Control of Eukaryotic Transcription Elongation
(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
(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
(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)
(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
(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
(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

Control of Shape and Size of Nanopillar Assembly by Adhesion-Mediated Elastocapillary Interaction
(American Chemical Society (ACS), 2010)Control of self-organization of nanofibers into regular clusters upon evaporation-induced assembly is receiving increasing attention due to the potential importance of this process in a range of applications including ... -
Control of soft machines using actuators operated by a Braille display
(Royal Society of Chemistry (RSC), 2014)One strategy for actuating soft machines (e.g., tentacles, grippers, and simple walkers) uses pneumatic inflation of networks of small channels in an elastomeric material. Although the management of a few pneumatic inputs ... -
Control of spin dynamics for applications in Nuclear Magnetic Resonance
(2013-10-17)Sophisticated electromagnetic pulse sequences that control spin dynamics have been developed in Nuclear Magnetic Resonance (NMR) over the last few decades. However, due to more and more demanding criteria, such as unknown ... -
Control of the Mitotic Cleavage Plane by Local Epithelial Topology
(Elsevier (Cell Press), 2011)For nearly 150 years, it has been recognized that cell shape strongly influences the orientation of the mitotic cleavage plane (e.g. Hofmeister, 1863). However, we still understand little about the complex interplay between ... -
Control of Turning Behaviors by Spinal Projection Neurons in the Larval Zebrafish
(2012-09-17)This thesis aims to examine how hindbrain spinal projection neurons (SPNs), namely RoV3, MiV1 and MiV2 control tail undulations during turning behaviors. I find that phototaxic turns differ from forward swims by an increased ... -
Control of Visually Guided Behavior by Distinct Populations of Spinal Projection Neurons
(Nature Publishing Group, 2008)A basic question in the field of motor control is how different actions are represented by activity in spinal projection neurons. We used a new behavioral assay to identify visual stimuli that specifically drive basic motor ... -
Control over Rectification in Supramolecular Tunneling Junctions
(Wiley-Blackwell, 2010) -
Controllable Biomimetic Birdsong
(The Royal Society, 2017-08-02)Birdsong is the product of the controlled generation of sound embodied in a neuromotor system. From a biophysical perspective, a natural question is that of the difficulty of producing birdsong. To address this, we built ... -
Controlled finite momentum pairing and spatially varying order parameter in proximitized HgTe quantum wells
(Springer Nature, 2016)Conventional s-wave superconductivity is understood to arise from singlet pairing of electrons with opposite Fermi momenta, forming Cooper pairs whose net momentum is zero[1]. Several recent studies have focused on structures ... -
Controlled Flight of a Microrobot Powered by Soft Artificial Muscles
(Springer Science and Business Media LLC, 2019-11)Flying insects capable of navigating in highly cluttered natural environments can withstand in-flight collisions because of the combination of their low inertia1 and the resilience of their wings2, exoskeletons1, and ... -
Controlled formation and disappearance of creases
(Royal Society of Chemistry (RSC), 2014)Soft, elastic materials are capable of large and reversible deformation, readily leading to various modes of instability that are often undesirable, but sometimes useful. For example, when a soft elastic material is ... -
Controlled growth and form of precipitating microsculptures
(American Association for the Advancement of Science (AAAS), 2017)Controlled self-assembly of three-dimensional shapes holds great potential for fabrication of functional materials. Their practical realization requires a theoretical framework to quantify and guide the dynamic sculpting ... -
Controlled Growth of Filamentous Fatty Acid Vesicles under Flow
(American Chemical Society, 2014)The earliest forms of cellular life would have required a membrane compartment capable of growth and division. Fatty acid vesicles are an attractive model of protocell membranes, as they can grow into filamentous vesicles ...
