title: Data for: Simulated optical molasses cooling of trapped antihydrogen

description: &lt;p&gt;This data is for a paper where we theoretically and computationally investigate the cooling of antihydrogen using optical molasses cooling. This updates the results in Ref. [1] (P.H. Donnan et al, J. Phys. B &lt;strong&gt;46&lt;/strong&gt;, 025302 (2013)) to the current capabilities of the ALPHA experiment. Through Monte Carlo simulation, we show that the antihydrogen atoms do not give the standard cooling even in an ideal optical molasses because of their small mass and large transition frequency. For optical molasses cooling in the ALPHA trap, the photons are constrained to travel in one direction only. It is only through the phase space mixing in the trap that cooling in all directions can be achieved. We explore the nontrivial role that laser intensity plays in the cooling. We also investigate the possibility for simultaneously cooling atoms in either of the trapped ground states.&lt;/p&gt;

title: Inter-nesting area use, migratory routes, and foraging grounds for hawksbill turtles (Eretmochelys imbricata) in the Western Caribbean

description: &lt;p&gt;The dataset provides tracking and habitat utilization data for hawksbill turtles (&lt;em&gt;Eretmochelys imbricata&lt;/em&gt;) in the Western Caribbean. These data were collected through satellite telemetry, with transmitters deployed on 15 nesting turtles at four key sites: Honduras, Costa Rica, and Panama, between 2000 and 2021.&lt;/p&gt;

&lt;h3&gt;Context:&lt;/h3&gt;

&lt;p&gt;Hawksbill turtles are critically endangered due to habitat loss, bycatch, and illegal harvesting. The dataset aims to fill knowledge gaps on their inter-nesting, migratory, and foraging behaviors, essential for developing effective conservation strategies.&lt;/p&gt;

&lt;h3&gt;Data Collection Methods:&lt;/h3&gt;

&lt;p&gt;Satellite transmitters were attached to nesting females, and their movements were monitored to record location, direction, and habitat utilization. The data were processed using advanced statistical and geospatial tools to estimate core habitat areas and migration corridors.&lt;/p&gt;

&lt;h3&gt;Objective:&lt;/h3&gt;

&lt;p&gt;The primary objective of the dataset is to identify critical habitats (e.g., inter-nesting areas, foraging grounds), migration routes, and the influence of ocean currents on turtle movement. This information supports the development of conservation plans to mitigate threats and promote population recovery.&lt;/p&gt;

&lt;h3&gt;Research Question:&lt;/h3&gt;

&lt;ul&gt;
 &lt;li&gt;How do hawksbill turtles utilize inter-nesting, migratory, and foraging habitats in the Western Caribbean?&lt;/li&gt;
 &lt;li&gt;What are the spatial and temporal patterns of their movements?&lt;/li&gt;
 &lt;li&gt;How can this information inform multinational conservation efforts?&lt;/li&gt;
&lt;/ul&gt;
description: The study tracks 15 hawksbill turtles in the Western Caribbean, revealing inter-nesting, migration, and foraging patterns. Key findings highlight vital habitats like the Nicaragua Rise and stress the need for multinational conservation efforts to protect.

title: Lindenwood Nature Preserve Plant Survey

description: &lt;p&gt;We established 30 plot locations within Lindenwood Nature Preserve. Within a 5x5 m plot centered on the plot location, we randomly located two 1 m&sup2; quadrats. Within each quadrat, we identified and counted each understory plant (&lt;u&gt;&lt;&lt;/u&gt; 1 m height). Within a 10x10 m plot centered on the plot location, we counted and identified midstory plant (&gt; 1 m height, &lt; 8 cm diameter at breast height [dbh, 1.37 m above soil surface]). We collected each newly encountered understory and midstory species and deposited the voucher in the Purdue University Fort Wayne Department of Biological Sciences herbarium. Within a 15x15 m plot centered on the plot location, we counted, identified, and measured dbh for all overstory plants. At the plot center and all plot corners, we measured litter depth and percent canopy cover (concave spherical densiometer).&lt;/p&gt;

&lt;p&gt;Data includes understory, midstory, and overstory plant data; environmental data (litter depth and canopy cover); and voucher list for survey project at Lindenwood Nature Preserve, City of Fort Wayne Parks and Recreation, Allen County, Indiana.&lt;/p&gt;

