This week’s Question: A new study published from the Policy Insights from the Behavioral and Brain Sciences found action video games—which require players to navigate complex 3D settings, account for quick-moving targets, and switch between focused and distributed attention—are most beneficial to cognitive...

The ability to monitor and detect microorganism contamination/infection is important for long space voyages, in order to maintain a clean environment not only for the health of the astronauts, but also for electronics and structural materials....

A hyperbaric chamber has been designed to achieve the goals of maximizing safety, minimizing complexity, and minimizing cost of hyperbaric chamber therapy. This design minimizes the volume of compressed gas in the chamber, and eliminates the need for complex gas mixing, carbon dioxide scrubbing,...

Leukocytes respond to toxic, infectious, and inflammatory processes to defend tissues and eliminate disease process or toxic challenge. Accurate and prompt counting and differentiation of leukocytes is critical for diagnoses of infection, leukemia, or allergy;...

The ISS (International Space Station) Medical Operations Requirements Document (MORD) establishes the medical support requirements for ionizing radiation exposure, including common dose limits, radiation monitoring, recordkeeping, and management of radiation exposure...

This invention facilitates collection, storage, concentration, and drying of liquid or mixed liquid/solid waste material. The invention may serve as a portable toilet or may be used to dry biological specimens or concentrate water samples for analysis. It can replace diapers, special plastic bags, and airflow waste disposal...

A promising strategy of early diagnosis is the detection of biological signatures (molecular biomarkers) from readily available body fluids, such as blood. However, the onset of most human diseases cannot be univocally identified on the basis of a single biomarker....

CODE is a framework for control and observation in distributed environments. The framework enables the observation of resources (computer systems, storage systems, networks, and so on), services (database servers, application execution, servers, file transfer servers,...

Simple RunTime eXecutive (SRTX) software provides scheduling and publish/subscribe data transfer services. The scheduler allows dynamic allocation of real-time periodic and asynchronous tasks across homogeneous multi core/multiprocessor systems. Most real-time systems assign tasks to specific cores on an a priori...

Outlier or anomaly detection refers to the task of identifying abnormal or inconsistent patterns from a dataset. While they may seem to be undesirable entities, identifying them has many potential applications in fraud and intrusion detection, medical research, and safety-critical...

A report describes a self-stabilizing distributed clock synchronization protocol in the absence of faults in the system. It is focused on the distributed clock synchronization of an arbitrary, non-partitioned digraph ranging from fully connected to 1-connected...

This project investigated advanced navigation strategies required to approach, perform proximity operations, and return a sample from an asteroid or comet. An optimized navigation strategy for a notional mission to a near-Earth asteroid was developed to serve as...

The Orbit Determination Toolbox (ODTBX) 2012a (v5.0) is an advanced mission simulation and analysis tool used for concept exploration, proposal, early design phase, or rapid design center environments: the emphasis is on flexibility, but it has enough fidelity to produce credible results. ODTBX v5.0 includes...

Writing (recording) to a storage device and reading from it can be considered as a noisy channel. A storage device such as magnetic recoding and optical recording can be modeled as a partial response channel. Partial-response techniques are a special case of precoding technique where the...

This decision support system provides an integrated platform for assessing the quality of Spitzer scheduling options. The application aids in scheduling instrument selection, assigns schedule times to specific observation requests, and generates stored sequence products destined...

A software program enables a user to track a scene or a spot on Earth from space (such as from the ISS) using an innovative algorithm. This robust and highly accurate software allows a scene to be tracked that can be not only the shifted version of a previous scene,...

The task of producing Mars Science Laboratory (MSL) personnel schedules is daunting. Through automation, the labor and number of mistakes made are reduced when compared to the manual process. This software not only allows for common constraints to be expressed,...

Planning area coverage observations is a challenge in an architecture with a framing imager affixed to a bus that can be moved, and a mirror or other device that allows for small, but fast, observation of adjacent areas along the boresight of a telescope. The telescope boresight can slew slowly...

Apaper reports a method of converting distributed curvature measurements into a three-dimensional shape by combining elastic rod theory and differential geometry to arrive at a three-dimensional solution of the Frenet-Serret formulas. A new method of calculating the...

Low-Density Parity-Check (LDPC) codes are the best error-correcting codes known for a wide variety of communications applications. The AR4JA code family encompasses encoders and decoders for nine error-correcting codes. These include Accumulate, Repeat-by-4, and Jagged Accumulate (AR4JA) codes...

The prediction of a conserved scalar is important in many fields of study. For example, in modeling of combustion processes, if a conserved scalar exists, the mathematical problem can be greatly simplified. Inert gases transported in mixtures of other gases are also...

The Dictionary Management System (DMS) is a Web-based tool to develop and store a project command and telemetry dictionary. The dictionary defines a project’s flight/ground interface. In recent years, dictionaries have become very large, making it hard to maintain traditional methods of flat-file storage and manual...

Currently, there are no programmatic methods to query the NIST National Vulnerability Database (NVD) without downloading the entire database in XML format, parsing the content, loading the resulting data into a self-hosted database, and then developing an interface for querying the content. This tool...
