TL;DR: Significant findings include an appreciation for the role combat plays in the development of mental disorders, including PTSD and traumatic brain injury, and efforts to understand the determinants, prevention, recognition, and treatment of combat-related mental disorders.
Abstract: Although documentation that war infl icts psychological casualties dates back to the American Civil War and earlier, most research began after the Vietnam confl ict, when studies focused on post-traumatic stress disorder (PTSD). With ongoing confl icts in Iraq and Afghanistan, there has been signifi cant research to illuminate the epidemiology of war-related psychological casualties. Signifi cant fi ndings include an appreciation for the role combat plays in the development of mental disorders, including PTSD and traumatic brain injury (TBI). Recent research has endeavoured to understand and improve psychological resilience to temper potentially adverse mental health effects of military service in the theatre of combat operations. Over 2 million US service members have now deployed and returned over 3 million times to the Iraq and Afghanistan confl icts. Mental health providers in the Departments of Defense and Veterans Affairs healthcare systems have consequently observed steep increases in mental health service use among these personnel. The Departments have responded aggressively to bolster staffi ng levels, increase capacity, improve available services, and anticipate future needs. Scientists and clinicians continue efforts to understand the determinants, prevention, recognition, and treatment of combat-related mental disorders.

TL;DR: An all-fiber supercontinuum source that generates a continuous spectrum from 1.6 μm to >11 μm with 417 mW on-time average power at 33% duty cycle is demonstrated.
Abstract: We demonstrate an all-fiber supercontinuum source that generates a continuous spectrum from 1.6 μm to >11 μm with 417 mW on-time average power at 33% duty cycle. By utilizing a master oscillator power amplifier pump with three amplification stages and concatenating solid core ZBLAN, arsenic sulfide, and arsenic selenide fibers, we shift 1550 nm light to ∼4.5 μm, ∼6.5 μm, and >11 μm, respectively. With 69 mW past 7.5 μm, this source provides both high power and broad spectral expansion, while outputting a single fundamental mode.

TL;DR: In this paper, the authors combine Volterra theory and proper orthogonal decomposition (POD) into a hybrid methodology for reduced-order modeling of aeroelastic systems.
Abstract: This research combines Volterra theory and proper orthogonal decomposition (POD) into a hybrid methodology for reduced-order modeling of aeroelastic systems. The outcome of the method is a set of linear ordinary difierential equations (ODEs) describing the modal amplitudes associated with both the structural modes and the POD basis functions for the ∞uid. For this research, the structural modes are sine waves of varying frequency, and the Volterra-POD approach is applied to the ∞uid dynamics equations. The structural modes are treated as forcing terms which are impulsed as part of the ∞uid model realization. Using this approach, structural and ∞uid operators are coupled into a single aeroelastic operator. This coupling converts a free boundary ∞uid problem into an initial value problem, while preserving the parameter (or parameters) of interest for sensitivity analysis. The approach is applied to an elastic panel in supersonic cross ∞ow. The hybrid Volterra-POD approach provides a low-order ∞uid model in state-space form. The linear ∞uid model is tightly coupled with a nonlinear panel model using an implicit integration scheme. The resulting aeroelastic model provides correct limit-cycle oscillation prediction over a wide range of panel dynamic pressure values. Time integration of the reduced-order aeroelastic model is four orders of magnitude faster than the high-order solution procedure developed for this research using traditional ∞uid and structural solvers.

TL;DR: It is the view that human engineering should mean fitting the machine to the man and keeping him functioning with efficiency, safety, and without discomfort, in any environment.
Abstract: The term “human engineering” can mean many things to many men. The field is new and in flux, and the definitions published in the past few years remind one of John Godfrey Saxe’s poem about the six blind men of Indostan and their several descriptions of the elephant. IVitliout arguing the merits of any of these definitions, and to achieve common understanding, i f not agreement, I shall simply state my view that human engineering should mean fitting the machine to the man and keeping him functioning with efficiency, uith safety, and without discomfort, in any environment. From this genera1 standpoint, I shall present briefly the results of three unpublished studies in applied physical anthropology, each relating to different aspects of the human being. The first w i l l summarize the engineering use of the percentile curve as a tool to improve the sizing of work space, clothing, or personal equipment. The second will outline how the use of muscle-strength data can improve human safety arid ease of machine operation. The third will attempt an answer 10 the question, ‘Wha t happens to the huttotks when you sit on them?”
