title: Modelling the Brittle Rock Failure by the Quaternion-based Bonded-Particle Model in DEM

description: This research investigates brittle rock failure using a quaternion-based bonded-particle model within the discrete element method (DEM). Unit quaternions represent particle spatial rotations, enabling the computation of relative displacements and bonding forces. Validation is achieved through uniaxial compression tests, yielding good agreement with established experimental data. Findings reveal that stress oscillation, uniaxial compression strength, and failure patterns in solids are predominantly influenced by the loading strain rate. Increasing strain rates lead to intensified oscillations in the strain-stress curve due to force wave interactions and solid deformation inertia. A quasi-static loading condition with minimal stress oscillation is attainable only at very low loading strain rates. Brittle failure initiates with the nucleation of internal damage, forming interconnected failure planes that grow in area with increasing loading strain rates, ultimately transforming the failure pattern from localized damage to complete fragmentation.

title: PROTEINS RELATED TO PATHOGENESIS OF DISEASES, VIRAL PROTEINS, CELL DIVISION, SIGNALLING AND CHROMATIN PROCESSES

description: The outstanding research questions of our BAG focus on proteins and their complexes involved in a variety of processes, ranging from cell homeostasis (from gene regulation to folding quality control, from energy metabolism to signal transduction) to communication and surface recognition (including trans-interactions between cell adhesion molecules, components of the extracellular matrix weaving, as well as antigen-antibody interactions for vaccine development and optimization). Key to several projects is the characterization of the mechanisms associated to enzyme function in various organisms, including bacteria, viruses, plants, animals and humans for downstream drug discovery campaigns. Emphasis is also given to research focusing on engineering protein and enzymes for future industrial applications, as well as to understand the impact of pathogenic mutations on protein structures, providing a genotype-to-molecular phenotype rationale to disease development.

title: Multi-instrument Image Correlation for In Situ Planetary Science on Mars 2020

description: The Mars 2020 Perseverance rover is equipped with 23 cameras that aid in science operations and investigations [1]. The cameras on Perseverance image from the scale of tens of meters down to tens of microns, enabling detailed visual analysis of the martian surface across spatial scales. Some of these cameras are co-boresighted to spectrometers, allowing for the acquisition of spatially resolved compositional data. Integrating images from multiple different cameras is a challenge due to differences such as angle of acquisition, illumination, resolution, and pixel scale. However, combining these data enables a more comprehensive understanding of each target of interest by utilizing the complementary advantages of each imager or instrument. Here, we present two case studies that highlight the utility of computer vision to address science needs and improve science return of in situ analyses. In the first, we apply keypoint detection and matching to align images from two mapping spectrometers, thus allowing for complementary analysis with Raman spectroscopy and X-ray Fluorescence spectroscopy. We extend this case study by aligning images from two different cameras to yield a high-resolution blended composite that captures both texture and color information. In the second case study, we apply fast color transfer algorithms to adjust images taken by the same camera of many different rock targets, thus enabling a better comparison of textures and colors irrespective of lighting conditions during acquisition. We further apply this approach to match colors across images taken from different cameras to evaluate the similarity of the collected sample to the proxy abrasion patch on the parent rock.

title: The High Energy X-ray Probe (HEX-P): Bringing the Cosmic X-ray Background into Focus

description: Since the discovery of the cosmic X-ray background (CXB), astronomers have strived to understand the accreting supermassive black holes (SMBHs) contributing to its peak in the 10--40 keV band. Existing soft X-ray telescopes could study this population up to only 10 keV, and, while NuSTAR (focusing on 3-24 keV) made great progress, it also left significant uncertainties in characterizing the hard X-ray population, crucial for calibrating current population synthesis models. This paper presents an in-depth analysis of simulations of two extragalactic surveys (deep and wide) with the High-Energy X-ray Probe (HEX-P), each observed for 2 Ms. Applying established source detection techniques, we show that HEX-P surveys will reach a flux of ~1e-15 erg/cm2/s in the 10-40 keV band, an order of magnitude fainter than current NuSTAR surveys. With the large sample of new hard X-ray detected sources (~2000), we showcase HEX-P's ability to resolve more than 80% of the CXB up to 40 keV into individual sources. The expected precision of HEX-P's resolved background measurement will allow us to distinguish between population synthesis models of SMBH growth. HEX-P leverages accurate broadband (0.5-40 keV) spectral analysis and the combination of soft and hard X-ray colors to provide obscuration constraints even for the fainter sources, with the overall objective of measuring the Compton-thick fraction. With unprecedented sensitivity in the 10-40 keV band, HEX-P will explore the hard X-ray emission from AGN to flux limits never reached before, thus expanding the parameter space for serendipitous discoveries. Consequently, it is plausible that new models will be needed to capture the population HEX-P will unveil.

title: Remote sensing of soil moisture using Rydberg atoms and satellite signals of opportunity

description: Spaceborne radar remote sensing of the earth system is essential to study natural and man-made changes in the ecosystem, water and energy cycles, weather and air quality, sea level, and surface dynamics. A major challenge with current approaches is the lack of broad spectrum tunability due to narrow band microwave electronics, that limit systems to specific science variable retrievals. This results in a significant limitation in studying dynamic coupled earth system processes such as surface and subsurface hydrology, where broad spectrum radar remote sensing is needed to sense multiple variables simultaneously. Rydberg atomic sensors are highly sensitive broad-spectrum quantum detectors that can be dynamically tuned to cover micro-to-millimeter waves with no requirement for band-specific electronics. Rydberg atomic sensors can use existing transmitted signals such as navigation and communication satellites to enable remote sensing. We demonstrate remote sensing of soil moisture, an important earth system variable, via ground-based radar reflectometry with Rydberg atomic systems. To do this, we sensitize the atoms to XM satellite radio signals and use signal correlations to demonstrate use of these satellite signals for remote sensing of soil moisture – a step towards broad spectrum atomic remote sensing.

title: The Goldstone Apple Valley Radio Telescope (GAVRT) Search for Extra Terrestrial Intelligence (SETI)

description: This paper reports the results from a student-led Search for Extraterrestrial Intelligence (SETI), also known as technosignatures, targeting the plane of the Milky Way Galaxy as a part of the Gold-stone Apple Valley Radio Telescope (GAVRT) collaboration between the Lewis Center for Educational Research (LCER) and the Jet Propulsion Laboratory (JPL). Students associated with LCER submit analytic reports of spectral data targeting specific regions of the Milky Way, identifying interference, noise, and Candidate signals potentially originating from intelligent sources. GAVRT SETI’s search is guided by the assumption that a narrow-band radio signal (&lt;1.5Hz) from a fixed location in the sky, occurring across multiple observation periods, is unlikely to be caused by instrument noise or by a natural source. Thus, we searched the reported data for similar signals occurring during different observation periods within the same region of sky. No such signals were found. However, our analysis of the frequency distribution of Candidates suggests that at least a few percent of the Candidates are associated with low-level radio-frequency interference (RFI).
