[en] The first ⁶⁰Co-contaminated rebar building was discovered in Taipei city in 1992. As of 31 January 1997, 178 buildings with 1537 dwellings were found to contain ⁶⁰Co-contaminated rebars. Almost all contaminated reinforced concrete buildings were constructed between 1982 and 1984. Thousands of inhabitants had been exposed to ionising radiation of various degrees. Preliminary assessments by the Atomic Energy Council showed that the accumulated maximal doses ranged from a few mSv to several Sv. More reliable individual doses for 24 highly contaminated dwellings were later reconstructed by us for epidemiologic and medical purposes. This reconstruction was made by a large scale deployment of thermoluminescence dosemeters in the contaminated dwelling and by a consideration of the variation in residential daily activities for individual family members. In the present work, the reconstructed dose uncertainty is estimated by analysing the non-uniform exposure rates of the dwelling using isodose contour plots and by assigning different occupancy factors to different areas in each contaminated room. The non-uniform exposure rate and the occupancy factor are the main factors causing the dose reconstruction uncertainty. The total dose uncertainty is within a factor of two for all inhabitants living in the 24 contaminated dwellings studied. (author)

[en] We calculate single pion production by neutrinos in the resonance region. We consider both charged and neutral current reactions on free protons and neutrons. We present differential and total cross sections which can be compared with experiments. Then we use these results to calculate the spectra of the emerging pions including the Pauli suppression factor and rescattering corrections for reactions in heavy nuclei. Our results will be useful for studying single pion production and for investigating neutrino oscillations in future experiments

[en] We calculate the neutrino induced cross sections relevant for oscillation experiments, including the τ-lepton threshold for quasielastic, resonance and deep-inelastic scattering. In addition to threshold effects, we include nuclear corrections for heavy targets which are moderate for quasielastic and large for single pion production. The nuclear effects for deep-inelastic reactions are small. We present cross sections together with their nuclear corrections for various channels which are useful for interpreting the experimental results and for determining parameters of the neutrino sector. Finally, we calculate the τ-lepton event rates for the OPERA LBL experiment

[en] Rotational excitation and reorientation of a hydrogen molecule by collision with a ¹S atom are calculated using a time-dependent coupled channel wave packet method in the interaction representation. The method leads to functions analogous to the radical functions of the time-independent coupled channel method. S-Matrices and cross sections are obtained by propagation of these functions in real time

[en] We present a calculation of single pion electroproduction cross sections on heavy targets in the kinematic region of the Δ(1232) resonance. Final state interactions of the pions are taken into account using the pion multiple scattering model of Adler, Nussinov and Paschos (ANP model). For electroproduction and neutral current reactions we obtain results for carbon, oxygen, argon and iron targets and find a significant reduction of the W-spectra for π⁰ as compared to the free nucleon case. On the other hand, the charged pion spectra are only little affected by final state interactions. Measurements of such cross sections with the CLAS detector at JLAB could help to improve our understanding of pion rescattering effects and serve as important/valuable input for calculations of single pion neutrino production on heavy targets relevant for current and future long baseline neutrino experiments. Two ratios, in Eq. (3.8) and (3.10), will test important properties of the model. (authors)

[en] We consider resonance production by neutrinos focusing on the dominant resonance P₃₃ at low energies with a detailed discussion of its form factors. The results are presented for free nucleon targets. The Δ resonance is described by two form factors C₃^V and C₅^A and its differential cross sections are compared with experimental data. Further, we apply this approach to the electroproduction case and calculate its differential cross sections which are compared with electroproduction experimental data. Our approach to the analysis of Δ resonance is particularly simple and self-contained such that it could be helpful for the physical interpretation

[en] The muon energy spectra of the quasi-elastic and 1-pion production events in a LBL experiment, like K2K, are predicted to follow closely the neutrino energy spectrum, with downward shifts of the energy scale by < Q² > /2M and (< Q² > + M_Δ² - M²)/2M respectively. These predictions seem to agree with the observed muon spectra in the K2K nearby detector. The corresponding muon spectra in the faraway (SK) detector are predicted to show characteristic spectral distortions induced by ν_μ oscillation. Comparison of the predicted spectral distortions with the observed muon spectra of the 1-Ring and 2-Ring muon events in the SK detector will help to determine the oscillation parameters. The results will be applicable to other LBL experiments as well. (orig.)

[en] We provide a comprehensive comparison of W"± / Z vector boson production data in pPb and PbPb collisions at the LHC with predictions obtained using the nCTEQ15 PDFs. We identify the measurements which have the largest potential impact on the PDFs, and estimate the effect of including these data using a Bayesian reweighting method. We find this data set can provide information as regards both the nuclear corrections and the heavy flavor (strange quark) PDF components. As for the proton, the parton flavor determination/separation is dependent on nuclear corrections (from heavy target DIS, for example), this information can also help improve the proton PDFs.

[en] Highlights: •Surface barrier effects on AC loss were studied by simulations. •Surface and bulk region is characterized by different critical current density. •Simulation results are similar to the experimental results. -- Abstract: Influences of surface barrier in Ag–Bi2223 tapes on AC loss are studied. The Ag–Bi2223 tape is described by a surface region (near to the silver) and a bulk region, which are depicted by different critical current densities j_cs and j_cb, respectively. Simulations using the flux creep model indicate that with surface barrier increasing, a kink then a dip appear in the AC loss and the peak and dip positions move to higher magnetic fields. The results can be used as an effective method to qualitatively estimate the surface barrier strength

[en] We study nuclear effects of charged current deep inelastic neutrino-iron scattering in the framework of a X² analysis of parton distribution functions (PDFs). A set of iron PDFs are extracted and used to compute x_Bj-dependent and Q²-dependent nuclear correction factors which are required in global analyses of free nucleon PDFs. We compare our results with nuclear correction factors from neutrino-nucleus scattering models and correction factors for l^±-iron scattering. Except for very high x_Bj, our correction factors differ in both shape and magnitude from the correction factors of the models and charged-lepton scattering.
