This paper examines the out-of-sample performance of various financial variables as predictors of U.S. recessions. Series such as interest rates and spreads, stock prices, and monetary aggregates are evaluated individually and in comparison with other financial and nonfinancial indicators. The analysis focuses on out-of-sample performance from one to eight quarters ahead. Results show that stoc...

In this paper, we investigate competition in banking systems in the EU27 as a whole for the period 2004– 2010, but also for old members’ banking systems compared with new members’ banking systems and for banking systems from countries member of euro zone compares with banking systems from countries non-member of euro zone. In order to investigate this issue, we estimate a non-structural indicat...

Understanding the neural basis of behaviour requires studying brain activity in behaving subjects using complementary techniques that measure neural responses at multiple spatial scales, and developing computational tools for understanding the mapping between these measurements. Here we report the first results of widefield imaging of genetically encoded calcium indicator (GCaMP6f) signals from...

It is widely recognized that citation counts for papers from different fields cannot be directly compared because different scientific fields adopt different citation practices. Citation counts are also strongly biased by paper age since older papers had more time to attract citations. Various procedures aim at suppressing these biases and give rise to new normalized indicators, such as the rel...

We present a modular approach for analyzing calcium imaging recordings of large neuronal ensembles. Our goal is to simultaneously identify the locations of the neurons, demix spatially overlapping components, and denoise and deconvolve the spiking activity from the slow dynamics of the calcium indicator. Our approach relies on a constrained nonnegative matrix factorization that expresses the sp...

LH: Can you give me an example of a student project in the senior course? GA: One example is a study of how much phytoplankton biomass is produced under a particular set of circumstances, i.e., depth, temperature, or pressure. The students spend time in lab over spring break learning the techniques for chlorophyll extraction as a biomass indicator, and learning DOI: 10.1187/cbe.10–06–0074 Addre...

Do structural patterns tell us something about the text content? In order to give a preliminary answer to this question, an experiment in automatic text classification is performed using only surface-structural features. The features extracted – as, e.g., the complexity, length or depth of text constituents (Köhler, 1999), – produced surprisingly good classification results. This finding argues...

Neurons in the extrastriate visual area V5/MT show perceptually relevant signals in binocular depth tasks, which can be measured as a choice probability (CP) for the neuron. The presence of a CP in a particular paradigm may be an indicator that the neuron is generally part of the substrate for the perception of binocular depth. We compared the responses of those single neurons that show CPs in ...

Aggregative data infrastructures (ADIs) are information systems where organizations can find the tools to integrate their data sources to form uniform and richer information spaces of object metadata descriptions. Novel sustainable approaches for the realization of ADIs are based on the adoption of ADI enabling technologies which support the realization, maintenance and upgrade of ADIs and prom...

Abstract. Vegetation optical depth (VOD) retrieved from microwave radiometry correlates with the total amount of water in vegetation, based on theoretical and empirical evidence. Because vegetation varies relative content (as well as biomass), this correlation further suggests a possible relationship between VOD plant potential, quantity that drives hydraulic behavior. Previous studies have fou...
