The MINERvA experiment is designed to perform precision studies of neutrino-nucleus scattering using $\nu_\mu$ and ${\bar\nu}_\mu$ neutrinos incident at 1-20 GeV in the NuMI beam Fermilab. This article presents a detailed description \minerva detector describes {\em ex situ} techniques employed characterize monitor its performance. comprised finely-segmented scintillator-based inner tracking region surrounded by electromagnetic hadronic sampling calorimetry. upstream portion includes planes...
We report a study of muon neutrino charged-current quasi-elastic events in the segmented scintillator inner tracker MINERvA experiment running NuMI beam at Fermilab. The were selected by requiring {\mu}^- and low calorimetric recoil energy separated from interaction vertex. measure flux-averaged differential cross-section, d{\sigma}/dQ^2, particle content final state. Deviations are found between measured d{\sigma}/dQ^2 expectations model independent nucleons relativistic Fermi gas. also...
We have isolated muon anti-neutrino charged-current quasi-elastic interactions occurring in the segmented scintillator tracking region of MINERvA detector running NuMI neutrino beam at Fermilab. measure flux-averaged differential cross-section, d{\sigma}/dQ^2, and compare to several theoretical models scattering. Good agreement is obtained with a model where nucleon axial mass, M_A, set 0.99 GeV/c^2 but vector form factors are modified account for observed enhancement, relative free case,...
Three-dimensional (3D) printing offers the promise of fabricating optical phantoms with arbitrary geometry, but commercially available thermoplastics provide only a small range physiologically relevant absorption (µa) and reduced scattering (µs`) values. Here we demonstrate customizable acrylonitrile butadiene styrene (ABS) filaments for dual extrusion 3D tissue mimicking phantoms. µa µs` values were adjusted by incorporating nigrosin titanium dioxide (TiO2) in filament process. A wide...
Our institution delivers TBI using a modified Theratron 780 60Co unit. Due to limitations of our treatment planning system in calculating dose for this treatment, we have developed fast Monte Carlo code calculate distributions within the patient. The algorithm is written C and uses voxel density information from CT images heterogeneous media. To test algorithm, film-based measurements were made separately simple water phantom with high-density insert RANDO then compared doses calculated by...
We report a case of patient with marked eosinophilia and neutrophilia as manifestation spindle cell sarcoma.A 41-year-old African American woman presented an enlarging, painful mass in her right knee area. Four years previously, she had similar to this diagnosed osteosarcoma, undergone radical resection hinge-knee replacement. Before the surgery, was treated neoadjuvant docetaxel gemcitabine. A biopsy taken from recurrent mass, histological examination revealed high-grade soft-tissue...
We studied the effects of image formation in a device known as Ferrocell, which consists thin film ferrofluid solution between two glass plates subjected to an external magnetic field presence light source. Following suggestions found literature, we compared Ferrocell scattering for some configurations with conical by structures foams Plateau borders, and discuss this type concept diffracted rays from Geometrical Theory Diffraction. For certain configurations, point source creates images...
Observing the light passing through a thin layer of ferrofluid, we can see occurrence interesting effects, both in formation patterns within ferrofluid and dispersion outside that layer. This leads us to ask what explanations associated with these effects are. In this paper, analyze explain luminous using Ferrolens, commercially known as Ferrocell. We present details our experimental apparatus, followed by discussion some properties polarization its relation magnetic contours produced...
We have explored some features of the complex fluids present in Earth’s atmosphere by observation optical phenomena and compared them to observed gems magnetic materials. The main feature a fluid is that it contains polyatomic structures such as polymer molecules or colloidal grains. This paper includes setups using tabletop experiments, which are intended show concretely principles discussed, giving sense how well idealizations treated apply atmospheric systems. sundogs, light pillars, halo...

The ferrocell is an optical viewing device that interacts with a magnetic field and one or more light sources to produce real-time visual display. Although this has been extensively studied by several researchers, proper computer simulation replicating effect not yet presented. Using numerical methods the law of reflection, was developed shows patterns as seen in are primarily caused reflections off ferrofluid nano-particles self organize into needle-like filaments align along flux lines...
This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate imaging field lines. We deduce that magnetically induced photonic band gap arrays similar electrostatic liquid crystal operation are responsible photographed images seek mathematically prove dipole nature. A simple way explaining this work is think old iron filling experiments; but now each molecule floating in liquid....
