    • Preparing for the America's Cup: A technological and a human challenge

      Fischer, Martin (2017-01-17)
      The America's Cup is the pinnacle event in sailing and it is the oldest sports trophy in the world. The trophy was originally awarded in 1851 for a race around the Isle of Wight, which was won by the schooner ムAmericaメ. It was subsequently renamed after the yacht and was donated to the New York Yacht Club under the terms of the Deed of Gift, which made the Cup available for perpetual international competition. The 35th America's Cup will be held in May / June 2017 in Bermuda. The races will be sailed in 50-ft foiling catamarans. Instead of a main sail the boats feature a rigid wing. These boats are capable of sailing 3 times the wind speed, with top speeds reaching 45 knots. The lecture describes the technological and human endeavor to develop and prepare the boat and the crew. Developing an America's Cup boat is a multidisciplinary effort. Excellence is required in such different fields as aerodynamics, hydrodynamics, structural analysis, advanced composite engineering and building, design of mechanical control systems, hydraulics, electronics and flight control, to name the most important ones. Since automatic control systems (autopilots) are forbidden in the America's Cup rules there is a strong two-way feedback between sailing practicalities and the technological choices being made. Combine this with the management of a very tight build schedule for hulls, beams, foils, rudders and the wing and you get an idea what it means to prepare for the America's Cup.
    • From Exploration to Exploitation? Opportunities and Imperatives in the Deep Sea

      Van Dover, Cindy Lee (2017-01-16)
      We may think of the depths of the ocean as unseen, unfathomable, but there have been breakthroughs in technology that allow scientists access to the deep sea and that bring the deep sea directly to the public through live video feeds and data links. We can now map the seafloor to resolve features the size of a football and smaller using sound waves, while at the same time, sensors report to us the chemical nature of the surrounding environment. We will look at examples of robots and other assets that we use to explore the seafloor and at some of the discoveries that arise from our expanding capabilities. We will look at some of the blank places on the map and wonder what might be located there. And finally, we will explore the growing interest in mining the seabed and the potential for a Blue Economy in the deep ocean.
    • Choosing to Fly: Examining Fear, Risk and Resilience

      Davis, Steph (2017-01-15)
      Steph Davis was raised as a classical piano student in a traditional, academic family. She ultimately quit music and then law school, making the frightening decision to step off the safe road and follow her passion to become a full-time rock climber. In 25 years of climbing, Steph has applied the principles of discipline and practice she learned as a musician to reach the tops of some of the world's most difficult rock walls and mountains, often climbing solo without a rope or safety equipment. Intrigued by the power of fear and how it affects our ability to succeed and to stay safe, she learned to skydive as a literal way to face her own fears of falling. From skydiving, Steph immersed herself in the pursuit of wingsuit BASE jumping, known as the most advanced and dangerous form of human flight, in order to fly off mountains after climbing up them. Living and surviving in the mountains and the air, Steph has developed a deep understanding of the need to adapt to one's environment, to embrace failure and to come to terms with fear--skills which are also crucial for survival and success in any walk of life. After the loss of her husband on a wingsuit flight in the Dolomites, Steph saw that resilience is a choice. The decision to keep going forward and to embrace life fully in the face of loss is a simple and yet profound decision that we can all make, no matter what challenges we face. Simply by deciding that we want to go somewhere, whether physically or mentally, we've taken the first step to getting there.
    • Pushing the Limits of Kinetic Arts: Strandbeests

      Jansen, Theo (2017-01-12)
      In 1990, Dutch artist Theo Jansen introduced the world to his newest creation, the strandbeests. Kenetic sculptures created from plastic tubing, water bottles, and pipes, these beests survive on their own. These herds live on beaches all around the world, surviving on their waterfeelers and sandfeelers to remain safely on the sand. Powered by wind, these new life forms do not require food! Join us for a keynote lecture with Theo as he discusses the story behind the strandbeests as he pushes the limits with these beautiful and unique animals.
    • Hyperloop: The Future of Transportation

      Ahlborn, Dirk (2017-01-11)
      What is Hyperloop? Hyperloop is a new way to move people or things anywhere in the world quickly, safely, efficiently, on-demand and with minimal impact to the environment. The system, using updated technologies, by Elon Musk, relies on electric propulsion to accelerate a passenger or cargo vehicle through a tube in a low-pressure environment. The autonomous vehicle levitates slightly above the track and glides at faster-than-airline speeds over long distances. We eliminate direct emissions, noise, delay, weather concerns and pilot error. Itメs the next mode of transportation.
    • Innovation at UNICEF: How to Help Balance an Asymmetric World

