Ultralytics has spearheaded several U.S. Intelligence Community (IC) and Department of Defense (DoD) initiatives in the fields of particle physics, data science and artificial intelligence, as well as partnered with several universities, national labs, and privately held companies on a variety of efforts. Below are a sample of a few of these efforts past and present.
Electron Antineutrino Detection
Neutrinos provide a glimpse into some of the most obscured phenomena in high energy physics, but their precise nature and role in the universe remains a mystery. Almost 60 years after their first detection, neutrino research remains an active and fruitful pursuit in the fields of particle physics, astrophysics, and cosmology. In addition to nuclear reactors and the Sun, detected neutrino sources include particle accelerators, the atmosphere , core-collapse supernovae, the Earth, and most recently the cosmos.

LAPPD: Large Area Picosecond Photo-Detector
Incom, Inc., the University of Hawaii, and Ultralytics LLC are developing a large-area system to measure the time-of-arrival of relativistic particles with picosecond resolution. These are respectively a factor of 100 and 20 better than the present state-of-the-art. This would involve development in a number of intellectually challenging areas: three-dimensional modeling of photo-optical devices, the design and construction of fast, economical, low-power electronics, the `end-to-end' (i.e. complete) simulation of large systems, real-time image processing and reconstruction, and the optimization of large detector and analysis systems for medical imaging.

The mTC is a plastic 0.2% 10B–doped scintillator 13 × 13 × 13 cm3 cube surrounded by 24 8×8 Micro-Channel Plate (MCP) photon detectors totaling 1536 individual channels/pixels. It uses custom-made electronics mounted directly to light-sensing MCPs, providing for a compact detector capable of robust particle ID and realtime noise rejection. As a novel design with unprecedented spatial and temporal resolution, this detector will be able to determine particle directions beyond previous capabilities, including electron antineutrino detection, as well as gamma and neutron imaging.

SFM: Structure From Motion
Traditional Structure From Motion (SFM) techniques may be extended to the GPS/INS systems found in most of today's small aerial UAVs. Ultralytics specializes in processing Full Motion Video (FMV) from these platforms for the purposes of extracting real-time Digital Elevation Models (DEMs).

Neutron and Gamma (γ) Detection
Neutron and gamma detection via organic scintillator coupled to Silicon PhotoMultipliers (SiPMs) is a promising new direction in the fields of radiation safety and medical imaging. Precise kinematic reconstruction of the neutron path through the detector allows for a robust probability mapping onto the sky of the original incoming neutron direction. Potential applications include radiation safety at nuclear power plants, cosmic-ray induced neutron background mapping, border security, and nuclear nonproliferation efforts.
