Donor-Specific Transplant Outcomes From Bmt Ctn 1702: A Multicenter Prospective Biologic Assignment Trial, Asad Bashey, Iskra Pusic, Et Al.

2020-Current year OA Pubs

Newer approaches to control alloreactivity may produce similar transplant outcomes using HLA-mismatched donors vs HLA-matched unrelated donors (MUD). However, prospective comparisons are lacking. BMT CTN 1702 used a donor search prognosis score to assign patients to an 8/8 HLA MUD or the center's preference of haploidentical related donors (HAPLO), mismatched unrelated donors (MMUD), or umbilical cord blood (UCB). Outcomes of MUD were compared to HAPLO, MMUD, and UCB transplantation after adjusting for covariates. Patients (n = 1179 [93% adults]) underwent transplantation with MUD (n = 772), HAPLO (n = 254), MMUD (n = 112), and UCB (n = 41) at …

Optimizing Ball‐Milled Composites For Fast Energy Release Under Shock Compression, Siva Valluri, Edward Dreizin, Dana Dlott

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Microparticle additives containing both Al fuel and oxidizer, fabricated by arrested reactive milling (ARM), could potentially increase the power of energetic materials such as HMX because they contain premixed fuel and oxidizer. Optimizing shock reactivity requires exploring a vast parametric space encompassing composition, milling parameters that govern microstructural features such as intraparticle voids and fuel-oxidizer mixing, and the resulting inhomogeneous shock reactivity of individual particles. To present our approach, we used a model composition 8Al⋅3CuO, previously optimized for combustion. We milled powders and prescreened different prepared batches using differential scanning calorimetry (DSC) to rule out batches with significant pre-reaction. Then …

Randomized controlled trials underpin evidence-based medicine, but a growing proportion of trials contain implausible, inaccurate, or fabricated data. When such studies are incorporated into systematic reviews, they distort effect estimates, inflate evidence certainty, and can mislead the guideline recommendations that the reviews aim to inform. Within 8 recent American Academy of Allergy, Asthma & Immunology and American College of Allergy, Asthma and Immunology Joint Task Force on Practice Parameters (JTFPP) systematic reviews, 17% of trials published between 2021 and 2024 were problematic, and in a network meta-analysis of antihistamines for chronic urticaria, 39% of recent trials were excluded because of …

Leveraging Persistent L-Band Leo-To-Geo Relays For The Orchestration Of High-Bandwidth Optical Inter-Satellite Links, Jonathan Maier, Skylar A. Cox

Small Satellite Conference

As the already tremendous demand for data transfer in Low Earth Orbit (LEO) grows, Free-Space Optical (FSO) communication has emerged as a critical capability due to high data rates and inherent resilience attributes. However, the operational complexity of FSO, specifically the Pointing, Acquisition, and Tracking (PAT) process, requires significant operational planning. The narrow beamwidth of optical terminals requires precise spatial coordination, resulting in latency during link establishment, heavy reliance on scheduled ground-based commanding, and an impediment to agile, responsive, and ad hoc operations.

This paper presents a novel orchestration architecture utilizing Viasat’s L-band space relay network as a persistent, always-on …

Evaluating Performance Of Hardware-Accelerated Vessel Detection Algorithms, Michael Tietz, John Warner, Quinton Davidson, Douglas Carssow

Small Satellite Conference

Earth observing satellites contribute to the monitoring of maritime activity by enabling large-scale coverage of open water. For example, spacecraft data can be used to monitor and combat Illegal, Unreported, and Unregulated (IUU) fishing that occurs in coastal and international waters across the globe. However, information latencies limit the utility of space-based sensors for operational users who need real-time situational awareness. These limitations are especially pronounced for small spacecraft with limited power generation and downlink capabilities. In recent years, the devices and tools that enable edge computing and near real-time downlink from small spacecraft have improved substantially. Equipped with these …

Dynaband: Context-Aware Dynamic Band Selection For Onboard Hyperspectral Processing In Small Satellites, Rishigesh Jayananth, Brasen Sheeh

Small Satellite Conference

Hyperspectral small satellites now collect far more data than they can return to the ground. A single acquisition spans tens to hundreds of spectral bands, yet the downlink window on one pass carries only a fraction of it, so operators are forced to drop scenes, bin bands coarsely, or store data that never reaches the ground. Much of this waste is avoidable. When the task is known before the spacecraft images, whether to map water, monitor vegetation, or pick out a mineral signature, only a handful of bands actually carry the answer; the rest is paid for in downlink and …

Metadata-Conditioned Dark-Frame Modelling And Hsdr-Scanfusion Denoising: A Physics-Informed Independent Tool For Low-Cost Hyperspectral Small-Satellite Calibration, Nooh Adnan, Kyaw Thiha, Raffael Gil Dela Cruz, Li Cheng Zheng, Faijul Amin, Areeba Khan, Sameha Tasnim, Sung Jegal, Yunhan Bao, Iliya Shofman

Small Satellite Conference

Hyperspectral imaging in the shortwave-infrared spectrum is valuable for orbital Earth observation, but its use on low-cost, resource-constrained small satellites is limited by thermally dependent dark current, fixed-pattern noise, and intermittent access to matched calibration frames. Traditional mitigation through active cooling, shutters, or frequent dark-frame acquisition can be difficult to accommodate within small-satellite mass, power, volume, and operations budgets. This paper presents a physics-informed independent calibration tool that reconstructs condition-matched dark response from acquisition metadata rather than relying on hardware-heavy calibration at every operating point. The framework combines a stochastic dark-noise simulator, a metadata-conditioned neural dark operator that predicts spectral-spatial …

