摘要:Abstract(#br)The fast development of today’s healthcare and the need to extract new medical knowledge from exponentially-growing volumes of standardized Electronic Health Records data, as required by studies in Precision Medicine, brings up a challenge that may probably only...

摘要:Abstract(#br)The Western Antarctic Peninsula region shows mean annual air temperatures ranging from − 4 to − 2 °C. Due to its proximity to the climatic threshold of permafrost, and evidence of recent changes in regional air temperatures, this is a crucial area to analys...

摘要:Abstract(#br)Topography exerts a key role in controlling permafrost distribution in areas where mean annual temperatures are slightly negative. One such case is the low-altitude environments of Maritime Antarctica, where permafrost is sporadic to discontinuous below 20–40 m ...

摘要:Abstract(#br)The Mars Environmental Dynamics Analyzer (MEDA) is a suite of environmental sensors onboard NASA’s Mars 2020 mission. The Thermal InfraRed Sensor (TIRS), developed at Centro de Astrobiología of Spain, is one of the six sensors comprising MEDA, and it will measur...

摘要:Abstract(#br)In this paper we prove existence of least energy nodal solutions for the Hamiltonian elliptic system with Hénon-type weights − Δ u = | x | β | v | q − 1 v , − Δ v = | x | α | u | p − 1 u in Ω , ...

摘要:Abstract(#br)We study the existence, multiplicity and shape of positive solutions of the system − ε 2 Δ u + V ( x ) u = K ( x ) g ( v ) , − ε 2 Δ v + V ( x ) v = H ( x ) f ( u ) in R N , as ε → 0 . The functions f and g are power-like nonlinearities with superlinea...

摘要:Abstract(#br)We prove the existence of a nontrivial solution for a nonlinear elliptic problem − Δu = μu + a ( x ) g ( u ) with Dirichlet boundary condition on a bounded domain, where g is superlinear both at zero and at infinity, a ( x ) changes sign and μ >0.

摘要:Abstract(#br)We consider the ground state solutions of the Lane–Emden system with Hénon-type weights − Δ u = | x | β | v | q − 1 v , − Δ v = | x | α | u | p − 1 u in the unit ball B of R N with Dirichlet boundary conditions, where N ⩾ 1 , α , β ⩾ 0 , p , ...
