Abstract

This work describes the LLRF and control system in use for a novel accelerator structure developed for a compact design operating in C-band developed by SLAC, with collaboration from RadiaBeam and RadiaSoft. This design is a pulsed RF/pulsed beam system that only provides minimal monitoring for control of each two-cavity pair. Available signals include only a forward and reflected signal for each pair; such a design requires careful consideration of calibration and power-on routines, as well an understanding of how to correct for disturbances caused by the entire RF signal chain, including a new SSA, klystron, and distribution system. An AMD Xilinx RF-SoC with a separate supervisory computer is the LLRF system core, with on-board pulse-to-pulse feedback corrections. This work presents the current status of the project, as well as obstacles and manufacturing plans from the viewpoint of developing for larger-volume manufacturing. This material is based upon work supported by the Defense Advanced Research Projects Agency under Contract Numbers 140D0423C0006 and 140D0423C0007.

Abstract

The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolution of the spectrum we used and the accuracy of wavelength calibration. In this work, radial velocities of LAMOST-II medium resolution (R ~ 7500) spectra are measured for 1,594,956 spectra (each spectrum has two wavebands) through matching with templates. A set of RV standard stars are used to recalibrate the zero point of the measurement, and some reference sets with RVs derived from medium/high-resolution observations are used to evaluate the accuracy of the measurement. Comparing with reference sets, the accuracy of our measurement can get 0.0227 km s/1 with respect to radial velocities standard stars. The intrinsic precision is estimated with the multiple observations of single stars, which can achieve to 1.36 km s/1,1.08 km s/1, 0.91 km s/1 for the spectra at signal-to-noise levels of 10, 20, 50, respectively., Comment: published by ApJs. 13 pages, 13 figures

Abstract

Our study aims to recognize M-type stars which are classified as "UNKNOWN" due to bad quality in Large sky Area Multi-Object fibre Spectroscopic Telescope (LAMOST) DR5 V1. A binary nonlinear hashing algorithm based on Multi-Layer Pseudo Inverse Learning (ML-PIL) is proposed to effectively learn spectral features for the M-type star detection, which can overcome the bad fitting problem of template matching, particularly for low S/N spectra. The key steps and the performance of the search scheme are presented. A positive dataset is obtained by clustering the existing M-type spectra to train the ML-PIL networks. By employing this new method, we find 11,410 M-type spectra out of 642,178 "UNKNOWN" spectra, and provide a supplemental catalogue. Both the supplemental objects and released M-type stars in DR5 V1 are composed a whole M type sample, which will be released in the official DR5 to the public in June 2019, All the M-type stars in the dataset are classified to giants and dwarfs by two suggested separators: 1) color diagram of H versus J~K from 2MASS; 2) line indices CaOH versus CaH1, and the separation is validated with HRD derived from Gaia DR2. The magnetic activities and kinematics of M dwarfs are also provided with the EW of H_alpha emission line and the astrometric data from Gaia DR2 respectively., Comment: 15 pages, 18 figures, accepted by MNRAS

Abstract

We present an empirical stellar spectra library created using spectra from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) DR5. This library represents a uniform data set ranging from 3750 through 8500K in effective temperature (T_eff), from -2.5 through +1.0 dex in metallicity ([Fe/H]), and from 0 to 5.0 dex in gravity (log g). The spectra in the library have resolution R~1800, with well-calibrated fluxes and rest-framed wavelengths. Using a large number of red stars observed by LAMOST, we generated denser K type templates to fill in data missing from current empirical spectral libraries, particularly the late K type. For K giants, we calibrated the spectroscopic surface gravities against the asteroseismic surface gravities. To verify the reliability of the parameters labeled for this library, we performed an internal cross-validation by using a chi^2 minimization method to interpolate parameters of each individual spectrum using the remaining spectra in the library. We obtained precisions of 41 K, 0.11 dex, and 0.05 dex for T_eff, log g, and [Fe/H], respectively, which means the templates are labeled with correct stellar parameters. Through external comparisons, we confirmed that measurements of the stellar parameters through this library can achieve accuracies of approximately 125K in T_eff, 0.1 dex in [Fe/H] and 0.20 dex in log g without systematic offset. This empirical library is useful for stellar parameter measurements because it has large parameter coverage and full wavelength coverage from 3800 to 8900A., Comment: 26 pages, 19 figures, accepted by ApJS

