Ascending and descending techniques are used to demonstrate the male anterior urethra. The authors developed an ultrasound approach with the patient compressing his own urethra manually during voiding to achieve distension of the urethra with urine. The subsequent sonourethrography is more accurate than conventional fluoroscopic contrast studies in defining urethral filling defects and is as ac...

We present an experimental demonstration of quantum optical coherence tomography (QOCT). The technique makes use of an entangled twin-photon light source to carry out axial optical sectioning. QOCT is compared to conventional optical coherence tomography (OCT). The immunity of QOCT to dispersion, as well as a factor of two enhancement in resolution, are experimentally demonstrated. PACS numbers...

SUMMARY Conventional imaging protocols are unable to visualize the intraforaminal/canalicular segments of the lower cranial nerves (IX-XII). On the basis of previous successful demonstration of individual cranial nerves within the cavernous sinus by constructive interference in steady-state MR imaging, we describe the use of contrast-enhanced 3D fast imaging employing steady-state acquisition M...

A Chinese team of physicists have trained a quantum computer to recognise handwritten characters, the first demonstration of “quantum artificial intelligence”. Physicists have long claimed that quantum computers have the potential to dramatically outperform the most powerful conventional processors. The secret sauce at work here is the strange quantum phenomenon of superposition, where a quantu...

The Incremental Interaction Manager supports the use of incremental speech recognition with conventional turn-based dialogue managers. We demonstrate its use in a complete statistical dialogue system in the “Lets Go” bus information domain. Our demonstration is two-fold. First, the user is able to call the system and have a complete dialogue. They are then able to inspect their own call using a...

We present the first experimental demonstration (to our knowledge) of long-distance unperturbed fundamental optical soliton transmission in conventional single-mode optical fiber. The virtual transparency in the fiber required for soliton transmission, over 15 complete periods, was achieved by using an ultralong Raman fiber laser amplification scheme. Optical soliton pulse duration, pulse bandw...

The HyperNet (Hypercube based neural Network) architecture uses higher-order sigmapi units which are realisable with conventional memory technology. Real-valued node input and output vectors promote automatic generalisation and allow the architecture to interface to analogue data. Hardware implementation of real-valued inputs as parallel stochastic bit streams provides a cost effective realisat...

We present a novel approach which unifies conventional learning from demonstration (LfD) and motion planning using probabilistic inference, for generalizable skill reproduction. As a part of this approach, we also present a new probabilistic skill model that requires minimal parameter tuning, and is more suited for encoding skill constraints and performing inference in an efficient manner. Prel...

Cryogenic, high-resolution X-ray detectors have potential applications in industrial .X-ray fluorescence (XRF) analysis. We discuss various XRF analysis techniques currently used in the semiconductor industry, problems encountered clue to limitations of current detectors and the potential benefits of using cryogen ic detectors in these applications. We give examples of demonstration experiments...

The Ka-band interferometric radiometer is developed as a demonstration model of 2-D interferometric radiometer to evaluate sub-Y-type array which was proposed by the research group SSL at K-JIST. This new antenna configuration is proposed for high spatial resolution imaging radiometer and it shows better performance than conventional Y-type array. The implemented radiometer is developed at 37 G...
