Symmetries and optical transitions of hexagonal quantum dots in GaAs/AlGaAs nanowires

Marc-André Dupertuis

We investigate the properties of electronic states and optical transitions in hexagonal GaAs quantum dots within Al0.3Ga0.7As nanowires, grown in axial direction [111]. Such dots are particularly interesting due to their high degree of symmetry. A streamli ...

Lagrangian Based Mathematical Modeling and Experimental Validation of a Planar Stabilized Platform for Mobile Systems

Mehmet Hasan Mutlu

Typical operating conditions for mobile sensor systems, and in particular mobile robots, exhibit a wide range of mechanical disturbances due their ego-motion. Sensor systems mounted on these mobile platforms often suffer to varying degrees from these distu ...

Spin-resolved optical conductivity of two-dimensional group-VIB transition-metal dichalcogenides

Nicola Marzari, Marco Gibertini

We present an ab initio study of the spin-resolved optical conductivity of two-dimensional (2D) group-VIB transition-metal dichalcogenides (TMDs). We carry out fully relativistic density-functional-theory calculations combined with maximally localized Wann ...

Merge and divert. (±)-goniomitine was synthesized featuring two key steps: a) fragment coupling to functionalized cyclopentene by a novel palladium-catalyzed decarboxylative vinylation reaction and b) an unprecedented one-pot integrated oxidation/reduction ...

In this research we study the berth allocation problem (BAP) in real time as disruptions occur. In practice, the actual arrival times and handling times of the vessels deviate from their expected or estimated values, which can disrupt the original berthing ...

Using a head-mounted camera to infer attention direction

Aude Billard

A head-mounted camera was used to measure head direction. The camera was mounted to the forehead of 20 6- and 20 12-month-old infants while they watched an object held at 11 horizontal (-80 degrees to + 80 degrees) and 9 vertical (-48 degrees to + 50 degre ...

Non-contact, 3D magnetic biomanipulation for in vivo and in vitro applications

Mahmut Selman Sakar

Micro/nano robots have the potential to revolutionize many aspects of medicine. These untethered, wirelessly controlled and powered devices will make existing therapeutic and diagnostic procedures less invasive and will enable new procedures never before p ...

Connected at any cost? The vulnerability of critical infrastructures and crisis management

Valérie November

Critical infrastructures are receiving a great deal of attention, due, on the one hand, to the major malfunctions to which they are subject and their potential as targets of malicious intent on the other. Economic and political impacts are studied; increas ...
