1 This article will form part of a virtual special issue on advanced neutron scattering instrumentation, marking the 50th anniversary of the journal.QUOKKA is a 40 m pinhole small-angle neutron scattering instrument in routine user operation at the OPAL research reactor at the Australian Nuclear Science and Technology Organisation. Operating with a neutron velocity selector enabling variable wavelength, QUOKKA has an adjustable collimation system providing source-sample distances of up to 20 m. Following the largearea sample position, a two-dimensional 1 m 2 position-sensitive detector measures neutrons scattered from the sample over a secondary flight path of up to 20 m. Also offering incident beam polarization and analysis capability as well as lens focusing optics, QUOKKA has been designed as a general purpose SANS instrument to conduct research across a broad range of scientific disciplines, from structural biology to magnetism. As it has recently generated its first 100 publications through serving the needs of the domestic and international user communities, it is timely to detail a description of its asbuilt design, performance and operation as well as its scientific highlights. Scientific examples presented here reflect the Australian context, as do the industrial applications, many combined with innovative and unique sample environments. research papers J. Appl. Cryst.

[Purpose] The purpose of this study is to examine the effect of calf muscle massage on ankle flexibility and balance. [Subjects and Methods] The study’s subjects were 32 healthy college students, divided into two groups according to the massage methods applied. Both groups received five-minutes of massage to each calf, making a total of ten minutes. Massage group A received effleurage, tapotement and pressure, and massage group B received effleurage, friction and petrissage. The functional reaching test and the modified one leg standing test were performed to measure the flexibility and balance of the ankles both before and after the massage application. [Results] In the functional reaching test performed after the calf muscle massage intervention, both groups showed significant increases. However, no significant differences were found between the two groups. In the modified one leg standing test, massage group A showed a significant increase in flexibility and balance after the intervention only when the left foot was used for support. Massage group B showed a significant increase when each foot was used for support. A significant difference between the groups was only observed only when the left foot was used for support. [Conclusion] Calf muscle massage may be effective for enhancing the flexibility and balance function of the ankle joint. In particular, a combined application of friction and petrissage massage techniques may be more effective for increasing ankle joint flexibility. Therefore, the application of calf massage can be considered an appropriate method for improving balancing ability.

[Purpose] This study aimed to investigate the effects of McKenzie exercise, Kinesio taping, and myofascial release (MFR) on forward head posture (FHP). [Participants and Methods] Twenty-eight individuals with an FHP were enrolled. participants were randomly assigned to one of three groups: Group A, Group B and Group C. Group A underwent McKenzie exercise and MFR. Group B underwent McKenzie exercise and Kinesio taping. Group C underwent McKenzie exercise, MFR, and Kinesio taping. Interventions for all three groups were provided three times per week for four weeks. The acromion and tragus of ear (A-T length), craniovertebral angle (CVA), Cranial rotation angle (CRA), and neck disability index (NDI) were measured. [Results] The A-T length significantly differed after intervention in all three groups. CVA only significantly differed after intervention in group C. All three groups showed an increase in CRA after intervention; however, these increases were not statistically significant. [Conclusion] Considering these results, these three types of exercise may be recommended as effective exercises to improve posture in adults with FHP.

We have developed a high image quality OLED Display with motion blur reduction technology. Our latest work includes driving method which reduces motion blur using an adaptive black data insertion, brightness compensation technology, the simple structure pixel with low capacitance coupling for horizontal noise, and the multi-function integrated gate driver. The MPRT value of the OLED display panel with a fast response time was significantly affected by the frame frequency and the compensation driving method. The decrease in the MPRT value originated from the turning of the emitting pixels off in advance resulting from providing black data. The integrated gate drivers were designed to achieve the normal display, the black data insertion, and the compensation mode. The MPRT value of the 65inch UHD OLED panels was decreased to 3.4ms by using an integrated gate driver circuit. The motion blur of large-size OLED display panels was significantly reduced due to a decrease in the MPRT value.

[Purpose] The present study investigated the effect of manual lymph drainage (MLD) of the neck on electroencephalography (EEG) in subjects with psychological stress. [Methods] Twenty-six subjects were randomly allocated to receive one 15-min session of either MLD or resting on a bed (control). [Results] Analysis of EEG in the MLD group showed a significant increase in relaxation, manifested as an increase in average absolute and relative delta and alpha activity. [Conclusion] It is suggested that MLD provides acute neural effects that increase relaxation in subjects with psychological stress.
