Bio-upcycling of even and uneven medium-chain-length diols and dicarboxylates to polyhydroxyalkanoates using engineered Pseudomonas putida.

Bio-upcycling of plastics is an emerging alternative process that focuses on extracting value from a wide range of plastic waste streams. Such streams are typically too contaminated to be effectively processed using traditional recycling technologies. Medium-chain-length (mcl) diols and dicarboxylates (DCA) are major products of chemically or enzymatically depolymerized plastics, such as polyesters or polyethers.

Emergency Response Person Localization and Vital Sign Estimation Using a Semi-Autonomous Robot Mounted SFCW Radar.

The large number and scale of natural and man-made disasters have led to an urgent demand for technologies that enhance the safety and efficiency of search and rescue teams. Semi-autonomous rescue robots are beneficial, especially when searching inaccessible terrains, or dangerous environments, such as collapsed infrastructures. For search and rescue missions in degraded visual conditions or non-line of sight scenarios, radar-based approaches may contribute to acquire valuable, and otherwise unavailable information.

Forgetting to Remember: The Impact of Post-traumatic Stress Disorder on Prospective and Retrospective Memory Performance.

Objective: We examined the impact of post-traumatic stress disorder (PTSD) on both prospective (PM) and retrospective (RM) memory performance among a cross-sectional veteran sample.

Method: Data from tests of PM/RM memory and PTSD, anxiety, depression and sleep disturbance symptoms were examined among a prospectively recruited sample of 26 veterans with confirmed PTSD (PTSD+) and 26 well-matched, combat-exposed controls who did not meet criteria for PTSD (PTSD-).

Results: Small-to-moderate negative correlations emerged between PTSD symptom severity, visuospatial RM and some aspects of PM; general anxiety correlated more strongly with memory.

Psychometric properties of the late positive potential in combat-exposed veterans.

Trauma exposure is prevalent, associated with multiple forms of psychopathology, and thought to alter the neurobiological substrates of threat processing. The late positive potential (LPP) is an event-related potential (ERP) that may be a clinically useful probe of the neurobiology of threat processing. Despite evidence that combat-exposed veterans exhibit aberrant threat modulation of the LPP, no studies to date have tested the psychometric properties of the LPP in combat trauma-exposed, symptomatic veterans.

Concordance of Embedded Performance and Symptom Validity Tests and Associations with Mild Traumatic Brain Injury and Posttraumatic Stress Disorder among Post-9/11 Veterans.

Objective: The present study explored both embedded symptom (SVT) and performance (PVT) validity test scores within a post-9/11 veteran sample to elucidate the degree to which there is concordance between validity indicators, as well as how frequently one SVT and four PVT indicators were failed in screened mild traumatic brain injury (mTBI) and diagnosed posttraumatic stress disorder (PTSD).

Method: A total of 114 post-9/11 veterans were evaluated utilizing the Neurobehavioral Symptom Inventory (NSI) Validity-10, four embedded PVTs, mTBI screening, and a diagnostic interview for PTSD.

Results: While we found concordance between embedded PVTs and the NSI Validity-10 at select cutoffs (i.
