We demonstrate a novel experimental arrangement which can rotate a 2D optical lattice at frequencies up to several kilohertz. Ultracold atoms in such a rotating lattice can be used for the direct quantum simulation of strongly correlated systems under large effective magnetic fields, allowing investigation of phenomena such as the fractional quantum Hall effect. Our ...

Protein backbone (15)N spin relaxation rates measured by solution NMR provide useful dynamic information with a site-specific resolution. The conventional method is to record a series of 2D (1)H-(15)N HSQC spectra with varied relaxation delays, and derive relaxation rate from the following curve fitting on the resonance intensities. Proteins with poorly resolved spectra often require ...

Meningiomas are intracranial tumour derived from meningothelial cells, which aggressive behaviour has been frequently associated to cell apoptosis. In this paper activation of several factors involved in apoptosis has been investigated on biopsies of primary, non recurrent meningiomas. Benign (meningotheliomatous, transitional, fibrous, angiomatous), atypical and anaplastic ...

Quality grading of natural materials such as fur, wood and cork has traditionally been done manually. Since the grading by humans is done by assessing the visual quality of the material it has been tempting to try to automate the process using some kind of image analysis. Much research has been devoted to solving this problem. Grading ...

Several critical questions are raised by the proliferation of communications internships, yet the question of grading and evaluating internships is one that can be answered by examining the Media Program at Loyola College in Maryland. Although the communications curriculum was not fully developed until the 1986-87 academic year, enrollments in the program ...

Several studies show that teachers make use of grading practices to affect students' effort and achievement. Generally linearity is assumed in the grading equation, while it is everyone's experience that grading practices are frequently non-linear. Representing grading practices as linear can ...

Research shows that students can articulate a definition of caring and identify specific behaviors of caring teachers. Some of this research also indicates that White students perceive caring differently from African American students. The purpose of this study was to examine what students from different cultural backgrounds and different grade levels identify as the practices ...

Dipole magnets with fields beyond 16T will require superconducting coils that are at least 40 mm thick, an applied pres-stress around 150 MPa and a protection scheme for stored energy in the range of 1-2 MJ/m. The coil size will have a direct impact on the overall magnet cost and the stored energy will raise new questions on protection. To reduce coil size and minimize risk, the coil may have to ...

Decisions about the treatment of neck pain are largely made on the basis of information gained from plain X-rays and magnetic resonance imaging (MRI), which are used routinely as part of preliminary investigation. We performed a descriptive cadaveric study to compare histology with radiography and MRI. We correlated plain radiography, disc height [Farfan index (FI)] and MRI findings with histology ...

We define doubly graded Sn modules Rmu for which we conjecture that the multiplicities of irreducible representations in various bi-degrees are given by the Macdonald coefficients Klambdamu. Assuming one fundamental conjecture, the modules Rmu can be given several equivalent definitions, which we discuss. We prove the conjectures in various special cases. ...
