Ever since Chuck Berry coined the term "rocking pneumonia" in his 1956 song "Roll over Beethoven", pneumonia has been mentioned frequently in modern blues and rock songs. We analyzed the lyrics of these songs to examine how various elements of pneumonia have been represented in popular music, specifically the cause of pneumonia, the risk groups, comorbidity (such as the boogie woogie flu), the ...

Male Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) used their aristae to repeatedly tap the female, usually on her aristae, during the second stage of head rocking courtship. The male’s antennae moved in an apparently exploratory manner earlier in head rocking. Reduced rates of copulation followed removal of male and female aristae, supporting the idea that tapping with the aristae is a...

The analysis of double-crystal x-ray rocking curves of single-crystal layered structures can give valuable information on layer strains, displacement of atoms from normal lattice sites (which reduces the structure factor), crystallographic misorientations, and crystal defects. Both strains and misorientations cause shifts in the Bragg angle. These two effects are readily separated using two or ...

Shake table testing of a 1/5 scale model of a slender bridge steel truss pier that uses a controlled rocking approach as a means of seismic protection was conducted. The controlled rocking approach allows the pier to uplift from its base while passive energy dissipation devices steel yielding devices or fluid viscous dampers are implemented across the uplifting location to control the response....

Underwater acoustic propagation in the Arctic Ocean is characterized by a refractive surface-channel with a rough boundary. Scattering estimates based on freesurface theory have proven low by more than a factor of two in forward-scatter loss and low by 20 dB or more in backscatter strength. Failure to account for either attenuation or backscattering indicates that impedance effects must be invo...

The endocrine cytokine leptin is mainly secreted by white adipose tissue and plasma leptin levels positively correlate with body fat mass. Via its action on neurons in the hypothalamic arcuate nucleus (ARC), leptin regulates body weight by stimulating energy expenditure and inhibiting food intake. The main signaling pathway of the leptin receptor is the JAK2-STAT3 pathway. A recent publication ...

This paper proposes an impedance control method called the multi-point impedance control (MPIC) for redundant manipulators. The method can not only control end-effector impedance, but also regulate impedances of several points on the links of the manipulator, which are called virtual end-point impedances, utilizing arm redundancy. Two approaches for realizing the MPIC are presented. In the firs...

Fluid shear stress (FSS) is an important stimulus for cell functions. Compared with the well established parallel-plate and cone-and-plate systems, a rocking "see-saw" system offers some advantages such as easy operation, low cost, and high throughput. However, the FSS spatiotemporal pattern in the system has not been quantified. In the present study, we developed a lubrication-based model to a...

itotic spindle positioning involves a con-formational switch in LGN, the mammalian version of the invertebrate Pins protein, duces a spindle rocking that represents the first genetically manipulable model for studying spindle positioning in vertebrates. The switch operates via the opening of LGN, which can normally fold back onto itself. The unfolding is triggered by binding to either membrane-...
