Laboratory Characterization and Influence of Mineralogy and Grading on the Performance of Treated and Untreated Granular Materials Used as Surface Pavements in Unpaved Road
This paper presents the results of a laboratory study on the influence of grading and granular mineralogy sources (granitic gneiss, basalt and limestone) on the performance of treated and untreated granular materials used as surface pavements in unpaved roads. Results of bearing capacity, resilient modulus and compressive strength tests are discussed. Natural brine, calcium chloride, cement and a polymer emulsion treated samples were tested and compared to untreated samples. The combinations of product, mineralogy and grading showing great performance are finally pointed out
Space biology initiative program definition review. Trade study 6: Space Station Freedom/spacelab modules compatibility
The differences in rack requirements for Spacelab, the Shuttle Orbiter, and the United States (U.S.) laboratory module, European Space Agency (ESA) Columbus module, and the Japanese Experiment Module (JEM) of Space Station Freedom are identified. The feasibility of designing standardized mechanical, structural, electrical, data, video, thermal, and fluid interfaces to allow space flight hardware designed for use in the U.S. laboratory module to be used in other locations is assessed
Space biology initiative program definition review. Trade study 3: Hardware miniaturization versus cost
The optimum hardware miniaturization level with the lowest cost impact for space biology hardware was determined. Space biology hardware and/or components/subassemblies/assemblies which are the most likely candidates for application of miniaturization are to be defined and relative cost impacts of such miniaturization are to be analyzed. A mathematical or statistical analysis method with the capability to support development of parametric cost analysis impacts for levels of production design miniaturization are provided
Space biology initiative program definition review. Trade study 4: Design modularity and commonality
The relative cost impacts (up or down) of developing Space Biology hardware using design modularity and commonality is studied. Recommendations for how the hardware development should be accomplished to meet optimum design modularity requirements for Life Science investigation hardware will be provided. In addition, the relative cost impacts of implementing commonality of hardware for all Space Biology hardware are defined. Cost analysis and supporting recommendations for levels of modularity and commonality are presented. A mathematical or statistical cost analysis method with the capability to support development of production design modularity and commonality impacts to parametric cost analysis is provided
Molecular and Genetic Aspects of Odontogenic Lesions
In this article we outline the molecular findings of select odontogenic tumors. In each section, we briefly review selected the clinicoradiographic, histologic, immunologic features, focusing on the molecular findings and their applications in practice. The understanding of molecular pathobiology at various other organ sites has developed quite rapidly in recent years, however much remains unknown about the genetic profile of odontogenic tumors. Improved understanding of mutations in odontogenic tumors may clarify classification schema and elucidate targets for novel therapies. Molecular testing will no doubt improve our understanding of odontogenic tumor pathogenesis and will likely be, someday, an important component of routine clinical practice and its role will only increase in the coming years
Advances in Atomic Data for Neutron-Capture Elements
Neutron(n)-capture elements (atomic number Z>30), which can be produced in
planetary nebula (PN) progenitor stars via s-process nucleosynthesis, have been
detected in nearly 100 PNe. This demonstrates that nebular spectroscopy is a
potentially powerful tool for studying the production and chemical evolution of
trans-iron elements. However, significant challenges must be addressed before
this goal can be achieved. One of the most substantial hurdles is the lack of
atomic data for n-capture elements, particularly that needed to solve for their
ionization equilibrium (and hence to convert ionic abundances to elemental
abundances). To address this need, we have computed photoionization cross
sections and radiative and dielectronic recombination rate coefficients for the
first six ions of Se and Kr. The calculations were benchmarked against
experimental photoionization cross section measurements. In addition, we
computed charge transfer (CT) rate coefficients for ions of six n-capture
elements. These efforts will enable the accurate determination of nebular Se
and Kr abundances, allowing robust investigations of s-process enrichments in
PNe.Comment: To be published in IAU Symp. 283: Planetary Nebulae, an Eye to the

GUILGET: GUI Layout GEneration with Transformer
Sketching out Graphical User Interface (GUI) layout is part of the pipeline
of designing a GUI and a crucial task for the success of a software
application. Arranging all components inside a GUI layout manually is a
time-consuming task. In order to assist designers, we developed a method named
GUILGET to automatically generate GUI layouts from positional constraints
represented as GUI arrangement graphs (GUI-AGs). The goal is to support the
initial step of GUI design by producing realistic and diverse GUI layouts. The
existing image layout generation techniques often cannot incorporate GUI design
constraints. Thus, GUILGET needs to adapt existing techniques to generate GUI
layouts that obey to constraints specific to GUI designs. GUILGET is based on
transformers in order to capture the semantic in relationships between elements
from GUI-AG. Moreover, the model learns constraints through the minimization of
losses responsible for placing each component inside its parent layout, for not
letting components overlap if they are inside the same parent, and for
component alignment. Our experiments, which are conducted on the CLAY dataset,
reveal that our model has the best understanding of relationships from GUI-AG
and has the best performances in most of evaluation metrics. Therefore, our
work contributes to improved GUI layout generation by proposing a novel method
that effectively accounts for the constraints on GUI elements and paves the
road for a more efficient GUI design pipeline.Comment: 12 pages, 5 figures, Canadian AI Conference 202
