      In this manuscript we present details on the optimization, construction and performance of a wide-bore (71 mm) a-helical-cut notch-coil magnet with variable geometry for fast-field-cycling NMR. In addition to the usual ...
    • Algebraic functions in quasiprimal algebras 

      Campercholi, Miguel; Vaggione, Diego (2014)
      A function is algebraic on an algebra A if it can be implicitly defined by a system of equations on A. In this note we give a semantic characterization for algebraic functions on quasiprimal algebras. This characterization ...
    • Analysis of non-Markovian repairable fault trees through rare event simulation 

      Budde, Carlos E.; D'Argenio, Pedro Ruben; Monti, Raúl Enrique; Stoelinga, Mariëlle (2022)
      Dynamic fault trees (DFTs) are widely adopted in industry to assess the dependability of safety-critical equipment. Since many systems are too large to be studied numerically, DFTs dependability is often analysed using ...
    • Analysis of X-ray absorption spectra of the K and L 2,3 edges of GaN within the FP-LAPW method 

      Grad, Gabriela Beatriz; Bonzi, Edgardo Venusto (2016)
      Gallium nitride, GaN, is a semiconductor material with several technological applications and therapeutic potential to inhibits the proliferation of tumor cells. In this work we performed all electron self consistent ...
    • Analytical and rheological studies of modified gel dosimeters exposed to X-ray beams 

      Romero, Marcelo Ricardo; Mattea, Facundo; Vedelago, José; Chacón Obando, David; Valente, Mauro Andrés; Álvarez Igarzabal, Cecilia Inés; Strumia, Miriam Cristina (2016)
      The need to know the dose of X-rays to be applied to patients suffering diseases such as cancer requires accurate and stable dosimetric devices. Currently, the use of gelatin-based dosimeters has yielded excellent results ...
    • Anisotropy-based mechanism for zigzag striped patterns in magnetic thin films 

      Billoni, Orlando Vito; Bustingorry, S.; Barturen, M.; Milano, J.; Cannas, Sergio Alejandro (2014)
      In this work, we studied a two-dimensional ferromagnetic system using Monte Carlo simulations. Our model includes exchange and dipolar interactions, a cubic anisotropy term, and uniaxial out-of-plane and in-plane ones. ...
