- Enhancing propulsion performance of a flexible heaving foil through dynamically adjusting its
flexibility 10. October 2019This study investigates how dynamically adjusting the bending stiffness of a heaving foil affects its propulsion performance in a flow of Reynolds number 200. The foil is forced to oscillate sinusoidally at the leading edge, and its bending stiffness is tuned in a square-wave manner. Such a fluid-structure interaction (FSI) problem is explored using an […]Chenglei Wang, Feng Ren and Hui Tang
- A bio-inspired self-propelling endoscopic device for inspecting the large intestine 10. October 2019This article presents an inchworm-inspired, pneumatic, endoscopic device intended to navigate inside a colon. The device consists of a propulsion segment with two linear balloons and two gripper segments with four twisted balloons. The three segments can be sequentially actuated by pressurized air, which achieves a propulsive motion like an inchworm. Experimental results of the […]Zhiwei Chen, Jianbin Liu, Shuxin Wang and Siyang Zuo
- Bioinspired magnetoreception and navigation in nonorthogonal environments using magnetic signatures 23. September 2019Diverse taxa use Earth’s magnetic field in conjunction with other sensory modalities to accomplish navigation tasks ranging from local homing to long-distance migration across continents and ocean basins. However, despite extensive research, the mechanisms that underlie animal magnetoreception are not clearly understood, and how animals use Earth’s magnetic field to navigate is an active area […]Brian K Taylor and Sabrina Corbin

- Structural basis for the docking of mTORC1 on the lysosomal surface 10. October 2019The mTORC1 protein kinase regulates growth in response to nutrients and growth factors. Nutrients promote its translocation to the lysosomal surface, where its Raptor subunit interacts with the Rag GTPase-Ragulator complex. Nutrients switch the heterodimeric Rag GTPases between four different nucleotide binding states, only one of which (RagA/B•GTP–RagC/D•GDP) permits mTORC1 association. We determined the structure […]Rogala, K. B., Gu, X., Kedir, J. F., Abu-Remaileh, M., Bianchi, L. F., Bottino, A. M. S., Dueholm, R., Niehaus, A., Overwijn, D., Fils, A.-C. P., Zhou, S.

- Genetic regulatory variation in populations informs transcriptome analysis in rare disease 10. October 2019Transcriptome data can facilitate the interpretation of the effects of rare genetic variants. Here, we introduce ANEVA (analysis of expression variation) to quantify genetic variation in gene dosage from allelic expression (AE) data in a population. Application of ANEVA to the Genotype-Tissues Expression (GTEx) data showed that this variance estimate is robust and correlated with […]Mohammadi, P., Castel, S. E., Cummings, B. B., Einson, J., Sousa, C., Hoffman, P., Donkervoort, S., Jiang, Z., Mohassel, P., Foley, A. R., Wheeler, H. E., Im, H. K., Bonnemann, C. G., MacArthur, D. G., Lappalainen, T.
- Grand challenges in the science of wind energy 10. October 2019Harvested by advanced technical systems honed over decades of research and development, wind energy has become a mainstream energy resource. However, continued innovation is needed to realize the potential of wind to serve global demand for clean energy. Here, we outline three interdependent, cross-disciplinary grand challenges underpinning this research endeavor. The first is the need […]Veers, P., Dykes, K., Lantz, E., Barth, S., Bottasso, C. L., Carlson, O., Clifton, A., Green, J., Green, P., Holttinen, H., Laird, D., Lehtomäki, V., Lundquist, J.
