title: The LOFAR Two-metre Sky Survey (LoTSS) V. Second data release (P174+62)

description: In this data release from the ongoing LOw-Frequency ARray (LOFAR) Two-metre Sky Survey (LoTSS) we present 120-168 MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at approximately 12h45m +44◦30′ and 1h00m +28◦ 00′ and spanning 4178 and 1457 square degrees respectively. The images were derived from 3,451 hrs (7.6 PB) of LOFAR High Band Antenna data which were corrected for the direction-independent instrumental properties as well as direction-dependent ionospheric distortions during extensive, but fully automated, data processing. A catalogue of 4,396,228 radio sources is derived from our total intensity (Stokes I) maps, where the majority of these have never been detected at radio wavelengths before. At 6′′ resolution, our full bandwidth Stokes I continuum maps with a central frequency of 144 MHz have: a median rms sensitivity of 83 μ Jy/beam; a flux density scale accuracy of approximately 10%; an astrometric accuracy of 0.2′′; and we estimate the point-source completeness to be 90% at a peak brightness of 0.8 mJy/beam. By creating three 16 MHz bandwidth images across the band we are able to measure the in-band spectral index of many sources, albeit with an error on the derived spectral index of &gt; ±0.2 which is a consequence of our flux-density scale accuracy and small fractional bandwidth. Our circular polarisation (Stokes V) 20′′ resolution 120-168 MHz continuum images have a median rms sensitivity of 95 μ Jy/beam, and we estimate a Stokes I to Stokes V leakage of 0.056%. Our linear polarisation (Stokes Q and Stokes U) image cubes consist of 480 97.6 kHz wide planes and have a median rms sensitivity per plane of 10.8mJy/beam at 4′ and 2.2mJy/beam at 20′′; we estimate the Stokes I to Stokes Q/U leakage to be approximately 0.2%. Here we characterise and publicly release our Stokes I, Q, U and V images in addition to the calibrated uv-data to facilitate the thorough scientific exploitation of this unique dataset. This is field P174+62.

title: Effectiveness of Softening Agents for Enhancing Properties of Asphalt Mixes with High RAP Contents

description: A high percentage of reclaimed asphalt pavement (RAP) in new asphalt concrete can lead to developing premature failure of asphalt pavements due to fatigue or low-temperature cracking. The use of softening agents in asphalt binders can resolve these problems. The aim of this study is to evaluate the effectiveness of softening agents for enhancing the properties of asphalt mixes with high RAP contents. Two waste products, namely, waste cooking oil (WCO), and engine bottom oil (EBO) along with a commercially produced rejuvenator were investigated in this study. The following three types of Performance Grade (PG) binders, each collected from two different sources, were considered in this study: PG 64-22, PG 70-22, and PG 76-22. These PG binders blended with different amounts (0, 15, 25, 40, and 60%) of RAP binders were rejuvenated with different dosages (0, 10, 15, and 20%) of the selected softening agents. Empirical tests (e.g., penetration and pH), Superpave tests, Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and limited laboratory and field performance of asphalt mixture samples were also evaluated. It was found that the rejuvenators reduced the viscosity of the binder samples. The results showed that the rejuvenated binders reduce the production temperatures as well as the brittleness of the hard binders. The AFM results showed that modulus and deformation values of rejuvenated binders were significantly less than those of their unrejuvenated counterparts. Similarly, distinct peaks were observed in the FTIR peaks due to the rejuvenation. The findings of this study will help pavement professionals in selecting suitable rejuvenators in the construction of pavements with high RAP contents.

title: Directional ballistic transport in the two-dimensional metal PdCoO2

description: In an idealized infinite crystal, the material properties are constrained by the symmetries of its unit cell. However, the point-group symmetry is broken by the sample shape of any finite crystal, but this is commonly unobservable in macroscopic metals. To sense the shape-induced symmetry lowering in such metals, long-lived bulk states originating from an anisotropic Fermi surface are needed. Here we show how a strongly facetted Fermi surface and the long quasiparticle mean free path present in microstructures of PdCoO<sub>2</sub> yield an in-plane resistivity anisotropy that is forbidden by symmetry on an infinite hexagonal lattice. We fabricate bar-shaped transport devices narrower than the mean free path from single crystals using focused ion beam milling, such that the ballistic charge carriers at low temperatures frequently collide with both of the side walls that define the channel. Two symmetry-forbidden transport signatures appear: the in-plane resistivity anisotropy exceeds a factor of 2, and a transverse voltage appears in zero magnetic field. Using ballistic Monte Carlo simulations and a numerical solution of the Boltzmann equation, we robustly identify the orientation of the narrow channel as the source of symmetry breaking.

