Potential of Constraining Propagation Parameters of Galactic Cosmic Rays with the High Energy cosmic-Radiation Detection facility onboard China's Space Station

Precise measurements of the spectra of secondary and primary cosmic rays are crucial for understanding the origin and propagation of those energetic particles. The High Energy cosmic-Radiation Detection (HERD) facility onboard China`s Space Station, which is expected to operate in 2027, will push the direct measurements of cosmic ray fluxes precisely up to PeV energies. In this work, we investigate the potential of HERD on studying the propagation of cosmic rays using the measurements of boron, carbon, and oxygen spectra. We find that, compared with the current results, the new HERD measurements can improve the accuracy of the propagation parameters by 8\% to 40\%. The constraints on the injection spectra at high energies will also be improved.Comment: 10 pages, 4 figure

Bis(4-amino-2-chloro­phen­yl) disulfide

The title compound, C12H10Cl2N2S2, features an S—S bond [2.0671 (16) Å] that bridges two 4-amino-2-chloro­phenyl rings with a C—S—S—C torsion angle of −84.2 (2)°. The two benzene rings are twisted with respect to each other at a dihedral angle of 39.9 (2)°. Inter­molecular N—H⋯S hydrogen bonding is present in the crystal structure

PELVIS-SHOULDER MOVEMENT VARIABILITY AND CUETIP MOTION DURING THE WARM-UP AND FINAL STROKES IN POOL

The purpose of this study was to investigate the variation and variability of cuetip, shoulder and pelvis on stop shot, push shot and draw shot during warm-up strokes (W3, W2, W1) and final stroke (FS). Eight cameras were used to determine three-dimensional motions of cue, shoulder and pelvis for a pool world cup championships winner. The results showed that the largest variation was presented in the final stroke as well as the greatest consistence through trials. Variation of shoulder and pelvis was supposed an essential factor for a pool shoot. The cuetip, shoulder, and pelvis all demonstrate the similar pattern with greatest variability in first warm stoke and greatest consistence on the final stroke. The variability will converge to from the warm-up strokes to the final stroke

Experimental Test of Tracking the King Problem

In quantum theory, the retrodiction problem is not as clear as its classical counterpart because of the uncertainty principle of quantum mechanics. In classical physics, the measurement outcomes of the present state can be used directly for predicting the future events and inferring the past events which is known as retrodiction. However, as a probabilistic theory, quantum-mechanical retrodiction is a nontrivial problem that has been investigated for a long time, of which the Mean King Problem is one of the most extensively studied issues. Here, we present the first experimental test of a variant of the Mean King Problem, which has a more stringent regulation and is termed "Tracking the King". We demonstrate that Alice, by harnessing the shared entanglement and controlled-not gate, can successfully retrodict the choice of King's measurement without knowing any measurement outcome. Our results also provide a counterintuitive quantum communication to deliver information hidden in the choice of measurement.Comment: 16 pages, 5 figures, 2 table

Angular Reconstruction of a Lead Scintillating-Fiber Sandwiched Electromagnetic Calorimeter

A new method called Neighbor Cell Deposited Energy Ratio (NCDER) is proposed to reconstruct incidence position in a single layer for a 3-dimensional imaging electromagnetic calorimeter (ECAL).This method was applied to reconstruct the ECAL test beam data for the Alpha Magnetic Spectrometer-02 (AMS-02). The results show that this method can achieve an angular resolution of 7.36\pm 0.08 / \sqrt(E) \oplus 0.28 \pm 0.02 degree in the determination of the photons direction, which is much more precise than that obtained with the commonly-adopted Center of Gravity(COG) method (8.4 \pm 0.1 /sqrt(E) \oplus 0.8\pm0.3 degree). Furthermore, since it uses only the properties of electromagnetic showers, this new method could also be used for other type of fine grain sampling calorimeters.Comment: 6 pages, 8 figure
