Abstract

We present the findings of a study based on a new inelastic electron-scattering experiment on the ${}^{12}\mathrm{C}$ nucleus focusing on the kinematic region of $Q^2=0.8\,\mathrm{GeV}^2/{c}^2$. The measured cross section is sensitive to the transverse response function and provides a stringent test of theoretical models, as well as of the theoretical assumptions made in Monte-Carlo event-generator codes developed for the interpretation of neutrino-nucleus experiments, such as DUNE and HyperK. We find that modern generators such as GENIE and GiBUU reproduce our new experimental data within 10$\%$.

Abstract

In this paper, we describe an experiment measuring low-$Q^2$ elastic electron-proton scattering using a newly developed cryogenic supersonic gas jet target in the A1 three-spectrometer facility at the Mainz Microtron. We measured the proton electric form factor within the four-momentum transfer range of $0.01\le Q^2 \le 0.045(\text{GeV/c})^2$. The experiment showed consistent results with the existing measurements. The data we collected demonstrated the feasibility of the gas jet target and the potential of future scattering experiments using high-resolution spectrometers with this gas jet target., Comment: 10 pages, 8 figures

Abstract

We report new p$(\vec{e},e^\prime p)\pi^\circ$ measurements in the $\Delta^{+}(1232)$ resonance at the low momentum transfer region utilizing the magnetic spectrometers of the A1 Collaboration at MAMI. The mesonic cloud dynamics are predicted to be dominant and appreciably changing in this region while the momentum transfer is sufficiently low to be able to test chiral effective calculations. The results disagree with predictions of constituent quark models and are in reasonable agreement with dynamical calculations with pion cloud effects, chiral effective field theory and lattice calculations. The reported measurements suggest that improvement is required to the theoretical calculations and provide valuable input that will allow their refinements.

Abstract

This paper reports on the first measurement of the ^16O(e,e'pn)^14N reaction. Data were measured in kinematics centred on a super-parallel geometry at energy and momentum transfers of 215 MeV and 316 MeV/c. The experimental resolution was sufficient to distinguish groups of states in the residual nucleus but not good enough to separate individual states. The data show a strong dependence on missing momentum and this dependence appears to be different for two groups of states in the residual nucleus. Theoretical calculations of the reaction using the Pavia code do not reproduce the shape or the magnitude of the data., Comment: 10 pages, 11 figures, 2 tables, Accepted for publication in EPJA

Abstract

We report new precise p$(\vec{e},e^\prime p)\pi^0$ measurements at the peak of the $\Delta^{+}(1232)$ resonance at $Q^2=\unit[0.20](GeV/c)^2$ performed at the Mainz Microtron (MAMI). The new data are sensitive to both the electric quadrupole ($E2$) and the coulomb quadrupole ($C2$) amplitudes of the $\gamma^* N\to\Delta$ transition. They yield precise quadrupole to dipole amplitude ratios CMR $= (-5.09 \pm 0.28_{stat+sys}\pm 0.30_{model})%$ and EMR $= (-1.96 \pm 0.68_{stat+sys} \pm 0.41_{model})%$ for $M^{3/2}_{1+} = (39.57 \pm 0.75_{stat+sys}\pm 0.40_{model})(10^{-3}/m_{\pi^+})$. The new results are in disagreement with Constituent Quark Model predictions and in qualitative agreement with models that account for mesonic contributions, including recent Lattice calculations. They thus give further credence to the conjecture of deformation in hadronic systems favoring the attribution of the origin of deformation to the dominance of mesonic effects., Comment: 2 figures

11. Executive Function and Children's Understanding of False Belief: How Specific Is the Relation?

Author

Muller, U., Zelazo, P.D, and Imrisek, S.

Abstract

The present study examined developmental relations among understanding false belief, understanding ''false'' photographs, performance on the Dimensional Change Card Sort (DCCS), and performance on a picture-sentence verification task in 69 3-5-year-old children. Results showed that performance on the DCCS predicted performance on false belief questions even after controlling for children's age and verbal ability. However, neither performance on the picture-sentence verification task, nor performance on the ''false'' photograph task predicted false belief understanding. Implications of these findings are discussed in the context of suggestions that understanding false belief reflects a general understanding of representation, propositional negation, and the ability to use higher order rules.

