On an atom with a magnetic quadrupole moment in a rotating frame

The quantum description of an atom with a magnetic quadrupole moment in the presence of a uniform effective magnetic field is analysed. The atom is also subject to rotation and a scalar potential proportional to the inverse of the radial distance. It is shown that the spectrum of energy is modified, in contrast to the Landau-type levels, and there is a restriction on the possible values of the cyclotron frequency which stems from the influence of the rotation and scalar potential proportional to the inverse of the radial distance.Comment: 11 pages. arXiv admin note: text overlap with arXiv:1705.0819

Simple Non-Markovian Microscopic Models for the Depolarizing Channel of a Single Qubit

The archetypal one-qubit noisy channels ---depolarizing, phase-damping and amplitude-damping channels--- describe both Markovian and non-Markovian evolution. Simple microscopic models for the depolarizing channel, both classical and quantum, are considered. Microscopic models which describe phase damping and amplitude damping channels are briefly reviewed.Comment: 13 pages, 2 figures. Title corrected. Paper rewritten. Added references.

Low-momentum interactions in three- and four-nucleon scattering

Low momentum two-nucleon interactions obtained with the renormalization group method and the similarity renormalization group method are used to study the cutoff dependence of low energy 3N and 4N scattering observables. The residual cutoff dependence arises from omitted short-ranged 3N (and higher) forces that are induced by the renormalization group transformations, and may help to estimate the sensitivity of various 3N and 4N scattering observables to short-ranged many-body forces.Comment: 5 pages, 8 figures, to be published in Phys.

Evaluation of Nutrition Intervention in the Senior Population

Average life expectancy has steadily increased with each passing year and is estimated to continue increasing in years to come. Reports show that the number of people aged 65 or older has increased from 6% of the population in the 1960’s, to 12% in the year 2000, to 16% of the total population in 2015.1 This number is expected to increase to almost 20% of the population by the year 2050.1 Striving towards healthy aging can help the growing senior population to live the best possible life in their later years. Nutrition education is one area of learning and practice that can help enhance the life of the geriatric population. Recent research suggests that national and state-sponsored programs that provide nutrition education and information to elders will help increase health of elders and reduce government medical costs for this population.3 This pilot study analyzed the effect of nutrition intervention in a senior living facility to determine if a positive change occurred in nutrition awareness, education, and behavior in the senior population at the residence. The six-seminar nutrition series was delivered over a period of 6 months and the residents were asked to take part in a survey at the conclusion of the last seminar. Based on both paired and unpaired t-tests, the findings support a statistically significant change in the senior population of this study. Further research and nutrition programs are needed to assure that the nutritional knowledge and needs of the elder population are being met

Giant FAZ10 is required for flagellum attachment zone stabilization and furrow positioning in Trypanosoma brucei

The flagellum and flagellum attachment zone (FAZ) are important cytoskeletal structures in trypanosomatids, being required for motility, cell division and cell morphogenesis. Trypanosomatid cytoskeletons contain abundant high molecular mass proteins (HMMPs), but many of their biological functions are still unclear. Here, we report the characterization of the giant FAZ protein, FAZ10, in Trypanosoma brucei, which, using immunoelectron microscopy, we show localizes to the intermembrane staples in the FAZ intracellular domain. Our data show that FAZ10 is a giant cytoskeletal protein essential for normal growth and morphology in both procyclic and bloodstream parasite life cycle stages, with its depletion leading to defects in cell morphogenesis, flagellum attachment, and kinetoplast and nucleus positioning. We show that the flagellum attachment defects are probably brought about by reduced tethering of the proximal domain of the paraflagellar rod to the FAZ filament. Further, FAZ10 depletion also reduces abundance of FAZ flagellum domain protein, ClpGM6. Moreover, ablation of FAZ10 impaired the timing and placement of the cleavage furrow during cytokinesis, resulting in premature or asymmetrical cell division
