Characterising cerebral haemodynamic oscillations during running

Running involves repetitive foot-strikes that induces a ‘beat phenomenon’, identified as a summation of two pressure waves that result in periodic pulse pressure oscillations. To date, only one study has examined this phenomenon to investigate how it affects cerebral blood flow (CBF) responses, reporting that blood pressure oscillations are reflected in CBF (as indexed by middle cerebral artery blood velocity, MCAv). Based on this work, we tested the hypothesis that altering the heel-strike force would impact the amplitude, frequency and duration of MCAv oscillations. Ten participants completed four exercise sessions: a treadmill maximal oxygen consumption test (i.e. VO2peak), followed by a randomised crossover design of three submaximal exercise sessions: (i) gradient running protocol; (ii) step frequency and foot-strike running protocol, and (iii) 30-minute cycling 65% VO2peak protocol. Oscillations were present during each running protocol with a variety of oscillatory patterns occurring between participants and between different gradients, running styles and step frequencies. No statistical difference in the oscillatory pattern occurred between submaximal treadmill running protocols (p>.05), while no MCAv oscillations were present during cycling. Data collectively demonstrated that altering the heel-strike force during running affects the oscillatory pattern in MCAv, albeit not statistically supported from this small sample size

Pengaruh Dukungan Keluarga dan Motivasi Berwirausaha terhadap Kesejahteraan Keluarga dengan Kinerja Usaha Mompreneur sebagai Variabel Intervening

Tujuan penelitian ini adalah untuk menguji variabel kinerja usaha mompreneur sebagai mediasi dukungan keluarga dan motivasi berwirausaha terhadap kesejahteraan keluarga. Penelitian ini melibatkan 125 mompreneur yang diperoleh dengan cara menyebarkan kuesioner secara offline. Hasil yang diperoleh dianalisis menggunakan SPSS versi 26 dan kalkulator Sobel Test. Hasil menunjukkan bahwa dukungan keluarga dan motivasi berwirausaha berpengaruh positif terhadap kinerja usaha mompreneur dan kesejahteraan keluarga, selain itu kinerja usaha mompreneur juga memediasi pengaruh dukungan keluarga dan motivasi berwirausaha terhadap kesejahteraan keluarga. Penelitian ini memberikan implikasi teoritis bagi pengembangan teori kewirausahaan dengan menekankan pentingnya dukungan keluarga dan motivasi berwirausaha dalam meningkatkan kinerja usaha dan kesejahteraan keluarga. Implikasi praktisnya adalah perlunya program pelatihan kewirausahaan untuk meningkatkan motivasi dan kinerja usaha mompreneur.The purpose of this study is to examine the role of mompreneurs' business performance as a mediator between family support and entrepreneurial motivation on family welfare. This research involved 125 mompreneurs obtained by distributing offline questionnaires. The results were analyzed using SPSS version 26 and the Sobel Test calculator. The findings indicate that family support and entrepreneurial motivation have a positive influence on mompreneurs' business performance and family welfare. Additionally, mompreneurs' business performance mediates the influence of family support and entrepreneurial motivation on family welfare. This study provides theoretical implications for the development of entrepreneurship theory by emphasizing the importance of family support and entrepreneurial motivation in improving business performance and family welfare. The practical implication is the need for entrepreneurship training programs to enhance mompreneurs' motivation and business performance

Ratioless full-complementary 12-transistor static random access memory for ultra low supply voltage operation

In this study, a ratioless full-complementary 12-transistor static random access memory (SRAM) was developed and measured to evaluate its operation under an ultra low supply voltage range. The ratioless SRAM design concept enables a memory cell design that is free from the consideration of the static noise margin (SNM). Furthermore, it enables a SRAM function without the restriction of transistor parameter (W/L) settings and the dependence on the variability of device characteristics. The test chips that include both conventional 6-transistor SRAM cells and the ratioless full-complementary 12-transistor SRAM cells were developed by a 180 nm CMOS process to compare their stable operations under an ultralow supply voltage condition. The measured results show that the ratioless full-complementary 12-transistor SRAM has superior immunity to device variability, and its inherent operating ability at the supply voltage of 0.22 V was experimentally confirmed

Vth-Shiftable SRAM Cell TEGs for Direct Measurement for the immunity of the Threshold Voltage Variability

We developed VTSTs for 6T-SRAM and RL-SRAM and evaluated them to investigate the influences of SRAM operation by Vth fluctuation using measured FCMs and CΔVths. As a result, we successfully confirmed the superior immunity of Vth fluctuation of the RL-SRAM than the 6T-SRAM.IEEE International Conference on Microelectronic Test Structures (ICMTS 2017), 27-30 March 2017, Grenoble, Franc
