2013 Poster Session, Geospatial Modeling of Mountain Pine Beetle Mortality by...
Mountain pine beetle (Dendroctonus ponderosae) has infested 3.4 million acres of forest in Colorado since 1996 and continues to spread throughout the forests of western North America. This project identified the severity and extent of lodgepole pine (Pinus contorta) tree mortality at Fraser Experimental Forest (FEF). We mapped the spatial extent and severity of the outbreak using the Software for Assisted Habitat Modeling (SAHM) and a boosted regression tree model. The model combined satellite imagery from the Landsat 5 TM sensor, a variety of spectral vegetation indices, differenced satellite images (pre- and post-infestation), and field data collected at FEF. The results yielded a continuous mortality map showing the ratio of dead lodgepole pine to the basal area of all trees. The model accuracy was tested in R and had a cross validation (CV) correlation of 0.782 and an adjusted r-squared of 0.8072. The methodology from this project can be scaled up to assess mountain pine beetle impacts at a regional level. Results from this study will be used to enhance forest management efforts in mitigating hazards from standing dead trees and will provide a foundation for further research into the impacts of mountain pine beetle on wildlife habitat, hydrology, and recreation.

The document summarizes research from the Terrestrial Ecosystem Research Network (TERN) on gaps in long-term ecological studies across Australian environments. TERN analyzed data from long-term studies against climate zones, vegetation groups, biomes, and management regions. Results showed that arid and semi-arid areas are poorly monitored, while spinifex grasslands, acacia woodlands, and chenopod shrublands have little data. However, TERN infrastructure and standardized national sampling methods like Ausplots will help fill these gaps over time by automatically uploading new ecological data.
AusPlots
The AusPlots Facility aims to establish a national network of biodiversity monitoring plots across Australian ecosystems to collect baseline ecological data. Over 1,000 permanent plots will be located in the rangelands and forests using a stratified sampling approach based on bioregional groupings. Standardized surveys of vegetation and soils will be conducted at each plot to increase understanding of species distributions, threats, and carbon/nutrient cycles while also validating remote sensing. Engagement with state agencies and the broader ecological community is emphasized to integrate monitoring efforts and disseminate findings.

Holistic grazing management is studied and compared to traditional grazing. Animal health, vegetation, and wildlife are examined on plots practicing holistic grazing. Methods include measuring milk yield and growth rates in animals, analyzing vegetation transects, using camera traps and GPS data to understand land usage. Preliminary results show higher milk yields and animal growth rates for those grazing inside holistically managed areas. Future work includes further analyzing animal health measures, production cage data, and camera trap photos.
Discovery Day Mertes
This study examined how three East African bird species—Von der Decken's hornbill, fork-tailed drongo, and Kori bustard—respond to environmental conditions at different spatial scales ranging from 10m to 1000m. The researchers found that at large scales, drongos were associated with variable shrub density and proximity to roads, hornbills were restricted to certain land cover classes, and bustards selected areas with restricted elevations and soil types. At small scales, drongos selected areas with low shrub density and variable terrain and roads, hornbills preferred complex vegetation and dense shrubs, and bustards were found in areas with variable shrub density and soil types. Species responses were consistent

Camel milk production is growing in importance, but little is known about camel health and disease. The document discusses monitoring camel health by studying mastitis, an udder infection that impacts milk production. Researchers will survey herders about milking practices and veterinary access. They will also collect milk samples to culture any mastitis-causing bacteria and examine milk container cleanliness to identify risks and make recommendations for improving camel health, milk safety, and production.
Discovery Day Unks
This document summarizes Ryan Unks' research on linking pastoralism and landscape ecology in Laikipia County, Kenya. It discusses how pastoralist herding practices have changed over time due to loss of land and influences of the market. Vegetation across the landscape has also changed, with increases in unpalatable species and decreases in species important for pastoralists. The research aims to understand how social and institutional factors influence grazing practices and spatial relationships between plant communities and grazing. The goal is to explore implications of interrelated social and ecological changes for livelihoods and natural resource management. Methods include interviews, surveys, satellite image analysis, and plant community analysis.

This document provides information about lion conservation efforts in Kenya. It discusses how the lion population in Kenya has declined to fewer than 2,000 lions, due mostly to small parks without buffers, bushmeat poaching, and conflicts with livestock. The Laikipia Predator Project has worked since 1997 with Kenyan authorities, ranchers, and communities to develop coexistence strategies between people, livestock, and predators in Laikipia. Through their efforts, they have restored the lion population to 250 lions while reducing livestock depredation rates from 50% to as low as 0%. Their work conserving lions through non-lethal measures has benefited the local economy through tourism, which employs over 1,300 people.

Termite mounds can help prevent desertification by creating fertile islands of vegetation. Termites in Laikipia improve the soil nutrients and water infiltration on their mounds, allowing vegetation to thrive even with decreasing rainfall. Studies show that areas with termite mounds maintain higher biomass during periods of low rainfall compared to areas without mounds.
Discovery Day Wayland
Ecohydrology is the study of how the landscape and water cycle interact. The document discusses how drought affects local plants like the Acacia mellifera tree. It provides facts about the A. mellifera, including that its leaves are high in protein and its gums are used in food additives. Rainfall data from 2013 to 2014 is presented, showing lower rainfall in 2014, and it questions what happens to A. mellifera during periods of low rainfall.

1) There are two types of zebra societies - plains zebras and mountain zebras which have closed membership, while Grevy's zebras and Asian wild asses have open membership. This matters because wandering males in open societies don't protect females and young, putting them more at risk of lion predation.
2) Grevy's zebras don't like black cotton soil, which can lead to poor performance in hybrids.
3) Some Laikipia zebra populations are declining, with actual populations lower than theoretical populations, indicating new approaches are needed to balance protecting at-risk species.

With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

THEMATIC APPERCEPTION TEST(TAT) cognitive abilities, creativity, and critic...Abdul Wali Khan University Mardan,kP,Pakistan
hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsAuthoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
