Co-Zn ferrite and BaM ferrite films were deposited on silicon wafer disks with thermally oxidized surface layer without annealing process, and their readlwrite characteristics in contact mode have been investigated by using a MIG and Mn-Zn ferrite head with gap length of 0.2-0.4 pm. The highest linear recording density D50 of Co-Zn ferrite and Ba ferrite films were 105 and 190 WRPI, respectivel...

[1] A new data set of bimodal subaqueous channel bed sediments was analyzed for longitudinal patterns in grain size. It yielded two interesting observations: (1) separate fining trends in d50 exist for gravel and fines that overlap for 175 river kilometers, and (2) this overlap in fining trends results in a protracted (nonabrupt) gravel to sand transition. These suggest bed patchiness that is i...

We prove the non-emptiness of the core of an NTU game satisfying a condition of payoff-dependent balancedness, based on transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff vectors satisfying this condition. The additional requirement of transfer rate equilibrium refines the core concept and allows the selection of specif...

We state conditions for existence and uniqueness of equilibria in dynamic microeconomic models with an infinity of locally and globally interacting agents. Agents face repeated discrete choice problems. Their utility depends on the actions of some designated neighbors and the average choice throughout the whole population. We show that the dynamics on the level of aggregate behavior can be desc...

BACKGROUND/AIM The aims of this study were to evaluate the cell survival uncertainty distribution of radiation and to assess the accuracy of predictions of tumor response by using three different in vitro experimental cell cultures with radiosensitizers (including etanidazole). MATERIALS AND METHODS Using EMT6 cells and X-rays, the cell survival fraction was obtained from 15, 34, and 21 diffe...

Intraluminal manometric studies were performed in 14 chagasic patients with megaoesophagus, 10 chagasic patients with megacolon, and 15 control subjects. Basal lower oesophageal sphincter pressure was 20.27+/-1.16 mmHg (mean+/-SEM) in controls as compared wtih 15.16+/-1.53 mmHg in chagasics with megaoesophagus and 14.38+/-1.50 mmHg in chagasics with megacolon. Dose-response studies to intraveno...

The structure of rusticyanin is the largest unknown structure (M(r) = 16.8 kDa) which has been recently solved by the direct-methods approach using only single-wavelength anomalous scattering (SAS) data from the native protein [Harvey et al. (1998). Acta Cryst. D54, 629-635]. Here, the results of the Sim distribution approach [Hendrickson & Teeter (1981). Nature (London), 290, 107-113] and of t...

Current color-printing technologies may use three or more inks, e.g., CMY, CMYK, CMYKcm, CMYKGO, CMYKRGB. When the number of inks exceeds three, there is the usual color-management one-to-many mapping problem. Because the spectral properties of many modern inks are optimized for maximum color gamut and in some cases, black ink may not be used for pictorial images, many prints have poor color co...

We develop easy-to-verify conditions assuring that comparative statics in a general equilibrium model where time is a real line is feasible, i.e., the implicit function theorem is applicable. Consider an equilibrium equation, Υ(k,E) = k of a model where an equilibrium variable (k) is a continuous bounded function of time, real line, and the policy parameter (E) is a locally integrable function ...

We introduce the notion of type-symmetric randomized equilibrium (TSRE) by requiring those agents with the same type of characteristics to choose the same randomized choice. Such a notion provides a generic micro-foundation for the macro notion of equilibrium distribution, as used in the literature on games and economies with many agents. In particular, we show that if the space of agents is mo...
