Singularity is a new operating system produced by Microsoft Research. The design of Singularity is a marked departure from current commodity operating systems such as Windows or Linux. This paper presents and implementation of the Linux ext2 file system for use on Singularity. This project allows the design of Singularity to be evaluated. The development and testing described in this paper show...

In a paper titled "A topologically related singularity suggests a maximum preferred size for protein domains" (Zbilut et al., Proteins 2007;66:621-629), Zbilut et al. claim to have found a singularity in certain geometrical properties of protein structures, and suggest that this singularity may limit the maximum size of protein domains. They find further support for the singularity in their ana...

The possibility of having discrete degrees of freedom at singularities associated to ‘conifolds with discrete torsion’ is studied. We find that the field theory of D-brane probes near these singularities is identical to ordinary conifolds, so that there are no additional discrete degrees of freedom located at the singularity. We shed light on how the obstructions to resolving the singularity ar...

Kohn's singularity in dense electron systems is shown to give rise to instability against Cooper pair formation for large orbital momentum I , i.e. for I %r;':* -while for dilute systems ( r , S 1) pairing with 1 = 1 is predicted. It has long been known (Kohn and Luttinger 1965) that in dilute Fermi gas the use of an expansion for a bare vertex for a Cooper channel in powers of the gas paramete...
