Free license

A free license or open license is a license which allows others to reuse another creator’s work as they wish. Without a special license, these uses are normally prohibited by copyright, patent or commercial license. Most free licenses are worldwide, royalty-free, non-exclusive, and perpetual (see copyright durations). Free licenses are often the basis of crowdsourcing and crowdfunding projects. The invention of the term "free license" and the focus on the rights of users were connected to the sharing traditions of the hacker culture of the 1970s public domain software ecosystem, the social and political free software movement (since 1980) and the open source movement (since the 1990s). These rights were codified by different groups and organizations for different domains in Free Software Definition, Open Source Definition, Debian Free Software Guidelines, Definition of Free Cultural Works and The Open Definition. These definitions were then transformed into licenses, using the copyright as legal mechanism. Ideas of free/open licenses have since spread into different spheres of society. Open source, free culture (unified as free and open-source movement), anticopyright, Wikimedia Foundation projects, public domain advocacy groups and pirate parties are connected with free and open licenses.

MRI characterization of in vitro clots at 3T and 7T: A technical note

Lijing Xin, François Lazeyras

In acute ischemic stroke, the composition of the occlusive clot can be associated with the underlying pathophysiology and the response to treatment. For these reasons, it is important to characterize the clot composition from clinical scans. We examine the ...

Invariant integrals on topological groups

Vasco Schiavo

We generalize the fixed-point property for discrete groups acting on convex cones given by Monod in [23] to topological groups. At first, we focus on describing this fixed-point property from a functional point of view, and then we look at the class of gro ...

Polymer Translocation through Nanometer Pores

Maria-Alexandra Paun

In this paper the loaded polymer transport and its escape via a nanometer size aperture, virtually by nanomembrane, the polymer being moved by an exterior electrostatic field, has been studied. Assuming a linear dependency of the friction coefficient on th ...

Definition of Free Cultural Works

The Definition of Free Cultural Works evaluates and recommends compatible free content licenses. The Open Content Project by David A. Wiley in 1998 was a predecessor project which defined open content. In 2003, Wiley joined the Creative Commons as "Director of Educational Licenses" and announced the Creative Commons and their licenses as successors to his Open Content Project. Therefore, Creative Commons' Erik Möller in collaboration with Richard Stallman, Lawrence Lessig, Benjamin Mako Hill, Angela Beesley, and others started in 2006 the Free Cultural Works project for defining free content.

Pirate Party

Pirate Party is a label adopted by political parties around the world. Pirate parties support civil rights, direct democracy (including e-democracy) or alternatively participation in government, reform of copyright and patent laws to make them more flexible and open to encourage innovation and creativity, use of free and open-source software, free sharing of knowledge (open content and open access), information privacy, transparency, freedom of information, free speech, anti-corruption, net neutrality and oppose mass surveillance, censorship and Big Tech.

Open source

Open source is source code that is made freely available for possible modification and redistribution. Products include permission to use the source code, design documents, or content of the product. The open-source model is a decentralized software development model that encourages open collaboration. A main principle of open-source software development is peer production, with products such as source code, blueprints, and documentation freely available to the public.
