AMBER

AMBER (an acronym for Assisted Model Building with Energy Refinement) is a family of force fields for molecular dynamics of biomolecules originally developed by Peter Kollman's group at the University of California, San Francisco. AMBER is also the name for the molecular dynamics software package that simulates these force fields. It is maintained by an active collaboration between David Case at Rutgers University, Tom Cheatham at the University of Utah, Tom Darden at NIEHS, Ken Merz at Michigan State University, Carlos Simmerling at Stony Brook University, Ray Luo at UC Irvine, and Junmei Wang at Encysive Pharmaceuticals.

Force field

The term "AMBER force field" generally refers to the functional form used by the family of AMBER force fields. This form includes a number of parameters; each member of the family of AMBER force fields provides values for these parameters and has its own name.

Functional form

The functional form of the AMBER force field is

$+\sum _{\text{torsions}}\sum _{n}{\frac {1}{2}}V_{n}[1+\cos(n\omega -\gamma )]$ $+\sum _{j=1}^{N-1}\sum _{i=j+1}^{N}f_{ij}{\biggl \{}\epsilon _{ij}{\biggl [}\left({\frac {r_{0ij}}{r_{ij}}}\right)^{12}-2\left({\frac {r_{0ij}}{r_{ij}}}\right)^{6}{\biggr ]}+{\frac {q_{i}q_{j}}{4\pi \epsilon _{0}r_{ij}}}{\biggr \}}$

Note that despite the term force field, this equation defines the potential energy of the system; the force is the derivative of this potential with respect to position.

Amber (processor core)

The Amber processor core is an open-source ARM-compatible 32-bit RISC processor. It is hosted on the OpenCores website and is part of a movement to develop a library of open source hardware intellectual property. The Amber core is fully compatible with the ARMv2 instruction set and is therefore supported by the GNU toolchain. This older version of the ARM instruction set is supported because it is not covered by patents so can be implemented without a license from ARM Holdings, unlike some previous open source projects. The Amber project provides a complete embedded FPGA system incorporating the Amber core and a number of peripherals, including UARTs, timers and an Ethernet MAC.

There are two versions of the core provided in the Amber project. The Amber 23 has a 3-stage pipeline, a unified instruction and data cache, a Wishbone interface, and is capable of 0.75 DMIPS per MHz. The Amber 25 has a 5-stage pipeline, separate data and instruction caches, a Wishbone interface, and is capable of 1.0 DMIPS per MHz. Both cores implement exactly the same ISA and are 100% software compatible.

Microsoft SharePoint Workspace

Microsoft SharePoint Workspace, previously known as Microsoft Office Groove, is a discontinued desktop application designed for document collaboration in teams with members who are regularly off-line or who do not share the same network security clearance. It is no longer included with Microsoft Office 2013 or Office 365, the latter of which includes Microsoft's OneDrive for Business instead. The latter does not fully replace the former.

Groove's uses have included coordination between emergency relief agencies where different organizations do not share a common security infrastructure and where offline access is important, and amongst teams of knowledge workers, such as consultants who need to work securely on client sites. It is also used as a staging system for documents in development, where content can be developed then transferred to a portal when complete.

Groove was initially developed by Lotus Notes creator Ray Ozzie, and developed by Groove Networks of Beverly, Massachusetts, until Microsoft's acquisition of Groove Networks in March 2005.

Groove (album)

"Groove" (full title Les McCann Presents the Dynamid Jazz Organ of Richard "Groove" Holmes with Ben Webster, Les McCann, Tricky Lofton, Ron Jefferson & George Freeman) is the debut led by organist Richard "Groove" Holmes recorded in 1961 and released on the Pacific Jazz label.

Reception

The Allmusic review by Scott Yanow states: "the result is a loose, enjoyable jam session. In addition to Holmes' appealing organ and McCann's typically funky piano, a major bonus is the brilliant playing of tenor saxophonist Ben Webster, whose tone was at its most gorgeous during this period".