The ATA is constructed using 3D Ultrasonic Additive Manufacturing to co-fabricate the internal thermal transport channels and structural members, enabling direct integration of heat exchangers and fluid pathways within primary spacecraft components. The resulting architecture reduces mechanical interfaces, improves thermal transfer, and …

Development Of Wavelength-Division-Multiplexed All-Optical Relays For Low-Earth Orbit Free-Space Optical Communication Networks, Travis Jones, Justin Cook, Chris Krush, Doruk Engin, Keith G. Petrillo

Small Satellite Conference

In this work, we designed, built, and tested an all-optical relay amplifier to enable a space-based all-optical backbone for laser communications networks. The design sought to optimize links for LEO-based networks incorporating appropriate span lengths and optical terminal specifications. We incorporate an add-drop multiplexer for rerouting signals and designed the system to be flexible over span lengths with a nominal range of 1,800 km. We performed several tests of the nominally 60 dB gain amplifier to assess link dynamics unique to free space optical communications (FSOC) including the impact of pointing jitter, nonlinearities, gain flattening, and wide-band filters on an …

Delay/ Disruption Tolerant Networking In Cislunar Space, Sara Garcia-Beech, Rebecca Besser, Elizabeth Geist, Theresa Beech, Mike Palsson, Krishnan Narayanan, Ben Anderson

DTN is a network architecture composed of several different protocols that are designed to provide internetworking functionality and standardized multi-hop, end-to-end data delivery in highly stressed environments that are not optimal for traditional Internet Protocols. Bundle Protocol (BP) version 7, a store-and-forward protocol intended to run at the application layer on top of convergence layer protocols, provides the key delay tolerance functionality of DTN and is designed to handle intermittent …

Event-Driven Spacecraft Operations Demonstrated On Mms, Miles Bengtson, Alexander Barrie, Joseph Patton, Liam Greenlee, Paul Wood, Marcus Piquette, Russell Bjella, Matthew Chang, Joshua Paul

Small Satellite Conference

Operations engineers face the challenging task of capturing high-value science data while maintaining spacecraft health and functionality and responding to a dynamic space environment using limited information. This task is becoming increasingly complex as missions involve increasingly large numbers of spacecraft, target more elusive science signatures, and operate under growing budget and staffing constraints. Conventional pre-programmed time-sequence commands become increasingly burdensome for multi-spacecraft missions and are fundamentally incapable of reacting to rare, transient science events in real time.

To address this challenge, we have developed MEDOS: the Module for Event-Driven Operations of Spacecraft. Unlike machine learning and neural-network approaches, MEDOS …

Let’S Give The Fsck Up On Secded, Heather M. Quinn, Andrew Pineda, Gary Swift

Small Satellite Conference

Many space systems use error correcting codes (ECC) for handling radiation-induced upsets in memories. The most used ECCs are Hamming and Hsaio, which are single-error correction/double-error detection (SECDED) codes. The widespread use of these codes can lead to a dangerous overestimation of system reliability. Instead these codes are one of the best documented methods for microprocessor-based system crashes, due to uncorrectable faults. Less well documented is how these codes can lead to silent data corruption caused by miscorrections, where multiple errors are detected as a single error and corrected erroneously.

ECCs have always been sensitive to time-dependent errors, where SEUs …

Design And Qualification Of A Compact, Deployable Dual-Monopole Antenna System For Remote Sensing Microsatellites, Alexander J. Murphy, Bryan Johnston-Lemke, Robert E. Zee

Small Satellite Conference

Spacecraft conducting signals intelligence (SIGINT) missions require highly capable radio-frequency (RF) payloads. While the larger 80 kg-class platforms offer increased payload capacities, strict internal volume limitations persist. These constraints sometimes require stowing instruments, such as the dual-monopole Very High Frequency (VHF) antenna presented in this work, directly beneath the solar wings. This requirement has imposed a strict height constraint on the VHF antenna, mandating a highly compact and reliable deployment mechanism that avoids snagging or jamming during deployment. 

This paper presents the mechanism design and qualification test plan of a novel, deployable dual-monopole VHF antenna system designed to increase satellite …

Recovery Of Grus-1e From Magnetic Torquer Loss Using Data-Driven Open-Loop Attitude Steering, Nader Ganaba, Takanori Iwata, Minoru Kurata

Small Satellite Conference

In typical low Earth orbit (LEO) operations, the inability to remove excess angular momentum often leads to the decommissioning of a satellite. This paper presents the on-orbit recovery of GRUS-1E, a hundred kg class Earth observation satellite in Axelspace Corporation’s GRUS-1 constellation. The recovery followed the permanent loss of magnetic torquer commanding capability, which in turn disabled the satellite’s nominal reaction wheel momentum unloading. In addition, the satellite experienced persistent disturbance torques that significantly exceeded the combined contributions predicted by standard models, including gravity gradient, solar radiation pressure, aerodynamic drag, and the estimated residual magnetic dipole moment. The magnitude of …
