Traditional satellite scatterometer wind retrieval algorithms consist of point-wise wind estimation and pointwise ambiguity removal. Point-wise estimation yields multiple estimates, or ambiguities, for the average near-surface ocean wind in each scatterometer resolution element, requiring subsequent ambiguity removal. Even though some point-wise ambiguity removal techniques achieve a high skill...

BACKGROUND Pixel-wise, parametric T2* mapping is emerging as a means of automatic measurement of iron content in tissues. It enables quick, intuitive interpretation and provides the potential benefit of spatial context between tissues. However, pixel-wise mapping uses much lower SNR data to estimate T2* when compared to region-based mapping thereby decreasing both its accuracy and precision. In...

It is of great interest to find the minimum effective dose (MED) in dose-response studies. A sequence of decreasing null hypotheses to find the MED is formulated under the assumption of nondecreasing dose response means. A step-up multiple test procedure that controls the familywise error rate (FWER) is constructed based on the maximum likelihood estimators for the monotone normal means. When t...

We propose the B c → B * u γ decay as the most suitable probe for the flavour changing neutral transition c → uγ. We estimate the short and long distance contributions to this decay within the standard model and we find them to be comparable; this is in contrast to radia-tive decays of D mesons, that are completely dominated by the long distance contributions. Since the c → uγ transition is ver...

This study presents a novel category of Transformer architectures known as comb transformers, which effectively reduce the space complexity self-attention layer from quadratic to sub-quadratic level. is achieved by processing sequence segments independently and incorporating X -word embeddings ...

Among various network compression methods, pruning has developed rapidly due to its superior performance. However, the trivial threshold limits performance of pruning. Most conventional methods are based on well-known hard or soft techniques that rely time-consuming handcrafted tests domain experience. To mitigate these issues, we propose a simple yet effective general method from an optimizati...

This paper presents a method for pixel-wise segmentation of moving regions using sparse motion cues on an image from a freely moving camera. The main idea is to utilize residual motion, i.e., motion relative to a background, on sparse grid points. Our algorithm consists of three parts: global motion estimation, characterization of points based on sparse motion cue, and pixel-wise labeling of mo...