&lt;p&gt;Project conducted under Indiana Department of Natural Resources Division of Nature Preserves Scientific Research/Collecting Permit NP24-73.&lt;/p&gt;

title: Changes of soil water content and lateral flow exert large effects on soil thermal dynamics across Alaskan landscapes

description: &lt;p&gt;Both lateral surface and subsurface hydrological processes affect soil moisture dynamics, yet most land surface models (LSMs) only solve subsurface water movement vertically.  Here we use a 3-D ecosystem model (ECO3D; Liao et al., 2019) that considers both land surface and subsurface hydrologic processes to simulate soil moisture, which is then used to drive a 1-D vertical soil thermal model (TEM-STM; Zhuang et al., 2002) to simulate the soil moisture effects on soil thermal dynamics in central Alaska.  Our coupled model improves soil temperature estimates by 43.5% in comparison with observational data.  Soil moisture has little effect on soil temperature during the wet season (-1.5 %) and a substantial influence during the dry season (60%).  Spatially, water lateral flow has significant impacts on both soil moisture and soil temperature, causing model estimates for unfrozen/thawed areas in the transition season to increase by ~10% in the study area. Our results highlight the importance of considering dynamic soil moisture, as well as lateral flow effects, on soil thermal dynamics in permafrost regions.&lt;/p&gt;

title: Planning and Dynamic Management of Autonomous Modular Mobility Services

description: &lt;p&gt;This project aimed to address the challenges faced by on-demand mobility operators in understanding and addressing spatiotemporal random bipartite matching problems (ST-RBMPs). At the planning level, we developed analytical models to estimate the expected system performance in a static RBMP. At the operational level, we designed solution algorithms to improve the overall service efficiency in ST-RBMPs with different types of supply arrivals. Although our main focus was on the application of on-demand mobility services, these models can also be applied to other contexts such as resource allocation, target detection, etc. This project aimed to address the following research objectives:&lt;/p&gt;

&lt;p&gt;1. Propose an analytical model with closed-form formulas (without statistical curve fitting) that estimate the expectation of the optimal matching distance for static RBMP, where the bipartite vertices are distributed randomly over a discrete network. These formulas can be incorporated into queuing and optimization models to identify the best operational strategies in on-demand mobility systems with closed- or open-loop resource arrivals. It helps determine the optimal decision timing for whether newly arriving customers should be matched instantly or pooled into a batch for matching.&lt;/p&gt;

&lt;p&gt;2. For ST-RBMPs with closed-loop resources, where arriving customers shall be matched instantly, the objective is to propose a Pareto-improving strategy that allows matched vertices to be swapped among candidates with improved matching distances as the system evolves. This strategy could enhance system efficiency by reducing the overall expected matching distance and mitigating the so-called Wild Goose Chasing (WGC) phenomenon. Approximate analytic formulas can be derived from a series of differential equations and spatial probability models to estimate the expected system performance in the steady state.&lt;/p&gt;

title: Smart Construction Work-Zone Safety with V2I Passive Material Sensing

description: &lt;p&gt;This study explored new vehicle to infrastructure (V2I) technology in construction work zones (CWZ), where speeding, unsafe driving behaviors, and drivers&#39; failure to obey traffic signs contribute significantly to elevated accident rates and fatalities. The objective of this research to advance CWZ safety by evaluating the potential of 3-axis magnetometers attached to a moving cart and traversing over a pavement-assisted passive sensing system can improve vehicle lateral positioning and warning in CWZ. Secondly, to develop a process to implement a programmable ferromagnetic oxide material for roadway coatings to interface with vehicles containing magnetometers on a field site. The research testing used a custom-built cart equipped with multiple 3-axis magnetometer to detect EM signals from invisible markings composed of 10% and 20% CrO₂, that were created to alert for speed, lane merges, and lane-keeping. The invisible marking strips were oriented and positioned in various ways to test the repeatability and ability to reliable detect a signal and signature that could be interpreted with automated algorithm. The experimental test results were acquired in a parking and signal-processing technique was established that normalized the raw signals, removed background EM signals not related to the created EM signatures, filtered high- and low-frequency noise, and took the derivative of the EM flux density with respect to the number of points. The V2I signals in the Y and Z-axes occasionally failed to exceed the minimum threshold set for the experiments, but the X-axis signals consistently exceeded the minimum value of &plusmn;200nT throughout the testing. The minimum threshold signals were used to calculate the speed of the cart, indicate a lane merge, and determine the lateral lane position of the cart. The detected speed signals closely correlated with the GPS speed measurements on the cart as well as provided accurate cart positioning and maneuvering actions. This pilot study demonstrated the potential of V2I communication specifically EM pavement signatures to enhance CWZ safety and provide detectable and actionable feedback to the vehicle.&lt;/p&gt;

