- Wing rapid responses and aerodynamics of fruit flies during headwind gust perturbations 6. July 2020Insects are the main source of inspiration for flapping-wing micro air vehicles (FWMAVs). They frequently encounter wind gust perturbations in natural environments, and effectively cope with these perturbations. Here, we investigated the rapid gust response of flies to instruct the gust stability design of FWMAVs. A novel method to produce impulsive wind gusts that lasted […]Mancang Gu, Jianghao Wu and Yanlai Zhang
- Longitudinal mode model-based controller design for tailless flapping wing robot with loop shaping
compensator 6. July 2020In this study, the stable proportional–derivative (PD) controller gains for pitch control (longitudinal control) are obtained using the linearized and non-coupled longitudinal-mode flight dynamics model of the tailless, hover-capable, flapping wing robot named KUBeetle. To acquire a more realistic longitudinal model of KUBeetle, we incorporated the dynamics of the sensors, filters, and servo. Then, the […]Steven Aurecianus, Hoang Vu Phan, Taesam Kang and Hoon Cheol Park
- Body torsional flexibility effects on stability during trotting and pacing based on a simple
analytical model 6. July 2020Quadruped animals use not only their legs but also their trunks during walking and running. Although many previous studies have investigated the flexion, extension, and lateral bending of the trunk, few studies have investigated the body torsion, and its dynamic effects on locomotion thus remain unclear. In this study, we investigated the effects of body […]Mau Adachi, Shinya Aoi, Tomoya Kamimura, Kazuo Tsuchiya and Fumitoshi Matsuno
- Architecture of a catalytically active homotrimeric plant cellulose synthase complex 9. July 2020Cellulose is an essential plant cell wall component and represents the most abundant biopolymer on Earth. Supramolecular plant cellulose synthase complexes organize multiple linear glucose polymers into microfibrils as load-bearing wall components. We determined the structure of a poplar cellulose synthase CesA homotrimer that suggests a molecular basis for cellulose microfibril formation. This complex, stabilized […]Purushotham, P., Ho, R., Zimmer, J.
- Primary exposure to SARS-CoV-2 protects against reinfection in rhesus macaques 2. July 2020Coronavirus disease 2019 (COVID-19), which is caused by infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has become a global pandemic. It currently remains unclear whether convalescing patients have a risk of reinfection. We generated a rhesus macaque model of SARS-CoV-2 infection that was characterized by interstitial pneumonia and systemic viral dissemination mainly […]Deng, W., Bao, L., Liu, J., Xiao, C., Liu, J., Xue, J., Lv, Q., Qi, F., Gao, H., Yu, P., Xu, Y., Qu, Y., Li, F., Xiang, Z., Yu, H., Gong, S., Liu, M., Wang, G., Wang, S., Song, Z., Liu, Y., Zhao, W., Han, Y., Zhao, L., Liu, X., Wei, Q., Qin, C.
- Architecture and function of human uromodulin filaments in urinary tract infections 2. July 2020Uromodulin is the most abundant protein in human urine and forms filaments that antagonize the adhesion of uropathogens; however, filament structure and mechanism of protection remain poorly understood. We used cryo-electron tomography to show that the uromodulin filament consists of a zigzag-shaped backbone with laterally protruding arms. N-glycosylation mapping and biophysical assays revealed that uromodulin […]Weiss, G. L., Stanisich, J. J., Sauer, M. M., Lin, C.-W., Eras, J., Zyla, D.

- Daily briefing: Genetic evidence of Native American ancestry among Polynesian people 9. July 2020Nature, Published online: 09 July 2020; doi:10.1038/d41586-020-02078-xPeople from Polynesia and South America mingled around 800 years ago — though it’s not clear who visited whom. Plus: mounting evidence suggests coronavirus is airborne, and precise gene edits made to mitochondrial DNA for the first time.Flora Graham
