Cornell is testing superconducting cavities for many different purposes: system development for CESR, supporting technology transfer of CESR SRF systems to storage ring light sources around the world, collaboration with the world-wide TESLA project, collaboration with Muon Collider/Neutrino Factory projects, developing an Energy Recovery Linac (ERL) based synchrotron light source in collaborati...

OBJECTIVES This study aimed to investigate the effect of clinical clerkship-associated achievements, such as performance of procedures at the student clinic, observation, and attitude towards a clerkship, on the objective structured clinical examination (OSCE) scores of dental students graduating in restorative dentistry. MATERIALS AND METHODS The OSCEs consisted of two stations designed to a...

The aim of this study was to evaluate in vitro the effect of sputter-coating for SEM analysis on the formation of cracks on root-end surfaces after retrograde cavity preparation with ultrasonic tips. Root-end cavities were prepared with either Satelec S12/90 degrees D diamond-coated or S12/90 degrees non-coated stainless steel retrotips. Impressions were taken before and after retrograde cavity...

The concept of minimally invasive dentistry certainly promoted significant changes towards more conservative dental caries management, which allows for quality information regarding the diagnosis, prognosis, and clinical management even maintenance restorative procedures. This case report aimed to highlight relevance feasibility a streamlined disease based on caries-risk determination minimal c...

Minimally invasive dentistry is not a very new concept but still many dental practitioners do not know its importance. Many novel dental materials and techniques now work on the principle of minimal invasion. One such technique is air abrasion. Air abrasion was first described by Black (1945).1 His aim was to develop a technique that is effective, works on the principles of minimal invasion and...

This paper introduces the recursive sweeping preconditioner for the numerical solu4 tion of the Helmholtz equation in 3D. This is based on the earlier work of the sweeping preconditioner 5 with the moving perfectly matched layers (PMLs). The key idea is to apply the sweeping precondi6 tioner recursively to the quasi-2D auxiliary problems introduced in the 3D sweeping preconditioner. 7 Compared ...

This paper virtually demonstrates an air cavity formed by a superhydrophobic low-density sphere entering into water with the use of a high-speed camera. Unlike the previous results for a high-density sphere, the low-density sphere pinches off the resulting air cavity at the shorter depth before the cavity has fully grown, and attracts minimal air on the rear surface due to rapid deceleration of...

OBJECTIVE Mechanical bowel preparation is a common practice before laparoscopic gynecologic surgery. This study aims to evaluate its capacity to improve surgical view and bowel handling in the deep pelvis. METHODS A single-blinded, randomized, controlled trial was undertaken with laparoscopic gynecologic surgical patients assigned to one of the following three groups: fasting only; minimal re...

The cooling channel of the CERN reference scenario [1] for a possible neutrino factory [2] requires an approximately 200 m long lattice, which provides solenoidal magnetic fields plus longitudinal electric fields at the same time. The electric real estate field gradient along the structure shall be 2 MV/m at 44 MHz, or 4 MV/m at 88 MHz, respectively. The CERN approach incorporates the solenoids...

We show how to use the radiation pressure optomechanical coupling between a mechanical oscillator and an optical cavity field to generate in a heralded way a single quantum of mechanical motion (a Fock state). Starting with the oscillator close to its ground state, a laser pumping the upper motional sideband produces correlated photon-phonon pairs via optomechanical parametric down-conversion. ...
