Wedemonstratemonolayer(1L)MoS2 grown by chemical vapor deposition (CVD)with transport properties comparable to those of the best exfoliated 1L devices over awide range of carrier densities (up to∼10 cm) and temperatures (80–500 K). Transfer lengthmeasurements decouple the intrinsicmaterialmobility from the contact resistance, at practical carrier densities (>10 cm).We demonstrate the highest c...

We demonstrate the production of organic bottom gate transistors with self-aligned electrodes, using only continuous roll-to-roll (R2R) techniques. The self-alignment allows accurate <5 μm layer-to-layer registration, which is usually a challenge in high-speed R2R environments as the standard registration methods are limited to the millimeter range—or, at best, to tens of μm if online cameras a...

Polymers are receiving considerable attention as components in novel optical systems because of the tailored functionality, ease of manufacturing, and relatively low cost. The processing of layered polymeric systems by coextrusion is a method to produce films comprising hundreds to thousands of alternating layers in a single, one-step roll-to-roll process. Several layered polymer optical system...

The fabrication and advanced function of large area biomimetic superhydrophobic surfaces (SHS) and slippery lubricant-infused porous surfaces (SLIPS) are reported. The use of roll-to-roll nanoimprinting techniques enabled the continuous fabrication of SHS and SLIPS based on hierarchically wrinkled surfaces. Perfluoropolyether hybrid molds were used as flexible molds for roll-to-roll imprinting ...

This paper focuses on the influence of different forms of motion feedback on the perception and control behavior of pilots in a roll-lateral helicopter hover task. To identify this influence, a combined target-following and disturbance-rejection task is carried out where the motion feedback is varied. The participants perform the control task with roll motion only, lateral motion only, combined...

We analyze the weak (2σ) evidence for a running spectral index seen in the three-year WMAP dataset and its implications for single field, slow roll inflation. We assume that the running is comparable to the central value found from the WMAP data analysis, and use the Hubble Slow Roll formalism to follow the evolution of the slow roll parameters. For all parameter choices consistent with a large...

background: preeclampsia is the most prevalent complication of pregnancy and one ihird cause of death in pregnant women. developing of a screening test may help to early diagnosis. this study performed to compare diagnostic value of the roll over test and hematocrit level in early detection of preeclampsia.        methods: 660 pregnant women with gestational age of 24-28 weeks referred totamin ...

We used videography to investigate direct lateral maneuvers, i.e. ‘sideslips’, of the hawkmoth Manduca sexta. M. sexta sideslip by rolling their entire body and wings to reorient their net force vector. During sideslip they increase net aerodynamic force by flapping with greater amplitude, (in both wing elevation and sweep), allowing them to continue to support body weight while rolled. To exec...

Stochastic Structural Stability Theory (SSST) provides an autonomous, deterministic, nonlinear dynamical system for evolving a turbulent mean state. In this work SSST is applied to the problem of understanding the origin and dynamics of roll/streak structures associated with both transition to turbulence and maintenance of the turbulent state. Roll structures in the cross-stream/spanwise plane ...
