title: Long-Distance Ranging and Velocity Measurements by REASON on Europa Clipper

description: One of the objectives of the Gravity and Radio Science (G/RS) instrument on NASA’s Europa Clipper mission is to improve our knowledge of Europa’s ephemerides, to trace the moon’s thermal-orbital evolution. Here, we present a complementary methodology to use the Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) instrument to enhance these measurements by tracking echoes from Europa at greater distances, beyond its primary role of subsurface sounding during close flybys. We investigate the possibility of occasional REASON measurements during the non-nadir phase at altitudes beyond 40,000 km to extend the ephemerides dataset. Through radar simulations of REASON’s echoes, we evaluate and demonstrate this approach by determining the maximum altitude for surface return detection, achieved by coherently processing hundreds to thousands of pulses within the signal’s round-trip time. The received signal’s power can be further enhanced by maximizing pulse length, targeting Europa’s most reflective (leading sub-Jovian) hemisphere, and summing many compressed pulses. We also explore a phase shift approach for velocity measurements, which uses existing ranging pulses. Using Europa Clipper’s most recent trajectory design, we identify flybys that align with the best working scenarios for this approach. Our performance estimates for range and velocity resolution demonstrate that this approach could obtain measurements relevant to Europa’s ephemerides. This method offers key insights into Europa’s orbital evolution and, ultimately, its long-term habitability.

title: Congo Basin Carbon Cycle Responses to Global Change

description: The Congo Basin and its contiguous forests harbor globally significant carbon stocks, estimated at 65 gigatons of C (GtC) above and belowground. Despite rising temperatures and intensifying droughts, they have remained a carbon sink, albeit weak: 0.26–0.50 GtC yr⁻¹ carbon uptake since 1980. However, these forests’ carbon stocks and fluxes, including gross primary productivity, respiration, net primary productivity, and riverine carbon transport, remain poorly quantified. This limits understanding of the region’s role in the global carbon cycle, its vulnerability to environmental change, and its potential as a long-term carbon sink. We review and quantify Congo Basin and contiguous forest carbon stocks and fluxes and synthesize the current knowledge on how key global-change drivers shape the region’s carbon cycle. We find limited responses to long-term precipitation variability, but declining stocks and fluxes in response to long-term and increasing temperature and drought frequency. Land cover and land use change, largely driven by small-scale agriculture, logging, and agro-industrial expansion, reduces carbon stocks, ecosystem structure and functioning, and animal-mediated ecosystem services. Large-scale savanna biomass burning delivers phosphorus and nitrogen to Congo Basin forests via cross-equatorial winds, providing additional nutrients and supporting carbon sequestration. In situ studies suggest that CO₂ fertilization has increased intrinsic water-use efficiency, although its effects may be modulated by climate change, and its impacts on biomass accumulation remains uncertain. Legacy effects from historical land use and climate change likely shaped present-day vegetation structure, yet their relative influence is unclear. High-resolution carbon monitoring, improved remote sensing, and strengthened in situ measurement networks are needed to quantify the impacts of these key drivers and their interactions on the Central African carbon cycle. This is needed to inform conservation strategies and advance understanding of the region’s future as a carbon sink under global change pressures.

title: Thermal Stability and Performance of Li-ion Batteries at Elevated Temperatures: Separator Effects

description: Lithium-ion batteries have been optimized for a limited temperature range (ca. 0-40 °C) and experience rapid capacity fade at elevated temperature (&gt;50 °C). Cycling data and design of experiment (DOE) studies establish that the commonly used polyolefin-based separator is an important factor contributing to poor battery performance at elevated temperatures upwards of 100 oC. Understanding this failure mechanism is key to unlocking solutions that broaden the operating temperature range, enabling new applications in space exploration, drilling equipment, and automotive technologies. Here, an in-depth analysis was undertaken of the high-temperature failure mechanisms for cells containing a trilayer polypropylene/polyethylene/polypropylene (PP/PE/PP) separator with either a LiNi0.33Mn0.33Co0.33O2 (NMC111) or LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode, a graphite anode, and an electrolyte composed of 1.0 M LiPF6 in ethylene carbonate:ethyl methyl carbonate (EC:EMC, 1:1 v/v). Electrochemical methods consisting of coin cell cycling and electrochemical impedance spectroscopy (EIS) revealed capacity loss, reduced coulombic efficiencies, and large resistance increases during prolonged exposure at 100 °C for trilayer separators relative to polyimide separators. Spectroscopic measurements showed inhomogeneities within the heated, trilayer separator with localized deformations, indicating that increasing temperatures cause the porosity to decrease until complete continuity was observed. Tensile and puncture testing revealed that a 100 °C environment was the dominant factor decreasing tensile strength and increasing variability. Overall, this study identifies multiple failure mechanisms associated with polyolefin separators in cells cycling at 100 °C.

