The sheep genome contains 60 to 90 V lambda genes distributed in least 6 different families, whereas 37 V lambda genes and 10 families exist in humans. Comparison with human V lamda sequences indicates that sheep V lambda genes display less overall sequence divergence, but are closer to the genes most frequently used in the human peripheral repertoire. In both species, 2 to 3 genes contribute h...

In this paper, we present a novel Integer Linear Programming formulation (termed ILP4ID) for implicit search result diversification (SRD). The advantage is that the exact solution can be achieved, which enables us to investigate to what extent using the greedy strategy affects the performance of implicit SRD. Specifically, a series of experiments are conducted to empirically compare the state-o...

Decision support systems are generally geared to short-term tactical decision makkrg. As an alternative, this paper develops a mathematical progrming model to evaluate long-term strategic alternatives in the context of farm-level agricultural production where a broiler farm considers long-term implications of diversification into commercial aquiculture. The model considers a ten-year strategic ...

Recent developments in Information Retrieval diversity are based on the consideration of a space of information need aspects, a notion which takes different forms in the literature. The choice of a suitable aspect space for diversification is a critical issue when designing an IR diversification strategy, which has not been explicitly addressed to some depth in the literature. This paper aims t...

Portfolio diversification and active risk management are essential parts of financial analysis which became even more crucial (and questioned) during and after the years of the Global Financial Crisis. We propose a novel approach to portfolio diversification using the information of searched items on Google Trends. The diversification is based on an idea that popularity of a stock measured by s...

A common organizational feature of nervous systems is the existence of groups of neurons that share common traits but can be divided into individual subtypes based on anatomical or molecular features. We elucidate the mechanistic basis of neuronal diversification processes in the context of C.elegans ventral cord motor neurons that share common traits that are directly activated by the terminal...

Reducing corporate risk has long been a business strategy concern. Many scholars support diversification as a method to achieve risk reduction. Building on organisational portfolio analysis, we develop the concept of ‘desynchronicity’ as a complement to existing diversification theories about risk reduction. Organisational portfolio analysis views firms as portfolios of business units, suggesti...

We develop a new theory of supplier diversification based on buyer risk. When suppliers are subject to the risk of buyer default, buyers may take costly action to signal creditworthiness so as to obtain more favorable terms. But once signaling costs are sunk, buyers sourcing from a single supplier become vulnerable to future holdup. Although ex ante supply base diversification can be effective ...

the credit portfolio management and the optimal credit portfolio selection are identified as one of the most effective factors in banks’ credit risk. two main strategies in this regard include diversification versus concentration. in this study, at first, the status of diversification of iran’s banking sector is analyzed, then the relationship between diversification of the credit portfolio and...
