We perform magnetically assisted Sisyphus laser cooling of the triatomic free radical strontium monohydroxide (SrOH). This is achieved with principal optical cycling in the rotationally closed P(N^{''}=1) branch of either the X[over ˜]^{2}Σ^{+}(000)↔A[over ˜]^{2}Π_{1/2}(000) or the X[over ˜]^{2}Σ^{+}(000)↔B[over ˜]^{2}Σ^{+}(000) vibronic transitions. Molecules lost into the excited vibrational ...

One-dimensional nanomaterials have attracted a great deal of research interest in the past few decades due to their unique mechanical, electrical, and optical properties. Changing the shape of nanowires (NWs) is both challenging and crucial to change the property and open wide functions of NWs, such as strain engineering, electronic transport, mechanical properties, band structure, and quantum ...

The microbunching instability driven by collective effects of the beam inside an accelerator can significantly degrade the final electron beam quality for free electron laser (FEL) radiation. In this Letter, we propose an inexpensive scheme to suppress such an instability in accelerators for next generation FEL light sources. Instead of using an expensive device such as a laser heater or RF def...

Filopodial motility is critical for many biological processes, particularly for axon guidance. This motility is based on altering the F-actin-based cytoskeleton, but the mechanisms of how this occurs and the actin-associated proteins that function in this process remain unclear. We investigated two of these proteins found in filopodia, talin and vinculin, by inactivating them in subregions of c...

Abstract Injected electrons and holes are captured into quantum wells with a non-vanishing time. Simulation results presented, showing that this in non-equilibrium of free bound carriers diode laser. Analysis an exemplary laser structure is used to show if the capture time too large, carrier densities regions adjacent well rise strongly beyond their values at threshold very high output power. T...

A complete analysis of the FIR laser Stark/microwave double resonance spectrum of the ~z bending vibration of ArHC1 is given. Hyperfine-resolved spectra of the R(0), R(1), R(2), and P(1) transitions were measured near 25 cm-1 for both chlorine isotopes. Accurate values for the band origins, rotational constants, dipole moments, and quadrupole hyperfine constants were obtained. Comparison with H...

In this paper, we present an improved FBG sensor system using a wavelength swept fiber laser(WSFL) for internal strain monitoring of composite laminates. The WSFL provides unique and functional output characteristics useful for sensor interrogation. In addition a realtime signal processing program was made to measure strains. Five FBG sensors in an optical fiber were used to measure internal st...

An approximate numerical mthod is presented for analysis and determination of modal characteristics in straight, pretwisted non-unifom helicopter blades. The analysis considers the coupled flapwise bending (out of plane), chordwise bending (in plane), and torsion vibration of both rotating and non-rotating blades. The proposed method is based on the integral expansion of Green functions (struct...
