The primary treatment of thyroid carcinoma is surgery and the outcome depends on its extent. The post-operative management alternatives in thyroid carcinoma include thyroid hormone, radio-iodine ablation (I-131 Na), external beam radiation therapy (EBRT) and occasionally adjuvant chemotherapy. This retrospective study analyzes the managements of 153 patients (102, 51), age range 10-96 yea...

Highlights Focused Ion Beam Lithography is a very powerful technique for directly writing patterns on many substrates, it is a mask-less and resist-less technique that allows a very wide range of applications, providing a resolution down to 10 nm. Joined to the Electron Beam Lithography and the Gas Deposition System it became a very versatile tool for many fabrication processes. Using a dual-be...

Immersion and interactive experience are introduced into a Solid Mechanics beam bending lab exercise by utilizing gesture-based analysis that is inexpensive, utilizes off-the-shelf cameras, and is highly portable for ease of use in the classroom. A cantilever I-beam is rendered in virtual reality (VR) and a user’s gestures are captured and interpreted in real-time to allow for natural interacti...

A new luminescence beam profile monitor is realized in the polarized hydrogen gas jet target at the Relativistic Heavy Ion Collider (RHIC) facility. In addition to the spin polarization of the proton beam being routinely measured by the hydrogen gas jet, the luminescence produced by beam-hydrogen excitation leads to a strong Balmer series lines emission. A selected hydrogen Balmer line is spect...

In this document I consider the performance of a long pulse spallation source for those neutron scattering experiments that are usually performed with a monochromatic beam at a continuous wave (CW) source such as a nuclear reactor [ 11. This class of expeijments can be represented generically by the upper part of Figure 1. A monochromatic neutron beam with wavevector ki falls on a sample and th...

1,+2.6XlO-“~X,2 I Ln,B,, dl. 0) rl in-phase components of the polarization angle modulation $. The method is insensitive to laser power variations and path length changes in the probe beam optical circuit and is robust to plasma refractive beam bending. Using a local oscillator derived from the Faraday rotated beam itself, the signals obtained at the two output ports can also be made proportion...

In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. The plasma was induced by a 1064 nm Nd:YAG laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (I) a solution (highly diluted salt water as a conductor) and (II) a colloidal (TiO2 in colloidal nanoparticle form as a dielectric...

In this paper, we have investigated the effects of self-fields on gain in a helical wiggler free electron laser with axial magnetic field and ion-channel guiding. The self-electric and self-magnetic fields of a relativistic electron beam passing through a helical wiggler are analyzed. The electron trajectories and the small signal gain are derived. Numerical investigation is shown that for grou...

A new rigid-rotor Vlasov equilibrium is obtained for an intense, axisymmetric chargedparticle beam with uniform density in the radial direction propagating through a periodic solenoidal focusing field. The beam envelope equation is derived, and examples of periodically focused rigid-rotor Vlasov equilibria are presented. Statistical properties and possible applications of the present beam equil...

SimTrack is a compact c++ library of 6-d symplectic element-by-element particle tracking in accelerators originally designed for head-on beam-beam compensation simulation studies in the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. It provides a 6-d symplectic orbit tracking with the 4th order symplectic integration for magnet elements and the 6-d symplectic synchro-...
