Syntactic closure. In computer science, syntactic closures are an implementation strategy for a hygienic macro system. The term pertains to the Scheme programming language.

When a syntactic closure is used the arguments to a macro call are enclosed in the current environment, such that they cannot inadvertently reference bindings introduced by the macro itself.

Andrews Cargo Module. The Andrews Cargo Module was a proposed design for an unmanned resupply spacecraft which would deliver cargo to the International Space Station (ISS). Andrews Space proposed to NASA that spacecraft of this design be used for the Commercial Orbital Transportation Services (COTS) program.  The proposal was ultimately rejected in favor of the SpaceX Dragon and the Orbital Sciences Cygnus.

Design 
The spacecraft consists of a common Service Module, a Pressurized Cargo Module (PCM) or an Unpressurized Cargo Module (UCM), and a Recovery Module.

Associated launch vehicle 
The spacecraft was to be launched on the proposed Hercules launch vehicle.

Cheminée du Front de Seine. The Cheminée du Front-de-Seine is a chimney located in the 15th arrondissement, in the Grenelle district of Paris. It is 130 metres high and the tallest structure in the district by 30 metres.

The chimney was designed by François Stahly and was built between 1970 and 1971. Its simple white form is unadorned except for aesthetic vents located in top of the structure.

Usage 

The chimney ventilates smoke from six boilers used to produce steam from low-sulfur fuel oil, which is distributed through underground pipes to the buildings of the district for central heating and as domestic hot water. It is overseen by the Parisian Company of District Heating (CPCU).

Its output is 590 tons of steam per hour. Ordinarily, only four boilers are used. The last two are only used during cold weather or to substitute for unavailable boilers in the CPCU network.

In 2016, the boiler house underwent renovations in order to function using biodiesel instead of fuel oil. The boiler's efficiency was improved by 5% to 8% and the amount of pollutants released was decreased by a factor of 10.

Aquatic garden 
The chimney is accompanied by an aquatic garden on the roof of the boiler house, which was designed by Catherine Stahly-Mougin, the daughter of the sculptor.

However, seepage of stagnant water from the pools, due to a lack of drainage for rainwater and watertight sealing, led the pools to be emptied in 1995 and, later, to a full renovation of the gardens.

Ornithology 
A birdbox was installed on the chimney in 1994 after a pair of Common kestrels was spotted nesting atop the chimney. The nest was abandoned in the years that followed.

In March 2013, a pair of Peregrine falcons returned in Paris for the first time in decades, in the same birdbox installed nearly 20 years before. The nest is under camera surveillance, and the couple had 3 chicks in the spring of 2013.

Ubiquitous robot. Ubiquitous robot is a term used in an analogous way to ubiquitous computing.  Software useful for "integrating robotic technologies with technologies from the fields of ubiquitous and pervasive computing, sensor networks, and ambient intelligence".

The emergence of mobile phone, wearable computers and ubiquitous computing makes it likely that human beings will live in a ubiquitous world in which all devices are fully networked. The existence of ubiquitous space resulting from developments in computer and network technology will provide motivations to offer desired services by any IT device at any place and time through user interactions and seamless applications. This shift has hastened the ubiquitous revolution, which has further manifested itself in the new multidisciplinary research area, ubiquitous robotics. It initiates the third generation of robotics following the first generation of the industrial robot and the second generation of the personal robot.

Ubiquitous robot (Ubibot) is a robot incorporating three components including virtual software robot or avatar, real-world mobile robot and embedded sensor system in surroundings. Software robot within a virtual world can control a real-world robot as a brain and interact with human beings. Researchers of KAIST, Korea describe these three components as a Sobot (Software robot), Mobot (Mobile robot), and Embot (Embedded robot).

Johnsen–Rahbek effect. The Johnsen–Rahbek effect occurs when an electric potential is applied across the boundary between a metallic surface and the surface of a semiconducting material or a polyelectrolyte.  Under these conditions an attractive force appears, whose magnitude depends on the voltage and the specific materials involved. The attractive force is much larger than would be produced by Coulombic attraction.

The effect is named after Danish engineers F. A. Johnsen and K. Rahbek, the first to investigate the effect at length.

