title: hermal Performance of the Perseverance Rover During Mars Surface Operations

description: On July 30, 2020, NASA launched the Perseverance Rover as part of the Mars 2020 (M2020) mission to Mars. On February 18, 2021, the rover landed on the surface of Mars in Jezero Crater at a latitude of 18.5°N. As of the writing of this paper, the rover has completed over 700 sols of surface operations, more than one full Martian year on the surface. Landing occurred during the Martian spring (Ls=5), and the rover has since operated through the summer, fall, and winter seasons. While the rover was originally designed to support a surface mission of 1003 sols, Perseverance has been integrated as part of the planned Mars Sample Return (MSR) Campaign to bring samples back from the surface of Mars to Earth for the first time. Understanding the thermal performance of the rover will be essential to ensuring the longevity of Perseverance to perform this mission. This paper discusses the thermal performance of the rover from landing to present day, including predicted versus actual thermal performance, nominal operations, incidents and anomalies, and long-term trending data that will be used to improve energy usage for activities requiring thermal support in the future.

title: Antidiabetic activity of aqueous extract of Sigesbeckia orientalis (St. Paul’s Wort) in alloxan-induced diabetes model

description: The current study evaluated antidiabetic and antihyperlipidemic activities of aqueous extract of Sigesbeckia orientalis L. (St. Paul’s Wort) (AESO) in an alloxan-induced diabetic rat model. Following OECD guidelines safe doses of AESO were assessed in rats for the main study. Serum/bood glucose, α-amylase, and lipids levels and histopathological evaluations were conducted to assess antidiabetic and associated antihyperlipidemic efficacies of AESO. AESO was found to be safe up to the dose of 2000 mg/kg. Significant (p &lt; 0.05) reduction in glucose and lipids (total cholesterol, triglycerides, low-density lipoproteins) levels was observed in AESO treatment groups. Serum α-amylase, high-density lipoproteins, and total body weight was increased significantly (p &lt; 0.05) in diabetic rats treated with AESO. Histopathological data showed improvement in hepatocyte and pancreatic β-cells islets architecture. HPLC analysis identified quercetin, gallic acid, vanillic acid, p-coumaric acid, m-coumaric acid and cinnamic acid in AESO which are suggested to be responsible for observed antihyperglycemic and antihyperlipidemic attributes. Further studies to standardise the extract and evaluation of safety profile in long-term toxicity studies are recommended for safe and effective antidiabetic nutraceuticals development.

title: Mean Seagrass Meadow Metabolism by Time of Day in Virginia, USA

description: The study examined benthic O2 fluxes over a seagrass meadow using the aquatic eddy covariance technique, while measuring variables that have been shown to affect metabolism (PAR, temperature, O2 concentration, current velocity). 
 Accurate daily metabolic estimates of respiration, gross primary production, and net ecosystem metabolism are widely used to assess ecosystem health and blue carbon sequestration and storage in vegetated coastal ecosystems. Aquatic eddy covariance allows direct measurements under naturally varying in situ conditions of oxygen (O2) fluxes between a benthic substrate and the water above. Here, we used hourly O2 fluxes measured with this approach to examine how respiration for a Zostera marina seagrass meadow varies through night and day, and how this affects commonly performed metabolic estimates. Fitting our database of 2,115 hourly benthic O2 fluxes for a seagrass meadow revealed that respiration decreased linearly by 29% through the night. We primarily attribute this to consumption of highly labile compounds that are formed by photosynthesis and accumulate during daytime. Furthermore, a corresponding linear increase in respiration through the day coupled with photosynthetic production described by a standard photosynthesis irradiance curve provided an accurate prediction of measured O2 fluxes (R2 = 0.993). These results document that night- and daytime respiration vary significantly in a seagrass meadow, and that both can be described accurately by a piecewise linear relationship. Many studies have questioned the widely used assumption in metabolic estimates that night- and daytime respiration are constant and equal. However, if night- and daytime respiration can be approximated as we found here by piecewise linear relationships, these standard means for calculating daily metabolic numbers remain valid. It is, however, important that such estimates are based on full 24-h records of benthic flux data.

