Over the last few years the efficiency of search equilibria has been examined by a number of authors. In a series of papers, Diamond (1981; 1982a; 1982b; 1984) has studied this issue in depth. Diamond (1981) shows that in a market with a distribution of match specific mobility costs, an unemployment insurance programme can improve the ex ante welfare of all workers by inducing each of them to f...

The multiphoton states generated by high-gain spontaneous parametric down-conversion (SPDC) in presence of large losses are investigated theoretically and experimentally. The explicit form for the two-photon output state has been found to exhibit a Werner structure very resilient to losses for any value of the gain parameter, g. The theoretical results are found in agreement with the experiment...

1 Stein’s lemma • In a landmark paper, Stein (1981) derived a beautiful and simple lemma about the standard normal distribution. Indeed, Stein knew of this result much earlier and wrote about it in previous papers, but in Stein (1981), the author developed a multivariate extension of this lemma that led to a remarkable result on unbiased risk estimation. (And, an interesting note: the paper Ste...

By utilizing the frequency anticorrelation of two-photon states produced via spontaneous parametric down conversion (SPDC), the working principle of a novel remote spectrometer is demonstrated. With the help of a local scanning monochromator, the spectral transmission function of an optical element (or atmosphere) at remote locations can be characterized for wide range of wavelengths with expec...

Saccharides are polyhydroxy compounds, and their synthesis requires complex protecting group manipulations. Protecting groups are usually used to temporarily mask a functional group which may interfere with a certain reaction, but protecting groups in carbohydrate chemistry do more than protecting groups usually do. Particularly, protecting groups can participate in reactions directly or indire...

This paper aims to identify and analyze, as well formulate a settlement model for damage the conservation forest of Tanjung Panjang Nature Reserve in Pohuwato Regency. It uses statutory approach, conceptual case approach. An offer law enforcement against nature reserve Regency can be built using preventive, repressive persuasive A preventive approach will help prevent environment natural resour...

The growth of organic farming practices in the last few decades is continuing to stimulate the international debate about this alternative food market. As a p art of a PhD project r esearch about embeddedness in Alternative Food Networks (AFNs), this paper focuses on the promotional aspects of organic farms websites from the Madrid region. As a theoretical tool, some knowledge categories drawn ...

Natural systems harbor complex interactions that are fundamental parts of ecology and evolution. These interactions challenge our inclinations and training to seek the simplest explanations of patterns in nature. Not least is the likelihood that some complex processes might be missed when their patterns look similar to predictions for simpler mechanisms. Along these lines, theory and empirical ...

A study was carried out over a two year period (2009/2010 and 2012/2013) on an experimental farm in the Alentejo region (Beja), in southern Portugal where rainfed malt barley (Hordeum distichum L.) is sown at the end of autumn or beginning of winter (November–December). The aim of this experiment was to study the efficiency of the herbicide iodosulfuron-methyl-sodium to control post-emergence b...

Modeling of nature’s complexity is among the outstanding challenges we are faced with in the geophysical sciences. Although many ideas have been proposed throughout the years, the most common approaches, being based on notions related to chance, turn out to be insufficient to study, on an individual basis, the vast variety of patterns seen in nature. To this end, a novel deterministic fractal g...
