Spin- and angle-resolved photoemission studies of the electronic structure of Si(110)”16×2″ surfaces

Posted by klaurent Caltech

Kavli Affiliate: Nathan Lewis | Summary:The electronic structure of Si(110)"16 x 2" double-domain, single-domain and 1 x 1 surfaces have been investigated using spin- and angle-resolved photoemission at sample temperatures of 77 K and 300 K. Angle-resolved photoemission was conducted using horizontally- and vertically-polarised 60 eV and 80 eV photons. Band-dispersion maps revealed four surface […]

Non-isothermal effects on water potential measurement in a simple geometry

Posted by klaurent Cornell

Kavli Affiliate: Abraham Stroock | Summary:In this paper, we investigate quantitatively the coupling between gradients of temperature and of chemical or water potential under steady state conditions in the vapor phase. This coupling is important for the measurement and modeling of the dynamics of water in unsaturated environments like soils and plants. We focus on […]

Discovery of the First Low-Luminosity Quasar at z > 7

Posted by klaurent Tokyo

Kavli Affiliate: Naoshi Sugiyama | Summary:We report the discovery of a quasar at z = 7.07, which was selected from the deep multi-band imaging data collected by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey. This quasar, HSC J124353.93+010038.5, has an order of magnitude lower luminosity than do the other known quasars at z > […]

An Eccentric Massive Jupiter Orbiting a Sub-Giant on a 9.5 Day Period Discovered in the Transiting Exoplanet Survey Satellite Full Frame Images

Posted by klaurent MIT

Kavli Affiliate: Edward Morgan | Summary:We report the discovery of TOI-172 b from the Transiting Exoplanet Survey Satellite (TESS) mission, a massive hot Jupiter transiting a slightly evolved G-star with a 9.48-day orbital period. This is the first planet to be confirmed from analysis of only the TESS full frame images, because the host star […]

The International Linear Collider. A Global Project

Posted by klaurent Tokyo

Kavli Affiliate: Hiroaki Aihara | Summary:A large, world-wide community of physicists is working to realise an exceptional physics program of energy-frontier, electron-positron collisions with the International Linear Collider (ILC). This program will begin with a central focus on high-precision and model-independent measurements of the Higgs boson couplings. This method of searching for new physics beyond […]

Effective Locomotion at Multiple Stride Frequencies Using Proprioceptive Feedback on a Legged Microrobot

Posted by klaurent Harvard

Kavli Affiliate: Robert J. Wood | First 5 Authors: Neel Doshi, Kaushik Jayaram, Samantha Castellanos, Scott Kuindersma, Robert J Wood | Summary: Limitations in actuation, sensing, and computation have forced small legged robots to rely on carefully tuned, mechanically mediated leg trajectories for effective locomotion. Recent advances in manufacturing, however, have enabled the development of […]
