Training image-based reinforcement learning (RL) agents are sample-inefficient, limiting their effectiveness in real-world manipulation tasks. Sim2Real, which involves training simulations and transferring to the real world, effectively reduces dependence on data. However, performance of transferred agent degrades due visual difference between two environments. This research presents a low-cost...

There has been a plethora of studies on domain wall dynamics in magnetic nanostrips, mainly because its versatile non-linear physics and potential applications data storage devices. However, most the focus out-of-plane walls or in-plane head-to-head (tail-to-tail) walls. Here, we numerically study field-driven side-by-side ferromagnetic strips, which can be stable presence an easy-axis anisotro...

[Purpose] The purpose of this study was to investigate the effect of neck flexion restriction on sternocleidomastoid (SCM), rectus abdominis (RA), and external oblique (EO) muscle activity during a traditional curl-up exercise and a curl-up with neck flexion restriction. [Subjects] In total, 13 healthy male subjects volunteered for this study. [Methods] All subjects performed a traditional curl...

The nomenclature of papaya viruses has been a source of confusion, primarily because symptomatology has been used extensively for describing papaya viruses. Although the literature is confusing and causal viruses for each of the diseases are not well identified, it appears that papaya viral diseases can generally be grouped as ring spot, mosaic and leaf curl, associated with poty, potex and gem...

This paper describes the testing of Profiled Steel Sheet Dry Board (PSSDB) load bearing wall system. Experimental tests were conducted on various PSSDB wall samples, with and without infill materials to study its effect on the PSSDB load bearing wall performance. A proprietary profiled steel sheet, Ajiya Cliplock (0.48 mm thick) attached to Cemboard (10 mm thick) on one side, and Cemplank (10 m...

The objective of this pilot study was to determine the effect of 6 different abdominal exercises on the electrical activity of the upper rectus abdominis (URA) and lower rectus abdominis (LRA). Eight healthy, adult volunteers completed 6 random abdominal exercises: curl up, Sissel ball curl up, Ab Trainer curl up, leg lowering, Sissel ball roll out, and reverse curl up. Action potentials were r...