title: Covariance Based Terrain Mapping for Autonomous Mobile Robots

description: Autonomous mobile robots operating in unknown terrain have to guide their drive decisions through perception. Local mapping and traversability analysis are essential for safe rover operation and low level locomotion. This paper deals with the challenge of building a local, robot-centric map from onboard range sensing. We introduce a new highly-efficient converging covariance based map update for estimating a digital elevation map. The map is capable of representing sub-cell size obstacles and can be queried for height, the presence of obstacles, and slope in constant time. Extensive experiments in simulation and real world test campaigns are used to evaluate the performance of our approach. The presented mapping technique outperforms state of the art grid-mapping algorithms for computationally constraint systems in run time, memory usage, precision and resolvable obstacle size. Further application scenarios are discussed. A variant of this map approach is projected to be used on NASA’s 2024 CADRE mission to the Moon.

title: SNN-PDE: Learning Dynamic PDEs from Data with Simplicial Neural Networks

description: Dynamics of many complex systems, from weather and climate to spread of infectious diseases, can be described by partial differential equations (PDEs). Such PDEs involve unknown function(s), partial derivatives, and typically multiple independent variables. The traditional numerical methods for solving PDEs assume that the data are observed on a regular grid. However, in many applications, for example, weather and air pollution monitoring delivered by the arbitrary located weather stations of the National Weather Services, data records are irregularly spaced. Furthermore, in problems involving prediction analytics such as forecasting wildfire smoke plumes, the primary focus may be on a set of irregular locations associated with urban development. In recent years, deep learning (DL) methods and, in particular, graph neural networks (GNNs) have emerged as a new promising tool that can complement traditional PDE solvers in scenarios of the irregular spaced data, contributing to the newest research trend of physics informed machine learning (PIML). However, most existing PIML methods tend to be limited in their ability to describe higher dimensional structural properties exhibited by real world phenomena, especially, ones that live on manifolds. To address this fundamental challenge, we bring the elements of the Hodge theory and, in particular, simplicial convolution defined on the Hodge Laplacian to the emerging nexus of DL and PDEs. In contrast to conventional Laplacian and the associated convolution operation, the simplicial convolution allows us to rigorously describe diffusion across higher order structures and to better approximate the complex underlying topology and geometry of the data. The new approach, Simplicial Neural Networks for Partial Differential Equations (SNN PDE) offers a computationally efficient yet effective solution for time dependent PDEs. Our studies of a broad range of synthetic data and wildfire processes demonstrate that SNN PDE improves upon state of the art baselines in handling unstructured grids and irregular time intervals of complex physical systems and offers competitive forecasting capabilities for weather and air quality forecasting.

Le site se situe le long de l'autoroute A42 sur une superficie d'environ 18 hectares. Le projet fait l'objet d'une autorisation environnementale unique en raison de certaines espèces présentes sur site. Le site d’étude se localise dans la continuité du tissu urbain à vocation économique existant, il prend place sur un secteur à faible attractivité pour la faune, en raison de la présence de l’autoroute A42 et de l’urbanisation environnante. Les parcelles concernées par la ZAC des Goucheronnes ne sont pas identifiées au SRCE Rhône-Alpes comme faisant partie des grands espaces agricoles participant de la fonctionnalité écologique du territoire. Le secteur ne présente pas de zone humide. Les habitats et la flore présentent un enjeu faible. Certaines espèces faunistiques présentent des enjeux forts (oiseaux, amphibiens, insectes). Le site présente des enjeux écologiques nul à fort : - Les enjeux sont forts pour le petit gravelot, le crapaud calamite et l’agrion de mercure ; - Les enjeux sont modérés pour la majeure partie de l’avifaune et le lapin de garennes (mammifère) ; - Les enjeux sont faibles concernant les reptiles, les chiroptères et certains mammifères. L’aménagement proposé sera sensible à la sauvegarde, au maintien et à la prise en considération de ce patrimoine. Les trames vertes, ou continuités végétales observées seront considérées avec la plus grande attention. Il conviendra alors de recenser le patrimoine naturel sur chaque séquence, de connaître les essences présentes, leur implantation et le paysage qu’elles proposent. In fine, l’objectif sera de renforcer au maximum cette biodiversité.

