This paper seeks to uncover an inconvenient truth. The Microsoft decisions are not tying cases. Rather, the two decisions taken by the EU Commission against Microsoft – i.e. the Windows Media Player (“WMP”) case of 2004 and the Internet Explorer (“IE”) case of 2009 – mark departures from conventional tying analysis (I). First, they deviate from standard tying law in that in the Microsoft cases, a key component of abusive tying, namely coercion, is missing (II). Second, the Microsoft decisions share many analogies with “essential facility” cases. One may thus question to what extent the Commission has not pursued disguised refusal to supply cases (III).

Lysozyme from lambda bacteriophage (lambda lysozyme) is an 18 kDa globular protein displaying some of the structural features common to all lysozymes; in particular, lambda lysozyme consists of two structural domains connected by a helix, and has its catalytic residues located at the interface between these two domains. An interesting feature of lambda lysozyme, when compared to the well-characterised hen egg-white lysozyme, is its lack of disulfide bridges; this makes lambda lysozyme an interesting system for studies of protein folding. A comparison of the folding properties of lambda lysozyme and hen lysozyme will provide important insights into the role that disulfide bonds play in the refolding pathway of the latter protein. Here we report the (1)H, (13)C and (15)N backbone resonance assignments for lambda lysozyme by heteronuclear multidimensional NMR spectroscopy. These assignments provide the starting point for detailed investigation of the refolding pathway using pulse-labelling hydrogen/deuterium exchange experiments monitored by NMR. [less ▲]

This contribution summarizes considerations developed to allow a reasonable and consistent definition of the national parameters to be introduced in the Belgian national annex to chapter 9 of Eurocode 8 dealing with seismic design of masonry structures. The different aspects considered are material properties (resistance and ductility), detailing of wall-wall and wall-floor connections and rules for simple masonry buildings. The result is a set of rules consistent with the national practice and defining (i) what is allowed in Belgium for the different seismic zones, (ii) minimal requirements for simple non-engineered buildings and (iii) a procedure that can be followed to improve these rules for materials and structural systems exhibiting better properties than the minimal requirements of Eurocode 8.

Male osteoporosis represents an important, although long underestimated, public health problem. Both in men and in women aging is accompanied by continuous bone loss and by an exponential increase in the incidence of osteoporotic fracture, with a female to male incidence ratio of about 2 to 3 to 1 in the elderly for hip and vertebral fractures. Morbidity after osteoporotic fractures appears to be more serious and mortality more common in men than in women. To date, no single treatment has been proved to be effective and safe in published prospective studies. The present report, based on a systematic search of the literature on male osteoporosis, summarises the state of the art on the clinical consequences of male osteoporosis and its risk factors, in relation to the present state of knowledge about female osteoporosis. This constitutes the background for the design of rational clinical development strategies for therapeutic interventions in male osteoporosis. From this review of the literature it is apparent that notwithstanding the existing sex differences in pathophysiology of osteoporosis and the difference in age-specific incidence of osteoporotic fractures, there are also important similarities between osteoporosis in women and men. The higher incidence of fracture in women than in men results from quantitative differences in risk factors rather than from different risk factors. Even though there are sex differences in bone geometry, incidence of fracture seems to be similar in men and women for a same absolute areal bone mineral density. However, the lack of data on the changes in fracture rates in men resulting from pharmacological intervention, leading to changes in bone mineral density or bone turnover, remains the main limitation for extrapolation of established treatment outcomes from women to men.

Motion detection plays an important role in most video based applications. One of the many possible ways to detect motion consists in background subtraction. This paper discusses experiments led for a particular background subtraction technique called ViBe. This technique models the background with a set of samples for each pixel and compares new frames, pixel by pixel, to determine if a pixel belongs to the background or to the foreground. In its original version, the scope of ViBe is limited to background modeling. In this paper, we introduce a series of modifications that alter the working of ViBe, like the inhibition of propagation around internal borders or the distinction between the updating and segmentation masks, or process the output, for example by some operations on the connected components. Experimental results obtained for video sequences provided on the workshop site validate the improvements of the proposed modifications. [less ▲]

