In this paper we present recent results obtained in the Nanobiotechnology and Spintronics group of  the LNEES research center of Politecnico di Milano, partially in cooperation with the nanoGUNE center in Spain, in the field of lab-on-chip devices based on magnetic nanostructures.

I will discuss some recent computer simulations of three different systems; nematic shells, sticky colloidal particles on surfaces and the bulk phases of liquid crystalline bolaamphiphiles. For nematic shells, a layer of liquid crystal is used to coat a microscopic particle. In this geometry, defects necessarily occur – the system is frustrated so that the director profile and local orientational ordering is not constant everywhere. We examine the interactions between the defects for a number of different types and shapes of particles and other cavities. I will also discuss sticky colloids on a...

We will address some basic questions related to the light forces on small (Rayleigh) particles, which are usually described as the sum of two terms: the dipolar or gradient force and the scattering or radiation pressure force. The scattering force is traditionally considered proportional to the Poynting vector, which gives the direction and magnitude of the momentum flow. However, as we will show, when the light field has a non- uniform spatial distribution of spin angular momentum there is an additional  non-conservative force term is proportional to the curl of the spin angular momentum of...

Nonlinear dynamics has the feature that it is conceptually and mathematically challenging and yet ubiquitous in its applications. Indeed, one of the appeals of the subject is the universality of some of its frameworks and results. We are attempting to take advantage of such wide applicability in order to involve an unusual range of participants in nonlinear dynamics research. This range spans from postdoctoral to K-12 students as well as teachers.

Cavity optomechanics is rapidly developing into a major area of research.  This is a result of the developments from two converging perspectives on the physical world. From the top down perspective, ultra-sensitive micromechanical and nanomechanical detectors have become available utilizing the advanced materials and processing techniques of the semiconductor...

I will give an overview of a program to map the space of configurations of binary compact coalescences, starting for preliminary indications a couple of years ago that the problem is amenable to reduced order modeling. I will then give an overview of Reduced Basis, our results obtained so far and a roadmap for the future.  Essentially, the core issue is how to chose the most relevant points in parameter space, in a nearly optimal way, and to select which configurations are "the most representative ones". This applies to the case in which the emitted gravitational waves can be simply evaluated using closed form approximations or obtained by solving simple equations but,...

Biosketch: Dr. David Ballantyne obtained his Ph.D. in 2002 from the University of Cambridge, and has been an Assistant Professor at the
Center for Relativistic Astrophysics in the School of Physics since 2008.  His research concentrates on topics in high-energy astrophysics
with an emphasis on interpreting existing data and making predictions for future observations. His main interests are the evolution of
galaxies and their central supermassive black...

Extreme-mass-ratio binaries, composed of a small compact object (SCO) and supermassive black hole (SMBH), are eventual observational candidates for future space-based gravitational wave observatories.  Theoretically, these binaries are examples of the as-yet not thoroughly solved two-body problem in general relativity.  Extreme-mass-ratio inspiral (EMRI) calculations proceed by using black hole perturbation theory.  The gravitational field of the small mass affects its own orbit in the background geometry,...

Sebastian Thrun recently left Stanford University and started Udacity. Udacity is an online university that seeks to reach the 99% of the world population that are presently excluded from high-quality higher education. The first class on Artificial Intelligence, jointly offered with Stanford, attracted 160,000 students, of which 23,000 graduated with Stanford-level qualifications. The speaker will discuss his experience with traditional forms of education, and brainstorm how higher education may look like in the digital age.

Thrun is co-founder of Udacity, a Google VP, and a Stanford Research Professor. At Google, he runs Google X, home to the Google self-driving car...