Abstract

The antiproton experiment PANDA at FAIR is designed to bring hadron physics to a new level in terms of scope, precision and accuracy. In this work, its unique capability for studies of hyperons is outlined. We discuss ground-state hyperons as diagnostic tools to study non-perturbative aspects of the strong interaction, and fundamental symmetries. New simulation studies have been carried out for two benchmark hyperon-antihyperon production channels: p¯ p→ Λ¯ Λ and p¯ p→ Ξ¯ +Ξ-. The results, presented in detail in this paper, show that hyperon-antihyperon pairs from these reactions can be exclusively reconstructed with high efficiency and very low background contamination. In addition, the polarisation and spin correlations have been studied, exploiting the weak, self-analysing decay of hyperons and antihyperons. Two independent approaches to the finite efficiency have been applied and evaluated: one standard multidimensional efficiency correction approach, and one efficiency independent approach. The applicability of the latter was thoroughly evaluated for all channels, beam momenta and observables. The standard method yields good results in all cases, and shows that spin observables can be studied with high precision and accuracy already in the first phase of data taking with PANDA.

Abstract

A new front-end electronics system has been developed for the electron arm tracking detectors in the KAOS spectrometer at the Mainz microtron MAMI. The signals of multi-anode photomultipliers are collected by 96-channel front-end boards, digitized by double-threshold discriminators and the signal time is picked up by F1 TDC chips. The system was designed to process more than 4,000 channels and to cope with the high electron flux in the spectrometer and the high count rate requirement of the detectors. A subset of 288 channels was installed and successfully used in the 2008 data taking period of the KAOS spectrometer.

Haustein (1) Keywords: Key wordsaAllergens; Peanut; Hazelnut; Digestion; Enzyme allergosorbent test; IgE immunoblotting Abstract: aStability under digestion is thought to be an important prerequisite determining the allergenicity of food proteins. To test this hypothesis, two important allergenic plant-derived foods were selected for this investigation. Protein extracts from roasted peanuts and unprocessed (native) hazelnuts were digested by a static, two-step in vitro procedure with commercial enzyme tablets containing peptic and pancreatic enzymes, respectively. The food extracts were subjected to gastric digestion for 2h followed by a 45-min treatment under duodenal conditions. Undigested control samples and the two digests were investigated by analytical sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), by SDS-PAGE immunoblotting, by an enzyme allergosorbent test (EAST) with human IgE, and by a rat basophil leukaemia (RBL) cell mediator release assay that depends on specific IgE raised in mice. Peanut proteins appeared to be more stable under digestion than hazelnut proteins, as shown by electrophoresis. These results were also underlined by immunblot data. The gastric digest from peanut contained various protein fragments that were detected by antibodies from a peanut-specific rabbit antiserum and by IgE from patients allergic to peanuts. These immunoblot reactivities decreased strongly after subsequent pancreatic digestion. In the gastric digest from hazelnuts, a rabbit antiserum with a broad reactivity against native hazelnut proteins exclusively recognized small protein fragments of &lt 15kDa. This serum showed no binding to blots of the pancreatic digest. Sera from hazelnut-allergic patients presented IgE reactivities to an 18-kDa major allergen with homology to major tree-pollen allergens, to a minor allergen of 12kDa, and to multiple bands a1a30kDa in native hazelnut extract. No binding was observed with these sera on blot strips of the two digests prepared from hazelnut extract. Under the native conditions of EAST, both digests from peanuts strongly reacted with human IgE. Their IgE binding capacity persisted at a level of about 50% when compared to undigested peanut. In the case of hazelnuts the IgE reactivity of the untreated samples was reduced to &lt 10% by both gastric and combined gastric/duodenal digestion for a serum pool prepared from four patients and sera from three additional participants. By contrast, a constantly high immunoreactivity of the hazelnut digests was detected with serum from one patient. The results of the EAST were confirmed by dose-related mediator release experiments performed with RBL cells passively sensitized with allergen-specific murine IgE. As a whole, our results indicated that the EAST and the RBL cell assay are superior to immunoblotting for the immunologic testing of digests. In accordance with clinical observations, the allergenicity of peanut proteins was very persistent during digestion, whereas the native birch-pollen-related hazelnut allergens appeared to be relatively labile under identical conditions.

