Central Asia comprises a large fraction of the world’s drylands, known to be vulnerable to climate change. We analyzed the inter-annual trends and the impact of climate variability in the vegetation greenness for Central Asia from 1982 to 2011 using GIMMS3g normalized difference vegetation index (NDVI) data. In our study, most areas showed an increasing trend during 1982–1991, but experienced a...

These days, companies in the automotive and electronics sector are forced by legal regulations and customer needs to collect a myriad of different indicators regarding sustainability of their products. However, in today’s supply chains, these products are often the result of the collaboration of a large number of companies. Thus, these companies have to apply complex, cross-organizational, and ...

Sediment grain size is measured using a variety of methods, but comparisons of measurement methods on environmental samples are limited. Three instruments (Coulter LS230, Horiba LA900, and SediGraph 5100) utilizing two fundamentally different operating principles were employed to measure a single set of 20 different sediment samples collected at shelf depths from the Southern California Bight. ...

Investigating the internal variability of clouds is of paramount importance to understand, describe, and parameterize the sub-grid processes in large-scale models. In this paper, we focus on the methodology used to study the internal variability of cirrus clouds within the Fokker-Planck equation framework.

We present EPG (electropalatography) and EMA (electro-magnetic articulometry) data from two female speakers of Arrernte, a language of Central Australia. We focus on the apical consonants /t/ and /ʈ/, both of which have previously been shown to have a higher spectral centre of gravity for the stop burst when preceding a stressed syllable. Articulatory results suggest that the tongue is most ret...

This paper reports research investigating the validity of using Pairwise Variability Indexes in research into the second language acquisition of speech rhythm. Findings determined that 1) expert native-speakers rate non-native speaker rhythm based on a common factor, and 2) part of that common factor can be accounted for by the use of vocalic pairwise variability. It was concluded that the PVI ...

Curran-Everett D. Explorations in statistics: correlation. Adv Physiol Educ 34: 186–191, 2010; doi:10.1152/advan.00068.2010.— Learning about statistics is a lot like learning about science: the learning is more meaningful if you can actively explore. This sixth installment of Explorations in Statistics explores correlation, a familiar technique that estimates the magnitude of a straight-line re...

We first present subjects with visual stimuli v: a low contrast Gaussian blob, very quickly flashed at some position in space xv. The subjects are asked to localize the stimulus position x. We find that the subjects estimates are unbiased on average but display some variability from trial to trial. Their estimates P (x|v) can be modelled using a gaussian distribution with mean xv and variabilit...
