Figure 7. Grades 19 and 24 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 7. Grades 19 and 24. The Xiphosura have paired book gills under the opisthosoma (thoracetron). Although the group has a long fossil record, there are only 4 living species (Lamsdell 2020). Scorpions, with paired book lungs, chelicerate pedipalps, and an unusual appendage at the rear of the opisthosoma, are now diverse and successful.
Figure 6. Grades 16 and 17 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 6. Grades 16 and 17. The Onychophora, or velvet worms, are successful predators with many species in terrestrial, mostly tropical habitats. With flexible legs, they resemble giant tardigrades. The Mandibulata is by far the most successful group of animals, including the myrapods and the pancrustaceans; the latter group includes the insects and a diverse array of crustaceans, mostly marine.
Figure 5. Grades 12 and 15 in A deeper phylogeny of jumping spiders (Araneae: Salticidae)
Figure 5. Grades 12 and 15. The Ecdysozoa links nematodes, nematomorphs and arthropods to a common ancestor with the ability to shed a protective trilaminate cuticle as it grew. With panarthropods like this minute, aquatic tardigrade, we see the appearance of paired, segmental appendages.

Research Incentive Programs for Closures of Public and Private Grade Crossings
<p>Corresponding data set for Tran-SET Project No. 17PPLSU13. Abstract of the final report is stated below for reference:</p> <p>"Vehicle-train crashes that occur at highway-rail crossings result in injuries, fatalities, and damage to equipment. In order to reduce the number of vehicle-train crashes, Federal Railroad Administration requires states which have challenges with crossing safety, including Louisiana, to develop a State Action Plan to improve grade crossing safety. Consequently, identification of specific solutions for improving safety at crossings was included in the 2015 Louisiana Transportation Plan as one of its objectives. This study seeks to identify and evaluate current and new incentive programs that encourage closure of at-grade railroad crossings to reduce the number of potential vehicle-train collision points, and hence improve safety. To accomplish this, a survey was designed and was distributed to personnel of state and railroad agencies. Survey responses from the DOTs revealed that currently, 16 states had no incentive programs for consolidation or closure of highway-rail crossings. Analysis of the survey data revealed that states without any incentive program had the least proportion of highway-rail crossing closures. The study revealed that cash incentives, while popular are not effective because although the Federal Government contributes to a state’s effort in offering cash incentives for closure of public grade crossings, the amount is not substantial enough to be considered a significant incentive by most local governments. Also, track relocation, while effective is mostly impractical due to the high costs involved. A literature review revealed that having a mathematical model to guide on the selection of crossings for consolidation or closure provides sound scientific basis and are usually welcomed by the community. The research team identified three potential new incentives that could work well for Louisiana namely crime rate reduction incentives, greenness improvement programs, and the development of a grade crossing consolidation model that considers safety, among a plethora of other factors, to be used to prioritize crossings to be closed. However, additional work is required to validate these programs for statewide deployment."</p>

Synthetic post-dive precordial and subclavian Doppler ultrasound using Kisman-Masurel and Spencer grades
<p><span>Doppler ultrasound (DU) measurements are used to detect and evaluate venous gas emboli (VGE) formed after decompression. Automated analysis methodologies of these VGE have been developed on varying real-world datasets of limited size and without ground truth values preventing objective evaluation. We develop and report a method to generate synthetic post-dive data using DU signals collected in both precordium and subclavian vein with varying degrees of bubbling matching field-standard grading metrics. This method is adaptable, modifiable, and reproducible, allowing for researchers to tune the produced dataset for their desired purpose. We provide the baseline Doppler recordings and code required to generate synthetic data for researchers to reproduce our work and improve upon it. We also provide a set of pre-made synthetic post-dive DU data spanning six scenarios representing the Spencer and Kisman-Masurel (KM) grading scales as well as precordial and subclavian DU recordings. By providing a method for synthetic post-dive DU data generation, we aim to improve and accelerate the development of signal processing techniques for VGE analysis in Doppler ultrasound. </span></p>

