Acute myeloid leukaemia (AML) is a haematologic malignancy with high relapse rates in both adults and children. Leukaemic stem cells (LSCs) are central to leukaemopoiesis, treatment response frequently associated measurable residual disease (MRD). However, the dynamics of LSCs within AML microenvironment not fully understood. This study utilized three-dimensional cellular automata (CA) modelling simulate LSC behaviour under induction chemotherapy. Our revealed: (i) correlation between...
An elastomer composite with controllable stiffness, known as a magnetorheological (MRE), is used in dynamic vibration absorber whose natural frequency tuned adaptively to the disturbance through application of an external magnetic field. The field-dependent property test fabricated MRE sample shows that stiffness changes by more than six times compared baseline value at 40% iron powder volume concentration. then fabricate frequency-tunable for mitigating transient vibrations...
In this research, a novel variable stiffness vibration isolator that uses magnetorheological elastomers (MREs) accompanied with fuzzy semiactive control was developed. Firstly, the viscoelastic characteristics of MREs in shear mode were clarified systematically order to achieve mathematical basis for controller development. Secondly, strategy based on Lyapunov theory and dynamic characteristic proposed minimizing movement isolator. conventional algorithm, command applied current MRE-based is...
Abstract. For most existing semiactive systems, it is commonly known that the stability and tracking performance will deteriorate in a real application due to input constraints nonlinearity system. In this study, order overcome above shortcomings, novel bench-scale suspension plant using magnetorheological elastomer (MRE)-based absorber accompanied with an adaptive global neural-network-based controller introduced. The neural network (ANN) used estimate uncertain dynamics of quarter-car...
Abstract Forward head posture (FHP) is a serious problem causing and neck disability, but the characteristics of muscle activity during long-term postural maintenance are unclear. This study aimed to investigate comparison electromyography (EMG) activation properties subjective fatigue between young adults with without habitual FHP. In this study, we examined changes in spatial temporal distribution patterns using high-density surface EMG (HD-SEMG) addition mean frequency, conventional...
Laparoscopic surgery is a representative operative method of minimally invasive surgery. However, most laparoscopic hand instruments consist rigid and straight structures, which have serious limitations such as interference by the limited field view endoscope. To improve flexibility dexterity these instruments, we propose new concept multijoint manipulator using variable stiffness mechanism. The uses magneto-rheological compound (MRC) whose rheological properties can be tuned an external...
Abstract Purpose The aim of this study was to examine the effect vibration on motor unit (MU) firing behavior and physical performance antagonist muscles in healthy young adult males. Methods Fourteen males (age = 24.3 ± 3.6 years) were included study. There two conditions, one which participants received 80 Hz distal tendon hamstring for 30 s control condition (no vibration). High-density surface electromyography (HD-SEMG) signals maximal voluntary contraction (MVC) knee extensor evaluated...
Two types of microwave filters, metallic powder filters and a filter using resistive coaxial cable, were tested. Attenuation the copper or stainless steel (SUS304L) was measured at 300 K, 77 4.2 it found that SUS304L nominal 30 /spl mu/m grain size gives best result as for single electron tunneling (SET) experiments. filter, Thermocoax with SMA connectors attached both ends is larger low temperatures than room temperatures, temperature dependence attenuation does not agree Zorin's model. The...
In general, the sound waves propagate spherically in free space, which accordingly makes global attenuation difficult. Using ordinary loudspeaker as a control source may cause interfered field with both attenuated and amplified regions. On other hand, recent development of high-directional loudspeakers based on new production theory known 'parametric array' has allowed transmission within narrow range acoustic space. present paper, numerical model parametric array quasi-linear approach...
To increase output power for piezoelectric vibration energy harvesters, considerable attention has recently been focused on a self-powered synchronized switch harvesting inductor (SSHI) technique employing an electrical and mechanical switch. However, there are two technical issues: in medium or highly coupled harvester, the coupling force, which increases as SSHI's voltage increases, will reduce harvester's displacement resulting power, few reports comparing performance of SSHI (ESS) (MSS)...
