Double Shrinking Sparse Dimension Reduction
IEEE Transactions on Image Processing, 2013Learning tasks such as classification and clustering usually perform better and cost less (time and space) on compressed representations than on the original data. Previous works mainly compress data via dimension reduction. In this paper, we propose "double shrinking" to compress image data on both dimensionality and cardinality via building either ...

Speckle Reduction by Double Recorded Holograms
Applied Optics, 1973A method of speckle reduction in holography for 2-D objects with minimum recording area is presented. The image is incoherently synthesized from the hologram double recorded with a set of random phase plates.

On the Impossibility of Dimension Reduction for Doubling Subsets of $\ell_{p}$
SIAM Journal on Discrete Mathematics, 2014Summary: A major open problem in the field of metric embedding is the existence of dimension reduction for \(n\)-point subsets of Euclidean space, such that both distortion and dimension depend only on the doubling constant of the point set, and not on its cardinality. In this paper, we negate this possibility for \(\ell_p\) spaces with \(p>2\).

Mechanism of Enzymatic Reduction of Steroid Double Bonds
European Journal of Biochemistry, 1973The rate‐limiting step in the enzymatic reduction of double bonds in some steroids was studied with the aid of deuterated water and NADPH labeled in the A‐and B‐position with deuterium. The following reactions were studied: conversion of progesterone into 5α‐pregnane‐3, 20‐dione, catalyzed by rat liver microsomes; conversion of progesterone into 5β ...

Double Reduction of Plastoquinone to Plastoquinol in Photosystem 1
Biochemistry, 2011In Photosystem 1 (PS1), phylloquinone (PhQ) acts as a secondary electron acceptor from chlorophyll ec(3) and also as an electron donor to the iron-sulfur cluster F(X). PS1 possesses two virtually equivalent branches of electron transfer (ET) cofactors from P(700) to F(X), and the lifetime of the semiquinone intermediate displays biphasic kinetics ...

Double Gloving: A Risk Reduction Strategy
The Joint Commission Journal on Quality and Safety, 2003The use of sterile surgical gloves has become the international standard of care in the perioperative environment. Yet the potential for barrier failure exists, with the subsequent potential for the transfer of pathogens to both the patient and the surgical team.

Modern Double-Reduction Traction Motor
Transactions of the American Institute of Electrical Engineers, 1946Incorporated in the modern double-reduction motor and gear unit are many new design features which have made it an outstanding motor for the past five years. Oil lubrication is provided for all gearing and bearings in the oil-tight double-reduction gear unit.
