Role and Discipline Relationships in a Transdisciplinary Biomedical Team: Structuration, Values Override and Context Scaffolding
Though accepted that "team science" is needed to tackle and conquer the
health problems that are plaguing our society significant empirical evidence of
team mechanisms and functional dynamics is still lacking in abundance. Through
grounded methods the relationship between scientific disciplines and team roles
was observed in a United States National Institutes of Health-funded (NIH)
research consortium. Interviews and the Organizational Culture Assessment
Instrument (OCAI) were employed.. Findings show strong role and discipline
idiosyncrasies that when viewed separately provide different insights into team
functioning and change receptivity. When considered simultaneously,
value-latent characteristics emerged showing self-perceived contributions to
the team. This micro/meso analysis suggests that individual participation in
team level interactions can inform the structuration of roles and disciplines
in an attempt to tackle macro level problems.Comment: Presented at COINs13 Conference, Chile, 2013 (arxiv:1308.1028
On a generalized Kirchhoff equation with sublinear nonlinearities
In this paper we consider a generalized Kirchhoff? equation in a bounded
domain under the effect of a sublinear nonlinearity. Under suitable assumptions
on the data of the problem we show that, with a simple change of variable, the
equation can be reduced to a classical semilinear equation and then studied
with standard tools.Comment: 13 page
Simple and efficient LCAO basis sets for the diffuse states in carbon nanostructures
We present a simple way to describe the lowest unoccupied diffuse states in
carbon nanostructures in density functional theory (DFT) calculations using a
minimal LCAO (linear combination of atomic orbitals) basis set. By comparing
plane wave basis calculations, we show how these states can be captured by
adding long-range orbitals to the standard LCAO basis sets for the extreme
cases of planar sp2 (graphene) and curved carbon (C60). In particular,
using Bessel functions with a long range as additional basis functions retain a
minimal basis size. This provides a smaller and simpler atom-centered basis set
compared to the standard pseudo-atomic orbitals (PAOs) with multiple
polarization orbitals or by adding non-atom-centered states to the basis.Comment: 3 pages, 3 figure
Fast scan control for deflection type mass spectrometers
A high speed scan device is reported that allows most any scanning sector mass spectrometer to measure preselected gases at a very high sampling rate. The device generates a rapidly changing staircase output which is applied to the accelerator of the spectrometer and it also generates defocusing pulses that are applied to one of the deflecting plates of the spectrometer which when shorted to ground deflects the ion beam away from the collector. A defocusing pulse occurs each time there is a change in the staircase output

Existence results of positive solutions for Kirchhoff type equations via bifurcation methods
In this paper we address the following Kirchhoff type problem
\begin{equation*}
\left\{ \begin{array}{ll}
-\Delta(g(|\nabla u|_2^2) u + u^r) = a u + b u^p& \mbox{in}~\Omega, u>0&
\mbox{in}~\Omega, u= 0& \mbox{on}~\partial\Omega,
\end{array} \right. \end{equation*} in a bounded and smooth domain
in . By using change of variables and bifurcation
methods, we show, under suitable conditions on the parameters and the
nonlinearity , the existence of positive solutions.Comment: 18 pages, 1 figur
The science-of-team-science, transdisciplinary capacity, and shifting paradigms for translational professionals
The Science-of-Team-Science (SciTS) has become an important area of study as collaborative research becomes more normative throughout science inquiry and especially in medical and healthcare sectors. Team science aims for higher and collaborative levels of inquiry that operate within economies of knowledge similar to transdisciplinarity that strive to synthesize knowledge and innovate as a result of newly developed and hybridized methods of approach. This newly becoming and normalizing mode of science will require professionals to be aware of and embrace the shifting realities which have been the consequence of this new economy of knowledge. The next century of inquiry will require new generations of translational professionals that are keenly aware of their role as part of the translational process no matter what role they presently play in the continuum of bench to bedside to storefront healthcare. This paper reviews the SciTS landscape and theories of transdisciplinarity. It also provides insights about the shifting paradigms currently occurring in the discourse and identifies challenges for translational professionals
Multi-conjugated adaptive optics imaging of distant galaxies -- A comparison of Gemini/GSAOI and VLT/HAWK-I data
Multi-conjugated adaptive optics (MCAO) yield nearly diffraction-limited
images at 2m wavelengths. Currently, GeMS/GSAOI at Gemini South is the
only MCAO facility instrument at an 8m telescope. Using real data and for the
first time, we investigate the gain in depth and S/N when MCAO is employed for
-band observations of distant galaxies. Our analysis is based on the
Frontier Fields cluster MACS J0416.1-2403, observed with GeMS/GSAOI (near
diffraction-limited) and compared against VLT/HAWK-I (natural seeing) data.
Using galaxy number counts, we show that the substantially increased thermal
background and lower optical throughput of the MCAO unit are fully compensated
for by the wavefront correction, because the galaxy images can be measured in
smaller apertures with less sky noise. We also performed a direct comparison of
the signal-to-noise ratios (S/N) of sources detected in both data sets. For
objects with intrinsic angular sizes corresponding to half the HAWK-I image
seeing, the gain in S/N is 40 per cent. Even smaller objects experience a boost
in S/N by a up to a factor of 2.5 despite our suboptimal natural guide star
configuration. The depth of the near diffraction limited images is more
difficult to quantify than that of seeing limited images, due to a strong
dependence on the intrinsic source profiles. Our results emphasize the
importance of cooled MCAO systems for -band observations with
future, extremely large telescopes.Comment: 7 pages, 7 figures. Accepted for publication in MNRA
