in this study, the optimization of energy consumption and reduction of greenhouse gas emissions of irrigated lentil production in esfahan province were conducted using data envelopment analysis (dea) method. the used data were collected randomly from 140 lentil producers using a face to face questionnaire method in the cropping season of 2014-2015. based on two dea models of constant returns to...

The Entrepreneurial Ecosystems (EE) approach makes specific predictions regarding how EE inputs are converted into high-growth firms (HGFs) as an output. A simulation model draws out our hypothesis of regional persistence in HGF shares. Based on intuitions that EEs persistent, we investigate whether shares using census data for 2 European countries taken separately (Croatia 2004–2019, and Slove...

We study the combined effects of uncertainty and competition on the timing optimization of investments in complementarity inputs for non-preemption duopoly (leader-follower) markets with either a weakpatent system where spillover-knowledge is allowed or a strong-patent system where proprietaryknowledge holds. We find that, for some input-sequencing investment scenarios, ex-ante and (expected) e...

This paper investigates the effect of economic sanctions on employment. We exploit imposition a series unexpected and unprecedented international Iran in 2012 estimate short-run effects change import exposure manufacturing employment at industry level. Our estimates indicate that led to an overall decline growth rate by 16.4 percentage points. However, we uncover significant asymmetric across i...

Area CA2 is emerging as an important region for hippocampal memory formation. However, how CA2 pyramidal neurons (PNs) are engaged by intrahippocampal inputs remains unclear. Excitatory transmission between CA3 and CA2 is strongly inhibited and is not plastic. We show in mice that different patterns of activity can in fact increase the excitatory drive between CA3 and CA2. We provide evidence t...

The visual cryptography scheme (VCS) is a scheme which encodes a secret image into several shares, and only qualified sets of shares can recover the secret image visually, other sets of shares cannot get any information about the content of the secret image. From the point of view of encrypting (carrying) the secret information, the traditional VCS is not an efficient method. The amount of the ...
