A diffractive optical element (DOE) is a promising means of converting a single spot to multiple spots. The multi-level structures of the DOE exhibit a high performance. The DOE structure has the same shape as the multi-level free-form design. This DOE, made of SiO 2 , withstands a high power and peak laser and has a…
BACKGROUND: Malignant gliomas are known to contain proportions of both neovascularized and infiltrative, non-enhancing tumor (NET). Additionally, a substantial proportion of treated tumors can have NET progression prior to contrast enhancement. There remains significant need for objective evaluation of NET; however, t…

BACKGROUND: American Academy of Neurology's 2000 practice parameter do not support routine use of prophylactic antiepileptic drugs (AEDs) in newly diagnosed brain tumors. If used in the perioperative setting, they should be discontinued after the first postoperative week. However, it remains unclear whether such recom…
We presented a low-cost and high performance layer-by-layer (LBL) self-assembled carbon nanotube (CNT) biosensor with TiO2nanoparticles coated micro-channel integrated. The microfluidic channel surface is super hydrophilic after TiO2nanoparticle deposition and is capable of automating liquid sampling. It is able to gi…
Our project work is performed on take-down tension and production/min of a Mayer and Cie machine. The main output of this paper is that with increase in production, the take-down tension is also increased. In this project work we have established a relationship between take-down tension and production/min. When we div…
BACKGROUND: Blood-based, circulating biomarkers play an important role in the detection and care for many cancer types. Such a biomarker is not clinically available for gliomas, even though there is pressing need for improved assessment of disease response and progression. The objective of this study was to explore ei…
In-situ synchrotron small-angle X-ray scattering measurements and quantitative data analysis were used to investigate isothermal self-assembly in a series of high-performance poly(1,4-cyclohexyldimethylene-co-ethylene terephthalate)s (PCETs) enriched with 1,4-cyclohexanedimethanol (CHDM). Interestingly, the bulky CHDM…
Malignant brain tumor is highly aggressive disease with high recurrence and motility rate. Current therapeutic approaches including surgery, radiation and chemotherapy only provide limited disease progression control. One of the major issues results its poor outcome is the blockade of chemotherapeutic agent delivery b…
We performed micromagnetic modeling on moving multiple data bits (2-64 bits) in permalloy (Ni80Fe20) cylindrical nanotubes (PCNTs) and numerically investigated the domain-wall movement, which relies on the applied current, the Gilbert damping factor α, and radii ratio β. It was found that current-driven multiple trans…

BACKGROUND: Modern radiation techniques are being used to attempt hippocampal-sparing whole brain RT in brain metastasis in order to minimize neurocognitive decline. However this technique is accompanied by potential risk of hippocampal recurrence. AIMS: To evaluate the incidence of metastasis in the hippocampal regio…
Fabrication of different porous silicon structures, namely rugate filters and rugate filters with porous silicon monolayers on top, as well as the characterization of both their reflectivity spectrum and their sensing performance are presented. The focus of this work is on a thorough analysis of the different optical…
3-D simulations of electromagnetic field by finite difference time-domain (FDTD) algorithm were helpful for analyzing propagations of electromagnetic wave. In industrial fields, FDTD simulations are necessary to design telecommunication devices. Furthermore, structures of photonic crystal and light transmissions in na…
The effects of size on the magnetic properties of HoMn2O5nanorods were studied. Nanorods were made with five radial (C>) × axial lengths - 24(7) nm × 49(19) nm, 33(14) nm × 66(25) nm, 31(9) nm × 69(25) nm, 54(13) nm × 95(27) nm, and 114(52) nm × 409(109) nm. The axial directions of the nanorod were parallel to the c-a…
To evaluate the role of gamma knife (GK) as a treatment modality for primary central nervous system lymphomas (PCNSL), we reviewed PCNSL patients who were treated with GK between November 2004 and May 2014, retrospectively. There were 29 cases (13 males and 16 females, ranged from 33 years old to 91 years old) with 21…
Electromagnetic noise suppression was studied by near-field power absorption of a magnetic composite film composed of magnetic fillers and metallic mesh grid in nonmagnetic matrix, which were simulated using a commercial finite-element electromagnetic solver. The geometrical characteristics of the grid on the power ab…
Ni0.5Cux/2Zn(0.5-x/2)Fe2O4(where x\(= 0.3\) , 0.4, 0.5, and 0.6) ferrites were prepared at different chemical reaction temperatures (100 °C, 125 °C, and 150 °C) and then were further sintered using domestic microwave oven. X-ray diffraction revealed the ferrite phase formation and proved that chemical reaction tempera…
The detection limit of thin film giant magneto-impedance (GMI) magnetic sensors has been investigated by measuring their magnetic noise. Samples were patterned by photolithography from sputtered multilayers, in the form of stripes with lengths of 0.5 to 2 mm and widths of 50 to 130 μm. The layer structure [Ni80Fe20(17…
Introduction: Cardiac glycosides such as digoxin or digitoxin are the natural products that are traditionally used to increase cardiac contractile force in patients with heart failure and cardiac arrhythmias. It has been shown that digoxin can directly inhibit the cell proliferation and lead to cell apoptosis. Present…
