Strashimirite. Strashimirite (IMA symbol: Ssh) is a rare monoclinic mineral containing arsenic, copper, hydrogen, and oxygen. It has the chemical formula .

This mineral was discovered in Zapachitsa (Zapacica) copper deposit, Svoge, Sofia Oblast, Bulgaria in 1960, by Bulgarian mineralogist Jordanka Minčeva-Stefanova. She named it after Strashimir Dimitrov (1892–1960), Professor in Mineralogy and Petrography at Sofia University "St Kliment Ohridski", Bulgaria. The International Mineralogical Association approved it as a new mineral in 1968.

It occurs as a secondary mineral phase in the oxidation zone of copper arsenide deposits. It occurs associated with tyrolite, cornwallite, clinoclase, euchroite, olivenite, parnauite, goudeyite, arthurite, metazeunerite, chalcophyllite, cyanotrichite, scorodite, pharmacosiderite, brochantite,
azurite, malachite and chrysocolla.

Although it remains quite rare, strashimirite has subsequently been identified in a number of locations including: Novoveska Huta in the Czech Republic; on the west flank of Cherbadung (Pizzo Cervandone), Binntal,
Valais, Switzerland; in Kamsdorf and Saalfeld, Thuringia, Germany; the Clara mine, near Oberwolfach, Black Forest, Germany; in the Richelsdorf Mountains, Hesse, Germany; Cap Garonne mine, near le Pradet, Var, and Triembach-au-Val, Haut-Rhin, France; Wheals Gorland and Unity, Gwennap, Cornwall, England; the Tynagh mine, near Loughrea, Co.
Galway, Ireland; the Majuba Hill mine, Antelope district, Pershing Co. Nevada, US;  and the Centennial Eureka mine, Tintic district, Juab Co., Utah, US.

Edwards Rhomboidal. The Edwards Rhomboidal was an early British aircraft of extremely unorthodox configuration designed by Arthur Henry Edwards.

Design and development
The Edwards Rhomboidal was an annular wing biplane with identical upper and lower surfaces consisting of four surfaces in a diamond arrangement, the aft wings being of three times the chord of the forward wings. It had been arrived at as a result of successful  experiments with a rubber-driven  model monoplane.  The main structure of the aircraft was formed by a pair of triangular section wire-braced trusses arranged one above another, connected by five sets of paired struts. Each  girder bore a pair of substantial flexibly mounted struts extending outwards, the wings being tensioned between the ends of the longitudinal girders and the outer ends of the struts by means of cables which formed the wing leading edges. The trailing edges were under less tension, the intention being that the wings would automatically deform to spread flight loads.  They had no internal spars, being stiffened by ribs aligned with the direction of flight sewn into pockets in the single thickness of fabric.  A rectangular elevator was mounted on the rearmost connecting struts, and a small rudder was mounted above the upper wing.  There was no provision for lateral control. It was powered by a 50 hp (37 kW) Humber water-cooled engine using chains to drive a pair of tractor propellers between the wings, with the pilot sitting behind the engine. The undercarriage consisted of a pair of skids each bearing a pair of wheels, supplemented by a castoring nosewheel and a tailskid.
   
It was tested at Brooklands during  early 1911, but there is no record of it having left the ground.

The Penguins of Madagascar (video game). The Penguins of Madagascar is a video game developed by Griptonite Games and released on Nintendo DS on November 2, 2010, with additional minigames utilizing the camera on Nintendo DSi systems. The game is based on DreamWorks and Nickelodeon's The Penguins of Madagascar animated television series, and is unrelated to DreamWorks' Penguins of Madagascar film. The game received a successor, The Penguins of Madagascar: Dr. Blowhole Returns – Again!, in September 2011 for most gaming platforms.

Overview 
The game's plot involves the penguins throwing King Julien a party, finding Mort, and removing snow from their zoo. Players must switch between each of the four penguins, or all of them stacked together, in order to traverse the overhead-angled environments and solve puzzles. The game also features unlockable minigames, allows players to adorn the penguins' hideout with decorations, and a Nintendo DSi exclusive-mode that lets King Julien critique photographs taken with the system's camera.

Critical reception 
Common Sense Media gave the game 4 stars out of 5, writing "The strategic puzzle-solving format is a fantastic way to bring The Penguins of Madagascar into the video game world. It was a pleasantly unexpected choice on the part of the developers, and such a better one than if they'd simply given us a game about penguins waddling along and smacking enemies. Kids will really have to put on their thinking caps for these fun, brain-teasing levels -- but remembering that the audience here will be younger kids, the developers didn't go crazy with any way-too-difficult challenges. They're all fun, but do-able -- which is great. And the invention-creating mini-games break things up nicely (although you will have to put together the same darn bridge way too many times). Along the way, you can collect snow cones that can be used to purchase mini-games, which also provides a nice break from the strategic planning." Kidsworld gave it 4/5 stars, writing " This is a great game that can be played for short intervals of time and then picked up at a later date".

Kinetic tournament. A Kinetic Tournament is a kinetic data structure that functions as a priority queue for elements whose priorities change as a continuous function of time. It is implemented analogously to a "tournament" between elements to determine the "winner" (maximum or minimum element), with the certificates enforcing the winner of each "match" in the tournament. It supports the usual priority queue operations - insert, delete and find-max. They are often used as components of other kinetic data structures, such as kinetic closest pair.