Byline: U. Muller (1), W. Weber (2), A. Hoffmann (1), S. Franke (1), R. Lange (3), S. Vieths (1) Keywords: Key wordsaSoy lecithin; Residual allergens; Consumer protection Abstract: aSoybeans are known to be allergenic for adults as well as for infants. Processed products derived from soybeans are used in a wide spectrum of foods, drugs and other industrial products. In particular, soybean lecithins are used as stabilizers and emulsifiers and may not be suspected as possible source of allergens. To test this hypothesis, six commercial soy lecithins were investigated for residual allergenicity and compared with extracts from raw and heat-treated soybeans. They were characterized, the protein content was determined by enzyme-linked immunosorbent assay (ELISA) and allergens were analyzed with specific IgE from patients' sera using the enzyme allergosorbent test (EAST), EAST inhibition and protein blotting followed by immunodetection. For further characterization a polyclonal antiserum directed against soybean extract and a monoclonal antibody (mAb025) directed against the acidic subunit of the soybean storage protein glycinin were used. The EAST studies revealed that three of six sera from patients with allergy to soybeans contained IgE to four soy lecithins (Topcithin 50, Topcithin 300, Emulfluid FD 12, Epikuron 100 P), the same lecithins which were found to contain residual proteins. Two lecithins with a protein content of less than 20ppb did not bind IgE. EAST inhibition showed that the allergens from soy lecithin were immunologically more closely related to allergens from heat-treated soybeans than to those from raw soybeans. Protein blotting and immunodetection of the protein extract from the lecithins resulted in various allergen bands between 14kDa and 94kDa. A heat-stable allergen of 39kDa was recognized by the monoclonal antibody and thus identified as a subunit of glycinin. The results obtained were confirmed by a mediator release assay based on a rat basophil leukemia cell line. Lecithins that contained residual proteins caused a specific mediator release, suggesting that these products may induce allergic symptoms. Our results show that soybean lecithins are capable of introducing hidden allergens to processed foods and that the IgE binding potential corresponds to the total protein determined by ELISA. Furthermore, it appears to be possible that by monitoring the protein content soy lecithins can be applied which may be safe for the allergic consumer.

Abstract

This paper summarises a comprehensive Monte Carlo simulation study for precision resonance energy scan measurements. Apart from the proof of principle for natural width and line-shape measurements of very narrow resonances with PANDA, the achievable sensitivities are quantified for the concrete example of the charmonium-like $X(3872)$ state discussed to be exotic, and for a larger parameter space of various assumed signal cross-sections, input widths and luminosity combinations. PANDA is the only experiment that will be able to perform precision resonance energy scans of such narrow states with quantum numbers of spin and parities that differ from $J^{PC} = 1^{--}$., 19 pages, 14 figures, accepted for publication in EPJ-A

Abstract

Proteasomes degrade endogenous proteins. Two subunits, LMP-2 and LMP-7, are encoded in a region of the major histocompatibility complex (MHC) that is critical for class I-restricted antigen presentation. Mice with a targeted deletion of the gene encoding LMP-7 have reduced levels of MHC class I cell-surface expression and present the endogenous antigen HY inefficiently; addition of peptides to spienocytes deficient in LMP-7 restores wild-type class I expression levels. This demonstrates the involvement of LMP-7 in the MHC class I presentation pathway and suggests that LMP-7 functions as an integral part of the peptide supply machinery., MHC class I molecules present peptides derived from endogenously synthesized proteins to [CD8.sup.+] T cells. These peptides are thought to be generated in the cytosol and transported into the endoplasmic [...]