A New Generation of Dense-Graded Asphalt Mixtures with Superior Performance against Stripping and Moisture Damage
<p>The presence of moisture beneath the pavement surface is a matter of great concerns as it is responsible for significant distresses such as asphalt concrete (AC) stripping, fatigue cracking, rutting, and poor durability of asphalt mixes. The objective of this study was to evaluate and recommend an asphalt mixture design that would provide superior performance against AC stripping and cracking. To achieve this objective, a laboratory test factorial was developed to evaluate the use of nanomaterials, emerging anti-stripping agents, warm-mix asphalt technologies, and adhesion promotors. In the experimental program, the modified Lottman test (AASHTO T 283) and the Indirect Tensile Asphalt Cracking Test (IDEAL-CT) test were used as performance indicators of moisture damage resistance and cracking susceptibility. Results were analyzed statistically to identify and quantify the effects of the design variables and selected additives on the performance, moisture damage resistance, and durability of asphalt mixes. Based on the cracking test results, a superior cracking resistance performance was observed with Zycotherm<sup>®</sup>, irrespective of the mix type. AD-here<sup>®</sup> had the lowest average cracking indices for both mix types, which suggests that it would not function as good as the other additives in terms of cracking resistance. Overall, Stone Matrix Asphalt (SMA) mixes showed greater cracking resistance than the dense-graded mixture, which may have been a result of the RAP material used in the dense-graded mix and its lower asphalt binder content. In terms of moisture resistance, both nanomaterials (Graphene Nanoplatelet [GNP] and Nanoclay) did not perform well as they did not meet the minimum required tensile strength ratio (TSR) criterion. Overall, nanomaterials showed the lowest TSR values in both mix types suggesting that their effectiveness against moisture-induced damage may not be as good as warm-mix additives. In addition, warm-mix additives were expected to show enhanced performance in terms of moisture resistance as compared to the other additives evaluated in this study.</p>
Patchy particle insights into self-assembly of transparent, graded index squid lenses
<p>Squids have spherical, gradient index lenses that maximize optical sensitivity while minimizing light scattering and geometric aberration. Previous studies have shown that the constituent lens proteins behave like patchy particles, and that a density gradient of packing fraction $\sim 0.01$ to $1$ assembles from a gradient of average particle valence, $\langle M\rangle$ $\approx 2.1$ to $\langle M\rangle$ $>6$. A priori, transparency requires that all regions within the larger gradient must minimize density fluctuations at length scales close to the wavelength of visible light. It is not known how a material can achieve this at all possible packing fractions via attractive interactions. We also observe that the set of proteins making the lens is remarkably polydisperse (there are around 40 isoforms expressed). Why does nature employ so many geometrically similar isoforms when theory suggests a few would suffice, and what, if any, is the physical role of the polydispersity? This study focuses on answering these questions for the sparsest regions of the lens, where the patchy nature of the system will have the largest influence on the final structure. We first simulated mixtures of bi- and trivalent patchy particles and found a strong influence of patch angle on the percolation and gel structure of the system. We then investigated the influence of the interaction polydispersity on the structure of the $M=2.1$ system. We find that increasing the variance in patch energies and single-patch angle appears decrease the length scale of density fluctuations while also moving the percolation line to lower temperature. S-crystallin geometry and polydispersity appear to contribute to promoting regular percolation of a gel structure while also limiting density fluctuations to small length scales, thereby promoting transparency in the annealed structure.</p>
A geopositioned, evidence-graded, pan-species compendium of Mayaro Virus occurrence
<div> <div> <p>Mayaro Virus (MAYV) is an emerging health threat in the Americas that can cause febrile illness as well as debilitating arthralgia or arthritis. To better understand the geographic distribution of MAYV risk, we developed a georeferenced database of MAYV occurrence based on peer-reviewed literature and unpublished reports. Here we present this compendium, which includes both point and polygon locations linked to occurrence data documented from its discovery in 1954 until 2022. In the associated data descriptor manuscript (<a href="https://doi.org/10.1101/2023.03.07.23286930">https://doi.org/10.1101/2023.03.07.23286930</a>), we describe all methods used to develop the database including data collection, georeferencing, management, and quality-control. We also describe a customized grading system used to assess the quality of each study included in our review. The result is a comprehensive, evidence-graded database of confirmed MAYV occurrence in humans, non-human animals, and arthropods to-date, containing 262 geo-positioned occurrences in total. This database – which can be updated over time – may be useful for local spill-over risk assessment, epidemiological modelling to understand key transmission dynamics and drivers of MAYV spread, as well as identification of major surveillance gaps.</p> </div> </div>