Abstract

This is the second installment for the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) Quasar Survey, which includes quasars observed from September 2013 to June 2015. There are 9024 confirmed quasars in DR2 and 10911 in DR3. After cross-match with the SDSS quasar catalogs and NED, 12126 quasars are discovered independently. Among them 2225 quasars were released by SDSS DR12 QSO catalogue in 2014 after we finalised the survey candidates. 1801 sources were identified by SDSS DR14 as QSOs. The remaining 8100 quasars are considered as newly founded, and among them 6887 quasars can be given reliable emission line measurements and the estimated black hole masses. Quasars found in LAMOST are mostly located at low-to-moderate redshifts, with a mean value of 1.5. The highest redshift observed in DR2 and DR3 is 5. We applied emission line measurements to H$\alpha$, H$\beta$, Mg{\sc ii} and C{\sc iv}. We deduced the monochromatic continuum luminosities using photometry data, and estimated the virial black hole masses for the newly discovered quasars. Results are compiled into a quasar catalog, which will be available online., Comment: 41 pages, 13 figures, 2 electronic tables available upon inquiry, accepted by AJ

Abstract

The Macau Science Satellites (MSS‐1) mission, consisting of twin low earth orbit satellites (Satellite A and B), is the first low‐inclination and high‐precision geomagnetic surveying satellite project in China. Among the multiple scientific payloads equipped with the scientific satellites, MSS‐1 carries a GNSS radio occultation (RO) receiver on Satellite A, and aims to observe the Earth's ionosphere and monitor the space weather especially in the South Atlantic Anomaly (SAA) area. This paper focuses on the ionospheric data of MSS‐1 obtained during the first 3 months after its launch, and assesses the RO products as well as initial scintillation measurements. Results show that MSS‐1 RO data have very good agreement with contemporary COSMIC‐2 and ionosonde observations. The scintillation amplitude indices S4 are comparable with that of COSMIC‐2 and well reflect the occurrence rates and distributions of equatorial plasma bubble and sporadic E (Es) in June solstice season. Special attentions are paid to the SAA longitude sector and inspire explorations on the seasonal variations and local‐time dependences of ionospheric irregularities. Key Points: The MSS‐1 ionospheric radio occultation products are comparable with COSMIC‐2 and ionosondesScintillation characteristics in the June solstice season are well reflected based on MSS‐1 high‐rate measurements [ABSTRACT FROM AUTHOR]

The role of Social Health Insurance (SHI) in responding to the pandemic brings about an influence on insurance system sustainability. This study investigates the impact of China’s COVID-19 treatment policy on the sustainability of its SHI system, explores influences of the policy on Wuhan’s system, and discusses the effects of an assumed equivalent emergency on SHI funds for five other provincial capital cities in China.Methods: The study was conducted using pay-as-you-go actuarial models of Urban Employee Basic Medical Insurance (UEBMI) and Urban and Rural Residents Basic Medical Insurance (URRBMI) funds, which constitute China’s basic health insurance system. Current and accumulated balances of the funds in 2020 are predicted and utilized to measure the sustainability of health insurance funds during emergencies.Results: The findings suggest a disparity in the capacities of insurance schemes and localities. If the surplus before 2018 is not considered, it is likely that the URRBMI fund of Wuhan would suffer a deficit, whereas the UEBMI would retain a considerable surplus. To maintain the current actuarial balance of the URRBMI fund, coverage for ordinary inpatient and outpatient expenses would have to be significantly reduced in Wuhan, potentially affecting enrollees’ wellbeing. A similar situation may occur in three other cities, some with underdeveloped economies and lower per capita income are likely to be encountered with worse situation than Wuhan.Conclusion: Concerning fragmentation of China’s SHI system, to strengthen longer-term preparedness to manage future emergencies, this study suggests the integration of insurance schemes and provincial pooling, fund balance adjusting and an emergency safety net are also advised. All options call for more public health investments.Keywords: public health emergency, COVID-19 pandemic, public health insurance, sustainability, disparity

