A Model-Driven Engineering Approach for ROS using Ontological Semantics
This paper presents a novel ontology-driven software engineering approach for
the development of industrial robotics control software. It introduces the
ReApp architecture that synthesizes model-driven engineering with semantic
technologies to facilitate the development and reuse of ROS-based components
and applications. In ReApp, we show how different ontological classification
systems for hardware, software, and capabilities help developers in discovering
suitable software components for their tasks and in applying them correctly.
The proposed model-driven tooling enables developers to work at higher
abstraction levels and fosters automatic code generation. It is underpinned by
ontologies to minimize discontinuities in the development workflow, with an
integrated development environment presenting a seamless interface to the user.
First results show the viability and synergy of the selected approach when
searching for or developing software with reuse in mind.Comment: Presented at DSLRob 2015 (arXiv:1601.00877), Stefan Zander, Georg

Aorto-subclavian thromboembolism: a rare complication associated with moderate ovarian hyperstimulation syndrome
The case of an arterial aorto-subclavian thromboembolism associated with a moderate ovarian hyperstimulation syndrome (OHSS) and following ovulation induction for in-vitro fertilization in a young woman is reported. Because of the lack of response to systemic thrombolysis, a left postero-lateral thoracotomy was performed on day 8 after embryo transfer. A fibrinocruoric embolus situated at the junction of the left subclavian artery from the aorta was removed through a left subclavian arteriotomy. The distal axillary embolus was removed by a retrograde balloon catheter embolectomy. A moderate OHSS was observed. The ovarian stimulation and OHSS-related risks of thromboembolism are discussed. We conclude that, in the absence of risk factors, counselling about possible complications resulting from stimulation must be emphasize
Science from an Ultra-Deep, High-Resolution Millimeter-Wave Survey
Opening up a new window of millimeter-wave observations that span frequency
bands in the range of 30 to 500 GHz, survey half the sky, and are both an order
of magnitude deeper (about 0.5 uK-arcmin) and of higher-resolution (about 10
arcseconds) than currently funded surveys would yield an enormous gain in
understanding of both fundamental physics and astrophysics. In particular, such
a survey would allow for major advances in measuring the distribution of dark
matter and gas on small-scales, and yield needed insight on 1.) dark matter
particle properties, 2.) the evolution of gas and galaxies, 3.) new light
particle species, 4.) the epoch of inflation, and 5.) the census of bodies
orbiting in the outer Solar System.Comment: 5 pages + references; Submitted to the Astro2020 call for science

Material Codes: Ephemeral Traces
New forms of digital imaging such as GPS and satellite mapping have had significant impact on our collective senses of orientation in space and time. Similarly, digital software such as that used for Jacquard weaving allow for new forms of collage, superimposing, combining, repetition, and fragmenting of imagery, which further disrupt a stable perspective. This article links concepts of global data circulation and collection with contemporary data visualization and materialization approaches in the field of digital humanities.
Kelly Thompsonâs multifaceted project Material Codes: Ephemeral Traces, established in 2014, translates various forms of data through digitally assisted Jacquard weaving. With data visualization, the artistâs subjective process of beautification can make an audience feel emotionally engaged by the rendering of phenomena that may otherwise be beyond the scale of human senses. What is beyond reach becomes tangible. In Thompsonâs research-creation work, the intangible concept of digital data is both visualized and materialized into the literally tangible, as tactile cloth. This conversation between Janis Jefferies, (London, UK) and Kelly Thompson (Montreal, Canada) over a period of 10 months proposes questions around code, data, image, weaving, and research engagement

Primordial Non-Gaussianity
Our current understanding of the Universe is established through the pristine
measurements of structure in the cosmic microwave background (CMB) and the
distribution and shapes of galaxies tracing the large scale structure (LSS) of
the Universe. One key ingredient that underlies cosmological observables is
that the field that sources the observed structure is assumed to be initially
Gaussian with high precision. Nevertheless, a minimal deviation from
Gaussianityis perhaps the most robust theoretical prediction of models that
explain the observed Universe; itis necessarily present even in the simplest
scenarios. In addition, most inflationary models produce far higher levels of
non-Gaussianity. Since non-Gaussianity directly probes the dynamics in the
early Universe, a detection would present a monumental discovery in cosmology,
providing clues about physics at energy scales as high as the GUT scale
