We propose and experimentally demonstrate a new plasmonic nonlinear light generation (NLG) structure, termed plasmonic-enhanced, charge-assisted second-harmonic generator (p-CASH), that not only achieves high second-harmonic generation (SHG) enhancement (76-fold), large SHG tunability by bias (8%/V), wide tuning range (280%), 7.8 × 10(-9) conversion efficiency, and high stability but also exhib...

Recently, environmental concern and demand for a catalyst’s high performance have increased and many research activities focused on the operation of a three-way catalyst (TWC) at the end of its lifetime. Catalyst aging is the loss of catalytic activity over time that has crucial importance in emission of three-way catalyst.  The aim of this paper is, investigating experimentally the performanc...

The paper aims to investigate the effects of COVID-19 pandemic on working capital management policies among Polish small and medium-sized enterprises operating in Group Purchasing Organizations (GPOs). results show that firms adopted a moderate–conservative strategy for their management.

Purpose: Prior studies show that inventory holding is closely linked to liquidity and procyclical dependent on the combination of macroeconomic firm characteristics. Thus, conditional linear factor models such as OLS should fail explain inventory-holding motive, especially in context developing countries. This study seeks empirically investigate determinants corporate based evidence from pharma...

We empirically examine how governance structure affects the design of executive compensation contracts and, in particular, the implicit weights of firm performance measures in CEO compensation. We find that compensation contracts in firms with higher takeover protection and where the CEO has more influence on governance decisions put more weight on accounting-based measures of performance (retu...

The uniform-price auction is used in many regional electricity procurement auctions and its “collusive-seeming equilibria” have been linked to potential exercise of market power. Such equilibria do not exist, however, if a small amount of cash is split among rationed bidders. To shed light on what drives this result, I also examine variations in which the auctioneer is able to increase and/or d...

This paper empirically examines whether additional future fixed capital and R&D investment expenditures induce firms to accumulate cash reserves while considering the role of market imperfections. Implementing a dynamic framework on a panel of US, UK and German companies, we find that firms make larger additions to cash holdings when they plan additional future R&D rather than fixed capital inv...

The environment is the source of many discussions in America’s board rooms. Most of the conversations probably center around cost containment, dealing with new regulations or reacting to unexpected problems. Some conversations may even revolve around how to “cash in” on the public’s concern for the environment. All of these discussions are normal, but also are increasingly becoming outdated. Co...

Merchants operations involves valuing and hedging the cash flows of commodity and energy conversion assets as real options based on stochastic models that inevitably embed model error. In this paper we quantify how empirically calibrated model errors about the futures price term structure affect the valuation and hedging of commodity storage assets, specifically the storage of natural gas, an i...
