A long-term goal of AI is to produce agents that can learn a diversity of skills throughout their lifetimes and continuously improve those skills via experience.A longstanding obstacle towards that goal is catastrophic forgetting, which is when learning new information erases previously learned information.Catastrophic forgetting occurs in artifici
The Festuca Cutlery Cylinders genus is thought to be the most numerous genus of the Poaceae family.One of the most agronomically important forage grasses, Festuca pratensis Huds.is treated as a model plant to study the molecular mechanisms associated with tolerance to winter stresses, including frost.However, the precise mapping of the genes govern
Glacier-bed characteristics that are poorly known and modeled are important in projected sea-level rise from ice-sheet changes under strong warming, especially in the Thwaites Glacier drainage of West Antarctica.Ocean warming may induce ice-shelf thinning Gauze or loss, or thinning of ice in estuarine zones, reducing backstress on grounded ice.Mode
Introduction: Cholera is a highly contagious disease that causes severe diarrhea and dehydration.This study investigated podophyllotoxin, deoxypodophyllotoxin, and ursolic acid as inhibitors of tcpA, ompW, and ctxB genes in Vibrio cholerae.Methods: We obtained the crystallized structure of podophyllotoxin, deoxypodophyllotoxin, and ursolic acid fro
Let q > r ≥ 1 be coprime integers.Let P c = P c ( q , r , H ) be an increasing sequence of primes p satisfying two conditions: (i) p ≡ r (mod q) and (ii) p starts a prime k-tuple with a given pattern H.Let π c ( x ) be the number of primes in P c not exceeding x.We heuristically derive formulas predicting the growth trend of the
