Sustainability and transparency in computational cognitive neuroscience
In this talk, I will discuss open science practices that aim to foster sustainability and transparency in computational cognitive neuroscience. First, I will review recent community efforts that aim to ease data sharing and analytical reproducibility, such as the reports of the OHBM Committees on Best Practice in Data Analysis and Sharing (COBIDAS) and the Brain Imaging Data Structures (BIDS). Second, I will discuss neuroimaging data sharing strategies in the light of ethical and legal constraints, such as the European General Data Protection Regulation (GDPR). Finally, I will discuss some common-sense guidelines for day-to-day research practice that aim to maximize the societal impact of computational cognitive neuroscience
Light Scattering in Transparent Glass Ceramics
Transparent glass ceramic materials, with microstructures comprised of
dispersed nanocrystallites in a residual glass matrix, offer the prospect of
nonlinear optical properties. However, good transparency requires low optical
scattering and low atomic absorption. The attenuation of light due to
scattering (turbidity) will depend upon the difference in refractive index of
the two phases and the size and distribution of crystals in the glass. Here, we
model the glass ceramic as a late-stage phase-separated structure, and compute
scattering in this model. We find that the turbidity follows a k^8 R^7
relationship, where k is the wavevector of light in the glass ceramic and R is
the average radius of the crystals in the glass.Comment: 4 pages, 4 figure
Balloon platform for extended-life astronomy research
A configuration has been developed for a long-life balloon platform to carry pointing telescopes weighing as much as 80 pounds (36 kg) to point at selected celestial targets. A platform of this configuration weighs about 375 pounds (170 kg) gross and can be suspended from a high altitude super pressure balloon for a lifetime of several months. The balloon platform contains a solar array and storage batteries for electrical power, up and down link communications equipment, and navigational and attitude control systems for orienting the scientific instrument. A biaxial controller maintains the telescope attitude in response to look-angle data stored in an on-board computer memory which is updated periodically by ground command. Gimbal angles are computed by using location data derived by an on-board navigational receiver

NSDL EduPak: An Open Source Education Repository Solution
4th International Conference on Open RepositoriesThis presentation was part of the session : Conference PostersEducational organizations and institutions focused on establishing specialized digital collections, conducting educational research, or providing students, teachers and instructors with discipline-oriented pedagogical products and tools require basic technology to begin building educational digital repositories. To help meet these needs, the National Science Digital Library (NSDL) has announced the release of NSDL EduPak. Specifically designed for education, NSDL EduPak packages technology for digital storage, access, and workflow into a convenient bundle. This poster reviews three core EduPak components with examples of how they are used by education communities.National Science Foundatio
Growth laws and self-similar growth regimes of coarsening two-dimensional foams: Transition from dry to wet limits
We study the topology and geometry of two dimensional coarsening foams with
arbitrary liquid fraction. To interpolate between the dry limit described by
von Neumann's law, and the wet limit described by Marqusee equation, the
relevant bubble characteristics are the Plateau border radius and a new
variable, the effective number of sides. We propose an equation for the
individual bubble growth rate as the weighted sum of the growth through
bubble-bubble interfaces and through bubble-Plateau borders interfaces. The
resulting prediction is successfully tested, without adjustable parameter,
using extensive bidimensional Potts model simulations. Simulations also show
that a selfsimilar growth regime is observed at any liquid fraction and
determine how the average size growth exponent, side number distribution and
relative size distribution interpolate between the extreme limits. Applications
include concentrated emulsions, grains in polycrystals and other domains with
coarsening driven by curvature

Free-energy landscape of nucleation with an intermediate metastable phase studied using capillarity approximation
Capillarity approximation is used to study the free-energy landscape of
nucleation when an intermediate metastable phase exists. The critical nucleus
that corresponds to the saddle point of the free-energy landscape as well as
the whole free-energy landscape can be studied using this capillarity
approximation, and various scenarios of nucleation and growth can be
elucidated. In this study we consider a model in which a stable solid phase
nucleates within a metastable vapor phase when an intermediate metastable
liquid phase exists. We predict that a composite critical nucleus that consists
of a solid core and a liquid wetting layer as well as pure liquid and pure
solid critical nuclei can exist depending not only on the supersaturation of
the liquid phase relative to that of the vapor phase but also on the wetting
behavior of the liquid surrounding the solid. The existence of liquid critical
nucleus indicates that the phase transformation from metastable vapor to stable
solid occurs via the intermediate metastable liquid phase, which is quite
similar to the scenario of nucleation observed in proteins and colloidal
systems. By studying the minimum-free-energy path on the free-energy landscape,
we can study the evolution of the composition of solid and liquid within nuclei
not limited to the critical nucleus.Comment: 9 pages, 8 figures, Journal of chemical physics to be publishe
The Two States in Plato\u27s Republic
Unlike the state of the Guardians which remains set up as a model in heaven, there is, in Plato\u27s view in the Republic, the faint hope that the state of the Philosopher may be possible
