Using New Technologies for Library Instruction in Science and Engineering: Web 2.0 Applications “Quantum computation is... a distinctively new way of harnessing nature... It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes.” … David Deutsch, The Fabric of Reality: the Science of Parallel Universes-- and its Implications http://en.wikiquote.org/wiki/David_Deutsch INTRODUCTION The transformational concept of Web 2.0 for libraries was a hot topic at three major conferences in June of 2006. The American Library Association (ALA), Special Libraries Association (SLA), and the American Society for Engineering Education (ASEE) conferences all had sessions on the subject. Not all of the focus was on sci-tech libraries. An exploration of the use of these technologies for library instruction in science and engineering fields is the emphasis for this column. -

Bowick, Luca Giomi, Homin Shin, and Creighton K. Thomas Department of Physics, Syracuse University, Syracuse New York, 13244-1130 We investigate crystalline order on a two-dimensional paraboloid of revolution by assembling a single layer of millimeter-sized soap bubbles on the surface of a rotating liquid, thus extending the classic work of Bragg and Nye on planar soap bubble rafts. Topological constraints require crystalline configurations to contain a certain minimum number of topological defects such as disclinations or grain boundary scars whose structure is analyzed as a function of the aspect ratio of the paraboloid. We find the defect structure to agree with theoretical predictions and propose a mechanism for scar nucleation in the presence of large Gaussian curvature. Soft materials such as amphiphilic membranes, diblock any triangulation of M reads copolymers and colloidal emulsions can form ordered structures with a wide range of complex geometries and Q = X(6 ci)+ X (4 ci)=6χ , (1) − − topologies. -

PHYS 624: Crystal Structures and Symmetry 1 Crystal Structures and Symmetry Introduction to Solid State Physics http://www.physics.udel.edu/∼bnikolic/teaching/phys624/phys624.html PHYS 624: Crystal Structures and Symmetry 2 Translational Invariance • The translationally invariant nature of the periodic solid and the fact that the core electrons are very tightly bound at each site (so we may ignore their dynamics) makes approximate solutions to many-body problem ≈ 1021 atoms/cm3 (essentially, a thermodynamic limit) possible. Figure 1: The simplest model of a solid is a periodic array of valance orbitals embedded in a matrix of atomic cores. Solving the problem in one of the irreducible elements of the periodic solid (e.g., one of the spheres in the Figure), is often equivalent to solving the whole system. PHYS 624: Crystal Structures and Symmetry 3 From atomic orbitals to solid-state bands • If two orbitals are far apart, each orbital has a Hamiltonian H0 = εn, where n is the orbital occupancy ⇐ Ignoring the effects of electronic corre- lations (which would contribute terms proportional to n↑n↓). + +++ ... = Band E Figure 2: If we bring many orbitals into proximity so that they may exchange electrons (hybridize), then a band is formed centered around the location of the isolated orbital, and with width proportional to the strength of the hybridization PHYS 624: Crystal Structures and Symmetry 4 From atomic orbitals to solid-state bands • Real Life: Solids are composed of elements with multiple orbitals that produce multiple bonds. Now imagine what happens if we have several orbitals on each site (ie s,p, etc.), as we reduce the separation between the orbitals and increase their overlap, these bonds increase in width and may eventually overlap, forming bands. -

Quasicrystals a New Kind of Symmetry Sandra Nair First, Definitions
Quasicrystals A new kind of symmetry Sandra Nair First, definitions ● A lattice is a poset in which every element has a unique infimum and supremum. For example, the set of natural numbers with the notion of ordering by magnitude (1<2). For our purposes, we can think of an array of atoms/molecules with a clear sense of assignment. ● A Bravais lattice is a discrete infinite array of points generated by linear integer combinations of 3 independent primitive vectors: {n1a1 + n2a2 + n3a3 | n1, n2, n3 ∈ Z}. ● Crystal structures = info of lattice points + info of the basis (primitive) vectors. ● Upto isomorphism of point groups (group of isometries leaving at least 1 fixed point), 14 different Bravais lattice structures possible in 3D. Now, crystals... ● Loosely speaking, crystals are molecular arrangements built out of multiple unit cells of one (or more) Bravais lattice structures. ● Crystallographic restriction theorem: The rotational symmetries of a discrete lattice are limited to 2-, 3-, 4-, and 6-fold. ● This leads us to propose a “functional” definition: A crystal is a material that has a discrete diffraction pattern, displaying rotational symmetries of orders 2, 3, 4 and 6. ● Note: Order 5 is a strictly forbidden symmetry → important for us. Tessellations aka tilings Now that we have diffraction patterns to work with, we consider the question of whether a lattice structure tiles or tessellates the plane. This is where the order of the symmetry plays a role. The crystals are special, as they display translational symmetries. As such, the tiling of their lattice structures (which we could see thanks to diffraction patterns) are periodic- they repeat at regular intervals. -

In order to implement a Java macro you will need to write 2 classes: • One that representing the allowed parameters, including mandatory parameters, default values, parameter descriptions. An instance of this class will be automatically populated when the user calls the macro in wiki syntax. • Another one that is the macro itself and implements the Macro interface. The XWiki Rendering Architecture can be summarized by the image below: The Parser parses a text input like "xwiki/2.0" syntax or HTML and generates an XDOM object. This object is an Abstract Syntax Tree which represents the input into structured blocks. The Renderer takes an XDOM as input and generates an output like "xwiki/2.0" syntax, XHTML or PDF. The Transformation takes an XDOM as input and generates a modified one. -

Wikis in Companies
CONSULTING WIKIS IN COMPANIES Collect, use and expand your knowledge. /WIKI HOW COMPANIES CAN BENEFIT FROM EVERY EMPLOYEE’S KNOWLEDGE WHY DO COMPANIES NEED WIKIS? Your intranet contains lots of information – but just how quickly can your employees find this information? And how quickly can they modify data? How much time do they spend dealing with e-mail messages popping up, and how efficient is their preparation for meetings and projects? How uncomplicated can new employees access important process knowledge? How much know-how at your company is unstructured or even unmapped? “IN 2009, IT IS PREDICTED THAT AT LEAST 50% OF ALL COMPANIES WILL BE UTILIZING Many intranets lack editorial dynamism and “up-to-dateness”. Information can sometimes become outdated extremely quickly, partially because employees – due to lacking aesthetics or complicated administration procedures – do not participate. The daily flood of e-mail WIKIS AS A VITAL INSTRUMENT is also inefficient and is an obstacle for companies: Often enough, information goes missing, or employees are confronted with information that is irrelevant. In addition, information becomes spread about, stored unused in mailboxes and various databanks that may be accessed only FOR COLLABORATION.” by a few employees. This inefficient form of communication and know-how management slows down companies, WILL YOU BE ONE OF THEM? leads to knowledge loss, and wastes resources. This is why companies need wikis. A wiki allows professional, systematic and uncomplicated knowledge management; it also allows Society for Information Management’s Advanced Practices employees to communicate actively and efficiently regarding the topics of the day. With a wiki, the entire know-how of a company can be mapped, actively used, and organically expanded. -
