Front-form calculation of the deuteron EM form factors

The deuteron form factors are calculated in the framework of the relativistic nucleon-meson dynamics. The relativistic effects change considerably the S- and D-waves of the deuteron, result in the dominating extra component in the deuteron wave function and generate the contact interaction between the nucleon, mesons and photon. The prediction for the polarization observable $t_{20}$ is in good agreement with the recent data of TJNAF/CEBAF.Comment: 4 pages, 1 figure.

What memory binding functions is the hippocampus responsible for?

The role of the hippocampus in binding information in working memory (WM) is little understood. When complex experiences comprise associations between different pieces of information such as objects and locations (relational binding), the function of the hippocampus is required to hold them in WM (Mitchell et al., 2000; 2006; Piekema, 2006). However, recent evidence suggests that if the to-be-associated information leads to the formation of integrated objects such as coloured shapes (conjunctive binding), the hippocampus is less involved in holding temporary representations of these complex events in WM (Baddeley et al., 2010; Piekema, 2006). We investigated the relational and conjunctive binding hypotheses of the hippocampal functions in a patient with right hippocampal damage. The patient and controls were asked to study visual arrays of stimuli which consisted of shape-colour relations (shape-colour pairs) or shape-colour conjunctions (coloured shapes). After the study array, they were presented with a new screen consisting of one set of shapes (line drawings) and one set of colours. They were asked to reconstruct the bindings by selecting the shapes and their corresponding colours. As compared to healthy controls, the patient was impaired in holding relations of shapes and colours in WM whereas he could retain the conjunctions similarly to controls. These results lend support to the role of the hippocampus in supporting memory for inter-item associations but not memory for conjunctions of features which define objects' identity

Genetic stability of Campylobacter coli in patients with primary antibody deficiencies

In the Clinical Communication, Dion et al 1 reported that in patients with severe primary antibody deficiency (PAD), Campylobacter infection is a major cause (6.5%) of chronic or recurrent diarrhea. Moreover, by a molecular study performed in a subset of 18 strains from 5 patients with recurrent infections, they demonstrated that all strains were different, even when the episodes occurred closely over time. Thus, the authors hypothesized that reinfection would be more likely than persistent colonization, although colonization with multiple strains cannot be excluded. In a previous study, 2 our group showed that Campylobacter coli (C. coli) (6.7%) was the first cause of diarrhea in patients with symptomatic PAD with a positive stool culture, followed by Campylobacter jejuni (C. jejuni) (3.9%). Moreover, C. coli was also the most frequent isolate (5%) in patients with asymptomatic PAD, followed by C. jejuni (1.2%), whereas in immunocompetent individuals, C. jejuni is one of the most prevalent etiologic agents of gastroenteritis and C. coli has a low prevalence in diarrheal disease

Single Wall Carbon Nanotubes Filled with Metallocenes: a First Example of Non-Fullerene Peapods

We report the synthesis and analysis of metallocenes (ferrocene, chromocene, ruthenocene, vanadocene, tungstenocene-dihydride) encapsulated in single wall carbon nanotubes (SWNTs). In the case of ferrocene, efficient filling of the SWNTs was accomplished from both the liquid and the vapor phase. The other two metallocenes were filled from the vapor phase. High resolution transmission electron microscopy reveals single molecular chains of metallocenes inside SWNTs. Molecules move under the electron beam in the SWNTs indicating the absence of strong chemical bonds between each other and the SWNT wall. Their movement freezes after short illumination as a result of irradiation damage. Energy dispersive X-ray spectrometry confirms the presence of iron, chromium, ruthenium, vanadium and tungsten
