In this work, we introduce a fast and accurate method for unsupervised 3D medical image registration. This work is built on top of recent algorithm self-supervised anatomical embedding (SAM), which capable computing dense anatomical/semantic correspondences between two images at the pixel level. Our named SAM-enhanced registration (SAME), breaks down into three steps: affine transformation, coa...

S-adenosylmethionine (SAM) minimizes alcohol hepatotoxicity; however, the molecular mechanisms responsible for SAM hepatoprotection remain unknown. Herein, we use proteomics to determine whether the hepatoprotective action of SAM against early-stage alcoholic liver disease is linked to alterations in the mitochondrial proteome. For this, male rats were fed control or ethanol-containing liquid d...

Pascal’s mechanical calculator and Babbage’s Analytic Engine set the stage for a great deal of modern computing machinery. Modern versions of these concepts were finally realized in von Neumann’s architecture in about 1950. However, the science of computing does not depend on physical implementations of these ideas, but rather on virtual machines—that is, abstractions that perform computations ...

Smoothing approaches to the Simultaneous Localization and Mapping (SLAM) problem in robotics are superior to the more common filtering approaches in being exact, better equipped to deal with non-linearities, and computing the entire robot trajectory. However, while filtering algorithms that perform map updates in constant time exist, no analogous smoothing method is available. We aim to rectify...

The suppressive effects on acute alcoholic liver injury of S-adenosylmethionine (SAM) and the sake yeast, Saccharomyces cerevisiae Kyokai No. 9, have been shown previously. To enhance the suppression of acute alcoholic liver injury by sake yeast, we prepared SAM-accumulating sake yeast (SAM yeast). Male C57BL/6 mice that had been fed on a diet containing 0.25% SAM yeast or sake yeast for two we...

Ethylene, a gaseous hormone in plants, is involved in the regulation of a wide range of plant physiological processes, including leaf abscission, fruit ripening, and flower senescence (Yang and Hoffman, 1984). SAM or Adomet synthetase (ATP:L-methionine S-adenosyltransferase; EC 2.5.1.6) catalyzes the conversion of Met to SAM in the presence of ATP and Mg2+, which is the first step in ethylene b...

The present study is to indicate that the comparison between sectoral production multipliers of an input-output (I/O) model and a social accounting matrix (SAM) framework is almost impossible without taking into account accounting balances and theoretical considerations. Theoretically, the I/O model provides the Leontief’s production function, on the basis of which sectoral output multiplier ca...

A further development of the synchronous array method (SAM) as a medium access control scheme for large-scale ad hoc wireless networks is presented. Under SAM, all transmissions of data packets between adjacent nodes are synchronized on a frame-byframe basis, and the spacing between concurrent cochannel transmissions of data packets is properly controlled. An opportunistic SAM (O-SAM) is presen...
