We analyse the surface density of very faint galaxies at the limit of the sky background noise in the field of the cluster of galaxies Cl 0024+1654. The radial variation of their number density in the magnitude bins B = 26 − 28 and I = 24 − 26.5 displays an (anti)bias magnification effect similar to the one observed in A1689 by Broadhurst (1995) for I < 24. The study of this effect provides a d...

We report measurements on a Si-MOSFET sample with a slot in the upper gate, allowing for different electron densities n1,2 across the slot. The dynamic longitudinal resistance was measured by the standard lock-in technique, while maintaining a large DC current through the source-drain channel. We find that the conductance of the sample in a strong parallel magnetic field is asymmetric with resp...

A model for MOS capacitors in accumulation is presented, which is able to predict the nonlinear distortion accurately. The key idea of this work is to include the polysilicon gate depletion effect in that model. Several test structures based on MOS capacitors in accumulation have been implemented with the object of validating the model and to explore the potential applications to high performan...

This paper presents a polycrystalline silicon germanium (poly-SiGe) thermopile specially designed for thermoelectric generators used on human body. Both the design of the single thermocouple and the arrangement of the thermocouple array have been described. A rim structure has been introduced in order to increase the temperature difference across the thermocouple junctions. The modeling of the ...

In a model where enhanced economic activity (accumulation of produced capital) leads to environmental effects (depletion of natural capital), competitive steady states corresponding to different discount rates are compared. For positive discount rates, the steady state stock of produced capital may exceed the size maximizing sustainable consumption. This implies paradoxical consumption behavior...

A physical-based model for MOS capacitors in accumulation is presented, which is able to predict the non-linear distortion accurately. The key idea of this work is to include the polysilicon gate depletion effect in that model. Several test structures based on MOS capacitors in accumulation have been implemented with the aim of validating the model and to explore the potential applications to h...

Self-control relies on a limited resource that can get depleted, a phenomenon that has been labeled ego-depletion. We argue that individuals may differ in their sensitivity to depleting tasks, and that consequently some people deplete their self-control resource at a faster rate than others. In three studies, we assessed individual differences in depletion sensitivity, and demonstrate that depl...

to study the effect of sowing date and a single irrigation (si) on yield and yield components of barley, a field experiment was conducted in dryland agricultural research institute (maragheh, iran) in 2004-06 cropping seasons, using a split plot based on a randomized complete block design with 3 replications. main plots were assigned to 3 levels of sowing date (early, normal and late). sub-plot...

Background. The Limited Strength model [3] of cognitive psychology predicts that human capacity to exert cognitive effort is limited and that decision making is impeded once high depletion is reached. Aim. We investigate how password choice differs between depleted and undepleted users. Method. Two groups of 50 subjects each were asked to generate a password. One group was cognitively depleted,...
