Nucleic acids have been used to create diverse synthetic structural and dynamic systems. Toehold-mediated strand displacement has enabled the construction of sophisticated circuits, motors, and molecular computers. Yet it remains challenging to demonstrate complex structural reconfiguration in which a structure changes from a starting shape to another arbitrarily prescribed shape. To address th...

INFRES, 46 rue Barrault, 75013 Paris, France EMail: [email protected] URL: http://www.enst.fr/-elc This paper presents “Ubit”, a new graphical toolkit that is based on the “brick construction game” model. This approach makes it possible to create sophisticated application-specific components by combining simple “basic bricks”. All...

The Multi-Chip-Module-Deposited (MCM-D) technique has been used to build hybrid pixel detector assemblies. This paper summarises the results of an analysis of data obtained in a test beam campaign at CERN. Here, single chip hybrids made of ATLAS pixel prototype read–out electronics and special sensor tiles were used. They were prepared by the Fraunhofer Institut für Zuverlässigkeit und Mikroint...

Brick-and-Mortar structures can exhibit exceptional combinations of properties, such as high strength and toughness. The properties are highly dependent on the failure regime, namely ability to distribute damage prior failure. In our recent work rectangular structures, we have identified a transition from localised damaged (called ‘two-peak’ failure) distributed ‘peak-plateau-peak’ failure), de...

Since the work of George Richardson on the problem of investment co-ordination, the literature has focused on explaining equilibrium in investment games and neglected the problem of how investments are co-ordinated. This paper reports the findings of a case study of the brick industry which used grounded theory techniques to develop a new analysis of investment coordination. Our main findings i...

The calculation of electromagnetic (EM) fields and waves inside finite-sized structures comprised of different media can benefit from a diakoptics method such as linear embedding via Green’s operators (LEGO). Unlike scattering problems, the excitation of EM waves within the bulk dielectric requires introducing sources inside the structure itself. To handle such occurrence, we have expanded the ...

This paper reports the results obtained with a group of 24 14-year-old students when presented with a set of algebra tasks by the Leeds Modelling System, LMS. These same students were given a comporoble paper-and-pencil test crud detailed interviews some four months later. The latter studies uncovered several kinds of student misunderstandings that LMS had not detected. Some students had profou...

We address a question posed by T. Sibley and Stan Wagon. They proved that rhombic Penrose tilings in the plane can be 3-colored, but a key lemma of their proof fails in the natural 3D generalization. In that generalization, an object is built from bricks, each of which is a parellelopiped, and they are glued face-toface. The question is: How many colors are needed to color the bricks of any suc...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...