The objective of this study was to investigate the role of IL-17 in gastric cancer cells mediated by LCN2 binding to SLPI.Methods: The expression of LCN2 and SPLI in gastric cancer cells and transfection effects were confirmed by RT-qPCR analysis. The proliferation, clone formation ability, invasion, migration, apoptosis, and cell cycle of gastric cancer cells were in turn detected by CCK-8 assay, clone formation assay, transwell assay, wound healing assay, and flow cytometry analysis. The combination between LCN2 and SLPI was determined by co-immunoprecipitation assay. The expression of Caspase-3, Bcl-2, cyclinB1, cyclinD1, MMP9, and SLPI in gastric cancer cells was detected by Western blot analysis.Results: LCN2 and SPLI exhibited the highest levels in AGS cells, and thus AGS cells were selected for the next experiments. Down-regulation of LCN2 suppressed the proliferation and clone formation ability of AGS cells treated with IL-17. IL-17 promoted the invasion and migration of AGS cells, which was partially reversed by the down-regulation of LCN2. Down-regulation of LCN2 mediated by IL-17 promoted apoptosis and suppressed the cell cycle of AGS cells.Discussion: Down-regulation of LCN2 mediated by IL-17 suppressed the proliferation and suppressed the migration and invasion and cell cycle of gastric cancer cells by targeting SLPI.Keywords: lipocalin-2, LCN2, interleukin-17, IL-17, gastric cancer cells, SLPI

The reporter gene system was transfected into the adipose tissue-derived mesenchymal stem cell to study insulin-mediated FOXC2 expression. We also manipulated FOXC2 protein expression by either siRNA or overexpression and studied the differentiation capability of adipose tissue-derived mesenchymal stem cell into adipocytes, as well as the influence on several IR-related genes: GLUT4, PPARγ, UCP1 and PAI-1.Results: 1) Insulin effectively induced the expression of FOXC2 protein in adipose tissue-derived mesenchymal stem cells under differentiation (P< 0.01). Insulin also induced FOXC2-pro-512T promoter activity significantly (P< 0.01). 2) The stem cell adipose differentiation decreased in the FOXC2 overexpression group. 3) When FOXC2 was overexpressed, the expression of GLUT4, PAI-1 and UCP1 was higher than control groups (p< 0.001). When FOXC2 was down-regulated by siRNA, both GLUT4 and PAI-1’s protein expression were decreased (p< 0.001), and the protein expression of PPARγ was increased (p< 0.001). In the presence of insulin induction, overexpression of FOXC2 led to significantly higher UCP-1 expression (p< 0.001) and lower PAI-1 expression (p< 0.001). The protein expression of GLUT4, PAI-1 (p< 0.001) and UCP-1 (p< 0.05) was decreased in cells transfected with FOXC2 siRNA.Conclusion: Insulin effectively induced the expression of FOXC2 protein in adipose tissue-derived mesenchymal stem cells under differentiation, possibly through the regulation of the FOXC2-pro-512T promoter activity. The different protein expression of FOXC2 has regulatory effects on several genes related to insulin resistance. FOXC2 is an important regulatory factor in adipocyte differentiation and insulin resistance.Keywords: FOXC2, expression regulation, adipocyte differentiation, insulin resistance

Abstract

We derive all the O(p^6) Chiral Perturbation Theory low-energy constants from a class of gravity dual models of QCD described by the Yang-Mills and Chern-Simons Lagrangian terms, with the chiral symmetry broken through boundary conditions in the infrared. All the constants of the odd intrinsic parity sector are universally determined by those at O(p^4) in the even sector, together with an extra resonance term. A few relations for the even sector couplings are also extracted. Our estimates reasonably agree with the few available O(p^6) determinations from alternative phenomenological analyses. Some of the relations between low-energy constants are the manifestation, at large distances, of universal relations that we find between form factors in the even and odd sectors, e.g., between the gamma*->pi pi and pi->gamma gamma* matrix elements., Comment: minor changes, references added

