Physical Review Special Topics. Accelerators and Beams, 2009 Two-dimensional particle-in cell simulation shows that protons in a small target located in an underdense high-mass plasma can be accelerated by the radiation pressure of a short circularly polarized laser pulse as well as by the wake bubble field of the

Riding the South Sea bubble [PDF]
This paper presents a case study of a well-informed investor in the South Sea bubble. We argue that Hoare's Bank, a fledgling West End London banker, knew that a bubble was in progress and nonetheless invested in the stock; it was profitable to "ride the

Advanced Materials Technologies, EarlyView.Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

On the Low Latitude Scanning Photometer Signatures of Equatorial Ionosphere Plasma Bubbles
Brazilian Journal of Geophysics, 1984 Meridional and east-west scan 6300 Å, night airglow photometers are being extensively used at the low latitude station Cachoeira Paulista (23oS 45oW, dip latitude 14o), Brazil, for investigation of trans equatorial ionospheric plasma bubble ...

Supra-bubble regime for laser acceleration of coldelectron beams in tenuous plasma
, 2009 Relativistic electrons can be accelerated by an ultraintense laser pulse in the "supra-bubble" regime, that is, in the blow-out regime ahead of the plasma bubble (as opposed to the conventional method, when particles remain inside the bubble).

Advanced Optical Materials, EarlyView.Low‐index and low‐loss vdW muscovite represents an emerging robust dielectric platform for the creation of next‐generation all‐vdW nanophotonic architectures. Its utilization as a low‐index building‐block in all‐vdW multilayers enables extreme optical contrast when paired with MoS2, paving the way to the realization of few‐layer ultrathin DBS ...

WHY BUBBLE-BURSTING IS UNPREDICTABLE: WELFARE EFFECTS OF ANTI-BUBBLE POLICY WHEN CENTRAL BANKS MAKE MISTAKES [PDF]
This paper examines the effect of bubble-bursting policy in the case where the central bank sometimes tries to deflate an asset which is not, in fact, overpriced.

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

Deviations from model predictions in measured electron density profiles for low latitudes: A critique [PDF]
Geofísica Internacional, 2004 In situ electron density profiles obtained from equatorial stations in Brazil using conventional Langmuir probes and High Frequency Capacitance probes are compared with IRI predictions in the light of the spectral distribution of the plasma density ...

Stimulated Raman backscattering from a laser wakefield accelerator
New Journal of Physics, 2018 Experiments were performed using the HERCULES laser system at the University of Michigan to study backward stimulated Raman scattering (BSRS) from a laser wakefield accelerator driven with a 30 fs pulse.