Implementation 
A kinetic tournament is organized in a binary tree-like structure, where the leaves contain the elements, and each internal node contains the larger (or smaller) of the elements in its child nodes. Thus, the root of the tree contains the maximum (or minimum) element at a given time. 
The validity of the structure is enforced by creating a certificate at each node, which asserts that the element in the node is the larger of the two children. When this certificate fails, the element at the node is changed (to be the element in the other child), and a new certificate representing the new invariant is created. If the element this node was a winner at its parent node, then the element and certificates at the parent must be recursively updated too.

Analysis 
This is a O(n) space, responsive, local, compact and efficient data-structure.
Responsiveness: A certificate failure will cause the creation of a new certificate to replace the old one, which must be put into the event queue. It may also trigger changes to the O(logn) certificates at its parent nodes. Each certificate change requires a delete and insert operation in the priority queue of events. Each of these takes O(log n) time, so the responsiveness, the total time required to process a certificate failure, is . While this is considered responsive in general, it is less responsive than other kinetic priority queues such as kinetic heaps which respond to certificate failures with O(1) certificate changes.
Locality: Each element is involved in O(logn) certificates (for example, the maximal element is involved in a certificate at each of its parents all the way up to the root node). Again, while this is considered local, a kinetic heap is much more local.
Compactness: This is a very compact structure, containing O(n) certificates - exactly one for every edge in the tree.
Efficiency: Kinetic heaps are very efficient, with the number of internal events (certificate changes) being only a factor of O(log n) more than the number of external events. Specifically, for a collection of space-time trajectories where each pair intersects at most  times, the kinetic tournament processes  events in  time, where   is a Davenport-Schinzel sequence. Additionally, insertions and deletions cause O(logn) certificate changes each. Each certificate change takes O(logn) time, which is determined by the time required to execute the event queue update.

Path integral molecular dynamics. Path integral molecular dynamics (PIMD) is a method of incorporating quantum mechanics into molecular dynamics simulations using Feynman path integrals. In PIMD, one uses the Born–Oppenheimer approximation to separate the wavefunction into a nuclear part and an electronic part. The nuclei are treated quantum mechanically by mapping each quantum nucleus onto a classical system of several fictitious particles connected by springs (harmonic potentials) governed by an effective Hamiltonian, which is derived from Feynman's path integral. The resulting classical system, although complex, can be solved relatively quickly. There are now a number of commonly used condensed matter computer simulation techniques that make use of the path integral formulation including centroid molecular dynamics (CMD), ring polymer molecular dynamics (RPMD), and the Feynman–Kleinert quasi-classical Wigner (FK–QCW) method. The same techniques are also used in path integral Monte Carlo (PIMC).

There are two ways to calculate the dynamics calculations of PIMD. The first one is the non-Hamiltonian phase space analysis theory, which has been updated to create an "extended system" of isokinetic equations of motion which overcomes the properties of a system that created issues within the community. The second way is by using Nosé–Hoover chain, which is a chain of variables instead of a single thermostat of variable.

Combination with other simulation techniques 

The simulations done my PIMD can broadly characterize the biomolecular systems, covering the entire structure and organization of the membrane, including the permeability, protein-lipid interactions, along with "lipid-drug interactions, protein–ligand interactions, and protein structure and dynamics."

Applications 

PIMD is "widely used to describe nuclear quantum effects in chemistry and physics".

Path Integral Molecular Dynamics can be applied to  polymer physics, both field theories, quantum and not, string theory, stochastic dynamics, quantum mechanics, and quantum gravity. PIMD can also be used to calculate time correlation functions

Simons Institute for the Theory of Computing. The Simons Institute for the Theory of Computing at the University of California, Berkeley is an institute for collaborative research in theoretical computer science.

History
Established on July 1, 2012 with a grant of $60 million from the Simons Foundation, the Institute is housed in Calvin Lab, a dedicated building on the Berkeley campus. The Simons Institute brings together the leading researchers in theoretical computer science and related fields, as well as the next generation of outstanding young scholars, to explore deep unsolved problems about the nature and limits of computation.

Richard M. Karp was Founding Director of the Institute, and fellow Turing Award winner Shafi Goldwasser took over as Director on January 1, 2018.

Mission 
The Institute aims to promote fundamental research on the foundations of computer science, as well as to expand the horizons of the field by exploring other scientific disciplines through a computational lens. This second and distinctive goal is motivated by the fact that natural phenomena in many scientific fields (including mathematics, statistics, physics, astronomy, biology and economics), or the models those fields have developed for these phenomena, are intrinsically computational in nature—from chemical processes in living cells to the self-organizing behavior of complex systems of interacting particles, to mechanisms governing human evolution and the collective behavior of competing agents in an economy. The insights gained from such explorations often reflect back to the theory of computation, opening new directions and advancing our understanding of fundamental issues in complexity theory and algorithms.

Activities 
The Institute's core activities revolve around a rotating sequence of programs; a program typically runs for one semester, and there will usually be two concurrent programs each semester. Run by a small group of organizers, a program typically includes 60-70 long-term participants (a mix of senior and junior researchers), with additional short-term visitors attending workshops during the semester. Junior participants are supported by the Fellowships program.

Program topics are intended to span all areas of theoretical computer science, as well as its connections to other scientific disciplines; the Institute particularly aims to identify programs that can potentially lead to substantial advances in the field, rather than promoting "business as usual".
