Hierarchical spatial pyramid max pooling based on SIFT features and sparse coding for image classification

IET Computer Vision, 2013
It is essential to build good image representations for many computer vision tasks. In this study, the authors propose a hierarchical spatial pyramid max pooling method based on scale‐invariant feature transform (SIFT) features and sparse coding, which ...

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Solvent‐Mediated Reactivity Control of Lewis‐Paired Dopants as a Versatile Strategy for Tunable and Stable Doping of Organic Semiconductors

Advanced Materials, EarlyView.
Solvent‐mediated reactivity control of Lewis‐paired dopants enables highly efficient, finely tunable, and stable doping of organic semiconductors. The optimally doped semiconductor films exhibit superior thermoelectric performance and doping stability, feature delocalized polarons along structurally ordered polymer backbones, and outperform ...

Reading and proclaiming the Advent call of John the Baptist: An empirical enquiry employing the SIFT method

, 2014
Drawing on Jungian psychological type theory, the SIFT method of biblical hermeneutics and liturgical preaching suggests that the reading and proclaiming of scripture reflects the psychological type preferences of the reader and preacher.

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

Advanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

Advanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of
