We conducted a pilot study using a passive radio-wave-based home monitor in individuals with Parkinson disease (PD) with a focus on gait, home activity, and time in bed. We enrolled 7 ambulatory individuals to have the device installed in the bedroom of their homes over 8 weeks and performed standard PD assessments at baseline. We evaluated the abi...

Prior research has shown that various cues are exploited to reactively adjust attention, and such adjustments depend on learning associations between cues and proportion congruence. This raises the intriguing question of what will be learned when more than one cue is available, a question that has implications for understanding which cue(s) will d...
The authors examined the contrasting factors behind the distinct increases in hot days (HDs, daytime hot extremes) and warm nights (WNs, nighttime hot extremes) over land in the Northern Hemisphere during the boreal summers (June to August) of 1980?2018. While the occurrence of HDs has increased gradually since 1980, that of WNs increased abruptly ...
Disorder of doped conjugated polymers, which affects how effectively charge carriers are transported, is an important factor to be controlled to achieve high thermoelectric (TE) performance. However, experimentally controlling the disorder in highly doped polymers is difficult because of the limitations of dopant engineering. Here, by using a count...

The synthesis of metal oxides under basic conditions can yield unexpected experimental errors, such as contamination by impurities. Here, we clarified the influence of Si on the physicochemical properties of ZrO2 by comparing intentionally synthesized silica–zirconia (SZ) with accidentally synthesized Si-containing ZrO2. While pure monoclinic ZrO2 ...
Achieving cost-competitive catalysts with low Pt utilization and improving the durability caused by the corrosion of supports in the catalysts must be solved for the high activity in the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). Here, we show an innovative technique to synthesize unique nanotube supports for t...
CO2 hydrogenation to formic acid/formate is regarded as a promising strategy for achieving a sustainable circular-carbon economy. Herein, we report the catalytic behavior of nitrogen-doped carbon (NC)-immobilized ruthenium (RuCl3) catalysts for CO2 hydrogenation to formate. The NC supports were prepared at various temperatures by a facile one-step ...
Although the lean-NOx trap (LNT) has been used to reduce NOx emissions from diesel-powered vehicles, LNT application is limited because its performance degrades at low temperatures (e.g., during cold starting). Therefore, to enhance low-temperature NOx storage and adsorbent regeneration, γ-Al2O3 was coimpregnated with both Cu and Ba (Cu–Ba/γ-Al2O3)...
