Using a sample of firms with ultimate ownership data from 9 East Asian and 13 Western European countries, this study investigates whether the wedge between voting rights (control) and cash flow rights (ownership) influences a firm’s information environment, in particular, the extent to which firm-specific information is incorporated into stock prices which we conveniently call stock price infor...

to investigate flowering, fruitlet and fruit set in thomson navel orange and satsuma mandarin cv. miyagawa and sugiyama in climatic conditions of eastern mazandaran, an experiment was performed by combined analysis in randomized complete block design in three different orchards and in three consecutive years with five replications. number of flowers, fruitlets and fruits were recorded and later...

Background and Objectives: One of the key issues in determining location for blood supply center is the design of blood supply chain. To minimize the cost of blood supply, the donors should be reached easily with appropriate distribution of blood and blood products to the hospital. The aim of this study was calculating of the optimal number and location of different various t...

East African elephants have been hunted for their ivory for millennia but the nineteenth century witnessed strongly escalating demand from Europe and North America. It has been suggested that one consequence was that by the 1880s elephant herds along the coast had become scarce, and to meet demand, trade caravans trekked farther into interior regions of East Africa, extending the extraction fro...

An efficient two-step protocol for the asymmetric synthesis of 1H-pyrrol-3(2H)-one derivatives in 99% ee from conveniently accessed 2,3-diketoesters has been developed.

In this paper we provide a systematic way to construct the robust counterpart of a nonlinear uncertain inequality that is concave in the uncertain parameters. We use convex analysis (support functions, conjugate functions, Fenchel duality) and conic duality in order to convert the robust counterpart into an explicit and computationally tractable set of constraints. It turns out that to do so on...

In this paper, we propose a novel approach for designing planar dual-band bandpass filter on a novel feed scheme. While we design this filter, the novel feed scheme is used to generate two passbands at 1.8 GHz and 2.4 GHz for global system for mobile communications (GSM) and wireless local area network (WLAN). Novel feeding structures are introduced to simultaneously feed the resonators and con...

A periodic graph in dimension d is a directed graph with a free action of Z with only finitely many orbits. It can conveniently be represented in terms of an associated finite graph with weights in Z. Here we use the weight sums along cycles in this associated graph to construct a certain polytope in R, which we regard as a geometrical invariant associated to the periodic graph. It is the unit ...

Many AI problems can be conveniently encoded as discrete constraint satisfaction problems. It is often the case that not all solutions to a CSP are equally desirable | in general, one is interested in a set of \preferred" solutions (for example, solutions that minimize some cost function). Preferences can be encoded by incorporating \soft" constraints in the problem instance. We show how both h...