title: Organic Cofactors in the Electron Transport Chain: Properties and Connection the Prebiotic World

description: Metabolism is a critical process for biology and is of great interest to those researching geobiological processes and the origins of life. It represents a network of chemical reactions for molecular synthesis, energy conversion pathways, and cellular function. Understanding the mechanisms underlying metabolic processes gives insight into the evolution of the electrochemical processes of complex systems and informs the possible pathways by which abiotic chemistry transitioned to biochemistry. Modern proteins and enzymes utilize cofactors to mediate chemical reactions, overcoming energetic limitations. While enzymes are specific, large, and complex biological proteins, cofactors are simpler ions and molecules incorporated within the larger protein complex. Cofactors fundamentally supplement an enzyme’s catalytic role and may represent a convergence between abiotic and biotic chemistry, allowing studies of cofactors to reveal potential prebiotic processes. Here we review some of the organic nucleotide cofactors participating in the electron transport chain: their structures, capacity for energy conversion, and their putative role in the origins of life. We then make recommendations for future research topics and avenues.

title: Europa Clipper: First Year of Space Flight Operations

description: Europa Clipper launched at 16:06 UTC on 14 October 2024, on a fully expendable SpaceX Falcon Heavy launch vehicle. It utilizes planetary gravity assists from Mars and Earth via a Mars-Earth Gravity Assist trajectory in two solar orbits over 5.25 years to reach the Jupiter system and explore the ocean world Europa. The launch phase was a critical event focused on putting the Flight System onto its interplanetary trajectory and completing critical deployment of the solar array. Following completion of the autonomous activities, the ground successfully established two-way communication to determine Flight System health and orbit. Europa Clipper’s mission plan for interplanetary cruise leading up to the Mars flyby on 1 March 2025 was for the majority (but not all) of the first-time activities to take place during two characterization periods, known as Flight System Characterization Parts 1 and 2 (FSC1 and FSC2, respectively). All checkouts and deployments that enable the first trajectory correction maneuver (TCM-1) were defined as FSC1, while almost all the remaining checkout activities were defined as FSC2. FSC2 concluded roughly three months after launch, prior to entering a low data rate period. The Mars flyby aﬀorded the opportunity to perform a key calibration for the Europa Thermal Emission Imaging System (E-THEMIS) and a flyby functional test for the Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) instruments. By early May, Europa Clipper had a heliocentric distance over 2 AU, by which the Flight System could point the High Gain Antenna at Earth for an unlimited duration; periodic and episodic maintenance, calibration, and navigation activities continued during this period. This paper presents the overall strategy, plan, process, and early flight results and performance for Europa Clipper’s first year of flight operations, including in-flight navigation and Flight System characterization. It also describes interesting and unique operations challenges encountered and overcome in flying Europa Clipper.

title: A digital holographic microscope for high-resolution characterization of metasurface optics in the short-wave infrared

description: There exists a family of optical components used in high-contrast imaging that are essential to achieving performance goals, yet are challenging to fabricate and characterize. This is due to the spatial scales involved, and the requisite manufacturing control needed in this microscopic domain. These elements can be broadly characterized as focal plane masks because they work on the the diffraction-limited focal plane electric field. They include such devices as occulting disks for the classic Lyot coronagraphs, vector-vortex liquid crystal masks, scalar metasurface vortex masks, and Zernike phase-contrast masks (both scalar and vector). Designing, fabricating, and characterizing these focal plane masks at fine spatial scales is an essential and necessary part of closing the loop around the design and development process. Here we present the use of a digital holographic microscope (DHM) that is tailored to the testing and characterization of these masks. We illustrate the operation of this new DHM instrument with data from a couple of different metasurface devices - one scalar and one vector - to showcase the application and utility of the device.

title: 'Toccate per Cimbalo del Signor Domenico Scarlatti': An Unexplored Early Source

description: English Abstract
The loss of musical autographs by Domenico Scarlatti (1685–1757) makes it difficult to date and
establish a reliable chronological order for his keyboard sonatas. A previously unexplored source
now sheds new light on the composer’s early period: a manuscript contained in a miscellaneous
codex preserved at the Bibliothèque de l’Arsenal in Paris (F-Pa MS-6785 (F-Pa Ms-6785, [https://
archivesetmanuscrits.bnf.fr/ark:/12148/cc86681q]). This source includes a collection of twentyone
sonatas by Scarlatti, copied by two anonymous scribes.
This article examines the activity of each copyist and the paper’s watermarks. The findings
indicate that the manuscript originated in France, and was based on drafts of individual sonatas
stemming from an Italian context. A philological analysis confirms that this new source derives
from Scarlatti’s autographs. A comparison between this manuscript and the first pieces published
in Paris (Pièces choisies pour le clavecin ou l’orgue [Boivin, 1737]) reveals that it could not have
been based on that edition, nor on its antigraphs. Rather, it must have arrived in France at an
earlier date, derived from an Italian antigraph. This source represents the most extensive surviving
collection of early sonatas circulating in manuscript from across Europe prior to the printed
dissemination of Scarlatti’s keyboard works.