title: Sawgrass above ground biomass from the Shark River Slough, Everglades National Park (FCE LTER), South Florida, USA, November 2000 - ongoing

description: Sawgrass biomass is measured for TS/Ph-1, 2, 3, & 6 since 1999; TS/Ph-4 & 5 since 1997 to 2006; SRS-1b, 2, & 3 since 2000; SRS1c for 2005 to 2006, and SRS1d since 2006. Three 1 m2 plots are placed on each site. The sites are measured every two months. The number of sawgrass plants is counted for each 1 m2 plot and one third or a minimum of fifteen plants is measured. For each measured plant, measurements of the total number of live leaves, length of the live leaves, and culm diameter at the base are taken. From these measurements we calculate the average leaf length, and the sum of the length of the leaves. We created a model for biomass using a stepwise regression to see which of the variables measured and calculated are more correlated to explain plant biomass. Obtaining the mean biomass for the plants within the plot and multiplying it by the number of plants counted in the plot calculates biomass for each plot. The total biomass for each plot is summed with the other two plots in the same site, and they are averaged to obtain one biomass number per site. To validate our model, plant clippings are obtained in which four plants are clipped (small, medium, large, inflorescence) from each site. The same measurements are applied to the clipped plants as those applied to the measured plants in the plots. The plant clippings are oven dried at 70 degrees C and weighed.

title: Feasibility Assessment of Warm Mix Asphalt in Arkansas

description: The future of Warm Mix Asphalt (WMA) technologies is promising in the U.S. However, the Arkansas Department of<br> Transportation (ARDOT) does not have any specific guidelines to implement them in the field. This research aims to<br> provide necessary baseline data for WMA as a proof of concept. In this study, three ARDOT approved Performance<br> Grade (PG) binders namely PG 64-22, PG 70-22, and PG 76-22 were investigated. Each of these binders was obtained<br> from two different sources. They were modified by varying doses of four selected additives: Sasobit®, Advera®,<br> Evotherm®, and Rediset®. Additionally, four different types of aggregates (sandstone, limestone, gravel, and dolomite)<br> from different quarries in Arkansas were evaluated for their compatibility with modified binders. Empirical test<br> (Penetration test), Superpave Performance tests such as Rotational Viscometer, Rolling Thin-Film Oven (RTFO),<br> Pressure-Aging Vessel (PAV), Dynamic Shear Rheometer (DSR), and Bending Beam Rheometer), PG Plus tests such as<br> Multiple Stress Creep Recovery and Frequency Sweep, chemical analyses (SARA analysis, FTIR, pH), science-based<br> test (Surface Free Energy), and Texas Boiling Test on loose mixture samples were conducted at different aging<br> conditions. Based on the RV test results, reduced mixing and compaction temperatures have been observed for Sasobit®,<br> Evotherm®, and Rediset® modified samples. The DSR test results suggest that both Sasobit® and Advera® can reduce rut<br> potential. On the other hand, BBR test results indicate that both Evotherm® and Rediset® have the capabilities of<br> improved resistances against fatigue and low-temperature thermal cracking. Binder samples modified by these have also<br> demonstrated minimal stripping in SFE and Texas Boiling Test. Advera® has modified the chemical compositions of the<br> neat binders, which was also observed in the SARA analysis. The findings of this study will help the agency to select the<br> most appropriate WMA additive along with its application rate.

title: Development of Cost-Effective High-Modulus Asphalt 5. Report Date Aug. 2021 Concrete (HMAC) Mixtures Using Crumb Rubber and Local Construction Materials in Louisiana

description: One of the emerging solutions to enhance the durability of asphalt pavements is the use of a French asphalt mix<br> known as “High-Modulus Asphalt Concrete (HMAC).” This mix uses a hard asphalt binder, high binder content<br> (about 6%), and low air voids content as compared to Superpave mixtures. The key objective of this study was<br> to develop a cost-effective HMAC mixture using crumb rubber and local materials in Louisiana. To achieve this<br> objective, four HMAC mixtures were prepared using two asphalt binders (PG 82-22 and PG 76-22 plus 10%<br> crumb rubber) and two Reclaimed Asphalt Pavement (RAP) contents (20% and 40%); additionally, a<br> conventional Superpave mixture in Louisiana was prepared as a control mixture. The laboratory performance<br> of these five mixtures was evaluated in terms of workability, dynamic modulus, rutting resistance, and cracking<br> resistance. The AASHTOWare Pavement ME Design software was also used to estimate the long-term field<br> performance of these mixtures. Results indicated that the HMAC mixture prepared with 10% crumb rubber and<br> 20% RAP successfully met the French mix design specifications for HMAC and LaDOTD specifications. This<br> HMAC mix outperformed the control Superpave mix in terms of dynamic modulus, rutting resistance, and<br> cracking resistance. Additionally, this HMAC mixture can reduce the required asphalt thickness by 1.5 or 2<br> inches based on traffic level. The cost-effectiveness analysis indicated that this HMAC mixture was more costeffective<br> than conventional Superpave mixtures in Louisiana. In addition, this mixture is environmentallyfriendly<br> since it can reduce the disposal of scrap tires in landfills.