title: Data for: Whole genome resequencing data provide high-resolution conservation insights into population structure resulting from natal philopatry

description: lt;p align=quot;leftquot;gt;This is the associated data for the manuscript amp;quot;Whole genome resequencing data provide high-resolution conservation insights into population structure resulting from natal philopatry.amp;quot; Whole genome resequencing can be a powerful tool for uncovering biological insights and quantifying population genomic metrics that are relevant to conservation. These biological and conservation insights have the potential to be most profound in secretive or elusive species that are understudied but may be waning. The western chicken turtle (lt;emgt;Deirochelys reticularia miaralt;/emgt;) is one such example where conservationists are concerned about reported population declines. Here, we report results from analyses of genome sequence data from western chicken turtles and how the associated inferences could be used to inform management decisions. We first sequenced and assembled a novel reference genome, then conducted a population genomics resequencing survey across much of Texas that represents one of the first in any freshwater turtle. We uncovered remarkably fine-scale population structure indicative of extensive natal philopatry. Absolute values of fixation indices were small, but principal component analyses of the resequencing data readily separated individuals into clusters that correspond to their geographic sampling site (i.e., wetland) and phylogenomic analyses revealed monophyletic groupings that also correspond to wetlands. Estimates of individual genome-wide heterozygosity (lt;emgt;Hlt;/emgt;) were similar to those observed for threatened or endangered turtle species. Collectively, our data indicate that western chicken turtle populations have limited genomic diversity that is spatially differentiated due to natal philopatry and limited gene flow. We discuss the relevance of these insights as they pertain to turtle biology, including the conservation implications of philopatry in a potentially declining species. The dataset published here includes metadata for each of the sequenced individuals in this study, including information on age, sex, and sampling location.lt;/pgt;

title: Image Data and Analysis Materials for In-situ Fracture Mechanics Experiments on Human Cortical Bone Treated Ex-vivo with Raloxifene

description: &lt;p&gt;This publication documents 3D image stacks  for two in-situ loaded fracture mechanics specimens observed with 3D X-ray microscopy, 2D image stacks of the crack mouth opening displacement during said loading, and analysis codes which supported the publication.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Materials&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The diaphysis of a human (75-year-old, male) cadaveric femur was obtained through the Indiana University School of Medicine Anatomical Donation Program. Nominal 4 mm x 4 mm x 24 mm beams were sectioned from the femur diaphysis. Experiments were conducted on 12 beams. Beams were assigned to 2 groups: treated with Raloxifene (RAL), treated with a vehicle (VEH) control. Image data are provided for one beam from the RAL group and one beam from the VEH group. Additional images can be made available upon request to the corresponding author. &lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Imaging&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;For in-situ fracture mechanics experiments:&lt;/p&gt;

&lt;p&gt;2D and 3D scans were acquired by Glynn Gallaway using a 4-point bending rig for single edged notched bend specimens in a water bath with a Deben CT5000N load cell (Deben, Bury St. Edmunds, UK) in a Zeiss XRADIA 510 Versa 3D X-Ray microscope (Carl Zeiss AG, Baden-W&uuml;rttemberg, Germany) at Purdue University. The 4-point bending frame had a span 16 mm with X-ray transparent, glassy carbon supports. To maintain hydration, bending frame was situated in a waterbath filled with DI water. Displacements were applied at 0.1 mm/min. Load cell outputs were monitored and recorded. During loading 2D images were obtained every 1 second. 3D X-ray images were acquired with a resolution of 4.5 um, exposure time 6 sec., 2401 projections, 120 kV, 10 W, 4 x objective, and a LE2 filter. X-ray projections were processed through XRADIA Scout-and-Scan Reconstructor. A recursive Gaussian smoothing filter (s=1 pixel) was applied to reduce image artifacts. Image stacks are exported as tiff files and provided for each specimen. Images are provided for one RAL treated sample and one VEH treated sample.&lt;/p&gt;
