Reticle Stage Actuation Concepts for High Acceleration Trajectories in Next-generation Photolithography Tools by Seaberg, Charles Byron

“…We are unable to control the dynamics of the contact during which the measured peak contact force of 150 N exceeds the planned amount by 80% and results in the payload bouncing off the actuator. The second actuation concept we consider in theory is the use of dual-chamber pneumatic springs as energy storage devices to create turnaround forces for the long-stroke stage acceleration. …”

Discriminating quantum-optical beam-splitter channels with number-diagonal signal states: Applications to quantum reading and target detection by Nair, Ranjith

“…We consider the problem of distinguishing, with minimum probability of error, two optical beam-splitter channels with unequal complex-valued reflectivities using general quantum probe states entangled over M signal and M′ idler mode pairs of which the signal modes are bounced off the beam splitter while the idler modes are retained losslessly. …”

Geographical and Temporal Analysis of Tweets Related to COVID-19 and Cardiovascular Disease in the US by Xuan Zhang, Lan Mu, Donglan Zhang, Yuping Mao, Lu Shi, Janani Rajbhandari-Thapa, Zhuo Chen, Yan Li, José A. Pagán

“…The second wave of the pandemic caused another rise in the related tweets but not as much as the first one, as tweet frequency increased from February to April, decreased till June, and bounced back in July. At the regional level, four regions (Northeast, Midwest, North, and West) had the same trend of related tweets compared to the country as a whole. …”

An empirical study of the flag rugby game programme to promote gross motor skills and physical fitness in 5–6 year old preschool children by Zuozheng Shi, Xulin Yang, Xinru Zhang, Weihua Zhu, Yuxin Dai, Jian Li

“…An overall random sampling method was adopted to select 56 preschoolers aged 5–6 years from class A and class B,class A was the ExG (28) implemented a flag rugby games intervention program,and class B was the ConG (28) implemented a regular physical education program,with a 12-week intervention period.The content and requirements of the experimental intervention program were determined through a systematic analysis method, and the subjects' gross motor skills level was tested using the TGMD-3, and their physical fitness level was measured using China's fifth national physical fitness monitoring of early childhood (3–6 years) component.Experimental data were statistically analyzed using independent samples t-test, paired samples t-test, and repeated measures ANOVA test.After 12 weeks of practice, 1）We found that the ExG outperformed the ConG in Skip,One hand stationary dribble, Overhand throw, Underhand throw, Forehand strike of self-bounced,Kick a stationary ball, Total object control subject score, Total gross motor score test results with significant differences (p < 0.05).The ExG differed significantly (p < 0.01) in Grip strength, Stand long jump,Sit forward bend, Continuous jump on both feet,15 m obstacle run,Walk the balance beam, while the ConG differed significantly (p < 0.05) only in Continuous jump on both feet,15 m obstacle run and Stand long jump.2）We also found gender differences in gross motor skills and Physical fitness test results, this difference is manifested in boys outperformed girls in Total object control subject Score, Grip strength and 15 m obstacle run with significant difference (p < 0.05), girls outperformed boys in Sit forward bend with significant difference (p < 0.05).The 12-week flag rugby game programs improved gross motor skills and physical fitness levels of 5–6 year old preschoolers more comprehensively than the regular program, and we recommend the purposeful and organized promotion of a flag rugby game programs in the physical activity curriculum for 5–6 year old preschoolers.…”

Design, modeling, and predictive control of aerial physical interaction towards proactive maintenance by Kocer, Basaran Bahadir

“…The last challenge, posed by the interaction tool, comes from the sliding phase on the surface because bouncing occurs while it moves. In addition, ceiling effect where variable rotor wake degrades the performance of tracking predefined trajectory, and an unknown surface that must be included in the control algorithm and interaction tool design. …”
