Searching microblog posts, with their limited length and creative language usage, is challenging. We frame the microblog search problem as a data fusion problem. We examine the effectiveness of a recent cluster-based fusion method on the task of retrieving microblog posts. We find that in the optimal setting the contribution of the clustering information is very limited, which we hypothesize to...

As soon as practical, Earth’s low-cost, abundant, environmentally attractive fusion energy resources should be applied to the urgent global challenges of climate change, energy supply, economic growth, and the developing world. A National Ignition Campaign is under way at the recently completed National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) to ignite high-gain...

Aerobic sn-glycerol 3-phosphate dehydrogenase, encoded by the glpD gene of Escherichia coli, is a cytoplasmic membrane-associated respiratory enzyme. The nucleotide sequence of glpD was determined. An open reading frame of 501 codons was preceded by a consensus Shine-Dalgarno sequence. The proposed translational start and reading frame of glpD were confirmed by determining the nucleotide sequen...

The availability of high-speed 3D video sensors has greatly facilitated 3D shape acquisition of dynamic and deformable objects, but high frame rate 3D reconstruction is always degraded by spatial noise and temporal fluctuations. This paper presents a simple yet powerful intensity video guided multiframe 4D fusion pipeline. Temporal tracking of intensity image points (of moving and deforming obj...

A sensor fusion method was developed for vertical channel stabilization by fusing inertial measurements from an Inertial Measurement Unit (IMU) and pressure altitude measurements from a barometric altimeter integrated in the same device (baro-IMU). An Extended Kalman Filter (EKF) estimated the quaternion from the sensor frame to the navigation frame; the sensed specific force was rotated into t...

In medical application the multimodal image fusion is an important tool. It has developed with the advent of various imaging modalities in medical imaging. It is mostly used for the medical diagnosis. In this proposal a novel fusion technique is proposed for the multi modal medical image based on the NSCT (non-sub sampled Contourlet transform). In this algorithm high frequency and low frequency...

The novel high performance adaptive fidelity algorithms for automated multi-modality images’ feature detection, registration, and fusion is presented. The new fusion method, which consists of the Adaptive Fidelity Exploratory Algorithm (AFEA) and the Heuristic Optimization Algorithm (HOA), implements automatic adaptation from frame to frame with a few tunable thresholds. The new algorithms have...

One of the paramount problems manifest in modern cosmological theories is that of the initial singularity. Gasperini and Veneziano have proposed the pre-big-bang (PBB) model [2] based on the assumption that the Universe evolved out of a ten-dimensional Minkowski spacetime which is an exact vacuum of string theory, in hopes of resolving the singularity problem. Recently, Brandenberger, Easther a...

Frames consisting of translates of a single function play an important role in sampling theory as well as in wavelet theory and Gabor analysis. We give a necessary and sufficient condition for a subfamily of regularly spaced translates of a function φ ∈ L(R), (τnbφ)n∈Λ, Λ ⊂ Z, to form a frame (resp. Riesz basis) for its closed linear span. One consequence is that if Λ ⊂ N , then this family is ...

BACKGROUND Although its FDA-approved applications are limited, the pro-osteogenic benefits of recombinant human BMP-2 (rhBMP-2) administration have been shown in off-label surgical applications. However, the effects of rhBMP-2 on ankle fusions are insufficiently addressed in the literature, which fails to include a case-control study of adequate sample size to evaluate the efficacy of rhBMP-2 t...
