To evaluate a possible role for colony stimulating factor-1 (CSF-1) in human ovarian function, the peripheral blood CSF-1 concentration throughout the human menstrual cycle and during ovarian stimulation was monitored. Blood was sampled across the menstrual cycle (n = 10) and at specific times during ovarian stimulation. In addition, the CSF-1 concentrations in follicular fluid (FF) during the ...

With the resurgence of active noise control in the past two decades, the design and implementation of optimal noise cancellers has been a topic of considerable research. Recently, much of the investigation is focused on fixed controllers that rely on the robustness of closed loop systems to deal with poorly parameterized or changing plants. Many acoustic systems employ internal model controller...

We analyze the facial structure of the polytope associated to the GMSTP with the aim of nding \good" inequalities to strengthen our previous linear formulations. Several families of inequalities which are facet-inducing for the polytope of the GMSTP are investigated. Our proofs of \facetness" for valid inequalities of the GMSTP polytope use tools developped in [3] and also classical results fro...

Glottal flows and sound pressure waveforms of four different fundamental frequencies were generated using a computational model of vocal fold vibration and acoustic wave propagation in order to evaluate the performance of an inverse filtering method. Four time-based parameters of the glottal flow were used in order to assess the accuracy of the inverse filtering technique. The results show that...

This paper presents our system participated on SemEval-2012 task: Chinese Semantic Dependency Parsing. Our system extends the second-order MST model by adding two third-order features. The two third-order features are grand-sibling and tri-sibling. In the decoding phase, we keep the k best results for each span. After using the selected third-order features, our system presently achieves LAS of...

The optimal perceptual decision making strategy for weighting serially presented information depends on the degree of sample dependence. Uniform weighting produces optimal estimates from independent samples, but increases in autocorrelation should be matched by increasing and symmetric overweighting of early and late samples in order to maintain optimal performance. In the current experiment, p...

The performance of decision feedback equalizers (DFE’s) working on a noiseless channel with correct tap weights is studied. We show that the space of channel parameters can accordingly be partitioned into a finite number of sets. The error recovery performance of a DFE is the same for all DFE’s within one such set, and is determinable. We also discuss some tight bounds for recovery time statist...
