A generic analytical performance model of singlechannel wormhole routers is presented using the M/D/1/B queuing theory. Compared with previous work, the flowcontrol feedback mechanism is studied in detail, and a computing method bases on Markov chain for the flowcontrol feedback probability is proposed. Compared with BookSim, a well-known cycle-accurate Network-on-Chip (NoC) simulator, this mod...

In the present analysis, we have modeled the governing equations of a two dimensional hyperbolic tangent fluid model. Using the assumption of long wavelength and low Reynolds number, the governing equations of hyperbolic tangent fluid for an asymmetric channel have been solved using the regular perturbation method. The expression for pressure rise has been calculated using numerical integration...

Surface codes are quantum error correcting typically defined on a 2D array of qubits. A [dx, dz] surface code design is being introduced, where dx(dz) represents the distance for bit (phase) correction, motivated by fact that severity flip and phase errors in physical system asymmetric. We present pseudo-threshold threshold values proposed asymmetric channels presence various degrees asymmetry ...

Quantum repeaters are critical to the development of quantum networks, enabling rates entanglement distribution beyond those attainable by direct transmission. We consider multiple continuous-variable, squeezed light-based flows through a repeater involving noiseless linear amplification and dual homodyne detection. By analyzing single-repeater-enhanced channel model with asymmetric half-channe...

The application of electrical fields within a microfluidic channel enables many forms of manipulation necessary for lab-on-a-chip devices. Patterning electrodes inside the microfluidic channel generally requires multi-step optical lithography. Here, we utilize an ion-implantation process to pattern 3D electrodes within a fluidic channel made of polydimethylsiloxane (PDMS). Electrode structuring...

We report a simple, efficient, one-step, affordable method to produce open-channel paper-based microfluidic channels. One surface of a sheet of paper is selectively calendared, with concomitant hydrophobization, to create the microfluidic channel. Our method involves asymmetric mechanical modification of a paper surface using a rolling ball (ball-point pen) under a controlled amount of applied ...

Congenital myasthenic syndromes (CMS) can arise from presynaptic, synaptic, or postsynaptic defects. Mutations of the acetylcholine receptor (AChR) that increase or decrease the synaptic response to acetylcholine (ACh) are a common cause of the postsynaptic CMS. An increased response occurs in the slow-channel syndromes. Here, dominant mutations in different AChR subunits and in different domai...

The voltage-dependent anion channel 1 (VDAC-1) is an important protein of the outer mitochondrial membrane that transports energy metabolites and is involved in apoptosis. The available structures of VDAC proteins show a wide β-stranded barrel pore, with its N-terminal α-helix (N-α) bound to its interior. Electrophysiology experiments revealed that voltage, its polarity, and membrane compositio...

This work is motivated by the need to understand the ultimate capacity of the outdoor long-distance optical wireless communication with intensity modulation and direct detection. The channel under weak atmospheric turbulence is modeled as a stationary ergodic channel with lognormal intensity fading, where signals experience asymmetric statistics due to on-off keying signaling. Ergodic channel c...