Abstract

Background Converging evidence suggests that immune-mediated dysfunction plays an important role in the pathogenesis of frontotemporal dementia (FTD). Although genetic studies have shown that immune-associated loci are associated with increased FTD risk, a systematic investigation of genetic overlap between immune-mediated diseases and the spectrum of FTD-related disorders has not been performed. Methods and findings Using large genome-wide association studies (GWASs) (total n = 192,886 cases and controls) and recently developed tools to quantify genetic overlap/pleiotropy, we systematically identified single nucleotide polymorphisms (SNPs) jointly associated with FTD-related disorders-namely, FTD, corticobasal degeneration (CBD), progressive supranuclear palsy (PSP), and amyotrophic lateral sclerosis (ALS)-and 1 or more immune-mediated diseases including Crohn disease, ulcerative colitis (UC), rheumatoid arthritis (RA), type 1 diabetes (T1D), celiac disease (CeD), and psoriasis. We found up to 270-fold genetic enrichment between FTD and RA, up to 160-fold genetic enrichment between FTD and UC, up to 180-fold genetic enrichment between FTD and T1D, and up to 175-fold genetic enrichment between FTD and CeD. In contrast, for CBD and PSP, only 1 of the 6 immune-mediated diseases produced genetic enrichment comparable to that seen for FTD, with up to 150-fold genetic enrichment between CBD and CeD and up to 180-fold enrichment between PSP and RA. Further, we found minimal enrichment between ALS and the immune-mediated diseases tested, with the highest levels of enrichment between ALS and RA (up to 20-fold). For FTD, at a conjunction false discovery rate < 0.05 and after excluding SNPs in linkage disequilibrium, we found that 8 of the 15 identified loci mapped to the human leukocyte antigen (HLA) region on Chromosome (Chr) 6. We also found novel candidate FTD susceptibility loci within LRRK2 (leucine rich repeat kinase 2), TBKBP1 (TBK1 binding protein 1), and PGBD5 (piggyBac transposable element derived 5). Functionally, we found that the expression of FTD +/- immune pleiotropic genes (particularly within the HLA region) is altered in postmortem brain tissue from patients with FTD and is enriched in microglia/macrophages compared to other central nervous system cell types. The main study limitation is that the results represent only clinically diagnosed individuals. Also, given the complex interconnectedness of the HLA region, we were not able to define the specific gene or genes on Chr 6 responsible for our pleiotropic signal. Conclusions We show immune-mediated genetic enrichment specifically in FTD, particularly within the HLA region. Our genetic results suggest that for a subset of patients, immune dysfunction may contribute to FTD risk. These findings have potential implications for clinical trials targeting immune dysfunction in patients with FTD.

Abstract

The helicity-dependent recoil proton polarizations P′x and P′z as well as the elicity-independent component Py have been measured in the p(→e,e′→p)π0 reaction at four-momentum transfer Q2≃0.1 GeV2, center-of-mass proton emission angle θ∗p≃90°, and invariant mass W≃1440 MeV. This first precise measurement of double-polarization observables in the energy domain of the Roper resonance P11(1440) by exploiting recoil polarimetry has allowed for the extraction of its scalar electroexcitation amplitude at an unprecedentedly low value of Q2, establishing a powerful instrument for probing the interplay of quark and meson degrees of freedom in the nucleon.

Abstract

The low-temperature method is described for the preparation of Si[O.sub.2] by thermal atomic layer deposition (ALD) and it has provided perfect uniformity and surface coverage even into nanoscale pores. Rapid thermal annealing (RTA) is shown to improve certain properties by reducing the etch rate in hydrofluoric acid, oxide charges and interface defects.

Abstract

An updated analysis using about 1.5 million events recorded at $\sqrt{s} = M_Z$ with the DELPHI detector in 1994 is presented. Eighteen infrared and collinear safe event shape observables are measured as a function of the polar angle of the thrust axis. The data are compared to theoretical calculations in ${\cal O} (\alpha_s^2)$ including the event orientation. A combined fit of $\alpha_s$ and of the renormalization scale $x_{\mu}$ in $\cal O(\alpha_s^2$) yields an excellent description of the high statistics data. The weighted average from 18 observables including quark mass effects and correlations is $\alpha_s(M_Z^2) = 0.1174 \pm 0.0026$. The final result, derived from the jet cone energy fraction, the observable with the smallest theoretical and experimental uncertainty, is $\alpha_s(M_Z^2) = 0.1180 \pm 0.0006 (exp.) \pm 0.0013 (hadr.) \pm 0.0008 (scale) \pm 0.0007 (mass)$. Further studies include an $\alpha_s$ determination using theoretical predictions in the next-to-leading log approximation (NLLA), matched NLLA and $\cal O(\alpha_s^2$) predictions as well as theoretically motivated optimized scale setting methods. The influence of higher order contributions was also investigated by using the method of Pad\'{e} approximants. Average $\alpha_s$ values derived from the different approaches are in good agreement., Comment: 48 pages
