Sparse multipath channels are wireless links commonly found in communication systems such asterrestrial broadcasting, underwater acoustic and cellular land mobile. Their impulse responses arecharacterized by a few significant multipath terms that are widely separated in time. With highspeed transmission, the length of a sampled sparse channel can reach hundreds of symbol intervals,<...

We report a case of multiple sclerosis-associated fulminant tumefactive demyelinating lesion (TDL) with the special feature of delayed humoral immune response. Plasma exchange (PE) yielded significant benefit in two consecutive steroid-unresponsive relapses, while signs of an intrathecal B-cell response were only present 2 years later at the second relapse. Remission was achieved and sustained ...

La identificación de niños bilingües con Trastorno del Desarrollo Lenguaje (TDL) es compleja, y la evaluación narración puede ser particularmente valiosa en este contexto. Por ello, el objetivo estudio contribuir a sistematizar difundir creciente cuerpo literatura que investiga las habilidades narrativas población infantil bilingüe TDL, través una revisión sistemática guiada por siguientes preg...

This paper describes the model-based development process of hard real-time software with the Timing Definition Language (TDL): modeling and simulation of TDL components in Matlab®/Simulink®, their mapping to a specific platform and finally the code generation.

We present a novel technique in which the carbon isotope ratio (delta(13)C) of soil CO(2) is measured from small gas samples (<5 mL) injected into a stream of CO(2)-free air flowing into a tunable diode laser absorption spectrometer (TDL). This new method extends the dynamic range of the TDL to measure CO(2) mole fractions ranging from ambient to pure CO(2), reduces the volume of sample require...

l present a cognitive model of the human ability to acquire causal relationships. I report on experimental evidence demonstrating that human learners acquire accurate causal relationships more rapidly when training examples ore consistent with a general theory of causality. This article describes o learning process thot uses a general theory of causality as background knowledge. The learning pr...

Although human decidual lymphocytes have been widely studied, their function and possible interaction with trophoblast are still unclear. Here we show that whereas human early (EDL) and term (TDL) decidual lymphocytes were unable to kill human trophoblast by necrosis (assessed by the 51Cr-release assay) or apoptosis (DNA fragment assay), TDL but not EDL decreased trophoblast adhesion to a plast...

BACKGROUND Incompleteness of interlobar fissures and pleural adhesions, common in tuberculous destroyed lung (TDL), are among "technical contraindications" for video-assisted thoracoscopic surgery (VATS). The efficacy and safety of VATS in the treatment of TDL, has not yet been detailed in. OBJECTIVE The objective of the present study is to observe the efficacy and safety of VATS in the manag...

Tuberculous destroyed lung (TDL) is diagnosed by a clear past history of tuberculosis with findings of parenchymal destruction verified by chest X-ray. Despite the resultant deterioration of lung function and quality of lives seen in TDL patients, the exact mechanism or characteristics of pulmonary function worsening have not been clearly studied. We investigated the feature of respiratory impa...

The paper sketches how aspects, integrated into a hard real-time programming language, could improve the modularization of embedded software. Based on an overview of the Timing Definition Language (TDL, as described in the TDL language report [1]), we present how aspect-oriented concepts could be woven into that language. A discussion of the advantages and disadvantages of AspectTDL rounds out ...
