Advanced concentrator panels
The prototype fabrication of a lightweight, high-quality cellular glass substrate reflective panel for use in an advanced point-focusing solar concentrator was completed. The reflective panel is a gore shaped segment of an 11-m paraboloidal dish. The overall concentrator design and the design of the reflective panels are described. prototype-specific panel design modifications are discussed and the fabrication approach and procedure outlined
Advanced solar concentrator mass production, operation, and maintenance cost assessment
The object of this assessment was to estimate the costs of the preliminary design at: production rates of 100 to 1,000,000 concentrators per year; concentrators per aperture diameters of 5, 10, 11, and 15 meters; and various receiver/power conversion package weights. The design of the cellular glass substrate Advanced Solar Concentrator is presented. The concentrator is an 11 meter diameter, two axis tracking, parabolic dish solar concentrator. The reflective surface of this design consists of inner and outer groups of mirror glass/cellular glass gores

Four days of mindfulness meditation training for graduate students: A pilot study examining effects on mindfulness, self-regulation, and executive function
Self-regulation facilitates coping with academic stress and demands. This pilot study examined the effects of four consecutive mindfulness meditation classes on self-regulation and executive function in graduate students. Self-report measures of mindfulness, self-regulation, and executive functions were completed before and after the mindfulness classes. Paired t-tests compared pre-post training scores and effect sizes were calculated using Cohen’s d. A sample of 8 psychology graduate students (7 female) volunteered to participate in the mindfulness training. The group classes were modeled after meditation practices in Mindfulness-Based Cognitive Therapy. Each class involved a specific theme: (1) Stepping Out of Automatic Pilot, (2) Awareness of the Breath, Body, Sounds, and Thoughts, (3) Mindful Movement, and (4) Working with Difficulty. Students significantly improved in mindfulness and self-regulation skills. Large effects were obtained for increases in total mindfulness, and the mindfulness facets of acting with awareness and non-reactivity to inner experiences. Additionally, large effects were calculated for total self-regulation and the self-regulatory facet of self-reinforcement. The current pilot study provides preliminary support for cultivating mindfulness skills and enhancing self-regulatory capacity in graduate students through four consecutive days of mindfulness training

Real-time phase-shift detection of the surface plasmon resonance
We investigate a method to directly measure the phase of a laser beam
reflected from a metallic film after excitation of surface plasmon polaritons.
This method permits real time access to the phase information, it increases the
possible speed of data acquisition, and it may thus prove useful for increasing
the sensitivity of surface plasmon based sensors
Mobile technology offers novel insights into the control and treatment of allergic rhinitis : The MASK study
Background: Mobile health can be used to generate innovative insights into optimizing treatment to improve allergic rhinitis (AR) control. Objectives: A cross-sectional real-world observational study was undertaken in 22 countries to complement a pilot study and provide novel information on medication use, disease control, and work productivity in the everyday life of patients with AR. Methods: A mobile phone app (Allergy Diary, which is freely available on Google Play and Apple stores) was used to collect the data of daily visual analogue scale (VAS) scores for (1) overall allergic symptoms; (2) nasal, ocular, and asthma symptoms; (3) work; and (4) medication use by using a treatment scroll list including all allergy medications (prescribed and over-the-counter) customized for 22 countries. The 4 most common intranasal medications containing intranasal corticosteroids and 8 oral H-1-antihistamines were studied. Results: Nine thousand one hundred twenty-two users filled in 112,054 days of VASs in 2016 and 2017. Assessment of days was informative. Control of days with rhinitis differed between no (best control), single (good control for intranasal corticosteroid-treated days), or multiple (worst control) treatments. Users with the worst control increased the range of treatments being used. The same trend was found for asthma, eye symptoms, and work productivity. Differences between oral H-1-antihistamines were found. Conclusions: This study confirms the usefulness of the Allergy Diary in accessing and assessing behavior in patients with AR. This observational study using a very simple assessment tool (VAS) on a mobile phone had the potential to answer questions previously thought infeasible.Peer reviewe
Does the 1/f frequency-scaling of brain signals reflect self-organized critical states?
Many complex systems display self-organized critical states characterized by
1/f frequency scaling of power spectra. Global variables such as the
electroencephalogram, scale as 1/f, which could be the sign of self-organized
critical states in neuronal activity. By analyzing simultaneous recordings of
global and neuronal activities, we confirm the 1/f scaling of global variables
for selected frequency bands, but show that neuronal activity is not consistent
with critical states. We propose a model of 1/f scaling which does not rely on
critical states, and which is testable experimentally.Comment: 3 figures, 6 page
