Observing, Understanding, and Manipulating Biological Membranes
<p>The phospholipid bilayer is one of the hallmarks of eukaryotic life. This complicated two dimensionally fluid surface is composed of a double layer of lipids which have a region that is hydrophobic and a region that is hydrophilic. The lipid bilayer membranes of a cell act as a barrier that …

Modern VLSI Placement Observing Technology Constraints
… framework that provides solutions while observing modern technology constraints and routability, and optimizing wire length. Addressing the sheer number of circuit components using parallel computing methods makes Eh?Placer one of the fastest placement tools. In addition to Eh?Placer, a …

Modeling and Observing Atmospheres of Terrestrial Exoplanets
… in lava planets. Because of the relative ease in observing these planets, they are currently the best target for detecting a rocky exoplanet atmosphere. We modelled the flow of lava planet K2-141b’s silicate atmosphere and inferred atmospheric pressure, temperature, and wind speed. We found that …

Acquisition of observing responses with delayed conditioned reinforcement
… could be produced by treadle pressing (i.e., an observing response) on a tandem fixed-ratio 1 differential-reinforcement-of-other-behavior 10-s schedule. For the other 3 pigeons, no contingency was implemented for treadle pressing. Treadle pressing was established equally in the presence and …

Results from the QUIET Q-Band Observing Season
… to 2010 December, data from more than 10,000 observing hours were collected, first with the Q-band receiver (2008 October to 2009 June) and then with the W-band receiver (until the end of the 2010 observing season). The QUIET data analysis effort uses two independent pipelines, one consisting …

Observing and measuring the drinking mechanism in cats
This study explores the characteristics of the lapping mechanism in domestic cats (Felis catus). Using high-speed video, digital image processing, and weight measurements we quantify data pertaining to the frequency of lapping and the volume of liquid consumed per lap. These observations allow us …

Observing Renal Responses to Endurance Cycling in the Heat
<p>AIM: To observe the effects of endurance cycling in the heat on renal function, and determine if the extent of impairment is related to hydration. METHODS: 40 cyclists (34 male, 6 female, 52 ± 9 y, 21.7 ± 6.5 % body fat) completed an endurance cycling event (5.7 ± 1.2 hours) in the heat (33.2 ± …

Observing and quantifying transposable element activity inside living cells
Evolution is driven by the activity of transposable elements, ‘jumping genes’ that are ubiquitous to all life forms. To study their dynamics in higher resolution, transposable elements were genetically engineered for tunable expression inside living cells, then tracked in real time using …

Observing the 2D Bose glass in an optical quasicrystal
Quasicrystals are a class of materials that are long-range ordered yet not periodic. These unique features make them a fascinating middle ground between order and disorder, thus providing an ideal platform for studying a wealth of physical phenomena. This thesis contains three experimental works …

Planning and scheduling for earth-observing small satellite constellations
The growth of Earth-observing small satellite constellations requires effective, automated operations management. State-of-the-art techniques must be improved to manage scheduling of observation data collection, data routing through a crosslinked constellation network, and maintenance of limited …

System architecting of a campaign of earth observing satellites
… recommendations on how to plan an Earth observing system of satellites under a variety of design constraints. Through the inclusion of additional climate objectives, other previously planned missions are forced to be removed from the schedule. With these new measurement objectives, this …

Observing microbial processes at the microscale with in situ technology
Marine microbes are key drivers of biogeochemical transformations within the world’s oceans. Although seawater appears uniform at scales that humans often interact with and sample, the world that marine microbes inhabit can be highly heterogeneous, with numerous biological and physical processes …

Observing Wave Propagation of a Float Serve on a Volleyball
There has been research that has determined that the drag forces on a non-spinning volleyball's boundary layer causes the ball to swerve on its trajectory. The purpose of this paper is to develop a numerical model for wave propagation on a volleyball, which we model as a smooth sphere, to show that …

Potentials and limitations of language in observing and interpreting art

Observing microbial processes at the microscale with In Situ technology
Although seawater appears uniform at scales that humans often interact with and sample, the world that marine microbes inhabit can be highly heterogeneous, with numerous biological and physical processes giving rise to resource hotspots where nutrient concentrations exceed background levels by …

Observing residual structure in disordered peptides with multidimensional infrared spectroscopy
An estimated 35% of the human proteome is intrinsically disordered. Disordered proteins play a key role in physiologic and pathologic regulation, recognition, and signaling making protein disorder the subject of increasing investigation. Since disordered samples do not generate x-ray quality …