Abstract

We report detailed measurements of the interlayer magnetoresistance of the layered organic superconductor $\kappa -(BEDT-TTF)_2Cu(SCN)_2$ for temperatures down to 0.5 K and fields up to 30 tesla. The upper critical field is determined from the resistive transition for a wide range of temperatures and field directions. For magnetic fields parallel to the layers, the upper critical field increases approximately linearly with decreasing temperature. The upper critical field at low temperatures is compared to the Pauli paramagnetic limit, at which singlet superconductivity should be destroyed by the Zeeman splitting of the electron spins. The measured value is comparable to a value for the paramagnetic limit calculated from thermodynamic quantities but exceeds the limit calculated from BCS theory. The angular dependence of the upper critical field shows a cusp-like feature for fields close to the layers, consistent with decoupled layers., Comment: 16 pages 5 figures

Background: Previous studies in multiple sclerosis (MS) showed that therapeutic inertia (TI) affects 60-90% of neurologists and up to 25% of daily treatment decisions. The objective of this study was to determine the most common factors and attribute levels associated with decisions to treatment escalation in an international study in MS care.Methods: 300 neurologists with MS expertise from 20 countries were invited to participate. Participants were presented with 12 pairs of simulated MS patient profiles described by 13 clinically relevant factors. We used disaggregated discrete choice experiments to estimate the weight of factors and attributes affecting physicians' decisions when considering treatment selection. Participants were asked to select the ideal candidate for treat-ment escalation from modest to higher-efficacy therapies.Results: Overall, 229 neurologists completed the study (completion rate: 76.3%). The top 3 weighted factors associated with treatment escalation were: previous relapses (20%), baseline expanded disability status scale [EDSS] (18%), and MRI activity (13%). Patient demographics and desire for pregnancy had a modest influence (Conclusions: Our results provide critical information on factors influencing neurologists' treatment decisions and should be applied to continuing medical education strategies.

Abstract

Background Liberating patients from mechanical ventilation (MV) requires a systematic approach. In the context of a clinical trial, we developed a simple algorithm to identify patients who tolerate assisted ventilation but still require ongoing MV to be randomized. We report on the use of this algorithm to screen potential trial participants for enrollment and subsequent randomization in the Proportional Assist Ventilation for Minimizing the Duration of MV (PROMIZING) study. Methods The algorithm included five steps: enrollment criteria, pressure support ventilation (PSV) tolerance trial, weaning criteria, continuous positive airway pressure (CPAP) tolerance trial (0 cmH2O during 2 min) and spontaneous breathing trial (SBT): on fraction of inspired oxygen (FiO2) 40% for 30–120 min. Patients who failed the weaning criteria, CPAP Zero trial, or SBT were randomized. We describe the characteristics of patients who were initially enrolled, but passed all steps in the algorithm and consequently were not randomized. Results Among the 374 enrolled patients, 93 (25%) patients passed all five steps. At time of enrollment, most patients were on PSV (87%) with a mean (± standard deviation) FiO2 of 34 (± 6) %, PSV of 8.7 (± 2.9) cmH2O, and positive end-expiratory pressure of 6.1 (± 1.6) cmH2O. Minute ventilation was 9.0 (± 3.1) L/min with a respiratory rate of 17.4 (± 4.4) breaths/min. Patients were liberated from MV with a median [interquartile range] delay between initial screening and extubation of 5 [1–49] hours. Only 7 (8%) patients required reintubation. Conclusion The trial algorithm permitted identification of 93 (25%) patients who were ready to extubate, while their clinicians predicted a duration of ventilation higher than 24 h.

Abstract

BACKGROUND: The BETTER (Building on Existing Tools to Improve Chronic Disease Prevention and Screening in Primary Care) intervention was designed to integrate the approach to chronic disease prevention and screening in primary care and demonstrated effective in a previous randomized trial. METHODS: We tested the effectiveness of the BETTER HEALTH intervention, a public health adaptation of BETTER, at improving participation in chronic disease prevention and screening actions for residents of low-income neighbourhoods in a cluster randomized trial, with ten low-income neighbourhoods in Durham Region Ontario randomized to immediate intervention vs. wait-list. The unit of analysis was the individual, and eligible participants were adults age 40-64 years residing in the neighbourhoods. Public health nurses trained as "prevention practitioners" held one prevention-focused visit with each participant. They provided participants with a tailored prevention prescription and supported them to set health-related goals. The primary outcome was a composite index: the number of evidence-based actions achieved at six months as a proportion of those for which participants were eligible at baseline. RESULTS: Of 126 participants (60 in immediate arm; 66 in wait-list arm), 125 were included in analyses (1 participant withdrew consent). In both arms, participants were eligible for a mean of 8.6 actions at baseline. At follow-up, participants in the immediate intervention arm met 64.5% of actions for which they were eligible versus 42.1% in the wait-list arm (rate ratio 1.53 [95% confidence interval 1.22-1.84]). CONCLUSION: Public health nurses using the BETTER HEALTH intervention led to a higher proportion of identified evidence-based prevention and screening actions achieved at six months for people living with socioeconomic disadvantage. TRIAL REGISTRATION: NCT03052959 , registered February 10, 2017.

