Advances in Difference Equations, 2018 In this paper we consider the existence of positive solutions of nth-order Sturm–Liouville boundary value problems with fully nonlinear terms, in which the nonlinear term f involves all of the derivatives u′,…,u(n−1) $u',\ldots, u^{(n-1)}$ of the unknown

AIMS MathematicsIn this paper, we propose a kind of partial symmetric regularized alternating direction method of multipliers for solving non-convex split feasibility problems. This algorithm adds an update to the Lagrangian multiplier term during the iteration process.

The dynamics of criminal collaboration: Multiplex ties in mafia networks
Criminology, EarlyView.Abstract This study examines how social embeddedness and multiplex relationships shape criminal collaboration within organized crime networks. Drawing on data from three major investigations into the ‘Ndrangheta, we analyze how kinship, clan affiliation, leadership, and prior interactions influence participation in meetings and phone calls.

Artificial Organs, EarlyView.Graphical summary of the experimental comparison of shear‐induced hemolysis in pediatric and adult blood using a Couette shearing device. Pediatric blood shows a trend toward lower increase in hemolysis at higher shear stress amplitudes, while no relevant differences are observed at low and intermediate stresses.

Block scheduling in practice: An optimal decomposition strategy for nonidentical operating rooms
Decision Sciences, EarlyView.Abstract We develop and implement a Master Surgery Schedule for a real‐life hospital, assigning operating room (OR) time to surgical specialties over a multi‐week horizon. Through action research, we identify a critical operational challenge: the issue of split blocks. Split blocks allow two specialties to share an OR on the same day—one in the morning,

Multiplicity of solutions for quasilinear elliptic boundary-value problems
Electronic Journal of Differential Equations, 1999 This paper is concerned with the existence of multiple solutions to the boundary-value problem $$-(varphi_p(u') ) '=lambda varphi_q(u) +f(u)quadhbox{in } (0,1),,quad u(0) =u(1) =0,,$$ where $p,q>1$, $varphi_x(y) =|y|^{x-2}y$, $lambda $ is a real ...

Two laws of large numbers for sublinear expectations
, 2015 In this paper, we consider the sublinear expectation on bounded random vari- ables. With the notion of uncorrelatedness for random variables under the sublinear expectation, a weak law of large numbers is obtained.

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)
Journal of Systematics and Evolution, EarlyView.Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.
