Spatio-temporal data is intrinsically high dimensional, so unsupervised modeling is only feasible if we can exploit structure in the process. When the dynamics are local in both space and time, this structure can be exploited by splitting the global field into many lower-dimensional “light cones”. We review light cone decompositions for predictive state reconstruction, introducing three simple ...

The Eastern Sahara (Fig. i) is devoid of surface drainage -this unusual characteristic distinguishes its morphology from that of most other desert regions where running water dominates landscape development (Peel, 1939). Cyclic aridity, which is responsible for the obscuring eolian blankets and wind-erosion effects, had set in by the Pliocene-Pleistocene transition, about 2 million years ago (W...

Using kHz data of the SLR station Graz, spin parameters of the satellite Gravity Probe B (GP-B) are derived; these include spin period and its change over a 1.5 year period, as well as spin direction, and spin axis orientation. The results are compared to the actual data sets as determined by the GP-B mission itself – thus allowing independent confirmation of the kHz SLR derived results.

We present RSLR, an implicit higher order characterization of the class PP of those problems which can be decided in probabilistic polynomial time with error probability smaller than 1/2. Analogously, we can get a characterization of the class BPP. RSLR is an extension of Hofmann’s SLR with a probabilistic primitive. We prove that this system enjoys subject reduction. Polytime soundness is obta...

Spoken Language Recognition (SLR) technology has remarkably improved in the last years, partly thanks to NIST Language Recognition Evaluations (LRE), which have become standard benchmarks for testing new approaches. NIST evaluations focus on narrow-band conversational telephone speech and deal with some specific target languages. Recent efforts to expand the scope of SLR technology assessment i...

S models of reasoning (SLR) proved to be very successful in predicting behavior in the beauty contest game. Recently, a quantified version of the model was suggested as a more general model of thinking. In particular, it was found that the distribution of choices could be represented by a Poisson distribution. I test the model in stylized firstand second-price common-value sealed-bid auctions. ...

Context There is extensive interest in global software development (GSD) which has led to a large number of papers reporting on GSD. A number of systematic literature reviews (SLRs) have attempted to aggregate information from individual studies. Objective: We wish to investigate GSD SLR research with a focus on discovering what research has been conducted in the area and to determine if the SL...

The aim of the study was to evaluate changes in hamstring flexibility in 120 asymptomatic children who participated in a 6-week program consisting of one physiotherapy session per week and daily home exercises. The recruitment criteria included age (10-13 years), no pain, injury or musculoskeletal disorder throughout the previous year, physical activity limited to school sport. Subjects were ra...

Annoying shaky motion is one of the significant problems in home videos, since hand shake is an unavoidable effect when capturing by using a hand-held camcorder. Video stabilization is an important technique to solve this problem. However, the stabilized videos resulted by current methods usually have decreased resolution and are still not so stable. In this paper, we propose a novel, robust, a...

Finding an efficient and computationally feasible approach to deal with the curse of high-dimensionality is a daunting challenge faced by modern biological science. The problem becomes even more severe when the interactions are the research focus. To improve the performance of statistical analyses, we propose a sparse and low-rank (SLR) screening based on the combination of a low-rank interacti...
