    • Control and Function of Arm Swing in Human Walking and Running 

      Pontzer, Herman; Holloway, John H. III; Raichlen, David A.; Lieberman, Daniel Eric (The Company of Biologists, 2009)
      We investigated the control and function of arm swing in human walking and running to test the hypothesis that the arms act as passive mass dampers powered by movement of the lower body, rather than being actively driven ...

    • Control and local measurement of the spin chemical potential in a magnetic insulator 

      Du, Chunhui; van der Sar, Toeno; Zhou, Tony X.; Upadhyaya, Pramey; Casola, Francesco; Zhang, Huiliang; Onbasli, Mehmet C.; Ross, Caroline A.; Walsworth, Ronald; Tserkovnyak, Yaroslav; Yacoby, Amir (American Association for the Advancement of Science (AAAS), 2017-07-13)
      The spin chemical potential characterizes the tendency of spins to diffuse. Probing this quantity could provide insight into materials such as magnetic insulators and spin liquids and aid optimization of spintronic devices. ...

      Researchers have strived to develop lower limb wearable devices to improve the efficiency of human walking, however significant device inertia, kinematic constraints and the lack of optimal control strategies has limited ...

    • Control and raising passives, and why Mandarin does not smuggle 

      Liu, Na; Huang, C.-T. James James (Springer Nature, 2016)
      Collins (Syntax 8:81–120, 2005) proposes a smuggling approach to English passives that solves some problems associated with the traditional analysis. This article will show that while English passives involve smuggling, ...

    • Control of bacterial biofilm growth on surfaces by nanostructural mechanics and geometry 

      Epstein, A K; Hochbaum, A I; Kim, Philseok; Aizenberg, Joanna (IOP Publishing, 2011)
      Surface-associated communities of bacteria, called biofilms, pervade natural and anthropogenic environments. Mature biofilms are resistant to a wide range of antimicrobial treatments and therefore pose persistent pathogenic ...

    • Control of buckling in large micromembranes using engineered support structures 

      Iwase, Eiji; Hui, Pui-Chuen; Woolf, David; Rodriguez, Alejandro W.; Johnson, Steven G.; Capasso, Federico; Lončar, Marko (IOP Publishing, 2012)
      In this paper we describe a general method to avoid stress-induced buckling of thin and large freestanding membranes. We show that using properly designed supports, in the form of microbeams, we can reduce the out-of-plane ...

    • Control of Drosophila Courtship by Mating Drive 

      Zhang, Xingjie (2018-09-16)
      Most behaviors are not just actions and reactions, but are the result of self-evaluation and are the means of self-fulfillment. This means that the same external context (e.g. food) can hold different meaning to an animal ...

    • Control of Eukaryotic Transcription Elongation 

      Winston, Fred Marshall (BioMed Central, 2001)
      The Spt4, Spt5, and Spt6 proteins are conserved eukaryotic transcription-elongation factors. Recent studies have provided the first evidence that they are generally required in multicellular eukaryotes, including during ...

    • Control of Fire in the Paleolithic: Evaluating the Cooking Hypothesis 

      Wrangham, Richard (University of Chicago Press, 2017-08)
      According to current evidence, Homo sapiens was unable to survive on a diet of raw wild foods. Because cooked diets have large physiological and behavioral consequences, a critical question for understanding human evolution ...

    • Control of HIV-1C Replication Both in Vivo and in Vitro 

      Xie, Wen (2015-05-18)
      In this study, we established an HIV latency model using pluripotent stem cells in vitro. We found that a HIV accessory protein nef is responsible for full-length HIV silencing in human pluripotent stem cells. This effect ...

    • Control of Jaw Movements in Two Species of Macropodines (Macropus eugenii and Macropus rufus) 

      Crompton, Alfred W.; Barnet, J.; Lieberman, Daniel Eric; Owerkowicz, T.; Skinner, J.; Baudinette, R. V. (Elsevier, 2007)
      The masticatory motor patterns of three tammar wallabies and two red kangaroos were determined by analyzing the pattern of electromyographic (EMG) activity of the jaw adductors and correlating it with lower jaw movements, ...

    • Control of lung vascular permeability and endotoxin-induced pulmonary oedema by changes in extracellular matrix mechanics 

      Mammoto, Akiko; Mammoto, Tadanori; Kanapathipillai, Mathumai; Wing Yung, Chong; Jiang, Elisabeth; Jiang, Amanda; Lofgren, Kristopher; Gee, Elaine P. S.; Ingber, Donald E. (Nature Research (part of Springer Nature), 2013)
      Increased vascular permeability contributes to many diseases, including acute respiratory distress syndrome, cancer and inflammation. Most past work on vascular barrier function has focused on soluble regulators, such as ...

    • Control of Neurotransmitter Release Properties by Presynaptic Calcium 

      Thanawala, Monica Shishir (2014-06-06)
      Presynaptic terminals of neurons are optimized for neurotransmitter release, which is tightly controlled by presynaptic calcium. Here, we evaluate the role of calcium influx through voltage-gated calcium channels (VGCCs) ...

    • Control of particulate nitrate air pollution in China 

      Zhai, Shixian; Jacob, Daniel J.; Wang, Xuan; Liu, Zirui; Wen, Tianxue; Shah, Viral; Li, Ke; Moch, Jonathan; Bates, Kelvin H.; Song, Shaojie; Shen, Lu; Zhang, Yuzhong; Luo, Gan; Yu, Fangqun; Sun, Yele; Wang, Litao; Qi, Mengyao; Tao, Jun; Gui, Ke; Xu, Honghui; Zhang, Qiang; Zhao, Tianliang; Wang, Yuesi; Lee, Hyun Chul; Choi, Hyoungwoo; Liao, Hong (Springer Science and Business Media LLC, 2021-04-26)
