On Projections to the Pure Spinor Space

A family of covariant non-linear projections from the space of SO(10) Weyl spinors onto the space of pure SO(10) Weyl spinors is presented. The Jacobian matrices of these projections are related to a linear projector which was previously discussed in...

Treble, Bass, Alto, and Tenor Clefs in Music Reading and Notation

A treble clef (sometimes known as the G clef) tells you that the note G is on the second line from the bottom of the staff. See how the curly part of the treble clef wraps around that line?

Clef - Wikipedia

The three clef symbols used in modern music notation are the G-clef, F-clef, and C-clef. Placing these clefs on a line fixes a reference note to that line—an F-clef fixes the F below middle C, a C-clef fixes …

Nonlinear Dimensionality Reduction Methods in Climate Data Analysis

Linear dimensionality reduction techniques, notably principal component analysis, are widely used in climate data analysis as a means to aid in the interpretation of datasets of high dimensionality. These linear methods may not be appropriate for t...

Enhancing KiWi - Scalable Concurrent Key-Value Map

We take a relatively fresh wait-free, concurrent sorted map called KiWi, fix and enhance it. First, we test its linearizability by fuzzing and applying Wing&Gong [2] linearizability test. After fixing a few bugs in the algorithm design and its implem...

How do I get the current user's username in Bash?

If you want to get the fullname and not the user id, you can get from /etc/passwd and get your line with grep; or simpler with id -P which get the line for the current user; and, in all case, something like that:

The Dynamics of the Linear Random Farmer Model

On the framework of the Linear Farmer's Model, we approach the indeterminacy of agents' behaviour by associating with each agent an unconditional probability for her to be active at each time step. We show that Pareto tailed returns can appear ev...

Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN

We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z=0.24). In addition to PMN J0948+0022 (z=0.585), the first source of...
