In [C. Duval, V. Ovsienko, Projectively equivariant quantization and symbol calculus: Noncommutative hypergeometric functions, Lett. Math. Phys. 57 (1) (2001) 61–67], the authors showed the existence and the uniqueness of a sl(m+1,R)-equivariant quantization in non-critical situations. The curved generalization of the sl(m+1,R)-equivariant quantization is the natural and projectively equivariant quantization. In [M. Bordemann, Sur l’existence d’une prescription d’ordre naturelle projectivement invariante (submitted for publication). math.DG/0208171] and [Pierre Mathonet, Fabian Radoux, Natural and projectively equivariant quantizations by means of Cartan connections, Lett. Math. Phys. 72 (3) (2005) 183–196], the existence of such a quantization was proved in two different ways. In this paper, we show that this quantization is not unique. [less ▲]

We report on the cDNA cloning and characterization of a novel short-chain isoprenyl diphosphate synthase from the aphid Myzus persicae. Of the three IPPS cDNAs we cloned, two yielded prenyltransferase activity following expression in Escherichia coli; these cDNAs encode identical proteins except for the presence, in one of them, of an N-terminal mitochondrial targeting peptide. Although the aphid enzyme was predicted to be a farnesyl diphosphate synthase by BLASTP analysis, rMpIPPS, when isopentenyl diphosphate and dimethylallyl diphosphate are supplied as substrates, typically generated geranyl diphosphate (C10) as its main product, along with significant quantities of farnesyl diphosphate (C15). Analysis of an MpIPPS homology model pointed to substitutions that could confer GPP/FPP synthase activity to the aphid enzyme. [less ▲]

Pour autant, l’homme ordinaire d’aujourd’hui n’est-il vraiment qu’une marionnette comme le prétend toute une partie de la critique de gauche ?

Toll-like receptors (TLRs) as well as the receptors for tumor necrosis factor (TNF-R) and interleukin-1 (IL-1R) play an important role in innate immunity by regulating the activity of distinct transcription factors such as nuclear factor-kappaB (NF-kappaB). TLR, IL-1R and TNF-R signaling to NF-kappaB converge on a common IkappaB kinase complex that phosphorylates the NF-kappaB inhibitory protein IkappaBalpha. However, upstream signaling components are in large part receptor-specific. Nevertheless, the principles of signaling are similar, involving the recruitment of specific adaptor proteins and the activation of kinase cascades in which protein-protein interactions are controlled by poly-ubiquitination. In this review, we will discuss our current knowledge of NF-kappaB signaling in response to TLR-4, TNF-R and IL-1R stimulation, with a special focus on the similarities and dissimilarities among these pathways.

This contribution aims to show a multidisciplinary method to understand and formalize design process, from a cognitive point of view, in the particular case of human errors in architectural preliminary design process. We first emphasize the importance of error detection and recovery in the sketching phase in architecture. After the description of our methodology, we explain the general theory and model on human error, the short study we made and our proposition of a model on hu- man error in architectural design. We finally conclude by giving some first re- quirements from this model in order to improve to the development of sketch- based CAD tools. [less ▲]

Using standard group theoretical techniques we construct the exact wave function of the $[{\bf 70},1^-]$ multiplet in the orbital, spin and flavor space. This symmetric wave function is compared to that customarily used in the $1/N_c$ expansion, which is asymmetric. The comparison is made by analyzing the matrix elements of various operators entering the mass formula. These matrix elements are calculated by the help of isoscalar factors of the permutation group, specially derived for this purpose as a function of $N_c$. We also compare two distinct methods used in the study of the $[{\bf 70},1^-]$ multiplet. In the first method the generators are divided into two parts, one part acting on a subsystem of $N_c-1$ quarks called core and another on the separated quark. In the second method the system is treated as a whole. We show that the latter is simpler and allows to clearly reveal the physically important operators in the mass formula. [less ▲]

Analysis of passive microwave brightness temperatures from the space-borne Special Sensor Microwave Imager (SSM/I) documents a record surface snowmelt over high elevations (above 2000 m) of the Greenland ice sheet during summer of 2007. To interpret this record, results from the SSM/I are examined in conjunction with fields from the National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis and output from a regional climate model. The record surface melt reflects unusually warm conditions, seen in positive summertime anomalies of surface air temperatures, downwelling longwave radiation, 1000–500 hPa atmospheric thickness, and the net surface energy flux, linked in turn to southerly airflow over the ice sheet. Low snow accumulation may have contributed to the record through promoting anomalously low surface albedo. [less ▲]

Seed dispersal has a profound influence on structure and diversity in tropical environment. Although all frugivorous primates disperse seeds, the contribution of dispersal by some species in forest regeneration is still discussed. For instance, baboons and macaques are controversially described as seed dispersers or as seed predators. We study the seed dispersal by a troop of pigtail macaques (Macaca nemestrina leonina) in the Khao Yai National Park (Thailand) in order to describe the mode of seed dispersal and the seed fate of each fruit species consumed by macaques, including the assessment of potential germination enhancement for dispersed seeds. Pigtail macaques disperse seeds either via feces, by swallowing seeds, or via cheekpouch storage, by spitting out seeds after processing the fruits in the mouth. Preliminary results of our study show that pigtail macaques in the study troop disperse the seeds of at least 15 fruits species. For some species (Nephelium melliferum, Baccaurea ramiflora), macaques use the 2 modes of seed dispersal simultaneously. If part of the seeds excreted are intact and viable, as shown by the cut test, some are destroyed during mastication and digestion, and therefore it seems that macaques are to be considered both as seed dispersers and predators. The size of dispersed seeds ranges from the largest defecated seed (Nephelium melliferum) of 22mm long and 13mm wide to the smallest (Dissocheta divaricata) less than 1mm long and 0.5mm wide. In the future, Tetrazolium test will also be used to assess seed viability, and the germination enhancement for seeds defecated or spat out will be assessed using germination test. Germination rate and germination delay will be compared for defecated, spat and control (seeds from non consumed fruits collected from trees foraged by the macaques) seeds. [less ▲]

VP22, encoded by theUL49gene of Marek’s disease virus (MDV), is indispensable for virus cell-to-cell spreading. We show herein that MDVUL49can be functionally replaced with avian and human viral orthologs. Replacement of MDV VP22 with that of avian gallid herpesvirus 3 or herpesvirus of turkey, whose residue identity with MDV is close to 60%, resulted in 73 and 131% changes in viral spreading, respectively. In contrast, VP22 replacement with human herpes simplex virus type 1 resulted in 14% plaque formation. Therefore, heterologous avian and human VP22 proteins share sufficient structural homology to support MDV cell-to-cell spreading, albeit with different efficiencies. [less ▲]
