Rocking Rotation of a Rigid Disk Embedded in a Transversely Isotropic Half-Space

The asymmetric problem of rocking rotation of a circular rigid disk embedded in a finite depth of a transversely isotropic half-space is analytically addressed. The rigid disk is assumed to be in frictionless contact with the elastic half-space. By virtue of appropriate Green's functions, the mixed boundary value problem is written as a dual integral equation. Employing further mathematical tec...

Three speeds of gene repositioning

Yeast use at least three different strategies to regulate how transcription factors position genes within the nucleus, < a d d a r t t y p e = " r e l " d o i = " 1 0. 1 0 8 3 / j c b. 2 0 1 5 0 8 0 6 8 " > Randise-Hinchliff et al.< / a d d a r t > reveal. In budding yeast, many genes are recruited to nuclear pore complexes when they are induced, potentially hastening the export of transcribed ...

Reducing Disk Rotation Delays using Range Writes

Disk I/O is generally considered the bottleneck in memory operations. This is generally due to mechanical limitations (limited disk rotation caps transfer bandwidth), and the general architecture of modern disks (rotating platters accessed by a single head on the arm), which causes a delay on the positioning of the head. Operating systems are generally able to fight the seek delays by writing t...

Dark Matter Halos and Disk Rotation Curves

Cosmological N–body simulations have revealed a remarkable similarity in the structure of dark matter halos formed in hierarchically clustering universes. Regardless of halo mass, cosmological parameters, and power spectrum of initial density fluctuations, the spherically averaged density profiles of dark matter halos have a universal shape. The logarithmic slope of this profile is shallower th...
