Structure of the T4 baseplate and its function in triggering sheath contraction

Henning Paul-Julius Stahlberg, Petr Leiman, Ricardo Cesar Guerrero Ferreira, Christopher Browning, Nikolai Prokhorov

Several systems, including contractile tail bacteriophages, the type VI secretion system and R-type pyocins, use a multiprotein tubular apparatus to attach to and penetrate host cell membranes. This macromolecular machine resembles a stretched, coiled spri ...

Harnessing the damping properties of materials for high-speed atomic force microscopy

Jürgen Brugger, Georg Fantner, Adrian Pascal Nievergelt, Blake William Erickson, Jonathan David Adams, Jonas Grossenbacher

The success of high-speed atomic force microscopy in imaging molecular motors1, enzymes2 and microbes3 in liquid environments suggests that the technique could be of significant value in a variety of areas of nanotechnology. However, the majority of atomic ...

An Investigation of Muscle Models for Physiologically Based Intonation Modelling

Philip Neil Garner

Prosody is a crucial aspect of the speech signal and its modelling is of great importance for various speech technologies. Intonation models based on physiology rely on an accurate model of muscle activation. Although most of them are based on the spring-d ...

Injection Device

Yves Perriard, Romain David Besuchet

An injection deviee for injecting injection material, comprising: an elastic deformable element (3) able to exert a pushing force on a piston (20) of a syringe (2) so as to eject a quantity of injection material out of the syringe (2); a stopper ( 4) for r ...

Toward development of a biomimetic tensegrity footbridge

Ian Smith, Nicolas Willy Veuve, Seif Dalil Safaei

Biomimetic structures interact with their environment, change their properties, learn and self-repair, thereby providing properties that are similar to living organisms. Interactions with the environment involve unique challenges in the field of computatio ...

In-Plane Fabricated Insulated Gold-Tip Probe For Electrochemical And Molecular Experiments

Nico de Rooij, Terunobu Akiyama, Sebastian Gautsch, Peter Van der Wal, Yexian Wu

In this contribution we present a scanning probe with a gold-tip completely encapsulated with insulator all the way to the apex. The probe fabrication is unique owing to an in-plane arrangement in which the width of the cantilever is defined by deep reacti ...
