• (2012)
<p>Flow in a hopper is both a fertile testing ground for understanding fundamental granular flow rheology and industrially highly relevant. Despite increasing research efforts in this area, a comprehensive physical theory ...
• (2010)
<p>This thesis focuses on the fluctuation in the switching current $I_s$ of superconducting Al nanowires. We discovered that the maximum current which nanowires can support is limited by a single phase slip at low temperature. ...
• (2013)
<p>Nanometer-scale metallic structures have been widely and intensively studied over the last decade because of their remarkable plasmonic properties that can enhance local electromagnetic (EM) fields. However, most plasmonic ...
• (2014)
<p>Granular impact, where a foreign object strikes a granular material like sand, is common in nature and industry. Due to experimental difficulties in obtaining sufficiently fast data at the scale of a single grain, a ...
• (2012)
<p>We report on graphene-based Superconductor-Normal metal-Superconductor Joseph- son junctions with contacts made from lead. The high transition temperature of this superconductor allows us to observe the supercurrent ...
• (2012)
<p>The lifetime of $^{19}$Ne is an important parameter in precision tests of the Standard Model. Improvement in the uncertainty of experimental observables of this and other $T=\frac{1}{2}$ mirror isotopes would allow for ...
• (2012)
<p>The mass of the $W$ boson is one of the most important parameters in the </p><p>Standard Model. A precise measurement of the $W$ boson mass, together </p><p>with a precise measurement ...
• (2013)
<p>A simultaneous measurement of three Standard Model cross-sections using 4.7 inverse femtobarns of proton-proton collision data at a center-of-mass energy of 7 TeV is presented. Collision data were collected using the ...

• (2013)
<p>Strong coupling between light and matter has been demonstrated both in classical</p><p>cavity quantum electrodynamics (QED) systems and in more recent circuit-QED</p><p>experiments. This enables the generation of strong ...
• (2010)
<p>&#65279;<p></p><p>Giant multipole resonances are a fundamental property of nuclei and</p><p>arise from the collective motion of the nucleons inside</p><p>the nucleus. Careful studies of these resonances and their ...
• (2014)
<p>Cells express a variety of proteins on their surface that allows them to sample the world. These proteins are embedded in the plasma membrane, a bilayer of lipids that surrounds the cell. Since the lipid and protein ...
• (2014)
<p>We describe the measurement of muon neutrino disappearance due to</p><p>neutrino oscillation using the Tokai-2-Kamiokande (T2K) experiment's Run 1-4 (6.57&times;10<super>20</super> POT)</p><p>data set. We analyze the ...
• (2010)
<p>Parton distribution functions (PDFs) provide important information about the flavor and spin structure of nucleon, which is one of the most fundamental building blocks of nature. Furthermore, they can also shed light ...

• (2008-03-19)
We present a measurement of ppbar->Zγ + X -> e<sup>+</sup>e<sup>-</sup>γ + X production using proton-antiproton collision data collected at the Collider Detector at Fermilab at a center of mass energy of 1.96 TeV. Zγ ...
• (2010)
<p>Measurements of the three-body photodisintegration of <super>3</super>He were performed at the High Intensity &gamma-ray Source (HI&gammaS). Neutrons emitted in this reaction inside a <super>3</super>He gas target were ...
• (2012)
<p>An experiment measuring the analyzing power A<sub>y</sub>(&theta;) for neutron&ndash;helium-3 (<italic>n</italic>-<super>3</super>He) elastic scattering over broad angular distributions for a range of incident neutron ...
• (2014)
<p>DNA origami is a novel self-assembly technique that can be used to form various </p><p>2D and 3D objects, and to position matter with nanometer accuracy. It has been </p><p>used to coordinate the placement of nanoscale ...
• (2013)
<p>The study of dynamics on networks has been a major focus of nonlinear science over the past decade. Inferring network properties from the nodal dynamics is both a challenging task and of growing importance for applied ...
