In this study, we described the fabrication method for microfluidic channels with circular-cross sectional geometries by reflow phenomenon. The photoresist reflow leads to shape change from rectangular to semicircular, and we optimized the reflow conditions by using positive photoresist to form the perfect cylindrical micropatterns. The resultant circular micropattern was used as a template for...

In practical engineering, the use of Pauli algebra can provide a computational advantage, transforming conventional vector to straightforward matrix manipulations. this work, matrices in cylindrical and spherical coordinates are reported for first time their representing three-dimensional is discussed. This method leads unified representation 3D multivectors with algebra. A significant advantag...

Gamma index pass rates were evaluated for an anthropomorphic phantom using both 2D and 3D calculations. The phantom was irradiated with the traditional dosimetry insert loaded with radiochromic film and TLD, and then with a 3D dosimetry insert. A comparison with the calculated dose distribution showed that both the PRESAGE ® dosimeter and the film and TLD system agreed with the plan to within 5...

Efficient and equitable dispute resolution is key to avoiding systemic disturbance in the use and valorization of top level domain names (TLDs). Such dispute resolution is also important given the increasing number of clashes between TLD providers and managers and between trademark owners and generic (gTLD)-related registrants. ICANN policies/rules form the basis of gTLD-related second level do...

The finite-difference time-domain (FDTD) method is used to simulate three-dimensional (3-D) geometries of realistic ground-penetrating radar (GPR) scenarios. The radar unit is modeled with two transmitters and a receiver in order to cancel the direct signals emitted by the two transmitters at the receiver. The transmitting and receiving antennas are allowed to have arbitrary polarizations. Sing...

OBJECTIVE To examine the effectiveness and feasibility of an evidence-based treatment for weight loss in children. METHODS A total of 41 children who were overweight and their families were provided a modified version of the Traffic Light Diet (TLD) in an applied setting. Children who received treatment as usual (TAU) constituted a comparison sample. RESULTS Children receiving the modified ...

earlier studies have shown conclusively that a tuned liquid damper (tld) is effective for controlling vibrations in structures subjected to narrow-banded wind excitations. a recent numerical study has shown that if the design parameters of a tld are properly set, this device could also be very effective for controlling structural vibration to broad-banded earthquake excitations. here the result...

PURPOSE To determine the in-air azimuthal anisotropy and in-water dose distribution for the 1 cm length of a new elongated (103)Pd brachytherapy source through both experimental measurements and Monte Carlo (MC) simulations. Measured and MC-calculated dose distributions were used to determine the American Association of Physicists in Medicine Task Group No. 43 (TG-43) dosimetry parameters for t...

Extensions of singular spectrum analysis (SSA) for processing of non-rectangular images and time series with gaps are considered. A circular version is suggested, which allows application of the method to the data given on a circle or on a cylinder, e.g. cylindrical projection of a 3D ellipsoid. The constructed Shaped SSA method with planar or circular topology is able to produce low-rank appro...

Transmission of acoustic waves in two-dimensional binary solid/solid composite media composed of arrays of Duralumin cylindrical inclusions embedded in an epoxy resin matrix is studied. The experimental transmission spectrum and theoretical band structure of two periodic arrays of cylinders organized on a square lattice and on a centred rectangular network are reported. Absolute gaps extending ...
