Purpose Although many patients with cerebral large-artery disease (CLAD) show impaired cognitive performance, the risk factors remain unclear in this population. The objective of this study was to evaluate cognitive impairment and its risk factors in patients with CLAD. Methods We recruited non-demented patients with CLAD from our hospital. CLAD was defined as occlusion or stenosis of over 50...

Friction Surfacing Cladding (FSC) is a recently developed, solid-state process to deposit thin metallic clad layers on a substrate. The process employs a hollow rotating tool containing the clad material. The tool is moved along a predefined trajectory at a given distance above the substrate surface while the clad material is pressed out and deposited on the substrate surface beneath the tool. ...

Wave chaos is a concept which has already proved its practical usefulness in design of double-clad fibers for cladding-pumped fiber lasers and fiber amplifiers. In general, classically chaotic geometries will favor strong pump absorption and we address the extent of chaotic wave dynamics in typical air-clad geometries. While air-clad structures supporting sup-wavelength convex air-glass interfa...

We describe CLAD, an implemented advisor system in the domain of clinical medicine. CLAD assists a human physician in making decisions about diagnosing and treating patients. CLAD monitors the transcript of an ongoing dialog between the physician and a patient, builds and augments a mental model of the patient and suggests courses of action to the physician. CLAD can also explain its decisions ...

Progress in the design, fabrication and characterization of electrically injected photonic-crystal quantum-dot microcavity light sources is described. In the devices investigated in this study, the carriers are injected directly into the photonic crystal microcavity, avoiding the surface state recombination in the photonic crystal pattern. A novel and robust air-bridge contact technology is dem...

Clad rebars of four different base materials (20MnSiV, 35# steel, 45# and 55# steel) were successfully produced by a vacuum hot rolling process. A metallographic optical microscope (OM), electron backscatter diffractometer (EBSD), probe micro-analyzer (EPMA), salt spray corrosion chamber used to investigate the clad contour, properties, composite interface microstructure all rebars. The results...

A fiber-based multimodal imaging system that combines multiphoton microscopy (MPM) with Fourier domain optical coherence microscopy (OCM) is reported. The system uses a fiber-based femtosecond laser, a fiber coupler, and a double-clad fiber (DCF) device. The fiber laser has a central wavelength of 1.04 μm and bandwidth of 29 nm. Longer excitation wavelength is used to increase penetration depth...

The Wikipedia is characterized by its dense link structure and a huge amount of articles in different languages, which make it a notable Web corpus for knowledge extraction and mining, in particular for mining the multilingual associations. In this paper, motivated by a psychological theory of word meaning, we propose a graphbased approach to constructing a cross-language association dictionary...

Two fiber Raman probes are presented, one based on an optically-poled double-clad fiber and the second based on an optically-poled double-clad fiber coupler respectively. Optical poling of the core of the fiber allows for the generation of enough 532nm light to perform Raman spectroscopy of a sample of dimethyl sulfoxide (DMSO), when illuminating the waveguide with 1064nm laser light. The Raman...
