Free Cognitive Capacity Assessed by the P300 Method During Manual Docking Training in Space.

The classical P300 brain potential method was used to assess the cognitive capacity during training of manual docking in space. The aim of the study was to enhance the safety of this operation during a mission. To examine this, = 8 cosmonauts had to perform the manually controlled docking task simultaneously with an acoustic monitoring task.

Controlled Swelling of Monolithic Films as a Facile Approach to the Synthesis of UHMWPE Membranes.

A new method of fabricating porous membranes based on ultra-high molecular weight polyethylene (UHMWPE) by controlled swelling of the dense film was proposed and successfully utilized. The principle of this method is based on the swelling of non-porous UHMWPE film in organic solvent at elevated temperatures, followed by its cooling and further extraction of organic solvent, resulting in the formation of the porous membrane. In this work, we used commercial UHMWPE film (thickness 155 μm) and o-xylene as a solvent.

The effect of PbS quantum dots on molecular dynamics and conductivity of PTB7:PC71BM bulk heterojunction as revealed by dielectric spectroscopy.

A ternary photovoltaic blend containing the PTB7 donor component, the PC71BM acceptor component, and colloidal quantum dots of lead sulfide (PbS QDs) was investigated using broadband dielectric spectroscopy. In the dielectric loss spectrum of PTB7:PC71BM:PbS QDs, γ- and β-relaxation processes in PTB7 were recognized and analyzed in terms of Arrhenius-type equations. To elucidate the effect of PbS QDs on molecular dynamics of PTB7, the activation energies of both processes were evaluated and compared with those obtained for the binary PTB7:PC71BM blend.

Operator's Reliability During Spacecraft Docking Training on Board Mir and ISS.

The experimental research PILOT on board the space stations aimed to assess cosmonauts expectable reliability in a mission relevant operation, the manual docking of Soyuz or Progress spacecrafts on the space stations Mir and International Space Station (ISS), respectively. Therefore, a simulation of the docking of two space apparatuses was used for training and research. The methodological approach is described, taking into consideration the level of performance and the individual effort spent, the psychophysiological costs.

Long-Term Follow-Up of a Randomized Trial of Supported Employment for SSDI Beneficiaries With Mental Illness.

Objective: In this study, the authors assessed the long-term impact of the Mental Health Treatment Study (MHTS), a randomized controlled trial testing the effects of providing 2 years of employment services based on the evidence-based individualized placement and support model to Social Security Disability Insurance (SSDI) recipients with serious mental illness. Treatment recipients also received systematic medication management, supplemental health care supports, and short-term relief from medical continuing disability review by the Social Security Administration (SSA).

Methods: MHTS site data for 2,160 participants were linked to SSA administrative data from 2011 to 2015, 1 to 5 years after the original study concluded.
