In the presence of both spin-orbit scattering and a magnetic field the conductance of a chaotic GaAs quantum dot displays quite a rich behavior. Using a Hamiltonian derived by Aleiner and Fal’ko [Phys. Rev. Lett. 87, 256801 (2001)] we calculate the weak localization correction and the covariance of the conductance, as a function of parallel and perpendicular magnetic field and spin-orbit coupli...

The fluorescence light emitted by a 4-level system in J = 1/2 to J = 1/2 configuration driven by a monochromatic laser field and in an external magnetic field is studied. We show that the spectrum of resonance fluorescence emitted on the π transitions shows a signature of spontaneously generated interference effects. The degree of interference in the fluorescence spectrum can be controlled by m...

A turbulent boundary-layer flow over a rough wall generates a dipole sound field as the near-field hydrodynamic disturbances in the turbulent boundary-layer scatter into radiated sound at small surface irregularities. In this paper, phased microphone arrays are applied to the measurement and simulation of surface roughness noise. The radiated sound from two rough plates and one smooth plate in ...

Health literacy continues to experience the normal growing pains of an emerging field of inquiry and practice. The evolving concept of health literacy requires the development of new measurement tools in order to adequately study interventions and identify best practices. This article describes a multi-stage process of engaging the largest known international group of health literacy profession...

We realize indirect partial measurement of a transmon qubit in circuit quantum electrodynamics by interaction with an ancilla qubit and projective ancilla measurement with a dedicated readout resonator. Accurate control of the interaction and ancilla measurement basis allows tailoring the measurement strength and operator. The tradeoff between measurement strength and qubit backaction is charac...

| An algorithm for the determination of the dominant paths for indoor wave propagation is presented. The algorithm computes a tree of the relations between the rooms inside the building and the branches of the tree are used for the determination of the dominant paths. Based on these dominant paths, three different prediction models are presented and compared with one another and with measuremen...

MR imagers with magnetic fields (B0) greater than 1.5 T are offered by all major manufacturers. Although 4-, 6-, 7-, and even 8-T, whole-body instruments are currently operational, the most common high-B0 systems are the nearly 100 installed with 3-T magnets. The demand for bigger B0 systems has been driven almost exclusively by functional MR imaging (1); however, their proliferation and Food a...

The problem of locating a mobile terminal has received significant attention in the field of wireless communications. Time-ofarrival (TOA), received signal strength (RSS), time-difference-of-arrival (TDOA), and angle-of-arrival (AOA) are commonly used measurements for estimating the position of the mobile station. In this paper, we present a constrained weighted least squares (CWLS) mobile posi...
