TL;DR: In this article, the embedding of the SM hypercharge into an orientifold gauge group is studied, and possible embeddings are classified, and a systematic construction of bottom-up configurations and top-down orientiferold vacua is achieved, solving the tadpole conditions in the context of Gepner orientifolds.

TL;DR: In this article, a new application of Split Hopkinson Pressure Bar (SHPB) for testing honeycombs is presented, where Viscoelastic bars are used to improve the accuracy of measurements and a generalised two-strain measurement method is applied to obtain a sufficient measurable maximum crush (up to 80%).

TL;DR: In this paper, two LHCf detectors, consisting of imaging calorimeters made of tungsten plates, plastic scintillator and position sensitive sensors, are installed at zero degree collision angle ±140 m from an interaction point (IP).
Abstract: LHCf is an experiment dedicated to the measurement of neutral particles emitted in the very forward region of LHC collisions. The physics goal is to provide data for calibrating the hadron interaction models that are used in the study of Extremely High-Energy Cosmic-Rays. This is possible since the laboratory equivalent collision energy of LHC is 1017 eV. Two LHCf detectors, consisting of imaging calorimeters made of tungsten plates, plastic scintillator and position sensitive sensors, are installed at zero degree collision angle ±140 m from an interaction point (IP). Although the lateral dimensions of these calorimeters are very compact, ranging from 20 mm × 20 mm to 40 mm × 40 mm, the energy resolution is expected to be better than 6% and the position resolution better than 0.2 mm for γ-rays with energy from 100 GeV to 7 TeV. This has been confirmed by test beam results at the CERN SPS. These calorimeters can measure particles emitted in the pseudo rapidity range η > 8.4. Detectors, data acquisition and electronics are optimized to operate during the early phase of the LHC commissioning with luminosity below 1030 cm-2 s-1. LHCf is expected to obtain data to compare with the major hadron interaction models within a week or so of operation at luminosity ~ 1029 cm-2 s-1. After ~ 10 days of operation at luminosity ~ 1029 cm-2 s-1, the light output of the plastic scintillators is expected to degrade by ~ 10% due to radiation damage. This degradation will be monitored and corrected for using calibration pulses from a laser.

TL;DR: In this paper, an uncoupled non-associated fracture model is proposed which makes use of a stress state dependent weighting function and an anisotropic plastic strain measure, which is obtained from applying the von Mises equivalent plastic strain definition after the linear transformation of the plastic strain tensor.
