We consider the problem of minimizing a Lipschitz differentiable function over a class of sparse symmetric sets that has wide applications in engineering and science. For this problem, it is known that any accumulation point of the classical projected gradient (PG) method with a constant stepsize 1/L satisfies the L-stationarity optimality condition that was introduced in [3]. In this paper we ...
Scaling of the surface migration length in nanoscale patterned growth NPG is investigated as a function of the lateral dimension LM of a mask film fabricated on a substrate for selective epitaxy. By reducing LM below the surface migration length, any nucleation on the mask is avoided through the evaporation and surface out-diffusion of adatoms. The upper limit of LM for NPG LM,c corresponds to ...

A novel method to fabricate nanoporous gold (NPG) by chemical dealloying of electrodeposited AueSn
NPG film/Ni foam serves as the 3D hierarchical porous conductive
Nanoporous graphene (NPG) exhibits an apparent semiconductivity to solve the zero-gap problem of and also offers multifunctionalities that are directly associated with its structural chemical nature. However, reliable, low-cost, large-scale production NPG is a major challenge for practical applications. Here, high-performance resistive-switching memory cell based on biomass-derived materials de...
The unique bicontinuous porous structure and superior electrical conductivity of nanoporous gold (NPG) make it a highly promising material for energy storage conversion. Although the number articles on study NPG-based materials in fields has increased significantly recent years, collation review these are still lacking. Herein, we address this gap by reviewing research activities dealloyed NPG ...
Resumo Compreender a New Public Governance (NPG) como modelo de gestão vai ao encontro do atendimento às demandas atuais impostas pela sociedade administrações públicas, em que há necessidade envolver os cidadãos no processo decisório das políticas públicas. Com isso, numa perspectiva macro, gerar informações sobre evidenciação da NPG poderá contribuir para o desenvolvimento estratégias atendam...
Optic nerve degeneration caused by glaucoma is a leading cause of blindness worldwide. Patients affected by the normal-pressure form of glaucoma are more likely to harbor risk alleles for glaucoma-related optic nerve disease. We have performed a meta-analysis of two independent genome-wide association studies for primary open angle glaucoma (POAG) followed by a normal-pressure glaucoma (NPG, de...
INTRODUCTION Dermatitis herpetiformis (DH) seems to be a chronic immune-mediated inflammatory disease of partially known origin. In light of its known biological functions and its involvement in tissue pathology in other disease states, particularly in nickel-induced allergic contact dermatitis coexisting with DH, it would appear that the central and peripheral response by neutrophils and their...
