One popular Natural Flood Management (NFM) technique involves the construction of channel-spanning woody dams in low-order streams that maintain a clearance height above base flows. While extensive research has examined geomorphic effects natural wood accumulations, little been documented NFM dams, which are structurally distinct from accumulations and may produce different patterns erosion dep...

Restoration of eroded blanket peatlands through revegetation and gully blocking is observed to also deliver significant natural flood management (NFM) benefits (reduce delay floodpeaks). But there a lack clear understanding regarding how different catchment processes interact/counteract under each intervention scenario. We seek provide more insight by rigorously calibrating TOPMODEL rainfall-ru...

In this work we present the highest spatial and spectral resolution integral field observations to date of bipolar jet from Orion proplyd 244-440 using MUSE NFM) on VLT. We observed a previously unreported chain six distinct knots in roughly S-shaped pattern, by comparing them with HST images estimated proper motions redshifted 9.5 mas yr$^{-1}$ an inclination angle $73^{\circ}$, though these q...

The quantum phase description of Noh, Fougères and Mandel (NFM) leads to a two-mode theory of phase in the strong local oscillator limit. We show that the explicit form of the eigenstates of the sine and the cosine phase operators in two-mode Fock space can be constructed. This brings great convenience to the NFM quantum phase approach. Recently, phase operators and phase measurements in quantu...

Jets and outflows are thought to play important roles in regulating star formation disk evolution. HD 163296 is a well-studied Herbig Ae that hosts proto-planet candidates, protoplanetary disk, protostellar jet, molecular outflow, which makes it an excellent laboratory for studying jets. We aim characterize the jet at inner regions check if there large differences with features separations. A s...

This paper demonstrates that scanning probe microscopies (SPMs) can image patterned self-assembled monolayers (SAMs) formed by microcontact printing. Lateral force microscopy (LFM) and force modulation microscopy (FMM) showed contrast between regions of patterned SAMs terminated by different chemical functionalities. Normal force microscopy (NFM) typically showed less contrast than LFM or FMM b...

Neural Field models (NFM) play an important role in the understanding of neural population dynamics on a mesoscopic spatial and temporal scale. Their numerical simulation is an essential element in the analysis of their spatio-temporal dynamics. The simulation tool described in this work considers scalar spatially homogeneous neural fields taking into account a finite axonal transmission speed ...

A membrane-based gas absorption (MGA) process was evaluated for the removal of volatile organic compounds (VOCs) based on C6H6/N2 mixture. The absorption of C6H6 from a C6H6/N2 mixture was investigated using a hydrophobic polypropylene hollow fiber membrane contactor and the aqueous solution of N-formyl morpholine (NFM) as absorbent. The effects of various factors on the overall mass transfer c...

This work deals with various investigations into the accuracy of a newly developed planar nanopositioning machine. machine, called Nanofabrication Machine 100 (NFM-100), has positioning range mm in diameter. To determine precision, movement scenarios are performed machine table, and trajectory deviation from set is determined. In particular, focus on high velocities up to 20 mm/s. Even at speed...
