The Cortical Ischemic Core and Not the Consistently Present Penumbra Is a Determinant of Clinical Outcome in Acute Middle Cerebral Artery Occlusion
Background and Purpose— Patient selection for acute stroke therapy based on physiology rather than on time may lead to expansion of the therapeutic window, improved outcomes, an...
Two-wavelength operation of the nonlinear fiber loop mirror
We describe the two-wavelength operation of the nonlinear fiber loop mirror. In this mode of operation a high-power signal at one wavelength switches a low-power signal at anoth...
Congestion avoidance in computer networks with a connectionless network layer: concepts, goals and methodology
The authors compare the concept of congestion with that of flow control and congestion control. A number of possible alternatives for congestion avoidance are identified. From t...
Controlled synthesis and manipulation of ZnO nanorings and nanobows
An experimental procedure is presented for the controlled synthesis and manipulation of ZnO nanorings and nanobows at high purity and large yield. Atomic force microscopy manipu...
WAS IT THERE? DEALING WITH IMPERFECT DETECTION FOR SPECIES PRESENCE/ABSENCE DATA<sup>†</sup>
Summary Species presence/absence surveys are commonly used in monitoring programs, metapopulation studies and habitat modelling, yet they can never be used to confirm that a spe...
An autocompensating fiber-optic quantum cryptography system based on polarization splitting of light
We have developed a system for quantum key distribution (QKD), based on standard telecommunication lasers, detectors, and optical fiber, that passively compensates for time-depe...
Reduced circular field‐of‐view imaging
Abstract A rapid dynamic imaging technique based on polar k ‐space sampling is presented. A gain in temporal resolution is achieved by angular undersampling. A detailed analysis...
Low-frequency active surface plasmon optics on semiconductors
A major challenge in the development of surface plasmon optics or plasmonics is the active control of the propagation of surface plasmon polaritons (SPPs). Here, we demonstrate ...
