NE/SQP is a recent algorithm tha t has proven quite effective for solving the pure and mixed forms of the nonlinear complementarity problem (NCP). NE/SQP is robust in the sense that i ts direction-finding subproblems are always solvable; in addition, the convergence rate of this method is Q-quadratic.

Twenty-six cases of surgically verified nonchromaffin paragangliomas (NCPs) of the temporal bone were investigated by contrast-enhanced, thin-section, multiplanar high-resolution computed tomography (CT). Based on the high-resolution CT findings the tumors were classified according to a recently introduced surgical classification of NCP into four main types (A, B, C1-C3, and D1-D3). With high-r...

Mixed-layer dynamics exert a first order control on nutrient and light availability for phytoplankton. In this study, we examine the influence of mixed-layer net community production (NCP) in Southern Ocean intra-seasonal, seasonal, interannual, decadal timescales, using biogeochemical Argo floats satellite-derived NCP estimates during period from 1997 to 2020. On intraseasonal shoaling mixed l...

February 7, 1996 (Revised June 25, 1996) Abstract. Recently, Luo and Tseng proposed a class of merit functions for the nonlinear complementarity problem (NCP) and showed that it enjoys several interesting properties under some assumptions. In this paper, adopting a similar idea to Luo and Tseng's, we present new merit functions for the NCP, which can be decomposed into component functions. We s...

We provide a simple algebraic construction of the twistor spaces of arbitrary Joyce’s self-dual metrics on the 4-manifold H 2 × T 2 that extend smoothly to nCP, the connected sum of complex projective planes. Indeed, we explicitly realize projective models of the twistor spaces of arbitrary Joyce metrics on nCP in a CP-bundle over CP, and show that they contain the twistor spaces of H 2 × T 2 a...

In this paper, without assuming strict positivity of amplifier functions, boundedness of activation functions, or symmetry of the connection matrix, dynamical behaviors of delayed Cohen-Grossberg neural networks with nonnegative equilibria are studied. Based on the theory of the nonlinear complementary problem (NCP), a sufficient condition is derived guaranteeing the existence and uniqueness of...

Aim: This study aimed to investigate the relationship between severe novel coronavirus pneumonia (NCP) and hypercoagulable conditions that predispose patients thrombosis such as prothrombin gene ( F2) rs1799963 (G20210A), factor V Leiden F5) rs6025 (G1691A) PAI-1 (rs1799768). Patients: NCP-diagnosed 62 previously healthy were enrolled for investigation of thrombophilia-related polymorphisms. Ma...

The visibility in the Sichuan Basin (SB) was worse than that North China Plain (NCP) for same level of PM2.5. One well-known reason is aerosol extinction enhancement due to hygroscopic growth SB stronger NCP because relative humidity (RH) higher NCP. However, under PM2.5 and RH levels. volume efficiency (VEE) kept between 7 8 different SB, while VEE increased from 4.6 7.2 when 20 180 μg/m3 diff...

Analogous to the nonlinear complementarity problem (NCP) and the semidefinite complementarity problem (SDCP), a popular approach to solving the secondorder cone complementarity problem (SOCCP) is to reformulate it as an unconstrained minimization of a certain merit function over IR. In this paper, we present a descent method for solving the unconstrained minimization reformulation of the SOCCP ...
