We have calculated the equations of state, the viscosity and self-diffusion coefficients, and electronic transport coefficients of beryllium in the warm dense regime for densities from 4.0 to 6.0 g/cm(3) and temperatures from 1.0 to 10.0 eV by using quantum molecular dynamics simulations. The principal Hugoniot curve is in agreement with underground nuclear explosive and high-power laser experimental results up to ~20 Mbar. The calculated viscosity and self-diffusion coefficients are compared with the one-component plasma model, using effective charges given by the average-atom model. The Stokes-Einstein relationship, which connects viscosity and self-diffusion coefficients, is found to hold fairly well in the strong coupling regime. The Lorenz number, which is the ratio between thermal and electrical conductivities, is computed via Kubo-Greenwood formula and compared to the well-known Wiedemann-Franz law in the warm dense region.

Household waste is a hotspot of antibiotic resistance, which can be readily emitted to the ambient airborne inhalable particulate matters (PM) during the day-long storage in communities. Nevertheless, whether these waste-specific inhalable antibiotic resistance genes (ARGs) are associated with pathogenic bacteria or pose hazards to local residents have yet to be explored. By high-throughput metagenomic sequencing and culture-based antibiotic resistance validation, we analyzed 108 airborne PM and nearby environmental samples collected across different types of residential communities in Shanghai, the most populous city in China.

Radix entomolaris (RE) characterized by an extra root in mandibular molars is a rare phenotype. When this condition coincides with complex root canal curvatures or S-shaped canals, root canal therapy (RCT) challenges arise. The present study presents three cases of RE along with complex root curvatures.

Breast ultrasound has been established for many years as an important method in addition to mammography for clarifying breast findings. The goal of the Best Practice Guidelines Part III of the DEGUM breast ultrasound working group is to provide colleagues working in senology with information regarding the specific medical indications for breast ultrasound in addition to the current ultrasound criteria and assessment categories published in part I and the additional and optional sonographic diagnostic methods described in part II. The value of breast ultrasound for specific indications including follow-up, evaluation of breast implants, diagnostic workup of dense breast tissue, diagnostic workup during pregnancy and lactation, and the diagnostic workup of breast findings in men is discussed.
