Imagine n children playing together. The mother of these children has told them that if they get dirty there will be severe consequences. So, of course, each child wants to keep clean, but each would love to see the others get dirty. Now it happens during their play that some of the children, say k of them, get mud on their foreheads. Each can see the mud on others but not on his own forehead. ...

This paper investigates optimum and sub-optimum linear Minimum Mean Square Error (MMSE) Multi-User Detection (MUD) techniques for multi-carrier code division multiple access transmission systems. In a first step, we present two formulations of MMSE MUD techniques that are optimum for any number of users and any power distribution and achieve exactly the same performance with a different computa...

In present investigation the biological leaching of aluminum by isolated fungi from red mud, the main waste product of the alkaline extraction of Al from bauxite was studied. Biological leaching experiments were carried out using indigenous, date and orange specimen fungi, Aspergillus Niger, Penicillium simplicissimum notatum. Savored Dextrose chloramphenicol Agar (SDA) wa...

BACKGROUND The role of reduced-intensity conditioning allogeneic stem cell transplantation in relapsed/refractory Hodgkin's lymphoma remains poorly defined. We here present an update of our single-center experience with fludarabine-melphalan as a preparative regimen. DESIGN AND METHODS Fifty-eight patients with relapsed/refractory Hodgkin's lymphoma underwent RIC and allogeneic stem cell tran...

Although multiple predator effects and trophic cascades have both been demonstrated in a wide variety of ecosystems, ecologists have yet to incorporate these studies into an experimental framework that also manipulates a common and likely important factor, spatial heterogeneity. We manipulated habitat complexity, the presence of two top predators (toadfish and blue crabs), and one intermediate ...

In a companion paper [4], space-time layered architectures (BLAST) and turbo coding/processing techniques, which are effective for single-link transmission, are combined with multiuser detection (MUD) methods for combating intercell interference. It is shown that, depending on the channel configuration, linear MMSE or successive interference cancellation (SIC) can be the preferable MUD method. ...

The pore pressures of the S, R, Q and P sands follow the hydrostatic gradient and are in pressure communication across the entire Auger basin, Gulf of Mexico. At the structural crests of these sands the pore pressures exceed the least principle stress; directly above the sand crests, are a series of mud volcanoes. Using 3-D seismic and pressure data we map the distribution of subsurface pressur...

––The oily mud waste is one of the main wastes in oil field production process, which also stands as a critical negative factor that impedes the improvement of oilfield environment. The oily mud, which is rich in oil and black viscous compound in appearance, is the solid waste that comes along with the oilfield production. The oily mud mixture has huge amounts in magnitude, and it contains a ce...

Biological leaching experiments were carried out using indigenous, date and orange specimen fungi, Aspergillus Niger, Penicillium simplicissimum notatum.

Mud volcanoes can be large and long lived geological structures that morphologically resemble magmatic volcanoes. Because of their capricious behaviour and their spectacular morphology and landscapes, mud volcanoes have attracted attention since antiquity. More recently, mud volcanoes have become the focus of extensive studies for natural science research, including geologists and biologists. M...
