We report that a perpendicular magnetic field introduces an anomalous interaction correction, $\delta \sigma$, to the static conductivity of doped graphene in ballistic regime. The correction implies magnetoresistance, \rho_{xx}$ scales inversely with temperature \rho_{xx}(T) \propto 1/T$ parametrically large interval. When disorder is scalar-like, $\propto behavior leading contribution crossov...

The static horizontal position accuracy of a mapping-grade GNSS receiver was tested in two forest types over two seasons, and subsequently was tested in one forest type against open sky conditions in the winter season. The main objective was to determine whether the holding position during data collection would result in significantly different static horizontal position accuracy. Additionally,...

Echo planar imaging (EPI) suffers from geometric distortions caused by magnetic field inhomogeneities, which can be time-varying as a result of small amounts of head motion that occur over seconds and minutes during fMRI experiments, also known as "dynamic geometric distortion". Phase Labeling for Additional Coordinate Encoding (PLACE) is a promising technique for geometric distortion correctio...

We measured the improvement in retinal image quality provided by correcting the temporal variation in the eye's wave aberration with a closed-loop adaptive optics system. This system samples the eye's wave aberration at rates up to 30 Hz. Correction of the eye's aberrations can be completed in 0.25-0.5 seconds, resulting in residual rms wave-front errors as low as 0.1 microns for 6.8 mm pupils....

The drooping tip deformity is both a bothersome aesthetic feature and functional impairment of the nose. Both static and dynamic factors may affect tip appearance and it seems logical to take into account these factors when planning correction of drooping tip. Many studies have examined this topic, but its treatment remains controversial. In order to make nasal tip surgery successful, it is use...

This paper presents an adaptive protocol for packet-level forward error-correction in dynamic networks. The objective is to facilitate besl-eITort real-time applications whose timing constraints rule out the usc of retransmission-based ARQ schemes. The degree of redundancy is adjusted as a function of network stale, decreasing when the network is well-behaved and increasing when it is nolo The ...

The continued scaling of photolithographic fabrication techniques down to 32 nanometers and beyond faces enormous technology and economic barriers. Selfassembled devices such as silicon nanowires or carbon nanotubes show promise to not only achieve aggressive dimensions, but to help address power and other gating issues in system architecture, while potentially helping contain rampant increases...

Electrodynamics for self-interacting scalar elds in spatially at FriedmannRobertson-Walker space-times is studied. The corresponding one-loop eld equation for the expectation value of the complex scalar eld in the conformal vacuum is derived. For exponentially expanding universes, the equations for the Bogoliubov coe cients describing the coupling of the scalar eld to gravity are solved numeric...

This paper expands on previous work to introduce a high quality, but low cost attitude and heading reference system (AHRS), that is physically small, lightweight, and lowpower. Previous Work on the sensor has shown that for non-accelerating environments, this small low-cost sensor has a short term accuracy of approximately 4 ◦ in pitch, roll, and yaw. We extend the previous two-step non-linear ...

Thermodynamic properties of β-HMX crystal are investigated using the quasi-harmonic approximation and density functional theory within the local density approximation (LDA), generalized gradient approximation (GGA), and GGA + empirical van der Waals (vdW) correction. It is found that GGA well describes the thermal expansion coefficient and heat capacity but fails to produce correct bulk modulus...
