Spatial modes of light can be used as carriers information in classical optical communication or an alphabet quantum communication. In order to exploit the spatial domain, it is required (de)multiplex different from a shared input channel into output ports. Mode sorters have been employed free-space and fiber systems but date not realized for planar guided waves. Here we present general method ...

Informal recycling workers (IRWs), including waste pickers (WPs) and sorters, are essential constituents of sustainable ecosystems in many cities the Global South. Despite their valuable contributions to economic environmental dimensions urban recycling, most IRWs work precarious conditions. This paper examines recent efforts by local municipalities Izmir implement co-production design as a new...

In the recent years microfluidic technology has affirmed itself as a powerful tool in medical and biological research. Among the different applications, cell manipulation has been widely investigated. Micro-flowcytometers, micromixers, cell sorters and analyzers are only few examples of the developed devices. Various methods for cell manipulation have been proposed, such as hydrodynamic, magnet...

Let and be a partition of f1; : : : ; ng into two blocks. A merging network is a network of comparators which allows as input arbitrary real numbers and has the property that, whenever the input sequence x 1 ; x 2 ; : : : ; x n is such that the subse-quence in the positions and the subsequence in the positions are each sorted, the output sequence will be sorted. We study the class of \recursive...

Many of the phenomena underlying shape recognition can be derived from the greater sensitivity to nonaccidental properties of an image (e.g., whether a contour is straight or curved), which are invariant to orientation in depth, than to the metric properties of an image (e.g., a contour's degree of curvature), which can vary with orientation. What enables this sensitivity? One explanation is th...

BACKGROUND With the advent of high-speed sorters, aerosols are a considerable safety concern when sorting viable infectious materials. We describe a four-part safety procedure for validating the containment. METHODS This procedure includes aerosol containment, physical barriers, environmental controls, and personal protection. The Aerosol Management System (AMS) produces a negative pressure w...

This paper explores applications of digital and analog hardware realizations of median filters suitable for potential use in real-time control and monitoring applications in power electronic circuits and drives. Median filters have the ability to suppress impulse noise in signals, while preserving underlying edges. Filter performance is demonstrated with results from two prototypes.

This paper describes the fabrication of a composite agar/PDMS device for enriching short cells in a population of motile Escherichia coli. The device incorporated ratcheting microchannels, which directed the motion of swimming cells of E. coli through the device, and three sorting junctions, which isolated successively shorter populations of bacteria. The ratcheting microchannels guided cells t...

The ability of quantum walks to evolve in a superposition distinct states has been used as resource communication protocols. Under certain settings, the $k$-cycle discrete-time walks\,(DTQW) are known recur its initial state after every $t_r$ steps. We first present scheme optically realize any DTQW using $J$-plate, orbital angular momentum\,(OAM) sorters, optical switch, and delay line. This e...