      Fabian, Christopher (2017-01-10)
      Using science, technology, and venture investment to help balance an asymmetric world How do we find solutions to the greatest challenges facing humanity? UNICEF's Office of Innovation (www.unicefstories.org) helps the world's leading children's organization use new methods and approaches to identify, invest in, and scale open source technologies that benefit children, and the world. This talk will share our approach to developing solutions to billion-person problems - a hybrid between the world of Silicon Valley venture capital and the world of global development, policy, and governmental change. Chris will discuss using data, science, and failure to drive investment and development decisions, as well as issues in developing good companies that also want to do good. Examples from Uganda, Estonia, China, Nigeria, and more show that new portfolios of (sometimes surprisingly simple) technologies can create global collaborations around issues important to us all.
    • The Voyager Journey to Interstellar Space

      Stone, Edward (2017-01-09)
      Edward Stone joined Caltech as a research fellow in physics after receiving his Master of Science degree and Ph.D. in physics at the University of Chicago. Over the years, he held a variety of positions, from assistant professor to Vice-President for Astronomical Facilities. In 1972 he became project scientist for the Voyager mission, a position he currently still holds. He was nationally known as the Jet Propulsion Laboratory (JPL) public spokesman during the planetary flybys, explaining the Voyager's scientific discoveries to the public. He became the Director of Jet Propulsion Laboratory (JPL) from January 1991 to April 2001. While Stone was Director, JPL's Mars Pathfinder and its Sojourner rover sent back images that were seen by millions of people on television and the Web. Highlights of his decade of leadership as the Direction of JPL include Galileo's five-year orbital mission to Jupiter, the launch of Cassini to Saturn, the launch of Mars Global Surveyor and a new generation of Earth science satellites such as TOPEX/Poseidon and SeaWinds.

    • Short consensus repeat domains extend the E-selectin structure in order to grab cells out of flow

      Aleisa, Fajr A; Sakashita, Kosuke; Lee, Jaeman; Abu Samra, Dina Bashir Kamil; Habuchi, Satoshi; Kusakabe, Takahiro; Merzaban, Jasmeen (2017-01-08)
      Selectins are key adhesion molecules responsible for initiating a multistep process that leads a cell out of the blood circulation and into a tissue or organ. They are composed of an N-terminal extracellular C-type lectin like domain, followed by an Endothelial Growth Factor like domain (EGF), a defined number of short consensus repeats SCR (also called “sushi” domains), a transmembrane domain and a C-terminal cytoplasmic tail. The adhesion of cells (expressing ligands) to the endothelium (expressing the selection i.e., E-selectin) occurs through the interaction between the lectin domain of selectins and sLeX presenting ligands. Structural/function studies to date have mainly focused on investigating the influence of the lectin domain of E-selectin on its ability to bind its ligands while other domains received less atention. We prepared a number of different recombinant E-selectin proteins with changes in the SCR units. Specifically we generated wild-type E-selectin proteins as monomeric or dimeric structures, mutant proteins with varied numbers of SCRs as well as proteins where strategic residues were mutated to change the conformation of the selectin. Using a novel real time immunoprecipitation surface plasmon resonance (SPR)-based in vitro binding study developed in our lab, the interaction of recombinant E-selectin proteins with immunoprecipitated endogenous ligands (i.e. CD44) captured on a CM-5 chip was assessed. These studies provided quantitative binding kinetics with on and off rates of selectin-ligand interactions and suggested that robust binding is dependent on the presence of the SCRs and oligomerization. These results provide significant implications on the functional mechanism of E-selectin binding to its ligands.

    • Role of interlayer coupling for the power factor of CuSbS2 and CuSbSe2

      Alsaleh, Najebah Mohammed Abdullah; Singh, Nirpendra; Schwingenschlögl, Udo (2017-01-08)
      The electronic and transport properties of bulk and monolayer CuSbS2 and CuSbSe2 are determined by using density functional theory and semiclassical Boltzmann transport theory, in order to investigate the role of interlayer coupling for the thermoelectric properties. The calculated band gaps of the bulk compounds are in agreement with experiments and significantly higher than those of the monolayers, which thus show lower Seebeck coefficients. Since also the electrical conductivity is lower, the monolayers are characterized by lower power factors. Therefore, interlayer coupling is found to be essential for the excellent thermoelectric response of CuSbS2 and CuSbSe2, even though it is weak.
