A yield enhanced layout method for maximizing yield of integrated resistor networks with a fixed total area is discussed. This approach incorporates both random variations in the sheet resistance and random variations in the contact resistances. The concept of contact/sheet resistance crossover which gives the crossover between contact-resistance dominance and sheet resistance dominance is deve...

Micro-pattern gas detectors, such as the Gas Electron Multiplier (GEM) and the Micromegas need narrow high density anode readout elements to achieve good spatial resolution. A high-density anode readout would require an unmanageable number of electronics channels for certain potential micro-detector applications such as the Time Projection Chamber. We describe below a new technique to achieve g...

We have investigated Mn, Co and Ni substitution effects on polycrystalline samples of LaFePO0.95F0.05 by resistivity and magnetoresistance measurements. In LaFe1-xMxPO0.95F0.05 (M = Mn, Co and Ni), the superconducting transition temperature (Tc) monotonously decreases with increasing the impurity doping level of x. There is a clear difference of Tc suppression rates among Mn, Co and Ni doping c...

this study is considering a micropolar fluid flow over a porous stretching sheet in the presence of thermal radiation and uniform magnetic field. the effects of local variation in thermal conductivity of micropolar fluid on heat transfer rate from the sheet are investigated; besides, the impacts of radiation, magnetic field and porous sheet on variations of thermal boundary layer thickness are ...

A study was carried out to understand the mineral constituent variations under cobalt treatment in Vigna mungo (L.) Hepper. The experiments were conducted in earthen pots and lined the inner surface with polythene sheet. Each pot contains 3 kg of air dried soil. Blackgram plants were raised in these pots containing soils amended with different concentrations of cobalt (0, 50, 100, 150, 200 and ...

because of production process and constrains conditions, circular graphene sheet may be opposed to structural defect and pin hole, respectively. some of the defects and pin hole on a circular graphene sheet can be considered as an eccentric hole on the sheet. hence, analyzing behavior of circular graphene sheet with an eccentric hole is important. free vibration of an eccentric annular graphene...

Enzymes used for passaging human pluripotent stem cells (hPSCs) digest cell surface proteins, resulting in cell damage. Moreover, cell dissociation using divalent cation-free solutions causes apoptosis. Here we report that Mg(2+) and Ca(2+) control cell-fibronectin and cell-cell binding of hPSCs, respectively, under feeder- and serum-free culture conditions without enzyme. The hPSCs were detach...

balance sheet itself does not specify and show all the activities that a bank pays. because banks can do many swap contracts and obligations, exchange, and commitments outside of the balance sheet. to such activities and exchange that will not appear on the balance sheet, are saying off-balance sheet activities. these items are usually reported in the notes to the attached financial statements....

A series of nitrogen-doped carbons (NCs) were prepared by the pyrolysis (300–900 °C) crystalline polyazomethine (PAM) synthesized via a facile condensation reaction in methanol solvent. The controlled solvent evaporation resulted PAM crystals form nanosheet clusters with sheet thickness ~50 nm. Such architecture was maintained after pyrolysis, obtaining porous CNs high specific surface areas up...