title: New chalcone tethered pyrazole derivatives: synthesis, molecular docking, ADME-T & DFT study

description: The chalcone scaffold pyrazole is important in organic and medicinal chemistry. This study presents the design and synthesis of new chalcone-coupled pyrazole derivatives (1a-1o). The new compounds were characterized using FT-IR, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR, GC-MS, elemental analysis, and cytotoxic analysis on MCF-7 and HepG2 cancer cell lines. The synthesized compounds also underwent molecular docking, ADMET (absorption, distribution, metabolism, excretion, and toxicity), and DFT (density functional theory) studies. Compound 1a showed high cytotoxic activity against MCF-7 cells (LC<sub>50</sub>, 0.62 ± 0.01 µM), outperforming standard Doxorubicin. Compounds were examined using molecular docking, ADME-T, and DFT calculations. Compound 1a had a higher binding affinity (−10.8 Kcal/mol) than Doxorubicin (−4.7 Kcal/mol). ADME-T profile and pharmacokinetic predictions were performed on the analogs. DFT with the B3LYP/6–311++G (DP) basis set helped determine optimal shape and dimensions. Additional Gaussian 16-based DFT calculations were conducted on compounds (1a-1o). The HOMO-LUMO analysis revealed compound 1a had a significant energy gap (2.5056 eV, from −7.94026 eV to −5.43465 eV). Compound 1a may be a promising anti-cancer agent.

title: OpenFOAM files and results data for: A wall-modeled large eddy simulation framework for sheared convective atmospheric boundary layers

description: This data repository contains the OpenFOAM simulation data and results using the wall-modeled large-eddy simulations (WMLES) framework for high-Reynolds-number sheared convective atmospheric boundary layer (ABL). The proposed framework enables accurate and computationally efficient CBL inflow generation for wind farm simulations in modern HPC systems by employing ABL-tailored wall functions along with a non-uniform grid and a TVD scheme, laying the groundwork for future studies involving surface roughness, heterogeneity, terrain complexity, and advanced wall-model formulations.

The dataset contains three main folders corresponding to the simulations on the non-uniform grid using the ABL-tailored wall function, the universal law of the wall, and Reichardt's law. Each folder contains the mandatory folders required to run the OpenFOAM simulations, i.e., "0", "constant", and "system" folders; and also results in "25000" and "postProcessing" folders. The velocity streamwise (Ux) and vertical (Uy) components of velocity, potential temperature (T), the subgrid-scale (SGS) viscosity (nut), and thermal diffusivity (alphat) at 25000s simulation-time are located in the "25000" folder. The temporal evolution of the dimensionless wall distance (z⁺) values throughout the simulation are included in the "postProcessing" folder. Lastly, the *.foam file allows the user to open the case using Paraview. Users interested in viewing the grid can run the blockMesh command. It will generate the grid folder "polyMesh" inside the "constant" folder.

title: De-identified Clinical Administrative Dataset for Metabolic Disease Risk Analysis from RSI Banjarnegara, Indonesia

description: This dataset contains de-identified clinical administrative records of patients diagnosed with metabolic-related diseases, including diabetes mellitus, hypertension, and stroke, collected from Rumah Sakit Islam (RSI) Banjarnegara, Central Java, Indonesia. The dataset reflects patient management and service utilization characteristics rather than detailed physiological or laboratory measurements.

All personal identifiers have been fully removed to ensure patient anonymity and compliance with ethical research standards. The dataset includes demographic attributes, service unit codes, case status, and diagnostic indicators, making it suitable for exploratory analysis, risk stratification, and machine learning–based predictive modeling in healthcare research.

This dataset was primarily used for developing and evaluating artificial intelligence models (ANN, KNN, and hybrid ANN–KNN) for metabolic disease risk prediction under resource-constrained settings. Due to the scarcity of publicly available Indonesian clinical datasets, this dataset is expected to support future research on lightweight AI, health data analytics, and decision support systems in developing-country contexts.
