Background: The nuclear fission process is a dramatic example of the large-amplitude collective motion in which nucleus undergoes series shape changes before splitting into distinct fragments. This can be represented by pathway many-dimensional space coordinates. Within stationary framework rooted static Schr\"odinger equation, action along determines spontaneous half-lives as well mass and cha...

The adaptive response to a given metabolic load during energy deficiencies varies considerably among animals. The aim of this study was to investigate if individual cows respond in a repeated manner to a negative energy balance (NEB) in early and mid-lactation. Twenty-five multiparous Holstein dairy cows (3.0 ± 1.1 parities; mean ± SD) experienced a NEB during the first weeks of lactation, and ...

The activation energies associated with the formation of a superlattice intrinsic stacking fault (SISF) from an antiphase domain boundary (APB) and the formation of a superlattice extrinsic stacking fault (SESF) from a complex stacking fault (CSF) in g 0 phase of Ni-based superalloys are calculated using a microscopic phase field dislocation model in combination with the nudged elastic band (NE...

The halo masses of nearby individual elliptical galaxies can be estimated by using the kinematics of their stars, planetary neb-ulae, and globular clusters—ideally in combination. With currently improving coverage of galaxies of ordinary luminosities and morphologies , systematic trends may be identified. Bright, boxy ellipticals show strong signatures of dark matter, while faint, disky ones ty...

Jonah Preston, a five-year-old boy with a history of asthma, was brought to triage by his mother early one morning with a chief complaint of “difficulty breathing.” (This case is a composite based on our experience.) Ms. Preston reported that her son had recently been sneezing and had a runny nose. Over night, he’d begun to cough, finally waking her at 5 am complaining that he couldn’t breathe....
