Charm-strange baryon strong decays in a chiral quark model
The strong decays of charm-strange baryons up to N=2 shell are studied in a
chiral quark model. The theoretical predictions for the well determined
charm-strange baryons, , and , are in
good agreement with the experimental data. This model is also extended to
analyze the strong decays of the other newly observed charm-strange baryons
, , , and .
Our predictions are given as follows. (i) might be the first

Modeling of moisture diffusion in CFRP strengthened concrete based on thermal-moisture analogy
In this paper, the thermal-moisture analogy schemes were applied to simulate moisture diffusion in an epoxy resin and CFRP strengthened concrete system numerically. The two thermal-moisture analogy schemes were adopted for homogeneous material (e.g., epoxy adhesive) or multi-component material systems. The direct analogy (DA) is only valid for the homogeneous material system and can simulate the moisture diffusion in an epoxy adhesive accurately. The normalized analogy (NA) was proved be an effective tool for the CFRP-concrete system. In addition, based on NA, the interfacial stress and swelling stress induced by water can be simulated accuratel
