritize them given the unfortunate issue of limited donor availability? The answer to that problem has undergone several iteratio...
متن کاملMELD: Mixed effects for large datasets
Mixed effects models provide significant advantages in sensitivity and flexibility over typical statistical approaches to neural data analysis, but mass univariate application of mixed effects models to large neural datasets is computationally intensive. Threshold free cluster enhancement also provides a significant increase in sensitivity, but requires computationally-intensive permutation-bas...
