Despite much interest and progress in optical spatial cloaking, a three-dimensional (3D), transmitting, continuously multidirectional cloak in the visible regime has not yet been demonstrated. Here we experimentally demonstrate such a cloak using ray optics, albeit with some edge effects. Our device requires no new materials, uses isotropic off-the-shelf optics, scales easily to cloak arbitrari...

A study of certain representative diuretics on renal function, as measured by the urea clearance test, has been undertaken to determine whether these substances have an accelerating or retarding action on the excretion of urea. Practically, it seemed important to know whether studies of kidney function may be carried out, without interference, during the often necessary administration of diuret...

Financial education is commonly assumed to affect knowledge and behavior, yet its impacts remain relatively untested. Very low-income families in a subsidized housing program were randomly assigned to a mandatory financial education program and tracked for 12 months. Financial education led to improvements in self-reported behaviors, but no measurable effects on savings or credit, except for pa...

Mirror matter admixtures and isospin breaking in the |∆I| = 1/2 rule in Ω − two body non-leptonic decays Abstract We discuss a description of Ω − two body non-leptonic decays based on possible , albeit tiny, admixtures of mirror matter in ordinary hadrons. The |∆I| = 1/2 rule enhancement is obtained as a result of isospin symmetry and, more importantly, the rather large observed deviations from...

Kenyon et al. (STOC 04) compute the distortion between one-dimensional finite point sets when the distortion is small; Papadimitriou and Safra (SODA 05) show that the problem is NP-hard to approximate within a factor of 3, albeit in 3 dimensions. We solve an open problem in these two papers by demonstrating that, when the distortion is large, it is hard to approximate within large factors, even...

The paper investigates the short run responsiveness of National Health Service (NHS) nurses’ labour supply to changes in wages of NHS nurses relative to wages in outside options available to nurses, utilising the panel data aspect of the Annual Survey of Hours and Earnings. We find the short run responsiveness of NHS nurses’ labour supply to the relative wage of NHS nurses is positive and stati...

Using first-principles calculations, we study the electronic structures of Pt/HfO2 interface in the presence of oxygen vacancy. The energetics and charge transfer are examined when the oxygen vacancy is at various distances from the interface. It is found that the oxygen vacancy is strongly attracted to the interface and the charge transfer decreases monotonically as the vacancy moves away from...

Radical cystectomy with pelvic lymphadenectomy is the standard treatment for muscle-invasive bladder cancer. However, the high recurrence rates and high death rate from metastases after radical cystectomy for locally advanced bladder cancer emphasize the high risk of occult distant disease. To improve patient survival, multimodal therapy whereby chemotherapy and surgery are used in concert with...

Cerebral fat embolism (CFE) is a rare, albeit serious complication of long-bone fractures. CFE results in variable neurological disability, often associated with a significant recovery time. Magnetic resonance imaging (MRI), particulary diffusion-weighted imaging (DWI), is the most sensitive method to establish a diagnosis of CFE, with typical findings of multiple punctate highintensity lesions...

This paper reports a controlled prospective unselected real-time comparison of human and computer-aided diagnosis in a series of 304 patients suffering from abdominal pain of acute onset.The computing system's overall diagnostic accuracy (91.8%) was significantly higher than that of the most senior member of the clinical team to see each case (79.6%). It is suggested as a result of these studie...