Copper sweetening. Copper sweetening is a petroleum refining process using a slurry of clay and cupric chloride to oxidize mercaptans. The resulting disulfides are less odorous and usually very viscous, and are usually removed from the lower-boiling fractions and left in the heavy fuel oil fraction.

Copper sweetening introduces trace amount of copper into the resulting products, which tends to have detrimental effects as it leads to formation of gummy residues. Other sources of copper include contact with refinery parts made of copper and copper alloys. Copper is one of the most active instability promoters, and concentrations as low as 0.1 ppm can have marked negative effect. To combat these, metal deactivators are added to some fuels.

CASA C-102. 

The CASA C-102 was a military trainer aircraft designed in Spain in the late 1970s but never actually built. The project was initiated by a 1977 request to CASA by the Ejército del Aire for such an aircraft. The company's response was a conventional all-metal monoplane with a T-tail, fixed tricycle undercarriage and side-by-side seating for the pilot and instructor.

At the end of the following year, the Air Force commenced the formal tendering process for the Futuro Avión Ligero Selectivo ("Future Selective Light Aircraft"), to which CASA submitted a developed and refined version of the design, now known as the C-102S. The company had also laid out a four-seat utility version as the C-102SE.

Interest by the Air Force waned after this, and no order for the aircraft was placed. It was to be a full decade before the Ejército del Aire filled this niche with a modern aircraft, which would eventually be the Chilean ENAER Pillán built under licence by CASA.

Boron triiodide. Boron triiodide is a chemical compound of boron and iodine with chemical formula BI3. It has a trigonal planar molecular geometry.

Preparation 
Boron triiodide can be prepared by the reaction of boron with iodine at 209.5 °C or 409.1 °F.
It can also be prepared by reacting hydroiodic acid with boron trichloride:

  (reaction requires high temperature)

Another method is by reacting lithium borohydride with iodine. As well as boron triiodide, this reaction also produces lithium iodide, hydrogen and hydrogen iodide:

Properties 
In its pure state, boron triiodide forms colorless, otherwise reddish, shiny, air and hydrolysis-sensitive crystals, which have a hexagonal crystal structure (a = 699.09 ± 0.02 pm, c = 736.42 ± 0.03 pm, space group P63/m (space group no. 176)). Boron triiodide is a strong Lewis acid and soluble in carbon disulfide.

Boron triiodide reacts with water and decomposes to boric acid and hydriodic acid:

 

Its dielectric constant is 5.38 and its heat of vaporization is 40.5 kJ/mol. At extremely high pressures, BI3 becomes metallic at ~23 GPa and is a superconductor above ~27 GPa.

Applications 
Boron triiodide can be used to produce other chemical compounds and as a catalyst (for example in coal liquefaction).

Paul Zimmermann (mathematician). Paul Zimmermann (born 13 November 1964) is a French computational mathematician, working at INRIA.

Education
After engineering studies at École Polytechnique 1984 to 1987, he got a master's degree in computer science in 1988 from University Paris VII and a magister from École Normale Supérieure in mathematics and computer science. His doctoral degree from École Polytechnique in 1991 was entitled Séries génératrices et analyse automatique d’algorithmes, and advised by Philippe Flajolet.

Research
His interests include asymptotically fast arithmetic.  

He has developed some of the fastest available code for manipulating polynomials over GF(2), and for calculating hypergeometric constants to billions of decimal places. He is associated with the CARAMEL project to develop efficient arithmetic, in a general context and in particular in the context of algebraic curves of small genus; arithmetic on polynomials of very large degree turns out to be useful in algorithms for point-counting on such curves. He is also interested in computational number theory. In particular, he has contributed to some of the record computations in integer factorisation and discrete logarithm.

Zimmermann co-authored the book Computational Mathematics, published in 2018 on SageMath used by Mathematical students worldwide.

In 2010, he co-authored a book on algorithms for computer arithmetic with Richard Brent.  

He has been an active developer of the GMP-ECM implementation of the elliptic curve method for integer factorisation and of MPFR, an arbitrary precision floating point library with correct rounding. He is also a coauthor of the CADO-NFS software tool, which was used to factor RSA-240 in record time.

In a 2014 blog post, Zimmermann said that he would refuse invitations to review papers submitted to gold (author-pays) open access and hybrid open access journals, because he disagrees with the publication mechanism.