title: Quantifying Uncertainty in AtmosphericWinds Retrieved from Optical Flow: Dependence on Weather Regime

description: This study explores the performance of a dense optical flow method in comparison to pattern matching techniques for retrieving Atmospheric Motion Vectors (AMVs) from water vapor images. Using high-resolution simulated datasets that represent various weather phenomena, we assess the performance of these methods across different weather regimes, time intervals, and pressure levels, and quantify the uncertainties associated with retrieved winds. The optical flow algorithm consistently outperforms the feature matching approach. Notably, it produces wind speeds and AMVs that closely resemble the wind fields from the simulations, and unlike the feature matching algorithm, the optical flow algorithm exhibits consistent performance across different time intervals. In contrast, the feature matching approach yields vector fields that exhibit over-smoothing in certain areas and erratic behavior in others, while also producing less detailed, regionally constant speed maps. Furthermore, unlike feature matching, the optical flow method effectively calculates AMVs even in areas with low wind speeds and near regions with missing data, generating a dense AMV field for every pixel in a pair of images. This superior performance and flexibility significantly influence the planning for future satellite missions aimed at retrieving atmospheric winds. As such, our work plays a critical role in determining the mission architecture and projected instrument performance for future atmospheric wind retrieval satellite missions. The study underscores the potential of the optical flow algorithm as a robust and efficient approach for atmospheric motion retrieval, thus contributing to advances in climate research and weather prediction.

title: A Microwave Photonic Oscillator Based on Self-Injection Locking to a Fabry-Perot Cavity

description: We demonstrate an efficient simultaneous self-injection locking of two semiconductor lasers to high-order modes of a stand-alone monolithic Fabry-Perot cavity. The lasers are used to generate a low noise microwave signal on a fast photodiode. The overall improvement of the laser spectral purity exceeds 80 dB. The observed single-sideband phase noise of X- to Ka-band signals is at the -110 dBc/Hz level and is limited by the funda- mental thermorefractive noise of the cavity. The demon- strated cavity-laser configuration can be tightly pack- aged and is promising for generation of high frequency RF signals as well as for referencing optical frequency combs.

title: SMAP Antenna Pointing Error Estimation Using GNSS-Reflectometry

description: This manuscript explores the use of Global NavigationSatellite System – Reflectometry (GNSS-R) data collected by theSoil Moisture Active Passive (SMAP) mission to estimate antennaview angle offsets. A novel methodology for estimating antennaview angle offsets using GNSS-R data is proposed by comparingthe received Signal-to-Noise Ratio (SNR) of the reflected GNSSsignal with SMAP’s antenna pattern measured prior to launch. Toproperly compare them, observation angles are defined withrespect to the SMAP position and the specular point position,which are computed from the SMAP telemetry and the GPSephemeris data using a 1-km resolution digital elevation modelmap. A methodology based on a 2nd order polynomial fit and alinear fit is proposed to estimate the offset by azimuthal sector andat different times of the year. Results are obtained for a total of 6years, showing a consistent dependence on the antenna azimuthallook angle and on the time of the year, with an average antennaoffset of 0.2° with a standard deviation of 0.06°, which produces ageolocation error of ~ 3.6 km. Further analysis proposes a nonlinearmodel to estimate the antenna offset directly from anazimuthal look angle and the time of the year. Model results showa Pearson correlation coefficient of R = 0.85 and R = 0.80 fordescending and ascending passes, respectively. This model can beused by the SMAP team to further correct the antenna footprintlocation and pointing angle.
