A hybrid ion-atom trap with integrated high resolution mass spectrometer
(Review of Scientific Instruments, 2019-10-01)© 2019 Author(s). In this article, we describe the design, construction, and implementation of our ion-atom hybrid system incorporating a high resolution time of flight mass spectrometer (TOFMS). Potassium atoms (39K) in ... -
A Modular Multilevel Series/Parallel Converter for a Wide Frequency Range Operation
(IEEE Transactions on Power Electronics, 2019-10-01)When providing ac output, modular multilevel converters (MMCs) experience power fluctuation in the phase arms. The power fluctuation causes voltage ripple on the module capacitors, which grows with the output power and inversely ... -
All That Twitters Is Not Gold: How Verbally Documenting or Reflecting During or After an Experience Can Affect Enjoyment
(2013)Social media and mobile technology now provide consumers with the opportunity to continuously document or reflect on their moment-to-moment internal and external experiences. For instance, "tweets" are often written while ... -
An energy stable C0 finite element scheme for a quasi-incompressible phase-field model of moving contact line with variable density
(Journal of Computational Physics, 2020-03-15)In this paper, we focus on modeling and simulation of two-phase flow problems with moving contact lines and variable density. A thermodynamically consistent phase-field model with general Navier boundary condition is developed ... -
Analyzing X-ray tomographies of granular packings.
(The Review of scientific instruments, 2017-05)Starting from three-dimensional volume data of a granular packing, as, e.g., obtained by X-ray Computed Tomography, we discuss methods to first detect the individual particles in the sample and then analyze their properties. ... -
Artificial Intelligence for added value in the creation, implementation, and evaluation of national export strategies
(2022-04-22)A National Export Strategy (NES) is an action plan that sets priorities, allocates resources, and specifies actions to strengthen an economy’s international trade capabilities, seeking to enhance its economic growth and ... -
Association of pre-treatment radiomic features with lung cancer recurrence following stereotactic body radiation therapy.
(Physics in medicine and biology, 2019-01-08)The purpose of this work was to investigate the potential relationship between radiomic features extracted from pre-treatment x-ray CT images and clinical outcomes following stereotactic body radiation therapy (SBRT) for ... -
Automatic word count estimation from daylong child-centered recordings in various language environments using language-independent syllabification of speech
(Speech Communication, 2019-10-01)© 2019 The Authors Automatic word count estimation (WCE) from audio recordings can be used to quantify the amount of verbal communication in a recording environment. One key application of WCE is to measure language input ... -
Building Church Community in a Digital Age
(2019)This paper examines how individuals’ social interactions are influenced by the media environments they inhabit (Media Ecology) and the consequent impact on the practice of developing community in the local church (Ecclesiology). ... -
Chiral quasiparticle tunneling between quantum Hall edges in proximity with a superconductor
(Physical Review B, 2019-09-10)© 2019 American Physical Society. We study a two-terminal graphene Josephson junction with contacts shaped to form a narrow constriction, less than 100nm in length. The contacts are made from type-II superconducting contacts ... -
Compiling Inequalities: Computerization in the British Civil Service and Nationalized Industries, 1940-1979
(2009)In the 1950s and early 1960s, Great Britain's computing industry led the world in the development and application of computers for business and administrative work. The British government and civil service, paragons ... -
Computer aided restoration of handwritten character strokes
(CAD Computer Aided Design, 2017-08-01)© 2017 Elsevier Ltd This work suggests a new variational approach to the task of computer aided segmentation and restoration of incomplete characters, residing in a highly noisy document image. We model character strokes ... -
Correction of beam hardening in X-ray radiograms.
(The Review of scientific instruments, 2019-02)The intensity of a monochromatic X-ray beam decreases exponentially with the distance it has traveled inside a material; this behavior is commonly referred to as Beer-Lambert's law. Knowledge of the material-specific attenuation ... -
Creating linked datasets for SME energy-assessment evidence-building: Results from the U.S. Industrial Assessment Center Program
(Energy Policy, 2017-12-01)© 2017 Elsevier Ltd Lack of information is commonly cited as a market failure resulting in an energy-efficiency gap. Government information policies to fill this gap may enable improvements in energy efficiency and social ... -
Detecting a Majorana-fermion zero mode using a quantum dot
(Physical Review B - Condensed Matter and Materials Physics, 2011-11-16)We propose an experimental setup for detecting a Majorana zero mode consisting of a spinless quantum dot coupled to the end of a p-wave superconducting nanowire. The Majorana bound state at the end of the wire strongly influences ... -
Detecting photon-photon interactions in a superconducting circuit
(Physical Review B - Condensed Matter and Materials Physics, 2015-10-06)A local interaction between photons can be engineered by coupling a nonlinear system to a transmission line. The required transmission line can be conveniently formed from a chain of Josephson junctions. The nonlinearity ... -
Embodied Attention: Learning from the Wisdom of the Desert and Saint Augustine in an Age of Distraction
(2014)Throughout the life of the Church, certain habits have been cultivated to shape the identity of its community and deepen our communion with God. We see in the writings of the Desert Fathers that attentiveness is one habit ... -
