It is shown that certain natural quantum logic gates, i.e. unitary time evolution matrices for spin2 quantum spins, can be represented as sums, with appropriate phases, over classical logic gates, in a direct analogy with the Feynman path integral representation of quantum mechanics. On the other hand, it is shown that a natural quantum gate obtained by analytically continuing the transfer matr...

To improve the existing designs of hydraulic automatic gates with flexible working bodies for partition structures on channels, object study was development and an innovative design autoregulator water level bodies. The study's main objective to create a structure that provides control, discharge excess water, washing deposits in front partition, determining its throughput. developed consists g...

Freezing of Gait (FOG) is a common condition in people with Parkinson's disease (PD). FOG entails suddenly experiencing difficulties moving or feeling that one's feet are as glued to the ground. It is triggered, e.g., when passing through doorways. Earlier studies suggest that being in natural environments affects FOG in a positive way. Five subjects were recruited to serve as five single subje...

In the present paper, first in a series of two, we propose model universal quantum computation using fermionic or bosonic multiparticle continuous-time walk with two internal states (e.g., spin-up and -down an electron). A dual-rail encoding is adopted to convert information: single qubit represented by presence walker either parallel paths. We develop roundabout gate that moves from one path n...

For multiport image-guided minimally invasive surgery at the lateral skull base a quality management is necessary to avoid the damage of closely spaced critical neurovascular structures. So far there is no standardized method applicable independently from the surgery. Therefore, we adapt a quality management method, the quality gates (QG), which is well established in, for example, the automoti...

Rockfill dams are accounted as useful measures in watershed management projects. How-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. Previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures However; there is no general relationship to estimate the sediment transport rat...

We propose a new general-purpose computer architecture based on programmable logic. It consists of a dual-structured array of cells accommodating a fixed “built-in part” and a freely programmable “plastic part”. We call this composition the “Plastic Cell Architecture” (PCA). The built-in part with its fully connective two-dimensional mesh structure serves as a communication platform based on th...
