We performed ac susceptibility measurements to explore the vortex dynamics and the flux-pinning properties of superconducting Pb films with an array of microholes (antidots) and not fully perforated holes (blind holes). A lower ac shielding together with a smaller extension of the linear regime for the lattice of blind holes indicates that these centers provide a weaker pinning potential than antidots. Moreover, we found that the maximum number of flux quanta trapped by a pinning site, i.e., the saturation number n(s), is lower for the blind hole array. [less ▲]

In Europe, most of the urban public transport services are not operated on a commercial basis. The implication of local public authorities in the sector is important: they organize their local market, they finance services and, sometimes, they also act as producers. This paper analyzes the public transport system in four European cities: Lyon, Stockholm, Helsinki and Brussels and concentrates, in particular, on the introduction of regulated competition. Four different market mechanisms can be used in the public transport sector: (1) competitive tendering, (2) open access with on-track competition, (3) yardstick competition where the operator’s reward is based on a comparative evaluation of its performance and (4) the possibility of challenging the incumbent public operator. The pros and cons of different competitive mechanisms are presented and the article discusses the conditions under which a truly competitive market could be settled [less ▲]

The oncoprotein HER-2/neu is a prosurvival factor, and its overexpression has been correlated with poor prognosis in patients with breast cancer. We report that HER-2 is a new substrate for caspase-8 and that tumor necrosis factor alpha (TNF-alpha) stimulation leads to an early caspase-8-dependent HER-2 cleavage in MCF7 A/Z breast adenocarcinoma cells defective for nuclear factor kappaB (NFkappaB) activation. We show that the antiapoptotic transcription factor NFkappaB counteracts this cleavage through induction of the caspase-8 inhibitor c-FLIP. Our results also demonstrate that this HER-2 cleavage contributes to the TNF-alpha-induced apoptosis pathway because ectopic expression of an uncleavable HER-2 protects NFkappaB-defective cells against TNF-alpha-mediated cell death. Therefore, we propose an original model in which NFkappaB exerts a new antiapoptotic function by counteracting TNF-alpha-triggered cleavage of the HER-2 survival factor. [less ▲]

This article studies a simple procurement problem (Laffont and Tirole, 1993) where the regulator faces a cash-in-advance constraint. The introduction of such a constraint not only reduces the amount of public good provided but also limits the instruments available to the regulator. The wealth constraint could change the optimal regulatory contract from a two-part tariff, where the quantities produced depend on the firm's cost, to a less efficient fixed fee where the firm produces the same quantity whatever its cost.

The 4M-µpump project attempts to breach the gap between traditional mechanics and micro mechanics and this in two ways. The first one consists in producing a general set of rules suitable for the miniaturisation of well-known macromachines. The second one consists in developing this fundamental aspect of the research through the design and realization of an implantable pump dedicated to the administration of medication agents inside the human body. The project thus touches upon the field of design, manufacturing, metrology and assembly of mini components as well as the study of minimotors. [less ▲]

The final draft of the EN version of part 1.1 of Eurocode 3 has introduced significant changes in the evaluation of the lateral-torsional buckling resistance of unrestrained beams at room temperature that reduce the over-conservative approach of ENV 1993-1-1 in the case of non-uniform bending. Numerical modelling of the lateral-torsional buckling of steel beams at elevated temperature has shown that the beam design curve from prEN 1993-1-2 is over-conservative for loadings other than uniform bending. In line with the safety format of the lateral-torsional buckling code provisions for cold design, an alternative proposal for rolled sections or equivalent welded sections subjected to fire is presented in this paper, that addresses the issue of the influence of the loading type on the resistance of the beam, achieving better agreement with the real behaviour while maintaining safety.

The simplification of recording procedures constitutes an economic alternative to reduce operational costs when national recording programs are concerned in low input production systems. A total of 54 940 daily milk yields from a herd of 63 Holstein cows recorded in 3 years were used in this study. The effect of reducing tests to measure the accuracy of 305 milk yields was investigated. Two methods of total milk yield computation (the Test Interval Method (TIM) and the Interpolation using Standard Lactation Curves (ISLC)) were compared based on 495 combinations of milk recording alternatives. These alternatives were based on 2 milkings/day, one alternated milking (AM/PM) and one non-alternated milking (AM or PM). All of them were used with 9 intervals between consecutive tests (3 to 11 weeks) and 11 intervals between calving date and the first test day. Results showed that the differences between the actual 305 d milk yield and milk estimated by TIM were the smallest on consecutive test days of maximum 6 weeks of intervals. Differences increased in both sides positively back to A3 and negatively toward A11. Standard estimation errors increased from 4 to 9 from A3 to A11. Phenotypic correlations decreased from .99 to .94 when intervals between the calving date and the first test day increased and this for all test methods (A3-A 11). The ISLC led to a better accuracy of milk yield estimation when intervals between consecutive tests got longer. [less ▲]