Abstract

The 90K Affymetrix Axiom® Buffalo Genotyping Array has been used to genotype river buffalo samples from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil. Model-based clustering algorithms (Admixture and FastStructure software) and graph tools (Treemix and network analysis) have been applied to SNP data to evaluate the levels of molecular diversity and to highlight population structure and migration events. The best-fitting resolution devised by Bayesian clustering highlighted three distinct gene pools in pure river as well as in pure swamp buffalo populations, together with some genomic admixture occurring in the Philippines and in Brazil, in agreement with documented importations of animals for breed improvement purposes. The Mediterranean buffalo and the Carabao breed from Brazil represent the most differentiated gene pools within the river and swamp group, respectively, which is most likely due to genetic bottlenecks, isolation and selection. Gene flow events, evidenced by Treemix and Network analyses, highlighted a likely contribution from the river buffalo gene pool to the admixed swamp populations and, within river buffaloes, from the Mediterranean to the breeds from Colombia and Brazil. When evaluated in a geographical framework, the results of our analyses support archeozoological evidence for the domestication of river and swamp buffalo in the Indian subcontinent and in Southeast Asia, respectively, and furthermore revealed some unexpected patterns of migration, which suggest that the spread of domestic buffaloes out of the domestication center may have followed alternative migration routes.

Abstract

After sequencing the Buffalo genome, the International Buffalo Consortium has used the derived 90K Affymetrix Axiom® Buffalo Genotyping Array to characterize a set of river buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil. SNP genotype data have been analyzed with Bayesian clustering algorithms (ADMIXTURE software), multivariate statistics (Multi- Dimensional Scaling plots) and graph tools highlighting population splits and migration events (TREEMIX software) to estimate the levels of molecular diversity, population structure and the historical relationships among populations. When placed in the geographical context, the patterns of diversity confirmed archeozoological evidence for the domestication of river and swamp buffalo in the Indian subcontinent and in Southeast Asia, respectively, and provided hints on buffalo migrations and history. Admixture analysis revealed the presence of three main gene pools in pure river buffalo populations: one characterizes the breeds from the Indian subcontinent (Pakistan) and those recently exported from there to Bulgaria, Brazil and Colombia; the second includes breeds that, from the domestication center, spread westwards to Iran, Egypt and Turkey; the third includes the Italian Mediterranean buffalo, sampled both in Italy and in Mozambique where it has recently been exported. Among the breeds analysed, Mediterranean buffalo represents the most differentiated river buffalo gene pool, which is most likely due to genetic bottlenecks, isolation, selection and possible genetic contributions from breeds not included in our sampling. Four gene pools have been identified in pure swamp buffalo populations: the first from China; the second in Indonesian islands, other than Sumatra; the third in the Philippines and the fourth in Thailand and Sumatra. Some level of admixture is seen between river and swamp buffalo in the Philippines and in Brazil. TREEMIX software analyses confirmed the gene flows identified by Bayesian population structure analysis including those from the river buffalo gene pool to the admixed swamp populations and, within river buffaloes, from the Mediterranean to the breeds from Colombia and Brazil. Furthermore, these analyses revealed some unexpected migration patterns, which suggest that the westward spread of domestic buffaloes may have followed alternative migration routes.

