In this letter, we report metal-enhanced e-type fluorescence. Eosin in close proximity to silver island films (SiFs) shows enhanced e-type fluorescence with an approximately two-fold higher intensity observed from SiFs, as compared to a control sample. Our findings suggest two complementary mechanisms for the enhancement: surface plasmons can radiate e-type delayed fluorescence efficiently and ...

A recently developed peridynamic (PD) shell model based on the ordinary state-based theory is adopted to evaluate stress intensity factors (SIFs) under in-plane loading. Strain and components are obtained by introducing differential operator. In order mixed-mode SIFs, domain form of interaction integral employed. The adaptive dynamic relaxation technique utilized obtain steady-state solutions, ...

This paper examines the design of social investment funds (SIFs) and explores the ways they affect agents’ incentives to propose, select, and implement good projects. Compared with other forms of decentralized service provision, SIFs possess features of administratively delegated authority and deep political devolution. Where existing political institutions fail to deliver assistance to vulnera...

In this paper, we report the first observation of metal-enhanced S(2) emission at room and low temperature (77K). The S(2) emission intensity of Azulene is enhanced by close proximity to Silver island films (SiFs). In this regard, a ≈ 2-fold higher S(2) fluorescence intensity of Azulene was observed from SiFs as compared to a glass control sample. This suggests that S(2) excited states can coup...

In this letter, we report the first observation of metal-enhanced excimer (P-type) fluorescence from pyrene. Pyrene in close proximity to silver island films (SIFs) shows enhanced pyrene excimer emission with a approximately 2.5-fold higher emission intensity observed from SIFs and 5x10(-3) M pyrene, as compared to a quartz control sample containing no silver nanoparticles. Our findings suggest...

Research has overwhelmingly supported the proposition that safe injection facilities (SIFs) are successful in meeting their stated objectives. However, the methodological and analytic approaches used in these studies have not been scrutinized to any significant degree. Previous studies are compromised by an array of deficiencies, including a lack of baseline data, insufficient conceptual and op...

This paper explores a possible way in which strategic asset allocation decision-making processes can suitably exploit Social Impact Investments (SIIs). We focus on the role that SIIs play context of variance-minimizing investments. To this aim, we employ an index tracks companies' financial performance. A hand-collected sample Firms (SIFs) is basis empirical experiments. Our results point out t...

An advanced boundary element method (BEM) with thin-body capabilities was developed recently for the study of interphases in ®ber-reinforced composite materials (Y.J. Liu, N. Xu and J.F. Luo, Modeling of interphases in ®berreinforced composites under transverse loading using the boundary element method, ASME J. Appl. Mech. 67 (2000) 41±49). In this BEM approach, the interphases are modeled as t...