We consider a three dimensional (3D) finite element modeling of high temperature superconductors (HTS) submitted to a uniform magnetic field varying linearly with time. HTS are characterized by a non linear conductivity described by a power law with the critical exponent, n. We implement an A- phi weak formulation into the opensource solver GetDP. Backward Euler method is used for the temporal resolution and is coupled to a non linear Picard iteration scheme for dealing with the non linear resistivity of HTS.We consider single- and multiple-time step methods and show that the single time step method produces an accurate result in a drastically reduced calculation time for HTS with large pinning strength (or similarly, with large values of n). The finite element formulation is validated by comparing the magnetization of a HTS tube calculated either with our finite element formulation or with other well-known techniques. The numerical method is then applied for comparing the magnetization of cylinders that are drilled by different periodic arrangements of columnar holes parallel to the cylinder axis. [less ▲]

Backyard poultry is considered as a powerful tool for poverty alleviation. It is further promoted as a way of empowering women in communities where there is gender bias in poultry raising. The low-input systems involved are based on local breeds that are perfectly suited to their environment. However, socio-economic processes put local genetic resources under pressure, leading to the erosion of biodiversity. The present survey addresses this issue in the case of Kabylie, a mountainous coastal region of Algeria, through a survey conducted in 90 households raising poultry, a morpho-biometric description of 315 local chickens, and a performance evaluation of both growth and egg production in experimental semi-intensive conditions. The socio-economic profile of poultry smallholders in Kabylie reveals poor education and high diversification of agricultural assets and confirms gender bias in poultry keeping. The erosion of local genetic resources in chicken is found to be severe despite their cultural importance in Kabylie. From complementary surveys among experienced poultry keepers, the major original local type is postulated to consist of three varieties with black plumage (pure black, mottled and barred). The performance evaluation raised promising results, suggesting that some degree of improvement of low-input backyard systems could be pursued by exploiting the local breed. Finally, a strategy for a revival of the local breed through the support of the most involved smallholders is outlined in accordance with the information collected in the survey. [less ▲]

We studied 622 transplants undertaken between 1982 and 2001 to: (1) determine the incidence, timing and etiology of bacteremias, and (2) examine the ability of routine surveillance cultures to predict bacteremias. A total of 404 episodes (0.65 episode per patient) occurred in 248 patients, due to coagulase-negative staphylococci (n=171, 42%), Gram-negative bacteria (n=129, 32%), streptococci (n=48, 12%), other Gram-positive bacteria (n=33, 8%), anaerobes (n=9, 2%) and fungi (n=14, 3%). Bacteremias were more frequent in allogeneic (0.96 episode/patient) compared to autologous (0.44) transplants (P<0.0001). The overall incidence decreased from 0.92 episode/patient until 1990 to 0.66 in 1991-1996 and 0.55 in 1997-2001 (P<0.0001), but this was only observed in autologous transplants. Among them, 212 (53%) occurred before hospital discharge and 192 (47%) thereafter. This proportion was lower for coagulase-negative staphylococci, other Gram-positive bacteria and Gram-negative bacteria compared to other agents (P=0.001). In 50% of the cases, the agent responsible for the bacteremic episode was present in routine surveillance cultures previously. In conclusion: (1) bacteremias remain a frequent complication, particularly in allogeneic transplantation, even long after hospital discharge; (2) routine surveillance cultures can predict bacteremias in 50% of the cases, but the practical impact of this observation is limited in view of the costs.

For several years, similar karsts to those found in the limestone have been observed in various silicated non-carbonated rocks. Several morphological arguments show that a complete dissolution of rocks is necessary to explain the formation of some caves and other related forms independently of hydrotermalisme phenomena. However, the physico-chemical processes generally considered do not provide a satisfactory explanation to this dissolution. Bacterial activity found deep in many lithologies provides a solution to this apparent contradiction. [less ▲]

The bacterial active-site serine penicillin-hydrolyzing and penicillin-binding proteins or domains operate by a serine-ester-linked acyl enzyme mechanism similar to that of the peptidases of the trypsin and subtilisin families. On the basis of known primary and tertiary structures, predictive studies support the view that these proteins or domains form a superfamily of evolutionarily related enzymes. Although--depending on the evolutionary distance--they may have very different amino acid sequences and distinct functional characteristics and specificities, they all would have conserved the same unprecedented type of polypeptide scaffolding. When obtained, complete structural information should provide the necessary tools for the rational design of novel types of inactivators of these important enzyme targets. [less ▲]