Abstract

Medical Council on Alcohol and Oxford University Press. All rights reserved. Aims: Despite the introduction of national drinking guidelines in Canada, there is limited public knowledge of them and low understanding of 'standard drinks (SDs)' which limits the likelihood of guidelines affecting drinking behaviour. This study tests the efficacy of alcohol labels with SD information and Canada's Low-Risk Drinking Guidelines (LRDGs) as compared to %ABV labels on consumers' ability to estimate alcohol intake. It also examines the label size and format that best supports adults' ability to make informed drinking choices. Methods: This research consisted of a between-groups experiment (n = 2016) in which participants each viewed one of six labels. Using an online survey, participants viewed an alcohol label and were asked to estimate: (a) the amount in a SD; (b) the number of SDs in an alcohol container and (c) the number of SDs to consume to reach the recommended daily limit in Canada's LRDG. Results: Results indicated that labels with SD and LRDG information facilitated more accurate estimates of alcohol consumption and awareness of safer drinking limits across different beverage types (12.6% to 58.9% increase in accuracy), and labels were strongly supported among the majority (66.2%) of participants. Conclusion: Labels with SD and LRDG information constitute a more efficacious means of supporting accurate estimates of alcohol consumption than %ABV labels, and provide evidence to inform potential changes to alcohol labelling regulations. Further research testing labels in realworld settings is needed. Short summary: Results indicate that the introduction of enhanced alcohol labels combining standard drink information and national drinking guidelines may be an effective way to improve drinkers' ability to accurately assess alcohol consumption and monitor intake relative to guidelines. Overall support for enhanced labels suggests probable acceptability of introduction at a

Abstract

Several experimental studies have been reported as evidence of Josephson coupling between the superconducting layers in the highly anisotropic oxide such as the Bi2Sr2CaCu2O8 and Tl2Ba2CuO6 systems. These include the large penetration depth of 100 mu m measured, ac and dc Josephson effects. Recently two critical temperatures corresponding to Josephson coupling in between the layers and the Berezinskii-Kosterlitz-Thouless transition in the ab-plane have been directly observed in the transport measurements. If the field is applied parallel to the superconducting layers, the magnetic excitation is not the conventional Abrikosov vortices, but the Josephson vortices which extend lambda(sub ab) in the c-axis direction and lambda(sub J) = gamma s in the plane (s is the interlayer distance, gamma is the anisotropy constant). Because of the weak screening effect associated with the Josephson vortices, there have been predictions of magnetic transparent states at magnetic field above a characteristic field H(sub J), a behavior distinctively different from that of the type-II superconductors. In this paper, we report an experimental result which illustrates a transition from the Meissner state to the magnetic transparent state in single crystal of Nd(1.85)Ce(0.15)CuO(4-y). Magnetization has been measured as a function of temperature and field in the magnetic field parallel or close to ab-plane geometry. For a fixed magnetic field, the magnetization shows a two-step transition in M(T); for a fixed temperature, the magnetization shows an abrupt change to almost zero value above a characteristic field H(sub J), an indication of magnetic transparent state. The data of magnetization as a function of field clearly deviates from the behavior predicted by the Abrikosov theory for type-II superconductors. Instead, the data fit well into the picture of Josephson decoupling between the CuO2 layers.

Abstract

Transport measurements of interlayer magnetoresistance were performed on a highly two-dimensional organic superconductor beta'-(BEDT-TTF)2SF5CH2CF2SO3. The magnetoresistance was found to exhibit a pronounced peak as a function of magnetic field below the superconducting transition temperature similar to that of kappa-(BEDT_TTF)2X compounds. This similarity suggested that the magnetoresistance peak is intrinsic to the layered systems.

Abstract

This study develops a vehicle-pedestrian safety application for signalized urban crossings in a connectedautomated vehicle (CAV) environment and establishes a microscopic simulation environment to implement the safety application using a highly flexible open-source simulation tool. A widely-used surrogate safety measure (SSM) namely, post-encroachment time (PET), is used to capture the number of conflicts. A reinforcement learning algorithm is used to train the CAV agents to determine the optimal timing to cross the intersection with the consideration of pedestrian safety. A variety of real-world datasets are used to calibrate and validate the simulation environment. The simulation results show that the pedestrian safety application can significantly reduce the number of potential conflicts, and the reinforcement-leaming-trained CAV agents have demonstrated lower average travel times when crossing intersections.
